Description

Technical Field

[0001] The utility model relates to the field of auxiliary tools, and more specifically, to an auxiliary repair and replacement tool for a TV circuit board. Background Art

[0002] A TV circuit board is a device used to receive signals and control a TV. The patent publication number CN220528121U discloses a TV circuit board, which includes a TV mounting base. A circuit board with components is fixedly connected to the top of the TV mounting base. A plurality of heat dissipation holes are evenly drilled on the four sides of the components. A card slot is fixedly connected to the outside of the circuit board, and a hose is fixedly connected in the card slot and abuts against the circuit board. When the TV is watched for a long time, a large amount of heat will be generated by the internal chips and components. At this time, the heat dissipated by the components will be dissipated through the heat dissipation holes. At the same time, after the hose is placed in the card slot and aligned with the liquid injection port, its position is fixed by a slot cover, and then the hose is filled with a coolant through the liquid injection port and sealed with a sealing cover. At this time, the hose is attached to the circuit board, so that the coolant cools the whole circuit board, effectively achieving the effect of quickly cooling and dissipating heat of the circuit board.

[0003] In the existing technology, although the above circuit board can achieve a good heat dissipation effect and the hose can be quickly replaced, when the hose is damaged, the internal coolant will directly flow onto the circuit board, causing irreversible damage. In serious cases, when replacement is required, the staff also needs to clean the coolant at the installation position of the circuit board to prevent damage to the new circuit board. The coolant is generally composed of water, ethylene glycol and other additives, etc. Therefore, some special cleaning agents need to be mixed and then sucked out. Therefore, maintenance personnel need to carry a lot of tools, and the maintenance is relatively cumbersome, which increases the limitation of the circuit board during maintenance.

[0028] Embodiment 1:

[0029] Please refer to Figures 1-4 , a television circuit board auxiliary repair and replacement tool, including a television mounting base 1 and a U-shaped frame 5. The top surface of the television mounting base 1 is provided with a buckle 2 and a hose 3. A circuit board 4 is detachably installed at the top of the television mounting base 1 and located at the hose 3. The top end of the U-shaped frame 5 is fixedly installed with a grip rod 501. Spraying devices 6 are fixedly installed on both the left and right sides of the U-shaped frame 5. A pull plate 502 is slidably installed inside the top end of the U-shaped frame 5 and located at the bottom end of the grip rod 501. A right-angle plate 503 is fixedly installed at the bottom end of the pull plate 502. A clamping post 504 is fixedly installed inside the bottom end of the right-angle plate 503. An adsorption roller 506 is detachably installed on the surface of the clamping post 504. The spraying device 6 includes a pressing frame 601. Pressing rods 602 are fixedly installed at the bottom ends of both the left and right sides of the pressing frame 601. A second spring 603 is movably sleeved on the surface of the pressing rod 602. The bottom end of the second spring 603 is fixedly connected to a solvent box 604. The bottom end of the solvent box 604 is fixedly communicated with an arc-shaped tube 606. The bottom end of the arc-shaped tube 606 is fixedly communicated with a nozzle 607. The number of the right-angle plates 503 is two. A first spring 505 is fixedly connected to the inside of both the two right-angle plates 503. The adsorption roller 506 is rotatably installed on the surface of the clamping post 504. A feeding tube 605 is fixedly communicated with the outer wall of the solvent box 604, and its inner wall is fixedly connected to the outer wall surface of the U-shaped frame 5. The top end of the second spring 603 is fixedly connected to the bottom surface of both the left and right ends of the pressing frame 601. The bottom end of the pressing rod 602 is fixedly connected to a pressing plate 608. The side walls of the pressing plate 608 are all attached to the inner wall surface of the solvent box 604. A hard film is integrally formed at the port of the nozzle 607.

[0030] It should be noted that the TV mounting base 1, buckle 2, hose 3, and circuit board 4 in this utility model are all components with the same names in the comparative document, and their functions and corresponding connection methods are the same, so no further elaboration will be made. In addition, the sizes of the U-shaped frame 5 and the spraying device 6 are adapted to the size of the hose 3, which is a foreseeable means, so no further elaboration will be made either.

[0031] Specifically, the design of the hard film at the bottom of the nozzle 607 can prevent the anhydrous isopropyl alcohol solution in the solvent box 604 from falling when it is stationary, ensuring that the solvent will only be ejected when internal pressing pressure is applied. In addition, the curved surface design at the top of the pressing frame 601 can better adapt to the curvature of the thumb, improving the comfort of use. The spring 505 can ensure that the two right-angle plates 503 move the clamping post 504 inward statically to prevent the adsorption roller 506 from falling off, and it can also facilitate the simultaneous outward movement of the two clamping posts 504 to achieve the purpose of quickly replacing the adsorption roller 506, improving the practicality of itself.

[0032] The working principle of this utility model is as follows: Hold the grip 501, then use the thumb to press the pressing frame 601, driving the pressing rod 602 to press down on the pressing plate 608, spraying the internal anhydrous isopropyl alcohol into the placement position of the circuit board 4 on the top surface of the TV mounting base 1 through the arc tube 606 and the nozzle 607, and mixing it with the ethylene glycol solution remaining in the circuit board 4 by the hose 3. Then, move the grip 501 to drive the entire adsorption roller 506 to adsorb and clean the mixed solution. After the cleaning is completed, move the pull plate 502 backward to drive the right-angle plate 503 to move, so that the clamping post 504 disengages from the inside of the adsorption roller 506, and the adsorption roller 506 can be taken out from the inside of the U-shaped frame 5, and a new adsorption roller 506 can be replaced.

[0033] The above is only the preferred specific embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by this utility model, according to the technical solution of this utility model and its improved concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of this utility model.
