DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Reference Figure 1-2 The present invention provides a universal wheel bracket with stable brake, comprising a mounting seat 1, a rotating seat 2 is rotatably arranged at the bottom of the mounting seat 1, two support plates 3 are fixedly connected to the bottom surface of the rotating seat 2, and a roller 4 is rotatably installed between the two ends of the two support plates 3 away from the rotating seat 2; a mounting plate 5 is fixedly connected to the side of the support plate 3, a first limiting component is installed between the two mounting plates 5, and the first limiting component is arranged corresponding to the side of the roller 4; a second limiting component that limits the rotation of the rotating seat 2 is installed on the bottom surface of the rotating seat 2. While the control component controls the first limiting component to limit the roller 4, it can drive the second limiting component to limit the rotating seat 2, so that the roller 4 cannot continue to rotate, and the rotating seat 2 can no longer continue to rotate, thereby realizing double limiting of the whole, ensuring that the bearing device can be stable at the specified position and is not easy to move.

[0019] In a further optimized solution, a support column 6 is rotatably connected between the two mounting plates 5, and a limiting piece 7 is fixedly connected to the support column 6. The limiting piece 7 is a spring steel sheet, and the limiting piece 7 is bent. The middle bending area of ​​the limiting piece 7 is arranged corresponding to the support column 6. The limiting piece 7 is bent and fixed to the support column 6, so that when one end of the limiting piece 7 with the limiting plate 8 moves downward, the other end can move upward to cooperate with the second limiting component, thereby realizing double limiting.

[0020] Further optimization scheme, the first limit component includes a through hole opened at one end of the limit piece 7, two limit plates 8 are fixedly connected in the through hole, the two limit plates 8 are arranged opposite to each other, the inclination direction of the two limit plates 8 is arranged corresponding to the rotation direction of the roller 4, and a control component for controlling the limit piece 7 to move downward with one end of the limit plate 8 is installed between the two mounting plates 5. The control component controls the limit piece 7 with the limit plate 8 to move downward, thereby driving the two inclined limit plates 8 to contact the side wall of the roller 4, thereby limiting it and preventing the roller 4 from continuing to rotate.

[0021] In a further optimized solution, the control assembly includes a pedal block 9 located between the two mounting plates 5 and rotatably connected to the mounting plates 5 at one end, a connecting plate 10 is fixedly connected to the top surface of the end of the limiting plate 7 close to the limiting plate 8, and a moving block 11 is arranged above the limiting plate 8. The middle of the moving block 11 is rotatably connected to the top of the connecting plate 10, and the end of the moving block 11 close to the pedal block 9 is rotatably connected to the pedal block 9. By stepping on the pedal block 9, the pedal block 9 is driven to rotate downward, and then the connecting plate 10 and the end of the limiting plate 7 with the limiting plate 8 are pushed downward by the moving block 11.

[0022] Further optimization scheme, the second limiting component includes a limiting ring 12 fixedly connected to the bottom surface of the rotating seat 2, and a plurality of limiting protrusions 13 are fixedly connected to the side of the bottom surface of the limiting ring 12, and the plurality of limiting protrusions 13 are distributed in a circular shape; an arc groove 14 is provided at one end of the limiting piece 7 away from the limiting plate 8, and the arc groove 14 is arranged corresponding to the limiting protrusion 13, and the side wall frame of the arc groove 14 is located between two adjacent limiting protrusions 13. When the control component controls the end of the limiting piece 7 with the connecting plate 10 to move downward, the end with the arc groove 14 moves upward, so that the side frame of the arc groove 14 moves between the limiting protrusions 13, thereby limiting the limiting ring 12, making it unable to continue to rotate, thereby affecting the rotation of the rotating seat 2, and cooperating with the first limiting component to achieve double limiting.

[0023] In a further optimized solution, an elastic gasket 15 is fixedly connected to the middle of the limit plate 7, and a top plate is fixedly connected to the top of the two mounting plates 5, and the elastic gasket 15 abuts against the top plate. The elastic gasket 15 can apply elastic force to the limit plate 7, so that after the limit is completed, the foot pedal 9 can be lifted up to drive the limit plate 7 to separate from the limit protrusion 13 and the roller 4, and no longer limit.

[0024] Further optimization scheme, the mounting seat 1 and the rotating seat 2 are provided with bearing grooves correspondingly, and the first bearing 16 is installed in the bearing groove; the bottom surface of the mounting seat 1 is fixedly connected with a connecting column 17, and the connecting column 17 is arranged through the rotating seat 2, and a second bearing 18 is arranged between the connecting column 17 and the rotating seat 2, and a nut 19 is threadedly connected to the end of the connecting column 17, and the connecting column 17 and the nut 19 are both located in the limiting ring 12. The service life of the universal wheel bracket can be increased by providing the first bearing 16 and the second bearing 18, and the mounting seat 1 and the rotating seat 2 are made into a detachable split structure by matching the connecting column 17 and the nut 19, so that the damaged parts inside can be replaced conveniently and quickly; the second bearing 18 is a tapered roller bearing, which can increase the load in the vertical direction and increase the overall stability.

[0025] The working process of the present invention is as follows: when braking is required, the pedal block 9 is only required to be pressed down with the foot. The pedal block 9 will move downward through the moving block 11 to squeeze the connecting plate 10 and the end of the limiting plate 7, so that the limiting plate 8 squeezes the side wall of the roller 4. Since the two limiting plates 8 are arranged oppositely and tilted, the roller 4 can be prevented from continuing to rotate. At the same time, when one end of the limiting plate 7 with the limiting plate 8 moves downward, it will drive the other end to move upward, so that the frame of the arc groove 14 moves upward and moves between the two limiting protrusions 13, so that the limiting ring 12 cannot rotate, thereby limiting the rotating seat 2 and preventing it from rotating, thereby achieving double limiting.

[0026] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.
