Background
In the installation of the inner and outer air conditioner, before the two are connected, horn mouths at two ends of a connecting pipe are required to be processed in advance, and during the installation, the horn mouths are screwed and connected with a connecting valve or a wire head of an air conditioner host machine through nuts attached to the connecting pipe, and a sealing surface is formed by utilizing the spherical surfaces of the horn mouths and the spherical surfaces of the connecting valve or the wire head of the connecting pipe. Thereby completing the connection sealing of the air conditioner internal and external systems.
However, this connection has the following problems:
1. the connecting pipe needs to be processed and stored in advance. And the processing, transportation, personnel training, equipment investment and management cost are increased.
2. The inner surface of the horn mouth is required to be smooth and free of scratches, otherwise slow leakage is caused, user complaints are easily caused, and the quality public praise of enterprises is seriously damaged.
3. When the nut of the connecting pipe is installed, the nut and the valve or the wire head are easily damaged or leaked due to dislocation. Such problems are more likely to occur, especially when working aloft.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the defects in the prior art and providing an air conditioner internal and external machine connecting pipeline joint device.
The technical scheme adopted by the invention for achieving the purpose is as follows: the utility model provides an indoor and outdoor machine of air conditioner connecting pipe joint device, including connecting the fixed head, the nut, the retaining ring, the clamp block, the spring washer, metal gasket, O type sealing washer, the cylindricality sealing washer, connect the middle part of fixed head and nut all to be equipped with the through hole for pass the pipeline of connecting the indoor and outdoor machine of air conditioner, wherein the inside of connecting the fixed head is equipped with the shoulder hole, be used for penetrating the pipeline of connecting the indoor and outdoor machine of air conditioner, the cylindricality sealing washer is installed in the bottom of shoulder hole, the head top of male pipeline is on the cylindricality sealing washer, the cover is outside metal gasket in proper order at male pipeline, the O type sealing washer, the spring washer, clamp block and retaining ring, and be located the shoulder hole of connecting the fixed head, the nut is worn on the pipeline of inserting the fixed head of joint, and screw thread through connecting the fixed head side is screwed up, with clamp block, the metal gasket, the spring washer, O type sealing washer and cylindricality sealing washer compress tightly in the inside of connecting the fixed head.
Further, the clamping block comprises a head part in a round table shape and a cylindrical tail part integrally formed at the tail end of the head part, and a through hole for penetrating through a pipeline for connecting the indoor unit and the outdoor unit of the air conditioner is formed in the middle of the clamping block.
Further, the inner side surface of the head opening of the joint fixing head is a conical surface and is matched with the side surface of the clamping block.
Further, the clamping block is formed by combining two symmetrical clamping members.
The invention changes the design of the air conditioner pipeline connector, increases the sealing and the locking part of the connecting pipe, and the connecting pipe only needs to be installed on site cleanly and directly and quickly, and has the following advantages:
1. the on-site installation efficiency is improved, and the connecting pipe is only required to be inserted into the valve port or the wire head to be pinched
2. The machine connecting pipe is not required to be processed in factories, and the cost of labor, materials, storage and management is saved
3. The leakage quality problem caused by installation operation is effectively reduced, the quality loss is reduced, and the enterprise quality level is improved.
4. The pipe joint can be directly replaced with an inlet pipe joint of an existing air conditioner indoor unit; the novel three-way valve and the novel stop valve can be designed with the existing three-way valve and the stop valve of the existing outdoor unit.
