Description
Technical field
The utility model relates to distribution box technical field, relates in particular to a kind of distribution box line structure.
Background technology
Distribution box line is to connect electric energy meter, earth leakage protective device, the section of opening user low-voltage load air switch dressPut user's electrical equipment rubber-covered aluminum steel or rubber control cables line, distribution box bottom is provided with for lineLine hole, because construction causes cable bad or uses for a long time cable aging, the online hole of cable withEasily leaking electricity in the position of distribution box contact, makes distribution box easily occur electric shock accidents, poor stability.
Summary of the invention
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of distribution box to enterOutlet structure, reasonable in design, improves its security by protection tube is installed in distribution box, avoids tactileThe generation of electrification.
The utility model solves the technical scheme that its technical problem adopts:
A kind of distribution box line structure, comprises the casing that is provided with chamber door, and the bottom surface of casing is provided with some linesHole, is characterized in that: also comprised be positioned at casing and with line hole one to one protection tube and for installThe sleeve pipe base of protection tube, described sleeve pipe base distributes along corresponding line bore edges, described protection tubeBottom coordinates with sleeve pipe base to peg graft to be fixed, and inner side, protection tube top is provided with the sealing gasket of coupling, protectionOn the inwall of pipe, be also provided with some equally distributed support fins.
Described support fin vertical direction distributes or helicoidal structure distributes.
Described support fin bottom flushes setting with protection tube bottom end opening, supports fin top and sealing gasketOffset.
Described support fin is elastic caoutchouc material.
Described sealing gasket is elastic caoutchouc material or elastic sponge material.
Described line hole adopts knock down hole structure.
In sum, the utlity model has following beneficial effect: reasonable in design, by distribution boxInterior installation protection tube improves its security, avoids the generation of electric shock accidents, ensures that distribution box uses safety.

Detailed description of the invention
By particular specific embodiment, embodiment of the present utility model, person skilled in the art scholar are described belowCan understand easily other advantages of the present utility model and effect by the disclosed content of this description.
With reference to the accompanying drawings shown in 1,2,3,4: the utility model provides a kind of distribution box line structure, bagDraw together the casing 1 that is provided with chamber door 2, the bottom surface of casing 1 is provided with eight line holes 3, and line hole 3 is according to cable specificationBe divided into multiple diameter size.
Wherein this structure also comprised be positioned at casing 1 and with line hole 3 one to one protection tube 5 and forThe sleeve pipe base 4 of protection tube 5 is installed; Described sleeve pipe base 4 is along corresponding line hole 3 edge distribution,Its diameter is slightly larger than line hole 3 sizes corresponding with it, makes its inner installation and the same diameter in line hole 3Protection tube 5; Described protection tube 5 bottoms and sleeve pipe base 4 are pegged graft and are fixed, protection tube 5 topsInner side is provided with the sealing gasket 7 of coupling, and sealing gasket 7 is elastic sponge material, on the inwall of protection tube 5, also establishesHave some equally distributed support fins 6, supporting fin 6 is elastic caoutchouc material, supports fin 6 entiretyVertical direction distributes, and supports fin 6 bottoms and flushes setting with protection tube 5 bottom end openings, supports fin 6 and pushes upEnd offsets with sealing gasket 7.
In the time that cable is worn line-entering hole 3, penetrate into protection tube 5, in cable size and protection tube 5 simultaneouslyFootpath Incomplete matching, tilted or be out of shape cable is propped up by the support fin 6 in protection tube 5Support is fixing, and the sealing gasket 7 that is simultaneously positioned at protection tube 5 top end openings is wrapped in cable meter by strainFace, plays sealing function, for the equipment operating environment in casing 1 has improved guarantee.
The foregoing is only preferential embodiment of the present utility model, as long as realize this reality with basic identical meansBy novel object technical scheme, within all belonging to protection domain of the present utility model.
