Description
Technical field
The utility model relates to civilian technical field of security, and a kind of door of specific design, particularly relates to a kind of can effectively preventing and pry open from double door junction and the double door with pick-proof sealing function of favorable sealing property.
Background technology
At present, existing double door forms by doorframe and by two door-plates that hinge is connected with doorframe usually, common structure is two door-plates is rectangle platy structure, door lock is provided with between the side that two door-plates are relative, the lateral surface of a door-plate is provided with near the position of the side relative with another door-plate and blocks bar, for blocking, sealing, spacing.But the outside of crack only has one to block bar between two of this double door fan door-plates, door lock can be destroyed easily after lawless person only pries open and blocks bar and enter into indoor, therefore the non-constant of pick-proof security protection performance of the double door of this structure, in addition, gap between two door-plates of the double door that prior art is produced only has one to block bar, substantially cannot the insulating effect that plays of air to external world, the therefore sealing performance of the double door of this structure also non-constant.
Summary of the invention
The purpose of this utility model is exactly the problem in order to solve existing double door pick-proof, poor sealing performance, and provides a kind of can effectively preventing to pry open from double door junction and the double door with pick-proof sealing function of favorable sealing property.
The technical solution adopted in the utility model is:
A kind of double door with pick-proof sealing function, the first door-plate comprising doorframe and be connected with doorframe by hinge and the second door-plate, described first door-plate pass on left gemel connection inside doorframe left part, the right side of described second door-plate by gemel connection inside doorframe right part, the rear wall of described first door-plate is provided with the first groove near the position on right side, described first groove runs through two end faces up and down of the first door-plate, first groove is vertical with two end faces up and down of the first door-plate, the first fin is formed between first inside grooves right side wall and the right side wall of the first door-plate, the front side wall of described second door-plate is provided with the second groove near the position in left side, described second groove runs through two end faces up and down of the second door-plate, second groove is vertical with two end faces up and down of the second door-plate, forms the second fin between the second inside grooves left side wall and the left side wall of the second door-plate, the geomery of described first groove and the geomery of the second fin are wanted to coincide, and the geomery of the first fin and the geomery of the second groove match, be provided with door lock in described first fin, when described door lock closes, its dead bolt extend in the first groove through the left side wall of the first fin, and position just right with the Door-lock bolt in the first fin in the second fin has hole, dead bolt position.
Distance between end face to the first door-plate front side wall of described first fin is 1/2nd of the spacing of the first door-plate front side wall and rear wall.
The right side wall of described first door-plate is provided with first near the position of front side wall and blocks bar, first to block the top of bar concordant with the top of the first door-plate, first to block the bottom of bar concordant with the bottom of the first door-plate, and first to block bar front side wall concordant with the front side wall of the first door-plate.
The left side wall of described second door-plate is provided with second near the position of rear wall and blocks bar, second to block the top of bar concordant with the top of the second door-plate, second to block the bottom of bar concordant with the bottom of the second door-plate, and second to block bar rear wall concordant with the rear wall of the second door-plate.
The beneficial effects of the utility model are:
The double door of what the utility model provided have pick-proof sealing function, groove on two door-plate fastens mutually with corresponding fin, and door lock is arranged on the first fin, door lock dead bolt when locking is made to be stuck between the first fin and the second fin, because the instrument such as crow bar of lawless person cannot from the installation position extending into door lock between the first fin and the second groove, directly cannot cause physical destroy to door lock, therefore greatly improve the tamper-resistant safety performance of double door; Groove on two door-plates fastens mutually with corresponding fin, the gap that an interface is S shape is formed between two door-plates, namely a labyrinth seal is formed at two door-plates, the air gap not easily passed through between two door-plates of door-plate side enters into the opposite side of door-plate, and the sealing performance of double door is improved; Distance between end face to the first door-plate front side wall of the first fin is 1/2nd of the spacing of the first door-plate front side wall and rear wall, can ensure that the second groove on the second door-plate has enough intensity resistance external force, and door lock is more easily installed; Be provided with first at the right side wall of the first door-plate near the position of front side wall and block bar, be provided with second at the left side wall of the second door-plate near the position of rear wall and block bar, need first to destroy to block bar to destroy door lock, therefore the tamper-resistant safety performance of the double door that the utility model provides is promoted further, and two existence of blocking bar make the tortuous prolongation further of the gap between two door-plates, be equivalent to the contact surface extending labyrinth seal, also can promote the sealing performance of the double door that the utility model provides further.
In a word, the double door of what the utility model provided have pick-proof sealing function is rational in infrastructure, has the advantage of better tamper-resistant safety performance and sealing performance.
