Along with improving constantly of people's living standard, perambulator, perambulator have been come into usual popular family life, in order to reach use, storage purpose convenient to both, a lot of perambulators, perambulator have adopted wheel to install and remove structure fast, so that the user when not using, can dismantle car body, be convenient for carrying, occupy the space, room simultaneously less, convenient storage; In addition, concerning maker, distributor, such structure, on the one hand instant packed, transportation and storage can reduce traffic cost on the other hand effectively.Existing technology is to reach the technical scheme that this purpose adopts to be: wheel is sleeved on spacing plush copper one end of tool on the wheel shaft, the wheel shaft other end has the pin-and-hole of vertical axle axial, be plugged among the ccontaining cavity of wheel seat when wheel shaft tool pin-and-hole one end after, utilize one one end to tie up to latch on the wheel seat and pass through hole on the ccontaining cavity wall and insert among the wheel shaft pin-and-hole with a rope, thereby to wheel, wheel shaft positioning and fixing in addition.It still adopts latch, pin-and-hole location structure, contraposition trouble, operation inconvenience; Latch only ties up on the wheel seat with a rope, loses because of the rope fracture easily; Latch does not have the device of withholding, and moves up and down in pin-and-hole easily, runs into place with a varied topography, uneven, may deviate from from pin-and-hole, causes safety misadventure.So its mounting or dismounting structure is also unreasonable, operates easyly inadequately, safety performance has much room for improvement.
Summary of the invention
It is convenient fast and the fast disassembly type wheel mount fixing structure of safety and firmness that technical problem to be solved in the utility model provides a kind of simple in structure, mounting or dismounting.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this kind fast disassembly type wheel mount fixing structure, include wheel seat that is fixed on the vehicle frame and the wheel shaft that is connected wheel, wheel shaft and wheel seat are socket connections, it is characterized in that wheel shaft inserts that the end in the ccontaining cavity is provided with annular groove in the wheel seat, and pass on the ccontaining cavity wall that through hole perpendicular to ccontaining cavity snaps in annular groove on the wheel shaft and positioning and fixing in addition by the latch in the blocking device of installing on wheel seat.
Described blocking device is made of spring, spanner and latch, wherein latch is inlayed and is fixed on spanner and is integral, spring one end is fixed on the latch, the other end is assemblied on the corresponding shoulder of wheel seat, whole blocking device then insert in the wheel block hole by latch ends and the other end by the spanner elastic deformation pack into position in the chute of wheel seat fixing.
Bulge loop in push pedal constitutes described spanner by push pedal and vertical fixing, and bulge loop inner hole section shape is corresponding with the latch cross-sectional plane, bulge loop can be with the push pedal global formation structure, also can separate molding structure, be spirally connected again or be adhered in the push pedal.
Described wheel seat has cross section and the corresponding ccontaining cavity of wheel shaft tool groove ends in one, have cross section and latch cross-sectional plane in one on the ccontaining cavity wall accordingly and perpendicular to the through hole of ccontaining cavity, described wheel seat also has a floor, floor has a blocking device storage tank corresponding to the position of through hole, the top of this groove is the spanner positioning groove, there are the shoulder that limits the spring motion, the limiting groove of restricted spring in bottom and latch side travel in the middle part of storage tank.
Compared with prior art, advantage of the present utility model is: 1, simple in structure, mounting or dismounting are convenient quick, and latch can snap in annular groove automatically after wheel shaft inserted wheel seat, avoided latch, pin-and-hole structure to need the problem of careful contraposition; 2, safety and firmness, owing to adopted the spring buckle pressure device, latch has had auto-reset function, can fastening safely and effectively wheel shaft.
