Easy assembling and disassembling wheel component
The present disclosure provides an easy assembling and disassembling wheel component, including a wheel, a rotation shaft and an engaging member, wherein a mounting hole is disposed on a center of the wheel, an accommodating groove is disposed at one end of the rotation shaft, the engaging member is movably engaged in the accommodating groove and is swingable between a first position and a second position. When the engaging member is in the first position, the engaging member and the rotation shaft can pass through the mounting hole of the wheel; when the engaging member is in the second position, the rotation shaft is connected with and locked to the wheel. The easy assembling and disassembling wheel component according to the present disclosure has advantages of simple structure, quick and convenient assembling and disassembling. And, the present disclosure also provides five kinds of easy assembling and disassembling wheel components.
1 . A wheel component, comprising a wheel, a rotation shaft and an engaging member, wherein a mounting hole is disposed on a center of the wheel, an accommodating groove is disposed on one end of the rotation shaft, the engaging member is movably engaged in the accommodating groove and is swingable between a first position and a second position, when the engaging member is in the first position, the engaging member and the rotation shaft can pass through the mounting hole of the wheel; when the engaging member is in the second position, the rotation shaft is connected with and locked to the wheel,
wherein the engaging member has an elongated ring-shaped structure, an elongated hole is formed in a middle of the engaging member, an engaging region is disposed in a middle of the elongated hole, two arc-shape hole regions are formed on two lateral sides of the elongated hole, and an edge of the engaging member is in a corrugated structure to form the engaging region and has an elastic force, a connection portion is disposed in the accommodating groove and passes through the engaging member;
wherein, when the connection portion reaches the corrugated structure, the corrugated structure is elastically stretched and allows the connection portion to pass through;
wherein, when the connection portion passes over the corrugated structure, the corrugated structure springs back and the engaging region engages with the connection portion.
2 . The wheel component according to claim 1 , wherein the accommodating groove penetrates two lateral surfaces and an end surface of the rotation shaft, and a connection portion is disposed in the accommodating groove and passes through the engaging member.
3 . The wheel component according to claim 1 , wherein the first position is a position to which the engaging member is swung such that a length direction of the engaging member is the same as a central axis extension direction of the rotation shaft; the second position is a position to which the engaging member is swung such that the length direction of the engaging member intersects with the central axis extension direction of the rotation shaft and the engaging member presses against an edge of the mounting hole.
4 . The wheel component according to claim 1 , wherein an elongated hole is formed in the middle of the engaging member, an engaging region is disposed in the middle of the elongated hole, and the connection portion is engaged with the engaging region when the rotation shaft is locked on the wheel.
5 . The wheel component according to claim 2 , wherein the connection portion is a connection shaft.
6 . The wheel component according to claim 1 , further comprising a wheel cover for covering one side of the wheel to shield the engaging member; and a positioning rib for positioning the engaging member is disposed on an inner side of the wheel cover.
