To meet the lighting needs of different construction areas, existing technology involves erecting multiple independent mounting frames at intervals within the construction work area and installing matching lighting systems on each frame. This increases construction costs, and each mounting frame occupies a certain amount of construction space, hindering the passage and operation of large construction machinery. Utility Model Content

Detailed Implementation

[0029] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0030] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a lighting device comprising a vertically arranged positioning rod 1 fixed to the ground. A vertically arranged guide rod 2 is connected to the upper part of the positioning rod 1, and the guide rod 2 rotates horizontally around the positioning rod 1. A ring bearing seat is fixed to the top of the positioning rod 1, and a bearing is embedded within the bearing seat. The outer ring of the bearing is fixed to the bearing seat, and the inner ring of the bearing is fixedly connected to the bottom of the guide rod 2. The guide rod 2 is rotatably connected to the positioning rod 1 via the bearing. A lighting lamp 3 is fixed to the guide rod 2. The rotation of the guide rod 2 adjusts the light emission angle of the lighting lamp 3. Each lighting device can illuminate different construction areas around it according to actual needs. Compared to the existing method of arranging multiple lighting devices at intervals to illuminate construction areas in different directions, this significantly reduces the number of lighting devices and the construction space occupied, thus lowering construction costs.

[0033] The outer surface of the guide rod 2 is provided with a spiral groove 402 extending from bottom to top. A driving structure is fixed on the positioning rod 1. The driving end of the driving structure is fixedly connected to a slide rod 45. The slide rod 45 is arranged horizontally, and the first end of the slide rod 45 is inserted into the spiral groove 402. The driving structure is used to drive the slide rod 45 to move up and down, so that the slide rod 45 presses against the groove wall of the spiral groove 402, thereby driving the guide rod 2 to rotate horizontally. The vertical movement of the slide rod 45 is converted into the horizontal rotation of the guide rod 2, thereby realizing stepless adjustment of the lighting direction. Moreover, when the driving structure stops, the slide rod 45 is fixed in the spiral groove 402 to form a self-locking structure, ensuring the fixation of the angle of the guide rod 2 and avoiding deviation caused by vibration or external force, further reducing the cost and maintenance requirements of the lighting device.

[0034] Specifically, the drive structure includes a motor 42, a lead screw 43, and a slider 44. The motor 42 is fixed on the positioning rod 1, the lead screw 43 is arranged vertically, the output shaft of the motor 42 is fixedly connected to the lead screw 43, the slider 44 is mounted on the lead screw 43, and the slide rod 45 is fixedly connected to the slider 44. The slider 44 and the vertical lead screw 43 form a lead screw-nut transmission structure. When the motor 42 drives the lead screw 43 to rotate, it drives the slider 44 to move up and down along the lead screw 43 through the threaded engagement, thereby driving the slide rod 45 to move up and down synchronously. The slide rod 45 is inserted into the spiral groove 402 of the guide rod 2. Its vertical displacement is converted into lateral extrusion force on the groove wall through the inclined structure of the spiral groove 402, pushing the guide rod 2 to rotate around the positioning rod 1, realizing stepless adjustment of the lighting angle. At the same time, the groove wall of the spiral groove 402 forms a lateral constraint on the slide rod 45, preventing the slide rod 45 from horizontally shifting due to vibration or off-center load, resulting in high stability.

[0035] The guide rod 2 has a large-diameter section at the top and a small-diameter section at the bottom. The outer diameter of the positioning rod 1 is equal to the outer diameter of the large-diameter section of the guide rod 2. The top of the positioning rod 1 is provided with a downwardly extending mounting groove, and the small-diameter section of the guide rod 2 is inserted into the mounting groove. The lighting lamp 3 is fixed on the large-diameter section of the guide rod 2. A spiral groove 402 is provided on the small-diameter section of the guide rod 2. The side wall of the mounting groove is provided with a vertically extending sliding groove 401. The first end of the sliding rod 45 passes through the sliding groove 401 and is then fitted into the spiral groove 402. The sliding rod 45 can slide up and down along the sliding groove 401. The outer wall of the large-diameter section of the guide rod 2 and the outer wall of the positioning rod 1 form an equal-diameter structure, so that the positioning rod 1... The outer wall of the positioning rod 1 covers the small-diameter section of the guide rod 2, improving the overall appearance consistency. Moreover, the outer wall of the positioning rod 1 also forms a dustproof protection structure for the spiral groove 402 on the small-diameter section of the guide rod 2, effectively preventing dust particles in the construction environment from entering the spiral groove 402. At the same time, the sliding groove 401 on the outer surface of the positioning rod 1 provides vertical guidance for the sliding rod 45. When the sliding rod 45 slides in the sliding groove 401, the side wall of the sliding groove 401 restricts the lateral degree of freedom of the sliding rod 45. Together with the inclined guiding effect of the spiral groove 402, they ensure the vertical movement of the sliding rod 45 and the spiral groove 402, significantly improving the control accuracy and operational stability of the rotation angle of the guide rod 2.

[0036] Specifically, the spiral groove 402 has a complete circle. The spiral groove 402 extends vertically from bottom to top and forms a complete circle around the axis. In the construction site, the power supply is generally provided to each lamp through the power supply line. The spiral groove 402 has a complete circle to ensure that the lighting lamp 3 rotates exactly one circle. This allows the lighting device to illuminate different construction areas around it according to actual needs. At the same time, due to the limiting effect of the spiral groove 402, only the lamp is allowed to complete a single circle of rotation, which effectively avoids the electrical safety hazards caused by the power supply line getting tangled due to excessive rotation.

[0037] Specifically, a support plate 41 is fixed at the top of the positioning rod 1, and the drive structure is mounted on the support plate 41, which provides a stable mounting base for the drive structure.

[0038] Specifically, a protective plate 51 is installed on the top of the guide rod 2. The protective plate 51 forms a protective structure for the lighting lamp 3, preventing the lighting lamp 3 from being damaged by falling objects when it is used at the construction site.

[0039] Specifically, a buffer assembly is also installed on the top of the protective plate 51, and an arc-shaped plate 55 is installed on the top of the buffer assembly. The buffer assembly is used to buffer the pressure on the arc-shaped plate 55. By absorbing the impact force of falling objects on the arc-shaped plate 55 and dispersing the pressure, the risk of damage to the lamps is further reduced and the service life of the device is extended.

[0040] Specifically, the buffer assembly includes several sleeves 52 and several sealing rods 53. Each sleeve 52 is fixed to the top of the protective plate 51, and each sealing rod 53 is slidably installed in each sleeve 52. The bottom of the arc-shaped plate 55 is fixedly connected to the top of each sealing rod 53. A compression spring 54 is installed inside the sleeve 52. One end of the compression spring 54 is fixedly connected to the bottom of the sleeve 52, and the other end of the compression spring 54 is fixedly connected to the bottom of the sealing rod 53. When the arc-shaped plate 55 is impacted by a falling object, the compression spring 54 is compressed and absorbs the impact energy, thereby converting the impact force on the arc-shaped plate 55 into the elastic potential energy of the spring, reducing the risk of direct damage to the protective plate 51 and the lighting lamp 3. At the same time, the elastic reset characteristic of the compression spring 54 allows the arc-shaped plate 55 to automatically return to its initial position after being subjected to force, ensuring the continuous protective capability of the buffer assembly. In addition, the sliding guide structure of the sleeves 52 and the sealing rods 53 improves the stability of the buffer action, avoids jamming caused by off-center loading, and the overall structure is simple and easy to maintain.

[0041] Specifically, a flow groove 501 is provided inside the sealing rod 53. One end of the flow groove 501 is connected to the outside, and the other end of the flow groove 501 is connected to the inner cavity of the sleeve 52. When the buffer assembly is compressed by impact, the sealing rod 53 squeezes the air in the sleeve 52 downward. Since one end of the flow groove 501 is connected to the outside, the air in the sleeve 52 is discharged outward through the flow groove 501. The narrow flow groove 501 generates an air resistance effect. When the air is discharged, a dynamic damping effect is formed. At the same time, the compression spring 54 is compressed and generates a reaction force, which plays a buffering role against the impact force of the falling object, further improving the buffering effect of the buffer assembly.

[0042] Specifically, the flow channel 501 is L-shaped.

[0043] In other embodiments, the drive structure is a telescopic cylinder, and the output shaft of the telescopic cylinder is fixedly connected to the slide rod 45.

[0044] The working process of this utility model is as follows: the small-diameter section of the guide rod 2 is inserted into the positioning rod 1, and the outer diameter of the positioning rod 1 is consistent with the outer diameter of the large-diameter section of the guide rod 2, so that the outer wall of the positioning rod 1 covers the small-diameter section of the guide rod 2, forming a dustproof and protective structure of the spiral groove 402; when it is necessary to adjust the light emission angle of the lighting lamp 3, the motor 42 in the drive structure is started, the motor 42 drives the vertically arranged lead screw 43 to rotate, and the slider 44 is connected to the lead screw 43 through a threaded engagement, so that when the lead screw 43 rotates, it moves up and down along the lead screw 43, and the slide rod 45 fixed on the slider 44 moves up and down synchronously. One end of the slide rod 45 passes through the slide groove 401 on the positioning rod 1 and is inserted into the spiral groove 401 provided on the outer surface of the small-diameter section of the guide rod 2. Within 2, as the slide rod 45 moves with the slider 44, the groove 401 guides the slide rod 45. During the up-and-down movement, the slide rod 45 presses against the wall of the spiral groove 402, pushing the guide rod 2 to rotate horizontally around the positioning rod 1. At the same time, the wall of the spiral groove 402 also forms a lateral constraint on the slide rod 45, preventing it from undergoing radial displacement due to vibration or off-center load. The horizontal rotation of the guide rod 2 around the positioning rod 1 enables stepless adjustment of the light output direction of the lighting lamp 3. Each lighting device can illuminate different construction areas around it according to actual needs. When the drive structure stops running, the mechanical self-locking effect formed between the slide rod 45 and the spiral groove 402 can stabilize the rotation angle of the guide rod 2, ensuring that the lighting direction remains unchanged, thus improving the stability and reliability of the device.

[0045] Furthermore, when a falling object impacts the curved plate 55, the compression spring 54 is compressed to absorb the impact energy. At the same time, the air inside the sleeve 52 is discharged outward through the L-shaped flow groove 501. The narrow flow groove 501 generates an air resistance effect, and the air discharge forms a dynamic damping effect, further enhancing the buffering effect of the buffer assembly. After the impact ends, the compression spring 54 releases its elastic potential energy, causing the curved plate 55 to automatically reset, ensuring that the buffer assembly can continue to play a protective role, improving the safety of the lighting device in complex construction environments, and extending the service life of the equipment.

[0046] In summary, this utility model provides a lighting device that employs a combination structure of a vertically arranged positioning rod and a horizontally rotating guide rod. The lighting lamp is mounted on the guide rod, and the rotation of the guide rod adjusts the light emission angle of the lamp. Each lighting device can illuminate different construction areas around it according to actual needs. Compared to the existing method of arranging multiple lighting devices at intervals to illuminate construction areas in different directions, this significantly reduces the number of lighting devices and the amount of construction space occupied, thus lowering construction costs. Furthermore, by setting an upward spiral groove on the guide rod and a driving structure on the positioning rod, a sliding rod connected to the driving end of the driving structure is inserted into the spiral groove. When the driving structure drives the sliding rod to move up and down, the sliding rod presses against the groove wall of the spiral groove, converting the vertical movement of the sliding rod into the horizontal rotation of the guide rod, thereby achieving stepless adjustment of the lighting direction. Moreover, when the driving structure stops, the sliding rod is fixed in the spiral groove, forming a self-locking structure, ensuring the stability of the guide rod angle and preventing displacement due to vibration or external forces, further reducing the cost and maintenance requirements of the lighting device.

[0047] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
