Description

Technical Field

[0001] This application relates to the field of repair equipment technology, specifically a bicycle wheel straightening device. Background Technology

[0002] A bicycle, also known as a pedal bike or cyclist, is typically a small, two-wheeled land vehicle. Riders power it by pedaling, making it a green and environmentally friendly mode of transportation. There are many types of bicycles, including single-person, tandem, and multi-person bicycles. They can be used for commuting and getting around in an environmentally friendly way; increasingly, people are using bicycles as fitness equipment for exercise and cycling tours; and cycling itself is also a competitive sport, with events such as road cycling, mountain biking, track cycling, and stunt cycling.

[0003] Over time, bicycles may develop wheel wobble, often caused by tire out-of-roundness. Common causes include tire wear, rim damage, and loose spokes. Tire wear and rim damage are usually due to wear or impact, and to ensure driving safety and structural stability, it is generally recommended to replace the tires and rims. However, wheel out-of-roundness caused by loose spokes can be corrected through repair. Currently, there is a lack of specialized equipment for spoke correction, and it is typically judged by visual inspection of the wheel's centerline, which introduces errors and results in unsatisfactory calibration.

[0004] Therefore, this application provides a bicycle wheel straightening device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a bicycle wheel straightening device, which aims to solve the problems mentioned in the background art, such as the poor accuracy of existing visual calibration.

[0006] To achieve the above objectives, this application provides the following technical solution: a bicycle wheel straightening device, comprising a support and a laser calibrator mounted on the support. The central axis of the support is on the same plane as the ray direction of the laser calibrator; The support includes a base, on which a column is fixedly mounted. The column has a mounting groove and a through-hole rotating cavity. A support arm is rotatably mounted on the base, and the laser calibrator is rotatably mounted on the support arm. In use, the base is placed on a level surface, the wheel is placed in the rotating cavity, and the wheel axle is placed in the mounting groove to secure the wheel. Then, the laser calibrator is rotated to its highest point using the support arm, and turned on. The laser beam is then directed onto the tire tread. The alignment between the tire tread centerline and the laser beam is observed, and the spokes are adjusted accordingly. Compared to directly observing the tire tread with the naked eye, the laser beam alignment is more precise, resulting in better calibration.

[0007] Preferably, in order to support the wheels, the base and the column are designed in an inverted T shape, and the mounting groove is opened on the end of the column away from the base. The mounting groove is set through the end of the column. The base with a larger cross-sectional area can provide more stable support for the column when in contact with the ground.

[0008] Preferably, in order to ensure the wheel is installed in the correct position, the column is designed to be divided into two parts in the middle of the rotating cavity along the ray direction of the laser calibrator, and the two columns are symmetrically distributed to ensure accurate alignment of the laser calibrator's ray.

[0009] Preferably, to prevent slippage, anti-slip pads are fixedly installed at the four corners of the bottom of the base, and the four anti-slip pads are designed to be at the same horizontal height to prevent slippage and shaking when the wheels are turned.

[0010] Preferably, for storage purposes, the base has a storage cavity designed to communicate with the rotating cavity, and the support arm is rotatably installed in the storage cavity, so that the support arm can be rotated into the storage cavity for storage, making it convenient to store.

[0011] Preferably, in order to adjust the irradiation range, the support arm includes a rotating rod rotatably mounted at one end inside the storage cavity. A knob that fits against the outer wall of the base is screwed onto the rotating rod. A first support rod is fixedly mounted on the rotating rod. A second support rod is hinged to the end of the first support rod away from the rotating rod. The laser calibrator is rotatably mounted on the end of the second support rod away from the first support rod, thereby adjusting the position of the laser calibrator to accommodate wheels of different diameters.

[0012] This wheel alignment device places the base on a level surface, places the wheel in the rotating cavity, and places the wheel axle in the mounting slot to fix the wheel. Then, the laser calibrator is rotated to the highest point by the support arm, and the laser calibrator is turned on. The laser beam of the calibrator shines on the tire tread, and the degree of overlap between the center line of the tire tread and the laser beam of the calibrator is observed. The spokes are then adjusted. Compared with direct observation of the tire tread with the naked eye, the alignment accuracy of the laser beam is higher, and the calibration effect is better.

[0013] When the support arm needs to be stored, this rounding device can rotate the support arm into the storage cavity for easy storage. Attached Figure Description

[0016] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Example 1

[0017] This embodiment provides a bicycle wheel straightening device, such as... Figures 1-3 As shown, the roundness straightening device includes a support 1 and a laser calibrator 2 mounted on the support 1. The central axis of support 1 and the ray direction of laser calibrator 2 are on the same plane; The support 1 includes a base 11, a column 12 is fixedly installed on the base 11, the column 12 has an installation groove 13 and a through-hole rotating cavity 14, and a support arm 21 is rotatably installed on the base 11. The laser calibrator 2 is rotatably installed on the support arm 21.

[0018] In use, place the base 11 on a horizontal surface, place the wheel in the rotating cavity 14, and place the wheel axle in the mounting groove 13 to fix the wheel. Then, rotate the laser calibrator 2 to the highest point using the support arm 21, turn on the laser calibrator 2, and let the laser beam of the laser calibrator 2 shine on the tire surface of the wheel. Observe the degree of overlap between the center line of the tire surface and the laser beam of the laser calibrator 2, and then adjust the spokes. Compared with directly observing the tire surface with the naked eye, the alignment accuracy of the laser beam is higher, and the calibration effect is better.

[0019] Specifically, the base 11 and the column 12 are in an inverted T-shape design, and the mounting groove 13 is opened on the end of the column 12 away from the base 11. The mounting groove 13 is set through the end of the column 12.

[0020] In use, the wheel is inserted into the rotating cavity 14 from the top of the column 12, and the wheel axle is inserted into the mounting groove 13 from the top of the column 12. The installation is convenient and quick. The base 11 with a larger cross-sectional area can provide more stable support for the column 12 when in contact with the ground.

[0021] More specifically, the column 12 is designed to be divided into two parts by the rotating cavity 14 in the direction of the laser calibrator 2, and the two columns 12 are symmetrically distributed.

[0022] When in use, after installing the wheel in the rotating cavity 14, ensure that the wheel is in the exact middle position of the two columns 12 to ensure that the laser calibrator 2 is accurately aligned.

[0023] Furthermore, anti-slip pads 15 are fixedly installed at the four corners of the bottom of the base 11, and the four anti-slip pads 15 are designed to be at the same horizontal height.

[0024] When in use, place the base 11 on a horizontal surface, with the anti-slip pad 15 in contact with the ground, so that the base 11 is stable after being placed, and avoids slippage and shaking when the wheels are turned. Example 2

[0025] Unlike Embodiment 1, the extended support arm 21 occupies too much space when not in use and is inconvenient to store. Therefore, the base 11 is provided with a storage cavity 22 that is connected to the rotating cavity 14, and the support arm 21 is rotatably installed in the storage cavity 22.

[0026] When in use, the support arm 21 can be rotated into the storage cavity 22 for easy storage when it needs to be stored.

[0027] Furthermore, the support arm 21 includes a rotating rod 211 rotatably mounted at one end inside the storage cavity 22. A knob 212 that fits against the outer wall of the base 11 is screwed onto the rotating rod 211. A first support rod 213 is fixedly mounted on the rotating rod 211. A second support rod 214 is hinged to the end of the first support rod 213 away from the rotating rod 211. The laser calibrator 2 is rotatably mounted on the end of the second support rod 214 away from the first support rod 213.

[0028] In use, rotate the first support rod 213 around the pivot rod 211 to remove the first support rod 213 from the storage cavity 22. Then pull the second support rod 214 and rotate the second support rod 214 around the hinge point between the second support rod 214 and the first support rod 213 to adjust the position of the laser calibrator 2 so as to adapt to wheels of different diameters and improve the applicability of the equipment. After use, fold the first support rod 213 and the second support rod 214, and then fold the first support rod 213 into the storage cavity 22 for storage, which is convenient for transportation and storage.

[0029] It should be noted that after rotating the first support rod 213, the first support rod 213 can be fixed by friction between the side wall of the knob 212 and the side wall of the base 11 by rotating the knob 212, thus completing the positioning of the first support rod 213. The hinge joint between the second support rod 214 and the first support rod 213 is also fixed by friction, so that the second support rod 214 will not easily rotate after rotation.

[0030] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
