Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1, 2 and 3, a connection end for a lamp tube comprises an end sleeve and an end cover, wherein a bolt hole is formed in the inner side of the end sleeve, two groups of connecting grooves are formed in the outer wall of the end sleeve, a groove opening is formed in one end of each connecting groove, the connecting grooves are close to groove walls of the groove wall on one side of each groove opening and incline to the other side of each groove opening, one side of the end cover is used for being sleeved outside the end sleeve, the other side of the end cover is provided with a PG head, and the inner wall on one side of the end cover corresponds to.

When the lamp is used, one end of the end sleeve is sleeved at one end of the lamp tube, the lamp tube is correspondingly provided with the bolt hole, and the end sleeve is connected to the lamp tube through the bolt. The end cover is pressed to the pot head direction to spacing connecting block alignment notch back, and spacing connecting block gets into the spread groove back rotatory end cover, because the spread groove is smooth to be narrowed, and spacing connecting block blocks card promptly and establishes in the spread groove after the end cover is rotatory to a certain position, can't twist. The connection of end cover and pot head is accomplished promptly to spacing connecting block screw up in the spread groove after, the cooperation of spacing connecting block and spread groove makes the end cover can't become flexible when receiving the axial force, and the frictional force of spacing connecting block and spread groove makes the end cover need certain power of twisting just can open, and the fluorescent tube is generally fixed to be used, can not receive and twist power, and the cooperation of consequently spacing connecting block and spread groove can be accomplished the end cover and is connected fixedly with the pot head. The height of the limiting connecting block is set according to actual conditions, namely the rotation angle of the end cover can be limited, and in the embodiment, the end cover can rotate by ninety degrees. In fact, the opposite side of end cover has been seted up the through wires mouth, the through wires mouth department is provided with waterproof gasket, the PG head passes through the nut to be connected on the end cover and supports to press on waterproof gasket, the one end of PG head is worn to establish in the end cover and is connected through the nut, and the part that PG head is outside the end cover supports to press on waterproof gasket, and waterproof gasket is the rubber gasket actually.

In this embodiment, the lateral wall of the end cover is evenly provided with anti-skidding grooves, so that the end cover can be conveniently screwed.

Preferably, this a connection end for fluorescent tube still includes waterproof endotheca, waterproof endotheca includes barrel and ring type piece, the ring type piece sets up the one end of barrel just sets up with the barrel is coaxial, the axial equipartition has a plurality of ribs on the barrel outer wall, and the ring type piece of waterproof endotheca sets up in the end cover, and the distance between the outer wall of a plurality of ribs and the end cover inner wall equals the wall thickness of end cover. When the end cover is sleeved on the end sleeve, the inner wall of the end cover is abutted against the outer wall of the end sleeve, and the surface of the rib is abutted against the inner wall of the end sleeve, so that the friction force is increased, and the tightened end cover is prevented from loosening. Meanwhile, the annular sheet is pressed on the port of the end sleeve to play a role in water prevention. In practice, the end cover is provided with a silica gel gasket on the end face of one side of the end cover, and when the end cover is screwed on the end cover, the ring-shaped sheet is pressed on the silica gel gasket, so that a waterproof effect is further achieved.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
