It is equipped with billiard mechanism, the lockhole is warp architecture, and the warp architecture includes straight portion's chamber and bending section chamber, the billiard mechanism
It is arranged in the cavity wall of straight portion's chamber.
Preferably, the outer end of the plug body is provided with rotation protection handle, rotation protection handle be provided with and
The corresponding keyhole of lockhole, the rotation protection handle are set to the outer end of plug body, the connection card by connects bayonet socket
Mouth can bear fixed power.
Preferably, the connects bayonet socket include be arranged plug body spring and be set to rotation protection handle and lock core
Hoodle between ontology.
The invention also discloses a kind of key with the cooperation of theft-preventing mechanical lock lock core, including key body, the keys
Spoon ontology includes flexible portion and the rigid portion arranged at the bottom being arranged in outer end, and the rigid portion extends to the bending of lockhole
Portion's chamber.
Preferably, the flexible portion is made of bendable material, and the rigid portion is made of rigid material.
The utility model discloses a kind of theft-preventing mechanical lock, including lock body again, and the lock body includes the anti-of the utility model
Steal mechanical lock core.
Preferably, the lock body is installed on doorframe, and the lock core outer incline is provided with bend limiting holes, the bend limitation
Hole includes arm extending portion and bend portion, and the bend portion covers lock core, and the diameter of the arm extending portion is slightly larger than arm
Diameter.
Compared with prior art, the utility model has the advantages that：
1, lock core is arranged on doorframe, is provided with singlehanded turning hole, in addition one hand turning hole limits illegal unlock
The use of one hand, turning increase visual difficulty and operation firmly difficulty, avoid illegal unlock again；Because having outside doorframe enough
Space, so cylinder design can allow the volume change of lock more to have development space, and strength failure on the door on doorframe
It is minimum.
2, the design of bend lock cylinder keyhole can effectively stop the illegal entrance of rigidity unlocking tool, if with flexible material
Material illegally enters the variation that can not just accurately control tool；If with brute-force rotary locking cylinder, rotation protection handle automatically disengages lock
Core dallies, and efficiently solves the method that brute-force rotation is unlocked.
3, the flexible key hook that soft scleroma is closed is effectively reduced weight and metal bump sound with human body, conveniently takes
Band.

Specific implementation mode
To make the objectives, technical solutions and advantages of the present invention clearer, With reference to embodiment
And with reference to attached drawing, the utility model is further described.It should be understood that these descriptions are merely illustrative, and do not really want
Limit the scope of the utility model.In addition, in the following description, descriptions of well-known structures and technologies are omitted, to avoid not
Necessarily obscure the concept of the utility model.
Embodiment：
As shown in Figure 1, a kind of theft-preventing mechanical lock lock core, including plug body 10, plug body 10 are provided with lockhole 11, lock
11 periphery of hole includes lock shell 12, and the lockhole 11 is internally provided with billiard mechanism, and billiard mechanism includes being arranged in lockhole 11
Hoodle 13 in portion's cavity wall, lockhole 11 are warp architecture, and warp architecture includes straight portion's chamber 111 and bending section chamber 112, and hoodle 13 is set
It sets in the cavity wall of straight portion's chamber 111.The utility model is only improved in the structure of lockhole 11, remaining actuating mechanism is all
It can be coordinated with lockhole, which is not described herein again.
The outer end of plug body 10 is provided with rotation protection handle 20, and rotation protection handle 20 is provided with corresponding with lockhole 11
Keyhole 21, rotation protection handle 20 is set to the outer end of plug body 10 by connects bayonet socket, which can hold
By fixed power, when spinning force has been more than that then bayonet is disconnected for the pressure of rotation protection handle bayonet, handle idle-run lock pin
It is motionless.
The connects bayonet socket include be arranged plug body 10 spring 31 and be set to rotation protection handle 20 and lock core sheet
Hoodle 32 between body 10, can be rotated by key.
As shown in Fig. 2, the key with lock core cooperation, including key body 50, key body 50 include being arranged in outer end
The flexible portion 51 and rigid portion arranged at the bottom 52 in portion, flexible portion 51 is made of bendable material, such as engineering plastics, nylon
Material, composite material etc. can be bent and have certain intensity, and rigid portion 52 is made of rigid material, for example, the gold such as copper
Belong to, rigid portion 52 extends to the bending section chamber 112 of lockhole.
Key is filled in into lockhole, key front end is that bendable material enters lock core bend hole and matches pin tumbler of lock cylinder, after key
End in contact rotation is protected handle and is rotated, and lock is opened.When with non-matching key brute-force rotation rotation protection handle, rotation
Strength be more than rotation protection handle bayonet pressure then bayonet is disconnected, handle idle-run lock pin is motionless.
The design of bend lock cylinder keyhole can effectively stop the illegal entrance of rigidity unlocking tool, if using flexible material
It is illegal to enter the variation that just accurately control tool；If with brute-force rotary locking cylinder, rotation protection handle automatically disengages lock core
Idle running efficiently solves the method that brute-force rotation is unlocked.
As shown in Figure 3,4, the utility model discloses a kind of theft-preventing mechanical lock, including lock body 60 again, which includes
The theft-preventing mechanical lock lock core of the utility model, lock body 60 are installed on doorframe 70, and doorframe 70 is installed in wall 80, lock core outer incline
Bend limiting holes 90 are provided with, bend limiting holes 90 include arm extending portion 91 and bend portion 92, and bend portion 92 covers lock core, hand
The diameter of arm extending portion 91 is slightly larger than the diameter of arm.When use can only one hand touch lockhole, and after hand is inside turned
Key could be filled in keyhole.
One hand turning hole limits the use of another hand of illegal unlock, and turning increases visual difficulty and operation again
Firmly difficulty avoids illegal unlock；Because having enough spaces outside doorframe, cylinder design can allow the body of lock on doorframe
Product variation more has development space, and strength failure on the door is minimum.
It should be understood that the above-mentioned specific implementation mode of the utility model is used only for exemplary illustration or explains this reality
With novel principle, without constituting limitations of the present invention.Therefore, in the spirit and scope without departing from the utility model
In the case of any modification, equivalent substitution, improvement and etc. done, should be included within the scope of protection of this utility model.In addition,
The appended claims for the utility model are intended to cover to fall into attached claim scope and boundary or this range and boundary
Whole change and modification examples in equivalent form.
