Description

Technical Field

[0001] This utility model relates to the field of bicycle kickstand technology, and in particular to a bicycle kickstand. Background Technology

[0002] Bicycles, as a green, environmentally friendly, simple, and easy-to-operate means of transportation, are widely used in various fields such as daily travel, sports and fitness, and leisure and entertainment. In order to facilitate parking when not in use, bicycles are usually equipped with kickstands on the side crossbeams to support the body and keep it stable. Most existing bicycle kickstands adopt a rotating or folding structure, which is folded up when riding and unscrewed to support the ground when parking.

[0003] An existing bicycle kickstand (publication number: CN222329876U) has at least the following drawbacks: Although the above-mentioned device can adapt to bicycles of different heights by adjusting the length of the kickstand, in actual parking, the bicycle usually needs to maintain a certain tilt angle to prevent the vehicle from tipping over. Therefore, while adjusting the length of the kickstand, its tilt angle also needs to be adjusted accordingly. The device usually achieves the tilt angle adjustment by rotating the connection between the kickstand and the bicycle crossbeam. However, since the kickstand mounting holes usually need to be precisely matched with the shape of the crossbeam and installed correctly, excessive rotation may lead to insecure installation, affecting structural stability, thus resulting in poor device performance. Therefore, we propose this utility model. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bicycle kickstand.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bicycle kickstand includes two arc plates mounted on a bicycle crossbeam. A mounting base is fixed to the bottom surface of the outer arc plate. A support rod is disposed below the mounting base, and an extension rod is disposed inside the support rod. An adjustment structure for adjusting the inclination of the support rod is disposed below the mounting base. The adjustment structure includes a mounting post disposed below the mounting base. A mounting notch is formed on the bottom surface of the mounting post. A worm gear is rotatably disposed inside the mounting notch. A worm is rotatably disposed inside the mounting post. The worm gear meshes with the worm gear. One end of the worm passes through the interior of the mounting post and is fixed with a handwheel. A connecting rod is fixed between the worm gear and the support rod.

[0007] As a further embodiment of this utility model, the outer circular wall of the mounting base is provided with two limiting grooves, the included angle between the two limiting grooves is degrees, the outer circular wall of the mounting base is provided with a movable plate, the movable plate is U-shaped, the movable plate rotates around the circumference of the mounting base, the bottom surface of the movable plate is connected to and fixed with a fixed cylinder, the inside of the fixed cylinder is provided with a first spring, the top end of the first spring abuts against a ball, the bottom end of the fixed cylinder is fixed to the top end of the mounting column, and the ball is slidably inserted into the corresponding limiting groove.

[0008] As a further embodiment of this utility model, the extension rod and the support rod are slidably inserted inside each other. The support rod has several snap-fit ​​holes on one side, which are evenly distributed along the length of the support rod. The outer circular wall of the extension rod is slidably inserted with a shaft, and a second spring is fixed between the shaft and the inside of the extension rod.

[0009] As a further embodiment of this utility model, the two arc plates are fixed together by bolts, and the bicycle crossbeam is located between the two arc plates.

[0010] As a further embodiment of this invention, a gasket is provided between the two arc plates and the bicycle crossbeam.

[0011] As a further embodiment of this utility model, two limiting plates are fixed to the outer circular wall surface of the mounting base.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This bicycle kickstand, through its adjustable structure, allows operators to rotate a worm gear via a handwheel, which in turn drives a worm wheel to rotate a support rod and an extension rod around the center of the worm wheel, thus adjusting the kickstand's tilt angle. Users can also kick the support rod to rotate a movable plate around the mounting base, switching between horizontal and vertical directions. When the support rod is in the corresponding position, the ball bearings automatically engage with the limit groove under spring action, achieving a limit lock and facilitating the unfolding and folding of the kickstand. This not only makes it convenient for users to adjust the kickstand's tilt angle but also avoids interference with the kickstand and bicycle mounting positions, further enhancing the kickstand's ease of use and stability.

[0023] Reference Figures 1-5A bicycle kickstand includes two arc plates 2 mounted on a bicycle crossbeam 1. A mounting base 3 is fixed to the bottom surface of the outer arc plate 2. A support rod 4 is provided below the mounting base 3. An extension rod 5 is provided inside the support rod 4. An adjustment structure for adjusting the inclination of the support rod 4 is provided below the mounting base 3. The adjustment structure includes a mounting post 201 provided below the mounting base 3. A mounting notch 202 is opened on the bottom surface of the mounting post 201. A worm gear 203 is rotatably mounted inside the mounting notch 202. A worm 204 is rotatably mounted inside the mounting post 201. The worm gear 203 meshes with the worm 204. One end of the worm 204 passes through the interior of the mounting post 201 and is fixed with a handwheel. A connecting rod 205 is fixed between the worm gear 203 and the support rod 4.

[0024] In this embodiment, the outer circular wall of the mounting base 3 has two limiting grooves 301, and the included angle between the two limiting grooves 301 is 90 degrees. A movable plate 302 is provided on the outer circular wall of the mounting base 3. The movable plate 302 is U-shaped and rotates around the circumference of the mounting base 3. A fixed cylinder 303 is fixedly connected to the bottom surface of the movable plate 302. A first spring 304 is provided inside the fixed cylinder 303, and a ball bearing 305 abuts against the top of the first spring 304. The bottom end of the fixed cylinder 303 is fixed to the top end of the mounting post 201. The ball bearing 305 is slidably inserted into the corresponding limiting groove 301. By adjusting the structure, the operator can rotate the worm gear 204 via a handwheel. The worm gear 204 drives the worm wheel 203 to rotate. The rotation of the worm wheel 203 further drives the support rod 4 and the extension rod 5 to rotate around the worm wheel 203. The center of 03 rotates to adjust the tripod support angle. The worm gear 203 and worm 204 have a self-locking function, so the adjusted angle will not easily change. At the same time, when using the tripod, the user can push the support rod 4 by kicking it, so that the movable plate 302 rotates around the circumference of the mounting base 3, realizing the switching between the horizontal and vertical directions of the support rod 4. When the support rod 4 is in the horizontal or vertical position, under the action of the first spring 304, the ball 305 will automatically spring into the corresponding limit groove 301 to limit the position of the support rod 4, effectively realizing the unfolding and folding operation of the tripod. The above structure not only makes it convenient for the user to adjust the tilt angle of the tripod, but also avoids interference with the installation position of the tripod and the bicycle, further improving the ease of use and stability of the tripod.

[0025] In this embodiment, the extension rod 5 and the support rod 4 are slidably inserted inside each other. The support rod 4 has several locking holes 401 on one side, which are evenly distributed along the length of the support rod 4. The outer circular wall of the extension rod 5 is slidably inserted with a shaft 402. A second spring 403 is fixed between the shaft 402 and the extension rod 5. When the user needs to adjust the length of the tripod, he can press the shaft 402 to compress the second spring 403, and the shaft 402 will retract into the extension rod 5. Then, the extension rod 5 can be slid to adjust the overall length of the extension rod 5 and the support rod 4. After adjustment, the shaft 402 is inserted into the corresponding locking hole 401 under the action of the second spring 403 to limit the extension rod 5 and the support rod 4, thereby realizing the adjustment of the tripod support length and improving the adaptability of the device.

[0026] In this embodiment, the two arc plates 2 are fixed together by bolts, and the bicycle crossbeam 1 is located between the two arc plates 2. The two arc plates 2 make it easy for the user to install and fix the kickstand to the bicycle.

[0027] In this embodiment, a shim 501 is provided between the two arc plates 2 and the bicycle crossbeam 1. The shim 501 is made of rubber. The shim 501 can increase the friction between the bicycle crossbeam 1 and the arc plates 2, prevent the footrest from deflecting, improve the installation stability, and at the same time prevent the bicycle crossbeam 1 from deforming due to excessive tightening of the bolts.

[0028] In this embodiment, two limiting plates 6 are fixed on the outer circular wall of the mounting base 3. The two limiting plates 6 can prevent the user from excessively rotating the movable plate 302, causing the ball 305 to misalign with the limiting groove 301.

[0029] Working Principle: During use, the operator can rotate the worm gear 204 via the handwheel. The worm gear 204 drives the worm wheel 203 to rotate, which in turn drives the support rod 4 and extension rod 5 to rotate around the center of the worm wheel 203, thereby adjusting the tripod support angle. The worm wheel 203 and worm gear 204 have a self-locking function, preventing the adjusted angle from easily changing. Simultaneously, when using the tripod, the user can push the support rod 4 by kicking it, causing the movable plate 302 to rotate circumferentially along the mounting base 3, switching the support rod 4 between horizontal and vertical directions. When the support rod 4 is in a horizontal or vertical position, under the action of the first spring 304, the ball bearing 305 automatically springs into the corresponding limiting groove 301, limiting the position of the support rod 4 and effectively enabling the tripod to be extended and retracted. This structure not only facilitates the user in adjusting the tripod's tilt angle but also avoids damage to the tripod and its surroundings. The interference of the bicycle installation position further improves the ease of use and stability of the kickstand. When the user needs to adjust the length of the kickstand, they can press the insert shaft 402 to compress the second spring 403, and the insert shaft 402 will retract into the extension rod 5. Then, slide the extension rod 5 to adjust the overall length of the extension rod 5 and the support rod 4. After adjustment, the insert shaft 402, under the action of the second spring 403, inserts into the corresponding snap hole 401 to limit the extension rod 5 and the support rod 4, thereby realizing the adjustment of the kickstand support length and improving the adaptability of the device. The two arc plates 2 make it easy for the user to install and fix the kickstand to the bicycle. The shim 501 can increase the friction between the bicycle crossbeam 1 and the arc plate 2 to prevent the kickstand from deflecting and improve the installation stability. At the same time, it can prevent the bicycle crossbeam 1 from deforming due to excessive tightening of the bolts. The two limiting plates 6 can prevent the user from excessively rotating the movable plate 302 and causing the ball 305 to misalign with the limiting groove 301.
