If the interior is not protected, the computer inside is very likely to be damaged due to external impact. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a computer mainframe that is convenient to disassemble, and solves the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A computer mainframe that is convenient to disassemble, including a main body. A servo motor is fixedly installed on the top of the main body. A box door is rotatably installed at the front of the main body. A protection device is arranged inside the main body. A wire winding device is arranged inside the main body. A cooling device is arranged inside the main body; The protection device includes a protection plate, a connecting plate, a moving plate, a clamping block, a limiting block, a connecting column, a telescopic block, a pressing plate, and a telescopic rod. An installation groove is opened on the top of the main body. The connecting plate is slidably installed inside the installation groove. The protection plate is fixedly installed on the right part of the connecting plate. The moving plate is arranged inside the main body. The limiting block is slidably installed on the top of the moving plate. A limiting groove is opened inside the main body. A groove is opened on the left part of the moving plate. The clamping block is slidably installed inside the groove. The connecting column slidably penetrates the moving plate. A clamping groove is opened on the circumferential surface of the connecting column. The telescopic block is slidably installed inside the clamping groove. The telescopic rod is fixedly installed at the bottom of the protection plate. By setting the protection device to protect the computer mainframe, when the invention is externally impacted, the computer mainframe inside can be fixed, preventing it from moving inside and colliding with each other and being damaged after being collided.

[0006] According to the above technical solution, a first elastic piece is fixedly installed between the connecting plate and the main body, a second elastic piece is fixedly installed between the clamping block and the moving plate, the clamping block contacts the connecting plate, and a first spring is fixedly installed between the moving plate and the main body. By setting the first elastic piece, it can be avoided that the protection plate moves due to a small force, resulting in the triggering of the protection device. By releasing the limit of the moving plate by the connecting plate, the first spring can press down the pressing plate to protect the computer.

[0007] According to the above technical solution, for a computer main unit that is easy to disassemble, it is characterized in that: a third elastic piece is fixedly installed between the telescopic block and the connecting column, and a second spring is fixedly installed between the moving plate and the pressing plate. The telescopic block is moved by the third elastic piece, and the moving plate and the pressing plate are connected by the second spring.

[0008] According to the above technical solution, the wire winding device includes a fixed block, a rotating shaft, a positioning block, a rotating wheel, a moving rod, a rotating rod and a cross bar. The fixed block is fixedly installed inside the main body, the positioning block is fixedly installed inside the main body, the rotating shaft is rotatably installed at the front of the fixed block, the rotating shaft rotatably penetrates the positioning block, the rotating wheel is fixedly installed at the front of the rotating shaft, a sliding groove is opened at the front of the fixed block, the moving rod is slidably installed inside the sliding groove, the moving rod slidably penetrates the positioning block, the rotating rod is rotatably installed at one end of the moving rod close to the rotating wheel, the cross bar is fixedly installed at the right end of the rotating rod, a limiting groove is opened on the circumferential surface of the rotating shaft, and a data cable is arranged on the circumferential surface of the rotating shaft. By setting the wire winding device, the too-long wire is wound up to prevent the too-long wire from interfering with the internal layout, and the wire is released when the main body is impacted, preventing the wire from being pulled and causing detachment or breakage.

[0009] According to the above technical solution, the top of the rotating rod is set as an arc surface, and a torsion spring is arranged between the rotating rod and the moving rod. By setting the torsion spring, it can be realized that when the rotating shaft is limited, it can be reversed to release the wire.

[0010] According to the above technical solution, the telescopic rod contacts the cross bar, and the elastic force of the telescopic rod is greater than the elastic force of the torsion spring. By the contact between the telescopic rod and the cross bar, the limit of the rotating shaft is released after the protection device is triggered, avoiding the wire from being pulled and causing detachment or breakage.

[0011] According to the above technical solution, the cooling device includes a filter screen, a lead screw, a moving block, a driving motor, a fan, a scraper, a collection box and a mounting plate. The filter screen is fixedly installed at the rear of the main body, the mounting plate is fixedly installed inside the main body, one end of the lead screw is fixedly installed at the output end of the servo motor, the other end of the lead screw is rotatably installed at the top of the mounting plate, the lead screw rotates through the top of the main body, the moving block is threadedly connected to the lead screw, the driving motor is fixedly installed at the front of the moving block, the fan is fixedly installed at the output end of the driving motor, the scraper is fixedly installed at the rear of the moving block, and the collection box is slidably installed at the rear of the main body. By setting up the cooling device, the temperature inside the main body is reduced to prevent the computer performance from being reduced due to excessive internal temperature.

[0012] According to the above technical solution, the scraper contacts the filter screen, and the scraper contacts the top of the collection box. By reciprocating movement of the moving block on the lead screw, the dust on the surface of the filter screen is cleaned by the scraper.

[0013] The present invention provides a computer mainframe that is easy to disassemble. It has the following beneficial effects: (1) In this invention, the movement of the protection plate drives the movement of the connecting plate. The movement of the connecting plate releases the limit on the moving plate. The moving plate moves downward under the elastic force of the first spring. The movement of the moving plate drives the movement of the connecting column. The movement of the connecting column drives the movement of the pressing plate. The pressing plate moves and contacts the top of the computer mainframe. The moving plate continues to move, causing the second spring to be compressed and deformed, making the connecting column move upward relative to the moving plate. The connecting column moves until the telescopic block is exposed. When the telescopic block is completely exposed, the telescopic block moves under the elastic force of the second elastic piece. The telescopic block contacts the limiting block. The telescopic block continues to move, causing the limiting block to move. The limiting block moves and snaps into the limiting groove to limit the movement of the moving plate and prevent the moving plate from driving the pressing plate to press down, preventing the pressing plate from continuously squeezing the computer mainframe and causing damage to the computer mainframe.

[0014] (2) In this invention, when the runner is rotated, the rotation of the runner drives the rotation of the rotating shaft. The rotation of the rotating shaft winds up the data cable, rolling up the overly long cable to prevent the overly long cable from interfering with the internal layout. As the rotating shaft rotates, the data cable gradually tightens. The tightened data cable gradually becomes straight. The straight data cable contacts the moving rod, causing the moving rod to move upward. The upward movement of the moving rod drives the upward movement of the rotating rod. The rotating rod moves upward and snaps into the limiting groove to limit the rotating shaft, preventing the cable winding device from continuing to wind the cable. At the same time, because the top of the rotating rod is set as an arc surface, when the rotating shaft is limited, it can be reversed to unwind the cable. When subjected to an external impact, the telescopic rod moves downward and contacts the cross bar. The telescopic rod continues to move downward, causing the cross bar to move downward. The downward movement of the cross bar causes the rotating rod to rotate. The rotation of the rotating rod releases the limit on the rotating shaft, allowing the wound cable to extend as the computer moves, avoiding the data cable from being stretched and causing the data cable to fall off or break after being collided.

[0015] (3) In this invention, the servo motor and the driving motor are started. Starting the servo motor causes the lead screw to rotate, and starting the driving motor causes the fan to rotate. The rotation of the fan cools the interior of this invention, preventing the computer performance from degrading due to excessive internal temperature. The rotation of the lead screw causes the moving block to move. The movement of the moving block drives the driving motor to move, and the movement of the driving motor drives the fan to move. The movement of the moving block drives the scraper to move, and the movement of the scraper cleans the surface of the filter screen, preventing dust accumulation on the filter screen from reducing the heat dissipation effect. The cleaned dust falls into the interior of the collection box. Description of the Drawings

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

By setting the protection device to protect the computer host, when the invention is impacted externally, the computer host inside can be fixed to prevent damage caused by the computer moving inside and colliding after being collided.

[0020] A first elastic piece is fixedly installed between the connecting plate 402 and the main body 1, a second elastic piece is fixedly installed between the clamping block 404 and the moving plate 403, the clamping block 404 is in contact with the connecting plate 402, and a first spring is fixedly installed between the moving plate 403 and the main body 1. By setting the first elastic piece, it can be avoided that the protection plate 401 moves due to a small force and the protection device is triggered. By releasing the limit of the connecting plate 402 on the moving plate 403, the first spring can press down the pressing plate 408 to protect the computer.

[0021] A third elastic piece is fixedly installed between the telescopic block 407 and the connecting column 406, and a second spring is fixedly installed between the moving plate 403 and the pressing plate 408. The telescopic block 407 is moved by the third elastic piece, and the moving plate 403 and the pressing plate 408 are connected by the second spring.

[0022] The wire winding device includes a fixed block 501, a rotating shaft 502, a positioning block 503, a rotating wheel 504, a moving rod 505, a rotating rod 506 and a cross bar 507. The fixed block 501 is fixedly installed inside the main body 1, and the positioning block 503 is fixedly installed inside the main body 1. The rotating shaft 502 is rotatably installed at the front of the fixed block 501. The rotating shaft 502 rotatably penetrates through the positioning block 503. The rotating wheel 504 is fixedly installed at the front of the rotating shaft 502. A sliding groove is formed at the front of the fixed block 501. The moving rod 505 is slidably installed inside the sliding groove. The moving rod 505 slidably penetrates through the positioning block 503. The rotating rod 506 is rotatably installed at one end of the moving rod 505 close to the rotating wheel 504. The cross bar 507 is fixedly installed at the right end of the rotating rod 506. A limiting groove is formed on the circumferential surface of the rotating shaft 502. A data cable 7 is arranged on the circumferential surface of the rotating shaft 502. By arranging the wire winding device, the too long wire is wound up to prevent the too long wire from interfering with the internal layout, and when the main body 1 is impacted, the wire is paid out to prevent the wire from being pulled off or broken.

[0023] The top of the rotating rod 506 is set as an arc surface. A torsion spring is arranged between the rotating rod 506 and the moving rod 505. By arranging the torsion spring, when the rotating shaft 503 is limited, it can be reversed to pay out the wire.

[0024] The telescopic rod 409 contacts with the cross bar 507, and the elastic force of the telescopic rod 409 is greater than the elastic force of the torsion spring. By the contact between the telescopic rod 409 and the cross bar 507, the limit on the rotating shaft 502 is released after the protection device is triggered, avoiding the wire from being pulled off or broken.

[0025] When this embodiment works: when the device is impacted externally, when the protection plate 401 is impacted, it moves. The movement of the protection plate 401 drives the connecting plate 402 to move. The movement of the connecting plate 402 releases the limit on the moving plate 403. The moving plate 403 moves downward under the elastic force of the first spring. The movement of the moving plate 403 drives the connecting column 406 to move. The movement of the connecting column 406 drives the pressing plate 408 to move. The pressing plate 408 moves and contacts the top of the computer main unit. The moving plate 403 continues to move, causing the second spring to be deformed by force, so that the connecting column 406 moves upward relative to the moving plate 403. The connecting column 406 moves until the telescopic block 407 is exposed. After the telescopic block 407 is completely exposed, the telescopic block 407 moves under the elastic force of the second elastic piece. The telescopic block 407 contacts with the limiting block 405. The telescopic block 407 continues to move, causing the limiting block 405 to move. The limiting block 405 moves and is clamped into the limiting groove to limit the moving plate 403, preventing the pressing plate 408 from continuously squeezing the computer main unit and causing damage to the computer main unit.

[0026] Under normal circumstances, insert the data cable 7 into the computer host. Wind the remaining data cable 7 around the surface of the rotating shaft 502 from below the moving rod 505. Rotate the rotating wheel 504. The rotation of the rotating wheel 504 drives the rotation of the rotating shaft 502. The rotation of the rotating shaft 502 winds up the data cable 7. As the rotating shaft 502 rotates, the data cable 7 gradually tightens. The tightened data cable 7 gradually becomes straight. The straight data cable 7 contacts the moving rod 505, thereby causing the moving rod 505 to move upward. The upward movement of the moving rod 505 drives the upward movement of the rotating rod 506. The upward movement of the rotating rod 506 is inserted into the limiting groove to limit the rotating shaft 502, so that the wire winding device cannot continue to wind the wire. When subjected to an external impact, the telescopic rod 409 moves downward to contact the cross bar 507. The continuous downward movement of the telescopic rod 409 causes the cross bar 507 to move downward. The downward movement of the cross bar 507 causes the rotating rod 506 to rotate. The rotation of the rotating rod 506 releases the limit on the rotating shaft 502.

[0027] Please refer to Figures 1-7 , on the basis of the above embodiment, in another embodiment of the present invention, a cooling device is provided inside the main body 1. The cooling device includes a filter screen 601, a lead screw 602, a moving block 603, a drive motor 604, a fan 605, a scraper 606, a collection box 607 and a mounting plate 608. The filter screen 601 is fixedly installed at the rear of the main body 1. The mounting plate 608 is fixedly installed inside the main body 1. One end of the lead screw 602 is fixedly installed at the output end of the servo motor 2. The other end of the lead screw 602 is rotatably installed at the top of the mounting plate 608. The lead screw 602 rotates through the top of the main body 1. The moving block 603 is threadedly connected to the lead screw 602. The drive motor 604 is fixedly installed at the front of the moving block 603. The fan 605 is fixedly installed at the output end of the drive motor 604. The scraper 606 is fixedly installed at the rear of the moving block 603. The collection box 607 is slidably installed at the rear of the main body 1. By providing the cooling device, the temperature inside the main body 1 is reduced to prevent the computer performance from being reduced due to excessive internal temperature.

[0028] The scraper 606 contacts the filter screen 601 and the top of the collection box 607. By reciprocating movement of the moving block 603 on the lead screw 602, the scraper 606 cleans the dust on the surface of the filter screen 601.

[0029] When this embodiment works: When the invention works, turn on the power supply, and the servo motor 2 and the drive motor 604 are started. The start of the servo motor 2 causes the lead screw 602 to rotate. The start of the drive motor 604 causes the fan 605 to rotate. The rotation of the lead screw 602 causes the moving block 603 to move. The movement of the moving block 603 drives the movement of the drive motor 604. The movement of the drive motor 604 drives the movement of the fan 605. The movement of the moving block 603 drives the movement of the scraper 606. The movement of the scraper 606 cleans the surface of the filter screen 601. The cleaned dust falls into the collection box 607.
