Abstract
The utility model relates to an elbow connection for a cotton suction flute pipe. A pipe body comprises a straight pipe part and an elbow pipe part, wherein the straight pipe part and the elbow pipe part are two sections of independent pipe bodies which are movably connected with each other; and an annular projection for enabling the bore diameter of the pipe body to be reduced is formed in the pipe body of the straight pipe part. The straight pipe part of the elbow connection can replace a straight connection in use; and the annular projection of the variable diameter part is formed in the pipe body of the straight pipe part, so that the elbow connection is convenient to process and can meet the requirements for different mounting positions.
Description
Technical field
The utility model relates to a kind of fine spining machine suction tube device, specifically a kind of suction tube joint.
Background technology
The suction tube that uses on the fine spining machine is used for drawing a kind of device of spinning broken end and flyings, short flannel, cotton dirt.The disclosed a kind of so just device of Chinese patent CN201068495Y, suction tube is connected on the air main by joint (being total suction inlet) and pipeline, negative-pressure air fan is bled to suction tube by air main, connecting pipe and joint, makes to form negative pressure in the suction tube.Difference according to the suction tube kind, this joint has straight joint and two kinds of structures of bent sub usually, wherein bent sub is the suction tube that is used for 10 ° of types, straight joint is the suction tube that is used for 35 ° of types, and cotton spinning processing enterprise is owing to the different reason of selecting of suction tube, need to use two kinds of joints, but because both can not replace, producing to enterprise makes troubles.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, provides a kind of simple in structure, can substitute the suction tube bent sub of straight joint.
For achieving the above object, the utility model has adopted following technical scheme: body comprises straight-tube portion and bent tube section, and straight-tube portion and bent tube section are two sections bodys independently, and two sections bodys flexibly connect.Wherein the body of straight-tube portion can substitute the straight joint use.
For two sections bodys are connected closely, the outer wall of two sections built-in links of body is provided with annular protrusion or annular groove, and the annular groove or the annular protrusion that cooperate with described annular protrusion or annular groove are arranged on the inwall of external link.Because body is a working of plastics, utilizes the elasticity of himself, by projection on the tube wall and groove fit, it is not only convenient but also firm to connect.
In order to improve the sealing property of two sections body junctions, on two sections external link inwalls of body the step that cooperates with built-in link end face is arranged, have inside annular groove on the step wall, the annular protrusion that cooperates with annular groove on the described step wall is arranged on the end face of built-in link.
Because suction tube installation site difference on air main, the suffered negative pressure of each suction tube is inequality, and is big near the negative pressure of negative-pressure air fan one end, little away from the negative pressure of negative-pressure air fan one end.For can the different suffered negative pressure of suction tube in balanced installation site, a preferred version of the present utility model be in the straight-tube portion body inwardly protruding to be arranged and annular protrusion that the body aperture is reduced.Because the internal diameter of annular protrusion can reduce the ventilation cross section of joint less than internal diameter of tube body, select the different straight tube body in annular protrusion aperture, can adapt to the needs of different installation sites.
As shown from the above technical solution, the utility model both can be used as bent sub, and its straight tube body can substitute straight joint and use, the annular protrusion of reduced diameter portion is arranged in the straight tube body, easy to process, and its pore size has multiple size, to adapt to the needs of different installation sites.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model bend pipe pipe structure schematic diagram;
Fig. 3 is the utility model straight tube pipe structure schematic diagram.
The specific embodiment
As shown in Figure 1, the bent tube section of the utility model body and straight-tube portion are two sections bodys 1,2 independently, and the link of straight tube body 2 is built-in link in this example, and the link of bend pipe body 1 is external link.
The structure of straight tube body 2 as shown in Figure 3, with the annular protrusion 21 that cooperates with annular groove 11 on step 12 walls is arranged on bend pipe body 1 link 22 end faces, the annular groove 23 that matches with the annular protrusion 14 on bend pipe body 1 step 12 right sides is arranged on the outer wall of link 22. Body 1 and 2 is working of plastics, utilizes the elasticity of himself, and two sections bodys 1 and 2 cooperate and sealed by annular protrusion on the tube wall 14 and annular groove 23; Simultaneously the annular protrusion 21 of body 2 end faces and body 1 step 12 interior annular grooves 11 cooperate and can play the better seal effect.The annular protrusions 24 that also have inwardly protrudings in the straight tube body 2 and the body aperture is reduced, and annular protrusion 24 pore sizes have multiple size, to adapt to the needs of different installation sites.Straight tube body 2 uses as straight joint, and two ends can be connected with air main with suction tube respectively.
