Description

M264206 4. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation relates to the improvement of the joint structure between the front fork shoulder and the handlebar of a bicycle. Angular joint construction. [Previous technology] According to the general, the front wheel of the bicycle is mainly used to control the balance and steering of the bicycle, so basically the front wheel and handlebar of the bicycle are mainly connected through the front fork shoulder seat, in order to turn the bicycle handlebars, The front wheel can swing with the handle to achieve smooth steering and balance control. Therefore, the front fork shoulder of the bicycle and the handle are mainly tied in the middle of the fork shoulder and the middle of the handle to form a connection to achieve the purpose of front wheel steering and avoid Causes difficulty in handling. As shown in the first and second figures, this is an external perspective view of a conventional fork shoulder and handlebar joint structure used in common bicycles. Among them, the bicycle is provided with a hollow rage rod 1 1 in the middle position of the fork shoulder. 'And a locking block 31 and a front extension tube 32 constitute the connection between the front fork shoulder 10 and the handle 20, and the inside of the core rod 1 1 is pressed into a flower piece 12 and the flower piece 12 is A stud 1 2 1 with internal threads is provided, and the shaft center of the locking block 3 1 and the core rod 11 is provided with a perforation 7 2, and a core rod 7 3 and a cover sheet 7 4 pass through the perforation 7. 2 is screwed with the stud 1 2 1 of the flower piece, and the cover piece 7 4 is pressed above the lock block 3 1 so that the lock block 3 1 is positioned on the upper bearing 14 above the core rod 1 1 to form The connection between the locking block 31 and the front fork shoulder 10, and a pair of pivot ears 3 1 2 is extended in front of the locking block 31, and there is a sleeve hole 3 1 extending between the two pivot ears 3 1 2. 1 of

M264206 4. Creation instructions (2) Gap 3 1 3, one end of the front 'extend tube 3 2 is fixedly connected to the handle 2 0, and the other end is provided with a pair of clip ears 3 2 clamped on the outside of the pivot ear 3 1 2 1 and another bolt 6 4 is threaded between the clamp ear 3 2 1 and the pivot ear 3 1 2 to form the connection between the front extension tube 3 2 and the locking block 3 1 to reach the handle 20 and the front fork shoulder seat. The coupling effect between 10 and the locking effect of the release bolt 6 4 can be used to properly move the clamp ear 3 2 1 and the pivot ear 3 1 2 so that the handle 20 has an adjustable angle. Features. However, the conventional joint structure cannot adjust the height of the handle 20, that is, bicycles of the same specification will feel that the position of the handle is not suitable or the handle angle cannot be applied due to the difference in the rider's body, which will cause restrictions on the applicable objects, and the pivot ear 3 1 2 is arranged forward to the front of the locking block 3 1, so the angle adjustment of the handle is swung up and down by the front extension tube 3 2, not only the adjustment angle is limited, especially under the pressure of the rider's body weight , It is easy to cause changes in the angle of the handle, which in turn affects the safety of riding. [New content]-The main purpose of this article is to provide an adjustable height of the handlebar through the setting of the sleeve and the shaft. At the same time, the handlebar can be adjusted by the angle adjustment structure. With the function of adjusting the angle. In order to achieve the above purpose, before this creation, the head tube of the frame in the middle of the fork shoulder seat is connected with the handle riser and the handle; among them, a core rod is provided in the middle of the fork shoulder seat and the head tube of the frame. A sleeve is plugged in. Concave and convex tooth blocks are respectively provided on the two sides of the sleeve, and a shaft is provided above the sleeve. One end of the sleeve is provided with an arc tooth block that engages with the concave and convex tooth block. The tube is fixedly connected to the handle, and another two clamped solids are fixed to the arc-shaped teeth by using a fixing member.

M264206 IV. Creation instructions (3) The block corresponds to the bottom of the concave-convex tooth block, and the two sandwich solids and the concave-convex tooth block are on one side to form concave-convex teeth that engage the concave-convex tooth block. The arc-shaped tooth block and the two clamped solids are closely pressed against the concave-convex tooth block to form a connection between the shaft and the sleeve, and the sleeve and the core rod are inserted into each other to form a connection between the front fork shoulder seat and the handle. [Implementation] In order to make your reviewing committee clear about the structure and composition of this creation, as well as the overall operation mode, the following explanations are given in conjunction with the drawings:

In this work, "Bicycle handlebar angle adjustment and heightening structure", its connection structure is also tied in the middle of the front fork shoulder and the middle position of the handle to form the connection between the front shoulder and the handle, as shown in Figures 3 and 4. Among them, a frame head tube 1 3 is arranged in the middle of the bicycle's front fork shoulder seat 10, a core rod 1 1 is arranged in the frame head tube 13 and a core rod 1 1 is arranged above the core rod 11 Sleeve 41, which can be inserted into the core rod 11, and a cut groove 4 1 1 is provided at the sleeve end of the sleeve 41, and the cut groove 4 1 1 is along the sleeve. The axial extension of the tube 41 has a predetermined length, and corresponding lugs 4 1 2 are provided on both sides of the cut groove 4 1 1, and a sleeve is screwed between the corresponding lugs 4 1 2 to place the sleeve. 4 1 tightening screws 4 2, and the two sides of the sleeve 4 1 are integrally formed with concave and convex tooth blocks 4 3, and a shaft 5 is arranged above the sleeve 4 1, and one end is provided with an arc tooth block 5. 1 '

On the other end, a handle standpipe 30 composed of a locking block 31 and a front extension tube 32 are fixedly connected to the handle 20, and the other two clamps 60 are fixed using a fixing member. In this embodiment, bolts 71 are mainly used for fixing. The arc-shaped tooth block 5 1 corresponds to the concave-convex tooth block 4 3, and the arc-shaped tooth block 5 1 and the two clamped solid pieces 60 and the concave

Page 7 M264206 IV. Creation instructions (4) Convex tooth block 4 3 is attached to the 'side', and concave and convex teeth 7 5 are formed to mesh with the concave tooth block 4 3 to make the bolts 7 1 arc-shaped tooth blocks. 5 1 and two clamp solids 60 are closely pressed against the concave-convex tooth block 4 3 to form a connection between the shaft 50 and the sleeve 41, and then the sleeve 41 and the core rod 11 are inserted and tightened with each other through the sleeve 4 1 The function is to form the connection between the fork shoulder 10 and the handle 20 before the bicycle. In the specific implementation, please refer to the fifth figure at the same time. The core rod 11 of the front fork shoulder seat 10 is pressed into a flower piece .12, and a screw with an internal thread is provided in the flower piece 12. Column 1 2 1, the sleeve 41 and the core of the shaft 11 are provided with a perforation 7 2, and a core rod 7 3 and a cover piece 7 4 pass through the perforation 7 2 and the stud of the flower piece 1 2 1 Screwed, press the cover 7 4 over the sleeve 4 1 to position the sleeve 4 1 on the upper bearing 1 4 above the core rod 1 1, and then use the clamping ear 4 1 2 and the bolt 4 2 to The sleeve 41 is fixed on the core rod 41 and forms a connection between the sleeve 41 and the front fork shoulder 10. -It is worth mentioning that the height of the handle 20 can be increased through the setting of the sleeve 41 and the shaft 50, and the arc tooth block 5 1 and The loosening effect of the two clamped solids 60 on the concave-convex tooth block 4 3 enables the handle 20 to increase the height and adjust the angle. As shown in the sixth figure, the user can adjust the handle in real time as needed. Angle and height, without restricting the riding object because the handle angle and height cannot be adjusted. As mentioned above, this creation provides another better and feasible joint structure of the bicycle front fork shoulder seat and handlebars, and applies for a new patent application according to law; however,
