Abstract
The utility model discloses a kind of tow ball with anti-rotational groove, comprise spheroid, be positioned at round platform base below spheroid, be positioned at screw rod below round platform base, the outward flange of described round platform base is provided with the breach inwardly concaved.Utility model is provided with the breach inwardly concaved on the outward flange of round platform base, and be provided with latch in the relevant position of tow arm, when tow ball is fixed in tow arm, then latch is inserted this breach, thus play the effect avoiding tow ball to rotate, extend the service life of tow ball.Further, the both sides of the edge of described round platform base are the straight flange be parallel to each other, and both sides straight flange just forms the screens that spanner can be allowed stressed, fixes spheroid by spanner, and when avoiding fastening nut, tow ball follows nut rotation, easy for installation.
Description
Technical field
The utility model relates to a kind of vehicular spare parts, is specifically related to a kind of tow ball with anti-rotational groove.
Background technology
Tow ball is also towing hook after car puller hook, ball, is an accessory on tow arm, the spheroid that general tow ball comprises high strength and the screw rod be connected with trailer.Detouchable tow ball has rotation phenomenon in use, and when frequently rotating between tow ball and band iron, matching property between the two can be caused to decline, thread failure, bolt and nut assembling loosen, and produce potential safety hazard, service life shortens.For preventing the generation of rotation phenomenon, existing part manufacturer coordinates bolt and tow arm the restriction pad to be provided with to have concave-convex type, with limit tow ball and rotation, this technical scheme refers to the Chinese patent that the patent No. is 201420072656.X.But due to the often dismounting of tow ball needs, restriction pad is easily out of shape after a number of uses, and the effect making restriction rotate disappears, and can not play rotation-prevention effect well.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of tow ball with anti-rotational groove.
The utility model solves the technical scheme that its technical matters adopts:
With a tow ball for anti-rotational groove, comprise spheroid, be positioned at round platform base below spheroid, be positioned at screw rod below round platform base, the outward flange of described round platform base is provided with the breach inwardly concaved.
In the utility model, the both sides of the edge of described round platform base are the straight flange be parallel to each other.
In the utility model, stretching out of described round platform base edge, the length of extension is greater than the radius of spheroid, and breach is positioned at the most summit of extended spot.
In the utility model, the upper and lower surface of described extended spot is plane.
In the utility model, the top of described spheroid is horizontal surface.
The beneficial effects of the utility model are: the utility model is provided with the breach inwardly concaved on the outward flange of round platform base, and be provided with latch in the relevant position of tow arm, when tow ball is fixed in tow arm, again latch is inserted this breach, thus play the effect avoiding tow ball to rotate, extend the service life of tow ball.Further, the both sides of the edge of described round platform base are the straight flange be parallel to each other, and both sides straight flange just forms the screens that spanner can be allowed stressed, fixes spheroid by spanner, and when avoiding fastening nut, tow ball follows nut rotation, easy for installation.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is further illustrated:
Fig. 1 is the structural representation of the present embodiment;
Fig. 2 is the front view of Fig. 1;
Fig. 3 is the birds-eye view of Fig. 2;
Fig. 4 is A-A direction cutaway view of Fig. 2.
Detailed description of the invention
Referring to figs. 1 through Fig. 4, a kind of tow ball with anti-rotational groove that the present embodiment provides, comprise spheroid 1, be positioned at round platform base 2 below spheroid 1, be positioned at screw rod 3 below round platform base 2, described spheroid 1, round platform base 2 and screw rod 3 are made by high duty metal is one-body molded, the outward flange of described round platform base 2 is provided with the breach 4 inwardly concaved, described breach 4 can be circular hole or semicircle opening, optimum way is semicircle opening, and be free-running fit with the latch of tow arm, conveniently insert latch.
As preferred embodiment, the both sides of the edge of described round platform base 2 are the straight flange 5 be parallel to each other, and this straight flange 5 lays respectively at the both sides of breach 4.In the present embodiment, stretching out of described round platform base 2 edge, the length of extension is greater than the radius of spheroid 1, and breach 4 is positioned at the most summit of extended spot, breach 4 away from spheroid 1 to insert or to take out latch.The distance of the line of centers of the center-point distance screw rod 3 of described semicircle opening is 33mm, and the radius of spheroid 1 is 25mm, and distance is 1.3 ~ 1.5 with ratio the best of radius.The upper and lower surface of described extended spot is plane, and plane surface makes latch more easily take out.For convenience of coordinating tow ball case, the top of described spheroid 1 is horizontal surface.
The foregoing is only preferred embodiments of the present utility model, as long as the technical scheme realizing the utility model object with basic same approach all belongs within protection domain of the present utility model.
