Easily due to electric wire is hitched cover stress is caused to be burst apart in vertical direction, so it is bad to have customer response properties of product.
Material is Lauxite used by existing market, which has good salt water resistance, can also meet safety
Minimum requirement, but actual in use, plug can often be broken so that service life shortens significantly, main former
Because the mechanical strength for being exactly Lauxite is inadequate；Increase its toughness according to the mode of addition wood fibre resin, then cost is very
Height is approximately original 2 times；If adding, wood fibre resin is excessive, and material is very poor in membrane cavity internal mobility, and shaping rear cover body is not noted
It is full more, the shaping fraction defective of upper and lower covers is caused to remain high always.
Therefore, it is necessary to a kind of gas alarm power-line plug of 180 ° of new rotary-connecting double-layer structures is provided to solve
The above problem.
【Utility model content】
The main purpose of the utility model is that provide a kind of gas alarm power cord of 180 ° of rotary-connecting double-layer structures
Plug, salt water resistance is strong, high mechanical strength, and can effectively avoid causing cover due to electric wire is hitched in plug vertical direction
Stress is burst apart.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of gas report of 180 ° of rotary-connecting double-layer structures
Alert device power-line plug, including the first shell, second housing and metal insert, by first shell and described second outside
Shell surrounds in the first cavity formed and is provided with the first inner casing and the second inner casing, and the upper surface of first inner casing is provided with switching
First jack, the first jack plug orientation is identical with the plug orientation of the metal insert, on first shell
The first opening for exposing first jack is provided with, being provided with the second of the exposing metal insert on the second housing opens
Mouthful.
Further, first inner casing is the housing being molded using Lauxite with second inner casing, described
Metal insert and connecting wire, which are arranged at, to be surrounded by first inner casing and second inner casing in the second cavity formed.
Further, housing of first shell with the second housing to be molded using ABS plastic.
Further, the first inner casing upper surface is provided with the first protrusion stretched into first opening, and described the
One jack is located in the described first raised scope.
Further, the upper surface of first protrusion is substantially flush with first upper surface of outer cover.
Further, the lower surface of second inner casing is provided with the second protrusion stretched into second opening and supplies
The second jack that the metal insert passes through, second jack are located in the described second raised scope.
Further, the lower surface of second protrusion and the lower surface of the second housing are substantially flush.
Further, be provided on first inner casing and the second inner casing inner surface it is several to the metal insert and
Conducting wire carries out the /V catch of /V.
Compared with prior art, a kind of gas alarm power-line plug of 180 ° of rotary-connecting double-layer structures of the utility model
Advantageous effect be：Salt water resistance is strong, high mechanical strength, and can effectively avoid in plug vertical direction because electric wire is hitched
And cover stress is caused to be burst apart.

【Specific embodiment】
Embodiment：
Fig. 1-Fig. 2 is refer to, the present embodiment is the gas alarm power-line plug of 180 ° of rotary-connecting double-layer structures, is wrapped
The first shell 1, second housing 2 and metal insert 3 are included, is surrounded by the first shell 1 with second housing 2 in the first cavity formed
The first inner casing 4 and the second inner casing 5 are provided with, the upper surface of the first inner casing 4 is provided with the first jack 41 of switching, the first jack
41 plug orientation are identical with the plug orientation of metal insert 3, and the first opening for exposing the first jack 41 is provided on the first shell 1
11, the second opening 21 for exposing metal insert 3 is provided on second housing 2.
Since the plug of the present embodiment is mainly used for the kitchen place for having imflammable gas to burn, it is required relatively strong
Salt tolerance and corrosion resistance, currently on the market mostly using Lauxite, but the material price is very expensive, in order to ensure it is full
Cost can be reduced under the premise of sufficient safety, the first inner casing 4 and the second inner casing 5 in the present embodiment are using having compared with strong corrosion resistant
The urea-formaldehyde materials of performance are molded, and metal insert 3 and connecting wire are arranged at by the first inner casing 4 and second
