Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, in the embodiment of the present invention, a waterproof and dustproof lever indicator includes a meter body 4 and a measuring rod 5 disposed at the lower end of the meter body 4, wherein both sides of the lower end of the meter body 4 are provided with notches, and both sides of the meter body 4 are provided with notches as installation places, so that the meter is stressed uniformly and prevented from being inclined;

as shown in fig. 2, in order to mount the rotating shaft 8, a hollow part 41 is provided in the middle of the lower end of the watch body 4, the rotating shaft 8 is rotatably mounted inside the hollow part 41, and both ends of the rotating shaft 8 should pass through the hollow part 41 to enter the inside of the double-sided notch;

with reference to fig. 1 and 2, in order to conveniently mount the measuring rod 5, a C-shaped support 10 is arranged below the rotating shaft 8, two ends of the rotating shaft 8 are fixedly connected with two sides of the C-shaped support 10, and an upper end of the measuring rod 5 is fixedly connected with the middle part of the lower surface of the C-shaped support 10, that is, due to the mounting of the C-shaped support 10, under the condition that the lower end of the measuring rod 5 is stressed, the thrust applied to the measuring rod can be uniformly distributed on the rotating shaft 8 by the C-shaped support 10, so that the two ends of the rotating shaft 8 can be uniformly stressed, and the rotating shaft 8 is ensured not to be inclined, inclined or inclined, and the like, so as to ensure the detection accuracy;

as shown in fig. 2, in order to ensure the sealing between the rotating shaft 8 and the side wall of the hollow portion 41, a metal sealing ring 12 is arranged between the gap between the two side walls of the hollow portion 41 and the rotating shaft 8, the metal sealing ring 12 does not deform, and the inaccurate detection caused by the slight change of the position of the rotating shaft 8 due to the arrangement of the flexible sealing ring is avoided;

with continued reference to fig. 2, in order to further ensure the sealing effect, a rubber gasket 11 is installed between the inner side of the C-shaped bracket 10 and the outer side of the hollow portion 41 outside the circumference of the rotating shaft 8, and the rubber gasket 11 fills the space between the C-shaped bracket 10 and the outer side of the hollow portion 41, thereby further avoiding the entry of water and ash;

in order to facilitate detection, the lower end of the measuring rod 5 is convenient to contact a workpiece to be detected, and a measuring head 6 is fixedly connected to the lower end of the measuring rod 5;
