The spring inside the support plate 203 pulls the panel 201 to be placed on the front side of the carrier plate 102, and the cross bar 204 is inserted into the side of the panel 201 to prevent the panel 201 from moving randomly. After the work is completed, pull the bracket 202 again to close the display screen on the front side of the panel 201 on the front side of the carrier plate 102 to protect the display screen; for the heat dissipation component 3, the inner groove 301 inside the heat dissipation component 3 is provided inside the side wall of the main body 1, and the card slot 306 inside the heat dissipation component 3 is provided on the rear side of the panel 201, and the heat dissipation component 3 is installed on the side of the main body 1; for the collection structure 4, the collection structure 4 is installed inside the main body 1, and the guide wheel 403 inside the collection structure 4 is installed on the inner side wall of the vertical groove 101 through a rotating shaft. After the work is completed, rotate the top plate 407 so that the push blocks at both ends of it lose the pressure on the pressing plate 406. Under the action of the spring, the pressing plate 406 moves to one side, causing the rotating plate 404 to drive the rotating rod 402 to rotate, so that the wires are orderly collected into the inner cavity 401 for storage, preventing the wires from being wound and not being easy to sort out.

[0034] Among them, the heat dissipation member 3 includes an inner groove 301. An inclined slot is provided on the side surface of the inner groove 301, and the inclined slot on the side surface of the inner groove 301 is connected to the heat dissipation holes on the side surface of the body 1; an inner plate 302, with inclined heat dissipation holes provided on the side surface of the inner plate 302, and the top edge position of the side surface of the inner plate 302 is of an inclined structure, and the inner plate 302 is installed inside the inner groove 301 through a spring; a vertical plate 303, the vertical plate 303 is of a rectangular plate structure, and the vertical plate 303 is installed inside the inner groove 301; a push plate 304 has a guiding function, the push plate 304 is of a wedge-shaped structure, and the push plate 304 is installed at the top of the side surface of the vertical plate 303, and the push plate 304 is slidably installed at the top edge position of the side surface of the inner plate 302; a plug rod 305, the plug rod 305 is of a cylindrical structure, and the plug rod 305 passes through the inside of the carrier plate 102 and is connected to the vertical plate 303; a clamping groove 306 allows the clamping plate 307 to have a space to move outwards, the clamping groove 306 is of a rectangular frame structure, and a clamping plate 307 is installed inside the clamping groove 306; a clamping plate 307, the clamping plate 307 is installed on the front side of the carrier plate 102 through a spring, and the side surface of the clamping plate 307 is connected to the plug rod 305. When the panel 201 is flipped, the clamping plate 307 slides into the inside of the clamping groove 306 under the push of the spring, and the clamping plate 307 drives the vertical plate 303 to move inside the inner groove 301 through the plug rod 305, so that the push plate 304 loses the pressure on the inner plate 302. Under the action of the spring, the inner plate 302 moves upwards, so that the heat dissipation holes on the side surface of the inner plate 302 are communicated with the heat dissipation holes on the side surface of the body 1. When the panel 201 is in use, the heat dissipation holes are opened to ensure the heat dissipation effect of the power data recorder and extend the service life. When the panel 201 is closed, the front side of the panel 201 pushes the spring on the side surface of the clamping plate 307 to contract, drives the vertical plate 303 to move through the plug rod 305, makes the push plate 304 slide on the inclined structure at the top edge position of the side surface of the inner plate 302, and makes the inner plate 302 move downwards inside the inner groove 301 to block the heat dissipation holes on the side surface of the body 1, preventing dust in the air from adhering to the electronic components when not working.

At the same time, a motor and a fan blade are installed on the side surface of the inner plate 302, and the fan blade is driven by the motor to rotate to actively dissipate the heat inside the body 1.

[0036] Among them, the collection structure 4 includes: The inner cavity 401 functions to store wires. The inner cavity 401 is a rectangular structure and is provided inside the body 1; The rotating rod 402 is a cylindrical structure, and wires and a power detection rod are installed on the outer side of the rotating rod 402. The bottom end of the rotating rod 402 is installed inside the inner cavity 401 through a rotating shaft; The guide wheel 403 enables the wires to move orderly and positions the movement of the wires. An annular groove is provided on the outer side of the guide wheel 403, and the wires on the outer side of the rotating rod 402 are installed in the annular groove on the outer side of the guide wheel 403; The rotating plate 404 has a jack on its top and is installed on the top of the rotating rod 402; The top groove 405 has a T-shaped structure on its side surface to guide and store the movement of the pressing plate 406. The top groove 405 is provided inside the top end of the body 1, and the rotating plate 404 is installed inside the top groove 405; The pressing plate 406 has a rubber pad on its side surface and is installed inside the top groove 405 through a spring. The side surface of the pressing plate 406 is an arc-shaped structure, and the side surface of the pressing plate 406 is installed on the outer side of the rotating plate 404; The top plate 407 is an oval structure, and a push block is installed on the distal side surface of the top plate 407 through a spring.

When the power data recorder is connected to an electrical appliance or other device, the wire is pulled outwards according to the length of use. The wire drives the rotating rod 402 to rotate inside the inner cavity 401, and at the same time, the rotating plate 404 rotates inside the top groove 405. Under the action of the springs on the side surfaces of the push blocks at both ends of the top plate 407, the rubber pad on the side surface of the pressing plate 406 can increase the friction force of the rotation of the rotating plate 404, prevent the speed of the guide being pulled outwards from being too fast, resulting in too long a length of the guide being pulled, and reduce the problem of winding. The two guide wheels 403 guide the direction of the wire to prevent the wire from being cut by the edge.

[0037] When using the power data recorder, first, make the display screen on the front side of the panel 201 face forward. Pull the bracket 202 outward manually to flip the panel 201. Under the pull of the spring, the panel 201 is placed on the front side of the carrier plate 102, and the display screen on the front side of the panel 201 works. While the panel 201 is flipping, the clamping plate 307 slides into the card slot 306 under the push of the spring. The clamping plate 307 drives the vertical plate 303 to move through the insertion rod 305. The push plate 304 loses the pressure on the inner plate 302, and under the action of the spring, the inner plate 302 moves upward. The heat dissipation holes on the side of the inner plate 302 are connected to the heat dissipation holes on the side of the main body 1 to ventilate and dissipate heat for the power data recorder, extending its service life. Then, pull the wire outward according to the actual use requirements. The wire drives the rotating rod 402 and the rotating plate 404 to rotate. The push block on the outer side of the distal end of the top plate 407 pushes the pressing plate 406 under the action of the spring to increase the friction force of the rotating plate 404 rotating, so that the wire is gradually pulled out, reducing the problem of entanglement caused by too long wire. Operate the display screen on the panel 201 through the operation buttons on the front side of the bottom end of the carrier plate 102. When powered off, the backup battery inside the main body 1 works to ensure the complete preservation of data. After the work is completed, pull the bracket 202 again to close the display screen on the panel 201 in front of the carrier plate 102 for protection. At the same time, the panel 201 pushes the clamping plate 307 to move, and the push plate 304 pushes the inner plate 302 to move downward to block the heat dissipation holes on the side of the main body 1, preventing the entry of dust.
