Abstract

The utility model discloses a 180 DEG opened burglarproof door hinge device. A doorframe (1) is fixed with at least two vertically arranged hinge cover bases (2); the hinge cover bases (2) are provided with coaxial doorframe pivot shafts (10); the doorframe pivot shaft (10) in each hinge cover base (2) is fixed with a doorframe hinge arm (3). A door leaf hinge mount (6) is fixed on the hinge cover base (2) corresponding to a door leaf (7); a door leaf hinge arm (4) is hinged with the door leaf hinge mount (6), via a door leaf pivot shaft (9). The door leaf hinge arm (4) is fixedly connected with the doorframe hinge arm (3). The doorframe pivot shaft (10) in each hinge cover base (2) is provided with a torsion spring (12); one end of the torsion spring (12) abuts on the doorframe (1); the other end abuts on the doorframe hinge arm (3). After adopting the structure, the burglar-proof door can be opened freely from 0 DEG to 180 DEG; the problem that an existing burglar-proof door blocks an aisle when opened is solved. The utility model has the advantages of reasonable and simple structure, convenient door leaf gap adjustment, firm and reliable connection, etc.

Description

The security door hinge means of 180 ° of unlatchings

Technical field

The utility model relates to a kind of security door hinge means, and particularly a kind of security door that makes is opened 180 ° hinge means.

Background technology

Existing security door generally can only be opened 90 °, brings inconvenience in the use work and life, office space particularly, and opening the door office influence the current of passageway, the closing the door office influence effect of handling official business; For this reason, many research units, manufacturer and knowledgeable people develop and study in order to make security door can open 180 °, have done a large amount of work, but do not have better products to emerge so far as yet; Therefore, developing a kind of security door hinge means simple in structure, that can effectively open 180 ° is extremely urgent problem.

Summary of the invention

Can only open 90 ° disadvantage in order to overcome existing security door, the utility model provide a kind of simple in structure, door leaf is easy to adjust, the security door hinge means of 180 ° of unlatchings sequentially.The technical scheme that its technical problem that solves the utility model adopts is to be fixed with vertically disposed two knuckle guard seats on doorframe at least, the knuckle guard seat is provided with coaxial doorframe hinge, be fixed with the doorframe pivoted arm on the doorframe hinge in each knuckle guard seat, be fixed with the door leaf hinge seat on the door leaf corresponding with the knuckle guard seat, the door leaf pivoted arm is hinged by door leaf hinge and door leaf hinge seat, and the door leaf pivoted arm is fixedlyed connected with the doorframe pivoted arm; Doorframe hinge in described each knuckle guard seat (2) is provided with torsion spring, and torsion spring one end withstands on the doorframe, and the other end withstands on the doorframe pivoted arm.

For the ease of regulating door leaf and doorframe gap, the fixing fixing hole of described door leaf pivoted arm and doorframe pivoted arm is an adjustment hole.

After adopting said structure, when door leaf is opened, because torsion spring elastic force effect, make door leaf with the rotation of doorframe hinge, when rotating to 90 °, the doorframe pivoted arm contacts with the M place of doorframe pan, the doorframe pivoted arm is stopped the rotation, when continuing to open, door leaf then rotates to 90 ° around the door leaf hinge, thereby finishes the unlatching of 180 ° of door leafs; At closing time, because torsion spring top power effect, door leaf rotates around the door leaf hinge earlier, when half-twist, the door leaf pivoted arm contacts with door leaf hinge seat N place, and door leaf stops to rotate around the door leaf hinge, when continuing at closing time, door leaf then begins rotating closed around the doorframe hinge, thereby security door can arbitrarily be opened between 0 to 180 °, has eliminated the problem of blocking the passageway when existing security door is opened; Have advantages such as simple and reasonable, door leaf gap adjustment convenience, firm and reliable connection.

The specific embodiment

Fig. 1 is to shown in Figure 4, specific embodiments for the security door hinge means of 180 ° of unlatchings of the utility model, on doorframe 1, be fixed with vertically disposed four knuckle guard seats 2, knuckle guard seat 2 is provided with coaxial doorframe hinge 10, be fixed with doorframe pivoted arm 3 by soket head cap screw 11 on the doorframe hinge 10 in each knuckle guard seat 2, be fixed with door leaf hinge seat 6 by sunk screw 8 on the door leaf 7 corresponding with knuckle guard seat 2, door leaf pivoted arm 4 is hinged by door leaf hinge 9 and door leaf hinge seat 6, door leaf pivoted arm 4 is fixedlyed connected with doorframe pivoted arm 3 by soket head cap screw 5, door leaf pivoted arm 4 is an adjustment hole with the fixing hole that doorframe pivoted arm 3 is fixed, and is convenient to regulate door leaf and doorframe gap; Doorframe hinge 10 in described each knuckle guard seat 2 is provided with torsion spring 12, and torsion spring 12 1 ends withstand on the doorframe 1, and the other end withstands on the doorframe pivoted arm 3.

The course of work of the present utility model is as follows: when door leaf is opened, because torsion spring 12 spring force effects, four doorframe pivoted arms 3 that make door leaf 7 and fixedly connected with door leaf pivoted arm 4 rotate synchronously with doorframe hinge 10, when rotating to 90 °, doorframe pivoted arm 3 contacts with the M place of doorframe pan, doorframe pivoted arm 3 is stopped the rotation, the doorframe hinge 10 of fixedlying connected with doorframe pivoted arm 3 also stops the rotation, when continuing to open, door leaf 7 then rotates to 90 ° around door leaf hinge 9, thereby door leaf 7 is finished 180 ° unlatching; At closing time, because torsion spring 12 top power effects, door leaf 7 is earlier around 9 rotations of door leaf hinge, when half-twist, door leaf pivoted arm 4 contacts with the N place of door leaf hinge seat 6, and door leaf 7 stops around 9 rotations of door leaf hinge, when continuing at closing time, door leaf 7 is along with doorframe hinge 10 half-twist closures, thereby security door can arbitrarily be opened between 0 to 180 °.
