Detailed description of the invention
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of fast assembling disassembling structure of balance car turning-bar, the speeder wrench device comprising shaft seat 2, steering yoke 1 and be positioned on shaft seat 2.Steering yoke 1 inserts in shaft seat 2, is provided with guide ledges 22 in shaft seat 2, and the end of steering yoke 1 is provided with the recess coordinated with guide ledges 22.Speeder wrench device is used for steering yoke 1 and shaft seat 2 fast assembling-disassembling.The micro-adjusting mechanism 5 that speeder wrench device comprises cam spanner 3, straight pin 4, compaction plug 6 and is fixed on shaft seat 2.The sidewall of shaft seat 2 is provided with shoulder hole 21, and compaction plug 6 is mated with shoulder hole 21 and is arranged in shoulder hole 21, compaction plug 6 is arranged with rubber ring 7.One end of cam spanner 3 is provided with cam 31, and cam 31 is butted in compaction plug 6.Straight pin 4 is fixed on micro-adjusting mechanism 5, and cam 31 to be fixed on straight pin 4 and to rotate around straight pin 4.Moving cam spanner 3 makes cam 31 rotate around straight pin 4, protuberance and the mild position of cam 31 are alternately butted in compaction plug 6, when the protuberance of cam 31 is butted in compaction plug 6, compaction plug 6 compaction direction bar 1, rubber ring 7 compacted plug 6 crimp simultaneously, steering yoke 1 is fixed with shaft seat 2, when the mild position of cam 31 is butted in compaction plug 6, the external force of compaction plug 6 is removed, and rubber ring 7 resiles, thus promoting compaction plug 6 away from steering yoke 1, steering yoke 1 can be extracted out from shaft seat 2.
Micro-adjusting mechanism 5 comprises frid 51 and pressing plate 52, frid 51 is fixed on shaft seat 2, frid 51 is provided with horizontal strip slot 511, straight pin 4 is arranged in strip slot 511, pressing plate 52 is pressed on straight pin 4, be provided with gap between the bottom land of straight pin 4 and strip slot 511, the gap between the bottom land of straight pin 4 and strip slot 511 is adjusted by pressing plate 52.Hinged between one end of pressing plate 52 and frid 51, be provided with distance adjustment part between the other end of pressing plate 52 and frid 51.Distance adjustment part is screw 53, and pressing plate 52 is provided with aperture, and frid 51 is provided with screw, and screw 53 is twisted in screw through aperture.Frid 51 is provided with convexly buckles 512, and cam spanner 3 is provided with the recessed button 32 coordinated with convex button 512.
The course of work of the present embodiment: due to Reusability, occur between cam 31 and compaction plug 6 repeatedly rubbing, thus cam 31 and compaction plug 6 are worn and torn, now adjust the distance between pressing plate 52 and frid 51 by screw 53, thus straight pin 4 is pressed into the side of the bottom land near strip slot 511, thus cam 31 is adjusted more near steering yoke 1, thus compensate the wearing and tearing of cam 31 and compaction plug 6, the protuberance of cam 31 foot being pressed on steering yoke 1 in compaction plug 6 being held out against, making steering yoke 1 more reliable with fixing of shaft seat 2.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, and under the prerequisite not departing from inventive concept of the present utility model, any apparent replacement is all within protection domain of the present utility model.
