Abstract
The utility model relates to silicon rubber screwed pipe products, which is composed of a silicon rubber pipe without a haff line and a silicon rubber reinforced rib without a haff line. The silicon rubber pipe without a haff line and the silicon rubber reinforced rib without a haff line are respectively prepared. Then, the silicon rubber reinforced rib is coiled and bonded to fix on the surface of the silicon rubber pipe. One end or two ends of a silicon rubber screw pipe are molded with upper contacts according to needs. The inner and the outer surfaces of the silicon rubber screw pipe of the utility model are smooth and clean, have no blind angles, and are not provided with the haff lines which the surface of silicon rubber pipe produced by a mold inheres. Thus, the utility model is especially suitable for medical care.
Description
The utility model relates to a kind of rubber helical tube, and specifically the utility model is a kind of improved silicon rubber helical tube.
Existing silicon rubber helical tube can be included in the pipe one or both ends with silicone rubber reinforcing rib and silicone rubber tube compression molding, therefore the total surface of silicone rubber thread tube is to have the Hough line that the mould connecting part forms, its inner surface of tube is bright and clean inadequately, usually have the dead angle, in medical treatment, use, increase the possibility of staiing microbiological contamination, the pipe thickness of silicone rubber thread tube is restricted simultaneously, more than 1 millimeter, has influenced the improvement of the softness of pipe at least.
The purpose of this utility model provides a kind of improved silicone rubber thread tube, adopt unvulcanized silicone rubber, silicone rubber spiral shell strength bar and silicone rubber tube by preparation respectively, after the sulfuration typing, again silicone rubber reinforcing rib is wrapped in silicone rubber tube surface, and adopt Bond that the two bonding is fixing, in the mold pressing upper connection of the one or both ends of silicone rubber thread tube, be the silicon rubber helical tube of not being with the Hough line as required.
The utility model has the advantages that significantly, evenly bright and clean, the no dead angle of the inner and outer surface of silicone rubber thread tube at first, and do not have the Hough line that forms by the mould connecting part, and therefore can reduce the possibility of staiing microbiological contamination, meet medical upward usage requirement.The pipe thickness of silicone rubber thread tube can reach below 1 millimeter simultaneously, to satisfy the further requirement to the ductility of silicon rubber helical tube.
The utility model does not need the mould of special global design, can form difformity, the silicone rubber thread tube of different tube diameters and different strength bar sectional shape, different strength bar density degree.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Accompanying drawing 1 is for having the silicone rubber thread tube front view of part section.
Accompanying drawing 2 is the erection drawing of the silicone rubber thread tube that has two pipe joints.
Be two embodiments of the present utility model below:
Embodiment 1:
As shown in Figure 1, the utility model silicone rubber thread tube (3) is by unvulcanized silicone rubber, by independent preparation not with the silicone rubber reinforcing rib (1) of Hough line sulfuration back uniform winding preparation separately not with the silicone rubber tube after the sulfuration of Hough line (2) surface on, adopt silicone rubber Bond bonding fixing.
Embodiment 2:
As shown in Figure 2, the utility model silicone rubber thread tube (3) is by unvulcanized silicone rubber, by independent preparation not with the silicone rubber reinforcing rib (1) of Hough line sulfuration back uniform winding preparation separately not with the silicone rubber tube after the sulfuration of Hough line (2) surface on, adopt silicone rubber Bond bonding fixing, pipe end mold pressing upper connection (4,4 '), be silicone rubber thread tube (3) goods of being with pipe joint.
As the conversion of present embodiment, silicone rubber tube (2) can be for the pipe or the solid pipe of the circular or non-circular axial hollow of Hough line; With silicone rubber tube (2) coupling can not be U type, semicircle, trapezoidal or square etc. with the cross section of the silicone rubber reinforcing rib (1) of Hough line, and it can be the screw thread of evenly distributed or inhomogeneous arrangement on silicone rubber tube (2) surface.The wall thickness of silicone rubber tube (2) can be less than 1 millimeter, and the Bond that is adopted can be one-component silicone rubber Bond or two-component silicone rubber Bond, and what preferentially adopt is one-component room curing silicon rubber Bond.
