[0022] In order to make the content of the utility model more clearly understood, the utility model is further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0023] Embodiment 1:

[0024] like Figure 1-7 As shown, a direct pneumatic tube connector includes:

[0025] A main body part 1, the main body part 1 has a first end 2 and a second end 3, a first channel 11 is provided inside the main body part 1, and the channel is connected with the first end 2 and the second end 3;

[0026] The second end 3 is provided with a second installation cavity, a threaded column 31 is provided in the second installation cavity, the threaded column 31 is provided with a second channel 311, and the second channel 311 is connected to the first channel 11;

[0027] The rotary switch comprises a base 41, a knob 42 and a rotary valve 43. The base 41 is fixedly mounted on the main body 1, the rotary valve 43 is mounted in the first channel 11, the knob 42 is mounted on the base 41, and the knob 42 is connected to the rotary valve 43;

[0028] A clamp 32 is also provided in the second installation cavity, and the clamp 32 is suitable for fixing the interface between the threaded column 31 and the pneumatic tube;

[0029] An L-shaped structure 421 is also installed on the knob 42, and a limit block 411 is also provided on the base 41. The limit block 411 and the L-shaped structure 421 cooperate with each other to limit the rotation angle of the knob 42. The two arms of the L-shaped structure 421 are of moderate length and can reliably contact the limit block 411 to play a limiting role, so that it can rotate back and forth between the limit blocks 411 to achieve angle control of the knob 42.

[0030] In this embodiment, the first end 2 is provided with a connection method such as a thread or a buckle, which is convenient for quick connection with a pneumatic pipeline or other equipment. The second installation cavity has a certain depth, and the diameter of the threaded column 31 is smaller than the port diameter of the second end 3;

[0031] The knob 42 is designed with a humanized handle shape, which is convenient for users to rotate and operate. The knob 42 is connected to the rotary valve 43 through a connecting rod to achieve synchronous action of the rotary switch.

[0032] In this embodiment, the pneumatic tube is screwed into the threaded column 31 of the second installation cavity by threading, and then the clamp 32 is slid along the pneumatic tube toward the interface and tightened appropriately to clamp the interface between the pneumatic tube and the threaded column 31 to prevent leakage or loosening, ensuring that the interface between the pneumatic tube and the threaded column is clamped to prevent leakage or loosening.

[0033] Specifically, a filter screen is provided inside the first channel 11 .

[0034] Specifically, the rotary valve 43 includes a sealing ring, which is disposed at the interface between the rotary valve 43 and the first channel 11 .

[0035] Specifically, the knob 42 is provided with anti-skid patterns. The anti-skid patterns are designed with raised dot-shaped or line-shaped textures to increase the roughness of the knob 42 surface.

[0036] In the present invention, a section of pneumatic tube is connected to the threaded column 31 of the second installation cavity by threading, and the interface is further fixed by a clamp 32. The other end is connected to another section of pneumatic tube or other structure. By rotating the knob 42, the rotary valve 43 can be driven to open or close in the first channel 11, so as to accurately control the on and off of the gas; to prevent impurities from entering the pipeline system, a filter screen is set inside the first channel, which can effectively intercept particulate impurities in the pipeline and protect downstream equipment from contamination; a sealing ring is also provided between the rotary valve 43 and the first channel 11, and the sealing ring is fixed by pre-pressing assembly or slotting, which can form a reliable seal and effectively prevent gas leakage.

[0037] Embodiment 2:

[0038] The direct pneumatic tube connector of this embodiment is basically the same as that of the first embodiment, except that: a fixing sleeve is provided on the second end 3, and the clamp 32 is a conical clamp. The pneumatic tube is connected to the threaded column 31 of the second installation cavity by threading. At this time, the clamp 32 is sleeved at the connection between the pneumatic tube and the threaded column 31. Then, the fixing sleeve is slid along the tube body from the far end of the second end 3 until it fits tightly with the conical clamp 32. The function of the fixing sleeve is to squeeze and lock the conical clamp 32, thereby firmly fixing the connection between the pneumatic tube and the threaded column 31. This design can provide more reliable sealing and fixing force, and effectively prevent leakage or loosening at the joint. At the same time, this connection method is also easy to disassemble and maintain.

[0039] The specific embodiments described above further illustrate the technical problems, technical solutions and beneficial effects solved by the present invention. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
