Abstract
The utility model discloses an anti-explosion shell of a lock cylinder. The anti-explosion shell is fixed on a door sheet to protect the lock cylinder and comprises a plate body, an accommodating cavity with the bottom protruding outwards to accommodate the lock cylinder is formed in the middle of the plate body, a through hole where a key can penetrate through is formed in the bottom of the accommodating cavity, at least three mounting holes are formed in the plate body, and at least two inwards-protruding mounting feet are arranged on the inner side surface of the plate body and provided with screw holes. The anti-explosion shell of the lock cylinder is integrally formed through casting, and has the advantage that the lock cylinder is better protected.
Description
Technical field
The present invention relates to lockset accessory technical field, especially relate to a kind of lock core explosion-proof casing.
Background technology
The theftproof performance of entry door is one of index of paying attention to the most of people.Such as, whether this entry door can bear the unnormal unlockings such as prying open of comparatively violence.But most entry doors often exist pick-proof defect at the position at lock core place.,, for pick-proof, how lock core is protected by a housing.But this housing is many to be fixed by the screw that enters door-plate from outward turning, thereby is very easily pried open, then make outside lock core is exposed to, finally to make lock core be difficult to there is stronger pick-proof ability.
Summary of the invention
The object of this invention is to provide a kind of lock core explosion-proof casing, it has the advantages that better to protect lock core.
The technical solution adopted in the present invention is: lock core explosion-proof casing, it is fixed on door-plate with protection lock core, this lock core explosion-proof casing comprises plate body, the middle part of this plate body is provided with the outwards outstanding accommodating cavity with accommodating this lock core of bottom, the bottom of this accommodating cavity is provided with the through hole passing for key, on described plate body, have at least 3 installing holes, and the inner surface of this plate body is provided with at least 2 inside outstanding installation feet, this installation foot has screw.
Described lock core explosion-proof casing is integrated fusion cast process.
The advantage that compared to the prior art the present invention had is: can better protect lock core.Lock core explosion-proof casing of the present invention is in the time being mounted on door-plate; not only fixed by the screw that Luo is connected on this door-plate from outside to inside; and the screw also passing in the screw that has Luo to be connected on this lock core explosion-proof casing from the inner side of this door-plate is fixed; then increased the destroyed difficulty of this lock core explosion-proof casing, the more effective lock core of having protected.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the perspective exploded view of embodiments of the invention.
Detailed description of the invention
In following examples, inside and outside what is called, be interior external the defining in off position time with door-plate.
Embodiment, as shown in Figure 1: lock core explosion-proof casing is fixed on door-plate 100 with protection lock core 200., this lock core explosion-proof casing is wrapped in the outside of this lock core 200.This lock core explosion-proof casing comprises plate body 10, and the middle part of this plate body 10 is provided with the outwards outstanding accommodating cavity 20 with accommodating this lock core 200 of bottom, and the bottom of this accommodating cavity 20 is provided with the through hole 21 passing for key.Further say, on this plate body 10, have at least 3 installing holes 11.Such as, this plate body 10 is square, four of this plate body 10 bights are respectively provided with an installing hole 11.Like this, in this installing hole 11, be connected on this door-plate 100 through screw and this screw Luo from outside to inside, this lock core explosion-proof casing can be able to preliminary fixing.And the inner surface of this plate body 10 is provided with at least 2 inside outstanding installation feet 12, this installation foot 12 has screw 13.Like this, pass from the inside to the outside screw from the inner side of this door-plate 100 and this screw Luo is connected in this screw 13, this lock core explosion-proof casing can be able to further fixing.Obviously, from inside, fixing mode makes the pick-proof ability of this lock core explosion-proof casing stronger.
Further say, this lock core explosion-proof casing is the material one fusion cast processes such as employing stainless steel, cast iron, thereby has further promoted the pick-proof ability of this lock core explosion-proof casing.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes manual of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
