Abstract

The utility model relates to steering wheel assistant rotary grip which is used on the transporting vehicles such as an automobile, a tractor, and a gripper fork and the like, comprising a holding part which is held and fixed on a steering wheel, a threaded stud pole which is fixed on the holding part with an axial pin, a handle ball which is installed on the threaded stud pole and moves around the threaded stud pole relatively, a bearing which is installed between the handle ball and the threaded stud pole, and a clamp fixed mechanism which is installed between the threaded stud pole and the holding part. The clamp fixed mechanism can force the threaded stud pole vertically stand or bend toward the radial direction of the steering wheel, and the threaded pole does not project upwards to surpass the plane of the steering wheel. The utility model has the advantages of simple structure, and flexible and convenient employment and operation, and can be installed on steering wheels of vehicles of various types and be used.

Description

The convenient steering tiller of bearing circle

The utility model relates to the bearing circle assisted control spare that uses on the transportation meanss such as a kind of automobile, trac., forklift, particularly can make the quick handle that rotates of annular arrangement bearing circle horizontal direction.

Employed annular arrangement bearing circle on the transportation meanss such as automobile of the prior art, trac. all is to change travel direction for chaufeur, and its structure is that the annular arrangement bearing circle links to each other with direction mechanism.Its weak point is the bearing circle inconvenience that operates, and operation is driven dumbly during particularly big turning, needs with the hands that the mode of repeated overlapping alternately spurs, and just can finish driving.In order to address the above problem, on April 2nd, 1997 Chinese Patent Office to disclose publication number be that CN1146413A, name are called the technology of " a kind of auxiliary device of direction of operating dish ".It is fixed on a folder that has handle on the bearing circle, in use, handle is stood on the bearing circle, gets final product with singlehanded direct control direction.And when not using, remain on bending state.Therefore, it has solved the problem of twirl bearing circle preferably, has also solved the outstanding obstacle that can become the motion that hinders arm or hand of upright handle simultaneously.But owing to the turning handle of operation is enclosed within on the upright bar, so come off easily; Be not come off, long-term use, wearing and tearing are easy to generate bigger gap between handle and the bar, and handle supports unstable, causes operation control inaccurate.

The purpose of the utility model is to provide a kind of operation more flexible, handle difficult drop-off or the wheel steering handle that hangs.Its technical scheme is such: it comprises a folder that is clamped on the bearing circle, one is fixed on double-screw bolt bar on the folder with pivot pin, and one be installed on the double-screw bolt bar to make handle ball in relative rotation around the double-screw bolt bar, is contained in the bearing between handle ball and the bolt shank.

For easy to assembly, handle ball of the present utility model is divided into pallet and loam cake two parts down, makes up with screw; Following pallet is enclosed within on the bolt shank, and a gap is seldom arranged; Bearing is mounted in down in the upper port of pallet, and bearing hole is fixed in the bolt shank upper end.Like this, handle ball can be rotated neatly on bolt shank and do not come off, and reaches the purpose of the utility model.

Preferably, the utility model also is equipped with fastening mechanism between bolt shank and folder, this fastening mechanism establishes a hole clipping on folder, this hole clipping communicates with bolt shank, spring, bayonet lock are housed on it, bayonet lock is provided with a projection near spring terminal, has the groove that matches with projection on the bolt shank bottom; When bolt shank was upright, projection withstood on the groove, and bolt shank uprightly can not be rotated; When pressing bayonet lock, projection leaves the groove of bolt shank, and bolt shank can directly bend inwards to bearing circle and can not project upwards plane above bearing circle.

Obviously, the utlity model has simple in structurely, use flexible operation, convenience, can be installed on the bearing circle of all kinds car and use.

Below in conjunction with embodiment shown in the drawings, the utility model is described in further detail.

Fig. 1 is a structure cutaway view of the present utility model.

Fig. 2 is the B-B cutaway view of Fig. 1.

Fig. 3 is the A-A cutaway view of Fig. 1.

Fig. 4 is the scheme drawing after the utility model bending.

Referring to Fig. 1, Fig. 2, Fig. 3, the convenient steering tiller of bearing circle is by the folder 2 that is clamped on the bearing circle, is fixed on bolt shank 6 on the folder 2 with pivot pin 4, be enclosed within the handle ball 1 on the bolt shank 6 and be contained in handle ball 1 and bolt shank 6 between bearing 7 form.

Folder 2 is made of the upper clip 2a that has pedestal and lower clip 2b and the hinge axle 2c that is connected them; Upper clip 2a and lower clip 2b are fulcrum opening and closing up and down with hinge axle 2c, and fix with bolt 5 and clamping, have location thorn 2d in upper and lower clamp 2a, the 2b.

Handle ball 1 is made mushroom, is made of following pallet 1b and loam cake 1a, and assembles with screw 9.Following pallet 1b is horn-like, and bearing 7 is mounted in down on the port of pallet 1, and bolt shank 6 lower diameter are slightly less than down pallet 1b bottom internal diameter, and upper diameter matches with bearing 7 apertures, and is fixed on the bearing 7 interior rings with nut 8.

The lower end of bolt shank 6 is in the flat-shaped pedestal that is contained in upper clip 2a with pivot pin 4, and can do 90 ° rotation around pivot pin 4; Can lock when making the bolt shank erectility, fastening mechanism is housed in pedestal, fastening mechanism comprises spring 10, the bayonet lock 11 that is contained in the fastening hole 12, bayonet lock 11 1 ends are stretched outside pedestal, the other end withstands on the spring 10, fastening hole 12 communicates with bolt shank 6, and bayonet lock 11 correspondingly has groove with matching establishing a projection 11a near the relative bolt shank of spring 10 1 ends 6 positions on bolt shank 6.When bolt shank 6 was upright, projection 11a withstood on the groove just, makes bolt shank 6 can not bend rotation, thereby locks its stand up position; When without handle ball 1, press bayonet lock 11, make projection 11a leave bolt shank 6 grooves, bolt shank 6 can be to the inner bending of bearing circle plane, referring to Fig. 4, thereby has avoided the disadvantage on handle ball 1 projected direction dish plane.

Handle ball 1 of the present utility model also can be other geometric configuratioies such as sphere, ellipse.
