Abstract

The present invention discloses one kind of anti-theft ball lock, and is especially one kind of anti-theft ball lock core with increased ball seats and ball holes and unique ball arranging mode and matched comb-shaped key. The anti-theft ball lock has hidden built-in ball lock core is convenient and safe, has simple structure, unique anti-theft function and high performance/cost ratio.

Description

Concealed built-in cylinder anti-theft lock end

Technical field

The present invention relates to anti-theft cylinder lock, specifically relate to the built-in cylinder anti-theft lock end of a kind of secret.

Background technology

Lock is the necessity during people live, and social at present upward robber picking lock phenomenon is very serious, and the protective effect of lock is more and more lower, though present lock kind is more, anti-theft feature is generally relatively poor, and common thief or the specialty person of unblanking are performed practically no function.

Summary of the invention

Purpose of the present invention just is to overcome the existing defective that is latched in and the deficiency of anti-theft feature difference, and provides a kind of secret built-in cylinder anti-theft lock end, and safety during use is relieved, convenient, insurance.

The object of the present invention is achieved like this, promptly on the lock core of existing tapered end, increase the intercommunicating pore of pellet shot from a slingshot cylinder bottom seat and pellet shot from a slingshot cylinder and key hole slot, adopt the aligning method of concealed built-in pellet shot from a slingshot, make on the pellet shot from a slingshot and move, be equipped with brand-new broach shape key, form a complete concealed built-in cylinder anti-theft lock end.

The present invention has the following advantages:

(1) lock core is employed new technology has increased pellet shot from a slingshot cylinder bottom seat and pellet shot from a slingshot cylinder and key hole slot intercommunicating pore between key hole slot and pellet shot from a slingshot cylinder, in the pellet shot from a slingshot cylinder pellet shot from a slingshot is housed, pellet shot from a slingshot adopts the strong tack pellet shot from a slingshot of theftproof performance, abandon traditional tip pellet shot from a slingshot, pellet shot from a slingshot is hidden on the pellet shot from a slingshot cylinder bottom seat, and just cannot see from the key hole slot and also can't bump pellet shot from a slingshot, not supporting key, think that pirate of the open is difficult to, thereby guaranteed the theftproof performance and the safety effect of lock.

(2) supporting key is novel unique, when broach shape key bit inserts the key hole slot, the shank of the key is continued to push inward, effect sliding block alignment pin motion forward in slide block alignment pin stroke track in external force, slip apical tooth piece enters the key hole slot, it is up to head on broach shape key bit, enter pellet shot from a slingshot cylinder and key hole slot intercommunicating pore, the motion of key bit pushing tow pellet shot from a slingshot, the pellet shot from a slingshot top pressure spring shrinks, make pellet shot from a slingshot move to opening, the key handle, lock core and power transmission shaft rotate simultaneously, reach the purpose of unblanking and locking, it is very convenient to operate, insurance.

(3) simple in structure, advanced rationally, special anti-theft feature, novelty, the cost performance height is applicable to the lockset of any purposes.

The specific embodiment

Describe in detail below in conjunction with drawings and Examples

As shown in Figure 1, the lock core assembly is made up of lock core 1 and pellet shot from a slingshot 4 two parts, key hole slot 2 is arranged on the lock core 1, pellet shot from a slingshot cylinder 3, pellet shot from a slingshot cylinder bottom seat 5, pellet shot from a slingshot cylinder and key hole slot intercommunicating pore 6, lock core and power transmission shaft locating groove 7, power transmission shaft locating slot 8 is equipped with pellet shot from a slingshot 4 in the pellet shot from a slingshot cylinder 3, pellet shot from a slingshot 4 is built on the pellet shot from a slingshot cylinder bottom seat 5.Pellet shot from a slingshot cylinder and key hole slot intercommunicating pore 6 are isolated the secret of protection pellet shot from a slingshot 4 pellet shot from a slingshot 4 and key hole slot 2 middle formation.

As shown in Figure 2, key is by broach shape key bit 9, and slide block back-moving spring 13 and the shank of the key 14 are formed, and the afterbody of broach shape key denticle 9 has the stroke track 11 of slide block alignment pin 12 and the socket of spring 13; Slip apical tooth piece 10 is arranged, the socket of slide block alignment pin 12 and spring 13 on the shank of the key 14.

Fig. 3 is the embodiment of the invention, as shown in Figure 3, when Fig. 1 lock core assembly is installed in the tapered end 18, load onto the fixing card 16 of power transmission shaft 15 and lock core and power transmission shaft, refill pellet shot from a slingshot and pellet shot from a slingshot top pressure spring 17, promptly form concealed built-in cylinder anti-theft lock end, when Fig. 2 broach shape key bit 9 inserted key hole slot 2, pellet shot from a slingshot 4 was built on the pellet shot from a slingshot cylinder bottom seat 5, because of the isolation of pellet shot from a slingshot cylinder and key hole slot intercommunicating pore 6, broach shape key bit 9 just bumps less than pellet shot from a slingshot 4, at this moment the shank of the key 14 should be continued to push inward, under the effect of power, slide block alignment pin 12 is motion forward in slide block alignment pin stroke track 11, slip apical tooth piece 10 enters key hole slot 2, it is up to head on broach shape key bit 9, enters pellet shot from a slingshot cylinder and key hole slot intercommunicating

pore

6,4 motions of broach shape key bit 9 pushing tow pellets shot from a slingshot, pellet shot from a slingshot top pressure spring 17 shrinks, make pellet shot from a slingshot 4 move to opening, key handle 14, lock core assembly and power transmission shaft 15, in tapered end 18, rotate simultaneously, reach the purpose of unblanking and locking.Unblank or after the work of locking finishes, hand unclamps the shank of the key 14, under the effect of slide block back-moving spring 13, slip apical tooth piece 10 and slide block alignment pin 12, automatically get back to state before the work along slide block alignment pin stroke track 11, just can easily key be withdrawed from from key hole slot 2, it is very convenient to operate, insurance.
