Abstract
An anti-theft bolt comprises a screw (1), a nut (2), an auxiliary screw (3) and a spanner (6). The anti-theft bolt is characterized in that a semi-circular head (5) is arranged at one end of the screw (1) of the anti-theft bolt, a left-hand screw blind hole (C) is formed in the other end, and the nut (2) is arranged at the left-hand screw blind hole (C). According to the anti-theft bolt, the bolt is novel in structure and convenient to operate. Stealing of valves and equipment can be prevented, the normal production of oil fields is guaranteed, the oil field economic benefit and the oil field management level are improved, leakage of oil, gas and water energy is prevented, the environment is protected, and the post worker labor intensity is reduced.
Description
Technical field
the utility model relates to parts bolton anti-theft technique, specifically a kind of anti-theft bolt.
Background technique
the equipment such as field, current oil field oil, well, valve group are various, generally with bolts, conventional bolt is non-anti-theft, and valve, the stolen phenomenon of equipment often occur, and to field produces, bring serious harm, not only affecting oil field normally produces, and cause serious economic loss to oil field, and affect the raising of field management level, even cause oil, gas, Water Energy to leak, befouling environment, has increased post workman's labor intensity.
Summary of the invention
the purpose of this utility model is exactly in view of the foregoing defects the prior art has, designs a kind of anti-theft bolt.
the utility model is realized by following technical proposals:
the utility model comprises: screw rod, nut, auxiliary screw rod, spanner.Screw rod one end of its anti-theft bolt is provided with cup head, and the other end is provided with left-hand thread tapped blind hole, and on have nut.
nut in above-mentioned anti-theft bolt is hollow truncated cone-shaped, and the conical surface is provided with two symmetrical posts holes.
on screw rod in above-mentioned anti-theft bolt, the screw thread of left-hand thread tapped blind hole is trapezoidal thread.
auxiliary screw flight in above-mentioned anti-theft bolt and the screw-thread fit of left-hand thread tapped blind hole.
spanner termination in above-mentioned anti-theft bolt is provided with one-level step conical clear opening, and the conical surface is provided with two symmetrical pillars, and the other end is pommel handle.
the beneficial effects of the utility model are: novel structure; easy to operate; can effectively prevent that valve, the stolen phenomenon of equipment from occurring; guarantee that oil field normally produces; improve oilfield economic benefit and field management level; avoid into oil, gas, Water Energy leak protection environment, alleviate post workman's labor intensity.
Accompanying drawing explanation
the main complete section structural representation of looking of the on-the-spot application of Fig. 1-the utility model.
the master of Fig. 2-the utility model spanner 6 looks partial cutaway structural representation.
in figure, 1. screw rod, 2. nut, 3. auxiliary screw rod, 4. parts, 5. cup head, 6. spanner, 7. pillar; A. post hole, B. tapering clear opening, C. left-hand thread tapped blind hole.
Embodiment
below in conjunction with accompanying drawing, enforcement of the present utility model is further elaborated:
anti-theft bolt is comprised of screw rod 1, nut 2, auxiliary screw rod 3, spanner 6.Screw rod 1 one end of its anti-theft bolt is provided with cup head 5, and the other end is provided with left-hand thread tapped blind hole C, and on have nut 2.During use, first screw rod 1 is passed to the bolt hole of parts 4, the nut 2 of screwing on; Secondly, by spanner 6 termination tapering clear opening B
be enclosed within on nut 2, make pillar 7 insert post hole A, entering left-hand thread tapped blind hole (C) on auxiliary screw rod 3; The 3rd, with spanner, come to a halt and assist screw rod 3, clockwise rotating spanner 6 can tighten nut 2; The 4th, will assist screw rod 3 to unload.Without spanner 6 and auxiliary screw rod 3, nut 2 can not be laid down, thereby play anti-theft function.
