[0024] Example:

[0025] Reference Figure 1-Figure 5The reciprocating cleaning structure of the gun barrel includes a fixed frame 1, and a clamp for fixing to the gun barrel is fixedly arranged at the other end of the fixed frame 1. The clamp is suitable for the situation where the straightness of the driving rod 3 is good, that is, the bending is not obvious. When the driving rod 3 has obvious bending, a ball head seat can be fixed at the bottom of the fixed frame 1, and a sphere is arranged in the ball head seat. The connecting shaft is fixedly connected to the sphere, and then the end of the connecting shaft away from the sphere is fixed to the other frame. At this time, the ball head seat can adapt to the bending of the driving rod 3 and improve the use effect. It also includes: a brush head 2 for cleaning the gun barrel, a drive rod 3 is removably provided at one end of the brush head 2; at least one group of drive shafts 4, rotatably provided on the fixed frame 1. Here, we preferably provide two groups of drive shafts 4. For the convenience of description, the other group of drive shafts 4 is called support shafts. A motor is fixedly provided on the outer wall of the fixed frame 1, one end of the drive shaft 4 is fixedly connected to the output end of the motor, and a first synchronous pulley 402 is fixedly provided on the drive shaft 4, and a second synchronous pulley is fixedly provided on the support shaft. The first synchronous pulley 402 and the second synchronous pulley are driven by a synchronous belt, which can improve the driving effect of the drive rod 3, thereby realizing that the drive rod 3 carries the brush head 2 to slide back and forth in the gun barrel for cleaning. During the sliding process of the brush head 2, cleaning water can be introduced into the gun barrel through a water pipe. The cleaning effect can be improved by using agents or water. A lower pressing wheel 401 is fixedly provided at one end of the driving shaft 4 extending into the fixed frame 1, and a lower pressing wheel 401 is also fixedly provided on the supporting shaft. An upper pressing wheel 501 matching the lower pressing wheel 401 is provided for lifting in the fixed frame 1. That is to say, two groups of upper pressing wheels 501 are also provided, which correspond to the lower pressing wheels 401 on the driving shaft 4 and the supporting shaft respectively, and the driving rod 3 is slidably provided between the lower pressing wheel 401 and the upper pressing wheel 501. When the motor drives the driving shaft 4 to rotate, the lower pressing wheel 401 can be driven to rotate. With the cooperation of the upper pressing wheel 501, the driving rod 3 and the brush head 2 can be driven to slide back and forth in the barrel for cleaning. The structure is simple, the volume and weight are light, it is convenient to carry, and can meet the requirements of use.

[0026] During use, the lower pressing wheel 401 and the upper pressing wheel 501 are rotated in the fixed frame 1. Driven by the motor, the driving rod 3 and the brush head 2 can slide back and forth in the barrel for cleaning. The brush head 2 is detachably connected to the driving rod 3, and the length of the driving rod 3 can be assembled and disassembled through the threaded barrel 302. It has a simple structure, is easy to assemble and disassemble, is easy to carry, and improves the user experience.

[0027] Reference Figure 1 、 Figure 2 and Figure 4A guide sleeve 6 is fixedly provided on the fixed frame 1, a guide shaft 601 is provided in the guide sleeve 6 for lifting, a mounting seat 5 is fixedly provided at one end of the guide shaft 601 extending out of the guide sleeve 6, the upper pressing wheel 501 is rotatably provided in the mounting seat 5, and an adjusting screw 603 is threadedly connected to the top of the guide sleeve 6, a threaded seat 602 is fixedly provided on the top of the guide sleeve 6, the adjusting screw 603 is threadedly connected to the threaded seat 602, and a disc spring is provided in the guide sleeve 6, and the two ends of the disc spring are respectively connected to the guide sleeve 6. The shaft 601 and the adjusting screw 603 are against each other. When in use, by rotating the adjusting screw 603, under the elastic force of the disc spring, not only the distance between the upper clamping wheel 501 and the lower clamping wheel 401 can be adjusted, which is suitable for use with drive rods 3 of different diameters, but also the clamping force of the upper clamping wheel 501 on the drive rod 3 can be adjusted. While ensuring the reciprocating sliding of the drive rod 3, the shaking of the drive rod 3 is reduced, thereby improving the use effect. Moreover, under the action of the disc spring, the influence of local deformation of the drive rod 3 on the work can be reduced.

[0028] Reference Figure 1 、 Figure 2 and Figure 4 , a limiting frame 7 is fixedly set at one end of the fixed frame 1, and a plurality of limiting rollers 701 are rotatably set in the limiting frame 7, and there are two to eight limiting rollers 701. Here, we prefer six groups, of which four groups have their axes arranged horizontally, two groups are above the driving rod 3, and the other two groups are below the driving rod 3; then the axes of the remaining two groups are arranged vertically, respectively on both sides of the driving rod 3, and the limiting rollers 701 are matched with the driving rod 3. When in use, by fixing the limiting frame 7 on the fixed frame 1 and rotatably setting the limiting rollers 701 in the limiting frame 7, since the length of the driving rod 3 is long, the shaking of the driving rod 3 can be reduced, the contact with the inner wall of the barrel can be reduced, and wear on the inner wall of the barrel or bending of the driving rod 3 can be avoided, thereby improving the service life.

[0029] Reference Figure 2 and Figure 3 A first gear is fixedly provided on the lower pressing wheel 401, and a second gear is fixedly provided on the upper pressing wheel 501, and the first gear is meshed with the second gear. During use, when the first gear and the second gear are in a meshing state, that is, at this time, the diameter of the driving rod 3 is the minimum value of the diameter of the driving rod 3 adapted between the upper pressing wheel 501 and the lower pressing wheel 401. At this time, the driving shaft 4 rotates with the lower pressing wheel 401, which can drive the upper pressing wheel 501 to rotate in the opposite direction, so that it has a certain driving force, which can improve the control effect of the driving rod 3.

[0030] Reference Figure 1 、 Figure 4 and Figure 5A plug-in rod is fixedly provided at one end of the brush head 2, and pin holes are opened at both ends of the driving rod 3, and the plug-in rod is fixedly connected to one end of the driving rod 3 through the pin rod. When the length of the driving rod 3 is not enough, a connecting cylinder 301 can be fixedly provided at the end of the driving rod 3 away from the brush head 2 with a pin rod. A connecting cylinder 301 is also connected to the other set of driving rods 3, and an external thread is fixedly provided at the end of the connecting cylinder 301 away from the driving rod 3. At this time, a threaded cylinder 302 with an internal thread can be used to threadably connect with the two sets of connecting cylinders 301 in sequence to achieve the extension of the driving rod 3. It is easy to disassemble, has a simple structure, and is convenient to carry.
