Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container lid and a container lid catching device which can be opened and closed with one touch when locking and unlocking the container.

[0002]

2. Description of the Related Art A conventional locking device for a container and a lid uses a hook, in which a main body is attached to the container or the lid and a hook is attached to the other.

However, in such a conventional device,
Locking requires a two-step operation in which the ring of the main body is hung on the hook, and the main body is pulled in the opposite direction to pull the ring and fix the hook.

Further, in the conventional device, in order to unlock, it is necessary to perform two-step operation in the opposite procedure to the locking.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a container lid catching device which can be easily operated by one-touch operation for locking and unlocking.

[0006]

Hereinafter, the description will be made with reference to the reference numerals in the accompanying drawings. In the container lid catching device of the present invention, a receiving hole 11 through which a peg 6 moves in and out of the main body 1 is opened on the rear side. The catch spring 5 is provided on the main body 1 so as to intersect with a part of the receiving hole 11, the catch spring 5 is held in the main body 1 by the cover 2, and the operation lever 3 is attached to the main body 1 by the shafts 3a and 3b. Pivotally attached to the operating lever 3 into the catch spring 5 fitting grooves 3c, 3
d is provided, a tapered portion 6a is provided at the tip of the peg 6, and an annular groove 6b for engaging and disengaging the catch spring 5 is provided on the peripheral surface of the base of the tapered portion 6a.

[0007]

In this lid catching device, the peg 6 is fixed to the container body 8 and the device body 1 is fixed to the container lid 7.
When the lid 7 of the container is closed and rotated, the peg 6 is inserted into the receiving hole 11 of the apparatus body 1 through the insertion opening 2 a of the cover 2. In the process of this insertion, the catch spring 5 is pushed by the tapered portion 6a of the peg 6, so that the catch spring 5 temporarily retracts outside the opening of the receiving hole 11. When the lid of the container is completely closed, the catch spring 5 engages with the annular groove 6b of the peg 6, whereby the lid 7 of the container is locked and locked to the container body 8.

Further, when the lid 7 of the container is released, the operation lever 3 is pulled up. By this operation, the catch spring 5 is pushed back by the inner walls of the fitting grooves 3c and 3d of the lever 3, so that the catch spring 5 escapes from the annular groove 6b of the peg 6. This unlocks the lid 7 of the container from locking the container body 8.

[0009]

In the embodiment shown in FIGS. 1 to 9, the entire apparatus is fixed to the container lid 7 by bolts through fixing bolt holes 2b and 2c. Similarly, the peg 6 is also fixed to the container 8. The catch spring 5 formed in a laterally long ring shape is fixed by inserting both end bent portions into the spring fixing hole 1a of the main body 1. The operating lever 3 has a shaft portion 3
a and 3b are rotatably attached to bearing grooves 1c and 1d on the main body 1 side. The horizontally long straight line portion of the catch spring 5 is fitted into the fitting grooves 3c and 3d of the operation lever 3.

In this embodiment, a reinforcing plate 4 for holding the load from the lever 3 and the catch spring 5 at the time of unlocking is sandwiched between the cover 2 and the main body 1.

Further, in this embodiment, the insertion port 2a of the peg 6 provided on the cover 2 is formed in a tapered shape so that the peg 6 can be smoothly inserted.

Further, in this embodiment, the operating surface 3e of the operating lever 3 is provided with irregularities in order to improve the operability when unlocking.

[0013]

As described above, in the container lid catching device of the present invention, the container lid 7 is closed by the catch spring 5 and the peg 6 which are automatically engaged when the container lid 7 is closed and rotated. 8 is locked and locked while the operating lever 3 is pulled up and rotated to catch the spring 5.
Since the engagement between the and pegs 6 is released, both locking and unlocking can be performed with one touch, and the operation is excellent in convenience.
