Description

Pick-proof lock

The utility model relates to a kind of lockset, specifically a kind of pick-proof lock.

Lockset kind in the market is a lot, and style is more complete, comprises various security door.These locksets all are made up of lock housing, lock core, spring, pin etc. basically, and are simple in structure, but safety this is relatively poor, pried open easily.Also some is made up of two or more sets lock cores, vi have high safety, but it must use inconvenient by two or many key unlocking.

The purpose of this utility model is exactly in order to overcome above-mentioned the deficiencies in the prior art, provides a kind of and is made up of multi lock core, but only use a key unlocking, and is simple in structure, vi have high safety, pick-proof lock easy to use.

For achieving the above object, a kind of pick-proof lock of the utility model, it is made up of lock housing, lock core, pin, spring and key, lock core is installed in the lock housing, it is characterized in that lock core is made up of forward and backward two parts, establish trough with straight angle near anterior lock core place in the two-part pin-and-hole certain angle that staggers, rear section lock core, spring is positioned at trough with straight angle.

The utility model is simple in structure, and is easy to use, and vi have high safety is safe and reliable.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the local figure of first segment lock core.

Fig. 3 is the local figure of the second joint lock core.

As can be seen from Figure 1, a kind of pick-proof lock of the utility model, it is made up of lock core 1, lock core 2, lock housing 3, pin-and-hole 4, spring 5 and pin etc.Lock core 1 and lock core 2 are installed in the lock housing 3, and lock core 1, lock core 2 forward and backward connections cooperatively interact, and they form lock core jointly.And lock core 1 can rotate with respect to lock core 2.The pin-and-holes certain angle that staggers of two joints, the angle that the pin-and-holes of two joints stagger are no more than 90 degree, as shown in Figures 2 and 3.Lock core 1 and lock core 2 are matched in clearance with the lock housing stepped hole.Pin is positioned at pin-and-hole 4, among the figure on the opposite direction lock housing of B-B arrow every interval 45 degree pin-and-hole is just arranged, as shown in Figure 2.Among the figure on the direction lock housing of B-B arrow every interval 90 degree pin-and-hole is just arranged, as shown in Figure 3.Cotter way is established at the rear portion of

lock core

2,2 one weeks of cotter way ring lock core, establish alignment pin in the cotter way, and play fixed lock core.Establish trough with straight angle near lock core 1 place in the lock core 2, spring 5 is positioned at the trough with straight angle of lock core 2, and it is set on the cylinder of lock core 2, and two terminations of spring 5 are other respectively in trough with straight angle and on the cylinder of lock core 1, play automatically reset effect.During installation, adorn lock core 1 earlier in lock housing, back shock mount 5 and lock core 2 add pin again, the sealing lock housing.

When the utility model uses, key is inserted lockhole, reverse lock core 1 certain angle, overlap to the lockhole of core 1 with lock core 2, the lockhole of the lock core 2 of exerting oneself key is inserted again reverses lock core together, can open door.

The utility model simple structure, cost is low, and is easy to use, safe and reliable.

Claims

1. pick-proof lock, it is made up of lock housing, lock core, pin, spring and key, and lock core is contained in the lock housing, it is characterized in that lock core is made up of forward and backward two parts, establish trough with straight angle near anterior lock core place in the two-part pin-and-hole certain angle that staggers, rear section lock core, spring is positioned at trough with straight angle.

2. pick-proof lock according to claim 1 is characterized in that the angle of the forward and backward two parts pin-and-hole of said lock core is spent less than 90 greater than 0 degree.
