Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning accessories, in particular to a pipe plug for an air-conditioning heat exchanger. Background Art

[0002] Air conditioning equipment needs to transfer part of the heat of the hot fluid to the cold fluid through a heat exchanger and cool the fluid to the temperature required by the user. The heat exchanger is also called a heat exchanger and is widely used in the home appliance industry. A plurality of circular heat exchange tubes are provided on the heat exchanger. After long-term use, the heat exchange tubes will inevitably be damaged and some of the heat exchange tubes will leak. At this time, the staff can use the heat exchange tube plug to seal the leaking part of the tube bundle to avoid affecting the normal operation of other tube bundles. However, the existing tube plug is directly pressed into the pipe mouth by an interference fit, which is not convenient for removing the plug when replacing the tube bundle later. Pressing the plug into the pipe mouth by squeezing is also easy to damage the plug. Therefore, it is necessary to design a tube plug structure that is easy to disassemble and assemble to solve the above problems. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a mounting rod of an air-conditioning heat exchanger pipe plug that is threadedly connected to a rod sleeve. Rotating the mounting rod can make the mounting rod extend into the through groove of the elastic block. The elastic block is provided with multiple internal extrusion grooves, and the diameter of the mounting rod is larger than the diameter of the through groove. The mounting rod contacts the elastic block, causing the elastic block to elastically deform and open outward so that the elastic block can press the pipe mouth. Rotating the mounting rod in the opposite direction can pull the mounting rod out of the through groove. After the elastic block is separated from the mounting rod, it will shrink inward and recover, making it easy to disassemble and use the plug.

[0006] Preferably, a threaded through hole communicating with the through groove is provided at the center of the rod sleeve, and one end of the mounting rod is threadedly connected to the threaded through hole.

[0007] Preferably, a retaining ring and a short rod are provided at one end of the mounting rod away from the rod sleeve, and the short rod is provided with a handle.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so as to provide a clearer understanding of the technical concept to be protected by the present invention.

[0017] like Figures 1 to 4As shown, a pipe plug for an air-conditioning heat exchanger includes a mounting rod 1 and a rod sleeve 2. One side of the rod sleeve 2 is an open structure. An elastic block 3 is provided in the middle of the inner side of the rod sleeve 2. A through groove 4 is provided in the center of the elastic block 3, and a plurality of inner extrusion grooves 5 connected to the through groove 4 are provided on the outer side of the elastic block 3. The diameter of the mounting rod 1 is larger than the diameter of the through groove 4, and one end of the mounting rod 1 is threadedly connected to the rod sleeve 2 and can be extended into the through groove 4 to make the elastic block open to the surroundings.

[0018] The working principle of the air conditioner heat exchanger pipe plug described in the present invention is achieved by the mutual cooperation of the mounting rod 1 and the rod sleeve 2. Figures 1 to 4 As shown, the staff inserts the elastic block into the pipe mouth, and then rotates the mounting rod 1 and extends the mounting rod 1 into the through groove 4 of the elastic block 3. The elastic block is provided with multiple internal extrusion grooves 5, and the diameter of the mounting rod 1 is larger than the diameter of the through groove 4. The elastic block can be made of elastic materials such as rubber. The mounting rod 1 contacts the elastic block so that the elastic block undergoes elastic deformation and gradually opens outward, so that the elastic block gradually presses the pipe mouth, and then the plug is installed on the pipe mouth. Similarly, when removing the plug, the staff rotates the mounting rod 1 in the opposite direction and gradually pulls the mounting rod 1 out of the through groove 4. After the elastic block 3 is separated from the mounting rod 1, it will shrink inward and restore the deformation. Finally, the elastic block can be pulled out from the pipe mouth. Compared with traditional heat exchanger plugs, the elastic block of the air-conditioning heat exchanger pipeline plug can produce elastic deformation and is not easily crushed, which is convenient for disassembly and assembly of the plug.

[0019] Specifically, a plurality of arc-shaped protrusions 6 are provided at intervals on the outer side of the elastic block, and a sealing strip 7 is provided between two adjacent arc-shaped protrusions 6, wherein a threaded through hole communicating with the through groove 4 is provided at the center of the rod sleeve 2, and one end of the mounting rod 1 is threadedly connected to the threaded through hole, wherein a retaining ring 8 and a short rod are provided at the end of the mounting rod 1 away from the rod sleeve 2, and the short rod is provided with a handle 9, as shown in FIG. Figures 1 to 4 As shown, the handle 9 is convenient for the staff to hold the cross bar and rotate the installation rod 1, and when disassembling the plug, the staff can use the hand to resist the ring 8 and then rotate the installation rod 1, so that the installation rod 1 can be quickly inserted into the through groove 4 or pulled out from the through groove 4. A sealing layer can be provided on the outer surface of the elastic block 3. When the arc-shaped protrusion 6 on the elastic block 3 abuts against the inner side of the pipe mouth, the sealing strip 7 can seal the pipe mouth. The sealing layer and the sealing strip 7 can be made of sealing plastic material to improve the sealing performance of the elastic block 3.

[0020] Furthermore, a plurality of external extrusion grooves 10 are evenly arranged on the circumference of the side of the rod sleeve 2 facing away from the mounting rod 1, and a guide block 11 is provided on the outside of the rod sleeve 2 between two adjacent external extrusion grooves 10. Furthermore, a collar 12 is threadedly connected to the side of the outer side of the rod sleeve 2 close to the mounting rod 1, and a guide groove 13 is provided on the side of the collar 12 facing the guide block 11, and parallel guide surfaces are inclined on the sides of the guide groove 13 and the guide block 11 facing each other, as shown in FIG. Figures 1 to 4 As shown, a thread can be provided on the outside of the rod sleeve 2 and threadedly connected to the collar 12. The rod sleeve 2 can be made of elastic materials such as rubber. The external extrusion groove 10 facilitates the elastic deformation of the rod sleeve 2. After the elastic block is inserted into the pipe mouth, the staff can rotate the collar 12, and the collar 12 moves along the rod sleeve 2 toward the guide block 11. The guide groove 13 on the collar 12 and the guide block 11 are abutted through the guide surface, so that the collar 12 drives the part of the rod sleeve 2 provided with the external extrusion groove 10 to shrink inward, thereby pressing one side of the rod sleeve 2 against the outside of the pipe mouth, so that the elastic block 3 can be installed at the pipe mouth through the installation rod 1 after positioning the plug.

[0021] The above are only specific embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
