[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0018] Example 1
[0019] The utility model provides a Figure 1-Figure 3 As shown, it includes: a sensor base 1, a protective cover 2 is snap-connected at one end of the sensor base 1, a positioning block 4 is fixedly installed inside the protective cover 2, connecting rods 5 are installed at both ends of the positioning block 4, a base 6 is provided on one end face of the connecting rod 5, an extrusion block 10 is slidably connected inside the base 6, a fixing belt 3 is fixedly connected on one end face of the extrusion block 10, a rotating shaft 12 is fixedly installed on the bottom surface of the inner part of the protective cover 2, and a V-shaped support frame 11 is rotatably connected to the outer side of the rotating shaft 12. The V-shaped support frame 11 is subjected to force to push the fixing belt 3 to fit with the sensor base 1, and at the same time is squeezed by the extrusion block 10 on the fixing belt 3, thereby increasing the extrusion force between the sensor base 1 and the protective cover 2, so that the connection between the sensor base 1 and the protective cover 2 is more stable.
[0020] like Figure 3 As shown, a sliding groove 8 is provided inside the positioning block 4, and a plastic block 9 is provided inside the sliding groove 8. A movable block 7 is fixed to one end face of the plastic block 9. One end face of the two fixed belts 3 is respectively fitted with one end face of the sensor base 1. A support block 13 is movably installed on one end face of the V-shaped support frame 11, and a support block 2 14 is movably installed on the other end face of the V-shaped support frame 11. When the support block 13 is subjected to force, it will push the V-shaped support frame 11 around the rotating shaft 12 to act on the support block 2 14, so that the support block 2 14 pushes the fixed belt 3 to move. In order to push the fixing belt 3 to move, the difficulty of moving the fixing belt 3 is changed. The shape of the plastic block 9 is L-shaped, and an inclination angle is provided on one end edge of the plastic block 9. The number of the plastic blocks 9 is set to two. One end of the moving block 7 is fixedly installed on one end of the sensor base 1. The moving block 7 can push the plastic block 9 to move inside the sliding groove 8 to achieve the purpose of clamping, thereby fixing the positioning block 4, thereby achieving the purpose of increasing the stability of the sensor base 1 and the protective cover 2, and preventing the problem of separation between the sensor base 1 and the protective cover 2.
[0021] Working principle: When the sensor base 1 is pushed into the protective cover 2 for connection, the support block 2 14 is pushed to make the V-shaped support frame 11 rotate around the rotating shaft 12, and the V-shaped support frame 11 rotationally pushes the support block 1 13, and makes the support block 1 13 fit with the fixing belt 3, and then the V-shaped support frame 11 is forced to continue to rotate, at this time the V-shaped support frame 11 pushes the fixing belt 3 to fit with the sensor base 1 through the support block 13, and at this time the fixing belt 3 squeezes the edge of the sensor base 1. At the same time, due to this method during operation, the moving block 7 drives the plastic block 9 to move along the inside of the sliding groove 8, and the plastic block 9 and the positioning block 4 are clamped and fixed, thereby achieving the purpose of clamping and fixing between the sensor base 1 and the protective cover 2. Through the two methods of clamping and extrusion, the stability between the sensor base 1 and the protective cover 2 is increased, and the separation between the sensor base 1 and the protective cover 2 is prevented, further achieving the purpose of protecting the chip inside the sensor base 1.
[0022] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
