Description

Technical Field

[0001] This utility model relates to a shower height adjustment mechanism, particularly to a shower arm height adjustment mechanism, and more specifically, to a height adjustment mechanism for two symmetrically arranged shower arms. Background Technology

[0002] Shower units can be categorized into three main types based on their installation method: shower heads, overhead showers, and shower arms. Shower heads are the most common, mounted on the wall. Overhead showers are suspended from the bathroom ceiling via a linkage. Shower arms are mostly used in conjunction with a seat, primarily for the elderly and those with disabilities. The vast majority of shower units have a fixed, non-adjustable height. While some shower units offer height adjustment, the adjustment mechanism is often simplistic and inconvenient. More importantly, the connections between components are loose, leading users to perceive the product as low-end due to perceived instability during adjustment, which negatively impacts sales. Utility Model Content

[0003] This utility model provides a shower height adjustment mechanism with a novel structure, convenient adjustment operation, and a compact structure with better stability, overcoming the shortcomings of the prior art. The technical solution adopted by this utility model to solve its technical problem is as follows:

[0004] A shower height adjustment mechanism includes a shower body for mounting the shower and a telescopic tube assembly for vertically raising and lowering the shower body. The telescopic tube assembly includes a telescopic inner tube and a fixed outer tube movably connected together. The inner and outer tubes are vertically arranged, with the upper end of the inner tube extending upwards from the outer tube and connecting to the shower body. The telescopic tube assembly also includes a slider, a base, a spring, and a control rod. The base has a step near its bottom, which presses against the lower end face of the inner tube. The portion above the step is inserted into the inner tube, and the side of the portion below the step is flush with the outer tube. The inner wall is interference-fitted. The base has a groove above its step. The slider is slidably disposed in the groove. The slider has a pin. The telescopic inner tube has a through hole aligned with the pin. The fixed outer tube has multiple vertically spaced stop holes corresponding to the pin. When the through hole is horizontally aligned with any of the stop holes, the spring pushes the pin into the through hole and the stop hole. The control rod is vertically movable and disposed in the telescopic inner tube and connected to the slider. When the control rod moves vertically, it can drive the slider to slide horizontally until the pin exits the stop hole.

[0005] In a preferred embodiment: the lower end of the control rod is connected to a lower connector, and the lower connector has symmetrically arranged downward extending latch arms on the left and right sides. The base has a relief groove corresponding to the latch arm, and the latch arm is hooked to the guide groove on the side wall of the slider through the relief groove. The guide groove is inclined.

[0006] In a preferred embodiment: the base is provided with a plurality of ribs evenly around its portion above the step, and the ribs are interference-fitted with the inner wall of the telescopic inner tube.

[0007] In a preferred embodiment: the top of the base is provided with a buckle, which is fastened to the telescopic inner tube.

[0008] In a preferred embodiment, a button is also included, which is disposed on the body, and pressing the button causes the control lever to move downward.

[0009] In a preferred embodiment, a lever is also included. The lever is disposed on the body, and the two ends of the lever are movably connected to the upper end of the control rod and the button, respectively. The telescopic inner tube is provided with a clearance hole corresponding to the lever. Pressing the button upward causes the control rod to move downward.

[0010] In a preferred embodiment: the upper end of the control rod is connected to an upper connector, and the upper connector is movably connected to the lever.

[0011] In a preferred embodiment: there are two telescopic tube assemblies, arranged symmetrically on the left and right; there are two levers, arranged symmetrically on the left and right; and the button is located between the two levers.

[0012] In a preferred embodiment: a reset spring is tensioned between the button and the body.

[0013] In a preferred embodiment: there are two shower units, which are symmetrically installed on the main body.

[0014] Compared with the prior art, this technical solution has the following advantages:

[0015] The part below the base step is interference-fitted with the fixed outer tube. When the telescopic inner tube moves up and down relative to the fixed outer tube, it can prevent the telescopic inner tube from shaking. The slider drives the pin to move laterally. The sliding connection between the slider and the slide groove is tighter, avoiding the feeling of the pin falling off during the movement. Therefore, the overall structure is compact and stable. Moreover, the adjustment operation only requires operating the control lever, making the adjustment operation convenient. Attached Figure Description

[0022] Figure 6 It is illustrated Figure 1 The diagram shows a side view of the shower height adjustment mechanism in the adjusted state. Detailed Implementation

[0023] Please refer to Figures 1 to 6 The shower height adjustment mechanism includes a body 20 for mounting the shower 10 and a telescopic tube assembly 30 for vertically raising and lowering the body. The shower 10 is connected to the body 20 and therefore rises and falls synchronously with the body. Thus, the telescopic tube assembly 30 also raises and lowers the shower 10, achieving the effect of height adjustment. In this embodiment, the shower 10 is a shower arm structure, but it could also be a top spray or a shower head structure.

[0024] The telescopic tube assembly 30 includes a telescopic inner tube 31 and a fixed outer tube 32 that are movably inserted together. The telescopic inner tube and the fixed outer tube are vertically arranged. The upper end of the telescopic inner tube extends upward out of the fixed outer tube and connects to the body 20. Therefore, during adjustment, the telescopic inner tube 31 drives the body 20 and the shower 10 to move vertically relative to the fixed outer tube 32.

[0025] The telescopic tube assembly 30 also includes a slider 33, a base 34, a spring 35, and a control rod 36. The base 34 has a step 341 near its bottom. The telescopic inner tube 31 is inserted into the base 34 from below, with the step 341 pressing against the lower end face of the inner tube 31. The portion above the step 341 is inserted into the inner tube 31, and the side of the portion below the step 341 is interference-fitted with the inner wall of the fixed outer tube 32. Therefore, the fixed outer tube 32 and the base 34 are tightly fitted. However, those skilled in the art will understand that this tight fit allows for relative movement when a normal person applies force; for example, a beverage bottle cap can be easily opened when a normal person applies force. Therefore, during adjustment, external force is used to push the telescopic inner tube 31, moving the base 34 along with it.

[0026] The base 34 has a groove 342 above its step 341, which is the part that extends into the telescopic inner tube 31. The slider 33 is slidably disposed in the groove 342, which is perpendicular to the vertical direction. The slider 33 has a pin 332, and the telescopic inner tube 31 has a through hole aligned with the pin 332. The fixed outer tube 32 has multiple stop holes distributed vertically at intervals corresponding to the pin 332. The spring 35 is disposed between the slider 33 and the base 34. When the through hole is laterally aligned with any of the stop holes, the spring 35 pushes the pin 332 into the through hole and the stop hole, at which point the telescopic inner tube 31 and the fixed outer tube 32 are locked, and the height of the shower 10 is fixed. The control lever 36 is vertically movable and is installed in the telescopic inner tube 31 and connected to the slider 33. When the height needs to be adjusted, the control lever 36 is operated. When the control lever 36 moves vertically, it can drive the slider 33 to slide horizontally until the pin 332 exits the stop hole, thus releasing the telescopic inner tube 31.

[0027] Preferably, the lower end of the control lever 36 is connected to a lower connector 362. Symmetrically arranged downward-extending latching arms 364 are provided on both sides of the lower connector. The base 34 has a clearance groove 343 corresponding to the latching arms. The latching arms 364 are engaged with a guide groove 334 on the side wall of the slider 33 via the clearance groove 343. The guide groove 334 is inclined. Thus, when the latching arms 364 move vertically, they can push the side wall of the guide groove 334, causing the slider 33 to move laterally. Because the latching arms remain connected to the guide groove, the two are rigidly linked, with no action delay, resulting in sensitive adjustment operation and reliable adjustment feel.

[0028] Preferably, the base 34 has a plurality of ribs 344 evenly arranged around its portion above the step, and the ribs 344 are interference-fitted with the inner wall of the telescopic inner tube 31. This improves the connection stability between the base 34 and the telescopic inner tube 31.

[0029] Preferably, the base 34 is provided with a buckle 345 at its top, and the buckle 345 is fastened to the telescopic inner tube 31. This improves the connection stability between the base 34 and the telescopic inner tube 31.

[0030] Preferably, it also includes a button 40, which is disposed on the body 20, and pressing the button causes the control lever 36 to move downward.

[0031] Preferably, the system further includes a lever 50, which is mounted on the body 20. The two ends of the lever 50 are movably connected to the upper end of the control rod 36 and the button 40, respectively. The telescopic inner tube 31 has a clearance hole corresponding to the lever 50. Pressing the button 40 upwards causes the control rod 36 to move downwards. Specifically, pressing the button 40 upwards raises one end of the lever 50 connected to the button 40, causing the other end connected to the control rod 36 to fall downwards, thus pushing the control rod 36 downwards. The downward movement of the control rod 36 pushes the slider 33 back, ultimately causing the pin 332 to withdraw from the gear position hole.

[0032] Preferably, the upper end of the control rod 36 is connected to an upper connector 366, and the upper connector 366 is movably connected to the lever.

[0033] Preferably, there are two telescopic tube assemblies 30, symmetrically arranged on the left and right, and two levers 50, symmetrically arranged on the left and right, with the button 40 located between the two levers 50. Therefore, pressing the button 40 can simultaneously control the unlocking of the telescopic tube assemblies 30 on both sides, making adjustment very convenient.

[0034] Preferably, the reset spring 60 is tensioned between the button 40 and the body 20.

[0035] Preferably, there are two shower units 10, which are symmetrically installed on the main body 20.

[0036] In this embodiment, the fixed outer tube 32 can be fixed to a wall or a chair, as long as the telescopic inner tube 31 can telescopically move relative to the fixed outer tube 32.

[0037] The above description is only a preferred embodiment of the present utility model, and therefore cannot be used to limit the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model patent and the contents of the specification should still fall within the scope of the present utility model.
