Description
Technical field
The present invention 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, cut off the metal wire rod such as reinforcing bar, cable with bar cutting instrument widely. Current known bar cutting instrument has several as follows: (1) manual steel bar is cut, normally common tool setting formula scissors. The simple lever principle of this scissors utilization is carried out reinforcement, and shearing force is less, and volume is large; Being not suitable for the weak people of muscle power uses. (2) hand-hydraulic reinforced shear, this scissors has advantages of that shearing is large compared with common tool setting formula scissors, but complex structure, and hydraulic oil easily reveals, and safeguards inconveniently, cost is also higher. (3) bar cutter, adopts the extra energy such as electric energy, and 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 one simple in structure, does not need additional energy source, can realize with less volume the bar cutting instrument of being convenient to maintenance of larger force increasing ratio simultaneously. Use this bar cutting instrument 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 present invention proposes a kind of Simple pulley formula reinforcement reinforced shear. It is simple in structure, easy to use, is easy to safeguard.
The technical solution adopted for the present invention to solve the technical problems is: a kind of Simple pulley formula reinforcement reinforced shear, comprises tool setting formula scissors, frame, limitting casing, limiting plate, take-up handle, take-up handle installation shaft, two nylon rope supports, nylon rope and application of force pins; Wherein, hinged one end that is fixed to frame of two blades of described tool setting formula 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; Two handles of tool setting formula scissors are through limitting casing; Limitting casing has relative dovetail groove with limiting plate, and the two ends of nylon rope support are embedded in respectively in the dovetail groove of limitting casing and the dovetail groove of limiting plate; On limiting plate, have nylon rope guide channel; On two nylon rope supports, all have several through wires holes, nylon rope one end and first through wires hole are fixed, and the other end is staggered through after the through wires hole on two nylon rope supports successively, passes nylon rope guide channel and is wound on take-up handle; On two handles of tool setting formula scissors, have chute; Application of force pin is hinged on nylon rope support, and is embedded in chute.
Beneficial effect of the present invention is: it is that common tool setting formula reinforced shear has added force-increasing mechanism that the present invention adopts the assembly pulley of simplification, has improved the shearing force of traditional reinforced shear. Simple in structure, easy to use, with low cost, do 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 invention will be further described.
The present invention adopts the assembly pulley (through wires hole) of simplification to carry out reinforcement, has improved the shearing force of traditional reinforced shear. As shown in Figure 1, a kind of Simple pulley formula reinforcement reinforced shear, comprises tool setting formula scissors 1, frame 2, limitting casing 7, limiting plate 8, take-up handle 4,9, two nylon rope supports 3 of take-up handle installation shaft, nylon rope 5, application of force pin 13.
As shown in Figure 2, hinged one end that is fixed to frame 2 of two blades of tool setting formula 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 nylon rope support 3 is installed; Two handles of tool setting formula scissors 1 are through limitting casing 7;
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 respectively in the dovetail groove of limitting casing 7 and the dovetail groove of limiting plate 8; On limiting plate 8, have 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 fixing, 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 on first nylon rope support 3, second nylon rope support 3 ...), the assembly pulley of a simplification of formation. 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, on two handles of tool setting formula scissors 1, have chute 15, application of force pin 13 is hinged on nylon rope support 3, and is embedded in chute 15.
The course of work of the present invention is as follows: in the time of 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, is delivered to the pulling force of nylon rope 5 on scissors handle by application of force pin 13, makes tool setting formula scissors make shear action. Owing to there being multiply nylon rope between nylon rope, according to the reinforcement principle of assembly pulley, pulley force-increasing mechanism can amplify power, has reached the object of the shearing force that improves original tool setting formula reinforced shear.
