Abstract
The utility model discloses a super-force protection device for a lock, comprising a return spring and a handle connecting seat, which the return spring is arranged between a handle and the handle connecting seat, and, a pressure cover with one side a groove arranged, an elastic device and a fixation seat with a slot arranged in the center. The handle connecting seat is meshed with the groove arranged on one side of the pressure cover by convex teeth arranged on one side of the handle connecting seat, while the other side of the pressure cover orderly and respectively contacts the elastic device and the fixation seat. The fixation seat is installed on a main body seat by through holes arranged on the main body seat. The utility model has advantages as below: when the handle is turned to a limit position or under the situation of incapability of opening the lock, if still turning the handle by force, the elastic device can be compressed by the handle connecting seat by the pressure cover so that a plucking mechanism of the handle cannot be damaged and the whole lock can be protected when the handle is in a turning state.
Description
Technical field
The utility model relates to the lock field, more particularly relates to a kind of super protection unit of trying hard to keep that has the lock of handle.
Background technology
At present, known lock generally comprises lock body, handle and the handle connecting seat that directly is connected with handle, the back-moving spring that common handle resets is installed between handle and the handle connecting seat, when swing handle is opened lock, handle drives pulling mechanism and turns to extreme position, and handle resets under the effect of back-moving spring then.But after handle turns to extreme position or under the situation that can't open lock,, be easy to the pulling mechanism of handle is destroyed, thereby whole lock can't be used if still exert oneself swing handle.The application number of a Chinese patent is 91105441, the applying date is on August 9th, 1991, denomination of invention is a mechanical combination door-lock with high performance, this invention relates to a kind of high-performance mechanical formula cipher door lock, it comprises lock body and tapered end two parts, lock body comprises that at least dead bolt, the tapered end with mandrel interlock comprises the outer unlatching handle of mandrel and interlock with it and the part that the control mandrel rotates, and this control section comprises a plurality of buttons, the card key corresponding with button, has the interlock plate of the slot of peripheral notches with the band that blocks the setting of key quadrature.The pedestal of a plurality of slits, the spring of reset interlock plate and a plurality of installation card keys are arranged, and the card key comprises major key, inferior key and reset key, when assembling, and the inboard symmetry of major key and time key, there is asymmetric square recess in the outside.This lock also is easy to occur situation recited above, makes whole lock all can't use at last.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and provide a kind of simple in structure, can prevent the super protection unit of trying hard to keep of a kind of lock that the handle locked is not destroyed under by the situation of Overexertion effectively.
The utility model is to adopt following technical scheme to realize above-mentioned purpose:
The super protection unit of trying hard to keep of lock; comprise back-moving spring and handle connecting seat; back-moving spring is installed between handle and the handle connecting seat; it comprises that also a side is provided with the holder that the gland of groove, elastic device and center are provided with slot; the set groove of a side is meshed on the double wedge of handle connecting seat by the setting of one side and the gland; the opposite side of gland contacts with elastic device and holder respectively successively, and holder is installed on the main body pedestal by through hole set on the main body pedestal.
The utility model can also be done following improvement to technique scheme:
A described side at holder can be provided with groove, and elastic device and gland can be installed in the groove of holder.
Described elastic device can be the compression rubber cushion.
Described elastic device also can be spring.
Adopted the following advantage of the utlity model has of said structure:
1, after handle turns to extreme position or under the situation that can't open lock; if still exert oneself swing handle; handle connecting seat can pass through gland elasticity of compression device; handle is under situation about can rotate like this; the pulling mechanism of handle can not destroyed, thereby whole lock has also been played the effect of protecting.
2, can't open when being locked in, and the people be arranged still firmly during swing handle, handle can or not reset under the situation of elasticity of compression device, can give a kind of illusion of people, thinks that lock is destroyed, makes the people can not be rotated further handle.
3, in order to dwindle the volume of whole lock, simultaneously also in order to reach the attractive in appearance of profile, be provided with groove in a side of described holder, elastic device and gland can be installed in the groove of holder.
4, the double wedge that is provided with on the compression rubber cushion can improve the elastic performance of compression rubber cushion.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a partial sectional view of the present utility model;
Fig. 2 is the structural representation of the utility model handle connecting seat;
Fig. 3 is the structural representation of the utility model gland;
Fig. 4 is the structural representation of the utility model holder;
Fig. 5 is the lateral view of Fig. 4.
The specific embodiment
As Fig. 1; Fig. 2; Fig. 3; Fig. 4 and shown in Figure 5; the super protection unit of trying hard to keep of lock; comprise back-moving spring 1 and handle connecting seat 2; handle connecting seat 2 is fixed together with handle 3; back-moving spring 1 is installed between handle 3 and the handle connecting seat 2; it comprises that also a side is provided with the gland 4 of groove 41; elastic device 5 and center are provided with the holder 6 of slot 61; the set groove 41 of a side is meshed on the double wedge 21 of handle connecting seat 2 by the setting of one side and the gland 4; the opposite side of gland 4 contacts with elastic device 5 and holder 6 respectively successively; holder 6 is installed on the main body pedestal 7 by through hole set on the main body pedestal 7 71, and contacts with the pushing piece of being controlled by code keypad 8.
The utility model can also be done following improvement:
In order to dwindle the volume of whole lock, simultaneously also in order to reach the attractive in appearance of profile, side at described holder 6 can be provided with groove 62, elastic device 5 and gland 4 can be installed in the groove 62 of holder 6, described elastic device 5 can be the compression rubber cushion, can be provided with double wedge on described compression rubber cushion, so that the compression rubber cushion has the better elastic performance, the also available spring of described elastic device 5 replaces.
Operating principle: when the enough correct passwords of people's energy are opened lock, the pushing piece of being controlled by code keypad 8 will be opened, and swing handle 3 gets final product the unlatching of control lock; When the people can not open lock with correct password; pushing piece 8 by code keypad control will be lockable; 3 of handles can not rotate, if the people is arranged still firmly during swing handle 3, handle connecting seat 2 will be by gland 4 promotion elastic devices 5; it is promptly rotatable that elastic device 5 is compressed back handle 3; but do not have resetting means that handle 3 is resetted this moment, can give a kind of illusion of people, thinks and lock destroyed and swing handle no longer; thereby played protective effect, had only artificial handle 3 could being resetted lock.
