The utility model adopts a reasonable complex structure, therefore the whole lock is compact and safe. The utility model is an ideal lock of a door lock.

Description

A kind of stealthy lock gall tapered end

Technical field

The utility model belongs to door lock, is specifically related to the tapered end of door lock.

Background technology

The present door lock that uses, the problem majority appears at tapered end, and reason is that lock body structure is simple, and each lock body is independent, does not correlate mutually, adds to use for many years conventional process techniques to be understood by people deeply, uses simple tool, just can unblank the poor safety performance of tapered end.

Summary of the invention

The purpose of this utility model just provides a kind of complex structure, safe and reliable door lock.

The utility model comprises the tapered end shell structure, two stealthy built-in front and back lock gall structures, anterior-posterior balance formula lock body combining structure, ten anterior-posterior balance formula lock body combinations, pentagon two layout layer structures behind the pentagon before being divided into, and five jiaos of type keys, convex body obstacle construction in the post lock core.

The utility model adopts two stealthy built-in front and back lock gall structures, characteristics one owing to one. and lock gall be cannot see in the tapered end outside, and the lock gall that is subjected to the protection of tapered end shell is not easy to go to pot.Characteristics two are motionless owing to the tapered end shell, and lock gall will rotate, and key is proposed special requirement, and key enters in the tapered end, has tapered end shell position key diameter little, and the lock gall position is arranged, and it is big that the key diameter is wanted, and key could not be obstructed and drive the lock gall rotation, strengthens technical difficulty.Two adopt anterior-posterior balance formula lock body combining structure, and characteristics one front and back linkage interacts, and does not use first wife's key to be difficult to accomplish anterior-posterior balance.Characteristics two lock dog locking face areas are big, the stability of favourable reinforcement tapered end.Three adopt ten anterior-posterior balance formula lock body combinations, pentagon two layout layer structures behind the pentagon before being divided into, and characteristics are complicated, make a confined space become the situation that balance is all wanted in comprehensive front and back up and down, use the other technologies method to unblank extremely difficult.Four adopt convex body obstacle construction in the post lock core, and characteristics stop does not have recess or the not right object of recess direction to enter, and increases technical difficulty again.A plurality of textural associations make the complex structure of tapered end together, compactness, and rationally, safety is more guaranteed, is a kind of desirable door lock.

Most preferred embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises the tapered end shell structure, two stealthy built-in front and back lock gall structures, anterior-posterior balance formula lock body combining structure, ten anterior-posterior balance formula lock body combinations, pentagon two layout layer structures behind the pentagon before being divided into, and five jiaos of type keys, the obstacle construction of post lock core convex body.Wherein built-in anterior lock core 3 post lock cores 4 are placed in tapered end shell 1, in the middle case 2, are protected, and are not easy to go to pot.Ten anterior-posterior balance formula lock body combinations, the lock dog groove of pentagon 19 back pentagon 20 layouts before being placed in respectively.Wherein the stacker 8 in the lock dog groove 15 is accepted preceding lock dog 9 recess 16 down, last lock dog 10, and spring 11 is formed the lock bodies combination.Lock dog 10 is subjected to spring 11 pressure horizontal in tapered end shell 1 and anterior lock core 3 on the static state, middle case 2, and between the post lock core breach 5, two lock galls before and after pinning do not allow its rotation.Dynamically under first wife's key 21 effect, by the position, height top 17 of lock dog 9 down, position, low top 18 will be gone up lock dog 10 and be pushed back tapered end shell 1 position, and the tapered end shell separates with lock gall, and other lock body work in combination principles are the same.Twist key 21 anterior lock cores 3 post lock cores 4 again and rotate,, thereby finish the switch door lock process by connection iron block 7 switch door locks.Convex body 6 obstacle constructions are to stop not have recess or the not right object of recessed direction to enter in the back institute courage 4.
