Description

Technical Field

[0001] The utility model belongs to the technical field of bicycles, and particularly relates to a detection device for the front support of a bicycle. Background Art

[0002] A bicycle is a land vehicle driven by human pedaling and having two wheels, commonly known as a free bicycle, a pedal bicycle or a bicycle. Since its birth, the bicycle has become the best choice for people's sports and environmental protection travel. It has the characteristics of no noise, no pollution, light weight, simple structure, good quality and low price, convenient use and maintenance, etc. It can be used as a tool for commuting and carrying goods, and can also be used for physical exercise. The bicycle handlebar is a key component for controlling the driving direction of the bicycle, and its balance and stability directly affect the riding safety and riding experience. During the riding process, a slight deviation of the bicycle handlebar may cause a deviation in the driving trajectory. Especially under high-speed driving or complex road conditions, such a deviation may bring serious safety hazards.

[0003] Currently, in the installation and adjustment of traditional bicycle handlebars, it is usually relied on human experience and visual observation to judge whether the handlebar is horizontal and perpendicular to the front wheel. This method has problems such as low installation and adjustment accuracy and inability to perform precise detection, which is not only inefficient, but also difficult to ensure the accuracy and consistency of the detection results. At the same time, due to the interference of human factors, there are often certain errors in the detection results. Based on the above problems, this application document proposes a detection device for the front support of a bicycle to improve the above problems. Content of the Utility Model

[0023] In order to make the purpose and advantages of the utility model more clear, the following takes embodiments as examples to specifically describe the utility model. It should be understood that the following text only describes one or several specific implementation manners of the utility model, and does not strictly limit the scope of protection specifically claimed by the utility model.

[0024] As Figures 1 to 4As shown in the figure, a detection device for the front support of a bicycle includes a base 10. A fixing mechanism 15 is assembled at the upper end of the base 10. U-shaped frames 11 are fixed on both sides of the fixing mechanism 15 at the upper end of the base 10, and the two U-shaped frames 11 are parallel to each other. Telescopic mechanisms 20 are fixed at the upper ends of the two U-shaped frames 11. A support plate 25 is fixed at the upper ends of the two telescopic mechanisms 20. Slide rails 26 are fixed at both ends of the upper end of the support plate 25. A partition 27 is fixed between the two slide rails 26 at the upper end of the support plate 25. First scale rulers 28 are fixed at the upper ends of the two slide rails 26. First T-shaped grooves are opened at both ends inside the slide rails 26. Sliders 29 are slidably connected inside the two first T-shaped grooves. A pointer 30 and a support block 31 are sequentially fixed at the upper ends of the two sliders 29 from one side to the other side, and the pointer 30 is located on the side close to the first scale ruler 28. A contraction housing 32 is fixed on the side of the support block 31 away from the pointer 30. A second T-shaped groove is opened inside the contraction housing 32. A measuring plate 33 is slidably connected inside the second T-shaped groove. A fixing knob 34 is rotatably connected to one end of the contraction housing 32. A second scale ruler 35 is fixed at one end of the measuring plate 33 and close to one end of the fixing knob 34.

[0025] As Figure 5 and Figure 6 shown, the fixing mechanism 15 includes a fixing plate 16, a fixing block 17, a threaded rod 18 and a handwheel 19. The fixing plate 16 is fixed at the upper end of the base 10, and a third T-shaped groove is opened inside the fixing plate 16. The fixing block 17 is slidably connected inside the third T-shaped groove. The threaded rod 18 is rotatably connected to one end of the fixing block 17, and the threaded rod 18 is threadedly connected to the fixing plate 16. The handwheel 19 is fixed at one end of the threaded rod 18 and away from the fixing block 17.

[0026] Furthermore, an anti-slip rubber sleeve is sleeved outside the handwheel 19. A number of anti-slip lines are evenly opened on the outside of the anti-slip rubber sleeve. The anti-slip lines provide additional friction, enabling the handwheel 19 to be firmly held. Secondly, it is not easy to slip off when operating the handwheel 19, reducing the accidental risk caused by hand slipping. At the same time, the anti-slip lines can disperse the pressure on the surface of the handwheel 19 and reduce the wear caused by long-term holding.

[0027] As Figure 1 and Figure 2 shown, a support plate 12 is fixed on one side of the base 10. A level 13 is fixed at the upper end of the support plate 12. The level 13 can help detect whether the detection device is in a horizontal state, which is crucial for detecting the balance of the bicycle handlebar.

[0028] Further, adjustment feet 14 are fixed at the lower end of the base 10 and located at the four corner ends. The adjustment feet 14 can ensure that the detection device remains stable under different ground conditions, avoiding detection errors caused by uneven ground. At the same time, by adjusting the feet 14 to ensure the level of the detection device, the accuracy of the detection results can be improved. Secondly, using the adjustment feet 14 on uneven ground can prevent the detection device from sliding or tipping over, improving the safety during use.

[0029] Further, the telescopic mechanism 20 includes a telescopic housing 21, a telescopic rod 22, and a handle 23. The telescopic housing 21 is fixed to the upper end of the U-shaped frame 11. The telescopic rod 22 is slidably connected to the inside of the telescopic housing 21. The handle 23 is threadedly connected to one end of the telescopic housing 21, and the handle 23 and the telescopic rod 22 are adapted to each other. The telescopic mechanism 20 allows the detection device to be adjusted according to the length and height of the bicycle handlebar, providing greater flexibility. The telescopic mechanism 20 enables the detection device to adapt to bicycles of different sizes, from children's bicycles to adult bicycles. By the telescopic mechanism 20, the distance between the detection device and the bicycle handlebar can be precisely adjusted to ensure the accuracy of the measurement.

[0030] The working principle of the present utility model is as follows:

[0031] During use, observe the level 13 to determine whether the detection device is parallel. When the detection device is not parallel, adjust the adjustment feet 14 to make the detection device parallel. When the detection device is parallel, place the wheel on the fixing mechanism 15. The height of the detection device can be adjusted by the telescopic mechanism 20. Rotate the handwheel 19. The rotation of the handwheel 19 drives the rotation of the threaded rod 18. The rotation of the threaded rod 18 drives the movement of the fixing block 17. When the fixing block 17 moves to fix the wheel with the fixing plate 16 and the handwheel 19 cannot be rotated, stop rotating the handwheel 19. At this time, move the two sliders 29 at both ends of the partition plate 27 to the same distance from the partition plate 27. By pushing the measuring plate 33 to the distance in contact with the bicycle handlebar, fix the measuring plate 33 with the fixing knob 34. Observe whether the readings of the second scale 35 on the two measuring plates 33 are the same. If they are the same, loosen the fixing knob 34 for the next measurement. If the readings of the second scale 35 at both ends are different, the bicycle handlebar is unbalanced.

[0032] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
