As improvement, a described N groove surrounds the annular ring of one 360 degree, can realize omnibearing location.

Improve, the spacer portion between the described N groove is equidistant setting respectively again, makes structural stability, stressed even.

Improve, described positioning device is 2～5 again, and positioning performance is more stable.

Improve, described rolling element can be ball or needle roller again.

Improve again, described positioning device includes ball and spring, and described spring flexible place the cavity of inner ring, described ball can rollably be placed in the end of spring, the afterbody of described spring and the bottom support of cavity make the positioning device operational effect better together.

Improve again, described positioning device also comprises mounting box and chock plug, described mounting box places the cavity of inner ring, described spring places mounting box, described ball stretches out from an end of mounting box, the afterbody of described spring is connected with chock plug, and described chock plug is fixed in the bottom of mounting box, to guarantee the normal operation of positioning device.

Compared with prior art, the utility model employing compartment of terrain on the inwall of outer ring is arranged with N groove, a described N groove is positioned on the same circumferential surface, spacer portion in described groove between every adjacent two grooves is arc surface, on the periphery wall of described inner ring, be provided with at least the positioning device of a spherical shape slip plug, described spherical shape slip plug can be inserted in the groove of arrangement when inner ring and outer ring relatively rotate forward or backward successively, and described N is natural number.The advantage of this design is: not only simple in structure, fabricating cost is low, and can effectively realize relative positioning between the outer ring of bearing and the inner ring, in the time of door or window can being turned to desired location, after decontroling hand, door or window namely are positioned this place, use very conveniently, this technology has particularly played revolutionary improvement to the location of swing door.

Embodiment

Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1 to 7, the place kick bearing of present embodiment, include outer ring 2, inner ring 1 and rolling element 3, described rolling element 3 can rollably place between outer ring 2 and the inner ring 1,: the compartment of terrain is arranged with N groove 4 on the inwall of described outer ring 2, a described N groove 4 is positioned on the same circumferential surface, spacer portion in described groove 4 between every adjacent two grooves 4 is arc surface, on the periphery wall of described inner ring 1, be provided with at least the positioning device 5 of a spherical shape slip plug, described spherical shape slip plug can be inserted in the groove 4 of arrangement when relatively rotating in inner ring 1 and outer ring 2 forward or backward successively, described N is natural number, described rolling element 3 can be ball, also can be needle roller, specifically can decide by designing requirement.

A described N groove 4 surrounds the annular ring of one 360 degree, and its interval section is preferably respectively equidistant setting.Described positioning device 5 is 2～5, and is perhaps more, specifically decides according to design.The preferred structure of described positioning device 5 is: include ball 51 and
