Abstract
The utility model relates to a clamp spring free universal wheel. The structure of the clamp spring free universal wheel comprises a wheel seat, a foot stand and a wheel, wherein the wheel is connected with the foot stand by a connecting shaft; the clamp spring free universal wheel is characterized in that the foot stand is connected with the wheel seat by a vertical shaft; the upper part of the vertical shaft is fixedly connected with the wheel seat; annular recesses are formed in the middle lower part of the vertical shaft; a vertical shaft inserting hole is formed in the foot stand; at least two symmetric projections are arranged in the inserting hole; the projections are adaptive to the recesses on the vertical shaft in position and shape; the projections can be clamped into the annular recesses on the vertical shaft; the projections in the inserting hole are continuously annular; the projections in the vertical shaft inserting hole of the foot stand are integrated with the foot stand; and through special equipment, the vertical shaft is pressed into the foot stand, so that the annular projections in the foot stand are clamped into the annular recesses of the vertical shaft; therefore, the foot stand cannot fall off and can also flexibly rotate for 360 degrees.
Description
Technical field
The utility model relates to a kind of universal wheel component, relates in particular to the cardan wheel of case and bag.
Background technology
Existing universal wheel component comprises holder, support, and wheel, wheel is connected with support through a transverse axis; The holder with support between be connected through a vertical pivot, the vertical pivot notch has the axle mounting hole on the support, mounting hole is connected through jump ring with vertical pivot; Or pass the vertical pivot notch simultaneously with a pin that crosses support, such structure more complicated uses noise big, rotates dumb; The assembling difficulty, time-consuming waste wood, service life is shorter.
Summary of the invention
The problem that the utility model solves provides a kind of simple in structure, and productive costs is low, and is easy to assembly, and work efficiency is high, rotates flexibly, and is quiet, shock-resistant, the cardan wheel of long service life.
In order to solve the problems of the technologies described above, technical scheme of the present invention is following:
No circlip type cardan wheel, its structure comprises wheel seat, foot rest; Wheel, wheel is connected with foot rest through an adapter shaft, it is characterized in that: connect through a vertical pivot between said foot rest and the wheel seat; Captive joint with wheel seat in the top of said vertical pivot, the vertical pivot middle and lower part is provided with annular groove, and foot rest inside is provided with the vertical pivot jack; The convexity that has two symmetries in the jack at least, the groove on protruding position, shape and the vertical pivot adapts, and convexity can snap in the annular groove on the vertical pivot.
Adopt such structure through specialized equipment vertical pivot to be compressed into foot rest, the annular protrusion in the foot rest is snapped in the annular groove of vertical pivot, foot rest just can't come off, and can rotate flexibly by 360 degree again, has simplified the quantity of assembly, and easy for installation, has practiced thrift cost.
Convexity in the further preferred jack is continuous annular.
Further convexity and the foot rest in the foot rest vertical pivot jack is one.
Further said vertical pivot bottom end face curved surface shape spherical in shape.
Be provided with circular iron wash between further said vertical pivot bottom end face and foot rest contact surface.
Adopt such structure not only to simplify the structure of universal wheel component, practiced thrift cost, easy for installation, production efficiency is high, and is quiet, and shock-resistant, rotates flexibly.
Description of drawings
Fig. 1 is this later-model front view,
Fig. 2 is the front view of vertical pivot.
The specific embodiment
Below in conjunction with embodiment the utility model is elaborated.
Among the figure one, 1 is wheel seat, and 2 is foot rest, and 3 is wheel, and 4 is adapter shaft, and 5 is protruding, and 6 is vertical pivot, and 7 is packing ring, and 8 is the groove of vertical pivot, and 9 is the boss of vertical pivot, and 10 is the upper surface of boss, and 11 is the lower surface of boss.
Wheel seat 1 links together through vertical pivot 6 with foot rest 2, in the latter half of foot rest 2 stuck point 5 of the evagination of two symmetries is arranged, and foot rest is fixed together through adapter shaft 4 and wheel 3.Fluted 8 in the latter half of vertical pivot 6, protruding 5 can snap in the draw-in groove 8; Protruding quantity is two stuck points of symmetry at least, can also be continuous annular, and stuck point and foot rest are integrally formed; The first half at vertical pivot has a boss 9, and the upper table surface of boss 9 matches with wheel seat 1, the following table 11 of the boss 9 on the vertical pivot and upper table surface 10 upper ends and wheel seat 1; There is big gap foot rest 2 upper ends; The friction force of whole universal wheel component is only occurred between vertical pivot bottom end face and foot rest 2 lower surfaces, avoided foot rest 2 and wheel seat 1, the friction force between foot rest 2 and the vertical pivot following table 11 influences the rotation alerting ability of universal wheel component.
Vertical pivot is pressed in the foot rest 2 through specialized equipment, utilizes convexity with the cooperation of groove wheel seat and foot rest clasp to be in the same place, and foot rest neither comes off and can rotate flexibly.Adopt such structure to practice thrift productive costs, greatly reduce noise, improved work efficiency again.
Between vertical pivot and the contacted end face of wheel seat, be placed with ring washer, make riveted joint more firm.The end face that contacts with foot rest at the vertical pivot bottom end face is placed with rounded washers, and rounded washers can play wear-resistant, impact-resistant effect, and simultaneously, area of contact is littler between vertical pivot and the packing ring, rotates more flexible.
Aforesaid embodiment only is used to explain how the utility model can be realized, and unrestricted the utility model is only realized with aforesaid way.Those skilled in the art the utility model technical scheme are carried out changes such as size, length according to common practise or material is replaced the protection domain that still belongs to the utility model.
Claims (6)
1. do not have the circlip type cardan wheel, its structure comprises wheel seat, foot rest; Wheel, wheel is connected with foot rest through an adapter shaft, it is characterized in that: connect through a vertical pivot between said foot rest and the wheel seat; Captive joint with wheel seat in the top of said vertical pivot, the vertical pivot middle and lower part is provided with annular groove, and foot rest inside is provided with the vertical pivot jack; The convexity that has two symmetries in the jack at least, the groove on protruding position, shape and the vertical pivot adapts, and convexity can snap in the annular groove on the vertical pivot.
