Embodiment Construction

[0017] The present invention will be described in further detail and completely below in conjunction with the accompanying drawings.

[0018] Such as figure 1 As shown, the flameproof component provided by the present invention includes: a metal casing I 1 and a metal casing II 2, and the explosion-proof joint surface 3 is a joint surface formed by the metal casing I 1 and the metal casing II 2, and is characterized in that: in the metal casing II 2 is inlaid with a plastic component 4 near the side of the explosion-proof cavity.

[0019] As a further preferred solution, the plastic component 4 is embedded on the side wall of the metal casing II 2 .

[0020] As a further preferred solution, the joint surface of the plastic member 4 and the metal casing II 2 is in a zigzag shape, and may also be in other shapes such as a wave shape.

[0021] As a further preferred solution, the plastic component 4 is integrated with the metal casing II 2 through secondary injection molding or...

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 [0001] The invention relates to a flame-proof component, in particular to a plastic-embedded metal type flame-proof component, which belongs to the technical field of explosion-proof devices. Background technique [0002] Generally speaking, explosion-proof components are divided into flameproof type, increased safety type, intrinsically safe type, positive pressure type, oil-filled type, sand-filled type, non-spark type, and special type according to type. For explosion-proof components, in order to make the explosion-proof grade reach II C T6, the explosion-proof shell is usually a composite structure made of metal and metal die-casting, and the metal is generally cast aluminum alloy, cast iron or cast steel. Although the explosion-proof joint surface of this structure is the best choice to achieve a good explosion-proof effect, the explosion-proof electrical appliances using this explosion-proof structure have the defects of heavy weight and high cost; in ...
