Abstract

The utility model discloses a bicycle bracket which comprises a fixation piece, a movable connecting piece, a support leg, a spring or the like, a heaved face is arranged at the bending position at the other end of the fixation piece relative to the installing groove, the side face at the lower end of the fixation piece is extended to the positive surface which is provided with a rectangular hole, a certain distance is kept between the lower end of the rectangular hole and the side edge. The side face and the positive face of the upper end of the movably connecting piece curve inwards to form a right-angle claw with proper length, the claw is clipped inside the rectangular hole of the fixation piece under the action of the spring. The heaved face of the fixation piece of the bicycle bracket prolonged and widened to the maximal range has longer length than the sum length of the heaved face along the curving line and the higher rigidity at the curving position compared with the prior art. Based on that the claw of the movable connecting piece is of right angle, the utility model achieves higher bending-resistant rigidity and endurance compared with the current surface claw of the movably connecting piece.

Description

Cycle rack

Technical field

The utility model relates to the cycle rack that a kind of single leg supports.

Background technology

The normally used a kind of form of existing cycle rack is the cycle rack that two crownings are arranged, and comprises connecting element, active connection, supporting leg, spring etc.The inclination of bicycle is for the benefit of placed, wherein connecting element need be bent into two faces with certain angle, be provided with greatly in the bending place of two faces, the small embossment face, play reinforced rib, in the prior art, this big crowning is positioned at an end bending place of connecting element, this crowning is less than normal along the length of folding line, makes the intensity of this bending place lower, for further improving intensity, the bending place of the suitable distance of the big crowning of distance is provided with the small embossment face again, even now, the bending place intensity of this structure are still not enough, usually damage easily in the use, this complex structure makes the processing trouble simultaneously.The upper end, side of active connection extends upward the claw of projection, this claw is stuck in the rectangular opening of lower end, connecting element side under the effect of spring, make supporting leg be in suitable position and support bicycle, the cross section of this claw is the plane, its flexing resistance is poor, when active connection frequently used, this claw often was damaged.

The utility model content

For overcoming the defective that above-mentioned prior art exists, the purpose of this utility model provides a kind of durable cycle rack.

For realizing the purpose of this utility model, the utility model cycle rack comprises connecting element, active connection, supporting leg, spring etc., the bending place of the relative mounting groove other end of described connecting element is provided with a crowning, the above parts transversely of the folding line of this crowning extends to apart from the shortest required position, mounting hole edge, vertically extend upwardly to the top, this crowning extends to apart from supporting leg fraising the shortest required position along the parts transversely below the folding line, vertically extend downward the position of about supporting leg fraising, be positioned at the ream edge arc transition of crowning top and the bottom of a side of mounting hole and supporting leg and be connected to form the trapezoidal edge of joint, the other end of crowning extends laterally to edge and the inwardly approximately vertical crimp that bends a proper width, the side of this connecting element lower end extends to the front one rectangular opening is set, and this rectangular opening leaves suitable distance apart from lower end and lateral edge.The side of described active connection upper end and the right angle claw of the positive suitable length that bends to the inside, this claw is stuck in the rectangular opening of connecting element under the effect of spring, makes the supporting leg of bicycle be in suitable Support Position.

The cycle rack that adopts said structure is because the lengthening of the crowning maximum range of this connecting element and widening, crowning than prior art is big along the length summation of folding line, then the intensity of this bending place is many greatly, because the claw cross section of active connection is the right angle, compare with the claw of the planar cross-sectional of the active connection of prior art, its bending strength is much bigger, and this cycle rack is durable.

The specific embodiment

As Fig. 1,6,7,8,9,10,11, shown in 12, this cycle rack comprises connecting element 1, active connection 2, supporting leg 3, spring 4 etc., the bending place 11 of described connecting element 1 relative mounting groove 16 other ends is provided with a crowning 14, part one end of the folding line of this crowning 14 more than 11 extends laterally to apart from the shortest required position at mounting hole 15 edges, extend longitudinally to the top, this crowning 14 extends laterally to apart from the supporting leg 12 the shortest required positions of reaming along part one end of folding line below 11, extend longitudinally to the position of about supporting leg fraising 12, the edge arc transition of the top and the bottom of crowning 14 is connected to form the trapezoidal crowning 14 of joint, the other end of crowning 14 extends laterally to edge and the inwardly approximately vertical crimp that bends a proper width, the side of this connecting element 1 lower end extends to the front one rectangular opening 13 is set, and this rectangular opening leaves suitable distance apart from 13 lower ends and lateral edge.The claw 21 of the square of the side of described active connection 2 upper ends and the positive suitable length that bends to the inside, this claw 21 is stuck under the effect of spring in the rectangular opening 13 of connecting element 1, makes the supporting leg 3 of bicycle be in suitable Support Position.
