Detailed Description

As shown in fig. 1 to 5, in this embodiment, the present invention includes a housing 1 and a flip cover 2 hinged on an upper portion of the housing 1, a rotating shaft 3 and a cover opening spring 4 are disposed in the flip cover 2, a hook 5 and a torsion spring assembly 6 are sleeved on the rotating shaft 3, a hook limiting hole 7 is disposed on an upper end surface of the housing 1, a lower portion of the hook 5 extends from a bottom of the flip cover 2 and is matched with the hook limiting hole 7, a button assembly 8 matched with a lower portion of the hook 5 is disposed on a front end surface of the housing 1, and a lower end of the cover opening spring 4 is matched with the housing 1.

Compared with the defects of the prior art, in the utility model, when the cover is opened, the button assembly 8 is pressed, so that the lower part of the hook 5 is pushed to rotate, at the moment, the hook 5 drives the rotating shaft 3 and the torsion spring assembly 6 to rotate simultaneously, further, the lower part of the hook 5 can be separated from the hook limiting hole 7, and meanwhile, the flip cover 2 can be automatically opened due to the elastic action of the cover opening spring 4; when closing the lid, will flip 2 pushes down for the lower part of couple 5 inserts in the spacing hole of couple 7, make spacing hole of couple 7 can be right again the lower part of couple 5 is spacing, simultaneously the lower extreme compression of spring 4 that uncaps is in on the casing 1, thereby the completion is closed and is covered. Consequently, automatic structure of uncapping pass through couple 5 pivot 3 couple spacing hole 7 reaches uncapping spring 4's setting is in order to realize automatic uncapping, uncapping and press conveniently to reduce cost, automatic bounce after uncapping, just button assembly 8 is located setting up on the preceding terminal surface of casing 1 can easily uncap, can increase the practicality, makes automatic structure of uncapping have easy to use and advantage with low costs.

In this embodiment, couple 5 reaches the quantity of the spacing hole 7 of couple is two, two couple 5 cooperates the setting respectively and is in the both ends of pivot 3, two the spacing hole 7 of couple respectively with two couple 5 cooperatees, torsional spring subassembly 6 is located two between the couple 5. When the button assembly 8 pushes the lower part of one of the hooks 5, the torsion spring assembly 6 and the two hooks 5 can rotate simultaneously due to the arrangement of the rotating shaft 3, so that the two hooks 5 are separated from the two hook limiting holes 7 respectively.

In this embodiment, the torsion spring assembly 6 includes that all cup joint dog 9 and torsion spring 10 on the pivot 3, torsion spring 10 is located dog 9 reaches between the couple 5, a free end of torsion spring 10 is fixed on dog 9, another free end of torsion spring 10 is fixed in flip 2. Due to the arrangement of the torsion spring 10, the rotating shaft 3 can reset after rotating.

In this embodiment, the button assembly 8 includes a button 11, a pushing member 12 and a button return spring 13, the button 11 is embedded in the front end surface of the housing 1, the pushing member 12 and the button return spring 13 are both disposed on the button 11 and both located in the housing 1, and the pushing member 12 is matched with the lower portion of the hook 5. When the button 11 is pressed, the button 11 contacts the lower part of the hook 5 through the push piece 12, and the button return spring 13 is arranged to enable the button 11 to return after being pressed.

In this embodiment, the lower portion of the hook 5 is provided with an inclined portion 15 that is engaged with the hook stopper hole 7. When the cover is closed, the inclined part 15 at the lower part of the hook 5 is contacted with the hook limiting hole 7, so that the hook 5 can overcome the tension of the torsion spring 10 to rotate, and further, the lower part of the hook 5 can be inserted into the hook limiting hole 7 to limit.

In this embodiment, the rotating shaft 3 is a pin.
