The containing bin 11 is vertically provided with a guide hole 12, the trigger rod 3 is telescopically installed in the guide hole 12, the trigger rod 3 is provided with a driving spring 13, and the driving spring 13 always pushes the trigger rod 3 outwards.

The trigger bar 3 is provided with a linkage seat 31, and one end of a driving arm 64 is hinged on the linkage seat.

The trigger rod is connected with an adjusting rod 32 in a threaded mode, and the adjusting rod 32 is sleeved at the lower end of the trigger rod 3 and extends out of the accommodating bin 11.

The linkage rod 6 is fixedly provided with a driving rod 62, the driving rod 62 is provided with a driving groove 63, and the driving pin penetrates through a driving arm 64 and then is placed in the driving groove 63 and is connected with the driving rod 62.

And a locking guide groove 73 is transversely arranged on the locking plate 7, and the positioning pin penetrates through the linkage rod 6 and is placed in the locking guide groove 73 to limit the displacement stroke of the locking plate 7.

The positioning block 72 protrudes from the outer contour of the locking plate 7 and extends into the displacement stroke of the locking plate 7.

A push spring 82 is arranged between the locking groove 8 and the locking block 81, and the push spring 82 pushes the locking block 81 to be always ejected outwards.

The lower end face of the locking block 81 is provided with a guide slant 83, and the guide slant 83 is arranged in a direction deviating from the positioning block 72.

The hanging needle groove 92 is an inner groove formed in the wall of the accommodating bin 11, the trigger rod 3 is arranged in an arc shape as an oscillating center, the locking groove 93 is arranged at the bottom of the hanging needle groove 92, a reset blocking surface 94 is further arranged at the position corresponding to the hanging needle groove 92, and the hanging needle groove 92 and the locking groove 93 are communicated.

The working principle is as follows: when the opening device is used, the main body of the opening device is arranged in the cabinet body, so that the trigger rod and the reverse rod enter the movable range of the cabinet door. As shown in fig. 4, when the cabinet door is closed, the rebounding rod retracts into the main body, the hanging needle 91 is locked in the locking groove 93, the position of the trigger rod is locked, the positions of the driving arm 64 and the linkage rod are locked, and in this state, the locking plate 7 presses against the locking rod 42 on the swinging seat 41 to lock the position of the rebounding rod and prevent the rebounding rod from opening outwards.

As shown in fig. 5, when a user needs to open the cabinet door, the cabinet door is pressed inward, the push door pushes the trigger rod to slide inward, the trigger rod pushes the driving arm 64 to swing through the lever principle, so that the hanging needle 91 on the driving arm moves downward to force the hanging needle 91 to disengage from the hanging needle groove 92, and in the disengaging process, the hanging needle 91 impacts the reset stop surface 94 at the bottom of the hanging needle groove 92 to deflect. When a user presses the cabinet door and releases the pressure on the cabinet door, the counter-acting force of the locking rod 42, which acts on the locking plate 7 in the opposite direction, pushes the linkage rod 6 to swing in the opposite direction, and the driving spring 13 sleeved on the triggering rod pushes the triggering rod 3 outwards. The linkage rod 6 drives the driving arm 64 to move reversely through the driving rod 62, and drives the hanging needle 91 to swing upwards. When the linkage rod 6, the driving rod and the trigger rod are pulled, the linkage rod 6 drives the locking plate 7 to deflect, and the positioning block 72 on the locking plate 7 is forced to be separated from the locking block 81. After the locking plate 7 loses the supporting force, the limit of the locking rod 42 on the swinging seat 41 is released, and the swinging seat 41 always rotates towards the door opening direction under the action of the tension spring 5, so that the door is pushed to the open state by the rebound rod on the swinging seat 41, and finally the door opening state shown in fig. 7 is achieved.

As shown in fig. 8, when a user needs to close the cabinet door, the rebounding rod is pushed to close inwards when the cabinet door is closed, when the rebounding rod is closed, the locking rod 42 on the swing seat 41 is used to push the locking plate 7 to move in the reverse direction, after the locking plate 7 is stressed, the locking plate acts on the linkage rod and the driving arm in the reverse direction, so that after the driving arm 64 is forced to swing, the hanging plate 9 and the hanging needle 91 on the driving arm are driven to move downwards, and after the hanging needle 91 is forced to be hooked with the hanging needle groove 92 again, the positions of the driving arm and the linkage rod are locked. As the door closing angle gradually decreases, the cabinet door continues to push the rebounding rod to a completely closed state, when the cabinet door reaches the closed state, the locking plate 7 rebounds and resets to be pressed against the locking rod 42 again, and meanwhile, the locking block 81 resets to be pressed against the positioning block 72 arranged on the locking plate 7 to lock the relative position between the locking plate 7 and the swing seat 41; thereby indirectly playing the effect of relocking the lock plate, avoiding the bounce-back pole outwards flicking and opening the cabinet door under the non-operation condition. Consequently, the cabinet door of having installed this opening device need not at cabinet door surface mounting handle, has kept the clean and tidy fashion of cabinet door, and simultaneously, the cabinet door can adopt to press the rebound formula to open, and convenient operation is swift, is rich in science and technology and feels, so can extensively use widely.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications are within the scope of the invention as claimed.
