Description

Technical Field

[0001] The utility model relates to the technical field of motorcycle steering locking, in particular to an external motorcycle steering locking mechanism. Background Technique

[0002] A motorcycle is a two-wheeled or three-wheeled vehicle driven by a gasoline engine and steered by a handlebar to control the front wheel. It is light, flexible, and travels fast. It is widely used for patrol, passenger and freight transportation, etc., and is also used as a sports equipment.

[0003] When the existing motorcycles are parked, they usually lock the steering direction to improve the anti-theft performance. The existing steering locking anti-theft devices usually need to punch holes in the steering column riser and the frame, and then insert the lock tongue into the holes for locking.

[0004] When the existing steering locking mechanism is installed, after punching holes in the steering column riser and the frame, the strength of the frame riser and the steering column riser may be reduced, posing a risk of fracture during riding and stunts; therefore, it does not meet the existing requirements, and for this reason, we propose an external motorcycle steering locking mechanism. Content of the Utility Model

[0005] The purpose of the utility model is to provide an external motorcycle steering locking mechanism to solve the problems in the above background technique that when the steering locking mechanism is installed, after punching holes in the steering column riser and the frame, the strength of the frame riser and the steering column riser may be reduced, posing a risk of fracture during riding and stunts.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an external motorcycle steering locking mechanism, including a steering column, a locking limit platform is fixedly installed at the top of the steering column, a steering locking frame is rotatably installed at the top of the locking limit platform, an upper connecting frame is rotatably installed at the top of the steering locking frame, a fixing block is fixedly installed at the top of the steering locking frame, and a clamping groove is provided on the bottom surface of the upper connecting frame, and the fixing block slides into the inside of the clamping groove.

[0007] Preferably, a lock tongue hole is provided on one side of the steering locking frame, and a lock tongue is slidably installed inside the lock tongue hole.

[0008] Preferably, a limit convex plate is fixedly installed on one side of the locking limit platform, a locking groove is provided outside the limit convex plate, the lock tongue slides into the inside of the locking groove, and the surface of the lock tongue fits with the surface of the limit convex plate.

[0009] Preferably, a lower connecting frame is rotatably installed at the bottom end of the steering column, and a frame is fixedly connected to the front side of the steering column.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0011] 1. Through the cooperation of the steering lock bracket and the upper connecting bracket, when the device is in use, the fixing block can be inserted into the inside of the clamping groove, so that the steering lock bracket and the upper connecting bracket are connected. At this time, when the upper connecting bracket rotates, the steering lock bracket will follow the upper connecting bracket to rotate due to the blocking of the fixing block;

[0012] 2. Through the cooperation of the lock tongue and the limit convex plate, when the device needs to lock the steering, the upper connecting bracket can be first pulled to the angle to be locked. At this time, the steering lock bracket rotates synchronously with the upper connecting bracket. At this time, the key can be rotated to drive the lock tongue inside the lock tongue hole to be pushed inwards. After the lock tongue is pushed in, it will be stuck into the inside of the locking groove, and one side of the lock tongue will be attached to the surface of one side of the limit convex plate. At this time, the lock tongue is blocked by the limit convex plate. At this time, when the upper connecting bracket continues to rotate, it will not be able to rotate due to the blocking of the lock tongue, thus completing the steering lock of the device;

[0013] 3. Through the cooperation of the locking limit platform installed on the outside of the steering column and the steering lock bracket, when the device is in use, it realizes the locking of the vehicle steering through the locking limit platform and the steering lock bracket without damaging the vehicle frame and the steering column, avoiding the punching operation on the vehicle frame and the steering column, thus avoiding the reduction of the strength of the steering column and the vehicle frame and causing the risk of fracture during riding and stunts.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Please refer to Figures 1 to 4 For an embodiment provided by the present utility model: An external steering locking mechanism for a motorcycle, which includes a steering column 1. A locking limit platform 3 is fixedly installed at the top end of the steering column 1. A steering locking frame 4 is rotatably installed at the top end of the locking limit platform 3. An upper connecting frame 5 is rotatably installed at the top end of the steering locking frame 4. A fixing block 6 is fixedly installed at the top end of the steering locking frame 4. A clamping groove is provided on the bottom surface of the upper connecting frame 5. The fixing block 6 slides into the inside of the clamping groove.

[0021] Through the cooperation of the steering locking frame 4 and the upper connecting frame 5, when the device is in use, by inserting the fixing block 6 into the inside of the clamping groove, the connection between the steering locking frame 4 and the upper connecting frame 5 can be achieved. At this time, when the upper connecting frame 5 rotates, the steering locking frame 4 will follow the upper connecting frame 5 to rotate due to the blocking of the fixing block 6.

[0022] A lock tongue hole 7 is provided on one side of the steering locking frame 4. A lock tongue 8 is slidably installed inside the lock tongue hole 7.

[0023] A limit convex plate 9 is fixedly installed on one side of the locking limit platform 3. A locking groove 10 is provided on the outside of the limit convex plate 9. The lock tongue 8 slides into the inside of the locking groove 10. The surface of the lock tongue 8 is in contact with the surface of the limit convex plate 9.

[0024] Through the cooperation of the lock tongue 8 and the limit convex plate 9, when the device needs to lock the steering, the upper connecting frame 5 can be first pulled to the angle to be locked. At this time, the steering locking frame 4 rotates synchronously with the upper connecting frame 5. At this time, by turning the key, the key drives the lock tongue 8 inside the lock tongue hole 7 to be pushed inwards. After the lock tongue 8 is pushed in, it will be stuck in the inside of the locking groove 10, and one side of the lock tongue 8 will be in contact with one side surface of the limit convex plate 9. At this time, the lock tongue 8 is blocked by the limit convex plate 9. Continuing to rotate the upper connecting frame 5 will not be able to rotate due to the blocking of the lock tongue 8, thus completing the steering lock of the device.

[0025] A lower connecting frame 11 is rotatably installed at the bottom end of the steering column 1. The front side of the steering column 1 is fixedly connected to a vehicle frame 2.

[0026] Through the cooperation of the locking limit platform 3 and the steering locking frame 4 installed on the outside of the steering column 1, when the device is in use, it realizes the locking of the vehicle steering through the locking limit platform 3 and the steering locking frame 4 without damaging the vehicle frame 2 and the steering column 1, avoiding the perforation operation on the vehicle frame 2 and the steering column 1, thus avoiding the reduction of the strength of the steering column 1 and the vehicle frame 2, and causing the risk of fracture during riding and stunts.

[0027] When the external steering locking mechanism of the motorcycle is in use and the device needs to lock the steering, first stop the vehicle, and then pull the upper connecting frame 5 to the angle to be locked. At this time, since the fixed block 6 is inserted into the inside of the clamping groove, the steering locking frame 4 and the upper connecting frame 5 are connected. At this time, when the upper connecting frame 5 rotates, the steering locking frame 4 will rotate following the upper connecting frame 5 due to the blocking of the fixed block 6. Then, by inserting and turning the motorcycle key, the key drives the lock tongue 8 inside the lock tongue hole 7 to be pushed inward. After the lock tongue 8 is pushed in, it will be stuck into the inside of the locking groove 10, and one side of the lock tongue 8 will be attached to the surface of one side of the limit convex plate 9. At this time, the lock tongue 8 is blocked by the limit convex plate 9. At this time, continuing to rotate the upper connecting frame 5 will not be able to rotate due to the blocking of the lock tongue 8, thus completing the steering locking of the device.

[0028] Through the cooperation of the locking limit platform 3 installed outside the steering column 1 and the steering locking frame 4, it is realized that the vehicle steering can be locked by the locking limit platform 3 and the steering locking frame 4 without damaging the vehicle frame 2 and the steering column 1, avoiding the perforation operation on the vehicle frame 2 and the steering column 1, thereby avoiding the reduction of the strength of the steering column 1 and the vehicle frame 2, and causing the risk of fracture during riding and stunts.
