Description

Technical Field

[0001] The utility model relates to the technical field of air tightness detectors, in particular to a locking structure of an air tightness detector. Background Art

[0002] The airtightness tester is used to detect the airtightness of an object. During the test, the object to be tested is placed in the test box, and then the test data is observed through the change of air pressure to detect the airtightness of the object to be tested.

[0003] According to observations based on existing testing equipment, the location of the pipeline connection of the detector is mostly to insert the pipeline into the connector, and then add gas or extract gas to control the air pressure in the test box. However, when the air pressure is controlled, there is a certain pressure at the connector and the pipeline connector. The pressure comes from the expansion of the pipeline during inflation. The expanded pipeline may have a gap with the connector, causing gas leakage. Gas leakage may weaken the ability to control air pressure, resulting in inaccurate test data. When gas is extracted, a pulling force will be generated at the connection between the pipeline and the connector, and the pulling force will drive the pipeline to separate from the connector. After separation, the unfiltered gas is likely to enter the equipment, causing the precision parts of the equipment to be contaminated, thereby affecting the service life of the equipment.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be noted that the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.

[0023] It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention.

[0024] The following describes an air tightness detector locking structure provided by some embodiments of the utility model in conjunction with the accompanying drawings.

[0025] Combination Figure 1-4 As shown, the utility model provides a locking structure of an airtightness detector, comprising a box body 1, a connector 2 is symmetrically slidably connected to one side of the box body 1, a first connecting rod 3 is annularly fixedly connected to one side of the connecting head 2, the first connecting rod 3 is L-shaped, one end of the first connecting rod 3 is fixedly connected to a rotating ring 4, the inner wall of the rotating ring 4 is annularly fixedly connected to a second connecting rod 5, one end of the second connecting rod 5 is fixedly connected to a bearing ring 6, the outer wall of the bearing ring 6 is fixedly connected to a threaded strip 7, and the inner wall of the connecting head 2 is slidably connected to a support ring 9;

[0026] The second connecting rod 5 is arranged in an L shape, and the number of the second connecting rods 5 is six. A control panel 19 is fixedly connected to one side of the box body 1, and a detection box 15 is symmetrically fixedly connected to the top of the box body 1. A cover plate 16 is slidably connected to one side of the detection box 15 in a through-shaped manner, and a support plate 17 is symmetrically fixedly connected to the bottom of the cover plate 16, and a sealing strip 18 is fixedly connected to one side of the support plate 17.

[0027] In the first embodiment, the pipeline is first inserted into the connector 2, and then the connector 2 is rotated to drive the first connecting rod 3 to rotate. When the first connecting rod 3 rotates, it can drive the rotating ring 4 to rotate. When the rotating ring 4 rotates, it can drive the bearing ring 6 on the second connecting rod 5 to rotate. When the bearing ring 6 rotates, it can drive the threaded bar 7 to move. The movement of the threaded bar 7 can transport the pipeline joint on the bearing ring 6 to the depth of the connector 2, which can increase the formation of the pipeline in the connector 2. If displacement occurs, the separation of the pipeline and the connector 2 can be avoided. In this way, it can be ensured that the extracted gas is always pure gas filtered by the pipeline filter, and impurities are prevented from entering the equipment, thereby ensuring that the equipment can be used normally and extending the service life of the equipment.

[0028] The side wall of the rotating ring 4 is annular and is slidably connected with a sliding rod 8. A sliding ring 10 is provided at one end of the sliding rod 8. One end of the sliding ring 10 is slidably connected with a moving block 11. One end of the moving block 11 is fixedly connected with a clamping ring 14. The side wall of the sliding ring 10 is symmetrically fixedly connected with a limiting block 20. One side of the limiting block 20 is slidably connected with a pin 21. The sliding ring 10 is slidably connected to the inner wall of the support ring 9. One end of the pin 21 is slidably connected to the inner wall of the connecting head 2. Both sides of the moving block 11 are fixedly connected with partitions 12. One side of the partition 12 is fixedly connected with a spring 13. The spring 13 is fixedly connected to the inner wall of the connecting head 2.

[0029] In the second embodiment, after the pipeline is connected, the connector 2 is pressed, and the sliding rod 8 will push the sliding ring 10 to move. The sliding ring 10 will squeeze the moving block 11 when moving. The movement of the moving block 11 will drive the clamping ring 14 to move and clamp the pipeline. Then, the latch 21 is rotated to allow the latch 21 to enter the limit block 20 to complete the locking. This can ensure that when the pipeline is inflated or deflating to control the air pressure, no gap will be generated due to the deformation of the pipeline, and no gas leakage will occur, thereby ensuring the accuracy of air pressure regulation, which can ensure the accuracy of detection data.

[0030] The working principle and use process of the utility model are as follows: insert the pipe into the connector 2, then rotate the connector 2, let the connector 2 drive the second connecting rod 5 on the rotating ring 4 to move through the first connecting rod 3, the second connecting rod 5 drives the threaded strip 7 on the bearing ring 6 to move, when the threaded strip 7 moves, it can drive the pipe to move deeper into the connector 2, then press the connector 2 to let the sliding rod 8 push the sliding ring 10 to move, the sliding ring 10 pushes the moving block 11 to move, when the moving block 11 moves, it can drive the clamping ring 14 to clamp and seal the pipe, then rotate the latch 21, let the latch 21 enter the limit block 20 to complete the locking, after releasing the latch 21, the spring 13 will drive the parts to reset, so that the pipe can be disassembled.

[0031] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
