Abstract
The utility model discloses a flat elliptical bolt, which comprises a flat elliptical ball, forward screw threads and a threaded rod. The flat elliptical bolt is characterized in that the forward screw threads are left on the threaded rod of the flat elliptical ball. When in use, the flat elliptical ball of the flat elliptical bolt is clamped by a spheroidal wrench, the forward screw threads on the threaded rod are sleeved in a screw cap in the prior art, and the forward screw threads are fastened or released. The flat elliptical bolt has the advantages of simple design, low cost and strong practicability, and transition implementation can be reached through the selling control of ball-shaped wrenches thereby guaranteeing the safety of railways.
Description
Affiliated technical field
The utility model relates to a kind of flat oval spherical bolt, relates in particular to the antitheft flat oval spherical bolt of a kind of railroad rail, belongs to technical field of fastening.
Background technique
At present, the railroad rail anti-theft bolt of known technology, study more active, fettered by thought of people, the Wrench of only considering prior art is matched in the railroad rail anti-theft bolt, before the utility model is not made, the use of the antitheft flat oval spherical bolt of no railway rail, the patent searching document does not have disclosing of technological scheme.
Summary of the invention
There is not the deficiency of the antitheft flat oval spherical bolt of railway rail in order to overcome prior art; the purpose of this utility model is in order to provide a kind of railroad rail antitheft flat oval spherical bolt; this ellipse spherical bolt uses the spheroidal spanner to tighten or loosen; because of the spheroidal spanner involves great expense; thereby also can retrain robber's pilferage behavior, thereby protect the safety of railway.
In order to reach the purpose of this utility model, the technological scheme that its technical problem that solves the utility model adopts is: by flat oval ball, forward screw thread, screw rod are formed, it is characterized in that leaving forward screw thread on the screw rod on the flat oval ball, with spheroidal spanner clamping flat oval ball of the present utility model forward screw thread on the screw rod and prior art nut are inserted in during use, make forward screw threads for fastening or unclamp to get final product.
The beneficial effects of the utility model are: simplicity of design, and with low cost, can reach transition by the sales control of spherical spanner and implement to guarantee railway security that practicability is bigger.
