Problems solved by technology

[0002] At present, the adjustment and fixing of the saddle tube (also known as seat post) of ordinary bicycles or folding bicycles and the stand tube (also called seat tube) on the frame is to relax or contract the stand tube by bolts or cam mechanisms (quick clips). The inner diameter of the tube can achieve the purpose of loosening or holding the saddle tube tightly. Some of these existing technologies need special tools to adjust, and some do not need special tools to adjust, but it is very laborious, and the reliability is not high. The phenomenon of sinking and turning, the main defect is that it cannot realize the function of automatic retraction and expansion when applied to folding bicycles, let alone the requirement of the saddle height adjustment position recovery function

Embodiment 1

[0053] as attached figure 1 As shown, the rotary engagement mechanism is a rotary engagement mechanism of an incomplete circular thread, and the rotary engagement mechanism of the incomplete circular thread includes an incomplete circular external thread and an incomplete circular internal thread meshing with it, and the incomplete circular thread The circular external thread and the incomplete circular internal thread are evenly and continuously distributed in the axial direction, the incomplete circular external thread is distributed on the circular arc surface in one segment, and the one-stage incomplete circular The internal thread 12 and the one-piece non-complete circular external thread 11 engaging with it have corresponding thread engagement features.

[0054] The one-stage incomplete circular external thread 11 and the one-stage incomplete circular internal thread 12 meshed with it have a thread arc of 175°, and the depth of the non-thread separating groove on the inc...

Embodiment 2

[0056] as attached figure 2 As shown, the rotary engagement mechanism is a rotary engagement mechanism of an incomplete circular thread, and the rotary engagement mechanism of the incomplete circular thread includes an incomplete circular external thread and an incomplete circular internal thread meshing with it, and the incomplete circular thread The circular external thread and the incomplete circular internal thread are evenly and continuously distributed in the axial direction. The incomplete circular external thread is divided into two sections and evenly distributed on the circular arc surface. The two-stage incomplete circular The arc of each section of thread on the external thread 22 is not greater than the arc of each section of non-threaded separation groove, the arc of each section of thread on the two-stage non-complete circular external thread 22 is 88°, and the non-threaded separation The depth of the groove is greater than the tooth height of the thread, and t...

Embodiment 3

[0058] as attached image 3 As shown, the rotary engagement mechanism is a rotary engagement mechanism of an incomplete circular thread, and the rotary engagement mechanism of an incomplete circular thread includes an incomplete circular external thread and an incomplete circular internal thread meshing with it, and the incomplete circular external thread The non-complete circular internal thread is evenly and continuously distributed in the axial direction, and the non-complete circular external thread is divided into three sections and evenly distributed on the circular arc surface. The three-stage non-complete circular external thread 32 The radian of each segment of the thread is not greater than the radian of each segment of the non-threaded separation groove, the arc of each segment of the thread on the three-segment incomplete circular external thread 32 is 58°, and the depth of the non-threaded separation groove is greater than that of the thread The three-stage incomp...

Abstract

The invention discloses a telescopic positioning device and application thereof and belongs to the technical field of telescopic connection. Engaging positioning or separation telescopic type connection is achieved through convex and concave engaging mechanisms which are evenly and continuously distributed; each convex and concave engaging mechanism comprises a convex tooth component and a groove component engaged with or disengaged from the convex tooth component; the engaging portion of each convex tooth component is provided with at least one partition groove in the cross section perpendicular to the relative displacement direction so that the two parts can stretch out and draw back and can be positioned; the convex and concave engaging mechanisms comprise the rotating engaging mechanism of non-complete round threads, the wedge expansion engaging mechanism and the rotating engaging mechanism of a non-circular cross section cam shaft; and the rotating engaging mechanism of the non-complete round threads can be applied to functional mechanisms of lifting and folding position restoration of bike seats or bike handlebars. The telescopic positioning device achieves the fast telescopic adjusting, locking and positioning through the threads or a pawl mechanism. Compared with a similar hydraulic or pneumatic mechanism, the telescopic positioning device is easy to manufacture, low in weight and reliable in performance, and cost is substantially reduced.

Description

technical field [0001] The invention belongs to the technical field of telescopic connection, in particular relates to a telescopic positioning device, and also relates to its application. Background technique [0002] At present, the adjustment and fixing of the saddle tube (also known as seat post) of ordinary bicycles or folding bicycles and the stand tube (also called seat tube) on the frame is to relax or contract the stand tube by bolts or cam mechanisms (quick clips). The inner diameter of the tube can achieve the purpose of loosening or holding the saddle tube tightly. Some of these existing technologies need special tools to adjust, and some do not need special tools to adjust, but it is very laborious, and the reliability is not high. The main defect of sinking and turning phenomenon is that it cannot realize the function of automatic shrinking and unfolding when applied to a folding bicycle, let alone the requirement of the saddle height adjustment position recove...
