DETAILED DESCRIPTION

[0015] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific purposes.

[0016] like Figure 1-2A portable injection gun for plugging agent shown in the figure comprises two front and rear handles 1 and a solvent cartridge 2 placed horizontally above the handle 1, a piston 3 that slides back and forth is installed in the solvent cartridge 2, a magnetic coupling piece that slides back and forth is sleeved on the outside of the solvent cartridge 2, a neodymium magnet block that cooperates with the magnetic coupling piece is embedded in the piston 3, a driving piece that drives the magnetic coupling piece to slide back and forth outside the solvent cartridge 2 is arranged below the solvent cartridge 2, and the magnetic coupling piece drives the piston 3 to move in the solvent cartridge 2 through magnetic coupling during the back and forth sliding process to inject the plugging agent;

[0017] On the basis of the above, the plugging agent is placed inside the solvent cylinder 2 when in use, and the driving part drives the magnetic coupling part to slide back and forth along the direction of the solvent cylinder 2. The magnetic coupling part is coupled with the neodymium magnet block in the piston 3 to drive the piston 3 to move in the solvent cylinder 2, and push the plugging agent stored in the solvent cylinder 2 to the outside.

[0018] The driving member includes an equipment platform 4 located below the rear end of the solvent cylinder 2 and a screw 5 placed horizontally below the solvent cylinder 2. A bent and extended connecting rod 6 is fixedly installed at the rear end of the solvent cylinder 2. The bottom end of the connecting rod 6 is fixed to the surface of the top end of the equipment platform 4. The top end of the handle 1 located at the rear side is fixedly installed at the bottom of the equipment platform 4.

[0019] The rear end of the solvent cylinder 2 is fixed to the equipment platform 4 through the connecting rod 6, and the equipment platform 4 is fixed to the top of the handle 1 at the rear side, so as to support and fix the rear end of the solvent cylinder 2.

[0020] A funnel-shaped injection end 7 is provided at the front end of the solvent cylinder 2, an input tube 8 connected to the inside of the solvent cylinder 2 is installed on the top of the injection end 7, and a detachable sealing plug 16 is installed in the input tube 8. When the sealing plug 16 extends into the inner cavity of the input tube 8 and seals the input tube 8, the bottom end of the sealing plug 16 is flush with the inner wall of the injection end 7;

[0021] Furthermore, a connected extrusion tube 17 is installed at the front end of the injection end 7. When the piston 3 moves, the plugging agent is pushed from the injection end 7 to the extrusion tube 17 and extruded from the end of the extrusion tube 17. After the plugging agent is injected, the plugging agent can be re-added to the solvent cylinder 2 through the input tube 8 for next use. After the plugging agent is replenished, the input tube 8 is sealed with a sealing plug 16.

[0022] Among them, the end of the piston 3 is consistent with the inside of the injection end 7, so that the remaining plugging agent in the injection end 7 can be completely squeezed out during the plugging agent extrusion to avoid residue, and the bottom end of the sealing plug 16 is flush with the inner wall of the injection end 7, so that when the piston 3 is in contact with the inner wall of the injection end 7, there will be no conflict between the bottom end of the sealing plug 16.

[0023] A downwardly extending input tube 9 is fixed at the bottom of the injection end 7, a positioning block 10 is installed at the bottom of the input tube 9, the positioning block 10 is fixed to the top of the handle 1 located at the front side, a bearing 11 is fixedly installed on the outer wall of the positioning block 10, and the front end of the screw 5 is inserted into the inside of the bearing 11.

[0024] The front end of the solvent cartridge 2 is installed and fixed on the top of the handle 1 located at the front side through the input tube 9. When in use, the two handles 1 at the front and rear sides are held to lift the entire injection device to inject the plugging agent.

[0025] A driving motor 12 is installed on the equipment platform 4 , the output shaft end of the driving motor 12 is fixedly connected to the rear end of the screw 5 , and a screw tube 13 sliding along the screw 5 is sleeved on the outside of the screw 5 .

[0026] Furthermore, the screw 5 is fixed at the bottom of the solvent cylinder 2 by the bearing 11 at the front side and the output shaft of the driving motor 12 at the rear side, connected between the two, and the driving motor 12 drives the screw 5 to rotate in the bearing 11.

[0027] The magnetic coupling member includes a neodymium magnetic ring 14 sleeved on the outer wall of the solvent cylinder 2, the neodymium magnetic ring 14 is attracted to the neodymium magnetic block embedded in the piston 3, a circle of connecting ring 15 is wrapped around the outside of the neodymium magnetic ring 14, and the spiral tube 13 is fixedly connected to the connecting ring 15.

[0028] On the basis of the above, the screw 5 is fixed between the bearing 11 of the positioning block 10 and the output shaft of the driving motor 12. The top of the positioning block 10 is fixedly connected to the injection end 7 at the front end of the solvent barrel 2 through the input pipe 9. The equipment table 4 is fixedly connected to the rear end of the solvent barrel 2 through the connecting rod 6 to support the solvent barrel 2. The spiral tube 13 sleeved on the outside of the screw 5 is fixed to the connecting ring 15 on the outside of the solvent barrel 2. When the screw 5 rotates, it will drive the spiral tube 13 to move along the extension direction of the screw 5, and then drive the connecting ring 15 and the neodymium magnetic ring 14 to move outside the solvent barrel 2. The neodymium magnetic ring 14 and the neodymium magnetic block embedded in the piston 3 are adsorbed. During the movement of the neodymium magnetic ring 14, the piston 3 is driven to move inside the solvent barrel 2, and the plugging agent is squeezed out from the injection end 7 at the front end of the solvent barrel 2 to the outside.

[0029] Furthermore, by utilizing the adsorption effect between the neodymium magnetic ring 14 and the neodymium magnetic block in the piston 3, the movement of the piston 3 in the solvent cylinder 2 is realized, thereby ensuring the integrity of the solvent cylinder 2. There is no need to drill holes to install other connecting components on the piston, thereby reducing the possibility of leakage and other failures.

[0030] Furthermore, a control button 18 is installed on the handle 1 at the rear side, and a power cord 19 is connected to the equipment table 4. The power cord 19 is used to supply power to the drive motor 12, and the control button 18 is used to control the drive motor 12.

[0031] Furthermore, the driving motor 12 is a servo motor, which can accurately control the number of revolutions. By controlling the number of revolutions, the distance that the spiral tube 13 moves outside the screw 5 is controlled, and then the moving distance of the piston 3 is controlled, and the extrusion amount of the plugging agent is controlled.
