Description

Technical Field

[0001] The utility model relates to the technical field of LED floodlights, in particular to an LED floodlight with a combined fixing piece. Background Art

[0002] LED floodlight is a high-efficiency lighting device that uses LED (light-emitting diode) as a light source. It has the advantages of energy saving, high light efficiency, long life, bright colors, strong shock resistance, etc. The device converts electrical energy into light energy to generate high-brightness light, and can be aimed in any direction for projection. LED floodlights are mainly used in architectural lighting, landscape lighting, billboard lighting, commercial space lighting and other fields, and can provide high-quality lighting effects for indoor and outdoor environments.

[0003] Although existing LED floodlights have advantages in lighting efficiency and energy saving, they have obvious shortcomings in the convenience of maintenance after installation. Once these lamps need to be repaired or replaced after installation, the disassembly process often becomes extremely cumbersome and time-consuming due to their complex installation structure and fastening methods. This not only increases the difficulty of maintenance work, but may also lead to an increase in maintenance costs, because improper disassembly may also damage the lamp itself or other related parts. Therefore, we propose an LED floodlight with a combined fixing. Utility Model Content

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0007] The LED floodlight with combined fixings is designed with a bidirectional screw rod, a slot, a plug plate, a nut block, a card plate, a slot, a rotary rod, a first gear, a second gear and a knob. The user only needs to simply turn the knob to drive the rotary rod and the second gear connected thereto to rotate, thereby driving the first gear and the bidirectional screw rod to rotate. This linkage mechanism causes the two nut blocks to move toward or oppositely on the bidirectional screw rod, thereby driving the card plate to snap into or out of the slot, thereby achieving stable installation or easy disassembly of the floodlight body. This design not only significantly improves the convenience of maintenance work and reduces the difficulty of operation, but also ensures the stability and reliability of the floodlight in long-term use, bringing users more efficiency and flexibility. The lighting solution, the design of connecting rod, disc, positioning hole, hollow block, spring, positioning rod, connector and push button allows the user to easily rotate the disc according to specific lighting needs, and drive the floodlight body to adjust the angle through the connecting rod until the ideal lighting effect is achieved. Afterwards, the user only needs to simply release the push button to drive the connecting part to drive the positioning rod to accurately snap into or out of the positioning hole in the hollow block under the elastic force of the spring, thereby firmly locking the current irradiation angle of the floodlight body.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0015] See also Figure 1-5The utility model provides a technical solution: an LED floodlight with a combined fixing, comprising a base 1, a bracket 2 is arranged on the upper end of the base 1, a floodlight body 3 is arranged on the upper end of the bracket 2, a bidirectional screw rod 4 is arranged in the center of the base 1, slots 5 are provided at both sides of the top of the base 1, plug-in boards 6 are inserted into the inner walls of the two slots 5, two card slots 9 are provided on the opposite sides of the two plug-in boards 6, nut blocks 7 are threadedly connected to the two sides of the surface of the bidirectional screw rod 4, the top and bottom of the opposite side of the two nut blocks 7 are fixedly connected with card plates 8, a rotating rod 10 is movably installed at the center of the top of the base 1, and the surface of the bidirectional screw rod 4 A first gear 11 is fixedly installed at the center position, and a second gear 12 is meshedly connected to the top of the first gear 11. A knob 13 is provided at the center of the lower end of the floodlight body 3, and connecting rods 14 are fixedly connected to the centers of both sides of the floodlight body 3. A disk 15 is provided at the top of one side of the bracket 2, and a positioning hole 16 is provided on the outer wall of the disk 15. A hollow block 17 is fixedly installed on the outside of the bracket 2 corresponding to the lower end of the disk 15, and a spring 18 is fixedly connected to the bottom of the hollow block 17, and a positioning rod 19 is fixedly connected to the upper end of the spring 18. A push button 21 is provided on one side of the hollow block 17, and a connecting piece 20 is fixedly connected to the bottom of one side of the positioning rod 19.

[0016] The two ends of the bidirectional screw rod 4 are movably connected to the bearings fixedly installed in the center of both sides of the base 1, ensuring that the bidirectional screw rod 4 can rotate steadily and smoothly in the base 1, providing a solid foundation for the subsequent movement of the nut block 7 and the clamping operation of the clamping plate 8, thereby realizing the stable installation and disassembly of the floodlight body 3.

[0017] The tops of the two plug plates 6 respectively penetrate through the outside of the two slots 5 and are fixedly connected to the two sides of the bottom of the bracket 2. The opposite sides of the four clamping plates 8 arranged on both sides respectively penetrate through the inside of the two slots 5 and are clamped with the inner walls of the four clamping slots 9, ensuring a firm connection between the bracket 2 and the base 1. At the same time, the clamping connection between the clamping plates 8 and the clamping slots 9 further enhances the installation stability of the floodlight body 3 to prevent it from shaking or falling off during operation.

[0018] The lower end of the rotating rod 10 passes through the interior of the base 1 and is fixedly connected to the center of the top of the second gear 12. A groove is opened in the center of the bottom of the bracket 2. The top of the rotating rod 10 passes through the outside of the groove and is fixedly connected to the center of the bottom of the knob 13. The user can easily drive the rotating rod 10 and the second gear 12 to rotate by rotating the knob 13, thereby realizing the rotation of the bidirectional screw rod 4, which provides a convenient operation method for the installation and disassembly of the floodlight body 3.

[0019] One end of the connecting rod 14 arranged on the right side passes through the outside of the bracket 2 and is movably connected to the bearing fixedly installed on the top of the other side of the outer wall of the bracket 2. One end of the connecting rod 14 arranged on the left side passes through the outside of the bracket 2 and is fixedly connected to the center of one side of the disc 15, so that the disc 15 can rotate smoothly on the bracket 2 through the connecting rod 14, providing a reliable support and rotation mechanism for adjusting the illumination angle of the floodlight body 3.

[0020] There are several positioning holes 16, which are equidistantly arranged. The upper end of the positioning rod 19 passes through the interior of the hollow block 17 and the positioning hole 16 in sequence and is clamped with the inner wall of the positioning hole 16. A vertical groove is opened at the bottom of one side of the hollow block 17. One end of the connecting piece 20 passes through the outside of the vertical groove and is fixedly connected to the center of one side of the push button 21. The user can easily control the clamping and disengagement of the positioning rod 19 in the positioning hole 16 by pressing or releasing the push button 21, thereby realizing accurate positioning and firm locking of the illumination angle of the floodlight body 3 to prevent angle changes due to accidental collisions.

[0021] The bottom of both sides of the base 1 are fixedly connected with connecting plates, and the top of the connecting plates is provided with mounting holes, which provide users with a convenient installation interface, so that the floodlight can be firmly installed on the wall or other fixed structures, ensuring its stability and safety during work.

[0022] Working principle: First, the user firmly installs the base 1 of the LED floodlight with combined fixings on the wall or other fixed structures through the connecting plates and mounting holes fixedly connected at the bottom of both sides. Then, insert the two sides of the bottom of the bracket 2 into the slots 5 at the top of the base 1 through the plug-in plate 6, and ensure that the slots 9 on the plug-in plate 6 correspond to the card plates 8 inside the base 1. At this time, the user rotates the knob 13, and the knob 13 drives the second gear 12 to rotate through the rotating rod 10, and then the first gear 11 engaged with the second gear 12 drives the bidirectional screw 4 to rotate. The rotation of the bidirectional screw 4 causes the two nut blocks 7 to move toward the center along its surface, thereby pushing the card plate 8 to be inserted into the slots 9 on the plug-in plate 6, thereby realizing a stable connection between the bracket 2 and the base 1, and also completing the installation of the floodlight body 3. After the installation is completed, the user can adjust the irradiation angle of the floodlight body 3 as needed. At this time, the user only needs to hold the disc 15 and rotate it gently. The disc 15 is connected to the bracket 2 through the connecting rod 14 on the left, and the connecting rod 14 on the right rotates smoothly on the bracket 2 through the bearing, providing reliable support for the rotation of the disc 15 and the floodlight body 3. After adjusting to the desired angle, the user only needs to press the push button 21. The push button 21 pushes the positioning rod 19 through the connecting piece 20 to overcome the elastic force of the spring 18, so that the positioning rod 19 is disengaged from the current positioning hole 16. Then, the user fine-tunes the disc 15 to the precise position and releases the push button 21. The positioning rod 19 is automatically snapped into the new positioning hole 16 under the action of the spring 18, thereby realizing the precise positioning and firm locking of the irradiation angle of the floodlight body 3.

[0023] In summary: the LED floodlight with combined fixings, through the design of the bidirectional screw rod 4, slot 5, plug plate 6, nut block 7, card plate 8, card slot 9, rotary rod 10, first gear 11, second gear 12 and knob 13, the user only needs to simply turn the knob 13 to drive the rotary rod 10 and the second gear 12 connected thereto to rotate, thereby driving the first gear 11 and the bidirectional screw rod 4 to rotate. This linkage mechanism prompts the two nut blocks 7 to move toward or oppositely on the bidirectional screw rod 4, thereby driving the card plate 8 to snap into or out of the card slot 9, thereby achieving stable installation or easy disassembly of the floodlight body 3. This design not only significantly improves the convenience of maintenance work and reduces the difficulty of operation, but also ensures the stability and reliability of the floodlight in long-term use, bringing users more efficient and flexible. The lighting solution, the design of the connecting rod 14, the disc 15, the positioning hole 16, the hollow block 17, the spring 18, the positioning rod 19, the connecting piece 20 and the push button 21, allows the user to easily rotate the disc 15 according to specific lighting needs, and drive the floodlight body 3 to adjust the angle through the connecting rod 14 until the ideal lighting effect is achieved. Afterwards, the user only needs to simply release the push button 21 to drive the connecting piece 20 to drive the positioning rod 19 under the elastic force of the spring 18 to accurately snap into or disengage from the positioning hole 16 in the hollow block 17, thereby firmly locking the current irradiation angle of the floodlight body 3. This design not only ensures the angle stability of the floodlight body 3 after adjustment, effectively avoids angle deviation caused by accidental collision or wind and other factors, but also greatly improves the convenience and safety of user operation.
