[0027] Referring to Figure 1 and Figure 2 , the seat base comprises a base body 100 and a base foot 200.

[0028] The middle part of the base body 100 is provided with a mounting through hole 110, and the mounting through hole 110 is used for connecting with the air pressure rod.

[0029] The lower end of the base body 100 is provided with a plurality of plug-in grooves 120, and the groove opening of the plug-in groove 120 faces the lower part of the base body 100. The number of plug-in grooves 120 is set to be multiple, and the multiple plug-in grooves 120 are arranged circumferentially around the central axis of the base body 100.

[0030] Specifically, in the embodiment, the bottom end of the plug-in groove 120 is a semicylindrical arc surface structure, and in other embodiments, the bottom end of the plug-in groove 120 can also be provided with a planar structure, and the skilled in the art can select the shape of the bottom end of the plug-in groove 120 according to actual needs.

[0031] The number of base feet 200 is set to five, and the five base feet 200 are arranged equidistantly around the central axis of the base body 100. In other embodiments, the number of base feet 200 can also be set to four, six, or the like, and those skilled in the art can select the number of base feet 200 according to actual needs.

[0032] The number of base feet 200 is set to five, and the base feet 200 are arranged one-to-one with the plug-in grooves 120. The end of the base foot 200 is fixedly provided with a plug-in structure 210, which is used for being inserted into the plug-in groove 120. The plug-in structure 210 is inserted into the plug-in groove 120 from bottom to top to realize the connection of the base foot 200 and the base body 100.

[0033] The plug-in structure 210 is set to a cylindrical structure. The plug-in structure 210 and the base body 100 are provided with a locking structure 300, which includes a locking insert 310 and a locking slot 320. The locking insert 310 is fixedly arranged on the base foot 200, and the locking insert 310 and the plug-in structure 210 are arranged in the up-down direction. The locking slot 320 is opened on the base body 100, and the cross sections of the locking insert 310 and the locking slot 320 are both set to rectangles. The locking insert 310 and the locking slot 320 are in interference fit.

[0034] The plug-in structure 210 is set to a cylindrical structure, so that after the plug-in structure 210 is inserted into the plug-in groove 120, the base foot 200 can rotate relative to the base body 100, so that the locking insert 310 can be inserted into the locking slot 320. After the locking insert 310 is inserted into the locking slot 320, the interference fit of the locking insert 310 and the locking slot 320 can improve the connection strength of the base foot 200 and the base body 100, so that the base foot 200 and the base body 100 are not easy to move relative to each other.

[0035] In other embodiments, the locking insert 310 can be fixedly arranged on the base body 100, and the locking slot 320 can be opened on the base foot 200. Those skilled in the art can select the setting positions of the locking insert 310 and the locking slot 320 according to actual needs, so that the connection strength of the base foot 200 and the base body 100 is improved.

[0036] Specifically, in the present embodiment, the base foot 200 is provided with a weight-reducing hollow groove 220, and the groove opening of the weight-reducing hollow groove 220 is arranged downward. The downward arrangement of the groove opening of the weight-reducing hollow groove 220 can avoid dust from being deposited into the weight-reducing hollow groove 220, so as to avoid dust accumulation in the weight-reducing hollow groove 220.

[0037] In other embodiments, a cover plate can be arranged at the slot opening of the weight-reducing hollowed-out groove 220 to prevent small animals from entering the weight-reducing hollowed-out groove 220. When the cover plate is arranged at the slot opening of the weight-reducing hollowed-out groove 220, the slot opening of the weight-reducing hollowed-out groove 220 can be arranged upward or downward. Those skilled in the art can select whether to arrange the cover plate at the slot opening of the weight-reducing hollowed-out groove 220 and the orientation of the slot opening of the weight-reducing hollowed-out groove 220 according to actual needs.

[0038] Specifically, in the present embodiment, a plurality of reinforcing ribs 230 are arranged in the weight-reducing hollowed-out groove 220, and the plurality of reinforcing ribs 230 are uniformly distributed in the weight-reducing hollowed-out groove 220. Arranging the plurality of reinforcing ribs 230 in the weight-reducing hollowed-out groove 220 can improve the overall strength of the base foot 200.

[0039] Specifically, in the present embodiment, the reinforcing ribs 230 are arranged in a cross-shaped structure. Arranging the reinforcing ribs 230 in a cross-shaped structure can effectively improve the strength of the reinforcing ribs 230.

[0040] The base foot 200 is provided with a universal wheel connecting hole 240 at the end away from the base body 100. The universal wheel connecting hole 240 is used to connect with the connecting shaft of the universal wheel to achieve the installation of the seat base and the universal wheel.

[0041] The present scheme splits the seat base into the base body 100 and the plurality of base feet 200, so that the seat base can be transported to the downstream manufacturer in multiple parts. Compared with the integrated seat base, the seat base can effectively reduce the space occupied during transportation, reduce the transportation cost of the seat base, and facilitate the transportation of the seat base.

[0042] The preferred embodiments of the present application are described in detail above, but the present application is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
