Detailed Description
The rotary sofa chassis mechanism of the present invention will be further described with reference to fig. 1 to 3.
The rotary sofa chassis mechanism is characterized in that: the device comprises a chassis 1, a support shaft 2, a positioning sleeve 3, a mounting rack 4 and a bearing group. The supporting shaft 2 is fixed on the chassis 1 in a vertical state, namely the supporting shaft 2 is of a hollow tubular structure, and the lower end of the supporting shaft 2 is fixed on the central position of the chassis 1 through a bolt. The upper end of the locating sleeve 3 is fixed on the lower surface of the mounting frame 4 through a bolt and sleeved on the support shaft 2. The bearing group includes upper bearing 6 and lower bearing 5, upper bearing 6 is installed between the upper end of back shaft 2 and the lower surface of mounting bracket 4 or the upper end of position sleeve 3, and in this embodiment, upper bearing 6 is installed between the lower surface of mounting bracket 4 and the upper end of back shaft 2, lower bearing 5 is installed between the middle part of back shaft 2 and the lower extreme of position sleeve 3 to form the rotary type structure of mounting bracket 4 and position sleeve 3.
Specifically, the mounting frame 4 includes a bottom plate 42 and two support rods 41 fixed to the upper surface of the bottom plate 42 by bolts, and the support rods are provided with connection holes for assembling the bottom frame of the sofa.
The upper end position of the supporting shaft 2 is provided with an upper step 21, the lower surface of the bottom plate 42 is provided with a limit step 421 at the corresponding position, the upper end of the upper bearing 6 is abutted against the limit step 421 of the mounting frame 4, and the lower end is supported on the upper step 21. The middle part of the supporting shaft 2 is provided with a lower step 22, the lower end of the positioning sleeve 3 is provided with an inward extending inner flange, the inner flange is provided with an inner step 31, the upper end of the lower bearing 5 is abutted against the lower step 22, and the lower end of the lower bearing is supported on the inner step 31 of the positioning sleeve 3. The upper bearing 6 and the lower bearing 5 are both plane bearings. Thereby achieving a stable rotation function of the mounting bracket 4 with respect to the support shaft 2 and the chassis 1.
The middle part of the chassis 1 is raised upwards. Under this structure, only the marginal position of chassis 1 supports on subaerial, and all the other positions on chassis 1 are kept apart with ground, can show the stationarity that promotes chassis 1 and put subaerial, can also be convenient for chassis 1's removal simultaneously.
In order to further improve the stability of the support shaft 2 on the chassis 1, a positioning groove is formed in the center of the chassis 1, the lower end of the support shaft 2 is matched in the positioning groove, and then the support shaft is fixed by bolts.
Based on the structure, when the sofa is used, the sofa is fixed on the supporting rod 41 through the bolts, and the mounting frame 4 can perform stable circumferential rotation relative to the chassis 1 and the supporting shaft 2 through the matching among the positioning sleeve 3, the bearing group and the supporting shaft 2, so that the orientation adjustment of a user in a sitting posture state is facilitated, and the comfort of the user is improved.
