Description

一种多段伸缩套管装置 A multi-section telescoping tube means

技术领域 FIELD

[0001]本发明涉及机械连接领域,具体地,涉及一种多段伸缩套管装置。 [0001] The present invention relates to the field of mechanical connection, in particular, it relates to a multi-section telescoping tube means.

背景技术 Background technique

[0002] 多段伸缩套管用于很多种需要多节伸长和缩短的场合,比如多节伸缩警棍、多节液压或气压升起装置等。 [0002] multistage telescoping tube need for a wide variety of multi-section extensible and contractible occasions, such as multi-section telescopic batons, multi-section like a hydraulic or pneumatic lifting means. 在许多情形下需要多节套管伸长后锁定,以提供相应的功能。 After the required multi-section elongate locking sleeve in many cases, to provide the corresponding functions. 比如三节警棍需要三节套管完全展开后实现三节固定以实现可用于打击的功能。 For example, three batons need after three sleeves fully expanded achieve three fixed function can be used to achieve the strike. 目前多节套管的锁紧方法常见的有以下几种:贯穿锁簧式,有一弹性锁簧锁定时锁簧贯穿两根套管的外壁,如在雨伞把中的应用;锥度套管式,内管和外管有一定的锥度,伸长时内外管依靠外管内壁和内管外壁之间两个锥面的摩擦形成锁紧;内部卡扣式,即在两管展开后相邻的一侧内壁分别开槽,然后将卡扣分别卡入槽内,实现两管的相对固定。 The method of the current multi-section lock sleeve common are the following: the through-type lock spring, a resilient latch spring when the locking spring locking sleeve through an outer wall of two, as in the application umbrella; tapered telescopic, inner and outer tubes have a taper, the inner and outer tubes depend on the friction between the two tapered surfaces of the inner wall of the outer tube and the inner tube when the external wall forming an elongated locking; internal snap, i.e. two adjacent expanded after a side inner wall slot, respectively, and then snap the card into the slot, respectively, to achieve the two relatively fixed. 在一些特殊场合,比如多节伸缩警棍中,为了保持两管的机械强度,不能采用贯穿开孔的方式锁紧;为了便于锁紧和收回,锥度锁紧的方法也不太适合。 In some special occasions, such as multi-section telescopic baton in order to maintain the mechanical strength of the two, by way of the through hole can not lock; in order to facilitate the locking and retracted, the method is not very suitable locking taper.

[0003] 目前现有的伸缩警棍多为锥度锁警棍,可伸缩的棍体间凭借金属件的摩擦力而连接在一起,正常情况下,在垂直方向由棍头向棍尾敲击可以回收。 [0003] Normally, in the vertical direction of the rapping can be recovered currently available telescopic batons batons mostly taper lock, friction with the metal member are connected together between the telescopic stick body, from the club head to the end of the stick. 打开时,用手腕的力量,或者用前臂带动手挥出,棍子在惯性作用下会顺手挥动的方向运动,并且在节链接处靠锥面摩擦阻力而停止和锁紧。 When opened, with the strength of the wrist, forearm or hand hit the drive, stick in the inertia will easily waving direction, and stopped by friction cone section and locked at the link. 但是这种锁紧方法存在诸多缺陷,首先打开时,甩的力量不易过大,一时用力,可能导致让棍子锁定过紧,影响回收。 However, there are many defects such locking method, when first opened, the rejection of excessive force is not easy, sometimes hard, so that could lead to a stick locked tight, influence recovery. 其次,在使用过程中碰到人身或硬物时,容易出现棍体间的自动回缩,影响使用效果。 Next, when the person hit a hard object or during use, between the self-retracting stick body prone to affect the results. 因此内部卡扣锁紧方式为当代高级警棍所米用。 Therefore, internal locking snap the way for contemporary advanced meters with batons.
