DETACHABLE UNIVERSAL WHEEL

Abstract (containing automatically inserted reference signs) The present application discloses a detachable universal wheel (3), including an angle-wrapping part, a wheel carrier (2), a wheel (3) fixed in the wheel carrier (2), a stucking part, a fixed shaft (5), and a locking cap (6). The stucking part including a protruding edge (7) has the rotary connection with the bottom of the angle-wrapping part, and the protruding edge (7) has a couple of inner through-holes (10, 8) with opposite position. At the top of wheel carrier (2) is provided with a fillister (9), which has the shape matching with that of the protruding edge (7) and has a couple of outer through-holes (10, 8) with opposite position. When the protruding edge (7) of the stucking part is placed into the fillister (9) which is at the top of the wheel carrier (2), the inner through-holes (10, 8) are in line with the outer through-holes (10, 8). The fixed shaft (5) can cross through the inner and outer through-holes (10, 8), with thread at its exposed end. The locking cap (6) can be screwed onto the exposed end of the fixed shaft (5) to achieve the aim of locking. Due to the structural math between the protruding edge (7) of the stucking part and the fillister (9) of the wheel carrier (2) and through the screwing and detaching of the fixed shaft (5) and locking cap (6), the detachable universal wheel (3) disclosed by the present application has simple and reliable structure and is convenient to be detached.
