Description
Technical field
The utility model relates to safe-guard door lock field.
Background technology
Present safe-guard door lock, generally by lock body, outer handle, interior handle, lock core four part forms.Outer handle and interior handle are all provided with the handle for opening the door, and in general, handle all can directly open the door, and provide conveniently so just to illegal invasion person.Illegal invasion person with instrument by opal, directly can press down interior handle and opens the door, there is serious potential safety hazard.Also there is now the interior handle of electronic lock, take arrangement of clutch, but its arrangement of clutch complex structure, to such an extent as to be difficult to extensive use.
Summary of the invention
The purpose of this utility model is to provide a kind of security door handle clutch device, and structure is simple, improves house security coefficient.
The technical solution of the utility model is: a kind of security door handle clutch device, it is characterized in that handle and backplate are arranged on panel, handle torsion spring, banking stop and circlip are arranged on handle, button, button spring and clutch post order is arranged in the cavity of handle, button spring is arranged between button and clutch post, clutch post torsion spring is arranged between clutch post and backplate, and square steel is arranged in the cavity of clutch post.
A described button part is multiple edge body, and a part is cylinder, and there is polygonal-shaped cavities cylinder inside, and described multiple edge body is non-circular equilateral how stupefied body or spline, and the polygonal-shaped cavities of described button is equilateral polygon or spline.
A described clutch post part is multiple edge body, and a part is cylinder, and there is quadrangle cavity cylinder inside, and described multiple edge body is non-circular equilateral how stupefied body or spline.
The multiple edge body part of described clutch post is identical with the polygonal-shaped cavities some types of button cylinder inside and be matched in clearance.
A cavity part for described handle is polygon, and a part is circular, and four polygonal-shaped cavities parts of handle are identical with the multiple edge body some types of button and be matched in clearance, the circular cavity part of handle and the barrel portion matched in clearance of clutch post.
The utility model directly ought press down interior handle and can not open the door, and effectively prevents employing instrument to press down the problem of interior handle enabling by opal, improves house security.

Wherein drawing reference numeral is as follows: panel 1, handle 2, button 3, button spring 4, handle torsion spring 5, banking stop 6, circlip 7, clutch post 8, clutch post torsion spring 9, backplate 10, square steel 11
Detailed description of the invention
As shown in Figure 1, Figure 2, Figure 3 and Figure 4: handle 2 and backplate 10 are arranged on panel 1, handle torsion spring 5, banking stop 6 and circlip 7 are arranged on handle, button 3, button spring 4 and clutch post 8 order is arranged in the cavity of handle 2, button spring 4 is arranged between button 3 and clutch post 8, clutch post torsion spring 9 is arranged between clutch post 8 and backplate 10, and square steel 11 is arranged in the cavity of clutch post 8.
Under normal initial situation, button 3 is under the spring-force driven dual of button spring 4, separated position is in clutch post 8, directly press down interior handle can not open the door, button 3 need be pressed with finger during enabling, button 3 is made to overcome the spring force motion of button spring 4, along with the motion of button 3, the part of button 3 hollow is combined with the part of clutch post 8 evagination, when handle 2 rotates, the revolving force of handle 2, clutch post 8 is passed to by button 3, clutch post 8 passes to square steel 11 again, just complete the transmission of moment of torsion, lock body is driven to rotate and unblank, if do not press button 3, it is released states that button 3 moves with clutch post 8, directly press down interior handle, clutch post 8 non rotating, square steel 11 also can not rotate, also just lock body is not driven to rotate, therefore lock can not be opened.By this method, effectively prevent employing instrument to press down the problem of interior handle enabling by opal, improve house security.
