Meanwhile, the male buckle portion 10 and the female buckle portion 20 may be protected while being fitted in a cover including a synthetic resin, as shown in FIG. 10.

4 to 5, the button 28 is provided in a pair at an eccentric position on the upper surface of the locking plate 24, and the main elastic body 26 is concentric with the button 28 so that the bottom surface of the locking plate 24 It is provided in a pair on both sides. The buttons 28 are arranged spaced apart in the width direction of the locking plate 24, and the bottom of the separate button 28 is fixed in position by engaging the negative and positive angle structure of the upper surface of the locking plate 24, as shown in FIGS. 7 and 8A. As shown in 8a to 8b, the main elastic body 26 is disposed as the bottom of the button 28 on the upper surface of both sides of the locking plate 24, and the button 28 is placed on the top of the locking plate 24 as shown in FIG. , As shown in FIG. 8B, it may be integrally formed to protrude upward from the locking plate 24.

Accordingly, when the pair of main elastic bodies 26 are simultaneously compressed by the pair of buttons 28, the rail hole 24a of the locking plate 24 is allowed to move downward along the rail tube 22a, When the pressing force is biased through one of the buttons 28, the locking plate 24 inclines and the rail hole 24a rubs against the rail tube 22a, thereby restricting the downward linear movement, and forcibly opening and working by external force It prevents the unintentional unlocking of the lock when a button is pressed.

Meanwhile, a hole is formed through the upper cover 21 so that the button 28 is exposed, and when the hook 12 is coupled to the arm buckle part 20, the button 28 is unintentionally pressed and the hook 12 In order to prevent the) from falling out, it is also possible to form a button depressurization unit having a height equal to or higher than the height at which the button 28 is exposed on the upper surface of the upper cover 21 as shown in FIG. 1.

In FIG. 11, the locking plate 24 has a locking protrusion 23 formed on one side of the main elastic body 26, and a sub-elastic body 26a is installed on the upper surface of the other side so that a downward pressing force acts, The elastic force of the sub elastic body 26a is weaker than that of the main elastic body 26. Here, the sub-elastic body 26a is formed of a leaf spring, a coil spring, or an elastic block.

At this time, the sub-elastic body (26a) is provided to press the rear upper surface of the locking plate (24), the locking plate (24) is rotated around the main spring (26) and inclined, the locking protrusion (23) is the locking groove It will prevent the deviation from (11).

On the other hand, as shown in Figure 11 (a), the upper surface of the locking plate 24 and the lower surface of the upper cover 21, as in Figure 11 (b), it is also possible to form a set of grooves in which both ends of the sub-elastic body 26a are locally received.

In FIG. 12, an inward rail piece 24b protruding from the inner circumferential surface of the rail hole 24a in a longitudinal direction and in surface contact with the outer circumferential surface of the rail tube 22a is formed, and a locking plate 24 is parallel to the inward rail piece 24b. ) An outward rail piece 24c that protrudes in the longitudinal direction at the edge and slides along the inner sidewalls of the upper and lower covers 21 and 21' is provided.

At this time, the rail tube (22a) is formed as a rectangular tube, the rail hole (24a) is formed as a rectangular hole, and the upper surface of the locking plate (24) is in a straight line with the inner peripheral surface of the rail hole (24a) as shown in Figure 12 (a). The inward rail piece 24b corresponding to is formed. Further, at the rear end of the locking plate 24, an outward rail piece 24c is formed to protrude parallel to the inward rail piece 24b, and is formed to have a'U'-shaped longitudinal cross-sectional shape as shown in FIG. 12(b).

That is, the operation chamber 22 is divided into front and rear divisions by a rail tube 22a, and a locking plate having a'U'-shaped longitudinal section shape by a combination of inner and outer rail pieces 24b and 24c. (24) As the rear end slides along the inner walls of both sides of the rear compartment of the operation room 22, it guides the up and down linear movement of the locking plate 24 and prevents the inclination of the locking plate 24 by external force. Unintentional unlocking of the lock state is prevented.

In use, the end of the belt 1 is connected to the inside of the rail tube 22a of the male buckle part 10 and the belt fastening part 14 of the female buckle part 20 as shown in Fig. 6(a), and then When the male buckle part 10 is inserted as shown in FIG. 6 (b), the bottom of the hook 12 slides with the locking protrusion 23 of the locking plate 24 so that the locking plate 24 is pressed downward and the main elastic body ( 26) is compressed. And, as shown in Figure 6 (c), when the locking groove 11 of the hook 12 enters to the position corresponding to the locking projection 23, the locking plate 24 is pushed upward and the locking projection 23 is the locking groove It is locked to (11) and locked. At this time, the locking plate 24 is prevented from tilting by an operation structure in which the rail hole 24a is linearly moved in the up and down directions along the rail tube 22a, thereby preventing forced opening by external force.

After that, when separating the arm and male buckle parts 20 and 10, when pressing the pair of buttons 28 at the same time, the locking plate 24 rides on the rail tube 22a while maintaining the horizontal line in a downward direction. As it moves, the locking protrusion 23 and the locking groove 11 are separated, and the locking state is released. At this time, when a pressing force is applied by one of the buttons 28 of the pair of buttons 28, the locking plate 24 inclines and the rail hole 24a rubs against the rail tube 22a, thereby interfering with the downward linear movement. This prevents the unintentional unlocking of the lock when a button is pressed during work.
