[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 This utility model provides a technical solution: an airtightness testing device, including a testing tube 1 for installing a connector 4 and a fixing frame 2 fixed to the lower end of the testing tube 1, and further including:

[0027] Mounting holes 101 are spaced apart on the end face of the detection tube 1;

[0028] Hollow screw 5, threaded connection mounting hole 101 and used for mounting connector 4;

[0029] The sealing device 6 is located at one end of the connector 4 and is used to seal the connector 4.

[0030] It should be noted that during operation, connector 4 is fitted onto hollow screw 5, and then hollow screw 5 is fixed in mounting hole 101 on detection tube 1. After connector 4 fills mounting hole 101, detection tube 1 is placed in water and fixed in a set position in the water by fixing bracket 2. At this time, gas is injected into the inside of detection tube 1. Whether air bubbles are generated at connector 4 is used to determine whether connector 4 is leaking. The connection between hollow screw 5 and connector 4 is sealed. The design of mounting hole 101 and hollow screw 5 can quickly fix connectors 4 of different specifications onto detection tube 1, greatly improving detection efficiency. The threaded connection also ensures the stability and reliability of fixing connector 4 to detection tube 1. Sealing device 6 can seal and fix a row of connectors 4 at one time, greatly improving the sealing efficiency of connector 4, thereby speeding up the detection efficiency of connector 4 and enhancing the versatility and practicality of the equipment.

[0031] In one embodiment, the sealing device 6 includes a sealing block 62 inserted on the side of the connector 4 away from the detection tube 1, the sealing block 62 abutting against the inner wall of the connector 4.

[0032] This design is for reference. Figure 6 When sealing the connector 4, the sealing block 62 is inserted into the interior of the connector 4. The sealing block 62 fits tightly against the inner wall of the connector 4 to form an effective seal, preventing gas or liquid from leaking during the test and ensuring the accuracy and reliability of the airtightness test.

[0033] In one embodiment, the sealing device 6 further includes a connecting plate 61 fixed on the side of the sealing block 62 away from the connector 4 and a fixing mechanism 63 fixed on the connecting plate 61 for fixing the connecting plate 61 to the connector 4. The connecting plate 61 is fixedly connected to a plurality of sealing blocks 62.

[0034] This design is for reference. Figure 4-7 Multiple sealing blocks 62 are fixed together by connecting plate 61 to form an integral structure. Since multiple sealing blocks 62 are fixed together by connecting plate 61, they can seal a row of joints 4 at the same time, which improves the sealing efficiency of joints 4 and facilitates unified management and maintenance of sealing device 6, thus improving work efficiency.

[0035] In one embodiment, the fixing mechanism 63 includes a support plate 631 fixed on the connecting plate 61, an adjusting screw 632 threadedly connected to the support plate 631, and a fixing plate 634 sleeved on the joint 4 and rotatably connected to the adjusting screw 632. A rotating rod 633 is provided on the side of the adjusting screw 632 away from the connecting plate 61.

[0036] This design is for reference. Figure 4-7 By rotating the adjusting screw 632, the tightness between the fixing plate 634 and the connector 4 can be precisely adjusted to accommodate connectors 4 of different sizes and shapes. This design provides high adjustment flexibility, ensuring effective fixation of the sealing device 6 in various application scenarios. The fixing plate 634 is fitted onto the connector 4, and then the rotating rod 633 is rotated, causing the adjusting screw 632 to be threadedly connected to the support plate 631. This moves the fixing plate 634 closer to the support plate 631, thereby fixing the fixing plate 634 and the connector 4, ensuring the stability of the fixing of the sealing block 62 and the connector 4.

[0037] In one embodiment, the fixing plate 634 is arc-shaped and fits against the outer side of the connector 4.

[0038] This design is for reference. Figure 7 The arc-shaped design of the fixing plate 634 can better fit the outer curved surface of the connector 4. This close fit helps to enhance the stability between the fixing mechanism 63 and the connector 4. During airtightness testing or other work processes, when the connector 4 is subjected to external force or changes in internal pressure, the fixing plate 634 can provide additional support and fixation to prevent the connector 4 from shifting or loosening.

[0039] In one embodiment, a connecting pipe 3 connected to an external inflation device is provided on one side of the detection tube 1, and an air outlet 51 is provided at the position of the hollow screw 5 inside the connector 4.

[0040] This design is for reference. Figure 3The detection tube 1 can be easily connected to an external inflation device through the connecting tube 3, thereby achieving rapid inflation. The air outlet 51 opened at the position of the hollow screw 5 inside the connector 4 can ensure that the gas is smoothly transmitted from the external inflation device to the detection tube 1.
