Description
Technical Field
[0001] This utility model belongs to the technical field of bicycle repair racks, and more specifically, it relates to a bicycle repair rack. Background Technology
[0002] Currently, bicycles are one of the most commonly used means of transportation. After prolonged use, some parts will inevitably be damaged. In order to facilitate repairs, repair personnel need to suspend the bicycle to a position suitable for their operation, thereby increasing repair efficiency. Currently, the common repair methods are to repair the bicycle upside down or to suspend it using a fixed repair rack. This is where this device is needed.
[0003] Based on existing technology, it has been found that existing bicycle repair racks cannot conveniently hold different types of bicycles. Furthermore, tools are typically placed on the rack, but if the rack obstructs the height during repairs, it must be disassembled and reinstalled, making operation inconvenient and affecting work efficiency. When repairing bicycles suspended in the air by the rack, the front and rear wheels can easily rotate, and the front wheel, which also has a steering function, requires manual control to limit wheel rotation, making the operation cumbersome and lacking appropriate limiting structures.

[0010] Furthermore, the shelf includes: a sliding plate;
[0011] The sliding plate is disposed inside the shelf; the sliding plate has a rectangular notch; the sliding plate is slidably connected to the partition on the shelf through the rectangular notch.
[0012] Furthermore, a support frame is provided on the support rod; the bottom of the support frame is provided with reinforcing ribs.
[0013] Furthermore, the support frame includes: a slide bar, a sliding member, a screw B, a connecting rod, and a limiting member;
[0014] The slide bar is fixedly installed on the top right side of the support frame; there are two sets of sliding components, and the sliding components are slidably installed on the slide bar; the front sliding component has a threaded hole, and a screw B is installed inside the threaded hole of the sliding component; the front sliding component has round holes on both sides, and a connecting rod is slidably installed inside the round hole on the front sliding component; the bottom of the sliding component is set with an arc-shaped structure; the limiting component is rotatably connected to the screw B; the limiting component is fixedly connected to the connecting rod.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This device includes an installation component and an adjustment component. By placing the bicycle frame on the bottom clamping component and holding and rotating the handle on the adjustment component, the installation component is rotated at a certain angle on the rotating component, thereby causing the top clamping component to contact the bicycle frame. This allows for the fixing of bicycle frames of different models. The clamping component has a V-shaped structure and an arc groove, which increases the friction when in contact with the bicycle frame, resulting in a more stable clamping effect.
[0017] 2. This device includes a screw A and a sliding plate. Screw A is rotatably mounted on the bottom of the main body, while the sliding plate is slidably mounted inside the shelf. This allows the shelf to rise and fall synchronously when the main body is adjusted in height. This ensures that the shelf does not need to be repeatedly disassembled and reassembled. Furthermore, by manually rotating screw A, the shelf can be moved on the support rod, allowing for convenient adjustment to a suitable height. This makes operation more convenient. At the same time, pushing the sliding plate can rationally divide the internal space of the shelf, preventing disassembled parts from mixing, improving the space utilization of the shelf, facilitating the retrieval of parts, and increasing work efficiency.
[0018] 3. In this device, a sliding component and a limiting component are provided. By pushing the sliding component, the sliding component corresponds to the wheel. By moving the support frame upward and fixing the support frame to the support rod with bolts, the front and rear wheels of the bicycle come into contact with the bottom of the sliding component, thereby restricting the rotation of the front and rear wheels and providing auxiliary support for the front and rear wheels. By rotating the two sets of screws B, the limiting component comes into contact with both sides of the front wheel, thereby fixing and clamping the front wheel to ensure the stability of the wheel during maintenance.

[0035] The specific usage and function of this embodiment are as follows:
[0036] In this invention, when using the device, the bicycle frame is placed on the bottom clamping member 304. By holding and rotating the handle on the adjusting member 303, the mounting member 301 rotates at a certain angle on the rotating member 3, thereby causing the top clamping member 304 to contact the bicycle crossbeam. This allows for the fixing of different models of bicycle crossbeams.

When the height of the main body 1 is adjusted, the storage rack 6 can rise and fall synchronously, ensuring that the storage rack 6 does not need to be repeatedly disassembled and reassembled. Furthermore, by manually rotating the screw A5, the storage rack 6 is moved on the support rod 4, thus allowing for convenient adjustment of the storage rack 6. The appropriate height makes operation more convenient. Simultaneously, pushing the sliding plate 601 allows for reasonable partitioning of the internal space of the rack 6, preventing the mixing of disassembled parts, improving the space utilization of the rack 6, facilitating parts retrieval, and increasing work efficiency. Pushing the sliding member 702 aligns it with the wheels, and by moving the support frame 7 upwards and fixing it to the support rod 4 with bolts, the front and rear wheels of the bicycle contact the bottom of the sliding member 702, thus restricting the rotation of the front and rear wheels and providing auxiliary support. Rotating the two sets of screws B703 causes the limiting member 705 to contact both sides of the front wheel, thus fixing and clamping the front wheel to ensure stability during maintenance. When the bicycle needs to be rotated, the support frame 7 is removed, and the rear rotating handle 2 and button 201 are operated to release the restriction on the rotating member 3, allowing the rotating member 3 to rotate the bicycle at any angle, facilitating maintenance work.
