Abstract

The utility model relates to a lock cylinder for a safety box. The lock cylinder for the safety box is formed by an inner thin plate, the lock cylinder, an outer thin plate, a lock hole cover plate and an installation screw. The inner thin plate is welded on an outer step on the inner end portion of the lock cylinder, the outer thin plate is welded on an outer step on the outer end portion of the lock cylinder, the lock hole cover plate is arranged outside the outer thin plate, the lock hole cover plate, the outer thin plate and the lock cylinder are integrally fastened through the installation screw, and the inner end portion of the installation screw is screwed in an installation screw hole of the lock cylinder. The lock cylinder for the safety box enables screw connection to be more reliable and reasonable, simultaneously simplifies process and improves working efficiency.

Description

Safety cabinet is used lock core

Technical field

The utility model relates to a kind of lock core, and especially a kind of safety cabinet is used lock core.

Background technology

The general structure of cement strongbox is the special-purpose cement of can in two-layer thin plate, to guarantee the intensity of safety cabinet.Outside the door-plate lock core, cover plate is installed like need; When the restriction that receives space and cover plate size; In the time of can't using the form of riveting nut to increase fixing required screwed hole, generally adopt directly that tapping obtains required screwed hole on thin plate, but exist the short and screw of thread to be difficult for shortcomings such as installation.

Summary of the invention

The purpose of the utility model is to overcome the deficiency that exists in the prior art, a kind of reliability that can increase link is provided, has solved screw and twist the safety cabinet of problem not in place and use lock core.

The technical scheme that provides according to the utility model; Said safety cabinet is used lock core, and it is made up of interior thin plate, lock core, outer thin plate, escutcheon plate and mounting screw, on the outer step of lock core inner end, be welded with described in thin plate; On the outer step of lock core outer end, be welded with described outside thin plate; The outside of thin plate is provided with escutcheon plate outside, and escutcheon plate, outer thin plate and lock core are through the fastening one of mounting screw, and the inner end of mounting screw screws in the installation screw of lock core.

The outer end of said mounting screw embeds in the escutcheon plate.

The utility model not only makes and is threaded more reliably, rationally, has also simplified processing technology simultaneously, has improved operating efficiency.

The specific embodiment

Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.

As shown in the figure, the utility model mainly is made up of with mounting screw 6 interior thin plate 1, lock core 3, outer thin plate 4, escutcheon plate 5.

This safety cabinet is used lock core; It is made up of with mounting screw 6 interior thin plate 1, lock core 3, outer thin plate 4, escutcheon plate 5; On the outer step of lock core 3 inner ends, be welded with described in thin plate 1; On the outer step of lock core 3 outer ends, be welded with described outside thin plate 4, the outside of thin plate 4 is provided with escutcheon plate 5 outside, escutcheon plate 5, outer thin plate 4 and lock core 3 are through mounting screw 6 fastening one; The inner end of mounting screw 6 screws in the installation screw of lock core 3, and mounting screw 6 passes escutcheon plate 5, outer thin plate 4 and lock core 3 from outside to inside successively.

The outer end of said mounting screw 6 embeds in the escutcheon plate 5.

The lock core of the utility model is like Fig. 1, shown in 2.Interior thin plate 1, outer thin plate 4 place on the corresponding positioning step of lock core 3 respectively and firm welding, utilize can funnel 7 gaps all to be full of cement mortar 2, wait for cement mortar 2 dryings.During assembling, with mounting screw 6 escutcheon plate 5 is installed on outside plate escutcheon plate 5, outer thin plate 4 are fixed as one with lock core 3.

The utility model is than conventional lock cylinders mounting structure (like Fig. 3,4), not only makes to be threaded reliably more, rationally, also simplified processing technology simultaneously, improved operating efficiency, specifically can through following some embody:

1, the screw and the threaded engagement degree of depth are bigger, and the reliability of connection increases.It is 2 ~ 3mm that thin plate is used in cement strongbox assembly unit commonly used, and directly the screw length after the tapping is less than normal, and the utility model designs screw after on the lock core 3, and the reliability that is threaded is guaranteed;

2, can solve mounting screw 6 and twist problem not in place.Structure like Fig. 2; Outer thin plate 4 inside are cement; If thin plate might also not tighten at mounting screw 6 and just push up cement mortar 2 having distortion, mounting screw 6 length to have error in process of production, just solved this problem after changing the structure of the utility model into;

3, simplified processing process is increased work efficiency.In the conventional lock cylinders structure, flow in the screwed hole of outer thin plate 4 for preventing cement mortar, outside the inboard cement leakproof sticker 8 when welding (must be fire proofing material in case burn-through) that pastes of thin plate 4; The utility model after the cylindrical of lock core 3 is adjacent to welding with outer thin plate 4, can effectively prevent the cement mortar infiltration after improvement.
