However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] Example

[0020] Please refer to Figures 1-4 As shown, the utility model provides a universal wheel with lockable steering, the upper end of the support plate 1 is fixedly connected to a sleeve 19, the sleeve 19 is located at the center of the upper end of the support plate 1, a connecting plate 20 is slidably arranged inside the sleeve 19, one side of the sleeve 19 is fixedly connected to a bracket 21, a cross bar 22 is passed through the bracket 21, one end of the cross bar 22 is fixedly connected to a handle 23, and a spring 24 is fixedly connected between the handle 23 and the bracket 21, the other end of the cross bar 22 is fixedly connected to a second limit block 25, and a plurality of second limit grooves 26 are evenly spaced on one side of the connecting plate 20, and the upper end of the connecting plate 20 is fixedly connected to a mounting plate 27.

[0021] During use, by pulling the handle 23, the handle 23 drives the cross bar 22 and the second limit block 25 to move, and at the same time the spring 24 contracts until the second limit block 25 leaves the second limit groove 26, and then pulls and moves the connecting plate 20 from the sleeve 19 until the connecting plate 20 moves to the appropriate position, and then stops pulling the handle 23. Under the elastic force of the spring 24, the second limit block 25 can be inserted into the second limit groove 26, and the connecting plate 20 can be limited and fixed, so that the distance between the mounting plate 27 and the wheel 4 can be adjusted to meet different usage requirements.

[0022] As a further implementation of this embodiment, Figure 1-Figure 5 As shown, a rotating shaft 2 is provided at the lower end of the support plate 1, and a frame 3 is fixedly connected to the lower end of the rotating shaft 2. A wheel 4 is rotatably provided on the inner side of the frame 3, and an annular plate 5 is fixedly connected to the outer side of the rotating shaft 2. A plurality of first limiting grooves 6 are provided on the annular plate 5. A vertical plate 7 is fixedly connected to one side of the support plate 1, and a horizontal plate 8 is passed through the vertical plate 7. A first limiting block 9 is fixedly connected to one side of the horizontal plate 8. A first slot 10 and a second slot 11 are respectively provided at the upper end of the horizontal plate 8, and the first slot 10 and the second slot 11 are both matched with the fixing assembly. The fixing assembly is as follows: a fixing block 12 is fixedly connected to the upper end of the support plate 1, and a fixing plate 13 is passed through the fixing block 12. A vertical rod 14 is fixedly connected to one side of the fixing plate 13, and an insert block 15 is fixedly connected to one end of the vertical rod 14, and a threaded rod 16 is fixedly connected to the upper end of the fixing block 12. A pressure plate 17 is threadedly connected to the threaded rod 16, and an anti-slip pad 18 is provided on one side of the pressure plate 17.

[0023] When the vehicle is in use, the wheel 4 can be rotated to the required direction by the rotating shaft 2, and then the pressure plate 17 is rotated to make the pressure plate 17 move upward a certain distance, and the fixing plate 13 is moved upward a certain distance. The fixing plate 13 moves and drives the vertical rod 14 and the insert block 15 to move upward, and makes the insert block 15 leave the second slot 11, and then moves the cross plate 8 so that the first limit block 9 on one side of the cross plate 8 is inserted into the first limit groove 6. At this time, the first slot 10 is located directly under the insert block 15, and the fixing plate 13 is placed on the support plate 1. At this time, the insert block 15 is inserted into the first slot 10, and the pressure plate 17 is rotated in the opposite direction so that the anti-slip pad 18 on one side of the pressure plate 17 is tightly fixed to the fixing plate 13, thereby realizing the limit fixation of the cross plate 8, and then realizing locking the direction of rotation of the wheel 4. Through this device, the steering of the wheel 4 can be well locked, so that the wheel 4 can well meet the requirements of continuing to move forward in a certain direction.

[0024] Specific working principle: When in use, the wheel 4 can be rotated to the required direction through the rotating shaft 2, and then the pressure plate 17 is rotated to move the pressure plate 17 upward for a certain distance, and at the same time, the fixed plate 13 is moved upward for a distance. The movement of the fixed plate 13 drives the vertical rod 14 and the plug 15 to move upward, and the plug 15 leaves the second slot 11, and then the cross plate 8 is moved so that the first limit block 9 on one side of the cross plate 8 is inserted into the first limit groove 6. At this time, the first slot 10 is located directly below the plug 15, and the fixed plate 13 is placed on the support plate 1. At this time, the plug 15 is inserted into the first slot 10, and the pressure plate 17 is rotated in the opposite direction so that the anti-slip pad 18 on one side of the pressure plate 17 is aligned with the fixed plate 13. The plate 13 is tightly fixed, and the anti-slip pad 18 on the pressure plate 17 can make the pressure plate 17 better fix the fixing plate 13 to prevent relative sliding between the pressure plate 17 and the fixing plate 13, thereby achieving the limit fixation of the cross plate 8, and then achieving locking the rotation direction of the wheel 4. Through this device, the steering of the wheel 4 can be well locked, so that the wheel 4 can be well satisfied to continue to move in a certain direction; in addition, when the insert block 15 is inserted into the second slot 11, the first limit block 9 is no longer inserted into the first limit groove 6, so that the steering of the wheel 4 is no longer locked, and the wheel 4 can rotate in any direction, thereby meeting different applicable environments.
