Abstract

The invention discloses a protection device of a mortise door lock plug. The protection device comprises an inner fixed plate and an outer fixed plate which are respectively installed inside and outside the outer panel of an antitheft door and are arranged at the first plug installation hole of the outer panel. A second plug installation hole which is fit with the external form of the mortise door lock plug is arranged on the outer fixed plate. The outer fixed plate is fixedly connected onto the outer panel of the antitheft door by using rivets or screws. Since the outer fixed plate which is integrally fixed with the outer panel is arranged outside the outer panel of the antitheft door and the second plug installation hole which is fit with the external form of the mortise door lock plug is arranged on the outer fixed plate, after the mortise door lock plug is installed on the outer fixed plate, an effect of reinforcing and fixing the mortise door lock plug can be taken, and even though a plug panel on the outer panel is damaged, a theft is difficult to pry to break the mortise door lock plug and cannot destroy the plug to open the antitheft door.

Background technology

Security door generally adopts mortise door lock core.The versatility that security door is installed and installed well for lockset, there is very large defective, as shown in Figure 1 and Figure 2, the panel 1 of security door A is provided with installing hole 101, mortise door lock core 2 is installed in the installing hole 101, at panel 1 lock core panel (not shown) is installed again mortise door lock core 2 is covered.Because installing hole 101 often greater than mortise door lock core 2, after the lock core panel is destroyed, is easy to mortise door lock core 2 sleds are broken, thereby destroys door lock.

Summary of the invention

The protector that the purpose of this invention is to provide the higher mortise door lock core of a kind of security protection performance.

The technical scheme that realizes the object of the invention employing is as follows:

The protector of mortise door lock core provided by the invention, comprise that the outer panels that is installed in respectively security door is outer and be positioned at outer fixed head on the first lock core mounting hole of outer panels, described outer fixed head is provided with the second lock core mounting hole that matches with the mortise door lock core profile, and outer fixed head is fastened on the outer panels of security door with rivet or screw.

The present invention also comprises the internal fixation plate in the outer panels that is located at described security door, and internal fixation plate is provided with the 3rd lock core mounting hole that matches with the mortise door lock core profile, and described inside and outside fixed head is fastened on the outer panels of security door with rivet or screw.

Beneficial effect of the present invention:

The present invention is owing to being provided with the outer fixed head that is fixed as one with outer panels outside the outer panels of security door, outer fixed head is provided with the second lock core mounting hole that matches with the mortise door lock core profile, after mortise door lock core is installed on the outer fixed head, can play mortise door lock core and strengthen fixing effect, after even if the lock core panel on the outer panels is destroyed, the robber also is difficult to the mortise door lock core sled disconnected, can't destroy lock core security door is opened.

Further specify technical scheme of the present invention below in conjunction with accompanying drawing.
