Abstract
The utility model discloses an elastic pin type buckled leg tube device. The device comprises a movable leg. A leg leaning connection block matched with a leg leaning fixing block in a fixed leg is arranged on a transverse bending position of the upper portion of the movable leg. The lower portion of the movable leg is provided with a buckled elastic pin matched with a leg leaning supporting block arranged on a transverse rod of the lower end of the fixed leg. The buckled elastic pin is connected with the movable leg through a compression spring and a spring cushion block arranged in a supporting block connecting rod which is arranged on the movable leg. The elastic pin type buckled leg tube device enables the movable leg to insert the leg leaning connection block in a bicycle frame front supporting tube from the inner side and the outer side, and then the axis is rotated to buckle. The elastic pin type buckled leg tube device is reasonable in design, easy to install and detach, convenient, quick, easy, simple, safe and firm in matching, and good in stability.
Description
Technical field
This utility model relates to a kind of wheelchair parts, and specifically the bullet pin formula in a kind of wheelchair fastens lower limb pipe device.
