Description

A kind of switching mechanism of storage card lid

Technical field

The utility model is the switching mechanism about a kind of storage card lid, particularly the switching mechanism that covers about the small and exquisite storage card of a kind of space structure.

Background technology

Storage card (SD card) on digital storage products, use very extensively, storage card is built the effect of protection storage card.Digital storage products outward appearance small and exquisite need the bulk of the switching mechanism of storage card lid do try one's best little.For example, mobile phone enters each family just at leisure as a kind of media of communication of modern people.The user is more and more higher to the performance requirement of mobile phone now, and profile is more and more exquisiter small and exquisite.Along with 3G mobile begins to use, because the finite capacity of the storage of itself needs to store data with storage card (SD card).The switching mechanism of storage card lid commonly used at present comprises flip piece and Ka Gai, flip piece is made by rubber, the inboard and the SD clamping that are located at the storage card lid are touched, can well protect the SD card, Ka Gai sticks on the lateral surface of flip piece, and flip piece is provided with two flip-arms, offers hole clipping on the free end of this flip-arm, convex with fixture block on the position corresponding with this flip-arm of the SD card insert opening on the mobile phone bottom, the hole clipping of flip-arm snaps in this fixture block and can rotate around this fixture block; Upside and lower side at Ka Gai convex with locating convex block respectively, offer the draw-in groove corresponding with this locating convex block on the SD of phone cover card insert opening mouth wall, and when storage card lid fastening state, this locating convex block tightly snaps in this draw-in groove.The switching mechanism of said memory card lid is because the hole clipping on the flip-arm should snap on the fixture block, guarantee to bear certain pulling capacity (1.5 kgf) again, therefore the size of flip-arm can not be done too for a short time, the size of Ka Gai is just bigger, and the small and exquisite property that this and cell phone appearance require has produced contradiction, because, the hole clipping of flip-arm snaps in this fixture block should realize location to flip body, make it rotate the structural relation complexity of hole clipping and fixture block, requirement on machining accuracy height around this fixture block again.

The utility model content

The utility model purpose is to provide the switching mechanism of the small and exquisite storage card lid of a kind of space structure.

The purpose of this utility model is achieved through the following technical solutions:

The switching mechanism of a kind of storage card lid of the utility model comprises the cover, flip piece and the Ka Gai that are provided with the storage card insert opening; This Ka Gai sticks on the lateral surface of this flip piece, and its upper and lower side convexes with locating convex block respectively, offers the corresponding draw-in groove of locating convex block that covers with this card respectively on the upper and lower wall of the insertion mouth of this cover; This flip piece is provided with two flip-arms, and the free end of these two flip-arms extends to form the elasticity fixture block to the side respectively; The inboard that is positioned at this insertion mouthful on this cover is formed with two hole clippings corresponding with this flip-arm, and these two hole clippings are formed with two expanded bore respectively on closing on outside the end of this cover roof or diapire; This elasticity fixture block passes this hole clipping and can move in this expanded bore, and can block only on this hole clipping wall.After adopting this structure, make the structure of the switching mechanism of storage card lid become simple, simultaneously, can do the size along flip piece length and Width of flip-arm to such an extent that lessly just can bear certain pulling capacity (1.5 kgf), thereby make the space structure of switching mechanism of this storage card lid small and exquisite.

The utility model is in above-mentioned basis, wherein:

Described elasticity fixture block is wedge shape, and being convenient to this elasticity fixture block can enter expanded bore by hole clipping more easily.

The free end of described two flip-arms length direction of described this flip piece respectively extends to form the elasticity fixture block to two sides, makes the size along the flip piece Width of flip-arm do forr a short time.

Between these two hole clippings, convexing with two limited blocks that can replace described flip piece madial wall on the insertion mouth wall of described cover, this flip piece is positioned in position, protection stores card better.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Fig. 1 is the solid assembling partial schematic diagram of the switching mechanism of a kind of storage card lid of the utility model.

Fig. 2 is that schematic perspective view is looked up in the part of top cover of the switching mechanism of a kind of storage card of the utility model lid.

Fig. 3 is the state that the opens partial schematic diagram of the switching mechanism of a kind of storage card lid of the utility model.
