The utility model is described in detail below with reference to the attached drawings and alternative embodiments.
As shown in fig. 1 to 5, as an embodiment of the present utility model, a buffer closing mechanism is disclosed, which includes a track 1, a buffer driving assembly 2, a first clamping slider 3, and a second clamping slider 4; the buffer driving assembly 2 is arranged in the track 1, the first clamping slider 3 is slidably arranged at one end of the track 1, and the second clamping slider 4 is slidably arranged at the other end of the track 1; the first clamping slide block 3, the second clamping slide block 4 are linked with the buffer end of the buffer driving assembly 2.

Specifically, the buffer closing mechanism of the utility model can be applied to the door and window 6 with heavy weight, reduces the speed of closing the door and window 6, and avoids hand injury caused by large weight and large inertia when closing the door and window 6, and when opening the door and window 6, the first clamping slide block 3 is driven to move and reset by the self inertia force when the door and window 6 moves. At this time, the moving object is the moving object. Specifically, when the door and window 6 is closed, the buffer driving component 2 provides buffer moving force for the first clamping slider 3 when the door and window is closed, so that the door and window 6 can be slowly closed.
Alternatively, as shown in fig. 5, the buffer drive assembly 2 includes a cylinder 21, a first elastic member 22, and a connection block 23; one end of the first elastic piece 22 is fixed on the track 1, the other end is fixed on the connecting block 23, and a piston rod 211 of the air cylinder 21 is fixed on the connecting block 23; the connection block 23 is linked with the first detent slider 3. When the first positioning slider 3 is in the initial position, the first elastic member 22 is stretched or compressed to store the force, and the piston rod 211 of the cylinder 21 is stretched. In this scheme, the buffer closing of the buffer driving assembly 2 to the moving object is realized through the cooperation of the cylinder 21 and the first elastic member 22. When the moving object is not closed yet, the first clamping slider 3 is positioned at the initial position, the first elastic piece 22 is stretched or compressed to store force, and the piston rod 211 of the air cylinder 21 is stretched; when the moving object is closed, the moving object pushes the first clamping slider 3 to move, the first elastic member 22 contracts to drive the first clamping slider 3 to move to close the moving object, and meanwhile, the piston rod 211 of the air cylinder 21 also contracts, that is, the first elastic member 22 contracts or stretches, and meanwhile, the contraction resistance of the air cylinder 21 needs to be overcome, so that the moving object is slowly closed. The interaction of the first elastic member 22 and the air cylinder 21 provides a buffer moving force to the moving object so that it is slowly closed.
Specifically, as shown in fig. 5, the first elastic member 22 may be a spring, and the spring is sleeved on the piston rod 211. One end of the spring can be clamped on the connecting block 23, and the other end can be clamped on the track 1. One end of the piston rod 211 may be inserted in the connection block 23.

In this embodiment, since the contraction portion 32 is stressed and can contract, the contraction portion 32 can make the moving object not easily rebound due to inertia impact on the first clamping portion 31 after being clamped in the clamping space 33, so as to ensure that the moving object is clamped in the clamping space 33. When the moving object is reversely pulled to be opened, the contraction part 32 is stressed to contract again, the moving object is separated from the clamping space 33, and is clamped with the second clamping slide block 4 after moving for a certain distance, the second clamping slide block 4 moves, and the first clamping slide block 3 is driven to reset through the connecting frame 5.

Specifically, the jacking structure is a second elastic member (not shown), the second elastic member is installed in the installation cavity 34, the shrinkage portion 32 is pressed against the second elastic member, and the second elastic member jacks up and extends the shrinkage portion 32 from the installation cavity 34. When the constriction 32 is stressed, the spring is compressed and the constriction 32 constricts. However, the force of the contraction portion 32 needs to overcome the elastic force of the spring to contract, and therefore, the rebound when the moving object is closed can be limited. The second elastic member may be a spring. In another embodiment, the jacking structure is a first magnet (not shown), and the first magnet is mounted on the bottom surface of the mounting cavity 34; the constriction 32 is provided with a second magnet (not shown) opposite to the first magnet, the first magnet and the second magnet being repelled. In this embodiment, the retraction portion 32 is lifted up and extended by the principle of magnetic pole repulsion. When the constriction 32 is forced, the constriction 32 is retracted into the mounting cavity 34 against the repulsive force.

In this embodiment, the height of the third clamping portion 42 is smaller than the height of the second clamping portion 41, so that the moving object can be conveniently clamped between the second clamping portion 41 and the third clamping portion 42. The third clamping portion 42 not only ensures that the moving object can be clamped between the second clamping portion 41 and the third clamping portion 42 when the moving object is opened, and is not easy to rebound due to collision with the second clamping portion 41, but also can be separated from the second clamping portion 41 and the third clamping portion 42 when the moving object is closed by a certain force.
Alternatively, as shown in fig. 9, the top surface of the third detent portion 42 is an arc surface, and the height of the side away from the second detent portion 41 is lower than the height of the side close to the second detent portion 41.

And the height of the side far from the second clamping part 41 is lower than the height of the side close to the second clamping part 41, so that a moving object can be clamped between the second clamping part 41 and the third clamping part 42 more easily.
Optionally, as shown in fig. 3, a first slideway 11 is provided at one end of the track 1 far away from the first clamping slider 3, and the second clamping slider 4 is slidably installed in the first slideway 11 and is rotationally connected with the connecting frame 5; the two sides of the first slideway 11 are extended and provided with sliding rails 111, one end of the sliding rail 111 away from the first clamping slide block 3 sinks to form a clamping cavity 112, and when the second clamping slide block 4 moves to the clamping cavity 112, the second clamping slide block 4 is clamped into the clamping cavity 112 to limit. In this solution, the second clamping slider 4 is positioned by providing a clamping cavity 112 at one end of the sliding rail 111 to form a clamping position for the second clamping slider 4. When the second clamping slider 4 is clamped into the clamping cavity 112 to limit, the first clamping slider 3 is at the initial position, the first elastic piece 22 is stretched and accumulated, and the piston rod 211 of the air cylinder 21 is stretched.
Alternatively, as shown in fig. 6 and 9, first protrusions 43 are disposed on two sides of the second clamping slider 4, and the first protrusions 43 are abutted against the sliding rail 111; when the second clamping slider 4 moves to the clamping cavity 112, the first protrusion 43 is clamped into the clamping cavity 112 to limit. In this scheme, first protruding 43 cooperates with slide rail 111, screens chamber 112, and it is stable to remove, and the screens is effectual.
Optionally, as shown in fig. 3, a second slideway 12 is provided at one end of the track 1 far away from the second clamping slider 4, the first clamping slider 3 is slidably mounted in the second slideway 12, and the first clamping slider 3 is stably mounted and stably slides.
The working principle of the buffer closing mechanism of the utility model is as follows: before the moving object is closed, the second clamping slider 4 is clamped in the clamping cavity 112 through the first bulge 43, and the first clamping slider 3 is in the initial position. When the moving object is closed, the operator pushes the moving object to move towards the direction of the first clamping slide block 3, when the moving object moves to the initial position of the first clamping slide block 3, the moving object is clamped into the clamping space 33, meanwhile, the first bulge 43 is separated from the clamping cavity 112, the first clamping slide block 3 is driven to move continuously, and the second clamping slide block 4 moves synchronously. Due to the interaction of the first elastic member 22 and the cylinder 21, the moving object is slowly closed. When it is desired to open the moving object, the operator pushes the moving object in the reverse direction, and the moving object passes over the constriction 32 and continues to move in the reverse direction. After moving reversely a certain distance, the other end of the moving object gets over the third locking portion 42 and is locked between the third locking portion 42 and the second locking portion 41. Since the moving object is already in a moving state and has a certain inertia force, the second clamping slider 4 can be easily driven to move towards the clamping cavity 112, and at the same time, the connecting frame 5 and the connecting block 23 drive the first elastic member 22 to re-stretch the storage force and the piston rod 211 of the air cylinder 21 to re-extend. When the first protrusion 43 is snapped into the detent cavity 112, the first detent slider 3 is also reset to the initial position.
