It is manufactured using electronic printing technology and designed through CAD software, and the production process involves complex chemical and mechanical processing techniques.

[0003] During the actual use of the PCB circuit board, due to the influence of the surrounding environment, corrosive liquid may drip onto the circuit board. At this time, if the corrosive liquid is not effectively removed, the circuit board will be corroded and damaged, which will in turn affect the normal operation of the circuit board. Therefore, a PCB circuit board with a function of adsorbing corrosive liquid is hereby proposed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a PCB circuit board with a function of adsorbing corrosive liquid, which solves the problem that in the prior art, due to the influence of the surrounding environment, corrosive liquid may drip onto the circuit board. At this time, if the corrosive liquid is not effectively removed, the circuit board will be corroded and damaged, which will in turn affect the normal operation of the circuit board.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Through grooves are opened on both sides of the outer frame. Structure grooves are opened on both sides of the outer wall on both sides of the outer frame. A plug rod is horizontally arranged in the inner cavity of the structure groove. Docking grooves are opened on both inner walls of the through groove. A cross bar is slidably connected in the inner cavity of the through groove. A sponge is fixedly connected to one side of the cross bar. Docking blocks adapted to the docking grooves are fixedly connected to both ends of the cross bar. A jack is opened on one side of the docking block. One end of the plug rod penetrates through the side wall of the adjacent structure groove and is inserted into the corresponding jack, and the other end of the plug rod penetrates through the side wall of the adjacent structure groove and extends to one side of the outer frame.

[0013] When in use, first, the sponge needs to be installed. The user simultaneously pulls apart two corresponding insertion rods, so that the insertion rods are separated from the inner cavities of the corresponding docking grooves. Then, the user inserts the docking blocks on both sides of the cross bar into the inner cavities of the adapted docking grooves respectively, so that the position of the cross bar in the inner cavity of the through groove is limited. The user releases the insertion rods, and the baffle transmits the acting force of the spring to the insertion rods, thereby driving the insertion rods into the inner cavities of the corresponding jacks, achieving the limiting effect on the docking blocks.

Through the setting of the structure groove, the occupation of the external space of the structure by its internal structure is reduced. Through the setting of the handle, the friction force for the user to pull the insertion rod is increased. Through the setting of the docking block and the docking groove, it is convenient for the user to install or replace the sponge. Through the setting of the through groove, an effective space is provided for the installation of the sponge. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0024] Refer to Figures 1-5, a PCB circuit board with a function of adsorbing corrosive liquid, including an outer frame 1. The bottom of the inner cavity of the outer frame 1 is provided with a circuit board body 2. Through grooves 13 are opened on both sides of the outer frame 1. Structure grooves 4 are opened on both sides of the outer walls on both sides of the outer frame 1. A plug rod 9 is horizontally arranged in the inner cavity of the structure groove 4. Docking grooves 8 are opened on both inner walls of the through groove 13. A cross bar 3 is slidably connected in the inner cavity of the through groove 13. A sponge 6 is fixedly connected to one side of the cross bar 3. Docking blocks 5 adapted to the docking grooves 8 are fixedly connected to both ends of the cross bar 3. A jack 7 is opened on one side of the docking block 5. One end of the plug rod 9 penetrates through the side wall of the adjacent structure groove 4 and is inserted into the corresponding jack 7. The other end of the plug rod 9 penetrates through the side wall of the adjacent structure groove 4 and extends to one side of the outer frame 1. Specifically, when in use, first, the sponge 6 needs to be installed. The user simultaneously pulls apart two corresponding plug rods 9, so that the plug rods 9 are disengaged from the inner cavities of the corresponding docking grooves 8. Then the user inserts the docking blocks 5 on both sides of the cross bar 3 into the inner cavities of the adapted docking grooves 8 respectively, so that the position of the cross bar 3 in the inner cavity of the through groove 13 is limited. The user releases the plug rods 9, and the force of the spring 10 is transmitted to the plug rods 9 through the retaining piece 11, thereby driving the plug rods 9 into the inner cavities of the corresponding jacks 7, achieving the limiting effect on the docking blocks 5. When the surface of the circuit board body 2 is contaminated with liquid, affected by gravity, the liquid will fall into the inner cavity of the outer frame 1, and the sponge 6 adsorbs the liquid, thus preventing the corrosion phenomenon caused by the liquid always adhering to the circuit board body 2. Through the structural design, the situation that the liquid on the surface of the circuit board body 2 cannot be effectively adsorbed is prevented, the protection effect on the circuit board body 2 is improved, the quality during the use of the circuit board body 2 is strengthened, and the potential safety hazards during use are reduced.

[0025] This solution has the following working process:

[0026] When in use, first, the sponge 6 needs to be installed. The user simultaneously pulls apart two corresponding plug rods 9, so that the plug rods 9 are disengaged from the inner cavities of the corresponding docking grooves 8. Then the user inserts the docking blocks 5 on both sides of the cross bar 3 into the inner cavities of the adapted docking grooves 8 respectively, so that the position of the cross bar 3 in the inner cavity of the through groove 13 is limited. The user releases the plug rods 9, and the force of the spring 10 is transmitted to the plug rods 9 through the retaining piece 11, thereby driving the plug rods 9 into the inner cavities of the corresponding jacks 7, achieving the limiting effect on the docking blocks 5. When the surface of the circuit board body 2 is contaminated with liquid, affected by gravity, the liquid will fall into the inner cavity of the outer frame 1, and the sponge 6 adsorbs the liquid, thus preventing the corrosion phenomenon caused by the liquid always adhering to the circuit board body 2.

[0027] According to the above working process, it can be known that:

[0028] Through structural design, the situation where the liquid on the surface of the circuit board body 2 cannot be effectively adsorbed is prevented, the protection effect on the circuit board body 2 is improved, the quality during the use of the circuit board body 2 is enhanced, and the potential safety hazards during use are reduced.

[0029] Further, a retaining piece 11 is sleeved on the outer ring of the insertion rod 9 and located inside the corresponding structural groove 4. One end of the retaining piece 11 abuts against the inner side wall of the adjacent structural groove 4. Specifically, through the setting of the retaining piece 11, the acting force of the spring 10 can be effectively transmitted to the corresponding insertion rod 9.

[0030] Further, a spring 10 is installed on the outer ring of the insertion rod 9. One end of the spring 10 is fixedly connected to one side of the adjacent retaining piece 11, and the other end of the spring 10 is fixedly connected to the inner side wall of the adjacent structural groove 4. Specifically, through the setting of the structural groove 4, the occupation of the external space of the structure by its internal structure is reduced.

[0031] Further, a handle 12 is fixedly connected to the end of the insertion rod 9 away from the retaining piece 11. Specifically, through the setting of the handle 12, the friction force for a person to pull the insertion rod 9 is increased.

[0032] Further, the outer ring of the cross bar 3 is adapted to the inner cavity of the corresponding through groove 13, and one side of the docking block 5 abuts against the inner side wall of the adjacent docking groove 8. Specifically, through the setting of the docking block 5 and the docking groove 8, it is convenient for a person to install or replace the sponge 6.

[0033] Further, the inner cavities of the two corresponding docking grooves 8 are both communicated with the inner cavity of the adjacent through groove 13. Specifically, through the setting of the through groove 13, an effective space is provided for the installation of the sponge 6.

[0034] In summary: When in use, first, the sponge 6 needs to be installed. The user simultaneously pulls two corresponding insertion rods 9 apart, so that the insertion rods 9 are disengaged from the inner cavities of the corresponding docking grooves 8. Then, the user inserts the docking blocks 5 on both sides of the cross bar 3 into the inner cavities of the adaptively matched docking grooves 8 respectively, thereby limiting the position of the cross bar 3 in the through groove 13. The user releases the insertion rods 9, and the force of the spring 10 is transmitted to the insertion rods 9 through the retaining pieces 11, thereby driving the insertion rods 9 to enter the inner cavities of the corresponding insertion holes 7, achieving the limiting effect on the docking blocks 5. When the surface of the circuit board body 2 is contaminated with liquid, affected by gravity, the liquid will fall into the inner cavity of the outer frame 1, and the sponge 6 adsorbs the liquid, thus preventing the corrosion phenomenon caused by the liquid always adhering to the circuit board body 2. Through the setting of the retaining pieces 11, the force of the spring 10 can be effectively transmitted to the corresponding insertion rods 9. Through the setting of the structural grooves 4, the occupation of the external space of this structure by its internal structure is reduced. Through the setting of the handle 12, the friction force for the user to pull the insertion rods 9 is increased. Through the setting of the docking blocks 5 and the docking grooves 8, it is convenient for the user to install or replace the sponge 6. Through the setting of the through groove 13, an effective space is provided for the installation of the sponge 6. Through the structural design, the situation where the liquid on the surface of the circuit board body 2 cannot be effectively adsorbed is prevented, the protection effect on the circuit board body 2 is improved, the quality during the use of the circuit board body 2 is enhanced, and the potential safety hazards during use are reduced.
