[0043] Reference example Figures 1 to 10 A microcomputer integrated protection device includes a panel 1 and a top plate 2. A carrying plate 11 is provided on the back of the panel 1. Rotatable side plates 3 are provided on both sides of the carrying plate 11. The carrying plate 11 is also provided with a rotatable back plate 4. The side plates 3 are provided with a first fixing portion 31 and are perpendicular to the side plates 3. Damping components 5 are provided on both sides of the back plate 4 and abut against the carrying plate 11. The back plate 4 is provided with a second fixing portion 41 and is perpendicular to the back plate 4. The panel 1 is provided with a slot 12, and the top plate 2 is inserted into the slot 12. The top plate 2 is provided with a guide groove 21 for the first fixing portion 31 to penetrate. The top plate 2 is also provided with a makeshift groove 22 for the second fixing portion 41 to be inserted. The top plate 2 is provided with a liftable movable plate 6. The movable plate 6 is provided with a plurality of insert blocks 61 and passes through the first fixing portion 31 and the second fixing portion 41.

[0044] It is worth mentioning that first hinge holes 13 are provided at both ends of both sides of the carrying plate 11, and second hinge holes 14 are provided on the carrying plate 11. Arc surfaces 15 are provided between the first hinge holes 13, and bearing portions 16 are provided on both sides of the carrying plate 11. The first hinge holes 13 allow the side panels 3 to rotate around the axis, and the second hinge holes 14 allow the back panel 4 to rotate around the axis. The arc surfaces 15 fit the shape of the bottom of the side panels 3 and play a role in avoiding position. The bearing portions 16 provide support for the side panels 3 and limit the rotation range of the side panels 3.

[0045] It is worth mentioning that the first fixing portion 31 is provided with a first fixing hole 311 , and the second fixing portion 41 is provided with a second fixing hole 411 . The first fixing hole 311 and the second fixing hole 411 are used in conjunction with the insert block 61 .

[0046] It is worth mentioning that the side panel 3 is provided with a plurality of heat dissipation holes 32. A first shaft 33 is provided on both sides of the side panel 3 and is hinged to the first hinge hole 13. The heat dissipation holes 32 allow the internal electronic components to exchange heat with the external air. The first shaft 33 cooperates with the first hinge hole 13.

[0047] It is worth mentioning that first blind holes 42 are provided on both sides of the back plate 4, and limiting through holes 43 are provided on both sides of the first blind hole 42. The first blind hole 42 is provided with a second shaft 44 and is hinged to the second hinge hole 14. The first blind hole 42 provides a guide for the top column 51 and also provides an accommodation space for the first spring 52. The limiting through holes 43 limit the telescopic range of the top column 51, making it easier for the back plate 4 to be assembled to the supporting plate 11. The second shaft 44 cooperates with the second hinge hole 14.

[0048] It is worth mentioning that the damping assembly 5 includes a top column 51 and a first spring 52. The top column 51 is slidably arranged in the first blind hole 42. A limit portion 511 is provided on both sides of the top column 51 and is slidably arranged in the limit through hole 43. The first spring 52 abuts against the top column 51 and the first blind hole 42 respectively, so that the top column 51 abuts against the supporting plate 11. The elastic force of the first spring 52 is applied to the top column 51, so that the top column 51 is tightly attached to the supporting plate 11, thereby increasing the friction between the back plate 4 and the supporting plate 11, thereby preventing the back plate 4 from being subjected to excessive tension or rotating too fast, resulting in the problem of loose connection between the wire of the connection port and the circuit board.

[0049] It is worth mentioning that the top plate 2 is provided with at least two threaded holes 23, and the threaded holes 23 are provided with second blind holes 24. The threaded holes 23 are used in conjunction with the fastening screws 7, and the second blind holes 24 provide a space for accommodating the second spring 25.

[0050] It is worth mentioning that the movable plate 6 is provided with a fastening screw 7 corresponding to the threaded hole 23, and a retaining ring 71 is provided at the end of the fastening screw 7. The second blind hole 24 is provided with a second spring 25, and abuts against the movable plate 6. The fastening screw 7 is rotated to insert the insert block 61 into the first fixing hole 311 and the second fixing hole 411, and the fastening screw 7 passes through the movable plate 6. Therefore, the fastening screw 7 also provides a guiding effect for the movable plate 6, and the elastic force released by the second spring 25 gives the movable plate 6 to make it move upward, and the retaining ring 71 limits the rising moving distance of the fastening screw 7.

[0051] The operating principle of the present invention is now described as follows:

[0052] Example 1

[0053] When the microcomputer integrated protection device needs to be repaired, the fastening screw 7 is loosened to move it upward, and the second spring 25 gradually releases its elastic force to the movable plate 6, causing the insert 61 to gradually leave the first fixing hole 311 and the second fixing hole 411 until the retaining ring 71 abuts the top plate 2. At this time, the connection between the side plate 3, the back plate 4 and the top plate 2 is released;

[0054] First, rotate the back plate 4 so that the second fixing portion 41 leaves the clearance groove 22, and then pull the top plate 2 outward to make it leave the side plate 3. At this time, the side plate 3 can be rotated freely. When the side plate 3 is rotated to the right position, it will abut the bearing portion 16. The circuit board installed on the bearing plate 11 is completely exposed to the field of vision, so that it is convenient for maintenance personnel to perform maintenance on it. Figure 2 shown.

[0055] Example 2

[0056] After the repair is completed, first rotate the side panel 3 to its original position, take the top panel 2 and align the guide groove 21 with the first fixing part 31, apply thrust to the top panel 2, and insert the top panel 2 into the slot 12 so that the top panel 2 is pre-connected and fixed with the panel 1. Finally, rotate the back panel 4 so that the second fixing part 41 is inserted into the makeshift groove 22, rotate the fastening screw 7, and gradually lower the movable panel 6, and compress the second spring 25 to gradually store energy. The insert block 61 is inserted into the first fixing hole 311 and the second fixing hole 411 to complete the connection between the side panel 3, the back panel 4 and the top panel 2.

[0057] The above design scheme can make the product easy to repair and dismantle.

[0058] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, they can make several simple deductions or substitutions without departing from the concept of the present invention, which should be regarded as falling within the scope of protection determined by the claims submitted for the present invention.
