Description

Technical Field

[0001] This utility model relates to the field of bicycle support frame technology, specifically a bicycle support frame. Background Technology

[0002] A bicycle parking rack is a device used to secure and park bicycles. It is usually made of materials such as metal. Its main function is to fix the bicycle wheels in place through a specific design to prevent the bicycle from tipping over or sliding, thereby achieving orderly parking. It is widely used in public places, bicycle storage areas, and home yards. It not only regulates bicycle parking order and saves parking space, but also plays a role in protecting bicycles to a certain extent. It is an important part of urban transportation infrastructure and bicycle management.

[0003] Existing bicycle racks generally suffer from poor compatibility in their design. Most racks use a uniform size for the mounting brackets, which can only fit common standard wheels. However, bicycles come in various types and wheel sizes. When faced with non-standard wheels, such as larger tires, these single-size racks simply cannot fit the tires. If the tires are smaller, the fit between the bracket and the wheel is insufficient, resulting in an unstable bicycle that can easily slip off the rack with slight external force, causing damage to the bicycle. To address this, we propose a bicycle support frame. Utility Model Content

[0004] The purpose of this invention is to provide a bicycle support frame to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bicycle support frame, including a base, a limiting plate A fixedly connected to the surface of the base, two rectangular tubes fixedly connected to the surface of the base, pins slidably passing through the surface of the rectangular tubes, rectangular rods inserted into the inner walls of the rectangular tubes, and several circular holes opened on the surface of the rectangular rods, the size of the pins matching the size of the circular holes, a top plate fixedly connected to the end of the two rectangular rods away from the base, and a limiting plate B fixedly connected to the side of the top plate near the base.

[0006] The effect achieved by the above components is that this bicycle support frame adapts to different wheel sizes through the height-adjustable rectangular plate B, achieving stable clamping and expanding the range of applications for bicycles.

[0007] Preferably, a spring is fitted onto the surface of the rectangular rod, and the two ends of the spring are fixedly connected to the top plate and the rectangular tube, respectively.

[0008] The effect achieved by the above components is that the movement of the top plate will stretch the spring, which will prevent the pin from being pulled out of the round hole and the top plate from falling down and impacting the object, thereby preventing the rectangular rod from colliding and being damaged inside the rectangular tube.

[0009] Preferably, one end of the pin is fixedly connected to a rope, and the other end of the rope is fixedly connected to a rectangular tube.

[0010] The effect achieved by the above components is that one end of the pin is fixedly connected to the rectangular tube by a rope, preventing the pin from being lost or falling off during the adjustment process.

[0011] Preferably, a tie rod is fixedly connected to the surface of the top plate, and the vertical cross-section of the tie rod is U-shaped.

[0012] The effect achieved by the above components is that the movement of the pull rod will cause the top plate to move, and the pull rod makes it easier to pull the top plate.

[0013] Preferably, the inner walls of both the limiting plate A and the limiting plate B are fixedly connected to limiting blocks, and the limiting blocks are made of rubber.

[0014] The effect achieved by the above components is as follows: the rubber limiting block increases the contact area through friction, preventing the wheel from swaying left and right within the limiting plate A and the limiting plate B, and further adapting to the function of tires of different widths.

[0015] Preferably, an extension arm is fixedly connected to one side of the base, and a rectangular plate is fixedly connected to the end of the extension arm away from the base.

[0016] The effect achieved by the above components is that the bicycle will be pushed into the limiting plate A by the rectangular plate, and the rectangular plate facilitates the pushing of the bicycle wheels into the limiting plate A.

[0017] Preferably, a plurality of anti-slip strips are fixedly connected to the surface of the rectangular plate.

[0018] The effect achieved by the above components is that the anti-slip strips on the surface of the rectangular plate increase the friction between the wheel and the rectangular plate, thereby making it easier to push the bicycle wheel into the limiting plate A.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model features a rectangular rod that can slide up and down inside a rectangular tube. By engaging with round holes at different positions via a pin, the distance between limiting plates A and B can be flexibly adjusted. This adapts to bicycle wheels of different sizes, such as those for children's bikes, mountain bikes, and road bikes, avoiding the problem of "large wheels not fitting and small wheels not being securely fastened" caused by the single size of the fixing slots in traditional brackets, thus expanding the scope of application.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2 This utility model provides a technical solution: a bicycle support frame, including a base 1, a limiting plate A2 fixedly connected to the surface of the base 1, two rectangular tubes 3 fixedly connected to the surface of the base 1, pins 4 slidingly passing through the surface of the rectangular tubes 3, rectangular rods 5 inserted into the inner wall of the rectangular tubes 3, and several round holes 6 opened on the surface of the rectangular rods 5. The size of the pins 4 is adapted to the size of the round holes 6. A top plate 7 is fixedly connected to the end of the two rectangular rods 5 away from the base 1, and a limiting plate B8 is fixedly connected to the side of the top plate 7 close to the base 1. This bicycle support frame adapts to different wheel sizes through the height-adjustable rectangular plate 14B, achieving stable clamping and expanding the applicable range of bicycles.

[0029] Reference Figure 3 and Figure 4 and Figure 5As shown in this embodiment: A spring 9 is fitted onto the surface of the rectangular rod 5. Both ends of the spring 9 are fixedly connected to the top plate 7 and the rectangular tube 3, respectively. Movement of the top plate 7 stretches the spring 9, preventing the pin 4 from being pulled out of the round hole 6 and falling rapidly into the top plate 7, thus avoiding damage to the rectangular rod 5 within the rectangular tube 3. A rope 10 is fixedly connected to one end of the pin 4, and the other end of the rope 10 is fixedly connected to the rectangular tube 3. The connection between the pin 4 and the rectangular tube 3 via the rope 10 prevents the pin 4 from being lost or falling off during adjustment. A pull rod 11 is fixedly connected to the surface of the top plate 7. The vertical cross-section of the pull rod 11 is U-shaped. Movement of the pull rod 11 moves the top plate 7, facilitating the pulling of the top plate 7. Limiting blocks 12, made of rubber, are fixedly connected to the inner walls of both limiting plates A2 and B8. The rubber blocks increase the contact area through friction, preventing the wheel from swaying left and right within the limiting plates A2 and B8, and further accommodating tires of different widths. An extension arm 13 is fixedly connected to one side of the base 1. A rectangular plate 14 is fixedly connected to the end of the extension arm 13 away from the base 1. The bicycle is pushed into the limiting plate A2 using the rectangular plate 14, which facilitates pushing the bicycle wheel into the limiting plate A2. Several anti-slip strips 15 are fixedly connected to the surface of the rectangular plate 14. These anti-slip strips 15 increase the friction between the wheel and the rectangular plate 14, further facilitating pushing the bicycle wheel into the limiting plate A2.

[0030] Working principle: Pulling out pin 4 causes it to slide within rectangular tube 3 and gradually disengage from the round hole 6. After disengagement, one end of pin 4 is fixedly connected to rectangular tube 3 via rope 10 to prevent loss or detachment during adjustment. Pulling lever 11 moves top plate 7, which in turn moves rectangular rod 5 upwards, changing the length of rod 5 extending beyond rectangular tube 3, thus adjusting the distance between top plate 7 and base 1. The movement of top plate 7 stretches spring 9, preventing pin 4 from falling rapidly and impacting the top plate 7 after being pulled out of round hole 6, thus preventing damage to rectangular rod 5 within rectangular tube 3. The movement of top plate 7 also moves limiting plate B8, adjusting the distance between it and limiting plate A2. Once top plate 7 reaches the appropriate position... When the bicycle is pushed, it is pushed into the limiting plate A2 by the rectangular plate 14. The rectangular plate 14 facilitates the pushing of the bicycle wheel into the limiting plate A2. The anti-slip strips 15 on the surface of the rectangular plate 14 increase the friction between the wheel and the rectangular plate 14, thus further facilitating the pushing of the bicycle wheel into the limiting plate A2. Then, the limiting plate B8 is pulled towards the base 1 until the limiting plate B8 causes the limiting block 12 to press against the surface of the bicycle wheel. Then, the pin 4 is inserted into the corresponding round hole 6. The engagement of the pin 4 and the round hole 6 locks the position of the rectangular rod 5, so that the limiting plate A2 and the limiting plate B8 form a stable clamping space to accommodate bicycle wheels of different sizes. The rubber limiting block 12 increases the contact area through friction, preventing the wheel from wobbling left and right within the limiting plate A2 and the limiting plate B8, further accommodating tires of different widths.
