[0026] Reference Figure 1-6 The image shown is a preferred embodiment of the present invention.

[0027] The fixing device for the suspension support rod includes a base 30 for attaching to the wall, a support structure 10 for suspending the support rod connected to the base 30, a locking mechanism 20 for locking the support rod onto the support structure 10, a suction cup 31 on the back of the base 30, a threaded rod 32 fixedly connected to one end of the suction cup 31 facing the base 30, the threaded rod 32 being threadedly connected to the base 30, and a pressure cylinder 50 between the base 30 and the suction cup 31.

[0028] The aforementioned mounting device for the suspension support rod allows for drilling-free installation by directly adhering to the wall surface via the suction cup 31. The distance between the suction cup 31 and the base 30 can be adjusted by rotating the base 30 in conjunction with the threaded rod 32. The pressure cylinder 50 evenly distributes pressure when the suction cup 31 is under pressure, enhancing the adsorption stability. The support rod is suspended by the support structure 10 and locked onto the support structure 10 by the locking mechanism 20. The base 30, support structure 10, and locking mechanism 20 are designed as separate units, simplifying the installation process, reducing maintenance costs, and allowing users to replace damaged parts individually. This solves the problem that the mounting base 30 of the support rod requires drilling holes in the wall to fix the support rod.

[0029] The suction cup 31 fixing method is suitable for smooth surfaces such as tiles and glass, avoiding the damage to the wall caused by traditional drilling, and is especially suitable for rental scenarios.

[0030] In this embodiment, the support structure 10 includes a rod support 11 for suspending the support rod. The rod support 11 is connected to the base 30. The rod support 11 has a groove 12 with a top opening. The rod support 11 is provided with a sliding cavity communicating with the groove 12. The outer opening of the sliding cavity is located on the inner side wall of the groove 12. The locking mechanism 20 is located in the sliding cavity.

[0031] Top opening of bracket 12: Allows the support rod to be inserted directly from above without lateral sliding, simplifying the installation process and making it particularly suitable for operation in narrow spaces;

[0032] The sliding cavity has an outer opening: the concealed locking mechanism 20 is placed inside the rod support 11 to prevent exposed parts from snagging on the shower curtain or affecting the appearance, while also protecting the lock from moisture corrosion; the rod support 11 is directly connected to the base 30 to reduce the risk of loosening and ensure the overall rigidity of the support structure 10.

[0033] The bracket 12 is U-shaped; this increases the contact area between the support rod and the bracket 12, making it easier to wrap the support rod and increasing the stability of the support rod.

[0034] In this embodiment, the locking mechanism 20 includes an operating lever 21 and a gear plate 22. The gear plate 22 is located in the sliding cavity. One end of the operating lever 21 is fixed on the gear plate 22, and the other end of the operating lever 21 is exposed outside the lever support 11.

[0035] Gear shift slide 22 linked to operating lever 21: Users only need to push the exposed operating lever 21 to control the movement of the internal gear shift slide 22, realizing quick locking / unlocking of the support lever with one hand.

[0036] The operating lever 21 acts as a lever to amplify the force applied by the user, enabling the gear plate 22 to generate a greater clamping force and preventing the support rod from slipping off unexpectedly.

[0037] In this embodiment, a track groove 13 is provided on the outer side of the rod support 11 for the control trajectory of the operating rod 21. The track groove 13 is connected to the sliding cavity, and one end of the operating rod 21 passes through the track groove 13. In this way, the movement trajectory of the operating rod 21 can be constrained by the limiting design of the track groove 13, avoiding excessive pushing and pulling that could cause the mechanism to jam.

[0038] In this embodiment, a track protrusion is provided on the bottom of the sliding cavity, and the track protrusion slides in cooperation with the bottom of the stop plate 22.

[0039] The guide rail protrusion ensures that the gear shift slide 22 slides linearly without deviation, reduces friction loss, and extends the service life of the mechanism; the guide rail protrusion slides in cooperation with the bottom of the gear shift slide 22, reducing the contact area between the gear shift slide 22 and the sliding cavity, and improving the sliding effect of the gear shift slide 22.

[0040] In this embodiment, the track groove 13 has two opposing latching protrusions 14 on both sides, with a gap between the two latching protrusions 14. In this way, the two latching protrusions 14 can provide clear tactile feedback (such as a clicking sensation) to prompt the user that the latch is in place and limit the locking position of the operating lever 21.

[0041] In this embodiment, the rod support 11 and the base 30 are connected by an axial sleeve 40. The axial sleeve 40 is fastened to the base 30, and the rod support 11 is rotatably connected to the axial sleeve 40. In this way, when the base 30 and the threaded rod 32 are rotated for adjustment, the axial sleeve 40 will not cause the rod support 11 to rotate, thus improving the ease of installation.

[0042] In this embodiment, a mounting ring 15 protrudes from one side of the rod support 11, and the mounting ring 15 has an elastic locking protrusion 16. The mounting ring 15 is connected to the axial sleeve 40 through the locking protrusion 16. In this way, a rebound force can be generated by deformation to ensure that the mounting ring 15 and the axial sleeve 40 are tightly engaged, eliminating the shaking sensation during rotation.

[0043] In this embodiment, an annular locking groove 41 is formed by an inward recess on the inner side of the axial sleeve 40. The annular locking groove 41 is arranged circumferentially around the inner side of the axial sleeve 40, and the locking protrusion 16 is located in the annular locking groove 41.

[0044] 41 circumferential locking grooves: allow the rod support to rotate 11360° continuously for adjustment, without fixed angle limitations, meeting multi-directional installation requirements;

[0045] Anti-dislodgement design: The locking protrusion 16 forms a mechanical interlock after sinking into the annular groove, making it difficult to separate even under axial tension.

[0046] In this embodiment, a through hole 51 is provided in the middle of the pressure cylinder 50. The suction cup 31 passes through the through hole 51 via a threaded rod 32 and is threadedly connected to the base 30. This ensures that the threaded rod 32 is screwed vertically into the base 30, avoiding local stress concentration and detachment of the suction cup 31 due to skewness. The pressure cylinder 50 converts the force on the center of the suction cup 31 into annular surface pressure, improving the sealing performance of the suction cup 31's edges and preventing air leakage failure.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
