[0018] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Example like Figure 1 , Figure 2 , Figure 5 , Figure 6 and Fig. 9 As shown, a heat dissipation fixing bracket for electronic products comprises a base 1, a lifting unit 2 is provided on the base 1, a clamping unit 4 for clamping the electronic product is provided on the lifting unit 2, the clamping unit 4 comprises a clamping column 45, a suction unit 7 for increasing the clamping stability is provided at the head of the clamping column 45, a separation unit 8 is provided in the suction unit 7, and a stabilizing unit 5 for fixing the height of the lifting unit 2 is provided below the lifting unit 2; The clamping unit 4 further comprises a pair of bases 41, the bases 41 are fixedly connected to the upper end surface of the lifting unit 2, a hydraulic chamber 43 is provided in the base 41, an external hydraulic pipe 42 is fixedly connected to one side of the base 41, the external hydraulic pipe 42 is communicated with the hydraulic chamber 43, a slide groove 44 is provided on one side of the hydraulic chamber 43, the slide groove 44 is provided in the base 41, a clamping column 45 is slidably connected in the slide groove 44, a sealing ring 46 is provided at one end of the clamping column 45 close to the external hydraulic pipe 42, the sealing ring 46 and the slide groove 44 are slidably fitted, a support spring 47 is nested on the clamping column 45, and an end of the support spring 47 away from the hydraulic chamber 43 is fixedly connected to the inner wall of the slide groove 44; The adsorption unit 7 comprises a groove 72, and the groove 72 is arranged at the end of the clamping column 45 away from the hydraulic chamber 43, and a ball 73 is rotatably clamped in the groove 72, and a suction cup 71 is fixedly connected to the ball 73; One end of the clamping column 45 away from the hydraulic chamber 43 is designed to be circular so that the suction cup 71 can rotate at a larger angle.

[0020] In the embodiment, the electronic product to be clamped is placed on the lifting plate 21, or the electronic product is held so that the electronic product is located between the two bases 41. The hydraulic pump is then started externally, and the hydraulic pump transports the hydraulic oil to the hydraulic chamber 43 in the base 41 through the external hydraulic pipe 42. When the hydraulic chamber 43 is filled with hydraulic oil, the hydraulic oil begins to push the clamping column 45 to slide in the slide groove 44 close to the electronic product. The sealing ring 46 prevents leakage of hydraulic oil. At the same time, the support spring 47 is compressed. When the clamping column 45 slides, it drives the suction cup 71 to contact the outer shell of the electronic product, thereby fixing the electronic product.

[0021] It should be noted that the ball 73 drives the suction cup 71 to be movably connected in the groove 72 at the end of the clamping column 45. The suction cup 71 can rotate freely so as to better fit the housing of different electronic products and achieve a better fixing effect. At the same time, the circular design at the end of the clamping column 45 can make the suction cup 71 have a wider rotation range and is suitable for a variety of tilted housings.

[0022] It should also be noted that there are multiple groups of clamping posts 45, and the clamping posts 45 in contact with the electronic product housing will have a clamping force on the electronic product housing, and can clamp electronic products of various specifications.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a rotation damper 23 is fixedly connected to the base 1, and a plurality of connecting plates 22 are connected in series through the rotation damper 23. A lifting plate 21 is fixedly connected to the top rotation damper 23, and a notch is provided on the lifting plate 21, in which a cooling fan 3 for heat dissipation is provided.

[0024] In the embodiment, before fixing the electronic product, the user can manually pull the lifting plate 21 upward or press it downward, and adjust the height of the lifting plate 21 through the cooperation of the connecting plate 22 and the rotation damper 23. At the same time, after the heat dissipation fan 3 is turned on, the electronic product can be cooled. When repairing the electronic product, welding and other operations are involved, which will generate heat and welding smoke. After the heat dissipation fan 3 is started, the heat and welding smoke can be attracted downward to facilitate the maintenance work.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the stabilizing unit 5 includes a sliding bar 52, which is fixedly connected to the bottom end of the lifting plate 21. An opening 54 is provided on the base 1. The lower end of the sliding bar 52 passes through the opening 54 and extends to the bottom of the base 1. A water bag 53 is provided on the inner wall of the opening 54. The water bag 53 is connected to the hydraulic chamber 43 through the hydraulic pipe 55. A winding box 56 is fixedly connected to the side wall of the sliding bar 52. The winding box 56 winds up and tightens the hydraulic pipe 55. A tooth pattern 51 is provided on a surface of the sliding bar 52 that is close to the water bag 53 , and the tooth pattern 51 is used to increase the friction between the sliding bar 52 and the water bag 53 .

[0026] In the embodiment, when the hydraulic chamber 43 is filled with hydraulic oil, the hydraulic oil will enter the water bag 53 through the hydraulic pipe 55. After the water bag 53 expands, it will contact the tooth pattern 51 on the sliding bar 52. At this time, the position of the sliding bar 52 is fixed, so that the height of the lifting plate 21 and the fixed electronic product is fixed. When the user is repairing the electronic product, there will be pressing pressure on the electronic product, causing the lifting plate 21 and the electronic product to move down. The above process fixes the height of the lifting plate 21, which is convenient for the user to repair the electronic product.

[0027] like Figure 1 , Fig. 9 and Fig.10 As shown, the separation unit 8 includes an abutment tube 81, which is slidably connected to the center of the suction cup 71, and a first slideway 82 is provided at one end of the ball bearing 73 close to the suction cup 71, and one end of the abutment tube 81 extends into the first slideway 82, a first sealing ring 85 is fixedly connected in the first slideway 82, and a second sealing ring 86 is fixedly connected to one end of the abutment tube 81 away from the suction cup 71; A circular cavity 83 is provided in the ball bearing 73, the first slideway 82 is communicated with the circular cavity 83, an exhaust hole 84 is provided on the ball bearing 73, the exhaust hole 84 is communicated with the circular cavity 83, a second slideway 87 is provided on one side of the first slideway 82, the second slideway 87 is provided in the ball bearing 73, the second slideway 87 is communicated with the circular cavity 83, one end of the second slideway 87 close to the abutting tube 81 is slidably connected with a sliding plate 88, one end of the sliding plate 88 away from the abutting tube 81 is fixedly connected with a return spring 89, and the other end of the return spring 89 is fixedly connected to the bottom of the second slideway 87.

[0028] In the embodiment, during the contact between the suction cup 71 and the housing of the electronic product, the abutment tube 81 will contact the housing of the electronic product, and then the abutment tube 81 will slide from the first slide 82 to the second slide 87, and then the end of the abutment tube 81 will push the sliding plate 88 (the sliding plate 88 and the second slide 87 are slidingly and sealingly connected) to slide in the second slide 87 and compress the reset spring 89, at this time, the second sealing ring 86 at the end of the abutment tube 81 is slidingly and sealingly connected to the second slide 87, and the first sealing ring 85 seals the gap between the abutment tube 81 and the first slide 82, at this time, a seal is formed between the suction cup 71, the first slide 82, the abutment tube 81, the second slide 87 and the sliding plate 88, so that the suction cup 71 has suction.

[0029] It should be noted that when the conventional suction cup 71 is pulled away from the electronic product housing, the suction cup 71 will first be deformed, and the inside of the suction cup 71 is still in a negative pressure state. When the suction cup 71 is pulled away from the electronic product housing by continued force, the suction cup 71 and the electronic product housing are separated. However, increasing the force to stretch the suction cup 71 will accelerate the aging of the suction cup 71 and damage the electronic product. When the suction cup 71 is pulled away from the electronic product housing, the suction cup 71 will first be deformed, and the inside of the suction cup 71 is in a negative pressure state. However, at this time, the end of the abutting tube 81 close to the electronic product housing is no longer subjected to the pressure of the electronic product housing. The restoring spring 89 extends to drive the sliding plate 88 and the abutting tube 81 to slide toward the suction cup 71. In this process, the end of the abutting tube 81 close to the sliding plate 88 will pass through the circular cavity 83. At this time, the circular cavity 83, the exhaust hole 84, the abutting tube 81 and the suction cup 71 form a passage. The negative pressure in the suction cup 71 disappears instantly, and the suction cup 71 is more easily separated from the electronic product housing, thereby increasing the service life of the suction cup 71.

[0030] The workflow is as follows: First, the user can manually pull the lifting plate 21 upward or press it downward, and adjust the height of the lifting plate 21 through the cooperation of the connecting plate 22 and the rotary damper 23. Then, place the electronic product between the two bases 41, and the hydraulic pump will transport the hydraulic oil to the hydraulic chamber 43 in the base 41 through the external hydraulic pipe 42. When the hydraulic chamber 43 is filled with hydraulic oil, the hydraulic oil begins to push the clamping column 45 to slide in the slide groove 44 and approach the electronic product. When sliding, the clamping column 45 will drive the suction cup 71 to contact the outer shell of the electronic product. During the contact between the suction cup 71 and the outer shell of the electronic product, the abutment tube 81 will contact the outer shell of the electronic product, and then the abutment tube 81 will slide from the first slide 82 to the second slide 87. The end of the rear abutment tube 81 will push the sliding plate 88 (the sliding plate 88 and the second slideway 87 are slidably sealed and connected) to slide in the second slideway 87 and compress the reset spring 89. At this time, the second sealing ring 86 at the end of the abutment tube 81 is slidably sealed and connected with the second slideway 87, and the first sealing ring 85 seals the gap between the abutment tube 81 and the first slideway 82. At this time, a seal is formed between the suction cup 71, the first slideway 82, the abutment tube 81, the second slideway 87 and the sliding plate 88, so that the suction cup 71 has suction force, thereby achieving the fixation of the electronic product. In this process, the hydraulic oil will enter the water bag 53 through the hydraulic pipe 55. After the water bag 53 expands, it contacts the tooth pattern 51 on the sliding bar 52, so that the height of the lifting plate 21 and the fixed electronic product is fixed. Before repairing the electronic product, turn on the heat dissipation fan 3 to dissipate the heat of the electronic product. When repairing the electronic product, welding and other operations will be involved, which will generate heat and welding smoke. After the heat dissipation fan 3 is started, the heat and welding smoke can be attracted downward, which is convenient for the maintenance work. After the maintenance is completed, when the suction cup 71 is pulled away from the electronic product housing, the suction cup 71 is deformed first, and at the same time, the inside of the suction cup 71 is in a negative pressure state. However, at this time, the end of the abutment tube 81 close to the electronic product housing is no longer subjected to the pressure of the electronic product housing, and the return spring 89 extends to drive the sliding plate 88 and the abutment tube 81 to slide toward the suction cup 71. During this process, the end of the abutment tube 81 close to the sliding plate 88 will pass through the circular cavity 83. At this time, the circular cavity 83, the exhaust hole 84, the abutment tube 81 and the suction cup 71 form a passage, and the negative pressure in the suction cup 71 disappears instantly, making it easier for the suction cup 71 to be separated from the electronic product housing, thereby increasing the service life of the suction cup 71.
