Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation of the present utility model.

[0020] Please refer to Figures 1 to 4 , wherein Figure 1 is the structural schematic diagram of the trolley wheel steering assembly of the present utility model, Figure 2 is the front view of the trolley wheel steering assembly of the present utility model, Figure 3 is the side view of the trolley wheel steering assembly of the present utility model, Figure 4 is of the present utility model Figure 3 Structural sectional view taken along line A-A.

[0021] The present utility model provides a trolley wheel steering assembly, including a wheel body 101, a rotating rod 102 and a rotating assembly. The rotating rod 102 is rotatably connected to the wheel body 101 and penetrates through the wheel body 101, and the rotating assembly is arranged outside the wheel body 101;

[0022] The rotating assembly includes a first limit block 103, a second limit block 104, a fixing frame 105, a buffer component, and a braking component. The first limit block 103 is fixedly connected to the rotating rod 102 and is located at one end of the rotating rod 102. The second limit block 104 is fixedly connected to the rotating rod 102 and is located at the end of the rotating rod 102 away from the first limit block 103. The fixing frame 105 is fixedly connected to the rotating rod 102, wraps the rotating rod 102, and the fixing frame 105 is located above the wheel body 101. The buffer component is arranged above the fixing frame 105, and the braking component is arranged on one side of the fixing frame 105.

[0023] In this embodiment, the first limit block 103 and the second limit block 104 prevent the rotating rod 102 from falling off the fixing frame 105. The wheel body 101 can be braked by implementing the braking component, and the steering and buffering of the wheel body 101 can be achieved through the buffer component, reducing the impact on the normal driving of the trolley due to vibration.

[0024] Further, the buffer component includes a mounting plate 106, a support telescopic rod 107, a spring 108, an auxiliary telescopic rod 109, and a fixing plate 110. The mounting plate 106 is arranged above the fixing frame 105. One end of the support telescopic rod 107 is fixedly connected to the mounting plate 106 and is located below the mounting plate 106. The spring 108 is fixedly connected to the mounting plate 106 and wraps the support telescopic rod 107. The fixing plate 110 is fixedly connected to the support telescopic rod 107 and is located at the end of the support telescopic rod 107 away from the mounting plate 106. The bottom surface of the fixing plate 110 has holes. The auxiliary telescopic rod 109 is fixedly connected to the fixing plate 110 and is located between the fixing plate 110 and the mounting plate 106. One end of the auxiliary telescopic rod 109 away from the fixing plate 110 is fixedly connected to the mounting plate 106.

[0025] In this embodiment, the mounting plate 106 can connect the overall trolley wheel steering assembly to the external trolley. When the wheel body 101 vibrates due to uneven road surfaces, the support telescopic rod 107 and the spring 108 will start to contract. During the contraction of the spring 108, part of the vibration is converted into elastic potential energy. When the vibration disappears, the spring 108 will return to its original shape, thereby reducing the impact on the mounting plate 106 and the trolley. The auxiliary telescopic rod 109 can increase the stability of the buffer component during buffering.

[0026] Furthermore, the buffer component further includes a connecting rod 111 and a rotating plate 112. One end of the connecting rod 111 is rotatably connected to the fixing plate 110 and is located inside the fixing plate 110. The connecting rod 111 is adapted to the hole on the bottom surface of the fixing plate 110. The rotating plate 112 is fixedly connected to the connecting rod 111 and is located below the connecting rod 111. The rotating plate 112 is fixedly connected to the fixing frame 105.

[0027] In this embodiment, when the wheel body 101 starts to turn, the rotating plate 112 will drive the connecting rod 111 to rotate inside the fixing plate 110, thereby increasing the stability of the wheel body 101 when turning.

[0028] Furthermore, the braking component includes a hydraulic pipe 113, a hydraulic rod 114 and a pedal 115. The hydraulic pipe 113 is fixedly connected to the fixing frame 105 and is located on one side of the fixing frame 105. The hydraulic rod 114 is slidably connected to the hydraulic pipe 113 and is located inside the hydraulic pipe 113. The pedal 115 is fixedly connected to the hydraulic rod 114 and is located at one end of the hydraulic rod 114 away from the hydraulic pipe 113.

[0029] In this embodiment, hydraulic oil is stored between the hydraulic pipe 113 and the hydraulic rod 114. When the pedal 115 is depressed, the pedal 115 contacts the wheel body 101 to brake the wheel body 101. At the same time, the hydraulic rod 114 will squeeze the hydraulic oil in the hydraulic pipe 113. When the external force on the pedal 115 is removed, the hydraulic pipe 113 will reset the hydraulic rod 114 in order to restore the internal pressure balance, thereby driving the pedal 115 to reset.

[0030] Furthermore, the braking component further includes an anti-slip plate 116. The anti-slip plate 116 is fixedly connected to the pedal 115 and is located above the pedal 115.

[0031] In this embodiment, the anti-slip plate 116 increases the friction when the pedal 115 is depressed and prevents slipping.

[0032] The above-disclosed is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of the rights of the present utility model. Those of ordinary skill in the art can understand the entire or part of the processes of the above embodiments, and the equivalent changes made according to the claims of the present utility model still fall within the scope covered by the utility model.
