Description

Technical Field

[0001] This utility model belongs to the field of pipe connection technology, specifically relating to an air conditioning water pipe connection device. Background Technology

[0002] Air conditioning is a device that can artificially regulate the temperature, humidity, airflow speed, and cleanliness of air in a specific space. Its main function is to meet people's comfort needs by adjusting these parameters, while also meeting the special requirements of industrial production processes. For example, water-based HVAC systems refer to air conditioning systems that use water as a medium to transfer heat and cold. It can transport the heat and cold generated by cold and heat sources through a water pipe system to various air conditioning equipment, and ultimately provide this heat and cold to the air-conditioned room.

[0003] When installing an air conditioner, it is necessary to connect two adjacent air conditioner water pipes using flanges or threads. However, after connecting water pipes with flanges or threads, water pressure testing is required to detect leaks and conduct a leak prevention test at the water pipe connection. However, in newly built buildings, leak prevention tests cannot be conducted because water and electricity are not yet connected, which will delay the installation period of the air conditioner. In this regard, this application proposes an air conditioner water pipe connection device. Utility Model Content

[0004] The purpose of this utility model is to provide an air conditioning water pipe connection device to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] An air conditioning water pipe connection device includes a first pipe body and a second pipe body, and a connection mechanism disposed between the first pipe body and the second pipe body. Each of the first pipe body and the second pipe body has an annular protrusion end on one side, and each of the annular protrusion ends of the first pipe body and the second pipe body has a guide slope. A pre-compressed rubber ring is fitted and abutted between the guide slopes of the first pipe body and the second pipe body.

[0007] The connecting mechanism includes a first flange installed on the outer side of one end of the first pipe body, a second flange installed on the outer side of the second pipe body, and a fixing mechanism disposed between the first flange and the second flange. The side wall of the second flange is provided with a plurality of positioning holes, and a plurality of pre-pressurized positioning rods that are fitted into the positioning holes are fixed at the outer edge of the first flange.

[0008] As a further optimization of this utility model, the annular protrusions of the first pipe body and the second pipe body are fitted together and abut against the first flange and the second flange.

[0009] As a further optimization of this utility model, the first flange and the second flange are provided with a plurality of fixing holes, and fixing bolts are movably provided between the fixing holes of the first flange and the second flange.

[0010] As a further optimization of this utility model, the fixing mechanism includes a gasket movably disposed outside the screw end of the fixing bolt and mating against the outer wall of the first flange, and a nut threaded on the outside of the screw end of the fixing bolt for pressing the gasket towards the first flange. The nut end of the fixing bolt mating against the outer wall of the second flange.

[0011] As a further optimization of this utility model, a number of iron protective covers are provided on one side of the first flange to cover the connection between the fixing bolts and nuts.

[0012] As a further optimization of this utility model, a number of annular magnets for magnetically fixing the iron protective cover are fixed on one side of the first flange.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By conducting pre-compression tests on components such as the pre-compression rubber ring in the laboratory, and then fully inserting the pre-compression rod into the positioning hole, the squeezing force of the two adjacent pipes on the pre-compression rubber ring can reach the pressure that will not leak during the test. This allows the pre-compression rubber ring to be installed and used immediately at the installation site of the air conditioning water pipe connection, thus eliminating the need to conduct anti-leakage tests on the water pipe connection at the installation site and ensuring that no leakage occurs at the pipe connection during use.

[0015] 2. By inserting the pre-pressurized positioning rod into the positioning hole, the fixing holes on the first and second flanges can be quickly aligned for positioning. This facilitates the subsequent installation and fixing of the first and second flanges by using fixing bolts and other components through the aligned fixing holes. The iron protective cover can cover the connection between the fixing bolts and nuts, preventing the connection between the fixing bolts and nuts from directly contacting external rainwater and easily corroding. The iron protective cover can be quickly installed and removed by the magnetic attraction of the ring magnet. Attached Figure Description

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1-4 As shown, an air conditioning water pipe connection device includes a first pipe body 1, a second pipe body 11, and a connection mechanism. Both the first pipe body 1 and the second pipe body 11 are air conditioning water pipes. The annular protruding end 12 can connect the connection point of the first pipe body 1 and the second pipe body 11, thereby increasing the contact area between the first pipe body 1 and the second pipe body 11.

[0024] like Figure 1-3 As shown, the connecting mechanism is located between the first tube 1 and the second tube 11. The annular protrusions 12 of the first tube 1 and the second tube 11 are both provided with guide slopes 13. A pre-compression rubber ring 2 is fitted between the guide slopes 13 of the first tube 1 and the second tube 11. The first tube 1 and the second tube 11 can quickly install the pre-compression rubber ring 2 through the guide slopes 13. Under the guidance and support of the matching guide slopes 13 of the two tubes, the pre-compression rubber ring 2 is not easy to fall off naturally between the first tube 1 and the second tube 11.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the connecting mechanism includes a first flange 3 installed on the outer side of one end of the first pipe body 1, a second flange 31 installed on the outer side of the second pipe body 11, and a fixing mechanism disposed between the first flange 3 and the second flange 31. The annular protruding ends 12 of the first pipe body 1 and the second pipe body 11 abut against the first flange 3 and the second flange 31. The fixing mechanism can connect and fix the first flange 3 and the second flange 31. When the two first flanges 3 and the second flange 31 come close to each other, they can squeeze the annular protruding ends 12 of the first pipe body 1 and the second pipe body 11 against each other, thereby fixing the first pipe body 1 and the second pipe body 11.

[0026] like Figure 1-4 As shown, the second flange 31 has several positioning holes 36 on its side wall, and the first flange 3 has several pre-compression positioning rods 37 fixedly installed at its outer edge and inserted into the positioning holes 36. In the laboratory, the pre-compression test of components such as the pre-compression rubber ring 2 is carried out in advance so that the squeezing pressure of the first pipe body 1 and the second pipe body 11 on the pre-compression rubber ring 2 is within the pressure range that will not leak during the test, and then the corresponding positions of the pre-compression positioning rods 37 and positioning holes 36 are designed.

[0027] During installation, the pre-compression rod 37 is fully inserted into the positioning hole 36 so that the squeezing force of the first pipe body 1 and the second pipe body 11 on the pre-compression rubber ring 2 can reach the pressure that will not leak during the test. This allows the pre-compression rubber ring 2 to be installed and used immediately at the installation site of the air conditioning water pipe connection, thereby eliminating the need to conduct anti-leakage tests on the water pipe connection at the installation site and ensuring that no leakage occurs at the pipe connection during use.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the first flange 3 and the second flange 31 have several fixing holes 32. Fixing bolts 33 are movably installed between the fixing holes 32 of the first flange 3 and the second flange 31. By inserting the pre-pressurized positioning rod 37 into the positioning hole 36, the fixing holes 32 on the first flange 3 and the second flange 31 can be quickly aligned for positioning. This facilitates the subsequent installation and fixing of the first flange 3 and the second flange 31 by passing the fixing bolts 33 and other components through the aligned fixing holes 32.

[0029] like Figure 1 , Figure 3 and Figure 4 As shown, the fixing mechanism includes a gasket 35 movably disposed outside the screw end of the fixing bolt 33 and mating against the outer wall of the first flange 3, and a nut 34 threaded on the outside of the screw end of the fixing bolt 33 for pressing the gasket 35 towards the first flange 3. The nut end of the fixing bolt 33 mating against the outer wall of the second flange 31. By rotating the nut 34 outside the fixing bolt 33, the first flange 3 and the second flange 31 can be brought closer to each other, thereby installing and fixing the components such as the first flange 3 and the second flange 31. The gasket 35 can increase the stability and tightening force of the nut 34 after installation.

[0030] like Figure 1 , Figure 3 and Figure 4As shown, a number of iron protective covers 41 are provided on one side of the first flange 3 to cover the connection between the fixing bolt 33 and the nut 34. A number of ring magnets 4 are fixed on one side of the first flange 3 to magnetically fix the iron protective covers 41. The iron protective covers 41 can cover the connection between the fixing bolt 33 and the nut 34, so that the connection between the fixing bolt 33 and the nut 34 will not be directly exposed to external rainwater and easily corroded. Through the magnetic attraction of the ring magnets 4 to the iron protective covers 41, the iron protective covers 41 can be quickly disassembled and assembled.

[0031] It should be noted that, in use, this air conditioning water pipe connection device first places the pre-compression rubber ring 2 into the guide slope 13 between the first pipe body 1 and the second pipe body 11, and then slowly brings the first pipe body 1 and the second pipe body 11 closer together, so that the first flange 3 and the second flange 31 will slowly approach each other. At this time, the pre-compression positioning rod 37 will slowly insert into the positioning hole 36. Then, the first flange 3 and the second flange 31 are connected by the fixing bolt 33, nut 34 and gasket 35. After the fixing bolt 33 and other components are rotated, the two first flanges 3 and the second flange 31 will approach each other. After the first flanges 3 and the second flange 31 approach each other, they can squeeze the annular protrusions 12 of the first pipe body 1 and the second pipe body 11 against each other, thereby fixing the first pipe body 1 and the second pipe body 11.

[0032] By conducting pre-compression tests on components such as the pre-compression rubber ring 2 in the laboratory, and then fully inserting the pre-compression positioning rod 37 into the positioning hole 36, the squeezing force of the two adjacent first pipe body 1 and second pipe body 11 on the pre-compression rubber ring 2 can reach the pressure that will not leak during the test. This allows the pre-compression rubber ring 2 to be installed and used immediately at the installation site of the air conditioning water pipe connection, thus eliminating the need to conduct anti-leakage tests on the water pipe connection at the installation site and ensuring that no leakage occurs at the pipe connection during use.

[0033] Then the iron protective cover 41 can be placed at the ring magnet 4 and magnetically attracted and fixed. At this time, the iron protective cover 41 can cover the connection between the fixing bolt 33 and the nut 34, so that the connection between the fixing bolt 33 and the nut 34 will not be directly exposed to external rainwater and easily corroded, thereby extending the service life of the fixing bolt 33, the nut 34 and other components.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
