Abstract

The utility model discloses an integrated tire screw, which comprises a screw rod, a middle cap sleeved at the rear end of the screw rod, a small cap in threaded connection with the front end of the screw rod, and an outer cap in threaded connection with the rear end of the middle cap, wherein the screw rod and the middle cap are connected by integral forming, one end of the outer cap far away from the screw rod is in a closed arrangement, and the middle cap is screwed into the screw hole of the outer cap and abuts against the closed end of the outer cap; this integral type tire screw production efficiency is high, and can reduce to rust and the impaired probability of screw thread.

Description

Integral type tire screw
Technical Field
The utility model relates to an integral type tire screw.
Background
As shown in fig. 1, the existing bolt assembly is composed of four parts, namely a screw 1, a middle cap 2, a small cap 3 and an outer cap 4, and four corresponding parts need to be produced, so that the working procedure is too long, more parts need to be produced, the matching assembly and disassembly are inconvenient, and the efficiency is low; meanwhile, the sand and dust and water enter the internal thread hole, so that the probability of rusting and thread damage is increased, and the service life of the hub nut assembly is shortened.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims at providing a production efficiency is high, and can reduce the integral type tire screw of rustting and the impaired probability of screw thread.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an integral type tire screw, including the screw rod, and the well cap of screw rod rear end is located to the cover, and threaded connection in the little cap of screw rod front end, and threaded connection in the outer cap of well cap rear end, the screw rod adopts integrated into one piece to be connected with well cap, the one end that the screw rod was kept away from to outer cap is closed setting, well cap screw in the screw hole of outer cap and lean on with the blind end counterbalance of outer cap.
Preferably, the closed end of the outer cap is arranged in an arc shape, and the closed end formed by the arc design is thicker and is not easy to damage.
Further, well cap is equipped with the chamfer towards one side in the outer cap, and the chamfer is used for the cooperation to be circular-arc outer cap and supports and lean on.
Furthermore, the length of the middle cap is larger than the length of the inner diameter of the outer cap, and the middle cap part is screwed into the outer cap.
Preferably, the length of the rod body of the screw is greater than that of the small cap, and the screw penetrates through the small cap.
The utility model has the advantages that:
the size of one end of the screw, which is originally matched with the middle cap to be used, is designed into the thread specification same as that of the middle cap, and the bolt assembly, which originally needs 4 parts, is reduced to only 3 parts, so that the production efficiency is improved, the production cost is reduced, and the loading and unloading efficiency is greatly improved; in addition, the outer cap is arranged to be a closed nut, so that the situation that sand dust and water enter the inner threaded hole can be effectively avoided, the probability of rusting and thread damage is reduced, and the service life of the hub nut assembly is prolonged.
Drawings
FIG. 1 is a schematic structural view of a conventional bolt assembly;
fig. 2 is a schematic structural diagram of the integrated tire screw of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
Example (b):
referring to fig. 2, the integrated tire screw comprises a screw rod 1, a middle cap 2 sleeved at the rear end of the screw rod 1, a small cap 3 in threaded connection with the front end of the screw rod 1, and an outer cap 4 in threaded connection with the rear end of the middle cap 2, wherein the screw rod 1 and the middle cap 2 are integrally connected, one end of the outer cap 4, which is far away from the screw rod 1, is in a closed arrangement, and the middle cap 2 is screwed into a screw hole of the outer cap 4 and abuts against the closed end of the outer cap 4.
The blind end of outer cap 4 is circular-arc setting, and the blind end that the circular arc formula design formed is thicker, and is not fragile, well cap 2 is equipped with the chamfer towards one side in outer cap 4, and the chamfer is used for the cooperation to be circular-arc outer cap 4 and supports and lean on, the length of well cap 2 is greater than the internal diameter length of outer cap 4, in the outer cap 4 of 2 partial screw ins of well cap, the pole body length of screw rod 1 is greater than the length of little cap 3, and screw rod 1 runs through little cap 3.
The utility model has the advantages that:
improved on the basis of original steel sheet round pin structure, oil outlet department has set up an oil outlet recess, avoided making the jam that causes between oil outlet and the bush under the effect of gravity and lead to the condition that the butter can not get into, the pole portion on the both sides of oil outlet place recess sets up the external screw thread in addition, the bush that the cooperation was used also sets up the internal thread of same specification, with the rotation effect of interlock each other between the screw thread, replace the mutual friction rotation effect between steel sheet round pin and bush, wear and tear has been reduced, can be more effectual the life of extension steel sheet round pin.
The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
