Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components alone, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present utility model can be combined with each other without conflicting with each other.

[0026] Referring to Figures 1 to 4 , the present utility model provides a lamp tube extension assembly, which is applied to the splicing and extension assembly of strip lights. Using the lamp tube extension assembly of the present utility model, users can customize the length requirements according to their own needs. Its structure is simple, and the splicing and installation process is simple and fast. It includes a first lamp tube 1, a second lamp tube 2 and a connecting member. The first lamp tube 1 has a first lamp strip installation cavity 11 inside, and the second lamp tube 2 has a second lamp strip installation cavity 21 inside. The connecting member is respectively slidably connected inside the first lamp tube 1 and the second lamp tube 2 to realize the splicing of the first lamp tube 1 and the second lamp tube 2. In this embodiment, the first lamp tube 1 includes a first lamp cover and a first base tube, and the first lamp cover is clamped and covered on the first base tube to form the first lamp strip installation cavity 11; the second lamp tube 2 includes a second lamp cover and a second base tube, and the second lamp cover is clamped and covered on the second base tube to form the second lamp strip installation cavity 21. When in use, the lamp strip is installed in the first lamp strip installation cavity 11 and the second lamp strip installation cavity 21. The first lamp tube 1 and the second lamp tube 2 can also be in other structural forms, which are not uniquely limited here. The lamp tube extension assembly also includes conventional structures such as lamp caps. After the extension installation of the second lamp tube 2 is completed, the lamp cap is snapped and installed at the end of the second lamp tube 2 to close the end of the second lamp tube 2.

[0027] Reference Figure 1 、 Figure 2 and Figure 3 , a first chute 12 is provided in the first lamp tube 1, a second chute 22 is provided in the second lamp tube 2, and the connecting member is respectively slidably connected to the first chute 12 and the second chute 22. An elastic clamping portion 34 is provided on the connecting member, a first clamping hole 13 is correspondingly provided on the first lamp tube 1, and second clamping holes 23 are symmetrically provided at both ends of the second lamp tube 2. When the connecting member slides in the first chute 12 such that the elastic clamping portion 34 is clamped in the first clamping hole 13, the connecting member is fixedly connected to the first lamp tube 1; when the sliding portion 33 slides in the second chute 22 such that the elastic clamping portion 34 is clamped in the second clamping hole 23, the connection between the connecting member and the second lamp tube 2 is fixed. When splicing the first lamp tube 1 and the second lamp tube 2, the two ends of the connecting member are respectively connected to the first lamp tube 1 and the second lamp tube 2, so that the elastic clamping portion 34 is clamped and fixed to both the first clamping hole 13 and the second clamping hole 23, and the installation connection between the first lamp tube 1 and the second lamp tube 2 can be realized. The first lamp tube 1 and the floor lamp base 4 are fixedly connected at the factory. Second clamping holes 23 are symmetrically provided at both ends of the second lamp tube 2. Users can splice one or more second lamp tubes 2 through the connecting member according to their needs to realize the extension of the lamp tubes.

[0028] Reference Figures 2 to 4 , further, the connecting member is a connecting elastic piece 3. The connecting elastic piece 3 includes a flat portion 31 and a supporting portion 32. The supporting portion 32 is bent and extended downward from both sides of the flat portion 31. The flat portion 31 is the base of the connecting elastic piece 3. The supporting portion 32 is used to strengthen the connection stability of the connecting elastic piece 3. During installation, the flat portion 31 and the supporting portion 32 are closely attached to the inner walls of the first lamp tube 1 and the second lamp tube 2. Sliding portions 33 are horizontally extended from the supporting portions 32 on both sides respectively. Correspondingly, two first chutes 12 are symmetrically provided in the first lamp tube 1, and two second chutes 22 are symmetrically provided in the second lamp tube 2. The sliding portions 33 are slidably connected to the first chutes 12 and the second chutes 22. In this embodiment, the flat portion 31, the supporting portion 32 and the sliding portion 33 are connected to form a connecting elastic piece 3 in a "ji" - shaped structure. During use, the flat portion 31 and the supporting portion 32 are closely attached to the inner walls of the first lamp tube 1 and the second lamp tube 2, effectively enhancing the connection strength of the connecting elastic piece 3, ensuring that the connecting elastic piece 3 can effectively support the connection part after connecting the first lamp tube 1 and the second lamp tube 2, and there will be no shaking during use.

[0029] Furthermore, the sliding portion 33 is in a "J"-shaped structure, and the corresponding first slide groove 12 and second slide groove 22 are both opened as a "C"-shaped structure. The sliding portion 33 is used in conjunction with the first slide groove 12 and the second slide groove 22 to limit the sliding of the connecting spring piece 3, which can effectively ensure that the connecting spring piece 3 will not be separated from the first lamp tube 1 or the second lamp tube 2 during the process of sliding into the first light bar installation cavity 11 or the second light bar installation cavity 21, further ensuring the connection reliability of the connecting spring piece 3.

[0030] The elastic clamping portion 34 is clamped in the first clamping hole 13 and the second clamping hole 23 to realize the connection and fixation between the connecting piece and the first lamp tube 1 and the second lamp tube 2. The elastic clamping portion 34 includes at least two symmetrically arranged elastic arms 341, and the elastic arms 341 are fixedly provided with a limiting clamping block 342. Accordingly, at least one first clamping hole 13 is provided on the first lamp tube 1, and at least one second clamping hole 23 is provided at each end of the second lamp tube 2. The limiting clamping block 342 is respectively clamped in the first clamping hole 13 and the second clamping hole 23 to realize the connection and fixation between the connecting spring 3 and the first lamp tube 1 and the second lamp tube 2.

[0031] In this embodiment, the elastic clamping portion 34 is provided with four elastic arms 341, and four clearance gaps 311 are symmetrically opened in the length direction of the plane portion 31, and the four clearance gaps 311 are located on the same straight line. The four elastic arms 341 are respectively arranged in the four clearance gaps 311, and one end of the elastic arm 341 is fixedly connected to the plane portion 31, and the limiting block 342 is fixedly connected to the free end of the elastic arm 341. Correspondingly, two first clamping holes 13 are opened on the first lamp tube 1, and two second clamping holes 23 are correspondingly opened at both ends of the second lamp tube 2. Each limiting block 342 is respectively arranged in a one-to-one correspondence with the first clamping hole 13 and the second clamping hole 23.

[0032] The elastic arm 341 is disposed within the clearance notch 311. When installing the connecting spring piece 3, when the limiting block 342 is subjected to pressure from the first lamp tube 1 or the second lamp tube 2, the elastic arm 341 elastically bends toward the first light bar mounting cavity 11 or the second light bar mounting cavity 21 until the limiting block 342 slides to the first engaging hole 13 or the second engaging hole 23. At this point, the elastic force of the elastic arm 341 drives the limiting block 342 to engage with the first engaging hole 13 or the second engaging hole 23, thereby securing the connecting spring piece 3 to the first lamp tube 1 or the second lamp tube 2. To remove the second lamp tube 2, simply press the limiting block 342 while sliding the connecting spring piece 3 to disengage the limiting block 342 from the first engaging hole 13 or the second engaging hole 23, allowing the second lamp tube 2 to be quickly removed.

[0033] Further, the top end of the limit clamping block 342 is provided with an arc-shaped structure. By setting the top end of the limit clamping block 342 as an arc-shaped structure, when the elastic clamping block slides to the first clamping hole 13 or the second clamping hole 23, the arc-shaped structure can guide the elastic clamping block, so that under the action of the elastic arm 341, the elastic clamping block can be more easily clamped into the first clamping hole 13 or the second clamping hole 23, reducing the clamping difficulty.

[0034] Further, the flat portion 31, the support portion 32, the sliding portion 33 and the elastic clamping portion 34 of the connecting elastic sheet 3 are integrally formed by stamping, with low processing cost and low manufacturing difficulty. In addition, the connecting elastic sheet 3 can be made of materials such as metal elastic sheets that have a certain elasticity and relatively high connection strength. The structures of the connecting elastic sheet 3 in the present utility model are symmetrically arranged in the length direction, without distinction between left and right structures. When in use, the user can install it without spending time distinguishing between left and right, effectively reducing the installation difficulty and saving installation time.
