Embodiment Construction
[0014] Below in conjunction with accompanying drawing and embodiment the present invention will be further described
[0015] An auxiliary butt joint structure for connecting soft and hard small outer diameter pipes (as attached figure 1 As shown), its characteristics are that the two ends of the auxiliary butt joint 1 are respectively arranged: a hard pipe end 2 with a small outer diameter and a hose end 3 with a large outer diameter, and the outside of the two pipe ends is a bell mouth;
[0016] Wherein, the inner end side of the hose end 3 is a bell mouth.
[0017] Examples (as attached figure 2 As shown), inside the auxiliary butt joint 1, a gap Δ of 3 mm is set between the hard pipe end 2 and the hose end 3, and its function is to accommodate the expanded part of the hose after butt joint.
[0018] The outer diameter of the hard pipe end 2 is 0.8-3.2mm; the outer diameter of the hose end 3 is 2.6-6.5mm; the bell mouth is 60-90°.
[0019] During the assembly process, t...

The invention relates to an auxiliary butt joint connected to a soft and hard small outer diameter pipe and relates to the technical field of soft and hard pipe connection. The auxiliary butt joint ischaracterized in that a small outer diameter hard pipe end and a large outer diameter soft pipe end are separately arranged at two ends of the auxiliary butt joint, and the two pipe ends are horn-shaped externally, wherein the inner end side of the soft pipe end is a horn mouth. A gap delta is formed between the hard pipe end and the soft pipe end in the auxiliary butt joint. In an assembling process, the metal (hard) pipe moves forward continuously to meet the head of the soft pipe. As the back side of the soft pipe is limited by an auxiliary connecting head, the soft pipe only can be expanded (flared) under the pressure of the metal (hard) pipe to enclasp the head of the metal (hard) pipe. In conclusion, the auxiliary butt joint connected to the soft and hard small outer diameter pipe is simple in structure, convenient to process and easy to operate, can finish butt joint by a simply unidirectional feeding action, and is in particular suitable for the technical field of soft and hard pipe connection under conditions of compact structure and narrow external space.
Description
technical field [0001] The invention relates to the technical field of connecting soft and hard pipes, in particular to an auxiliary butt joint for connecting soft and hard pipes with small outer diameters. Background technique [0002] Under vacuum conditions, due to the effect of pressure difference, there is generally no need for auxiliary reinforcement after the connection of soft and hard pipes, but when the inner diameter of the hose is slightly smaller than the outer diameter of the hard pipe, when the two are connected, the hose and the hard pipe The end of the machine is at a certain angle, and a part of it is put in first, and then the rest is sent in, which usually requires a certain amount of space for operation. However, in small instruments, due to the narrow space, it cannot accommodate the operation space of one hand. Contents of the invention [0003] The purpose of the present invention is to overcome the defects and deficiencies in the prior art, and pr...
