Description

Has the anti-safety lock of pushing function aside

Technical field

The utility model relates to a kind of five metals lockset, and especially a kind of have an anti-safety lock of pushing function aside.

Background technology

Existing five metals lockset kind and type are varied, padlock is arranged, bicycle lock, chain lock, door lock etc., though these lockset profile sizes have nothing in common with each other, but the form of structure of part such as its core component lock core is unanimous on the whole, the weak point of these locksets is that the pellet shot from a slingshot in the lock core can be pushed up whole pellet shot from a slingshot holes from lock core in the pellet shot from a slingshot hole on the lock body, thereby lock is opened, this is that the people that repaiies the lock bitting gives and to lose the key a kind of universal method that the people of lock unblanks of not opening, and this universal method causes opportunity may for the lock tool that pulls out of lawless person's configure generic, this general pock-poking tool can completely be pushed many locks of same kind same model aside, and this will cause factor leading to social instability to society.

The utility model content

The purpose of this utility model is in order to overcome the anti-shortcoming of dialling poor performance of existing lockset, a kind of anti-safety lock of pushing function aside that has to be provided.

The purpose of this utility model realizes as follows:

Develop a kind of anti-safety lock of pushing function aside that has, comprise the lock core in the lock body, on lock body and the lock core corresponding pellet shot from a slingshot hole with and interior pellet shot from a slingshot and spring, it is characterized in that the length of pellet shot from a slingshot hole inner spring after compacted adds that the length summation of all pellets shot from a slingshot in this pellet shot from a slingshot hole is greater than the hole depth length that is positioned at the corresponding pellet shot from a slingshot of lock body part hole.

It is provided with in lock body under the situation in a plurality of pellets shot from a slingshot hole, can only set wherein spring in any one or the several pellets shot from a slingshot hole length after compacted and add that the length summation in this pellet shot from a slingshot hole is greater than the hole depth length that is positioned at the corresponding pellet shot from a slingshot of lock body part hole.

The advantage that the utility model provides is:

Because the length after pellet shot from a slingshot hole inner spring is compacted adds the hole depth length of the length summation of all pellets shot from a slingshot in this pellet shot from a slingshot hole greater than this pellet shot from a slingshot hole lock body part; Therefore the pellet shot from a slingshot in this pellet shot from a slingshot hole can break away from the pellet shot from a slingshot hole on the lock core in no instance, just can't carry out the mode of unblanking that all pellets shot from a slingshot all are pressed in the pellet shot from a slingshot hole on the lock body with preceding described general pock-poking tool; In a lock, have under the situation in several pellet shot from a slingshot holes, as long as one of them pellet shot from a slingshot hole is this frame mode, this lock has just possessed the anti-function of pushing aside, so promptly do not influence and unblank with private key, strengthened the safety of this lock again, also do not need the original structure of lock is done big change, have bigger use value.

Description of drawings

Fig. 1 is an internal construction schematic diagram of the present utility model;

Fig. 2 is the general pock-poking tool mode schematic diagram of unblanking;

Fig. 3 is the private key mode schematic diagram of unblanking.

The specific embodiment:

In Fig. 1, lock core 8 is housed in the lock body 1, be provided with 4 pellet shot from a slingshot holes in the lock altogether, each the pellet shot from a slingshot hole 2 on the lock body 1 and each the pellet shot from a slingshot hole 6 on the lock core 8 are with one heart corresponding one by one, long marble 4 in the pellet shot from a slingshot hole and short pellet shot from a slingshot 5 can be under the effect of spring move left and right; Spring shown in Fig. 1 is compacted contraction state, this moment, compacted spring 3 added the hole depth length of the length summation of long marble 4 and short pellet shot from a slingshot 5 greater than the pellet shot from a slingshot hole 2 on the lock body 1, just the short pellet shot from a slingshot 5 on the left side can't continue move right, can only be positioned at pellet shot from a slingshot hole 6 on the lock core 8 with a general end that pulls out lock tool 7 contacted short pellets shot from a slingshot 5, since general pock-poking tool 7 only all pellets shot from a slingshot are whole in will lock be pressed into corresponding pellet shot from a slingshot hole 2 on the lock body 1 from the pellet shot from a slingshot hole 6 of lock core simultaneously in, could open by 8 locks of rotational lock core, therefore the general tool of exchanging work has lost effect under the said structure form of safety lock, can't open this lock.This lock that includes several pellet shot from a slingshot holes, as long as wherein the summation of length that compacted spring length adds all pellets shot from a slingshot in any one or the several pellets shot from a slingshot hole is greater than the hole depth length in pellet shot from a slingshot hole on the lock body, this lock just can not be opened by this general group of lockset instrument 7.

The general pock-poking tool 7 of usefulness shown in Figure 2 is opened when having common lock now, the inner pellet shot from a slingshot position view of this lock, its basic principle is in the pellet shot from a slingshot hole 2 that will be extruded into the whole pellet shot from a slingshot holes 6 from lock core simultaneously of pellet shot from a slingshot on the lock body when unblanking with this pock-poking tool, make pellet shot from a slingshot lose inhibition, rotational lock core is opened lock then.

Shown in Figure 3 is that private key 9 is when unblanking, this lock external morphology schematic diagram, the basic principle that private key 9 is unblanked is that the contact surface between pellet shot from a slingshot or the end face of pellet shot from a slingshot are aligned on the contact surface of lock body and lock core simultaneously, thereby lock core can be rotated in lock body and opens lock.This mode of unblanking is the existing mode of unblanking, and also is applicable to the mode of unblanking of the present utility model.
