Abstract
The utility model discloses a waterproof air-permeable plug of a guardrail tube. The waterproof permeable plug comprises a plug body, wherein the side wall of the plug body is provided with a wiring hole and a ventilation hole and the ventilation hole is arranged above the wiring hole. According to the utility model, the ventilation hole arranged on the plug plays a breathing and ventilating role and can balance internal and external pressures, thereby effectively balancing the internal and external temperature and air pressure of the guardrail tube.
Description
Technical field
The utility model relates to a kind of plug, relates to a kind of plug that is used for light fixture guardrail pipe two ends in particular.
Background technology
Light fixture (for example street lamp) all is to be placed in the guardrail pipe when installing, and two ends of guardrail pipe are at the plug of installing the whole casing sealing; In the time of light fixture work, the meeting evolution of heat, the inner air of guardrail pipe receives influence of temperature change; And then shrink, expand, cause the pressure in the guardrail pipe to increase, make the guardrail pipe under the effect of external and internal pressure difference, be squeezed; Go down for a long time to make the seal failure of guardrail pipe and plug, outside water can get in the guardrail pipe.
The utility model content:
The utility model be weak point according to prior art, a kind of guardrail pipe waterproof and breathable plug is provided.
The technological solution of the utility model is following:
Guardrail pipe waterproof and breathable plug comprises the plug body, and the sidewall of said plug body is provided with a cable hole, a passage, and described passage is positioned at the top of said cable hole.
Described guardrail pipe waterproof and breathable plug has one and the corresponding boss in said passage position on the outside face of described plug body, described passage stretches out and runs through described boss.
Described guardrail pipe waterproof and breathable plug, described passage be positioned at said cable hole directly over.
Described guardrail pipe waterproof and breathable plug, the diameter of described passage is less than the cable hole diameter.
Described guardrail pipe waterproof and breathable plug, the outside face of said plug body has a baffle plate that said cable hole, passage are covered up.
Described guardrail pipe waterproof and breathable plug, described baffle plate have an extension board that extends to said sidewall.
Described guardrail pipe waterproof and breathable plug, described boss is a cylinder.
The beneficial effect of the utility model is: this novel plug is provided with passage; Can play the effect of ventilating, balance external and internal pressure; Active balance guardrail pipe internal and external temperature, air pressure; And a baffle plate that cable hole, passage are covered up is arranged in addition, can play the excellent waterproof effect like this.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
Embodiment sees accompanying drawing 1,2; Guardrail pipe waterproof and breathable plug comprises plug body 1, and the sidewall 101 of said plug body 1 is provided with a cable hole 101a, a passage 101b, and described passage 101b is positioned at the top of said cable hole 101a.
One and the corresponding boss 101c in said passage 101b position are arranged on sidewall 101 lateral surfaces of described plug body 1, and described passage 101b stretches out and runs through described boss 101c.
Described passage 101b be positioned at said cable hole 101a directly over.
The diameter of described passage 101b is less than cable hole 101a diameter.
Described baffle plate 102 has an extension board 102a who extends to said sidewall 101.
