Description

Technical Field

[0001] The utility model relates to a lifting shower bracket, belonging to the technical field of shower brackets. Background Art

[0002] A shower bracket is a support for fixing a shower head or a shower nozzle. In the existing market demand, shower brackets with adjustable height are very popular. Conventional shower brackets with adjustable height generally adjust the friction force between a friction block and a sliding groove. By controlling the pressure of the friction block on the sliding groove, the friction force of the sliding groove on the friction block is indirectly controlled. Reducing the friction force facilitates sliding to adjust the height of the shower bracket. After the adjustment is in place, increasing the friction force for locking facilitates fixing the position for use.

[0003] Since the shower bracket used in the square shower rod sliding groove cannot be used with the shower bracket for the conventional round rod-shaped shower rod, and the friction force adjustment device in the shower bracket suitable for the square shower rod sliding groove in the prior art is relatively simple. Either it cannot be locked tightly after the adjustment is in place and is prone to sliding, or it is prone to being screwed too tightly during adjustment, resulting in easy damage to the thread. The adjustment and use are relatively inconvenient and need to be further improved. Content of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide a lifting shower bracket, which is adjusted by a knob and is convenient to use. Moreover, a limit protection is provided in the tightening and loosening adjustment component to avoid damage to the adjustment device caused by being screwed too loose or too tight during adjustment, and to ensure the stable and reliable use of the bracket.

[0035] The guiding and sliding assembly 1 includes a guiding and sliding main body 11, a locking pressing plate 12, and guiding rollers 13; the guiding and sliding main body 11 is fixedly connected to the bracket base 2; the locking pressing plate 12 is arranged to slide up and down in a guiding chute 111 in the guiding and sliding main body 11; a positioning protrusion 121 for fixing the lower end of the spring 43 is arranged inside the locking pressing plate 12, a through hole 112 for passing through the spring 43 is arranged in the guiding and sliding main body 11, and the position of the through hole 112 corresponds to the position of the nut sleeve 45; two guiding rollers 13 are clamped at both ends of the guiding and sliding main body 11 to guide the up and down sliding of the guiding and sliding assembly 1 in the chute of the shower rod; the diameter of the guiding roller 13 is slightly larger than the width dimension of the guiding and sliding main body 11. The locking pressing plate 12 is provided with a limiting protrusion 122, and a limiting groove 113 is arranged in the guiding chute 111. The limiting protrusion 122 slides up and down in the limiting groove 113 to limit the sliding stroke of the locking pressing plate 12.

[0036] The bracket base 2 includes an upper cover 21 and a lower cover 22; the upper cover 21 and the lower cover 22 are snap-connected together, the nut sleeve 45 is fitted in the lower cover 22, a connecting hole 211 for passing through the connecting rod of the knob 41 is arranged in the upper cover 21, and a connecting seat 212 for installing the shower holder 3 is arranged. A screw passing hole 213 is arranged in the connecting seat 212, and a mounting post 221 corresponding to the screw passing hole 213 is arranged in the lower cover 22. The shower holder 3 is arranged on the connecting seat 212 through a connecting screw 5. A limiting snap ring 411 is arranged on the connecting rod of the knob 41, and a tightening direction mark 412 and a rotation adjustment groove 413 are arranged on the knob 41 to facilitate rotation adjustment operation; a fixed snap ring 46 is arranged in the limiting snap ring 411, and the fixed snap ring 46 is used to prevent the knob 41 from coming out of the connecting hole 211.

[0037] The shower holder 3 includes a shower slot 31, a screw mounting hole 32, and a rotation limiting post 33. An elastic positioning post 34 is arranged in the hole of the rotation limiting post 33; a circle of positioning grooves 214 corresponding to the rotation position of the elastic positioning post 34 is arranged on the upper cover 21, and the head of the elastic positioning post 34 can extend into the positioning grooves 214 movably to maintain the rotation angle of the shower holder 3. A retaining ring 215 is arranged on the upper cover 21, and the side of the retaining ring 215 abuts against the side of the rotation limiting post 33 to limit the rotation angle of the shower holder 3. An adjusting gasket 6 is arranged between the connecting screw 5 and the connecting seat 212.

[0038] The working principle of the present utility model is as follows:

[0039] The utility model is slidably installed in a chute (not shown in the figure) of a shower rod. When a user rotates the knob 41 in the loosening direction, the knob 41 engages and rotates the rotating shaft rod 42, driving the lifting thread sleeve 44 to rotate. The clamping step 441 also rises accordingly, and the gap between the clamping step 441 and the locking pressing plate 12 widens. The spring 43 gradually extends to reduce the pressure on the locking pressing plate 12, thereby reducing the pressure of the locking pressing plate 12 on the chute of the shower rod, enabling the guiding sliding assembly 1 to slide up and down by means of the guiding rollers 13.

[0040] A clamping step 441 is provided at the lower part of the lifting thread sleeve 44. When the lifting thread sleeve 44 rotates and rises to a certain extent, the upper edge of the clamping step 441 abuts against the lower end of the nut sleeve 45 to prevent the knob 41 from continuing to rotate and prevent it from rotating too loosely.

[0041] When the lifting thread sleeve 44 rotates downward, it pushes the locking pressing plate 12 to move outward through the spring 43. When the locking pressing plate 12 moves to a certain extent, the limiting protrusion 122 therein abuts against the step of the non-through limiting groove 113, and the locking pressing plate 12 no longer moves outward; this avoids damage to components such as the knob 41 and the lifting thread sleeve 44 caused by over-rotation.

[0042] The shower head holder 3 of the utility model can rotate. When the shower head holder 3 rotates, the rotating limiting post 33 inside the shower head holder 3 drives the elastic positioning post 34 to move in a circular motion, enabling the end of the elastic positioning post 34 to continuously cooperate dynamically with different positioning grooves 214, facilitating the rotation of the shower head holder 3 to the required angle and then maintaining this rotation angle without external force. An adjusting gasket 6 is provided between the connecting screw 5 and the connecting seat 212 to facilitate the adjustment of the friction damping.

[0043] The above is only the specific implementation manner of the utility model, and does not limit the patent scope of the utility model. Any equivalent structural transformation made by using the content of the specification and drawings of the utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the utility model by the same token.
