[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-7 The utility model provides a technical solution: an anti-disassembly verification sensor device, including a bottom shell 1, the top of the bottom shell 1 is connected to a top shell 2, the top and ends of the bottom shell 1 are open, and the top shell 2 is an L-shaped structure as a whole. The tops of the two corresponding inner walls of the bottom shell 1 are provided with horizontal connecting card grooves 3, and the two ends of the bottom of the top shell 2 are symmetrically provided with steps 4, and the steps 4 are slidably connected to the inside of the connecting card grooves 3. The ends of the bottom shell 1 are symmetrically and integrally connected with connecting rods 5, and the bottom of the top shell 2 is symmetrically provided with connecting holes 6, and the connecting rods 5 are clamped inside the connecting holes 6.

[0025] It should be noted that when the utility model connects the top shell 2 and the bottom shell 1, the two steps 4 at the bottom of the top shell 2 are connected to the corresponding connecting slots 3 at the top ends of the two inner walls of the bottom shell 1, so that the steps 4 are slidably inserted into the connecting slots 3. During the insertion process, the two connecting rods 5 at one end of the top shell 2 at the bottom of the bottom shell 1 are inserted into the connecting holes 6 on the top shell 2, and at the same time, the plugging plate 7 on the bottom shell 1 is correspondingly inserted into the slot 8 on the top shell 2. After the plugging plate 7 is completely inserted into the card hole 9, the bottom of the plugging plate 7 passes through the top of the elastic card rod 10, so that the elastic card rod 10 is elastically clamped into the card hole 9 on the plugging plate 7, so that the two are locked and connected. At the same time, during the connection process, the elastic block 11 at the top end of the inner wall of the bottom shell 1 passes through the bottom of the protrusion 13. After the end of the elastic block 11 is tightly pressed against the inner wall of the protrusion 12, the elastic block 11 is reset under the elastic action, so that the protrusion 13 is clamped into the positioning groove 14, so that the bottom shell 1 and the top shell 2 are locked and connected.

[0026] The bottom of the inner wall of the bottom shell 1 is symmetrically fixedly connected with an inserting plate 7 between two connecting rods 5 , and the end of the top shell 2 is symmetrically provided with a slot 8 , and the inserting plate 7 is slidably inserted into the slot 8 .

[0027] It should be noted that when the top shell 2 is connected to the bottom shell 1, the step 4 on the top shell 2 is slidably inserted into the connecting slot 3 on the bottom shell 1. During the connection process between the two, the plug-in plate 7 on the bottom shell 1 is inserted into the slot 8 on the top shell 2 to ensure a firm connection between the two.

[0028] The end of the plug board 7 is provided with an inclined surface, the bottom of the inner wall of the top shell 2 is symmetrically fixedly connected with an elastic clamping rod 10, and the top of the elastic clamping rod 10 is provided with an inclined surface, and the top of the plug board 7 is provided with a clamping hole 9, and the elastic clamping rod 10 is clamped in the clamping hole 9.

[0029] It should be noted that when the plug-in board 7 on the bottom shell 1 is inserted into the slot 8 on the top shell 2, the inclined surface at the end of the plug-in board 7 squeezes the inclined surface on the elastic clamping rod 10, so that the plug-in board 7 passes through the top of the elastic clamping rod 10. After the bottom shell 1 and the top shell 2 are connected, the elastic clamping rod 10 is located below the clamping hole 9 on the plug-in board 7. At this time, the elastic clamping rod 10 is reset under the action of elasticity, so that it is quickly clamped into the clamping hole 9 on the plug-in board 7, thereby locking and fixing the bottom shell 1 and the top shell 2.

[0030] The top of the inner wall of the top shell 2 is located between the two steps 4 and is integrally connected with a convex plate 12, the top of the inner wall of the bottom shell 1 is fixedly connected with an elastic block 11, and the end of the elastic block 11 is provided with a slope, the bottom of the convex plate 12 is integrally connected with a protrusion 13, and the end of the protrusion 13 located outside the top shell 2 is provided with a slope, the slope of the end of the protrusion 13 cooperates with the slope of the end of the elastic block 11, and a positioning groove 14 is opened at the top of the elastic block 11, and the protrusion 13 is snapped into the inside of the positioning groove 14.

[0031] It should be noted that, when the top shell 2 and the bottom shell 1 are connected, the elastic block 11 at the top of the inner wall of the bottom shell 1 passes through the bottom of the protrusion 13. After the end of the elastic block 11 is pressed against the inner wall of the protruding plate 12, the elastic block 11 is reset under the elastic action, so that the protrusion 13 is stuck into the positioning groove 14, thereby locking the connection between the bottom shell 1 and the top shell 2.

[0032] The convex plate 12 is in an L-shaped structure as a whole, and the end of the elastic block 11 contacts the inner wall of the convex plate 12 .

[0033] It should be noted that the protruding plate 12 is arranged to be an L-shaped structure, so that after the elastic block 11 is connected to the protruding plate 12, the L-shaped end of the protruding plate 12 can block the elastic block 11, so that the elastic block 11 is reset in the protruding plate 12, so that the protruding block 13 is located at the upper part of the positioning groove 14 on the elastic block 11, so that the protruding block 13 is quickly stuck in the positioning groove 14.

[0034] The top and the end of the bottom shell 1 are fixedly connected with a sealing gasket, and the sealing gasket is in contact with the bottom of the top shell 2.

[0035] It should be noted that by providing a sealing gasket at the opening edge of the bottom shell 1, after the top shell 2 is connected to the bottom shell 1, the sealing gasket on the bottom shell 1 fits tightly with the bottom of the top shell 2, so that the connection between the bottom shell 1 and the top shell 2 can be sealed, and the interior of the shell can be better waterproof and moisture-proof.

[0036] A control panel is installed at the bottom of the inner wall of the bottom shell 1, and sensors and alarms are installed on the surface of the control panel.

[0037] It should be noted that the device has one or more built-in sensors for detecting the status of the device or environmental conditions. The sensors may be accelerometers, Hall sensors, temperature sensors, etc., which can be selected as needed. When the sensor detects that the status of the device has changed, such as being disassembled or moved, the device will record the time of occurrence of the event and related information. The recorded data is usually stored in the internal memory or external server for subsequent inspection and analysis. Once the sensor detects an abnormal situation, the device will trigger an alarm mechanism to notify the relevant monitoring system or operator, so that the safety risks of the equipment can be discovered in time and necessary measures can be taken to deal with it.
