[0073] Specifically, refer to Figure 1 and Figure 2In this embodiment, the entire device is assembled from a shell 100, a rotating mechanism 200, a light source 300, an outer ring assembly 400, and a shell cover 500. After assembly, only the shell 100, the outer ring assembly 400, and the shell cover 500 can be observed from the outside, and the rest are internal components. Therefore, after assembly, the overall appearance of the device is simple and the connection is firm, which can achieve dustproof and waterproof effects, thereby being able to adapt to different working environments. Among them, the shell 100 adopts a hollow cylindrical structure with an open upper bottom surface. A first cavity 110 is surrounded by all the walls of the shell 100. The first cavity 110 is a cylinder. The rotating mechanism 200 is arranged in the first cavity 110, and a stud is provided on the lower bottom surface of the shell 100 for fixing the shell 100 to the rotating mechanism 200 in combination with screws. The light source 300 is fixed to the lower bottom surface of the shell 100 or a position close to the lower bottom surface, and is arranged directly below the rotating mechanism 200, so that the rotating mechanism 200 can completely block the light emitted upward by the light source 300; the light source 300 can adopt a light source composed of LED lamps, and has a disposable or rechargeable power supply inside, or, the power supply required by the light source 300 is fixed to the base part at the bottom of the shell cover 500, and the light source 300 is electrically connected to the power supply, so that the light source 300 does not need to be powered by an external power supply in real time during operation, and the light source 300 can emit uniform and stable light upward; or, a wire inlet hole is provided on the bottom surface of the shell cover 500, and the light source 300 is electrically connected to the external power supply wire through the wire inlet hole, so that the light source 300 can emit uniform and stable light upward. The outer ring assembly 400 is in the shape of a circular ring as a whole, and screws are fixed on the inner side of the ring, which is fixedly connected to the rotating mechanism through the screws. When the outer ring assembly 400 is fixedly connected to the rotating mechanism 200, the cylindrical side wall of the shell 100 is located between the two, that is, a through hole 120 is provided on the cylindrical side wall of the shell 100. The through hole 120 is arranged at the same height along the cylindrical side wall of the shell 100, and can connect the first cavity 110 on the inside of the shell 100 with the outside of the shell 100. The outer ring assembly 400 is fixedly connected to the rotating mechanism 200 through the through hole 120. After the device is assembled as a whole, an external force is applied to the outer ring assembly 400 located on the outside of the shell 100 to make it rotate, which can drive the rotating mechanism 200 located in the first cavity 110 inside the shell 100 to perform the same rotational movement.

[0074] Reference Figure 3, wherein the rotating mechanism 200 mainly includes: a fixed base plate 210, a connecting plate 220, a linkage shaft 230, a sliding block 240 and a horizontal plate 250. The fixed base plate 210 is a circular plate structure as a whole. It is fixedly connected to the studs on the bottom surface of the shell 100 by means of the base plate fixing holes 213 provided thereon, thereby fixing the rotating mechanism 200 to the shell 100 as a whole. The base plate fixing holes 213 are provided on the plate body between the inner circle and the outer circle of the circular structure, and there are two of them, distributed on the same diameter of the circular ring; the fixed base plate 210 is provided with a first slide rail 211, which is provided on the fixed base plate 210. On another diameter of the annular surface of the fixed base plate 210, the diameter is not the same as the diameter of the base plate fixing holes 213. The first slide rail 211 adopts a groove-type slide rail structure. The fixed base plate 210 is also provided with a plurality of (four or more) fixing bolt holes 212, which are evenly distributed on the edge of the annular surface of the fixed base plate 210. In contrast, the connecting plate 220 is provided with a plurality of (four or more) fixing bolts 222, and the fixing bolts 222 are located at the same upper and lower positions as the fixing bolt holes 212. The two are fixedly connected by a bolt and stud structure, so that the fixed base plate 210 is fixedly connected to the connecting plate 220, and the connecting plate 220 is located above the fixed base plate 210; the connecting plate 220 as a whole also adopts a circular plate structure, and the inner circle radius and outer circle radius of the connecting plate 220 are the same as the inner circle radius and outer circle radius of the fixed base plate 210; a second slide rail 221 is also provided on the connecting plate 220, and the position of the second slide rail 221 is the same as that of the first slide rail 211. The second slide rail 221 is located right above the first slide rail 211, and the second slide rail 221 adopts a through-hole structure, and the through-hole can pass through the upper and lower bottom surfaces of the connecting plate 220 and is connected to the inner circle of the connecting plate 220. Therefore, the length of the second slide rail 221 is slightly shorter than that of the first slide rail 211, that is, the second slide rail 221 does not completely pass through the entire outer diameter of the connecting plate 220, thereby ensuring that the connecting plate 220 as a whole will not be divided into two completely unconnected parts by the second slide rail 221. Two linkage shafts 230 are provided, and the two linkage shafts 230 adopt exactly the same columnar structure, are located between the first slide rail 211 and the second slide rail 221, and are positioned opposite to the first slide rail 211 and the second slide rail 221 up and down. The lower end of the linkage shaft 230 is in sliding contact with the first slide rail 211, and the shape of the lower end of the linkage shaft 230 is matched with the shape of the first slide rail 211, so that the lower end of the linkage shaft 230 can just slide along the first slide rail 211; the upper end of the linkage shaft passes through the second slide rail 221 and is in sliding contact with the second slide rail 221, and the columnar side part of the upper end of the linkage shaft 230 in sliding contact with the second slide rail 221, its shape is just matched with the shape of the second slide rail 221, so that the upper end side part of the linkage shaft 230 can just slide along the second slide rail 221.Two sliding blocks 240 are provided, which are respectively fixed on the shaft bodies of the two linkage shafts 230. The two sliding blocks 240 adopt the same structure, which is approximately a semicircular plate. The sliding blocks 240 are located between the connecting plate 220 and the fixed base plate 210. When the upper and lower ends of the linkage shaft 230 slide on the first slide rail 211 and the second slide rail 221 respectively, the two sliding blocks 240 can be driven to move in the horizontal direction along the direction of the first slide rail 211 and the second slide rail 221, thereby controlling the adhesion and separation of the two sliding blocks 240, and when the two sliding blocks 240 are in the adhesion state, they can completely cover the inner circle of the fixed base plate 210 in the upper and lower directions, thereby completely blocking the light emitted upward from the light source 300 located below the fixed base plate 210. Therefore, the upward luminous flux is directly controlled according to the distance between the two sliding blocks 240 and the degree of opening and closing. The connecting plate 220 is also provided with 2 to 4 stepped screw holes 223. Correspondingly, the rotating mechanism 200 also includes 2 to 4 stepped screws 270. The number of stepped screws 270 is equal to that of the stepped screw holes 223. The upper and lower positions of the stepped screws 270 are relative and fixedly connected. The horizontal plate 250 as a whole also adopts a circular plate structure, and the inner and outer radii of the horizontal plate 250 are the same as the inner and outer radii of the fixed base plate 210. The horizontal plate 250 is in sliding contact with the stepped screws 223 through a guide groove in the shape of an arc through hole, and the horizontal plate 250 is also in sliding contact with the upper end of the linkage shaft 230 through another guide groove in the shape of an arc through hole, so that all stepped screws 223 and the linkage shaft 230 can slide along their respective guide grooves. The horizontal plate 250 is also fixedly connected to the outer ring assembly 400 through a screw hole and a screw structure. The outer ring assembly 400 is fixedly connected to the horizontal plate 250 through the through hole 120, so that after the overall assembly of the device, it is aligned with the shell. The outer ring assembly 400 on the outside of the body 100 applies an external force to rotate it, which can drive the horizontal plate 250 on the rotating mechanism 200 located in the first cavity 110 inside the shell 100 to rotate relative to other parts of the rotating mechanism 200. At the same time, since the horizontal plate 250 is in sliding contact with the linkage shaft 230, it has a guiding effect on the movement of the linkage shaft 230, thereby converting the horizontal rotational movement of the horizontal plate 250 driven by the outer ring assembly 400 into a horizontal linear movement of the linkage shaft 230 along the first slide rail 211 or the second slide rail 221, thereby controlling the distance and opening and closing degree between the two sliding blocks 240, thereby controlling the luminous flux of the light source 300 in the vertical upward direction.By arranging the light source 300 between the rotating mechanism 200 and the shell 100, and the rotating mechanism 200 adopts a transmission structure of a first slide rail 211, a second slide rail 221, a linkage shaft 230 and a sliding block 240, the movement of the linkage shaft 230 is linked by external rotational motion, thereby controlling the opening and closing of the internal sliding block 240, and the size of the luminous flux is determined by the degree of opening and closing between the sliding blocks 240, thereby achieving the technical effect of controlling the luminous flux in a single direction by external rotational motion, which is used to adjust and control the light output to adapt to different environmental requirements. The device adopts a unique rotation and linear motion linkage design to achieve flexible control and adjustment of the luminous flux; and the size of the luminous flux is determined by the degree of opening and closing between the sliding blocks 240, so that more precise and quantifiable control of the luminous flux can be achieved. Regarding the quantifiable control of luminous flux, more specifically, in this embodiment, the light emitted by the light source 300 is emitted from directly below the two sliding blocks 240. The different opening and closing degrees of the two sliding blocks 240 can effectively control the amount of light output. For example, let the amount of light output be Φ, the light-transmitting diameter of the horizontal plate 250 (that is, the inner diameter of the horizontal plate 250) be 20 mm, and the rotation angle of the horizontal plate 250 be θ. When the rotation angle is 40°, the two sliding blocks 240 are completely closed. Based on the state that the sliding blocks 240 are completely closed, let the sliding distance of the sliding block 240 be X, then according to the geometric principle:

[0075] The sliding distance X of a single-piece slider and θ follow the following relationship:

[0076] X=(θ / 40°)*10mm=(θ / 4)mm

[0077] Maximum light output area:

[0078] S1=πr 2 =(100π)mm 2

[0079] Blocked area:

[0080] S cover

[0081] =4*(S1*arccos(10 / (10-(θ / 4)) / 360)-1 / 2*(10-(θ / 4))*10 / sin(arccos(10 / (10-(θ / 4))))) Actual light output area:

[0082] Sout=S1-Scover

[0083] Actual light output:

[0084] Φactual=Φ*(Sout / S1)

[0085] Therefore, according to the above-mentioned geometric principle, by controlling the angle of the rotating outer ring assembly 400, it is possible to accurately achieve quantifiable control over the actual light output.

[0086] Reference Figure 3 and Figure 4 Furthermore, in some embodiments of the present invention, the horizontal plate 250 further includes:

[0087] A first guide circular groove 251 is provided on the horizontal plate 250 , and the first guide circular groove 251 is in sliding contact with the linkage shaft 230 ;

[0088] A second guide circular groove 252 is provided on the horizontal plate 250 , and the step screw 270 is in sliding contact with the second guide circular groove 252 ;

[0089] The first screw hole 253 is fixedly connected to the outer ring assembly 400 by screws.

[0090] Specifically, in this embodiment, two first guide circular grooves 251 are provided and are 180° apart from each other. The two first guide circular grooves 251 are exactly the same in shape and size, and both adopt an involute circular arc groove structure, that is, a spiral arc-shaped through-hole structure extending from the center of the circle to the outside; the two first guide circular grooves 251 are in sliding contact with the two linkage shafts 230 respectively, so that when the horizontal plate 250 rotates in the horizontal direction, the first guide circular groove 251 provided on the horizontal plate 250 can drive the linkage shaft 230 in sliding contact therewith to make horizontal linear motion along the direction of the first slide rail 211 and the second slide rail 221, thereby controlling the opening and closing of the sliding block 240 fixed on the linkage shaft 230. The second guide circular grooves 252 are provided in the horizontal plate 250 and are in sliding contact with the step screws 270, thereby slidably connecting the entire horizontal plate 250 with the step screws 270. The number of second guide circular grooves 252 is the same as the number of step screws 270, and the use of a circular arc through-hole structure ensures that the horizontal plate 250 will not be hindered by the step screws 270 when rotating in the horizontal direction. The first screw holes 253 are fixedly connected to the outer ring assembly 400 via screws, thereby fixing the horizontal plate 250 and the outer ring assembly 400, allowing the outer ring assembly 400 to drive the horizontal plate 250 to rotate.

[0091] Reference Figure 3 and Figure 4 Furthermore, in some embodiments of the present invention, the step screw 270 further includes:

[0092] Lubricating washer 271 is disposed between step screw 270 and second guide circular groove 252 and is fixedly connected to step screw 270. Specifically, in this embodiment, the use of lubricating washer 271 can reduce friction between step screw 270 and second guide circular groove 252 when horizontal plate 250 rotates, thereby preventing wear between the two, and ensuring that the entire horizontal plate 250 is not hindered by step screw 270 when rotating in the horizontal direction.

[0093] Reference Figure 3 and Figure 4 Furthermore, in some embodiments of the present invention, the rotating mechanism 200 further includes a limiting device 260, and the limiting device 260 includes:

[0094] The limiting seat 261 is a hollow structure and is provided with a second cavity 261a;

[0095] The rotating shaft 262 passes through the second cavity 261a, and both sides of the rotating shaft 262 are fixedly connected to the limiting seat 261;

[0096] The rotating block 263 is disposed in the second cavity 261 a and is rotatably connected to the rotating shaft 262 .

[0097] Specifically, in this embodiment, the limit device 260 is fixedly connected to the horizontal plate 250 and is used to cooperate with the outer ring assembly 400 to achieve a one-touch locking and unlocking function. The limit seat 261 is a cylindrical hollow structure with an open upper bottom surface. Its side walls and bottom wall together form a second cavity 261a. The rotating shaft 262 is a cylindrical structure that passes through the second cavity 261a. Both sides of the rotating shaft 262 are fixedly connected to the through holes on the side walls of the limit seat 261. The rotating block 263 is disposed in the second cavity 261a and is rotatably connected to the rotating shaft 262. The rotating block 263 is provided with a semi-open arc-shaped through hole that fits exactly against the cylindrical side wall of the rotating shaft 262, thereby enabling the rotating block 263 to rotate around the cylindrical side wall of the rotating shaft 262. When the rotating block 263 receives external force, it can rotate ±17.5° around the rotating axis 262. The direction and angle of rotation depend on the force direction of the rotating block 263. This structure is used to cooperate with the outer ring assembly 400 to realize the manual switch lock function.

[0098] Reference Figure 3 and Figure 4 Furthermore, in some embodiments of the present invention, the limiting device 260 further includes:

[0099] A second screw hole 261b is provided on the limiting seat 261;

[0100] The limiting seat locking screw 264 is threadedly connected to the second screw hole 261b, and the limiting seat locking screw 264 is fixedly connected to the horizontal plate 250. Specifically, in this embodiment, the second screw hole 261b and the limiting seat locking screw 264 cooperate with each other to be fixedly connected, thereby being used to fix the limiting device 260 to the horizontal plate 250.

[0101] Reference Figure 5 and Figure 6 Furthermore, in some embodiments of the present invention, the outer ring assembly 400 includes:

[0102] The outer ring 410 includes an inner side of the outer ring 410 and an outer side of the outer ring 410 . The inner side of the outer ring 410 is in close contact with the housing 100 . The outer ring 410 is configured to rotate around the housing 100 .

[0103] The fixed block 420 is disposed inside the outer ring 410 and is fixedly connected to the outer ring 410 . The fixed block 420 is also fixedly connected to the rotating mechanism 200 .

[0104] Specifically, in this embodiment, the outer ring 410 adopts a circular ring belt structure, and the inner ring diameter is equal to or close to the outer wall diameter of the shell 100. During assembly, the inner side of the outer ring 410 can just completely fit the outer wall of the shell 100, and when the outer ring 410 is rotated, it will not suffer from excessive friction from the outer wall of the shell 100, causing difficulty in rotation. The fixed block 420 is arranged on the inner side of the outer ring 410, and the fixed block 420 and the outer ring 410 are threadedly fixed using an external screw 422; a first screw 421 is also provided on the fixed block 420, and the first screw 421 is used to be threadedly connected to the first screw hole 253, thereby fixing the horizontal plate 250 to the fixed block 420 and the outer ring 410, so that the outer ring 410 can drive the horizontal plate 250 to rotate.

[0105] Reference Figure 5 and Figure 6 Furthermore, in some embodiments of the present invention, the outer ring assembly 400 further includes:

[0106] A limit switch 430 , wherein one side of the limit switch 430 extends to the outside of the outer ring 410 , and the other side of the limit switch 430 extends to the inside of the outer ring 410 ;

[0107] A positioning shaft 440 , the positioning shaft 440 is fixedly connected to the limit switch 430 , and the positioning shaft 440 is in sliding contact with the outer ring 410 ;

[0108] A bead screw 431 is provided on the portion of the limit switch 430 extending to the inner side of the outer ring 410 ;

[0109] The housing 100 is further provided with a slot 130 , which is communicated with the through hole 120 .

[0110] Specifically, in this embodiment, referring to Figure 5 The limit switch 430 passes through the ring wall of the outer ring 410, and the outer operating part 432 of the limit switch extends on the outside of the outer ring 410 and fits with the outer wall of the outer ring 410. The inner part of the limit switch 430 extends on the inner side of the outer ring 410, and the tail shape of the inner part of the limit switch 430 fits with the shape of the second cavity 261a. Therefore, the tail of the inner part of the limit switch 430 can just be engaged with the limit seat 261 structure, and the entire limit switch 430 can move up and down along the axial direction of the outer ring 410. The positioning shaft 440 is a cylindrical, thin rod-shaped structure, which is fixedly connected to the limit switch 430. The positioning shaft is embedded in the ring wall of the outer ring 410. When the entire limit switch 430 can move up and down along the axial direction of the outer ring 410, it will also drive the positioning shaft in the ring wall of the outer ring 410 to move up and down. The positioning shaft 440 is used to connect the limit switch 430 and the outer ring 410 so that they can slide up and down. The tail portion of the limit switch 430 extending to the inner side of the outer ring 410 is provided with a glass bead screw 431. The glass bead screw 431 cooperates with the elastic mechanism in the tail of the limit switch 430 to realize an elastic stroke variable structure. When the glass bead screw 431 is not subjected to external force, the glass bead screw 431 protrudes outward from the tail of the limit switch 430. When the glass bead screw 431 is subjected to external pressure, the structure will retract. At this time, the glass bead screw 431 will retract into the tail of the limit switch 430. When the external force is removed, the elastic force of the elastic mechanism in the tail of the limit switch 430 will restore the stroke of the glass bead screw 431 and return to the state of protruding outward from the tail of the limit switch 430. Figure 6After the outer ring assembly 400 is assembled with the horizontal plate 250, the tail of the inner ring part of the limit switch 430 can be engaged with the limit seat 261 structure, and the bead screw 431 set at the tail of the inner ring part of the limit switch 430 is retracted and assembled with the rotating block 263, that is, the two are pressed and contacted with each other, so that when the outer ring operating part 432 of the limit switch is toggled up and down by external force, the tail of the inner ring part of the limit switch 430 and the bead screw 431 can be driven to move up and down, and because the bead screw 431 is in the process of moving up and down , and squeeze each other with the rotating block 263, thereby driving the rotating block 263 to rotate around the rotating shaft 262. At the same time, the bead screw 431 is elastically expanded and contracted under pressure. Due to the existence of this elastic force and the squeezing effect between the rotating block 263 and the bead screw 431, after the outer operating part 432 of the limit switch ring is moved up and down by an external force, the current rotation angle of the rotating block 263 and the current position of the limit switch 430 can be maintained, and the current position of the limit switch 430 will not change due to the action of gravity or other small interference forces. Furthermore, when the outer operating part 432 of the limit switch ring is pushed upward, the entire limit switch 430 will drive the bead screw 431 to move upward to above the rotating block 263. At the same time, the position of the inner part of the limit switch 430 will move upward from the through hole 120 to the slot 130, thereby being limited in the horizontal direction by the slot 130, so that the entire outer ring assembly 400 cannot rotate in the horizontal direction. As a result, the horizontal plate 250 fixedly connected to the outer ring assembly 400 cannot rotate in the horizontal direction, and it is impossible to drive the sliding block 240 to open and close through the linkage shaft 230, thereby realizing the locking function of the current luminous flux, that is, realizing the manual locking function of the device. Similarly, when the device needs to be manually unlocked, the outer operating part 432 of the limit switch ring is pushed downward, and the entire limit switch 430 will drive the glass bead screw 431 to move downward to the bottom of the rotating block 263. At the same time, the position of the inner part of the limit switch 430 will move downward from the slot 130 to the through hole 120, thereby disengaging from the horizontal limit of the slot 130, so that the entire outer ring assembly 400 can resume rotation in the horizontal direction. As a result, the horizontal plate 250 fixedly connected to the outer ring assembly 400 can resume rotation in the horizontal direction, and thus can resume the ability to drive the sliding block 240 to open and close through the linkage shaft 230, thereby realizing the unlocking function of the current luminous flux, that is, realizing the manual unlocking function of the device. Multiple slots 130 can be provided as needed to achieve locking and unlocking of different luminous flux levels. Furthermore, the width of the slots 130 must be consistent with and fit within the inner ring portion of the limit switch 430, ensuring that the inner ring portion of the limit switch 430 fits snugly within the slots 130 and cannot move horizontally. Thus, the above structure enables the device to quickly lock and unlock luminous flux.

[0112] The shell cover 500 is detachably connected to the housing 100 .

[0113] Specifically, in this embodiment, the shell cover 500 is a hollow cylindrical structure with an open bottom surface. The inner wall of the cylinder is provided with a spiral pattern. The shell cover 500 and the housing 100 are spirally assembled and connected via the spiral pattern. This structure facilitates the assembly and disassembly of the housing 100 and the shell cover 500, facilitating the maintenance and repair of the equipment. At the same time, it also allows the shell cover 500 and the interior of the housing 100 to form a stable and enclosed space, thereby protecting the internal components and making the device suitable for different working environments. The upper bottom surface of the shell cover 500 can be made of a light-transmitting material such as glass or transparent plastic according to actual needs, so that the light emitted upward by the light source 300 via the rotating mechanism 200 can penetrate the upper bottom surface of the shell cover 500.

[0115] The fixing bolts 222 are used to fix the connecting plate 220 to the fixed base plate 210 .

[0116] Specifically, in this embodiment, the fixed base plate 210 is further provided with a plurality of (four or more) fixing bolt holes 212, which are evenly distributed on the edge of the annular surface of the fixed base plate 210. Correspondingly, the connecting plate 220 is provided with a plurality of (four or more) fixing bolts 222. The fixing bolts 222 are located at upper and lower positions relative to the fixing bolt holes 212 and are equal in number. The two are fixedly connected by a bolt and stud structure, thereby fixing the fixed base plate 210 and the connecting plate 220. The fixed connection by the bolt and stud structure can make the fixing between the fixed base plate 210 and the connecting plate 220 more firmly secured.
