Abstract

PURPOSE:To prevent the generation of vibration during transportation by a method wherein a hold rod is provided at its upper part with a head part, and there are provided at its lower part with a check plate brought into contact with the under surface of an engaging metal during release of a vibration isolating device and a contact plate located in a level lower than that of a base bed during compression of the vibration isolating device and releasing the vibration isolating device as a result of the contact plate being pressed when a body is unloaded on a ground. CONSTITUTION:During a time between a point of shipping time and a transportation time, a compressor 15 is firmly fixed. During the fixing period, by striking downward a head part 28 of a hold rod 26 with a proper strength, vibration isolating runner 22 and a spring 23 are compressed in a position where an engaging metal 24 is matched in the middle of a main column part 29 with the diameter of the main column part 29, and the compressor 15 is fixed through legs 19. When the compressor is installed at a site, after it is unpacked, a body 16 is placed on a ground. In this case, since a contact plate 31 is located in a level lower than that of a base bed 18, the contact plate 31 is pushed upward and disengaged from an engaging hole 24 of an engaging metal 25. The contact plate is brought into a free state and released together with the vibration isolating rubber 22 which has been compressed through the force of the spring 23. A check plate 30 is brought into contact with the under surface of the engaging metal 25 and brought into a state in which vibration during operation of the compressor 15 is absorbed.

It is. When the installation is completed on-site, as shown in Figure 5, when the bolts 7 are screwed together and raised upwards, the springs 4 are freed and the vibrations transmitted to the legs 1 (of the compressor) are reduced. It was to be absorbed by spring 4.

Problems to be Solved by the Invention In such a conventional configuration, bolts 7 and 7 are removed during on-site installation.
If you forget to loosen the spring 4, the spring 4 will be operated in a compressed state, and the outdoor unit will not be able to absorb the vibrations generated from the compressor when it is operated, causing damage to the outdoor unit. This caused abnormal vibrations and also caused cracks in the piping connected to the compressor.

The present invention is intended to solve these problems, and it is an object of the present invention to provide a vibration isolating device that prevents vibrations during transportation without requiring work such as loosening bolts on site.

Means for Solving the Problems In order to solve this problem, the present invention provides a vibration isolator which is attached to a plurality of legs provided at the bottom of a compressor and is wrapped with vibration isolating rubber and a spring between it and the bottom plate of the main body. a holding rod having a fitting metal fixed to the lower surface of the bottom plate at a position corresponding to the vibration isolating rubber, and having an inverted conical main column penetrating the vibration isolating device and the fitting metal; The holding rod is provided with a head on the upper part, and a stop plate on the lower part that comes into contact with the lower surface of the fitting metal when the vibration isolator is released, and a stop plate attached to the main body when the vibration isolator is compressed. The structure also includes an abutment plate that is located below and is pushed to release the vibration isolator when the main body is lowered to the ground.

Function: When the air conditioner is shipped to the factory, the head of the holding rod is tapped to fit into the fitting metal midway through the main column, compressing and fixing the vibration isolator, and then shipping it to the factory. During installation, when the main body of the air conditioner is lowered to the ground, the abutment plate located below the base is pushed, and the holding rod is released from the mating metal, thereby removing the vibration isolator. This will absorb vibrations during compressor operation.

Embodiment Hereinafter, an embodiment of a vibration isolating device for a compressor provided in an outdoor unit of an air conditioner according to the present invention will be described with reference to FIGS. 1 to 3. As shown in FIG. 3, a main body 16 of the outdoor unit with a built-in compressor 15 and a base 18 attached to a bottom plate 17 of the main body 16 are provided on both sides.
