[Prior Art] Press, the bicycle seat cushion is mainly used to support the rider's body weight, so that the rider can easily step on the pedal and achieve basic comfort; since the bicycle seat cushion must bear the rider's cause The downward pressure generated by the weight and the upward impact force transmitted from the ground to the seat cushion by the wheel, so the seat cushion and the vehicle body must have a better locking strength. Generally, the seat cushion of a bicycle usually has a locking structure to lock and lock the seat bow at the bottom of the seat cushion and the seat tube of the bicycle. However, at present, the industry has added a locking structure for adjusting the work M382239 to each bow. Between the seat tube and the seat tube, it is designed to cater to all types of riders' comfort. The similar locking structure is mainly provided with a set of clips on both sides of the top end of the bicycle seat tube, and a bolt is inserted between the seat tube and the two sets of clips; each set of clips is composed of two clips. The body is attached to the body, and a long groove is provided on the bonding surface of the two clamping bodies for positioning the seat arch of the seat cushion; the angle between the two sets of clamping members and the seat tube can be fixed under the locking of the bolt At the same time, the two sets of clips are respectively clamped and fixed, and the purpose of locking the seat 塾* to the top of the seat tube is achieved by φ. However, once the bolts in these conventional locking structures are loosened, the locking action between the two sets of clips and the seat tube is simultaneously removed, and the two sets of clips are used to make the clips of the seat bows. The interference between the two sets of clamps and the seat tube and between the clamps of the two sets of clamps is lost, and the locking effect is not reliable, especially when the angle of the seat cushion is adjusted, the sheet is continuously loosened and rotated. It will cause operational inconvenience. Therefore, another kind of locking structure appears on the market surface, and a plurality of tooth-like structures are formed on the contact surface between the seat tube and each set of clips, so as to be engaged with each other to form a clamping position of the seat tube and each set of clips, and each tooth is positioned. Although the shape structure can constitute a sandwiching function, the molding process is complicated. [New content j In view of this, this creation aims to provide a relatively more reliable bicycle, and a locking structure that facilitates the adjustment of the angle of the seat cushion, as its main purpose. In order to achieve the goal, this creation "the locking structure of the bicycle seat cushion is provided with a shaft seat at the top of the seat tube of the seat, and the shaft hole of the shaft seat"; there is a set of lost parts in the armature', and another locking shaft is locked on the shaft. 3 sets of clips and two sets of missing pieces are made up of two clips for clamping the seat bow of the seat and a spring between the two pieces for normal clamping of the two pieces. The body produces - the force pushing away from each other. The whole set of locking structure can 'fix the angles of the two sets of the e-pieces' after the locking shaft is locked, and the two sets of clips respectively clamp the seat arches to fix the seat cushions to the top of the seat tube. . And, when the locking shaft is relaxed, the clamps of each group open the two clamping bodies relative to each other under the action of the spring for convenient adjustment of the angle of the seat cushions, and under the push of the spring, the sets of the cooling elements are located inside. The clamping body can still maintain an interference with the shaft seat, effectively preventing the clamping member from loosening and rotating at will, and the inner clamping body and the outer clamping body still have an axial displacement space, and the seat cushion can be directly oriented at a predetermined angle. Pulling, the convenience of the angle adjustment of the seat cushion is further improved. The second purpose of the present invention is to provide a plurality of interlaced clamping blocks on the bonding surfaces of the two clips of each set of clips. When the two clips are attached to each other, the interlaced clamping blocks are used. The seat arch is clamped and fixed, so it is less suitable for the whole set of locking structure than the shape and size of the seat bow. [Embodiment] The features of the present invention can be clearly understood by referring to the detailed description of the drawings and the embodiments. As shown in the first to third figures, the "locking structure of the bicycle seat cushion" includes: a shaft seat 10, two sets of clip members 20, and a locking shaft 30; wherein; the shaft seat 1〇 The sleeve 10 can be integrally disposed on the top of the seat tube 40 of the bicycle, and the shaft seat 10 is provided with a concave portion 214 on the side of the clamp body 21, and the concave portion 214 can be in contact with the spring 22 for positioning to prevent arbitrarily loosening. The horizontal hole 11 is horizontally disposed, and the two ends of the shaft hole can be tapered to increase the joint effect of the two sets of the clamp member 20 and the shaft seat 1 . The two sets of clips 20 are respectively mounted on the shaft end of the shaft seat 1〇 and the contact surface of the shaft seat 10 and each set of clips 2 is a smooth surface and no toothed structure is provided. The clamping member 2 is composed of two clamping bodies 21 for clamping and fixing the seat arch 51 of the seat cushion. The two clamping bodies 21 of each set of clamping members 2 are respectively provided with a through hole 211, and two sets of the clamping members 20 are respectively provided. The clip body 21 is respectively provided with a flange 213 ′, wherein the shaft seat 1 设有 is provided with a groove 12 at the flange 213 so that the flange 213 and the groove 12 can be engaged with each other. The shaft seat 1 〇 has a limiting function; the clamping surfaces of the two clamping bodies 21 of each group of clamping members 20 are respectively provided with a plurality of staggered clamping blocks 212 for clamping and fixing the seat cushion 51 of the seat cushion. The clamping body 21 of each set of clips 20 has a taper that matches the two ends of the shaft hole 11 of the shaft seat 1; and each set of clips 2 is provided between the two clip bodies 21 thereof. The spring 22 is used to generate a force for pushing the two pieces of the clamping body 21 in a normal state. The locking shaft 30 is locked between the shaft seat 10 and the two sets of clamping members 30. The locking shaft 30 is formed by a shaft 31 and a bolt 32. The shaft 31 is One end of the spindle end is provided with a screw hole 3U, and the shaft 31 penetrates into the shaft hole 11 of the shaft base 10 and the through hole 211 of the clamp body 21, and is locked into the screw hole 311 of the shaft 31 by the bolt 32. The locking shaft 3 is slidably locked between the shaft seat and the two sets of clips, and after the shaft 31 and the bolt 32 are locked, the angle between the two sets of clips 2G and the seat tube 4Q can be fixed, and at the same time The two sets of clips respectively fix the seat arch clip 51 of the seat to achieve the purpose of locking the seat to the top. s and, when the shaft 31 of the locking shaft 30 and the bolt 32 are relaxed, the components 20 are caused by the spring 22 to open the two clamping bodies, and the springs 22 are pushed down, and the sets of the clamping members are respectively The 2G inner clamping body 21 can still maintain interference with the seat 10, which can effectively prevent the clamping member 2G from loosening at any time, and the entire locking structure is more reliable. β In particular, when the shaft 31 of the locking shaft 30 and the bolt 32 are relaxed, under the pushing of the spring 22, the clamping body 21 on the inner side of each set of clamping members 2 and the outer clamping body a still maintain an axial displacement space. The groove 12 provided by the shaft seat is a long arc groove, and the flange 213 can be slid in the groove 12. Please refer to the fourth figure at the same time, directly facing the seat cushion 50 before and after the predetermined position. The position or the predetermined angle can be adjusted to achieve the purpose of adjusting the front and rear position or angle of the seat cushion, and the movement of the flange 213 can be restricted by the groove 12 to further control the sets of the clips 20 and the seat 5塾. The angle of rotation of the shaft seat 1〇. It is worth mentioning that the bonding surfaces of the two clamping bodies 21 of each set of clips 2 are respectively provided with a plurality of clamping blocks 212 arranged in a staggered configuration as shown in the second figure, when the two clamping bodies 21 are mutually When fitting, the seat arches of the seat are clamped and fixed by the interlacing clamps 212, instead of using the fixed pitch grooves to position the seat arch, so it is less than the shape and size of the seat bow. Restrictions make the entire set of locking structures more suitable. Therefore, compared with the conventional locking structure, the author has the following advantages: 1. When the angle of the seat cushion is adjusted, the M382239 clip body of each group of clips can still maintain an interference limit with the shaft seat. Effectively prevent the clip from being loose or rotated. 2. The creation of the lock structure by the shaft-and-bolt phase is used to disperse the shearing force on the locking shaft during use, reducing the risk of breakage due to = and reducing the risk of the seat cushion being loose. In order to maintain the driving safety 3, the contact surface between the shaft seat and each set of clips in this creation is a smooth watch, and no toothed structure is provided.
