Carbon fiber bicycle front hook claw structure

Technical Field

The utility model relates to a bicycle technical field, in particular to carbon fiber bicycle hook structure before.

Background

The existing bicycle frame needs to reduce the weight of the frame in order to increase the running speed, so the frame is made of carbon fiber materials by utilizing the advantages of light weight and texture of the carbon fiber materials. However, the joint between the frame and the front wheel or the rear wheel must have sufficient strength to provide the bearing and supporting functions, and the hook made of carbon fiber is hard and brittle and is easily broken, so a metal part is usually disposed at the joint between the wheel and the hook. The existing metal piece is generally installed in the hook claw in an embedded mode, and the metal piece is locked and fixed through screws and the like after being installed in an embedded mode.

Disclosure of Invention

To the technical problem who exists among the background art, the utility model aims to provide a can realize automatic alignment and can make metalwork and collude the carbon fiber bicycle front hook claw structure that the claw closely cooperates.

In order to realize the purpose, the utility model discloses a technical scheme as follows:

the utility model provides a collude claw structure before carbon fiber bicycle, includes that metalwork and carbon fiber collude the claw seat, one side that the carbon fiber colluded the claw seat seted up with metalwork shape looks adaptation can supply the mounting groove that the metalwork imbeds completely. The metal piece comprises a body part and a boss extending downwards from the bottom of the body part, a through hole completely penetrating through the body part and the boss is formed in the metal piece, and an internal thread is arranged on the inner wall surface of the through hole. The bottom of the mounting groove is provided with a mounting hole for the boss to be inserted into, the outer surface of the boss is provided with a first conical surface, and the inner wall surface of the mounting hole is provided with a second conical surface matched with the first conical surface.

Furthermore, in order to enable the connection between the metal piece and the front hook claw to be more stable and reliable, one end, far away from the through hole, of the body part is fixedly connected with the hook claw seat through a screw.

The bottom of the mounting groove is provided with a threaded hole, the top of the body part is provided with a screw groove, and the bottom of the screw groove is provided with a through hole for the screw to pass through right above the threaded hole.

Preferably, in order to facilitate the alignment and installation of the screws, the through holes are elongated holes.

Further, the thickness of the metal piece is 9-10 mm, and the height of the boss is 5-6 mm.

Preferably, the conicity of the first conical surface and the conicity of the second conical surface are both 4-6 degrees.

Preferably, in order to further reduce the overall weight of the bicycle frame on the premise of ensuring the strength, the metal piece is made of aluminum alloy.

The utility model discloses following beneficial effect has: the front claw structure of the carbon fiber bicycle is provided, the joint of the metal piece and the claw seat adopts a conical surface matching design, the center can be automatically aligned, and the locked metal piece and the carbon fiber claw seat are tightly matched; the metalwork adopts a fix with screw, because little screw thread on the carbon fiber adopts to draw the cap to adhere the mode, and the precision is not good, through being the rectangular hole with the through hole design, can be so that the installation of screw is quick more and convenient, reduces the precision of little screw.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1-6, a carbon fiber bicycle front hook structure comprises a carbon fiber hook seat 1 and a metal piece 2, wherein the metal piece 2 is preferably made of aluminum alloy. One side of the carbon fiber claw seat 1 is provided with an installation groove 10 which is matched with the shape of the metal piece 2 and can be used for completely embedding the metal piece 2. The metal part 2 comprises a body part 21 and a boss 22 formed by extending downwards from the bottom of the body part 21, a through hole 20 completely penetrating through the body part 21 and the boss 22 is formed in the metal part 2, and an internal thread is arranged on the inner wall surface of the through hole 20. The bottom of the mounting groove 10 is provided with a mounting hole 11 for inserting the boss 22, the outer surface of the boss 22 is provided with a first conical surface 220, and the inner wall surface of the mounting hole 11 is provided with a second conical surface 110 matched with the first conical surface 220.

The thickness D of the metal piece 2 is 9-10 mm, and the height H of the boss 22 is 5-6 mm. Preferably, the conicity of the first conical surface 220 and the second conical surface 110 is 4-6 degrees.

One end of the main body 21, which is far away from the through hole 20, is fixedly connected with the claw seat 1 through a screw 3, a threaded hole 12 is formed at the bottom of the mounting groove 10, a screw groove 210 is formed at the top of the main body 21, and a through hole 211 for the screw 3 to pass through is formed at the bottom of the screw groove 210 right above the threaded hole 12. Preferably, the through-hole 211 is a long hole.

When the metal piece 2 of the utility model is arranged on the claw hooking seat 1, the automatic center alignment can be realized under the matching of the first conical surface 220 and the second conical surface 110, and the locked metal piece 2 and the claw hooking seat 1 can be tightly matched; the metal piece 2 is fixed by the screw 3, and the through hole 211 is designed to be a long hole, so that the screw 3 can be installed more quickly and conveniently, and the accuracy of the screw 3 is reduced.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
