[0004] The above-mentioned pneumatic connectors are connected to the corresponding pipe fittings by insertion. Therefore, during installation and disassembly, it is only necessary to insert or pull them out with force. During installation, it may be possible that the connector is not inserted to the bottom, resulting in a loose connection. Furthermore, when the pneumatic connector is working, accidental contact by external personnel may cause the pneumatic connector to be loosely connected to the corresponding pipe, thereby leading to gas leakage. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the connection between existing pneumatic connectors and corresponding pipe fittings is through an insertion method. Therefore, force is required to insert or pull them out during installation and disassembly. During installation, it may be possible for the connector not to be inserted to the bottom, resulting in a loose connection. Furthermore, when the pneumatic connector is in operation, accidental contact by external personnel may cause the pneumatic connector to be loosely connected to the corresponding pipe, leading to gas leakage. This utility model proposes a pneumatic connector structure with stable and rapid airflow.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The pneumatic connector structure of this utility model with stable and rapid airflow includes a connector head, one end of which is fixedly connected to an air inlet, and the other end of which is fixedly connected to a connection port. The connection port has a thread on its outer side. An air inlet head is provided inside the air inlet. A fixing mechanism is provided inside the air inlet. Two sets of fixing mechanisms are provided. The fixing mechanisms are located on both sides inside the air inlet. The fixing mechanism includes a through groove, which is opened inside the air inlet. An L-shaped groove is opened at one end of the through groove. A locking block is fixedly connected to the outer side of the air inlet head. The locking block is inside the L-shaped groove.

[0007] Preferably, the dimensions of the through groove and the L-shaped groove are the same, and the dimensions of the locking block are adapted to the through groove and the L-shaped groove.

[0008] Preferably, the air inlet has two sets of movable slots inside, with long rods fixedly connected to both ends inside the movable slots. Movable blocks are sleeved on the outside of the long rods. A backing plate is provided inside the air inlet, with the outside of the backing plate fixedly connected to the two sets of movable blocks. One side of the backing plate is in close contact with the air inlet head.

[0009] Preferably, a spring is sleeved on the outside of the long rod, and the two ends of the spring are fixedly connected to one end of the moving block and the moving groove.

[0010] Preferably, a sealing block is provided inside the through groove, and the sealing block is fixedly connected to the outside of the abutment plate.

[0011] Preferably, a sealing ring is fixedly connected to the side of the abutment near the air inlet head, and a sealing ring is fixedly connected to the side of the connection port.

[0012] The advantages of this utility model are:

[0013] This utility model, through the structural design of the fixing mechanism, achieves the function of fixing the air inlet head by having the locking block on the outside of the air inlet head enter the through groove and L-shaped groove opened inside the air inlet at one end of the connector head. At this time, it will press against the back plate and compress the spring. After rotating the air inlet head appropriately, the locking block enters the middle of the L-shaped groove and the air inlet is released. At this time, the compressed spring will pop out the back plate and make the locking block enter the L-shaped groove. In this way, the air inlet head is fixed and cannot be pulled out further. This solves the problem that the connection between the pneumatic connector and the corresponding pipe is a plug-in connection, so it is necessary to force to insert or pull out during installation and disassembly. During installation, it may not be inserted to the bottom, resulting in a loose connection. In addition, when the pneumatic connector is working, accidental contact by outsiders may loosen the connection between the pneumatic connector and the corresponding pipe, resulting in gas leakage.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0021] Please see Figure 1 - Figure 4 As shown, a pneumatic connector structure for stable and rapid airflow includes a connector 1, one end of which is fixedly connected to an air inlet 2, and the other end of which is fixedly connected to a connection port 3. The connection port 3 has a thread on its outer side. An air inlet head 4 is provided inside the air inlet 2. A fixing mechanism is provided inside the air inlet 2. Two sets of fixing mechanisms are provided. The fixing mechanisms are located on both sides inside the air inlet 2. The fixing mechanism includes a through groove 5, which is opened inside the air inlet 2. An L-shaped groove 6 is opened at one end of the through groove 5. A locking block 7 is fixedly connected to the outer side of the air inlet head 4. The locking block 7 is inside the L-shaped groove 6.

[0022] During operation, the connector 1's connector port 3 is threadedly connected to the corresponding device that requires gas entry. After the connector 1 is installed, the locking blocks 7 on both sides of the gas inlet head 4 are aligned with the through groove 5 opened inside the gas inlet 2 at one end of the connector 1, and the gas inlet head 4 is inserted into the gas inlet 2. At this time, the locking blocks 7 enter the through groove 5. When the locking blocks 7 enter the through groove 5, one end of the gas inlet head 4 is pressed against the abutment plate 11 and pushed into the gas inlet 2. The sealing block 13 entering the through groove 5 does not affect the locking blocks 7 entering the L-shaped groove 6. At this time, the spring 12 is compressed. The gas inlet head 4 is rotated correctly and appropriately so that the locking blocks 7 enter the L-shaped groove 6. The compressed spring 12 of the gas inlet head 4 is released, and the abutment plate 11 is pushed outward. At this time, the locking blocks 7 enter the L-shaped groove 6. At this time, the tendency of the abutment plate 11 to continue to push outward is blocked, so the gas inlet head 4 cannot be pulled out further and reaches a fixed state.

[0023] Furthermore, such as Figure 2 and Figure 4 As shown, the dimensions of the through groove 5 and the L-shaped groove 6 are the same, and the dimensions of the locking block 7 are adapted to the through groove 5 and the L-shaped groove 6;

[0024] During operation, the dimensions of the through groove 5, the L-shaped groove 6, and the locking block 7 are all compatible, so the locking block 7 can smoothly enter the through groove 5 and the L-shaped groove 6, thereby completing the installation of the connector 1 and the air inlet head 4.

[0025] Furthermore, such as Figure 4 As shown, the air inlet 2 has two sets of movable slots 8 inside. Long rods 9 are fixedly connected to both ends inside the movable slots 8. Movable blocks 10 are sleeved on the outside of the long rods 9. A backing plate 11 is provided inside the air inlet 2. The outside of the backing plate 11 is fixedly connected to the two sets of movable blocks 10. One side of the backing plate 11 is in close contact with the air inlet head 4.

[0026] During operation, when installing the air intake head 4, it is necessary to insert the air intake head 4 into the air intake port 2. During this process, one side of the air intake head 4 will abut against the abutment plate 11 and move it into the air intake port 2. At this time, the moving block 10 also moves on the long rod 9 towards one end of the long rod 9 and compresses the spring 12. When the locking block 7 on the outside of the air intake head 4 rotates to the middle of the L-shaped groove 6, the air intake head 4 is released. The compressed spring 12 pushes out the abutment plate 11 and pushes the locking block 7 into the L-shaped groove 6. At this time, due to the design of the L-shaped groove 6, the locking block 7 will move out of the L-shaped groove 6, that is, the air intake head 4 cannot be pulled out of the air intake port 2.

[0027] Furthermore, such as Figure 4 As shown, a spring 12 is sleeved on the outside of the long rod 9, and the two ends of the spring 12 are fixedly connected to the moving block 10 and one end of the moving groove 8.

[0028] When in operation, when the spring 12 is not subjected to external force, it will push the moving block 10 and the abutment 11 against the end of the long rod 9 near the outside of the air inlet 2. Therefore, when the locking block 7 enters the middle of the L-shaped groove 6, the spring 12 is compressed and will push the locking block 7 outward and into the L-shaped groove 6 to fix the locking block 7.

[0029] Furthermore, such as Figure 4 As shown, a sealing block 13 is provided inside the through groove 5, and the sealing block 13 is fixedly connected to the outside of the abutment plate 11.

[0030] During operation, when the connector 1 and the air inlet 4 are connected and installed, the through groove 5 and the L-shaped groove 6 will allow the air inlet 2 to communicate with the outside. In order to prevent gas leakage, the sealing block 13 is set in the through groove 5. Therefore, when the connector 1 and the air inlet 4 are connected and installed, the sealing block 13 blocks the communication between the air inlet 2 and the outside.

[0031] Furthermore, such as Figure 3 and Figure 4 As shown, a sealing ring 14 is fixedly connected to the side of the back plate 11 near the air inlet head 4, and a sealing ring 14 is fixedly connected to the side of the connection port 3.

[0032] During operation, the installation of the sealing ring 14 ensures that no gas leakage occurs when gas flows through the air inlet 2 and the connection port 3.

[0033] Working principle: The connector 1's connector port 3 is threadedly connected to the corresponding device requiring gas entry. After the connector 1 is installed, the locking blocks 7 on both sides of the gas inlet head 4 are aligned with the through groove 5 opened inside the gas inlet 2 at one end of the connector 1, and the gas inlet head 4 is inserted into the gas inlet 2. At this time, the locking blocks 7 enter the through groove 5. When the locking blocks 7 enter the through groove 5, one end of the gas inlet head 4 is pressed tightly against the abutment plate 11 and pushed into the gas inlet 2. The sealing block 13 entering the through groove 5 does not affect the locking blocks 7 entering the L-shaped groove 6. At this time, the spring 12 is compressed, and the correct and appropriate rotation... Rotate the air intake head 4 to allow the locking block 7 to enter the L-shaped groove 6. Release the compressed spring 12 of the air intake head 4 to push the abutment 11 outward. At this time, the locking block 7 enters the interior of the L-shaped groove 6. The tendency of the abutment 11 to continue pushing outward is blocked, so the air intake head 4 cannot be pulled out further and reaches a fixed state. If it is necessary to disassemble the air intake head 4, simply push the air intake head 4 into the air intake port 2 and rotate the air intake head 4 in the opposite direction to allow the locking block 7 to enter the L-shaped groove 6. Then release the compressed spring 12 of the air intake head 4 to pop the abutment 11 outward and push the air intake head 4 out of the air intake port 2 to complete the disassembly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
