[0038] Reference Figure 1 , Figure 2 and Figure 3A shower door includes a door frame 100, a fixed door 200 and a movable door 300. The door frame 100 includes an upper frame bar 110 and a lower frame bar 120. The fixed door 200 is fixedly arranged between the upper frame bar 110 and the lower frame bar 120. There are two movable doors 300, each of which is provided with a pulley assembly 400. The movable door 300 is slidably connected to the door frame 100 through the pulley assembly 400 and can move left and right relative to the fixed door 200. The shower door has an open state and a closed state. When in the open state, the two movable doors 300 are folded at the rear side of the fixed door 200. When in the closed state, refer to Figure 1 The two movable doors 300 are unfolded relative to the fixed door 200. A linkage structure is provided between the two movable doors 300 and the linkage structure is linked. The linkage structure includes a linkage member 510 and a linkage wheel 520. Figure 1 The movable door 300 on the middle right side, the pulley assembly 400 thereon, the linkage member 510 and other components together constitute the linkage door mechanism of the first embodiment of the utility model.

[0039] Reference Figures 3 to 7 In the linkage door mechanism, a first adjustment structure is provided between the linkage member 510 and the pulley assembly 400 and connected through the first adjustment structure. The first adjustment structure has an adjustment state and a locking state. When the first adjustment structure is in the adjustment state, the linkage member 510 can move relative to the pulley assembly 400 to adjust the installation position. When the first adjustment structure is in the locking state, the linkage member 510 is fixed relative to the pulley assembly 400.

[0040] During assembly, the linkage 510 is connected to the movable door 300 through the pulley assembly 400, and the movable door 300 is slidably connected to the door frame 100 through the pulley assembly 400. By setting the first adjustment structure, the first adjustment structure is in an adjustment state. At this time, the linkage 510 can be operated to move relative to the pulley assembly 400 to adjust the installation position. After the position is adjusted, the first adjustment structure is put into a locked state, and the linkage 510 is fixed relative to the pulley assembly 400 to lock its installation position, thereby adapting to the installation position deviation caused by production errors, and adjusting the linkage 510 to a suitable installation position, which is beneficial to avoid jamming or linkage failure when the movable door 300 moves due to the deviation of the linkage 510, and is easy to use.

[0041] In actual application, the specific structures of the linkage member 510, the pulley assembly 400 and the first adjustment structure can be set accordingly according to actual use needs, which will not be described in detail here and will be explained in detail below.

[0042] In some embodiments, the first adjustment structure includes a first threaded member 410, a first adjustment hole 511 and a first threaded hole 421. The first adjustment hole 511 is strip-shaped and is arranged on the linkage member 510. The first threaded hole 421 is arranged on the pulley assembly 400. The first threaded member 410 passes through the first adjustment hole 511 and is threadedly matched with the first threaded hole 421. The first threaded member 410 can move relative to the first adjustment hole 511. The first threaded member 410 can abut against the linkage member 510 and make the linkage member 510 abut and fixed to the pulley assembly 400.

[0043] It is understandable that if Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the first threaded member 410 is a bolt, and the first adjustment hole 511 is a waist-shaped hole, which is in the shape of a strip extending up and down. The first adjustment hole 511 is arranged on the linkage member 510, and the first threaded hole 421 is arranged on the pulley assembly 400. The first threaded member 410 passes through the first adjustment hole 511 and is threadedly matched with the first threaded hole 421. By loosening or tightening the first threaded member 410, the first adjustment structure can be switched between the adjustment state and the locking state. When in use, the first threaded member 410 can be loosened to put the first adjustment structure in an adjustment state. At this time, the linkage member 510 can be operated to move relative to the pulley assembly 400, so that the first threaded member 410 can move relative to the first adjustment hole 511 to adjust the installation position of the linkage member 510; after the adjustment is completed, the first threaded member 410 is tightened to put the first adjustment structure in a locked state. At this time, the front end of the first threaded member 410 abuts against the linkage member 510 and the linkage member 510 abuts and is fixed to the pulley assembly 400, thereby fixing the position of the linkage member 510. Its structure is simple and easy to adjust and use.

[0044] In actual application, in addition to the above structure, the first adjustment structure may also include a slide rail and a slider. The slide rail can be arranged on the linkage part 510 or the pulley assembly 400. The slider can be correspondingly arranged on the pulley assembly 400 or the linkage part 510 through a threaded part. The slider cooperates with the slide rail so that the linkage part 510 can move relative to the pulley assembly 400 to achieve position adjustment. After the adjustment is completed, the threaded part can be tightened to make the slider press the slide rail to achieve position locking. The specific changes can be made according to actual use needs.

[0045] Furthermore, a tooth surface structure 401 is provided on the side of the linkage member 510 facing the pulley assembly 400 and on the side of the pulley assembly 400 facing the linkage member 510 , and the linkage member 510 and the pulley assembly 400 can abut against each other through the tooth surface structure 401 .

[0046] It is understandable that if Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the rear side of the linkage 510 faces the pulley assembly 400, and the front side of the pulley assembly 400 faces the linkage 510. The rear side of the linkage 510 and the front side of the pulley assembly 400 are both provided with a tooth surface structure 401. When in use, the linkage 510 and the pulley assembly 400 can abut against each other through the tooth surface structure 401, and the tooth surfaces are meshed with each other, thereby achieving a relatively stable position locking effect. In actual application, the linkage 510 and the pulley assembly 400 can also be relatively fixed simply by abutting friction, which can be set accordingly according to actual use needs.

[0047] Furthermore, the pulley assembly 400 includes a first clamp seat 430, a second clamp seat 440 and a second threaded member 420. The first clamp seat 430 and the second clamp seat 440 are respectively arranged on both sides of the movable door 300 and are connected by the second threaded member 420 so as to be able to clamp the movable door 300. A pulley member 450 is rotatably arranged on the first clamp seat 430 and / or the second clamp seat 440.

[0048] It is understandable that if Figure 4 , Figure 5 and Figure 6 As shown, the first clamping seat 430 is located at the front side of the movable door 300, the second clamping seat 440 is located at the rear side of the movable door 300, and a pulley member 450 is rotatably provided on the second clamping seat 440. The first clamping seat 430 and the second clamping seat 440 are connected by a second screw member 420 so as to clamp the movable door 300, thereby realizing the installation connection between the pulley assembly 400 and the movable door 300, and the structure is simple; since the linkage member 510 is connected to the pulley assembly 400, the trouble of opening a hole on the movable door 300 for installation or setting other components to connect the linkage member 510 can be reduced, and it is convenient to use. In actual application, the specific structure of the pulley assembly 400 can also be changed accordingly according to actual use needs, such as the positions of the first clamping seat 430 and the second clamping seat 440 are interchanged, and the pulley member 450 is connected to both the first clamping seat 430 and the second clamping seat 440.

[0049] Furthermore, a cushion 460 is provided on the side of the first clamping seat 430 facing the movable door 300 and on the side of the second clamping seat 440 facing the movable door 300. It is understandable that Figure 4 , Figure 5 and Figure 6 As shown, the back side of the first clamping seat 430 and the front side of the second clamping seat 440 are both provided with a soft pad 460. The soft pad 460 is provided to prevent the first clamping seat 430 and the second clamping seat 440 from clamping the movable door 300, and is convenient for use. In actual application, the soft pad 460 can be a rubber pad or a silicone pad, etc., which is not limited here.

[0050] In some embodiments, reference Figure 2 and Figure 3The pulley assembly 400 is slidably matched with the upper frame bar 110, a guide wheel 320 is provided on the lower side of the movable door 300, and a guide groove 121 is correspondingly provided on the lower frame bar 120. The guide wheel 320 is located in the guide groove 121 and cooperates with the guide groove 121 to guide the movement of the lower side of the movable door 300.

[0051] In some embodiments, a second adjustment structure is provided between the movable door 300 and the pulley assembly 400 , and the pulley assembly 400 can adjust the installation position relative to the movable door 300 through the second adjustment structure.

[0052] It is understandable that if Figure 3 As shown, there are two pulley assemblies 400 on the same movable door 300, and the two pulley assemblies 400 are spaced apart in the left-right direction. By setting a second adjustment structure, the pulley assembly 400 can adjust the installation position relative to the movable door 300 through the second adjustment structure, which facilitates the leveling between multiple pulleys and makes the multiple pulley assemblies 400 in the same horizontal position; and when the movable door 300 is connected to the door frame 100 through the pulley assembly 400, it is also beneficial to adjust the matching condition of the guide wheel 320 and the guide groove 121, which is convenient for use.

[0053] In some embodiments, the second adjustment structure includes an adjustment block 310 and a second adjustment hole 301, the second adjustment hole 301 is provided in the movable door 300, the adjustment block 310 is provided in the second adjustment hole 301 and can rotate relative to the second adjustment hole 301, a connecting hole 311 is provided on the adjustment block 310, the connecting hole 311 is eccentrically arranged relative to the rotation axis of the adjustment block 310, a shaft 441 is provided on the first clamp seat 430 and / or the second clamp seat 440, the shaft 441 is inserted into the connecting hole 311 and cooperates with the connecting hole 311, the first clamp seat 430 and the second clamp seat 440 can clamp and fix the adjustment block 310.

[0054] It is understandable that if Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the movable door 300 is provided with a second adjustment hole 301, and the second adjustment hole 301 is a round hole. The adjustment block 310 is arranged in the second adjustment hole 301 and cooperates with the second adjustment hole 301, and can rotate relative to the second adjustment hole 301. The adjustment block 310 is provided with an eccentrically arranged connecting hole 311, and the second clamp seat 440 is provided with a shaft 441, and the shaft 441 is inserted into the connecting hole 311 and cooperates with the connecting hole 311. The shaft 441 is provided with a second threaded hole 442, and the second threaded member 420 passes through the first clamp seat 430 and is threadedly cooperated with the second threaded hole 442. During adjustment, the second threaded member 420 is loosened so that the first clamping seat 430 and the second clamping seat 440 do not clamp the movable door 300 and the adjusting block 310. At this time, the adjusting block 310 can be rotated. Since the connecting hole 311 is eccentric, the shaft 441 is driven to rotate, thereby adjusting the up, down, left and right positions of the first clamping seat 430 and the second clamping seat 440. After the adjustment is completed, the second threaded member 420 is tightened so that the first clamping seat 430 and the second clamping seat 440 clamp the movable door 300 and the adjusting block 310, thereby achieving position fixing. The structure is simple and easy to adjust.

[0055] In actual application, the second adjustment structure may also adopt the adjustment method of the first adjustment structure, or the first adjustment structure may also adopt the adjustment method of the second adjustment structure, which may be changed accordingly according to actual use needs.

[0056] Furthermore, an operating hole 312 is provided on the adjustment block 310. It is understandable that Figure 4 , Figure 6 and Figure 7 As shown, by providing the operating hole 312, the adjusting block 310 can be rotated relative to the second adjusting hole 301 through the operating hole 312, which is convenient for operation. In actual application, the position, size, shape, etc. of the operating hole 312 can be set accordingly according to actual use needs.

[0057] In some embodiments, the first threaded hole 421 is provided on the second threaded member 420. It is understood that Figure 5 , Figure 6 and Figure 7 As shown, the second threaded member 420 is a bolt with internal and external threads, and the first threaded hole 421 is provided on the second threaded member 420, thereby reducing the trouble of machining threaded holes on the first clamping seat 430 or the second clamping seat 440, simplifying the structure, saving component settings, and facilitating use. In actual application, the first threaded hole 421 can also be provided on the first clamping seat 430, which can be set accordingly according to actual use needs.

[0058] In some embodiments, reference Figure 1 , Figure 2 , Figure 3 and Figure 8When the shower door is in a closed state, of the two movable doors 300, the one located on the far right is the active door, and the one located in the middle is the driven door. The linkage wheel 520 is arranged on the pulley assembly 400 located on the driven door. The linkage between the active door and the driven door is achieved in the following manner: the upper and lower sides of the linkage wheel 520 are in rolling contact with the upper frame bar 110 and the linkage member 510 respectively. When the active door is pushed to move left and right, the linkage member 510 moves with the active door. The rolling friction between the linkage member 510 and the linkage wheel 520 is used to rotate the linkage wheel 520, and the linkage wheel 520 rotates relative to the upper frame bar 110, thereby moving left and right along the upper frame bar 110, driving the driven door to move left and right, thereby achieving linkage.

[0059] In practical application, in addition to the above linkage mode, a gear rack structure can also be set for linkage, such as the linkage member 510 is a rack, the linkage wheel 520 is a gear, or the two movable doors 300 can also be linked by a synchronous pulley structure, and the specific linkage structure can be set accordingly according to actual use needs. Since the structure of the linkage structure of the embodiment of the utility model is known to ordinary technicians in this field, it will not be described in detail here.

[0060] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
