Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for attaching resin parts to the surface of a metal exterior body of a magic bottle, rice cooker, or the like.

Conventionally, methods for attaching resin parts to the surface of a metal exterior body include screwing screws into the resin part from the back side of the exterior body, or creating screw insertion holes in the resin part and inserting nuts on the back side of the exterior body. There was a method of tightening and fixing the resin parts using screws and nuts.

However, in the former case, the plastic part needs to be thick enough to allow the screw to be screwed into it, which not only makes it impossible to install with a thin plastic part, but also requires screwing from the back side of the exterior body, which reduces workability. It was bad and had the disadvantage that the screws came loose.
In addition, in the latter case, two parts, a screw and a nut, are required to attach the resin part, which increases the number of parts and, like the former, there is a concern that the screws may come loose.

The present invention has been developed in view of these conventional problems, and it allows resin parts to be easily attached to the exterior body without using screws or nuts, does not impose restrictions on the thickness of the resin parts, and does not loosen after installation. The purpose of the present invention is to provide a structure for attaching resin parts to a metal exterior body without any metal parts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

FIG. 1 shows a magic bottle which is an example of the present invention, in which 1 is a metal exterior body of the magic bottle, 2 is a shoulder body fixed to the upper end of the exterior body 1, and 3 is a shoulder body 2.
a lid body 5 which is pivotally connected to the upper part of the body via a hinge part 4 so as to be freely openable and closable, and has an air pump (not shown) built therein;
is a medium bottle housed inside the exterior body 1. A rectangular through hole 1a is formed in the front surface of the exterior body 1.

6 is a tube cover detachably attached to the front part of the exterior body 1, 7 is a pouring connection tube attached from the lower end opening of the tube cover 6, and the upper end of this pouring connection tube 7 is attached to the middle bottle 5. It opens below the spout 8a of the spout pipe 8 that communicates with the inside. Further, the upper end of the tube cover 6 is locked to the lower surface of the beak-shaped tip of the shoulder body 2.

Reference numeral 9 denotes a receiver which is an example of a resin component according to the present invention. It prevents the tube cover 6 from separating from the exterior body 1 and supports the lower end of the tube cover 6. The receiver 9 includes a back member 10 and a front member 15 made of synthetic resin.
As shown in FIGS. 2 to 4, the back member 10 has a rectangular platform 11 projecting from one side thereof, and a claw portion 12 (an engaging portion) at the upper end of the front surface of the platform 11. ) are provided, and guide grooves 13 (guide portions) are formed on both side surfaces of the base portion 11. Further, a large flange portion 14 is protruded from the base surface of the platform portion 11,
This collar portion 14 can come into contact with the back surface of the peripheral edge of the through hole 1a of the exterior body 1. On the other hand, the front surface of the front member 15 is provided with a square-shaped protrusion 16 that locks the lower end locking portion 6a of the tube cover 6, and the rear surface is provided with an opening 17 that is open on the lower and rear sides. , guide ribs 1 slidably engage with the guide grooves 13 of the back member 10 on both side edges of the opening 17.
8 (guide portion) is formed. Note that the guide rib 18 gradually becomes thicker from the bottom to the top (bottom thickness, top thickness L), and its guide surface is inclined. Further, a recess 19 (engaging portion) is formed at the upper end of the opening 17, and the claw portion 12 of the back member 10 fits into this recess 19 at the slide end position to prevent sliding. It's summery.

Next, a method for attaching the receiver 9 having the above structure to the exterior body 1 will be explained.

First, the base part 11 of the back member 10 is fitted into the through hole 1a of the exterior body 1 from the back side, and the front member 15 is slid from above onto the base part 11 protruding from the front side of the exterior body 1. 15 guide ribs 1
8 is slidably engaged with the guide groove 13 of the base part 11, and at the sliding end position, the upper surface of the base part 11 comes into contact with the upper surface of the opening 17, and the claw part 12
fits into the recess 19, and sliding in both the up and down directions is prevented. In particular, since the guide ribs 18 gradually become thicker from the bottom to the top, the inner surface of the front member 15 presses against the surface of the exterior body 1 as it slides. As described above, the back member 10 and the front member 1
5, the periphery of the through hole 1a of the exterior body 1 is clamped between the flange 14 of the back member 10 and the inner surface of the front member 15, and the receiver 9 is attached to the exterior body 1. It is securely fixed.

In the above embodiment, since the inner surface of the front member 15 and the side surface of the flange 14 of the back member 10 are arcuate surfaces in accordance with the curvature of the exterior body 1, the front member 15 and the back member 1
0 is attached to the exterior body 1, the attachment stability is good. Further, as the guide portions between the front member 15 and the back member 10, contrary to the embodiment, a guide groove may be provided on the front member 15, and a guide rib may be provided on the back member 10, respectively. Furthermore, the same applies to the engaging portions, and the front member 15 may be provided with a claw portion and the back member 10 may be provided with a recessed portion.

In the above embodiment, the front member 15 is attached to the back member 10 by sliding it from above, but the present invention is not limited thereto, and the front member 15 may be attached to the back member 10 by sliding it from the side or from below. If the resin part is a receiver 9 that receives the load of the mounted part (pipe cover 6), it is better to slide the front member 15 against the back member 10 from above so that the load of the mounted part is transferred in the sliding direction. Since the sliding engagement does not come off, the installation is more secure. In addition to the pipe cover 6, the parts to be attached to the holder 9, which is an example of the resin part, may be a tea strainer, or in the case of a rice cooker, etc., a rice cooker holder. In addition to the above-mentioned receivers, the resin parts according to the present invention may also be parts that do not bear any load, such as name plates and display boards.

As is clear from the above explanation, according to the present invention, the base part of the back member is fitted into the through hole of the exterior body and can be moved up and down.
They are positioned on the left and right and protrude to the front side, and the front member is slid onto the protruding parts to clamp the exterior body to the front and back members, and the engaging part of the front member is engaged with the engaging part formed on the base part. By aligning them, the slide was prevented from coming off. Therefore, resin parts can be attached to the exterior body extremely easily without using any screws or nuts, and they will not loosen or come off even when subjected to vibration or impact, and even thin-walled resin parts can be attached to the exterior body. Can be installed.
