Description

Technical Field

[0001] This utility model relates to the field of shower room door technology, specifically to a load-bearing installation structure applied to shower room doors. Background Technology

[0002] A shower room utilizes a corner of the room and uses a fence to clearly delineate the shower area, forming a relatively independent bathing space.

[0003] Referring to the double-track double-wheel shower room sliding door disclosed in announcement number CN201301638Y, it includes a movable sliding door and a pulley mechanism fixed on the movable sliding door. The movable sliding door is installed on the door frame track through the pulley mechanism and can slide on it. The pulley mechanism is provided with an inner pulley and an outer pulley on both sides of the sliding direction of the movable sliding door. The inner pulley and the outer pulley are respectively installed on the sliding plate of the door frame track, so that the movable sliding door of the shower room forms a double-track double-wheel installation structure on the door frame track.

[0004] However, since there are at least two sliding doors, both of which are supported by the upper track (door frame track), large sliding doors are quite heavy. Long-term use can easily cause the upper track to deform and the sliding door to sag, which can lead to jamming or even being unable to be pushed when the sliding door is moved, affecting the normal use of the shower room. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a load-bearing installation structure for shower room doors.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A load-bearing installation structure for a shower room door includes an upper track and at least two adjacent sliding doors. The top of each sliding door is provided with a pulley mechanism, and the sliding door is suspended on the upper track by the pulley mechanism and can slide left and right along the upper track. The characteristic is that the two adjacent sliding doors overlap at least partially, and a load-bearing mechanism is provided below the overlapping portion between the two adjacent sliding doors.

[0008] The load-bearing mechanism includes load-bearing wheel modules. The bottom of each sliding door is supported by at least one load-bearing wheel module. Each load-bearing wheel module includes at least one rotatable support roller. The bottom of the sliding door is provided with a lower guide groove extending from left to right. The support roller extends into the lower guide groove, and the upper part of the circumferential wheel surface of the support roller is supported on the groove surface of the lower guide groove.

[0009] In this utility model, the load-bearing mechanism includes a load-bearing base, and the supporting rollers of the same load-bearing mechanism are rotatably mounted on the load-bearing base.

[0010] In this utility model, the load-bearing base is provided with a fixing connection hole for cooperating with fixing bolts.

[0011] In this utility model, the load-bearing base is integrally formed with a roller mounting arm, and the supporting roller is rotatably mounted on the roller mounting arm via a load-bearing wheel axle.

[0012] In this utility model, the load-bearing installation structure also includes a lower support rod located below the upper track, and the load-bearing base is connected to the lower support rod.

[0013] In this utility model, the load-bearing base is provided with a connecting hook, which is hooked onto the lower support rod.

[0014] In this utility model, the sliding door includes a movable frame and a door panel. The movable frame includes a lower movable beam disposed at the bottom end of the door panel. The bottom of the lower movable beam is provided with a movable groove, and the lower guide groove is disposed in the movable groove.

[0015] In this invention, the movable frame further includes a lower rail installed in the movable groove, and the lower guide groove is formed on the bottom of the lower rail.

[0016] In this utility model, the movable frame further includes two movable columns respectively disposed at the left and right ends of the door panel and an upper movable beam disposed at the top of the door panel. The movable columns and the upper movable beam are connected by an upper connecting member, and the pulley mechanism is mounted on the upper connecting member. The lower track is connected to the movable columns by a lower connecting member.

[0017] In this utility model, the lower guide groove includes a guide cavity with an inverted V-shaped cross-section. The guide cavity includes a concave arc groove surface at the top and inclined groove surfaces at the front and rear ends of the concave arc groove surface. The concave arc groove surface is a concave arc surface with an upward arc in the middle. The upper end of the inclined groove surface is connected to the concave arc groove surface, and the lower end extends downward in a direction away from the other inclined groove surface.

[0018] The beneficial effects of this utility model are as follows: A load-bearing mechanism is provided below the overlapping portion between two adjacent sliding doors. This mechanism utilizes support rollers to support the sliding door on the groove surface of the lower guide groove. This allows the support rollers to provide support for the sliding door, achieving the goal of simultaneously supporting the sliding door with the support rollers and pulley mechanism. This reduces the weight of the pulley mechanism acting on the upper track, reduces the probability of upper track deformation, and ensures the stability and smoothness of the sliding door's movement. Furthermore, the guide cavity of the lower guide groove has an inverted V-shaped cross-section, ensuring that the circumferential surface of the support rollers corresponds directly below the concave arc groove surface of the guide cavity. This allows the support rollers to not only support the sliding door but also provide lateral guidance to the lower end of the sliding door, preventing the sliding door from wobbling back and forth.

[0040] In this embodiment, the movable column 22 and the upper movable beam 23 are connected by an upper connecting member 27. The upper movable beam 23 has an upper beam slot 231 extending from left to right, and the movable column 22 has a column slot 221 extending from top to bottom. The upper connecting member 27 is L-shaped. The upper horizontal end 271 of the upper connecting member 27 is inserted into the upper beam slot 231 and is bolted to the upper movable beam 23. The upper vertical end 272 of the upper connecting member 27 is inserted into the column slot 221 and is bolted to the movable column 22. The pulley mechanism 3 is bolted to the upper connecting member 27.

[0041] In this embodiment, the lower rail 25 and the movable column 22 are connected by a lower connector 28. The lower rail 25 is provided with a lower rail slot 251. The lower connector 28 is L-shaped, with its lower horizontal end 281 inserted into the lower rail slot 251 and bolted to the lower rail 25.
