Description

Technical Field

[0001] The utility model relates to the technical field of LED floodlights, in particular to a modular LED floodlight. Background Art

[0002] Modular LED floodlights are a special type of LED lighting equipment. Their design features modular construction, which means that key components such as LED light sources, driver power supplies, and cooling systems are designed and packaged in the form of independent modules. This design not only allows each module to work independently of each other, but also allows users to flexibly select and combine different modules according to actual needs to achieve different lighting effects and power requirements.

[0003] Existing modular LED floodlights generally have simple adjustment mechanisms and are cumbersome to operate. During use, users often struggle to accurately and synchronously adjust the angle of each LED floodlight module. This undoubtedly increases the difficulty and time required to operate the lighting system, reduces the practicality of the LED floodlight, and fails to meet market demand. Therefore, we propose a modular LED floodlight. Utility Model Content

[0004] The purpose of the present utility model is to provide a modular LED floodlight to solve the problem raised in the above background technology that the adjustment mechanism of the existing modular LED floodlights is generally relatively simple and cumbersome to operate. When in use, it is often difficult for users to achieve accurate and synchronous angle adjustment of each LED floodlight module, which undoubtedly increases the operation difficulty and debugging time of the lighting system, reduces the practicality of the LED floodlight, and cannot meet the market demand.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a modular LED floodlight, comprising a support, wherein four floodlight bodies are provided at the upper end of the support, a first rotating rod is fixedly connected to the center of one side of the floodlight body, a transmission cavity is opened on one side of the support, and a second rotating rod is fixedly connected to the center of the other side of the four floodlight bodies, a rack is provided at the rear end position of one side in the transmission cavity, four gears are meshed on the front surface of the rack, a screw rod is provided on the other side of the transmission cavity, a disc is provided on one side of the top of the support, an adjusting button is fixedly installed on the top of the disc, a nut block is threadedly connected to the center position of the screw rod surface, a plurality of positioning grooves are opened on the surface of the disc, the upper end of the support is fixedly connected to a connecting frame corresponding to one side of the disc, a positioning pin is provided at the lower end of the connecting frame, a spring is sleeved on one side of the surface of the positioning pin, and one end of the positioning pin is fixedly connected to a pull rod.

[0006] Compared with the prior art, the beneficial effects of the present invention are:

[0007] The modular LED floodlight cabinet is designed with a second rotating rod, gear, rack, lead screw, nut block and adjusting knob. When the user turns the adjusting knob, the rack is driven to move up and down through the threaded transmission of the lead screw and the nut block. Since the rack is meshed with the four gears, the four gears simultaneously drive the four floodlight bodies to rotate as the rack moves up and down, thereby facilitating the adjustment of the illumination angles of the four floodlight bodies, enhancing the flexibility and accuracy of the lighting. The adjustment process is fast and convenient. The design of the disc, positioning slot, connecting frame, spring, positioning pin and pull rod allows the user to easily release the locking state of the positioning pin by lightly pulling the pull rod, and then drive the disc to the desired angle through the adjusting knob. After releasing the pull rod, the positioning pin will automatically spring into the nearest positioning slot under the action of the spring, achieving fast and accurate locking, ensuring that the adjusted angle is firmly locked, avoiding angle deviation caused by external force interference, and thus ensuring the stability and consistency of the lighting effect.

[0014] See also Figure 1-4The utility model provides a technical solution: a modular LED floodlight, comprising a support 1, four floodlight bodies 2 are provided on the upper end of the support 1, and a first rotating rod 3 is fixedly connected to the center of one side of the floodlight body 2. A transmission cavity 4 is opened on one side of the support 1, and the centers of the other sides of the four floodlight bodies 2 are fixedly connected to a second rotating rod 5. A rack 7 is provided at the rear end position of one side in the transmission cavity 4, and four gears 6 are meshed on the front surface of the rack 7. A screw rod 8 is provided on the other side of the transmission cavity 4. A disc 13 is provided on one side of the top of the support 1, and an adjusting button 14 is fixedly installed on the top of the disc 13. A nut block 9 is threadedly connected to the center position of the surface of the screw rod 8, and a plurality of positioning grooves 15 are opened on the surface of the disc 13. The upper end of the support 1 is fixedly connected to a connecting frame 16 corresponding to one side of the disc 13, and a positioning pin 18 is provided at the lower end of the connecting frame 16. A spring 17 is sleeved on one side of the surface of the positioning pin 18, and a pull rod 19 is fixedly connected to one end of the positioning pin 18.

[0015] The four floodlight bodies 2 are arranged vertically, and one end of the four first rotating rods 3 is movably connected to the four bearings fixedly installed on the inner side of the support 1. One end of the four second rotating rods 5 passes through the interior of the transmission cavity 4 and is fixedly connected to the center of one side of the four gears 6, thereby ensuring the stability of the floodlight body 2 during angle adjustment.

[0016] The lower end of the screw rod 8 is movably connected to a bearing fixedly installed on one side of the bottom of the transmission chamber 4. The upper end of the screw rod 8 passes through the outside of the support 1 and is fixedly connected to the center of the bottom of the disc 13. The adjusting button 14 can synchronously drive the disc 13 and the screw rod 8 to rotate.

[0017] The adjusting button 14 is a columnar structure, and the outer wall of the adjusting button 14 is provided with anti-skid vertical grooves to prevent the user from slipping when turning the adjusting button 14.

[0018] The top and bottom of one side of the nut block 9 are fixedly connected to the connecting blocks 10, and one end of the two connecting blocks 10 is fixedly connected to one side of the rack 7. The nut block 9 drives the rack 7 to move vertically through the connecting blocks 10.

[0019] A guide groove 11 is provided on the inner wall of the transmission chamber 4 corresponding to the rear end of the rack 7. Guide blocks 12 are fixedly connected to the top and bottom of the rear surface of the rack 7. The rear ends of the two guide blocks 12 pass through the interior of the guide groove 11 and are slidably connected to the inner wall of the guide groove 11, ensuring the stability and verticality of the rack 7 during movement.

[0020] The right end of the positioning pin 18 passes through the interior of the connecting frame 16 and the positioning groove 15 in sequence and contacts the inner wall of the positioning groove 15. One end of the spring 17 is fixedly connected to the inner side of the connecting frame 16, and the other end of the spring 17 is fixedly connected to one side of the positioning pin 18. One end of the pull rod 19 passes through the outside of the connecting frame 16.

[0021] Working principle: When using the modular LED floodlight for angle adjustment, first, the user needs to pull the pull rod 19. This action will overcome the elastic force of the spring 17 and pull the positioning pin 18 out of the positioning slot 15 on the connecting frame 16 and the disc 13, thereby releasing the current locked state of the disc 13. Then, the user can freely turn the adjusting knob 14. As the adjusting knob 14 rotates, the disc 13 and the screw rod 8 fixed to it are synchronously driven to rotate together. The rotation of the screw rod 8 then produces relative motion with the nut block 9 through the thread on its surface, so that the nut block 9 moves along the axial direction of the screw rod 8. The movement of the nut block 9 drives the rack 7 to move vertically in the transmission cavity 4 through the connecting block 10 fixedly connected at its top and bottom. The vertical movement of the rack 7 is transmitted to the four gears 6 meshing with its front surface. Since one end of the four second rotating rods 5 is fixedly connected to the center of one side of the four gears 6, the rotation of the gear 6 will drive the second rotating rods 5 and the floodlight body 2 fixed thereto to perform synchronous angle adjustment. At the same time, in order to ensure the stability and verticality of the rack 7 during movement, a guide groove 11 is opened on the inner wall of the transmission cavity 4 corresponding to the rear end of the rack 7. The guide blocks 12 fixedly connected to the top and bottom of the rear surface of the rack 7 slide in the guide groove 11. When the user completes the required angle adjustment, he only needs to release the pull rod 19. At this time, the elastic force of the spring 17 will push the positioning pin 18 to re-enter the positioning groove 15 on the connecting frame 16 and the disc 13, so as to realize the locking of the adjusted angle of the disc 13 and the floodlight body 2. In this way, the entire modular LED floodlight can provide stable lighting at the angle set by the user.

[0022] In summary: the modular LED floodlight cabinet, through the design of the second rotating rod 5, gear 6, rack 7, screw 8, nut block 9 and adjusting button 14, when the user turns the adjusting button 14, the screw 8 and the nut block 9 are threadedly driven to drive the rack 7 to move up and down. Since the rack 7 is meshed with the four gears 6, the four gears 6 simultaneously drive the four floodlight bodies 2 to rotate as the rack 7 moves up and down, thereby facilitating the adjustment of the illumination angles of the four floodlight bodies 2, enhancing the flexibility and accuracy of the lighting, and the adjustment process is fast and convenient. The disc 13, positioning The design of the slot 15, connecting frame 16, spring 17, positioning pin 18 and pull rod 19 is such that when the user needs to change the illumination angle of the floodlight, he only needs to gently pull the pull rod 19 to easily release the locked state of the positioning pin 18, and then drive the disk 13 to the desired angle through the adjustment button 14. After releasing the pull rod 19, the positioning pin 18 will automatically bounce into the nearest positioning slot 15 under the action of the spring 17, realizing fast and accurate locking, ensuring that the adjusted angle is firmly locked, avoiding angle deviation due to external interference, and thus ensuring the stability and consistency of the lighting effect.
