The two third sliders 642 are respectively fixedly connected to the upper and lower side ends of the second slider 641, and the two third sliders 642 are used to slide with the two limiting grooves to limit the movement of the second slider 641. The second slider 641 is provided with a plurality of third sliders 642, and the second slider 641 is provided with a plurality of third sliders 642. Fig.11 At least one spring slot 6411 is provided in the vertical direction shown in the figure. Each spring slot 6411 is opened at the side end of the second slider 641 to accommodate a spring 643. The spring 643 corresponds to the spring slot 6411 and is inserted into the spring slot 6411 to buffer the impact generated during the movement of the second slider 641.

[0052] In this embodiment, Fig. 9 In the process, the push rod 624 pushes the second slider 641 to the left to slide to the left, driving the two locking mechanisms 5 to move to the left. During the sliding process of the second slider 641, the sliding cooperation between the two third sliders 642 and the two limiting grooves limits the second slider 641, and the self-locking fixation of the flip cover 4 is released by eliminating the squeezing and fixing of the two locking mechanisms 5 on the flip cover 4; the push rod 624 drives the second slider 641 to move to the right, and the second slider 641 drives the two locking mechanisms 5 to insert into the two plug-in grooves 76, and the flip cover 4 is squeezed, fixed and locked by the two locking mechanisms 5 to complete the shielding of the camera 3. By controlling the positional relationship of the two locking mechanisms 5, the flip cover 4 can be fixedly locked or released from self-locking, preventing the gap formed between the flip cover 4 and the second accommodating groove 73 from providing an opportunity for thieves to damage the camera 3.

[0053] like Figure 6 ,like Figure 10 to Figure 11 As shown, each group of toggle components 65 includes: a push block 651, a transfer block 652 and an arc-shaped push rod 653; wherein the push block 651 is arranged on the push rod 624 of the telescopic component 62; the transfer block 652 is arranged on the flip cover 4; one end of the arc-shaped push rod 653 is rotatably connected to the push block 651, and the other end of the arc-shaped push rod 653 is rotatably connected to the transfer block 652, which is used to push the transfer block 652 to move under the action of the push block 651, so as to drive the flip cover 4 to rotate.

[0054] Specifically, the push block 651 can be fixedly connected to the side end of the push rod 624 (such as Figure 6 The push block 651 can slide in the fixed block 621 with the push rod 624, that is, it slides with the fixed block 621 to limit the horizontal movement of the push rod 624 to reduce the vibration of the push rod 624 and also play a connecting role; the adapter block 652 is fixedly connected to the inner surface of the flip cover 4, that is, on the rear side wall facing the inside of the box body 1, to rotatably connect the two arc-shaped push rods 653; one end of the arc-shaped push rod 653 is rotatably connected to the side end of the push block 651, and the other end of the arc-shaped push rod 653 is rotatably connected to the adapter block 652. In this embodiment, the two arc-shaped push rods 653 are respectively rotatably connected to the ends of the two push blocks 651 that are away from each other, and the two arc-shaped push rods 653 slide with the two arc-shaped slide grooves 77, as shown in FIG. Figure 7 As shown, in the process of pushing the push rod 624 to the right, the two push blocks 651 move to the right, and the two push blocks 651 drive the two arc-shaped push rods 653 to slide outward in the two plug-in slots 76. The two arc-shaped push rods 653 are restricted from sliding by the two plug-in slots 76. When the first slider 623 moves to the rightmost side, the three-phase asynchronous motor is turned off. The two arc-shaped push rods 653 push the two adapter blocks 652, so that the flip cover 4 is turned outward around the hinge axis, thereby completing the removal of the obstruction of the camera 3. The first slider 623 drives the push rod 624 to move to the left. During the movement of the push rod 624, the two push blocks 651 are driven to move. The movement of the two push blocks 651 drives the arc-shaped push rod 653 to retract. The retraction of the two arc-shaped push rods 653 resets the flip cover 4. The two arc-shaped push rods 653 flip the flip cover 4. The flip cover 4 seals the second accommodating groove 73, so that passers-by at a distance are unaware of the existence of the camera 3, thereby protecting the camera 3 from being damaged by thieves.

[0055] In this embodiment, in order to avoid interference between closing of the flip cover 4 and locking of the locking mechanism 5 caused by the synchronous movement of the sliding assembly 64 and the toggle assembly 65, preferably, an elastic gasket is provided in the second receiving groove 73 so that the flip cover 4 can elastically squeeze it.

[0056] In this embodiment, the IC card plug-in block 79, the infrared sensor 100, the three-phase asynchronous motor and the vibration-sensing buzzer alarm 200 are all electrically connected to the controller 400 to form an internal circuit, which facilitates and quickly operates the system.

[0057] The following combination Figures 1 to 11 , the working principle of the device is explained in detail.

[0058] Triggering power on: When a person approaches, the infrared sensor 100 detects that the person is 5 meters away from the device, and transmits the information of the person approaching to the controller 400, and the controller 400 is started, so as to trigger the controller 400 to be powered on;

[0059] Release the self-locking: When the infrared sensor 100 monitors a person approaching the device by 2 meters, the controller 400 starts the driving assembly 51, and the driving assembly 51 drives the driving gear 631 to rotate. Through the meshing between the driving gear 631 and the driven gear 632, the driving gear 631 drives the driven gear 632 to rotate forward, and the driven gear 632 drives the screw rod 622 to rotate in the screw rod groove 6211 in the reverse direction. Figure 6 As shown, the first slider 623 is driven to move rightward by the screw rod 622 to push the push rod 624 to the right, and the push rod 624 pushes the second slider 641 to slide rightward to drive the movement of the two locking mechanisms 5. During the sliding process of the second slider 641, the sliding cooperation between the two third sliders 642 and the two limiting grooves limits the second slider 641, and the self-locking of the flip cover 4 is released by eliminating the squeezing and fixing of the two locking mechanisms 5 on the flip cover 4.

[0060] Remove the obstruction: When releasing the self-locking of the flip cover 4, Figure 6 As shown, in the process of pushing the push rod 624 to the right, the two push blocks 651 are driven to move to the right, and the two push blocks 651 drive the two arc-shaped push rods 653 to slide outward in the two plug-in slots 76, and the two arc-shaped push rods 653 are restricted from sliding by the two plug-in slots 76. When the first slider 623 moves to the rightmost side, the driving assembly 51 is closed, and the two arc-shaped push rods 653 push the two adapter blocks 652, so that the flip cover 4 is turned outward around the hinge axis, thereby completing the removal of the obstruction of the camera 3;

[0061] Photo upload: The controller 400 starts the camera 3 to take photos and videos of people nearby, and uploads the images and photos taken by the camera 3 to the database through the controller 400 for recording. When the power metering device is stolen, the thief can be tracked. The signal between the controller 400 and the database is connected in real time, so that the photos can be uploaded in time;

[0062] Blocking: When the infrared sensor 100 senses that a person is away, the driving assembly 51 is started to drive the driving gear 631 to flip, and the driving gear 631 drives the driven gear 632 to rotate forward, and the driven gear 632 drives the screw rod 622 to rotate, such as Figure 6 As shown, the screw rod 622 pushes the first slider 623 to move leftward, the first slider 623 drives the push rod 624 to move leftward, the push rod 624 drives the two push blocks 651 to move during the movement, the two push blocks 651 drive the arc-shaped push rod 653 to retract, the retracted two arc-shaped push rods 653 pull to reset the flip cover 4, the push rod 624 drives the second slider 641 to move leftward, the second slider 641 drives the two locking mechanisms 5 to insert into the two plug-in slots 76, the flip cover 4 is squeezed, fixed and locked by the two locking mechanisms 5, and the camera 3 is shielded;

[0063] Warning alarm: When the device is being stolen, the box 1 vibrates, and the vibration-sensitive buzzer alarm 200 senses the vibration and sounds an alarm, emitting an alarm buzzer and flashing lights. The alarm can be canceled by inserting an IC card dedicated to power work into the IC card plug-in block 79. However, when the alarm is canceled, a record will be left in the controller 400. The buzzing and flashing lights of the vibration-sensitive buzzer alarm 200 serve to warn people around.

[0064] Compared with the prior art, the present invention has the following beneficial effects:

[0065] 1. In this solution, when the push rod is pushed to the right, it drives the two push blocks to move to the right, and the two push blocks drive the two arc-shaped push rods to slide outward in the two plug-in slots, and the two arc-shaped push rods are restricted from sliding through the two plug-in slots. When the first slider moves to the far right, the three-phase asynchronous motor is turned off, and the two adapter blocks are pushed by the two arc-shaped push rods to make the flip cover flip outward around the hinge axis to complete the removal of the obstruction of the camera. The first slider drives the push rod to move to the left, and the push rod drives the two push blocks to move during the movement of the push rod. The movement of the two push blocks drives the arc-shaped push rods to retract, and the flip cover is reset by retracting the two arc-shaped push rods, and the flip cover is flipped by the two arc-shaped push rods. The second accommodating slot is sealed by the flip cover to block the camera, thereby protecting the camera from being damaged by thieves.

[0066] 2. In this solution, the IC card plug-in block is used to plug in the IC card, which is convenient for clearing the alarm during daily use and maintenance. When the alarm is cleared, a record will be left in the control terminal to record the subsequent maintenance management of the device, thereby improving maintenance efficiency.

[0067] 3. In this solution, the push rod pushes the second slider to the right to slide to the right, driving the movement of the two locking mechanisms. During the sliding process of the second slider, the sliding cooperation between the two third sliders and the two limit grooves limits the second slider. By eliminating the squeezing and fixation of the flip cover by the two locking mechanisms, the self-locking fixation of the flip cover is released, and the push rod drives the second slider to move to the left. The second slider drives the two locking mechanisms to insert into the two plug-in slots, and the flip cover is squeezed, fixed and locked by the two locking mechanisms to complete the shielding of the camera. By controlling the positional relationship of the two locking mechanisms, the flip cover can be fixed and locked or self-locking can be released to prevent the gap between the flip cover and the second accommodating groove from providing an opportunity for thieves to damage the camera.
