Abstract

The utility model relates to a pair of plastic pipeline scissors, which comprises scissor handles and knife blades. The utility model is characterized in that a connecting rod mechanism of a toothed bar is arranged between the scissor handles; one end of toothed bar is positioned at the upper end of the left scissor handle by a screw bolt; both ends of a connecting rod are respectively connected with the toothed bar and the inner part of a positioning slot in a pinning mode; the tail part of the knife blade is provided with a small tooth which can be engaged with the toothed bar; the screw bolt is provided with a restoring spring. The utility model is mainly used for shearing plastic (or similar section materials) pipelines. The utility model has the significant advantages of time saving, labor saving, convenient operation, safety, sanitation and good shearing effect. Simultaneously, the utility model is not limited by environment and space and is an ideal tool for shearing the pipelines.

Description

Plastic pipe scissors

The utility model provides a kind of plastic conduit scissors, belongs to cutting implement.

At present, the shearing of plastic conduit generally is to adopt original sawed-off method (manual or electronic), the major defect of this method be time-consuming, require great effort, be subjected to spatial constraints, operate more loaded down with trivial details, and danger, accident-proneness.Simultaneously, sawed-off face has overlap, burr, thereby influences the flow velocity of liquid, and produces a lot of smear metal contaminated environment.Still the special-purpose cutting implement that is used for plastic conduit that lacks a kind of maturation in the prior art.

The purpose of this utility model is to provide a kind of special-purpose cutting implement that plastic conduit is sheared that is mainly used at above-mentioned deficiency, to overcome the deficiencies in the prior art.

Technical solution of the present utility model is: this scissors still comprises left and right handle and the blade cut, be characterized in being provided with a tooth bar linkage left and right cutting between the handle, wherein, one end of tooth bar is positioned a left side by bolt and cuts an inboard, upper end, one end of connecting rod is pinned in the locating slot on the tooth bar, the other end is pinned in the locating slot of blade bottom, and blade is positioned the right side by bolt and cuts last, and its afterbody has a little tooth that can be meshed with tooth bar; Left and right cutting being connected by bolt is equipped with back-moving spring on this bolt and tooth bar bolt.

The utility model is described in further detail below in conjunction with the accompanying drawing illustrated embodiment.

Among the figure, the 1-lock ring, 2-cuts handle in a left side, 3-back-moving spring, 4-positioning sleeve, 5-bolt, the 6-back-moving spring, 7-positioning sleeve, 8-bolt, 9-pin, 10-blade, 11-damping spring, the 12-bolt, the 13-nut, the 14-connecting rod, the 15-tooth bar, 16-cuts handle in the right side.

With reference to accompanying drawing, the utility model is formed by cutting handle, tooth bar connecting rod and blade three parts, wherein, cut and (2) and the right side are cut (16) comprising that a left side that is connected by bolt (8) is cut, it is convex structure so that will wait to cut the pipe location that the right side is cut the top of (16), and has groove so that place blade (10); The tooth bar shaft portion comprises tooth bar (15) and connecting rod (14), wherein, tooth bar (15) upper end is positioned a left side by bolt (5) and cuts (2) upper end inboard, connecting rod (14) contains two, and its two ends are pinned at respectively in the bar shaped locating slot of tooth bar (15) top and blade (10) bottom; Blade (10) is fixed in the right side by bolt (12) to be cut (16) top, and its afterbody has one can go up the little tooth that cloudy tooth is meshed with tooth bar (15).On bolt (5), (8), be respectively equipped with positioning sleeve (4), (7), outside positioning sleeve (4), (7) back-moving spring (3), (6) be housed respectively, promptly be provided with positioning sleeve between bolt and the spring.

For slowing down blade (10) swing in the course of the work, on the blade bolt, be provided with damping spring (11); In addition, cut end is provided with lock ring (1), be convenient to locking and carry.

Before the scissors work, earlier left and right cutting separated (2), (16) to both sides, make the little tooth of blade (10) afterbody and first cloudy tooth engagement of tooth bar (15) upper end, at this moment scissors is in maximum shear diameter state, and the two ends that is to say connecting rod (14) lay respectively at tooth bar locating slot and blade locating slot bottom.Pinch with hand and to cut (one hand), back-moving spring (3) just makes tooth bar (15) move right, at this moment the little tooth of blade (10) the afterbody tooth of tooth bar (15) of passing by, under the constraint of connecting rod (14), blade (10) is the axle center with bolt (12), do rotating counterclockwise, clip is diminished, promptly finish the first element of shearing.The rest may be inferred, and reciprocal eight times altogether (are the little tooth of blade afterbody pass by eight teeth of tooth bar) have just finished whole shear action.

Remarkable advantage of the present utility model is easy to operate, save time (only needing for tens seconds), laborsaving (only needing the power of a hand of people), is not subjected to the restriction in environment, space, and handling safety, is without fear of an attack from the rear. Simultaneously, shear effect is good, and section is smooth, non-trimming, and no burr, flawless, the plastic-less deformation does not have smear metal, non-environmental-pollution during shearing. In addition, the characteristics such as that the utility model also has is simple in structure, volume is small and exquisite, easy to carry, except plastic conduit, the pipeline that also can be used for similar section bar is sheared, really a kind of desirable pipeline cutting implement.

Claims

1, a kind of plastic conduit scissors, comprise left and right the cutting that links to each other by bolt (8) (2), (16) and blade (10), it is characterized in that two cut between be provided with the tooth bar linkage, wherein, tooth bar (15) one ends are positioned a left side by bolt (5) and cut (2) upper end, and the two ends of connecting rod (14) are pinned at respectively in tooth bar locating slot and the blade locating slot; Blade (10) is connected in the right side by bolt (12) and cuts in (16), and its afterbody has a little tooth that can be meshed with tooth bar (15); Back-moving spring (3), (6) are housed respectively on bolt (5), (8);
