(8) As shown in FIG. 1, a reinforced punch-free arcuate shower curtain rod mainly relates to a rod structure specially designed for separating a larger shower space at the corner of the bathroom. A structure of the shower curtain rod is mainly composed of a base 1, a sleeve 2, a short tube 3, an inner tube 4, and an outer tube 9.

(9) The base 1 is an important component for tightly pressing against two ends of the shower curtain rod against wall surfaces on two sides. A PVC gasket 5 is disposed on a bottom surface of each base 1. A front end of the sleeve 2 is radially swingably connected to the base 1. The specific structure is as follows. A mounting groove 11 having an axis extending in a radial direction is provided on the base 1. The front end of the sleeve 2 is disposed in the mounting groove 11, and forms reciprocating rotation in the radial direction of the mounting groove 11 after being threaded and tightened by a bolt 12 connected to a nut 13.

(10) A decorative cover 14 is disposed on the base 1, so as to cover the connecting structure between the front end of the sleeve 2 and the base 1, thereby causing the entire base 1 to be aesthetic.

(11) A front end of the short tube 3 and a rear end of the sleeve 2 are coaxially rotatably connected. The specific structure is shown in FIG. 2. A front sleeve 8 for fixed insertion is disposed on the front end of short tube 3. The structure for fixed insertion is usually connected as a whole by means of a stamping process. A ball head 82 is disposed on a front end of the front sleeve 8. A ring rib 83 is disposed on an outer circumferential surface of the ball head. A ball groove 22 for matedly assembling the ball head 82 is correspondingly provided on the rear end of the sleeve 2. A ring groove 23 is provided on an inner circumferential surface of the ball groove. In this way, the ball head 82 is rotatably assembled in the ring groove 23 of the ball groove 22 by using the ring rib 83, so that the sleeve 2 is coaxially rotatably connected to the short tube 3.

(12) A screw rod 7, a screw sleeve 71 threadedly sleeved on the screw rod, and a retainer ring 74 disposed on a rear end of the screw rod are disposed in the short tube 3. The retainer ring may be used to prevent the screw sleeve 71 from falling off due to an excessively large thread rotation stroke on the screw rod 7. A non-circular hole 81 formed along the axis is provided in the front sleeve 8. A non-circular shaft 72 is disposed on a front end of the screw rod 7. For example, a rectangular hole and a rectangular shaft are selected in this embodiment. The front end of the screw rod 7 is positioned and matedly inserted into the non-circular hole 81 of the front sleeve 8 by using the non-circular shaft 72, and then a screw 73 is threaded in the non-circular hole and is connected to the non-circular shaft 72, so that the front sleeve 8 and the screw rod 7 are fixed as a whole. That is to say, the screw rod 7 is coaxially fixedly mounted in the short tube 3.

(13) A rear end of the inner tube 4 is telescopically sleeved in the outer tube 9. The inner tube 4 and the outer tube 9 are both arcuate tubes. A set screw 91 for locking, extension, and retraction is disposed on the outer tube 9.

(14) In addition, a fastening groove 41 and a fastening rib 92 that are matedly assembled are respectively provided on an outer surface of the inner tube 4 and an inner surface of the outer tube 9 shown in FIG. 4 and FIG. 5. The fastening groove 41 is formed by axially extending along the outer surface of the inner tube 4, and the fastening rib 92 is formed by axially extending along the inner surface of the outer tube 9. The design purpose of using the structure is as follows. When the inner tube 4 and the outer tube 9 are tensioned with each other by means of locking, extension, and retraction, an inner wall of the fastening groove 41 and an outer wall of the fastening bar 92 are squeezed and in close contact with each other. This is to say, the contact friction between the inner tube 4 and the outer tube 9 is increased. Therefore, by means of the dual action of the set screw 91 and the contact friction force, the tensioning force between the arc-shaped inner tube and outer tube is increased, and the bases 1 at two ends of the arcuate shower curtain rod can be firmly attached to the wall surface, thereby enhancing the load-bearing capacity of the arcuate shower curtain rod.

(15) The front end of the inner tube 4 extends into the rear end of the short tube 3 to be fixedly connected to the screw sleeve 71 by means of fixed insertion. A rear sleeve 10 for fixed insertion is disposed on the rear end of the short tube 3. The front end of the inner tube 4 is inserted through the rear sleeve 10 into the rear end of the short tube 3, so as to separate the short tube 3 from the inner tube 4, thereby preventing the inner tube 4 from being scratched during rotation of the short tube 3.

(16) Therefore, when the short tube 3 drives the screw rod 7 to rotate synchronously during rotation forward and backward, the rotation of the screw rod is converted to drive the screw sleeve 71 and the inner tube 4 to simultaneously move axially and telescopically along the screw rod 7. The purpose is to conveniently adjust the pressing force on the base 1 during mounting of the arcuate shower curtain rod.

(17) In addition, the arcuate shower curtain rod further includes the pressing member 6. A double-sided adhesive 61 is disposed on a bottom surface of the pressing member, and is matedly mounted in a groove 63 on the bottom surface of the pressing member 6. A positioning block 62 is disposed on the pressing member 6. Correspondingly, a positioning hole 15 for positioning and assembling the positioning block 62 is provided on the base 1. The positioning block 62 and the positioning hole 15 are respectively a non-circular block and a non-circular hole. For example, a rectangular block and a rectangular hole are used in this embodiment.

(18) A through hole 51 is provided on the PVC gasket 5. Therefore, the positioning block 62 needs to pass through the through hole 51 and positioned and assembled in the positioning hole 15. The PVC gasket 5 is tightly mounted to the bottom surface of the base 1. That is, the base 1 is positioned and assembled on the positioning block 62 together with the PVC gasket 5 on the bottom surface. A counter bore 52 further requires to be provided on the bottom surface of the PVC gasket 5. The counter bore and the through hole are coaxial, so that the double-sided adhesive 61 on the bottom surface of the pressing member 6 and the PVC gasket 5 are on a same plane.

(19) In addition, the positioning block 62 is inserted through the base 1 to be pressed against and in contact with a cambered surface of the front end of the sleeve 2. The specific structure is as follows. An outer cambered head 21 is disposed on the front end of the sleeve 2. When the front end of the sleeve 2 is radially swung relative to the base 1, the outer cambered head 21 is always pressed against and in contact with the positioning block 62.

(20) An end of the outer tube 9 is directly connected to the base 1 by using a plug 94. The plug and the end of the outer tube 9 are mainly fixed by the screw inserted through a connecting hole 93. Moreover, the connection structure between the plug 94 and the base 1 is actually the same as that between the sleeve 2 and the base 1 in the inner tube 4. Therefore, details will not be described herein again.

(21) According to the disclosure, the pressing member 6 is creatively added to the arcuate shower curtain rod. Therefore, during use, the pressing member 6 may be first accurately pasted on the mounting position of the wall surface by using the double-sided adhesive 61 on the bottom surface of the pressing member 6, thereby avoiding punching holes on the wall surface. Then the base 1 is positioned and assembled on the positioning block 62 of the pressing member 6 together with the PVC gasket 5 on the bottom surface. Mounting positions of two ends of the base 1 are predetermined by using the pressing member 6, thereby avoiding the trouble for incapability of determining the mounting position of the base and the requirement for continuous adjustment after the base 1 is pressed during the mounting of the traditional arcuate shower curtain rod.

(22) In addition, the base 1 can also be in contact with the wall surface by means of the friction force between the PVC gaskets 5 and the adhesive force of the double-sided adhesive 61, so that the base 1 is mounted extremely firmly and stably and have a higher bearing strength.

(23) In addition, the positioning block 62 of the pressing member 6 is inserted through the base 1 to be pressed against and in contact with the outer cambered head 21 of the front end of the sleeve 2. Therefore, even if the front end of the sleeve 2 is radially swung relative to the base 1 for fine adjustment, the front end of the sleeve is maintained to be in contact with and pressed against the pressing member 6 by using the outer cambered head 21, so that the pressing force on the base 1 does not weaken during the fine adjustment, thereby avoiding the injury caused by the accidental fall of the base 1 from the wall surface.

(24) The foregoing descriptions are merely specific embodiments of the disclosure. A person skilled in the art should understand that any structure design similar to the embodiments shall fall within the protection scope of the disclosure.
