Abstract

The utility model discloses a handle for a loosening-free structure of a door lock, which comprises a handle body and a lock catch cap, wherein a handle reset mechanism is arranged in the lock catch cap; and the linkage fit between the handle body and a spring shifting piece is formed by axial grooves which are symmetrically arranged on the connecting end surface of the handle body and convex lugs which are arranged in inner holes of the spring shifting piece and can be clamped in the axial grooves. The handle is characterized in that an annular locking groove is arranged at the connecting end of the handle body; buckling legs which can be screwed into the annular locking groove at the connecting end of the handle body are symmetrically arranged on a penetrating hole at the handle connecting end of a bottom cap of the lock catch cap; and the width of each buckling leg is equal to that of each convex lug in the inner holes of the spring shifting piece. By using clamped fit between the annular locking groove at the connecting end of the handle body and the buckling legs on the lock catch cap, the defects that the adopted fastening bolt is easy to loosen and the handle body is displaced and loosened or falls in the prior art are overcome; and no tool is required for assembly between the handle body and a lock body square shaft so as to bring convenience in mounting of the handle.

Description

A kind of door lock does not have the release construction handle

Technical field

The utility model relates to the door lock parts, especially a kind of door lock does not have the release construction handle.

Background technology

At present, be applicable on the market that gatekeeper's hand holding lock is all kinds of a lot, hand holding lock is made of lock body that is provided with dead bolt and inside and outside handle usually.Lock body is installed on the body, and inside and outside handle and the link of lock body are provided with the lock bodies square shaft and insert the square opening that cooperates, after inside and outside handle passes through the link square opening respectively and lock body two side core shaft ends insertings is connected, passes through screw again.For impelling handle to reset immediately after manipulation, handle disposes the snap lid that is built-in with the handle resetting-mechanism usually.This snap lid is connected as one by screw by interior cover and the bottom that is provided with the spring buckle ear, and snap lid is provided with for its installing hole fixing on the door body.The handle resetting-mechanism is by constituting with cover inner spring buckle ear two card base springs that interlock and the spring plectrum that can stir two card base springs.Being linked between handle body and the spring plectrum is opened in the handle body by symmetry and is connected the axial groove of end face and is arranged on the lug that spring plectrum endoporus can snap in the axial groove and constitute.There is following defective in the connected mode of this handle and door lock side's mandrel:

One, the screw that is used for fastening handle exposes usually, can influence door lock and on the door body whole structure is installed;

Two, along with handle frequently to the manipulation of pushing of door lock, trip bolt can become flexible, handle is with that diastema also can take place cooperating of door lock side's mandrel is loosening, the loosening comfortable feel degree that can influence in the handle manipulation of this diastema;

Three, when trip bolt is loosening when breaking away from the contacting of square shaft fully, handle can be deviate from from square shaft.

Summary of the invention

Technical problem to be solved in the utility model is to remedy above-mentioned the deficiencies in the prior art, provides a kind of loosening door lock of handle and square shaft diastema of eliminating not have the release construction handle.

The utility model is solved by the following method.

This door lock does not have the release construction handle, comprising: the handle body and in be provided with the snap lid of handle resetting-mechanism; Described snap lid is connected as one by screw by interior cover and the bottom that is provided with the spring buckle ear, and snap lid is provided with for its installing hole fixing on the door body; Described handle resetting-mechanism is by constituting with cover inner spring buckle ear two card base springs that interlock and the spring plectrum that can stir two card base springs; Being linked between described handle body and the spring plectrum is opened in the handle body by symmetry and is connected the axial groove of end face and is arranged on the lug that spring plectrum endoporus can snap in the axial groove and constitute; Described handle body connects end face and is provided with the square opening that the lock bodies square shaft is inserted cooperation.

The characteristics that this door lock does not have the release construction handle are:

The link of described handle body is provided with annular lock groove;

The handle link of the bottom of described snap lid places and is arranged with the button pin that can screw in handle body link annular lock groove on the hole, and the lug on button pin and the spring plectrum endoporus is wide.

When the connection end face axial groove of handle body is aimed at the bottom symmetry button pin of snap lid, the handle body just can insert snap lid smoothly, then handle is rotated to the left or to the right 90 degree, the annular lock groove of handle body link can screw in bottom symmetry button pin, constitutes one with snap lid.

The utility model beneficial effect compared with prior art is:

This door lock does not have the release construction handle, utilization is arranged on handle body link annular lock groove and cooperates with snapping in of pin of button on the snap lid, replace and to be screwed being connected of handle and square shaft in the prior art, the snap-in cooperation of this machinery has not only overcome prior art and has adopted trip bolt loosening easily, handle is known from experience the defective that diastema is loosening or come off, and going up assembling between handle body and lock body square shaft no longer needs instrument, has made things convenient for the installation of handle.

The concrete structure that the utility model door lock does not have the release construction handle is provided in detail by the following drawings and embodiment.

Description of drawings

Fig. 1 is the structural representation that door lock does not have the release construction handle;

Fig. 2 is the decomposition texture schematic diagram that door lock shown in Figure 1 does not have the release construction handle.

The specific embodiment

Embodiment: can be clear that from Fig. 1 and Fig. 2 door lock does not have the release construction handle, comprising: handle body 1 and in be provided with the snap lid 2 of handle resetting-mechanism 3.

Described handle body 1 is provided with the square opening 12 that the lock bodies square shaft is inserted cooperation with the end face 11 that is connected of lock body.Link 13 axial planes of described handle body 1 are provided with annular lock groove 14;

Described snap lid 2 is connected as one by screw 23 by interior cover 21 and the bottom 22 that is provided with spring buckle ear 211, and snap lid 2 is provided with for its installing hole 24 fixing on the door body.The handle link of the bottom 22 of snap lid 2 places and is arranged with the button pin 222 that can screw in handle body 1 link 13 annular lock grooves 14 on the hole 221.

Described handle resetting-mechanism 3 is by constituting with cover 21 inner spring buckle ears 211 two card base springs 31 that interlock and the spring plectrum 32 that can stir two card base springs 31.

Being linked between described handle body 1 and the spring plectrum 32 is opened in handle body 1 by symmetry and is connected the axial groove 15 of end face 11 and is arranged on the lug 322 that spring plectrum 32 endoporus 321 can snap in axial groove 15 and constitute.
