Description

A self-locking LED floodlight angle adjustment mechanism Technical Field

[0001] This utility model relates to the field of LED floodlight technology, and more specifically, to a self-locking LED floodlight angle adjustment mechanism. Background Technology

[0002] LED floodlights are high-brightness, high-efficiency lighting devices widely used for outdoor and large-area indoor lighting needs. To meet different lighting requirements, they are favored for their advantages such as energy saving, environmental protection, and long lifespan. Some LED floodlights are equipped with angle adjustment mechanisms, allowing users to adjust the beam angle according to actual needs. This self-locking angle adjustment mechanism ensures that the set angle will not change easily, increasing the flexibility and stability of use.

[0003] Chinese Patent Publication No. CN222459404U discloses an angle adjustment mechanism for LED floodlights. It includes a support assembly, an adjustment assembly, and a projection assembly. The support assembly includes a support base, a mounting rod, and a limiting frame. The mounting rod is mounted on the support base, and the limiting frames are symmetrically arranged on both sides of the support base, each containing a sliding groove. The adjustment assembly includes a mounting box, the bottom of which is connected to the mounting rod, and both sides of the mounting box are movably connected to the limiting frames. The projection assembly is housed within the mounting box. This mechanism allows for flexible adjustment of the projection angle of the LED floodlight and the number of floodlights that can be activated, improving the applicability of the device and enabling it to function in various lighting scenarios. This invention is primarily applied to the angle adjustment of LED floodlights.

[0004] In practical use, existing LED floodlights lack an effective locking mechanism after angle adjustment, which makes them prone to angle shift due to external environmental factors (such as wind pressure and vibration), thus affecting the lighting effect. Therefore, a self-locking LED floodlight angle adjustment mechanism is proposed. Summary of the Invention

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide a self-locking LED floodlight angle adjustment mechanism. It achieves one-button unlocking, automatic reset locking, simple operation, rapid response, and reliable locking angle adjustment by setting a mechanical self-locking structure composed of a hand lever, sliding rod, spring, arc-shaped toothed block and toothed ring. This solves the problems of easy displacement after lamp angle adjustment, insecure locking, and inconvenient operation in the prior art.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A self-locking LED floodlight angle adjustment mechanism includes a U-shaped frame. An adjustment component is installed inside the U-shaped frame, and an angle adjustment component is installed on the outer surface of the U-shaped frame. The adjustment component includes a rotating rod rotatably connected to the inner cavity of the U-shaped frame. One end of the rotating rod is fixedly connected to an LED floodlight, and the other end of the rotating rod passes through the U-shaped frame and is fixedly connected to a positioning disc. A toothed ring is fixedly connected to the outer surface of the rotating rod. Fixed sleeves are symmetrically fixedly connected to both sides of the inner wall of the U-shaped frame. A sliding rod is slidably connected to the inner cavity of the fixed sleeve. An arc-shaped toothed block is fixedly connected to the upper end of the sliding rod. The angle adjustment component includes an annular sliding sleeve fixedly connected to the outer surface of the U-shaped frame. An annular groove is opened in the inner cavity of the annular sliding sleeve. Two connecting rods are symmetrically fixedly connected to the outer surface of the U-shaped frame.

[0010] Furthermore, the U-shaped frame has multiple mounting holes, and the LED floodlight is located in the middle of the inner cavity of the U-shaped frame.

[0011] Furthermore, a spring is fixedly connected to the lower end of the sliding rod, and the lower end of the spring is fixedly connected to the bottom of the inner cavity of the fixed sleeve.

[0012] Furthermore, the gear ring and the arc-shaped gear block are meshed together, and a hand lever is fixedly connected to the outer surface of the sliding rod.

[0013] Furthermore, the outer surface of the annular sliding sleeve is marked with scale lines, and the connecting rod moves within the annular groove cavity.

[0014] Furthermore, a circular pointer is fixedly connected to one end of the connecting rod, and the circular pointer moves on the outer surface of the annular sliding sleeve.

[0015] 3. Beneficial Effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this solution, the user moves the sliding rod downward in the fixed sleeve by pushing the lever downward with his hand, which compresses the spring. At this time, the arc-shaped toothed block disengages from the toothed ring and releases the self-locking, so the angle of the LED floodlight can be adjusted at will. Conversely, the arc-shaped toothed block remains engaged with the toothed ring under the action of the spring, so that the LED floodlight and the rotating rod are locked and cannot rotate freely. This ensures that the LED floodlight will not deviate due to external forces such as wind pressure and vibration after the set angle. The user only needs to push the lever to unlock quickly. The operation is simple and the response is fast. No additional tools are required.

[0018] (2) When the LED floodlight rotates, it will drive the connecting rod and the circular pointer to rotate. At this time, the user can compare the scale line on the ring sliding sleeve, so that the user can intuitively read and accurately control the rotation angle of the LED floodlight during the adjustment process. It is particularly suitable for stage lighting, building lighting and advertising lighting scenarios with high requirements for the direction of illumination. Through the cooperation of the ring sliding sleeve and the ring groove, it is ensured that the LED floodlight does not shake during the rotation process, avoiding angle deviation caused by shaking or offset, thereby further ensuring the accuracy and consistency of adjustment.

[0029] Example 1:

[0030] Please refer to Figures 1, 2, 3, and 5. A self-locking LED floodlight angle adjustment mechanism includes a U-shaped frame 1. An adjustment component 2 is installed inside the U-shaped frame 1. The adjustment component 2 includes a rotating rod 201 rotatably connected to the inside of the U-shaped frame 1. One end of the rotating rod 201 is fixedly connected to an LED floodlight 202. The other end of the rotating rod 201 passes through the U-shaped frame 1 and is fixedly connected to a positioning disc 203. A toothed ring 204 is fixedly connected to the outer surface of the rotating rod 201. Fixed sleeves 205 are symmetrically fixedly connected to both sides of the inner wall of the U-shaped frame 1. A sliding rod 206 is slidably connected to the inner cavity of the fixed sleeve 205. An arc-shaped toothed block 208 is fixedly connected to the upper end of the sliding rod 206.

[0031] Specifically, the U-shaped frame 1 has multiple mounting holes 101. As the basic support structure of the entire angle adjustment mechanism, the U-shaped frame 1 has multiple mounting holes 101 on its surface, which makes it easy to install the lamp on the wall, bracket or column by bolts or other fasteners. At the same time, the U-shaped frame 1 can also be used as a handheld part for users to hold. It is usually made of high-strength aluminum alloy or stainless steel, which has good corrosion resistance, weather resistance and mechanical strength, and is suitable for outdoor and harsh environments.

[0032] The LED floodlight 202 is located in the middle of the inner cavity of the U-shaped frame 1. A spring 207 is fixedly connected to the lower end of the sliding rod 206. The lower end of the spring 207 is fixedly connected to the bottom of the inner cavity of the fixed sleeve 205. The toothed ring 204 and the arc-shaped toothed block 208 are engaged. A hand lever 209 is fixedly connected to the outer surface of the sliding rod 206. Under the action of the spring 207, the arc-shaped toothed block 208 is engaged with the toothed ring 204, so that the LED floodlight 202 and the rotating rod 201 are locked and cannot rotate freely, ensuring that the LED floodlight 202 will not deviate due to external forces such as wind pressure and vibration after the set angle.

[0033] When the angle needs to be adjusted, the user moves the lever 209 downwards, causing the sliding rod 206 to move downwards within the fixed sleeve 205, compressing the spring 207. At this time, the arc-shaped toothed block 208 disengages from the toothed ring 204, releasing the self-locking mechanism, allowing the angle of the LED floodlight 202 to be adjusted arbitrarily. The rotating rod 201 connects the LED floodlight 202 and the U-shaped frame 1, serving as the core shaft for the rotation adjustment of the lamp. It is made of high-quality carbon steel or stainless steel, and the surface is anodized or galvanized to enhance wear resistance and corrosion resistance. The user only needs to move the lever 209 to quickly unlock the lamp, making the operation simple and responsive, without the need for additional tools.

[0034] Example 2:

[0035] Please refer to Figures 1, 2 and 4. A self-locking LED floodlight angle adjustment mechanism also includes an angle adjustment component 3 installed on the outer surface of a U-shaped frame 1. The angle adjustment component 3 includes an annular sliding sleeve 301 fixedly connected to the outer surface of the U-shaped frame 1. An annular sliding groove 302 is opened in the inner cavity of the annular sliding sleeve 301. Two connecting rods 303 are symmetrically fixedly connected to the outer surface of the U-shaped frame 1.

[0036] Specifically, the outer surface of the annular sliding sleeve 301 is marked with scale lines, the connecting rod 303 moves in the inner cavity of the annular sliding groove 302, and a circular pointer 304 is fixedly connected to one end of the connecting rod 303. The circular pointer 304 moves on the outer surface of the annular sliding sleeve 301. When the LED floodlight 202 rotates, it will drive the connecting rod 303 and the circular pointer 304 to rotate. At this time, the user can compare with the scale lines on the annular sliding sleeve 301, so that the user can intuitively read and accurately control the rotation angle of the LED floodlight 202 during the adjustment process. It is particularly suitable for stage lighting, architectural lighting and advertising lighting scenarios with high requirements for the direction of light.

[0037] The annular sliding sleeve 301 and the annular sliding groove 302 work together to ensure that the LED floodlight 202 does not wobble during rotation, thus avoiding angular deviation caused by wobbling or offset, and further ensuring the accuracy and consistency of adjustment.

[0038] Working principle: During use, the U-shaped frame 1 has multiple mounting holes 101 on its surface, facilitating the installation of the lamps on walls, brackets, or columns using bolts or other fasteners. The U-shaped frame 1 can also be used as a handheld component. When in use, the arc-shaped toothed block 208, under the action of the spring 207, remains engaged with the toothed ring 204, locking the LED floodlight 202 and the rotating rod 201, preventing free rotation. This ensures that the LED floodlight 202 will not shift due to external forces such as wind pressure or vibration after being set at the desired angle. When angle adjustment is needed, the user manually moves the lever 209 downwards, causing the sliding rod 206 to move downwards within the fixed sleeve 205, compressing... Spring 207, at this time the arc-shaped toothed block 208 disengages from the toothed ring 204, releasing the self-locking, and the angle of the LED floodlight 202 can be adjusted arbitrarily. The user only needs to move the hand lever 209 to quickly unlock it. When the LED floodlight 202 rotates, it will drive the connecting rod 303 and the circular pointer 304 to rotate. At this time, the user can compare with the scale line on the annular sliding sleeve 301, so that the user can intuitively read and accurately control the rotation angle of the LED floodlight 202 during the adjustment process. It is particularly suitable for stage lighting, architectural lighting and advertising lighting scenarios with high requirements for the direction of illumination. Through the cooperation of the annular sliding sleeve 301 and the annular slide groove 302, it is ensured that the LED floodlight 202 does not wobble during rotation.

[0039] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
