DETAILED DESCRIPTION

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0025] like Figure 1-Figure 6 As shown, the waterproof housing of the sensor provided in this embodiment includes a bottom shell 1 and a top plate 6 arranged on the top of the bottom shell 1. The bottom of the bottom shell 1 is fixedly installed with an anti-slip foot pad, and the foot pad can make the housing more stable when placed. Both ends of the bottom shell 1 are fixedly installed with a first threaded tube 4, and the internal elastic connection of the bottom shell 1 is provided with a limiting belt 9. When the sensor is clamped, the limiting belt 9 can be deformed through the limiting belt 9 to clamp and protect the sensor in all directions. Both ends of the top plate 6 are fixedly installed with a second threaded tube 5, and the first threaded tube 4 and the second threaded tube 5 are both semicircular. The first threaded tube 4 and the second threaded tube 5 can form a completed threaded tube after being combined, and a sealing ring is provided between the first threaded tube 4 and the second threaded tube 5 to increase the sealing effect, and the tightness of the connection between the first threaded tube 4 and the second threaded tube 5 can be increased by the pressing sleeve 3, and the first threaded tube 4 and the second threaded tube 5 are fixedly connected by the pressing sleeve 3.

[0026] In this embodiment, if Figure 2 As shown, inside the bottom shell 1, the limiting belt 9 is elastically connected to the inner wall of the bottom shell 1 through the spring 8. The spring 8 can increase the clamping effect of the sensor, making it more convenient to clamp the sensor by driving the limiting belt 9 through the spring, and the limiting belt 9 can also ensure that the surface of the sensor will not be damaged when clamping the sensor.

[0027] In this embodiment, if Figure 1 and Figure 3 As shown, a plurality of limit columns 10 are provided at the bottom of the top plate 6, a sealing wing plate 7 is fixedly installed at the edge of the bottom of the top plate 6, and a plurality of reinforcement plates 2 are fixedly installed at the bottom of the sealing wing plate 7. The top plate 6 can be fixed to the bottom shell 1 through the reinforcement plate 2, which can effectively increase the stability when the top plate 6 is connected to the bottom shell 1, and the reinforcement plate 2 is fixedly connected to the bottom shell 1 by screws, so disassembly is also more convenient.

[0028] In this embodiment, if Figure 6 As shown, the limiting column 10 includes a sleeve column 15 fixed at the bottom of the top plate 6, the internal thread of the sleeve column 15 is connected with a threaded column 16, the bottom of the threaded column 16 is fixedly installed with a pressure plate 14, and the bottom of the pressure plate 14 is bonded with a pressure pad 17. By rotating the pressure plate 14, the threaded column 16 can be rotated and extended, and the overall length of the limiting column 10 can be extended, so that the sensor inside the bottom shell 1 can be fixed more conveniently and stably, and it is convenient to adjust and adapt to sensors of different sizes. By setting the pressure pad 17, it can prevent sliding with the surface of the sensor during clamping, and at the same time, the surface of the sensor can be protected.

[0029] In this embodiment, if Figure 4 and Figure 5As shown, a sealing gasket 11 is movably installed inside the pressing sleeve 3, and the connecting line of the sensor can be inserted through the pressing sleeve 3. When the pressing sleeve 3 is rotated, the sealing gasket 11 can be squeezed by the first threaded tube 4 and the second threaded tube 5, so that the sealing gasket 11 is inserted into the gap between the pressing sleeve 3 and the connecting line, thereby effectively improving the sealing performance. A plurality of elastic sealing strips 12 are provided on the sealing gasket 11, and the elastic sealing strips 12 can be deformed when squeezed to adapt to the contact port between the pressing sleeve 3 and the connecting line. A rubber pad 13 is fixedly installed on the inner side of one end of the sealing strip 12, which increases the tightness during connection, improves the sealing effect, effectively isolates it from the outside world, and has high waterproof performance.

[0030] In this embodiment, if Figure 1-Figure 6 As shown, the working process of the sensor waterproof housing provided in this embodiment is as follows:

[0031] Step 1: When in use, the sensor is placed inside the bottom shell 1, and the sensor can be fixed by the limiting belt 9 and the spring 8. The limiting belt 9 deforms to adapt to the shape of the sensor to fix the sensor, and the connecting line is placed on the first threaded tube 4;

[0032] Step 2: Then snap the top plate 6 into the bottom shell 1, and combine the second threaded tube 5 with the first threaded tube 4. By adjusting the length of the limit column 10 and pressing the sensor, the stability of the sensor is increased, and then it is fixed to the bottom shell 1 through the reinforcement plate 2. After the fixation is completed, the first threaded tube 4 is threadedly connected to the first threaded tube 4 and the second threaded tube 5, and the pressing sleeve 3 is gradually twisted to squeeze the sealing gasket 11 through the first threaded tube 4 and the second threaded tube 5.

[0033] In summary, in the present embodiment, according to the waterproof housing of the sensor of the present embodiment, the present device has good sealing performance and can greatly increase the waterproof performance. At the same time, a sealing ring is provided between the first threaded tube 4 and the second threaded tube 5 to increase the sealing effect, and the pressure sleeve 3 can increase the tightness of the connection between the first threaded tube 4 and the second threaded tube 5. The spring 8 can increase the clamping effect of the sensor, and it is more convenient to clamp the sensor by driving the limit belt 9 through the spring, and the limit belt 9 can also ensure that the surface of the sensor will not be damaged when the sensor is clamped. The top plate 6 can be fixed on the bottom shell 1 through the reinforcement plate 2, which can effectively increase the stability of the top plate 6 when connected to the bottom shell 1, and the reinforcement plate 2 is fixedly connected to the bottom shell 1 by screws, and disassembly is also more convenient. By rotating the pressure plate 14, the threaded column 16 can be rotated and extended, and the overall length of the limit column 10 can be extended, which is more convenient and stable to fix the sensor inside the bottom shell 1, and is convenient to adjust to adapt to sensors of different sizes. By setting the pressure pad 17, it can prevent sliding with the surface of the sensor during the clamping process, and at the same time, the surface of the sensor can be protected.
