Description

Mandrel assembly of pipe collector Technical Field The utility model relates to the technical field of mandrels, in particular to a mandrel assembly of a pipe collector. Background The hose is very popular in daily production and life, has the advantages of stronger elasticity, softness and tensile property, and is bending-resistant, and is often used as a wire and cable protective tube, a liquid pipeline, a gas pipeline, a ventilation pipeline and the like. The hose is generally stored by adopting a hose storage device, and the mandrel assembly of the hose storage device at present is unreasonable in design, so that the hose storage effect is poor, and the existing mandrel assembly cannot generally perform mass transfer or has poor effect. Disclosure of utility model Aiming at the problems in the prior art, the utility model provides the mandrel assembly of the pipe collector, which can ensure that the pipe collector obtains a better hose collecting effect and has a better transmission effect. In order to achieve the above purpose, the present utility model provides the following technical solutions: a mandrel assembly of a pipe retractor, comprising: The mandrel comprises a first barrel and a second barrel, wherein the second barrel is rotatably sleeved on the first barrel, a plurality of cavities are formed in the second barrel, the second barrel is provided with a connecting end, a plurality of first through holes are formed in the connecting end at intervals, a plurality of second through holes are formed in the peripheral surface of the second barrel, and the plurality of first through holes are respectively communicated with the plurality of second through holes through the plurality of cavities; The sleeve is fixedly sleeved on the second cylinder body, a plurality of third through holes are formed in the peripheral surface of the sleeve, and the third through holes are matched with the second through holes. The mandrel assembly of the pipe collector is further provided with the plurality of first through holes at intervals on the side face of the connecting end, the plurality of second through holes are formed at equal intervals along the length direction of the second cylinder body, and the mandrel assembly is wound at equal intervals by taking the central shaft of the second cylinder body as an axis. The mandrel assembly of the pipe collector is further provided with the plurality of first through holes which are arranged at the connecting end and far away from one side surface of the second cylinder body, the plurality of first through holes are wound around the central shaft of the second cylinder body, and the plurality of second through holes are uniformly spaced along the length direction of the second cylinder body and simultaneously wound around the central shaft of the second cylinder body at equal intervals. The mandrel assembly of the pipe collector is further provided with a plurality of first threaded holes on the side surface of the sleeve, which is far away from the connecting end. The mandrel assembly of the pipe collector is further characterized in that a plurality of first threaded holes are wound at equal intervals by taking the central shaft of the sleeve as an axis. The mandrel assembly of the pipe collector is further provided with a plurality of second threaded holes, and the second threaded holes are formed in the edge of one side face away from the second cylinder body and penetrate through the connecting end.
