Description

Technical Field

[0001] This utility model relates to the field of motorcycle mudguard bracket technology, specifically a mudguard bracket fixing device. Background Technology

[0002] Motorcycles are two-wheeled or three-wheeled vehicles driven by gasoline engines and steered by the front wheel operated by handlebars. They are lightweight and flexible and are widely used for patrol purposes. When using a motorcycle, a mudguard bracket needs to be connected to the motorcycle, and then mudguards are installed on the bracket. Mudguards can prevent splashes from the tires from causing injury to the user's body or clothing when the motorcycle is in motion.

[0003] When installing mudguard brackets, a fixing device is needed to secure the mudguards. However, the fixing device does not have an anti-loosening mechanism, which can cause the fixing bolts to loosen, resulting in poor mudguard performance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mudguard bracket fixing device, which has the advantages of preventing the mudguard bracket from loosening and solves the problem that the fixing device is prone to loosening when fixing the mudguard bracket.

[0005] This utility model discloses a mudguard bracket fixing device, comprising a mudguard, with support frames on both sides of the mudguard, a fixing plate fitted at one end of each support frame, a limiting groove horizontally formed in the inner cavity of the fixing plate to match the support frame, and a movable groove vertically formed in the inner cavity of the fixing plate. A threaded sleeve is fitted at the bottom of the movable groove, and a screw is threadedly connected to the inner cavity of the threaded sleeve. A rotating plate is provided at the bottom of the screw, and the top of the screw extends through and to the top of the support frame. A locking hole matching the screw is formed in the inner cavity of the support frame. An anti-loosening component is provided at the top of the movable groove, comprising a movable cylinder, the top of which is fixedly connected to the movable groove. A push rod is movably fitted in the inner cavity of the movable cylinder, a limiting block is provided at the top of the push rod, a spring is provided at the connection between the top of the limiting block and the movable cylinder, and a push plate is provided at the bottom of the push rod, with the bottom of the push plate contacting the screw. First, the mounting plate is fixed to the frame. Then, the support bracket on the mudguard is inserted into the limiting groove on the mounting plate. At this time, the screw is inserted into the threaded sleeve. Rotating the rotating plate causes the screw to rotate, which in turn causes the screw to move upward through the threaded sleeve. When the top of the screw passes through the retaining hole in the support bracket, it can fix the support bracket. When the screw contacts the push plate, the push plate moves upward, which in turn causes the push rod to move upward. The push rod causes the limiting block to move upward, which in turn causes the spring to compress. When the rotating plate stops rotating, the inertia of the spring causes the limiting block to apply downward pressure. The limiting block transmits the pressure to the push rod, which in turn transmits the pressure to the push plate. The push plate can push the screw downward. In this way, the threads on the screw and the threads on the threaded sleeve are more tightly connected, preventing the connection between the screw and the threaded sleeve from loosening when subjected to external vibration.

[0006] The mud board support fixing device of this utility model has a limiting rod fixedly connected to one end of the inner cavity of the limiting groove. One end of the limiting rod passes through and extends into the inner cavity of the support frame. The inner cavity of the support frame is provided with a limiting hole that matches the limiting rod. Through the limiting rod and the limiting hole, the support frame can be initially limited when it is inserted into the limiting groove, thus preventing the support frame from shaking easily.

[0007] The mud plate bracket fixing device of this utility model has a ball bearing movably embedded on the surface of the limiting block, and the surface of the ball bearing is in close contact with the inner wall of the movable cylinder. Through the ball bearing, this utility model can make the limiting block move smoothly when it moves, and avoid the situation of the limiting block getting stuck when it moves in the movable cylinder.

[0008] The mudguard bracket fixing device of this utility model, wherein the connection between the two sides of the mudguard and the support frame is fixedly connected by connecting blocks, and the two support frames are arranged symmetrically about the mudguard. The connecting blocks can fix the connection between the support frame and the mudguard, so that the mudguard is more firmly fixed on the support frame and avoids the situation where the mudguard is easy to fall off the support frame during use.

[0009] The mud board support fixing device of this utility model has anti-slip threads on the surface of the rotating plate, and the number of anti-slip threads is not less than fifteen. The anti-slip threads can prevent the rotating plate from slipping when the user rotates the rotating plate, thus preventing the plate from falling off.

[0010] The mudguard bracket fixing device of this utility model has an installation groove on the inner side of the fixing plate, and the installation groove is set on the external frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model first fixes the fixed plate to the vehicle frame, then inserts the support frame on the mudguard into the limiting groove on the fixed plate. At this time, the screw is inserted into the threaded sleeve. Rotating the rotating plate drives the screw to rotate, and the threaded sleeve drives the screw to move upward. When the top of the screw passes through the locking hole in the support frame, it can fix the support frame. When the screw contacts the push plate, the push plate will move upward, and the push plate drives the push rod to move upward, and the push rod drives the limiting block to move upward. The limiting block drives the spring to compress. When the rotating plate stops rotating, the inertia of the spring drives the limiting block to apply downward pressure, and the limiting block transmits the pressure to the push rod, and the push rod transmits the pressure to the push plate. The push plate can push the screw downward. In this way, the threads on the screw and the threads on the threaded sleeve are more tightly connected, and the connection between the screw and the threaded sleeve is prevented from loosening when subjected to external vibration.

[0013] 2. This utility model uses ball bearings to ensure smooth movement of the limiting block, thus preventing jamming when the limiting block moves within the movable cylinder.

[0014] The limiting rod and limiting hole can initially limit the support frame when it is inserted into the limiting groove, thus preventing the support frame from shaking.

[0015] The connecting block can fix the connection between the support frame and the mudguard, making the mudguard more securely fixed to the support frame and preventing the mudguard from easily falling off the support frame during use.

[0016] The anti-slip threads prevent the rotating plate from slipping when the user rotates it, thus preventing it from falling off. Attached Figure Description

[0024] Please see Figure 1-4The present invention relates to a mudguard bracket fixing device, comprising a mudguard 1, with support frames 3 on both sides of the mudguard 1. A fixing plate 4 is fitted onto one end of each support frame 3. The inner cavity of the fixing plate 4 has a horizontally opening limiting groove 6 adapted to the support frame 3. The inner cavity of the fixing plate 4 has a vertically opening movable groove 11. A threaded sleeve 9 is fitted onto the bottom of the movable groove 11. A screw rod 8 is threadedly connected to the inner cavity of the threaded sleeve 9. A rotating plate 10 is provided at the bottom of the screw rod 8. The top of the screw rod 8 passes through and extends to the top of the support frame 3. The inner cavity of the support frame 3 has a corresponding limiting groove 6 adapted to the screw rod 8. The top of the inner cavity of the slot 12 and the movable groove 11 is provided with an anti-loosening component 5. The anti-loosening component 5 includes a movable cylinder 501, and the top of the movable cylinder 501 is fixedly connected to the movable groove 11. A push rod 505 is movably sleeved in the inner cavity of the movable cylinder 501. A limiting block 502 is provided at the top of the push rod 505. A spring 503 is provided at the connection between the top of the limiting block 502 and the movable cylinder 501. A push plate 506 is provided at the bottom of the push rod 505, and the bottom of the push plate 506 contacts the screw 8. In this utility model, the fixing plate 4 is first fixed on the frame, and then... The support frame 3 on the mudguard 1 is inserted into the limiting groove 6 on the fixed plate 4. At this time, the screw 8 is inserted into the screw sleeve 9. Rotating the rotating plate 10 causes the screw 8 to rotate, which in turn causes the screw 8 to move upward through the screw sleeve 9. When the top of the screw 8 passes through the locking hole 12 in the support frame 3, it can fix the support frame 3. When the screw 8 contacts the push plate 506, the push plate 506 will move upward, which in turn causes the push rod 505 to move upward, which in turn causes the limiting block 502 to move upward. The position block 502 drives the spring 503 to compress. When the rotating plate 10 stops rotating, the inertia of the spring 503 drives the limit block 502 to apply downward pressure. The limit block 502 transmits the pressure to the push rod 505, and the push rod 505 transmits the pressure to the push plate 506. The push plate 506 can push the screw 8 downward, so that the threads on the screw 8 and the threads on the screw sleeve 9 are more tightly connected, avoiding the loosening of the connection between the screw 8 and the screw sleeve 9 when subjected to external vibration.

[0025] One end of the inner cavity of the limiting groove 6 is fixedly connected to the limiting rod 7. One end of the limiting rod 7 passes through and extends into the inner cavity of the support frame 3. The inner cavity of the support frame 3 is provided with a limiting hole 13 that matches the limiting rod 7. Through the limiting rod 7 and the limiting hole 13, when the support frame 3 is inserted into the limiting groove 6, it can play a preliminary limiting role on the support frame 3, thus avoiding the support frame 3 from easily shaking.

[0026] The surface of the limiting block 502 is movably embedded with a ball bearing 504, and the surface of the ball bearing 504 is in close contact with the inner wall of the movable cylinder 501. Through the ball bearing 504, the limiting block 502 can move smoothly, thus avoiding the situation of jamming when the limiting block 502 moves in the movable cylinder 501.

[0027] Both sides of the mudguard 1 are fixedly connected to the support frame 3 by connecting blocks 2. The two support frames 3 are arranged symmetrically about the mudguard 1. The connecting blocks 2 can fix the connection between the support frame 3 and the mudguard 1, so that the mudguard 1 is more firmly fixed on the support frame 3, and avoids the mudguard 1 from falling off the support frame 3 during use.

[0028] The surface of the rotating plate 10 is provided with anti-slip threads, and the number of anti-slip threads is not less than fifteen. The anti-slip threads can prevent the rotating plate 10 from slipping when the user rotates it, thus preventing the rotating plate 10 from falling off.

[0029] The inner side of the fixed plate 4 is provided with a mounting groove, and the mounting groove is set on the external frame.

[0030] When using this utility model: First, fix the fixing plate 4 to the vehicle frame. Then, insert the support frame 3 on the mudguard 1 into the limiting groove 6 on the fixing plate 4. At this time, the screw 8 is inserted into the screw sleeve 9. Rotate the rotating plate 10, which drives the screw 8 to rotate. The screw sleeve 9 drives the screw 8 to move upward. When the top of the screw 8 passes through the locking hole in the support frame 3, it can fix the support frame 3. When the screw 8 contacts the push plate 506, the push plate 506 will move upward. The push plate 506 drives the push rod 505 to move upward, and the push rod 505 drives the limiting groove 6. Block 502 moves upward, and the spring 503 is squeezed by the limiting block 502. When the rotating plate 10 stops rotating, the inertia of the spring 503 drives the limiting block 502 to apply downward pressure. The pressure is transmitted to the push rod 505 through the limiting block 502, and then to the push plate 506 through the push rod 505. The push plate 506 can push the screw 8 downward, so that the threads on the screw 8 and the threads on the sleeve 9 are more tightly connected, and the connection between the screw 8 and the sleeve 9 is prevented from loosening when subjected to external vibration.
