Abstract
The utility model discloses a protection device of a key cylinder of a mortice door lock. The protection device comprises a bottom plate. A protruding part for containing the end portion of the key cylinder of the mortice door lock is disposed on the bottom plate. A rotating piece is arranged on the protruding part, and an opening corresponding to a key hole on the key cylinder of the mortice door lock is disposed on the rotating piece. The protection device further comprises at least one base plate which can be sleeved on the key cylinder of the mortice door lock and fits the key cylinder of the mortice door lock. Due to the base plate disposed between the bottom plate and a door sheet, the height of the protruding part on the bottom plate can be designed according to the minimum height of the key cylinder of the mortice door lock protruding out of the door sheet. For the key cylinder of the mortice door lock with a larger height, base plates of various specifications are available for selection or base plates of the same specifications are used for combination so as to adjust the distance between the protruding part and the key cylinder of the mortice door lock to ensure that no space exists in between. Thus, the purpose that the protruding part on the bottom plate is completely matched with the key cylinder of the mortice door lock to prevent thieves from prying the protection device and damaging the door lock easily is achieved.
Description
Technical field
The utility model belongs to lockset, particularly relates to a kind of protector of mortise door lock core.
Background technology
Door lock generally adopts mortise door lock core, in order to protect mortise door lock core, often installs protector additional in the outside of door.The protector of existing mortise door lock core as shown in Figure 1 and Figure 2, comprise with screw 5 and be fixed on base plate 4 on door panel 1, base plate 4 is provided with the protuberance 3 that holds the mortise door lock core end, protuberance 3 is provided with anti-drilling rotatable lamella 2, and it is corresponding with keyhole on mortise door lock core 6 that rotatable lamella 2 is provided with perforate 201.Because the height of the protuberance on protector is to protrude the maximum height design of door panel according to mortise door lock core, therefore, the situation that protector can occur not necessarily fitting like a glove when coordinating with the mortise door lock core of different size, for protruding the less mortise door lock core of door panel height, certain space 7 will occur between rotatable lamella 2 in protector protuberance 3 and the end of mortise door lock core 6, the robber just easily prizes protector and destroys door lock like this.
The utility model content
The purpose of this utility model is to provide the protector of the higher mortise door lock core of a kind of security protection performance.
The technical scheme that realizes the employing of the utility model purpose is as follows:
The protector of the mortise door lock core that the utility model provides comprises base plate, and base plate is provided with the protuberance that holds the mortise door lock core end, and protuberance is provided with rotatable lamella, and rotatable lamella is provided with the perforate corresponding with keyhole on mortise door lock core; Also comprise at least one backing plate that can be enclosed within on mortise door lock core and match with the mortise door lock core profile.
Further technical scheme is:
Also comprise the fixed head that can be enclosed within on mortise door lock core, described fixed head is located in the door panel, described backing plate and base plate are located at outside the door panel successively, and described base plate and backing plate are fixed on described fixed head and door panel integrator with the rivet that passes the door panel or screw.
The beneficial effects of the utility model:
the utility model is owing to being provided with backing plate between base plate and door panel, the height that holds the protuberance of mortise door lock core end on base plate just can protrude according to mortise door lock core the minimum altitude design of door panel, for the mortise door lock core that exceeds this height, can provide the backing plate of plurality of specifications to select or the backing plate of polylith same size makes up, not spacing of distance with the protuberance on regulating base board and mortise door lock core end, reaching the protuberance that makes on base plate coordinates with mortise door lock core fully, prevent that the robber from prizing the purpose that protector destroys door lock easily.
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing.

Fig. 2 is the sectional drawing of the protector of existing mortise door lock core.
Fig. 3 is structural representation of the present utility model.
Fig. 4 is sectional drawing of the present utility model.
The specific embodiment
See Fig. 3, Fig. 4, the protector of mortise door lock core, the backing plate 9 that comprises that base plate 4 and at least one can be enclosed within on mortise door lock core 6 and match with mortise door lock core 6 profiles, base plate 4 is provided with the protuberance 3 that holds mortise door lock core 6 ends, protuberance 3 is provided with rotatable lamella 2, and rotatable lamella 2 is provided with the perforate 201 corresponding with keyhole on mortise door lock core 6; Also comprise the fixed head 8 that can be enclosed within on mortise door lock core 6, described fixed head 8 is located in door panel 1, described backing plate 9 and base plate 4 are located at successively door panel outer end with mortise door lock core 6 and cover, and described base plate 4 and backing plate 9 use are passed the rivet of door panel 1 or screw 5 and are fixed on described fixed head 8 and door panel 1 integrator.
After adopting the utility model protector, the protuberance 3 on protector is complete and mortise door lock core is identical, not spacing between them, and the robber is difficult to sled and falls protector destruction door lock.
