Description

Card lock

Technical field

The utility model relates to a kind of lock, refer to a kind of card lock especially with the polynary combination of multistage.

Background technology

Along with being showing improvement or progress day by day of science and technology, industry and commerce sharply develops, and all kinds of now commodity are to spend all pains under the double condition that can meet and adapt to the modern and pursue visual sense of beauty and practical value invariably; Existing lock structure, it is mainly by being provided with a blocking mechanism in the lock body, and be provided with lockhole in lock body, can insert to make blocking mechanism produce the effect of opening or closing for key, promptly constitute a lockset according to this, though yet such lock structure can reach the effect of locking, but lack variability owing to lock structure is comparatively simple and easy, easy problem because of intercommunity, and only need hold key or other instruments (such as objects such as iron wire or yi word pattern screwdrivers) of similar lockset, promptly can pry open lock body, reach the purpose of unblanking, therefore cause its safety obviously to reduce, how to research and develop one and have polynary locking, and the lock structure that is difficult for being opened by other or similar key is the important topic that modern enterprise institute utmost point desire solves; Therefore, the card lock of many passwords arises at the historic moment.

In view of existing lock structure still has above-mentioned shortcoming,, generation of the present utility model is arranged finally so the utility model creator at its shortcoming, grinds improvement deeply.

Summary of the invention

The utility model main purpose is promptly providing a kind of card lock, be used to solve that prior art exists is simple in structure, lack change, shortcoming that security performance is low.The purpose of this utility model is achieved in that it comprises: part such as lock body, locking unit and blocking element constitutes; Wherein being provided with content space in the lock body can be for above-mentioned locking unit and blocking element are set, and the one end is provided with can be for the insertion mouth of password card insertion, the top then is provided with opening, above-mentioned locking unit has vertically by one and drive block and some prominent keys that is installed in this hole in horizontal hole are formed, and an end of this drive block is set as inclined plane shape, one end of its body of blocking element stretches outside the opening of above-mentioned lock body, and two epitaxial lateral overgrowths are stretched support arm, this support arm is provided with corresponding guiding incline towards the place, inclined-plane of drive block, and be provided with flexible member between support arm below and the content space, by the combinations thereof device, can form a card lock; This kind card lock structure can be provided with difference by its vertically compound high and low position of laterally dashing forward key, makes it have polynary permutation and combination method, makes it to have the characteristic that a multistage locking changes.

Compared with prior art the utility model has the advantages that: adopt the lock structure different with the existing machinery lockset, by adjusting the combination of allocating the prominent key of different types in the drive block hole into, and by controlling the difference that height be set of this laterally prominent key lug in groove, the variation that permutation and combination that can more polynary multistage goes out different locking passwords, avoid many common problems of key, therefore have excellent locking effect.

The specific embodiment

As shown in Figure 1 and Figure 2, can find out that by diagram the utility model mainly comprises: major parts such as lock body 1, locking unit 2, blocking element 3 and card 4 constitute; Wherein lock body 1 constitutes a box-like housing by upper and lower cover body 11,12, these lock body 1 one ends are provided with an insertion mouth 13 and can insert for password card 4, and the inner content space 10 that is provided with can be for being installed with above-mentioned locking unit 2 and blocking element 3, loam cake 11 offers an opening 14 in the appropriate position in addition, 12 both sides in content space 10 of lower cover are provided with groove 15, can stretch into blocking stretched by card 4 to push to move for the lug 231 of the prominent key 23 of aftermentioned;

Above-mentioned locking unit 2 is by a drive block 21 and some vertical or horizontal prominent keys 22 of fixing or elasticity, 23 form, wherein drive block 21 is provided with some have vertical and horizontal guide grooves 241,251 hole 24,25, in order to hold to go into above-mentioned prominent key 22,23, and from the inboard flange 26 that outwards upwards extends inclined-plane 261 of at least one end, above-mentioned prominent key 22,23 its tops can be provided with and movably push away face 223,232 reach the face 222 that movably do not push away, and side can extend lug 221,231, make prominent key 22,23 hold to go into hole 24,25 o'clock, the sliding respectively guide groove 241 that is embedded in, 251, and the key 22 of should dashing forward, 23 at least the bottom of one be provided with flexible member 27 support, make it can be in this hole 24, produce springing in 25, be located at the laterally prominent key 23 in horizontal guide groove 251 holes 25, its lug 231 is stretched at outside the guide groove 251, and can be when being subjected to pressing down, elasticity moves down embedding and stretches in the embedding systems that produce in the groove 15 of above-mentioned lower cover 12, causes the drive block 21 can't be towards lateral displacement in the lock body 1; Otherwise if lug 231 is not displaced downwardly in the groove 15, then drive block 21 has towards lock body 1 interior traversing ability;

Blocking element 3 is installed in the content space 10 of above-mentioned lock body 1, and with locking unit 2 adjacent installings, the one end is provided with the lock end 31 of pulling and can be upwards stretches out from the opening 14 of loam cake 11, and two epitaxial lateral overgrowths of nearly bottom are provided with support arm 32, these support arm 32 correspondences are set as guiding incline 33 towards 261 places, inclined-plane of drive block 21, and are provided with flexible member 34 elasticity supports in addition between support arm 32 belows and content space 10 bottoms; According to the combinations thereof device, can form card lock;

When unblanking, still need and insert mouthful 13 insertions towards lock body 1 by an above-mentioned password card 4 with some proper password holes 41, make the 41 pairs of positive controls of hole on the card 4 produce a setting displacement action by prominent key 22,23, make this drive block 21 when the password correspondence is correct, can agree to the action that pushes of card 4 in lock body 1, to produce horizontal movement again, can make guiding incline 33 on blocking element 3 support arms 32 be subjected to inclined-plane 261 to promote guiding by this horizontal movement and move down, even so the lock end 31 of pulling contracts in the lock body 1 synchronously and produces a unlocking action; Otherwise, when card 4 from inserting mouthfuls 13 when detaching, blocking element 3 breaks away from compressing of drive blocks 21, and is subjected to top on its flexible member 34, and then recover the locking state, the flexible member 27 1 that prominent key 22,23 also is subjected to its bottom upwards roof pressure elastic force and return to original state.

Comprehensive the above as can be known, the card lock structure that the utility model relates to has the locking permutation and combination variation characteristic of polynary multistage really, produces excellent locking effect thus.
