Problems solved by technology

[0004] However, in the prior art, glue sticks are used as inflatable plugs, and it is difficult to ensure a certain sealing effect between the glue sticks and the nozzle of the special water chamber. During the detection process, as the air pressure increases, the glue stick plugs will collapse. It is difficult to guarantee the reliability of the plug connection during the test, resulting in low detection efficiency and large detection errors

Embodiment 1

[0040] Please also see figure 2 and image 3 , the present invention provides a special fast inflation joint for the special water chamber water inspection of the tube belt type automobile radiator, which mainly includes an inner sleeve 1, which is used to connect with the nozzle of the water chamber, and the inner sleeve 1 The position where the lower end is connected with the nozzle of the water chamber is provided with a ball plunger 4; an outer sleeve 2, which is set on the outside of the inner sleeve 1, is used to lock the inner sleeve 1 and the nozzle of the water chamber. Connection; also includes a connecting assembly 3, which is used to connect the outer sleeve 2 to the inner sleeve 1, and enables the outer sleeve 2 to move up and down on the outer surface of the inner sleeve 1, so that the inner sleeve 1 is in the open or locked state. During use, the outer sleeve 2 is slid to the bottom to play a locking role. After the detection is completed, the outer sleeve 2...

Embodiment 2

[0046] Please also see figure 1 , Figure 4 with Figure 5 , on the basis of the first embodiment above, and different from the first embodiment above, in order to improve the sealing performance of the special quick inflation joint, a sealing assembly 5 is also included in the inner cavity of the inner sleeve 1, and the sealing assembly 5 It is used to block the nozzle of the special water chamber of the automobile radiator to ensure good airtightness during the detection process. Specifically, the sealing assembly 5 includes a sealing spring 51, a sealing block 52 and an O-shaped sealing rubber ring 53, wherein one end of the sealing spring 51 Butt against the inner surface of the inner sleeve 1, and the other end of the sealing spring 51 abuts against the upper end surface of the sealing block 52; The effect of making the sealing block 52 drives the sealing rubber pad 54 to be closely attached to the upper end of the water chamber nozzle, and further plays a sealing role....

Embodiment 3

[0050] Please also see Figure 1-9 , and the above-mentioned embodiment 1 and embodiment 2 are different in that the joint of this embodiment is an inflatable joint, and a flow channel 32 for gas to enter the inner sleeve 1 is opened on the connecting component 3, and the flow channel 1 32 is arranged throughout the connecting assembly 3 , and a connecting groove 33 is opened on the connecting assembly 3 above the flow channel 1 32 for connecting with an air source. Preferably, the connection groove 33 is set as a thread groove, which not only achieves the purpose of detachment, but also prevents the gas from flowing back from the gap of the connection groove 33 when inflated. In actual use, an M10*1.0 joint is equipped in the thread groove. Under the premise of ensuring the sealing performance, it is connected with the gas source for inflating; in addition, the second flow channel 55 for the passage of gas is opened on the sealing assembly 5 , and the second flow channel 55 i...

Abstract

The invention relates to the technical field of automobile radiators, and discloses a quick inflation connector special for water inspection of a special water chamber of a pipe belt type automobile radiator. The quick inflation connector comprises an inner sleeve used for being connected with a water chamber nozzle, an outer sleeve arranged on the outer side of the inner sleeve in a sleeving modeand used for locking connection between the inner sleeve and the water chamber nozzle and a connecting assembly used for connecting the outer sleeve to the inner sleeve and enabling the outer sleeveto move up and down on the outer side surface of the inner sleeve; and a ball plunger is arranged at the lower end of the inner sleeve and used for being matched with the outer sleeve for locking. Thequick inflation connector is simple in structure, convenient to install and low in manufacturing cost, the connection efficiency and reliability of the connector are remarkably improved, the accuracyof a detection result is guaranteed, and the product yield and the detection efficiency are improved. The defect that in the prior art, a glue stick serves as an inflation plug is effectively overcome.

Description

technical field [0001] The invention relates to the technical field of automobile radiators, in particular to a fast inflation joint specially used for water inspection of a special water chamber of a pipe-belt type automobile radiator. Background technique [0002] The car radiator is an important system used for the temperature control of the car engine. The medium (liquid or gas) running inside it takes away heat through the heat exchange with the external cooling air to reduce the temperature. Once the medium running inside leaks, it will cause heat exchange. The failure of the car will cause the car to fail to operate normally and even cause the cylinder to be seized and scrapped. [0003] Therefore, its airtightness directly affects the overall effect of the car engine, which reflects the importance of car radiator detection from the side. At present, when testing the air tightness of automobile radiators, two testing methods are used, namely dry leak detection and we...
