Abstract
The invention discloses an anti-theft device of a lock handle, comprising: the door inner handle is used for being driven by a hand and is rotatably arranged on the door body; the unlocking mechanism can be driven by the inner door handle and is used for unlocking the lock body; and two ends of the clutch mechanism are in transmission connection with the door inner handle and the unlocking mechanism respectively, and the clutch mechanism can be controlled in the door. When the door lock is unlocked by adopting the structure, the clutch mechanism is required to be operated to connect the unlocking mechanism and the inner door handle, then the handle is rotated to unlock the door, so that the door lock can be prevented from being unlocked by hooking the handle through the cat eye after the cat eye is damaged by lawless persons, the lawless persons can unlock the door by operating the clutch mechanism to connect the unlocking mechanism and the inner door handle, but the clutch mechanism is extremely difficult to operate from the outside, the unlocking difficulty through the cat eye can be greatly increased, and the anti-theft performance of the door lock is further improved.
Description
Technical field
The present invention relates to door lock field, particularly relate to a kind of anti-theft device of lock handle.
Background technology
Existing door body is generally provided with opal, offender is sometimes by destroying opal, then unblanked from pull handle in door by instrument, this process operation is comparatively simple, is easy to realize, is unfavorable for antitheft, the present invention is directed to the anti-theft device that this scheme designs a kind of lock handle especially, the unlocking difficulty of this scheme can be increased substantially, and then be significantly decreased through the situation that opal carries out unblanking and occur, improve the theftproof performance of door lock.
Summary of the invention
In order to solve the problem, the invention provides a kind of anti-theft device of lock handle.
The technical solution adopted for the present invention to solve the technical problems is:
An anti-theft device for lock handle, comprising:
Door Internal handle, for for hand-drive, is installed in rotation on a body;
Unlocking mechanism, drives, for opening lock body by door Internal handle;
Clutch, two ends are in transmission connection with door Internal handle and unlocking mechanism respectively, and clutch can manipulate in door.
The socket that described clutch comprises button axle, plug, back-moving spring and coordinates with plug, described door Internal handle is provided with through hole, described plug is connected with button axle, and the two is slidably mounted in this through hole, described back-moving spring is positioned at through hole, one end is connected with through hole, and the other end is connected with button axle; Described socket is arranged on unlocking mechanism.
Described plug comprises a pointed nose and a columnar part, and pointed nose is positioned at front end, and columnar part is connected with pointed nose rear end.
Described socket is provided with the shrinkage pool matched with plug, this shrinkage pool includes V-type slotted eye and cylindricality slotted eye.
The invention has the beneficial effects as follows: clutch must be operated when adopting the present invention of said structure to unblank and unlocking mechanism is connected with door Internal handle, then swing handle can be unblanked, move handle by opal hook after can preventing lawless person from destroying opal to unblank, lawless person needs at operation clutch, unlocking mechanism to be connected can be unblanked with door Internal handle, but from outside pole difficulty operation clutch, the difficulty of being unblanked by opal can be increased considerably, and then improve the theftproof performance of door lock.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is decomposing schematic representation one of the present invention;
Fig. 2 is decomposing schematic representation two of the present invention;
Fig. 3 is the schematic diagram of socket of the present invention.
Detailed description of the invention
With reference to Fig. 1-Fig. 3, the present invention is a kind of anti-theft device of lock handle, comprising:
Door Internal handle 1, for for hand-drive, is installed in rotation on a body;
Unlocking mechanism 2, drives by door Internal handle 1, for opening lock body 0;
Clutch, two ends are in transmission connection with door Internal handle 1 and unlocking mechanism 2 respectively, and clutch can manipulate in door.Clutch must be operated when adopting the present invention of said structure to unblank unlocking mechanism 2 is connected with door Internal handle 1, then swing handle can be unblanked, move handle by opal hook after can preventing lawless person from destroying opal to unblank, lawless person needs swing handle after unlocking mechanism 2 is connected with door Internal handle 1 by operation clutch to unblank, but operate clutch from extremely difficult outdoors, the difficulty of being unblanked by opal can be increased considerably, and then improve the theftproof performance of door lock.
As shown in the figure, clutch specifically can adopt following embodiment, the socket 33 comprising button axle 31, plug, back-moving spring 32 and coordinate with plug, door Internal handle 1 is provided with through hole 34, plug is connected with button axle 31, and the two is slidably mounted in this through hole 34, and back-moving spring 32 is positioned at through hole 34, one end is connected with through hole 34, and the other end is connected with button axle 31; Socket 33 is arranged on unlocking mechanism 2.Adopt the concrete course of action of clutch of said structure as follows, pressing keys axle 31 drives plug to move inward, formed to plug insertion socket 33 and connect, then swing handle can open the door, after removing the external force be applied on button axle 31, under the effect of back-moving spring 32, button axle 31 is mobile outward resets.
As shown in the figure, plug comprises pointed nose 35 and a columnar part 36, and pointed nose 35 is positioned at front end, and columnar part 36 is connected with pointed nose 35 rear end; Corresponding socket 33 is provided with the shrinkage pool matched with plug, and this shrinkage pool includes V-type slotted eye 37 and cylindricality slotted eye 38.Docking of plug and socket 33 can be made the coordinating of pointed nose 35 and V-type slotted eye 37 to have certain tolerance (plug and socket 33 can realize automatic aligning in certain angle, namely plug and socket 33 do not align completely and also can achieve a butt joint), columnar part 36 coordinates with cylindricality slotted eye 38 can reduce the power that the plug and socket after automatic aligning 33 feeds back to button axle 31 in transmission process, reduce the dynamics requirement to pressing keys axle 31, make to unblank more to stablize.
Above-described embodiment is preferred version of the present invention, and the present invention also can have other embodiments.Those skilled in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and these equivalent modification or replacement are all included in the scope set by the application's claim.
