Abstract

The utility model provides a bicycle hook structure for supporting a bicycle wheel axle. A through hole for locking other components and for screws to pass through is provided on the hook body. The utility model is characterized in that a rotation-stopping wall is separated at one end of the through hole edge, and the rotation-stopping wall is used to limit the rotation of one of the screw head or nut abutting against the rotation-stopping wall, thereby making it easier to operate when locking other components on the hook.

Description

Bicycle dropout structure

【Technical field】

The utility model relates to a bicycle claw structure, especially a perforation for locking other components with the claw. The edge of the perforated hole at one end is provided with a non-rotation wall that can limit the rotation of nuts or screws. The bicycle dropout structure is relatively easy to operate when locking other components. the

【Background technique】

Bicycles can not only be used for transportation, exercise and fitness, but also have energy-saving and carbon-reducing effects, so people often see people riding bicycles. For driving safety, the bicycle is equipped with a brake device on the front and rear wheels. The brake device is a disc brake. The disc brake disc is fixed on the wheel shaft and rotates synchronously with the wheel shaft. The disc brake seat that produces a braking effect on the disc brake disc is It is fixed on the dropout for supporting the axle. The structure of the hooks fixing the disc brake seat is to set a vertical perforation on the hook. When the disc brake seat is overlapped on the hook, use the screw to pass through the fixing hole of the disc brake seat and the hole of the hook claw from top to bottom. Finally, a nut and a screw are screwed under the hook claw to fix the disc brake seat on the hook claw. When locking the disc brake seat, the screw and the nut can be rotated flexibly. When locking, the operator needs to hold a tool in each hand to lock the screw and the nut. This is more troublesome for the locking operation. , Take a lot of work. the

【Content of utility model】

The main purpose of the utility model is to provide a bicycle hook structure that can be used to lock other components on the hook. the

The main feature of this structure is that the claw body is used to lock other components and pass through holes for screws. There is a rotation-stop wall at one end of the hole, which is used to limit the screw head that is in contact with the rotation-stop wall. Or one of the nuts rotates, thus, it is convenient to lock other components on the claw, so that the locking operation saves trouble and labor. the

A bicycle hook structure, used to support the bicycle wheel shaft, on the hook body, there is a perforation for locking other components and allowing screws to pass through; it is characterized in that: there is a non-rotation wall at the edge of the hole at one end of the perforation, The anti-rotation wall is used to limit the rotation of one of the screw head or the nut abutting against the anti-rotation wall. the

Wherein, the anti-rotation wall is three walls, and the three walls cooperate with one of the screw head or the nut to abut against to limit the rotation of the screw head or the nut. the

Wherein, the anti-rotation wall is six wall surfaces, and the six wall surfaces are partitioned into an inner hollow shape for embedding one of the screw head or the nut to limit its rotation. the

The advantages and effects of the utility model are: the main feature of the structure is that the claw body is used to lock other components and pass through holes for screws, and there is a stop wall at the edge of the hole at one end of the holes to limit the contact with the hook. One of the screw heads or the nuts abutted against the anti-rotation wall rotates, thereby facilitating the locking of other components on the claw, which saves trouble and labor in the locking operation. the

The labels in the figure are explained as follows:

Hook 1 Hook body 10 Component 30

【Detailed ways】

Please refer to Figures 1 and 2, the hook 1 of the embodiment of the present invention is a hook body 10 used to lock other components 30 (such as a disc brake seat) and a through hole 11 for a screw 21 to pass through. One end of the hole edge is partitioned with an anti-rotation wall 12 (please refer to the bottom view of the claw shown in FIG. 3 ), which is used to limit the heads of screws 21 (as shown in FIG. 5 ) or nuts 20 (as shown in FIG. 5 ) abutting against the anti-rotation wall 12 ( As shown in Figure 2) one of them rotates. The anti-rotation wall 12 can be three walls (as shown in Figure 3 ) that match the shape of the head of the screw 21 or the nut 20, or it can be six walls, and the six walls are divided into an inner hollow shape for the screw head or the nut. One of them fits into the stop. the

With the design of the hook 1, no matter the head of the screw 21 abuts against the anti-rotation wall 12, or the nut 20 abuts against the anti-rotation wall 12, when other components are locked, one of the nut 20 or the screw 21 can be locked. The anti-rotation wall 12 restricts rotation. When locking other components, the screw 21 and the nut 20 can be locked and tightened with only one tool in hand. The locking operation is very convenient and labor-saving (as shown in FIG. 4 ). the
