Description

[Detailed Description of the Invention] [Detailed Description of the Invention] The present invention relates to a vibration isolating support device, and particularly to a vibration isolating support device suitable for vibration isolating and supporting a hermetic electric compressor.

The present applicant has already proposed the anti-vibration support device shown in FIGS. 1 and 2. In Figures 1 and 2,
Reference numeral 1 denotes a hermetic housing of a hermetic electric compressor, which has a discharge pipe 2 at its top and a suction pipe 3 at its outer periphery.
Reference numeral 11 denotes a vibration isolating member integrally molded from an elastic material such as rubber and having a bottomed cylindrical shape with an open upper end, which contacts and surrounds the outer periphery and bottom surface of the housing 1. The bottom flange 16 of this vibration isolating member 11 is connected to the bolt 7
It is assembled into the air conditioner by fastening it to the bottom plate 10 of the air conditioner with washers 8 and nuts 9, and connecting the discharge pipe 2 and suction pipe 3 of the housing 1 to the refrigerant pipes 4 and 5 of the air conditioner, respectively. .

A slit 6 of a predetermined length is provided on the outer periphery of the vibration isolating member 11 from its upper open end along its generatrix, and while the suction pipe 3 is moved along the slit 6, the housing 1 is moved above the vibration isolating member 11. The band 12 is inserted into the housing from the open end, and then the band 12 is stretched over the upper open end of the vibration isolating member 11.
This prevents the slit 6 from popping out upward and also prevents the slit 6 from expanding.

In the above equipment, when transporting the air conditioner,
Since the band 12 bends when the housing 1 is subjected to a force in a direction that causes it to pop upward, it cannot reliably block this force, and therefore an abnormally large force is applied to the refrigerant pipes 4 and 5, deforming or damaging them. There was a problem with cracks forming. Furthermore, since the housing rotates relatively within the vibration isolating member 11 when receiving vibrational forces when the compressor starts and stops, there is also a risk of cracks or deformation occurring in the refrigerant pipes 4 and 5. It was hot.

The present invention was proposed in order to deal with the above problem, and its gist is that the vibration isolating member is integrally molded from an elastic material such as rubber and has a bottomed cylindrical shape with an open upper end. The cylindrical housing is in contact with and surrounds the outer periphery and bottom surface of the cylindrical housing in which a vibration source such as a machine is housed, and a protrusion protruding from the outer periphery of the housing is accommodated in the cylindrical portion of the vibration isolating member and engaged with the cylindrical housing. The present invention provides a vibration isolating support device characterized in that a stopper groove consisting of a vertical groove and a horizontal groove is provided.

Since the present invention has the above configuration,
The protrusion protruding from the outer periphery of the housing is engaged with the stopper groove provided on the outer periphery of the vibration isolating member to restrain relative movement between the housing and the vibration isolating member, and the external force applied to the housing is absorbed by the elastic material. Since it can be absorbed by the vibrating member, it does not cause deformation or cracks in the refrigerant piping unlike in the past, and the conventional band is no longer necessary, making it possible to reduce the cost of parts and installation. .

Hereinafter, the present invention will be explained in detail with reference to an embodiment shown in FIGS. 3 and 4.

Reference numeral 14 denotes a vibration isolating member made of an elastic material such as rubber and having a cylindrical shape with an open bottom and which contacts and surrounds the outer periphery and bottom surface of the housing 1. Reference numeral 15 denotes a stopper groove provided on the outer periphery of the vibration isolating member 14 to lock the suction pipe 3 protruding from the outer periphery of the housing 1, and as shown in FIG. After extending for a predetermined length along the line, bending laterally, and then folding back slightly upward, the overall shape is J.
It is shaped like a letter. The rest of the structure is the same as the conventional one shown in FIGS. 1 and 2, and corresponding members are given the same reference numerals.

The housing 1 connects the suction pipe 3 to the stopper groove 1.
5, the vibration isolating member 14 is inserted into the housing 1 from the upper open end thereof, and at the end of the stroke, the housing 1 is pushed down strongly, the vibration isolating member 14 made of an elastic material is deformed, and the suction The tube 3 is engaged with the upper folded portion of the stopper groove 15, and its upper and both sides are restrained from moving by the stopper groove 15, and its lower part is restrained from movement by the elasticity of the vibration isolating member 14.

Thus, when transporting the air conditioner, the housing 1
The shock applied to the compressor and the excitation force acting on the housing when starting or stopping the compressor are absorbed by the vibration isolating member 14 made of an elastic material through the suction pipe 3 and the stopper groove 15.
Since the vibration is transmitted to the vibration isolating member 14 and absorbed by the vibration isolating member 14, cracks and deformation do not occur in the refrigerant pipes 4 and 5 as in the conventional case. Furthermore, since the conventional band can be abolished, the cost of parts and installation can be reduced, contributing to cost reduction.

Although an example in which the present invention is applied to a hermetic electric compressor has been described, it goes without saying that the present invention can be widely applied to vibration-proof support of a cylindrical vibrating body having projections on its outer periphery.
