The embodiment of the utility model provides a drawer damping device, including buffer 1, extension spring 2, movable block 3, swing piece 4 and damping frame 5, wherein:
one end of the damping frame 5 is provided with a buffer mounting position 51 and a tension spring mounting position 52, the other end of the damping frame 5 is provided with a slide rail 53, one side of the slide rail 53 is provided with an avoiding notch 54, and the other side of the slide rail 53 is provided with a braking groove 55; the swinging block 4 and the moving block 3 are respectively provided with a sliding chute 45 and a sliding chute 35, the swinging block 4 and the moving block 3 are arranged on a sliding rail 53 of the damping frame in tandem through the sliding chute 45 and the sliding chute 35, the swinging block 4 is provided with a shaft hole 41, the moving block 3 is provided with a shaft post 31, and the moving block 3 is sleeved in the shaft hole 41 of the swinging block 4 through the shaft post 31; the buffer 1 is installed and limited on the buffer installation position 51, and the buffer needle head of the buffer 1 is clamped on the clamping groove 33 of the moving block 3; the extension spring 2 is installed on extension spring installation position 52, and extension spring 2 one end joint is on damping frame 5, and the other end joint is on the joint groove 34 of movable block 3.
the shaft 31 of the moving block 3 faces downward, and the moving block 3 presses the swinging block 4 downward through the shaft 31 and the shaft hole 41, thereby preventing the swinging block 4 from falling off. The moving block 3 is provided with a clamping groove 32, the damping frame 5 is provided with a clamping bulge 56 at the initial position of the slide rail 53, the clamping bulge 56 and the clamping groove 32 limit the moving block 3 in the vertical direction, and the moving block 3 cannot fall off.
the back surface of the swing block 4 is provided with a stopper projection 44, and when the swing block 4 moves to the position of the stopper groove 55 of the slide rail 53, the stopper projection 44 is caught in the stopper groove 55. The front surface of the swinging block 4 is provided with a reset slope 42 and a drawer movable rail clamping groove 43, and the reset slope 42 is connected with the drawer movable rail clamping groove 43. When the card of the drawer movable rail is not clamped on the drawer movable rail clamping groove 43 and is in an abnormal state (namely the drawer is pulled open, and the damper is in a closed state), the drawer movable rail can be forcibly reset through the reset slope 42, and the card of the drawer movable rail is clamped on the drawer movable rail clamping groove 43 again.
The utility model provides a drawer damping device's theory of operation as follows:
when the drawer is opened, the clamping piece of the movable rail of the drawer is clamped in the clamping groove of the movable rail of the drawer of the swinging block, the swinging block is driven by external force to slide forwards along the sliding rail by overcoming the elasticity of the tension spring and the resistance of the damper, and the swinging block further drives the moving block to move forwards along the sliding rail and simultaneously drives the buffer needle head and the tension spring of the damper to move as the swinging block is connected with the moving block; because the swing block and the moving block are connected in a rotating mode, when the swing block moves to the position of the avoidance notch and the braking groove, the swing block can deflect, the braking protrusion of the swing block can be clamped in the braking groove of the damping frame, the swing block stops being limited and stops moving at the moment, the clamping piece of the drawer movable rail leaves the drawer movable rail clamping groove of the swing block, and the drawer movable rail continues to move to open the drawer.
When the drawer is closed, when the movable rail of the drawer moves backwards to the position of the drawer damping device, the clamping piece of the movable rail of the drawer is clamped in the clamping groove of the movable rail of the drawer of the swinging block, the swinging block is driven by external force to deflect to the normal position, the restoring force of the tension spring overcomes the resistance of the damper, the movable block and the swinging block are driven to move backwards, and the drawer is slowly recovered and closed.
The utility model provides a drawer damping device's equipment process as follows:
The damping device comprises a damping frame, a movable block, a swinging block, a tension spring, a damper and a buffer needle head, wherein the movable block and the swinging block are assembled together firstly, one end of the tension spring is fastened in the movable block, the movable block and the swinging block are placed on a slide rail of the damping frame, the tension spring is placed on a tension spring mounting position at the moment, the other end of the tension spring is clamped on the damping frame, the damper is mounted and limited on a buffer mounting position, and the buffer needle head of the buffer is clamped on the movable block.
Compared with the prior art, the utility model provides a drawer damping device, simple structure, the equipment is convenient, and the reliability is high.
the previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
