Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution: the fastening nut combined sleeve for the electric vehicle direction column comprises an inner sleeve 1 and an outer sleeve 2, a connecting sleeve 3 is clamped at the top end inside the inner sleeve 1, the inner sleeve 1 is clamped inside the outer sleeve 2, the inner sleeve 1 and the outer sleeve 2 form an adjustable fixed connection structure through a limiting point 4 and a steel ball 5, the steel ball 5 is clamped inside the limiting point 4, a plurality of groups of limiting holes 8 which are equidistant and correspond to the limiting point 4 are arranged at the top of the outer sleeve 2, the limiting point 4 and the limiting holes 8 are distributed in a circumferential manner, the diameter of each limiting hole 8 is larger than the outer diameter of the limiting point 4, a set screw 6 is in threaded connection with one end inside the limiting hole 8, a compression spring 7 is sleeved outside the set screw 6, one end of the compression spring 7 is connected with the steel ball 5, a small nut hole 10 is arranged at the bottom end inside the inner sleeve 1, and a large nut hole 9 is arranged inside the outer sleeve 2, the large nut hole 9 and the small nut hole 10 are both in a regular octagonal structure.

When the small nut needs to be screwed down, the outer sleeve 2 only needs to be stirred upwards, and the outer sleeve 2 can be clamped at the position of the limiting point 4 on the outer side of the inner sleeve 1 under the action of the steel balls 5 and the compression spring 7, so that the outer sleeve 2 can be prevented from falling downwards during fastening.

When the large nut needs to be screwed down, the outer sleeve 2 is pulled downwards, and the outer sleeve 2 is clamped on the lower limit point 4 of the inner sleeve 1.

This structure is whole to link to each other with the rifle head of wind-powered cannon, and wear the lockpin, need not to make a round trip to get ring inner skleeve 1 and outer sleeve 2, thereby labour saving and time saving more, operator's intensity of labour has been reduced, further improvement the installation effectiveness, at last with the wind-powered cannon again, the combination sleeve hangs in the assembly line top with three kilograms of pneumatic block hoist, only need during the assembly to pull down the sleeve and can use, the fastening finishes the back, loosen the hand can, the wind-powered cannon contracts to the settlement position under the effect of the pull force that the whole pneumatic block of combination sleeve hung.
