[0044] It should be noted that the detector body 1 is a differential pressure (high pressure) leak detector of the existing model CH-4000, which is used to test the airtightness of products; the protective plate 3 is a plate with a groove on one side. When it is necessary to protect the panel of the detector body 1, the side of the protective plate 3 with the groove faces the detector body 1 to prevent the protective plate 3 from being pressed on the buttons of the detector body 1; the stop blocks 2 are respectively fitted at the eight corners of the detector body 1, and the eight corners of the detector body 1 are protected by the stop blocks 2.

[0045] Specifically, fixed component 4 includes:

[0046] Positioning plate 406 is provided on one side of the detector body 1. A sliding member 5 for adjusting the position of positioning plate 406 is provided at the connection between positioning plate 406 and detector body 1.

[0047] Fixing block 408 is fixedly connected to the front of the protective plate 3;

[0048] Card slot 402 is located on the front of positioning plate 406;

[0049] The card block 401 is inserted into the inside of the card slot 402. The fixing block 408 has a through hole on one side, and the card block 401 is inserted into the inside of the through hole.

[0050] A movable component is provided on one side of the card block 401, and the movable component is used to move the position of the card block 401.

[0051] It should be noted that there are two positioning plates 406, which are respectively set on both sides of the detector body 1. The sliding member 5 is used to move the position of the positioning plate 406. The slot 402 opened on the positioning plate 406 is adapted to the slot 401 that is inserted into the fixed block 408. Both of them have a semi-circular horizontal and vertical cross section. When it is necessary to fix the position of the protective plate 3, the slot 401 is inserted into the slot 402, so that the slot 401 is inserted into the positioning plate 406 and the fixed block 408 respectively. The slot 401 blocks the movement of the fixed block 408, and the position of the protective plate 3 is fixed by the fixed block 408 that restricts the movement.

[0052] Specifically, the moving parts include:

[0053] Connecting plate 403 is fixedly connected to one side of the locking block 401;

[0054] Connecting rod 407 is fixedly connected to one side of the locking block 401;

[0057] Specifically, a cavity 405 is provided on the inner wall of the through hole side, and the connecting plate 403 and the spring 404 are both inserted and connected inside the cavity 405. The connecting rod 407 is inserted and connected to the inner wall of the cavity 405 side. A limiting member 6 is provided at the connection between the cavity 405 and the connecting plate 403.

[0058] It should be noted that the connecting plate 403 is adapted to the cavity 405, allowing the connecting plate 403 to slide inside the cavity 405. The connecting rod 407 is inserted into the inner wall of one side of the cavity 405, and connects the connecting plate 403 inside the cavity 405 and the pulling block 409 outside the cavity 405. When the position of the locking block 401 needs to be moved, the connecting rod 407, the connecting plate 403 and the locking block 401 are moved directly by the pulling block 409. The spring 404 is used to push the connecting plate 403, thereby preventing the connecting plate 403 and the locking block 401 from moving arbitrarily.

[0059] Furthermore, when it is necessary to fix the position of the protective plate 3, first move the protective plate 3 to the front of the detector body 1, and use the pulling block 409 to drive the connecting rod 407, connecting plate 403 and locking block 401 to move, so that the locking block 401 moves into the through hole. Then move the position of the protective plate 3 so that it is in contact with the detector body 1. Release the pulling block 409, and use the force of the spring 404 to push the connecting plate 403 and locking block 401, and push the locking block 401 into the slot 402 to fix the position of the protective plate 3.

[0060] Specifically, limiting component 6 includes:

[0061] Slider 602 is fixedly connected to the inner wall of the front side of cavity 405;

[0062] The slide 601 is formed on the front of the connecting plate 403, and the slider 602 is inserted and connected inside the slide 601.

[0063] It should be noted that the groove 601 is adapted to the slider 602, so that the connecting plate 403 can be fitted onto the slider 602 through the groove 601, and the slider 602 blocks the connecting plate 403 from sliding freely inside the cavity 405.

[0064] Example 2:

[0065] A pipeline airtightness tester, comprising:

[0066] The detector body 1 has multiple blocks 2 symmetrically fixedly connected to both sides of the detector body 1. The blocks 2 are used to protect the detector body 1.

[0067] Protective plate 3 is installed on the front of the detector body 1 and is used to protect the detector body 1.

[0068] Fixing component 4 is located at the connection between the detector body 1 and the protective plate 3. Fixing component 4 is used to install and separate the detector body 1 and the protective plate 3.

[0069] Specifically, fixed component 4 includes:

[0070] Positioning plate 406 is provided on one side of the detector body 1. A sliding member 5 for adjusting the position of positioning plate 406 is provided at the connection between positioning plate 406 and detector body 1.

[0071] Fixing block 408 is fixedly connected to the front of the protective plate 3;

[0072] Card slot 402 is located on the front of positioning plate 406;

[0073] The card block 401 is inserted into the inside of the card slot 402. The fixing block 408 has a through hole on one side, and the card block 401 is inserted into the inside of the through hole.

[0078] A retaining ring 501 is provided on one side of the positioning plate 406 and is fixedly connected to one side of the guide block 502. The horizontal longitudinal section of both the guide groove 503 and the guide block 502 is set to square, and the guide block 502 is used to restrict the rotation of the guide groove 503.

[0079] It should be noted that the horizontal longitudinal section of both the guide groove 503 and the guide block 502 is square, and the top and bottom of the guide block 502 are respectively fitted to the inner walls of the top and bottom of the guide groove 503. This prevents the positioning plate 406 from rotating when it is fitted onto the guide block 502 through the guide groove 503. When it is necessary to move the positioning plate 406, the guide block 502 restricts the direction of movement of the positioning plate 406. The positioning plate 406 is located between the retaining ring 501 and the detector body 1, and the retaining ring 501 restricts the positioning plate 406 from moving away from the detector body 1.

[0080] Furthermore, when it is necessary to fix the position of the protective plate 3, the positioning plate 406 is moved to one side of the protective plate 3. After the protective plate 3 is removed from the detector body 1, the positioning plate 406 is moved to the side away from the protective plate 3 to avoid the positioning plate 406 protruding and being bent.

[0081] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
