[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] Example 1 like Figure 1-4 As shown, this utility model provides a technical solution: an elastic locking type automatic return swivel chair chassis, including a bottom mounting plate 1, a support shaft 2 movably connected inside the bottom mounting plate 1, a support rod 4 fixedly connected to the outer wall of the bottom mounting plate 1, and a connecting assembly 3 disposed on one side of the bottom mounting plate 1. The connecting assembly 3 includes a rotating mechanism 31 disposed between the bottom mounting plate 1 and the support shaft 2. An auxiliary mechanism 32 is disposed at the end of the support rod 4. The rotating mechanism 31 includes a mounting ring fixedly connected to the upper part of the bottom mounting plate 1. 311, The mounting ring 311 has an inner groove 312 inside, and a pressure post 313 is movably connected inside the inner groove 312. A first spring 314 is fixedly connected to the inner wall of the inner groove 312. A connecting ring 315 is fixedly connected to the outer wall of the support shaft 2. A pressure groove 316 is opened on the outer wall of the connecting ring 315. A mounting block 317 is fixedly connected to the bottom of the support shaft 2. A torsion spring 318 is fixedly connected to the upper part of the mounting block 317. A damping ring 319 is fixedly connected inside the bottom mounting plate 1, and the damping ring 319 is in contact with the outside of the support shaft 2.

[0017] In this embodiment, one end of the first spring 314 is fixedly connected to the pressing post 313, the outer diameter of the connecting ring 315 is adapted to the inner diameter of the mounting ring 311, the pressing end of the pressing post 313 is convex, and the pressing end of the pressing post 313 is adapted to the pressing groove 316. Through the cooperation of the mounting ring 311, the inner groove 312, the pressing post 313, the first spring 314, the connecting ring 315, the pressing groove 316, the mounting block 317, and the torsion spring 318, the seat can be automatically reset without manual reset, which increases the applicability of the device.

[0018] Furthermore, the top of the torsion spring 318 is fixedly connected to the bottom of the bottom mounting plate 1.

[0019] When using this device, the top of the support shaft 2 is first installed with the seat. When people sit on the seat, gravity pushes the support shaft 2 downward, causing the connecting ring 315, which is fixed to the outer wall of the support shaft 2, to move downward synchronously. The connecting ring 315 then enters the mounting ring 311. When the seat rotates, the first spring 314, under its elastic force, causes the pressing post 313 to press against the pressing groove 316, which helps to position the angle after rotation, increasing the applicability of the device. When the support shaft 2 moves downward, the mounting block 317, which is fixed to the bottom of the support shaft 2, moves downward synchronously, causing the torsion spring 318 to deform. When people move away from the seat, the torsion spring 318 causes the seat to return to its original position. With the cooperation of the damping ring 319, excessive rotation of the seat can prevent a deviation in the return position.

[0020] Example 2 Based on Embodiment 1, a preferred embodiment of the elastic locking point type automatic return swivel chair chassis provided by this utility model is as follows: Figures 1 to 4 As shown: The auxiliary mechanism 32 includes a groove 321 formed at the bottom of the support rod 4, an installation groove 322 formed at the bottom end of the support rod 4, an installation column 323 movably connected inside the installation groove 322, a movable wheel 324 installed at the bottom of the installation column 323, a third spring 325 fixedly connected to the inner wall of the installation groove 322, and a damper 326 fixedly installed on the inner wall of the auxiliary mechanism 32.

[0021] In this embodiment, the bottom end of the third spring 325 is fixedly connected to the mounting post 323, and there are five support rods 4, which are evenly distributed on the outside of the bottom mounting plate 1. Through the cooperation of the groove 321, mounting slot 322, mounting post 323, moving wheel 324, third spring 325, and damper 326, a shock absorption effect can be achieved, thereby providing protection for the device. Furthermore, each moving wheel 324 is individually shock-absorbing, which can prevent a single moving wheel 324 from getting stuck during movement and causing the seat to tip over. In addition, the moving wheel 324 is a silent wheel, which is more suitable for office spaces.

[0022] Furthermore, the bottom end of the damper 326 is fixedly connected to the mounting post 323, and a sound-absorbing pad is fixedly connected to the outside of the rim of the moving wheel 324.

[0023] When the device is in use, the instantaneous pressure when a person sits on the seat causes the third spring 325 to deform. With the cooperation of the damper 326, this deformation provides shock absorption, preventing damage to the moving wheels 324 due to the instantaneous pressure and thus extending the service life of the swivel chair. Furthermore, when the swivel chair is in motion and a single moving wheel 324 comes into contact with an obstacle, such as a power cord, the individual shock absorption of each moving wheel 324, combined with the support of the moving wheels 324 in other positions, allows the moving wheel 324 that encounters the obstacle to move upwards under the action of the third spring 325. This prevents the moving wheel 324 from jamming and causing the swivel chair to tip over. At the same time, the groove 321 makes the material of the support shaft 2 lighter, and the moving wheels 324 are silent wheels, making the device more suitable for office environments and further increasing its applicability.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
