Description

Technical Field

[0001] This utility model relates to the field of motorcycle frame technology, and in particular to an adjustable support device for a motorcycle bracket. Background Technology

[0002] Motorcycles are a flexible and convenient means of transportation, and they are popular all over the world. Whether it is urban commuting, leisure riding or competitive events, they can be seen everywhere. In the daily use, maintenance and repair of motorcycles, the motorcycle stand plays an indispensable role. When it is necessary to inspect or repair the motorcycle's tires, chain, brake system and other parts, using the motorcycle stand to lift the motorcycle can create a more convenient operating space for maintenance personnel and greatly improve work efficiency.

[0003] In the existing technology, although the existing motorcycle lifter can lift the motorcycle, the distance between the two sides of the top of the lifter needs to be adjusted before use, depending on the motorcycle. The existing adjustment method is to tighten or loosen the adjustment rod by tightening or loosening the knob. However, when tightening the knob, it is easy to loosen during use because it is manually tightened, which can cause the motorcycle to tip over. Therefore, an adjustable support device for motorcycle brackets has been designed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable support device for motorcycle brackets.

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

[0006] An adjustable support device for a motorcycle bracket includes a U-shaped frame with diagonal braces fixedly connected to both ends. Hollow square tubes are fixedly connected to the tops of the two diagonal braces. Each hollow square tube has an adjustment mechanism, comprising a rotating rod that rotatably passes through both sides of the middle of the hollow square tube. Circular holes adapted to the rotating rod are provided on both sides of the hollow square tube. A handwheel is fixedly connected to one end of the rotating rod, and a limiting post is fixedly connected to the other end. Multiple limiting grooves are provided on the surface of the limiting post. A gear is fixedly fitted onto the rotating rod at the middle of the inner side of the hollow square tube. A first fixing ring is fixedly connected to the end of the rotating rod near the handwheel, and a first spring is fitted onto the side of the rotating rod near the first fixing ring and the hollow square tube. A sliding collar is fitted onto the rotating rod between the hollow square tube and the first spring. A second fixing ring is fixedly fitted onto the side of the rotating rod near the handwheel and the inner side of the hollow square tube. The adjustment mechanism facilitates adjustment of the distance between the two square rods, improving work efficiency.

[0007] Preferably, square rods are slidably sleeved on the inner sides of both hollow square tubes, and grooves are opened at the ends of the two square rods that are far apart from each other. A rack is fixedly connected to the middle of the bottom of each groove, and the rack meshes with a gear.

[0008] Preferably, a first support member is fixedly connected to one end of each of the two square rods that are close to each other, and a second support member is fixedly connected to the bottom of each of the two first support members. By setting the first support member and the second support member, the user can switch the required support member in real time according to his or her own needs.

[0009] Preferably, a rubber anti-slip sleeve is fixedly fitted in the middle of the U-shaped frame, and fixing members are fixedly fitted at both ends of the U-shaped frame, with rollers provided at the bottom of both fixing members.

[0010] Preferably, a limiting mechanism is provided on the outer side of both hollow square tubes near the limiting post. The limiting mechanism includes a fixed plate fixedly connected to the outer side of the hollow square tube. Vertical rods are fixedly connected to both ends of the top of the fixed plate. The same limiting plate is slidably sleeved on the circumferential surface of the two vertical rods. Circular holes adapted to the vertical rods are opened at both ends of the limiting plate. A protrusion is provided in the middle of the top of the limiting plate, and the protrusion is adapted to the limiting groove of the limiting post.

[0011] Preferably, the limiting mechanism further includes a limiting block fixedly connected to the top of the two vertical rods. A second spring is sleeved on each of the two vertical rods at the bottom of the limiting plate. A Z-shaped rod is fixedly connected to one end of the limiting plate. By setting the limiting mechanism, the handwheel cannot rotate when the Z-shaped rod is not pressed, and thus the position of the square rod cannot be adjusted, avoiding the motorcycle from falling over due to the change in the position of the square rod during operation.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By employing a square rod, a first support component, an adjustment mechanism, and a second support component, the square rod can be moved quickly and easily by turning a handwheel, carrying either the first or second support component. Furthermore, the limiting mechanism prevents displacement of the square rod without human intervention. The first and second support components can be switched, improving efficiency and effectively solving the problems of difficult and unstable bracket adjustment mentioned in the background technology. This greatly simplifies the operation, significantly reduces adjustment time, and allows for rapid erection of the vehicle frame, significantly improving work efficiency. It also facilitates switching between different support components, avoiding the problem of insufficient applicability due to a single support component.

[0014] 2. By setting up a limit mechanism, the square bar remains in a stable state when there is no human intervention, preventing displacement during maintenance and thus avoiding the motorcycle tipping over, thereby improving stability. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figures 1-4 Example 1: Refer to Figure 1-4An adjustable support device for a motorcycle bracket includes a U-shaped frame 1. Diagonal braces 4 are fixedly connected to both ends of the U-shaped frame 1. Hollow square tubes 5 are fixedly connected to the top of each of the two diagonal braces 4. Adjustment mechanisms 7 are provided on each of the two hollow square tubes 5. Each adjustment mechanism 7 includes a rotating rod 701 that rotatably passes through both sides of the middle portion of the hollow square tube 5. Circular holes adapted to the rotating rod 701 are provided on both sides of the hollow square tube 5. A handwheel 702 is fixedly connected to one end of the rotating rod 701, and a limiting post 707 is fixedly connected to the other end of the rotating rod 701. The surface of the limiting post 707... Multiple limiting grooves are provided. A gear 706 is fixedly sleeved on the inner middle part of the hollow square tube 5. A first fixing ring 703 is fixedly connected to one end of the rotating rod 701 near the handwheel 702. A first spring 704 is sleeved on the side of the rotating rod 701 near the first fixing ring 703 and the hollow square tube 5. A sliding collar 708 is sleeved on the rotating rod 701 between the hollow square tube 5 and the first spring 704. A second fixing ring 705 is fixedly sleeved on the inner side of the rotating rod 701 near the handwheel 702.

[0022] In this utility model, square rods 6 are slidably sleeved on the inner sides of the two hollow square tubes 5, and grooves 601 are opened at the ends of the two square rods 6 that are far apart from each other. A rack 602 is fixedly connected to the middle of the bottom of each groove 601, and the rack 602 meshes with the gear 706.

[0023] In this utility model, a first support member 603 is fixedly connected to one end of each of the two square rods 6 that are close to each other, and a second support member 604 is fixedly connected to the bottom of each of the two first support members 603.

[0024] In this utility model, a rubber anti-slip sleeve 2 is fixedly sleeved in the middle of the U-shaped frame 1, and a fixing member 3 is fixedly sleeved at both ends of the U-shaped frame 1. Rollers 301 are provided at the bottom of both fixing members 3.

[0025] As can be seen from the above description, the first embodiment of this utility model achieves the following technical effects: under the trigger of the limiting mechanism 8, the position of the square rod 6 can be adjusted by rotating the handwheel 702, which is convenient for use. At the same time, pushing the handwheel 702 compresses the first spring 704, at which time the gear 706 can separate from the rack 602, so that the square rod 6 can be quickly pulled out or inserted, which is convenient for switching between the second support member 604 and the first support member 603.

[0026] Example 2: The difference from Example 1 is that a limiting mechanism 8 is provided on the outer side of both hollow square tubes 5 near the limiting post 707. The limiting mechanism 8 includes a fixed plate 801 fixedly connected to the outer side of the hollow square tube 5. Vertical rods 802 are fixedly connected to both ends of the top of the fixed plate 801. The same limiting plate 804 is slidably sleeved on the circumferential surface of the two vertical rods 802. Circular holes adapted to the vertical rods 802 are opened at both ends of the limiting plate 804. A protrusion is provided in the middle of the top of the limiting plate 804, and the protrusion is adapted to the limiting groove of the limiting post 707. The limiting mechanism 8 also includes a limiting block fixedly connected to the top of the two vertical rods 802. A second spring 803 is sleeved on the bottom of the two vertical rods 802 at the limiting plate 804. A Z-shaped rod 805 is fixedly connected to one end of the limiting plate 804.

[0027] As can be seen from the above description, the second embodiment of this utility model achieves the following technical effects: by pressing the Z-shaped rod 805 of the limiting mechanism 8, the limiting plate 804 is lowered, compressing the second spring 803, causing the limiting plate 804 to separate from the limiting post 707. At this time, rotating the handwheel 702 causes the gear 706 to move with the rack 602, so that the square rod 6 can slide back and forth in the hollow square tube 5. When the Z-shaped rod 805 is not pressed, the position of the square rod 6 cannot be directly adjusted by the handwheel 702, thus improving the stability of the device.

[0028] Working Principle: This device operates similarly to a traditional motorcycle lifter, lifting the motorcycle. The distance between the two first support members 603 or the second support member 604 can be quickly adjusted by varying the distance between the sides of the motorcycle wheels. When adjustment is needed, pressing the Z-shaped rod 805 of the limiting mechanism 8 lowers the limiting plate 804, compressing the second spring 803 and separating the limiting plate 804 from the limiting post 707. Then, turning the handwheel 702 moves the gear 706, which in turn moves the rack 602, allowing the square rod 6 to slide back and forth within the hollow square tube 5, thus adjusting the distance between the two first support members 603 or the second support member 604. When switching between the first and second support members 603 and 604, pushing the handwheel 702 compresses the first spring 704, causing the gear 706 to move to one end of the hollow square tube 5, engaging the rack 602. 02 Separation: At this time, the card will quickly pull out the square rod 6, and the positions of the first support member 603 and the second support member 604 will be swapped. Then, the square rod 6 will be inserted into the hollow square tube 5. At this time, the rack 602 is located at the top of the gear 706 and can still mesh with the gear 706, so that the adjustment mechanism 7 can adjust the position of the square rod 6. Through the cooperation of the adjustment mechanism 7 and the square rod 6, the positions of the first support member 603 and the second support member 604 can be quickly adjusted, which can facilitate the switching of the first support member 603 and the second support member 604 and improve the efficiency of the operator. Through the setting of the limiting mechanism 8, the adjustment mechanism 7 will not loosen during use, causing the position of the square rod 6 to move, ensuring the safety of the device. When the handwheel 702 pushes to compress the first spring 704, due to the wide limiting post 707, the limiting post 707 will not separate from the top protrusion of the limiting plate 804 when it moves.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
