New description: [New technical field], reliable and safe. This creative department is related to the type of bicycle seat lock structure, especially the bicycle seat cushion which is convenient to adjust the seat cushion angle and relatively stable. Locking structure [Prior Art] Press, the bicycle seat cushion is mainly used to support the rider's body weight, so that the rider has to step on the pedal 'and the basic comfort · Because the bicycle seat cushion must take the rider Because of the downward pressure generated by the weight and the upward movement of the ground through the wheel to the seat bracket (4), the seat cushion and the vehicle body must have better locking strength. The seat cushion is usually a locking structure: the seat bow at the bottom of the seat and the seat tube of the bicycle are locked and combined, but the locking structure with the adjustment function is between the bow and the seat tube. In order to meet the riders of various sizes, the ride comfort is better. For example, 'National No. 1284097, No. M313629, No. m and % 唬, No. 3% 专利. There is a set or two sets of clips, and then bolts are locked in the seat two: two) between the two sets of clips corresponding to each other; and each set of clips is composed of nit sheets attached to each other, and the inner and outer clips The groove on the fitting surface is respectively provided for the positioning of the seat bow of the seat; the 俾 can be fixed under the locking of the screw inspection = the angle between the clamp and the returning, and the two sets of missing parts respectively LJ疋, in order to achieve the purpose of locking the seat cushion to the top of the seat tube. M383516 However, the same feature of these conventional locking structures is that the two sets of clamps on the two sides of the seat tube are locked by a single bolt, which not only has poor locking effect, but also has unreliable structural strength; especially when the bolt After being loosened, the two sets of clips corresponding to each other on both sides of the seat tube are arbitrarily rotated relative to each other, so that when the angle of the seat cushion is adjusted, the continuously loose and rotating sheet body may cause operational inconvenience. [New content] In view of this, the purpose of this creation is to provide a locking structure that is relatively more reliable and convenient to adjust the angle of the seat cushion, and its main purpose. In order to achieve the goal, the bicycle seat cushion locking structure is provided with a shaft seat at the top of the bicycle seat tube. The shaft holes of the shaft seat are respectively provided with a set of clips, and two bolts are parallel to each other. The side-by-side arrangement is locked between the shaft seat and the two sets of clamp members; wherein each set of clips is composed of inner and outer clips for clamping and fixing the seat cushion of the seat cushion, and clips of each set of clips are clipped The utility model is provided with a screw perforation and a screw hole, and a spring is arranged between the inner and outer clips to normally exert a pushing force on the inner and outer clips. The whole set of locking structure can fix the angle between the two sets of clips and the seat tube after the two bolts are locked, and at the same time, the two sets of clips respectively clamp the seat arch to achieve the locking of the seat cushion on the top of the seat tube. The purpose. And when the two sets of bolts are relaxed, each set of clips is caused by the spring to make the inner and outer clips relatively open, which is convenient for assembling the seat cushion, and under the push of the spring, the clips of each set are located inside the clip. It can still maintain an interference with the shaft seat, effectively prevent the clip from loosening and rotating at will, and under the action of the two bolts, limit the two sets of clips corresponding to the phase M383516 to rotate with each other' The outer clip can still maintain the axial displacement space', which can directly move the seat cushion toward a predetermined angle, thereby improving the convenience of adjusting the angle of the seat cushion. The second purpose of the present invention is to provide two stopping portions in the shaft hole of the shaft seat, and the stopping portion is disposed at a position opposite to each bolt for rotating each group of the clamping members to a predetermined angle. The screw inspection constitutes interference and limits the angle adjustment of the seat raft in a safe range to increase the riding safety of the bicycle. • [Embodiment] The characteristics of this creation can be clearly understood by referring to the detailed description of the drawings and the examples. As shown in the first to fourth figures, the "bike seat cushion locking structure" of the present invention includes: a shaft seat 10, two sets of clip members 20, and two bolts 30; wherein: the shaft seat 10 can be integrated The shaft seat 10 is disposed at the top of the bicycle seat tube 40, and the shaft seat 10 is provided with a horizontally disposed shaft hole 11 and the shaft hole 11 has a cone 10 degrees at both ends. Further, the shaft hole 11 is provided with two stopping portions 111. . The two sets of clips 20 are respectively installed at the two ends of the shaft hole 11 of the shaft base 10, and each set of clips 20 is used by the inner and outer clips 21 and 22 to fix the seat arch 51 of the seat cushion. The clips 21 of each set of clips 20 are provided with a through hole 211. The clips 2 2 of each set of clips 20 are provided with a screw through hole 21 and a screw hole 222, and the inside and outside of each set of clips 20 are provided. The clamping faces of the clips 21 and 22 are respectively provided with a plurality of staggered clamping blocks 23 for clamping and fixing the seat arches 51 of the seat cushions. The clips 21 of the respective sets of clips 20 have the same 1 〇 shaft hole 11 5 M383516 Both ends of the matching taper to increase the joint effect of the two sets of clips 2 〇 and the shaft seat 10; and 'each set of missing pieces 20 between the inner and outer clips 21, 22 A spring 24 is provided for generating a force for pushing the inner and outer clips 21, 22 in a normal state. As for the two bolts 3, the two bolts are locked in the parallel arrangement of the shaft seat 10 and the two sets of clamps 2, and the two bolts 3 are respectively arranged by the outer sides of the two sets of clamps 20 Through the screw hole 221 of the outer clip 22, the through hole 211 of the inner clip 21, the shaft hole I of the shaft seat 1 ,, and the through hole 211 of the inner clip 21 of the other set of clips 2 After the screw hole 222 of the outer clip 22 is inserted, and after the bolt 30 is locked, the angle between the two sets of clips 2〇 and the seat tube 4〇 can be fixed, and at the same time, the two sets of clips 2〇 respectively place the seat cushion of the seat cushion 51 is clamped to ensure that the seat cushion is securely mounted to the top of the seat tube. And when the two bolts 3〇 are relaxed, each set of clips 2 turns the inner and outer clips 21, 22 relatively open under the action of the spring 24, and under the push of the spring 24, the sets of clips Within 20, the clip 21 can still maintain an interference with the shaft seat 1〇, which can effectively prevent the clip 20 from being loosened and rotated at will, and the whole set of locking structure is more reliable. In particular, under the action of the two bolts 30, the corresponding two groups can be restricted, and the pieces 2Q rotate with each other, and the inner and outer clips 21, 22 of each set of lost parts 2G can still maintain the axial displacement space. The seat cushion is directly pulled toward a predetermined angle, which further improves the convenience of the angle adjustment of the seat cushion. And the stopping portion 111 is disposed at a position below the bolts 30. As shown in FIG. j, when the respective sets of the lost pieces 20 and the bolts 30 are rotated counterclockwise, the thread check 30 is subjected to the lower stop portion thereof. 111 interference can not continue to turn M383516. The opposite is true - # each group of clips 20 and each bolt 3 〇 Shun six figure, the other - bolt 30 will be hit by the bottom of it, if it can not continue to rotate, so when The clamping member 2 turns more than the safety interference, and the blocking portion U1_ of the shaft seat H) is twisted into interference: ^ can be continuously rotated in the direction to limit the seat in the safe range: 2: When the screw is in the process of traveling, if the angle of the 塾 is adjusted, the structure of the 塾 can also be limited.
