[0032] 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.

[0033] Example

[0034] Reference Figure 1-5, an embodiment provided by the present utility model: a novel inertial sensor, including a sensor body 1 and a cover 11. A cavity 3 is provided on the lower end surface of the sensor body 1. A retaining ring 5 is embedded at the midpoint inside the cavity 3. A battery slot 6 is provided inside the retaining ring 5. Arc-shaped grooves 8 are provided on both sides and the front and rear ends of the inner wall of the cavity 3. The retaining ring 5 is used to separate the battery slot 6 and the arc-shaped grooves 8 in the cavity 3, so as to facilitate the independent embedding and installation operations of different components and avoid interference between each other. Extrusion components 7 are embedded in all four arc-shaped grooves 8;

[0035] The extrusion component 7 includes two springs 701, a bottom plate 702 and a special-shaped arc panel 703. A side plate 14 is fixedly provided at the midpoint of the upper end surface of the cover 11, and a hollow layer 10 is provided inside the side plate 14. A battery 15 is embedded at the midpoint inside the hollow layer 10. The provided battery 15 can be quickly disassembled and replaced. Fixed blocks 13 are fixedly provided on both sides of the upper and lower ends of the outer wall of the side plate 14.

[0036] Specifically, according to the above embodiment, a plurality of grooves 2 are provided on the outer edge of the lower end surface of the sensor body 1, and convex blocks 12 are fixedly provided on the outer edge of the lower end surface of the cover 11. The plurality of convex blocks 12 are respectively embedded inside the plurality of grooves 2. When installing the cover 11, the corresponding property of the convex blocks 12 and the grooves 2 can be used to achieve a positioning function to a certain extent and assist in the positioning and installation of the cover 11. The upper end of the convex block 12 is a circular arc surface convex structure and is made of rubber material, so that it has a certain shrinkage and deformation effect;

[0037] Specifically, according to the above embodiment, an installation groove 9 is provided on one side of the rear end of the lower end surface of the sensor body 1, and a copper sheet 4 is fixedly provided inside the installation groove 9. The copper sheet 4 penetrates through the retaining ring 5 and is connected to the outer wall of the battery 15. The battery 15 is embedded inside the battery slot 6, and all four fixed blocks 13 are embedded inside the cavity 3.

[0038] That is, the side of the copper sheet 4 is located at the inner wall of the retaining ring 5. When the battery 15 is embedded into the battery slot 6 inside the retaining ring 5, since one end of the copper sheet 4 is a rotated C-shaped, that is, the battery 15 exerts extrusion on the copper sheet 4, and the side of the copper sheet 4 exerts extrusion on the side plate of the battery 15 due to the restoration effect, thereby forming an auxiliary clamping function to a certain extent.

[0039] Specifically, according to the above embodiment, the four fixed blocks 13 are respectively embedded in the four arc-shaped grooves 8, and the outer walls of the four fixed blocks 13 are all circular arc surface structures. The special-shaped arc panel 703 is fixedly provided on the lower end surface of the bottom plate 702, and the bottom plate 702 is fixedly provided in the arc-shaped groove 8 through two springs 701. The retaining ring 5 is embedded inside the hollow layer 10 between the side plate 14 and the battery 15.

[0040] It can be seen that the fixing block 13 is first embedded in the cavity 3, and then rotates counterclockwise to enter the arc groove 8. During the counterclockwise rotation, an extrusion thrust is generated on the upper end of the special-shaped arc panel 703 to make it move upward. The upward movement of the special-shaped arc panel 703 generates a thrust on the bottom plate 702 and the spring 701. The spring 701 is forced to shrink and generate a restoring thrust, thereby driving the bottom plate 702 and the special-shaped arc panel 703 to generate an extrusion force on the fixing block 13, so that it can be clamped and fixed. At the same time, the copper sheet 4 set up starts a certain restriction effect, so that it can only rotate counterclockwise to complete the auxiliary clamping and fixing effect.

[0041] Working principle: When in use, the cover 11 with the battery 15 can be embedded into the lower end of the sensor body 1, and the convex block 12 on the upper end of the cover 11 and the groove 2 on the sensor body 1 are used for auxiliary positioning and connection. After the battery 15 is embedded in the battery slot 6 and the fixing block 13 is embedded in the cavity 3, the cover 11 is rotated counterclockwise so that the fixing block 13 rotates into the arc groove 8 and is assisted in extrusion and clamping by the extrusion component 7. At the same time, during the rotation process, the arc-shaped convex block 12 at the upper end is embedded in the corresponding groove 2 as the rotation is adjusted to achieve the final combined installation.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
