Abstract

The utility model discloses a door and window shifting fork handling structure, which comprises a casing, a handle and a shifting fork. The handle is in running fit with the casing, a gear and a rack which coordinate with each other are disposed in the casing, the gear is connected onto the handle in a sleeved manner, and the shifting fork is arranged on the rack. After adopting the technical scheme and by the aid of coordinative transmission of the gear and the rack which are more compact in structure, flexibility of locking and unlocking actions of a lock driven by means of rotating the handle is greatly improved, coordinative abrasion of the gear and the rack is less, repair rate is decreased, and noise produced by handling is extremely low due to compact coordination when the handle rotates.

Description

A kind of door and window shift fork handle structure

Technical field:

The utility model relates to a kind of door and window shift fork handle structure.

Background technology:

The aluminium door and window of prior art all is provided with the shift fork that belongs to lock members with handle inside, traditional structure is that drive link is installed on shift fork, drive link is provided with chute, the end that handle housing inner handle connects the handle housing is provided with pin, pin passes chute, the action that utilizes handle to rotate, by cooperating of pin and chute, drive link is moved with shift fork, the action that realization is locked and unblanked, this handle structure structure is comparatively loose, the diastema of pin and chute is bigger, cause the handle rotation amplitude more just can lock, and pin is worn easily, the noise of locking and unblank is bigger.

Summary of the invention:

The purpose of this utility model is in order to overcome the shortcoming of above-mentioned prior art, and a kind of compact conformation, durable, door and window shift fork handle structure that noise is low are provided.

For achieving the above object, the technical scheme that the utility model provides is: a kind of door and window shift fork handle structure includes housing, handle and shift fork, handle becomes to be rotatably assorted with housing, be provided with the gear and the tooth bar of working in coordination in housing, geared sleeve is connected on the handle, and shift fork is located on the tooth bar.

After adopting technique scheme, utilize the comparatively cooperation transmission of compact gear and tooth bar of structure, handle rotates locking of drive lockset and the sensitivity of unlocking action is greatly improved, and the cooperation of wheel and rack wearing and tearing are less, reduced maintenance rate, owing to cooperate compactness, when handle rotated, the noise that handle sends was very little.

Description of drawings:

Fig. 1 is the structure chart of the utility model door and window shift fork handle;

Fig. 2 is the three-dimensional exploded view of the utility model door and window shift fork handle;

Fig. 3 is the structural representation after the utility model door and window shift fork handle turns an angle.

The specific embodiment:

Now elaborate the utility model in conjunction with the accompanying drawings:
