Reference numeral 1 is a box body usually made of metal, 2 is a surrounding wall portion constituting the box body 1, and a case 3 is attached to the outer surface. wear it. Reference numeral a designates a lock body made of a metal plate that is mounted inside the case 3, and the lower end portion 4 is formed with a lock claw portion 5 that is bent horizontally inward. 6 is located above the claw part 5, and the case 3
The pin 6 is attached to the inside of the spring 7, and one end of the spring 7 is inserted into the pin 6. and spring 7
The other end is fitted into a recess 8 formed above the claw portion 5. In order to form the recess 8, since the lock body a is made of metal plate, a hole is punched out using a press, and a plate is applied to the back surface.
11 is a case 3 on the outside of the upper end 9 of the lock body a.
Connected to the operating handle 10 that protrudes further,
In addition, it is a shaft supported on both left and right sides of the case 3, and a cam 12 that constantly resists the spring 7 is attached above the shaft 11. 13 is lock a
The curved part bulges outwardly between the recessed part 8 and the upper end part 9, and the curved part 13 has a case 3.
A pin 14 supported on both left and right sides of the shaft is inserted and positioned between the lower spring 7 and the upper shaft 11 to serve as a fulcrum. 1
Reference numeral 5 denotes a bottom frame, 16 a bottom plate, and 17 a reinforcing portion having a cross-sectional shape and fixed to the lower outer side of the claw portion 5 having a vertical cross-section.

ながら爪部５がボトムフレーム１５を支止する。 Next, to explain the operation of the present invention, when the operating handle 10 is pulled from the state shown in the second figure in which the bottom plate 16 is locked, the shaft 11 rotates around the pin 14 in proportion to the rotation range of the handle 10. At the same time, the cam 12 fixed above the shaft 11, which was resisting the spring 7, also rotates.
1, and the claws 5, which are pressed by the springs 7, simultaneously rotate outward and come off the bottom frame 15, opening the bottom plate 16. At this time, the shaft 11 and cam 12 are connected to the lock body a.
Since the spring 7 rotates while being located above the pin 14 constituting the spring 7, even the spring 7 with a large pressing force can be opened extremely easily. The spring 7 is fitted into the recess 8 and will not come off. In the case of the present invention, the operating range of the cam 12 is 45 degrees. Note that the bent inner surface of the claw portion 5 is formed into a horizontal plane so that it can be smoothly engaged with the bottom frame 15. Furthermore, even when the bottom frame 15 is subjected to a considerable load of the items stored in the box body 1 on the claw portion 5, the strength is maintained by the reinforcing portion 17 attached to the outer surface of the claw portion 5. At the same time, the claw portion 5 supports the bottom frame 15.

いる。(1) In the present invention, a pin that serves as a fulcrum is attached to the upper end of the lock body, and a cam is located between the pin and the spring to release the pawl part of the lock body against the spring. This is significantly different from the conventional lock mechanism, in which the fulcrum pin is mounted directly above the spring, and the cam is mounted at the top end of the lock body, so the lock body is attached to the claw part. The load on the handle, that is, the pressing force required for the lock to expand outward from the locked state and open the bottom plate, is the load on the handle that constitutes the conventional lock mechanism (Japanese Patent Publication No. 52-23489). Therefore, the workability after lifting the dust box is extremely good, and the degree of fatigue can be significantly reduced compared to the conventional method.

減できる等の利点を有している。(2) Furthermore, with the present invention, the height of the shaft on which the cam is mounted can be mounted at a significantly higher position than that of conventional lock mechanisms, and the handle connected to the shaft can also be made higher in proportion to the shaft.
It has the advantages of being extremely easy to grip during work and reducing fatigue.

において著しい、差異点がある。(3) In addition, the present invention has a shape on the outer surface of the claw portion.
Since a reinforcing portion having a square-shaped vertical cross section is attached, even if the claw portion is pressed by the bottom frame, the fear of breakage can be eliminated. The claw portion of the conventional locking device (Japanese Patent Publication No. 52-23489) does not have a reinforcing member, and there is a significant difference in the construction of the claw portion between the two devices.
