Abstract
The utility model discloses a kind of plum blossom 12 jiao of one word axle shelves stud, comprise head, screw rod, axle shelves and nut, described head comprises the plum blossom bihexagonal head being located at outside successively, be located at the annular radial projection at middle part and be located at the connecting head of inner side, the external diameter of described plum blossom bihexagonal head is greater than the external diameter of connecting head and the maximum outside diameter of plum blossom bihexagonal head, the center, outer end of described plum blossom bihexagonal head is provided with the flat head that can match with a word spanner, described axle shelves are provided with internal thread, described axle shelves coordinate with screw flight, with the shaft shoulder on described axle shelves, the described shaft shoulder coordinates with screw flight, the described shaft shoulder is equal with the upper-end surface of axle shelves.Its advantage is: make the single part energy repair and replacement of universal wheels, cost low, universal wheels can be made normally to work.
Description
Technical field
The utility model relates to technical field of fastening, is specifically a kind of plum blossom 12 jiao of one word axle shelves stud be arranged on universal wheels.
Technical background
Universal wheels refers to that the support being arranged on castor wheel can rotate by horizontal 360-degree in dynamic load or static load.Current whole universal wheels is non-removable, i.e. universal wheels rivet or be welded and fixed, and makes universal wheels cannot single part repair and replacement under deterioration extent at certain part, wholely can only change, makes maintenance cost high like this.If adopt existing plain bolt to be assembled by universal wheels, then can compress the ball up and down of universal wheels, and universal wheels cannot rotate by normal 360 horizontal 360-degrees.
Model utility content
The technical problems to be solved in the utility model is, provides a kind of and makes plum blossom 12 jiao of one word axle shelves stud that the single part energy repair and replacement of universal wheels, cost are low, universal wheels can be made normally to work.
For solving the problem, the technological scheme that the utility model provides is: comprise head, screw rod, axle shelves and nut, described head comprises the plum blossom bihexagonal head being located at outside successively, be located at the annular radial projection at middle part and be located at the connecting head of inner side, the external diameter of described plum blossom bihexagonal head is greater than the external diameter of connecting head and the maximum outside diameter of plum blossom bihexagonal head, the center, outer end of described plum blossom bihexagonal head is provided with the flat head that can match with a word spanner, described axle shelves are provided with internal thread, described axle shelves coordinate with screw flight, with the shaft shoulder on described axle shelves, the described shaft shoulder coordinates with screw flight, the described shaft shoulder is equal with the upper-end surface of axle shelves.
Also be provided with polished rod between described screw rod and connecting head, the external diameter of described polished rod is less than the external diameter of connecting head.
The thickness of described connecting head and the consistency of thickness of annular radial projection.
After adopting above structure, the utility model compared with prior art, has the following advantages: because the annular radial projection being located at middle part can ball on axial limiting universal wheels, and you can normally roll to ensure ball; Again owing to adopting stud to fix, be removable connection, make the single part energy repair and replacement of universal wheels, cost low, universal wheels can be made normally to work, can rotate by normal 360 horizontal 360-degrees.Again because the center, outer end of described plum blossom bihexagonal head is provided with the flat head that can match with a word spanner, can also be moved by a word spanner like this, easy to use.
