Description

Technical Field

[0001] This utility model relates to the field of shower room door structure technology, and in particular to an anti-derailment structure for shower room doors. Background Technology

[0002] Sliding shower doors are widely used in modern bathroom designs due to their space-saving opening mechanism and sleek, modern appearance. Their core working principle involves a pulley system installed at the top of the door, suspended within an upper track, allowing the door to slide open and close. However, traditional shower door pulley systems typically use a simple T-shaped or inverted C-shaped fit with the upper track, and generally lack a reliable anti-derailment structure. This results in a large play between the track and the pulleys. When the door is subjected to rapid pushing or pulling, accidental impact, or slight settlement / vibration of the building structure, the pulleys are prone to "jumping" out of the track due to instantaneous vertical displacement, causing derailment. This can not only lead to serious safety accidents such as the glass door falling and shattering, but also render the door unusable. Therefore, there is an urgent need for an anti-derailment structure for shower doors to effectively reduce the risk of pulley derailment and improve the safety of shower doors during use. Utility Model Content

[0003] The purpose of this invention is to provide an anti-derailment structure for shower doors, solving the problem that the pulleys of traditional shower doors are prone to derailment.

[0004] The present invention provides the following technical solution: an anti-derailment structure for a shower door, comprising a door, an upper rail, and a pulley mechanism and an anti-derailment mechanism disposed between the door and the upper rail. The upper rail has an inner cavity along its length, and the cross-section of the upper rail is a downward-opening "C" shape. The lower side wall of the inner cavity has a flange disposed along the length of the upper rail. The pulley mechanism includes a concave pulley corresponding to the flange. The anti-derailment mechanism includes an anti-derailment block and a limiting protrusion. The concave pulley and the anti-derailment block are respectively disposed on both sides of the door. The limiting protrusion is disposed on the upper side of the inner cavity along the length of the upper rail. When the concave pulley is engaged and rolls on the flange, the anti-derailment block can abut against the limiting protrusion to prevent the concave pulley from disengaging from the flange along the height direction.

[0005] As described above, an anti-derailment structure for a shower room door is provided, wherein the doors are arranged in pairs, the concave pulleys are respectively provided on the opposite sides of each door, and the anti-derailment blocks are respectively provided on the opposite sides of each door, such that the paired doors are spaced apart on both sides of the adjacent anti-derailment blocks, and the adjacent anti-derailment blocks can abut against the limiting protrusion.

[0006] As described above, the anti-derailment structure for a shower door includes a pulley mechanism that further comprises a pulley frame and a connector. At least two concave pulleys are movably provided on one side of the pulley frame. One end of the connector passes through the door and is connected to the pulley frame. The anti-derailment block is provided on the end of the connector away from the pulley frame.

[0007] As described above, in an anti-derailment structure for a shower door, the anti-derailment block is platform-shaped, and a nesting opening is provided on the side of the anti-derailment block near the connector. A nesting plate is provided on the side of the connector near the anti-derailment block, and the nesting opening can be fitted onto the nesting plate, so that the anti-derailment block is connected to the connector.

[0008] As described above, in an anti-derailment structure for a shower door, the nested disc has multiple anti-slip strips on its periphery.

[0009] As described above, in a shower door anti-derailment structure, the connector is provided with a plug sleeve on the side near the pulley frame, the pulley frame is provided with a fixed shaft on the side near the connector, the plug sleeve is plugged into the door and sleeved on the fixed shaft, and the plug sleeve and the fixed shaft are eccentrically arranged.

[0010] As described above, in an anti-derailment structure for a shower door, the pulley mechanism further includes screws that pass through the nesting disc and are axially fixed to the fixed shaft to lock the connector and the pulley frame on both sides of the door.

[0011] As described above, in an anti-derailment structure for a shower door, the limiting protrusion is arched on the side near the anti-derailment block.

[0012] Compared with the prior art, the present invention has the following advantages: This utility model discloses an anti-derailment structure for shower doors. It employs a pulley mechanism and an anti-derailment mechanism between the door and the upper rail to prevent the door from derailing while moving along the upper rail. The pulley mechanism includes a concave pulley on one side of the door, which engages with a flange on the lower side of the inner wall of the upper rail, enabling the door to slide open and close. The anti-derailment mechanism includes a limiting protrusion on the upper side of the inner cavity and an anti-derailment block on the other side of the door. A gap exists between the upper side of the anti-derailment block and the lower side of the limiting protrusion. The width of this gap can be set to be less than the height required for the concave pulley to completely detach from the flange. Therefore, when the door moves, the limiting protrusion continuously restricts the anti-derailment block, effectively preventing the concave pulley from completely detaching from the flange and avoiding the risk of the door derailing during opening and closing, making the shower door safer and more reliable.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Please refer to the appendix Figure 1 To be continued Figure 4This embodiment provides an anti-derailment structure for a shower door, including a door 1, an upper rail 2, and a pulley mechanism 3 and an anti-derailment mechanism 4 disposed between the door 1 and the upper rail 2. The upper rail 2 has an inner cavity 21 along its length, and the cross-section of the upper rail 2 is a downward-opening "C" shape. The lower side wall of the inner cavity 21 has a flange 22 disposed along the length of the upper rail 2. The pulley mechanism 3 includes a concave pulley 31 disposed corresponding to the flange 22. The anti-derailment mechanism 4 includes an anti-derailment block 41 and a limiting protrusion 42 disposed correspondingly. The concave pulley 31 and the anti-derailment block 41 are respectively disposed on both sides of the door 1. The limiting protrusion 42 is disposed on the upper side of the inner cavity 21 along the length of the upper rail 2. When the concave pulley 31 is engaged and rolls on the flange 22, the anti-derailment block 41 can abut against the limiting protrusion 42 to prevent the concave pulley 31 from disengaging from the flange 22 along the height direction. The anti-derailment structure for a shower door in this embodiment employs a pulley mechanism 3 and an anti-derailment mechanism 4 in cooperation between the door 1 and the upper rail 2 to achieve an anti-derailment effect when the door 1 moves along the upper rail 2. The pulley mechanism 3 includes a concave pulley 31 located on one side of the door 1. The concave pulley 31 engages with the flange 22 on the lower side of the inner cavity 21 of the upper rail 2, enabling the sliding opening and closing of the door 1. The anti-derailment mechanism 4 includes a limiting protrusion 42 on the upper side of the inner cavity 21 and an anti-derailment block 41 on the other side of the door 1. There is a certain gap between the upper side of the anti-derailment block 41 and the lower side of the limiting protrusion 42. The width of this gap can be set to be less than the height required for the concave pulley 31 to completely detach from the concave flange 22. Therefore, when the door 1 moves, the limiting protrusion 42 continuously restricts the anti-derailment block 41, effectively preventing the concave pulley 31 from completely detaching from the flange 22, avoiding the risk of the door 1 derailing during opening and closing, and making the use of the shower door safer and more reliable.

[0020] The door 1 is arranged in pairs, with concave pulleys 31 respectively located on opposite sides of each door 1, and anti-detachment blocks 41 respectively located on opposite sides of each door 1, so that the paired door 1 is spaced apart on both sides of the adjacent anti-detachment blocks 41, and the adjacent anti-detachment blocks 41 can abut against the limiting protrusions 42. The paired door 1 can be a double door, and each door can be alternately opened and closed along the length of the upper rail 2.

[0021] The pulley mechanism 3 also includes a corresponding pulley frame 32 and a connecting member 33. At least two concave pulleys 31 are movably provided on one side of the pulley frame 32. One end of the connecting member 33 passes through the door 1 and is connected to the pulley frame 32. An anti-detachment block 41 covers the end of the connecting member 33 away from the pulley frame 32. The multiple pulleys of the pulley frame 32 make the sliding opening and closing of the door more stable.

[0022] The anti-detachment block 41 is platform-shaped, and a nesting opening 411 is provided on the side of the anti-detachment block 41 near the connector 33. A nesting plate 331 is provided on the side of the connector 33 near the anti-detachment block 41. The nesting opening 411 can be fitted onto the nesting plate 331, so that the anti-detachment block 41 is connected to the connector 33. Preferably, multiple anti-slip strips 3311 are provided on the periphery of the nesting plate 331 to make the connection between the anti-detachment block 41 and the nesting plate 331 more secure.

[0023] The connector 33 has a plug-in sleeve 332 on the side near the pulley frame 32, and the pulley frame 32 has a fixed shaft 321 on the side near the connector 33. The plug-in sleeve 332 is plugged into the door 1 and sleeved on the fixed shaft 321, and the plug-in sleeve 332 and the fixed shaft 321 are eccentrically arranged. The pulley mechanism 3 also includes a screw 34, which passes through the nesting disc 331 and is axially fixed to the fixed shaft 321 to lock the connector 33 and the pulley frame 32 on both sides of the door 1. The eccentric arrangement of the plug-in sleeve 332 and the fixed shaft 321 makes it difficult for the screw 34 to come out of the fixed shaft 321.

[0024] Preferably, the side of the limiting protrusion 42 closest to the anti-detachment block 41 is arched, which can further reduce the gap between the limiting protrusion 42 and the anti-detachment block 41.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
