The side wall of the main arm body 6 is provided with a buffer rack 58 which is meshed with a buffer gear 59 arranged in the accommodating cavity 5.
Working principle: as shown in fig. 1 and 2, the rebound device comprises a main body arranged in a cabinet body 1 and a lock catch 3 arranged on a cabinet door 2; the cabinet doors are connected through hinges with self-resetting function.
As shown in fig. 8, the cabinet door in a normal state is closed under the action of the self-resetting hinge 11, and the tightness of the cabinet door is maintained, and in this state, the lock column part of the lock catch is propped against the holding forceps on the end face of the main arm body.
As shown in fig. 9, when the user presses the cabinet door, the main arm body is pushed to retract inwards by the lock catch, the tail of the main arm body is propped against the push block 86 of the trigger rack, the trigger rack 81 is pushed by the push block 86, when the trigger rack 81 moves inwards, the rebound rack is pushed outwards by the synchronous gear 8, so that the locking hook 83 is pushed to move outwards, and the locking hook drives the hanging needle to be separated from the locking sliding groove 51 and enter the reset sliding groove 52. When the hanging needle enters the reset chute 52, the hanging needle loses the locking of the locking hook 83 and the rebound rack 82, and the locking hook 83 and the rebound rack 82 move inwards under the action of the first tension spring 53. When the rebound rack 82 moves inwards, the synchronous driving synchronous gear 8 rotates, and when the synchronous gear 8 rotates, the trigger rack 81 meshed with the synchronous gear is driven to slide outwards, and the trigger rack pushes the main arm body 6 to pop outwards by using the driving block 61 at the tail part of the trigger rack, so that the effect of pushing the cabinet door to open outwards is realized.
As shown in fig. 10 and 11, after the main arm body is pushed outwards for a certain stroke, the locking hook 83 is hung and buckled with the pressing block 62, and the hanging and buckling pushes the driving block 61 to do telescopic motion; the inner end of the driving block 61 is connected with the holding clamp 7 through a connecting rod 63, and when the driving block 61 moves inwards, the holding clamp 7 is pushed to be closed, so that the holding clamp is clamped and fixed on the lock column 32 of the lock catch 3.
As shown in fig. 12, when the user opens the cabinet door, the holding forceps 7 is closed and clamped with the lock posts 32, so that the door opening force can continuously pull the main arm body 6 outwards when the user opens the door. When the door is opened to a certain angle, the main arm body 6 moves outwards to the maximum stroke, the main arm body pulls the locking hook to move outwards by using the pressing block 62 at the tail part of the main arm body, the locking hook is forced to swing sideways and separate from the pressing block 62 under the action of side thrust, the hanging needle on the locking hook reenters the locking chute from the reset chute 52, and when the locking hook is reset, the first tension spring 53 is pulled to stretch so as to prepare for the next rebound.
The following are to be described: after the locking hook swings sideways and is separated from the pressing block 62, the pressing block 62 loses tension, so that under the action of door opening tension, the holding clamp is opened, the holding clamp is separated from the lock column 32, and the cabinet door can be opened continuously. And the main arm body 6 is retracted inwards to reset under the action of the second tension spring 54.
As shown in fig. 13, when the cabinet door is completely opened, the main arm 6 is retracted inwards to be reset under the action of the second tension spring 54. Therefore, compared with the prior art, the rebound device in the scheme has the advantages that the main arm body is retracted into the cabinet body in the state that the cabinet door is opened, so that the cabinet door can be kept clean after being opened. Therefore, the problem that a user easily collides with the door opener when the traditional door opener is used is avoided. The use requirement is met, and meanwhile, the aesthetic property of the lamp is maintained during use.
As shown in fig. 8, when the cabinet door in the present case needs to be closed, the user only needs to manually close the cabinet door to a certain angle, and the cabinet door automatically pushes the cabinet door to be closed under the action of the self-resetting hinge 11. The tightness of the cabinet door is maintained. When the cabinet door is closed, the cabinet door drives the lock catch on the cabinet door to contact with the main body by utilizing the lock column of the cabinet door, so that preparation is made for the next pressing and opening.
The foregoing has shown and described the basic principles and main features of the present invention and the advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present invention, and various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined in the appended claims.
