Abstract
The utility model discloses a kind of metal insert, metal insert body including hollow cylindrical, the outer peripheral face of the metal insert body has at least one flat horizontal surface axially extended, and the metal insert body is provided with the resistance to plucking step of at least one outer peripheral face for protruding from the metal insert body.The utility model provides a kind of metal insert, increase anti-rotation resistance of the metal insert in working of plastics by setting flat horizontal surface, by setting resistance to plucking step to increase anti-pull-out resistance of the metal insert in working of plastics, reach metal insert anti-rotation and purpose that resistance to plucking goes out.In addition, the structure can direct cold-heading molding, cost reduces by 50%, reduces power consumption, reduces raw material usage, production efficiency improves 10 20 times.
Description
Technical field
The utility model belongs to injection metal insert technical field, more particularly to a kind of metal insert.
Background technology
In the bolt installation place of plastic products, to ensure bonding strength, typically handled in the form of metal insert,
Metal insert is in sleeve-shaped, and inner surface is threaded to be installed for bolt.Structure such as Fig. 1 institutes of traditional injection metal insert
Show, including metal insert 11 and the working of plastics 12 for being wrapped in the outer surface of metal insert 11, the outer surface setting of metal insert 11 are recessed
Groove 13, for increasing anti-pull-out resistance after filling plastic, while pawl (or helical teeth) 14 is set, increased for being embedded in working of plastics 12
Add anti-rotation resistance.Therefore metal insert 11 need to process groove 13 and pawl 14 by the way of turnery processing, be processed into
This height, low production efficiency.
The content of the invention
In view of the defects of above-mentioned prior art is present, the purpose of this utility model is to propose a kind of metal insert.
The purpose of this utility model will be achieved by the following technical programs：
A kind of metal insert, include the metal insert body of hollow cylindrical, the periphery mask of the metal insert body
There is at least one flat horizontal surface axially extended, the metal insert body protrudes from the metal provided with least one
The resistance to plucking step of the outer peripheral face of inserts body.
Further, the inner surface of the metal insert body is female thread structure.
Further, the outer peripheral face of the metal insert body has two symmetrically arranged flat horizontal surfaces.
Further, including two resistance to plucking steps, the resistance to plucking step are located at the metal insert body respectively
Both ends.
Further, the flat horizontal surface and the resistance to plucking step are cold-heading molding.
Prominent effect of the present utility model is：The utility model provides a kind of metal insert, by set flat horizontal surface come
Increase anti-rotation resistance of the metal insert in working of plastics, it is anti-in working of plastics by setting resistance to plucking step to increase metal insert
Pull-out resistance, reaches metal insert anti-rotation and purpose that resistance to plucking goes out.In addition, the structure can direct cold-heading molding, cost reduce
50%, power consumption is reduced, reduces raw material usage, production efficiency improves 10-20 times.
Just accompanying drawing in conjunction with the embodiments below, is described in further detail to specific embodiment of the present utility model, so that this
Utility model technical scheme is more readily understood, grasped.
Brief description of the drawings
Fig. 1 is the structural representation of prior art；
Fig. 2 is the structural representation of the utility model embodiment.
Embodiment
Embodiment
As shown in Fig. 2 a kind of metal insert of the present embodiment, includes the metal insert body 1 of hollow cylindrical, metal is embedding
The inner surface of part body 1 is female thread structure.The outer peripheral face of metal insert body 1 has two and symmetrically arranged axially extended
Flat horizontal surface 2, metal insert body 1 is provided with the resistance to plucking step 3 of two outer peripheral faces for protruding from metal insert body, resistance to plucking platform
Rank 3 is located at the both ends of metal insert body 1 respectively.Wherein, flat horizontal surface 2 and resistance to plucking step 3 are cold-heading molding.
A kind of metal insert is present embodiments provided, by setting flat horizontal surface 2 to increase metal insert in working of plastics
Anti-rotation resistance, by setting resistance to plucking step 3 to increase anti-pull-out resistance of the metal insert in working of plastics, reach metal insert and resist
The purpose that rotation and resistance to plucking go out.In addition, the structure can direct cold-heading molding, cost reduce by 50%, reduce power consumption, reduce raw material
Dosage, production efficiency improve 10-20 times.
The utility model still has numerous embodiments, all technologies formed using equivalents or equivalent transformation
Scheme, all fall within the scope of protection of the utility model.
