A kind of rotational moulding product inner screw thread insert, belongs to and is threadedly engaged Element Technology field.The rotational moulding product inner screw thread insert, including inserts ontology and anti-rotation stub；Internal thread structure is arranged in the inserts inner body wall, is arranged circumferentially one group of stub pilot hole in inserts body outer wall；The anti-rotation stub is mounted in stub pilot hole, and outboard end is stretched out from stub pilot hole, and inner end is located inside stub pilot hole, generates interference to avoid with inserts ontology internal thread structure.The utility model solves the problems, such as that existing pre-buried threaded insert is rotated with when by external larger torsion, loosened, and has achieved the purpose that improve rotational moulding product quality.
Description
Technical field
The utility model relates to a kind of rotational moulding product inner screw thread inserts, belong to and are threadedly engaged Element Technology field.
Background technique
Rotational moulding is a kind of processing method of plastic products, and molding die is low in cost, can be within the scope of cost-effectively
Component of different sizes is easily produced, therefore is widely used in middle empty class, the double-deck class and complicated plastics and produces
The forming process of product.
It is docked since many rotomoulded articles require to be connected through a screw thread mode to be sealed with component, it is therefore desirable to
In rotational moulding product designated position, screw thread is set.At present there are mainly two types of the thread forming modes of rotational moulding product, one is pass through rolling
Modeling technique utilizes the screw thread straight forming above mold；Another kind is as obtained from pre-buried threaded insert.Wherein based on rolling
The screw strength for moulding technique straight forming is low, easy to wear, is used primarily for that frequency is low, the low environment of seal request；And pass through
Pre-buried threaded insert mode obtains metal threaded, not only overcomes drawbacks described above completely, but also this metal threaded general logical
Rectangular or circular metal shape extrusion is crossed to form, it is easy to process quick, but existing pre-buried threaded insert is engaged with plastic material
Position is generally continuous curved surface, and frictional resistance is small, and when by external biggish torsion, threaded insert can rotate with, is loose
It is dynamic, so that the plastics being wrapped in above it are detached from it, to cause rotomoulded articles partial function defect.
Utility model content
The utility model provides a kind of rotational moulding product inner screw thread insert, it is intended to solve existing pre-buried threaded insert by
The problem of rotating with, loosens when to external larger torsion, achievees the purpose that raising rotational moulding product quality.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of rotational moulding product inner screw thread insert, including inserts ontology and anti-rotation stub；The inserts inner body wall is set
Internal thread structure is set, is arranged circumferentially one group of stub pilot hole in inserts body outer wall；The anti-rotation stub is mounted on short
In stick pilot hole, outboard end is stretched out from stub pilot hole, and inner end is located inside stub pilot hole, to avoid with inserts sheet
Internal helicitic texture generates interference.
Above-mentioned rotational moulding product inner screw thread insert, the anti-rotation stub are cylindrical structure, are arranged on its outer surface
External screw thread；Stub pilot hole is threaded hole on the inserts ontology, and anti-rotation stub is connected through a screw thread structure and inserts ontology
Assembly.
Annular recess is arranged on the inserts body outer wall in above-mentioned rotational moulding product inner screw thread insert, and the anti-rotation is short
Stick intersects vertically with annular recess.
Above-mentioned rotational moulding product inner screw thread insert, the inserts body outer surface are cylindrical surface, the anti-rotation stub number
Amount is four, is arranged circumferentially along inserts body outer surface.
The utility model is a kind of rotational moulding product inner screw thread insert, it is filled by opening up stub on this body sidewall of inserts
Distribution, and installation has externally threaded anti-rotation stub in stub pilot hole, anti-rotation can be arranged according to the requirement of different torsion
The quantity and contour structures of dynamic stub, so that threaded insert be made to be provided with very strong anti-rotation kinetic force；The utility model is also embedding
Annular recess is set on part body outer wall, the bonding area and friction for increasing threaded insert and plastic material in rotational moulding product hinder
Power further enhances the anti-rotation kinetic force of threaded insert；Rotational moulding product inner screw thread insert described in the utility model, direct vehicle
Bed processing, forms, therefore the threaded insert has many advantages, such as less investment without die casting, easy to process, is suitable for small
In batches, the inserts of multi items pattern, the characteristics of meeting rotational moulding demand, in addition the inner screw thread insert uses metal material, has strong
The advantages that spending height, high temperature resistant, good rotproofness.It can be seen that the utility model solve existing pre-buried threaded insert by
The problem of rotating with, loosen when external larger torsion has achieved the purpose that improve rotational moulding product quality.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the main view of the utility model；
Fig. 3 is the top view of the utility model.
Each list of reference numerals in figure are as follows: 1, inserts ontology, 1-1, internal thread structure, 1-2, annular recess, 2, anti-rotation stub,
2-1, external screw thread.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, Fig. 3, the utility model is a kind of rotational moulding product inner screw thread insert, it includes inserts ontology 1
With anti-rotation stub 2；1 outer surface of inserts ontology is cylindrical surface, and internal thread structure 1-1 is arranged in inner wall, in inserts ontology 1
Outer wall is arranged circumferentially four threaded holes for stub assembly；The anti-rotation stub 2 is cylindrical structure, in its appearance
External screw thread 2-1 is set on face, after anti-rotation stub 2 is connected through a screw thread the threaded hole assembly of structure and inserts ontology 1, outside
End is stretched out from stub pilot hole, and inner end is located inside stub pilot hole, to avoid the internal thread structure 1- with inserts ontology 1
1 generates interference.
Referring to Fig. 1, Fig. 2, rotational moulding product inner screw thread insert described in the utility model is set on 1 outer wall of inserts ontology
Annular recess 1-2 is set, the anti-rotation stub 2 intersects vertically with annular recess 1-2.
Referring to Fig. 1, Fig. 2, Fig. 3, rotational moulding product inner screw thread insert described in the utility model, by inserts ontology 1
Stub pilot hole is opened up on side wall, and installation has externally threaded anti-rotation stub 2 in stub pilot hole, it can be according to different torsions
The quantity and contour structures of the requirement setting anti-rotation stub 2 of power, so that threaded insert be made to be provided with very strong anti-rotation kinetic force；
Annular recess 1-2 is arranged in the utility model also on 1 outer wall of inserts ontology, increases threaded insert and plastics material in rotational moulding product
The bonding area and frictional resistance of matter further enhance the anti-rotation kinetic force of threaded insert.
