Abstract

The utility model relates to a prizing-proof door which has the main structure that the door is connected with a door frame 1 by an upper and a lower door pivots 11 and 8 and slotted holes 12 arranged on the upper part and the lower part of a door plate 2, a slide way 10 is arranged in the hollow door plate 2, and triangular towing brackets 7 and bearings 9 are fixed on the lower door pivot 8; thus, the door plate 2 can be driven by a key to cause both sides of the door plate to be completely inlaid in grooves of the door frame 1 by pulling and pushing. The door plate, a lock hook 5 and a lock plate 6 work together to perform the function of double locking in all-direction. A lock core protecting sleeve 13 made of rcw 12 material is arranged outside the lock core 4. The hardness of a stopping sheet 17 is within the range of 58 DEG to 60 DEG, so the door can not be damaged by a drill bit. The utility model has the advantages of simple structure, flexible opening, safety protection and high reliability.

Description

A kind of anti-forcing open the door

The utility model relates to a kind of anti-forcing open the door.

At present, the kind of the security door of selling on the market is a lot, though constantly retrofit, its basic structure does not also break away from traditional hinge typed structure, and all is a locking.Existing advanced anti-forcing open the door also is nothing but to have increased several places lock point more, do not have the precautionary measures on the door lock, should give the offender with opportunity, and the place might break door at the lock point.

For overcoming the deficiency that existing security door exists, the purpose of this utility model is, change the traditional hinge typed structure of old-fashioned security door, design a kind of novel from door to the comprehensive strick precaution of lock and prevents forcing open the door.

Technical solution of the present utility model is, be provided with below in hollow door-plate and be used for the bearing bracket mechanism of supporting drive door-plate, door-plate is fixed on door-plate on the doorframe of flute profile by slotted hole and the upper and lower door-hinge that the upper and lower frame of door-plate is provided with, push away, under the effect of pulling force, door-plate can slip in the stile groove of doorframe.The whole of door-plate both sides enter in the doorframe, and Anti-drilling lockwork protective sleeve and rotatable catch with jam plate, latch hook and the lock core of door lock is provided with outward constitute comprehensive large-area locking together.

For anti-structure of forcing open the door of the present utility model is had further understanding, details are as follows in conjunction with an embodiment of the present utility model:

Embodiment, a kind of anti-forcing open the door

Accompanying drawing 1 is a kind of anti-structural representation of forcing open the door.

Accompanying drawing 2 is the vertical view of accompanying drawing 1.

Accompanying drawing 3 is the structural representation of door lock locking state.

Accompanying drawing 4, the structural representation of lock core protective sleeve 13 and catch 17.

With reference to accompanying drawing, the structure of a kind of prized up-proof door of the present utility model has comprised the doorframe 1 among the figure, Door-plate 2, door lock 3, lock core 4, jam plate 6, lower door-hinge 8, upper door-hinge 11, connecting rod 14, it also wraps Having drawn together two that the latch hook fixed head 15 that is welded with in the stile groove of doorframe 1 both sides is provided with can put in Two latch hooks 5 in door-plate 2 lateral opening holes, the door-hinge 8 below hollow door-plate 2 is interior is connected and fixed Two bearings 9 that are fixed wtih on the triangle bracket 7 of contact with bearing 9 and to operate in 2 on door-plate and establish The slideway 10 that has, what be respectively equipped with at the upper, lower horizontal frame of door-plate 2 connects with upper and lower door-hinge 11 and 8 The slotted hole 12 that connects, the lock core that is fixed on the door-plate 2 by hold-down nut 16 outside lock core 4 is protected Cover 13, the rotatable catch 17 and the lock core 4 that are provided with between lock core 4 and lock core protective sleeve 13 revolve Turn to the lock moving plate 18 of drive, and the jam plate fixed head 19 that is welded with at the Men Biannei of door-plate 2 forms.

Wherein doorframe 1 adopts the thick iron plate of 3mm to be pressed into grooved, and the groove of two stiles is relatively inside, The groove of upper, lower horizontal frame is opposite, and outerplanar is relatively inside.

Door-plate 2 is hollow, and the two-ply of heat-preservation cotton is equipped with in the centre.The triangle bracket 7 that the below is provided with in the door-plate, bearing 9, supporting drive door-plate 2 slide on slideway 10 in the distance of slotted hole 12, the both sides of door-plate 2 all embed in the groove of doorframe 1 at closing time, and it has constituted dual omnibearing locking with latch hook 5, jam plate 6.

Lock core protective sleeve 13 and baffle plate 7 adopt the steel plate of rcw12 material, and hardness can reach 58 °-60 ° after the heat treatment, does not destroy with drill bit.

When the open and close door, available key pulling door-plate, the direction of leaving the position of lock or sliding to lock enters in the doorframe, good door lock with key.

A kind of anti-forcing open the door of the present utility model changed the hinge typed structure of traditional security door, adopts inner bearing, the door-plate damascene structures of bracket formula.Be characterized in, simple in structure, the dual locking of door-plate and latch hook, lock core protective sleeve and rotatable catch anti-drilling further guaranteed safety precaution again, and be perfectly safe.
