Description

[Detailed Description of the Invention] The present invention relates to an opening/closing lid for an automobile lid lock that closes the lock head of the gasoline tank lid exposed to the outside of the vehicle. Conventionally, locks installed on the outer panel or lid of a car leave the key insertion slot open, as shown in, for example, Japanese Utility Model Application Publication No. 55-73470. This has the disadvantage that the parts inside the lock get corroded by rust.To solve this problem, a shutter that can be opened and closed is installed on the head of the lock, and this shutter prevents water from entering. It is prevented. However, since this shutter is attached to the lock head so that it rotates inward when the key is inserted, water on the shutter may seep into the lock when the key is inserted, or the shutter spring may be weak, causing problems when washing the car. The water pressure causes the shutter to open slightly, allowing water to enter through the gap. Water that has entered in this way can freeze inside the lock in cold weather, making it difficult to insert the key, and parts inside the lock may be destroyed when the key is forcefully inserted. .

The object of the present invention is to overcome the above-mentioned drawbacks by providing an opening/closing lid on the head of the conventional lock without or with a shutter, which can be opened and closed by hand and completely prevents water from entering.

An embodiment of the present invention will be described below with reference to the drawings. In the present invention, a lid body 2 and a ring body 4, which are provided on the head of a lock body 1 so as to be openable and closable, are connected by a hinge part A. , molded from synthetic resin.

A finger hook 3 is formed on the lid 2, and an outer wall 2c is formed on the outer peripheral edge 2a of the back surface of the lid 2. A circular inner wall 2d that fits into the head 1a of the lock body 1 is formed inside the outer wall 2c surrounding the ring, and an engaging portion 2e is formed on the outer peripheral edge of the circular inner wall 2d. Ru. This lid body 2 is formed with a bearing part 6 into which a shaft part 5 integrally molded to the ring body 4 is fitted to form the hinge part A, and also serves to prevent the lid panel from being scratched. An engaging portion 4 is formed on the inner peripheral wall edge of the circular wall portion 4'' of the ring body 4, which has a hole into which the lock body 1 is fitted and notches 4a to 4d, and four engagement portions are formed on the wall surface 4' of the ring body 4. The notches 4a, 4b, 4c, and 4d are formed. Projections 1c and 1d formed on the outer peripheral wall surface 1b of the lock body 1 are fitted into these notches 4a and 4b, and the rotation of the lid body 2 is performed. movement is prevented.

Engagement portions 2e and 4 formed on the lid body 2 and the ring body 4
It is molded with resin so that it is engaged when the lid body 2 is closed and will not come off due to vibrations or shocks from the car, but can be easily removed by hooking your finger on the finger hook 3 and pulling it. .

Further, FIG. 3 shows another embodiment of the hinge part A, in which the lid body 2 and the ring body 4 are integrally molded with resin, and the hinge part A has a notch groove 7 formed therein and folds at this thin part. I can sing.

As described above, in the present invention, engaging parts are formed on the lid body which is operated by hand to open and close, and the ring body fitted to the lock body, and the lid body is kept in a sealed state by the engagement of these engaging parts. Since the lid is provided with an outer wall portion that holds the lock and surrounds the ring, water does not enter into the lock and freezing of the lock can be sufficiently prevented.
