Technical Field

The invention relates to the field of bags and suitcases, in particular to a detachable box wheel structure.

Background

In the current luggage industry, in order to solve the problem that luggage wheels of a luggage case are inconvenient to replace after being worn, people improve the structure of the luggage wheels and design detachable luggage wheels, namely, the luggage wheels with wheel shafts separable from wheel carriers, so that the purpose of replacing wheel groups below the wheel carriers is achieved.

The existing detachable box wheels are all formed by directly installing wheel shafts into wheel frames, and the limiting and fixing are realized by transversely matching hardware clamping sheets on the wheel frames with the wheel shafts, as described in Chinese patent publication No. CN 207285487U; the mounting mode can control the disassembly and assembly of the wheel set only by operating the hardware clamping piece, is very convenient, but in fact, a series of problems such as expansion with heat and contraction with cold of the wheel shaft made of metal materials cannot be overcome by the existing process, so that the wheel shaft and the wheel frame can be perfectly matched, namely the existing wheel shaft is mounted in the wheel frame and cannot be perfectly attached to the wheel frame, and a gap is always reserved between the top end of the wheel shaft and the inner wall of the cover plate of the wheel frame.

Just because the space between shaft and the wheel carrier, the shaft has the space of ascending activity in the wheel carrier, need know shaft and wheel carrier and realize spacing through the cooperation of the five metals card that transversely sets up and shaft, fall to the ground with the case wheel state vertical down, the shaft can atress produce the potential energy of ascending activity when the case wheel contacts with ground, the five metals card that transversely sets up just needs to bear this potential energy, like this when the case wheel falls to the ground certain number of times or the impact force that this potential energy produced is great, the five metals card on the wheel carrier just can warp the damage because of not bearing this potential energy.

Disclosure of Invention

In order to solve the above technical problems, an object of the present invention is to provide a detachable caster structure in which a wheel shaft is mounted to a caster frame so as to be able to be effectively attached without generating a gap.

In order to achieve the purpose, the technical scheme adopted by the invention is as follows: a detachable box wheel structure is characterized in that an inner wheel frame is arranged at one end of a wheel shaft, and the wheel shaft is movably connected with the wheel frame through the inner wheel frame.

Through adopting above-mentioned technical scheme, interior wheel carrier has overcome the shaft because of the process problem that the material leads to, has higher precision, can with the cooperation of wheel carrier zero clearance, has reached the purpose of effective laminating, interior wheel carrier is fixed to be set up on the shaft as an organic whole with it, the shaft passes through interior wheel carrier and wheel carrier cooperation swing joint, so just solved the problem that shaft and wheel carrier swing joint department do not laminate.

Preferably, the wheel frame is provided with a first through hole, and the inner wheel frame is connected with the first through hole in a matching manner.

Through adopting above-mentioned technical scheme, interior wheel carrier inserts first through-hole and is connected with it cooperation, and structural stability is higher under the parcel of first through-hole.

Preferably, a fixing structure is arranged in the first through hole.

Through adopting above-mentioned technical scheme, fixed knot constructs can to realize fixing to the inner wheel frame horizontal direction, prevents that it from the horizontal direction rotation in first through-hole.

Preferably, the wheel carrier is provided with a cover plate.

By adopting the technical scheme, the cover plate is a stopper arranged at the top end of the wheel carrier when the inner wheel carrier and the wheel carrier are matched, and no space for upward movement is reserved for the attachment of the inner wheel carrier and the cover plate.

Preferably, the cover plate is integrally formed with the wheel frame.

Through adopting above-mentioned technical scheme, apron and wheel carrier integrated into one piece have promoted the structural stability of apron.

Preferably, the wheel carrier is provided with a limiting mechanism.

Through adopting above-mentioned technical scheme, stop gear can carry out spacing fixed to the inner wheel carrier.

Preferably, the limiting mechanism is a limiting bayonet lock.

Through adopting above-mentioned technical scheme, because interior wheel carrier is different from the shaft, it need not the level with the wheel carrier cooperation and rotates, consequently also need not draw-in groove and the cooperation of five metals card through the loop type, only need set up spacing hole on the wheel carrier including, it is spacing to cooperate through spacing bayonet lock, and spacing bayonet lock is compared in its thickness of five metals card thicker, has higher structural stability.

Preferably, the limiting bayonet is provided with a torsion spring.

Through adopting above-mentioned technical scheme, under the effect of torsional spring, automatic re-setting can be realized to spacing bayonet lock.

Preferably, the limiting mechanism is of a threaded structure.

Through adopting above-mentioned technical scheme, interior wheel carrier passes through the screw thread with the wheel carrier and screws up, and it can have better connection stability.

Compared with the prior art, the invention has the advantages that: (1) the problem that the movable connection part of the wheel shaft and the wheel carrier is not attached is solved; (2) the cover plate and the wheel carrier are integrally formed, so that the structure stability is achieved.
