Abstract
The invention discloses an explosion-proof member, comprising a metal shell I and a metal shell II, wherein an explosion-proof joint surface is a joint surface formed by the metal shell I and the metal shell II. The explosion-proof member is characterized in that a plastic member is embedded at the side of the metal shell II close to the explosion-proof cavity body. The explosion-proof member can be applicable to explosion-proof appliances and explosion-proof lamps; due to adoption of the structure, the weight of the explosion-proof appliance can be reduced, and the explosion-proof member can be applicable to lamps made of various materials, and the explosion-proof member has a good explosion-proof effect and light distribution; and in addition, the explosion-proof member disclosed by the invention has the advantages of simple structure and low manufacturing cost and the like, thus having wide application prospect.
Description
Technical field
The present invention relates to a kind of explosion-proof member, specifically, relate to a kind of plastics embedded metal formula explosion-proof member, belong to explosion-proof device technical field.
Background technology
As a rule, explosion-proof member is divided into by type flame-proof type, INCREASEDSAFETY, essential safe type, positive pressure type, oil-filled type, fills sand mold, Non-spark, special type.For flame-proof type member, for making explosive-proof grade reach II C T6 level, explosion-resistant enclosure housing normally adopts composite structured that metal and die cast metal form, and described metal is generally Birmasil, cast iron or cast steel.Although the explosion-proof composition surface of this structure is the optimal selection that realizes good explosion-proof effect, adopt the explosion-proof electric apparatus of this explosion separation structure to have weight heaviness, defect that cost is high; In addition, if explosion-proof lamp adopts this structure, for the lamp housing of some material, as glass, can there is luminous intensity distribution to pay no attention to think of the problem such as explosion-proof effect is bad.
Summary of the invention
In view of the foregoing defects the prior art has and problem, the object of this invention is to provide a kind of applied widely, flame proof is effective, cost of manufacture is low novel explosion-proof member, to meet the application requirements of explosion-proof electric apparatus and explosion-proof lamp.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of explosion-proof member, comprises metal shell I and metal shell II, and explosion-proof composition surface is the composition surface being formed by metal shell I and metal shell II, it is characterized in that: be inlaid with plastic member at metal shell II near explosion-proof chamber side.
As further preferred version, described plastic member is embedded on the sidewall of metal shell II.
As preferred version further, the composition surface indentation of described plastic member and metal shell II or wavy.
As preferred version further, described plastic member is engaged and is integrated with metal shell II by quadric injection mould or mould pressing technology.
As further preferred version, the material of described plastic member is thermoset plastics or thermoplastics.
As preferred version further, described thermoset plastics is selected from SMC or DMC.
As preferred version further, described thermoplastics is selected from Merlon (PC), polypropylene (PP), acrylonitrile-butadiene-styrene (ABS) (ABS) or polyhexamethylene adipamide (PA66).
As further preferred version, described metal shell I and the material of metal shell II are cast iron, cast steel or Birmasil.
As further preferred version, between described metal shell I and metal shell II by bolt or be threaded fixing.
Compared with prior art, explosion-proof member of the present invention, applicable in explosion-proof electric apparatus and explosion-proof lamp, adopts structure of the present invention, not only can alleviate the weight of explosion-proof electric apparatus, applicable to the light fixture of various material, and has good explosion-proof effect and luminous intensity distribution; In addition, explosion-proof member of the present invention has the advantages such as simple in structure, low cost of manufacture; Therefore have broad application prospects.
Brief description of the drawings
Fig. 1 is the cross-sectional view of explosion-proof member provided by the invention.
In figure: 1, metal shell I; 2, metal shell II; 3, explosion-proof composition surface; 4, plastic member; 5, bolt.
Embodiment
Below in conjunction with accompanying drawing to the present invention do further in detail, intactly explanation.
As shown in Figure 1, explosion-proof member provided by the invention comprises: metal shell I 1 and metal shell II 2, and explosion-proof composition surface 3 is the composition surfaces that formed by metal shell I 1 and metal shell II 2, it is characterized in that: be inlaid with plastic member 4 at metal shell II 2 near explosion-proof chamber side.
As further preferred version, described plastic member 4 is embedded on the sidewall of metal shell II 2.
As preferred version further, described plastic member 4 and the composition surface indentation of metal shell II 2, also can be wavy other shape such as grade.
As preferred version further, described plastic member 4 is engaged and is integrated with metal shell II 2 by quadric injection mould or mould pressing technology.
As further preferred version, the material of described plastic member 4 is thermoset plastics or thermoplastics; Described thermoset plastics is preferably from SMC or DMC; The preferred self-polycarbonate of described thermoplastics (PC), polypropylene (PP), acrylonitrile-butadiene-styrene (ABS) (ABS) or polyhexamethylene adipamide (PA66).
As further preferred version, described metal shell I 1 and the material of metal shell II 2 are cast iron, cast steel or Birmasil.
As further preferred version, between described metal shell I 1 and metal shell II 2, be connected and fixed by bolt 5, also can be threaded connection fixing.
In sum, explosion-proof member of the present invention, applicable in explosion-proof electric apparatus and explosion-proof lamp, adopts structure of the present invention, not only can alleviate the weight of explosion-proof electric apparatus, applicable to the light fixture of various material, and has good explosion-proof effect and luminous intensity distribution; In addition, explosion-proof member of the present invention has the advantages such as simple in structure, low cost of manufacture; Therefore have broad application prospects.
Finally be necessary to be pointed out that at this: above content is only for being described in further detail technical scheme of the present invention; can not be interpreted as limiting the scope of the invention, some nonessential improvement that those skilled in the art's foregoing according to the present invention is made and adjustment all belong to protection scope of the present invention.
