Abstract
The utility model relates to the technical field of pipes and pipe fittings, disclosing a novel plastic insert for plastic pipes. The insert is formed from plastic by injection molding, having a via-hole formed at the middle portion and a plurality of ring grooves formed at the outer end. The novel plastic insert has a nut or screw shape, can be prepared from PPS composite material or POM composite material by injection molding, and has the advantages of low material cost and less specific gravity (one fourth to one fifth that of copper). The insert made of plastic obviates the need of machining and milling procedures, and has high production efficiency, low processing cost and low cost by adopting injection molding. Additionally, the plastic insert is connected with a plastic pipe as a whole by injection process, with good bonding characteristics and prevention of loosening and water leakage since the insert and the pipe are made of polymer plastic. Additionally, the insert also has the advantages of simple and convenient structure improvement.
Description
Technical field:
The utility model relates to the used plastic pipe (or claiming plastic fittings) of plastic duct system of building materials field, especially relates to the inserts in the plastic pipe.
Background technique:
Plastic tube and pipe fitting are mainly used in plumbing and quote water pipe system, gas transmission and industrial guard system, heating system and agricultural guard system in building industry, the plastics kind of making plastic tube and pipe fitting comprises HDPE, PP, PPB, PPR, PPH, PVC, ABS, reaches PA or the like.Plastic pipe is also referred to as plastic fittings, and it comprises joint, elbow, threeway and four-way or the like.Inserts in the present plastic pipe basically with metal particularly copper do, the copper inserts have the price height, than great, fabricating cost is high, efficient is low and shortcoming such as processing technology complexity.The utility model inserts adopts plastics to make by Shooting Technique, and alternative metals copper can overcome the above-mentioned shortcoming of copper inserts.
The model utility content:
The purpose of this utility model is the deficiency that exists at prior art and a kind of novel plastic pipe fitting inserts is provided that it has, and fabricating cost is low, proportion is little, production technology is simple and advantage of high production efficiency.
For achieving the above object, the utility model adopts plastics to make the plastics inserts by the mode of molding and forming, and its middle part forms through hole, and the outer end forms a plurality of circular grooves.
Described inserts is nut type, and through hole is the interior threaded hole that runs through insert bodies, and circular groove is positioned on the exterior edge face of insert bodies.
Described inserts is arachnoid, and it is made of the external thread section of front end and the embedding section of rear end, and through hole is the unthreaded hole that runs through the embedding section of the external thread section of inserts front end and rear end, and circular groove is positioned on the exterior edge face that embeds section.
The beneficial effects of the utility model are: it adopts plastics is raw material, (only for copper 1/4th to 1/5th) advantage that has that material price is lower, proportion is little, the plastics inserts does not need through car, machining processes such as mills, the manufacturing efficiency height, and processing cost is low.These plastics inserts and plastic pipe adopt the mode of single injection-molded (insert moulding) to be connected as a single entity.Because plastics inserts and plastic tube are all macromolecule modified material, and be less the relative copper insert of dimensional changes when the Environmental Conditions temperature variation so thermal expansion coefficient is close, the good airproof performance of pipe fitting.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is the utility model embodiment one a plastics insert structure schematic representation;
Accompanying drawing 2 is the schematic representation after plastics inserts in the accompanying drawing 1 and the plastic pipe combination;
Accompanying drawing 3 is the utility model embodiment two a plastics insert structure schematic representation;
Accompanying drawing 4 is the schematic representation after plastics inserts in the accompanying drawing 3 and the plastic pipe combination.
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Shown in the embodiment one: plastics inserts 10 of the present utility model is fixed in the pipe fitting 20, to make things convenient for being connected of pipe fitting 20 and other pipe fittings.Inserts 10 adopts the PPS composite material to make by injection molding process, and its middle part forms through hole 11, as flow channel; The outer end forms a plurality of circular grooves 12.When molding and forming pipe fitting 20, in the mould of the pipe fitting 20 of earlier plastics inserts 10 being packed into, then pipe fitting is injected mould with plastics (PPR, PE, PVC, ABS, PA), the pipe fitting plastics of fusion and plastics inserts 10 engage and solidify.
See shown in accompanying drawing 1 and the accompanying drawing 2: inserts 10 can be nut type, (the inner hole thread bore dia is 10～100mm for the interior threaded hole that runs through inserts 10 main bodys for through hole 11, it comprises specifications such as 20,25,32,40,50,63,75,90), circular groove 12 is positioned on the periphery of inserts 10 main bodys (in the present embodiment, inserts 10 main bodys are cylindric, certainly, insert bodies 10 also can be polygon-shaped).
Shown in the embodiment two: inserts 10 also can be arachnoid, see shown in accompanying drawing 3 and the accompanying drawing 4: (101 external thread diameter also is 10～100mm by the external thread section 101 of front end for it, it comprises specifications such as 20,25,32,40,50,63,75,90) and the embedding section 102 of rear end constitute, through hole 11 is the unthreaded hole of the embedding section 102 of the external thread section 101 that runs through inserts 10 front ends and rear end, and circular groove 12 is positioned on the exterior edge face that embeds section 102.Here it is pointed out that to embed section 102 except can resembling cylindric shown in accompanying drawing 3 and the accompanying drawing 4, also can be polygon-shaped.
