[0028] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0029] like Figure 1 and Figure 2 As shown, a heat sink 10 includes a body 110 and at least two locking members 200. A protruding block 120 is provided on one side surface of the body 110, and a plurality of heat dissipation teeth 130 are provided on the other side surface of the body 110. The locking members 200 are arranged on the body 110 at intervals. The locking members 200 include a locking screw 210 and an elastic member 220. A locking hole is provided on the body 110. The locking screw 210 is passed through the locking hole from a side of the body 110 close to the heat dissipation teeth 130 so that one end of the locking screw 210 is engaged with the body 110. The elastic member 220 is sleeved on the locking screw 210 so that the elastic member 220 is respectively in contact with the locking screw 210 and the body 110. An inner screw hole 211 is provided on one end of the locking screw 210 close to the protruding block 120.

[0030] It should be noted that each locking member 200 is pre-installed on the body 110 to form an integral structure. Specifically, a locking hole is defined in the body 110. After the locking screw 210 passes through the body 110 from the side of the body 110 near the heat dissipation teeth 130, the end of the locking screw 210 that passes through the body 110 engages with the body 110. This allows the body 110 to slide relative to the body 110 to approach the protruding block 120 but prevents it from being withdrawn from the body 110. Furthermore, an elastic member 220 is fitted over the locking screw 210 and abuts against both the body 110 and the locking screw 210, respectively. For example, the elastic member 220 is a coil spring. As a result, the elastic thrust of the elastic member 220 tends to disengage the locking screw 210 from the body 110. However, due to the engagement between the locking screw 210 and the body 110, the locking screw 210 forms a stable integral structure with the body 110 under the action of the elastic member 220. In this way, when installing the radiator 10, there is no need to use additional independent screws. Since the locking screw 210 is pre-installed on the main body 110, you only need to press and rotate the locking screw 210 to tighten the locking screw 210 to the specified position through the inner screw hole 211, so that the main body 110 can be installed and fixed quickly and reliably, thereby effectively improving the installation safety.

[0031] like Figure 2 As shown, in one embodiment, one end of the locking screw 210 close to the inner screw hole 211 is trumpet-shaped.

[0032] Thus, the diameter of the end of the locking screw 210 close to the inner screw hole 211 is larger than the diameter of the rest of the locking screw 210 , so that the locking screw 210 is clamped in the locking hole and will not retreat from the locking hole.

[0033] In one embodiment, two locking members 200 are provided, and the two locking members 200 are respectively located on two opposite sides of the body 110. In this way, the body 110 can be reliably installed and used through the two locking members 200.

[0034] like Figure 1 As shown, in one embodiment, the heat dissipation teeth 130 are equidistantly distributed. Thus, when the heat sink 10 is mounted on a chip or other location, the bumps 120 abut against the chip or other heat generating components, and the heat is dissipated through the heat dissipation teeth 130 .

[0035] In one embodiment, the elastic member 220 is a spring, so that the locking screw 210 and the body 110 are stably engaged with each other under the elastic thrust of the spring.

[0036] like Figure 3 and Figure 4As shown, a riveting device 1 is used to assemble any of the above-mentioned heat sinks 10, which includes a base 1000, a loading base 2000, a punching drive 3000, a punching block 4000, a pre-pressing drive 5000, a pre-pressing head 6000 and at least two punching rods 7000, the loading base 2000 is arranged on the base 1000, the loading base 2000 is provided with a loading groove 2100 for accommodating the heat sink 10, the punching drive 3000 is arranged on the base 1000, and the punching block 4000 is arranged on the punching drive 3000. On the output shaft of the pre-pressing drive 5000, the stamping drive 3000 is used to drive the stamping block 4000 to perform lifting movements, the pre-pressing drive 5000 is adjacent to the loading seat 2000 and is arranged on the machine base 1000, the pre-pressing head 6000 is arranged on the output shaft of the pre-pressing drive 5000, and each stamping rod 7000 is slidably arranged on the output shaft of the pre-pressing drive 5000, and the pre-pressing drive 5000 is used to drive the pre-pressing head 6000 to press the radiator 10 so that each stamping rod 7000 respectively abuts against one end of each locking screw 210 close to the inner screw hole 211.

[0037] It should be noted that the loading seat 2000 is installed on the machine base 1000, the stamping drive 3000 is installed on the machine base 1000, the stamping block 4000 is installed on the output shaft of the stamping drive 3000, and the stamping block 4000 is located above the loading seat 2000. In this way, the stamping block 4000 is driven by the stamping drive 3000 to perform lifting movements, the pre-stressing drive 5000 is installed on the machine base 1000, and the pre-stressing drive 5000 is arranged adjacent to the loading seat 2000. A loading trough 2100 is provided in the loading base 2000, and the pre-pressing head 6000 is installed on the output shaft of the pre-pressing driving component 5000, so that the pre-pressing head 6000 is driven by the pre-pressing driving component 5000 to approach or move away from the loading trough 2100. When it approaches the loading trough 2100, it can press the radiator 10 located in the loading trough 2100. Furthermore, two punching rods 7000 are slidably installed on the output shaft of the pre-pressing driving component 5000, and the punching rods 7000 can slide freely relative to the output shaft of the pre-pressing driving component 5000. In this way, when the pre-pressing driving component 5000 drives the pre-pressing head 6000 to press the radiator 10, the punching rod 7000 will be aligned and abut against the end of the locking screw 210 close to the inner screw hole 211 under the action of its own gravity. In this way, the punching drive 3000 drives the punching block 4000 to descend, causing the punching block 4000 to impact the two punching rods 7000. The punching rods 7000 will punch and deform the end of the locking screw 210 close to the inner screw hole 211 into a trumpet-shaped structure. In one embodiment, the punching drive 3000 is a cylinder, and the pre-stressing drive 5000 is a toggle clamp. In this way, the locking screw 210 can be stably assembled with the body 110. By abutting the punching rod 7000 against the locking screw 210 in advance, the punching accuracy is ensured, and the deformation of the locking screw 210 due to the offset of the punching rod 7000 during the punching process can be avoided, effectively improving the assembly accuracy and efficiency.

[0038] like Figure 4 As shown, in one embodiment, at least two limiting slots 2200 are further defined on the loading base 2000 , so that each locking screw 210 is respectively accommodated in each limiting slot 2200 .

[0039] It should be noted that the locking screw 210 needs to be installed on the main body 110 together with the elastic part 220. In order to facilitate the correct placement of the elastic part 220 and the locking screw 210 relative to the main body 110, when the loading trough 2100 is used to accommodate the main body 110, the locking screw 210 and the elastic part 220 are accommodated by the limiting groove 2200.

[0040] like Figure 3 As shown, in one embodiment, the riveting device 1 further includes a guide block 8000 , which is disposed on the output shaft of the pre-pressing driver 5000 , and each punching rod 7000 is passed through the guide block 8000 .

[0041] For example, the pre-pressing head 6000 can be sequentially passed through the output shaft of the pre-pressing driver 5000 and the guide block 8000, and then nuts are used to tighten and secure the pre-pressing head 6000 from both ends, so that the guide block 8000 and the pre-pressing head 6000 are locked and secured to the output shaft of the pre-pressing driver 5000. Then, a through hole is formed in the guide block 8000, and the punching rod 7000 is passed through the through hole, so that the punching rod 7000 can slide relative to the guide block 8000.

[0042] like Figure 3 and Figure 5 As shown, in one embodiment, the riveting device 1 further includes at least two pre-pressing members 9000 , each pre-pressing member 9000 is disposed on the guide block 8000 at intervals, and each pre-pressing member 9000 is connected to each punching rod 7000 .

[0043] It should be noted that the pre-stressing drive 5000 is used to drive the guide block 8000 towards or away from the loading trough 2100, and the punching rod 7000 can slide relative to the guide block 8000. In order to prevent the punching rod 7000 from falling off the guide block 8000 during this process, and at the same time to ensure that when the pre-stressing head 6000 presses the radiator 10, each punching rod 7000 can stably and accurately abut against the locking screw 210, a pre-stressing part 9000 is provided to pre-stress the punching rod 7000.

[0044] like Figure 5 As shown, in one embodiment, the pre-stressing member 9000 includes a stopper 9100, a collar 9200 and a pre-stressing spring 9300, the collar 9200 is adjustably mounted on the punching rod 7000, the stopper 9100 is arranged on the guide block 8000, the pre-stressing spring 9300 is mounted on the punching rod 7000, and the pre-stressing spring 9300 is respectively in contact with the guide block 8000 and the collar 9200.

[0045] It should be noted that the stopper 9100 is fixed to the guide block 8000 by screws, the punching rod 7000 passes through the guide block 8000 and the stopper 9100 in sequence, and the collar 9200 is sleeved on the punching rod 7000, and the position of the collar 9200 relative to the punching rod 7000 is adjustable. The preload spring 9300 is sleeved on the punching rod 7000, and the preload spring 9300 abuts the punching rod 7000 and the collar 9200 respectively. In this way, under the push of the preload spring 9300, the punching rod 7000 has a tendency to pass through the stopper 9100, but because the stopper 9100 is stuck to the collar 9200, the punching rod 7000 will not fall out of the stopper 9100. As a result, when the preload driver 5000 drives the preload head 6000 to press the heat sink 10, the punching rods 7000 abut against the end of the locking screw 210 near the inner threaded hole 211, compressing the preload spring 9300. The punching driver 3000 then drives the punching block 4000 downward to press each punching rod 7000, forming a trumpet-shaped structure on the end of the locking screw 210 near the inner threaded hole 211.

[0046] like Figure 5 As shown, in one embodiment, a frustum 7100 is provided at the end of the punching rod 7000 . Thus, the frustum 7100 can be used to form a horn structure on one end of the locking screw 210 close to the inner screw hole 211 .

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in the present invention can be understood to include but not be limited to locking and fixing with screws / screws and welding. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
