Abstract

The utility model relates to a direction exchange type universal handle of a lock, which is characterized in that a handle is divided into two portions, a handle body and a handle head that is equipped with a groove and is axially equipped with a notch. The central position of the handle head is also equipped with a quadrate core hole; the opening position of the handle body is equipped with a circular hole and a quadrate core hole in concave mode; the position of the circular hole is equipped with a lug. The lug on the handle body is clamped in the groove by the notch on the handle head, and the handle body and the handle head are mutually rebbetted. In the direction exchange type universal handle of the lock of the utility model, the handle is divided into the two portions, the handle body and the handle head, the direction exchange type universal handle of the lock has simple and reasonable structure and convenient and fast operation, is firm and reliable, and is suitable for exchanging directions of asymmetric and symmetrical handles.

Description

Reversing universal latch handle

Technical field

The utility model relates to a kind of Handle for lock, particularly a kind of reversing universal latch handle.

Background technology

The compound plate hand holding lock is divided into a left side usually to be driveed with the right side and opens, and L.H.flapped door must be selected the L.H.flapped door lock for use, and R.H.flapped door must be selected the R.H.flapped door lock for use, when the direction of the direction of lock and door is inconsistent, must carry out the handle commutation; Existing handle commutating structure is greatly to being divided into three major types:

One, changes type commutating structure (Fig. 1) fully

This kind structure handle is a monolithic, and part is enclosed within on the handle successively, at last jump ring is contained in the jump ring groove of end, and handle is connected with panel.All parts must be pulled down during the commutation of this structure, after handle is exchanged, reinstall again, the time-consuming face component of damaging easily again during this structure operation.

Two, screw fastening type commutating structure (Fig. 2)

Do not have draw-in groove on this structure handle, only two handles are connected with Fang Xin, back out the screw on two handles during commutation, take off and refill after handle is exchanged by two screws.This structure, more convenient during commutation, but handle is easily by artificial destruction, and (only need back out screw just can take handle away outside) greatly reduces theftproof performance and survivability.

Three, symmetrical handle type commutating structure (Fig. 3)

The handle of symmetry handle type commutating structure is a monolithic, handle is inner puts rotatable 180 degree of the relative panel of mechanism, can forward the right (or forward the left side by the right) to by the left side, and this structure operation is simple, but only be applicable to symmetrical handle, and can not be used for asymmetric handle.

Summary of the invention

It is a kind of simple and reasonable that the purpose of this utility model is to provide, and simple operation is solid and reliable, can adapt to the reversing universal latch handle of asymmetric and symmetrical handle commutation.

The purpose of this utility model can reach by following measure: a kind of reversing universal latch handle, it is characterized in that: handle is divided into handle body and handle head two parts, handle head is provided with groove, and be provided with breach in the axial direction, the side's of being provided with core hole also in the center, handle body opening part is recessed a circular hole and side's core hole deeply, and is provided with projection at the circular hole place, projection on the handle body is connected in the groove by the breach on the handle head, and handle body and handle head are rabbeted mutually.

The purpose of this utility model can also reach by following measure: the breach on the handle head is two, and the projection on the handle body also is two.The descending transition of groove on the handle head.The handle body is divided into left handle and right handle, and the projection direction on the left and right handle differs 90 degree.Fang Xin is plugged in the square core hole of the square core hole of handle body and handle head.

The utility model has following advantage compared to existing technology: handle is divided into handle body and handle head two parts, and simple and reasonable, simple operation, solid and reliable is applicable to the commutation of asymmetric and symmetrical handle.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 4～Figure 15, the utility model is divided into handle body 1 and handle head 2 two parts.Handle body 1 is divided into left handle and right handle; The opening part of handle body 1 is recessed a circular hole 1-2 and square core hole 1-3 deeply, and is provided with two projection 1-1 at circular hole 1-2 place; Projection 1-1 direction on left side handle and the right handle differs 90 degree.Handle head 2 is identical with traditional handle structure with the end that panel connects, and the other end is established a groove 2-1 on the end face certain distance, the descending transition of groove 2-1; And be provided with two breach 2-2 in the axial direction; Also be provided with side's core hole 2-3 in the center.Projection 1-1 on the handle body 1 can be embedded in groove 2-1 by the breach 2-2 on the handle head 2 and rotate.

During installation, with jump ring handle head 2 is fixed on the panel earlier, two projection 1-1 on the handle body 1 aim on the handle head 2 and insert behind the two breach 2-2, rotate handle body 1 again, projection 1-1 can snap in groove 2-1, treat both square core hole (1-3) and (2-3) alignment after can the side's of insertion core 3.During commutation, in panel, dial below core 3, handle body 1 is upwards turned an angle, projection 1-1 is separated with groove 2-1, and take off handle body 1 along breach 2-2; After two handle bodies 1 are exchanged, the breach 2-2 that handle body 1 projection 1-1 is aimed at handle head 2 inserts again, and rotate an angle, at this moment the projection 1-1 on the handle body 1 enters the groove 2-1 of handle head 2, the square core hole 1-3 and the 2-3 that treat both align to insertion side's core 3, handle body 1, handle head 2, square core 3 are firmly become one, finish commutation.
