Abstract

The invention provides a convex-concave engaging type telescopic positioning device and belongs to the technical field of telescopic connection. Engaging positioning or separated telescopic connection is formed through convex-concave engaging mechanisms which are evenly and continuously distributed. The convex-concave engaging mechanisms comprise convex tooth components and groove components engaged with or separated from the convex tooth components. At least one separation groove is formed in the sections, perpendicular to the relative displacement direction, of engaging positions on the convex tooth components, and then the convex tooth components and the groove components can conduct telescopic motion and positioning. The convex-concave engaging mechanisms comprise rotary engaging mechanisms with incomplete round threads, wedge-shaped expansion engaging mechanisms and non-circular section camshaft rotary engaging mechanisms. According to the device, engaging and separation of incomplete outer threads and inner threads are achieved through rotation or radial displacement, relative motion and locking and positioning of the parts in the axial direction are achieved, and no tool needs to be used during use. The device is safe, practical, easy to manufacture, low in weight and reliable in performance, the rapid telescopic function and the accurate positioning function can be achieved, and cost is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of telescopic connection, in particular to an engaging type telescopic positioning device. 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. Sinking and turning phenomena. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings and provide a convex-concave engagement type telescopic positioning device, which adopts uniform and continuou...
