[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the following specific embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of this utility model, and should not be regarded as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model.

[0022] Reference Figures 1-5 As shown, this utility model provides a technical solution: an airtightness testing cabinet, including a testing cabinet mechanism 1: a slide rail 2 is installed at the top of the testing cabinet mechanism 1, a moving platform 3 is installed at the top of the slide rail 2, a testing cabinet body 4 is set at the top of the moving platform 3, fixing blocks 5 are fixedly connected to both sides of the testing cabinet body 4, an adjusting box 6 is fixedly connected inside the fixing blocks 5, an adjusting groove 7 is opened inside the adjusting box 6, an adjusting column 8 is rotatably connected inside the adjusting groove 7, a positioning rod 9 is set inside the adjusting column 8, arc-shaped blocks 10 are fixedly connected to both ends inside the adjusting groove 7, and adjusting holes 11 are opened at both ends of the adjusting column 8, and the adjusting holes 11 are internally connected to the adjusting groove 7. A sliding push post 12 is connected, and an insertion rod 13 is fixedly connected to the side of the push post 12 near the inside of the adjustment hole 11. The positioning rod 9 has several insertion holes 25 inside. The operator places the test object inside the test cabinet body 4 and moves the positioning rod 9 to fit the test object of different specifications. After adjusting the applicable position of the positioning rod 9, the operator rotates the adjustment post 8, which causes the adjustment post 8 to drive the push post 12 and the insertion rod 13 to move. When the push post 12 contacts the arc block 10, the push post 12 gradually pushes the arc block 10 to drive the adjustment hole 11 to be inserted into the inside of the insertion hole 25, thereby limiting the positioning rod 9 and achieving the positioning function.

[0023] Reference Figure 2 and Figure 5 As shown, in this embodiment, the size of the insertion rod 13 is adapted to the size of the insertion hole 25, and the surface of the insertion rod 13 is inserted into the interior of the insertion hole 25. By adapting the size of the insertion rod 13 to the size of the insertion hole 25, the insertion rod 13 can be stably inserted into the interior of the insertion hole 25, and it is not easy to fall out, thus enhancing the overall stability.

[0024] Reference Figure 5 As shown in this embodiment: a return spring 14 is fixedly connected to the side of the push post 12 near the insertion rod 13, and the side of the return spring 14 away from the push post 12 is fixedly connected to the inside of the adjustment hole 11. When the operator moves the push post 12 into the adjustment hole 11, the push post 12 compresses the return spring 14 to store force, and drives the insertion rod 13 into the insertion hole 25. When the operator releases the push post 12, the push post 12 quickly returns to its original position under the action of the return spring 14, so that the insertion rod 13 is stably locked inside the insertion hole 25, ensuring the positioning accuracy and stability of the positioning rod 9.

[0025] Reference Figure 3 and Figure 4 As shown in this embodiment: two annular grooves 15 are formed inside the adjusting groove 7, and two annular blocks 16 are fixedly connected to the outer diameter surface of the adjusting column 8. The surface of the annular blocks 16 is slidably connected to the inside of the annular grooves 15. When the operator rotates the adjusting column 8 inside the adjusting groove 7, the adjusting column 8 drives the annular blocks 16 to slide inside the annular grooves 15. Through the above arrangement, the stability of the adjusting column 8 rotating inside the adjusting groove 7 can be improved by sliding connection during use, avoiding shaking or deviation during rotation, and ensuring the accuracy and performance of the overall device.

[0026] Reference Figure 5 As shown in this embodiment: guide grooves 17 are provided at both ends of the adjustment hole 11, and guide blocks 18 are fixedly connected to both ends of the push column 12. The surface of the guide block 18 is slidably connected to the inside of the guide groove 17. When the operator moves the push column 12, the push column 12 drives the guide block 18 to slide inside the guide groove 17. Through the above settings, the stability of the push column 12 moving inside the adjustment hole 11 can be improved by sliding connection during use, avoiding jamming or deviation from the track during movement, and further optimizing the smoothness of operation and the effect of use of the overall device.

[0027] Reference Figure 4 and Figure 5As shown in this embodiment: control slots 19 are provided at both ends of the adjusting column 8. Insertion blocks 22 are slidably connected inside the control slots 19. A return spring 20 is fixedly connected to the side of the insertion block 22 near the inside of the control slot 19. The side of the return spring 20 away from the insertion block 22 is fixedly connected to the inside of the control slot 19. Insertion holes 23 are provided at both ends of the adjusting box 6. When the operator rotates the adjusting column 8 to insert the insertion rod 13 into the insertion hole 25, the adjusting column 8 simultaneously makes the position of the control slot 19 parallel to the insertion hole 23. Under the action of the return spring 20, the insertion block 22 is quickly pushed into the insertion hole 23, thus limiting the position of the adjusting column 8 and preventing it from rotating.

[0028] Reference Figure 5 As shown in this embodiment: sliding grooves 21 are provided at both ends of the control groove 19, and sliding blocks 24 are fixedly connected to both ends of the insertion block 22. The surface of the sliding block 24 is slidably connected to the inside of the sliding groove 21. When the operator moves the insertion block 22 inside the control groove 19, the insertion block 22 drives the sliding block 24 to slide inside the insertion hole 25. Through the above arrangement, the overall device can enhance the stability of the insertion block 22 moving inside the control groove 19 through the sliding connection, ensuring that there will be no shaking or stopping during the movement, and further improving the operational stability and performance of the overall device.

[0029] Working principle: The operator places the object to be tested inside the testing cabinet body 4 and moves the positioning rod 9 to fit the object of different specifications. After adjusting the position of the positioning rod 9, the operator rotates the adjusting column 8, which moves the pushing column 12 and the insertion rod 13. When the pushing column 12 contacts the arc block 10, the pushing column 12 gradually pushes the arc block 10, causing the adjusting hole 11 to be inserted into the insertion hole 25, thus limiting the positioning rod 9 and achieving the positioning function. Through the matching of the size of the insertion rod 13 with the size of the insertion hole 25, the insertion rod 13 can be stably inserted into the insertion hole 25, making it less likely to fall out, thus enhancing the overall performance. To ensure stability, when the operator moves the push column 12 into the adjusting hole 11, the push column 12 compresses the return spring 14 to store force, driving the insertion rod 13 into the insertion hole 25. When the operator releases the push column 12, it quickly returns to its original position under the rebound force of the return spring 14, ensuring that the insertion rod 13 is stably engaged inside the insertion hole 25, thus guaranteeing the positioning accuracy and stability of the positioning rod 9. When the operator rotates the adjusting column 8 inside the adjusting groove 7, the adjusting column 8 drives the ring block 16 to slide inside the annular groove 15. Through the above settings, the entire device can improve stability during use through a sliding connection. The stability of the adjusting column 8's rotation within the adjusting groove 7 is ensured, preventing wobbling or deviation during rotation and guaranteeing the overall device's accuracy and performance. When the operator moves the push column 12, the push column 12 drives the guide block 18 to slide within the guide groove 17. This design allows the entire device to move stably within the adjusting hole 11 via a sliding connection, preventing jamming or deviation from the track during movement. This further optimizes the smoothness of operation and performance of the entire device. When the operator rotates the adjusting column 8 to insert the insertion rod 13 into the insertion hole 25, the adjusting column 8 simultaneously... The position of the control groove 19 is parallel to the insertion hole 23, and the insertion block 22 is quickly pushed into the insertion hole 23 under the action of the return spring 20. The position of the adjusting column 8 is limited to prevent rotation. When the operator moves the insertion block 22 inside the control groove 19, the insertion block 22 drives the sliding block 24 to slide inside the insertion hole 25. Through the above settings, the overall device can enhance the stability of the movement of the insertion block 22 inside the control groove 19 through the sliding connection, ensuring that there will be no shaking or stopping during the movement, and further improving the operational stability and performance of the overall device.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
