[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0022] Please refer to Figures 1 to 5 A T8 daylight lamp support adapter device, including installing lamp 1 U-shaped support 2, U-shaped support 2 both ends are provided with sliding groove 201, two sliding grooves 201 symmetrically, two sliding grooves 201 are both slidingly connected with extension rod 3, two extension rods 3 are both connected with adapter 4 at the end away from each other, adapter 4 is in contact with the end of U-shaped support 2, and the end of extension rod 3 away from adapter 4 is connected with limiting assembly.

[0023] As Figures 1 to 5 The T8 daylight lamp support adapter device in the utility model is similar in structure to the prior art T8 daylight lamp support adapter device, such as the T5 to T8 conversion type LED support disclosed in the patent with publication number CN206419902U. The main improvement of the utility model is to improve the applicability of the adapter support, as shown in Figures 1 to 5 When the T8 daylight lamp support adapter device in the utility model is used, lamp 1 is installed on the inner side of U-shaped support 2, then according to the length specification of the T8 support to be adapted, adapter 4 at both ends of U-shaped support 2 is pulled, so that extension rod 3 is pulled out of sliding groove 201, and extension rod 3 is pulled out to the appropriate installation length of T8 support, then limiting assembly is used to limit extension rod 3, so as to avoid the retraction of extension rod 3 in sliding groove 201, finally the adapter device with the length adjusted is installed on T8 support through adapter 4 at both ends, wherein it is particularly pointed out that the driving power supply integrated in lamp 1 is used to balance the output voltage and power supply power between T8, so as to ensure that the adapted lamp 1 will not be damaged.

[0024] As Figures 1 to 3 Both ends of two sliding grooves 201 are provided with through holes. When impurities such as insects and dust enter sliding groove 201, the impurities in the inside can be pushed out from the through hole at the other end by pulling extension rod 3, so as to avoid the extension and retraction movement of extension rod 3 in sliding groove 201 being hindered.

[0025] As Figure 1 andFigure 2 As shown, a plurality of positioning holes 202 are arranged on the two sides of the U-shaped support 2 away from the U-shaped support 2. The plurality of positioning holes 202 are equidistantly arranged, and the limiting assembly is matched with the positioning holes 202. The positioning holes 202 matched with the limiting assembly are arranged on the top of the U-shaped support 2. After the U-shaped support 2 is installed on the T8 support, the limiting assembly and the positioning holes 202 can be shielded on the inner side of the T8 support, so as to avoid that the positioning holes 202 and the limiting assembly are touched by non-professionals by mistake, the positioning of the extension rod 3 is loosened, and the use safety of the adapter support is improved.

[0026] As shown in the figure, Figures 1 to 5 The distance between the two adjacent positioning holes 202 is 15 mm. By setting the distance between the plurality of positioning holes 202 on the sliding groove 201 to 15 mm, the two extension rods 3 can be pulled outwards at the same time, and the lengths of 30 mm, 60 mm or 90 mm can be formed, so that the extension lengths of the two ends of the U-shaped support 2 are ensured to be equal when the T8 supports with different lengths are adapted, the support forces provided by the two extension rods 3 are relatively uniform, and the service life of the extension rod 3 is improved.

[0027] As shown in the figure, Figures 1 to 5 The limiting assembly includes a positioning block 5 and a spring 6. The end of the extension rod 3 away from the adapter 4 and close to the positioning hole 202 is provided with an expansion hole 301. The positioning block 5 is slidably connected with the expansion hole 301. The end of the positioning block 5 in the expansion hole 301 is fixedly connected with the spring 6. The other end of the spring 6 is fixedly connected with the expansion hole 301. When the extension rod 3 needs to be pulled, the positioning block 5 can be pressed inwards from the positioning hole 202, so that the positioning block 5 is retracted into the expansion hole 301 and is separated from the positioning hole 202. At this time, the extension rod 3 can be pulled for extension or shortening operation. When the positioning block 5 moves to the position of the next positioning hole 202, the spring 6 can push the positioning block 5 outwards, so that the positioning block 5 is clamped into the positioning hole 202, and the position of the extension rod 3 is fixed.

[0028] As shown in the figure, Figure 5 The two sides of the expansion hole 301 are provided with limiting grooves 302. The two sides of the end of the positioning block 5 close to the spring 6 are fixedly connected with limiting blocks 7. The two limiting blocks 7 are slidably connected with the two limiting grooves 302. By limiting the sliding of the limiting block 7 in the limiting groove 302, when the spring 6 pushes the positioning block 5 upwards, the positioning block 5 is prevented from falling out of the expansion hole 301, and the connection between the positioning block 5 and the expansion hole 301 is ensured.

[0029] As shown in the figure, Figure 2 and Figure 3As shown, the two slide grooves 201 are provided with first wire grooves 203 on the adjacent sides, and the two extension rods 3 are provided with second wire grooves 303 on the sides close to the first wire grooves 203.

[0030] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model.
