DESCRIPTION OF EMBODIMENTS

(16) The present invention will be further illustrated below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Also, it should be understood that those skilled in the art may make various modifications and changes after reading the contents in the present invention, and these equivalent forms also intended to fall within the scope of the appended claims of the present application.

Embodiment 1

(17) As shown in FIG. 1, a waterproof connecting structure according to the present embodiment includes an upper portion and a lower portion, wherein the lower portion includes a first hollow cylindrical body 1, the upper portion includes a second hollow cylindrical body 2, and the second body 2 is engaged and sheathed with the first body 1. The first body 1 can be disposed on a base and integrally formed with the base.

(18) In combination with FIGS. 2 to 9, the second body 2 is provided with a clamping slot 21, and the first body 1 is provided with a protruding part 11 for being rotationally clamping with the clamping slot 21. Preferably, the clamping slot 21 is arranged on an inner surface of the second body 2 clamping slot, and the protruding part 11 is arranged on an outer surface of the first body 1.

(19) The second body is configured to be engaged and sheathed with the first body so that rainwater can be prevented from flowing into the first body and a structure connected with the first body from the connection portion to cause damage to circuits inside. The second body is further configured to be connected to the first body by rotational clamping connection, allowing people to remove the second body only rotating the second body, which facilitates maintenance of internal circuit lines of the structure connected with the first body. Moreover, compared with a snap-fit connection and a fastening connection or the like, the rotational clamping connection is not easy to wear and has better durability. In addition, the design of hollow structures of the second body and the first body can make the cable pass through the interior of the second body and the first body, facilitating connecting together of internal circuits of the structure connected with the second body and the first body.

(20) Alternatively, the first body 1 is provided with a clamping slot, and the second body 2 is provided with a protruding part for being rotationally snapped onto the clamping slot.

(21) Preferably, a locking structure is further arranged between the first body 1 and the second body 2 for preventing relative rotation of the first body 1 and the second body 2. The locking structure may preferably be a button structure.

(22) In this embodiment, the locking structure is a bolt structure. Correspondingly, the second body 2 and the first body 1 are provided with bolt holes, so that the first body 1 will be further fixed with the second body 2 by bolts when the first body 1 is rotationally snapped onto the second body 2.

(23) The bolt structure is arranged to fix the second body and the first body, so that the second body and the first body can be rotated with the bolt unscrewed, which ensures the stability of the locking structure and easy operation for the use.

(24) Preferably, the first body 1 is provided with two protruding parts 11. Each protruding part 11 can matches the clamping slot 21 in different way. The protruding parts 11 are preferably symmetrical with respect to the axis of the first body 1.

(25) Arranging two protruding parts is to make stress asymmetrical and to reduce the pressure on the protruding parts, and since the protruding parts cannot cooperate with other non-corresponding clamping slots, users can have only one correct assembly method when assembling the antenna system, thereby avoiding assembly errors as much as possible, which causes mismatch between the bolt holes of the first body and the second body to make the bolts cannot be successfully mounted and to make the first body and the second body continue to rotate with each other, reducing the safety and stability of the entire system.

(26) As shown in FIG. 5, an upper end portion of the second body 2 is provided with a convex edge 22, and the convex edge 22 is provided with flow guiding ports 23 which communicate with the outside. As shown in FIGS. 6 and 7, the flow guiding ports 23 are configured as four water flow grooves 231 arranged around the convex edge 22, and each water groove 231 is provided with two flow guiding holes 232. Such arrangement can drain rainwater flowing to the second body to the outside of the antenna system, thereby preventing the rainwater from entering the interior of the structure connected with the first body. Thus, the flow guiding ports 23 are preferably disposed around the convex edge and surrounding the hollow part of the second body, increasing the waterproof performance of the waterproof connecting structure. The convex edge 22 can be square as shown in FIGS. 3-5, and can also be round as shown in FIGS. 8 and 9.

(27) Preferably, as shown in FIGS. 6 and 7, the inside of a top surface of the second body 2 is provided a notch 25, so that there is a gap between the top surfaces of both the first body and the second body when they are rotationally clamped.

(28) The notch 25 being arranged inside of the top surface of the second body, the rainwater will flow through the top end of the second body 2 to the gap between the first body 1 and the second body 2, so that another protection will form for preventing rainwater from flowing into the structure connected with the first body, which further improves the waterproof performance of the waterproof connecting structure.

Embodiment 2

(29) The present embodiment provides an antenna system with the waterproof connecting structure according to embodiment 1 including an upper portion and a lower portion, the lower portion containing a first hollow cylindrical body 1, the upper portion containing a second hollow cylindrical body 2 engaged and sheathed with the first body 1. As shown in FIGS. 10 and 11, the antenna system further includes a base 4 and an external antenna 3. The first body 1 is disposed on the base 4 and preferably integrally formed with the base 4. The second body 2 is connected with the external antenna 3 by a bolt structure.

(30) Preferably, the cable of the external antenna 3 penetrates into the base 4 from the middle of the first body 1 and the second body 2.

(31) The external antenna 3 is provided with a channel connected to the hollow structure of the second body 2, the base 4 is also provided with a channel connected to the hollow structure of the first body 1, so that the cable of the external antenna 3 can pass through the first body 1, the second body 2 and the channel of the base 4 to the base 4 via the channel of the external antenna 3.

(32) Preferably, the upper end portion of the second body 2 is provided with a convex edge 22, and the external antenna 3 is provided with a groove matching the convex edge 22. Through the cooperation of the groove and the convex edge, the external antenna can be stably placed on the second body 2, and rainwater is difficult to enter the base 4 and the external antenna 3 through the gap between the groove and the convex edge 22.

(33) As illustrated in FIG. 12, the groove 31 can be round, and correspondingly the convex edge 22 is also round.

(34) As illustrated in FIG. 13, the groove 32 can be square, and correspondingly the convex edge 22 is also square.

(35) Preferably, the outside of the groove is provided with a protrusion 34. The protrusion is engaged with and surrounds the outside of the convex edge 22 when the external antenna 3 is fixed with the second body 2. Such arrangement can lengthen the distance from the entrance of the gap between the groove and the convex edge to the top surface of the convex edge, so that rainwater needs to flow a longer distance to enter the base 4, and the waterproof performance of the entire system is thus further improved.

(36) The top surface of the convex edge 22 is further surrounded by bolt holes which are symmetrically arranged. Correspondingly, bolt holes are arranged in the groove, so that bolts can pass through the bolt holes, and the external antenna 3 can be fixed on the second body 2.
