Description

Technical Field

[0001] The utility model relates to the field of waterproofing of angle sensors, and particularly to an angle sensor. Background Art

[0002] An angle sensor is a device used to measure the rotation angle of an object. It can convert the change in angle into an electrical signal or other forms of output for applications such as measurement, control, and monitoring. Angle sensors are widely used in modern geography, civil applications, mechanical products, and some measuring tools, including electronic compasses and gyroscopes for measuring azimuth, satellite GPS systems, experimental instruments, digital levels, inertial navigation systems, human posture measurement in industrial machinery, motorcycle gyroscopes, optical fibers, guidance, and many other aspects.

[0003] Existing angle sensors are diverse, but there are still certain problems: Most existing angle sensors do not have waterproof properties, so when the machinery and instruments they are used in are installed and used in actual situations, in the face of humid environments such as rivers, wetlands, and rainforests, water vapor is likely to seep in, leading to rust on the sensor housing and malfunction of parts, causing difficulties in the use of the angle sensor. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the shortcoming that most existing angle sensors do not have waterproof properties in the prior art, and to propose an angle sensor.

[0005] To solve the problems existing in the prior art, the present utility model adopts the following technical solutions:

[0006] An angle sensor includes a cylinder, a sensor body is provided inside the cylinder, a rotating shaft is fixedly provided at the lower end of the sensor body, the rotating shaft penetrates through the cylinder, and a waterproof mechanism is provided inside the cylinder.

[0007] Preferably, the waterproof mechanism includes a fixing frame, the fixing frame is fixedly connected to the inner wall of the cylinder, a plurality of fixing grooves are formed on the fixing frame, an elastic filter plate is clamped between the plurality of fixing grooves, a plurality of chambers are formed between the fixing frame and the inner wall of the cylinder, and drying packets are placed in each chamber.

[0008] Preferably, a threaded groove is formed on the inner wall of the upper end of the cylinder, a cover plate is threadedly connected to the upper end of the cylinder, and an internal hexagonal groove is formed on the upper surface of the cover plate.

[0009] Preferably, a flange is fixedly provided at the upper end of the cylinder, and a rubber ring is provided on the upper surface of the flange.

[0010] Preferably, a plurality of bolts are inserted into the flange, and washers are sleeved on the bolts.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, the drying packet is placed in the chamber, the elastic filter plate is successively snapped into the fixing groove, and the sensor body is placed in the cylinder. The drying packet absorbs the water vapor seeping into the cylinder. Even when the manufactured machinery and instruments are faced with humid environments such as rivers, wetlands, and rainforests, there will be no rusting of the sensor and malfunction of parts caused by water vapor seepage. When regularly inspecting the inside of the cylinder, the elastic filter plate can be directly removed from between the fixing grooves, and the drying packet can be replaced very conveniently, always maintaining the dryness inside the cylinder, greatly increasing the service life of the device;

[0013] 2. In the present utility model, the cylinder is fixed to the area to be installed by bolts. When the mechanical equipment is running, it often vibrates. In a dynamic or vibrating environment, the gasket can absorb part of the vibration and impact, reduce the influence on the connection, and at the same time can isolate the direct contact between the bolt and the connection, thereby preventing corrosion to a certain extent. When the rubber ring is fixed, it will be extruded and deformed to seal the flange, and at the same time reduce the influence of vibration on the service life of the device.
