The description such as upper and lower, left and right used in utility model is only the phase with respect to each ingredient of this utility model in accompanying drawing
Mutually for position relationship.
Additionally, unless otherwise defined, the technology of all of technology used herein and scientific terminology and the art
The implication that personnel are generally understood that is identical.Term used in the description is intended merely to describe specific embodiment herein, and not
It is to limit the present invention.Term as used herein " and/or " include the arbitrary of one or more related Listed Items
Combination.
With reference to Fig. 1, show the schematic perspective view of one embodiment of this utility model, it includes base 100, cover plate 200
With elastic component (not shown).
Cover plate 200 is connected on base 100 and can rotate to realize the action opening and closing, specifically by respect thereto 100
, the top of base 100 is extended with two parallel engaging lugs 110, is provided with the pin 120 of level, cover plate between engaging lug 110
To being provided with pin hole (not shown) by pin on 200, pin 120 is located in pin in the hole to realize turning of cover plate 200
Dynamic, certainly, cover plate 200 can also be realized rotating by other conventional structures.
Cover plate 200 mainly includes a covering part 210 realizing shielding function, and covering part 210 is preferably a slab construction,
The head end of covering part 210 is provided with a vertical shifting block 220, and the front side wall of this shifting block 220 is provided with groove 221, is easy to user and applies
To open cover plate 200, covering part 210 is provided with a boss 230 in the other end (i.e. tail end) with respect to shifting block 220 to power.
With reference to Fig. 2 and Fig. 3, show that this utility model cover plate is in the side view closed with opening, by figure
Understand, projection 230 includes rear wall 231, diapire 232 and the arc surface between rear wall 231 and diapire 232 233, its
Middle rear wall 231 and arc surface 233 form support division, and support division and covering part 210 are located at cover plate 200 center of rotation (i.e. respectively
Pin 120) both sides to form a lever construction.
Base 100 is provided with a body structure 130 in the lower section of engaging lug 110, and the inside of this body structure is provided with one and houses
Cavity, what elastic component 300 was vertical is placed in this containing cavity body, and bottom is supported with the diapire of cavity, and top can be in support division
Effect is lower to there is compression motion.
Preferably, for the ease of the more preferable compression elastic piece of support division, this utility model also includes slide block 400, slide block
400 tops being socketed in elastic component 300, that is, support division is by this slide block 400 indirectly compression elastic piece 300.It is of course also possible to
Directly substitute slide block 400 with being fixedly arranged at pressure block on the top of elastic component or bearing plate.
Because support division and covering part form leverage, thus covering part 210 during upwardly opening support division then to
Lower rotation, and the movement locus of support division are circle, therefore will there is a minimum point in support division in motor process, and this is
Low spot is critical point, and in cover plate is from the starting stage opened to the rotation process of critical point, arc surface 233 progressively compresses bullet
Property part 300, elastic component 300 then gives cover plate 200 1 and stops the opposition that it opens, and gets over the closer to critical point active force
Greatly, the unexpected unlatching of cover plate 200 can therefore be prevented；There is resilience in cover plate 200 elastic component 300 after crossing critical point, force cunning
Block 400 is supported with the rear wall 231 of projection, thus give the active force that cover plate 200 is maintained at opening, i.e. cover plate 200
Open and close are required for certain active force and just enable, and so, can avoid unexpected opening when cover plate 200 is closed
Open the safety it is ensured that switching；It is in and will not voluntarily close during opening again, it is to avoid the operation to switch causes to hinder.
Preferably, the diapire 232 of projection 230 is an inclined-plane, and the lowermost end on this inclined-plane connects circular arc wall 233, and it can be kept away
Exempt from projection 230 to rub and slide block 400 between in rotation process.
Additionally, the elastic component 300 in this utility model includes spring or shell fragment, in the present embodiment, adopt spring.
With reference to Fig. 4, the invention also discloses a kind of equipment, as illustrated, it includes places the recessed of switch 500
Groove, above-mentioned switch protection covers at the notch of groove.
It is more than that preferable enforcement of the present utility model is illustrated, but the invention is not limited to described reality
Apply example, those of ordinary skill in the art also can make a variety of equivalent variations without prejudice on the premise of this utility model spirit
Or replace, these equivalent deformation or replacement are all contained in the application claim limited range.
