Description

Technical Field

[0001] This application relates to the technical field of bicycles, and specifically to a bicycle frame. Background Art

[0002] A bicycle is a vehicle driven by human power. Riding a bicycle is not only green and environmentally friendly, but also can achieve a certain exercise effect. Among them, the frame is an important component of a bicycle. For the convenience of long-distance riding, some bicycles usually set up a water cup holder on the frame of the bicycle to place drinking water, so as to facilitate the provision of moisture, sugar or energy during the riding process.

[0003] The Chinese utility model patent with the publication number CN220884671U discloses a carbon fiber bicycle frame that can fix a water cup, including a frame body. A bracket is connected to the outer surface of the frame body, and a placement cylinder is connected inside the bracket. A handle penetrates through the outer surface of the placement cylinder, and a torsion spring is arranged between the handle and the placement cylinder. A limiting block is connected below the inner part of the frame body, and a limiting groove is opened above the outer surface of the bracket. The handle is rotatably connected to the placement cylinder, and the placement cylinder is rotatably connected to the bracket. Through the settings of the bracket, the placement cylinder, the handle, the torsion spring and the limiting groove, the surrounding of the water bottle is blocked by the cooperation of the placement cylinder and the bracket, thereby avoiding the phenomenon that the water temperature rises due to sunlight irradiating the water bottle. At the same time, because the thermal conductivity of plastic is relatively low, it can play a certain heat insulation effect and reduce the influence of the external temperature on the water bottle; effectively avoid direct sunlight on the water bottle and reduce the influence of the external temperature on the water bottle.

[0004] The device is provided with a frame body, and a bracket is connected to the frame body. A placement cylinder is connected inside the bracket. When placing a water cup, the rider pulls the placement cylinder through the handle, and then places the water cup in the placement cylinder and then pushes the placement cylinder. However, when the placement cylinder fits with the bracket, the bracket blocks the open end of the placement cylinder. When the height of the water cup exceeds the placement cylinder, it is inconvenient to push and fit the placement cylinder, and the scope of application is not high. Utility Model Content

One end of the first spring 5 is fixedly connected to the end cap 4, and the other end of the first spring 5 is fixedly connected to the storage cylinder 3. One end of the lever 6 is rotatably connected to the storage cylinder 3, and the clamping mechanism is provided on the storage cylinder 3.

[0025] In at least one embodiment, the clamping mechanism includes a clamping plate 7, a limiting rod 701 and a second spring 702. The clamping plate 7 is arranged at the top of the storage groove 301 and is arc-shaped. A limiting rod 701 is fixedly provided at the top of the clamping plate 7. Through holes adapted to the limiting rod 701 are provided on both the storage cylinder 3 and the sliding sleeve 2. A second spring 702 is sleeved on a section of the limiting rod 701 within the storage groove 301. Both ends of the second spring 702 are fixedly connected to the clamping plate 7 and the storage cylinder 3 respectively. When the water cup is slid and placed along the storage groove 301, the side wall of the water cup abuts against the clamping plate 7, thereby pushing the clamping plate 7 to rise and simultaneously compressing the second spring 702. The water cup is clamped by the second spring 702 and the arc-shaped clamping plate 7 to ensure the safe placement of the water cup.

[0026] In at least one embodiment, a guide rail is fixedly provided on the cross beam 101, and a chute 201 adapted to the guide rail is provided on the sliding sleeve 2. The sliding sleeve 2 is limited by setting the guide rail to prevent the sliding sleeve 2 from generating circumferential swing.

[0027] In at least one embodiment, a threaded hole is provided on the sliding sleeve 2, and an adjusting rod 202 is threadedly inserted into the threaded hole. One end of the adjusting rod 202 within the threaded hole abuts against the cross beam 101.

[0031] When performing the operation of placing a water cup on the vehicle frame, the rider can slide the sliding sleeve 2 along the cross beam 101, thereby driving the storage cylinder 3 to slide, so that the position of the storage cylinder 3 can be adjusted according to different taking ranges, and the operation is convenient. Then, the staff rotates the lever 6 at one end of the storage cylinder 3 to rotate it until it is disengaged from the overlapping with the storage groove 301. Then, the water cup can be aligned with the storage groove 301 and inserted therein. When the height of the water cup exceeds the length of the storage groove 301, one end of the water cup abuts against the end cap 4 when the water cup is placed in the storage groove 301. After that, when the water cup is continuously inserted, one end of the water cup drives the end cap 4 to slide outwards. When the end cap 4 slides, the insertion rod 401 on the end cap 4 slides along the counterbore 302 to realize the limiting of the end cap 4. And when the end cap 4 moves away from the storage cylinder 3, the first spring 5 will be stretched. After the water cup is completely placed in the storage groove 301, rotate the lever 6 at the other end of the storage cylinder 3 to make the lever 6 overlap with the storage groove 301 to realize the abutting limit of the water cup. Then, the clamping mechanism in the storage groove 301 can clamp the water cup to prevent the water cup from colliding with the storage cylinder 3 in the storage groove 301, ensuring storage safety. In this device, the slidable end cap 4 is used to place and store water cups of different specifications, improving the scope of application.
