The front of the inner joint is also provided with a docking hole for inserting a tube, and the external joint is fixedly connected to the external hose.

[0010] Preferably, the L-shaped groove is divided into a vertical portion and a transverse arc-shaped curved portion, and the vertical portion passes through the front side of the docking sleeve to limit the round block from entering the L-shaped groove.

[0011] Preferably, the sealing assembly comprises a limit spring, the limit spring is fixed to the back side of the external joint, and the other end of the limit spring is fixedly connected to a circular ring.

[0012] Preferably, the circular ring is sleeved on the outer surface of the cannula, a sealing ring is provided on the inner annular surface of the circular ring, and the cross section of the sealing ring is T-shaped.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] The pneumatic injection pump with its own emulsified oil tank provides two technical solutions:

[0024] like Figure 1-3 The first embodiment is shown: it includes a pneumatic injection pump body 1 with a protective cover on the outer cover and an external hose 5, an emulsified oil tank 2 is assembled on one side of the pneumatic injection pump body 1, a proportioning device is provided on the pneumatic injection pump 1, the liquid outlet of the emulsified oil tank 2 is connected to the proportioning device, a refueling port 6 is provided on the top of the emulsified oil tank 2, a liquid level gauge 7 is provided on the right side of the emulsified oil tank 2, and a docking mechanism is provided on the high and low pressure water inlet pipes and the air inlet pipe on the pneumatic injection pump body 1, and the docking mechanism includes:

[0025] The docking assembly 3 is used to dock the external hose 5 with the high and low pressure water inlet pipes or air inlet pipes on the pneumatic injection pump body 1. The docking assembly 3 includes an external joint 31 and an internal joint 33. The outer surface of the external joint 31 is fixedly connected with four limiting round blocks 36 at equal distances. The back of the external joint 31 is connected with a plug 32. The front of the internal joint 33 is fixedly connected with a docking sleeve 34. The annular inner surface of the docking sleeve 34 is provided with four L-shaped grooves 35 at equal distances. The inner surface of the internal joint 33 is provided with threads. The internal joint 33 is threadedly connected to the surface of the high and low pressure water inlet pipes or air inlet pipes on the pneumatic injection pump body 1. The front of the internal joint 33 is also provided with a docking hole for inserting the plug 32. The external joint 31 is fixedly connected to the external hose 5. The L-shaped groove 35 is divided into a vertical part and a horizontal arc-shaped curved part, and the vertical part runs through the front of the docking sleeve 34 for limiting the round block 36 to enter the L-shaped groove 35.

[0026] When the external hose 5 is connected, the docking mechanism is used for operation, and only simple operations are required without the need to align the sockets, which greatly increases the convenience of using the device.

[0027] like Figure 2 and3 A second embodiment is shown, which mainly differs from the first embodiment in that a sealing component 4 is arranged on the outside of the insert tube 32, and is used to improve the docking stability between the external joint 31 and the internal joint 33 while performing sealing. The sealing component 4 includes a limit spring 41, and the limit spring 41 is fixed to the back side of the external joint 31. The other end of the limit spring 41 is fixedly connected to a circular ring 42, and the circular ring 42 is sleeved on the outer surface of the insert tube 32. A sealing ring 43 is arranged on the inner annular surface of the circular ring 42, and the cross-section of the sealing ring 43 is T-shaped.

[0028] During docking, the ring 42 and the inner joint 33 are pressed tightly together, so that the stability of docking is ensured and the sealing performance of the insert tube 32 after entering the insertion hole is ensured through the cooperation of the sealing ring 43.

[0029] During docking, align the four limiting round blocks 36 on the external joint 31 with the vertical parts of the four L-shaped grooves 35 on the docking sleeve 34, and insert them after alignment so that the insert tube 32 enters the insertion hole on the external joint 31. During the insertion process, the ring 42 moves and compresses the limiting spring 41, and the limiting round block 36 is inserted into place when it enters the overlapping part of the vertical part and the horizontal arc part of the L-shaped groove 35. At this time, rotate the external joint 31 so that the limiting round block 36 enters the horizontal arc part, thereby completing the docking, and the limiting round block 36 is pressed against the inner wall of the L-shaped groove 35 through the reaction force of the limiting spring 41.
