Abstract
The invention discloses a kind of efficiently protection theftproof locks; including the lock panel being mutually fastened and connected and bottom-locking plate; handle is installed in the lock panel; the inner end of the handle is connect by clutch with one end of square steel connector; the other end of the square steel connector with for driving the square steel of lock core to connect; the square steel is located at the bottom-locking plate side and central shaft is vertical with the bottom-locking plate; it is located at the position around the square steel on the bottom-locking plate and is equipped with evagination and the first bulge loop around the square steel periphery, the height of first bulge loop is 1 10mm.The present invention in the periphery of unlocking key, that is, square steel by being arranged bulge loop, it can effectively stop that thin slice tool is inserted by the gap between lock and door and controls square steel rotation by criminal, the security risk for implementing crime to prevent criminal by the gap illegal unlock between lock and door, improves the anti-theft performance of lock.
Description
Technical field
The present invention relates to a kind of door lock more particularly to a kind of it can prevent criminal from being controlled by gap between lock and door
The efficient protection theftproof lock that square steel processed is unlocked.
Background technology
The anti-theft performance of door lock is the important evidence of its quality, and many door locks pass through key or micromotor control at present
Unlocking part rotation processed is realized by unlocking part band movable lock core rotation and is unlocked, if criminal passes through the gap between lock and door
It realizes the control of split latch fitting, then can bypass key or micromotor is realized and unlocked, reduce the anti-theft performance of volume lock.
For example, electronic lock is widely used because its is easy to use, anti-theft performance is good, present various business places such as guest
All electronic lock is being widely used in shop, hotel etc., and many families also begin to use electronic lock.The handle of electronic lock by clutch with
Square steel connector connects, and clutch is controlled by micromotor, and square steel connector is connect with square steel, and square steel is exactly above-mentioned unlocking
Part directly drives the function that switch lock is realized in lock core rotation.If criminal by very thin steel disc be inserted into lock and door it
Between gap and block square steel, then can bypass clutch realize unlock, cause many hidden danger to the safety of user.
Invention content
The purpose of the present invention be that solve the above-mentioned problems and provide one kind can prevent criminal by lock with
Realize the efficient protection theftproof lock unlocked in gap between door.
The present invention is achieved through the following technical solutions above-mentioned purpose：
One kind efficiently protecting theftproof lock, including the lock panel and bottom-locking plate being mutually fastened and connected, and handle is equipped in the lock panel
The inner end of hand, the handle is connect by clutch with one end of square steel connector, the other end and use of the square steel connector
In the square steel connection of driving lock core, the square steel is located at the bottom-locking plate side and central shaft is vertical with the bottom-locking plate, institute
It states the position on bottom-locking plate being located at around the square steel to be equipped with evagination and surround the first bulge loop of the square steel periphery, described first
The height of bulge loop is 1-10mm.
According to the actual application, first bulge loop is round or rectangular bulge loop, and ring wall is solid or its ring
Wall is equipped with opening or through-hole.
According to using needs, first bulge loop is becket, is integrally formed or is welded to connect with the bottom-locking plate.
Criminal damages installation screw rod and unlocks in order to prevent, and the position on the bottom-locking plate by two close end is respectively equipped with peace
Screw hole is filled, the position around the installation screw is located on the bottom-locking plate and is equipped with evagination and around the installation screw periphery
The height of second bulge loop, second bulge loop is 1-10mm.
The beneficial effects of the present invention are：
The present invention can effectively stop criminal by thin slice tool by the way that the first bulge loop is arranged in the periphery of unlocking key, that is, square steel
Square steel rotation is inserted into and controlled by the gap between lock and door, passes through the gap between lock and door to prevent criminal
The security risk of crime is implemented in illegal unlock, improves the anti-theft performance of lock.
Description of the drawings
Fig. 1 is the dimensional structure diagram of traditional locks；
Fig. 2 is the dimensional structure diagram of efficient protection theftproof lock of the present invention.
Specific implementation mode
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, traditional locks include the lock panel 6 being mutually fastened and connected and bottom-locking plate 2, handle 1 is installed in lock panel 6,
The inner end of handle 1 passes through clutch（Do not show in inside, figure）Connect with one end of square steel connector 4, square steel connector 4 it is another
One end is with for driving the square steel 5 of lock core to connect, and square steel 5 is located at 2 side of bottom-locking plate and central shaft is vertical with bottom-locking plate 2, side
There is no the barrier structure of protrusion around steel 5, if thin slice tool is inserted into simultaneously by criminal by the gap between lock and door
Square steel is blocked, square steel rotation can be controlled, to which bypass clutch realizes illegal unlock.In addition, passing through peace with screw rod when installation
Filling screw hole 7 can also illegal unlock if criminal breaks screw rod.
As shown in Fig. 2 and Fig. 1, efficient protection theftproof lock of the present invention includes the lock panel 6 being mutually fastened and connected and lock
Bottom plate 2 is equipped with handle 1 in lock panel 6, and the inner end of handle 1 passes through clutch（Do not show in inside, figure）With square steel connector
4 one end connection, for the other end of square steel connector 4 with for driving the square steel 5 of lock core to connect, square steel 5 is located at 2 side of bottom-locking plate
And central shaft is vertical with bottom-locking plate 2, above structure is consistent with traditional locks, and different structure of the invention is：Bottom-locking plate 2
The upper position around square steel 5 is equipped with evagination and the first bulge loop 8 around 2 periphery of square steel, and the height of the first bulge loop 8 is 1-
10mm, the first bulge loop 8 are round bulge loop, or rectangular bulge loop, ring wall are solid, can also be equipped on its ring wall
Opening or through-hole, the first bulge loop 8 are becket, are integrally formed, can also be welded to connect with bottom-locking plate 2.It is close on bottom-locking plate 2
The position at both ends is respectively equipped with installation screw 7, and the position around installation screw 7 is located on bottom-locking plate 2 and is equipped with evagination and around peace
The second bulge loop 9 of 7 periphery of screw hole is filled, the height of the second bulge loop 9 is 1-10mm.
The rubber washer 3 fitted on bottom-locking plate 2 is also shown in Fig. 1 and Fig. 2.
As described in Figure 2, after the present invention increases by the first bulge loop 8, if criminal passes through thin slice tool between lock and door
Gap be inserted into, then can be stopped by the first bulge loop 8, square steel can not be blocked, to can not bypass clutch realize illegal unlock, reach
To antitheft purpose.After increasing by the second bulge loop 9, criminal cannot cannot destroy screw rod, further enhance anti-theft performance.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as
