Description

Be applied to the miniature lockset of e-machine

Technical field

The utility model particularly is applied in the small-sized lock structure on the electronic equipment about a kind of miniature lockset that is applied to e-machine.

Background technology

Previous computer cabinet door lock normally sees through different structure designs and reaches the expection effect, mainly be to be provided with tongue piece, to be locked on the computer door-plate in the riveting of the rear of door lock, drive tongue piece when rotating synchronously and rotate, the computer door-plate can be opened by the core of turn door lock; Otherwise when desire was closed the computer door-plate, the mat key was fixed with the returning of computer door-plate lid again.

For instance, TaiWan, China patent announcement M338269 number " lock structure improvement ", its characteristics are installed with plural number lock pearl and spring at core and sleeve inner, so when unblanking, need have the specific keys of the decorative pearl on top of an official cap, can carry out unlocking action smoothly, and have preferable anti-theft feature, and can prevent that key from being duplicated by improper.

TaiWan, China patent announcement M242588 number " computer disc driver lock structure " and for example, its characteristics are more organized in this shell block body inboard and are provided with one and plug plate, but this plug plate just the insert group disk that is closed in existing computer disc driver insert in the hole, by this, can reach the purpose of the disk patchhole that blocks disc driver.

By above two cases as can be known, when the fast development of computer peripheral equipment industry, the lock structure design that is applied on the market on the frame is ever-changing, and each family all has unique design, and at every user's demand or the different solution of special-effect proposition.But no matter the lockset of which kind of pattern, because of inside is equipped with lock pearl, spring or other buckle assembly, volume is all very big, complex structure, cost height, and ease of use is not good.

This creator promptly studies according to the lockset of Winchester disk drive frame, and the lasting research of demand that mat solves the market application surface is improved, and finishes development and Design of the present utility model with the design concept of simple scientific principle.

The utility model content

The purpose of this utility model is to propose the miniature lockset that is applied to e-machine that a kind of volume is little, simple in structure, cost is low.

Of the present utility model time a purpose is to design a kind of a kind of miniature lockset that is applied to e-machine that needs through the unlocking action of vertically-acting and horizontal balance.

The technological means that the utility model is dealt with problems is: a kind of miniature lockset that is applied to e-machine is provided, it is to be combined by lock housing, turn core, elastic parts and fixture, wherein: this lock housing has the inner chamber of hollow, inner chamber is provided with a fixture block, on lock housing, be provided with a stopper section and a fixing hole, and this stop portion has a perforate; This turn core is inserted in the inner chamber of lock housing, and the top of this turn core has a spacing hole, and the peripheral part has second groove of first groove and contiguous this first groove; And this fixture has a fixing hole; Use the Lower Half of in regular turn this elastic parts being inserted in the turn core, this fixture is placed in turn core Lower Half again and is arranged between turn core and the lock housing, both are fixed by fixing hole with lock housing and fixture to see through a latches, the turn core is limited in the inner chamber of lock housing, and elastic parts is limited between turn core and the fixture.

Wherein, under the turn core tongue piece can be set.

Both fix with lock housing and fixture to see through a latches, the turn core is limited in the inner chamber of lock housing, use and apply a power to the turn core, this turn core is stressed to press down and can accept to rotate power simultaneously snapped-in position is changed, and form to buckle by the reaction force of elastic parts and hold effect, tongue piece change in location below so this turn core can drive, carry out the work of bolt-lock or unlatching with other mechanism's collocation when rotating.

By above-mentioned technological means, the volume of lockset can be utilized core and lock housing concentric type to wear and contracts to minimum, and the turn core carries out the snapped-in position variation, the simple and low usefulness of cost of the structure of signing an undertaking; Moreover, by above-mentioned feature, can be applicable to various computers, e-machine equipment, and then its snap close usefulness is provided.

Below will cooperate graphic explanation preferred embodiment of the present utility model; following cited embodiment is only in order to illustrate the utility model; be not in order to limit scope of the present utility model; anyly have the knack of this skill person; when doing a little change and retouching, therefore protection domain of the present utility model is as the criterion when looking the claim person of defining.
