As an improvement, the shield is the rubber cover that longitudinal section is in U-shape, the upper end of shield forms the bottom with scale plate
The flange for the annular that portion offsets, an annular collar are arranged in the lower section of flange, shield are fixed on scale plate by connector
Bottom.
Further, several mounting holes are offered on the flange, the bottom of scale plate and annular collar are equipped with corresponding
Through-hole, connector are screw, and shield is fixed on scale board bottom portion by screw.
Further, the bottom of the sensor is shaped to inner concave arc surface, and the middle part of inner concave arc surface is equipped with positioning convex platform, corresponding
Ground, the upper surface of pedestal are upward convex cambered surface, are equipped with the location indentations matched with positioning convex platform in the middle part of the upper surface of pedestal.
Further, the positioning convex platform uses partial sphere structure, and the bottom surface of location indentations is usually to use radius bigger
Spherical surface.
Further, the inside bottom of the shield forms the groove to match with the bottom of pedestal, pedestal it is upper
End is supported on the lower section of sensor by the cooperation of location indentations and positioning convex platform, and the groove of shield is arranged in the lower end of pedestal
Middle positioning.
Finally, the bottom of the scale plate is equipped with the cavity of the top merging for sensor, sensor is fixed by screws in
Scale board bottom portion.
Compared with the prior art, the advantages of the utility model are: shield is set below scale plate, it will by shield
Sensor, pedestal sealing cladding are got up, and effectively rainwater and other corrosive substances are isolated with sensor.This is practical new
Type is simple and reasonable, easy for installation, and sensor can be prevented soaked and damaged and corrosive substance is attached to sensing
Device surface and make sensor corrosion and damage, effectively increase the protective performance of sensor, extend the service life of sensor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that axis traditional before improving retransmits sensor;
Fig. 2 is the structural schematic diagram of the utility model embodiment;
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
As shown in Fig. 2, a kind of all-sealed axis retransmits sensor, including sensor 1, scale plate 2, pedestal 3 and shield 4, pass
Sensor 1 be arranged on the base 3, be mounted on the lower section of scale plate 2, shield 4, which is sealed and coated on outside pedestal 3 and sensor 1, is fixed on scale
The bottom of plate 2;Shield 4 is the rubber cover that is in U-shape of longitudinal section, and the upper end of shield 4 is formed to offset with the bottom of scale plate 2
