Abstract
The utility model discloses a kind of Simple pulley formula reinforcement reinforced shear, adopt the assembly pulley simplified to be common with the addition of force-increasing mechanism to blade reinforced shear, improve the shearing force of traditional manual to blade reinforced shear.Structure is simple, easy to use, with low cost, does not use any energy.Can be widely applied in the shearing work of metal wire rod.
Description
Technical field
The utility model relates to a kind of bar cutting instrument, particularly a kind of Simple pulley formula reinforcement reinforced shear.
Background technology
In building, machinery, rescue industry, bar cutting instrument is used to cut off the metal wire rod such as reinforcing bar, cable widely.Current known bar cutting instrument has several as follows: (1) manual steel bar is cut, normally common to blade scissors.This scissors utilizes simple lever principle to carry out reinforcement, and shearing force is less, and volume is large; Be not suitable for the more weak people of muscle power to use.(2) hand-hydraulic reinforced shear, this scissors has the large advantage of shearing with common compared with blade scissors, but complex structure, and hydraulic oil is easily revealed, and safeguard inconvenient, cost is also higher.(3) bar cutter, the energy that employing electric energy etc. are extra, shearing force is large.But complex structure, cost is high.The advantages and disadvantages of comprehensive above-mentioned reinforcing bar reinforcing bar cutting implement, is necessary to propose a kind of structure simple, does not need additional energy source, can realize the bar cutting instrument being convenient to safeguard of larger force increasing ratio with less volume simultaneously.This bar cutting instrument is used to increase work efficiency, energy-conserving and environment-protective simultaneously, cost-saving.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model proposes a kind of Simple pulley formula reinforcement reinforced shear.Its structure is simple, easy to use, is easy to safeguard.
The utility model solves the technical scheme that its technical problem adopts: a kind of Simple pulley formula reinforcement reinforced shear, comprise blade scissors, frame, limitting casing, limiting plate, take-up handle, take-up handle installation shaft, two nylon rope supports, nylon rope and force pins; Wherein, described hinged one end being fixed to frame of the two panels blade to blade scissors, limiting plate is arranged on the other end of frame, and take-up handle installation shaft is arranged on limiting plate, and take-up handle is hinged in take-up handle installation shaft; Limitting casing is arranged in frame; Limitting casing is passed to two handles of blade scissors; Limitting casing and limiting plate have relative dovetail groove, and the two ends of nylon rope support are embedded in the dovetail groove of limitting casing and the dovetail groove of limiting plate respectively; Limiting plate has nylon rope guide channel; Two nylon rope supports all have several through wires holes, and nylon rope one end and first through wires hole are fixed, the other end is staggered through after the through wires hole on two nylon rope supports successively, are wound on take-up handle through nylon rope guide channel; Chute is had on two handles of blade scissors; Force pin is hinged on nylon rope support, and is embedded in chute.
The beneficial effects of the utility model are: the utility model adopts the assembly pulley simplified to be common with the addition of force-increasing mechanism to blade reinforced shear, improves the shearing force of traditional reinforced shear.Structure is simple, easy to use, with low cost, does not use any energy.Can be widely applied in the shearing work of metal wire rod.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The utility model adopts the assembly pulley (through wires hole) simplified to carry out reinforcement, improves the shearing force of traditional reinforced shear.As shown in Figure 1, a kind of Simple pulley formula reinforcement reinforced shear, comprises blade scissors 1, frame 2, limitting casing 7, limiting plate 8, take-up handle 4, take-up handle installation shaft 9, two nylon rope supports 3, nylon rope 5, force pin 13.
As shown in Figure 2, to the hinged one end being fixed to frame 2 of the two panels blade of blade scissors 1, limiting plate 8 is arranged on the other end of frame 2, and take-up handle installation shaft 9 is arranged on limiting plate 8, and take-up handle 4 is hinged in take-up handle installation shaft 9; Limitting casing 7 is arranged in frame 2, for installing nylon rope support 3; Limitting casing 7 is passed to two handles of blade scissors 1;
As shown in Figure 6, limitting casing 7 has relative dovetail groove with limiting plate 8, and the two ends of nylon rope support 3 are embedded in the dovetail groove of limitting casing 7 and the dovetail groove of limiting plate 8 respectively; Limiting plate 8 has nylon rope guide channel 10; As shown in Figure 3, nylon rope support 3 has several through wires holes 12, nylon rope 5 one end and first through wires hole 12 are fixed, and interlock successively through the through wires hole 12(on two nylon rope supports first through first through wires hole 12 on first nylon rope support 3, again through first through wires hole 12 on second nylon rope support 3, then through second through wires hole 12 on second through wires hole, 12, second the nylon rope support 3 on first nylon rope support 3 ...), form an assembly pulley simplified.The other end, through nylon rope guide channel 10, is wound on take-up handle 4.
In order to ensure the hot strength of nylon rope 5, nylon rope can be the polyamide-fiber nylon rope of 9mm to 10mm with diameter.
As shown in Figure 3 and Figure 4, have chute 15 on two handles of blade scissors 1, force pin 13 is hinged on nylon rope support 3, and is embedded in chute 15.
The course of work of the present utility model is as follows: when rotary wire-reeling handle 4, nylon rope 5 tightens up, and pulls nylon rope support 3.Nylon rope support 3 slide in opposition in dovetail groove, by force pin 13 by the pull transfer of nylon rope 5 on scissors handle, make to make shear action to blade scissors.Owing to there being multiply nylon rope between nylon rope, according to the reinforcement principle of assembly pulley, power can be amplified by pulley force-increasing mechanism, reaches the object improving original shearing force to blade reinforced shear.
