[0037] To sum up, a relatively sealed device shell is formed by the detachable connection between the L-shaped bottom shell 2 and the top shell 1. The fixing component 6 is arranged on the side wall of the bottom shell 2. When the device is assembled, the plug-in block 63 is squeezed and then plugged into the top shell 1 under the action of the first elastic member 62, which can make the overall structure of the top shell 1 and the bottom shell 2 stable. When disassembling, it is only necessary to move the plug-in block 63 to separate it from the top shell 1 to unlock the connection between the top shell 1 and the bottom wall.

[0041] In the above embodiment, the unlocking hole 102 and the locking hole 103 on both sides of the adjustment hole 101 are used to respectively lock the position state of the plug-in block 63 to achieve unlocking and locking of the assembly of the top shell 1 and the bottom shell 2.

[0042] The adjusting rod 7 is a hollow structure, and a rotating rod 8 is arranged inside the rotating cavity. The rotating rod 8 can rotate in the rotating cavity or extend and retract relative to the adjusting rod 7. The adjusting rod 7 is driven by toggling the rotating rod 8 to control the opening and closing of the plug-in block 63. After reaching the appropriate position, the rotating rod 8 is slightly pulled out, and its second end is clamped in the unlocking hole 102 or the locking hole 103 to maintain the unlocked or locked state of the assembly of the top shell 1 and the bottom shell 2.

The guide protrusions 9 are slidably connected to the guide rails 10 so that the top shell 1 and the bottom shell 2 fit tightly.

[0044] In the above embodiment, the guide protrusions 9 and guide rails 10 not only ensure a tight fit between the top shell 1 and the bottom shell 2, but also enhance the stability of the overall structure. The guide protrusions 9 and guide rails 10 allow the top shell 1 and the bottom shell 2 to be assembled by pushing, maintaining accurate alignment.

[0045] In one embodiment, a transmission interface is provided at one end of the wireless communication port 4 away from the sensor plug-in block 635 , and the transmission interface is threadedly connected to the radio frequency antenna 11 .

The protective cover is typically made of corrosion-resistant and high-temperature-resistant plastic or metal to accommodate various usage scenarios.

[0048] refer to Figure 3 In one embodiment, the sensor plug-in block 635 is provided with a plurality of wiring ports 51 at one end away from the wireless communication port 4, and each wiring port 51 is provided with a clamping assembly 12; the clamping assembly 12 includes a pressing plate 121, and the pressing plate 121 is slidably connected to the wiring port 51, and a pressing rod 122 is provided at the top of the pressing plate 121, and the pressing rod 122 penetrates the sensor plug-in block 635, and the pressing rod 122 is provided with a second elastic member 123, and the two ends of the second elastic member 123 are respectively connected to the pressing plate 121 and the top wall of the wiring port 51.

[0049] In the above embodiment, the provision of the compression assembly 12 ensures stable contact pressure between the connection port 51 and the connected wire. When a wire is inserted into the connection port 51, the compression rod 122, under the action of the second elastic member 123, generates a certain amount of pressure, which ensures that the wire contacts the contact pad inside the connection port 51, thereby ensuring stable and reliable signal transmission. To remove the wire, the pressure can be released by pulling on the compression rod.

[0050] In one embodiment, a contact portion is provided at one end of the sensor plug-in block 635 facing the wireless communication port 4, and a plug-in port is provided on the circuit board 3 corresponding to the contact portion.

The contact portion comprises multiple elastic contacts to ensure close contact with the plug-in port of the circuit board 3 during insertion and removal, thereby ensuring stable and reliable signal transmission.

[0052] The plug-in port of the circuit board 3 matches the contact portion, ensuring that the contact portion is not damaged during insertion and removal. Multiple conductive springs are located within the plug-in port to ensure good contact between the contact portion and the plug-in port. A dust cover is also provided around the plug-in port of the circuit board 3 to prevent dust and debris from entering the port and affecting the normal operation of the sensor plug-in block 635.

[0053] In practical applications, the connection method between the sensor plug-in block 635 and the circuit board 3 is not limited to the above embodiment. For example, various other methods, such as snap-on connection and magnetic connection, can also be used to adapt to different usage environments and requirements.

[0054] In one embodiment, the circuit board 3 is provided with a plurality of indicator lights, the tops of the indicator lights abut against the top shell 1 , and the top shell 1 is provided with a transparent portion 104 covering the indicator lights.

[0055] In the above embodiment, the transparent portion 104 can be made of high-strength polycarbonate or acrylic to ensure sufficient impact resistance and durability. The shape of the transparent portion 104 is designed to match the contour of the top case 1, ensuring that it can fit tightly on the top case 1, thereby preventing dust and moisture from entering the circuit board 3 area.

[0056] In addition, the edge of the transparent portion 104 can be designed to have a certain degree of elasticity so that it can be easily pressed into the corresponding groove of the top case 1 during installation. To further enhance the sealing effect, the contact surface between the transparent portion 104 and the top case 1 can be coated with a thin layer of silicone gasket to ensure that it will not loosen due to vibration or temperature changes during long-term use.

[0057] The top of the indicator light is flush with the inner surface of the transparent portion 104, which avoids any protrusions on the transparent portion 104 and reduces accidental scratches on the transparent portion 104 during transportation or use. To improve the visibility of the indicator light, the thickness of the transparent portion 104 can be adjusted appropriately to ensure that light can pass through smoothly.

[0058] In one embodiment, a magnetic block is provided at one end of the guide protrusion 9 away from the wireless communication port 4, and a metal sheet corresponding to the magnetic block is provided at one end of the guide rail 10 away from the wireless communication port 4. The magnetic block and the metal sheet are attracted to each other so that the top shell 1 and the bottom shell 2 are tightly connected when they are closed.

[0059] In the above embodiment, when the top shell 1 and the bottom shell 2 are plugged in and closed, the innermost end of the bottom shell 2 abuts against the side wall of the top shell 1. The guide protrusion 9 here is provided with a magnetic block, and the guide rail 10 is correspondingly provided with a metal sheet that can be magnetically attracted, so that the top shell 1 and the bottom shell 2 are attracted to each other, thereby enhancing the stability of the connection.
