[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Among them, a connecting hole is opened on the upper surface of the mounting seat 1, the connecting hole corresponds to the position of the connecting pipe 2, and the inner diameter of the connecting hole is adapted to the inner diameter of the connecting pipe 2. After the mounting seat 1 is installed, the vacuum gauge body 4 can be connected with the equipment to facilitate measurement.

[0024] See also Figure 2-3 In order to facilitate and intuitively adjust the alarm setting value, the adjustment mechanism 5 in this embodiment includes a glass plate 501, which is fixed to the inner side of the vacuum gauge body 4 so that the value of the vacuum gauge can be observed and the internal pointer of the vacuum gauge can be prevented from being affected. The front side of the glass plate 501 is rotatably connected to a rotating plate 502 through a bearing, and a first spring 503 is fixed to the front side of the rotating plate 502. A turning handle 504 is fixed to the other end of the first spring 503, and a connecting rod 505 is fixed to the back side of the turning handle 504. The back side of the glass plate 501 is rotatably connected to a connecting block 506 through a bearing. The other end of the connecting rod 505 penetrates and extends to the inner side of the connecting block 506, and the outer A mounting groove 507 is provided on the side, and a second spring 508 is fixed to the right inner wall of the mounting groove 507, and a clamping block 509 is fixed to the other end of the second spring 508. A clamping groove 510 is provided on the inner side of the connecting block 506. The turning handle 504 is pressed, and the turning handle 504 drives the connecting rod 505 to move. The connecting rod 505 is inserted into the connecting block 506, so that the second spring 508 bounces the clamping block 509 into the clamping groove 510, so that the connecting rod 505 and the connecting block 506 are connected. At this time, the turning handle 504 is turned, and the turning handle 504 drives the connecting rod 505 to rotate, and the connecting rod 505 drives the connecting block 506 to rotate. An induction component is arranged on the outer side of the connecting block 506.

[0025] In this example, the number of mounting grooves 507 is no less than two, and they are symmetrically distributed around the central axis of the connecting rod 505. The number of slots 510 is equal to the number of mounting grooves 507, and their positions correspond one to one, so that the connection between the connecting rod 505 and the connecting block 506 is more stable.

[0026] It should be noted that the sensing component includes a threshold pointer 511, which is fixed to the outer side of the connecting block 506. The connecting block 506 drives the threshold pointer 511 to rotate, so that the alarm value can be adjusted. After the turning handle 504 is loosened, the first spring 503 moves the connecting rod 505 out of the connecting block 506, so that the position of the threshold pointer 511 cannot be adjusted at will. The rear inner wall of the vacuum meter body 4 is rotatably connected with a rotating rod 512 through a bearing. The outer side of the rotating rod 512 is fixed with an actual value pointer 513, and the front of the actual value pointer 513 is fixed with a signal transmitter 514. A signal receiver 515 is fixed on the back of the value pointer 511. When the actual value pointer 513 on the vacuum gauge body 4 rotates to coincide with the threshold pointer 511, the signal emitted by the signal transmitter 514 is received by the signal receiver 515. At this time, the signal is sent to the alarm 7. The alarm 7 sounds to remind the staff that the length of the actual value pointer 513 is greater than the length of the threshold pointer 511, and the position of the signal transmitter 514 corresponds to the position of the signal receiver 515, so as to avoid overlap between the actual value pointer 513 and the threshold pointer 511, which affects the observation of the staff.

[0027] See also Figure 4 In order to improve the stability of the vacuum gauge during measurement, the support mechanism 6 in this embodiment includes a first hinge seat 601, the first hinge seat 601 is fixed to the outer side of the connecting pipe 3, the inner side of the first hinge seat 601 is hinged with a first support rod 602 through a hinge axis, the angle of the first support rod 602 is adjusted by the first hinge seat 601, a third spring 603 is fixed to the inner top wall of the first support rod 602, the other end of the third spring 603 is fixed to a second support rod 604, and the other end of the second support rod 604 is fixed to the inner top wall of the first support rod 602. The end is hinged with a second hinge seat 605 through a hinge axis, and a suction cup 606 is fixed to the lower surface of the second hinge seat 605. The angle of the suction cup 606 can be adjusted through the second hinge seat 605, so that the suction cup 606 is at a horizontal angle with the surface of the equipment, so as to improve the adsorption of the suction cup 606. If the length is not enough, the third spring 603 can enable the second support rod 604 to be pulled, thereby extending the length between the first support rod 602 and the second support rod 604, so that the vacuum gauge body 4 can be better supported.

[0028] In this example, there are two first articulated seats 601 , which are symmetrically distributed left and right about the central axis of the connecting tube 3 , thereby improving the stability of the vacuum gauge body 4 after installation.

[0029] The working principle of the above embodiment is:

[0030] (1) First, install the mounting base 1 to the surface of the device whose vacuum degree needs to be measured, and then connect the connecting pipe 3 on the vacuum gauge body 4 to the connecting pipe 2, so that the vacuum gauge body 4 can measure the vacuum degree inside the device. Then, adjust the angle of the first support rod 602 through the first hinge seat 601 so that the suction cup 606 is as close to the surface of the device as possible. The angle of the suction cup 606 can be adjusted through the second hinge seat 605 so that the suction cup 606 is at a horizontal angle with the device surface to improve the adsorption of the suction cup 606. If the length is not enough, the third spring 603 can enable the second support rod 604 to be pulled, thereby extending the length between the first support rod 602 and the second support rod 604, so that the vacuum gauge body 4 can be better supported.

[0031] (2) After the vacuum gauge body 4 is properly installed, the alarm threshold of the vacuum gauge can be adjusted. The turning handle 504 is pressed, and the turning handle 504 drives the connecting rod 505 to move. The connecting rod 505 is inserted into the connecting block 506, so that the second spring 508 bounces the card block 509 into the card slot 510, so that the connecting rod 505 and the connecting block 506 are connected. At this time, the turning handle 504 is turned, and the turning handle 504 drives the connecting rod 505 to rotate, and the connecting rod 505 drives the connecting block 506 to rotate. 06 drives the threshold pointer 511 to rotate, so that the alarm value can be adjusted. After loosening the turning handle 504, the first spring 503 moves the connecting rod 505 out of the connecting block 506, so that the position of the threshold pointer 511 cannot be adjusted at will. When the actual value pointer 513 on the vacuum gauge body 4 rotates to coincide with the threshold pointer 511, the signal emitted by the signal transmitter 514 is received by the signal receiver 515. At this time, the signal is sent to the alarm 7, and the alarm 7 sounds an alarm to remind the staff.
