Abstract
The utility model provides a U -bolt locking sphere locknut, this nut comprises nut body and spherical pad circle two parts, the nut body below is arranged in to the spherical pad circle, so that its better contacting with the nut fitting surface, with the axial force of guaranteeing U -bolt, simultaneously be toper diameter -adjustable structure at the binding off position along the axial at the internal thread of nut body part, four screw thread reducing part circumference equipartitions' U' type notch, because the clamp bolt head is inclined to the toper shape of reducing part hole, the frictional force between nut and the bolt head has been increased, thereby good locking effect has been realized. Traditional structure is compared to this improvement nut, has that to twist moment little, characteristics that the moment of back -outing is big to frequently not hard up problem of U -bolt has been solved well.
Description
Technical field
The utility model relates to heavy-duty car fastener areas, is specifically related to a kind of retainer nut.
Background technology
At present, shaken for a long time due to suspension part U-bolts connection portion or the impact of bad working environments, cause the problems such as the bolt of junction easily occurs loosening, fracture, this position major part vehicle adopts traditional all-metal set nut, be screwed into when this nut has assembling moment little, surface-treated layer and the outside screw thereof of mating parts are had the shortcomings such as certain damage.
Practical novel content
For this reason, the utility model installs structure in conjunction with the U-bolts of suspension system, it is provided that a kind of U-bolts locking sphere retainer nut, it can solve primary structure bolt Joint failure problem better.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of U-bolts locking sphere retainer nut, it is characterized in that, it is assembled into one by nut main body and spherical washer two portions, it is characterized in that spherical washer is placed in below nut main body, the internal thread of nut main body part is at the tapered reducing in closing in position, and is evenly distributed in multiple notch along closing in part.
Preferably, the notch quantity of retainer nut main body reduced diameter portion is four.
Preferably, the shape of the notch of retainer nut main body reduced diameter portion is " U " type.
Preferably, this nut main body comprises main part 2, reduced diameter portion 3, the middle portion of nut main body is tubular main part 2, the outer surface structure of main part 2 is the nut shape of polygonal head, the inner chamber of main part 2 is threaded circular hole, and reduced diameter portion 3 outwards extends from the open end of main part 2; The internal thread hole of reduced diameter portion is apered to taper along the axial direction due away from main part 2, and the circumferentially uniform of reduced diameter portion 3 has at least four notches 4.
Preferably, notch 4 is not more than the axial length of conical section along the degree of depth of the axis of reduced diameter portion 3.
Preferably, notch 4 is " U " type.
Preferably, the axial length of the conical section of reduced diameter portion 3 is no more than 1/3rd of main part 2 length.
Preferably, main part 2 is hex-head nut.
Preferably, the difference of the external diameter of nut reduced diameter portion and the external diameter of nut main body part is more than or equal to 3mm.
Preferably, spherical washer and nut main body are buckle-type radial compaction assembly structure, and the sphere of spherical washer coordinates with assembly as assembling face.
Retainer nut of the present utility model has that to be screwed into moment little, the feature that moment of back-outing is big. The assembling face of retainer nut is spherical shape, so that it better contacts with nut mating surface, to ensure the axial force of U-bolts.
The beneficial effects of the utility model are: solve conventional suspension systems U-bolts by the problems affect such as comfortable property, overload, cause U-bolts preliminary tension decay, occur that bolt frequently loosens, ruptures, decrease fault, it is to increase the reliability of vehicle.
Accompanying drawing explanation
Fig. 1 is the cutting diagram of the front view of an embodiment of U-bolts of the present utility model locking sphere retainer nut;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the stereographic map of an embodiment of U-bolts of the present utility model locking sphere retainer nut;
In figure: 1 spherical washer, 2 main parts, 3 reduced diameter portions, 4 notches.
Embodiment
Now by reference to the accompanying drawings 1,2,3 and specific embodiment the utility model is further described.
The middle portion of this retainer nut is can in the main part 2 of column. The shape of this main part 2 can be arranged to be similar to traditional metal nuts. For the ease of the handling of this retainer nut, the outer surface structure of main part 2 can be arranged to the structure being suitable for carrying out screwing with hand or instrument, main part 2 is hex-head nut, and the inner surface structure of main part 2 can be the thread circle hole being suitable for being screwed on the bolt head mated mutually with nut. Reduced diameter portion 3 extends from the end of the main part 2 of retainer nut. Main part can also be five jiaos of first-class nut structures.
Such as the cutting diagram in Fig. 1, the threaded hole of reduced diameter portion 3 is apered to taper along the direction away from main part 2, and reduced diameter portion 3 place circumferentially can be evenly equipped with at least four notches 4. In preferred enforcement mode, notch 4 should be not more than the height of taper along the degree of depth of the axis of reduced diameter portion 3. In order to realize different degree of tightness effects, it is also possible to notch 4 to be suitably arranged to " U " type. The height (namely conical section is along the axially extended length of nut) of the conical section of reduced diameter portion 3 can be no more than main part 2 length 1/3rd to improve anti-loosening property, avoid reducing anti-loosing effect due to the distortion of this conical section.
As can be seen from Figure 1, the maximum diameter place of reduced diameter portion 3 is not more than the inscribed circle diameter of the outside surface of main part 2, hinders screw thread for preventing from drawing, and this value is not more than 3mm.
Spherical washer part 1 improves retainer nut and the contact surface of parts to be connected, it is possible to prevent from loosening to a certain extent. By reference to the accompanying drawings and above-mentioned explanation can understand, when screwing locking spiral shell of the present utility model relative to bolt head, make conical section be easy to elasticity open due to the existence of notch 4 that is arranged on reduced diameter portion 3, it is possible to be convenient to nut being screwed into and back-outing relative to bolt head; When being screwed to bolt head by retainer nut of the present utility model, owing to the conical by its shape in hole tends to push bolt head in reduced diameter portion 3, add the frictional force between nut and bolt head, thus achieve good locking effect.
Finally should be noted that: above embodiment is only not intended to limit in order to the technical scheme of this case to be described; Although this case being described in detail with reference to better embodiment, those of ordinary skill in the field are it is understood that still can modify to the embodiment of this case or part technology feature carries out equivalent replacement; And do not depart from the spirit of this case technical scheme, in the middle of its technical scheme scope that all should be encompassed in this case request protection.
