Abstract
The utility model discloses an auxiliary safety mechanism of a large-handle lock, which comprises a tripod-shaped safety disc and a torsion spring, wherein the tripod-shaped safety disc and the torsion spring are both sheathed on a rivet column of a fixed driving mechanism, the tripod-shaped safety disc props against a positioning piece, one end of the torsion spring props on the side wall of a panel, the other end thereof is designed in the way that the hook end is hung on one foot of the tripod-shaped safety disc; when a lock cylinder is unlocked, a locking piece pushes the tripod-shaped safety disc away to lead a button to realize the function of opening the door; and when the lock cylinder is locked, the locking piece resets, and the tripod-shaped safety disc returns to the position propping against the positioning piece under the action of the torsion spring, therefore, the auxiliary safety mechanism enhances the safety strength that the large-handle lock locks the button by virtue of the lock cylinder, and improves the anti-destroy capability of the button.
Description
Affiliated technical field
The utility model relates to a kind of insurance institution of big grip handle lock, especially a kind of auxiliary insurance institution of big grip handle lock of head with lock.
Background technology
In the market also do not have a this big grip handle lock by the tapered end safety button.
Summary of the invention
The technical scheme of the utility model technical solution problem is a safety plate of cover and torsion spring in fixed conveyor mechanism.Safety plate is designed to tripod shape, and a pin withstands on the panel sidewall, and pin withstands the spacer on the transmission mechanism, plays auxiliary safety effect, and the another pin is used for being stirred by the locking plate on the tapered end; Torsion spring one end withstands on the sidewall of panel, and the other end is designed to hook-type and hangs on the pin of safety plate, and safety plate is resetted.Locking plate can be pushed safety plate aside when opening tapered end, and a pin that withstands spacer is got out of the way, and button realizes opening the door function; During with the tapered end locking, along with locking plate resets, torsion spring resets the shape safety plate, returns to the position of withstanding spacer again.
The beneficial effects of the utility model are that this auxiliary insurance institution has strengthened the insurance intensity of big grip handle lock by the tapered end lock-down button, has improved the survivability of button.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
As shown in Figure 1, structure of the present utility model is cover safety plate 4 and a torsion spring 5 on the riveting post 7 of fixed conveyor mechanism 8.Safety plate 4 is designed to tripod shape, and a pin withstands 3, one pin of spacer and withstanding under the effect of torsion spring 5 on the panel sidewall, the another pin be used for locked 2 stir, to realize insurance and to remove insurance.One end of torsion spring 5 is designed to hook-shaped, hangs on the pin of safety plate 4, and the other end withstands on the sidewall of panel.Be in locking states at tapered end 1 and promptly be enclosed within locking plate 2 on the lock core when vertical, the spacer 3 that is riveted on the square bar 6 is spacing, i.e. safety position, safety plate 4 withstands spacer 3, plays a part auxiliary insurance.
The course of work: open tapered end 1, be enclosed within locking plate 2 on the lock core and turn over certain angle and safety plate 4 is pushed aside, a pin that withstands spacer is got out of the way, at this moment can press button 9 and open the door; During locking tapered end 1, locking plate 2 goes back to original position again, and safety plate 4 also goes back to original position and is about to the position that spacer 3 withstands under the effect of button spring 5 simultaneously.
