Abstract
The utility model relates to a kind of sensors with rotation-preventing mechanism, including sensor outer housing and lower casing, the lower casing upper end opens up connecting cavity, and lower casing also opens up the through-hole being connected to connecting cavity, the sensor outer housing lower end is connected in connecting cavity, the sensor outer housing bottom opens up mounting groove, the sensor of detection is mounted in mounting groove, sealing ring is set between connecting cavity inner plane on the downside of the sensor outer housing, the sealing ring is located at the upper of the position below sensor, convex portion is arranged in lower part, the sensor with rotation-preventing mechanism, it can prevent the sensor degradation as caused by the relative rotation of sensor outer housing and lower casing, prolong the service life, and assembly is laborsaving.
Description
Technical field
The utility model relates to sensor more particularly to a kind of sensors with rotation-preventing mechanism.
Background technique
Sensor is connected between sensor outer housing and lower casing, and there may be rotations for sensor outer housing and lower casing, is made
It is worn at sensor, service life is short, and O-ring (as shown in Figure 1) is arranged between traditional sensor outer housing and lower casing, has
Part prevents the function of rotation, but anti-rotation effect is unobvious, and there are also sensor devices between sensor outer housing and lower casing
It is arranged plain cushion (as shown in Figure 2), plain cushion is compressed by sensor outer housing and lower casing, plain cushion is deformed, can not only play sealing
Effect also generates larger frictional force, playing prevents outside sensor to the reaction force of sensor outer housing and lower casing by plain cushion
Shell and lower casing rotation, but still it is larger in the presence of assembly force needed for compression plain cushion, it assembles more difficult.
Utility model content
The applicant is directed to disadvantage mentioned above, has carried out Improvement, provides a kind of sensor with rotation-preventing mechanism.
Technical solution used by the utility model is as follows:
A kind of sensor with rotation-preventing mechanism, including sensor outer housing and lower casing, the lower casing upper end open up company
Chamber is connect, and lower casing also opens up the through-hole being connected to connecting cavity, the sensor outer housing lower end is detained and is connected in connecting cavity, institute
State sensor outer housing bottom and open up mounting groove, the sensor of detection is mounted in mounting groove, on the downside of the sensor outer housing with
Sealing ring is set between connecting cavity inner plane, and the sealing ring is located at the upper and lower part setting lug boss of the position below sensor
Point.
As a further improvement of the above technical scheme:
The sealing ring and convex portion are made into integration by rubber material.
The convex portion section is triangle.
The beneficial effects of the utility model are as follows: the sensor with rotation-preventing mechanism, by the sensor of two sides outside
The convex portion of shell and sensor cooperation lower casing compression seal ring makes convex portion that shape occur and changes, sealing can be realized
With anti-rotation dual function, and smaller assembly force is only needed, i.e. the convex portion of compressible seal ring, realize assembly, assemble laborsaving, prevented
Rotation stop is dynamic, reduces abrasion, extends the service life of sensor.

Specific embodiment
With reference to the accompanying drawing, illustrate the specific embodiment of the present embodiment
As shown in Figure 3, Figure 4, the sensor with rotation-preventing mechanism of the present embodiment, including sensor outer housing 1 and lower casing
2,2 upper end of lower casing opens up connecting cavity 21, and lower casing 2 also opens up the through-hole 22 being connected to connecting cavity 21, under sensor outer housing 1
End is detained and is connected in connecting cavity 21, and 1 bottom of sensor outer housing opens up mounting groove 11, and the sensor 3 of detection is mounted on installation
In slot 11, sealing ring 4 is set, sealing ring 4 is located at 3 lower section of sensor between 1 downside of sensor outer housing and 21 inner plane of connecting cavity
The upper and lower part of position convex portion 41 is set, 41 section of convex portion is triangle, and sealing ring 4 and convex portion 41 are by rubber
Glue material is made into integration.
When the sensor installation with rotation-preventing mechanism, sealing ring 4 is placed into lower plane in 2 connecting cavity 21 of lower casing
On, then sensor 3 is installed in the mounting groove 11 of sensor outer housing 1, is then pressed into 1 lower end of sensor outer housing lower outer
In the connecting cavity 21 of shell 2,2 compression seal ring 4 of lower casing and convex portion 41 are cooperated by sensor outer housing 1 and sensor 3, made
Deformation occurs for sealing ring 4 and convex portion 41, and two functions of sealing and anti-rotation can be realized.
Above description is the explanation to the utility model, is not the restriction to utility model, defined by the utility model
Range is referring to claim, and without prejudice to the basic structure of the utility model, the utility model can make any shape
The modification of formula.
