Schematic diagram when Fig. 2 is arrangement of clutch locking described in the utility model idle running.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is described in further detail:

A kind of arrangement of clutch of lock comprises that clutch inner ring 1, clutch outer ring 2, clutch are sold inside the country 3, clutch export trade 4 and clutch pivoted arm 5.

Clutch outer ring 2 is sleeved on the clutch inner ring 1, and disconnected from each otherly leaves certain space; Radially be provided with a hole 6 on the clutch inner ring 1; Radially also be provided with a shoulder hole 7 that runs through clutch outer ring 2 corresponding to the position in hole 6 on the clutch outer ring 2, big outer little in the shoulder hole 7; Clutch export trade 4 is contained in the shoulder hole 7, and it is "T"-shaped and interior big outer little that clutch export trade 4 is, and the diameter of its each several part matches with the aperture of shoulder hole 7 each several parts, guarantees that clutch export trade 4 can not skid off from shoulder hole 7 fully; Clutch sold inside the country 3 is contained in the hole 6, and sold inside the country 3 one ends of clutch withstand clutch export trade 4, between the inwall of the other end and clutch inner ring 1 spring 8 are housed; Clutch sold inside the country 3 is equipped with lead angle with the end face that is connected of clutch export trade 4;

Clutch pivoted arm 5 one ends are fixed, and the other end connects driving mechanism, and the stage casing of clutch pivoted arm 5 is corresponding to the position in hole 7 and withstand clutch export trade 4, and the shape in the stage casing of clutch pivoted arm 5 matches with the shape of the outer wall of clutch outer ring 2.The driving mechanism of clutch pivoted arm 5 comprises spring 9, worm gear 10, worm screw 11 and motor 12; Worm screw 11 is contained on the axle of motor 12; Worm gear 10 and worm screw 11 engagements; The movable end of described clutch pivoted arm 5 is provided with a hole 13, and spring 9 is fixed on the worm gear 10, in its external part patchhole 13.

As shown in Figure 1, motor 12 is just changeing, and drives worm gear 10 clockwise directions by worm screw 11 and rotates, and the spring 9 on the worm gear 10 is stirred clutch pivoted arm 5 and counterclockwise rotated, clutch pivoted arm 5 unclamps clutch export trade 4, and clutch export trade 4 and clutch sold inside the country 3 outwards moved under the effect of spring 8.At this moment, clutch sold inside the country 3 is inserted in hole 6 and the hole 7 simultaneously, thereby clutch sold inside the country 3 connects clutch inner ring 1 and both interlocks are realized in clutch outer ring 2, has just realized " closing " state of arrangement of clutch.

As shown in Figure 2, motor 12 counter-rotatings, driving worm gear 10 by worm screw 11 counterclockwise rotates, spring 9 on the worm gear 10 is stirred clutch pivoted arm 5 clockwise directions and is rotated, clutch pivoted arm 5 inwardly holds out against clutch export trade 4, inwardly the top is from the hole 7 with clutch sold inside the country 3 in clutch export trade 4, and clutch export trade 4 only is inserted in the hole 7, and clutch sold inside the country 3 also only is inserted in the hole 6.At this moment, the luxuriant inner ring 1 that closes separates with clutch outer ring 2, and rotate clutch outer ring 2, can not drive clutch inner ring 1 and rotate, just realized arrangement of clutch " from " state.Here, the space between clutch inner ring 1 and the clutch outer ring 2, and clutch sold inside the country 3 is connected end face with clutch export trade 4 lead angle has guaranteed that all clutch inner ring 1 separates reliably with clutch outer ring 2.
