Description

Concealed protects the lock security door

The utility model relates to security door manufacturing technology field, and exactly it is that a kind of concealed protects the lock security door.

At present, the lockhole of two built-in locks all significantly is exposed on the shop front on the security door of selling on the market, be easy to that naughty or evil person sends out the bad lockhole that stops up or destroy by child, also being opened built-in lock by the robber with the key that duplicates easily enters the room, in order to address this problem, people have developed lock-protector again, adopt the way of sticking plaster, and lock-protector is fixed on the shop front with several Screws.The panel of door is the iron plate of 1.2 millimeters thick, and Screw two or three button of can only screwing on dare not be tightened at all and be afraid of to destroy screw thread, and very insecure, its tamper-proof function is very low, and its economy, practicality all do not reach people's ideal.Existing in addition security door is to realize the horizontal and vertical locking of door with two locks, the comparatively trouble of opening the door.

The utility model purpose provides a kind of security door that protects the backset plate that has, and the protection lockhole is not artificially stopped up, and protects the stopper plate and opened by coded lock, promptly realizes laterally and vertically locking of security door with a lock simultaneously.

The purpose of this utility model is achieved by the following scheme; it is by built-in lock; coded lock; doorframe; door face board; folding and peephole are formed; it is characterized in that: coded lock and built-in lock (1) all are contained on the installing plate (2); built-in lock (1) by screw (3) be fixed on the lock frame (19) above; the fore shaft surface of built-in lock (1) is recessed in the lockhole of door face board (18); on built-in lock (1) fore shaft surface, float to be equipped with and protect the stopper plate; it is between the lockhole end face and device protection liner plate (20) of built-in lock (1); two sliding trays are arranged above it; two slide blocks (25) riveted is arranged in the groove on installing plate (2); protecting the tail end perk part of stopper plate (13) passes from the open-work of installing plate (2); relative with the center of coded lock; dead bolt (50) is welded to connect with tooth bar (4); tooth bar route of retreat buting iron (5) is housed on the tooth bar (4); tooth bar (4) and gear (61) engagement; gear (61) is fastened together by bearing pin (41) with gear separator (38) and gear (36); be installed on the gear shaft (42); gear shaft (42) is fixed on the installing plate (2) by nut (35); gear (36) meshes with two identical tooth bars (16); all gears; tooth bar all is housed in the gearcase (7); gearcase (7) is fixedlyed connected with installing plate (2) by screw (8), and the two ends of gearcase (7) have rack slide and are pickled with grains or in wine.Protect and stud with quenching anti-drilling board (23) on the stopper plate (13).The luminous body (44) that transparent plastic is made is equipped with in coded lock figure disc (29) inside; light emitting diode (27) is housed in the luminous body; figure disc has loophole on (29); luminous body (44) is fixed on the location-plate (28) by tapping screw (43), and location-plate (28) and figure disc (29) use screw (33) to be fixed on the protection liner plate (20) simultaneously.

The utility model has the advantages that; owing to installed additional on the security door and protected the stopper plate, can effectively protect lockhole artificially not stopped up, stud with the quenching anti-drilling board on the stopper plate owing to protecting in addition; and must open by coded lock, thereby can prevent effectively that the robber from utilizing electric drill to force open the door and pressing lock.The utility model both can have been realized laterally and vertically locking of security door with a lock, around the lock lighting device was housed also, and security door itself also is equipped with electric bell, for the user provides bigger convenience.

Below in conjunction with drawings and Examples the utility model is described in further detail.
