Abstract

The utility model discloses an expansion safety bolt, which comprises a steel bar bolt, a steel pipe, a spring, a positioning sheet steel, a steel cable, a soft spring pipe, an indoor handle, a handle, a connecting rod, a clamping head, and a winding ring. The positioning and the rotation of the connecting rod are controlled by the bolt of the built-in lock. The connecting rod and the winding ring are driven by the rotation of the indoor handle or the handle. The steel cable is driven by the winding ring, and then the steel bar bolt is driven to be expanded and contracted to realize the locking of the door or the unlocking of the door. Under condition that the handle is not rotated by the external force, the steel bar bolt extends out under the action of the elastic force of the spring, and the door is locked. Because the steel cable between the built-in lock and the bolting is served as a driving member, the locking point can not be seen outside door, in addition, two locking points are provided, and therefore, the door is provided with the insurance function and the reinforced function.

Description

Expansion safety bolt

The utility model relates to the insurance lockset, relates in particular to the telescopic type johnny bar that matches with built-in lock and bolt.

The lockset of prior art, picking lock or force open the door than being easier to even use built-in lock, is also opened by crack between a door and its frame with hard sheet and simple cutter easily.

The purpose of this utility model is to overcome the deficiencies in the prior art part, provides on a kind of basis of the built-in lock in prior art, and with the insurance lockset that bolt is linked, key effect is that the robber touches less than locking a door a little.

The said telescopic type johnny bar of the utility model includes the wrapping wire circle of built-in lock lock body, bolt, wire rope and pulling wire rope and seals tube.Bolt adopts steel pipe manufacturing, and its length equates with the width of door.At the two ends, center of bolt a spring and reinforcing bar dead bolt are housed respectively, open a kerf at the center, difference stationary positioned steel disc, with the effect of fixing spring seat and wire rope and the reinforcing bar dead bolt connection effect of playing both sides, match with the reinforcing bar dead bolt, installing keyhole on the doorframe of both sides or punching on the wall on doorframe both sides, the diameter in hole and the degree of depth are advisable with the diameter and the insertion length that are fit to the reinforcing bar dead bolt.Control the location and the rotation of link rod with the basic activity of built-in lock lock body, and then control wrapping wire circle and wire rope, stretching of the reinforcing bar dead bolt at pulling bolt two ends can realize locking a door and opening the door.

Adopt the said johnny bar of the utility model, because with the moving wire rope of wrapping wire astragal, drive the reinforcing bar dead bolt again, so, the installation setting of built-in lock and bolt need be at a position, and again because bolt is horizontal, and the control position of wire rope and wrapping wire circle and built-in lock dead bolt is closed, so opposite house has played certain reinforcement effect, because differing, the installation of bolt and lock cause people not observe the position of locking a door again outdoors.For the built-in lock that makes our normally used various models still can use, the circulator of 5 to 6 gears can be set, cooperate installation with the wrapping wire circle, gear is made up of 8 to 14# screws, and owner can select for use arbitrarily.

Adopt the said johnny bar of the utility model, also can use flexibly in the use, single door be used also bolt can be blocked from the center, be separately fixed at two positions up and down of the direction of locking a door, the unification of reinforcing bar dead bolt has made it two and has locked a door a little towards the direction of locking a door.To the use of double door, also bolt can be blocked from the center, be separately fixed at the fixedly keyhole of the reinforcing bar dead bolt unification of position up and down on other Yishanmen of Yishanmen.

Accompanying drawing 1 and accompanying drawing 2 are the schematic diagrames that meet the utility model theme, and Fig. 1 is the structural representation of the said telescopic type johnny bar of the utility model, and Fig. 2 is the Rotation Controllers schematic diagram of the said telescopic type johnny bar of the utility model.

Referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows in conjunction with the embodiments:

Reinforcing bar dead bolt (1) is used for inserting the keyhole on the doorframe, also above-mentioned keyhole can be installed on the wall of both sides.If the double door structure, also keyhole can be fixed on and be equipped with on the Yishanmen in addition of this Yishanmen symmetry of reinforcing bar dead bolt (1).Blind nut (2) is used for fixing reinforcing bar dead bolt (1) and is not ejected by spring (4).Steel pipe (3) is a hollow section, in spring (4) and reinforcing bar dead bolt (1) are arranged, steel pipe (3) can make reinforcing bar dead bolt (1) fixed-direction slide.Spring (4) is contained in the steel pipe (3), and an end and reinforcing bar dead bolt (1) join, and the other end is fixed on the location steel disc (5).Location steel disc (5) is used for fixing the soft spring pipe (7) of wire rope (6) on the other hand on the one hand as the positioning support of spring (4).Certainly, said here soft spring pipe (7) also can replace with the pipe of common steel tube or other materials.Here said soft spring pipe (7) is just passable as long as can protect wire rope (6) not expose.One termination reinforcing bar dead bolt (1) of wire rope (6), the other end be connected on wrapping wire circle (17) on the dop of one (16), no matter be turning cell inner handle (9) or turning handle (14), can pass through link rod (13) and drive wrapping wire circle (17) rotation, drive wire rope (6), spur in the reinforcing bar dead bolt (1) again and contract, door promptly is opened.Handle loosens, and reinforcing bar dead bolt (1) promptly stretches out under the elastic force effect of spring (4), and door lock is lived.Fixed head (8) is used for fixing bolt at position behind the door.Wire master hole (10) is used for fixing the soft spring pipe (7) of wire rope (6), and wire rope (6) is received on the wrapping wire circle (17) by the centre bore and the dop (16) of wire master hole (10).Sealing tube (11) is used to seal wire rope (6), and the control gear exposes.Nut (12) combines as a whole link rod (13) and wrapping wire circle (17), and screw (15) is used for controlling the gear of reinforcing bar dead bolt (1).

Here said telescopic type johnny bar is not to make restriction, and the built-in lock of repacking prior art is equipped with the said bolt part of the utility model again, installs joystick again additional, also can reach same purpose.
