Detailed Description

As shown in fig. 1 to 3, the present embodiment provides a lamp instrument housing structure, which includes a housing 1 and an expansion cap 2. Wherein, be equipped with on casing 1 with hold bleeder vent 12 of chamber 111 intercommunication, its characterized in that, lamps and lanterns instrument housing structure is equipped with pressure regulating chamber 23 including inflation cap 2 on the inflation cap 2, and the material of inflation cap 2 can block water and gentleness and pass through, inflation cap 2 and casing 1 sealing connection, and pressure regulating chamber 23 and bleeder vent 12 are through connecting pipe (13) intercommunication.

The lamp instrument shell structure that this embodiment provided, when the gas in the lamp instrument holds chamber 11 and receives the temperature influence change, inflation cap 2 carries out corresponding flexible deformation, the inside atmospheric pressure of regulation lamp body that can be timely. In addition, the expansion cap 2 forms a closed space with the inside of the lamp instrument, and can effectively isolate impurities such as external water and gas from entering the inside of the lamp instrument, so that the phenomenon that the lamp instrument is corroded and even damaged due to corrosion caused by the impurities such as water and gas in the inside of the lamp instrument is prevented.

Optionally, the expansion cap 2 comprises a connecting portion 22 and a telescopic portion 21, the connecting portion 22 and the telescopic portion 21 enclosing a pressure regulating chamber 23, the connecting portion 22 being adapted to be sealingly connected to the housing 1. In this embodiment, the expansion cap 2 is made of a rubber material that is impermeable to air, water and corrosion.

Alternatively, the expansion part 21 is of a corrugated structure, the difference between the inner diameter and the outer diameter of the corrugated structure of the expansion part 21 is a certain value, and since the expansion cap 2 is provided with the expansion part 21, when the heated volume of the gas in the accommodating cavity 111 becomes large, the corrugated structure of the expansion part 21 is expanded, and when the cooled volume of the gas in the accommodating cavity 111 becomes small, the corrugated structure of the expansion part 21 is contracted. And the volume of the pressure regulating cavity 23 changes along with the extension of the corrugated structure, so that the pressure regulation can be realized without elastic deformation of the expansion cap 2 in a certain range, and the pressure regulating response is quick.
