DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The latch lock of the present invention will be described below in detail with reference to the drawings shown as an embodiment. As shown in FIG. 1, the latch lock of the present invention comprises an outer cylinder 2 integrally provided with a lid opening / closing knob 1, a latch holder 3 attached to an end of the outer cylinder 2, and the lid opening / closing knob. It is composed of a latch lever 4 attached to the lower part of 1.

The lid opening / closing knob 1 is provided with a flange 5 at the connecting portion with the outer cylinder 2, and a mounting groove 6 for the latch lever 4 is formed from the lower side surface to the inside. The mounting groove 6 communicates with the inside of the outer cylinder 2. The outer cylinder 2 is formed with a fitting groove 8 for fitting the fixing ring 7 into a connecting portion with the lid opening / closing knob 1, and the mounting grooves 9, 9 of the latch holder 3 and one The latch projecting / retracting groove 10 is formed continuously with the mounting groove 9 of FIG.

As shown in FIG. 2, the latch holder 3 is provided with a latch moving hole 11 and a spring chamber 12 connected to the latch moving hole 11.
A vertical groove 13 is formed on the side wall of the latch moving hole 11, and the convex portion 15 of the latch 14 housed in the latch moving hole 11 is fitted into the vertical groove 13 to allow the latch 14 to move and rotate. Together with the spring 1 housed in the spring chamber 12.
The contact portion 17 of the latch 14 projects from the latch holder 3 while being biased by the spring 6. In addition,
The back portion 17 of the latch 14 has a curved portion 17a on the back side and a straight portion 17b on the front side.

A spring chamber 18 is formed in the latch lever 4, a hanging hole 19 is formed at the outer end, and a contact portion 20 is formed at the inner end. The latch lever 4 is inserted from the mounting groove 6 of the lid opening / closing knob 1 into the outer cylinder 2 and is pivotally supported by a pin 21 at one end of the outer cylinder 2. It is close to the latch moving hole 11. The latch moving hole 11 and the contact portion 20 are positioned on the same plane in a state where the latch lever 4 is not operated, that is, in a state where the latch lever 4 is pushed back by the spring force of the spring 22 housed in the spring chamber 18. The latch moving hole 11 and the contact portion 20 are not located on the same plane in a state where the latch lever 4 is operated, that is, in a state where the latch lever 4 is pressed against the spring force of the spring 22.

In the latch lock of the present invention constructed as described above, the outer cylinder 2 is inserted into the mounting hole (not shown) provided in the lid 31 of the box 30 such as a collecting post, and the lid opening / closing knob 1 is inserted. By bringing the flange 5 into contact with the lid 31 and fitting the fixing ring 7 into the fitting groove 8 formed in the outer cylinder 2,
It is attached to the lid 31. Thus, when closing the lid 31 to which the latch lock is attached, the curved portion 17a of the contact portion 17 of the latch 14 is locked by the locking body 30a in the box 30.
Then, the latch 14 moves in the latch moving hole 11 and the contact portion 17 of the latch 14 sinks into the latch holder 3 to get over the locking body 30a and at the same time the spring force of the spring 16 causes the latch 14 to return to its original position. The state is returned to the state shown in FIG. In this state, as shown in FIG. 5, since the latch moving hole 11 and the contact portion 20 of the latch lever 4 are located on the same plane, the lid opening / closing knob 1 is pulled without operating the latch lever 4. However, the latch 14 does not rotate against the contact portion 20, the contact portion 17 of the latch 14 remains locked to the locking body 30a in the box 30, and the lid 31 cannot be opened. Then, in this state, the latch lever 4
If a padlock 32 is attached to the hanging hole 19 of this, the latch lock of this invention is locked and the lid 31 can be kept in a closed state.

Next, when opening the lid 31, the padlock 32 is removed from the hook hole 19 of the latch lever 4,
As shown in FIG. 6, when the latch moving hole 11 and the contact portion 20 are not located on the same plane by operating the latch lever 4, the latch 14 does not contact the contact portion 20 and is rotatable. In this state, if the lid opening / closing knob 1 is pulled, the corresponding portion 17 of the latch 14 will be the locking member 3 in the box 30.
Since the latch 14 rotates upon hitting 0a, the locked state is released and the lid 31 can be opened.

[0013]

The latch lock of the present invention is constructed as described above, and since the padlock 32 can be attached to the hook hole 19 of the latch lever 4 without operating the latch lever 4, it can be locked. The operation of installing the padlock 32 has become easier. In addition, the latch lock of this invention is a lid
The latch lever 4 is attached to the bottom of the opening / closing knob 1.
Attached to the latch hole 19 of the latch lever 4.
The padlock 32 that can be removed becomes inconspicuous and has a good appearance.
It will be good.
