Description

Technical Field

[0001] This utility model relates to the field of courtyard lights, and more specifically, to an LED courtyard light that can be adjusted at multiple angles. Background Technology

[0002] In the current field of courtyard lighting, most courtyard lights adopt a fixed structure. The fixed lighting angle of these lights makes it difficult to meet diverse lighting needs. For example, when hosting parties or gardening activities in the courtyard, it is necessary to focus the light on specific areas. Fixed courtyard lights cannot flexibly adjust the direction of the light, resulting in poor lighting effects. Furthermore, some courtyards have complex terrain, making it difficult for fixed-angle courtyard lights to fully cover the illuminated area, creating blind spots.

[0003] The few garden lights with directional adjustment functions mostly have their adjustment mechanisms located externally. These external adjustment mechanisms are exposed to the natural environment for extended periods, making them susceptible to corrosion from wind, sun, and rain, leading to rust and damage to components, thus affecting the lifespan and stability of the adjustment mechanism. Moreover, external adjustment mechanisms detract from the overall aesthetics of the garden light and are easily subject to external impacts during daily use, causing the adjustment function to malfunction.

[0004] How to invent a multi-angle adjustable LED garden light to improve these problems has become an urgent issue for those skilled in the art. Utility Model Content

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a multi-angle adjustable LED courtyard light, including a base 1, with a lamp post 2 rotatably connected to the upper end of the base 1 via a connecting adjustment assembly 3. An LED lamp body 4 is mounted at the top of the lamp post 2. The base 1 includes a cylindrical seat 101, with a recessed mounting cavity 103 on the upper surface of the cylindrical seat 101. An annular protrusion 102 is also coaxially provided on the upper end surface of the cylindrical seat 101. The connecting adjustment assembly 3 includes an annular sleeve 301 and a rotating shaft 302. The annular sleeve 301 is rotatably mounted on the outside of the annular protrusion 102, and the bottom end of the lamp post 2 is located inside the annular sleeve 301. The top end of shaft 302 is fixedly connected to the bottom end of lamp post 2. The bottom end of shaft 302 is rotatably mounted on the inner wall of the bottom of mounting cavity 103. A driven gear 303 is fixedly sleeved on shaft 302. A gear ring 304 is provided on the inner wall of annular sleeve 301 at a height corresponding to the driven gear 303. A transmission gear 305 is provided between the driven gear 303 and the gear ring 304. The transmission gear 305 meshes with both the driven gear 303 and the gear ring 304. The transmission gear 305 is rotatably sleeved on the top end of mounting shaft 306. A cavity 307 is provided inside mounting shaft 306. An elastic limiting mechanism is provided in cavity 307.

[0024] Please see Figures 2 to 4The elastic limiting mechanism includes a plurality of friction limiting blocks 308 evenly distributed in a ring in the cavity 307. The top of each friction limiting block 308 is rotatably connected to the top inner wall of the cavity 307 via a hinge. A connecting port 309 is provided through the inner wall of the cavity 307 corresponding to the position of each friction limiting block 308. The bottom end of each friction limiting block 308 extends through the corresponding connecting port 309 to the outer wall of the mounting shaft 306 and abuts against the inner wall of the transmission gear 305. A limiting and unlocking mechanism is provided between the plurality of friction limiting blocks 308.

[0025] The elastic limiting mechanism is used to limit the transmission gear 305. Friction is generated by the friction limiting block 308 abutting against the inner wall of the transmission gear 305, preventing the transmission gear 305 from rotating and thus locking the angle of the lamp post 2. The limiting unlocking mechanism controls the working state of the friction limiting block 308, realizing the release and restoration of the limit. The friction limiting block 308 is made of a material with a high coefficient of friction, such as rubber or polyurethane. Its top end is connected to a hinge via a pin, and the hinge is fixed to the inner wall of the top of the cavity 307. The dimensions of the connecting port 309 are designed to ensure that the friction limiting block 308 can pass smoothly and can tightly abut against the transmission gear 305 during operation. The elastic limiting mechanism can achieve stepless limiting, effectively limiting the transmission gear 305 regardless of its angle, improving the flexibility and accuracy of the lamp post 2 angle adjustment. Simultaneously, the friction-based limiting can buffer external impacts to a certain extent, protecting the transmission components.

[0026] Furthermore, the bottom end of the mounting shaft 306 is fixedly connected to the bottom inner wall of the mounting cavity 103. Below the mounting cavity 103, inside the cylindrical base 101, there is also an operating cavity 104. The top inner wall of the operating cavity 104 and the bottom inner wall of the mounting cavity 103 are connected through a through hole. The limiting and unlocking mechanism includes a frustum abutment block 310. The frustum abutment block 310 is located between several friction limiting blocks 308 and is coaxially arranged with the mounting shaft 306. One end of the connecting rod 311 is fixedly connected to the bottom surface of the frustum abutment block 310. The connecting rod 311 is slidably connected in the through hole and its bottom end extends through the through hole into the operating cavity 104 and is fixedly connected to a circular plate 312. A limiting spring 313 is fixedly connected between the circular plate 312 and the bottom inner wall of the operating cavity 104. A pedal 314 is integrally provided on one outer wall of the circular plate 312.

[0027] The limiting and unlocking mechanism controls the position of the frustum abutment block 310 to open and release the friction limiting block 308, thereby controlling the working state of the elastic limiting mechanism. When unlocking is required, the pedal 314 is pressed, causing the circular plate 312, connecting rod 311, and frustum abutment block 310 to move downwards, separating the friction limiting block 308 from the transmission gear 305. When limiting is required, the pedal 314 is released, and under the action of the limiting spring 313, the frustum abutment block 310 moves upwards, causing the friction limiting block 308 to abut against the transmission gear 305. The frustum abutment block 310, connecting rod 311, circular plate 312, and pedal 314 are all made of metal, such as stainless steel. The inner wall of the through hole is smooth to ensure smooth sliding of the connecting rod 311. The limiting spring 313 is selected with appropriate spring stiffness to ensure that the frustum abutment block 310 is held in the working position when no external force is applied, and to be smoothly compressed when the pedal 314 is pressed. The foot-operated limit unlocking mechanism is easy to operate. Users can easily lock and unlock the light pole at two angles without the need for tools, which improves the convenience of use.

[0028] Furthermore, the diameter of the bottom surface of the frustum abutment block 310 is larger than the diameter of the top surface.

[0029] The design of the frustum-shaped abutment block 310, with its bottom surface diameter larger than its top surface diameter, ensures more effective separation of the friction limit block 308 from the transmission gear 305 during downward movement; and more stably ensures the friction limit block 308 abuts tightly against the transmission gear 305 during upward movement, guaranteeing the limiting effect. This optimizes the working performance of the limiting and unlocking mechanism, improving the reliability of the limiting and the thoroughness of unlocking.

[0030] Furthermore, the number of friction limit blocks 308 is at least three.

[0031] The more friction limit blocks 308 there are, the better the limiting stability of the elastic limiting mechanism can be guaranteed. Multiple friction limit blocks 308 are evenly distributed and can apply frictional force to the transmission gear 305 from multiple directions to prevent it from rotating. Increasing the number of friction limit blocks 308 can enhance the limiting ability of the elastic limiting mechanism and improve the stability of the angle locking of the lamp post 2.

[0032] Furthermore, a torsion spring structure is provided between the top of each friction limit block 308 and the hinge.

[0033] The torsion spring structure provides a relatively stable initial position for the friction limiting block 308, so that when it is not acted upon by the frustum abutment block 310, it can both disengage from the inner wall of the transmission gear 305 and remain in a suitable position to wait for the frustum abutment block 310 to rise and abut against it again, thereby reducing motion interference caused by improper positioning and improving stability during operation.

[0034] Furthermore, an operating port corresponding to the operating cavity 104 is provided on one side of the outer wall of the cylindrical base 101, and a sealing door 105 is rotatably connected to one side edge of the operating port.

[0035] The sealing door 105 protects the components inside the operating chamber 104 from dust, rainwater, and other contaminants that could affect the normal operation of the limit unlocking mechanism. Simultaneously, the sealing door 105 can be easily opened when operation is required. The sealing door 105 is made of the same material as the cylindrical base 101 and is connected to one edge of the operating opening via a hinge. When closed, it can be sealed using a rubber sealing strip or similar material. This extends the service life of the limit unlocking mechanism and ensures its operational stability and reliability.

[0036] Furthermore, a ground plate 106 is fixedly connected to the bottom surface of the cylindrical base 101.

[0037] The base plate 106 is used to firmly fix the base 1 to the ground, ensuring that the garden light will not shake or tip over during use. The base plate 106 is made of a large-sized metal plate and is fixed to the ground by expansion bolts or anchor bolts. This improves the overall stability and safety of the garden light.

[0038] Furthermore, the annular sleeve 301 is coaxially provided with a gripping part 315, which is fixedly connected to the outer wall of the annular sleeve 301.

[0039] The grip 315 allows users to manually rotate the annular sleeve 301 to adjust the angle of the lamp post 2. The grip 315 is made of plastic or rubber, and its surface can be designed with anti-slip textures to increase friction and facilitate gripping. The grip 315 is integrally formed and fixedly connected to the outer wall of the annular sleeve 301. This improves the ease of operation for users adjusting the angle of the lamp post 2, making the adjustment process easier and more comfortable.

[0040] Working principle: When it is necessary to adjust the angle of the lamp post 2, first open the sealing door 105 on one side of the cylindrical base 101, and step down the pedal 314 on one side of the circular plate 312 inside the operating cavity 104. The pedal 314 drives the circular plate 312, the connecting rod 311, and the frustum abutment block 310 to move downward, so that the frustum abutment block 310 disengages from the friction limit block 308. The friction limit block 308 separates from the inner wall of the transmission gear 305, releasing the limitation on the transmission gear 305. Then, the user rotates the annular sleeve 301 through the grip 315. The teeth on the inner wall of the annular sleeve 301... The ring 304 drives the transmission gear 305 to rotate, which in turn drives the driven gear 303 and the rotating shaft 302 fixedly connected to the driven gear 303 to rotate, thereby realizing the rotation of the lamp post 2. When the lamp post 2 rotates to the required angle, the pedal 314 is released. Under the action of the limiting spring 313, the frustum abutment block 310 moves upward. The friction limiting block 308, under the action of the torsion spring structure and the frustum abutment block 310, tightly abuts against the inner wall of the transmission gear 305, using friction to prevent the transmission gear 305 from rotating, thereby locking the angle of the lamp post 2. At the same time, the LED lamp body 4 can be adjusted vertically through the adjusting bracket. When adjusting, the positioning pin is pulled out, the angle is adjusted, and then it is inserted into the corresponding positioning hole for fixation.

[0041] It should be noted that the specific model and specifications of the LED lamp body 4 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0042] The power supply and principle of the LED lamp body 4 are clear to those skilled in the art, and will not be described in detail here.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
