Abstract

The utility model discloses a lever handle mechanism of a mechanical door lock. The lever handle mechanism of the mechanical door lock comprises a lever handle and a lever handle rotating shaft, wherein a lever handle positioning washer is arranged at the other end of the lever handle rotating shaft, a limiting convex block is arranged under the lever handle positioning washer, door lock limiting block groups are arranged on two sides of the lever handle positioning washer, and a liming groove used for limiting moving range of the limiting convex block is arranged on each door lock limiting block group. According to the lever handle mechanism of the mechanical door lock, through reasonable structural modification, especially the design of the door lock limiting block groups, limitation to the pressing angles or anti-lifting swing angles of the lever handle is achieved, the structure is light and simple, installation and maintenance are quite convenient, and the lever handle mechanism is suitable for various common lever-handle type door locks, especially lever-handle anti-lifting door locks. In addition, through the arrangement of washer locking pieces, anti-theft strength is effectively enhanced, and the lever handle mechanism of the mechanical door lock has good practical value.

Description

A kind of mechanical door lock handle mechanism

Technical field

The utility model relates to a kind of Door lock handle mechanism, particularly a kind of Door lock handle mechanism with rotation protection.

Background technology

Existing handle lock is to control bolt by the rotation handle, and generally can only press down direction of handle, the anglec of rotation of well-known handle is limited, and handle rotation stopping means survivability is limited, just in case occur causing Door handle to be scrapped because the handle rotation excessively causes damage will affect user's use even handle cannot be controlled bolt again.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of mechanical door lock handle mechanism with rotation protection.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of mechanical door lock handle mechanism, comprise handle and handle rotating shaft, the described handle rotating shaft other end is equipped with handle location meson, described handle location meson is arranged with spacing block set, meson both sides, described handle location are provided with door lock limited block group, and wherein said door lock limited block group has for the stopper slot that limits the spacing block set scope of activities.

In order to realize the back locking function of Door lock handle, meson below, described handle location is provided with meson lock banking stop movable up and down, the spacing block set lower end of wherein said handle location meson has locks groove, and corresponding position of locking groove, described meson lock banking stop upper end is provided with locks projection.

The beneficial effects of the utility model are: this Door lock handle structure is by rational structure of modification, the particularly design of door lock limited block group, realization presses down handle or the counter restriction of carrying pendulum angle, structure is lightly simple, and installation and maintenance is all very convenient, applicable various common handle locks, the anti-door lock of carrying of handle particularly, by the setting of meson lock banking stop, effectively strengthen antitheft intensity in addition, have good practical value.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is structural representation of the present utility model.

The specific embodiment

With reference to Fig. 1.A kind of mechanical door lock handle mechanism, comprise handle 11 and handle rotating shaft 1, described handle rotating shaft 1 other end is equipped with handle location meson 2, described handle location meson 2 is arranged with spacing block set 21, meson 2 both sides, described handle location are provided with door lock limited block group 3, wherein said door lock limited block group 3 has for the stopper slot 31 that limits spacing block set 21 scopes of activities, be that door lock limited block group 3 is under the prerequisite that does not directly stop meson 2 rotations of handle rotating shaft 1 and handle location, limit the scope of activities of spacing block set 21 by stopper slot 31, thereby limit the anglec of rotation of handle 11, avoid in use handle 11 to rotate through to spend and suddenly cause damage.

Handle 11 is mounted on the Door lock casing by handle location meson 2, and handle 11 rotates synchronously with handle location meson 2, and is subjected to the effect of door lock limited block group 3, and handle 11 is pressed down or the anti-angle of oscillation of carrying carries out angle limits.

Meson 2 belows, described handle location are provided with meson lock banking stop 4 movable up and down, spacing block set 21 lower ends of wherein said handle location meson 2 have locks groove 22, the position that described meson lock banking stop 4 upper end correspondences are locked groove 22 is provided with locks projection 41, when door lock is in when locking state, meson lock banking stop 4 snaps in to be locked in the groove 22, and handle 11 is namely by meson lock banking stop 4 locking splines.

Number that it should be noted that handle location meson 2 is not limited to two, and locks projection 41 and insert under the prerequisite of locking groove 22 even can be arranged to one not affecting, and its principle is identical with foregoing description, belongs to equally within the protection domain of present technique.

The utility model is realized handle 11 is pressed down or the counter restriction of carrying pendulum angle by rational structure of modification, the particularly design of door lock limited block group 3, and structure is lightly simple, and installation and maintenance is all very convenient.
