Description

Technical Field

[0001] This utility model relates to the field of door deformation prevention technology, specifically a linkage door deformation prevention support device. Background Technology

[0002] A door anti-deformation support device is an auxiliary device used to prevent structural deformation of the door due to external forces, its own weight, or long-term use. It is commonly found in door sets, rail transit platform doors, and sliding doors. Existing support methods include structurally reinforced supports, elastic supports, dynamic anti-sway supports, and linkage control supports. A common support method involves installing support wheels at the bottom of the door. The support wheels are in contact with the ground. When the door moves, they cause the support wheels to roll along the ground, supporting the upper part of the door and preventing it from deforming due to gravity.

[0003] Screws or welded joints of the fixing bracket may gradually loosen due to vibration, leading to bracket displacement or a decrease in load-bearing capacity. Regular inspection and adjustment are necessary, but the high frequency of these checks can result in untimely or missed inspections, thus affecting the door's support and anti-deformation effect. Therefore, a linkage door anti-deformation support device is required to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant support device for a linkage door, addressing the problem mentioned in the background art where the screws or welds of the fixing bracket may gradually loosen due to vibration, leading to bracket displacement or a decrease in load-bearing capacity. This necessitates regular inspection and adjustment, but the high frequency of these checks can result in untimely or missed inspections, thus affecting the door's deformation-resistant support effect. To solve the above technical problems, this utility model achieves this through the following technical solution: This utility model is a linkage door anti-deformation support device, comprising: The linkage door leaf includes a door body, a bracket, and wheels. The bracket is fixed to both sides of the lower end of the door body, and the wheels are rotatably connected to the lower end of the bracket. The reinforcement component includes a connecting pipe, a connecting block, a second through hole, and a connecting strip. The connecting pipe is fixed to the lower side of the bracket. The two ends of the connecting block are respectively inserted into the two connecting pipes. The second through hole is opened in the middle of the connecting block. The connecting strip is inserted into the second through hole and fixed to the middle of the lower end of the door. The reinforcement component also includes a first through hole, which is located at the lower end of the side of the bracket and communicates with the connecting pipe. The reinforcement assembly also includes a reinforcing plate and a wear-resistant pad. The reinforcing plate is fixed to both ends of the connecting block, and the wear-resistant pad is sandwiched between the connecting strip and the door body.

[0005] Furthermore, there are four sets of brackets and wheels, which are symmetrically connected to both sides of the door.

[0006] Furthermore, there are two connecting blocks located at the lower end of the door body, with connecting pipes at both ends inserted into the first through hole.

[0007] Furthermore, it also includes a connecting component, which includes a third through hole and connecting rods. The third through hole is opened in the middle of the bracket, and there are two connecting rods, which are respectively inserted into the third through holes on the two brackets on the same side of the door.

[0008] Furthermore, the connecting assembly also includes fastening nuts, which are screwed onto both ends of the connecting rod and abut against the side of the bracket.

[0009] This utility model has the following beneficial effects: This utility model, through the setting of a reinforcing component, fits the connecting block through the second through hole onto both ends of the connecting strip, then places the wear-resistant pad on the connecting strip, and fixes the connecting strip to the lower end of the door body with screws. Subsequently, the bracket is fixed to both sides of the door body, so that both ends of the connecting block are inserted into the connecting tube. This setting reinforces the bracket and reduces the probability of the bracket coming loose due to loose screws at the connection point.

[0010] Based on the aforementioned beneficial effects, by using the connecting component, the connecting rod is inserted into the third through hole of the bracket on the same side, and the fastening nut is tightened. This design can connect the brackets on both sides, reducing the probability of the screws loosening. Attached Figure Description

The bracket 11 is fixed to both sides of the lower end of the door body 10, and the wheels 12 are rotatably connected to the lower end of the bracket 11. There are four sets of brackets 11 and wheels 12, which are symmetrically connected to both sides of the door body 10. The door 10 is used to isolate the space on both sides, the bracket 11 serves as a connection, a tripod is selected for its high strength, and the wheels 12 provide support while reducing the frictional resistance when the door 10 moves.

[0017] The reinforcement component includes a connecting pipe 21, a connecting block 22, a second through hole 24, and a connecting strip 25. The connecting pipe 21 is fixed to the lower side of the bracket 11. The two ends of the connecting block 22 are respectively inserted into the two connecting pipes 21. The second through hole 24 is opened in the middle of the connecting block 22. The connecting strip 25 is inserted into the second through hole 24 and fixed to the middle of the lower end of the door body 10. The reinforcement component also includes a first through hole 20, which is located at the lower side of the bracket 11 and communicates with the connecting pipe 21. The reinforcement components also include a reinforcing plate 23 and a wear-resistant pad 26. The reinforcing plate 23 is fixed to both ends of the connecting block 22, and the wear-resistant pad 26 is sandwiched between the connecting strip 25 and the door body 10. There are two connecting blocks 22, located at the lower end of the door body 10, with both ends passing through the connecting pipe 21 and inserted into the first through hole 20; The first through hole 20 serves as a connection, the connecting pipe 21 serves as a connection, the connecting block 22 serves as a connection, the reinforcing plate 23 can improve the strength of the connecting block 22, the second through hole 24 facilitates the connection of the two connecting blocks 22 by the connecting strip 25, and the wear-resistant gasket 26 serves as a connection and can increase the firmness of the screw connection.

[0018] Working principle: Connecting blocks 22 are fitted onto both ends of connecting strip 25 through the second through hole 24. Wear-resistant pads 26 are placed on connecting strip 25, and connecting strip 25 is fixed to the lower end of door body 10 with screws. Then, bracket 11 is fixed to both sides of door body 10, so that both ends of connecting blocks 22 are inserted into connecting tube 21. When door body 10 moves, it drives bracket 11 to move, which in turn drives wheel 12 to roll in contact with the ground. Due to gravity, door body 10 falls and presses wheel 12 on bracket 11 firmly onto the ground. Connecting blocks 22 at both ends of connecting strip 25 provide support and reinforcement for bracket 11.

[0019] This step reinforces the bracket 11, reducing the probability of the bracket 11 coming loose due to loose screws at the connection.

The connecting assembly also includes fastening nuts 32, which are screwed onto both ends of the connecting rod 31 and abut against the side of the bracket 11; The third through hole 30 and the connecting rod 31 serve to connect them, and the fastening nut 32 is used to fix the connecting rod 31 to prevent it from falling off.

[0021] Working principle: After installing the door body 10, bracket 11, wheel 12 and reinforcement components, insert the connecting rod 31 into the third through hole 30 of the bracket 11 on the same side. When tightening the fastening nut 32, the door body 10 is moved, which drives the bracket 11 and wheel 12 to move at the same time, and the connecting rod 31 also moves at the same time. The connecting rod 31 connects the two brackets 11 together and plays a restraining role.

[0022] This step connects the brackets 11 on both sides, reducing the probability of screws becoming loose.
