The utility model aims at providing an easy operation opens convenient and fast to the part that opens and shuts and all can be spacing automatically after opening and closing, the extensive device that opens and shuts in applicable field.
In order to achieve the above purpose, the utility model adopts the technical scheme that: the utility model provides a device opens and shuts, includes button, slider, connecting rod, the portion that opens and shuts, pivot, the front portion of button is equipped with an inclined plane one, but the slider back-and-forth movement, the rear portion of slider is equipped with an inclined plane two, the inclined plane one of slider with the laminating of inclined plane two of button, the slider left and right sides respectively is equipped with one and keeps off the position contact, the connecting rod is equipped with the shaft hole, the connecting rod passes through the shaft hole cover is established can rotate in the pivot, the one end of connecting rod with the portion fixed connection that opens and shuts, the other one end of connecting rod is provided with an inclined plane contact, the inclined plane contact with on the slider keep off the position contact laminating, the cover.
Preferably, the top of the key is a pressing area.
Preferably, a return spring is provided at a front portion of the slider.
Preferably, the bottom of the key is connected with a spring.
Preferably, one end of the torsion spring is fixedly connected with the rotating shaft, and the other end of the torsion spring is fixedly connected with the transmission connecting rod.
The utility model provides a working principle of device opens and shuts: when the opening and closing part needs to be opened, the key is pressed downwards, the key moves downwards, and the inclined surface on the key moves downwards together. The spring under the key is compressed. When the inclined surface of the key moves downwards, the inclined surface of the sliding block can be pushed to move forwards due to the unique angle design, and the longitudinal displacement is converted into the transverse displacement in the process. The inclined plane of slider can drive whole slider and move forward when removing, and the spring of slider front end is compressed, keeps off a position contact on the slider and also moves forward simultaneously. When the gear contact on the sliding block moves forwards and is separated from the inclined contact on the connecting rod, the accumulated force of the torsion spring on the rotating shaft can be released, so that the opening and closing part and the connecting rod rotate anticlockwise by taking the rotating shaft as an axis, and the opening working effect is generated. When the key is released, the spring at the bottom of the key can be bounced, the key is reset, the spring at the front end of the sliding block can be extended, the sliding block is reset, and the opening of the opening and closing part is completed.
When the opening and closing part needs to be closed, the opening and closing part is pressed, and the wings and the connecting rods rotate by taking the rotating shaft as the axis under the stress as the connecting rods on the opening and closing part are sleeved on the rotating shaft. During the rotation of the opening and closing part and the connecting rod, the inclined contact on the connecting rod pushes the gear contact on the sliding block forwards, and meanwhile, the sliding block moves forwards together. When the sliding block and the gear contacts on the two sides of the sliding block are pushed to the farthest end by the inclined contact on the connecting rod and separated, the compression spring in front of the sliding block releases elastic force to enable the sliding block to rebound and reset, and the gear contacts on the two sides of the sliding block can block the inclined contact on the connecting rod again to enable the connecting rod and the opening and closing part to be positioned immovably, so that the opening and closing part is closed.
Compared with the prior art, the utility model has the advantages that the slide block is matched with the slide block through the inclined plane, the slide block is matched with the inclined plane contact of the connecting rod through the inclined plane contact of the button, so that the opening and closing part can be opened only by pressing one operation of the button, the opening and closing part can be positioned at the opening position after being opened, the closing of the opening and closing part can be completed only by pressing the opening and closing part, and the opening and closing part can be positioned at the closing position. Compared with the prior art, the switch has the advantages of ingenious design, convenient and fast switching and suitability for different occasions.

Detailed Description
Make the purpose, technical scheme and advantage of the embodiment of the utility model more clear, will combine below in the embodiment of the utility model the drawing, it is right to technical scheme in the embodiment of the utility model carries out clear, completely the description.
Referring to fig. 1 to 3, in the embodiment of the present invention, the opening and closing device includes a button 1, a slider 2, a connecting rod 3, an opening and closing portion 4, and a rotating shaft 5, the top of the button 1 is a pressing area, the front portion of the button 1 is provided with a first inclined surface 6, the bottom of the button 1 is connected to a spring, the slider 2 can move back and forth, the front portion of the slider 2 is provided with a return spring, the rear portion of the slider 2 is provided with a second inclined surface 7, the second inclined surface 7 of the slider 2 is attached to the first inclined surface 6 of the button 1, the left and right sides of the slider 2 are respectively provided with a gear contact 8, when the slider 2 is displaced, the gear contact 8 moves along with the slider 2, the connecting rod 3 is provided with a shaft hole, the connecting rod 3 is sleeved on the rotating shaft 5 and can rotate, one end of the connecting rod 3 is fixedly connected to the opening and closing portion 4, the rotating shaft 5 is sleeved with a torsion spring 10, one end of the torsion spring 10 is fixedly connected with the rotating shaft 5, and the other end of the torsion spring 10 is fixedly connected with the connecting rod 3.
When the opening and closing part 4 needs to be opened, the key 1 is pressed downwards, the key 1 moves downwards, and the inclined surface 6 on the key 1 moves downwards together. The spring under the key 1 is compressed. When the inclined surface 6 of the key 1 is displaced downwards, the inclined surface 7 of the sliding block 2 is pushed to move forwards due to the unique angle design, and the longitudinal displacement is converted into the transverse displacement in the process. The inclined surface 7 II of the sliding block 2 can drive the whole sliding block 2 to move forwards while moving, a spring at the front end of the sliding block 2 is compressed, and meanwhile, a gear contact 8 on the sliding block 2 also moves forwards. When the gear contact 8 on the sliding block 2 moves forward and is separated from the inclined contact 9 on the connecting rod 3, the accumulated force of the torsion spring 10 on the rotating shaft 5 is released, so that the opening and closing part 4 and the connecting rod 3 rotate anticlockwise by taking the rotating shaft 5 as an axis, and the opening working effect is generated. When the key 1 is loosened, the spring at the bottom of the key 1 can be bounced, the key 1 is reset, the spring at the front end of the sliding block 2 can be extended, the sliding block 2 is reset, and the opening and closing part 4 is opened.
