a long tube lamp structure comprises a lamp cap, a lamp tube, a stable support column and an LED lamp core; the stable support is fixed on the lamp cap, and the lamp cap is adhered to the lamp tube so as to extend the stable support into the lamp tube; the stabilizing support column is bidirectionally extended to form a connecting column, and two ends of the LED lamp wick are respectively connected with two adjacent connecting columns on the same side of the stabilizing support column; the top of the stabilizing support column is provided with a spiral metal frame which is abutted against the inner wall of the top end of the lamp tube to limit the support column from shaking.

Preferably, the top end of the stabilizing support is provided with a jack, and the end of the metal frame is inserted into the jack to be fixed on the stabilizing support.

Preferably, the lamp cap is provided with a stem, and the tail end of the stabilizing support column is fixed on the stem; the lamp tube is provided with a cavity, and the stem, the stabilizing support and the LED lamp wick are all positioned in the cavity when the lamp cap is adhered to the lamp tube.

Preferably, the diameter of the metal frame increases gradually from the top to the bottom.

Compared with the background technology, the utility model has the beneficial effects that:

the utility model provides a long tube lamp structure, which comprises a lamp cap, a lamp tube, a stabilizing support and an LED lamp wick, wherein a spiral metal frame is arranged at the top end of the stabilizing support, the tail end of the stabilizing support is fixed on a stem, the LED lamp wick is connected to the stabilizing support, and when the long lamp tube shakes, the metal frame at the top end of the stabilizing support is pressed to deform so as to buffer the shake of the long lamp tube, thereby avoiding the LED lamp wick from being unwelded due to integral shake. The scheme has the advantages of simple structure, compact connection, reasonable design and the like, so that the scheme is a product with both technical and economical properties.

The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

The technical scheme and the beneficial effects of the utility model are more clear and definite by further describing the specific embodiments of the utility model with reference to the drawings in the specification. The embodiments described below are exemplary by referring to the drawings for the purpose of illustrating the utility model and are not to be construed as limiting the utility model.

The preferred embodiments provided by the utility model are: as shown in fig. 1 to 3, a long tube lamp structure comprises a lamp cap 1, a lamp tube 2, a stabilizing support 3 and an LED lamp wick 4; the stabilizing support 3 is fixed on the lamp cap 1, and the lamp cap 1 is adhered to the lamp tube 2 so as to extend the stabilizing support 3 into the lamp tube 2;

the stabilizing support column 3 is bidirectionally extended with a connecting column 31, two ends of the LED lamp core 4 are respectively connected with two adjacent connecting columns 31 on the same side of the stabilizing support column 3, welding spots are arranged at the tail ends of the connecting columns 31 and used for connecting lamp cores, and the LED lamp cores 4 on the same side of the stabilizing support column 3 are connected with each other; the LED lamp wicks 4 on two sides of the top end position of the stabilizing support 3 are connected through wires 5, and the single-side LED lamp wicks 4 are respectively provided with wires 5 to be connected with the lamp cap 1 so as to form a current loop.

The top end 32 of the stabilizing support 3 extends to the top end of the lamp tube 2, the top end of the stabilizing support 3 is provided with a spiral metal frame 5, the diameter of the metal frame 5 gradually increases from the top end to the bottom end to match the shape of the end of the lamp tube, the cross section of the top end of the lamp tube 2 is semicircular, and the metal frame is abutted against the inner wall of the top end of the lamp tube to limit the support from shaking; the top of the stabilizing support 3 is provided with a jack, the jack extends into the stabilizing support, the metal frame is connected more firmly by increasing the depth of the jack, the metal frame is formed in a spiral shape by continuously bending a metal wire made of copper from top to bottom, and the end part of the metal frame is inserted into the jack to be fixed on the stabilizing support.
