[0029] The following is combined with Figure 1-8 , the embodiments of the utility model are further described in detail.

[0030] A four-star foot with a swing and rotation function 1, such as Figure 1 , Figure 2 , Figure 3 As shown, it includes a first supporting foot 2 and a second supporting foot 3 arranged crosswise with the first supporting foot 2. A first groove 21 is arranged along the width direction of the first supporting foot 2 on the side facing the second supporting foot 3, and a second groove 31 is arranged along the width direction of the second supporting foot 3 on the side facing the first supporting foot 2. The side of the first supporting foot 2 away from the first groove 21 is clamped in the second groove 31, and the side of the second supporting foot 3 away from the second groove 31 is clamped in the first groove 21. An open first mounting groove 22 is arranged along the length direction of the first supporting foot 2 on the side away from the first groove 21, and an open second mounting groove 32 is arranged along the length direction of the second supporting foot 3 on the side provided with the second groove 31. The first mounting groove 22 and the second mounting groove 32 are used to enclose a mounting position for mounting a rotating component 6. Both ends of the first supporting foot 2 and the second supporting foot 3 are provided with a support portion 5 for supporting them away from the ground.

[0031] The first supporting leg 2 and the second supporting leg 3 are cross-arranged to form a four-star foot seat, and the upper sides thereof are respectively provided with a first mounting groove 22 and a second mounting groove 32, so as to facilitate the installation of the rotating component 6. The lower side of the first supporting leg 2 is provided with a first groove 21, and the upper side of the second supporting leg 3 is provided with a second groove 31. The first supporting leg 2 and the second supporting leg 3 are fast assembled by being engaged with the first groove 21 and the second groove 31, which makes installation and disassembly more convenient, maintenance more convenient, and the cost is lower.

[0032] In the first embodiment, the end surface of the opening side of the first groove 21 is flush with the side of the second supporting foot 3 facing away from the second groove 31, so as to maintain the flatness of the installation position and improve the efficiency of installation.

[0033] Specifically, the size of the first groove 21 is set to be the same as the size of the second groove 31, so as to increase the contact area and make the connection more stable.

[0034] A screw hole is provided at both ends of the first mounting groove 22 and the second mounting groove 32. After the first supporting leg 2 and the second supporting leg 3 are clamped, the base of the rotating component 6 is screwed into the corresponding screw hole to fix the rotating component 6, the first supporting leg 2 and the second supporting leg 3, and the base is located in the mounting position enclosed by the first mounting groove 22 and the second mounting groove 32.

[0035] Support parts 5 are provided at both ends of the first supporting leg 2 and the second supporting leg 3 on the side away from the rotating part 6, and reserved mounting holes 51 are provided at the lower ends of the supporting legs 5. Various sliding structures can be installed through the mounting holes 51 to facilitate the movement and transportation of the four-star leg and the structure thereon.

[0036] In this second embodiment, please refer to Figure 4 , Figure 5 , Figure 8 As shown, the structure of the second groove 31 and the outer side of the first support leg 2 is different from that in the above embodiment. A plurality of protruding limit strips 33 are provided on at least one inner side wall of the second groove 31. The outer side wall of the first support leg 2 is correspondingly provided with a limit groove 23, and the limit strip 33 is clamped in the corresponding limit groove 23 to improve the stability and flatness of the connection and facilitate the installation of the rotating component 6.

[0037] One end of the limiting groove 23 is connected to the first groove 21, and the other end of the limiting groove 23 is opened to be connected to the outside, which is convenient for installation and removal and easy to observe whether it is installed in place.

[0038] The limiting strip 33 is configured as a cylindrical structure or a square structure, which is simple in structure and saves cost. The lower end of the limiting strip 33 can be configured as a tapered end, so that the limiting strip 33 can be quickly aligned with the limiting groove 23.

[0039] Please refer to Figure 5 ,Figure 6 , Figure 7 , on the outer side wall of the first support leg 2, an open first fixing groove 24 is further provided, and on the inner side wall of the second groove 31, a second fixing groove 34 communicating with the first fixing groove 24 is correspondingly provided. The first fixing groove 24 and the second fixing groove 34 enclose a closed cavity around. The four-star foot 1 with rocking and rotating further includes a fixing column 4, and the fixing column 4 is press-fitted into the cavity enclosed by the first fixing groove 24 and the second fixing groove 34, facilitating the clamping of the first support leg 2 and the second support leg 3. After installing the fixing column 4, the clamping of the first support leg 2 and the second support leg 3 is more firm and the stability is higher.

[0040] Among them, the fixing column 4 can be set as a cylindrical structure or a square structure. The fixing column 4 is preferably a square structure, with more stable clamping and greater frictional force, which can prevent the fixing column 4 from sliding relative to the first fixing groove 24 and the second fixing groove 34.

[0041] Specifically, the cross-sections of the first fixing groove 24 and the second fixing groove 34 are set as a V-shaped structure, and the fixing column 4 is set as a square structure, which can prevent the rotation between parts and has higher stability.

[0042] One first fixing groove 24 is provided on each of the two outer side walls of the first support leg 2, and two corresponding second fixing grooves 34 are provided in the second groove 31. Two limiting strips 33 are provided, the second fixing groove 34 is arranged between the two limiting strips 33, and the first fixing groove 24 is arranged between the two limiting grooves 23. The depths of the first fixing groove 24 and the second fixing groove 34 are both smaller than the depth of the limiting groove 23, which can save costs and prevent the fixing column 4 from falling off due to vibration or other reasons during use. The length of the fixing column 4 is less than or equal to the depth of the first fixing groove 24 or the second fixing groove 34, and the end face area of the end of the fixing column 4 located in the groove can be smaller than the cross-sectional area corresponding to the cavity, improving the assembly efficiency.

[0043] During installation, the first groove 21 and the second groove 31 are butted, the limiting strip 33 is aligned with the corresponding limiting groove 23, and the first support leg 2 is pressed to press the limiting post into the limiting groove 23. Then, the fixing column 4 is pressed into the cavity enclosed by the first fixing groove 24 and the second fixing groove 34, so that the first support leg 2 and the second support leg 3 are press-fitted through the fixing column 4, increasing the extrusion force to increase the frictional resistance and making the connection between the first support leg 2 and the second support leg 3 more stable. Finally, the rotating part 6 is installed to complete the assembly.

[0044] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same parts are denoted by the same reference numerals. Therefore: All equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
