New reinforcing steel bar Bundling hook
Technical field
The present invention relates to a kind of building implement, be specifically related to a kind of new reinforcing steel bar Bundling hook bundling reinforcing bar.
Background technology
Tying up of reinforcing bar is all often adopt tied silk, and with using reinforcing steel bar binding hook during tied silk wiretie, thus reinforcing steel bar binding hook is as a kind of special tool, widely uses on building sites.Its structure of existing reinforcing steel bar binding hook is one end is mostly handle, and the other end is forniciform tip composition, by the hook-shaped position on tip, catches on tied silk, and rotate reinforcing steel bar binding hook, tied silk can be firm by reinforced-bar binding.In traditional method, concrete reinforcement worker adopts the colligation of Bundling hook manpower, and labour intensity is large, and the hand holding Bundling hook repeats same action repeatedly, and workman's fatiguability, affects efficiency.Also have in prior art and adopt motor to drive Bundling hook, but tied silk is very easily twisted off, motor drives Bundling hook not easily to control the angle that Bundling hook turns over, and thus tied silk is very easily twisted off, and affects manufacturing cost and production time.
Summary of the invention
The object of the present invention is to provide a kind of new reinforcing steel bar Bundling hook.
For achieving the above object, technical scheme of the present invention is:
A kind of new reinforcing steel bar Bundling hook, comprise Bundling hook, it is characterized in that: also comprise Bundling hook drive unit, Bundling hook drive unit comprises housing, briquetting, crankshaft connecting rod system, worm gear and worm screw, and briquetting one end is fixed on housing by axle, and its other end is can around the free end of central axis, the connecting rod of crankshaft connecting rod system is connected with the free end of briquetting, the bent axle of crankshaft connecting rod system is connected with worm gear, and worm gear and worm engaging, worm screw is connected with Bundling hook.
Further, speed changer is connected with between worm screw and Bundling hook.
Beneficial effect of the present invention is:
1, briquetting is pressed, drive crankshaft connecting rod system moves, and finally cause worm and gear to rotate, Bundling hook rotates together along with worm screw, by tied silk, binding reinforcing bars is firm, traditional hand-turning Bundling hook is replaced by pressing briquetting, reduce the labour intensity of constructor, also improve the efficiency of construction of reinforced bar binding wire binding simultaneously, easy to operate, quick, and the angle by regulating the gearratio between worm and gear and adjustable Bundling hook to turn over, angle easily controls, and makes binding reinforcing bar be that tied silk is not easily broken.
2, be connected with speed changer between worm screw and Bundling hook, the angle regulating Bundling hook to turn over by speed changer, make binding reinforcing bar be that tied silk is not easily broken.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein Reference numeral is: 1-Bundling hook, 2-housing, 3-briquetting, 4-connecting rod, 5-bent axle, 6-worm gear, 7-worm screw, 8-speed changer.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described:
As shown in Figure 1, a kind of new reinforcing steel bar Bundling hook, comprises Bundling hook 1 and Bundling hook drive unit, and Bundling hook drive unit is connected with Bundling hook 1 and drives Bundling hook 1 to rotate, and tightens on reinforcing bar by rotating Bundling hook 1 by tied silk, and binding reinforcing bars is firm.
Described Bundling hook drive unit comprises the Worm Wheel System system (6,7) of crankshaft connecting rod system (4,5), worm gear 6 and worm screw 7 composition that housing 2, briquetting 3, bent axle 5 and connecting rod 4 form.Briquetting 3 one end is fixed in housing 2 by axle, and the other end is free end, and this free end freely can rotate around axle, and the contact surface of this briquetting 3 and palm contacts is higher than the upper surface of housing 2.The connecting rod 4 of crankshaft connecting rod system (4,5) is connected with the free end of briquetting 3, and the contact surface be connected with the connecting rod 4 of crankshaft connecting rod system (4,5) in briquetting 3 is bending guide-track groove, and one end of connecting rod 4 can be free to slide in the guide-track groove of the free end of briquetting 3.Connecting rod 4 is made up of two parts, these two parts are connected by screw and form crankshaft connecting rod system (4,5) together with bent axles 5, the bent axle 5 of crankshaft connecting rod system (4,5) is connected with worm gear 6, worm gear 6 engages with worm screw 7, worm screw 7 is connected with Bundling hook 1, is connected with speed changer 8 between worm screw 7 and Bundling hook 1.
During the work of new reinforcing steel bar Bundling hook, briquetting 3 is pressed downwards with hand, the connecting rod 4 moving downward driving crank linkage (4,5) of briquetting 3 moves downward, thus driving crank 5 rotates, bent axle 5 drives worm gear 6 to rotate, worm gear 6 drives the worm screw 7 be meshed with it to rotate, and drives Bundling hook 1 to rotate together, thus realizes binding reinforcing bars is firm.
The present invention replaces traditional hand-turning Bundling hook by pressing briquetting, reduce the labour intensity of constructor, also improve the efficiency of construction of reinforced bar binding wire binding simultaneously, easy to operate, quick, and the angle by regulating the gearratio between worm and gear and adjustable Bundling hook to turn over, angle easily controls, and when making to bundle reinforcing bar, tied silk is not easily broken; Be connected with speed changer between worm screw and Bundling hook, regulate Bundling hook to turn over suitable angle by speed changer, make binding reinforcing bar be that tied silk is not easily broken.
