Detailed Description
As shown in fig. 1-5, the utility model relates to a self-locking mechanism of a rocker of a wheelchair; comprises a main body 1, a self-locking bracket 2 and a rocker 3.
The middle part of the self-locking support 2 is provided with a through groove 21, two side walls of the through groove 21 are provided with guide grooves 22, the guide grooves 22 are arc-shaped grooves, the tail end of each guide groove is provided with an upward oblique clamping groove 23, the self-locking support 2 is fixed on the top surface of the main body 1, and the through groove 21 of the self-locking support 2 is communicated with the inner cavity of the main body 1;
the rocker 3 extends into the inner cavity of the main body 1, the end part of the extending end of the rocker 3 is hinged on the main body 1, and the middle part of the rocker 3 is connected in the through groove 21 of the self-locking bracket 2 in a sliding way and can be clamped in the clamping groove 23.
The rocker 3 comprises a rod body 31, a movable handle 32, a movable sleeve 33, a handle spring 34 and a clamping shaft 35; the middle part of the rod body 31 is provided with a small sliding groove 311 which is arranged along the axial direction, and the lower end of the rod body 31 is provided with a transverse hole 312 which is used for being sleeved with a rocker rotating shaft; the middle part of the clamping shaft 35 is vertically fixed on the movable sleeve 33 and movably penetrates in the small sliding groove 311 of the rod body 31, and the outer end of the clamping shaft 35 is connected in the guide groove 22 of the self-locking bracket 2 in a sliding manner; the movable handle 32 is fixed at the upper end of a movable sleeve 33, the movable sleeve 33 is movably sleeved at the upper part of the rod body 31, and a handle spring 34 is arranged between the movable sleeve 33 and the upper end surface of the rod body 31.
