In the pop-out type lock handle device in which the lock unit 9 is fitted and fixed to the handle shaft portion 7a by being inserted and urged forward by the spring 8, the cylinder portion 9 of the lock unit 9 is provided.
a is formed in an oval body 10 having an oval cross section, an oval hole 11 into which the oval body 10 is fitted is formed on the inner peripheral surface of the central portion of the handle shaft 7a, and the oval body 10 is inserted into the oval hole 11. The lock unit 9 is non-rotatably attached to the handle shaft portion 7a by fitting.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the present invention pertains] The present invention relates to a structure in which a lock unit is incorporated in a pop-out type lock handle device used for a door of a vending machine or the like.

[0002]

2. Description of the Related Art In a conventional pop-out type lock handle device in which a lock unit is incorporated, a cross-sectional shape of a cylinder portion of the lock unit is circular, and a lock insertion hole of a handle shaft portion has a circular shape or a round shape. It is a large circle.

A recent thief has developed a method of threading the lock unit by screwing two tapping screws into the front of the lock unit, forcibly turning the lock unit with the rotary operation tool, and forcibly turning the lock unit. I have. In the above-described conventional lock unit built-in structure, the lock unit can be easily rotated with respect to the handle shaft portion, so that it was difficult to prevent unauthorized unlocking by screw cutting.

[0004]

[Problem to be Solved by the Invention] Accordingly, an object of the present invention is to provide a lock-out unit built-in structure of a pop-out type lock handle device that is resistant to unauthorized unlocking due to thread cutting.

[0005]

Means for Solving the Problems The lock unit built-in mounting structure of the present invention will be described below with reference numerals in the accompanying drawings. The lock unit is mounted on a shaft tube portion 2a of a case 2 fixed to a door 1. The cylinder 3 is mounted rotatably and immovably back and forth, the information member 6 is connected to the rear surface of the inner cylinder 3, and the handle shaft 7 a of the handle 7 is inserted so that the inner cylinder 3 is not rotatable and slidable back and forth. In a pop-out type lock handle device in which the lock unit 9 is fitted and fixed to the handle shaft portion 7a by being urged forward by a spring 8, the cylinder portion 9a of the lock unit 9 is formed in an oval body 10 having an oval cross section. An oval hole 11 into which the oval body 10 fits is formed in the inner peripheral surface of the central portion of the handle shaft portion 7a, and the oval body 10 is inserted into the oval hole 11 to lock the lock unit 9 to the handle shaft portion 7a. Attached so that it cannot rotate relative to You.

[0006] Since the oval body 10 of the lock unit 9 is inserted into the oval hole 11 of the handle shaft 7a, the lock unit 9 cannot be rotated relative to the handle shaft 7a. Will be suspended.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the illustrated embodiment, a fixing ring 13 in which a threaded portion of a cylinder portion 9a of a lock unit 9 is threaded on an inner peripheral surface to form two peripheral grooves 12 on an outer peripheral surface. The lock unit 9 is inserted into the handle shaft 7a, and a U-shaped ring lock 16 having a pair of legs 15 formed with two circumferential projections 14 to be engaged with the circumferential groove 12 is attached to the handle shaft. The lock unit 9 is fixed to the handle shaft 7a by inserting the cylinder 9a from above and below by inserting it into the opening 17 on the side surface of the handle 7a and screwing the cylinder 9a into the handle shaft 7a with mounting screws 18.

Since the fixing ring 13 and the ring lock 16 fixed to the lock unit 9 are engaged in the step portion 19 forming the oval hole 11 in the handle shaft 7a, the mounting position of the lock unit 9 is stabilized. , Further increasing the assembly strength.

[0009]

[Effect of the invention]

 As described above, in the lock unit assembly structure of the present invention, the cylinder 9a of the lock unit 9 is formed in the oval body 10 and is inserted into the oval hole 11 in the handle shaft 7a. The lock unit 9 is assembled so as not to rotate with respect to the handle shaft 7a, and is resistant to unauthorized unlocking due to threading of the lock unit 9.
