The short strip connecting member 210 is provided to connect the spring sleeve 230 and the carrier 200;

[0026] At the end of the long strip connecting member 240 away from the large beam 300, there is a damping buffer component. The damping buffer component includes a plastic guard block 201. The plastic guard block 201 is arranged inside the carrier 200. At the top end of the outer wall of the plastic guard block 201 and on the side close to the long strip connecting member 240, it is hinged to the end of the long strip connecting member 240 through a pin shaft. The two ends of the pin shaft are rotatably connected to the front and rear sides of the inner wall of the carrier 200. Inside the plastic guard block 201, there are through grooves opened. Inside the through grooves, there is a damper 205 installed. The damping shaft of the damper 205 is arranged towards the direction of the long strip connecting member 240. The damping shaft of the damper 205 abuts against the corresponding position on the right side of the inner wall of the carrier 200. The opened through grooves are for installing the damper 205. The damper 205 is provided to buffer when opening and closing the door panel 100, and improve the service life of the three-stage force hinge;

[0027] On the inner wall of the through groove and outside the damper 205, a damper sleeve slider 206 is provided. The outer walls of the damper 205 are in contact with the inner wall of the damper sleeve slider 206. The damper sleeve slider 206 is provided to stably position the damper 205 in the installation groove. At the same time, it also enables the nylon plastic elastic glue block 202 to adjust the position of the damper 205. An installation groove is opened at the top end of the outer wall of the plastic guard block 201. A nylon plastic elastic glue block 202 is installed on the inner wall of the installation groove. The bottom end of the nylon plastic elastic glue block 202 is in contact with the outer wall of the damper sleeve slider 206 away from the damper 205 through a short rod. The nylon plastic elastic glue block 202 is provided to press tightly against the damper 205 and the damper sleeve slider 206 from the rear end of the plastic guard block 201 through an elastic force, and at the same time, it can also adjust the position of the damper 205 in the installation groove. At the top end of the outer wall of the nylon plastic elastic glue block 202 and close to the damper 205, a hinge seat 203 is integrally fixed. A locking force button 204 is hinged to the inner wall of the hinge seat 203 through a pin. The hinge seat 203 is provided to install the locking force button 204 on the nylon plastic elastic glue block 202 through a pin. At the top end of the outer wall of the plastic guard block 201 and at the corresponding position of the locking force button 204, a plurality of adjustment tooth grooves 207 are opened. The bottom ends of the outer walls of the locking force button 204 are engaged with the inner walls of the adjustment tooth grooves 207. An elastic reset block is fixed to the inner wall of the hinge seat 203 and below the bottom end of the locking force button 204. The top end of the elastic reset block is in contact with the bottom end of the outer wall of the locking force button 204 away from the adjustment tooth groove 207. Specifically, through the elastic reset block, the right end of the locking force button 204 can be moved downward and inserted into the opened adjustment tooth groove 207, so as to fix the positions of the nylon plastic elastic glue block 202 and the plastic guard block 201. When it is necessary to adjust the position of the nylon plastic elastic glue block 202, the operator only needs to press down the locking force button 204 to separate the locking force button 204 from the adjustment tooth groove 207, and then the locking force button 204 can be inserted into the required adjustment tooth groove 207 by using the deformation of the nylon plastic elastic glue block 202. Then, the nylon plastic elastic glue block 202 can adjust the positions of the damper 205 and the damper sleeve slider 206 through the short rod. By adjusting the length of the damper shaft extended by the damper 205, the purpose of adjusting the damping value is achieved, so that the device can reduce the damping value to achieve the purpose of quickly closing the door.

[0028] The use process of the utility model is as follows: first, the personnel can assemble the device according to the above instructions, and then respectively place the pocket 200 and the base 330 on the two door panels 100 that need to be opened and closed. When the personnel open and close the door panels 100, the door panels 100 can be easily reset by the provided spring 231. At the same time, when the door panels 100 are opened and closed, the provided long connecting piece 240 will rotate on the plastic guard block 201, so that the plastic guard block 201 can squeeze the damper 205, so that the oil cylinder on the damper 205 cooperates with the damping shaft to provide damping for opening and closing the door panels 100, thereby achieving the purpose of protecting the three-stage force hinge;

[0029] When the personnel need to adjust the damping size of the damper 205, the personnel can press the locking button 204 to separate the locking button 204 from the adjusting tooth groove 207. When the damping of the damper 205 needs to be increased, it is only necessary to extend the sliding distance between the cylinder part of the damper 205 and the damping shaft, that is, to move the nylon plastic elastic rubber block 202 in a direction away from the damping shaft, so that the damper 205 and the damper sleeve sliding member 206 also move in a direction away from the damping shaft. After the adjustment is completed, the locking button 204 is released, and the hinge seat 203 is used to adjust the damping. The elastic reset block fixed on the inner wall allows the left end of the locking button 204 to rotate upward, so that the right end of the locking button 204 can be engaged with the adjusting tooth groove 207. When the damping of the damper 205 needs to be reduced, the person pulls the locking button 204 toward the damping axis when pressing the locking button 204. In this way, the bottom end of the nylon plastic elastic rubber block 202 will move the damper sleeve sliding member 206 and the damper 205 toward the damping axis through the short axis, thereby reducing the length of the damping shaft extended from the damper 205, reducing the damping size, and facilitating personnel to quickly close the door.

[0030] The above is only a preferred embodiment of the utility model. Any person skilled in the art may modify the utility model by using the above technical solution or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
