[0007] Furthermore, the bearing surface is arranged horizontally.

[0008] Furthermore, a limiting member is installed on the upper end of the guide carrier plate, so that one end of the guide carrier plate forms a limiting cavity with an opening, and the limiting cavity is used to limit the up and down movement of the roller.

[0009] Furthermore, it also includes a lock assembly installed on the door leaf.

[0010] Furthermore, the lock assembly is installed on a side of the roller away from the guide carrier plate, and a slot for cooperating with the lock assembly is provided on the door frame or the guide carrier plate.

[0011] Furthermore, the locking assembly includes a claw for cooperating with the slot, a positioning base and a driver, one end of the claw is rotatably mounted on the positioning base, and the driver is used to drive the claw to rotate along the positioning base.

[0012] Furthermore, a first spring for connecting with the claw is provided in the middle of the positioning base.

[0013] Furthermore, the clamping claw is provided with an adjusting screw for abutting against the positioning base.

[0014] Furthermore, the driver includes a driving motor, a driving shaft and a fixing seat. The driving motor drives the driving shaft to move up and down along the fixing seat through a cam structure, and the upper end of the driving shaft abuts against the claw.

[0015] Furthermore, the cam structure includes a cam member mounted on the drive motor and a pulley mounted on the lower end of the drive shaft. The pulley can rotate along the cam member, and a second spring is provided between the pulley and the fixed seat.

[0016] The utility model provides a roller on the door leaf that can roll along the guide carrier plate, so that the door leaf can be corrected and reset when closing, avoiding the door leaf being in a skewed state in the closed state, thereby ensuring that the door leaf can complete the closing and locking action.

DETAILED DESCRIPTION

[0024] The present invention will be described in further detail below with reference to the accompanying drawings and specific implementations.

[0025] In this embodiment, refer to Figures 1-6 The invention specifically implements an auxiliary door closing mechanism, which includes a guide carrier plate 1 fixedly mounted on a door frame 18 and a roller 2 rotatably mounted on a door leaf 19. The upper end of the guide carrier plate 1 is provided with a bearing surface 101 for supporting the roller 2, and one end of the bearing surface 101 is provided with a downwardly inclined guide portion 102.

[0026] Furthermore, a limiting member 3 is installed at the upper end of the guide carrier plate 1, so that one end of the guide carrier plate 1 forms a limiting cavity 4 with an opening. The limiting cavity 4 is used to limit the up and down movement of the roller 2, thereby ensuring the stability and reliability of the door leaf 19 when closing.

[0027] Furthermore, the carrying surface 101 is arranged horizontally.

[0028] Furthermore, a latch assembly is installed within the door leaf 19. The latch assembly is mounted on the side of the roller 2 away from the guide carrier 1. The guide carrier 1 is provided with a slot 103 for engaging with the latch assembly. The latch assembly includes a claw 5 for engaging with the slot 103, a positioning base 6, and a driver. One end of the claw 5 is rotatably mounted on the positioning base 6, and the driver is used to drive the claw 5 to rotate along the positioning base 6. During use, the driver drives the claw 5 to flip up and down, thereby achieving engagement and separation between the claw 5 and the slot 103.

[0029] A further latching slot 103 may also be provided on the door frame 18 , the purpose of which is to cooperate with the latching claw 5 to lock the door leaf 19 .

[0030] Furthermore, a first spring 7 for connecting with the claw 5 is provided in the middle of the positioning base 6. The first spring 7 is used to provide a pressing force between the claw 5 and the card slot 103 to ensure the locking firmness of the door leaf 19.

[0031] Furthermore, the claw 5 is provided with an adjusting screw 8 for abutting against the positioning base 6. In actual use, the adjusting screw 8 can adjust the inclination angle of the claw 5, so that the claw 5 can smoothly engage with the slot 103 to reduce the probability of jamming.

[0032] Furthermore, the driver includes a drive motor 9, a drive shaft 10, and a fixed seat 11. The drive motor 9 drives the drive shaft 10 to move up and down along the fixed seat 11 via a cam structure, with the upper end of the drive shaft 10 abutting against the claw 5. The cam structure includes a cam member 12 mounted on the drive motor 9 and a pulley 13 mounted on the lower end of the drive shaft 10. The pulley 13 can rotate along the cam member 12, and a second spring 14 is disposed between the pulley 13 and the fixed seat 11. During use, the drive motor 9 drives the elliptical cam member 12 to rotate, thereby driving the drive shaft 10 to move up and down, so that the drive shaft 10 can push the claw 5 to tilt and rotate, thereby achieving the purpose of driving the claw 5.

[0033] Furthermore, the driver can also be a commonly used air cylinder or electric cylinder on the market, and the purpose of the driver is to push the claw 5 to rotate up and down.

[0034] The present invention provides a roller 2 on the door leaf 19 that can roll along the guide carrier plate 1, so that the door leaf 19 can be corrected and reset when closing, avoiding the door leaf 19 from being in a skewed state in the closed state, thereby ensuring that the door leaf 19 can complete the closing and locking action.
