The applicability of screws in the structure is also limited. Additional space or tools are required to install and remove screws. In addition, there are disadvantages such as low connection strength, poor durability and difficulty in disassembly. Therefore, an easy-to-assemble power supply housing is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an easily assembled power supply housing, comprising a housing, an external fixing device for the housing, the fixing device comprising two fixing blocks and a top cover, the two fixing blocks being fixedly connected to the housing on their adjacent sides, the top cover having two slots on one side, an internal threaded ring being fixedly connected to the inner side of the fixing blocks, a bolt being threaded into the inner thread of the internal threaded ring, an L-shaped block being slidably connected to the arc surface of the bolt, and a snap-fit ​​plate being fixedly connected to the adjacent ends of the two L-shaped blocks, the outer side of the snap-fit ​​plate being adapted to the slot.

[0006] The effect achieved by the above components is as follows: the bolt rotation is eliminated and the internal threaded ring is assembled. After the bolt is completely disengaged from the internal threaded ring, the limit on the L-shaped block is eliminated. The L-shaped block moves away from the slot, which drives the snap-fit ​​plate to eliminate the limit on the top cover, thus completing the assembly between the top cover and the shell.

[0021] Preferably, heat dissipation fins are fixedly connected to one side of the two connecting plates.

[0022] The effect achieved by the above components is that the heat dissipation fins are fixed to the connecting plate.

[0023] In summary, the beneficial effects of this utility model are as follows:

[0024] In this utility model, by means of a fixing device, when it is necessary to assemble or disassemble the power supply casing, the bolts and internal threaded rings are removed to eliminate the limitation on the L-shaped block, so that the snap-fit ​​plate can be moved away from the slot to eliminate the limitation on the top cover. By means of a fixing device, the problem of traditional easy-to-assemble power supply casings being assembled by screws is solved. The applicability of screw assembly in the structure is also limited, requiring additional space or tools to install and remove screws, and there are disadvantages such as low connection strength, poor durability, and difficulty in disassembly.

[0025] In this invention, when it is necessary to enhance the heat dissipation performance of the power supply casing, the operator first assembles the assembly rod and the slide groove.

Through the heat dissipation device, the problem of poor heat dissipation effect of traditional easily assembled power supply casings is solved. Attached Figure Description

[0032] Reference Figure 1 As shown, this utility model provides a technical solution: an easily assembled power supply housing, including a housing 1, a fixing device 2 on the outside of the housing 1, and a heat dissipation device 3 on the outside of the housing 1.

[0033] The following section will describe the specific setup and function of its fixing device 2 and heat dissipation device 3.

[0034] Reference Figure 2 , Figure 3 and Figure 5 As shown in this embodiment: the fixing device 2 includes two fixing blocks 207 and a top cover 201. The two fixing blocks 207 are fixedly connected to the housing 1 on their adjacent sides. Two slots 202 are provided on one side of the top cover 201. An internal threaded ring 206 is fixedly connected to the inner side of the fixing blocks 207. A bolt 205 is connected to the internal thread of the internal threaded ring 206. An L-shaped block 204 is slidably connected to the arc surface of the bolt 205. A snap-fit ​​plate 203 is fixedly connected to the adjacent ends of the two L-shaped blocks 204. The outer side of the snap-fit ​​plate 203 is adapted to the slot 202. This achieves the elimination of bolt 205 rotation and the assembly between the internal threaded ring 206. After the bolt 205 is completely disengaged from the internal threaded ring 206, the limiting effect on the L-shaped block 204 is eliminated. The L-shaped block 204 moves away from the slot 202, causing the snap-fit ​​plate 203 to eliminate the limiting effect on the top cover 201, thus completing the assembly effect between the top cover 201 and the housing 1. Two T-shaped grooves 209 are formed on one side of the top cover 201, and a T-shaped rubber block 210 is slidably connected inside the T-shaped grooves 209. This achieves the effect of the T-shaped rubber block 210 sliding within the T-shaped grooves 209. A limiting plate 211 is fixedly connected to one side of the T-shaped rubber block 210. This achieves the effect of the limiting plate 211 moving, causing the T-shaped rubber block 210 to move. A concave guide plate 208 is fixedly connected to one side of the fixing block 207, and the inner side of the concave guide plate 208 is slidably connected to the L-shaped block 204. This achieves the effect of the concave guide plate 208 preventing the L-shaped block 204 from shifting position during assembly.

[0035] Reference Figure 4 As shown in this embodiment: the heat dissipation device 3 includes two square rods 31. The sides of the two square rods 31 that are close to each other are fixedly connected to the housing 1. A groove 32 is provided on one side of each square rod 31. This achieves the effect of the groove 32 being formed on the square rod 31. An assembly rod 33, made of rubber, is slidably connected inside the groove 32. This achieves the effect of the assembly rod 33 and the groove 32 being compatible. A connecting plate 34 is fixedly connected to one side of the assembly rod 33. This achieves the effect of the connecting plate 34 moving to drive the assembly rod 33 to move. A force-bearing block 35, made of rubber, is fixedly connected to the sides of the two connecting plates 34 that are far apart from each other. This achieves the effect of the force-bearing block 35 being fixed to the connecting plate 34, and the force-bearing block 35 driving the connecting plate 34 to move when subjected to force. Heat dissipation fins 36 are fixedly connected to one side of the two connecting plates 34. This achieves the effect of the heat dissipation fins 36 being fixed to the connecting plate 34.

[0036] Working principle: When the power supply casing needs to be assembled or disassembled via the fixing device 2, the operator first moves the limiting plate 211 away from the snap-fit ​​plate 203. The limiting plate 211 causes the T-shaped rubber block 210 to slide within the T-shaped groove 209 until the limiting plate 211 moves to eliminate its restriction on the snap-fit ​​plate 203. Then, the bolt 205 can be rotated to disassemble the bolt 205 from the internal threaded ring 206. After the bolt 205 is completely disengaged from the internal threaded ring 206, its restriction on the L-shaped block 204 is eliminated. After the restriction on the L-shaped block 204 is eliminated, the L-shaped block is pulled away from the top cover 201. 204. The L-shaped block 204 is driven by force to move the snap-fit ​​plate 203 away from the slot 202 until it is completely separated from the slot 202. This eliminates the restriction on the top cover 201, thus completing the disassembly between the top cover 201 and the housing 1. When reassembly is required, the reverse steps are repeated. The fixing device 2 solves the problem that traditional easy-to-assemble power supply housings are basically assembled with screws. The applicability of screws in the structure is also limited. Additional space or tools are required to install and remove screws, and there are disadvantages such as low connection strength, poor durability, and difficulty in disassembly.

[0037] When it is necessary to enhance the heat dissipation performance of the power supply casing, the operator first assembles the assembly rod 33 and the slide groove 32. After the assembly rod 33 and the slide groove 32 are assembled, the connecting plate 34 drives the heat dissipation fins 36 to contact the casing 1, thereby transferring the heat inside the casing 1 to the heat dissipation fins 36 for heat dissipation. Through the heat dissipation device 3, the problem of poor heat dissipation effect of traditional easily assembled power supply casings is solved.
