[0002] Most shower rooms on the market now use sliding doors. In order to reduce the failure rate and improve the safety and comfort of use, existing shower room doors are mostly equipped with buffers, which are installed at both ends of the door rails. Then, when the pulleys of the sliding door slide to both ends, the sliding door and the buffers are connected to achieve a buffering effect. The structure of the existing buffer includes a contact card and a buffer assembly connected to the contact card. When the sliding glass door approaches the buffer, the contact card block on the pulley moves with the sliding glass door to cooperate with the contact card and push the contact card, so that the contact card compresses the buffer assembly, so that the sliding glass door is decelerated and buffered. When the door is opened, the contact card block is separated from the contact card. However, most of the existing buffer shower rooms are top buffers, and the buffers are installed on the guide rails, which makes the frame of the shower room door wider and affects the appearance.

[0007] The pulley assembly according to the embodiment of the utility model has at least the following beneficial effects:
[0008] The utility model changes the traditional top-mounted installation mode of the buffer, and installs the contact card block on either the left or right side of the wheel frame. The position of the contact card block determines that the buffer can only be installed on the side, and the buffer and the pulley assembly are generally at the same horizontal height, so that the buffer can be hidden in the side of the upper guide rail of the shower door, does not occupy the top space of the upper guide rail, reduces the front width of the upper guide rail, and thus can obtain a shower door with an extremely narrow frame.
[0009] According to some embodiments of the present invention, the highest point of the contact block is lower than the highest point of the pulley, and the lowest point of the contact block is higher than the lowest point of the pulley.
[0010] According to some embodiments of the utility model, a symmetrical pulley block is provided on the wheel frame, and the symmetrical pulley block includes at least one pair of symmetrical pulleys, and each pair of symmetrical pulleys includes two first pulleys symmetrically arranged on the left and right sides of the wheel frame, and the contact block is fixedly connected to the wheel frame, and the contact block is located on one side of the symmetrical pulley block, and a second pulley is also provided on the wheel frame and the second pulley is located on the opposite side of the contact block. The above design makes the structure between each pulley and the contact block more compact, saves the horizontal width of the guide rail section, and reduces the use of guide rail materials. At the same time, it not only ensures the smoothness of the movement of the pulley assembly, but also ensures that the contact block can cooperate with the contact card of the buffer. The contact block is locked on the wheel frame by screws.
[0011] According to some embodiments of the utility model, the wheel frame is further provided with a third pulley, the third pulley and the contact block are located on the same side of the wheel frame, and the third pulley is located between the contact block and the symmetrical pulley assembly.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.
[0037] Reference Figure 1 A pulley assembly 400 includes a wheel frame 460 and at least two pulleys, the pulleys are respectively installed on the left and right sides of the wheel frame 460, and a contact block 410 is provided on either side of the left and right sides of the wheel frame 460. The highest point of the contact block 410 is higher than the lowest point of the pulley, and the lowest point of the contact block 410 is lower than the highest point of the pulley.
[0038] The utility model changes the traditional top-mounted installation method of the buffer 500, and installs the contact card block 410 on either the left or right side of the wheel frame 460. The position of the contact card block 410 determines that the buffer 500 can only be installed on the side, so that the buffer 500 and the pulley assembly 400 are generally at the same horizontal height. At this time, the buffer 500 can be hidden in the side of the upper guide rail 300 of the shower door, does not occupy the top space of the upper guide rail 300, and reduces the front width of the upper guide rail 300, thereby obtaining a shower door with an extremely narrow frame.
[0039] In some embodiments of the present invention, the highest point of the contact block 410 is lower than the highest point of the pulley, and the lowest point of the contact block 410 is higher than the lowest point of the pulley.
[0040] In some embodiments of the utility model, a symmetrical pulley block is provided on the wheel frame 460, and the symmetrical pulley block includes at least one pair of symmetrical pulleys, each pair of symmetrical pulleys includes two first pulleys 420 symmetrically arranged on the left and right sides of the wheel frame 460, and the contact block 410 is fixed to the wheel frame 460, and the contact block 410 is located on one side of the symmetrical pulley block, and the wheel frame 460 is also provided with a second pulley 440, and the second pulley 440 is located on the opposite side of the contact block 410. The above design makes the structure between each pulley and the contact block 410 more compact, saves the horizontal width of the guide rail section, and reduces the use of the guide rail material. At the same time, it not only ensures the stability of the movement of the pulley assembly 400, but also ensures that the contact block 410 can cooperate with the contact clamp 510 of the buffer 500. The contact block 410 is locked on the wheel frame 460 by screws.
[0041] In some embodiments of the present invention, a third pulley 450 is further provided on the wheel frame 460, and the third pulley 450 and the contact block 410 are located on the same side of the wheel frame 460, and the third pulley 450 is located between the contact block 410 and the symmetrical pulley set. The third pulley 450 is used to improve the balance of the pulley assembly 400.
[0042] In some embodiments of the present invention, the contact card block 410 is made of nylon. The existing contact card block 410 is made of stainless steel, which will make noise when the door is opened and closed. The contact card block 410 of the present invention is made of nylon, which makes less noise when the buffer 500 is triggered.
[0043] Reference Figure 2-10A shower room door includes a pulley assembly 400, a buffer 500 and an upper guide rail 300. The upper guide rail 300 is provided with a slide groove 310 for the pulley assembly 400 to slide and a cavity 320 for accommodating the buffer 500. The slide groove 310 is connected to the cavity 320. The pulley assembly 400 is placed in the slide groove 310. The buffer 500 is placed in the cavity 320. The buffer 500 includes a contact card 510 and a buffer assembly 520. When the pulley assembly 400 moves in the front-back direction, the contact card block 410 can be inserted into the contact card 510 and push the contact card 510 to compress the buffer assembly 520. The buffer 500 used in the utility model is an existing buffer 500.
[0044] In some embodiments of the present invention, the side of the pulley close to the wheel frame 460 is the inner side of the pulley, and the side away from the wheel frame 460 is the outer side of the pulley. The outer edge of the pulley protrudes radially to form a circle of flange 470, and the radius of the flange 470 is greater than the radius of the pulley body. The opening of the slide groove 310 is downward, and the two sides of the opening of the slide groove 310 protrude upward to form a retaining edge 311. The pulley assembly 400 is installed in the slide groove 310 through the cooperation of the flange 470 and the retaining edge 311 to limit the lateral movement of the pulley assembly 400. When the pulley assembly 400 slides and there is a horizontal deviation, the relative cooperation between the pulley flange 470 and the retaining edge 311 of the slide groove 310 can ensure that the pulley assembly 400 will not fall off the guide rail, thereby ensuring safety during operation.
[0045] In some embodiments of the present invention, the cross section of the retaining edge 311 is arc-shaped, and there is an arc transition surface between the flange 470 and the pulley body, and the arc radius of the arc transition surface is greater than the arc radius of the retaining edge 311 (such as Figure 3 As shown). When the pulley assembly 400 is biased to one side, the pulley always contacts the slide groove 310 at only one point, which reduces friction and increases the tendency of the pulley assembly 400 to return to horizontal. If the front and rear wheels of the traditional double-sided concave pulley are not on the same plane in the vertical direction, or the wheelbase is different from the distance between the guide rail rib 311, the pulley assembly 400 will swing left and right during the movement, and the pulley loss will increase. The pulley of the utility model is designed with a single-sided flange 470. Compared with the double-sided concave pulley, the utility model has lower processing accuracy requirements for the wheel frame 460 and lower pulley wear.
