Description

Technical Field

[0001] The utility model relates to the technical field of gun barrel cleaning, in particular to a gun barrel fixing fixture for a gun cleaning machine. Background Art

[0002] After firing a cannon, since the barrel is in a high-temperature and high-pressure environment, the residues generated by the combustion of gunpowder will adhere to the inner wall of the barrel, forming carbon deposits. If the above residues are not cleaned in time, it will affect the normal movement of the projectile in the barrel, and the barrel will be worn, thereby reducing the shooting accuracy of the cannon. Therefore, a reciprocating gun cleaning machine is usually used to clean the inside of the barrel.

[0003] When using a reciprocating gun cleaning machine, it is usually necessary to use a clamp to fix it on the gun barrel so that the driving rod can slide the brush head back and forth in the gun barrel for cleaning. However, the existing clamp is not only complex in structure and heavy in weight, but also has poor fixing effect, which affects the user experience. Utility Model Content

Therefore, they cannot be understood as limitations on the present invention.

[0023] Example 1:

[0024] Reference Figure 1-Figure 3The gun barrel fixing fixture for the gun cleaning machine includes a fixing plate 1 that is detachably connected to one end of the gun cleaning machine, wherein an avoidance hole is opened on the fixing plate 1, which facilitates the driving rod and brush head of the gun cleaning machine to extend into the gun barrel through the avoidance hole when in use, and a limit block 102 is fixedly provided at the bottom of the fixing plate 1 away from the end of the frame 101. The limit block 102 can play a certain supporting role when the gun cleaning machine is fixed on the fixing plate 1, and can also prevent errors and avoid incorrect installation directions of the fixing plate 1. In addition, a plurality of groups of mounting grooves are opened on the fixing plate 1, and the mounting grooves are provided in two to eight groups, preferably four groups, which are respectively distributed at the top and bottom of the fixing plate 1, and can be reliably connected to the gun cleaning machine by bolts, which is convenient to assemble and disassemble and convenient to carry and store. The two ends of the first splint 2 are respectively fixedly connected to the two groups of frames 101 by bolts, and here, we preferably provide two groups of first splints 2, and a second splint 3 corresponding to the first splint 2 is provided at the top of the frame 101 through a connecting portion. Here, we also provide two groups of second splints 3, and the opposing surfaces of the first splint 2 and the second splint 3 are both arc-shaped structures, which can match the arc surface of the outer wall of the gun barrel, thereby improving the stability during fixation, and the two groups of arc surfaces are respectively against the outer wall of the gun barrel. When in use, by fixing the frame 101 on the fixing plate 1, and providing the first splint 2 and the second splint 3 at the bottom and top of the frame 101 respectively, the gun cleaning machine can be fixedly installed on the gun barrel through the fixing plate 1 during cleaning, which is convenient for cleaning the inside of the gun barrel. Moreover, it has a simple structure, light weight, easy assembly and disassembly, and reliable fixation, which can improve the use effect.

[0025] During use, a frame 101 is fixedly provided on the fixed plate 1, a first clamping plate 2 and a second clamping plate 3 are respectively provided at the bottom and the top of the frame 101, an arc groove 201 is provided on the first clamping plate 2 and the second clamping plate 3, and a clamping pad 402 is provided in the arc groove 201, which not only has an anti-slip effect and improves the stability during clamping, but also reduces the possibility of indentations on the outer wall of the gun barrel, and its structure is simple, light weight, easy to assemble and disassemble, reliable fixation, and can improve the use effect.

[0026] Reference Figure 1-Figure 3, arc grooves 201 are provided on the opposite surfaces of the first plywood 2 and the second plywood 3, that is, arc grooves 201 are provided on the clamping surfaces, and a clamping pad 402 is provided in the arc groove 201, and the clamping end surface of the clamping pad 402 extends out of the arc groove 201. The material of the clamping pad 402 can be rubber, nylon or polyurethane, preferably rubber. When in use, by providing the arc grooves 201 on the first plywood 2 and the second plywood 3 and arranging the clamping pad 402 in the arc groove 201, it can not only have an anti-slip effect and improve the stability during clamping, but also reduce the possibility of indentations on the outer wall of the barrel, thereby improving the use effect.

[0027] Reference Figure 3 A support block 4 is provided in the arc groove 201, and an extension plate 401 is fixedly provided on the inner wall of the support block 4, and the clamping pad 402 is fixedly provided on the inner wall of the extension plate 401, and the extension plate 401 is in an arc-shaped structure. When in use, the clamping pad 402 is installed in the arc groove 201 by using the extension plate 401 and the support block 4, which can reduce the displacement of the clamping pad 402 along the axis direction of the barrel, reduce the movement of the clamping pad 402 in the arc groove 201, and can also increase the contact area between the clamping pad 402 and the outer wall of the barrel through the extension plate 401, thereby further improving the fixing effect.

[0028] Reference Figure 1-Figure 3 Here, we design the connection part as follows: through holes 301 are opened at both ends of the second splint 3, and corresponding threaded holes are opened at the top of the frame 101. The second splint 3 is detachably connected to the frame 101 by bolts. When in use, the through holes 301 are opened on the second splint 3, and the bolts are passed through the through holes 301 and threadedly connected to the threaded holes to fix the second splint 3 on the frame 101. The fixing effect is reliable and the assembly and disassembly is relatively convenient. Moreover, when fixed, the second splint 3 slides vertically relative to the first splint 2, which can reduce deflection and improve the use effect.

[0029] Example 2:

Here, we design the connection part as follows: a rotating shaft 302 is fixedly provided on the top of one set of frames 101, one end of the second splint 3 is rotatably connected to the rotating shaft 302, a screw 5 is rotatably provided on the top of the other set of frames 101, an open groove 303 is provided at the other end of the second splint 3, the end of the screw 5 away from the frame 101 is rotatably provided in the open groove 303, and a hand nut 501 is threadedly connected to the screw 5, and the bottom of the hand nut 501 is screwed in. The end surface of the second splint 3 is against the top end surface of the second open groove 303. When in use, the second splint 3 is rotated to cover the barrel, and then the screw 5 is rotated into the open groove 303, and then the hand nut 501 is tightened to fix the other end of the second splint 3 on the frame 101. At this time, the second splint 3 can clamp the outer wall of the barrel, which can increase the assembly and disassembly speed of the second splint 3, thereby improving the cleaning efficiency. The second splint 3 is connected to the frame 101, which can reduce the time of searching and avoid loss, thereby improving the user experience.
