Description

Technical Field

[0001] The utility model relates to the technical field of computers, and more specifically to a computer power supply component. Background Art

[0002] Computers are low-voltage products, which means that the operating voltage of their components is relatively low, generally within plus or minus 12 volts, and is direct current. Ordinary AC power is 220 volts, which cannot be used directly on computer components. Therefore, computers require a power supply part, which is responsible for converting ordinary AC power into a voltage that can be used by the computer. Its essence is a small transformer.

[0003] The computer power supply is usually fixed directly in the chassis by multiple screws. During use, dust and foreign matter will accumulate on the heat dissipation port and cooling fan of the power supply, which need to be cleaned regularly. The most direct way to clean it is to remove the entire power supply from the chassis. Due to the small internal space of the chassis, it is very time-consuming and laborious for the staff to remove the screws that fix the power supply, which affects the cleaning efficiency and increases the workload of the workers.

[0004] In view of this, we propose a computer power supply assembly. Utility Model Content

[0028] See also Figure 1-5 , the utility model provides a technical solution:

[0029] A computer power supply assembly includes a case 1 and a power supply body 2. A fixing frame 3 is fixedly arranged inside the case 1, a mounting frame 4 is movably arranged inside the fixing frame 3, the power supply body 2 is movably installed inside the mounting frame 4, two sets of fixing plates 5 are fixedly arranged on the upper side of the fixing frame 3, a threaded rod 6 is rotatably arranged on the lower side of one set of fixing plates 5, a movable block 7 is threadedly sleeved on the outer side of the threaded rod 6, a limit block 8 is fixedly arranged on the lower side of the movable block 7, and a gear 10 is fixedly sleeved on the outer side of the threaded rod 6, a toothed plate 9 is fixedly arranged on the outer side of the mounting frame 4, and the toothed plate 9 is meshed with the toothed plate 9. On the gear 10, a positioning mechanism for docking with the mounting frame 4 is provided on the inner side of the fixing frame 3. When the mounting frame 4 is pulled toward the outside of the fixing frame 3, the movable block 7 and the limit block 8 can be driven to move upward, thereby facilitating the removal of the power supply body 2 from the mounting frame 4 for cleaning. When the inner side of the fixing frame 3 in the mounting frame 4 is pushed, the movable block 7 and the limit block 8 can be driven to move downward, thereby limiting and fixing the power supply body 2, facilitating the installation and fixing of the power supply body 2. The use is very flexible and convenient, and the convenience of loading and unloading the power supply body 2 is improved.

[0030] Specifically, the positioning mechanism includes a fixed block 11 fixedly arranged on the inner side of the fixed frame 3, a positioning rod 12 is movably arranged on one side of the fixed block 11, a connecting plate 13 is fixedly arranged on the outer end of the positioning rod 12, and the other end of the positioning rod 12 movably passes through the fixed block 11 and extends to the other side, a positioning hole 15 for docking with the positioning rod 12 is arranged on the outer side of the installation frame 4, and the positioning rod 12 is movably inserted into the positioning hole 15, which facilitates the movement of the installation frame 4 while ensuring the stability of the installation frame 4.

[0031] Furthermore, a pull ring 14 is fixedly provided on the outer side of the connection disk 13. The pull ring 14 can be provided to facilitate pulling the connection disk 13 and the positioning rod 12, thereby improving the convenience of use.

[0032] It is worth noting that a reset spring 16 is sleeved on the outer side of the positioning rod 12, one end of the reset spring 16 is connected to the connecting plate 13, and the other end of the reset spring 16 is connected to the fixed block 11. The reset spring 16 does not deform in the initial state. When the connecting plate 13 is pulled to drive the positioning rod 12 to move, the connecting plate 13 stretches the reset spring 16, and the reset spring 16 deforms at this time. When the pull ring 14 is released, the elastic potential energy of the reset spring 16 is released, so that the positioning rod 12 can be quickly inserted into the positioning hole 15, which improves the convenience and stability of plugging.

[0033] It is worth noting that a slide rod 17 is fixedly provided on the lower side of another set of fixed plates 5. The slide rod 17 is movable and runs through the movable block 7. The slide rod 17 can limit the movable block 7, so that when the threaded rod 6 rotates, it can drive the movable block 7 to move vertically up and down, thereby facilitating the limit block 8 to limit and fix the power supply body 2.

[0034] In addition, a connecting rod 18 is fixedly provided on the lower side of the installation frame 4, and a cross-shaped block 19 is fixedly provided on the lower end of the connecting rod 18. A cross-shaped groove 20 for docking with the cross-shaped block 19 is opened on the inner side of the fixing frame 3. When the installation frame 4 moves, it drives the cross-shaped block 19 to slide within the cross-shaped groove 20 within a limited position, thereby facilitating the movement of the installation frame 4 while further ensuring the stability of the installation frame 4, thereby improving the stability of the power supply body 2.

[0035] It must be mentioned that a handle 21 is fixedly provided on the outside of the installation frame 4. The handle 21 can be conveniently provided to push and pull the installation frame 4, thereby further improving the convenience of operation.

[0036] Working principle: First, when installing the power supply body 1, place the power supply body 1 in the installation frame 4, and then push the installation frame 4 into the inner side of the fixing frame 3. When the installation frame 4 moves, it drives the tooth plate 9 to move, and when the gear 9 moves, it drives the gear 10 to rotate, and when the gear 10 rotates, it drives the threaded rod 6 to rotate. At this time, the movable block 7 sleeved on the outer side of the threaded rod 6 moves vertically downward along the threaded rod 6 under the limiting action of the slide rod 17. When the movable block 7 moves downward, it drives the limit block 8 to move downward. When the installation frame 4 is completely moved to the inner side of the fixing frame 3, the limit block 8 just contacts the power supply body. The power supply body 2 is convenient and quick to install. When the power supply body 2 needs to be cleaned, the pull ring 14 is first pulled outward to drive the connecting plate 13 and the positioning rod 12 to move. The connecting plate 13 drives the positioning rod 12 to move out of the positioning hole 15 and stretch the reset spring 16. Then, the mounting frame 4 is pulled toward the outside of the fixing frame 3 through the handle 21. When the mounting frame 4 moves, it drives the tooth plate 9 to move, and when the gear 9 moves, it drives the gear 10 to rotate. The same principle can drive the movable block 7 and the limit block 8 to move upward, so that the power supply body 2 can be quickly disassembled and cleaned, thereby improving the convenience of use.
