[0015] 1. The sealing cover and the protective tube are installed by means of spring compression adjustment through the provided fixing ring and the mounting ring. The No. 2 return spring is compressed and adjusted by the limiting rod being squeezed by the fixing ring.

[0028] There are two fixing rings 6, and a mounting ring 15 is slidably connected between the two fixing rings 6, and the outer wall of the mounting ring 15 matches the shape and size of the inner wall between the two fixing rings 6;

[0029] The inner wall of the fixing ring 6 is movably connected with a limit rod 18, and the limit rod 18 forms a telescopic structure through a No. 2 return spring 17, and the outer wall of the limit rod 18 is engaged with a card slot 7;

[0030] There are eight No. 2 return springs 17 , and every two No. 2 return springs 17 form a group. Four groups of No. 2 return springs 17 are installed at equal distances in the No. 2 adjustment grooves 16 that penetrate the outer wall of the mounting ring 15 .

[0031] The specific implementation method is as follows: by setting the fixing ring 6 and the mounting ring 15, the sealing cover 13 and the protection tube 3 are installed by means of spring compression adjustment, and the No. 2 return spring 17 is compressed and adjusted by the limiting rod 18 being squeezed by the fixing ring 6. At this time, the sealing cover 13 is rotated so that the sealing cover 13 drives the mounting ring 15 and the limiting rod 18 to rotate, thereby driving the limiting rod 18 to slide along the fixing ring 6 to the slot 7, and then the limiting rod 18 and the No. 2 return spring 17 are compressed and disappear. At this time, the No. 2 return spring 17 recovers its deformation, so that the No. 2 return spring 17 drives the limiting rod 18 and the slot 7 to be installed;

[0032] Thereby, it is convenient for the staff to quickly disassemble and assemble the magnetic sensor detection device for the underground parking space vehicle, thereby improving the efficiency of the staff in subsequent battery replacement of the magnetic sensor detection device for the underground parking space vehicle, ensuring the stability of the subsequent use of the magnetic sensor detection device for the underground parking space vehicle, and increasing the practicality of the overall device.

[0033] See also Figure 1-6 The utility model provides a technical solution: a magnetic sensor detection device for underground parking spaces for vehicles, the top of a No. 1 reset spring 9 is fixedly connected with an adjusting plate 10, and a sealing ring 11 is arranged on the top of the adjusting plate 10, a mounting plate 12 is installed on the outer wall of the protection tube 3, and a sealing cover 13 is installed on the top of the protection tube 3, a mounting ring 15 is fixedly connected to the bottom end of the sealing cover 13, and a No. 2 adjusting groove 16 is penetrated through the outer wall of the mounting ring 15, a No. 2 reset spring 17 is fixedly connected to the inner wall of the No. 2 adjusting groove 16, the other end of the No. 2 reset spring 17 is fixedly connected to a limiting rod 18, the outer wall of the sealing cover 13 is fixedly connected with a bearing frame 19, and the inner wall bearing of the bearing frame 19 is connected with an adjusting clamping rod 20.

[0034] An extrusion groove 14 is formed at the bottom end of the sealing cover 13, and a sealing ring 11 is movably connected to the inner wall of the extrusion groove 14, and the sealing ring 11 forms an extrusion structure through the extrusion groove 14;

[0035] The sealing ring 11 forms a compression structure with the No. 1 return spring 9 through the adjustment plate 10, and there are eight No. 1 return springs 9, which are fixedly connected to the bottom end of the adjustment plate 10 at equal distances;

[0036] The outer wall of the adjusting clamp rod 20 is movably connected with the mounting plate 12 , and the adjusting clamp rod 20 forms an extrusion adjustment structure through the mounting plate 12 , and the sealing cover 13 forms a mounting structure with the protective tube 3 through the adjusting clamp rod 20 .

[0037] The specific implementation method is as follows: by setting a No. 1 return spring 9, a mounting plate 12 and a bearing frame 19, the sealing connection between the protection tube 3 and the sealing cover 13 is completed by adopting a method of extrusion installation and spring deformation, and the bearing frame 19 is driven by the sealing cover 13 to be extruded and adjusted through the mounting plate 12. At this time, the sealing cover 13 is installed through the mounting plate 12 fixed to the outer wall of the bearing frame 19 and the protection tube 3, so that the sealing cover 13 compresses and adjusts the No. 1 return spring 9 through the sealing ring 11 and the adjusting plate 10. Since the thickness of the sealing ring 11 changes due to long-term wear of the sealing ring 11, at this time, the No. 1 return spring 9 recovers its deformation and drives the sealing ring 11 and the sealing cover 13 to be sealed again through the adjusting plate 10;

[0038] The problem that the sealing effect of the existing underground parking vehicle magnetic sensor detection device is reduced after long-term use is solved, thereby facilitating automatic adjustment of the overall device after long-term use, thereby improving the sealing between the protection tube 3 and the sealing cover 13, and preventing subsequent ground water flow from entering the protection tube 3, thereby ensuring the stability of the overall device during use.

[0039] Working principle: When using the magnetic sensor detection device for underground parking spaces, first install the magnetic sensor detector housing 1 with the hole punched in the ground, increase the force-bearing area of ​​the reinforcement ribs 2 and the cement through the multiple reinforcement ribs 2 arranged on the outer wall of the magnetic sensor detector housing 1, and then connect it with the ground surface through the shield 4 to complete the installation of the magnetic sensor detector housing 1 and the ground. When the staff needs to replace the battery of the magnetic sensor detection device for underground parking spaces;

[0040] At this time, the adjusting clamping rod 20 is first pulled to make the adjusting clamping rod 20 rotate along the bearing frame 19, thereby driving the adjusting clamping rod 20 and the mounting plate 12 to fall off through the bearing frame 19, and then by rotating the sealing cover 13, the sealing cover 13 drives the mounting ring 15 to rotate, so that the mounting ring 15 rotates along the inner wall of the fixing ring 6, thereby driving the limiting rod 18 and the clamping groove 7 that penetrates the inner wall of the fixing ring 6 to fall off, and then the limiting rod 18 is squeezed by the inner walls of the two fixing rings 6;

[0041] At this time, the limiting rod 18 is compressed into the No. 2 adjustment groove 16 that penetrates the outer wall of the mounting ring 15 by the No. 2 reset spring 17, and then the sealing cover 13 is pulled to make the mounting ring 15 and the fixing ring 6 fall off, completing the disassembly of the sealing cover 13, which is convenient for the staff to disassemble and assemble the internal battery of the magnetic sensor detection electronic component 5 later. Similarly, the sealing cover 13 drives the mounting ring 15 and the fixing ring 6 to engage with each other, completing the installation of the sealing cover 13 and the protective tube 3, and at the same time, the extrusion groove 14 at the bottom end of the sealing cover 13 squeezes the sealing ring 11;

[0042] At this time, the sealing ring 11 is subjected to force to compress and adjust the adjustment plate 10 and the No. 1 return spring 9, so that the No. 1 return spring 9 is adjusted along the No. 1 adjustment groove 8 opened on the top of the protective tube 3. When the sealing ring 11 has been worn for a long time, the pressure on the sealing ring 11 is reduced, so that the No. 1 return spring 9 can restore its deformation, thereby driving the adjustment plate 10 and the sealing ring 11 to extrude the extrusion groove 14 for the second time through the No. 1 return spring 9, thereby ensuring the sealing between the extrusion groove 14 and the protective tube 3.

[0043] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
