[0097] Specifically, the two pipe fittings are connected end-to-end into the pipe clamp 100, and the ends of the pipe fittings are positioned through the positioning protrusions. The positioning protrusions are integrally formed with the first coupling section 11 and the second coupling section 12, and the structure is firm, which is different from the flexible positioning of the tongue portion of the sealing member, the positioning is more firm. The positioning protrusions arranged on the first coupling section 11 are symmetrically distributed with the positioning protrusions arranged on the second coupling section 12. The number of positioning protrusions can be multiple, and the size is set according to actual requirements. The positioning protrusions on the first coupling section 11 and the positioning protrusions on the second coupling section 12 are symmetrically distributed to ensure the reliability of positioning.

[0098] The pipe clamp provided in this embodiment is described by taking two positioning protrusions as examples. Referring to FIG. 2, a first coupling section 11 is provided with a first positioning protrusion 101, and a second coupling section 12 is provided with a second positioning protrusion 102.

The first positioning protrusion 101 and the first coupling section 11 are integrally cast, and the second positioning protrusion 102 and the second coupling section 12 are integrally cast to ensure the stability of the first positioning protrusion 101 and the second positioning protrusion 102.

[0100] The first positioning protrusion 101 is arranged at the geometric center of the inner wall of the first coupling section 11; The second positioning protrusion 102 is arranged at the geometric center of the inner wall of the second coupling section 12.

[0103] Referring to FIGS. 1-2, in an optional embodiment, the first connecting mechanism includes a first bolt 103, a first bolt hole 104 arranged at one end of the first coupling section 11 and a second bolt hole 105 arranged at one end of the second coupling section. The first bolt 103 passes through the first bolt hole 104 and the second bolt hole 105 to realize the connection of one end of the first coupling section 11 and one end of the second coupling section 12. The second connecting mechanism includes a second bolt 106, a third bolt hole 107 arranged at the other end of the first coupling section 11 and a fourth bolt hole 108 arranged at the other end of the second coupling section 12. The second bolt 106 passes through the third bolt hole 107 and the fourth bolt hole 108 to realize the connection of the other end of the first coupling section 11 and the other end of the second coupling section 12. That is, both ends of the first coupling section 11 and the second coupling section 12 are connected by a screw connection, which is simple and reliable.

[0104] Referring to FIGS. 1-4, the pipe clamp 100 with double-bolt structure provided by the embodiment can be a rigid pipe clamp, and the connection of the first coupling section 11 and the second coupling section 12 is cooperatively connected through a mutually cooperated concave-convex structure 140.

[0105] Referring to FIGS. 6-10, the pipe clamp 100 with the double-bolt structure provided in this embodiment is a flexible pipe clamp, and the connection of the first coupling section 11 and the second coupling section 12 is an inclined port connection, that is, the connection of the first coupling section 11 and the second coupling section 12 is provided with a mutually cooperated inclined port structure 140.

[0106] Referring to FIGS. 11-15, as another optional embodiment, the first connecting mechanism includes a first bolt 103, a first bolt hole 104 arranged at one end of the first coupling section 11 and a second bolt hole 105 arranged at one end of the second coupling section. The first bolt 103 passes through the first bolt hole 104 and the second bolt hole 105 to realize the connection of one end of the first coupling section 11 and one end of the second coupling section 12. The second connecting mechanism includes a first separated pin 109 and a second separated pin 110 respectively extending from both sides of the other end of the first coupling section 11, and a separated column connector 111 extending from the other end of the second coupling section 12; a separated column 112 is connected to the separated column connector 111, and the separated column connector 111 extends and inserts between the first separated pin 109 and the second separated pin 110 so that the separated column 112 is against the first separated pin 109 and the second separated pin 110. The ends of the first separated pin 109 and the second separated pin 110 are provided with an arc-shaped surface matching the column 112, and the separated column 112 is against the arc-shaped surface. That is, one end of the first coupling section 11 is connected to one end of the second coupling section 12 with screws; and the other end of the first coupling section 11 is connected to the other end of the second coupling section 12 with pins. This connection can effectively improve the assembly efficiency.

[0107] One side of the outer surface of the first coupling section 11 is provided with a first reinforcing rib 113 connected with the first separated pin 109; the other side of the outer surface of the first coupling section 11 is provided with a second reinforcing rib 114 connected with the second separated pin. The first reinforcing rib 113 and the first separated pin 109 are integrally formed; the second reinforcing rib 114 is integrally formed with the second separated pin 110. A third reinforcing rib 115 and a fourth reinforcing rib 116 are respectively arranged on both sides of the outer surface of the second coupling section 12. The design of the reinforcing ribs on the first coupling section and the second coupling section can transmit the stress when the pipe clamp is locked to the other separated pin connectors and the other separated column connectors, reducing the stress concentration of the pipe clamp, and saving more materials and giving more effective play to its performance compared with the way of strengthening the strength by increasing the thickness.

[0108] Referring to FIGS. 5, 8 and 14, both sides of the inner surface of the first coupling section 11 are provided with a first arc segment 117 that is in contact with the pipe fitting. The first arc segment 117 is semi elliptical-shaped. The first radius a from the center of the first arc segment 117 to the end of the first arc segment 117 is greater than the second radius b from the center of the first arc segment 117 to the middle end of the first arc segment 117, and the first radius a is greater than the second radius b by about 1-5 mm. Referring to FIG. 15, both sides of the inner surface of the second coupling section 12 are provided with a second arc segment 118 that is in contact with the pipe fitting, and the second arc segment 118 is semi elliptical-shaped. The third radius c from the center of the second arc segment 118 to the end of the second arc segment 118 is greater than the fourth radius d from the center of the second arc segment 118 to the middle end of the second arc segment 118. The third radius c is greater than the fourth radius d by about 1-5 mm.

[0109] When the first coupling section 11 and the second coupling section 12 are bridged on the end-to-end pipe fittings, the inner part of the first coupling section 11 and the second coupling section 12 is formed in a nearly circular structure integrated closely with the pipe fittings fit. Since the contact part of the first coupling section 11 and the second coupling section 12 in contact with the pipe fittings are both semi elliptical-shaped, the enclosed shape is an ellipse, which make the fastening force at the time of connecting the two ends of the first coupling section 11 and the second coupling section 12 generate a centripetal deformation force through the lever torque produced by the cooperation of the longer radius and the shorter radius of the ellipse, so as to hold the pipe fittings tightly and make the inner walls of the first coupling section 11 and the second coupling section 12 fit the pipe fittings better.

[0110] Referring to FIGS. 16-18, the pipe clamp 100 provided by this embodiment includes a first coupling section and a second coupling section, which are used to fix the pipe fittings end-to-end together; one end of the first coupling section and one end of the second coupling section are connected through a first connecting mechanism, and the other end of the first coupling section and the other end of the second coupling section are connected through a second connecting mechanism; two positioning protrusions 119 are arranged on the inner wall of the first coupling section 11, and two positioning protrusions are arranged on the inner wall of the second coupling section. The two positioning protrusions 119 of the first coupling section 11 are respectively arranged at the positions close to the end of the inner wall of the first coupling section 11. Similarly, the two positioning protrusions of the second coupling section are respectively arranged at the positions close to the end of the inner wall of the second coupling section. The two positioning protrusions of the first coupling section and the two positioning protrusions of the second coupling section are symmetrical. The number and distribution of positioning protrusions can be set according to actual needs.

[0111] Referring to FIG. 19, the pipe clamp 100 provided by the embodiment includes a first coupling section and a second coupling section, which are used to fix the pipe fittings together end-to-end; one end of the first coupling section is screwed to one end of the second coupling section, and the other end of the first coupling section is screwed to the other end of the second coupling section; a first positioning protrusion 101 is arranged at the geometric center of the inner wall of the first coupling section 11, two positioning protrusions 119 are arranged close to the end, a second positioning protrusion is arranged at the geometric center of the inner wall of the second coupling section, and two positioning protrusions are arranged close to the end. The pipe fittings are firmly and reliably positioned by setting a positioning protrusion for positioning the pipe fittings on the inner walls of the first coupling section and the second coupling section in the pipe clamp 100 provided in this embodiment, which can effectively save materials and reduce production costs.

[0112] Referring to FIGS. 20 and 22, the second embodiment of the invention provides a pipe clamp assembly 200, including the pipe clamp 100 above and a sealing member 21 in cooperation with the pipe clamp 100;

[0113] The sealing member 21 is provided with positioning grooves matching the positioning protrusions.

[0114] The main body of the sealing member 21 is a circular ring structure, and the shape and number of positioning grooves are matched with the shape and number of positioning protrusions of the pipe clamp 100. Referring to FIGS. 1 and 2, the first coupling section 11 of the pipe clamp 100 is provided with a first positioning protrusion 101, the second coupling section 12 is provided with a second positioning protrusion 102, and the structure of the matched sealing member 21 is shown in FIG. 23.

The first positioning groove 201 and the second positioning groove 202 are symmetrical, the shape, size, depth and setting position of the first positioning groove 201 adapt to the first positioning protrusion 101, and the shape, size, depth and setting position of the second positioning groove 202 adapt to the second positioning protrusion 102. The depths of the first positioning groove 101 and the second positioning groove 102 are 2 mm-10 mm.

[0115] The sealing member 21 is used to prevent the fluid in the pipe fitting from leaking.

[0116] Referring to FIG. 24, a pair of notches 120 are formed at the connection of the first coupling section 11 and the second coupling section 12. When the first coupling section 11 and the second coupling section 12 are in a predetermined spacing relationship, the notch 120 provides a gap for inserting the end of the pipe fitting into the space between the first coupling section 11 and the second coupling section 12. The notch 120 forms an obvious gap after the pipe fitting is assembled. The sealing member is easy to be damaged under pressure at this position, and therefore the sealing member is under the risk of fluid ejection.

[0118] On the one hand, the setting of the first auxiliary positioning protrusion 203 and the second auxiliary positioning protrusion 204 can further ensure the effective positioning of the pipe fitting. On the other hand, it can also increase the thickness and pressure tolerant capability of this position to avoid the damage to this position, which cause the fluid ejection.

The sealing member 21 matching the pipe clamp is shown in FIG. 26. The sealing member 21 includes four positioning grooves 205. The shape, size and setting position of the positioning groove 205 are matched with the positioning protrusion 119.
