Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a lid fitting structure for a container body mainly made of synthetic resin, and particularly relates to a lid fitting structure that has been widely used in recent years. It has built-in circuits and mechanisms for small electronic products such as portable head-on stereos, FM radio wave modulation transmitters used with these head-on stereos, and pocket radios, making it possible to remove the lid even in tight spaces. In addition to making it easy to replace batteries and take in and out accessories such as antennas and connection cords without having to
The present invention relates to a lid fitting structure that can provide an opening of an appropriate size depending on the frequency of taking out stored items and is suitable for application to a thin container body.

[Conventional technology]

In the case of containers that incorporate and store the aforementioned equipment, the lid and container are fixed with fixing devices such as screws, so it is not only time consuming to remove and fix them, but also time-consuming. When the lid was opened, the circuit mechanism was exposed to the outside, so there was a high risk of failure due to touching this part.

In addition, there are only a limited number of items stored in this type of container that are often taken out by opening the lid.For example, connection cords are taken out frequently, batteries, etc. are taken out less frequently than connection cords, and even circuits. There is no need to expose the mechanical parts to the outside except for troubleshooting.

However, in the case of the conventional joint structure of the container body and the lid, when the lid is opened, the whole thing is opened as mentioned above, which not only takes time and effort when closing the lid, but also exposes it to the outside as mentioned above. Even circuit parts, etc., which must be extremely protected from being touched, will be opened.

[Problem that the invention attempts to solve]

With this invention, the lid can be smoothly inserted into the container body without the need for fixing devices such as screws or accessories such as springs or bearings, and the number of lids can be adjusted depending on the frequency of stored items that need to be taken out. It slides in stages and can freely change the opening diameter, and is designed to never open the storage area for circuit components that are exposed to the outside and must be protected from being touched. It is an object of the present invention to provide a structure for fitting a lid part of a container body.

[Means to solve the problem]

The above-mentioned problem can be solved by providing an engaging projection on the outside of the sliding race on the outer periphery of the facing side plates of the container body made of synthetic resin, and by cutting out one side. A plurality of engagement recesses that engage with the engagement protrusions are formed at regular intervals in the inner circumferential groove of the lid side plate made of a synthetic resin material that is slidable in any direction. The recess near the body side plate notch becomes an engagement recess for a stopper that cannot slide in the direction of the opposite side plate notch of the lid body after the engagement protrusion is inserted, and the other engagement recesses are combined with each other. The problem is solved by a structure for fitting the lid of a container body, which utilizes the elasticity of the resin material and forms a tapered part so that the engaging convex part can be freely removed.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

Figure 1 shows a container body made of synthetic resin material.
Starting from one direction, connection cord 2 that also serves as an antenna,
A battery 3 and a circuit mechanism 4 are housed therein. 5
are sliding rails formed on opposite side plates of the container body 1, and the sliding rails have engaging convex portions 6.
is installed protrudingly. 7 is a lid made of synthetic resin material, with a notch 8 cut out on one side plate;
A groove 9 for engaging and sliding with the sliding rail of the container body is formed on the inner periphery of both opposing side plates, and the groove 9 has three engaging recesses 10a, 10b at regular intervals. , 10c are formed.
In the case of the engagement recess 10a in the direction of the notch side plate, the notch face in the direction of the notch side plate is cut out vertically, and when the engagement convex portion 6 of the container body 1 is fitted into the engagement recess 10a, Sliding in the direction of the notched side plate is completely prevented. Also, the notch surface of the engagement recess 10a in the direction opposite to the notch side plate and the engagement recess 1 in the direction opposite to the notch side plate.
Tapered portions are formed on the cutout surfaces of 0b and 10c. Therefore, even if the engaging protrusion 6 of the container body 1 is once inserted into the engaging recesses 10b and 10c and stopped, it can easily slide due to the elasticity of the synthetic resin material and the assistance of the tapered part. can do.

In the above structure, when the container body 1 and the lid part 7 are completely fitted together, the engaging protrusion 6 is fitted into the engaging recess 10c having a tapered part, as shown in FIG. Next, when you want to remove the frequently used connection cord 2, as shown in FIG.
By sliding the engaging convex portion 6, the engaging convex portion 6 fits into the engaging concave portion 10b having a tapered portion. When the connection cord 2 is taken out, the lid body 7 is slid in the opposite direction to be in the completely closed state shown in FIG. 5.

When replacing the battery, if the lid 7 is further slid as shown in FIG. 3, the engaging convex portion 6 will fit into the aforementioned engaging recess 10a, and the connecting cord 2 and battery will be replaced as shown in FIG. 3 will be exposed to the outside. However, as described above, since the lid 7 cannot slide in the direction opposite to the notch side plate, the circuit mechanism 4 is not exposed to the outside. After replacing the battery, connect the connection cord 2.
By sliding in the direction of the storage section, the state shown in FIG. 4 can be easily changed to the completely closed state shown in FIG. 5. Moreover, the engaging recesses 10a, 10
The connection cord storage portion 2 and the battery 3 are positioned in advance at the formation locations b and 10c so as to be exposed in stages.

Further, the two engaging protrusions 6 may have the same shape, but as shown in this embodiment, one may be a rectangular large-diameter protrusion and the other may be a small-diameter triangular piece to achieve the same effect. Can be done.

〔effect〕

Therefore, according to the present invention, it is possible to smoothly and reliably fit the lid to the container body without using fixing devices such as screws, and the present invention is particularly suitable for items that are frequently taken out. The opening diameter can be changed in stages according to the requirements, and it is preferable to prevent the external exposure of the circuit mechanism, etc. Since the storage area of the parts is never opened, it is possible to prevent connection cords, batteries, circuit mechanisms, etc. FM with built-in
For radio wave modulation transmitters, if you store the connection cord and battery in the order of removal frequency from the opening base, and place the circuit mechanism in the part that cannot be opened, FM radio wave modulation with excellent functionality and safety can be achieved. You can get a transmitter.
