Abstract
The invention relates to a lock cylinder for a safety box. The lock cylinder for the safety box is composed of an inner thin plate, a lock cylinder, an outer thin plate, a lock hole cover plate and mounting screws, wherein an outer step at the inner end part of the lock cylinder is welded with the inner thin plate, an outer step of the outer end part of the lock cylinder is welded with the outer thin plate, the outer side of the outer thin plate is provided with the lock hole cover plate, the lock hole cover plate, the outer thin plate and the lock cylinder are fastened into a whole by virtue of the mounting screws, and the inner end part of each mounting screw is screwed into a mounting screw hole of the lock cylinder. By adopting the lock cylinder for the safety box disclosed by the invention, screw joint is more reliable and reasonable, processing technology is simplified, and working efficiency is improved.
Description
Technical field
Type of the present invention 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 type of the present invention 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 type of the present invention; 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.
Type of the present invention not only makes and is threaded more reliably, rationally, has also simplified processing technology simultaneously, has improved operating efficiency.
Description of drawings
Fig. 1 is the front view of type of the present invention.
Fig. 2 is A-A sectional view of Fig. 1.
Fig. 3 is the front view of lock core in the prior art.
Fig. 4 is B-B sectional view of Fig. 3.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment type of the present invention is described further.
As shown in the figure, type of the present invention 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 type of the present invention 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.
Type of the present invention 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 type of the present invention 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.Like the structure of Fig. 2, outer thin plate 4 inside are cement, if thin plate might also not tightened at mounting screw 6 and just pushed up cement mortar 2 having distortion, mounting screw 6 length to have error in process of production, have just solved this problem after changing the structure of type of the present invention 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; Type of the present invention 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.
Claims (2)
1. a safety cabinet is used lock core; It is characterized in that: 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 end, be welded with described in thin plate (1); On the outer step of lock core (3) outer end, be welded with described outside thin plate (4); The outside of thin plate (4) is provided with escutcheon plate (5) outside, and escutcheon plate (5), outer thin plate (4) pass through the fastening one of mounting screw (6) with lock core (3), and the inner end of mounting screw (6) screws in the installation screw of lock core (3).
2. safety cabinet as claimed in claim 1 is used lock core, it is characterized in that: the outer end of said mounting screw (6) embeds in the escutcheon plate (5).
