Said base is made up of base upper cover and base bottom; Said circular hole is opened on the base upper cover; Said ball rolling bearing mechanism more than three or three is installed between base upper cover and the base bottom through screw, and the ball in the ball rolling bearing mechanism is positioned on the inwall of said circular hole.
Said ball rolling bearing mechanism includes: bearing block, sleeve, spring and ball; Spring and steel ball are installed in the sleeve; Sleeve is installed in the bearing block; Spring one end is pressed on the bearing block, is pressed on the ball after the spring other end compression and makes the part of ball stretch the inner wall position that arrives said circular hole behind the through hole on protrusion sleeve ends through hole, the bearing block successively.
The sidewall of said round turntable has the V-shaped groove that rolls and cooperate with said ball, and said bearing block supports round turntable through ledge structure.
Said lamp body and round turntable are fixed together through several screws.
Said round turntable center is provided with the power connection seat with conducting circular cylinder connected in star, and the cylindrical power connection end that connects power line is inserted in the conducting circular cylinder connected in star of power connection seat from base bottom intermediate vertical.
Also be provided with in the said base bottom central slot and be used for the annular stator of setting circle cylindricality power connection end.
Said ball rolling bearing mechanism more than three or three evenly is located on the inwall of said circular hole.
After adopting said structure, the rolling between this novel V-shaped groove that passes through on ball and the round turntable cooperates, and just can easily realize rotating freely of 360 degree, and utilizes bearing block to pass through ledge structure and support round turntable.And the electric mode that connects of the vertical grafting of the power connection seat of conducting circular cylinder connected in star and cylindrical power connection end makes and also can realize in the rotation process being abutted against electricity and can not cause the coiling phenomenon.

The specific embodiment
Shown in Fig. 1-6; A kind of 360 degree tumblers of desk lamp; Include: the round turntable 20 and the base 30 that are fixedly connected with lamp body 10; On base 30, have the circular hole 30a that supplies round turntable 20 to embed, in the ball rolling bearing mechanism 40 that is distributed with on the inwall of said circular hole 31 more than three or three, said ball rolling bearing mechanism 40 and round turntable 20 cooperatively interact to support round turntable 20 and to supply round turntable 20 to rotate.
Said base 30 is made up of base upper cover 31 and base bottom 32; Said circular hole 30a is opened on the base upper cover 31; Said ball rolling bearing mechanism 40 more than three or three is installed between base upper cover 31 and the base bottom 32 through screw 40a, and the ball 41 in the ball rolling bearing mechanism 40 is positioned on the inwall of said circular hole 30a.
Said ball rolling bearing mechanism 40 includes: bearing block 42, sleeve 43, spring 44 and ball 41; Spring 44 is installed in the sleeve 43 with steel ball 41; Sleeve 43 is installed in the bearing block 42; Spring 44 1 ends are pressed on the bearing block 42, are pressed on the ball 41 after spring 44 other ends compressions and make the part of ball 41 stretch the inner wall position that arrives said circular hole 30a behind the through hole on protrusion sleeve 43 end through holes, the bearing block 42 successively.
The sidewall of said round turntable 20 has the V-shaped groove 20a that rolls and cooperate with said ball 41, and said bearing block 40 supports round turntable 20 through ledge structure 45.
Said lamp body 10 is fixed together through several screws 10a with round turntable 20.
Said round turntable 30 centers are fixed with the power connection seat 50 with conducting circular cylinder connected in star through screw, and the cylindrical power connection end 61 that connects power line 60 is inserted in the conducting circular cylinder connected in star of power connection seat 50 from base bottom 32 intermediate vertical.
Also be provided with in the said base bottom 32 central slot 32a and be used for the annular stator 70 of setting circle cylindricality power connection end 61.
Said ball rolling bearing mechanism 40 more than three or three evenly is located on the inwall of said circular hole 30a.
During use; Ball 41 in the ball rolling bearing mechanism 40 can adopt steel ball to make; The external part of ball 41 is squeezed in the V-shaped groove 20a on the sidewall of round turntable 30 under spring 44 effect; When lamp body 10 was rotated on the plane, the rolling of the round turntable 20 that is fixed together with lamp body 10 through V-shaped groove 20a and ball 41 was engaged in the circular hole 30a at round turntable 20 centers and rotates;
Because to connect electrical mechanisms is vertical sleeve structure Design, therefore, relatively rotating in the process of round turntable 20 and base 30, cylindrical power connection end 61 power connection seat 50 in the commentaries on classics of conducting circular cylinder connected in star inward turning and remain and connect electricity condition.
Like this, the rolling between this novel V-shaped groove 20a that passes through on ball 41 and the round turntable 20 cooperates, and just can easily realize rotating freely of 360 degree, and utilizes bearing block 40 to support round turntable 20 through ledge structure 45.And the electric mode that connects of the vertical grafting of conducting circular cylinder connected in star in the power connection seat 50 and cylindrical power connection end 61 makes and also can realize in the rotation process being abutted against electricity and can not cause the coiling phenomenon.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
