Description

Technical Field

[0001] This invention relates to the field of floodlight technology, and in particular to a combined floodlight and its usage method. Background Technology

[0002] Floodlights are lighting fixtures that provide illumination to a surface higher than the surrounding environment, and are generally used for outdoor lighting. They can be aimed in any direction and have a structure unaffected by weather conditions. They are mainly used for large-area work sites, building outlines, stadiums, overpasses, memorial halls, parks, and flower beds.

[0003] However, existing floodlights still have some shortcomings in use:

[0004] 1. Floodlights need to be connected to corresponding lamp holders for use. However, floodlights and lamp holders need to be separated during manufacturing and transportation before being assembled. In the existing technology, the assembly of floodlights and lamp holders is time-consuming and labor-intensive, which affects the assembly efficiency of floodlights.

[0005] 2. Lamp holders are often installed to external mounting brackets using bolts. However, over time, dust tends to accumulate in the grooves of the bolts, making it difficult to remove the bolts later, which in turn affects the removal and replacement of the lamp holder.

[0006] 3. When it is necessary to project corresponding lights according to the external conditions, the lights cannot be easily replaced, and the entire floodlight must be replaced, which increases the cost.

[0007] To address the aforementioned problems, this invention proposes a combined floodlight and its usage method. Summary of the Invention

[0008] The purpose of this invention is to solve the shortcomings of existing floodlights, such as the inability to easily replace the lights, the time and effort required to assemble the floodlights and lamp holders, and the difficulty in disassembling the lamp holder bolts later. The invention proposes a combined floodlight and its usage method.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A combined floodlight includes a base, with support arms welded to both sides of the top of the base, a floodlight disposed between the two support arms, and insert rods slidably passing through the two support arms, the two insert rods being used to clamp and fix the floodlight, and a replaceable filter being disposed inside the floodlight.

[0011] It also includes a mounting groove provided in the base, wherein the mounting groove is provided with a plurality of cross-slot bolts, and the cross-slot bolts are used to fix the base to the mounting bracket;

[0012] It also includes an auxiliary plate, which is positioned above the base to support the floodlight;

[0013] Two sets of clamping structures are respectively set on two plug rods for clamping and fixing the floodlight;

[0014] The support structure, located inside the auxiliary plate, is used to support the floodlight to be clamped, and the support structure can also protect the cross-slot bolts.

[0015] The transmission structure is located on one side of one of the support arms, and the clamping structure can release the support structure from the floodlight through the transmission structure.

[0016] In one possible design, the clamping structure includes a rotating disk that rotates on the end of the insertion rod away from the floodlight. The support arm has an internal threaded groove on the side away from the floodlight. A cylinder is fixed to one side of the rotating disk, and the outer wall of the cylinder is threaded. The cylinder is threadedly connected to the internal threaded groove. A slot is provided on one side of the floodlight, and multiple pin holes are arranged in a ring on the same side. The slot engages with the insertion rod. A damping bearing is fixedly fitted onto the outer wall of the insertion rod. The outer wall of the support is fitted with a mounting plate, which mates with a pin hole. The cylinder drives the insertion rod to move, and the insertion rod and pin can be inserted into the slot and pin hole to hold the floodlight. Rotating the rotating disk drives the cylinder to rotate. The cylinder is threadedly connected to the internal thread groove. The rotating disk, insertion rod, and mounting plate move towards the floodlight until the insertion rod and pin are initially inserted into the slot and pin hole. At this time, the floodlight is initially fixed. When the pin contacts the inner wall of one side of the pin hole, there is a gap between the insertion rod and the inner wall of one side of the slot.

[0017] In one possible design, the support structure includes multiple rubber rods rotating within an auxiliary plate. Neodymium magnets are fixedly embedded on both the top and bottom sides of the multiple rubber rods. Multiple grooves are provided on both top sides of the auxiliary plate to accommodate the neodymium magnets. Each of the two support arms has a sliding groove, and the auxiliary plate is slidably positioned within the two sliding grooves. Multiple iron blocks are fixed to the top inner walls of each of the two sliding grooves, and a magnetic attraction is generated between the iron blocks and the neodymium magnets to attract the auxiliary plate and support the floodlight. One end of each of the multiple rubber rods extends rotatably to one side of the auxiliary plate and is fixed with a gear. The auxiliary plate is pushed upwards until the iron blocks engage with the neodymium magnets. The magnetic attraction between the neodymium magnets and the iron blocks firmly attracts the auxiliary plate to the top inner wall of the sliding groove. The floodlight is then placed on the auxiliary plate to support it, facilitating subsequent clamping and fixing of the floodlight with pins and rods.

[0018] In one possible design, the support structure further includes a relief groove at the bottom of the auxiliary plate for storing and protecting the Phillips head bolts. Multiple circular grooves are provided on both sides of the bottom of the auxiliary plate, and these grooves correspond to the neodymium magnets below the rubber rod. Multiple iron blocks are fixed to both sides of the top of the base, and these iron blocks engage with the circular grooves and generate magnetic attraction with the neodymium magnets. The engagement of the iron blocks and the neodymium magnets firmly attaches the auxiliary plate to the base. When the auxiliary plate falls onto the base, the Phillips head bolts extend into the relief grooves, protecting them. The iron blocks are inserted into the circular grooves, and the neodymium magnets below the rubber rods generate magnetic attraction, firmly attaching the auxiliary plate to the base. This prevents dust accumulation in the Phillips head bolts and facilitates loosening the bolts later.

[0019] In one possible design, the transmission structure includes a base fixed to one side of one of the support arms. A Z-shaped rod slides through the base, and a first trapezoidal block and a second trapezoidal block are fixed to the top and bottom of the Z-shaped rod, respectively. The inclined surface of the first trapezoidal block engages with a corresponding rotating disk. A movable frame is slidably connected to one side of the auxiliary plate. A rack is fixed to the bottom inner wall of the movable frame, and the rack meshes with a gear. The inclined surface of the second trapezoidal block engages with the movable frame to drive the movable frame to move the rack. As the rotating disk continues to rotate, the insert rod and pin further clamp and fix the floodlight. One side of the rotating disk engages with the inclined surface of the first trapezoidal block, which can push the first trapezoidal block, the Z-shaped rod, and the second trapezoidal block downwards. The inclined surface of the second trapezoidal block engages with the moving frame, which pushes the moving frame to the left. The moving frame drives the rack to move, and the rack drives the rubber rod to rotate through the gear. At this time, the rubber rod rotates 90°, and the neodymium magnet above the rubber rod is just misaligned with the iron block, releasing the magnetic attraction between the neodymium magnet and the iron block, and releasing the auxiliary plate from supporting the floodlight.

[0020] In one possible design, a sliding rod is fixed to the bottom of the first trapezoidal block, and the bottom end of the sliding rod slides through the base. The sliding rod is used to make the first trapezoidal block rise and fall smoothly. A second spring is sleeved on the outer wall of the sliding rod and fixedly connected to the bottom of the first trapezoidal block. The bottom end of the second spring is fixedly connected to the top of the base. The second spring is used to reset the first trapezoidal block.

[0021] In one possible design, a fixing plate is fixed to one side of the auxiliary plate, and a first spring is fixed to one side of the fixing plate. A pressure plate is fixed to the end of the first spring away from the fixing plate, and the pressure plate is fixed to the top inner wall of the movable frame. The cooperation between the first spring and the pressure plate is used to reset the movable frame.

[0022] In one possible design, a placement groove is provided on one side of the floodlight, and a filter is placed in the placement groove. The filter is used to change the color of the light emitted by the floodlight. A rotating plate is rotatably connected to one side of the floodlight, and the rotating plate is used to limit the position of the filter. A second magnet strip is fixedly embedded on one side of the floodlight, and a first magnet strip is fixedly embedded on one side of the rotating plate. The magnetic attraction between the first magnet strip and the second magnet strip is used to position the rotating plate.

[0023] In one possible design, L-shaped limiting plates are fixed to the opposite sides of the two support arms, and these L-shaped limiting plates are used to limit the rotation of the rotating disk. A red marking strip is fixedly embedded on the top of the L-shaped limiting plate to determine the distance the rotating disk moves. The L-shaped limiting plate is made of transparent acrylic material to allow clear observation of the distance the rotating disk moves. When the rotating disk drives the cylinder to rotate, the distance the rotating disk moves can be observed through the transparent acrylic material of the L-shaped limiting plate. When the rotating disk moves to the position of the red marking strip, the insert rod and pin are inserted into the slot and pin hole, initially clamping the floodlight. At this time, the rotating disk and the first trapezoidal block are in initial contact. Then, through the cooperation of the L-shaped limiting plate and the red marking strip, the supporting effect of the auxiliary plate can be automatically released after the floodlight is clamped and fixed.

[0024] This application discloses a method for using a combined floodlight, comprising the following steps:

[0025] S1. During the assembly stage, the base is fixed to the frame with cross-slot bolts. Then, the auxiliary plate is moved up and fixed to the top of the slide using the magnetic attraction between the neodymium magnet and the iron block. The floodlight is placed on the auxiliary plate in preparation for subsequent fixing.

[0026] S2. Rotating the rotating disc drives the cylinder to rotate and advance along the internal thread groove until the plug and pin are initially inserted into the slot and pin hole of the floodlight, thus initially fixing the floodlight.

[0027] S3. Continue to rotate the rotating disk to increase the clamping force of the pin, and at the same time trigger the linkage mechanism to push the first trapezoidal block and the second trapezoidal block, drive the rack to move, and transmit the force through the gear to make the rubber rod rotate 90°, release the neodymium magnet from the iron block, and the auxiliary plate loses its support, making it easier to adjust the angle of the floodlight.

[0028] S4. When the auxiliary plate descends naturally, the first spring reset mechanism drives the rack and moving frame to return to their original positions, and the rubber rod rotates in the opposite direction to reset. When the auxiliary plate falls to the base, the cross-slot bolts automatically enter the clearance slot for protection, and at the same time, the neodymium magnet under the rubber rod attracts the iron column block, stabilizing the auxiliary plate on the base, protecting the cross-slot bolts from dust, and facilitating future disassembly.

[0029] S5. When changing the lighting color, the filter can be replaced simply by rotating the rotating plate, which is convenient to operate. The position of the rotating plate can be observed through the transparent L-shaped limit plate. When it moves to the red mark, the floodlight is fixed and the auxiliary plate support is automatically released, achieving precise operation.

[0030] Beneficial effects:

[0031] In this invention, the support arm has an internal threaded groove on the side away from the floodlight, a cylinder is fixed on one side of the rotating disk, a damping bearing is fixedly sleeved on the outer wall of the insertion rod, and an mounting plate is sleeved on the outer wall of the damping bearing. The mounting plate cooperates with the pin hole. When the rotating disk is rotated, the rotating disk drives the cylinder to rotate. The cylinder is threadedly connected to the internal threaded groove. The rotating disk, insertion rod, and mounting plate move towards the floodlight until the insertion rod and pin are initially inserted into the slot and pin hole, which can easily complete the fixing of the floodlight.

[0032] In this invention, neodymium magnets are fixedly embedded on both sides of the top and bottom of the multiple rubber rods, and multiple grooves are provided on both sides of the top of the auxiliary plate. Multiple iron blocks are fixed on the inner walls of the top of the two slides. When the auxiliary plate is pushed up, the magnetic attraction between the neodymium magnets and the iron blocks firmly attracts the auxiliary plate to the inner wall of the top of the slide. Then, the floodlight is placed on the auxiliary plate to support the auxiliary plate, which facilitates the subsequent clamping and fixing of the floodlight by the pins and rods.

[0033] In this invention, the support structure also includes a clearance groove at the bottom of the auxiliary plate. The bottom sides of the auxiliary plate are provided with multiple circular grooves, and the top sides of the base are fixed with multiple iron pillars. When the auxiliary plate falls and lands on the base, the cross-slot bolts extend into the clearance grooves to protect the cross-slot bolts. The iron pillars are inserted into the circular grooves, and the neodymium magnets below the rubber rods generate magnetic attraction to the iron pillars, which can firmly attract the auxiliary plate to the base, preventing dust from accumulating in the cross slots of the cross-slot bolts and making it easier to loosen the cross-slot bolts later.

[0034] In this invention, a rack is provided on one side of the floodlight, a filter is disposed inside the rack, a rotating plate is rotatably connected to one side of the floodlight, a second magnet strip is fixedly embedded on one side of the floodlight, and a first magnet strip is fixedly embedded on one side of the rotating plate; the filter is used to change the color of the light emitted by the floodlight, and the magnetic attraction between the first and second magnet strips is used to position the rotating plate, allowing the light emitted by the floodlight to be changed as needed.

[0035] In this invention, the base and floodlight can be easily clamped and fixed by the cooperation of the auxiliary plate, the plug rod and the pin. In addition, after the fixing is completed, the auxiliary plate can automatically collect and protect the cross-slot bolts, avoid dust accumulation on the cross slots of the cross-slot bolts, and ensure that the cross-slot bolts can be turned to remove the installation of the base and the fixing frame later.

[0048] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0049] Example 1

[0050] Reference Figure 1 and Figure 2 A combined floodlight is used in the field of floodlights. The floodlight mainly includes a base 1, with support arms 2 welded to both sides of the top of the base 1. A floodlight 3 is set between the two support arms 2. The floodlight 3 has a replaceable filter 39. This design allows for adjustment of the color or effect of the projected light as needed.

[0051] Reference Figure 5 The base 1 has a mounting groove 22 inside, and multiple cross-slot bolts 23 are placed in the mounting groove 22. These bolts are used to firmly fix the base 1 to a fixed frame to ensure the stability of the floodlight.

[0052] Reference Figure 1 and Figure 5 Above the base 1, an auxiliary plate 17 is also provided. The purpose of this auxiliary plate is to provide a temporary support point for the floodlight 3 when installing or adjusting it.

[0053] Reference Figure 1 and Figure 3 In order to achieve a stable clamping of the floodlight 3, we designed two sets of clamping structures, which are respectively installed on two insert rods 6. The insert rods 6 can slide inside the support arm 2, and the floodlight 3 can be clamped and fixed through them.

[0054] Reference Figure 5The auxiliary plate 17 also has a support structure, which not only provides support for the floodlight 3 before clamping it, but also provides some protection for the cross-slot bolts 23 in the mounting slot 22.

[0055] Reference Figure 8 In addition, we have also set a transmission structure on one side of one of the support arms 2, which allows the clamping structure to release the support structure from the floodlight 3 when needed, thereby enabling easy installation and removal of the floodlight 3.

[0056] Reference Figure 1 , Figure 3 and Figure 4 Next, we will describe the clamping structure in detail: The clamping structure mainly includes a rotating disk 7, which is installed on the end of the plug rod 6 away from the floodlight 3. The support arm 2 is provided with an internal thread groove 9 on the side away from the floodlight 3. A cylinder 8 is fixed on one side of the rotating disk 7. The outer wall of the cylinder 8 is threaded and can be threaded to the internal thread groove 9.

[0057] Reference Figures 2-4 The floodlight 3 has a slot 4 and a number of pin holes 5 arranged in a ring on one side. The slot 4 is engaged with the plug rod 6. A damping bearing 10 is fixedly sleeved on the outer wall of the plug rod 6. A mounting plate 11 is sleeved on the outer wall of the damping bearing 10. This mounting plate 11 is matched with the pin holes 5.

[0058] When we need to clamp the floodlight 3, we only need to rotate the rotating disk 7. The rotating disk 7 will drive the cylinder 8 to rotate. Since the cylinder 8 is threadedly connected to the internal threaded groove 9, the rotating disk 7, the insert rod 6 and the mounting plate 11 will move together toward the floodlight 3 until the insert rod 6 and the pin 12 are initially inserted into the slot 4 and the pin hole 5. At this time, the floodlight 3 is initially fixed. It should be noted that when the pin 12 contacts the inner wall of one side of the pin hole 5, there will still be a certain gap between the insert rod 6 and the inner wall of one side of the slot 4.

[0059] Reference Figures 5-7 Regarding the design of the support structure: The support structure mainly includes multiple rubber rods 19 that rotate within the auxiliary plate 17. Neodymium magnets 20 are fixedly embedded on both sides of the top and bottom of these rubber rods 19. Multiple grooves 18 are provided on both sides of the top of the auxiliary plate 17. These grooves 18 are used to make way for the neodymium magnets 20.

[0060] Reference Figure 5Both support arms 2 are equipped with sliding grooves 15. The auxiliary plate 17 is slidably set in these two sliding grooves 15. Multiple iron blocks 16 are fixed on the top inner wall of the sliding groove 15. These iron blocks 16 and neodymium magnets 20 will generate magnetic attraction. When we push the auxiliary plate 17 to move upward, the iron blocks 16 will cooperate with the neodymium magnets 20, and the auxiliary plate 17 will be firmly attracted to the top inner wall of the sliding groove 15 by the magnetic attraction between them.

[0061] At this point, we can place the floodlight 3 on the auxiliary plate 17 for support. This design not only makes it easier for us to use the pin 12 and the rod 6 to clamp and fix the floodlight 3 later, but also ensures the stability and safety of the floodlight 3 during the clamping process.

[0062] Reference Figure 5 and Figure 6 In the support structure of the combined floodlight, a relief groove 26 is specially set at the bottom of the auxiliary plate 17. The design of this relief groove 26 is very ingenious. It can store and protect the cross-slot bolt 23. When the auxiliary plate 17 is in its working position, the cross-slot bolt 23 will be completely hidden in the relief groove 26, thereby avoiding the accumulation of dust and dirt, and making it easy to loosen the cross-slot bolt 23 during later maintenance.

[0063] Reference Figure 5 and Figure 6 Meanwhile, the bottom sides of the auxiliary plate 17 are provided with multiple circular grooves 25, which correspond to the neodymium magnets 20 below the rubber rod 19. On the top sides of the base 1, multiple iron pillars 24 are fixed. These iron pillars 24 are matched with the circular grooves 25, and they generate a strong magnetic attraction with the neodymium magnets 20. When the auxiliary plate 17 falls and lands on the base 1, the iron pillars 24 will insert into the circular grooves 25, and the neodymium magnets 20 below the rubber rod 19 will generate a magnetic attraction on the iron pillars 24, thereby firmly adhering the auxiliary plate 17 to the base 1.

[0064] Reference Figure 3 and Figure 8 Next, let's look at the design of the transmission structure. The transmission structure mainly includes a base 32 fixed to one side of one of the support arms 2. A Z-shaped rod 33 slides through the base 32. The top and bottom ends of the Z-shaped rod 33 are respectively fixed with a first trapezoidal block 34 and a second trapezoidal block 35. In particular, the inclined surface of the first trapezoidal block 34 is matched with the corresponding rotating disk 7.

[0065] Reference Figure 3 , Figure 8 and Figure 9On one side of the auxiliary plate 17, a movable frame 27 is slidably connected. A rack 28 is fixed on the bottom inner wall of the movable frame 27. The rack 28 meshes with the gear 21 at one end of the rubber rod 19. The inclined surface of the second trapezoidal block 35 is matched with the movable frame 27. It is used to drive the movable frame 27 to move the rack 28.

[0066] As the rotating disk 7 continues to rotate, the insertion rod 6 and the pin 12 will further clamp and fix the floodlight 3. At the same time, one side of the rotating disk 7 will cooperate with the inclined surface of the first trapezoidal block 34, thereby pushing the first trapezoidal block 34, the Z-shaped rod 33 and the second trapezoidal block 35 to move down as a whole. During this process, the inclined surface of the second trapezoidal block 35 will cooperate with the moving frame 27, pushing the moving frame 27 to move to the left. The movement of the moving frame 27 will drive the rack 28 to move together, and the rack 28 will drive the rubber rod 19 to rotate through the gear 21.

[0067] Reference Figure 5 and Figure 7 In particular, when the rubber rod 19 rotates 90°, the neodymium magnet 20 above the rubber rod 19 will be misaligned with the iron block 16, thereby releasing the magnetic attraction between the neodymium magnet 20 and the iron block 16. As a result, the support of the auxiliary plate 17 for the floodlight 3 will be released, allowing the floodlight 3 to be more securely clamped between the support arms 2.

[0068] Reference Figure 8 To ensure that the first trapezoidal block 34 can move smoothly up and down, a sliding rod 36 is fixed at the bottom of the first trapezoidal block 34. The bottom end of the sliding rod 36 slides through the base 32, providing a stable sliding track for the first trapezoidal block 34. At the same time, a second spring 37 is fitted on the outer wall of the sliding rod 36. The top end of the second spring 37 is fixedly connected to the bottom of the first trapezoidal block 34, while the bottom end is fixedly connected to the top of the base 32. In this way, when the first trapezoidal block 34 is moved by external force, the second spring 37 can play a role in buffering and resetting, so that the first trapezoidal block 34 can smoothly return to its initial position.

[0069] Reference Figure 6 , Figure 8 and Figure 9 In the structure of the combined floodlight, a fixing plate 31 is fixedly connected to one side of the auxiliary plate 17. The fixing plate 31 is designed to provide a stable support point for installing and fixing the first spring 30. One end of the first spring 30 is tightly fixed to the fixing plate 31, while its other end is fixedly connected to a pressure plate 29. The pressure plate 29 is fixed to the top inner wall of the movable frame 27, thus forming a spring reset mechanism.

[0070] When the movable frame 27 moves due to external force, the first spring 30 is compressed or stretched. Once the external force disappears, the first spring 30 will use its own elastic force to push the pressure plate 29, thereby causing the movable frame 27 to return to its original position. This design ensures that the movable frame 27 can remain in a fixed position when it is not subjected to external force, thus improving the stability and reliability of the floodlight.

[0071] Reference Figure 2 A placement slot 38 is specially designed on one side of the floodlight 3. This placement slot 38 is used to accommodate and fix the filter 39. The filter 39 is an important component that can change the color of the light emitted by the floodlight 3, thereby meeting different lighting needs. In order to ensure that the filter 39 can be stably fixed in the placement slot 38, a rotating plate 40 is also rotatably connected to one side of the floodlight 3. The design of this rotating plate 40 is very ingenious. It can not only limit the filter 39 to prevent it from moving or falling off in the placement slot 38, but also position the rotating plate 40 through the magnetic attraction between the first magnet strip 41 on it and the second magnet strip 42 on the floodlight 3, ensuring that it can be firmly fixed on the floodlight 3.

[0072] Example 2

[0073] refer to Figure 10 and Figure 11 Improvements based on Embodiment 1: In addition, an L-shaped limiting plate 13 is fixedly connected to each of the two support arms 2 on the side away from each other. The design of this L-shaped limiting plate 13 is mainly to limit the rotating disk 7 and prevent it from detaching from the support arm 2 during rotation. At the same time, a red marking strip 14 is also fixedly embedded on the top of the L-shaped limiting plate 13. This red marking strip 14 is used to determine the distance the rotating disk 7 moves, thereby helping the user to more accurately control the rotation angle and position of the rotating disk 7.

[0074] refer to Figure 10 and Figure 11 It is worth mentioning that the L-shaped limiting plate 13 is made of transparent acrylic material. This material not only has good transparency, allowing the movement distance of the rotating disk 7 to be clearly observed, but also has excellent weather resistance and processing performance, enabling the L-shaped limiting plate 13 to be used for a long time in various harsh environments without deformation or damage.

[0075] refer to Figure 10 and Figure 11During use, when the rotating disk 7 drives the cylinder 8 to rotate, the user can clearly observe the moving distance of the rotating disk 7 due to the transparent acrylic material of the L-shaped limiting plate 13. When the rotating disk 7 moves to the position of the red marking strip 14, the insertion rod 6 and the pin 12 will be inserted into the slot 4 and the pin hole 5, thereby initially clamping and fixing the floodlight 3. At this time, the rotating disk 7 and the first trapezoidal block 34 are also in initial contact. Through this design, the user can accurately judge whether the floodlight 3 is clamped and fixed by observing the cooperation between the L-shaped limiting plate 13 and the red marking strip 14. After the floodlight 3 is clamped and fixed, the supporting effect of the auxiliary plate 17 is automatically released, thereby improving the installation efficiency and ease of use of the floodlight.

[0076] A method for using a combination floodlight includes the following steps:

[0077] S1. During assembly, the base 1 is installed on the fixed frame using the cross-slot bolt 23. Then, the auxiliary plate 17 is pushed up until the iron block 16 and the neodymium magnet 20 cooperate. The magnetic attraction between the neodymium magnet 20 and the iron block 16 firmly attracts the auxiliary plate 17 to the top inner wall of the slide 15. Then, the floodlight 3 is placed on the auxiliary plate 17 to support the auxiliary plate 17, which facilitates the insertion of the rod 6 and the pin 12 into the slot 4 and the pin hole 5 later.

[0078] S2. Rotate the rotating disk 7, which drives the cylinder 8 to rotate. The cylinder 8 is threadedly connected to the internal thread groove 9. The rotating disk 7, the insert rod 6, and the mounting plate 11 move toward the floodlight 3 until the insert rod 6 and the pin 12 are initially inserted into the slot 4 and the pin hole 5. At this time, the initial fixing of the floodlight 3 is completed.

[0079] S3. As the rotating disk 7 continues to rotate, the insertion rod 6 and the pin 12 further clamp and fix the floodlight 3. One side of the rotating disk 7 cooperates with the inclined surface of the first trapezoidal block 34, which can push the first trapezoidal block 34, the Z-shaped rod 33 and the second trapezoidal block 35 to move down. The inclined surface of the second trapezoidal block 35 cooperates with the moving frame 27 to push the moving frame 27 to the left. The moving frame 27 drives the rack 28 to move. The rack 28 drives the rubber rod 19 to rotate through the gear 21. At this time, the rubber rod 19 rotates 90°. The neodymium magnet 20 above the rubber rod 19 is just misaligned with the iron block 16, releasing the magnetic attraction between the neodymium magnet 20 and the iron block 16, releasing the support of the auxiliary plate 17 for the floodlight 3, and allowing the illumination angle of the floodlight 3 to be adjusted later.

[0080] S4. When the auxiliary plate 17 falls, the elastic force of the first spring 30 drives the moving frame 27 and the rack 28 to reset, and the rubber rod 19 rotates 90° in the opposite direction. When the auxiliary plate 17 falls on the base 1, the cross-slot bolt 23 extends into the relief groove 26, which can protect the cross-slot bolt 23. The iron column 24 is inserted into the round groove 25. The neodymium magnet 20 below the rubber rod 19 generates a magnetic attraction force on the iron column 24, which can firmly attract the auxiliary plate 17 to the base 1, avoid dust accumulation in the cross slot on the cross-slot bolt 23, and facilitate loosening the cross-slot bolt 23 and disassembling the base 1 later.

[0081] S5. When it is necessary to change the lighting color, rotate the rotating plate 40 to release the blockage of the filter 39, and then the filter 39 can be replaced. The operation is convenient, and different colored filters 39 can be replaced as needed. In addition, when the rotating disk 7 drives the cylinder 8 to rotate, since the L-shaped limiting plate 13 is made of transparent acrylic, the distance the rotating disk 7 moves can be observed through the L-shaped limiting plate 13. When the rotating disk 7 moves to the position of the red marking strip 14, the insertion rod 6 and the pin 12 are just inserted into the slot 4 and the pin hole 5, initially clamping the floodlight 3. At this time, the rotating disk 7 and the first trapezoidal block 34 are in initial contact. Then, through the cooperation of the L-shaped limiting plate 13 and the red marking strip 14, the supporting effect of the auxiliary plate 17 can be automatically released after the floodlight 3 is clamped and fixed.
