Description

Technical Field

[0001] The utility model relates to the technical field of heat preservation of air-conditioning pipelines, in particular to a low-temperature antifreeze air-conditioning pipeline. Background Art

[0002] Air conditioning duct refers to the air conditioning copper pipe, which is an indispensable and important part of the air conditioning system. It undertakes the important task of connecting the indoor unit and the outdoor unit. However, in order to ensure the stability of the temperature change inside the copper pipe during the operation of the air conditioning system, thereby improving the operating efficiency of the air conditioning, a layer of thermal insulation cotton will be added to the outside of the copper pipe. Especially in cold weather, it can provide insulation for the copper pipe and prevent the dripping of condensed water, thereby ensuring a dry indoor environment.

[0003] However, the existing air-conditioning copper tubes are only covered with a layer of thermal insulation cotton for thermal insulation control. The structure is relatively simple and the thermal insulation effect needs to be improved. At the same time, the air-conditioning copper tubes located on the outside are at risk of being damaged by external objects, and the single thermal insulation cotton can only play a small protective role, and its protective function needs to be strengthened. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical defects and provide a low-temperature antifreeze air-conditioning pipeline, which can enhance the thermal insulation effect and improve its protection function, thereby extending the service life of the air-conditioning copper pipe.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is: a low-temperature antifreeze air-conditioning duct, comprising an air-conditioning copper tube body, the two ends of the air-conditioning copper tube body are bell-mouth structures, the outside of the bell-mouth is sleeved with connecting nuts, the outside of the air-conditioning copper tube body is sleeved with a protective sleeve, and several groups of supporting mechanisms are arranged between the protective sleeve and the air-conditioning copper tube body. The outside of the protective sleeve is sleeved with thermal insulation cotton, and both ends of the air-conditioning copper tube body are threadedly connected with limit end covers for fixing the two ends of the thermal insulation cotton.

[0006] As an improvement, the support mechanism is three support plates evenly distributed on the outer wall of the air conditioner copper tube body.

[0007] As an improvement, the support plate and the protective sleeve are both made of rubber material, the support plate and the protective sleeve are an integrally formed structure, and one end of the support plate and the air conditioner copper tube body are adhesively connected.

[0008] As an improvement, the two ends of the thermal insulation cotton extend to the outside of the two ends of the protective sleeve respectively, and are pressed and fixed between the end of the protective sleeve and the limiting end cover through the limiting end cover.

[0009] As an improvement, one end of the protective sleeve is provided with a drainage pipe extending to the outside of the thermal insulation cotton.

[0010] As an improvement, a plurality of anti-slip grooves are evenly arranged on the outer wall of the position-limiting end cover.

[0011] Compared with the prior art, the utility model has the following advantages: the outer side of the air-conditioning copper tube is first connected to the protective sleeve through a plurality of groups of supporting mechanisms, and the thermal insulation cotton is sleeved on the outside of the protective sleeve. The double-layer design of the protective sleeve and the thermal insulation cotton can improve the thermal insulation effect. At the same time, the protective sleeve can improve the protection of the air-conditioning copper tube, thereby improving the anti-collision ability and extending its service life.

[0016] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] As the instruction manual Figure 1 , 3 As shown, a low-temperature antifreeze air-conditioning pipeline comprises an air-conditioning copper tube body 1, both ends of the air-conditioning copper tube body 1 are bell-mouth 4 structures, and the bell-mouth 4 is sleeved with a connecting nut 2 on the outside. The structure of the air-conditioning copper tube body 1 is the same as that of the existing ones, and in addition, external threads are provided on one side of the bell-mouths 4 at both ends thereof for connecting the limit end caps 3 mentioned below, and the connecting nuts 2 at both ends of the copper tube are connected and fixed to the indoor unit and the outdoor unit of the air-conditioning;

[0018] As the instruction manual Figure 2 As shown, the outer sleeve of the air-conditioning copper tube body 1 is provided with a protective sleeve 7, and a plurality of supporting mechanisms are provided between the protective sleeve 7 and the air-conditioning copper tube body 1. The supporting mechanisms are three supporting plates 6 evenly distributed on the outer wall of the air-conditioning copper tube body 1. The supporting plates 6 and the protective sleeve 7 are both made of rubber material. The setting of the rubber material has certain elasticity and toughness, and does not affect the bending of the air-conditioning copper tube 1 during installation. The supporting plate 6 and the protective sleeve 7 are an integrated structure, and one end of the supporting plate 6 and the air-conditioning copper tube body 1 are connected by adhesive;

[0019] As the instruction manual Figure 3As shown, the outer part of the protective sleeve 7 is sleeved with thermal insulation cotton 5, and both ends of the air-conditioning copper tube body 1 are threadedly connected with limit end covers 3 for fixing the two ends of the thermal insulation cotton 5, and the outer wall of the limit end cover 3 is evenly provided with a plurality of anti-slip grooves 8, and the setting of the anti-slip grooves 8 facilitates the twisting of the limit end cover 3, and the two ends of the thermal insulation cotton 5 extend to the outside of the two ends of the protective sleeve 7 respectively, and are pressed and fixed between the end of the protective sleeve 7 and the limit end cover 3 by the limit end cover 3. One end of the protective sleeve 7 is provided with a drain pipe 9 extending to the outside of the thermal insulation cotton 5, and the drain pipe 9 can discharge the condensed water generated by the air-conditioning copper tube body 1.

[0020] In the specific implementation of the utility model, one end of the pipe body provided with a drain pipe is connected to the outdoor unit of the air conditioner, and the other end is connected to the indoor unit of the air conditioner. The installation height of the outdoor unit is lower than that of the indoor unit, so that condensed water can be discharged to the outside. The connection method at both ends of the air conditioner copper tube body is the same as the existing air conditioner copper tube connection method. The air-conditioning duct of the present application adds a layer of rubber protective cover between the air-conditioning copper tube body and the thermal insulation cotton. At the same time, under the connection support of multiple support plates, a certain distance is left between the protective cover and the air-conditioning copper tube body, thereby providing a certain buffer space. When impacted by external force, the impact force can be greatly buffered, thereby improving its protective performance. At the same time, the double-layer design of the protective cover and the thermal insulation cotton can improve its thermal insulation effect.

[0021] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
