Description

Mechanical lock

Technical field

The utility model relates to a kind of mechanical lock, particularly a kind of mechanical theft proof padlock.

Background technology

General lockset is all used key operated; If but key is lost or is forgotten to take with oneself and just need ask the locksmith to unblank; So combination lock do not need key operated just can open still to grasp to do do not have the convenience of key range of application comparatively limited; The similar functions product can only be used key operated door lock in addition, is resetting number behind the door with hand switch then, and its design is not suitable for the requirement of small-sized locksets such as padlock or automobile anti-theft lock.

Summary of the invention

The main purpose of the utility model provides a kind of mechanical lock, is intended to realize the combination lock function is incorporated on the lock core, with under normal conditions, uses key operatedly, when having key, does not just open with combination lock, can increase the convenience that lockset is operated like this.

The utility model proposes a kind of mechanical lock, and it comprises a lock body, and a lock shaft is with sealing or open the space between lock shaft and lock body; With a lock core, be used for guiding and hold a key, said key gets into said lock core and locks or opening function with completion to drive said lock shaft; Said mechanical lock also comprises a cipher code set; With an extraction and a dead bolt of controlling said lock shaft, control the extraction action of said lock shaft to cooperate said cipher code set.

Preferably, said dead bolt also comprises a dead bolt driving shaft, to drive said dead bolt and said lock shaft and a latch bolt spring and the acting in conjunction of said dead bolt driving shaft to drive said dead bolt.

Preferably, said mechanical lock also comprises a lock core spline sheet group, and with the rotation of control lock core, said key is controlled the position of said lock core spline sheet and reversed said lock core, and the action of the said lock core of transmission is to said lock shaft.

Preferably, said mechanical lock comprises driving shaft distribution, and to promote said dead bolt driving shaft, a driving shaft spring is to drive a dead bolt driving shaft and a driving shaft latch, to limit the twitch of said dead bolt driving shaft.

Preferably,, said lock core is provided with a lock core steady pin, and with fixing said lock core, said lock shaft is provided with lock shaft sealing piece, to seal a said lock body bottom end opening and a lock shaft steady pin, with fixing said lock shaft.

Preferably, said lock shaft is the J type.

Preferably, said mechanical lock also comprises a location steel ball and a location spring, so that said lock core anglec of rotation location.

The beneficial effect of the utility model is; Only utilize a simple slide block to come the transmission dead bolt just can obtain required function, because simple for structure, the volume demand is little; Be easy to be applied to picture padlock or baggage compartment lock, the lock class application facet that bin drawer-lock equal-volume is less.

The specific embodiment

Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Referring to figs. 1 through Fig. 5, propose the utility model the mechanical lock of an embodiment, said mechanical lock comprises lock body 1, to hold and to protect other spare parts, lock shaft 2; Preferably, said lock shaft 2 is the J type, to seal or to open the space of 1 of lock shaft 2 and lock body, a cipher code set 3; 4,5,6, with the extraction of control lock shaft 2; One lock core 7 is used for guiding and holds key 23, and said key 23 gets into said lock core 7 and drives a said lock shaft 2 and a dead bolt 12; Control the extraction action of lock shaft 2 to cooperate cipher code set 3,4,5,6.

Said mechanical lock also comprises a lock core

spline sheet group

8,9,10,11, with the rotation of control lock core 7.Said dead bolt 12 also comprises a dead bolt driving shaft 13, to drive dead bolt 12 and lock shaft 2 and a latch bolt spring 14 and said dead bolt driving shaft 13 actings in conjunction to drive said dead bolt 12.Especially, said mechanical lock comprises driving shaft distribution 19, to promote said dead bolt driving shaft 13, one driving shaft springs 15, to drive a dead bolt driving shaft 13 and a driving shaft latch 20, with the twitch of restriction dead bolt driving shaft 13.Said lock core 7 is provided with a lock core steady pin 17, and with fixing said lock core 7, said lock shaft 2 is provided with lock shaft sealing piece 16, with sealing lock body 1 bottom end opening and a lock shaft steady pin 18, with fixing said lock shaft 2.In addition, said mechanical lock also comprises a location steel ball 21 and a location spring 22, so that said lock core 7 anglecs of rotation location.Lock core 7 is also reversed in the position of the said lock

core spline sheet

8,9,10,11 of said key 23 controls, and transmission lock core 7 moves on the lock shaft 2.

When using; As shown in Figure 2, key 23 to be inserted lock cores 7 and begins to direction of arrow rotary locking cylinder 7, driving shaft was promoted 19 and can be promoted dead bolt driving shaft 13 earlier and move to the direction of arrow this moment; When driving shaft distribution 19 begins to move; Shown in partial enlarged drawing, dead bolt driving shaft 13 meeting compressible drive axle springs 15, and the guiding of the dead bolt on the dead bolt driving shaft 13 hypotenuse will push away the top margin that contacts dead bolt 12 upper end grooves and make dead bolt 12 in the direction of arrow moves the dead bolt holding tank on the retraction lock shaft 2.

As shown in Figure 3; Because dead bolt 12 has been retracted in the lock shaft 2, and though when continuing rotary locking cylinder 7 again the cipher code set correct position whether lock shaft all can be by transmission, as shown in Figure 4; And the short end of lock shaft 2-1 is pushed out of the lock shaft locating slot 1-1 outside on the lock body 1, just can rotate freely lock shaft 2 then.The group 3 if forget Password; During 4,5,6 correct numbers; At this moment can be one by one or rotate other cipher code set simultaneously; Dead bolt 12 will fall in the control breach when the control breach aligns dead bolt 12 on the cipher code set, when all dead bolts 12 all fall into the control breach on the cipher code set, just can recover original setting number.

With reference to Fig. 5, when when using key to come locking, moving, lock core 7 is gone back to original position extract key 23 then out.Rotating lock shaft 2 then is pressed into the lock shaft locating slot 1-1 that the short end of lock shaft 2-1 aligns on the lock body in the lock body 1 with lock shaft 2 then; This moment, all dead bolts 12 can be pushed out of outside the dead bolt holding tank on the lock shaft 2 by latch bolt spring 14; In order to interfere cipher code set 3; 4,5,6 to prevent that lock shaft 2 is drawn out outside lock body 1.When the group that accesses to your password is unblanked, forward all cipher code set 3,4,5,6 to tram, the control breach on the cipher code set has all corresponded to dead bolt 12 positions at this moment.With regard to the available lock shaft 2 that pulls out, make the short end of lock shaft 2-1 break away from the lock shaft locating slot 1-1 on the lock body, just can rotate freely lock shaft 2.This moment is because all dead bolts 12 all fall into cipher code set 3,4, in the control breach on 5,6, so all cipher code set 3,4,5,6 all can be followed rotation during rotation lock shaft 2, to keep original number of setting.When the group that accesses to your password was come locking, rotation lock shaft 2 aligned the lock shaft locating slot 1-1 on the lock body 1 with the short end of lock shaft 2-1, just can the short end of lock shaft 2-1 be pushed in the lock shaft locating slot 1-1 on the lock body 1; Rotate all cipher code set 3,4,5 this moment more arbitrarily; 6 make cipher code set 3; On 4,5,6 the control breach not all align dead bolt 12 just can prevent that the short end of lock shaft 2-1 is drawn out outside the lock shaft locating slot 1-1 on lock body 1.

The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure transformation that utilizes the utility model manual and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
