[0003] In the prior art, for example, a Chinese patent with publication number CN 218455866 U discloses a computer case that is easy to assemble, which includes a bottom frame, a top frame is arranged above the bottom frame, and a side frame is arranged between the bottom frame and the top frame, the top and bottom of the side frame are fixedly connected with positioning bars, the top of the bottom frame and the bottom of the top frame are both provided with positioning grooves that are nested and slidably matched with the positioning bars, the side frame is provided with two movable grooves, and the two movable grooves are both slidably connected with plug rods, and springs 1 are connected between the inner walls of the two movable grooves and one end of the two plug rods, and the two plug rods are fixedly connected with toggle rods, and the top of the bottom frame and the bottom of the top frame are both provided with slots. This patent can make the side frame, the top frame and the bottom frame firmly positioned and docked and installed through the coordinated arrangement of the positioning bar, the positioning groove, the plug rod, the spring 1, the slot and other structures, so as to form a firm and stable computer housing frame structure, which is convenient for computer equipment to be installed inside.

[0004] However, the above patent has some shortcomings. In actual use, when assembling and disassembling the cover plate, the above patent needs to control four toggle blocks and operate them simultaneously. In addition, the distance between the four toggle blocks is far, which makes it difficult to operate them synchronously with one hand, resulting in inconvenience in disassembly. Therefore, a computer case that is easy to assemble is proposed to solve the above problem. Utility Model Content

[0005] In order to solve the above technical problems, the utility model proposes a computer case for a computer that is easy to assemble. The buckle devices on both sides can be synchronously controlled by a set knob, thereby improving convenience during the disassembly and assembly process.

[0006] The technical solution for achieving the purpose of the present utility model is as follows: A computer case convenient for assembly for a computer, comprising two first side plates and two second side plates. The opposite surfaces of the two first side plates and the two second side plates are respectively rotatably connected to a top plate and a bottom plate through rotating shafts. Both sides of the top plate are fixedly connected with fixing blocks. One side of each of the two fixing blocks is provided with an installation groove. The inner walls of the two installation grooves are respectively rotatably connected with gears through damping rotating shafts. One end of each of the two damping rotating shafts is fixedly installed with a knob. The two inner side walls of the installation groove are respectively slidably connected with a first rack and a second rack. The first rack and the second rack are respectively engaged with the gear. One side of the fixing block is provided with two rectangular grooves. The inner bottom walls of the two rectangular grooves are respectively provided with sliding grooves. The inner walls of the two sliding grooves are respectively slidably connected with a second sphere. One end of the first rack is fixedly connected with a connecting rod. One ends of the connecting rod and the second rack are respectively fixedly connected to the surfaces of the corresponding two second spheres. Two limiting holes are penetratedly opened in the inner walls of the installation groove and the two rectangular grooves. The two limiting holes are respectively slidably connected with the surfaces of the first rack and the second rack.

[0007] In some embodiments, two limiting grooves are commonly opened on the bottom plate, the top plate, the two first side plates and the two second side plates. The inner walls of the two limiting grooves are respectively slidably connected with a cover plate. Two clamping grooves are opened on the opposite surfaces of the two cover plates.

[0008] In some embodiments, a fixing plate is fixedly connected to the inner wall of the rectangular groove. A sliding hole is opened on one side of the fixing plate. A sliding rod is slidably connected to the inner wall of the sliding hole. One end of the sliding rod is fixedly connected with a trapezoidal block. The surface of the trapezoidal block is adapted to and slidably connected with the inner wall of the clamping groove.

[0009] In some embodiments, a spring is sleeved on the surface of the sliding rod. Two ends of the spring are respectively fixedly connected to the opposite surfaces of the fixing plate and the trapezoidal block. The surface of the trapezoidal block is slidably connected with the inner wall of the rectangular groove. One end of the sliding rod away from the trapezoidal block is fixedly connected with a first sphere.

[0010] In some embodiments, heat dissipation nets are arranged on the surfaces of the top plate and one of the cover plates. Positioning rods are fixedly connected to one sides of the two first side plates. Positioning cylinders are fixedly connected to one sides of the two second side plates. The surfaces of the two positioning rods are respectively slidably connected with the inner walls of the corresponding two positioning cylinders.

[0011] Compared with the prior art, the present utility model has the following remarkable advantages:

[0012] First: By rotating the knob of the present utility model, the rotation of the knob drives the rotation of the gear. The rotation of the gear can drive the movement of the first rack and the second rack respectively, so that the first rack and the second rack drive the two second spheres to move away from each other. Through the design of the chute, the movement stability of the two second spheres can be improved. When the two second spheres move away from each other, they can squeeze the movement of the two first spheres, thereby driving the sliding rod to slide, realizing the movement of the trapezoidal block towards the outside of the card slot, and realizing the separation of the trapezoidal block from the card slot. At this time, the cover plate can be pulled out, and the operation is convenient.

[0013] Second: Rotate the two first side plates and the two second side plates to the vertical positions on the top plate and the bottom plate respectively, and then insert the positioning rod into the positioning cylinder to complete the assembly of the side plates. Then, place the arc surfaces of the two cover plates downward and insert them into the limiting grooves. During the insertion process, the bottom end of the arc first contacts the trapezoidal block, which will squeeze the trapezoidal block to retract into the rectangular groove. Until the card slot opened on the cover plate contacts the trapezoidal block, the trapezoidal block is snapped into the card slot under the elastic force of the spring, thereby realizing the limitation of the cover plate. The operation is simple, and at this time, the assembly of the overall casing is completed.

[0014] It solves the problem that when assembling and disassembling the cover plate, it is necessary to control four toggle blocks and operate them simultaneously. Moreover, the distance between the four toggle blocks is relatively far, making it difficult to perform synchronous operation with one hand, resulting in inconvenient disassembly.

[0023] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides a computer case convenient for assembly for a computer through improvement. The technical solution of the present utility model is as follows:

[0025] Such as Figures 1 - 5As shown in the figure, a computer case that is easy to assemble for a computer includes two side plates 1 and two side plates 2. The opposite surfaces of the two side plates 1 and the two side plates 2 are respectively rotatably connected to the top plate 4 and the bottom plate 3 through rotating shafts. When the two side plates 1 and the two side plates 2 are folded, they are parallel to the top plate 4 and the bottom plate 3, which can save floor space. Both sides of the top plate 4 are fixedly connected with fixing blocks 24. One side of each of the two fixing blocks 24 is provided with an installation groove 10. The inner walls of the two installation grooves 10 are respectively rotatably connected with gears 22 through damping rotating shafts. By setting the damping rotating shafts, the hovering of the knob 23 can be realized, and the knob 23 can be prevented from driving the gear 22 to rotate self. One end of each of the two damping rotating shafts is fixedly installed with a knob 23. The inner walls of both sides of the installation groove 10 are respectively slidably connected with a rack 20 and a rack 21. The rack 20 and the rack 21 are respectively engaged with the gear 22. One side of the fixing block 24 is provided with two rectangular grooves 11. The inner bottom walls of the two rectangular grooves 11 are provided with sliding grooves 16. By setting the sliding grooves 16, the two spheres 18 can be limited. The inner walls of the two sliding grooves 16 are respectively slidably connected with spheres 18. One end of the rack 20 is fixedly connected with a connecting rod 19. The connecting rod 19 is Z-shaped and can be connected to one of the spheres 18. One ends of the connecting rod 19 and the rack 21 are respectively fixedly connected to the surfaces of the corresponding two spheres 18. Two limiting holes are penetrated through the inner walls of the installation groove 10 and the two rectangular grooves 11. The two limiting holes are respectively slidably connected with the surfaces of the rack 20 and the rack 21. By setting the limiting holes, the rack 20 and the rack 21 can be limited. The opposite surfaces of the rack 20 and the rack 21 are respectively attached to the upper and lower inner walls of the installation groove 10.

[0026] As Figure 2 and Figure 4 shown, in an embodiment, two limiting grooves 9 are commonly opened on the bottom plate 3, the top plate 4, the two side plates 1 and the two side plates 2. By setting the limiting grooves 9, the cover plate 8 can be pre-fixed, and the stability of the cover plate 8 can be improved. The inner walls of the two limiting grooves 9 are respectively slidably connected with a cover plate 8. Two card slots 25 are opened on the opposite surfaces of the two cover plates 8.

[0027] The inner wall of the rectangular groove 11 is fixedly connected with a fixing plate 13. One side of the fixing plate 13 is provided with a sliding hole. The inner wall of the sliding hole is slidably connected with a sliding rod 14. One end of the sliding rod 14 is fixedly connected with a trapezoidal block 12. The surface of the trapezoidal block 12 is adapted to and slidably connected with the inner wall of the card slot 25.

[0028] A spring 17 is sleeved on the surface of the sliding rod 14. The two ends of the spring 17 are respectively fixedly connected with the opposite surfaces of the fixing plate 13 and the trapezoidal block 12. The surface of the trapezoidal block 12 is slidably connected with the inner wall of the rectangular groove 11. One end of the sliding rod 14 away from the trapezoidal block 12 is fixedly connected with a sphere 15. The sliding rod 14 is L-shaped and can cooperate with the sphere 15 to realize the position compensation when being squeezed with the sphere 18.

[0029] As Figure 1 shown, in one embodiment, heat dissipation nets 5 are provided on the surfaces of the top plate 4 and one of the cover plates 8. The heat dissipation nets 5 can prevent external impurities from entering the interior of the casing when the fan dissipates heat. Positioning rods 6 are fixedly connected to one side of each of the two side plates I 1, and positioning cylinders 7 are fixedly connected to one side of each of the two side plates II 2. The surfaces of the two positioning rods 6 are respectively slidably connected to the inner walls of the corresponding two positioning cylinders 7. The positioning rods 6 are inserted into the positioning cylinders 7 to achieve the assembly of the side plates.

[0030] The specific working method is as follows: When using, first rotate the two side plates I 1 and the two side plates II 2 to the vertical position on the top plate 4 and the bottom plate 3 respectively, and then insert the positioning rods 6 into the positioning cylinders 7 to achieve the assembly of the side plates. Then, turn the arc surfaces of the two cover plates 8 downward and insert them into the limiting grooves 9. During the insertion process, the bottom end of the arc first contacts the trapezoidal block 12, which will squeeze the trapezoidal block 12 to retract into the rectangular groove 11. Until the clamping groove 25 formed on the cover plate 8 contacts the trapezoidal block 12, the trapezoidal block 12 is clamped into the clamping groove 25 under the elastic force of the spring 17, thereby realizing the limiting of the cover plate 8. The operation is simple, and at this time, the assembly of the overall casing is completed;

[0031] When disassembling, first disassemble the cover plate 8. By rotating the knob 23, the rotation of the knob 23 drives the rotation of the gear 22. The rotation of the gear 22 can drive the movement of the first rack 20 and the second rack 21 respectively. Thus, the first rack 20 and the second rack 21 drive the two spheres II 18 to move away from each other. Through the design of the sliding groove 16, the movement stability of the two spheres II 18 can be improved. When the two spheres II 18 move away from each other, they can squeeze the movement of the two spheres I 15, thereby driving the sliding rod 14 to slide, realizing the movement of the trapezoidal block 12 to the outside of the clamping groove 25, and realizing the separation of the trapezoidal block 12 from the clamping groove 25. At this time, the cover plate 8 can be pulled out, and the operation is convenient.

[0032] The technical means disclosed in the solution of the present utility model are not limited to the technical means disclosed by the above technical means, but also include the technical solutions composed of equivalent replacements of the above technical features. The matters not covered by the present utility model belong to the common general knowledge of those skilled in the art.
