Technical Field

[0001] The utility model relates to the technical field of radiator detection, in particular to a quick-install joint for radiator air tightness detection. Background Art

[0002] During the manufacturing of radiators, each set of radiators is assembled from a single piece, and each radiator fin is welded from pipe fittings. Whether the welded radiator fins leak, the pressure resistance, and whether the radiator as a whole leaks after assembly will directly affect the use of the entire radiator. Therefore, it is necessary to conduct airtightness testing on the finished radiator.

It takes about 1 minute to install a thread, and about 5 minutes for a group of products. The test is quite time-consuming and laborious. Therefore, a quick-release connector for radiator air tightness testing is proposed. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] The utility model provides a technical solution: Figures 1 to 4As shown, in the present embodiment, a quick-release connector for detecting air tightness of a radiator comprises a radiator body 1 and a connector body 3. Four pipe openings 2 are arranged on the radiator body 1. The four connector bodies 3 correspond to the four pipe openings 2 one by one. The connector body 3 consists of a sealing tube 4 and an expansion piece 6. The sealing tube 4 is made of elastic material. The outer wall of the sealing tube 4 is slidably fitted with the inner wall of the pipe opening 2. A positioning plate 5 is fixedly connected to the outer wall of the sealing tube 4. The positioning plate 5 is made of cemented carbide. The expansion piece 6 is connected to the positioning plate 5 through a connecting assembly. The middle part of the expansion piece 6 is a truncated cone body. The two ends of the truncated cone body are respectively fixedly connected with cylinders with the same diameter as the table top. A through hole 10 is opened at the axial position of an expansion piece 6 and passes through it, and the end of the expansion piece 6 away from the sealing tube 4 is fixedly connected with a water pipe head 11.

[0021] When in use, the joint body 3 connected with the water pipe head 11 is used for water inlet detection, and the other three joint bodies 3 are used for sealing. When installing the joint body 3, the sealing tube 4 of the joint body 3 is slidably inserted into the pipe mouth 2 of the radiator body 1, and the positioning plate 5 can play a positioning effect to prevent the sealing tube 4 from being completely immersed in the interior of the pipe mouth 2. Then, the expansion piece 6 is inserted into the interior of the sealing tube 4 with force. The middle part of the expansion piece 6 is a truncated cone structure. As the expansion piece 6 is inserted, the expansion piece 6 will gradually open the sealing tube 4, and the sealing tube 4 is made of elastic material, which will make the sealing tube The outer wall of 4 fits tightly against the inner wall of the pipe mouth 2, and the inner wall of the sealing tube 4 fits tightly against the outer wall of the expansion piece 6, thereby achieving a sealing effect. When the cylindrical structure at the tail of the expansion piece 6 enters the interior of the expansion piece 6, the deformation of the sealing tube 4 reaches the extreme, and the sealing effect is best at this time. At the same time, since the cylindrical structure at the tail of the expansion piece 6 is in contact with the sealing tube 4 at this time, the squeezing force of the sealing tube 4 on the expansion piece 6 can lock the expansion piece 6, thereby preventing the expansion piece 6 from falling off. The installation method of the joint body 3 is simple and convenient, and can effectively improve work efficiency.

[0022] Among them, the connecting component includes a mounting plate 7, a guide rod 8 and a limit block 9. The mounting plate 7 is sleeved on the outer surface of the expansion member 6. A plurality of guide rods 8 are fixedly connected to one end of the mounting plate 7 close to the positioning plate 5. The plurality of guide rods 8 are distributed in a ring shape with equal intervals. The guide rods 8 slide through the guide groove 12 opened on the positioning plate 5, and the end of the guide rod 8 is fixedly connected to the limit block 9.

[0023] The connection assembly can prevent the expansion member 6 from being separated from the sealing tube 4.

[0024] The utility model provides a quick-release connector for radiator air tightness detection, and the specific working principle is as follows:

[0025] When in use, the joint body 3 connected with the water pipe head 11 is used for water inlet detection, and the other three joint bodies 3 are used for sealing. When installing the joint body 3, the sealing tube 4 of the joint body 3 is slidably inserted into the pipe mouth 2 of the radiator body 1, and the positioning plate 5 can play a positioning effect to prevent the sealing tube 4 from being completely immersed in the interior of the pipe mouth 2. Then, the expansion piece 6 is inserted into the interior of the sealing tube 4 with force. The middle part of the expansion piece 6 is a truncated cone structure. As the expansion piece 6 is inserted, the expansion piece 6 will gradually open the sealing tube 4, and the sealing tube 4 is made of elastic material, which will make the sealing tube The outer wall of 4 fits tightly against the inner wall of the pipe mouth 2, and the inner wall of the sealing tube 4 fits tightly against the outer wall of the expansion piece 6, thereby achieving a sealing effect. When the cylindrical structure at the tail of the expansion piece 6 enters the interior of the expansion piece 6, the deformation of the sealing tube 4 reaches the extreme, and the sealing effect is best at this time. At the same time, since the cylindrical structure at the tail of the expansion piece 6 is in contact with the sealing tube 4 at this time, the squeezing force of the sealing tube 4 on the expansion piece 6 can lock the expansion piece 6, thereby preventing the expansion piece 6 from falling off. The installation method of the joint body 3 is simple and convenient, and can effectively improve work efficiency.
