Definitions

  • the present invention relates to an electric wire built-in telescopic pipe, and more specifically, to a telescopic pipe in which the inner and outer pipes move relative to each other, the inner pipe has a double-layered structure of the main body and the sub-tube, and a cleaner through the upper sub-tube It relates to an electric wire built-in telescopic pipe having a wire extending from the main body to a suction member that sucks dust and the like.
  • the support tube is coupled to the rear end, and includes a sealing material that seals a gap generated between the inner circumferential surface of the inner tube, and it is preferable that the front end is located in front of the front end of the exterior.
  • the inner pipe is made of a double-layer pipe structure, and the electric wire passing through the inner pipe always passes through the sub-pipe formed inside the inner pipe regardless of the expansion and contraction of the inner and outer pipes, thus simplifying the shape of the inner and outer pipes. It is possible to improve the aesthetics and motor function of the appearance of the inner and outer tube, and furthermore, it is possible to more efficiently maintain and maintain the new tube by reducing breakdown or damage.
  • FIG. 6 is an exploded perspective view showing an inner tube portion of FIG. 2 as a center;
  • FIG. 7 is a cross-sectional view taken along line AA in FIG. 3.
  • the exterior 3 and the inner tube 5 are in the folded position, and the exterior 3 is no longer in the folded position. It is preferable that it is designed to achieve a rear dead point that cannot be retracted back, and the fastener 75 is caught in the pitch groove 20 at the end in this position, so that the inner tube 5 is not operated unless the lock bundle 7 is operated. Relative movement is blocked.

Abstract

La présente invention concerne un tuyau télescopique avec fil intégré, comprenant un tuyau externe ; un tuyau interne inséré de façon mobile dans le tuyau externe, et dans lequel une pluralité de rainures de pas sont formées dans la direction longitudinale sur la surface circonférentielle externe de celui-ci ; et un ensemble de verrouillage installé pour pénétrer dans la surface de paroi du tuyau externe et qui, lorsqu'ils sont coincés au niveau des rainures de pas, verrouille le tuyau externe et le tuyau interne pour être fixés l'un à l'autre, le tuyau interne comprenant un corps de tuyau principal qui forme un passage d'air dans la direction longitudinale ; et un corps de sous-tuyau séparé du corps de tuyau principal par une plaque de séparation et forme un passage de fil dans la direction longitudinale. Par conséquent, étant donné qu'un fil s'étendant du corps principal d'un dispositif de nettoyage à un élément d'aspiration passe à travers le tuyau interne ayant une structure de tuyau à deux couches, indépendamment de l'état télescopique des tuyaux interne et externe, les formes des tuyaux interne et externe avec le fil intégré peuvent être simplifiées. Ainsi, l'esthétique de l'apparence des tuyaux interne et externe et de la fonctionnalité de mouvement peut être améliorée, et en outre, une défaillance ou un endommagement est réduit de telle sorte que la maintenance du tuyau télescopique peut être gérée de manière plus efficace.
