The working principle of the utility model is described below by taking the drawer as an example from opening to closing:
when the drawer is opened, the opening/closing mechanism 1 and the lock release mechanism 2 are separated, the energy of the energy storage spring 41 is released, the positioning rod 44 is abutted against the self-suction groove 54 of the cam 53 through the free end of the first positioning rod 44a, and the components in the opening/closing mechanism 1 are in a static state against the pulling force of the self-suction spring 62. When the drawer is gradually closed, the adjustment slide 23 of the latch release mechanism 2 is gradually engaged with the rocker 51, as shown in fig. 3.
As the drawer is further closed, the adjusting slide 23 continues to push the swing rod 51 and the cam 53 to rotate clockwise, the swing rod 51 slides into the swing hook 24 of the latch release mechanism 2, the self-sucking slot 54 of the cam 53 pushes the free end of the first positioning rod 44a to move the third positioning rod 44c and the first positioning pin 44d along the positioning guide slot 44f, meanwhile, the positioning rod 44 drives the sliding sleeve 43 to compress the energy storage spring 41, and the other side wall of the virtual slot 55 of the cam 53 is close to the push rod 52, as shown in fig. 4.
As the drawer is further closed, the free end of the first positioning rod 44a gradually separates from the self-suction groove 54 of the cam 53, is pushed up by the cam 53 to be tilted, slides into the positioning buckle 45 and abuts against the positioning buckle, and the energy storage spring 41 completes energy storage; the self-priming lever 61 slides gradually into the self-priming slot 54, triggering the drawer self-priming to close under the action of the self-priming spring 62, the cam 53 automatically drives the push rod 52 to compress the buffer 7, and at this time, the drawer is completely closed, as shown in fig. 5.
When the drawer is closed, and the user adopts the automatic drawer opening function, the user only needs to press the drawer, and at this time, the push rod 52 drives the sliding sleeve 43 to retreat the free end of the first positioning rod 44a, and the free end of the first positioning rod 44a swings downwards under the action of the positioning spring 44g to separate from the positioning buckle 45. After the user releases his hand, the buffer 7 and the energy-storing spring 41 release energy, and the push rod 52 is pushed to drive the swing rod 51 and the cam 53 to rotate counterclockwise synchronously, so as to overcome the acting force of the self-priming spring 62, so that the self-priming groove 54 is separated from the self-priming lever 61 until the free end of the first positioning rod 44a slides into and pushes against the self-priming groove 54, and the swing rod 51 and the swing hook 24 tend to separate and return to the state shown in fig. 3.
When the drawer is closed, when a user directly pulls out the drawer manually, the free end of the first positioning rod 44a is kept to abut against the positioning buckle 45, the energy storage spring 41 keeps in an energy storage state, the buffer 7 releases energy, the swing rod 51, the push rod 52 and the cam 53 rotate anticlockwise, the acting force of the self-suction spring 62 is overcome, the self-suction groove 54 is separated from the self-suction lever 61, and the drawer is opened until the swing rod 51 and the swing hook 24 tend to be separated.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, various modifications and substitutions can be made without departing from the technical principle of the present invention, and these modifications and substitutions should also be regarded as the protection scope of the present invention.
