[0013] Compared with the prior art, the present invention provides an auxiliary ramp installation structure for bicycle frames, which has the following advantages: The auxiliary ramp installation structure of this bicycle frame features equidistant insertion holes on the surface of the hinge rod near its top. A sliding sleeve can slide up and down on the hinge rod. By cranking the handle, the screw moves the insertion rod back and forth, allowing the insertion rod to connect with holes of different heights, thus flexibly adjusting the height of the fixing rod and the first buckle. This design meets the installation needs of bicycle frames of different sizes, enhancing the versatility and adaptability of the structure.

[0019] This utility model provides the following technical solution: Example 1

[0020] Please see Figure 1-4 This utility model provides a technical solution: an auxiliary ramp installation structure for a bicycle frame, including a frame 1, an installation mechanism 2 provided on the surface of the frame 1, and a storage limiting mechanism 3 provided on the right side of the front of the frame 1; The mounting mechanism 2 includes a fixing component 21, which is fixedly connected to the surface of the frame 1.

A sliding sleeve 24 is slidably connected to the surface of the hinge rod 23 near the top. A fixing rod 25 is fixedly connected to the surface of the sliding sleeve 24. A first buckle 26 is fixedly connected to the rear end of the fixing rod 25. A fixing frame 27 is fixedly connected to the surface of the sliding sleeve 24. An internally threaded cylinder 28 is provided on the front of the fixing frame 27. A screw 29 is internally threaded to the internally threaded cylinder 28. A crank handle 211 is fixedly connected to the front end of the screw 29. An insertion rod 212 is fixedly connected to the rear end of the screw 29. Insertion holes 213 are equidistantly opened on the surface of the hinge rod 23 near the top. Arc grooves 214 are opened on the left and right sides of the top of the frame 1. A second buckle 215 is fixedly connected to the left and right sides of the bottom of the frame 1.

[0021] The front of the fixing bracket 27 has a hole that matches the outer wall of the internal threaded cylinder 28, and the outer wall of the internal threaded cylinder 28 passes through and is fixedly connected to the hole.

[0022] The sliding sleeve 24 has a hole on its surface that matches the insertion rod 212, and the insertion rod 212 passes through the surface and slides back and forth in the hole.

[0023] The insertion rod 212 is inserted into the insertion hole 213, the first buckle 26 secures the bicycle frame, and the two second buckles 215 secure the bicycle tires. Example 2

[0024] Please see Figure 5 Furthermore, based on Embodiment 1, a storage limiting mechanism 3 is obtained.

[0025] The storage limiting mechanism 3 includes an L-plate 31, which is fixedly connected to the right side of the front of the frame 1. A first arc-shaped rubber clamp 32 is fixedly connected to the bottom of the L-plate 31. A rectangular groove 33 is opened on the top of the L-plate 31. A rotating shaft 34 is rotatably connected to the left and right sides of the rectangular groove 33. A rotating plate 35 is fixedly connected to the surface of the rotating shaft 34. A second arc-shaped rubber clamp 36 corresponding to the first arc-shaped rubber clamp 32 is fixedly connected to the oblique back of the plate. A torsion spring 37 is sleeved on the surface of the rotating shaft 34.

[0026] One end of the torsion spring 37 is fixedly connected to the surface of the rotating plate 35, and the other end of the torsion spring 37 is fixedly connected to the bottom left side of the rectangular groove 33.

[0027] The hinge rod 23 is rotated 90 degrees and located inside the first arc-shaped rubber clamp 32 and the second arc-shaped rubber clamp 36.

[0028] In actual operation, when this device is in use, in its initial state, the hinge rod 23 is hinged to the fixing member 21 via the hinge frame 22, and is in a retractable or easily operable position. When a bicycle frame needs to be installed, the hinge rod 23 is rotated upward around the hinge frame 22 to a suitable working angle for installing the bicycle frame. The surface of the hinge rod 23 has equidistant insertion holes 213 near the top. The sliding sleeve 24 is fitted onto the hinge rod 23 and can slide up and down. Depending on the specifications of the bicycle frame and installation requirements, the sliding sleeve 24 is moved up and down to a suitable height. At this time, cranking the handle 211 causes the screw 29 to rotate and move back and forth within the internal threaded cylinder 28, as the handle 211 is fixedly connected to the front end of the screw 29, which is threaded into the internal threaded cylinder 28. A plug rod 212 is fixedly connected to the rear end of the screw 29. A hole matching the plug rod 212 is formed on the surface of the sliding sleeve 24. As the screw 29 moves backward, the plug rod 212 passes through the hole on the sliding sleeve 24 and inserts into the corresponding height-aligned plug hole 213 on the hinge rod 23, thereby fixing the sliding sleeve 24 at a specific height position on the hinge rod 23. A fixing rod 25 is fixedly connected to the surface of the sliding sleeve 24, and a first buckle 26 is fixedly connected to the rear end of the fixing rod 25. After the height of the sliding sleeve 24 is adjusted, the bicycle frame is placed in a suitable position, causing the first buckle 26 to engage with the corresponding part of the bicycle frame, thus achieving initial fixation of the bicycle frame. Meanwhile, the bottom left and right sides of the frame 1 are fixedly connected with second buckles 215. The bicycle tire is placed between the two second buckles 215 and fixed by the second buckles 215, which further enhances the stability of the bicycle during the installation process and prevents it from shaking or shifting. The top left and right sides of the frame 1 are provided with arc-shaped grooves 214. During the installation of the bicycle frame, the arc-shaped grooves 214 can play a certain guiding and auxiliary support role, so that the bicycle frame can be installed in the designated position more smoothly. At the same time, it also provides certain guidance and support for the movement of the bicycle on the auxiliary slope. After the bicycle frame is installed and used, when the hinge rod 23 needs to be stored, first remove the bicycle frame and tire from the first clip 26 and the second clip 215. Then, rotate the hinge rod 23 downwards by ninety degrees around the hinge frame 22, and fix the L plate 31 of the storage limiting mechanism 3 to the right side of the front of the frame 1. The bottom of the L plate 31 is fixedly connected to the first arc-shaped rubber clamp 32. The top of the L plate 31 has a rectangular groove 33, and the left and right sides of the rectangular groove 33 are rotatably connected to the rotating shaft 34. The surface of the rotating shaft 34 is fixedly connected to the rotating plate 35, and the back of the rotating plate 35 is fixedly connected to the second arc-shaped rubber clamp 36 corresponding to the first arc-shaped rubber clamp 32. The surface of the rotating shaft 34 is fitted with a torsion spring 37, one end of the torsion spring 37 is fixedly connected to the surface of the rotating plate 35, and the other end is fixedly connected to the bottom left side of the rectangular groove 33. When the hinge rod 23 flips downwards and approaches the L-plate 31, it presses against the rotating plate 35, causing the rotating plate 35 to rotate around the pivot 34. At the same time, the torsion spring 37 is twisted, generating elastic force. When the hinge rod 23 is fully inserted between the first arc-shaped rubber clamp 32 and the second arc-shaped rubber clamp 36, the rotating plate 35 automatically returns to its original position under the elastic force of the torsion spring 37, tightly clamping the hinge rod 23 between the first arc-shaped rubber clamp 32 and the second arc-shaped rubber clamp 36. This achieves the storage and fixation of the hinge rod 23, preventing it from shaking randomly or occupying too much space when not in use.
