Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an improvement of the insulated fishing box of the invention.

Conventional technology In 1977, it was discovered that in a cold storage box for fishing, fish, etc. can be taken in and out by opening and closing a small lid that fits into a charging hole formed in the lid plate without opening or closing the lid plate of the box body.
This is known from Publication No. 87297, but the opening and closing operations are extremely complicated because the small lid must be rotated to release the engagement with the lid plate and then opened upward. There is also a defect with large dissipation.

It is also known to open and close the small lid with a single touch, as seen in Japanese Utility Model Application Publication No. 54-73291, but this method uses a spring to force the small lid into the open state and an operating lever provided on the lid plate. Because the lid is pressed down, the injection hole opens fully every time the lid is opened, causing a large amount of cold air to dissipate, reducing the cold insulation effect.

Problems to be Solved by the Invention In view of these current circumstances, the present invention aims to simplify the operation of opening the lid by gripping the small lid and making it possible to open the lid with a single touch and by freely adjusting the opening/closing degree. It is also an object of this invention to prevent a decrease in the cold insulation effect due to the dissipation of cold air.

Means for Solving the Problems The present invention has a structure for achieving the above-mentioned object, in which a small lid, one side of which is pivoted, is fitted into an input hole drilled in the lid plate of the cold box body so that it can be opened and closed upwards. A locking plate is slidably provided on the open end side of the small lid, the locking plate is biased by a spring so that its tip engages with a locking groove provided in the input hole, and has a fitting recess on the upper surface. The gist is that an operating piece having a rotating piece is pivoted to the small lid above the locking plate so as to be able to rise and fall freely, and the tip of the rotating piece is engaged with a fitting recess of the locking plate. be.

Embodiment An embodiment of the present invention will be described with reference to the drawings.
A charging hole 3 is bored in the charging hole 3, and a small lid 6 having one end supported by a shaft 4 and having a recessed part 5 formed in the upper part is fitted in the charging hole 3 so as to be openable and closable. 3
An inclined guide wall 3' is formed on the inner wall surface on the open end side of the small lid.

An operating piece 7 is provided on the open end side of the concave portion 5 of the small lid 6.
is rotatably supported by protruding shafts 8, 8 integrally provided thereon, and a rotating piece 9 is integrally fixed to each of the protruding shafts 8.

Further, on the bottom surface of the small lid 6 below the operation piece 7, a locking plate whose tip can freely come out and retract from a long hole 10 formed in the small lid 6 and is biased so as to protrude from the long hole 10 by a spring 11 is provided. 12 is slidably provided, and a locking groove 13 for engaging the locking plate 12 is formed in the cover plate 2, and furthermore, on both sides of the locking plate 12, the tip of the rotating piece 9 is provided. A fitting recess 14 is provided in which the fitting recess 14 is engaged.

Since the embodiment of the present invention is constructed as described above, when opening the small lid 6, when the end edge of the operation piece 7 is rotated and pulled upward with a finger, the tip ends in the fitting recess 1.
The rotating piece 9 engaged with the locking plate 4 slides inward on the locking plate 12 and disengages from the locking groove 13 of the cover plate 2, so the small cover 6 is rotated upward. can do. Further, when closing the small lid 6, when the small lid 6 is rotated and pressed downward, the tip of the protruding locking plate 12 is moved by the inclined guide wall 3' of the insertion hole 3 of the small lid 6 to the spring 11. When the small lid 6 is guided and pressed inward against the biasing force and fitted into the charging hole 3, the locking groove 13 is closed.
It is something that engages with.

Effects of the invention The present invention allows the locking plate to be detached from the locking groove by pulling the small cover of the operation piece in the opening direction, and then continues to rotate the small cover upward in a one-touch operation. While the lid can be opened and closed, simply press and rotate the small lid, and the locking plate automatically engages with the locking groove, so opening and closing the small lid can be done with a single touch. This is easy to do, and the small lid is pivoted to open and close, and the degree of opening and closing can be adjusted freely by the hand opening and closing, so cold air can be dissipated by opening and closing the minimum degree according to the size of the fish, etc. to be stored. It has excellent features and practicality that prevents cold storage and does not reduce the cold insulation effect.
