Description

Technical Field

[0001] This utility model belongs to the field of computer power supply technology, specifically, it relates to a quick-assembly and disassembly computer power supply. Background Technology

[0002] A computer power supply is a device that provides power to a computer. It usually exists in the form of a power supply unit. The power supply unit converts alternating current (AC) to direct current (DC) and transmits the current to various components of the computer system through various cables and plugs. The voltage, power, and current capacity of the power supply are all very important for the performance and reliability of the computer.

[0003] Chinese patent CN222867056U discloses a quick-release computer power supply, including a host casing and a power supply body. The top outer surface of the mounting base has two slots adapted to the mounting feet. A positive and negative lead screw is rotatably connected inside the mounting base. A knob is fixedly connected to the front outer surface of the rotating shaft. A driving bevel gear is fixedly sleeved at the end of the rotating shaft away from the knob. A driven bevel gear is fixedly sleeved on the outer surface of the positive and negative lead screw. Two threaded blocks are threadedly connected to the outer surface of the positive and negative lead screw, and L-shaped blocks are fixedly connected to the top outer surface of each of the two threaded blocks. By setting the positive and negative lead screw and the rotating shaft, and cooperating with the knob, driving bevel gear, and driven bevel gear, the lead screw rotates. The threaded blocks and L-shaped blocks limit the mounting feet at the bottom of the power supply body, thus allowing the computer power supply to be installed and disassembled without the need for specific tools, facilitating assembly and disassembly.

[0004] However, although the aforementioned patent documents describe using lead screws, active bevel gears, and driven bevel gears to drive the L-shaped block to position the power supply body, in actual computer cases, various computer components are installed inside the case, and the space used by the case is relatively small, requiring a certain amount of space for heat dissipation. The aforementioned device is only suitable for use in larger cases, while in actual daily use of computer cases, screws are often used to fix the power supply, which is not suitable for use in everyday computer cases. In view of this, this utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a computer power supply that can be quickly disassembled and assembled, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A quick-release computer power supply, comprising: The chassis has a mounting plate fixed inside, and the power supply unit is mounted on the top side of the mounting plate. The fixing mechanism includes two L-shaped plates and a cover plate. The two L-shaped plates slide and elastically engage with the lower side of the placement plate. The ends of the L-shaped plates are provided with clamping parts. The L-shaped plates are provided with a first extrusion groove. The cover plate is elastically engaged with the upper side of the placement plate. A traction plate is fixed to the lower side of the cover plate. The traction plate slides and engages with the placement plate. The traction plate is provided with a second extrusion groove. The control mechanism includes a mountain-shaped extrusion rod, which is slidably fitted on the lower side of the placement plate and is respectively fitted with the first extrusion groove and the second extrusion groove.

[0007] Optionally, the mountain-shaped extrusion rod includes a first extrusion rod, and second extrusion rods are provided on opposite sides of the first extrusion rod. A positioning element is provided at the end of the first extrusion rod. The positioning element includes a rotating plate rotatably fitted to one end of the first extrusion rod. A limit frame is fixed on one side of the plate, and the rotating plate cooperates with the limit frame. A first inclined surface is provided on one side of both the first extrusion groove and the second extrusion groove. A second inclined surface is provided at one end of both the first extrusion rod and the second extrusion rod, and the first and second inclined surfaces cooperate with each other.

[0008] Optionally, two elastic telescopic rods are fixed to the upper side of the placement plate, and the ends of the two elastic telescopic rods are connected to the cover plate.

[0009] Optionally, the clamping component includes a mounting plate and a positioning plate. The mounting plate is fixed to one end of the L-shaped plate, and the positioning plate is elastically fitted to one side of the mounting plate. A first guide slope is provided on one side of the positioning plate.

[0010] Optionally, an extrusion plate is fixed to the underside of the cover plate, and a second guide slope is provided on one side of the extrusion plate.

[0011] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: The control mechanism allows for control of the movement distance of the mountain-shaped extrusion rod under the placement plate, facilitating the positioning of the power supply unit by the cover plate and clamping components. This makes it easier to assemble and disassemble the power supply unit. With the clamping components and cover plate in place, the power supply unit can be positioned from multiple angles, improving its stability after installation. The first guide ramp allows the power supply unit to displace the extrusion plate during installation, pushing the extrusion plate and reducing movement of the power supply unit. This facilitates initial positioning of the power supply unit, lowers the difficulty of installation, and allows the extrusion plate to accommodate various power supply unit sizes, expanding the applicability of this computer power supply assembly / disassembly equipment.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings.

[0017] Please see Figure 1-4 As shown, this embodiment provides a quick-release computer power supply, including: Chassis 1, a placement plate 101 is fixed inside the chassis 1, and a power supply body 102 is installed on the upper side of the placement plate 101. The fixing mechanism 2 includes two L-shaped plates 201 and a cover plate 202. The two L-shaped plates 201 are slidably and elastically engaged with the lower side of the placement plate 101. The ends of the L-shaped plates 201 are provided with clamping members 6. The L-shaped plates 201 are provided with a first extrusion groove 204. The cover plate 202 is elastically engaged with the upper side of the placement plate 101. The lower side of the cover plate 202 is fixed with a traction plate 203. The traction plate 203 is slidably engaged with the placement plate 101. The traction plate 203 is provided with a second extrusion groove 205. The control mechanism 3 includes a mountain-shaped extrusion rod 301, which is slidably fitted on the lower side of the placement plate 101. The mountain-shaped extrusion rod 301 is respectively fitted with the first extrusion groove 204 and the second extrusion groove 205.

[0018] When the power supply unit 102 of the computer needs to be disassembled, first control the movement of the mountain-shaped pressing rod 301. During the movement, the mountain-shaped pressing rod 301 will move out of the first pressing groove 204 on the L-shaped plate 201 and the second pressing groove 205 on the traction plate 203 respectively, thereby stopping the positioning of the L-shaped plate 201 and the traction plate 203. At this time, the clamping piece 6 at one end of the placement plate 101 and the L-shaped plate 201 will move away from the power supply unit 102 under the action of the elastic force (because the two L-shaped plates 201 slide and are elastically engaged on the lower side of the placement plate 101, and the cover plate 202 is elastically engaged on the upper side of the placement plate 101). Then, simply remove the power supply unit 102 that needs to be disassembled. When the power supply unit 102 of the computer needs to be installed, the power supply unit 102 is first placed in the placement plate 101. Then, the mountain-shaped extrusion rod 301 is driven to extrude the first extrusion groove 204 on the L-shaped plate 201 and the second extrusion groove 205 on the traction plate 203. With the first extrusion groove 204 and the second extrusion groove 205 set, the clamping member 6 at one end of the L-shaped plate 201 and the traction plate 203 can respectively extrude the power supply unit 102, thereby facilitating the positioning of the power supply unit 102.

[0019] The control mechanism 3 controls the movement distance of the mountain-shaped extrusion rod 301 below the placement plate 101, thus facilitating the positioning of the cover plate 202 and the clamping member 6 on the power supply body 102. This makes it easier to assemble and disassemble the power supply body 102. With the clamping member 6 and the cover plate 202, the power supply body 102 can be positioned from multiple angles, thereby improving the stability of the power supply body 102 after installation. Through the first guide slope, when the power supply body 102 is installed, it can displace the extrusion plate 7 under the extrusion of the first guide slope, thereby pushing the extrusion plate 7 to move and reducing the movement of the power supply body 102. This facilitates the initial positioning of the power supply body 102, reduces the difficulty of the installation operation of the power supply body 102, and the extrusion plate 7 can also adapt to the installation of power supply bodies 102 of various specifications, thus improving the applicability of this computer power supply assembly and disassembly equipment.

[0020] The mountain-shaped extrusion rod 301 of this embodiment includes a first extrusion rod 302, and second extrusion rods 303 are provided on both opposite sides of the first extrusion rod 302. A positioning member 4 is provided at the end of the first extrusion rod 302. The positioning member 4 of this embodiment includes a rotating plate 401 rotatably engaged with one end of the first extrusion rod 302. A limiting frame 402 is fixed on one side of the placement plate 101, and the rotating plate 401 cooperates with the limiting frame 402. The first extrusion groove 204 and the second extrusion groove 205 of this embodiment are each provided with a first inclined surface on one side, and the first extrusion rod 302 and the second extrusion rod 303 are each provided with a second inclined surface at one end. The first inclined surface and the second inclined surface cooperate with each other. Specifically, one side of both the first extrusion groove 204 and the second extrusion groove 205 is a sloping structure, and the orientation of the sloping surfaces corresponds to the first inclined surface and the second inclined surface. Through the first inclined surface and the second inclined surface, when the control rotating plate 401 drives the first extrusion rod 302 to move, the first inclined surface on the first extrusion rod 302 and the second extrusion rod 303 will press against each other with the first inclined surface on the first extrusion groove 204 and the second extrusion groove 205. Under the mutual pressing of the two inclined surfaces, the traction plate 203 can be driven to move towards the placement plate 101, thereby driving the cover plate 202 to press against the placed power supply body 102. While the cover plate 202 moves, the L-shaped plate 201 will drive the clamping member 6 to move towards the power supply body 102, thereby completing the positioning of the top and two sides of the power supply body 102 and improving the stability of the power supply body 102 on the placement plate 102. Furthermore, with the setting of the limiting frame 402, after the first pressing rod 302 moves to the predetermined position, the rotating plate 401 can be rotated into the limiting frame 402, thereby positioning the moved cover plate 202 and the clamping part 6. Without the need for tools, the staff can complete the disassembly and assembly of the power supply body 102, which improves the convenience of disassembly and assembly of the power supply body 102.

[0021] In this embodiment, two guide frames are fixed on the lower side of the placement plate 101. The L-shaped plate 201 is slidably fitted in the guide frame, and a spring is installed at one end of the L-shaped plate 201. A fixing block is installed on the lower side of the placement plate 101, and a spring is fixed between the fixing block and the end of the L-shaped plate 201. Through the spring, when the mountain-shaped pressing rod 301 releases the positioning of the power supply body 102, the second pressing rod 303 will release the control of the L-shaped plate 201. At this time, the L-shaped plate 201 will move in the opposite direction of the power supply body 102 under the elastic force of the spring, thereby driving the L-shaped plate 201 to return to the initial position, which facilitates the connection between the L-shaped plate 201 and the second pressing rod 303 when the power supply body 102 is installed next time.

[0022] In this embodiment, two elastic telescopic rods 5 are fixed to the upper side of the placement plate 101, and the ends of the two elastic telescopic rods 5 are connected to the cover plate 202. With the two elastic telescopic rods 5, when the first pressing rod 302 releases its restriction on the cover plate 202, the cover plate 202 can be reset under the elastic force of the elastic telescopic rods 5 themselves, thereby facilitating the removal of the power supply body 102 after it has been released from its positioning, and further improving the disassembly of the power supply body 102.

[0023] The clamping member 6 in this embodiment includes a mounting plate 601 and a positioning plate 602. The mounting plate 601 is fixed to one end of the L-shaped plate 201, and the positioning plate 602 is elastically fitted to one side of the mounting plate 601. A first guide slope 603 is provided on one side of the positioning plate 602 in this embodiment. Through the first guide slope 603, when the power supply body 102 needs to be installed, it is only necessary to pick up the power supply body 102 and press it into the placement plate 101. During the pressing process, the two sides of the power supply body 102 will first contact the two sides of the positioning plate 602, and during the contact process, the positioning plate 602 will be pressed, causing the positioning plate 602 to move towards the mounting plate 601. When the power supply body 102 moves to the predetermined installation position, the positioning plate 602 will press against the power supply body 102 under the action of elasticity, thereby completing a preliminary positioning of the power supply body 102, and also enabling the positioning of power supply bodies 102 of various specifications.

[0024] In this embodiment, a pressing plate 7 is fixed to the lower side of the cover plate 202, and a second guide slope 701 is provided on one side of the pressing plate 7. Through the provided second guide slope 701, when the power supply body 102 is installed, the upper part of the power supply body 102 will press against the second guide slope 701, and during the pressing process, it can drive the cover plate 202 to move upward. This not only facilitates the installation of the power supply body 102, but also adapts to the installation of different power supply bodies 102 in various specifications, and also facilitates the operation of the staff.

[0025] In this embodiment, the placement plate 101 is provided with a placement groove, in which a ventilation filter plate is installed. Multiple abutment seats are provided on the upper side of the ventilation filter plate. The ventilation filter plate not only positions the power supply body 102 but also facilitates heat dissipation. Furthermore, the abutment seats create a gap between the installed power supply body 102 and the abutment seats, allowing for airflow and further improving the heat dissipation efficiency of the power supply body 102.

[0026] Multiple limiting frames 402 can be provided in this embodiment; they enable the rotating plate 401 to control the moving distance of the first pressing rod 302, thereby facilitating the positioning of power supply bodies 102 of various specifications.
