Abstract
Description
Technical Field
[0001] The utility model relates to an expansion device, in particular to an expansion device for a light strip. Background Art
[0002] In traditional aluminum alloy light strips, there is a long strip-shaped structure as a fixing medium. The production difficulty of this structure lies in that the material of aluminum is too soft, so it is difficult to avoid errors during the processing. For aluminum alloy light strips, the heat sinks on their tops not only have a long distance but also a height far exceeding the conventional design of aluminum alloy. Therefore, the errors will be infinitely amplified during production, resulting in a very high unqualified rate of the finished products. And these errors are divided into being larger than the standard and smaller than the standard. If it exceeds the standard, it only needs to be clamped. Even though it is time-consuming and laborious for manual work, it is still operable. However, if it is smaller than the standard, it will be difficult for manpower to expand it, and it is also very difficult to complete the standardized operation.
[0003] To solve the above problems, a series of improvements have been made. Summary of the Utility Model

[0019] Figure 1 It is a structural schematic diagram of the present utility model.
[0020] An expansion device for a light belt, comprising: a mounting plate 100, a stretching cylinder 200, a component fixing plate 300, an expansion structure 400, a light belt fixing plug 500, a guiding shaft 600, and a limiting shaft 700. The component fixing plates 300 are symmetrically arranged on the left and right sides of the mounting plate 100. The stretching cylinders 200 are arranged at the front and rear ends of the mounting plate 100. The transmission shafts of the stretching cylinders 200 are connected to the expansion structure 400. The light belt fixing plug 500 is arranged at the center of the mounting plate 100 and is connected to the light belt 800 during use. One ends of the guiding shaft 600 and the limiting shaft 700 are connected to the component fixing plate 300, and the other ends of the guiding shaft 600 and the limiting shaft 700 are connected to the expansion structure 400. The expansion structure 400 is connected to the light belt 800 during use;
[0021] Among them, the expansion structure 400 includes an expansion connecting piece 410 and an L-shaped plug-in structure 420. The L-shaped plug-in structure 420 is an L-shaped structure. The bottom surface of the L-shaped plug-in structure 420 is connected to the expansion connecting piece 410, and the vertical surface of the L-shaped plug-in structure 420 is connected to the light strip 800 during use. The expansion connecting piece 410 is connected to the stretching cylinder 200, the guide shaft 600, and the limit shaft 700.
[0022] The light strip fixing plug-in 500 is an L-shaped structure. The bottom surface of the light strip fixing plug-in 500 is fixedly connected to the mounting plate 100, and the vertical surface of the light strip fixing plug-in 500 is connected to the light strip 800.
[0023] One end of the guide shaft 600 is provided with a bearing 610.
[0024] The limit shaft 700 is a bolt structure. One end of the limit shaft 700 is connected to the expansion connecting piece 410, the other end of the limit shaft 700 is movably connected to the component fixing plate 300, and a nut 710 is provided at the other end of the limit shaft 700, and the nut 710 is arranged inside the connection between the limit shaft 700 and the component fixing plate 300.
[0025] The working principle of the present utility model is as follows: The light strip 800 is placed into the light strip fixing plug-in 500 and is limited by the light strip fixing plug-in 500. The light strip fixing plug-in 500 is an L-shaped structure and is only connected to the edges on both sides of the light strip 800. The top of the light strip has a symmetrical groove structure. When expanding, it needs to be inverted so that the groove structures at the top are respectively connected to the symmetrical light strip fixing plug-ins 500 in an insertion manner. In this fixed state, one side of the top of the light strip fixing plug-in 500 is connected to the light strip 800, and there is a space on the other side of the top of the light strip fixing plug-in 500, forming a form similar to a sliding connection. At the same time, one side of the L-shaped plug-in structure 420 of the expansion structure 400 is also the same as the light strip fixing plug-in 500 and is connected to the top of the light strip 800 in an insertion manner. The L-shaped plug-in structure 420 is in close contact with the light strip fixing plug-in 500, and the contact surface of the L-shaped plug-in structure 420 completely fills the top slot of the light strip 800.
[0026] After the fixation is completed, the stretching cylinder 200 is started. The stretching cylinder 200 uses the transmission shaft to stretch the expansion structure 400 outwards. The expansion structure 400 moves horizontally from the center to both sides through the guide shaft 600 with the bearing 610. Since the movement of the stretching cylinder 200 is set to block and stop, it is also necessary to limit the stroke of the stretching cylinder 200 within a reasonable range through the limit shaft 700 and the nut 710. Subsequently, the stretching cylinder 200 stretches the expansion connecting piece 410, the expansion connecting piece 410 drives the L-shaped plug-in structure 420, and the L-shaped plug-in structure 420 stretches the grooves on both sides of the top of the light strip, and expansion is completed during this process.
[0027] In this process, the guiding shaft 600 realizes the movement from the center to both sides through the bearing 610; the limiting shaft 700 and the nut 710 achieve the limiting function. The principle is that the nut 710 controls the entire movable distance of the limiting shaft 700 by tightening the inner connection point between the limiting shaft 700 and the component fixing plate 300. The limiting shaft 700 itself is movably connected to the component fixing plate 300, and the pushing distance is the distance from the nut 710 of the limiting shaft 700 to the component fixing plate 300. Therefore, through this principle, the entire movable distance of the limiting shaft 700 is realized, and thus it becomes the structure with the shortest stroke in the entire transmission process. Therefore, the nut 710 bears the resistance for the expansion structure 400, thereby playing the role of stopping the machine, and finally realizing the control of the expansion effect.
[0028] Compared with the traditional technology, the present utility model realizes high-precision correction processing by designing an expansion device for large long strip light belts, thereby improving the quality of the products.
[0029] The specific embodiments of the present utility model have been described above, but the present utility model is not limited thereto. As long as it does not depart from the purpose of the present utility model, the present utility model can have various changes.
