Abstract
The utility model discloses a spiral telescopic pull rod device, which is mainly composed of a pull rod, a lock nut, a screw rod, a U-shaped steel bar, a right-angle oblique plug, regulating holes and steel bar card U notches, wherein the pull rod is a round steel tube, threads are arranged in the two ends of the round steel tube, one end is provided with right-hand threads while the other end is provided with left-hand threads, four regulating holes are uniformly distributed in the circumference in the middle part of the round steel tube, two ends of the round steel tube are respectively connected with one end of the screw rod, the lock nut is arranged on the screw rod, the other end of the screw rod is connected with the U-shaped steel bar, which is a rectangle steel plate and is provided with a square hole in the middle, one end, farther away from the screw rod, of the square hole is provided with the steel bar card U notch, one end, closer to the screw rod, of the square hole is provided with the right-angle oblique plug, and two right-angle sides of the right-angle oblique plug are close to two right-angle sides of the square hole. By adopting the spiral telescopic pull rod device, disclosed by the utility model, the problem of difficult connection by ordinary pull rods due to the different spaces between shed frames is solved, the shed frames are interlocked, the stability and safety of sheds are enhanced, the construction process is simplified, and the operation of workers is facilitated.
Description
Technical field
The utility model relates to a kind of mechanical device, relates in particular to a kind of adjustable mechanical draw rod device.
Background technology
While connecting fastening U steel frame with common pull bar, because frame spacing has error, usually cause difficulty during connection, time-consuming effort again, therefore, improves draw rod device very helpful to improving frame installation effectiveness and construction safety.
Summary of the invention
In order to make up the deficiencies in the prior art, solving spacing has error, and common pull bar causes difficult problem while connecting, and has designed spiral expanding formula draw rod device.
The technical scheme in the invention for solving the technical problem can be:
Spiral expanding formula draw rod device, mainly by pull bar, locking nut, lead screw, U steel Ka Lan, right angle is tiltedly filled in, adjustment hole and U steel card hurdle notch form, pull bar described in it is round steel pipe, inside, round steel pipe two ends is provided with screw thread, one end is right-handed thread, one end is left-hand thread screw thread, uniform on the circumference of round steel pipe middle part four adjustment holes are set, round steel pipe two ends are connecting screw bar one end respectively, in lead screw, be provided with locking nut, the lead screw other end connects U steel Ka Lan, U steel Ka Lan is rectangle steel plate, centre is provided with square hole, square hole is provided with U steel card hurdle notch apart from a lead screw side far away, square hole is provided with right angle apart from the nearlyer side of lead screw and tiltedly fills in, two right-angle sides are tiltedly filled near square hole two right-angle sides in right angle.
The beneficial effects of the utility model are:
1, the utility model has solved because frame spacing is different, with common pull bar, connects difficult problem, makes support interlocking, has strengthened steadiness and the safety of shed, has simplified working procedure, has facilitated workman's operation.
2, the utility model simplicity of design, easy to manufacture, with low cost.
