Description
Technical Field
The utility model relates to a caster structure, in particular to a case caster structure.
Background
To facilitate pulling the luggage while traveling, casters are typically mounted to the luggage. The existing case caster mainly comprises a connecting seat, a rotating shaft, a supporting frame and wheels, wherein the wheels are arranged on the supporting frame, one end of the rotating shaft is fixed with the connecting seat, the other end of the rotating shaft is provided with an annular groove and is inserted into the supporting frame, the supporting frame can freely rotate relative to the rotating shaft, one side of the supporting frame penetrates a pin corresponding to the annular groove on the rotating shaft, and the pin is clamped with the rotating shaft, so that the rotating shaft is connected with the supporting frame and can rotate. The supporting frame and the connecting seat of the case caster are not detachable, and the wheels or the supporting frame can only be integrally replaced after being damaged, even the case is scrapped. In addition, because the supporting frame can not be disassembled, the luggage occupies a larger space when being stored and transported, and is not convenient enough to use.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a caster structure for a luggage, wherein a supporting frame and a connecting seat are detachable, so that parts are convenient to replace, the maintenance cost is reduced, and the storage space can be saved.
In order to solve the technical problem, the caster structure of the luggage comprises a connecting seat, a rotating shaft, a supporting frame and wheels, wherein the lower part of the supporting frame is connected with the wheels, the upper part of the supporting frame is connected with the connecting seat through the rotating shaft, a cavity with a side opening is formed in the connecting seat, a movable locking piece is arranged in the cavity, a spring is arranged at the end part of the locking piece and is positioned between the locking piece and the inner wall of the cavity, the other end of the locking piece is connected with a pressing block, a through hole for the rotating shaft to penetrate through is formed in the locking piece, a bayonet communicated with the through hole is formed in the side of the through hole, the opening direction of the bayonet is opposite to the direction of the spring, and an annular groove correspondingly matched with the bayonet is formed in the rotating shaft.
The pressing block is provided with a limiting frame at the end part, and the upper side and the lower side of the limiting frame are respectively provided with a triangular hook used for being clamped in the cavity opening, so that the limiting frame can be quickly disassembled and assembled.
The end of the locking piece is provided with a convex block, and the spring is sleeved on the convex block, so that the spring is well positioned, and the structure is more stable.
The middle part of the limit frame is provided with a central hole, and the end part of the pressing block is provided with a pressing head inserted into the central hole, so that the position of the pressing block is accurately limited, and the use is more reliable.
The connecting seat is provided with a sleeve for inserting and positioning the rotating shaft, so that the rotating shaft is easier to position, and the rotating shaft can be prevented from shaking to influence the use of a product.
The beneficial effects of the utility model are: in this kind of luggage truckle structure, adopt the cavity of connecting seat to set up mobilizable locking piece, through the through-hole on the locking piece and bayonet socket and the cooperation of pivot realize the locking of countershaft, make supporting rack and connecting seat dismantled and assembled, the renewal part of being convenient for reduces the maintenance cost, can save storage space moreover.
