DETAILED DESCRIPTION

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0027] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, it is a structural diagram of a portable computer maintenance device provided by an embodiment of the present invention, comprising a box body 1, a box cover 11 is hingedly installed at the opening of the box body 1, a handle 12 is arranged on the side wall of the box body 1, two groups of relatively distributed carrying plates 2 are rotatably installed in the inner cavity of the box body 1, the two groups of the carrying plates 2 are staggered in the vertical direction of the inner cavity of the box body 1, and the two opposite side walls of the two groups of carrying plates 2 are rotatably installed with carrying plates 3, and the surface of the carrying plates 3 is provided with a clamping mechanism 4, and the clamping mechanism 4 includes a pressing component 41 and a rotating component 42, and the pressing component 41 is located on the surface of the two groups of carrying plates 3, and the pressing component 41 is used to clamp the computer between the two groups of carrying plates 3 The rotating component 42 is located on the surface of the carrier plate 2 and is connected to the carrier disc 3. The rotating component 42 is used to control the rotation of the carrier disc 3 on the surface of the carrier plate 2 and thereby adjust the position angle of the computer between the two groups of carrier discs 3. A positioning mechanism 5 is provided on the surface of the carrier plate 2. The positioning mechanism 5 includes a storage component 51 and a limit component 52. The storage component 51 is located on the side wall of the carrier plate 2. When the box body 1 is in a closed state, the storage component 51 controls the two groups of carrier plates 2 to maintain a horizontal state in the inner cavity of the box body 1. The limit component 52 is located on the side wall of the carrier plate 2. When the box body 1 is in an open state, the limit component 52 is used to control the two groups of carrier plates 2 to rotate to a vertical state on the outside of the box body 1.

[0029] Initially, the box cover 11 is fixed on the surface of the box body 1 , and the box body 1 remains in a closed state. The storage assembly 51 supports and positions the two groups of supporting plates 2 in the inner cavity of the box body 1 , and the two groups of supporting plates 2 remain stably horizontal in the inner cavity of the box body 1 . When the computer needs to be repaired, the box cover 11 is opened, and the two groups of supporting plates 2 are rotated to a vertical state. At this time, the two groups of supporting plates 2 drive the supporting disc 3 to extend to the outside of the box body 1. The limiting assembly 52 cooperates with the side wall of the box body 1 to fix the position of the supporting plate 2. At this time, the two groups of supporting plates 2 are stably maintained in a vertical state, and the supporting discs 3 on the surfaces of the two groups of supporting plates 2 are relatively distributed. The computer is inserted between the two groups of supporting discs 3. The extrusion assembly 41 can conveniently clamp and fix the computer. After the computer is fixed between the two groups of supporting discs 3, the staff can conveniently repair the computer. During the repair process, when the position of the computer needs to be adjusted, the rotating assembly 42 controls the two groups of supporting discs 3 to rotate a certain angle on the surface of the supporting plate 2. The supporting disc 3 cooperates with the extrusion assembly 41 to drive the computer to rotate synchronously. After the computer is rotated to a suitable repair angle, the rotating assembly 42 fixes the position of the supporting disc 3 at the side wall of the supporting plate 2. At this time, the computer can be efficiently repaired. After the computer is processed, the computer can be easily pulled out from between the two groups of carrier plates 3 through the squeezing component 41, and the limiting component 52 releases the restriction on the carrier plate 2, and the carrier plate 2 is rotated to the inner cavity of the box 1. The storage component 51 controls the two groups of carrier plates 2 to maintain a stable horizontal state in the inner cavity of the box 1 again, and the staff can hold the handle 12 to easily carry the box 1.

[0030] like Figure 1 , Figure 4 , Figure 5 As shown, as a preferred embodiment of the present invention, the extrusion assembly 41 includes two groups of vertical grooves 411 respectively opened on the opposite side walls of the carrying plate 3, and two groups of relatively distributed clamping plates 412 are slidably installed in the vertical grooves 411. Extrusion springs 413 are fixedly installed at both ends of the vertical grooves 411, and the telescopic ends of the extrusion springs 413 are connected to the clamping plates 412. The clamping plates 412 extend to the outside of the carrying plate 3, and arc-shaped guide plates 414 are fixedly installed at both ends of the clamping plates 412 located on the outside of the carrying plate 3.

[0031] The extrusion spring 413 applies a thrust to the two groups of clamping plates 412 in the vertical groove 411, and the two groups of clamping plates 412 fit together. After the two groups of supporting plates 2 rotate to the outside of the box body 1 and maintain a vertical state, the computer is inserted between the two groups of supporting plates 3. Further, the computer is inserted from between the two groups of guide plates 414 to between the two groups of clamping plates 412. The extrusion spring 413 applies a thrust to the clamping plates 412. The two groups of clamping plates 412 at both ends of the computer can stably clamp and fix the computer. After the position of the computer is fixed, the staff can efficiently repair the computer.

[0032] like Figure 1 , Figure 4 , Figure 6 , Figure 7 , Fig. 9 As shown, as a preferred embodiment of the present invention, the rotating component 42 includes a plurality of groups of snap-in holes 421 distributed in a ring shape with equal intervals and opened on a side wall of the carrying plate 2 toward the carrying plate 2, a through hole 422 is opened on the surface of the carrying plate 2, a fixing rope 423 is fixedly installed on the surface of the carrying plate 2, a positioning plate 424 is fixedly installed on one end of the fixing rope 423 away from the carrying plate 2, and a snap-in column 425 that cooperates with the snap-in hole 421 is fixedly installed on the surface of the positioning plate 424.

[0033] Initially, the positioning plate 424 is in contact with the surface of the carrier plate 2. At this time, the clamping column 425 on the surface of the positioning plate 424 passes through the through hole 422 and is inserted into the clamping hole 421 on the surface of the carrier disk 3. The clamping column 425 cooperates with the clamping hole 421 to fix the position of the carrier disk 3 on the surface of the carrier plate 2, effectively preventing the carrier disk 3 from rotating. When the position angle of the computer needs to be adjusted, the positioning plate 424 is held and the clamping column 425 is pulled out from the clamping hole 421. At this time, the clamping column 425 releases the restriction on the carrier disk 3, and the carrier disk 3 can rotate freely on the surface of the carrier plate 2, and the position angle of the computer can be adjusted synchronously. After the computer is adjusted to a suitable maintenance angle, the positioning plate 424 is held and the clamping column 425 is inserted into the clamping hole 421 at the corresponding position again. At this time, the position of the carrier disk 3 can be fixed again on the surface of the carrier plate 2.

[0034] like Fig. 9 As shown, as a preferred embodiment of the present invention, the positioning plate 424 is made of magnetic material, and a magnetic sheet 7 located outside the through hole 422 and cooperating with the positioning plate 424 is fixedly mounted on the surface of the supporting plate 2 .

[0035] After the clamping column 425 passes through the through hole 422 and is inserted into the clamping hole 421, the positioning plate 424 and the surface of the supporting plate 2 are in contact with each other, and the magnetic sheet 7 uses magnetic attraction to adsorb and position the positioning plate 424, which can effectively improve the stability of the positioning plate 424 and the clamping column 425.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, as a preferred embodiment of the present invention, the storage assembly 51 includes two groups of support columns 511 fixedly installed on the surfaces of the two supporting plates 2, the bottom ends of the support columns 511 on the surface of the lower supporting plate 2 are in contact with the inner bottom wall of the box body 1, and the bottom ends of the support columns 511 on the surface of the upper supporting plate 2 are in contact with the surface of the lower supporting plate 2, and the inner side wall of the box cover 11 is fixedly installed with a compression pad 512 that cooperates with the upper supporting plate 2.

[0037] When the box body 1 is in a closed state, the two groups of supporting plates 2 are located in the inner cavity of the box body 1, and the two groups of supporting columns 511 support the supporting plates 2 in the inner cavity of the box body 1. At this time, the supporting plates 2 remain in a horizontal state, and the squeezing pads 512 on the bottom wall of the box cover 11 fit together with the supporting plates 2 above. The squeezing pads 512 apply pressure to the supporting plates 2, which can further improve the stability of the two groups of supporting plates 2 in the inner cavity of the box body 1, and effectively prevent the supporting plates 2 from shaking in the inner cavity of the box body 1 when the box body 1 is carried.

[0038] like Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 8 As shown, as a preferred embodiment of the present invention, the limit assembly 52 includes telescopic grooves 521 respectively opened on the two side walls opposite to each other of two groups of supporting plates 2, and multiple groups of parallel distributed guide rods 522 are fixedly installed in the telescopic grooves 521. The multiple groups of guide rods 522 are slidably installed together with a limit plate 523, and the vertical cross-section of the limit plate 523 is an L-shaped structure and is snap-fitted with the side wall of the box body 1.

[0039] The limit plate 523 slides along the surface of the guide rod 522, and the position of the limit plate 523 can be easily adjusted. After the two groups of bearing plates 2 rotate to a vertical state and extend to the outside of the box body 1, the limit plate 523 slides to the lowest point of the telescopic slot 521 under the action of gravity. At this time, the limit plate 523 is clamped to the outside of the side wall of the box body 1. The limit plate 523 cooperates with the side wall of the box body 1 to position the bearing plate 2, and the bearing plate 2 can be stably kept in a vertical state. After the computer is repaired, the limit plate 523 is pushed upward to separate the limit plate 523 from the side wall of the box body 1. At this time, the limit plate 523 releases the restriction on the bearing plate 2, and the bearing plate 2 can be rotated to the inner cavity of the box body 1 for storage.

[0040] like Figure 2 , Figure 4 As shown, as a preferred embodiment of the present invention, a tool storage cavity 6 which cooperates with the carrier plate 3 is fixedly installed at the bottom of the box body 1 .

[0041] The tools needed for computer maintenance are placed in the tool storage cavity 6. When the box body 1 is closed, the carrier plate 3 on the surface of the carrier plate 2 below fits with the top opening of the tool storage cavity 6. At this time, the tool storage cavity 6 is in a closed state, which is convenient for storing and storing maintenance tools.

[0042] like Figure 1 , Figure 6 As shown, as a preferred embodiment of the present invention, a handle 8 is provided on the surface of the carrying plate 2 .

[0043] The working principle of the present invention is: initially, the box cover 11 is fixed on the surface of the box body 1, at which time the box body 1 remains in a closed state, two groups of supporting plates 2 are located in the inner cavity of the box body 1, and two groups of supporting columns 511 support the supporting plates 2 in the inner cavity of the box body 1. At this time, the supporting plates 2 remain in a horizontal state, and the squeezing pad 512 on the bottom wall of the box cover 11 fits with the supporting plate 2 above. The squeezing pad 512 applies pressure to the supporting plates 2, which can further improve the stability of the two groups of supporting plates 2 in the inner cavity of the box body 1.

[0044] When the computer needs to be repaired, the case cover 11 is opened and the two groups of supporting plates 2 are rotated to a vertical state. At this time, the two groups of supporting plates 2 drive the supporting plates 3 to extend to the outside of the case 1. The limit plate 523 slides to the lowest point of the telescopic slot 521 under the action of gravity. At this time, the limit plate 523 is clamped to the outside of the side wall of the case 1. The limit plate 523 cooperates with the side wall of the case 1 to position the supporting plate 2, and the supporting plate 2 can stably maintain a vertical state.

[0045] After the two groups of carrier plates 2 rotate to the outside of the box 1 and maintain a vertical state, insert the computer between the two groups of carrier plates 3. Further, insert the computer from between the two groups of guide plates 414 to between the two groups of clamping plates 412. The compression spring 413 applies a thrust to the clamping plate 412. The two groups of clamping plates 412 at both ends of the computer can stably clamp and fix the computer. After the position of the computer is fixed, the staff can efficiently repair the computer. When it is necessary to adjust the position angle of the computer, hold the positioning plate 424 and pull the clamping column 425 out of the clamping hole 421. At this time, the clamping column 425 releases the restriction on the carrier plate 3. The carrier plate 3 can rotate freely on the surface of the carrier plate 2 and can adjust the position angle of the computer synchronously. After the computer is adjusted to a suitable inspection angle, hold the positioning plate 424 and insert the clamping column 425 into the clamping hole 421 at the corresponding position again. At this time, the position of the carrier plate 3 can be fixed again on the surface of the carrier plate 2.

[0046] After the computer is repaired, the limit plate 523 is pushed upward to separate the limit plate 523 from the side wall of the box body 1. At this time, the limit plate 523 releases the restriction on the supporting plate 2, and the supporting plate 2 can be rotated to the inner cavity of the box body 1 for storage.

[0047] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
