Abstract
The utility model provides a wheelchair capable of rapidly detaching a rear wheel, which comprises a wheelchair frame, wheels and a quick-detach shaft, wherein the wheelchair frame is provided with a mounting hole, the wheels are provided with shaft holes, the quick-detach shaft is penetrated in the mounting hole, the wheels are arranged in the wheelchair frame in the shaft holes, the quick-detach shaft comprises a shaft pipe, a moving shaft core, a return spring and a lock ball, the moving shaft core is arranged in the shaft pipe, the return spring is used to return the moving shaft core, and the lock ball is used to limit. The moving shaft core pushes the lock ball to upwardly move through a high block with the help of the elastic force of the return spring, thereby achieving a locking state. On the contrary, the shaft core is pushed to move, thereby urging a low block to be arranged below the lock ball. The lock ball falls on the low block with the help of own gravity to urge the lock ball to be completely collected in the shaft pipe, thereby achieving a lock state. The wheelchair capable of rapidly detaching the rear wheel solves the problems that wheels of wheelchairs are difficult to assemble and disassemble at present. The wheelchair capable of rapidly detaching the rear wheel enables the wheels and the wheelchair frame to be rapidly connected through the quick-detach shaft.
Description
Technical field
This utility model relates to a kind of wheelchair, more specifically refers to the wheelchair that a kind of trailing wheel can fast assembling-disassembling.
Background technology
Current wheelchair it adopt often rotating shaft by front and back nut or other locking mechanisms, wheel to be fixed on vehicle frame in the process of manufacturing, obviously in the process of manufacturing, need multiple parts to process, increase cost of labor, and too loaded down with trivial details in the process of assembling, be unfavorable for Reducing Cost in Enterprises, and patient when in use can not quick-replaceable wheel, causes a lot of inconvenience.
Summary of the invention
This utility model main purpose be to solve current wheelchair wheel assembling difficulty, dismantle difficult problem, the wheelchair that a kind of trailing wheel can fast assembling-disassembling is provided, it can be connected wheel fast by quick detach axle with wheelchair frame.
Another object of the present utility model is to provide a kind of cheap for manufacturing cost, simple in structure, wheelchair of being convenient for changing wheel.
The technical solution adopted in the utility model is: the wheelchair that a kind of trailing wheel can fast assembling-disassembling, comprise wheelchair frame, wheel and quick detach axle, wherein, this wheelchair frame offers installing hole, this wheel is provided with axis hole, this quick detach axle cross-under is at this installing hole, in this axis hole, this wheel is arranged in this vehicle frame, this quick detach axle comprises central siphon, be arranged on the sliding shaft core of this central siphon inside, for the back-moving spring of this sliding shaft core reset and for spacing locking ball, wherein, the end of this central siphon is provided with the accommodating hole for accommodating this locking ball, this locking ball is placed in this accommodating hole, this sliding shaft core is provided with for promoting this locking ball and stretches out the high-order piece outside central siphon, for the pushing block of accommodating the low level piece of this locking ball retraction central siphon inside and compressing for promoting back-moving spring, one end of this back-moving spring contacts with the inwall of this central siphon, the other end of this back-moving spring contacts with this pushing block.
The technical solution adopted in the utility model is: this utility model structurally comprises wheelchair frame, wheel and quick detach axle, wherein, this wheelchair frame offers installing hole, this wheel is provided with axis hole, this quick detach axle cross-under is at this installing hole, in this axis hole, this wheel is arranged in this vehicle frame, this quick detach axle comprises central siphon, be arranged on the sliding shaft core of this central siphon inside, for the back-moving spring of this sliding shaft core reset and for spacing locking ball, wherein, the end of this central siphon is provided with the accommodating hole for accommodating this locking ball, this locking ball is placed in this accommodating hole, this sliding shaft core is provided with for promoting this locking ball and stretches out the high-order piece outside central siphon, for the pushing block of accommodating the low level piece of this locking ball retraction central siphon inside and compressing for promoting back-moving spring, one end of this back-moving spring contacts with the inwall of this central siphon, the other end of this back-moving spring contacts with this pushing block.Quick detach axle is by after wheel and wheelchair frame assembling, sliding shaft core promotes locking ball upward displacement by back-moving spring elastic force by high-order piece, reach locking state, wheel and wheelchair frame are connected firmly, on the contrary, promote sliding shaft core and move, impel low level piece be positioned at locking ball under, locking ball, by the gravity of self, drops on this low level piece and impels locking ball to be housed in central siphon inside completely, reaches the state of release.It can be connected wheel fast by quick detach axle with wheelchair frame, the wheel that solves current wheelchair assembles difficulty, dismantles difficult problem, and it can be connected wheel fast by quick detach axle with wheelchair frame.
