Description

Technical Field

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

[0002] A floodlight is a lamp that provides a higher illuminance on a designated illuminated surface than the surrounding environment, also known as a spotlight. It can usually be aimed in any direction and has a structure that is not affected by weather conditions.

[0003] The patent application number is CN202221026216.1, which discloses a novel combined LED floodlight, which relates to the field of LED technology and includes an assembly frame, a support frame, an LED floodlight, and a replacement mechanism. The utility model provides a replacement mechanism that can facilitate maintenance of the LED floodlight. The LED floodlight drives the limiting plug to be inserted into the interior of the assembly frame, and the limiting plug squeezes the movable plug. At the same time, the pressing column, the movable plug, the lifting plate, the first spring, the rotating plate, and the limiting plug cooperate with each other, so that the movable plug is fixed to the limiting plug, which facilitates the convenient installation of the LED floodlight. At the same time, the limiting plug descends to squeeze the lifting slide. When the LED floodlight is to be maintained, the above operation is reversed, and the lifting slide, the second spring, the limiting rod, and the limiting plug cooperate with each other, so that the limiting plug drives the LED floodlight to automatically rise, thereby achieving maintenance and replacement of the LED floodlight.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: when in use, it is inconvenient to seal the connection of the floodlight. In order to prevent moisture, dust or other impurities from entering the lamp body, current floodlights usually install sealing rings at the combined connection for sealing. However, the sealing ring is squeezed for a long time, which can easily cause it to undergo plastic deformation or creep, thereby reducing the sealing effect of the floodlight. Utility Model Content

[0005] The utility model provides an LED combined floodlight, which solves the problem in the related art that it is inconvenient to perform sealing treatment on the connection parts of the floodlight.

[0006] The technical solution of the utility model is as follows: an LED combined floodlight, comprising: a base, a rotating mechanism provided in the base, a rotating frame provided on the top of the rotating mechanism, a connecting mechanism provided on the rotating frame, and a floodlight body rotatably connected to the rotating frame;

[0007] A notch is formed on one end surface of the main body of the floodlight, a lampshade is threadedly connected to the internal thread of the notch, a mounting groove is formed on one side of the inner wall of the notch, a sealed airbag is fixedly installed in the mounting groove, an air reservoir is fixedly installed on the top of the surface of the main body of the floodlight, and an air guide pipe is fixedly installed on the surface of the air reservoir, which passes through the main body of the floodlight and is connected to the sealed airbag;

[0008] One end of the gas cylinder is slidably connected to a movable rod, one end of the movable rod is fixedly connected to a piston that fits the inner wall of the gas cylinder, and a spring is sleeved on the surface of the movable rod;

[0009] The other end of the movable rod is fixedly connected to the limiting rod, and the surface of the lampshade is rotatably connected to an extrusion plate that is sleeved with the limiting rod.

[0010] Furthermore, the rotating mechanism includes a turntable rotatably connected to the base, an inner gear ring fixedly installed at the bottom of the turntable, and a power component arranged in the base.

[0011] The power component is composed of a motor fixedly installed in the base and a transmission gear fixedly connected to the output end of the motor and meshing with the internal gear ring.

[0012] Furthermore, the connection mechanism includes two screw holes symmetrically opened on the surface of the horizontal section of the rotating frame and the top of the turntable, and fixing bolts threadedly connected in the screw holes, and the ends of the fixing bolts are provided with a reinforcement mechanism.

[0013] Furthermore, the reinforcement mechanism includes a locking gear fixedly mounted on the top surface of the fixing bolt, a cylinder fixedly mounted on the top of the horizontal section of the rotating frame, a reset component arranged in the cylinder, and an arc-shaped toothed plate arranged at the end of the reset component and meshing with the locking gear.

[0016] The working principle and beneficial effects of the utility model are as follows:

[0017] When in use, the extrusion plate is put on the limit rod, and the lampshade and the floodlight main body are rotated to be connected and assembled. During the process, the extrusion plate slides and squeezes the movable rod, which drives the piston to slide and stretch the spring, and the gas is filled into the sealing airbag through the air guide tube. The sealing airbag expands and contacts the outer wall of the lampshade for sealing. When the lampshade is reversed and disassembled, the extrusion plate is separated from the movable rod, and the spring drives the piston to reset, and the gas in the sealing airbag is extracted, so that the sealing airbag shrinks, and then the connection between the lampshade and the floodlight main body is sealed. The sealing is achieved by air pressure, and does not rely on the elasticity of the sealing ring, which avoids the situation where the sealing ring is easily deformed under long-term pressure, thereby effectively improving the sealing effect and service life of the floodlight.

[0024] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1 - Figure 4An LED combined floodlight comprises: a base 1, a rotating mechanism is provided in the base 1, a rotating frame 2 is provided on the top of the rotating mechanism, a connecting mechanism is provided on the rotating frame 2, a floodlight body 3 is rotatably connected to the rotating frame 2, wherein the floodlight body 3 has an LED light source and a heat dissipation component, which is the existing technology in this field and will not be described in detail here;

[0026] A notch is provided on one end face of the main body 3 of the floodlight, and a lampshade 4 is threadedly connected to the inner wall of the notch. A mounting groove is provided on one side of the inner wall of the notch, and a sealing airbag 5 is fixedly installed in the mounting groove. A gas reservoir 6 is fixedly installed on the top of the surface of the main body 3 of the floodlight, and an air guide pipe is fixedly installed on the surface of the gas reservoir 6, which passes through the main body 3 of the floodlight and connects to the sealing airbag 5. The gas in the gas reservoir 6 is nitrogen, and the sealing airbag 5 is made of polyurethane material with high wear resistance and crack propagation resistance, and a wear-resistant agent is coated on its surface to further improve wear resistance.

[0027] One end of the air reservoir 6 is slidably connected to a movable rod 7, one end of the movable rod 7 is fixedly connected to a piston 8 that fits the inner wall of the air reservoir 6, and a spring 9 is sleeved on the surface of the movable rod 7, wherein the two ends of the spring 9 are respectively connected to the air reservoir 6 and the piston 8;

[0028] The other end of the movable rod 7 is fixedly connected to a limit rod 10 , and the surface of the lampshade 4 is rotatably connected to an extrusion plate 11 that is sleeved with the limit rod 10 .

[0029] When in use, first combine the lampshade 4 and the floodlight body 3, align the notches on the lampshade 4 and the floodlight body 3, and put the extrusion plate 11 on the limiting rod 10, then rotate the lampshade 4 and connect it to the floodlight body 3 through the thread to complete the combination. As the connection progresses of the lampshade 4, the extrusion plate 11 slides along the limiting rod 10 and contacts and squeezes the movable rod 7. At the same time, the movable rod 7 drives the piston 8 to slide in the gas cylinder 6 and stretches the spring 9, so that the gas in the gas cylinder 6 is filled into the sealing airbag 5 through the air guide tube. After the lampshade 4 is installed, the sealing airbag 5 is fully expanded and contacts the outer wall of the lampshade 4, filling and sealing the gap between the lampshade 4 and the floodlight body 3. When the lampshade 4 is reversed and disassembled, the extrusion plate 11 gradually separates from the movable rod 7. At this time, the spring 9 drives the piston 8 to reset, and the gas in the sealing airbag 5 is sucked into the air storage cylinder 6 for temporary storage, so that the sealing airbag 5 shrinks and separates from the outer wall of the lampshade 4, so as to reduce wear and tear, and then achieves the effect of sealing the connection combination of the lampshade 4 and the floodlight body 3. The sealing is achieved by air pressure, which does not rely on the elasticity of the sealing ring, avoiding the situation where the sealing ring is easily deformed under long-term pressure, effectively improving the sealing effect and service life of the floodlight. By setting up a connecting mechanism, it is convenient to connect the rotating frame 2 and the base 1, and the rotating mechanism is convenient to drive the floodlight body 3 to rotate and adjust.

[0030] Preferably, the rotating mechanism includes a turntable 12 rotatably connected to the base 1 , an inner gear ring 13 fixedly mounted on the bottom of the turntable 12 , and a power component provided in the base 1 .

[0031] The power component is composed of a motor 14 fixedly installed in the base 1 and a transmission gear 15 fixedly connected to the output end of the motor 14 and meshing with the internal gear ring 13.

[0032] Specifically, during use, the motor 14 drives the transmission gear 15 to rotate, and the internal gear ring 13 engaged therewith is driven to rotate, so that the turntable 12 drives the rotating frame 2 to rotate, so as to realize the rotation adjustment of the floodlight body 3, facilitate the expansion of the lighting range, and improve the flexibility of use.

[0033] Preferably, the connection mechanism includes two screw holes symmetrically provided on the surface of the horizontal section of the rotating frame 2 and the top of the turntable 12, and fixing bolts 16 threadedly connected in the screw holes. The ends of the fixing bolts 16 are provided with a reinforcement mechanism.

[0034] Specifically, by screwing the fixing bolts 16 into the screw holes on the rotating frame 2 and the turntable 12 in sequence, the rotating frame 2 and the turntable 12 are connected, which is convenient for later disassembly and maintenance. The fixing bolts 16 can be reinforced by the reinforcement mechanism to prevent them from rotating and causing the connection to become loose.

[0035] Preferably: the reinforcement mechanism includes a locking gear 17 fixedly mounted on the top surface of the fixing bolt 16, a cylinder 19 fixedly mounted on the top of the horizontal section of the rotating frame 2, a reset component provided in the cylinder 19, and an arc-shaped toothed plate 21 provided at the end of the reset component and meshing with the locking gear 17.

[0036] The reset component is composed of a fixed rod 18 that passes through and slides between the two ends of the cylinder 19 and a spring 20 that is fixedly connected between the opposite ends of the two fixed rods 18. The arc-shaped tooth plate 21 is fixedly connected to the other end of the fixed rod 18.

[0037] A movable groove is formed through the surface of the cylinder 19 , and movable blocks that slide in cooperation with the movable groove are integrally formed on the surfaces of the opposite ends of the two fixing rods 18 .

[0038] Specifically, when installing the fixing bolt 16, the two fixing rods 18 are moved relative to each other by the moving block to squeeze the spring 20 and drive the arc-shaped toothed plate 21 to move. Then the fixing bolt 16 is screwed into the screw hole to fix the rotating frame 2 and the turntable 12. Then the moving block is loosened, and the spring 20 drives the fixing rod 18 to reset, thereby driving the arc-shaped toothed plate 21 to reset and engage the locking gear 17, thereby reinforcing the fixing bolt 16 and preventing it from rotating and causing the rotating frame 2 to loosen.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
