Abstract
The utility model discloses a rigid pulling hook of twisted steel, which comprises a flange and two pulling hooks. The utility model is characterized in that the left and right pulling hook are of twisted steel without longitudinal ribs. One end of the left-hand twisted steel without longitudinal ribs and the right-hand twisted steel without longitudinal ribs are bent into semi circle, so that they look like fishing hooks. The straight rods of the two pulling hooks are screwed into the left-hand nut and the right-hand nut from left and right end of the flange. The utility model is easy to make, of low production cost, free from any machined weak face, of high mechanical strength; easy and convenient to operate, and can reduce labor intensity of users and improve productivity.
Description
Technical field
The utility model relates to a kind of machanical fastener equipment, specifically, relates to a kind of general fastening piece of adopting in colliery that is used for.
Background technique
At present, at the rigidity drag hook that the colliery is general in adopting many kinds are arranged, and differ from one another.Because its specification is little, intensity is low, but poor stability, and screw thread is thin very easily causes drag hook to be difficult to turn because of carbon deposit in the screw thread and reason such as get rusty, and increases operator's labor intensity, reduces working efficiency, shortens the working life of drag hook such as old-fashioned drag hook.Occurred some new-type drag hooks afterwards, its specification is big, easy to operate, long service life, but its processing technology complexity, cost of material and processing cost are higher, and relatively heavy.And bolt-type drag hook poor rigidity, intensity are low, fragile, working life is short, and in use scratch staff easily causes industrial accident.
Summary of the invention
The utility model is just in order to solve the above-mentioned technical problem that the rigidity drag hook exists, and a kind of novel Deformed Steel Bars rigidity drag hook that is similar to Hua Lan of development.
The technological scheme that its technical problem that solves the utility model adopts is: Deformed Steel Bars rigidity drag hook comprises Hua Lan and two drag hooks; It is characterized in that: a drag hook adopts left-handed nothing to indulge the muscle Deformed Steel Bars, and another drag hook adopts dextrorotation not have vertical muscle Deformed Steel Bars, and an end that the vertical muscle Deformed Steel Bars of left-handed nothing and dextrorotation is not had vertical muscle Deformed Steel Bars curves semicircle, makes its adult fish hook shape; Spending blue frame to be rectangle, is respectively left-handed nut and the right-handed nut who is complementary with the drag hook screw thread in the intermediate vertical position of two minor face; The straight-bar of two drag hooks is screwed into left-handed nut and the right-handed nut from two ends, the left and right sides respectively.Its feature also is: the diameter that does not have vertical muscle Deformed Steel Bars is between 16 millimeters to 26 millimeters.
The beneficial effects of the utility model are that Deformed Steel Bars rigidity drag hook need not special machining screw, make simply, and cost of production is low; Drag hook utilizes the screw thread of himself, does not need out silk, does not have the processing plane of weakness, the mechanical strength height; The screw bolt and nut matching gap is bigger, and pitch is also bigger, so screw thread is difficult for being stopped up long service life by charcoal or iron rust in the using process; Simple to operation, can reduce user's labor intensity, increase work efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, the utility model Deformed Steel Bars rigidity drag hook comprises Hua Lan 1 and two drag hooks 2,3; Left side drag hook 2 adopts the vertical muscle Deformed Steel Bars of left-handed nothing, and the right drag hook 3 adopts dextrorotation not have vertical muscle Deformed Steel Bars, and an end that the vertical muscle Deformed Steel Bars 2 of left-handed nothing and dextrorotation is not had vertical muscle Deformed Steel Bars 3 curves semicircle, makes its adult fish hook shape; Spending blue 1 frame to be rectangle, is respectively left-handed nut 4 and the right-handed nut 5 who is complementary with the drag hook screw thread in the intermediate vertical position of two minor face; The straight- bar 6,7 of two drag hooks is screwed into left-handed nut 4 and the right-handed nut 5 from two ends, the left and right sides respectively.It is 20 millimeters that vertical muscle Deformed Steel Bars of left-handed nothing and dextrorotation do not have vertical its diameter of muscle Deformed Steel Bars, also can select the vertical muscle Deformed Steel Bars of nothing between 16 millimeters to 26 millimeters as required for use.
Claims (2)
1, a kind of Deformed Steel Bars rigidity drag hook comprises Hua Lan and two drag hooks; It is characterized in that: a drag hook adopts left-handed nothing to indulge the muscle Deformed Steel Bars, and another drag hook adopts dextrorotation not have vertical muscle Deformed Steel Bars, and an end that the vertical muscle Deformed Steel Bars of left-handed nothing and dextrorotation is not had vertical muscle Deformed Steel Bars curves semicircle, makes its adult fish hook shape; Spending blue frame to be rectangle, is respectively left-handed nut and the right-handed nut who is complementary with the drag hook screw thread in the intermediate vertical position of two minor face; The straight-bar of two drag hooks is screwed into left-handed nut and the right-handed nut from two ends, the left and right sides respectively.
