Description

Technical Field

[0001] This utility model relates to the field of LED tube technology, specifically an LED tube with an expansion snap-fit ​​structure for easy assembly. Background Technology

[0002] In the modern lighting field, LED tubes are widely used in various lighting scenarios such as commercial venues, industrial plants, and residential homes due to their significant advantages such as energy saving, long lifespan, high brightness, and environmental friendliness. With the increasing popularity of LED tubes, the rationality and convenience of their installation methods and connection structures are receiving more and more attention.

[0003] Currently, common LED tube installation methods mainly include screw fixing, snap-fit ​​connection, and plug-in connection. While screw fixing provides a relatively stable connection, the installation process is cumbersome, requiring tools such as screwdrivers, consuming time and manpower. Furthermore, repeated disassembly and reassembly can easily damage the installation area, affecting the reliability of the installation. Snap-fit ​​connections simplify the installation process to some extent; however, the connection strength of snaps is limited. After vibration, external impact, or prolonged use, the snaps are prone to loosening or even breaking, leading to the risk of the LED tube falling off, posing a significant safety hazard. Plug-in connections offer faster installation, but require extremely high dimensional accuracy between the tube and the socket. Excessive plugging and unplugging can lead to poor contact, affecting the normal illumination of the LED tube and even causing circuit failure.

[0004] Furthermore, existing LED tube installation structures often lack sufficient flexibility and adaptability when dealing with different installation environments and needs. For example, in some industrial environments where installation stability is highly demanding, existing installation methods are difficult to meet the requirements of long-term, high-intensity use; while in places where frequent tube replacement is required, complex installation structures increase the difficulty and cost of replacement. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned technical defects and provide an LED tube with an expansion snap-fit ​​structure that is easy to assemble, is easy to install and disassemble, and is suitable for places where lamp tubes are frequently replaced.

[0006] To solve the above problems, the technical solution of this utility model is as follows: an LED tube with an expansion snap-fit ​​structure for easy assembly, including an LED tube and a mounting plate. One end of the LED tube is connected to a connecting seat by several bolts. The connecting seat is provided with an expansion mechanism inside. A mounting seat is fixedly connected to one side of the mounting plate, and an annular baffle is fixedly connected to one side of the mounting seat.

[0007] Furthermore, the expansion mechanism includes a servo motor, the output end of which is fixedly connected to a drive wheel, and a driven wheel is engaged on one side of the drive wheel. The drive wheel and the driven wheel rotate on the inner side of the connecting seat, and six evenly distributed arc-shaped grooves are formed on the drive wheel.

[0008] Furthermore, each of the six arc-shaped grooves is slidably connected with a limiting post, the size of which is just right to slide inside the six arc-shaped grooves, and the ends of each of the six limiting posts are fixedly connected with a limiting rod.

[0009] Furthermore, the connecting seat has six evenly distributed limiting grooves, the six limiting rods slide inside the six limiting grooves respectively, and the ends of the six limiting rods are respectively fixedly connected to arc-shaped expansion blocks.

[0010] Furthermore, anti-slip pads are fixedly connected to the outer surfaces of all six arc-shaped expansion blocks.

[0011] Furthermore, the diameter of the internal groove of the annular baffle is smaller than the diameter of the internal groove of the mounting base.

[0012] Furthermore, a lampshade is connected to the end of the LED tube.

[0013] The advantages of this invention compared to existing technologies are as follows:

[0014] 1. This utility model features an expansion mechanism. By activating a servo motor, its output drives the driving wheel to rotate. At this time, the engaged driven wheel begins to rotate, and the limiting posts inside the six arc-shaped grooves of the driven wheel begin to slide. This, in turn, drives the six limiting rods to slide within the six limiting grooves, achieving the contraction of the six arc-shaped expansion blocks. No screws or other tools are required; simply operating the servo motor to drive the expansion blocks to extend and engage with the mounting base allows for quick installation of LED tubes, significantly saving installation time and labor costs, and improving installation efficiency.

[0015] 2. This utility model has anti-slip pads on the outer surface of the six arc-shaped expansion blocks, which further increases the friction between them and the inner wall of the mounting base, ensuring that the LED tube can maintain a stable connection under various usage conditions and is not easy to loosen.

[0022] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0023] To make the content of this utility model easier to understand, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] like Figures 1 to 4 As shown, an LED tube with an expansion-type snap-fit ​​structure for easy assembly includes an LED tube 1 and a mounting plate 2. One end of the LED tube 1 is connected to a connecting seat 3 by several bolts. The connecting seat 3 has an expansion mechanism 4 inside. A mounting base 5 is fixedly connected to one side of the mounting plate 2, and an annular baffle 6 is fixedly connected to one side of the mounting base 5. The diameter of the internal groove of the annular baffle 6 is smaller than the diameter of the internal groove of the mounting base 5. A lampshade 8 is connected to the end of the LED tube 1. The design of the annular baffle 6 can provide a certain degree of protection for the connection parts inside the mounting base 5, preventing dust, impurities, etc. from entering and affecting the stability of the connection and the normal operation of the LED tube 1. The lampshade 8 can protect the LED tube 1 and improve its luminous effect and service life.

[0025] The expansion mechanism 4 includes a servo motor 401. The output end of the servo motor 401 is fixedly connected to a drive wheel 402. A driven wheel 403 is meshed on one side of the drive wheel 402. The drive wheel 402 and the driven wheel 403 rotate on the inner side of the connecting seat 3, respectively. The drive wheel 403 has six evenly distributed arc-shaped grooves 404. Each of the six arc-shaped grooves 404 has a slidably connected limiting post 405. The size of the six limiting posts 405 is just enough to slide inside the six arc-shaped grooves 404. Each of the ends of the six limiting posts 405 is fixedly connected to a limiting rod 406. The connecting seat 3 has six evenly distributed limiting grooves 407. The six limiting rods 406 slide inside the six limiting grooves 407, and each of the ends of the six limiting rods 406 is fixedly connected to an arc-shaped expansion block 408. By activating the servo motor 401, its output drives the driving wheel 402 to rotate. At this time, the engaged driven wheel 403 begins to rotate, and the limiting posts 405 inside the six arc-shaped grooves 404 in the driven wheel 403 begin to slide. This, in turn, drives the six limiting rods 406 to slide within the six limiting grooves 407, thereby achieving the contraction of the six arc-shaped expansion blocks 408. Without the need for screws or other tools, simply operating the servo motor 401 to drive the expansion blocks to extend and engage with the mounting base allows for quick installation of the LED tube 1, significantly saving installation time and labor costs and improving installation efficiency.

[0026] All six arc-shaped expansion blocks 408 have anti-slip pads 7 fixedly connected to their outer surfaces. The anti-slip pads 7 further increase the friction between them and the inner wall of the mounting base 5, ensuring that the LED tube 1 maintains a stable connection under various operating conditions and is not easily loosened.

[0027] In practical use, by starting the servo motor 401, its output end drives the driving wheel 402 to rotate. At this time, the meshing driven wheel 403 begins to rotate, and the limiting posts 405 inside the six arc-shaped grooves 404 in the driven wheel 403 all begin to slide, thereby driving the six limiting rods 406 to slide inside the six limiting grooves 407 respectively, realizing the contraction of the six arc-shaped expansion blocks 408. At this time, the LED tube 1 is picked up and placed inside the mounting base 5. The servo motor 401 is started again to rotate its output end in the opposite direction, and the six arc-shaped expansion blocks 408 begin to extend outward until they are tightly against the inner wall of the connecting base 5, thus realizing the installation of the LED tube 1. The anti-slip pad 7 further increases the friction between itself and the inner wall of the mounting base 5, ensuring that the LED tube 1 can maintain a stable connection under various operating conditions and is not easy to loosen.

[0028] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
