Description
Technical field
The utility model relates to the pipe cutter of a kind of cutter, particularly a kind of plastic conduit, is applicable to the cutting work of PVC plastic tube.
Background technology
At present, the application of PVC plastic tube is very common, and installation personnel needs the PVC plastic tube with whole to cut into suitable length, is convenient to construction.Existing P VC plastic tube cutting tool is similar to the structure of scissors, and there are several shortcomings in this structure: 1, because body has elasticity, easily pipe fitting is flattened during shearing, and can not recover fully after the distortion; Can not cut into when 2, just having begun, when reinforcing reaches enough big, cut the inlet pipe body again suddenly,, cause and cut the phenomenon that produces oblique otch partially so be difficult to the cut direction of control blade owing to blade; 3, owing to body surface smoother, the easy slippage of blade when firmly shearing produces the danger of hindering hand.In addition, existing copper pipe cutter blade is circular, is unfavorable for cutting plastic tube.
Summary of the invention
The technical problems to be solved in the utility model is: at the problems referred to above, provide a kind of pipe cutter of safe in utilization, easy to operate plastic conduit, this cutter can be controlled cut direction and depth of cut easily, and the plastic tube after the cutting can not be out of shape.
The technical scheme that the utility model adopted is: a kind of pipe cutter of plastic conduit, it is characterized in that: it comprises the main frame of similar spanner shape, its head has the U-shaped opening, the frame body has cavity, the frame tail is equipped with handwheel, three rollers and blades at grade, rectangular four point locations are housed in the U-shaped opening of main frame, and one of them roller and blade are connected with the handwheel of frame tail by an interlinked mechanism.
Described interlinked mechanism comprises with adjustable shelf, the screw mandrel of the roller pin joint of blade and homonymy and is enclosed within the clamp nut on the screw mandrel and discharges nut, wherein, adjustable shelf has a link that has vertical through holes, perpendicular to the level of this vertical through holes to horizontal through hole that is equipped with coaxial line and blind hole, described screw mandrel one end passes horizontal through hole and puts in the blind hole, and the screw mandrel other end is connected with handwheel by the handwheel pin; Be with spring on the screw mandrel; The installed inside that has the link of horizontal through hole discharges nut, an end of the corresponding spring in the outside of this link, and the other end of spring is installed clamp nut.
Leave adjustable gap between the tail end of described main frame and the handwheel.
The thread rotary orientation of described release nut and clamp nut and screw mandrel is left-handed.
The beneficial effects of the utility model are: the main frame of this pipe cutter is the spanner shape, the roller and the blade of rectangular four point locations are installed in the U-shaped opening of main frame head, at the frame tail handwheel is installed, is linked to each other by the interlinked mechanism in the frame body cavity between handwheel and the blade.Rotation by handwheel just can be driven in the blade incision plastic tube by interlinked mechanism, the roller of rectangular four point locations and blade can effectively block firm plastic tube to be cut (only allowing pipe cutter to center on plastic tube does circumferentially to rotate), on the one hand can avoid the blade slippage and produce and hinder the hand accident, can avoid the blade cuts direction deviation to occur on the other hand; In addition, can adapt to the plastic tube to be cut of different-diameter, with the depth of cut of control blade by adjusting handle.Rotate a circle whole pipe cutter this moment, just cut-out that can plastic tube is level and smooth, the phenomenon of having avoided plastic tube to be crushed easily and to be out of shape when cutting; Easy to operate, safe and practical.
Description of drawings
Fig. 1 is the main cutaway view of the utility model embodiment.
Fig. 2 is the stereogram of the utility model embodiment.
The specific embodiment
As shown in Figure 1 and Figure 2, the pipe cutter of present embodiment plastic conduit comprises main frame 3, the similar spanner shape of the shape of this main frame, its head has a U-shaped opening, the frame body is offered cavity and interlinked mechanism is installed in the chamber, the frame tail is installed the handwheel 13 that links to each other with interlinked mechanism one end, and leaves adjustable gap (passing through threaded engagement) between handwheel 13 and main frame 3 tail ends.Three rollers 1 and bar blade 4, four rectangular layouts in the same plane are housed in the described U-shaped opening, and wherein two rollers 1 are installed in an inboard of U-shaped opening by roller pin 2; A blade 4 and a remaining roller 1 are positioned at another inboard of U-shaped opening, are installed in the other end of described interlinked mechanism respectively by blade pin 5 and roller pin 2.
The concrete structure of above-mentioned interlinked mechanism is as follows: it comprises screw mandrel 11, is installed in the adjustable shelf 6 of this screw mandrel end, and is enclosed within clamp nut 9, release nut 7 and spring 8 on this screw mandrel body of rod.Roller 1 pin joint of above-mentioned blade 4 and this blade homonymy is at an end of adjustable shelf 6, the adjustable shelf other end is the link that links to each other with screw mandrel 11, be equipped with a vertical through holes 6-1, a horizontal through hole 6-2 and a blind hole 6-3 in this link, described horizontal through hole is vertical with vertical through holes with blind hole coaxial line and axis direction, for level to.One end of screw mandrel passes described horizontal through hole 6-2 and puts among the blind hole 6-3, and the other end of screw mandrel is connected with handwheel 13 by handwheel pin 12.Described release nut 7 is installed in the inboard of the link that has horizontal through hole 6-2, and an end of the corresponding described spring 8 in the outside of this link, the other end of spring 8 is installed described clamping nut 9.And the split washer 10 of spacing usefulness has been installed also on screw mandrel 11.The thread rotary orientation that discharges nut 7 and clamp nut 9 and screw mandrel 11 in this example is left-handed.
The operation principle of present embodiment is: during the cutting plastic tube, make be of moderate size (being advisable) of pipe cutter head opening earlier just in time can put down plastic tube to be cut according to plastic tube caliber size initial adjustment handwheel 13 to be cut, then plastic tube 14 to be cut is placed in the U-shaped opening, screwing handwheel 13 makes screw mandrel 11 move (moving forward) to the head of pipe cutter, thereby clamp nut 9 moves compression spring 8 simultaneously with screw mandrel, the link promotion adjustable shelf 6 that spring pressure passes to adjustable shelf 6 travels forward, this moment, blade was run into plastic tube, along with the increased blade of pressure is cut gradually in the inlet pipe body and (can be controlled penetraction depth by adjusting handle 13), roller 1 props up plastic tube 14 and guarantees that the cut direction of blade can not be offset simultaneously, at this moment rotate whole pipe cutter around plastic tube, make blade rotate a circle, just cut-out that can plastic tube is level and smooth along tube wall.After cutting action is finished, reverse rotation handwheel 13, screw mandrel 11 and release nut 7 move simultaneously backward, and the inboard drive adjustable shelf that release nut 7 props up adjustable shelf 6 links also moves backward, the opening of pipe cutter head is amplified, for next cutting action is got ready.
