Title (EN) TELESCOPIC TUBE DEVICE AND VACUUM CLEANER HAVING SAME
(FR) DISPOSITIF DE TUBE TÉLESCOPIQUE ET ASPIRATEUR LE COMPRENANT
(ZH) 一种伸缩管装置及具有其的吸尘器
Abstract:
(EN) The present invention relates to a telescopic tube device, comprising a first tube, a second tube that is slidably connected relative to the first tube, and an operating unit; the first tube is sleeved within the second tube; the operating unit is arranged at a sleeving position between the first tube and the second tube; the operating unit comprises a first locking member, a second locking member and a limiting member; when the telescopic tube device is in a locking state, the limiting member is at an initial position, and the first locking member and the second locking member remain engaged; when the telescopic tube device is in at least one releasing state, the limiting member is offset from the initial position, and the first locking member and the second locking member are disengaged; the operating unit further comprises at least one elastic member; when the limiting member is in the initial position, the elastic member provides the limiting member with a pulling force so that the limiting member has a tendency to remain in the initial position.
(FR) La présente invention concerne un dispositif de tube télescopique, comprenant un premier tube, un second tube qui est relié de manière coulissante par rapport au premier tube, et une unité d'actionnement; le premier tube est emmanché dans le second tube; l'unité d'actionnement est disposée dans une position de manchonnage entre le premier tube et le second tube; l'unité d'actionnement comprend un premier élément de verrouillage, un second élément de verrouillage et un élément de limitation; lorsque le dispositif de tube télescopique est dans un état de verrouillage, l'élément de limitation est dans une position initiale, et le premier élément de verrouillage et le second élément de verrouillage restent en prise; lorsque le dispositif de tube télescopique est dans au moins un état de libération, l'élément de limitation est décalé par rapport à la position initiale, et le premier élément de verrouillage et le second élément de verrouillage sont séparés; l'unité d'actionnement comprend en outre au moins un élément élastique; lorsque l'élément de limitation est dans la position initiale, l'élément élastique fournit, à l'élément de limitation, une force de traction de telle sorte que l'élément de limitation a tendance à rester dans la position initiale.
(ZH) 本发明涉及一种伸缩管装置,包括第一管、与所述第一管相对滑动连接的第二管和操作单元;所述第一管套设在所述第二管内;所述操作单元设置在所述第一管与所述第二管的套接处;所述操作单元包括第一锁定件、第二锁定件和限位件;当所述伸缩管装置处于锁定状态时,所述限位件在初始位置,所述第一锁定件与所述第二锁定件之间保持卡合;当所述伸缩管装置处于至少一个释放状态时,所述限位件偏离初始位置,所述第一锁定件与所述第二锁定件之间解除卡合;所述操作单元还包括至少一弹性件;当所述限位件在所述初始位置时,所述弹性件给予所述限位件拉力,使所述限位件具有保持在所述初始位置的趋势。
