[0041] The springs 23 are evenly distributed, making the sealing of the second sealing ring 21 more uniform;

[0042] The main body assembly further includes an edge port 11 and a panel 12;

[0043] The edge port 11 is injection - molded and connected to the front side of the housing 10. The panel 12 is glued to the inner side of the edge port 11;

[0044] The edge port 11 provides a position for the panel 12. The panel 12 is used to mount the display screen 13 and the buttons 14;

[0045] The main body assembly further includes a display screen 13 and buttons 14;

[0046] The display screen 13 is embedded in the middle and upper part of the panel 12 by screws. The buttons 14 are movably connected to the middle and lower part of the panel 12 and are located below the display screen 13;

[0047] The display screen 13 and the buttons 14 are electrically connected to the internal electronic components of the housing 10. The instrument can be turned on and off and relevant parameters can be set through the buttons 14. The instrument parameters and working status can be observed through the display screen 13;

[0048] The main body assembly further includes a rear cover 15, a first sealing ring 16 and a mounting plate 17;

[0049] The mounting plate 17 is injection - molded and connected to the inner sides of the four sides at the rear of the housing 10. The first sealing ring 16 and the mounting plate 17 are connected to the mounting plate 17 by screws;

[0050] The rear cover 15 is used to close the housing 10. The first sealing ring 16 plays a sealing role. The mounting plate 17 is used to cooperate with the screws to connect the rear cover 15;

[0051] Threaded holes are opened at the four corners of the rear cover 15. Through - holes are opened at the four corners of the first sealing ring 16. Counter - sunk holes are opened at the four corners of the mounting plate 17. The threaded holes, through - holes and counter - sunk holes correspond one by one.

[0052] Working principle:

[0053] Connect one end of the spring 23 to the side of the second sealing ring 21. Hold the second sealing ring 21 by hand and stuff it into the groove 20 on all four sides, and then stuff the third sealing ring 22 into the inner side of the mounting plate 17.

[0054] The countersunk screw passes through the rear cover 15 and the first sealing ring 16 in sequence, then passes through the mounting hole 24 on the second sealing ring 21, and finally is screwed onto the mounting plate 17.

[0055] The above steps can improve the internal sealing and waterproof effect at the connection between the housing 10 and the rear cover 15, and extend the service life of the sealing ring.

[0061] The fourth sealing ring 32 is connected to the side of the fixing plate 30 by a countersunk screw, and the damper 33 is rotatably connected to the side of the housing 10 and the fixing plate 30;

[0062] The fourth sealing ring 32 functions as a seal, and the damper 33 is used to connect and limit the fixing plate 30.

[0063] Working principle:

[0064] Before installing the rear cover 15, pull up the fixing plate 30 and connect the rear cover 15 to the housing 10 with a countersunk screw;

[0065] Pull the fixing plate 30 to drive the damper 33 to stretch and rotate. When the fixing plate 30 and the fourth sealing ring 32 are against the rear cover 15, the damper 33 contracts, so that the fixing plate 30 and the fourth sealing ring 32 fit against the fixing plate 30;

[0066] At this time, the fourth sealing ring 32 just covers the gap between the rear cover 15 and the housing 10, as well as the installation position of the countersunk screw.

[0067] The above steps can further seal the outside of the rear cover 15 and the housing 10.

[0068] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
