Abstract
The utility model discloses a rubber plastic pipe cutter, composed of two hinged plier bodies with handles. Cutting blades are fixed on the jaw of one pincers body. The jaw of the other pincers body is provided with two sets of rotary vehicle wheel assemblies with clamping grooves. The two sets of vehicle wheel assemblies and the apex of the cutting blades form the three points holding the pipe. The pipe rotates as the cutting blades are feeding until the pipe is cut off. The utility model has the advantage of simple structure, artful design, convenient operation, good effect and high efficiency. The utility model is an indispensable novel tool replacing galvanized iron pipes in installation and maintenance of plastic pipes.
Description
The utility model relates to the cutting tool of rubber and plastic tubing.
Rubber and plastic tubing is because of the characteristic of its material, must realize cutting stock by special-purpose cutting clamp, the arriving that puts into the melting pot along with water supply pipe, non-toxic plastic tubing is about to replace when easily getting rusty the galvanized iron conduit that is detrimental to health, in the installation and maintenance engineering of pipeline, bound simple in structure, the pipe cutting clamp of moulding easy to use, it is 87214402 multi-functional pipe wrench that one application number is arranged in the prior art, by fixed caliper, moving caliper, handle, eccentric handle, ratchet and two dead axles constitute, drive caliper by turning handle during use and slide, realize its clamping and continue turning the purpose of pipe, this kind pipe wrench is complicated, use trouble, cutting efficiency is low.
The purpose of this utility model is to overcome the defective of prior art and provides a kind of simple in structure, rubber and plastic tubing cutting clamp easy to use, the cutting efficiency of raising cutting clamp.
The utility model is by following scheme implementation: comprise two band handle calipers, be hinged and connected with bearing pin that be fixed with cutting blade on the jaw of a caliper, the jaw of another caliper is provided with two groups of rotating roll wheel assemblies with draw-in groove.
The utility model utilizes rotating roll wheel assembly, rotates the tubing that is cut and promptly can cut off tubing fast in the cutting blade feed, and the design is simple in structure, design ingenious, use easily, good cutting effect and efficient height are that indispensable instrument is installed and keeped in repair to plastic conduit.
Description of drawings.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the right side view of Fig. 1.
Fig. 3 is the A-A cutaway view of Fig. 1.
Below in conjunction with above-mentioned accompanying drawing embodiment of the present utility model is elaborated again.
As Figure 1-3, rubber and plastic tubing cutting clamp comprises the caliper (1) of two band handles, plugs the back and is hinged and connected into the general tool pincers with bearing pin (3), and the pincers handle cross section of two calipers is " U " type, and opening is relative, and cladding has plastics system sheath (6) on the pincers handle of " U " type.The jaw of a caliper has narrow groove, and cutting blade (2) is fixed in the narrow groove, cutting blade expose the periphery and drift angle be the cutting cutting edge.The jaw of another caliper has the groove of broad, two groups of rotating roll wheel assemblies with draw-in groove (8) are located in the groove of broad, the pin (10) that comprises roller (7), matched in clearance is connected on the jaw with packing ring (9) riveted mutually, described roller (7) can be to have the disjunctor duplicate gear of draw-in groove or two simply connected rollers of being separated by by spacer ring, the drift angle of two groups of roll wheel assemblies and cutting blade constitutes 3 points of clamping rubber and plastic tubing, and cutting blade just in time is fastened in the draw-in groove of roll wheel assembly when jaw is closed.
Cutting blade directly bumps against and the damage cutting edge with the roll wheel assembly draw-in groove when preventing that jaw is closed, on the pincers handle of caliper, be provided with position-limit mechanism, this mechanism comprises that an end is welded on a reed (4) and a close-fitting on the pincers handle and clamps the combination of the spacer pin (5) on handle at another, adopt the purpose of reed to be cushioning effect, make the closed spacing usefulness of two jaws.
When needing cutting rubber and plastic tubing, open the jaw of caliper, rubber and plastic tubing is stretched among 3 that are made up of two groups of roll wheel assemblies and cutting blade summit, rotation rubber and plastic tubing in the cutting blade feed, because the synchronous rotation of two groups of roll wheel assemblies, help rubber and plastic tubing and cut off fast in rotation, the tangent plane that cuts off is smooth and smooth.
Claims (5)
1, a kind of rubber and plastic tubing cutting clamp, comprise two band handle calipers (1), be hinged and connected with bearing pin (3), it is characterized in that being fixed with cutting blade (2) on the jaw of a caliper, the jaw of another caliper is provided with two groups of rotating roll wheel assemblies with draw-in groove (8).
2, rubber and plastic tubing cutting clamp as claimed in claim 1, the pincers handle that it is characterized in that caliper (1) is provided with cutting blade and the direct position-limit mechanism that bumps against of roll wheel assembly draw-in groove when preventing the jaw closure, and this mechanism comprises that being located at one clamps the reed (4) on the handle and be located at the combination that another clamps the spacer pin (5) on handle.
3, rubber and plastic tubing cutting clamp as claimed in claim 1 or 2, it is characterized in that described roll wheel assembly comprises the roller with draw-in groove (8) (7) on the jaw that is located at a caliper (1), this roller is linked to each other with packing ring (9) riveted by the pin (10) of matched in clearance.
4, rubber and plastic tubing cutting clamp as claimed in claim 3 is characterized in that described roller (7) is the duplex roller of disjunctor or two simply connected rollers of being separated by by spacer ring.
5, rubber and plastic tubing cutting clamp as claimed in claim 1 is characterized in that described pincers handle is provided with sheath (6).
