Description

Technical Field

[0001] This utility model belongs to the field of lighting equipment technology, specifically relating to a device that facilitates the angle adjustment of outdoor lamps. Background Technology

[0002] Currently, various outdoor lighting fixtures, such as high-mast lights, tunnel lights, and floodlights, are widely used in stadiums, airports, railway bridges, docks, roads, tunnels, and other locations. During installation, most of these fixtures require on-site adjustment of the installation angle by installers. The vast majority of these adjustments are made by loosening or tightening screws and nuts on either side of the fixture's mounting arm. Some fixtures require two people to adjust the angle: one to hold the fixture to prevent rotation, and the other to tighten the screws and nuts, wasting installation time and reducing efficiency. Furthermore, when removing screws, installers wearing gloves are prone to losing them, increasing installation costs and time.

[0003] Improving installation efficiency and reducing labor costs are crucial for lowering project costs. From a product perspective, enhancing the ease of adjusting the installation angle of lighting fixtures can strengthen product competitiveness and extend its lifespan. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a device that facilitates the adjustment of the angle of outdoor lamps, which can achieve the adjustment of lamp angle without the aid of any tools, reducing the difficulty of installation and the time consumption, thereby reducing the labor cost of the project.

[0005] This utility model is achieved through the following technical solution:

[0006] A device for facilitating angle adjustment of outdoor lighting fixtures includes a lighting fixture body, a hanging arm, an adjusting gear, a side cover, a spring lock, a spring piece, and a pin. The outer walls of both sides of the lighting fixture body are symmetrically provided with a ring of fine teeth and side holes, and the inner walls of both sides of the lighting fixture body are symmetrically provided with side grooves. The spring piece is fitted into the side groove of the lighting fixture body. The side cover consists of a head at one end and a rod-shaped structure at the other end. The head has blind holes on both sides, and the rod-shaped structure has a through hole at its end. The spring lock is installed in the blind hole of the head of the side cover. The rod-shaped structure of the side cover passes sequentially through the adjusting gear, the hanging arm, the side hole of the lighting fixture body, and the spring piece.

[0007] Furthermore, the adjusting gear has a central mounting hole in the middle for passing through the rod-shaped structure of the side cover; the end face of the adjusting gear has an arc-shaped groove for accommodating the head of the hanging arm, and another section of the end face has fine teeth; the fine teeth mesh with the fine teeth on the outer wall of the lamp body.

[0008] Furthermore, the head shape of the hanging arm matches the internal contour of the adjusting gear, passes through the groove provided on the circumference of the end face of the adjusting gear, and is inserted into the interior of the adjusting gear; the hanging arm is also provided with a mounting hole for passing through the rod-shaped structure of the side cover.

[0009] Furthermore, the head of the side cover is a smooth disc-shaped structure that fits against the end face of the adjusting gear, and the diameter of the disc-shaped structure is equal to the diameter of the adjusting gear.

[0010] Furthermore, the spring latch is a component formed by bending a metal wire, with both ends inserted into the blind holes in the head of the side cover.

[0027] Example 1:

[0028] Reference Figures 1 to 5This embodiment provides a device for facilitating the angle adjustment of outdoor lighting fixtures, comprising: a lighting fixture body 1, a hanging arm 2, an adjusting gear 5, a side cover 6, a spring lock 7, a spring piece 8, and a pin 9; wherein, the outer walls of both sides of the lighting fixture body 1 are symmetrically provided with a ring of fine teeth and side holes, and the inner walls of both sides of the lighting fixture body 1 are symmetrically provided with side grooves; the upper end of the lighting fixture body 1 is connected to a power supply 3, and the lower end is connected to an optical component 4; the spring piece 8 is assembled in the side groove of the lighting fixture body 1; the spring piece 8 is a metal sheet with elasticity, and its height in its natural state is greater than the width of the side groove of the lighting fixture body 1, and assembly is achieved by extrusion deformation.

[0029] The adjusting gear 5 has a disc-shaped structure with a central mounting hole for the rod-shaped structure of the side cover 6 to pass through. The end face of the adjusting gear 5 has an arc-shaped groove on its circumference to accommodate the head of the hanging arm 2, and another section on its circumference has evenly distributed fine teeth. Fine teeth are also provided on the outer wall of the lamp body 1. The fine teeth of the adjusting gear 5 mesh with the fine teeth on the outer wall of the lamp body 1. When the spring lock 7 is engaged, the fine teeth of the adjusting gear 5 and the fine teeth of the lamp body 1 form a tight mesh, creating a circumferential limiting effect through mechanical interlocking between the tooth surfaces. This effectively resists accidental rotation caused by external forces such as strong winds and vibrations, ensuring a reliable fixed angle for the lamp. The meshing fine teeth are evenly distributed, and the interval between adjacent teeth corresponds to a fixed angle change. In this embodiment, 5° can be selected, giving the lamp angle adjustment a clear sense of positioning and repeatability, achieving precise angle control.

[0030] The side cover 6 consists of a smooth, disc-shaped head at one end and a rod-shaped structure at the other end. The disc-shaped head fits against the end face of the adjusting gear 5, and the diameter of the disc-shaped head is equal to the diameter of the adjusting gear 5. Blind holes are provided on both sides of the disc-shaped head, and a through hole is provided at the end of the rod-shaped structure. The spring lock 7 is installed in the blind hole of the head of the side cover 6. The rod-shaped structure of the side cover 6 passes through the adjusting gear 5, the hanging arm 2, the side hole of the lamp body 1, and the spring piece 8 in sequence. The pin 9 passes through the through hole at the end of the rod-shaped structure of the side cover 6. One end of the pin 9 is a ring structure, and the other end is a straight structure. It is fixed by bending the end of the straight structure.

[0031] The head shape of the hanging arm 2 matches the internal contour of the adjusting gear 5, passes through the groove provided on the circumference of the end face of the adjusting gear 5, and is inserted into the interior of the adjusting gear 5; the hanging arm 2 is also provided with a mounting hole for passing through the rod-shaped structure of the side cover 6.

[0032] The spring latch 7 is a component formed by bending a metal wire. Its two ends are locked in the blind holes at the head of the side cover 6. The spring latch 7 can rotate around the head of the side cover 6. When the spring latch 7 is pressed, it can be locked onto the front end surface of the lamp body 1 after elastic deformation.

[0033] The installation process of the device for facilitating the angle adjustment of outdoor lighting fixtures in this embodiment is as follows:

[0034] 1. Squeeze the spring piece 8 by hand to deform it so that its height is less than the width of the side groove of the lamp body 1, and press the spring piece 8 into the side groove of the lamp body 1;

[0035] 2. Use your hand to widen the opening of the spring lock 7, insert it into the blind holes on both sides of the head of the side cover 6, and then release it; due to the elasticity of the spring lock 7 itself, both ends of the spring lock 7 will be tightly locked in the blind holes;

[0036] 3. Place the head of the hanging arm 2 into the arc-shaped groove on the end face of the adjusting gear 5, and align the mounting hole of the head of the hanging arm 2 with the center mounting hole of the adjusting gear 5, so that the fine teeth of the adjusting gear 5 mesh with the fine teeth on the outer side wall of the lamp body 1; then, pass the rod-shaped structure of the side cover 6 through the center mounting hole of the adjusting gear 5, the mounting hole of the head of the hanging arm 2, and the side hole of the lamp body 1 from the outside in sequence; when the end of the rod-shaped structure passes through the lamp body 1 and contacts the inner spring piece 8, gently squeeze the spring piece 8 by hand to make room for the rod-shaped structure of the side cover 6, so that the through hole at its end is fully exposed. Insert the pin 9 into the through hole; use tools such as needle-nose pliers to bend the other end of the pin 9 that extends out of the through hole into a round or oval shape, ensuring that it cannot accidentally slip out of the through hole;

[0037] 4. Rotate the spring latches 7 located on both sides of the lamp body 1 downwards so that they are locked onto the end face of the lamp body 1. At this time, the device is in the initial locked state.

[0038] Combination Figure 6 and Figure 7 The adjustment process of the device for facilitating the angle adjustment of outdoor lighting fixtures in this embodiment is as follows:

[0039] When it is necessary to adjust the illumination angle of the lamp, the operator uses his hand to pry open the spring lock 7 that is fastened to the end face of the lamp body 1, thereby releasing it from locking the lamp body 1.

[0040] Scenario 1 (Light fixture already fixed): If the hanging arm 2 is already fixedly installed on the bracket, the operator can directly rotate the main body 1 of the light fixture to the target illumination angle; after adjustment, the spring lock 7 is re-engaged on the end face of the main body 1 of the light fixture to complete the angle locking.

[0041] Scenario 2 (Light fixture not fixed): If the hanging arm 2 is not yet fixed, the operator can use one hand to stabilize the main body 1 of the light fixture and the other hand to rotate the hanging arm 2 to the target angle; after reaching the predetermined position, the spring lock 7 is also fastened to the end face of the main body 1 of the light fixture to achieve locking.

[0042] The mechanical transmission principle of the device for facilitating the angle adjustment of outdoor lighting fixtures in this embodiment is as follows:

[0043] The head structure of the hanging arm 2 and the internal contour of the adjusting gear 5 are designed with matching geometric shapes. When the head of the hanging arm is embedded in the adjusting gear, the two form a tight fit in the radial direction, ensuring that the hanging arm 2 and the adjusting gear 5 rotate synchronously. When the spring lock 7 is in the open state, the rotational torque applied by the operator is transmitted to the adjusting gear 5 through the hanging arm 2, causing the adjusting gear 5 to drive the entire assembly to rotate around the axis of the lamp body 1, while the side cover, spring plate, and spring lock do not rotate. During this process, the spring plate 8 undergoes elastic deformation, providing the necessary clearance for rotation. When the target angle is reached, the spring lock 7 is pressed down forcefully. After elastic deformation, the spring lock 7 can be locked onto the front end face of the lamp body 1.

[0044] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0045] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0046] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
