Description

Technical Field

[0001] The utility model relates to the technical field of inclination sensors, and particularly relates to a portable inclination sensor. Background Art

[0002] An inclination sensor is a device based on micro-electro-mechanical system technology that can sense the acceleration of gravity and the acceleration change of an object relative to the vertical direction. Through a series of calculations and processes, it can obtain the inclination angle information of the carrier. Inclination measurement is one of the essential physical quantities in fields such as civil engineering, aerospace, industrial automation, and automotive navigation.

[0003] For example, the patent application with the application number CN201922301064.6 includes a bottom plate, a sensor body, and a cover. The top of the bottom plate is fixedly connected to the bottom of the sensor body by soldering, and the top of the sensor body is fixedly connected to the bottom of the cover by screws. Inside the bottom plate and on both sides of the sensor body, there are sliding grooves. The top of the cover is provided with a protective shell, and on both sides of the bottom of the protective shell, there are fixed pulleys. The surface of the pulley is slidably connected to the inner wall of the sliding groove. The utility model relates to the technical field of inclination sensors. This portable inclination sensor can facilitate the user to carry the sensor, and can provide good protection for the sensor during carrying, preventing moisture or dust from entering the interior of the sensor through the plug, and can also prevent damage caused by the sensor being squeezed, reducing the loss of the user, being convenient and fast, with high safety, and facilitating the user to operate.

[0004] However, when the above-mentioned inclination sensor is in use, the protective shell is pulled out from the top of the bottom plate along the sliding groove inside the bottom plate. If the gap between the sliding groove and the protective shell is small, the frictional force between them is large, resulting in the protective shell being difficult to remove from the bottom plate, thus reducing the disassembly and assembly efficiency of the inclination sensor. If the gap between the sliding groove and the protective shell is large, the sealing performance between the protective shell and the bottom plate is reduced, thus reducing the sealing effect of the inclination sensor. There is an urgent need to design a portable inclination sensor to solve the above problems. Summary of the Utility Model
