Description

Anti-opal opens lockset

Technical field

This utility model relates to lock technology field, especially relates to a kind of anti-opal and opens lockset.

Background technology

Handle, especially " 7 " font handle, be a kind of configuration relatively conventional on current lockset.The rotating handle of common handle can rotate, and it is fixed with power rail on this handle, the cross section of this power rail is the most square, and the other end of this power rail is inserted in certain revolving part of lockset, after handle drives this power rail to rotate, this revolving part rotates with, and drives the slide plate in lockset to slide, the final dead bolt action driving lockset, it is achieved open the door or lock a door.

But, handle, while facilitating user, also gives lawless person's opportunity.That is, iron wire can be stretched in door by the opal on door by lawless person, entangles handle by rule of thumb, can pull handle, it is achieved opens the door.

Utility model content

The deficiency existed for above-mentioned prior art, the purpose of this utility model is to provide a kind of anti-opal and opens lockset, and it has the advantages that to prevent lawless person to pass through opal pull handle.

To achieve these goals, this utility model be the technical scheme is that anti-opal opens lockset, including housing, a rotating handle it is articulated with on this housing, the rear end of this rotating handle is fixed with one handle after extending out to the outside of this housing, and the leading section of this rotating handle is fixed with a power rail, the bearing of trend of this power rail is same as the bearing of trend of this rotating handle

On described power rail matched in clearance be arranged with one relative to the non-rotatable brake disc of this power rail, the rear side surface of this brake disc is provided with block, and this brake disc is furnished with the spring making it have the trend of being moved rearwards by；

It is provided with forwardly convex projection, this projection and this block in described housing to match；

Be equipped with a pressing lever in described rotating handle, outside the rear end of this pressing lever is protruding to the rearward end of this rotating handle, the front end of this pressing lever abut the trailing flank of this brake disc.

Described spring is the stage clip that rear end withstands on the leading flank of this brake disc.

The cross section of described power rail is polygon, and this brake disc is provided with lumenal cross-section equally in polygonal mating holes, and aforementioned two polygons are similar.

Use after said structure, this utility model the most advantageously: lawless person can be prevented to pass through opal pull handle.Under initial condition, spring makes brake disc rearward move, thus projection keeps off in the side of block, even if there being lawless person to be suspended to handle by the iron wire put in from opal, rotating handle also cannot be made to rotate, the fabulous situation preventing improper enabling；When user needs to open the door, it is only necessary to pressing the rear end of pressing lever, can push forward brake disc, make projection cannot stop block again, brake disc can rotate freely, user rotary handle gently, power rail can be driven normally to rotate, finally open lockset.

Detailed description of the invention

Embodiment, as shown in Fig. 1 to Fig. 6: anti-opal opens lockset, including housing 10.A rotating handle 20 it is articulated with on this housing 10.The rear end of this rotating handle 20 is fixed with one handle 21 after extending out to the outside of this housing 10.This handle 21 and this rotating handle 20 can be structure as a whole, and the two can be in " 7 " font.The leading section of this rotating handle 20 is fixed with a power rail 30, and the bearing of trend of this power rail 30 is same as the bearing of trend of this rotating handle 20.The front end of this power rail 30 is generally received in certain revolving part of corresponding lockset, and this revolving part can drive the slide plate in lockset to slide after rotating, the final dead bolt action driving lockset.

Concretely:

On this power rail 30, matched in clearance is arranged with one relative to this non-rotatable brake disc of power rail 30 40.That is, this brake disc 40 can slide anteroposterior, but non-rotatable relative to this power rail 30.In the present embodiment, the cross section of this power rail 30 is polygon, and this brake disc 40 is provided with lumenal cross-section equally in polygonal mating holes, and aforementioned two polygons are similar.Such as, the cross section of this power rail 30 and the lumenal cross-section of this mating holes are the most square, and these two foursquare sizes are more or less the same.Meanwhile, the rear side surface of this brake disc 40 is provided with the block 41 protruded backward, and this brake disc 40 is furnished with the spring 42 making it have the trend of being moved rearwards by.

Being provided with forwardly convex projection 11 in this housing 10, this projection 11 and this block 41 match.That is, this projection 11 can keep off in the side of this block 41, makes this brake disc 40 to rotate, and finally this power rail 30 is non-rotatable.

A pressing lever 50 it is equipped with in this rotating handle 20.Outside the rear end of this pressing lever 50 is protruding to the rearward end of this rotating handle 20, the front end of this pressing lever 50 abut the trailing flank of this brake disc 40.Certainly, the rear end of this pressing lever 50 is preferably provided with a block.

So, shown in Fig. 3 and Fig. 4, initial condition to, this spring 42 makes this brake disc 40 rearward move, and this projection 11 keeps off in the side of this block 41, even if having lawless person to put in iron wire by opal be suspended to this handle 21, this rotating handle 20 also cannot be made to rotate；Shown in Fig. 5 and Fig. 6, when user needs to open the door, only need to press the rear end of this pressing lever 50, can outwards push this brake disc 40, make this projection 11 cannot stop this block 41 again, this brake disc 40 can rotate freely, and user rotates this handle 21 gently, and this power rail 30 can be driven normally to rotate.

Optimize:

This spring 42 withstands on the stage clip on the leading flank of this brake disc 40 for rear end.In the present embodiment, the rear end of this spring 42 is directly anchored on the leading flank of this brake disc 40.Obviously, the other end of this spring 42 withstands on this housing 10 or withstands on door-plate.Such mode is relatively simple.

The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description and accompanying drawing content to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical fields, the most in like manner it is included in scope of patent protection of the present utility model.
