Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure for installing a lock unit of a lock handle device for a pop-out type door used in a vending machine or the like.

[0002]

2. Description of the Related Art A lock handle device for a pop-out type door which is generally used in vending machines is such that an inner cylinder is rotatable and cannot be moved back and forth on a bearing cylinder of a fixed case fixed to the door. Attaching, fixing a stopper plate to the rear surface of the inner cylinder,
The handle is inserted into the inner cylinder in a non-rotatable and slidably slidable manner in a protruding direction by a spring. The lock unit is fitted and fixed in the shaft cylinder, and the shaft cylinder is fixed to the inner cylinder. The lock mechanism locks the rotor of the lock unit in conjunction with the lock mechanism.

Recently, thieves against vending machines tend to be violent, and a tapping screw is firmly screwed into a keyhole of a rotor of the lock unit, and a nail pulling bar is hooked on a head of the tapping screw to pivot the lock unit. A method of pulling out from the cylinder has been used. Since the handle is protruded to a position where the handle can be rotated by violent removal of the lock unit, the door is illegally opened and articles and money stored therein are easily taken away.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lock unit built-in structure which is strong against violent pull-out of the lock unit.

[0005]

Means for Solving the Problems Hereinafter, a description will be given using reference numerals in the accompanying drawings. In a lock unit built-in mounting structure of the present invention, a bearing case 3 of a fixed case 2 fixed to a door 1 is provided. The inner cylinder 4 is mounted so as to be rotatable and immovable back and forth, and a stopper plate 5 is fixed to the rear surface of the inner cylinder 4. , The shaft cylinder 7 is moved and urged in the protruding direction by a spring 8, the lock unit 9 is fitted and fixed in the shaft cylinder 7, and the locking mechanism 10 locks the shaft cylinder 7 with the inner cylinder 4. In the lock handle device for a pop-out type door in which the rotor 11 of the lock unit 9 is interlocked, a thick guard flange 12 is provided on the inner peripheral surface of the intermediate portion of the shaft tube portion 7 over the entire circumference, and the rear surface of the guard flange 12 is provided. An angle regulating projection 13 for regulating the rotation range of the rotor 11 is provided on the A thick angle regulating disk 14 that comes into contact with and separates from the regulating protrusion 13 is fitted to the square shaft portion 11a of the rotor 11,
The peripheral edge of the angle regulating disk 14 is brought into contact with the rear surface of the guard flange 12, and the fixing nut 16 screwed to the screw shaft 11 a of the rotor 11 is brought into contact with the rear surface of the angle regulating disk 14.

[0006]

In the illustrated embodiment, the inner wall surfaces 15a, 15b of the notch 15 of the angle regulating disk 14 come into contact with and separate from the end wall surfaces 13a, 13b of the angle regulating protrusion 13, thereby rotating the rotor 11 at a desired angle. Is regulated at 90 degrees.
The screw shaft portion 11b of the rotor 11 is formed in an oval cross section,
The joint member 17 of the shaft cylinder 7 to the locking mechanism 10 is fitted so as to rotate integrally. A fixing ring 18 is screwed and fixed to the body of the lock unit 9, and a forked leg 21 of a U-shaped locking metal fitting 20 is inserted through two side openings 19 of the shaft cylinder 7 of the handle 6. Two inner projections 2 of part 21
2 is engaged with two outer grooves 23 of the fixing ring 18.

[0007]

As described above, in the lock unit assembly structure of the present invention, a thick guard flange 12 is provided on the inner peripheral surface of the intermediate portion of the shaft cylinder 7 of the handle 6, and the rotor is provided on the rear side of the guard flange 12. An angle regulating protrusion 13 for restricting the rotation angle of the rotor 11 to a certain range is provided, and a thick angle regulating disk 14 which comes into contact with and separates from the angle regulating protrusion 13 is fitted to the angular shaft portion 11a of the rotor 11, and the angle regulating disk 14 Of the rotor 11 is in contact with the rear surface of the guard flange 12 and the fixing nut 16 screwed to the screw shaft 11a of the rotor 11 is in contact with the rear surface of the angle regulating disk 14, so that the violent thief is The guard flange 12 and the angle regulating disk 14 are distorted or broken by the pulling force of the crowbar, and the lock unit 9 is not pulled out, so that a sufficiently high antitheft property can be obtained.

[0008] In the lock unit assembly structure of the second aspect,
Since the outer dimension of the nut 16 is set to be larger than the inner diameter of the guide flange 12, the periphery of the nut 16 comes into contact with the periphery of the angle regulating disk 14 as a backing member,
Becomes even more resistant to the extraction of violent thieves by crowbars.
