Description
Technical field
The utility model relates to a kind of theftproof lock.
Background technology
At present, existing lockset generally adopts a hole one pin design, and the lockset of this design can be unblanked easily by modes such as chewing gum method, lash methods, and the lockset key density of this kind structure is little simultaneously, the spoonful phenomenons of opening of ubiquity more, and safety is relatively poor.
The utility model content
The purpose of this utility model is to provide a kind of peaceful property high theftproof lock.
The purpose of this utility model is achieved through the following channels: a kind of theftproof lock, comprise lock body and key, lock body inside is provided with lock core and spring eye, last lock pin in the lock pin is positioned at lockpin hole, its top and key hole constitute the key groove jointly, following lock pin in the lock pin is positioned at spring eye, and the following lock pin bottom in the lock pin is provided with spring, and lock body inside is equipped with two different lengths and is close to lock pin arranged side by side.The bar shaped of the lock pin side of being, lockpin hole also are square frame shape.The length of the last lock pin in the lock pin is greater than 2/3rds diameters of lock core.
A kind of theftproof lock of the utility model, it comprises lock body, lock core, lock pin, key, by lock pin diverse location in pin-and-hole realize unblanking, blocking function.Different with general traditional cylinder lock is the novel unique texture that adopts hole multi-pin.Pin-and-hole is square, and lock pin is longer, is more than 2/3rds of lock core diameter, and section is rectangle, and structurally restriction can not all eject lock core with going up lock pin, thereby avoids chewing gum, gas method to unblank.Going up of two different length is housed in the pin-and-hole sells and downside pin, two lock the mutual friction of subsides phase, have avoided hammering method, lash method to unblank.Do not having under the spoon state, the left and right pin of going up pushes up under spring thrust to lock body core internal surface of hole, in the spoon groove and do not have and pull out the tooth space, can avoid pulling out the tooth method and unblank.This utility model structure key density is big, can reach more than 20 ten thousand kinds of combinations, spoonfully opens phenomenon more, and is almost nil.
The utility model is simple in structure, dependable performance, key density is big, theftproof performance good, can stop prior art when using unblanks.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation.
The specific embodiment
As shown in Figure 1, a kind of theftproof lock of the utility model, comprise lock body 4 and key, lock body 4 inside are provided with lock core 1 and spring eye 6, and the last lock pin in the lock pin 7 is positioned at lockpin hole 3, its top and key hole 8 common formation key grooves 2, following lock pin in the lock pin 7 is positioned at spring eye 6, and the following lock pin bottom in the lock pin 7 is provided with spring 5, and lock body 4 inside are equipped with two different lengths and are close to lock pin arranged side by side 7, lock pin 7 sides of being bar shaped, lockpin hole 3 also are square frame shape.The length of the last lock pin in the lock pin 7 is greater than 2/3rds diameters of lock core 1.
Be the course of work of the utility model theftproof lock below: when key inserts lock core 1, under the promotion of spring 5, when last lock pin in the lock pin 7 and key bit coincide, when last lock pin lower surface and lock core 1 external cylindrical surface are contour, lock core 1 can rotate, and theftproof lock is opening; When key was extracted out, under the promotion of spring 5, two following lock pins were gone up the lock pin ejection to contacting lock body 2 core internal surface of hole with two respectively, and two following lock pins in the lock pin 7 insert in the lock core 5, tie down lock core 1, and lock core 1 can not rotate, and theftproof lock is locking states; When key bit is misfitted, go up the lock pin lower surface with lock core 5 external cylindrical surfaces when not contour for two, will occur left and rightly going up lock pin or the left and right lock pin that plays tacks lock core 1 phenomenon, lock core 1 can not rotate, and theftproof lock is locking states.
