Description

Technical Field

[0001] The utility model relates to the technical field of vibration pumps, in particular to a vibration pump and a brush thereof. Background Art

[0002] During the firing process of the artillery, gunpowder residues, copper and plastic will remain on the inner wall of the barrel. After each round of shooting, the barrel of the artillery needs to be wiped and maintained. Manual wiping is time-consuming and labor-intensive. Automatic wiping has replaced manual wiping and has become a trend. Automatic wiping is divided into electric and pneumatic. The advantages of pneumatic over electric are mainly concentrated in high wiping efficiency and convenient air intake from vehicles. In pneumatic wiping, high-pressure gas is used as the power source. The high-pressure gas source drives the piston rod back and forth through the air intake line inside the piston cylinder. The vibration pump composed of the piston cylinder and the piston rod generates overall vibration, which generates lateral amplitude after vibration. The lateral amplitude cooperates with the wiping brush head to form a lateral displacement. Since the wiping brush head is fixed on the vibration pump, it drives the wiping brush head forward or backward in the barrel of the artillery. After repeated wiping, the wiping and maintenance of the artillery barrel are completed.

[0003] During the wiping process, if the vibration pump is still in the gun barrel and the air supply is suddenly cut off, the piston rod will stay in the equilibrium position of the piston cylinder. When the air is supplied again, since the piston rod stays in the equilibrium position of the piston cylinder, the high-pressure gas will leak out from the exhaust hole at the matching gap between the piston rod and the piston cylinder, causing the piston rod to be unable to move, so that the vibration pump cannot work normally, which causes the wiping brush head to get stuck in the gun barrel, making it difficult to move forward or backward, affecting the wiping efficiency and inconvenience in use.

[0004] Based on this, it is necessary to provide a vibration pump and its brush to address the problem that when the air source is cut off, the piston rod stays in the equilibrium position of the piston cylinder, causing the vibration pump to fail to work normally.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time.

[0023] like Figure 1 As shown, an embodiment of the utility model proposes a brush, which includes a vibration pump and a brush head part, and the brush head part is divided into an existing structure. The vibration pump is used to provide power to the brush to drive the brush head part to vibrate. The vibration pump includes: a piston cylinder 1, a piston rod 2, a cover plate 3, an elastic part 4 and an air intake pipe 16. Among them, the piston cylinder 1 mainly plays a role of installation, and the piston rod 2 mainly plays a role of generating vibration. The cover plate 3 mainly plays a sealing role. The elastic part 4 mainly plays a resetting role. The air intake pipe 16 mainly plays a role of transmitting a high-pressure gas source. It should be noted that in this embodiment, the piston cylinder 1 and the piston rod 2 are both rotating body structures.

[0024] Specifically, a first connecting port 11 and a second connecting port 12 are respectively provided at both ends of the piston cylinder 1, a chamber 13 is provided inside the piston cylinder 1, and the chamber 13 is connected to the second connecting port 12, and a first exhaust hole 14 and a second exhaust hole 15 are respectively provided near the first connecting port 11 and the second connecting port 12, and the first exhaust hole 14 and the second exhaust hole 15 are both connected to the chamber 13.

[0025] Among them, the first connection port 11 is mainly used to connect with the pipeline of the external high-pressure gas source. The second connection port 12 mainly plays the role of avoidance and easy installation. The corresponding parts, such as the piston rod 2 and the elastic member 4, can be installed in the chamber 13 in the piston cylinder 1 through the second connection port 12. The piston rod 2 is slidably arranged in the chamber 13. The reciprocating movement of the piston rod 2 in the chamber 13 will cause the vibration pump to generate a lateral amplitude. The lateral amplitude cooperates with the brush head part to form a lateral displacement, so that the inner wall of the barrel can be cleaned. The first exhaust hole 14 and the second exhaust hole 15 mainly play the role of exhaust.

[0026] In addition, an annular groove 17 is provided in the piston cylinder 1 and communicates with the chamber 13. One end of the air intake pipe 16 communicates with the first connection port 11, and the other end of the air intake pipe 16 communicates with the annular groove 17. In other words, an external high-pressure gas source can enter the air intake pipe 16 through the first connection port 11, and then enter the annular groove 17 through the other end of the air intake pipe 16. Since the annular groove 17 is communicated with the chamber 13, the high-pressure gas source can cooperate with the piston rod 2 in the chamber 13 to drive the piston rod 2 to move in the chamber 13.

[0027] The cover plate 3 is connected to one end of the piston cylinder 1 near the second connection port 12 to seal the second connection port 12. The cover plate 3 is used to seal the second connection port 12, so that the high-pressure gas source entering the chamber 13 can only be discharged from the first exhaust hole 14 or the second exhaust hole 15, reducing the loss of the high-pressure gas source, so that the piston rod 2 can perform normal reciprocating motion.

[0028] The elastic member 4 is arranged between the piston rod 2 and the cover plate 3, so as to push one end of the piston rod 2 to contact with the inner wall of the chamber 13 away from the cover plate 3 when no gas enters the chamber 13. The elastic member 4 may be a spring. That is to say, when the vibration pump is not working, that is, when the high-pressure gas source is cut off, the end of the piston rod 2 close to the first connecting port 11 will always fit with the inner wall of the chamber 13 under the action of the elastic member 4, so as to avoid the piston rod 2 being in the middle position of the chamber 13, that is, the equilibrium position, so that the high-pressure gas source entering the chamber 13 will not be discharged from the first exhaust hole 14 and the second exhaust hole 15 at the same time, and then a pressure difference can be generated at both ends of the piston rod 2, so that the piston rod 2 can move back and forth.

[0029] Specifically, in the non-working state, that is, when the high-pressure gas source is cut off, the piston rod 2 is pressed by the elastic member 4, and the end of the piston rod 2 close to the first connection port 11 will fit against the inner wall of the chamber 13. When the piston rod 2 is in this position, the first exhaust hole 14 is in a closed state, the second exhaust hole 15 is in an open state, and the annular groove 17 is in a connected state with the first air inlet 221, and the annular groove 17 is in a disconnected state with the second air inlet 231.

[0030] In the working state, that is, when a high-pressure gas source is introduced, the high-pressure gas source will sequentially pass through the intake pipeline 16, the annular groove 17, and the first intake port 221 and enter into the first intake groove 22. Under the action of the high-pressure gas source, the piston rod 2 will move towards the second connection port 12. When the piston rod 2 moves to the preset critical point, at this time, the second exhaust hole 15 is in the closed state, the first exhaust hole 14 is in the open state, and the annular groove 17 is in communication with the second intake port 231, and the annular groove 17 is disengaged from the first intake port 221. Thus, under the action of the high-pressure gas source, the piston rod 2 will move towards the first connection port 11 again. At this time, the high-pressure gas source in the first intake groove 22 will flow into the chamber 13 from the first outlet 222, and then be discharged from the first exhaust hole 14. Similarly, when the piston rod 2 moves towards the second connection port 12 again, the high-pressure gas source in the second intake groove 23 will flow into the chamber 13 from the second outlet 232, and then be discharged from the second exhaust hole 15. The piston rod 2 acts in this cycle, and the vibration pump can generate a continuous amplitude.

[0031] In addition, the annular groove 17 communicates with the middle position of the chamber 13. That is to say, the annular groove 17 is located in the middle of the chamber 13, so that the distances between the annular groove 17 and the two sides of the chamber 13 are the same, which is convenient for the high-pressure gas source entering the chamber 13 from the intake pipeline 16 through the annular groove 17 to move towards the first connection port 11 side or the second connection port 12 side.

[0032] In addition, the structure of the cover plate 3 is a C-shaped structure, and the opening faces the second connection port 12. A first connection part is arranged on the inner side wall of the cover plate 3, and a second connection part is arranged on the outer wall of the piston barrel 1 close to the second connection port 12, and the first connection part is connected to the second connection part.

[0033] Among them, the structure of the cover plate 3 is designed as a C-shaped structure, which is easier to be connected and matched with the piston barrel 1. The first connection part can be an internal thread, and the second connection part can be an external thread. Through the connection and cooperation between the internal thread and the external thread, the cover plate 3 can be connected to the piston barrel 1, so as to seal the second connection port 12, reduce the leakage of the high-pressure gas source, and the loading and unloading are also relatively convenient. Of course, the first connection part and the second connection part can also be the existing buckle and groove structures.

[0034] Furthermore, a card slot 31 is provided on the inner side wall of the cover plate 3, and the card slot 31 is arranged close to the first connecting part. A seal 7 is arranged inside the card slot 31 to seal the gap between the first connecting part and the second connecting part. The seal 7 mainly plays a sealing role. The card slot 31 is arranged close to the first connecting part, so that when the seal 7 is installed in the card slot 31, the gap between the first connecting part and the second connecting part can be sealed, thereby preventing the high-pressure gas source inside the chamber 13 from leaking from the gap between the first connecting part and the second connecting part, which is beneficial to the normal operation of the piston rod 2. The seal 7 and the card slot 31 can both be annular structures.

[0035] In addition, a convex rod 32 is provided on the bottom wall of the cover plate 3 facing the elastic member 4, and one end of the elastic member 4 close to the cover plate 3 is sleeved on the convex rod 32. Among them, the convex rod 32 mainly plays a supporting and limiting role. The end of the elastic member 4 close to the cover plate 3 is sleeved on the convex rod 32, so that the convex rod 32 can support and limit one end of the elastic member 4, so that when the elastic member 4 performs a telescopic action in the chamber 13, the deformation of the elastic member 4 in the direction perpendicular to the telescopic direction can be reduced, so that the elastic member 4 can be protected, so that the elastic member 4 can work normally, and the service life of the elastic member 4 can be extended.

[0036] In addition, a limiting groove 21 is provided on the outer wall of the piston rod 2 near the cover plate 3, and the other end of the elastic member 4 is sleeved in the limiting groove 21. The limiting groove 21 mainly plays a limiting role. The other end of the elastic member 4 is sleeved in the limiting groove 21, so that the limiting groove 21 can be used to limit the other end of the elastic member 4 in a direction perpendicular to the telescopic direction, and the piston rod 2 can be used to support the other end of the elastic member 4. In this way, the deformation of the elastic member 4 in the direction perpendicular to the telescopic direction can be further reduced, the elastic member 4 can be protected, the elastic member 4 can be allowed to work normally, and the service life of the elastic member 4 can be extended.

[0037] Furthermore, a first air inlet groove 22 is opened on the outer wall of the piston rod 2 on the side close to the first connecting port 11, and a second air inlet groove 23 is opened on the outer wall of the piston rod 2 on the side close to the second connecting port 12. The first air inlet groove 22 and the second air inlet groove 23 both extend along the length direction of the piston rod 2, and the ends of the first air inlet groove 22 and the second air inlet groove 23 close to each other are both connected to the chamber 13.

[0038] The first air inlet groove 22 mainly serves as an air intake. The first air inlet groove 22 is arranged on the outer wall of the piston rod 2 near the first connection port 11, so that when the high-pressure air source is charged into the chamber 13, and the first exhaust hole 14 is in a closed state, and the second exhaust hole 15 is in an open state, the high-pressure air source will be charged into the side of the piston rod 2 near the first connection port 11, and then enter the first air inlet groove 22, making it easier to push the piston rod 2 to move toward the second connection port 12.

[0039] Similarly, the second air inlet groove 23 mainly serves the purpose of air intake. The second air inlet groove 23 is arranged on the outer wall of the piston rod 2 on the side close to the first connection port 11, so that when the first exhaust hole 14 is in an open state and the second exhaust hole 15 is in a closed state, the high-pressure air source will automatically fill the side of the piston rod 2 close to the second connection port 12, and then enter the second air inlet groove 23, making it easier to push the piston rod 2 to move toward the first connection port 11.

[0040] In addition, the first connection port 11 is connected with a quick connector 5. The quick connector 5 mainly serves as a connection. The quick connector 5 can quickly connect the external high-pressure gas source pipeline to the first connection port 11, which is more convenient to use and has good sealing performance.

[0041] In addition, a third connection portion 6 is provided on the side of the cover plate 3 facing away from the piston cylinder 1. The third connection portion 6 mainly plays a connecting role, and the third connection portion 6 can be connected to the brush head part, so that when the vibration pump vibrates, the vibration pump can transmit the vibration to the brush head part, so that the inner wall of the gun barrel can be cleaned.
