Description
Technical field
The utility model relates to perambulator accessory technical field, more particularly, relates to a kind of pushchair of quick dispatch.
Background technology
Existing pushchair is arranged on wheel shaft two ends.Pushchair center is provided with axle sleeve, and axle sleeve is provided with slotted eye, and axle ends is provided with annular positioning groove, during installation, axle ends annular positioning groove aims at slotted eye, utilizes the elastic wire of special shape structure to be buckled on the annular positioning groove of wheel shaft through slotted eye, wheel shaft is fixed.This structure, when needs Assembly &Disassembly wheel shaft, must be exerted oneself or pull elastic wire by instrument, and make it buckle or depart from the annular positioning groove of wheel shaft, wheel shaft just can be installed or be removed, and operates extremely inconvenient, and requires great effort very much.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of structure simple, easy to operate, can the pushchair of Fast Installation or quick-detachment.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A pushchair for quick dispatch, comprises wheel and wheel shaft, it is characterized in that, described wheel is provided with the anchor fitting for fixing wheel shaft, and wheel shaft is provided with annular positioning groove; Described anchor fitting comprises positioning shaft sleeve, pressing piece and locating dowel pin, and pressing piece is in positioning shaft sleeve, is provided with retracing spring between pressing piece and positioning shaft sleeve; Described positioning shaft sleeve sidewall offers the chute vertical with wheel shaft axis direction, and described pressing piece sidewall offers skewed slot; Described locating dowel pin is through chute, skewed slot; Described lateral wheel center is provided with the groove for fixing device for installing, and bottom portion of groove offers the through hole passed for wheel shaft.
By pressing described press section, making skewed slot drive locating dowel pin to move in chute, thus locating dowel pin skidded off or slips into the annular positioning groove on wheel shaft.
Further, described anchor fitting is provided with protecting sleeve, and protecting sleeve is cylindrical tube shape, and protecting sleeve is set in outside anchor fitting, prevents described locating dowel pin from having departed from chute and skewed slot.
Further, described chute and skewed slot are strip.
Further, described chute, skewed slot and locating dowel pin quantity are a pair, are all in wheel shaft both sides.
During assembling, press pressing piece, two locating dowel pins are under skewed slot drives, the spacing of two locating dowel pins becomes large, wheel shaft is inserted positioning shaft sleeve and makes the annular positioning groove of wheel shaft aim at locating dowel pin, then unclamping pressing piece, under the effect of retracing spring, pressing piece resets, and locating dowel pin is buckled in the annular positioning groove of wheel shaft, and now namely wheel shaft is firmly fixed.
During dismounting, as long as press pressing piece, two locating dowel pins are under skewed slot drives, and the spacing of two locating dowel pins becomes large, namely relieves the buckle of locating dowel pin to the annular positioning groove of wheel shaft, thus, wheel shaft or namely wheel unloads very easily.
The utility model beneficial effect is against existing technologies: by pressing described pressing piece, locating dowel pin on anchor fitting is slided between chute, skewed slot, thus realize the annular positioning groove of locating dowel pin buckle or disengaging wheel shaft, facilitate the installation or removal of vehicle, greatly reduce labour power, improve production efficiency, user also easily, rapidly can install or remove wheel.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the schematic diagram that Fig. 1 part decomposes;
Fig. 3 is the schematic diagram of anchor fitting locking wheel Spindle Status in the utility model preferred embodiment.
Detailed description of the invention
As Figure 1-3, the pushchair of the quick dispatch in the utility model preferred embodiment, comprises wheel 1 and wheel shaft 2, it is characterized in that, described wheel 1 is provided with the anchor fitting 3 for fixing wheel shaft 2, and wheel shaft 2 is provided with annular positioning groove 21; Described anchor fitting 3 comprises positioning shaft sleeve 31, pressing piece 32 and locating dowel pin 33, and pressing piece 32 is in positioning shaft sleeve 31, is provided with retracing spring 34 between pressing piece 32 and positioning shaft sleeve 31; Described positioning shaft sleeve 31 sidewall offers the chute 311 vertical with wheel shaft 2 axis direction, and described pressing piece 32 sidewall offers skewed slot 321; Described locating dowel pin 33 is through chute 311, skewed slot 321; Described wheel 1 outer side center is provided with the groove 11 for fixing device for installing 3, offers the through hole 12 passed for wheel shaft 2 bottom groove 11.
By pressing described press section 32, make skewed slot 321 drive locating dowel pin 33 to move in chute 311, thus make locating dowel pin 33 skid off or slip into annular positioning groove 21 on wheel shaft 2.
Described anchor fitting 3 is provided with protecting sleeve 4, and protecting sleeve 4 is in cylindrical tube shape, and protecting sleeve 4 is set in outside anchor fitting 3, prevents described locating dowel pin 33 from having departed from chute 311 and skewed slot 321.
Described chute 311 and skewed slot 321 are strip.
Described chute 311, skewed slot 321 and locating dowel pin 33 quantity are a pair, are all in wheel shaft 2 both sides.
During assembling, press pressing piece 32, two locating dowel pins 33 are under skewed slot 321 drives, the spacing of two locating dowel pins 33 becomes large, wheel shaft 2 is inserted positioning shaft sleeve 31 and makes the annular positioning groove 21 of wheel shaft 2 aim at locating dowel pin 33, then unclamping pressing piece 32, under the effect of retracing spring 34, pressing piece 32 resets, and locating dowel pin 33 is buckled in the annular positioning groove 21 of wheel shaft 2, and now namely wheel shaft 2 is firmly fixed.
During dismounting, as long as press pressing piece 32, two locating dowel pins 33 are under skewed slot 321 drives, and the spacing of two locating dowel pins 33 becomes large, namely relieves the buckle of the annular positioning groove 21 of locating dowel pin 33 pairs of wheel shafts 2, thus, wheel shaft 2 or namely wheel 1 unloads very easily.
The foregoing is only preferred embodiment of the present utility model, be not used for limiting practical range of the present utility model; Namely all equivalents done according to right of the present utility model, are right of the present utility model and cover.
