Detailed Description

For a more intuitive and complete understanding of the technical solution of the present invention, the following non-limiting characteristic description is now performed by combining the drawings of the present invention:

the first embodiment is as follows: as shown in fig. 1-8, a two buffering stopper of floating gate, including base 1, be equipped with main buffer gear in the base 1, main buffer gear is connected with and draws slide 2, draw slide 2 to slide and set up on base 1, and draw and be equipped with towing pintle 3 on slide 2, main buffer gear includes a attenuator 4, the one end of base 1 is equipped with supplementary bolster, supplementary bolster is compression spring 5, compression spring 5's one end is pressed on the one end inner wall in the holding chamber that has in base 1, the other end pushes up the cylinder body tip at attenuator 4.

In order to facilitate the installation of the compression spring 5, a sleeve 6 is arranged in one end of the accommodating cavity 1.3 of the base 1, and the compression spring 5 penetrates through the sleeve 6. The damper 4 is also mounted in the receiving chamber 1.3.

The main buffering mechanism further comprises a tension spring 7, one end, far away from the auxiliary buffering piece, of the damper 4 is connected with the traction sliding seat 2 through a connecting head 8, one end, far away from the auxiliary buffering piece, of the tension spring 7 is connected with the traction sliding seat 2 through a pin, the tension spring 7 is arranged in parallel with the damper 4, and the tension spring 7 is located above the damper 4. The lower end of the base 1 is provided with a sliding groove 9 which is transversely arranged, the traction sliding seat 2 is arranged on the sliding groove 9 in a sliding mode, a guide sliding groove 10 which is matched with the traction sliding seat 2 is arranged in the base 1, and the end portion of the guide sliding groove 10 is provided with an upward chute 101. Specifically, the traction sliding seat 2 is provided with a rear guide post 14 and a front guide post 15 which are in sliding fit with the guide chute 10, the end of the guide chute 10 is provided with an upward chute 101 for the front guide post 15 to slide in, and the chute 101 is used for the traction sliding seat 2 to turn over and stay. A groove 11 is formed between the lower end of the traction sliding seat 2 and the lower end of the unhook, and a torsion spring 12 is arranged between the traction sliding seat 2 and the unhook.

The base 1 is composed of a first base 1.1 and a second base 1.2, a protective cover 13 covers the base 1, and the sleeve 6 is arranged on the first base 1.1. Of course, the base 1 can also be designed as a one-piece structure during production. As shown in fig. 8, the base 1 is mounted on a rail 18.

When the drawing sliding seat 2 is at the initial position as shown in fig. 4, the moving door 16 is controlled and limited by the stop boss 21 and the towing hook 3 on the drawing sliding seat 2 along with the push-pull seat 17 fixed thereon, when an external force larger than the tension spring 7 acts on the moving door 16, and the moving door 16 is pushed to be separated from the control of the double buffer limiter of the moving door, the push-pull seat 17 on the moving door drags the drawing sliding seat 2 to move towards the front end of the guide sliding chute 10 in the base 1 through the towing hook 3, and after the situation of the midway advancing is continued as shown in fig. 5, the front guide post 15 on the drawing sliding seat 2 slides into the inclined groove 101 of the guide sliding chute 10, the drawing sliding seat 2 rotates around the rear guide post 14, the towing hook 3 is separated from the push-pull seat 17 along with the rotation of the drawing sliding seat 2, the drawing sliding seat 2 stops at the front end of the guide sliding chute 10 under the action of the tension spring 7 to wait for the next return of the moving door 16, and, if the external force applied to the sliding door 16 is large enough, the sliding door 16 will quickly impact the other end of the door, the double buffer stop (as shown in fig. 7) installed at the other end of the guide rail 18 will meet the impact of the sliding door 16, when the push-pull seat 17 hits the stop boss 21 on the traction sliding seat 2, the traction sliding seat 2 will rotate and slide backwards with the rear guide post 14 on the traction sliding seat as the rotating shaft, the front guide post 15 will also return to the guide chute 10, at the moment of the impact, the impact kinetic energy will be different according to the mass and speed of the sliding door 16, the impact force transmitted to the compression spring 5 through the damper 4 will be different, and at this time, one of the following three conditions will occur:

firstly, the method comprises the following steps: the impact force is small, the impact force transmitted to the compression spring 5 is smaller than the pressure borne by the compression spring 5 during installation, the compression spring 5 is not compressed, the impact kinetic energy disappears on the way of drawing the sliding seat 2 to return to the initial position, and the movable door 16 is finally drawn by the towing hook 3 to return to the initial position of the double-buffer limit stopper of the movable door under the action of the tension spring 7;

II, secondly: the impact force is great, the impact force transmitted to the compression spring 5 is greater than the preset pressure when the compression spring 5 is installed, the compression spring 5 generates buffer compression under the action of the impact force, the impact force is great, the generated compression amount is large, namely, the buffer stroke is also great, and otherwise, the impact force is small and the buffer stroke is also small. When the impact force transmitted to the compression spring 5 is smaller than the thrust force of the compression spring 5 pressing against the cylinder body of the damper 4, the damper 4 returns to the static mounting position, the damper 4 finishes the rest buffering work, if the impact force is relatively small and disappears before the traction sliding seat 2 returns to the starting position, and the pulling force of the tension spring 7 drags the movable door 16 to the starting and stopping position;

thirdly, the method comprises the following steps: if the transmitted impact force is very large, the damper 4 and the compression spring 5 on the main buffer mechanism quickly reach the maximum buffer stroke, and the root of the connector 8 fixed at the end part of the damper 4 rigidly transmits impact pressure to the base after returning to the initial position.

Example two: the second embodiment differs from the first embodiment in that the compression spring 5 is replaced with a rubber column.

It is to be understood that the foregoing is only a preferred embodiment of the present invention, and not intended to limit the scope of the invention, which is defined by the following claims and drawings.
