Abstract

The utility model relates to an anti-prizing rolled gate comprising a door frame 1, a circular shaft 2, a spring 3, a lock plate 4, a pressing plate 5 and an unlocking component 7. An a surface of the door frame 1 is provided with a rectangle hole which is bigger than the lock plate 4. A b surface is provided with an opening used for an unlocking connecting rod 9 to move up and down. A c surface is welded with a base 11. The spring 3 and the lock plate 4 are connected with the base 11 by the circular shaft 2; the pressing plate 5 is provided with the rectangle hole which is bigger than the lock plate 4. The pressing plate 5 is provided with a small circle axis 6 which can rotate automatically. The utility model makes use of the concave and convex characteristic of the gate plate of the rolled gate to lock the gate plate of the rolled gate inside the gate frame. The anti-prizing rolled gate has the advantage of difficult prizing.

Description

The pick-proof rolling-gate

One, technical field:

The utility model relates to a kind of burglary-resisting installation, particularly relates to a kind of Anti-theft rolling door.

Two, background technology:

Rolling-gate has been widely used in different places as a kind of antitheft, practical door.The present commercially available following defective of all kinds of rolling-gate ubiquities: door lock does not have particular design, and theftproof performance is poor, rolling-gate often takes place by sled and stolen situation.

Three, summary of the invention:

The purpose of this utility model is to provide a kind of rolling-gate of anti-theft pick-proof.

The utility model adopts following scheme: include doorframe, circular shaft, spring, locking plate, compressing tablet, the part of unblanking, on doorframe a face, have rectangle hole greater than locking plate, have at the b face and to be used to unblank the up and down opening of connecting rod, be welded with pedestal at the c face, spring, locking plate are connected on the pedestal by circular shaft, have rectangle hole on the compressing tablet, the little circular shaft that can rotate automatically is housed on the compressing tablet greater than locking plate.

The utility model utilizes the concavo-convex characteristics of rolling-gate door sheet, and rolling gate door lock in doorframe, is had the advantage that is difficult for prying open.

Four, description of drawings:

Fig. 1 is an overall diagram of the present utility model;

Fig. 2 is sash structure figure of the present utility model;

Fig. 3 is the part structure chart of unblanking of the present utility model;

Fig. 4 is door chip architecture figure of the present utility model.

Five, the specific embodiment:

With the specific embodiment the utility model is further specified with reference to the accompanying drawings below:

From Fig. 1～Fig. 4 as can be known, the utility model includes doorframe 1, circular shaft 2, spring 3, locking plate 4, compressing tablet 5, roundlet axle 6, the part 7 etc. of unblanking, unblank part 7 by the connecting rod 9 of unblanking, gear 10, lock core, shell is formed, the rectangle hole that has on doorframe 1a face greater than locking plate 4 is used for locking plate 4 ejection activities, have the up and down opening of the connecting rod 9 of being used to unblank at the b face, be welded with the fixedly pedestal 11 of circular shaft 2 at the c face, spring 3, locking plate 4 is connected on the pedestal 11 by circular shaft 2, have rectangle hole on the compressing tablet 5, the roundlet axle 6 that can rotate automatically is housed on the compressing tablet 5 greater than locking plate 4; Locking plate 4 numbers are many, more than 2.

The course of work: rolling-gate door sheet 8 is left behind when opening the door, and rotation key tooth drives lock connecting rod 9 by gear 10 rotations and moves downward, and drives compressing tablet 5 again and moves downward, and the roundlet axle 6 on the compressing tablet 5 flattens locking plate 4 downwards, and rolling-gate door sheet 8 just can upwards draw back; Close the door to rolling-gate door sheet 8 is left behind, rotation key tooth drives lock connecting rod 9 by gear 10 rotations and moves upward, driving compressing tablet 5 again moves upward, rectangle hole on rectangle hole on the compressing tablet 5 and the doorframe 1a face overlaps, locking plate 4 outwards ejects under the elastic force effect of spring 3, the recess that locking plate 4 ejects at rolling-gate door sheet 8, rolling-gate door sheet 8 can not spur downwards, thereby reaches the purpose of locking a door.

Claims (2)
