Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
To shown in Figure 5, at first, there is a rotating shaft 10 as Fig. 2.In order to adjust rotating shaft 10, the input end of rotating shaft is designed to square, and the output terminal design has keyway.In order to lock this axle, designed gear 9, gear passes through key 8 transmitting torques with axle.Smooth and easy for rotating shaft 10 is rotated, on the axle bearing 6 has been installed.For locking gear 9, designed locking jaw 13, design has a plurality of internal tooths supporting with gear 9 on the locking jaw, utilizes the lever principle of locking jaw simultaneously, and himself can provide very large coupling mechanism force.Locking jaw is realized disengagement and engagement with gear 9 around straight pin 12 rotations.Design spiral tension spring 11 on the locking jaw 13 simultaneously, realized resetting certainly of locking jaw.Because locking jaw is swung, and is spacing for it is carried out, prevent from simultaneously to mesh and unclamp, designed position limit pin 5.For position limit pin is resetted, be provided with helical compression spring 4 simultaneously.For ease of twitching position limit pin 5, in the end design of pin screw thread is arranged, there is knurled nut 2 coupled.For gear 9 is carried out axially locating, design has axle sleeve 7.A string component in the last rotating shaft 10 are installed in the locking shell of being made up of tightening cover 3 and locking bed 14, and tightening cover and locking bed are fastening by bolt 1.Assembly relation is as follows: locking bed 14 is fixing, and bearing 6 is packed in the counterbore of locking bed 14.Whole string axle system is formed in the rotating shaft 10, key 8, gear 9, axle sleeve 7, bearing 6 of packing into successively.Then straight pin 12 is inserted in the pin-and-hole of locking bed 14, again locking jaw 13 is placed on the straight pin 12.Then helical compression spring 4 is placed on the position limit pin 5, the two is inserted in the circular hole of tightening cover 3 together, simultaneously the threaded end of position limit pin is exposed tightening cover 3 and screw with knurled nut 5.At last tightening cover 3 and locking bed 14 are lumped together, tighten with bolt 1.
The concrete use operated: during locking state: locking jaw 13 meshes by internal tooth on the pawl and gear 9, limited pin 5 restrictions of its swing simultaneously around straight pin 12, and this moment, locking jaw was in steady state, and gear 9 also can't rotate, and reaches the purpose of locking rotating shaft 10.When rotating shaft 10 is rotated if desired, by knurled nut 2 position limit pin 5 is extracted certain displacement, locking jaw 13 is pulled disengaging gear engagement states open mode, discharge knurled nut 2, position limit pin 5 automatically resets under the effect of helical compression spring 4, and its head inserts in the hole of locking bed 14.Locking jaw 13 is owing to spacing maintenance of position limit pin 5, throw off with gear 9 at this moment, and rotating shaft 10 is free to rotate.Because position limit pin 5 is mixed in the existence of spiral tension spring 11 again, locking jaw 13 can not produce any swing when open mode.And in case when not needing rotating shaft 10 to rotate, extract position limit pin 5 once more, then locking jaw 13 automatically resets under the effect of spiral tension spring 11, and with gear 9 tight engagement, rotating shaft 10 is locked.
It should be noted that at last: above embodiment is the described technological scheme of unrestricted the utility model in order to explanation the utility model only; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed among the claim scope of the present utility model.
