DETAILED DESCRIPTION

[0026] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] See also Figure 1-Figure 8 As shown, an anti-blowout pneumatic connector includes a connector 1, an adjusting rod 2 for controlling the flow in the connector 1, and a connecting clamping assembly 3 for quickly installing and preventing the pipe and the connector 1 from falling off. The connecting clamping assembly 3 includes a buckle 31 and an external threaded sleeve 32 for bending the buckle 31. The buckle 31 includes a clamping block 33. The pneumatic connector 1 also includes a fixed adjusting assembly 4 for locking the adjusting rod 2. The buckle 31 is made of a flexible memory material and is in the shape of a half fan.

[0028] When quickly installing the pipeline and the connector 1, first insert the pipeline into the connector 1, and then rotate the external threaded sleeve 32. When the external threaded sleeve 32 rotates, the external threaded sleeve 32 can contact the pressure block 35. First, rotate the external threaded sleeve 32 until the external threaded sleeve 32 rotates and moves between the connector 1 and the pipeline. Then, when the external threaded sleeve 32 is rotated, the buckle 31 and the block 33 are squeezed and bent, and bent toward the outer wall of the pipeline, so that the buckle 31 and the block 33 are pressed against the pipeline, thereby completing the quick connection between the pipeline and the connector 1, which can prevent the connector 1 from being disconnected from the pipeline due to large airflow during connection.

[0029] See also Figure 1 and Figure 7 As shown, an anti-blowout pneumatic joint, the clamping assembly also includes a silicone sealing ring 34; the silicone sealing ring 34 is arranged on the outside of the pneumatic joint 1, and a plurality of silicone sealing rings 34 are arranged equidistantly in a segmented circular shape.

[0030] When the external threaded sleeve 32 rotates and moves, the silicone sealing ring 34 is bent and compressed, and deformed during the bending process to fit the outer wall of the pipe, so as to prevent gas leakage at the connection between the pipe and the joint 1 and improve the sealing between the pipe and the joint 1.

[0031] See also Figure 1 and Figure 7 As shown, an anti-blowout pneumatic joint, the clamping assembly also includes a pressure block 35; the pressure block 35 is arranged at the upper end of the buckle 31, and the pressure block 35 is made of a flexible reset material.

[0032] When the external threaded sleeve 32 rotates, the pressure block 35 first contacts the external threaded sleeve 32 and is bent inside the joint 1 by the rotational pressure of the external threaded sleeve 32, thereby causing the buckle 31 and the clamping block 33 to perform the same action. A plurality of pressure blocks 35 are provided to make the force more uniform.

[0033] The fixed adjustment component 4 includes a gear ring 41 and a pressing block 42 ; the gear ring 41 is arranged outside the adjustment rod 2 , and the gear ring 41 is coaxially fixed with the adjustment rod 2 ; the pressing block 42 is horizontally slidably arranged on the joint 1 .

[0034] When the adjusting rod rotates, the gear ring 41 is driven to rotate synchronously, and the clamping block 42 can contact the rotating gear ring 41 and engage the gear ring 41 to limit the rotation of the gear ring 41 and the adjusting rod 2, so as to fix the adjusting rod 2 after rotation, and then control the air flow in the joint to prevent the adjusting rod 2 from self-rotating.

[0035] See also Figure 1 and Figure 7 As shown, an anti-blowout type pneumatic joint, the fixed adjustment component 4 also includes a mounting block 43 and a positioning rod 44; the mounting block 43 is arranged on the joint 1, the mounting block 43 is a square hollow shape, and an avoidance groove for the tightening block 42 to pass through is opened on the mounting block 43; the positioning rod 44 is arranged in the mounting block 43; the positioning rod 44 is slidably matched with the tightening block 42.

[0036] The pressing block 42 can slide smoothly under the restriction of the positioning rod 44. The positioning rod 44 is cylindrical in shape and can drive the pressing block 42 to slide horizontally and contact the gear ring 41. The shape of the pressing block 42 matches the shape of the gear ring 41.

[0037] See also Figure 1 and Figure 7 As shown, an anti-blowout type pneumatic joint includes a fixed adjustment component 4 and a reset spring 45; the reset spring 45 is installed on the outside of the guide rod 44, and its two ends are respectively fixed to the guide rod 44 and the mounting block 43.

[0038] The setting of the return spring 45 can drive the pressing block 42 to always contact the ring gear 41 . In the initial state, the pressing block 42 is engaged with the ring gear 41 to fix the ring gear 41 .

[0039] See also Figure 1 and Figure 7As shown, an anti-blowout pneumatic joint includes a fixed adjustment component 4 and an L-shaped block 46; the L-shaped block 46 is installed on the upper end of the tightening block 42, and the upper end of the L-shaped block 46 is horizontally arranged with the top end of the adjustment rod 2.

[0040] When the adjusting rod 2 is rotated, the L-shaped block 46 is first pulled outward, thereby causing the abutting block 42 fixed below the L-shaped block 46 to move synchronously. At this time, the abutting block 42 moving outward loses the engagement with the gear ring 41.

[0041] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
