Description of the invention: [Technical field to which the invention pertains] The present invention relates to a foot column, and more particularly to a bicycle stud that is interlocked with one side of a pivotal seat to form a mutual lock. 6 positions, so that the foot column does not cause slack.疋[Prior Art] According to the 'traditional bicycle's foot column, it is mainly pivoted in a towing seat, and the spring in the pivoting seat abuts against the pressure block and has a downward elastic tension' The spring and the pressure block in the pivoting seat elastically resist the engine, and the use of the spring is easy to lose the elastic tension due to the elastic fatigue, so that the kick is easy to slack and fall after kicking, so it is necessary to improve. The present inventor is devoid of the lack of the bicycle legs of the above-mentioned bicycles, so the experience of many years of production and sales of the related products of the car, and the related problems of the 'thinking improvement method, after the multi-nucleus and test Finally, a self-locking foot column was invented. [Summary of the Invention] The main purpose of the illusion s = month is to provide a self-locking foot column, which is specially designed to provide the bicycle foot on the kick post and the pivot joint. Furthermore, in another aspect of the present invention, when the kick is in a support state, the foot column and the pivot joint also have a lock position; and the bicycle is prevented from being touched and blown due to the looseness of the foot column. [Embodiment] FIG. 1 - The present invention provides a self-locking cutting column. The rail is referred to the structural design shown in FIG. 5: 1288721, which includes: a pivoting seat 10, which is fixed at one end and fixed to the bicycle frame. The bottom end of the pivoting seat 10 has a pocket 1 1 for receiving a spring 30 and a pressing block 40. The groove 1 1 extends from the front and rear sides to a suitable shape of the lug 1 2 , the lug A buckle groove 13 is formed on the rear side of the 12, and a concave-shaped class surface 14 is formed in the front lug 12, and a shaft hole 15 is formed in the front and rear of the cavity 1 1 of the pivoting seat 10 The leg post 20 is inserted and rearwardly pivoted; a leg post 20 is a pivotal end 2 2 having a pivot hole 2 1 and is pivotally connected to the pivot socket 10, and the pivot end 2 2 A notch rim 2 3 is formed on one side, and the groove 1 1 of the front end of the pivoting seat 10 is directly deducted. The front end of the leg 2 0 pivoting end 2 2 is fixed on the front end pivot hole 2 1 and recessed a self-locking device 50; a self-locking device 50, which is disposed between the pivoting seat 10 and the pivoting end 22 of the leg 20, and is elastically biased by a spring 5 1 0 and a top bead 5 1 1 a piece 5 1 and a buckle φ which is protruded from the outer side of the pivotal end of the foot column 2 0 5 2, wherein the elastic resisting member 5 1 is received in a recessed hole 2 5 under the pivot hole 2 1 of the back end of the leg 20; the structure and position of the components of the present invention are An overview of the interconnections; then, the actions of the various components of the creation and the expected effects achieved are as follows: Please refer to the fifth and sixth figures, when the foot of the present invention is not kicked When the pivoting end 2 2 - the notch card edge 2 3 of the pivoting seat 10 is just buckled at the front edge of the receiving slot 11 of the pivoting seat 10, at this time, since the pivoting seat 10 receives the groove 1 1 before the lug 1 2 Forming a concave-shaped class surface 14 such that the foot of the 6 1288721 is restrained by the convex surface 140 of the class face 14, and the elastic resisting member 51 of the back end of the leg 20 is forced to be pressed in the concave hole 2 5 inside. Continued to refer to the seventh figure to the ninth figure, and when the foot column 20 is kicked, the pivoted seat 1 is the groove 1 1 front lug 1 2 the convex surface of the class surface 1 4 〇 The foot column 2 夹 处 〇 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 2 When the level of the class is 1 4, since the concave-shaped class surface 1 4 widens the cavity 1 1 , the foot column 2 can be pivotally connected by the back end of the elastic member 5 1 The end 2 2 pushes the top outward, and at the same time, the buckle block 52 located on the outer side of the pivotal end of the leg post 2 is buckled into the recessed groove 13 of the rear side of the pivoting seat 1 〇 lug 1 2 , The foot column 2 〇 and the pivot socket 10 form a mutual locking position, so that the foot column 2 does not cause a self-locking effect of slack and slip. It is necessary to specifically note that when the user wants to kick back When the foot is 2 〇, since the ankles 2 are all about 30° with the frame, the φ is still stretched out after the kick, so the user has to kick back the foot 2 At the time of the squatting, H is about 45. The direction is downward, and the force is applied downwards. According to the invention, as long as the angle of the foot of the conventional method is applied, the back end of the ankle 2 of the front lug 1 2 of the splicing seat 1 can be pressed against the elastic resist 5 i, and then the buckle 5 2 It can be moved downwards from the limit of the buckle groove 13. In addition, the pivot socket 1 has a lug 1 2 extending from the front and rear sides of the cavity 1 and a lower side of the front lug. The upper recess is further formed to form a second buckle groove 16' so that the p-pillar 20 is supported by the lower kick, and has a self-locking effect, which prevents the bicycle from being touched or the wind is blown due to the looseness of the foot column. 1288721 (as shown in the tenth and eleventh figures). Advantageously, the structural principle of the present invention can also be applied to the pivot joint of the rear leg (as shown in Fig. 12). As described above, the self-locking foot column of the present invention has great industrial value, and has not been seen in various books or public use. It is in line with the requirements of the invention patent application, and the 钧局明鉴, as soon as the patent is granted, is the pray. The description is only one of the preferred embodiments of the present invention, and therefore, the application specification and application are applied. The equivalent structural changes of the present invention are included in the scope of the present patent.
