Abstract
The utility model provides a pair of miniature shears. The miniature shears are provided with a cylinder body, wherein one end of the cylinder body is communicated with hydraulic oil through a quick coupling, the other end of the cylinder body is connected with a cylinder cover in a sealed mode, and one end of a piston rod stretches out of the cylinder cover and is connected with the upper right portion of movable shears; the rear of static shears is hinged to the rear of the cylinder cover, the lower portion of the movable shears and the front of the static shears are hinged to the front of the cylinder cover through a hinge pin A, the outer diameter of the piston rod is sleeved with a compressed spring, and a cavity is formed between the rear end face of the piston rod and the bottom surface of a cylinder body hole. The miniature shears are simple in structure, light in weight, low in price and particularly suitable for shearing operation at any angle in a narrow space, and greatly improves working efficiency of emergency rescue.
Description
Technical field
The utility model belongs to rescue and relief work equipment technical field, is specifically related to a kind of micro-scissors.
Background technology
Along with the fast development of Chinese national economy and urban construction, various natural calamities, serious accident happen occasionally, and the people's lives and property is subject to serious threat.For this reason, both at home and abroad all having done a large amount of work aspect the research of rescue and relief work instrument, develop into modern pneumatic tool, hydraulic tool, ultrahigh-pressure hydraulic instrument from initial hand tools, kind, the function of product also become better and approaching perfection day by day.Hydraulic pressure scissors is that the useful of conventional hydraulic rescue tool supplemented, support the use with manual pump, mainly use with rescue site limited space, cannot use the occasion of conventional hydraulic tool, existing hydraulic shear knife structure complexity, bulky, in small space, cannot complete shearing work, therefore be necessary to propose to improve.
Utility model content
The technical problem that the utility model solves: a kind of micro-scissors is provided, efficiently solves the problem that in small space, conventional magnetic shear device cannot be sheared more greatly due to volume, improved the ability of rescue personnel's rescue and relief work.
The technical solution adopted in the utility model: micro-scissors, there is cylinder body, described cylinder body one end is communicated with hydraulic oil by snap joint, and the cylinder body other end and cylinder cap are tightly connected, and piston rod one end stretches out cylinder cap and moving scissors upper right quarter is hinged; Quiet scissors rear portion and cylinder cap rear portion are hinged, and described moving scissors bottom and quiet scissors front portion are all hinged by bearing pin A and cylinder cap front portion, on described piston rod external diameter, are set with stage clip, and piston rod rear end face and cylinder bore bottom surface form cavity.
Further, described cylinder cap entirety is U-shaped, and cylinder cap top is shaped with the internal thread screwing with cylinder body cylindrical and the endoporus passing through for piston rod, and cylinder cap bottom is shaped with U-shaped groove, and described quiet scissors is included in U-shaped groove also hinged by bearing pin B and cylinder cap rear portion.
Further, described piston rod front end and moving scissors upper left quarter are hinged by bearing pin C.
Further, described compression spring sleeve is contained in the annular chamber that piston rod and cylinder body form.
The utility model is compared with prior art simple in structure, and volume is little, lightweight, cheap, is particularly useful for the arbitrarily angled shearing work of small space, has improved greatly the operating efficiency of rescue.

Detailed description of the invention
Below in conjunction with accompanying drawing 1-5, a kind of embodiment of the present utility model is described.
Micro-scissors, has cylinder body 8, and described cylinder body 8 one end are communicated with hydraulic oil by snap joint 3, and cylinder body 8 other ends and cylinder cap 4 are tightly connected, and it is hinged by bearing pin C with moving scissors 2 upper right quarters that cylinder cap 4 is stretched out in piston rod 7 one end; Quiet scissors 1 rear portion and cylinder cap 4 rear portions are hinged, described moving scissors 2 bottoms and quiet scissors 1 front portion are all anterior hinged by bearing pin A and cylinder cap 4, specifically, described cylinder cap 4 entirety are U-shaped, cylinder cap 4 tops are shaped with the internal thread 9 screwing with cylinder body 8 cylindricals and the endoporus 10 passing through for piston rod 7, cylinder cap 4 bottoms are shaped with U-shaped groove 11, and described quiet scissors 1 is included in U-shaped groove 11 also hinged by bearing pin B and cylinder cap 4 rear portions.On described piston rod 7 external diameters, be set with stage clip 6, described stage clip 6 is sleeved in the annular chamber that piston rod 7 and cylinder body 8 form, piston rod 7 rear end faces and cylinder body 8 bottom surfaces, hole formation cavitys 5.
Operation principle: hydraulic oil, in snap joint 3 enters the cavity 5 of piston rod 7, promotes piston rod 7 protruding, and the moving scissors 2 that is hinged on piston rod 7 front ends rotates taking bearing pin A as fulcrum, makes two edge of a knife closures, completes shearing work; Hydraulic oil pump off-load, piston rod 7 is return under the effect of stage clip 6, drives moving scissors 2 to open, and completes one action circulation.
The utility model adopts 63MPa ultrahigh-pressure hydraulic technology, the technical state-of-the-art technology of gathering the subjects such as machinery, hydraulic pressure, material, heat treatment, described moving scissors 2 and quiet scissors 1 all adopt high strength alloy steel to forge, and through special thermal treatment, scissors all can carry in whole length range.
The utility model utilizes the feature that its volume is little, lightweight, shear ability strong, individual soldier's operation can complete shearing work, and rescue is confined in the victim in constrained environment or rescues the pest that is subject in hazardous environment, reaches the object of rescue or the disaster relief.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, and the equivalence of being done with content described in the utility model claim therefore all changes, within all should being included in the utility model claim scope.
