Description

A kind of two-way security door of locking and opening

The utility model relates to a kind of security door, especially a kind of two-way security door of locking and opening.

In existing security door, having a kind of is that " door in door " its structure is on the door of a normal size, be provided with a smaller but wicket that also can make the people bend to pass in and out, this wicket can only be locked from opening the door on one side, and its weak point is except that doing emergent usefulness, the direction of opening the door remains one side, must make the door of two kinds of directions so during fabrication respectively, be to increase cost of production, and using also has inconvenience.

The purpose of this utility model is the security door that will provide a kind of bidirectional opening to lock, and it need not to consider direction in manufacturing and designing process, can both lock and open the door on both direction, and be 4 cohesion style lockings, makes its theftproof performance better.

The purpose of this utility model is achieved through the following technical solutions.

Two groups of totally four " worker " font latch fittings are arranged on the both sides of door-plate, they are located on the doorframe respectively, position and four " worker " font latch fittings corresponding " C " shape latch fitting, mutual obvolvent locking is that straight-bar, curved bar, dead bolt are finished by two groups of little, gear wheels by lock core control interlock between them.Four " worker " font latch fittings all are edge-on shape, are connected the door-plate both sides by the movable doorframe that rotates under the ratchet control to be one in the dead bolt front portion, and its outer flushes with the outer of the inside of door-plate.Be in " worker " font latch fitting of dead bolt front portion and " C " font and lock both corresponding positions and all have one on same straight line, with the interior lockhole and the exterior lockhole of dead bolt coupling.Respectively there is a ratchet corresponding each latch bolt position front portion in doorframe, and the ratchet planar side of ratchet is positioned at movable doorframe and plays position-limiting action, and a ratchet pendulum hole is arranged on the movable doorframe, and ratchet is connected on the sour jujube platform by the work of sour jujube axle, and has added the spring of reset response.

Because after adopting above technical scheme, security door just can be realized two-wayly locking, bi-directional door, and its manufacturing cost reduces, owing to adopt the multiple spot cohesion style to lock, theftproof performance significantly strengthens, and the external force resistance destructive characteristics is comparatively outstanding.

Below in conjunction with accompanying drawing and an embodiment structural principle of the present utility model is further described.

Fig. 1 is the utility model partial cutaway diagrammatic sketch.

Fig. 2 is the assembling schematic diagram of the ratchet part of dead bolt front end, also is A-A face cut-away view among Fig. 1.

In Fig. 1, most of door skin 4, the doorframe 1 showed expose internal construction after cutting open, wherein driving member is such: with lock core 14 is that the pinion 15 of axle can be engaged on the gear wheel 13, both sides up and down at gear wheel 13 are connected with two straight-bars 3 with axle respectively, the end of straight-bar 3 is connected the curved bar 5 at a right angle again by straight-bar axle 17, wherein the curved bar bight has crankshaft axis 18 to be fixed on the inboard door skin 4, the other end of curved bar 5 has the slideway 12 of a vertical direction, connect a dead bolt 6 by the dead bolt axle on the slideway 11, dead bolt 6 major parts place 19 li in dead bolt slideway.

Pinion 15 will drive gear wheel 13 rotations when inserting key in the lock core 14 and rotating, straight-bar 3 one ends on gear wheel both sides about in the of 13 have the swing of certain spoke degree, and generation moves up and down, spurring curved bar 5 simultaneously is that rotate in the axle center with crankshaft axis 18, curved bar 5 ends can be stirred the dead bolt axle 11 or the right side or move left, dead bolt 6 will or advance in dead bolt slideway 19 or go out so, promptly can pass exterior lockhole 24, interior lockhole 25, as shown in Figure 2: in dead bolt 6 advances process inwards, will be dead door lock, just " worker " font latch fitting 7 and " C " shape latch fitting 8 locked being in the same place, and then when advancing inwards, will pass ratchet 21, make ratchet 22 leave movable doorframe 29, will be reference with Fig. 1 at this moment, door-hinge 10 with the left side is an axle, door is just opened on the right, otherwise door has been opened with regard on the left side.Close in front of the door ratchet 21 and reset earlier under back-moving spring 26 effects, at closing time, movable doorframe 29 can be slowly near the ratchet arcwall face, and slips over from it, returns to Fig. 2 position at last.

From the above description as can be known, this door can be opened from the left side respectively, also can open from the right, but a Here it is bidirectional opening, the embodiment that locks.

Claims (4)

1, a kind of bidirectional opening security door of locking, it is to be linked to each other by one group of hingen by steel door frame and door-plate to constitute, and locked at the multiple spot of door, it is characterized in that: two groups of totally four " worker " font latch fittings (7) are respectively arranged on the both sides of door-plate, this door is located on respectively that doorframe (1) is gone up, position and four " worker " font latch fittings (7) corresponding " C " shape latch fittings (8), between them mutually the obvolvent locking be to finish by little, gear wheel (15) (13), straight-bar (3), curved bar (5), dead bolt (6) that two groups of lock cores (14) control links; In dead bolt (6) front portion be one by ratchet (21) the control movable doorframe (29) of rotation down.
