[0022] The utility model is described in further detail below:

[0023] like Figures 1 to 5 As shown, the utility model provides a radiator fastening device, including a PCB board 1, a radiator body 2 and a heating element 3, the heating element 3 is fixedly installed on the top of the PCB board 1, the radiator body 2 is arranged above the heating element 3, grooves 21 are opened on the left and right sides of the top of the radiator body 2, and a fastening component 4 is movably installed inside the groove 21; the fastening component 4 includes a connecting frame 41 that is movably clamped to the inner side of the groove 21, the bottom of the connecting frame 41 is fixedly connected to a limiting plate 42, a threaded rod 43 is rotatably installed inside the connecting frame 41, the top of the threaded rod 43 is fixedly connected to a handwheel 44 located outside the connecting frame 41, the outer thread of the threaded rod 43 is threadedly connected to a sliding rod 45 located in the connecting frame 41, the bottom inside the sliding rod 45 is fixedly installed with an anti-slip pad 46, the sliding rod 45 is movably clamped to the bottom of the PCB board 1, and the upper inside the inner side of the connecting frame 41 is fixedly connected to a mounting component 49.

[0024] By rotating the hand wheel 44, the threaded rod 43 located in the connecting frame 41 is driven to rotate, and the rotation of the threaded rod 43 drives the sliding rod 45 to slide upward along the connecting frame 41, so that the sliding rod 45 is retracted into the connecting frame 41. As the connecting frame 41 moves upward, the anti-slip pad 46 at the bottom is stuck on the bottom side of the PCB board 1, thereby locking and fixing the PCB board 1 and the radiator body 2. The overall structure is simple, easy to operate, and more convenient to use.

[0025] like Figure 4As shown, the mounting assembly 49 includes a shell 491, a mounting groove 492 is provided inside the shell 491, and sliding blocks 493 are movably connected to the front and rear sides of the mounting groove 492. The outer side of the sliding block 493 is fixedly connected to a fixed column 494 that penetrates the shell 491. A slot 495 is provided on the inner side of the sliding block 493, and a spring piece 496 is movably connected to the inside of the slot 495.

[0026] By pressing the sliding blocks 493 on the front and rear sides inward to squeeze the spring pieces 496 inside, the sliding blocks 493 drive the fixing column 494 to move inward along the installation groove 492. By clamping the outer shell 491 in the groove 21 and releasing the sliding block 493, the elastic force of the spring piece 496 pushes the fixing column 494 into the fixing hole 22 for fixation, thereby facilitating the fixing and disassembly of the installation component 49 in the groove 21 and facilitating installation.

[0027] like Figure 3 As shown, a through opening 47 is formed on the inner side of the connecting frame 41 , and a limiting block 48 located in the through opening 47 is fixedly connected to the outer side of the sliding rod 45 .

[0028] When the slide rod 45 slides along the connection frame 41 , the limit block 48 slides along the through opening 47 , thereby limiting the travel of the slide rod 45 and preventing the slide rod 45 from falling out of the bottom of the connection frame 41 .

[0029] like Figure 3 As shown, the lengths of the connecting frame 41 and the sliding rod 45 are equal.

[0030] Since the length of the connecting frame 41 is equal to that of the sliding rod 45 , the sliding rod 45 can be telescopically adjusted within the connecting frame 41 , thereby improving its application range.

[0031] like Figure 3 As shown, the slide bar 45 and the anti-slip pad 46 are both arranged in an “L” shape, and the anti-slip pad 46 is bonded to the inner side of the slide bar 45 .

[0032] The sliding rod 45 arranged in an "L" shape can be clamped on the bottom side of the PCB board 1 for locking and fixing, and the anti-skid pad 46 is made of rubber with anti-skid and wear-resistant properties to improve the stability effect.

[0033] like Figure 4 As shown, the mounting groove 492 is set with an open top, and the top of the sliding block 493 is located outside the mounting groove 492.

[0034] The installation slot 492 is provided with a top opening, and the pressing operation is facilitated by the portion of the sliding block 493 located outside the installation slot 492 .

[0035] like Figure 2 and Figure 4As shown, a fixing hole 22 corresponding to the fixing column 494 is opened inside the groove 21 , and the fixing column 494 is movably engaged in the fixing hole 22 .

[0036] Through the setting of the fixing hole 22 , the fixing column 494 is snapped into the fixing hole 22 to fix and limit the installation component 49 .

[0037] like Figure 4 As shown, the spring piece 496 is arranged in a "V" shape.

[0038] The metal material of the "V" shape of the spring piece 496 has high elasticity, which ensures its support strength for the sliding block 493 and its own service life.

[0039] The working principle of the radiator fastening device will be described in detail below.

[0040] like Figures 1 to 5 As shown, by pressing the sliding blocks 493 on the front and rear sides inward to squeeze the spring pieces 496 inside thereof, the sliding blocks 493 drive the fixing posts 494 to move inward along the mounting grooves 492, and by clamping the housing 491 in the groove 21, releasing the sliding blocks 493, the elastic force of the spring pieces 496 pushes the fixing posts 494 into the fixing holes 22 for fixing, and by setting the radiator body 2 above the heating element 3, by folding the connecting frame 41 inward along the groove 21, the anti-slip pad 46 on the lower inner side of the slide rod 45 is pressed against the anti-slip pad 46 on the lower inner side of the slide rod 45. Located below the PCB board 1, the hand wheel 44 is then rotated to drive the threaded rod 43 located in the connecting frame 41 to rotate. The rotation of the threaded rod 43 drives the sliding rod 45 to slide upward along the connecting frame 41, so that the sliding rod 45 is retracted into the connecting frame 41. As the connecting frame 41 moves upward, the anti-slip pad 46 at the bottom is stuck on the bottom side of the PCB board 1. The self-locking property of the threaded rod 43 fastens the sliding rod 45 to the bottom of the PCB board 1, thereby fastening the radiator body 2 and the PCB board 1 to each other.

[0041] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
