The excellent slide rail mechanism design can ensure the speed, smoothness and stability of the sliding door when it is opened;

[0003] Due to the need for installation, a certain amount of clearance is usually reserved inside the door frame so that the door frame can be inserted into the door frame, but this also increases the possibility of the door frame derailing during use. In the prior art, a derailment-proof fast door with announcement number CN219061383U is used. While achieving the function of the sliding door, under the action of gravity and the limiting effect of the sliding groove, the possibility of the roller component derailing is prevented;

[0004] However, when the sliding door is opened and closed, there is still a gap between the roller component and the door frame, and the roller component still moves up and down, which may cause the sliding door to derail due to position deviation. In addition, when the sliding door is opened, it is easy to shake when it collides with the door frame, which may cause derailment.

[0005] Therefore, the present application provides an anti-derailment fast door to meet the demand. Utility Model Content

[0006] In view of this, the purpose of the present application is to provide a kind of anti-derail fast door, so that roller is pressed against door frame, pulley is made to slide along door frame wall surface, the situation that pulley is displaced and derailment occurs is avoided, and door frame is limited by stopper at the same time, the stability of door frame when opening and closing is further improved, and good anti-derail effect is achieved.

[0014] Preferably, a clamp block made of rubber is fixedly connected to the vertical portion of the door frame, and the clamp block is arranged on one side of the limiting member.

[0015] Preferably, a buffer pad is attached to the end of the limiting member.

[0016] Compared with the prior art, this application has at least the following beneficial effects:

[0017] In the above scheme, a worm, a bracket, a pulley and a worm wheel are arranged, the worm drives the worm wheel to rotate, and the worm wheel drives the bracket to swing, pressing the pulley against the inner wall of the door frame, and utilizing the self-locking characteristics of the worm and the worm wheel to keep the pulley in contact with the inner wall of the door frame, thereby reducing the space for the door body to slide up and down as a whole, thereby achieving a good anti-derailment effect.

[0018] In the above scheme, by providing a limit piece and a limit strip, and at the same time, the limit piece is clamped at the end corner of the door body. When the door body approaches the door frame during the pushing and pulling process, the limit piece is first clamped in the vertical part of the door frame, and the door body is guided and limited by the limit piece. The limit strip can limit the vertical part of the door body. The limit strip strengthens the structural strength of the vertical part of the door body, and can effectively overcome the derailment caused by the deformation and bending of the door body under force. The impact force is absorbed by the contraction of the spring to reduce the impact force of the door body on the door frame, control the shaking amplitude of the door body, improve the stability of the door opening and closing, and reduce derailment.

[0027] like Figure 1 , Figure 2 and Figure 3 A kind of anti-derailment fast door shown, an embodiment of the present application provides, including a base plate 1, a door frame 2 is arranged on the top of the base plate 1, a sliding groove is provided on the inner top of the door frame 2, a door body 3 is provided with an inner sliding of the door frame 2, a limit member 4 is provided at the end angle position of the door body 3, the limit member 4 is clamped on the vertical part of the door frame 2, a mounting groove is provided on the top of the door body 3, a bracket 5 is hinged in the top mounting groove of the door body 3, and a pulley 501 is connected to the end of the bracket 5;

[0028] The door body 3 is embedded in the top sliding groove inside the door frame 2. Through the rotatable bracket 5, the pulley 501 can abut against the wall surface of the sliding groove inside the door frame 2. The pulley 501 is limited by the sliding groove inside the door frame 2 and has good stability.

[0029] At the same time, the end corners of the door body 3 are clamped with the limiting piece 4. When the door body 3 approaches the door frame 2 during the pushing and pulling process, the limiting piece 4 is first clamped in the vertical part of the door frame 2. The door body 3 is guided and limited by the limiting piece 4 to reduce the space for the sliding door to shake, thereby achieving a good limiting effect.

[0030] In this embodiment, Figure 2-Figure 5 As shown; the end of the bracket 5 is fixedly connected to a worm wheel 502, and the top of the door body 3 is penetrated by a worm 301, and the worm 301 is meshed with the worm wheel 502;

[0031] The worm 301 drives the worm wheel 502 to rotate, and the worm wheel 502 drives the bracket 5 to swing, pressing the pulley 501 to the inner wall of the door frame 2. The self-locking characteristics of the worm 301 and the worm wheel 502 are used to keep the pulley 501 in contact with the inner wall of the door frame 2, so that the space for the door body 3 to slide up and down as a whole is reduced, so as to achieve a good anti-derailment effect;

[0032] Two pulleys 501 are distributed on the top of the door body 3, and the two pulleys 501 are respectively located on both sides of the top surface of the door body 3. The two pulleys 501 can individually adjust the distance between them and the door frame 3 to adapt to the gap between the door frame 2 and the door body 3.

[0033] A vertical downward groove is provided at the edge of the top surface of the door body 3, and an opening is provided on the side wall of the groove, and the stopper 4 is slidably provided in the groove at the top of the door body 3;

[0034] A spring 401 is installed on the side of the limiting member 4;

[0035] When the stopper 4 abuts against the wall of the vertical part of the door frame 2, the door body 3 can still move toward the vertical part of the door frame 2. At this time, the spring 401 is compressed and contracts. The contraction of the spring 401 absorbs the impact force to reduce the impact force of the door body 3 on the door frame 2, control the shaking amplitude of the door body 3, improve the stability of the door body 3 opening and closing, and reduce the derailment.

[0036] At the same time, the stopper 4 is connected to the door body 3 through the groove, and the door body 3 cannot swing back and forth relative to the stopper 4, further ensuring the accuracy of the position of the door body 3 relative to the door frame 2;

[0037] A limiting strip 402 is provided at the bottom of the limiting member 4, and the limiting strip 402 is provided through the vertical part of the door body 3;

[0038] The limiting strip 402 is arranged in the vertical part of the door body 3. When the limiting member 4 is limited by the door frame 2, the limiting strip 402 can limit the vertical part of the door body 3. The limiting strip 402 strengthens the structural strength of the vertical part of the door body 3, and can effectively overcome the derailment caused by the deformation and bending of the door body 3 under stress;

[0039] The door body 3 is embedded in the top inner slide groove of the door frame 2, and the height of the stopper 4 is consistent with the height of the overlapping portion of the door body 3 relative to the door frame 2;

[0040] The pulley 501, the bracket 5 and the stopper 4 are all hidden in the door frame 2, so that the overall lines of the door body 3 are simple and beautiful. At the same time, the pulley 501, the bracket 5 and the stopper 4 are not easily invaded by foreign objects, and the use is more convenient;

[0041] The vertical part of the door frame 2 is fixedly connected with a clamp block 201 made of rubber material, and the clamp block 201 is arranged on one side of the limiting member 4;

[0042] The clamping block 201 is used to limit the position of the limiting member 4. The clamping block 201 made of rubber material is soft and can absorb vibration to achieve a silent effect.

[0043] The end of the limiting member 4 is attached with a buffer pad 403;

[0044] The buffer pad 403 prevents the limiter 4 from colliding head-on with the clamping block 201, thereby achieving a buffering and silencing effect.
