Abstract

PURPOSE:To improve assembly property by providing grooves on both sides of an elastic body supporting a supporting body, and sliding a bracket provided with two planes having projecting parts fitted to the grooves. CONSTITUTION:A supporting tool is composed of a bracket 3 and a vibrationproof rubber (elastic body) 4. On the opposing two planes 3a of the bracket 3, projecting parts 3b with the slitting bent are oppositely provided. The vibrationproof rubber 4 is provided with fitting parts 4a to the two planes 3a of the bracket 3 and a leg part 4b. The fitting parts 4a are formed with groove parts 4c to receive the projecting parts 3b. A supported body is fixed on the bracket 3 and held. As the vibrationproof rubber 4 is slidingly fitted and held to the bracket, assembly property is improved without use of subsidiary plates or screws.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a support for supporting a supported object.

[Prior art] For example, when installing a heat exchanger such as a refrigerant condenser or refrigerant evaporator used in a vehicle refrigeration cycle to the vehicle body, the brackets attached to the heat exchanger are attached to the brackets that serve as the legs of the heat exchanger. Anti-vibration rubber is installed.

This anti-vibration rubber is fixed to an auxiliary plate fixed to the bracket with screws, rivets, etc. Alternatively, as shown in FIG. 5, the auxiliary plate 1 fixed to the bracket 100
Attach another auxiliary plate 102 to 01 by welding or the like,
The end of this auxiliary plate 102 is fixed by engaging the inner periphery of the vibration isolating rubber 103.

[Section VI1 that the invention aims to solve] However, the above-mentioned conventional technology requires a tightening process using screws or rivets, or a process for assembling auxiliary plates, so it is difficult to assemble, and as the number of parts increases, it becomes difficult to assemble. The problem was that the manufacturing cost was high.

The present invention was made based on the problem of Dojo, and its purpose is to facilitate assembly and reduce the number of parts! 3! An object of the present invention is to provide a support for a supported body that can reduce manufacturing costs.

[Means for Solving the Problems 1] In order to achieve the above object, the present invention comprises a bracket fixed to a supported body, and an elastic body held by the bracket to support the supported body; The bracket is
While looking at the two opposite sides of the elastic body,
The two surfaces are provided with opposing protrusions, and the elastic body is provided with grooves on both side surfaces that fit into the protrusions, and is slid between the two surfaces of the bracket 8. The technical means is that the projecting portion and the arm portion are fitted together to be held by the bracket.

[Operations and Effects of the Invention 1] The present invention having the above-mentioned configuration has the following features:
Part 3 allows the bracket to hold the elastic body.

Therefore, unlike conventional methods, there is no need for the tightening process with screws or rivets, or the process of assembling auxiliary plates, making it possible to improve ease of assembly and reduce the number of parts. can be lowered.

[Example] Next, a supporting device for a supported body according to the present invention will be described based on an example, which is not shown in the drawings.

FIG. 1 is a perspective view of the bracket and the vibration rubber, and FIG. 3 is a view of the support when it is attached to the heat exchanger.

As shown in FIG. 3, the support 1 of this embodiment is a heat exchanger (supported body of the present invention) 2 used in a vehicular refrigeration cycle.
A bracket }.3 that supports the heat exchanger 2 and is fixed to the bottom of the heat exchanger 2, and a vibration isolating rubber (elastic body of the present invention) that is held by the brackets 1 and 3 and absorbs vibrations from the vehicle body. It consists of 4.

The heat exchanger 2 is, for example, a refrigerant condenser or a refrigerant evaporator, and has headers 2c and 2d disposed on both sides of a core section made up of tubes 2a and fins 2b.

The bracket 3 is formed into a U-shape in cross section, and the bottom part is 1
, are arranged along the entire length of the core portion.

Both ends of this bracket 3 are brazed to the side surfaces of the headers 2c and 2d, and the lowermost fin 21) is brazed to the outer surface of the bottom surface.

Opposing both side walls of brackets 1 and 3 (two sides of the present invention) 3a
As shown in FIG. F, a protruding portion 3b is formed by bending a rectangular cut portion inward.

The protrusions g3b are provided near both ends of the bracket 3 (four locations in total) and are shaped to face each other on both side walls 3a.

The vibration isolating rubber 4 is disposed at both ends of the bracket 3 to support the heat exchanger 2.

This anti-vibration rubber 4 has a fitting part 4a that is fitted into the bracket 3 along the opposite side walls 3a of the bracket l-3, and a leg part 11 formed at the bottom of this fitting part 4a (7). 4b.

The fitting portion 4a has slit-shaped groove portions 4C formed on both side faces facing the side walls 3a of the bracket 3, which fit into the protruding portions 31 of the brackets I to 3.

This groove portion 4C is formed in a rectangular shape from one end surface (left side in FIG. 1) of the fitting portion 4a toward the other end surface and from both side surfaces toward the inside, and accommodates the entire protruding portion 3b. It is set in a size that allows for.

Note that when the anti-vibration rubber 4 is held on the bracket 3,
The leg portions 4b protrude downward from both side walls 3a of the bracket 3, as shown in FIG.

When making the bracket 3 hold the anti-vibration rubber 4, the fitting parts 4a of the anti-vibration rubber 4 are fitted into the bracket 3 along both side walls 3a of the bracket 3, and The groove portion 4C formed in the fitting portion 4a is fitted into the protruding portion 3b while sliding it.

As shown in FIG. 4, a protrusion 3C is formed on the lower surface of the protrusion 3b, and a recess 4d is formed on the inner surface of the groove 4C, so that when the groove 4C is fitted into the protrusion 3b, The anti-vibration rubber 4 may be prevented from falling off by fitting the convex portion 3C and the concave portion 4d.

As described above, in this embodiment, the vibration isolating rubber 4 is held by fitting the protruding portion 3b provided on the bracket 3 and the corner portion 4C formed on the vibration isolating rubber 4. Therefore, unlike conventional methods, there is no need for the process of assembling auxiliary plates or tightening with screws or rivets.
The ease of assembling the support 1 can be improved. Furthermore, the number of parts can be reduced and manufacturing costs can be lowered.

In this embodiment, the support 1 consisting of the bracket 3 and the anti-vibration barrier 4 was explained as supporting the heat exchanger 2 of the refrigeration cycle, but the supported object is the heat exchanger 2.
It is not limited to.
