[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0019] The purpose of the present invention is to provide a walking device to solve the problems existing in the prior art. When the walking body needs to be fixed, the walking body is supported by supporting legs with more stable supporting effects to prevent the walking body from slipping. When the walking body needs to adjust its position, the walking body is supported by walking wheels to achieve the purpose of transferring the position of the walking body.

[0020] 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.

[0021] like Figures 1 to 3 As shown, this embodiment provides a walking device, including a walking body 1 and supporting legs 2, both located at the bottom of the walking body 1, and a lifting and controlling mechanism; wherein the walking body 1 can be a table body, a laboratory table body or other structures with position movement requirements. The lifting and controlling mechanism includes a telescopic mechanism, a movable plate 3, a vertical track 4 and a walking wheel 5. The telescopic end of the telescopic mechanism can move in the horizontal direction; the movable plate 3 is connected to the telescopic end of the telescopic mechanism, and the plate surface of the movable plate 3 is vertically arranged. An inclined groove 6 is arranged on the plate surface of the movable plate 3. The two ends of the inclined groove 6 have a height difference and are respectively the top and bottom ends of the inclined groove 6. The inclined groove 6 can be a straight groove or an arc groove. The vertical track 4 is fixed to the bottom of the walking body 1; the walking wheel 5 is mounted on a wheel frame 7, which is slidably arranged on the vertical track 4. The wheel frame 7 is also provided with a sliding pin slidably arranged in the inclined groove 6. When the telescopic mechanism is extended or retracted, it will drive the movable plate 3 to move horizontally. Under the limiting effect of the vertical track, the wheel frame 7 and the running wheel 5 will not move horizontally. The sliding pin will slide up and down along the inclined groove 6 under the interference of the inclined groove 6, thereby driving the wheel frame 7 and the running wheel 5 to slide up and down. Figure 2Taking the structure as an example, when the telescopic end of the telescopic mechanism is retracted, the sliding pin is located at the top of the inclined slot 6, and the bottom end of the walking wheel 5 is higher than the bottom end of the support leg 2, and the walking body 1 can be stably supported by the support leg 2; when the telescopic end of the telescopic mechanism is extended, the sliding pin is located at the bottom end of the inclined slot 6, and the bottom end of the walking wheel 5 is lower than the bottom end of the support leg 2, and the walking wheel 5 touches the ground to lift the walking body 1, and the walking wheel 5 can be used to transfer the position of the walking body 1.

[0022] This embodiment provides a support leg 2 and a lifting control mechanism at the bottom of the walking body 1, which can convert the horizontal extension and retraction action of the telescopic mechanism into the lifting action of the walking wheel 5. When the walking body 1 needs to be fixed, the support leg 2 with a more stable support effect is used to support the walking body 1 to prevent the walking body 1 from slipping. When the walking body 1 needs to adjust its position, the walking wheel 5 is used to support the walking body 1 to achieve the purpose of transferring the position of the walking body 1. Therefore, the walking device in this embodiment has the functions of both stable support and easy transfer.

[0023] In this embodiment, the sliding pin is rotatably arranged on the top of the wheel frame 7, so that the sliding pin rotates in the inclined groove 6, reducing the wear between the sliding pin and the groove wall of the inclined groove 6.

[0024] In this embodiment, a vertical slider 9 is slidably provided on the vertical track 4 , and the vertical slider 9 and the wheel frame 7 can be detachably connected by bolts.

[0025] In this embodiment, a horizontal track 10 is fixed to the bottom of the walking body 1. A movable plate 3 is slidably mounted on the horizontal track 10. The movable plate 3 is hinged to the output end of the telescopic mechanism. When the running wheels 5 touch the ground to support the walking body 1, the running wheels 5 transmit the supporting force to the horizontal track 10 via the wheel frame 7 and the sliding pin, thereby supporting the walking body 1.

[0026] In this embodiment, a horizontal slider 11 is slidably provided on the horizontal track 10 , and the horizontal slider 11 is detachably connected to the movable plate 3 via bolts.

[0027] In this embodiment, the bottom end of the inclined groove 6 is connected to a horizontal groove 12. When the sliding pin is located in the horizontal groove 12 at the bottom end of the inclined groove 6, the walking wheel 5 touches the ground to support the walking body 1. Since the sliding pin is located in the horizontal groove 12, it will not be subjected to horizontal force. Therefore, when the walking wheel 5 is used to support the walking body 1, no horizontal force will be applied to the telescopic mechanism, which can protect the telescopic mechanism.

[0028] In this embodiment, the telescopic mechanism is an electric cylinder 13 , which is connected to a motor 14 . The cylinder barrel of the electric cylinder 13 is hinged on a support 15 , and the support 15 is fixed to the bottom of the walking body 1 .

[0029] In this embodiment, the traveling wheel 5 is a universal wheel, which is convenient for moving in all directions.

[0030] In this embodiment, a protective cover 16 is provided at the bottom of the walking body 1. The support legs 2 and the lifting and lowering control mechanism are both disposed within the protective cover 16. The horizontal track 10 and the vertical track 4 are both fixedly connected to the inner wall of the protective cover 16. The cylinder barrel of the electric cylinder 13 is hingedly connected to the support 15 within the protective cover 16. Specifically, the protective cover 16 has a rectangular parallelepiped structure with an open bottom. The bottom end of the support legs 2 is lower than the bottom end of the protective cover 16, ensuring that the support legs 2 can provide support, rather than the protective cover 16 supporting the walking body 1. The top of the protective cover 16 is removably fixed to the bottom of the walking body 1 by bolts. The four side walls of the protective cover 16 are used to protect the support legs 2 and the lifting and lowering control mechanism.

[0031] In this embodiment, four groups of protective covers 16 , supporting legs 2 and lifting control mechanisms are provided. The protective covers 16 are distributed at the four corners of the bottom of the walking body 1 to provide stable support for the walking body 1 .

[0032] Adaptive changes based on actual needs are all within the scope of protection of the present invention.

[0033] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
