Description

Technical Field

[0001] This utility model relates to the technical field of heat sink fixing structure, specifically to a chassis heat sink fixing bracket. Background Technology

[0002] Heat sinks are devices used to reduce the temperature of chips. They can draw out and dissipate the heat on the chip, thereby reducing the high temperature generated during chip operation and avoiding instability caused by high temperature. It is also one of the main heat dissipation methods for chips today.

[0003] Current heatsinks are typically attached to the motherboard with screws, which also attach the heatsink to the chip. Since the heatsink and mounting bracket are usually an integrated structure, when the heatsink is damaged, it needs to be removed along with the mounting bracket before a new heatsink can be installed. Due to limited space, this process is cumbersome and increases costs. Therefore, a chassis heatsink mounting bracket is proposed here. Utility Model Content

[0004] The technical solution adopted by this utility model to solve the technical problem is: a chassis heat sink fixing bracket, including a frame, an extension plate fixedly connected to the upper edge of one end of the frame, front baffles fixedly connected to the opposite side walls of the frame, a slot opened in the middle of one side wall of the front baffle, a sealing plate rotatably connected to the lower edge of the end of the frame away from the extension plate, a knob rotatably connected to the side wall of the sealing plate away from the frame, a linkage plate fixedly connected to one end of the knob, a locking groove opened in the bottom side wall of the extension plate, and the linkage plate rotatably inserted into the locking groove.

[0005] As a preferred technical solution of this utility model, a top plate is fixedly connected to one side wall of the sealing plate, the top plate being an elastic rubber pad; a pressing block is fixedly connected to one side wall of the linkage plate, the pressing block having a trapezoidal structure; and a top support plate is fixedly connected to one side wall of the locking groove, the top support plate and the pressing block having corresponding trapezoidal structures.

[0006] As a preferred technical solution of this utility model, a movable groove is provided in one end of the top support plate, and four springs are fixedly connected to one side wall of the movable groove. One end of each spring is fixedly connected to a limit block, and a positioning groove is provided on the side wall of the extrusion block opposite to the movable groove.

[0007] As a preferred embodiment of this utility model, the limiting block is inserted into the positioning groove, the two side walls of the positioning groove are inclined, and the end of the limiting block away from the spring is tapered.

[0008] As a preferred technical solution of this utility model, a heat sink is provided on one side of the frame, and a rear upright plate is fixedly connected to the two opposite edges of the heat sink. An insert plate is fixedly connected to one side wall of the rear upright plate. The heat sink is inserted into the slot through the insert plate, and the heat sink and the slot have a conical structure. An anti-slip pad is fixedly connected to the inner wall of the slot. Mounting holes are opened through the four corners of the frame, and screws are inserted into the mounting holes.

[0009] This utility model has the following advantages: A front baffle is connected inside the frame and a slot is opened on it. The insert plate is aligned with the slot, and then the insert plate is pushed into the slot to connect the heat sink into the frame. Then the sealing plate is closed. The top plate can compress the heat sink, improving the stability after connection. By rotating the knob, the linkage plate and the compression block rotate synchronously, moving the compression block into the locking groove. The interaction between the compression block and the top support plate firmly closes the sealing plate to the frame. At the same time, the force generated by the compression block and the top support plate makes the top plate fit more tightly to the heat sink. When disassembling, simply flip the knob and then lift the sealing plate. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Please refer to the following: Figure 1-3This utility model discloses a chassis heat sink fixing bracket, including a frame 1. An extension plate 2 is fixedly connected to the upper edge of one end of the frame 1. Front baffles 3 are fixedly connected to the opposite side walls of the frame 1. A slot 12 is opened in the middle of one side wall of the front baffle 3. A sealing plate 4 is rotatably connected to the lower edge of the end of the frame 1 away from the extension plate 2. A knob 6 is rotatably connected to the side wall of the end of the sealing plate 4 away from the frame 1. A linkage plate 7 is fixedly connected to one end of the knob 6. A locking groove 13 is opened in the bottom side wall of the extension plate 2. The linkage plate 7 is rotatably inserted into the locking groove 13.

[0016] A top plate 5 is fixedly connected to one side wall of the sealing plate 4. The top plate 5 is an elastic rubber pad. A pressing block 8 is fixedly connected to one side wall of the linkage plate 7. The pressing block 8 has a trapezoidal structure. A top support plate 14 is fixedly connected to one side wall of the locking groove 13. The top support plate 14 and the pressing block 8 have corresponding trapezoidal structures. A movable groove is provided in one end of the top support plate 14. Four springs 15 are fixedly connected to one side wall of the movable groove. A limit block 16 is fixedly connected to one end of the springs 15. A positioning groove 17 is opened on the side wall of the pressing block 8 opposite to the movable groove. The limit block 16 is inserted into the positioning groove 17. The two side walls of the positioning groove 17 are inclined structures. The end of the limit block 16 away from the spring 15 is a conical structure.

[0017] The technical effect of this solution is as follows: the heat sink 9 is connected into the frame 1, and then the sealing plate 4 is closed on the frame 1. After closing, the knob 6 is rotated, and the rotation of the knob 6 drives the linkage plate 7 and the pressing block 8 to move, thereby sending them into the locking groove 13. As the linkage plate 7 and the pressing block 8 move, they will move in contact with the top support plate 14, thus generating an interaction force. The tension generated by the interaction can stably close the sealing plate 4 on the frame 1, while pulling the top plate 5 to press the heat sink 9, improving the stability of the connection of the heat sink 9. When disassembling, it is only necessary to rotate the knob 6 in the opposite direction to remove the linkage plate 7 and the pressing block 8 from the locking groove 13, and then lift the sealing plate 4, and then pull the heat sink 9 out of the frame 1 for replacement. It is not necessary to remove all components, and it is not affected by the small space problem, thus improving the convenience of disassembly and assembly.

[0018] A heat sink 9 is provided on one side of the frame 1. The two ends of the heat sink 9 that are far apart from each other are fixedly connected to a rear upright plate 10. A plug plate 11 is fixedly connected to one side wall of the rear upright plate 10. The heat sink 9 is inserted into the slot 12 through the plug plate 11. The heat sink 9 and the slot 12 are of a conical structure. An anti-slip pad is fixedly connected to the inner wall of the slot 12. Mounting holes are opened through the four corners of the frame 1, and screws are inserted into the mounting holes.

[0019] The technical effect of this solution is as follows: Align the insert plate 11 with the slot 12, and then push the heat sink 9 to insert the insert plate 11 into the slot 12. As it is pushed in, the heat sink 9 is fully inserted into the frame 1. The front baffle 3 allows the back of the heat sink 9 to be fully exposed and on the same plane as the outer wall of the frame 1. This avoids the heat sink 9 not being tightly attached to the chip due to installation height difference, which would affect the heat dissipation effect.

[0020] Specifically, in use, the frame 1 is mounted on the motherboard using screws through the mounting holes. When the heatsink 9 needs to be replaced, the knob 6 is rotated in the opposite direction. As the knob 6 is rotated, the pressing block 8 and the linkage plate 7 are moved out of the locking groove 13. Then, the sealing plate 4 is pulled outwards and opened, and the heatsink 9 is then pulled out of the frame 1. The new heatsink 9 is then inserted into the slot 12 through the insert plate 11, thus installing the heatsink 9 into the frame 1. After installation, the sealing plate 4 is closed, and then the knob 6 is rotated to insert the linkage plate 7 and the pressing block 8 into the locking groove 13. As the pressing block 8 and the top support plate 14 adhere and penetrate deeper, the heatsink 9 can be installed into the frame 1. The sealing plate 4 can be pulled inward to improve the stability of the connection. At the same time, the top plate 5 can further compress the heat sink 9 to improve the stability of the heat sink 9 after it is connected to the frame 1, while avoiding wear on the heat sink 9. In order to avoid accidental opening of the sealing plate 4, when the pressing block 8 is fully attached to the top support plate 14, the spring 15 can insert the limiting block 16 into the positioning groove 17. Since the inner wall of the positioning groove 17 is inclined and the bottom end of the limiting block 16 is conical, the limiting block 16 will be pushed out of the positioning groove 17 when sufficient external force is applied, without affecting the normal disassembly of the heat sink 9.

[0021] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0022] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0023] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it.
