[0043] The upper end of each second rod 20 extends through the side wall of the upper cover cap 6 and into the third annular groove 17, and the side wall of the second rod 20 in the third annular groove 17 is fixedly connected with a first bevel gear 21.

[0044] The side wall of each second rod 20 in the second annular groove 10 is fixedly connected with a gear 24, and the side wall of the rotating ring 14 is fixedly connected with two arc-shaped toothed plates 23.

[0045] When the rotating ring 14 is rotated forward, the two arc-shaped toothed plates 23 can drive the two second rods 20 to rotate forward through the two gears 24, and the two lead screws 19 are driven to rotate forward through the first bevel gear 21 and the second bevel gear 22, so that the two semicircular plates 18 are close to each other, and the inner side walls of the two semicircular plates 18 are attached to the outer side wall of the circular ring 5 (it should be noted that the inner side walls of the two semicircular plates 18 are provided with sealing pads).

[0047] The side wall of the upper cover cap 6 is slidably connected with a second T-shaped plate 30 (as shown in Figure 8 The lower end of the second T-shaped plate 30 extends into the arc-shaped groove 25, the upper end of the first T-shaped plate 26 is provided with a clamping groove 32 corresponding to the second T-shaped plate 30, and the upper end of the upper cover cap 6 is elastically connected with the lower end of the second T-shaped plate 30 through a plurality of second springs 31.

[0048] Before the first T-shaped plate 26 is rotated forwardly, the second T-shaped plate 30 is pulled upwardly to move out of the arc-shaped slot 25, and after the plurality of fixing plates 13 clamp the circular ring 5, the clamping groove 32 on the first T-shaped plate 26 is opposite to the second T-shaped plate 30 (as shown in Figure 8 Then the second T-shaped plate 30 is loosened, and then the second T-shaped plate 30 is inserted into the clamping groove 32 under the action of the plurality of second springs 31 to limit the position of the first T-shaped plate 26, thereby ensuring the stability of the installation between the tilt sensor body 1 and the lens 3.

[0052] During the use of the tilt sensor body 1, first, the circular ring 5 is placed in the circular groove 8, then the second T-shaped plate 30 is pulled upwardly to move out of the arc-shaped slot 25, and then the first T-shaped plate 26 is rotated forwardly, so that the side wall of the first T-shaped plate 26 slides along the inner side wall of the arc-shaped slot 25, and the rotating ring 14 can be driven to rotate forwardly, at this time, under the action of the plurality of inclined grooves 15, the plurality of fixing plates 13 are driven to move close to each other through the plurality of first rods 16 and the plurality of sliding blocks 12, so that the side walls of the plurality of fixing plates 13 are attached to the inner side wall of the first annular groove 9 (as shown in Figure 4 The side walls of the plurality of fixing plates 13 are attached to the inner side wall of the first annular groove 9 (as shown in

[0053] After the plurality of fixed plates 13 clamp the ring 5, the clamping groove 32 on the first T-shaped plate 26 is opposite to the second T-shaped plate 30 (as shown in Figure 8 Then, the second T-shaped plate 30 is inserted into the clamping groove 32 under the action of the plurality of second springs 31, and the position of the first T-shaped plate 26 is limited, thereby ensuring the stability of the installation between the tilt sensor body 1 and the lens 3.

[0054] When the rotating ring 14 rotates forward, the two arc-shaped toothed plates 23 can drive the two second rods 20 to rotate forward through the two gears 24, and the two lead screws 19 are driven to rotate forward through the first bevel gear 21 and the second bevel gear 22, so that the two semicircular plates 18 are close to each other, and the inner side walls of the two semicircular plates 18 are in contact with the outer side wall of the ring 5 (it should be noted that the inner side walls of the two semicircular plates 18 are provided with sealing pads), thereby sealing the gap between the ring 5 and the circular groove 8, and avoiding impurities or rainwater from entering the installation position between the tilt sensor body 1 and the lens 3 during use.

[0055] The light cup 2 and the lens 3 are arranged, the light cup 2 can refract the light rays incident thereon and enter the lens 3, and the light rays are collimated through the emission of the side wall of the lens 3, thereby achieving the purpose of reducing the angle and increasing the central light intensity. The inner surface of the light cup 2 and the outer surface of the lens 3 are both in the shape of a rhombus, which is conducive to the light rays being refracted by the light cup 2 being more refracted onto the lens 3, so that the light rays are collimated and emitted, thereby increasing the central light intensity and increasing the detection accuracy and precision of the tilt sensor body 1, avoiding the phenomenon that the light beam angle of the LED lighting source in the prior art cannot be well controlled, thereby affecting the accuracy and precision of the tilt sensor body 1.

[0056] The frosted layer 4 is a light frosted layer, mainly playing a role of anti-glare, although this part will increase a little light transmittance, but it is not useful light, and will not affect the detection accuracy and precision of the tilt sensor body 1, avoiding the prior art of adding a light shield or a grille in front of the LED lighting source, which will reduce the light efficiency of the LED lighting source and affect the accuracy and precision of the tilt sensor body 1.

[0057] In use of the present inclination sensor body 1, when the second T-shaped plate 30 is subjected to a small upward force, the second T-shaped plate 30 moves slowly, and the sidewall of the second T-shaped plate 30 is still located in the clamping groove 32 under the action of the plurality of second springs 31, so that the inclination sensor body 1 and the lens 3 are stably installed. When the second T-shaped plate 30 is subjected to a large upward force, the force of the plurality of second springs 31 is overcome, the non-Newtonian liquid in the buffer bag 33 is subjected to a large force, and the non-Newtonian liquid is in a solid state, thereby preventing the second T-shaped plate 30 from moving upward, so as to avoid the second T-shaped plate 30 from moving out of the clamping groove 32, and to prevent the inclination sensor body 1 and the lens 3 from being unstably installed.
