The specific embodiment

For having a better understanding and awareness the purpose of this utility model, feature and effect, below coordinate accompanying drawing to describe in detail as rear:

At first, first refer to Fig. 1, shown in Fig. 2, a kind of castor, it comprises: an assembled base 10, one wheel body 20 and two wheel covers 30, one assembled base 10 cooperation groups are provided with

support

11, and 11, assembled base 10 and support dispose bearing unit (figure does not mean), make the mutual swing start of 11 energy of assembled base 10 and support, support 11 is extended with two parallel in conjunction with support arm 111 again, and be equipped with combined hole 112, separately provide screw piece 12 and nut 13, one wheel body 20 coordinate be mounted on support two in conjunction with 111 of support arms, and be equipped with combination bore 21 in the corresponding combined hole 112 of centre, and combination bore 21 internal configurations have bearing part 22, two wheel covers 30 are disposed at respectively wheel body 20 both sides, this two wheel cover 30 has respectively the involution section 31 that a cooperation is covered in wheel body 20 sides, these involution section 31 outer peripheral edges are bent with stopper 311 toward wheel body 20 directions, and be equipped with axis hole 312 in center, and involution section 31 inwalls are to convex with fit fin 313 by axis hole 312 places, separately provide a spacing ring 32 and be sheathed on fit fin 313, involution section 31 outsides are combined with limiting section 33 again, the corresponding support 11 of this limiting section 33 be formed with respectively position-limited trough 331 in conjunction with support arm 111, and be equipped with perforation 332 in the inwall contraposition.

The composition of its structure, refer to again Fig. 1, Fig. 2, shown in Fig. 3, this two wheel cover 30 is incorporated into wheel body 20 both sides, and wheel cover 30 is the corresponding cappings of combination bore 21 with axis hole 312 with the wheel body 20 at involution section 31 centers, and be arranged with spacing ring 32 in involution section 31 inwalls and 20 of wheel bodys by fit fin 313, to limit the distance of 20 of wheel cover 30 and wheel bodys, separately prevent that wheel cover 30 from producing unstable situation of rocking, last again wheel body 20 is coordinated be mounted on assembled base 10 in conjunction with 111 of support arms, and related the limiting section of wheel cover 30 33 is placed in conjunction with on support arm 111 with position-limited trough 331, separately make the axis hole 312 of wheel cover 30, the combination bore 21 of perforation 332 and wheel body 20 forms the contraposition communicating state with the combined hole in conjunction with support arm 111 112, screw piece 12 can be arranged in conjunction with support arm 111 thus, 30 of wheel body 20 and wheel covers, provide again nut 13 screw lock packing relative to screw piece 12, make two wheel covers 30 be incorporated into wheel body 20 both sides, and two wheel covers 30 are limited to respectively in conjunction with on support arm 111, to complete a kind of structure of castor.

The structure of above-mentioned specific embodiment can obtain following benefit:

The utility model disposes respectively a wheel cover 30 by wheel body 20 both sides, and this wheel cover 30 is another coordinate assembled base 10 be provided with limiting section 33 in conjunction with support arm 111, when wheel body 20 coordinates while being mounted in conjunction with 111 of support arms, can wheel cover 30 be coated and be limited in conjunction with on support arm 111 with limiting section 33 simultaneously, provide again screw piece 12 and nut 13 packings to fix, make the involution section 31 of wheel cover 30 can be covered in wheel body 20 sides fully, can not only improve the lubricating condition of wheel body 20 bearing parts 22, and effectively prevent that foreign matter is involved in 10 of wheel body 20 and assembled bases, significantly promote castor service life, the practicality that lamps structure is used.

The above, be only a preferred embodiment of the present utility model, when not limiting the scope that the utility model is implemented with this; The equalization of generally doing according to the scope of the claims of the present utility model changes and modifies, and all should still belong in the scope that the claim of the utility model application contains.
