[0038] A slider 3 for propping up the cavity wall 131 is installed in the gap adjustment cavity 13 . The slider 3 is installed in the gap adjustment cavity 13 so as to slide up and down. The slider 3 has a slider inclined surface 31 adapted to the guide inclined surface 132 .

[0039] The groove wall 12 is connected with an adjusting member 4 for adjusting the upward and downward movement of the slider 3 , and the slider 3 is connected to the adjusting member 4 .

[0040] The shower door top beam 100 provided by the present invention is used to be installed on the top of the shower door 400 to provide guidance and support for the top edge of the shower door 400 .

[0041] An upper roller 500 is disposed at the top edge 401 of the shower door 400 . The upper roller 500 is arranged horizontally, and a wheel axle 501 of the upper roller 500 is arranged vertically. The lower end of the wheel axle 501 is connected to the top edge 401 of the shower door 400 .

[0042] The shower door top beam 100 can be used as the top beam of the shower door frame, and the shower door frame includes the shower door top beam 100, the threshold beam 200 and two side frames 300. The threshold beam 200 is installed on the floor of the bathroom to play a water-proof role. A guide rail is provided on the threshold beam 200, and a lower roller is provided at the bottom of the shower door 400. The lower roller is assembled on the guide rail and can roll along the guide rail. Two side frames 300 are connected to both ends of the threshold beam 200, and the side frames 300 are fixed on the wall. The shower door top beam 100 is connected between the upper ends of the two side frames 300.

[0043] In some scenarios, both ends of the shower door top beam 100 can be directly fixed to the wall, and the shower door frame is no longer configured with a dedicated side frame 300.

[0044] The shower door top beam 100 provided by the utility model includes a top beam body 1, a slider 3 and an adjusting member 4. The top beam body 1 is provided with a guide groove 11 opening downward, and the guide groove 11 extends along the length direction of the top beam body 1. The guide groove 11 is used to install the upper roller 500 of the shower door 400. The number of guide grooves 11 is configured according to the number of shower doors 400. In some scenarios, only one movable shower door 400 is required, and only one guide groove 11 can be set in the top beam body 1. In some scenarios, multiple movable shower doors 400 are required, and multiple guide grooves 11 are set in the top beam body 1 along the width direction at intervals, and each shower door 400 is configured corresponding to a guide groove 11.

[0045] The two sides of the guide groove 11 are groove walls 12, and a gap adjustment cavity 13 is arranged in the groove wall 12 on at least one side. The cavity wall 131 of the gap adjustment cavity 13 can be stretched and deformed toward the guide groove 11 to reduce the shaking gap of the upper roller 500. In order to enable the cavity wall 131 of the gap adjustment cavity 13 to deform, a notch 133 is provided at the bottom of the gap adjustment cavity 13. When the cavity wall 131 is subjected to force and expands, the notch 133 can be adaptively expanded or contracted. The gap adjustment cavity 13 and the notch 133 both extend along the length direction of the top beam body 1. The inner surface of the cavity wall 131 is provided with a guiding inclined surface 132, and the inner surface referred to here refers to the surface of the cavity wall 131 facing the side of the gap adjustment cavity 13. The cavity wall 131 is a part of the groove wall 12, and the outer surface of the cavity wall 131 faces the guide groove 11, and the outer surface of the cavity wall 131 is the wall surface of the groove wall 12 on one side. Therefore, when the cavity wall 131 is expanded, squeezed, and deformed toward the guide groove 11 , the width of the guide groove 11 is reduced so that the wall surface of the groove wall 12 is in contact with the upper roller 500 , thereby reducing the shaking clearance of the upper roller 500 .

[0046] The guiding inclined surface 132 can be inclined upward and inward, or downward and inward. The inward referred to here refers to the middle direction toward the gap adjustment cavity 13.

[0047] The slider 3 is slidably mounted in the gap adjustment cavity 13 , and has a slider slope 31 adapted to the guide slope 132 . The slider slope 31 is parallel to the guide slope 132 .

[0048] When the guide slope 132 is tilted upward and inward, the guide slope 132 is located in the middle and upper part of the gap adjustment cavity 13. In normal state, the slider 3 is located in the middle and lower part of the gap adjustment cavity 13, and the slider slope 31 is located on the side of the slider 3 and tilted upward and inward. When the slider 3 is driven to move upward, the slider slope 31 acts on the guide slope 132, and causes the cavity wall 131 to be expanded, squeezed or deformed toward the guide groove 11.

[0049] When the guide slope 132 is tilted downward and inward, the guide slope 132 is located in the middle and lower part of the gap adjustment cavity 13. In normal state, the slider 3 is located in the middle and upper part of the gap adjustment cavity 13, and the slider slope 31 is located on the side of the slider 3 and tilted downward and inward. When the slider 3 is driven to move downward, the slider slope 31 acts on the guide slope 132, and causes the cavity wall 131 to be expanded, squeezed or deformed toward the guide groove 11.

[0050] The adjusting member 4 is movably connected to the groove wall 12, and is used to drive the slider 3 to move up and down in the gap adjusting cavity 13 to adjust the height of the slider 3 in the gap adjusting cavity 13. The end of the adjusting member 4 is connected to the slider 3. The adjusting member 4 can be a telescopic member, a screw member, etc. The fixed part of the telescopic member is fixedly connected to the groove wall 12, and the telescopic end of the telescopic member is connected to the slider 3, so that the slider 3 can be driven to move up and down in the gap adjusting cavity 13. One installation method of the screw member is: the screw member is threadedly connected to the groove wall 12, and the end of the screw member is pivotally connected to the slider 3, and the slider 3 can be driven to move up and down in the gap adjusting cavity 13 by rotating the screw member. Another installation method of the screw member is: the screw member is pivotally connected to the groove wall 12 and axially limited, and the end of the screw member is threadedly connected to the slider 3, and the slider 3 can also be driven to move up and down in the gap adjusting cavity 13 by rotating the screw member.

[0051] When installing the shower door 400, the slider 3 is placed in the initial state by adjusting the member 4. At this time, the slider slope 31 is separated from or slightly in contact with the guide slope 132, and the cavity wall 131 is not stretched or deformed, so that the upper roller 500 can be installed in the guide groove 11. After the shower door 400 is installed, the adjusting member 4 is operated to move the slider 3 toward the guide slope 132. The slider slope 31 acts on the guide slope 132 to stretch the cavity wall 131, so as to reduce the shaking clearance of the upper roller 500.

[0052] In summary, the shower door top beam 100 provided by the utility model adjusts the height of the slider 3 in the gap adjustment cavity 13 through the adjusting component 4, and the cavity wall 131 of the gap adjustment cavity 13 is stretched open by the slider 3, so that the cavity wall 131 is stretched and deformed toward the guide groove 11 side to reduce the shaking gap of the upper roller 500, which is beneficial to reduce the shaking amplitude of the shower door 400, reduces noise, and is beneficial to improving the user experience.

[0053] As required, a plurality of sliders 3 may be arranged in the gap adjustment cavity 13 at intervals along the length direction, and each slider 3 is driven by a set of adjustment components 4 .

[0054] As required, the slider 3 is in the shape of an elongated strip and extends along the length direction of the gap adjustment cavity 13 . An appropriate number of adjustment components 4 can be selected to drive the elongated slider 3 .

[0055] In one embodiment, if Figure 2-4 As shown, the top beam body 1 is provided with a plurality of guide grooves 11 , and the plurality of guide grooves 11 are arranged at intervals along the width direction of the top beam body 1 .

[0056] The groove wall 12 between any two adjacent guide grooves 11 is provided with at least one gap adjustment cavity 13 and at least one adjustment member 4 . A slider 3 is installed in each gap adjustment cavity 13 , and each slider 3 is connected to a corresponding adjustment member 4 .

[0057] In this embodiment, the top beam body 1 is provided with a plurality of guide grooves 11 arranged at intervals along the width direction to adapt to a plurality of shower doors 400. A gap adjustment cavity 13 is provided on the groove wall 12 between every two adjacent guide grooves 11, and a slider 3 is disposed in each gap adjustment cavity 13. A plurality of adjustment members 4 are provided on the groove wall 12 between every two adjacent guide grooves 11, and the adjustment members 4 are connected to the corresponding sliders 3. When the sliders 3 are driven to move and open the cavity walls 131, the cavity walls 131 on both sides of the gap adjustment cavity 13 are opened, and the shaking gaps of the upper rollers 500 in the two adjacent guide grooves 11 are adjusted at one time.

[0058] In one embodiment, if Figure 4-5 As shown, in the direction from bottom to top, the guide slope 132 and the slider slope 31 extend obliquely toward the middle direction of the gap adjustment cavity 13 respectively.

[0059] In this embodiment, the guide slope 132 and the slider slope 31 are arranged to be inclined upward and inward. The guide slope 132 is located in the middle and upper part of the gap adjustment cavity 13, and the slider slope 31 is located on the side of the slider 3 and is inclined upward and inward. In the initial state, the slider 3 is at the widest part of the guide slope 132 or below the guide slope 132. When the slider 3 is driven to move upward, the slider slope 31 acts on the guide slope 132, and causes the cavity wall 131 to be stretched, squeezed or deformed toward the guide groove 11.

[0060] In one embodiment, if Figure 3-4As shown, a support frame 134 for supporting the slider 3 is provided at the bottom of the gap adjustment chamber 13. The support frame 134 is provided on the bottom plate of the gap adjustment chamber 13 and is located around the notch 133. The support frame 134 is used to support the slider 3 in the initial state and reduce the distance between the slider 3 and the guide inclined surface 132 so that when the adjustment is made by the adjustment member 4, the slider inclined surface 31 acts on the guide inclined surface 132 more quickly, thereby shortening the adjustment stroke and time.

[0061] In one embodiment, if Figure 2-3 As shown, the bottom of the groove wall 12 is connected with a baffle 5 for shielding the notch 133. The baffle 5 can be connected to the bottom of the groove wall 12 by a buckle or the like to shield the notch 133, play a decorative role, and also prevent splashing water from entering the gap adjustment cavity 13.

[0062] In one embodiment, if Figure 1-3 As shown, the shower door top beam 100 includes a U-shaped top beam cover plate 2, and the top beam cover plate 2 is detachably connected to the top beam body 1. The top beam cover plate 2 wraps the top beam body 1 to play a decorative role.

[0063] In one embodiment, if Figure 3-7 As shown, the adjusting member 4 includes a vertically arranged adjusting screw 41 , the adjusting screw 41 is pivotally connected to the slot wall 12 , and a limiting structure for limiting the axial movement of the adjusting screw 41 is provided between the adjusting screw 41 and the slot wall 12 .

A limiting structure is provided between the adjusting screw 41 and the groove wall 12 to limit the axial movement of the adjusting screw 41. When the adjusting screw 41 is rotated, the adjusting screw 41 only rotates without moving up and down, and will not interfere with the surrounding structure.

[0066] The slider 3 is provided with an internal thread hole 32 , and the internal thread hole 32 can be rotated to be a through hole or a blind hole. The screw tail end 411 of the adjusting screw 41 is connected to the internal thread hole 32 .

[0067] In the initial state, the slider 3 is at the widest part of the guide slope 132, and the slider slope 31 contacts the guide slope 132 and has a certain friction force to prevent the slider 3 from rotating. When the adjusting screw 41 is turned, the adjusting screw 41 only rotates without axial movement. Under the action of the thread, the slider 3 moves upward along the adjusting screw 41, from the widest part to the narrowest part of the guide slope 132, thereby expanding the cavity wall 131. When the adjusting screw 41 is turned in the opposite direction, the slider 3 moves down to the initial position.

[0068] As required, a vertical guide post can be provided in the gap adjustment cavity 13, and the slider 3 is loosely fitted on the guide post, and the guide post limits the rotation of the slider 3. In this case, the slider 3 is no longer prevented from rotating by the friction between the slider slope 31 and the guide slope 132. In the initial state, the slider 3 can be located below the guide slope 132, and the slider slope 31 and the guide slope 132 can be separated.

[0069] As required, the limiting structure can be selected to set a limiting groove in the hole of the groove wall 12, and the rotating member is loosely fitted in the limiting groove.
