Description

Technical Field

[0001] This utility model relates to the field of power supply protection technology, specifically to an external frame protection device for a power supply. Background Technology

[0002] As a crucial component of electronic devices, the safety and stability of power supplies directly affect the overall performance of the equipment. Especially in complex and ever-changing operating environments, power supplies are susceptible to corrosion and damage from external factors, which can affect their normal operation. To mitigate this issue, developing an external structural protection device for power supplies is of paramount importance.

[0003] According to CN219780671U, a power supply external frame protection device includes a lower frame, with a power supply fixedly connected to the bottom of the inner wall of the lower frame, and an upper frame mounted on top of the lower frame. When the upper frame is subjected to external pressure, it moves downwards, causing a second transmission plate to move downwards. The second transmission plate rotates in conjunction with a first transmission plate, pushing a telescopic push plate inwards. Simultaneously, the telescopic push plate retracts, compressing a spring inwards. When the spring is compressed, the pressure on the upper frame is relieved. When the upper frame is relieved of some of the pressure, it will not be easily crushed, and the protection effect of the power supply is significantly improved. It has the advantage of anti-compression buffer. The outer frame has the effect of stress relief and buffer. When the outer frame is squeezed by foreign objects, it will not easily deform, which can play a good protective role and improve the safety of power supply use. As can be seen from the above, although this device can be well applied, it is usually not convenient to perform heat dissipation work on the outer frame of the power supply. This makes the power supply components inside the outer frame prone to burnout due to high temperature, which often troubles users. Utility Model Content

[0004] The purpose of this utility model is to provide a power supply external frame protection device to solve the problem that although the device proposed in the background art can be applied well, it is usually not convenient to perform heat dissipation work on the power supply external frame, which makes the power supply components inside the external frame prone to burn-out due to high temperature.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power supply external frame protection device, comprising a protective shell, a first side shell cover installed on one side of the outer wall of the protective shell, a second side shell cover installed on the outer wall of the protective shell away from the first side shell cover, a limiting frame provided at the center of the bottom of the protective shell, a power supply external frame inserted and installed inside the bottom of the protective shell on the inner side of the limiting frame, a pressure head provided inside the protective shell above the power supply external frame, a lifting plate installed at the top of the pressure head, heat dissipation fins provided at the top of the protective shell, the bottom end of the heat dissipation fins extending into the interior of the protective shell, a fan frame bolted to the top of the heat dissipation fins, and a fan installed inside the fan frame.

[0006] Preferably, a first locking bolt is installed at the corner position of the outer wall of the first side cover. One end of the first locking bolt passes through the first side cover and is threadedly connected to the outer wall of the protective shell. The first locking bolt is used to install the first side cover on one side of the outer wall of the protective shell.

[0007] Preferably, a second locking bolt is installed at the corner position of the outer wall of the second side cover. One end of the second locking bolt passes through the second side cover and is threadedly connected to the outer wall of the protective shell. The second locking bolt is used to install the second side cover on one side of the outer wall of the protective shell.

[0008] Preferably, positioning seats are provided on both sides inside the lifting plate, and both ends of the positioning seats extend to the outside of the lifting plate. The positioning seats are provided to accommodate the threaded cylinder.

[0009] Preferably, the positioning seat is provided with a threaded cylinder inside, and both ends of the threaded cylinder extend to the outside of the positioning seat. By setting the threaded cylinder on the outer wall of the threaded rod, the height of the pressure head can be adjusted up and down.

[0010] Preferably, the threaded cylinder has a threaded rod installed on its internal threads. The top end of the threaded rod extends to the outside of the threaded cylinder and is rotatably connected to the bottom end of the heat dissipation fins. The bottom end of the threaded rod extends to the outside of the threaded cylinder and is equipped with a handle. By rotating the handle, the threaded rod can be driven to rotate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the external frame protection device of the power supply not only reduces the phenomenon of power components inside the power supply external frame being burned due to high temperature, but also improves the convenience of power supply external frame installation, and ensures the protective effect of the protection device on the power supply external frame when in use.

[0012] (1) The heat sink extends to the inside of the protective shell through the lower end of the heat sink fins. When the power supply external frame generates heat during operation, the heat sink fins will absorb and conduct the heat energy inside the protective shell. The fan inside the fan frame will accelerate the heat conduction efficiency of the heat sink fins to achieve the purpose of heat dissipation and cooling of the power supply external frame, thereby reducing the phenomenon of power components inside the power supply external frame being burned due to high temperature.

[0013] (2) By rotating the two handles synchronously, the threaded rod at the bottom of the heat sink fins is rotated. At this time, the two threaded cylinders slide down the outer wall of the threaded rod, so that the pressure head moves down through the lifting plate and fits against the top of the lifting plate. The pressure head can then press the power supply frame down and place it at the bottom of the protective shell. The limit frame limits the lower end of the power supply frame, thereby improving the convenience of power supply frame installation.

[0014] (3) By tightening the first locking bolt and the second locking bolt, one end of which passes through the first side cover and the second side cover respectively and is screwed into the outer wall of the protective shell, the first side cover and the second side cover can be installed on the outer walls of both sides of the protective shell, so that the protective shell, together with the first side cover and the second side cover, can provide a closed protection for the power supply frame, thereby ensuring the protection effect of the protective device on the power supply frame when in use.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1-4 An embodiment of this utility model is provided: an external frame protection device for a power supply, including a protective shell 1, a first side shell cover 2 installed on the outer wall of one side of the protective shell 1, and a first locking bolt 201 installed at the corner of the outer wall of the first side shell cover 2. One end of the first locking bolt 201 passes through the first side shell cover 2 and is threadedly connected to the outer wall of the protective shell 1.

[0022] In use, the first locking bolt 201 is used to install the first side cover 2 onto one side outer wall of the protective shell 1;

[0023] A second side cover 3 is installed on the outer wall of the protective shell 1 on the side away from the first side cover 2. A second locking bolt 301 is installed at the corner of the outer wall of the second side cover 3. One end of the second locking bolt 301 passes through the second side cover 3 and is threadedly connected to the outer wall of the protective shell 1.

[0024] In use, the second locking bolt 301 is used to install the second side cover 3 onto one side outer wall of the protective shell 1;

[0025] A limiting frame 7 is provided at the center of the bottom of the protective shell 1. A power supply external frame 8 is inserted and installed on the bottom of the protective shell 1 inside the limiting frame 7. A pressure head 10 is provided inside the protective shell 1 above the power supply external frame 8. A lifting plate 9 is installed on the top of the pressure head 10. Positioning seats 11 are provided on both sides inside the lifting plate 9. Both ends of the positioning seats 11 extend to the outside of the lifting plate 9.

[0026] In use, the positioning seat 11 is set to place the threaded cylinder 12.

[0027] The positioning seat 11 is provided with a threaded cylinder 12 inside, and both ends of the threaded cylinder 12 extend to the outside of the positioning seat 11.

[0028] In use, the threaded cylinder 12 is placed on the outer wall of the threaded rod 13 so that the height of the pressure head 10 can be adjusted up and down;

[0029] The threaded cylinder 12 has a threaded rod 13 installed inside its internal threads. The top end of the threaded rod 13 extends to the outside of the threaded cylinder 12 and is rotatably connected to the bottom end of the heat dissipation fins 4. The bottom end of the threaded rod 13 extends to the outside of the threaded cylinder 12 and is fitted with a handle 14.

[0030] In use, the screw handle 14 is turned to drive the threaded rod 13 to rotate;

[0031] The top of the protective shell 1 is provided with heat dissipation fins 4, the bottom of the heat dissipation fins 4 extends into the interior of the protective shell 1, and the top of the heat dissipation fins 4 is bolted with a fan frame 5, and a fan 6 is installed inside the fan frame 5.

[0032] In this embodiment, during use, the two handles 14 are rotated synchronously to rotate the threaded rod 13 at the bottom of the heat sink fins 4. At this time, the two threaded cylinders 12 slide downwards on the outer wall of the threaded rod 13, causing the pressure head 10 to move downwards via the lifting plate 9 and adhere to the top of the lifting plate 9. The pressure head 10 then presses the power supply outer frame 8 down and places it at the bottom of the protective shell 1. The limiting frame 7 limits the lower end of the power supply outer frame 8, improving the ease of installation. If the pressure head 10 is moved upwards away from the power supply outer frame 8, and the power supply outer frame 8 is pulled upwards, the lower end of the power supply outer frame 8 is detached from the limiting frame 7, allowing for disassembly and maintenance of the power supply outer frame 8. Afterwards, by tightening... By moving the first locking bolt 201 and the second locking bolt 301, one end of which passes through the first side cover 2 and the second side cover 3 respectively and is screwed into the outer wall of the protective shell 1, the first side cover 2 and the second side cover 3 can be installed on the two outer walls of the protective shell 1. This allows the protective shell 1, together with the first side cover 2 and the second side cover 3, to provide a closed protection for the power supply external frame 8. Finally, the heat dissipation fins 4 extend into the interior of the protective shell 1 through their lower ends. When the power supply external frame 8 generates heat during operation, the heat dissipation fins 4 absorb and conduct the heat from the interior of the protective shell 1. The fan 6 inside the fan frame 5 accelerates the heat conduction efficiency of the heat dissipation fins 4 to cool down the power supply external frame 8, thus completing the use of the protection device.
