[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] A novel small-caliber gun bore automatic cleaning device includes a protective sleeve, wherein an activity space 11 is provided inside the protective sleeve 1, and a protective sleeve 2 and an air pipe 12 are respectively installed on the front and rear sides of the activity space 11, and a cylinder 13 is fixedly connected to the side of the activity space 11 close to the air pipe 12, and a fixed sleeve 14 is detachably connected to the output end of the cylinder 13, and a cylinder rod 15 is provided on the front side of the fixed sleeve 14, and the fixed sleeve 14 and the cylinder rod 15 are slidably connected in the activity space 11, and the protective sleeve 2 is provided inside. A cavity 21 is opened, the front end of the cylinder rod 15 extends into the cavity 21 and is provided with a connecting rod 22, the front end of the protective cover 2 is detachably connected with a guide sleeve 31, a rotating mechanism 3 is provided inside the protective cover 2, the connecting rod 22 is detachably connected with a connecting sleeve 32 on the side away from the cylinder rod 15, and a No. 1 rod 33 is detachably connected to the side of the connecting sleeve 32, a plurality of groups of fine-bristle brush heads 34 are installed on the outer surface of the connecting sleeve 32, and a plurality of groups of coarse-bristle brush heads 35 are installed on the outer surface of the No. 1 rod 33.

[0035] The whole product is cylindrical in shape, with dimensions of: diameter 35cm*height 670cm, total weight ≤25KG, working pressure 0.6-1MPa, execution speed ≥10M / Min; the whole product is small in size, easy to carry, and can be operated by one person. It is mainly used for cleaning small-diameter linear gun bores and has a good effect;

[0036] like Figure 1-Figure 2 As shown, the protective cover 1 is detachably connected with the protective cover 2, the connecting cover 32 and the No. 1 rod 33 from the back to the front. In the protective cover 1, the air pipe 12 is installed at the tail of the protective cover 1. The head of the air pipe 12 is connected to the cylinder 13, and the tail of the air pipe 12 is connected to the existing pneumatic high-pressure source. The whole product can use any pneumatic high-pressure source to provide power for the structure.

[0037] like Figure 2 As shown, a fixing sleeve 14 is detachably connected to the front side of the cylinder 13, a cylinder rod 15 is installed on the front side of the fixing sleeve 14, and there is a distance between the fixing sleeve 14 and the cylinder rod 15, wherein an activity space 11 is opened inside the protective sleeve 1, and the activity space 11 is a sealed space. When the air pipe 12 is venting, the cylinder 13 pushes the fixing sleeve 14 to move in the activity space 11, and the fixing sleeve 14 squeezes the air to make the cylinder rod 15 also move in the activity space 11. Conversely, when the air pipe 12 is inhaling, the fixing sleeve 14 and the cylinder rod 15 move in the initial direction under the action of negative pressure, so that the fixing sleeve 14 and the cylinder rod 15 can move back and forth in the activity space 11;

[0038] like Figure 2-Figure 3As shown, in the protective sleeve 2, a cavity 21 is opened inside the protective sleeve 2, a connecting rod 22 is arranged at the center of the cavity 21, a guide sleeve 31 is installed on the front side of the protective sleeve 2, the inner side of the guide sleeve 31 is fixedly connected to the outer surface of the connecting rod 22, wherein the cylinder rod 15 first penetrates the activity space 11 and extends into the cavity 21, and the cylinder rod 15 first part is detachably connected to the connecting rod 22, so when the cylinder rod 15 moves, the cylinder rod 15 can drive the connecting rod 22 to move in the cavity 21, and the connecting rod 22 drives the guide sleeve 31 to move synchronously;

[0039] like Figure 2 As shown, a rotating mechanism 3 is provided inside the protective cover 2, and the rotating mechanism 3 is used to drive the connecting rod 22 to rotate inside the protective cover 2, and cooperate with the push of the cylinder 13 to enable the connecting rod 22 to achieve the effect of rotating and moving at the same time, as shown in FIG. Figure 2-Figure 3 As shown, one end of the connecting rod 22 away from the cylinder rod 15 is threadedly connected to the connecting sleeve 32, and the No. 1 rod 33 is arranged at the end of the connecting sleeve 32 away from the connecting rod 22, wherein a plurality of groups of fine-bristle brush heads 34 are evenly and evenly distributed on the outside of the connecting sleeve 32, and a plurality of groups of coarse-bristle brush heads 35 are evenly and evenly distributed on the outside of the No. 1 rod 33, the connecting sleeve 32 and the No. 1 rod 33 are on the same axis, and the connecting sleeve 32 moves synchronously with the connecting rod 22, the No. 1 rod 33 is detachably connected to the connecting sleeve 32, and the No. 1 rod 33 also moves synchronously with the connecting rod 22.

[0040] In this embodiment, Figure 4 As shown, the spiral groove 36 is formed on the inner wall of the protective sleeve 2. Figure 5-Figure 6 As shown, the spherical screw 37 is composed of a ring and a ball. The inner side of the ring is fixedly connected to the outer surface of the connecting rod 22, the top of the ball is fixedly connected to the lowest end of the ring, and the bottom of the ball is located inside the spiral groove 36. When the cylinder rod 15 drives the connecting rod 22 to move, the connecting rod 22 moves the ball along the spiral groove 36 through the ring. Due to the rotational connection between the connecting rod 22 and the cylinder rod 15, as the cylinder rod 15 reciprocates, the connecting rod 22 also reciprocates inside the protective cover 2, thereby causing the connecting rod 22 to drive the fine-bristle brush head 34 and the coarse-bristle brush head 35 to reciprocate, thereby improving the cleaning effect of the gun barrel.

[0041] In this embodiment, Figure 8 As shown, a moving space 5 is opened inside the connecting sleeve 32, and the head of the first rod 33 and the tail of the second rod 51 are located in the moving space 5 and are on opposite sides; Figure 2-Figure 3 As shown, the cylinder rod 15, the connecting rod 22 and the second rod 51 are all provided with slots at their axis. After assembling the various structures, the multiple slots are interconnected to form a mounting hole, and then the hard tube 52 is inserted into the mounting hole. Then, the first rod 33 and the connecting sleeve 32 are assembled, and the first part of the hard tube 52 is inserted into the first rod 33, so as to seal the first part of the hard tube 52. Figure 4-Figure 7As shown in the figure, a first groove 53 is formed inside the cylinder rod 15. The two port ends of the first groove 53 are respectively communicated with the tail of the hard pipe 52 and the movable pipe 54. The tail of the movable pipe 54 is communicated with the air pipe 12. When the air pipe 12 discharges air, part of the gas enters the hard pipe 52 through the movable pipe 54 and the first groove 53. On the contrary, when the air pipe 12 inhales air, the gas in the hard pipe 52 returns to the air pipe 12 through the movable pipe 54 and the first groove 53.

[0042] As Figure 1-Figure 4 shown, the protective sleeve 2 is arranged in a double-shell structure, which is divided into an outer shell and an inner shell. There is a spacing between the outer shell and the inner shell, and this spacing is called the transition space. The spiral groove 36 is formed on the surface of the inner shell of the protective sleeve 2. A plurality of ventilation grooves 57 are formed on the surface of the outer shell of the protective sleeve 2. The ventilation grooves 57 are arranged around the axis of the protective sleeve 2 and are also communicated with the transition space. The rubber film 58 wraps all the ventilation grooves 57 and is located outside the ventilation grooves 57. The edge of the rubber film 58 is detachably connected to the outer surface of the outer shell of the protective sleeve 2. A plurality of ventilation holes 38 are formed on the movable pipe 54, and the ventilation holes 38 are located in the transition space. When the hard pipe 52 discharges air, the gas is transported into the transition space through the ventilation holes 38, and then through the ventilation grooves 57, so that the rubber film 58 expands outwards. The expanded rubber film 58 is spherical in shape. On the contrary, when the hard pipe 52 inhales air, the rubber film 58 resumes its shape. The intermittent expansion and contraction of the rubber film 58 produce a peristaltic effect, which helps to push the whole product to move. At the same time, a control valve is arranged at the connection between the movable pipe 54 and the air pipe 12, and a camera is arranged on the first rod 33. If a large amount of residues are found at a certain place on the inner wall of the gun barrel by the camera, the camera feeds back to the control valve, and the control valve closes the port at the tail of the movable pipe 54, so that the rubber film 58 is filled, and the rubber film 58 keeps in contact with the inner wall of the gun barrel. By increasing the friction force, the movement of the whole product is slowed down or paused, and the cleaning time of the thick brush head 35 and the fine brush head 34 on a certain place of the inner wall of the gun barrel is extended, which is beneficial to improving the cleaning effect of the gun barrel.

[0043] In this embodiment, as Figure 6-Figure 7 shown, the movable pipe 54 is composed of a first pipe 9, a hose 91 and a second pipe 92. Among them, the first pipe 9 is detachably connected to the first groove 53. The shape of the second pipe 92 is set as a U shape. The port at one folding corner of the second pipe 92 is communicated with the air pipe 12, and the other folding corner is located in the transition space. The ventilation hole 38 is arranged at this folding corner. At the same time, the port at this folding corner penetrates through the inner shell of the protective sleeve 2 and is connected to the hose 91. The other end port of the hose 91 is connected to the port of the first pipe 9. The hose 91 has flexibility and elasticity, so as to ensure the normal movement of the cylinder rod 15 in the protective sleeve 2.

[0044] In this embodiment, as Figure 8As shown, the third slot 6 is opened at the tail of the second rod 51, the push plate 61 is sleeved on the outer surface of the hard tube 52, the outer side of the push plate 61 slides along the inner wall of the third slot 6, and the inner side of the push plate 61 slides along the outer side of the hard tube 52. A plurality of exhaust slots 62 are arranged between the rear side of the push plate 61 and the side wall of the second slot 56. The plurality of exhaust slots 62 are evenly arranged around the outer side of the hard tube 52, and a plurality of push rods 63 are evenly fixedly connected to the front side of the push plate 61. When the hard tube 52 transports gas outward through the exhaust slots 62, the gas will push the push plate 61 to move inside the third slot 6, and the push rods 63 will also move synchronously with the push plate 61; as shown in FIG. Figure 3 and Figure 8 As shown, a plurality of slide grooves 67 are provided on the outer surface of the connecting sleeve 32, and a mounting plate 65 is correspondingly slidably connected in each slide groove 67. The length of the slide groove 67 is greater than the length of the mounting plate 65, so the mounting plate 65 can be offset forward and backward in the slide groove 67. A protruding block 64 is fixedly connected to the inner side of the mounting plate 65, and the end of the protruding block 64 extends into the moving space 5. A plurality of protruding blocks 64 are evenly distributed around the tail of the No. 1 rod 33, and the end of the push rod 63 contacts the protruding block 64. A return spring 66 is provided on the side of the protruding block 64 away from the push rod 63. The reset spring 66 is sleeved at the tail of the No. 1 rod 33. When the push rod 63 moves, the push rod 63 drives the mounting plate 65 to move in the slide groove 67 through the protruding block 64. On the contrary, when the hard tube 52 inhales air, the push plate 61 loses the extrusion force. Under the action of the reset spring 66, all structures inside and outside the connecting sleeve 32 return to the initial position. The fine-bristle brush head 34 is detachably connected to the outer surface of the mounting plate 65. The fine-bristle brush head 34 reciprocates with the mounting plate 65 on the outside of the connecting sleeve 32, which is beneficial to improve the cleaning effect of the cleaning device on the inner wall of the gun barrel.

[0045] In this embodiment, Figure 3 As shown and Figure 9-10As shown, multiple groups of bases 7 are arranged at intervals around the outer side of the No. 1 rod 33 to form base 7 rings, and multiple base 7 rings are arranged at equal intervals at the head of the No. 1 rod 33. The shape of the base 7 is set to be L-shaped, and the arc plate 71 is set on the rear side of the horizontal part of the base 7. The side plates 72 are fixedly connected to the left and right sides of the arc plate 71. The base 7, the arc plate 71 and the side plates 72 are surrounded to form a material receiving space. The top of the material receiving space is open, and the rubber ring 73 is sleeved on the ground of the material receiving space. The rubber ring 73 fixes the tail of the coarse-bristled brush head 35 to the upper surface of the base 7, and the head of the coarse-bristled brush head 35 extends out of the material receiving space. When the coarse-bristled brush head 35 removes residues, the residues fall directly or slide along the inner wall of the barrel to the barrel. The lowest end of the barrel, thereby causing a large amount of residue to accumulate at the lowest end of the barrel. The accumulated residue will affect the coarse-bristled brush head 35 in performing preliminary rough cleaning of the inner wall of the lowest end of the barrel, so a material receiving space is set around the coarse-bristled brush head 35. When removing the residue, part of the residue falls into the material receiving space, reducing excessive accumulation of residue at the lowest end of the barrel, which is beneficial to improving the cleaning effect of the coarse-bristled brush head 35. At the same time, the top of the arc plate 71 is bent toward the vertical part of the base 7 to narrow the top opening of the material receiving space. The distance from the top of the arc plate 71 to the coarse-bristled brush head 35 is smaller than the distance from the middle part of the arc plate 71 to the coarse-bristled brush head 35, so that the top of the arc plate 71 blocks the residue from flowing out of the material receiving space.

[0046] In this embodiment, Figure 9-10 As shown, long plate 74 No. 1 is located between adjacent bases 7, and the left and right sides of long plate 74 No. 1 are fixedly connected to adjacent side plates 72 respectively, and long plate 74 No. 1 is connected to side plates 72 on base rings at different positions, and at the same time, arc plate 71 is rotatably connected to the tail of the lateral part of base 7, and a torsion spring is installed at the rotating part, and a disc protrusion is arranged on the outer side of rod 33, and the disc protrusion is arranged on the side of rod 33 No. 1 close to the connecting sleeve 32, and a plurality of notches are arranged on the front side of the disc protrusion, which are engaged with the tail of long plate 74 No. 1; the head of long plate 74 No. 1 is pushed, so that long plate 74 No. 1 drives side plates 72 to move backward, thereby causing arc plate 71 to rotate backward, thereby expanding the top opening of the material receiving space, facilitating regular cleaning of residues in the material receiving space, and facilitating replacement of rubber rings and coarse-bristled brush heads 35.

[0047] In this embodiment, Figure 10-11As shown, the front side of the blocking plate 75 is set to a sawtooth shape, and the sawtooth depression is embedded in the coarse-bristled brush head 35, and the sawtooth protrusion is detachably connected to the side wall of the base 7. The rear side of the blocking plate 75 is set to an arc shape, and the end of the arc is bent toward the bottom surface of the material receiving space. The end of the arc always maintains a distance with the arc plate 71, and the distance is called the feed port. The blocking plate 75 divides the material receiving space into a dynamic space and a static space. The dynamic space is above the blocking plate 75, and the static space is below the blocking plate 75. The residue moves along the blocking plate 75 and slides into the static space through the feed port. When the coarse-bristled brush head 35 is in operation, the residue is blocked by the blocking plate 75 and retained in the static space, thereby further improving the collection effect of the material receiving space. At the same time, as shown in Fig. 9 As shown, a second long plate 76 is provided on both sides of the blocking plate 75, and an arc groove 77 is opened in the side plate 72. The second long plate 76 is slidably connected in the arc groove 77. When the first long plate 74 is pushed, the first long plate 74 drives the arc plate 71 to rotate through the side plate 72, so that the second long plate 76 moves relatively in the arc groove 77, so that the feed port is opened, which is convenient for cleaning the residue in the static space. At the same time, the serrated part of the blocking plate 75 can be removed from the side wall of the base 7, so that the blocking plate 75 and the arc plate 71 move synchronously, so that the bottom surface of the material receiving space is opened, which is convenient for replacing the rubber ring 73 and the coarse-bristled brush head 35.

[0048] In this embodiment, Fig.12 As shown, a groove 84 is provided on the outer side of the first part of the rod 33, a rubber layer 85 is arranged around the outer end of the groove 84, the edge of the rubber layer 85 is fixedly connected to the side wall of the groove 84, and the rubber layer 85 and the groove 84 form an elastic space. At the same time, an exhaust channel 83 is provided at the axis of the first rod 33, and the tail of the exhaust channel 83 is connected to the first part of the hard tube 52. A plurality of air leakage holes 86 are provided on the inner wall of the exhaust channel 83, and the air leakage holes 86 connect the exhaust channel 83 with the elastic space; the end of the connecting column 87 is fixedly connected to the bottom surface of the groove 84, and the side of the connecting column 87 is fixedly connected to the rubber layer 85, and the plurality of connecting columns 87 connect the various parts of the rubber layer 85 The top of the connecting column 87 is connected to the groove 84, which is convenient for the various parts of the rubber layer 85 to expand or shrink synchronously. The top of the connecting column 87 is detachably connected to the bottom of the base 7, and the top of the connecting column 87 can also move up and down in a small range on the bottom of the base 7. The top of the connecting column 87 does not penetrate the bottom of the base 7; when the hard tube 52 transports gas to the exhaust channel 83, the gas moves from the exhaust channel 83 to the elastic space through the vent hole 86, so that the entire elastic space expands outward, and the rubber layer 85 will push the base 7 to move outward along the top of the connecting column 87, so that the top of the coarse-bristled brush head 35 on the base 7 is in close contact with the inner wall of the barrel, further improving the cleaning effect of the cleaning device.

[0049] In this embodiment, Fig.12As shown, a disc protrusion is arranged on the outer side of the No. 1 rod 33, and the disc protrusion is located on the side of the No. 1 rod 33 close to the connecting sleeve 32. The control disk 8 is rotatably connected at the middle part of the disc protrusion. A notch is provided at the center of the control disk 8, and the notch is connected to the exhaust passage 83. A placement groove 81 is arranged above the notch, and the placement groove 81 is arranged inside the control disk 8. The top of the sealing block 82 is slidably connected in the placement groove 81, and the bottom of the sealing block 82 is round, and the sealing block 82 can be hidden in the placement groove 81; the control disk 8 is rotated to make the sealing block 82 slide into The sealing block 82 is placed in the groove 81, so that the groove at the center of the control disk 8 is open, so that the gas in the hard tube 52 is transported to the exhaust channel 83. On the contrary, the control disk 8 is rotated in the opposite direction. Under the action of gravity, the sealing block 82 slides out of the placement groove 81, and the outer contour of the bottom of the sealing block 82 contacts the inner wall of the groove at the center of the control disk 8, thereby blocking the gas in the hard tube 52 from entering the exhaust channel 83. Therefore, when the elastic space is filled with suitable gas, the control disk 8 is rotated to keep the elastic space in the state without being affected by the intermittent air intake or exhaust of the hard tube 52.

[0050] It should be noted that the present invention is a novel small-caliber gun bore automatic cleaning device. When used, Figure 1-Figure 6 As shown, the pneumatic high-pressure source is started, and the gas provides power to the cylinder 13 through the air pipe 12, so that the cylinder 13 pushes the fixed sleeve 14 to reciprocate in the activity space 11. When the fine-bristle brush head 34 and the coarse-bristle brush head 35 are inserted into the muzzle, the bristles on the fine-bristle brush head 34 fall toward the muzzle, and the same is true for the bristles on the coarse-bristle brush head 35. The fine-bristle brush head 34 and the coarse-bristle brush head 35 rub against the inner wall of the barrel at high speed, and under the axial push of the cylinder 13, the entire product moves along the barrel toward the tail of the gun; wherein the cylinder 13 drives the connecting rod 22 to move through the fixed sleeve 14 and the cylinder rod 15, and the connecting rod 22 drives the fine-bristle brush head 34 and the coarse-bristle brush head 35 to move through the connecting sleeve 32 and the No. 1 rod 33 respectively. When the fine-bristle brush head 34 reaches the end of the muzzle, the air pipe 1 is manually pulled. 2 moves outward, so that the bristles on the fine brush head 34 face the initial direction, and the bristles on the coarse brush head 35 also face the initial direction, thereby changing the force direction of the fine brush head 34 and the coarse brush head 35, and under the axial power of the cylinder 13, the entire device moves in the opposite direction until it returns to the starting point of the initial cleaning, thereby completing the first gun barrel cleaning, the fine brush head 34 and the coarse brush head 35 rub against the inner wall of the gun barrel respectively, and remove the residue attached to the inner wall of the gun barrel, and the residue is pushed out from the gun muzzle with the movement of the fine brush head 34 and the coarse brush head 35, wherein the coarse brush head 35 is responsible for the preliminary rough cleaning of the inner wall of the gun barrel, and the fine brush head 34 is responsible for the precise cleaning of the inner wall of the gun barrel, thereby realizing the cleaning of the inner wall of the gun barrel and the removal of gunpowder residue, saving time and effort and simple operation;

[0051] like Figure 2 As stated and Figure 4-Figure 6As shown, during the reciprocating motion of the connecting rod 22, the connecting rod 22 reciprocates in the protective cover 2 through the rotating mechanism 3, so that the connecting rod 22 drives the fine-bristle brush head 34 and the coarse-bristle brush head 35 to reciprocate in the bore through the connecting cover 32 and the No. 1 rod 33, respectively, so as to clean all directions of the inner wall of the bore, which is beneficial to improve the cleaning effect of the bore.
