Embodiment 1

[0028] A tubular enclosed lamp, comprising a transparent tubular shell 1, a base plate 2 installed in the tubular shell and a lamp tube 3 mounted on the base plate, the two ends of the tubular shell are provided with sealing end caps 11, and inside the sealing end caps A sealing ring 12 is provided, and a thinning ring is also provided on the bottom surface of the sealing end cap. Both ends of the strip-shaped substrate 2 are provided with end holes 21, and the back side of the end hole 2 is provided with side wings 211 folded by it. The socket socket 4 is inserted into the port hole 21, and the socket socket 4 includes a seat cover 41, a fixing part arranged in the seat cover and a contact piece electrically connected with the contact on the lamp tube. The seat cover 41 and the fixing part are provided with a lamp tube installation hole corresponding to the side facing the lamp tube 3 , and the bottom of the seat cover 41 is provided with a base 411 . There are protrusions o...

Embodiment 2

[0031] The difference from Embodiment 1 is that Embodiment 2 has side slots on the base 411 on both sides opposite to the side wings 211 . Groove fixed socket 4.

[0032] This embodiment can ensure the full sealing of the lamp, and it is safer to use. The structure of the socket is simple, and the installation with the lamp tube is stable and firm. The socket is fixed by the base and the side of the end hole, which is more secure. Moreover, the installation and disassembly are also convenient, which can overcome the defects of poor contact of the lamp tube and troublesome maintenance.

Abstract

The invention relates to the field of lamps and lanterns, particularly to a tubular sealed lamp which comprises a transparent tubular outer casing, a base plate mounted in the tubular outer casing, and a lighting tube mounted on the base plate, wherein end holes are formed in the two ends of the base plate; an insertion seat is mounted in each end hole; the lighting tube is fixed on the base plate through the insertion seats; each insertion seat comprises a seat sleeve, a fixing piece arranged in the seat sleeve and a wafer electrically connected with each contact of the lighting tube; lighting tube mounting holes are formed in one sides, facing to the lighting tube, of each seat sleeve and each fixing piece correspondingly and respectively; a base is arranged at the bottom end of each seat sleeve; side wings are arranged on the two sides of the reverse surface of each end hole; each insertion seat and each end hole are fixed through each base and each side wing. Therefore, the structure is simple, the sealing effect is excellent, and the lighting tube and the insertion seats are mounted firmly.

Description

technical field [0001] The invention relates to the field of lamps, in particular to a tubular sealed lamp. Background technique [0002] Lighting lamps are used more and more widely in production, storage, and rescue, and there are more and more varieties. Due to explosive gas, dust or water vapor in these places, it is easy to cause corrosion of lamps, and the service life of lamps is greatly shortened. In severe cases, it will cause Explosion, causing heavy losses and even casualties. For this reason, many merchants have invented closed explosion-proof lamps to avoid direct contact of explosive gas, dust or water vapor with the lamp tube and the driving device, which can effectively reduce the explosion of the lamps and improve the service life of the lamps. However, due to these closed explosion-proof The lamp and the lamp tube are arranged in the housing through the socket. Once the lamp tube is in poor contact with the socket or slips off from the socket, the shell mu...
