SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, antidetonation, locking effectual U-shaped bolt structure for automobile assembling to the not enough of existence among the above-mentioned background art.
In order to achieve the above object, the utility model relates to a U-shaped bolt structure for automobile assembling has adopted following technical scheme:
the utility model provides a U-shaped bolt structure for automobile assembling, includes the U-shaped pole, the both ends of U-shaped pole all are provided with the screw thread section, the both ends of U-shaped pole still are provided with the elastic component, the elastic component with screw thread section dislocation.
The utility model relates to a further improvement part of U-shaped bolt structure for automobile assembling lies in, the elastic component upper end is connected with the locating piece, locating piece sliding connection in the U-shaped pole.
The utility model relates to a U-shaped bolt structure's for automobile assembling further improves part lies in, the locating piece is the annular, horizontal screw has been seted up to the locating piece, be provided with a plurality of second screws that vertical evenly laid on the U-shaped pole, the screw is the same with second screw size, screw and second screw department spiro union have the bolt.
The utility model relates to a further improvement part of U-shaped bolt structure for automobile assembling lies in, the elastic component is the spring or the inside telescopic link that is equipped with the spring.
The utility model relates to a further improvement part of U-shaped bolt structure for automobile assembling lies in, screw thread section spiro union has the nut, be provided with annular limit baffle on the nut, the limit baffle inner circle is fixed with the cushion, the cushion surrounds and supports the screw thread section.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses U-shaped bolt structure is provided with the elastic component at screw section department for when U-shaped bolt and nut cooperation used, the elastic component can support the leaf spring of car, and then realizes the shock attenuation to the U-shaped bolt of spiro union and nut junction, is provided with the cushion on the nut simultaneously and has also further guaranteed the locking of nut and U-shaped bolt.
Drawings
Fig. 1 is a schematic structural view of the present invention;
in the figure: 1U-shaped pole, 2 screw thread sections, 3 elastic components, 4 locating pieces, 5 second screw holes, 6 bolts, 7 nuts, 8 limit baffles and 9 elastic cushions.
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.
As shown in fig. 1, the U-shaped bolt structure for automobile assembly comprises a U-shaped rod 1, wherein both ends of the U-shaped rod are provided with thread sections 2, and the thread sections can be formed by turning and milling or welding. Elastic pieces 3 are further arranged at two ends of the U-shaped rod, and the elastic pieces are staggered with the thread sections. Specifically, the upper end of the elastic part is connected with a positioning block 4, and the positioning block is connected to the U-shaped rod in a sliding mode. The positioning block is annular, the positioning block is provided with a transverse screw hole, the U-shaped rod is provided with a plurality of vertical second screw holes 5 which are uniformly distributed, the size of each screw hole is the same as that of each second screw hole, and the screw holes and the second screw holes are in threaded connection with bolts. The adjusting through the positioning block enables the elastic piece to adapt to different steel plate springs, and the proper contact with the steel plate springs is guaranteed, so that the damping effect is guaranteed. Specifically, the elastic part is a spring or a telescopic rod with a spring arranged inside. Furthermore, the threaded section is in threaded connection with a nut 7, an annular limiting baffle 8 is arranged on the nut, an elastic cushion 9 is fixed on the inner ring of the limiting baffle, and the elastic cushion can surround and abut against the threaded section. The locking between the U-shaped bolt and the nut is ensured.
The utility model discloses a theory of operation does: with U-shaped bolted connection axle and leaf spring, adjust the position of locating plate for elastic component contact leaf spring's degree is appropriate, reuse nut locking U-shaped bolt, because the extrusion of cushion realizes the locking of nut and bolt section, and in the whole, when setting up of elastic component made automobile vibration, the buffer can be received with the junction of bolt to the nut, realizes the shock attenuation.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
