Description

Technical Field

[0001] This invention relates to the field of shadowless lamp technology, and in particular to a fully adjustable shadowless lamp pole base structure and its usage method. Background Technology

[0002] A shadowless lamp is a specially designed lighting device that avoids shadows. It is typically used in situations requiring precise illumination, such as operating rooms and laboratories. Its design features multiple bulbs and a complex reflector system to ensure that when the light is applied to the target area, no shadows are created due to changes in the angle of the light, guaranteeing uniform light that does not interfere with operation. Shadowless lamps are generally divided into fixed and mobile types.

[0003] In the existing technology, the height adjustment of the lamp post of traditional mobile shadowless lamps is inconvenient and difficult for personnel to operate. Secondly, the base is generally moved by casters, which have poor braking ability and make it difficult to ensure the stability of the shadowless lamp during use. Therefore, this application proposes a fully adjustable shadowless lamp post base structure and usage method to solve the above problems. Summary of the Invention

[0004] The purpose of this application is to provide a fully adjustable shadowless lamp pole base structure and usage method to solve the problems mentioned in the background art, such as the inconvenience of adjusting the lamp pole height of traditional mobile shadowless lamps, which makes them difficult for personnel to operate; secondly, the base is generally moved by casters, which have poor braking ability and make it difficult to ensure the stability of the shadowless lamp during use.

[0005] To achieve the above objectives, this application provides the following technical solution: a fully adjustable shadowless lamp pole base structure, including a base, and the shadowless lamp further includes: The support legs are configured as four, and all four support legs are fixedly installed on the outside of the base, and all four support legs are fixedly installed with casters at the bottom. The lower light pole has its bottom end fixedly installed on the top of the base. A stabilizing slider is slidably connected inside the lower light pole. An upper light pole is fixedly installed on the top of the stabilizing slider. The top end of the upper light pole extends to the outside of the lower light pole. A positioning slot is provided on the right side of the upper light pole. A braking assembly is disposed at the bottom of the base and is used to stably position the base. The positioning assembly includes a positioning rod, a second spring, and a limiting support rod. A rectangular mounting hole is provided on the inner wall of the right side of the lower light pole. The positioning rod is rotatably connected inside the rectangular mounting hole. The left end of the positioning rod is engaged with the positioning slot. The limiting support rod is fixedly installed on the inner wall of the lower light pole. The bottom of the positioning rod is in contact with the bottom of the limiting support rod. The bottom end of the second spring is fixedly installed on the right side of the lower light pole, and the top end of the second spring is fixedly installed on the bottom of the positioning rod. A horizontal bar for mounting the shadowless lamp is slidably connected to the top of the upper lamp pole, and a multi-angle adjustment rod is rotatably connected to the bottom of the horizontal bar. The multi-angle adjustment rod is rotatably connected to the main body of the shadowless lamp. An adjustment component is used to adjust the position of the main body of the shadowless lamp. The adjustment component is located on the right side of the upper lamp post and cooperates with the horizontal bar for mounting the shadowless lamp. The device is secured to the outside of the base with four casters, allowing for flexible movement. The lower lamp post is fixed to the top of the base, while the upper lamp post is slidably connected to the lower lamp post via a stabilizing slider for height adjustment. A positioning slot works with a positioning component, which includes a positioning rod, a second spring, and a limiting support rod. The positioning rod can rotate under the action of the second spring and engage with the positioning slot, thus quickly locking the extension height of the upper lamp post. This makes operation convenient and effortless. The shadowless lamp mounting crossbar is slidably connected to the top of the upper lamp post and is connected to the shadowless lamp body via a multi-angle adjustment rod, allowing for flexible adjustment of the lighting angle. The adjustment component works with the shadowless lamp mounting crossbar to further fine-tune the horizontal position of the shadowless lamp body. A braking component is located at the bottom of the base, providing stable braking after the device is moved into position. The overall structure achieves convenient adjustment and reliable fixation of height, horizontal position, and angle, significantly improving operational efficiency and stability during use.

[0006] Preferably, a first spring is fixedly installed on the bottom inner wall of the lower lamp post, and the top end of the first spring is fixedly installed on the bottom of the stabilizing slider. By setting the first spring, the downward pulling force of the upper lamp post can be increased, making the positioning clip and the positioning slot more securely engaged.

[0007] Preferably, an mounting plate is fixedly installed on the right side of the lower lamp post, and a limiting screw is threadedly connected to the limiting support rod. The top end of the limiting screw cooperates with the bottom end of the positioning clamp rod. By tightening the limiting screw, its top end can be pressed against the positioning clamp rod, which helps to fix the rotation position of the positioning clamp rod and prevents it from coming out of the positioning groove when the equipment vibrates or is accidentally collided. This provides double protection for height locking and further enhances the structural stability of the lamp post after extension, ensuring that the shadowless lamp has no risk of shaking when in operation.

[0008] Preferably, the braking assembly includes an electric push rod and an electric suction cup. The bottom of the base has a mounting groove. The electric push rod is fixedly installed on the top inner wall of the mounting groove, and the top of the electric suction cup is fixedly installed on the output shaft of the electric push rod. When the device moves to the target position, the electric push rod is controlled to extend and push the electric suction cup downward to contact the ground. After the electric suction cup is powered on, it generates negative pressure to firmly adhere to the ground, providing strong static friction, thereby effectively locking the position of the base. This overcomes the shortcomings of insufficient braking ability when relying solely on the universal wheel brake, and greatly ensures the overall stability of the shadowless lamp during use.

[0009] Preferably, four telescopic rods are fixedly installed on the outer side of the electric suction cup. The top ends of the four telescopic rods are all fixedly installed on the top inner wall of the mounting groove. The telescopic rods play a guiding and stabilizing role during the lifting and lowering of the electric suction cup driven by the electric push rod, preventing the electric suction cup from deflecting or shaking during lifting and lowering, ensuring that it can vertically and stably contact and detach from the ground, making the action of the braking component more precise and reliable. At the same time, the telescopic rods share some of the lateral force, protect the mechanism of the electric push rod, and extend the service life of the braking component.

[0010] Preferably, a rectangular sliding sleeve is fixedly installed at the top of the upper lamp post. The rectangular sliding sleeve is slidably fitted onto the horizontal bar of the shadowless lamp installation. The rectangular sliding sleeve provides a smooth sliding track and support for the horizontal movement of the horizontal bar of the shadowless lamp installation, so that the horizontal bar of the shadowless lamp installation moves smoothly without jamming or swaying when it drives the shadowless lamp body to adjust its lateral position, ensuring the accuracy of the shadowless lamp positioning. The rectangular sliding sleeve has a simple structure and low frictional resistance, making the adjustment operation easy and effortless.

[0011] Preferably, the adjustment assembly includes an adjustment screw, an adjustment nut, and a connecting rod. The left end of the adjustment screw is rotatably connected to the right side of the upper lamp post. The adjustment nut is threaded onto the adjustment screw. The top and bottom ends of the connecting rod are respectively fixedly installed at the bottom of the shadowless lamp mounting crossbar and the top of the adjustment nut. By rotating the adjustment screw, the adjustment nut can be driven to move along the screw axis. In turn, the connecting rod drives the shadowless lamp mounting crossbar and the shadowless lamp body to make precise horizontal position adjustments. This mechanical adjustment method is stable and reliable, and can achieve stepless precise positioning, meeting the needs of fine control of the light spot position in surgical lighting.

[0012] Preferably, a rotating seat is installed on the right side of the upper lamp post, and the left end of the adjusting screw is fixedly installed on the rotating seat. The rotating seat provides a stable rotation fulcrum for the adjusting screw, ensuring that the axial position of the adjusting screw is fixed during rotation and there is no radial movement. This makes the movement trajectory of the adjusting nut more linear and precise. At the same time, the rotating seat reduces the frictional resistance when the adjusting screw rotates, making the rotation operation smoother and the adjustment process easier.

[0013] This invention also proposes a method for using a fully adjustable shadowless lamp pole base structure, comprising the following steps: S1: Push the equipment to the target position via the casters, and connect the main body of the shadowless lamp, the electric push rod and the electric suction cup to the external power supply; S2: Control the extension of the electric push rod to push the electric suction cup downward to contact the ground. The electric suction cup is powered on to generate negative pressure to adhere to the ground, thus completing the stable braking of the base. S3: Pull the upper light pole upwards. When the desired height is reached, the positioning lever rotates and engages with the positioning slot. Tighten the limit screw to press the positioning lever against the positioning lever, thereby locking the height of the upper light pole. S4: Rotate the adjusting screw to push the horizontal bar of the shadowless lamp installation, initially adjust the horizontal position of the shadowless lamp body, and then finely adjust the horizontal position of the shadowless lamp body. S5: Rotate the multi-angle adjustment lever to flexibly adjust the main lighting angle of the shadowless lamp.

[0014] The beneficial effects of this invention are: 1. The device is fixed to the outside of the base by four outriggers with casters, allowing for flexible movement. The lower lamp post is fixed to the top of the base, and the upper lamp post is slidably connected to the lower lamp post via a stabilizing slider to achieve height adjustment. The positioning slot cooperates with the positioning component, which includes a positioning rod, a second spring, and a limit support rod. The positioning rod can rotate under the action of the second spring and engage with the positioning slot, thereby quickly locking the extension height of the upper lamp post. The operation is convenient and labor-saving. The shadowless lamp mounting crossbar is slidably connected to the top of the upper lamp post and is connected to the shadowless lamp body via a multi-angle adjustment rod, enabling flexible adjustment of the lighting angle. The adjustment component cooperates with the shadowless lamp mounting crossbar to further fine-tune the horizontal position of the shadowless lamp body. The braking component is located at the bottom of the base, providing stable braking after the device is moved into place. The overall structure achieves convenient adjustment and reliable fixation of height, horizontal position, and angle, significantly improving operating efficiency and stability during use. 2. By setting up a braking component, when the equipment moves to the target position, the electric push rod is extended to push the electric suction cup downward to contact the ground. After the electric suction cup is powered on, it generates negative pressure to firmly adhere to the ground, providing strong static friction, thereby effectively locking the position of the base. This overcomes the shortcomings of relying solely on the universal wheel brake for insufficient braking ability and greatly ensures the overall stability of the shadowless lamp during use. 3. By rotating the adjusting screw, the adjusting nut can be driven to move along the screw axis, which in turn drives the horizontal bar of the shadowless lamp and the main body of the shadowless lamp to make precise horizontal position adjustments through the connecting rod. This mechanical adjustment method is stable and reliable, and can achieve stepless precise positioning, meeting the needs of fine control of the spot position in surgical lighting. This invention solves the problem of inconvenient height adjustment of traditional mobile shadowless lamp poles, making operation easy; at the same time, it achieves stable braking through electric push rod and electric suction cup, overcoming the shortcomings of poor braking ability; it can also conveniently adjust the height, horizontal position and angle of the shadowless lamp and reliably fix it, improving operating efficiency and usage stability.

[0017] The present invention will be further explained below with reference to specific embodiments.

[0018] refer to Figures 1-5 This embodiment proposes a fully adjustable shadowless lamp pole base structure, including a base 1, which is made of circular metal. Four legs 2 are evenly fixed to the outer side of the base 1. Each leg 2 has a caster wheel 3 welded to its bottom, which has a braking function to allow for equipment movement and temporary fixation. A lower lamp pole 4 is welded to the center of the top of the base 1. The lower lamp pole 4 is a hollow cylindrical metal pole with a slidably connected stabilizing slider 6 inside. The stabilizing slider 6 is a rectangular metal block, and an upper lamp pole 5 is welded to its top. The upper lamp pole 5 is also a hollow cylindrical metal pole, with its top extending to the outside of the lower lamp pole 4. Multiple positioning slots 8 are evenly spaced along the axial direction on the right side. A first spring 7 is welded to the inner wall of the bottom of the lower lamp pole 4. The top of the first spring 7 is welded to the bottom of the stabilizing slider 6, providing downward pulling force for the upper lamp pole 5.

[0019] A rectangular mounting hole 9 is formed on the inner wall of the right side of the lower light pole 4. A positioning rod 10 is rotatably connected inside the rectangular mounting hole 9. The positioning rod 10 is an L-shaped metal rod, and its left end can be engaged with the positioning slot 8. A mounting plate 13 is welded to the right side of the lower light pole 4. A limiting support rod 12 is threadedly connected to the mounting plate 13. A limiting screw 14 is threadedly connected to the limiting support rod 12. The top of the limiting screw 14 can abut against the bottom of the positioning rod 10. A second spring 11 is also welded to the right side of the lower light pole 4. The top of the second spring 11 is welded to the bottom of the positioning rod 10 to provide a return spring force for the positioning rod 10.

[0020] A rectangular sliding sleeve 15 is welded and fixed to the top of the upper lamp post 5. The rectangular sliding sleeve 15 is slidably fitted onto the shadowless lamp mounting crossbar 16. The shadowless lamp mounting crossbar 16 is a cylindrical metal rod that can slide horizontally within the rectangular sliding sleeve 15. A multi-angle adjustment rod 17 is rotatably connected to the bottom of the shadowless lamp mounting crossbar 16. The multi-angle adjustment rod 17 is a metal rod that can rotate in multiple directions, and its end is rotatably connected to the shadowless lamp body 18, realizing flexible adjustment of the lighting angle of the shadowless lamp body 18.

[0021] An adjustment assembly is installed on the right side of the upper lamp post 5. The adjustment assembly includes an adjustment screw 20, an adjustment nut 21, and a connecting rod 22. A rotating seat 19 is welded and fixed to the right side of the upper lamp post 5. The left end of the adjustment screw 20 is fixedly installed on the rotating seat 19. The adjustment nut 21 is threaded onto the adjustment screw 20. The top and bottom ends of the connecting rod 22 are welded and fixed to the bottom of the shadowless lamp mounting crossbar 16 and the top of the adjustment nut 21, respectively. Rotating the adjustment screw 20 can drive the adjustment nut 21 to move along the screw axis, thereby causing the shadowless lamp mounting crossbar 16 and the shadowless lamp body 18 to make minor adjustments to their horizontal positions.

[0022] A mounting groove 23 is formed at the bottom of the base 1. An electric push rod 24 is welded and fixed to the inner wall of the top of the mounting groove 23. An electric suction cup 25 is welded and fixed to the output shaft of the electric push rod 24. Four telescopic rods 26 are welded and fixed to the outside of the electric suction cup 25. The top ends of the telescopic rods 26 are welded and fixed to the inner wall of the top of the mounting groove 23. After the equipment moves to the target position, the electric push rod 24 is controlled to extend and push the electric suction cup 25 downward to contact the ground. The electric suction cup 25 is energized to generate negative pressure to adhere to the ground, realizing the stable braking of the base 1.

[0023] In use, the device is moved to the target position via the casters 3. The electric push rod 24 is extended to allow the electric suction cup 25 to contact the ground and adhere, thus braking the base 1. Pulling the upper lamp post 5 upward causes the stabilizing slider 6 to slide within the lower lamp post 4. When the desired height is reached, the positioning lever 10 rotates under the action of the second spring 11 and engages with the positioning slot 8. Simultaneously, the limit screw 14 is tightened to press against the positioning lever 10, and the first spring 7 provides downward pulling force, making the engagement more secure and locking the height of the upper lamp post 5. Pushing the shadowless lamp mounting crossbar 16 to slide within the rectangular sliding sleeve 15 allows for initial adjustment of the horizontal position of the shadowless lamp body 18. Rotating the adjusting screw 20, through the adjusting nut 21 and connecting rod 22, enables precise fine-tuning of the horizontal position of the shadowless lamp mounting crossbar 16 and the shadowless lamp body 18. Rotating the multi-angle adjusting rod 17 allows for flexible adjustment of the illumination angle of the shadowless lamp body 18. The overall structure achieves convenient adjustment and reliable fixation of height, horizontal position, and angle, significantly improving operational efficiency and stability during use.

[0024] This invention also proposes a method for using a fully adjustable shadowless lamp pole base structure, comprising the following steps: S1: Push the device to the target position via the caster wheel 3, and connect the shadowless lamp body 18, electric push rod 24 and electric suction cup 25 to the external power supply; S2: Control the electric push rod 24 to extend, push the electric suction cup 25 downward to contact the ground, the electric suction cup 25 is powered to generate negative pressure to adhere to the ground, and complete the stable braking of the base 1. S3: Pull the upper light pole 5 upward. When the required height is reached, the positioning rod 10 rotates and engages with the positioning slot 8. Tighten the limit screw 14 to press against the positioning rod 10, thereby locking the height of the upper light pole 5. S4: Rotate the adjusting screw 20 to push the horizontal bar 16 of the shadowless lamp installation, initially adjust the horizontal position of the shadowless lamp body 18, and then finely adjust the horizontal position of the shadowless lamp body 18. S5: Rotate the multi-angle adjustment rod 17 to flexibly adjust the illumination angle of the shadowless lamp body 18.

[0025] It should be noted that the specific model of the shadowless lamp body 18, electric push rod 24, and electric suction cup 25 used shall be selected by those skilled in the art. Furthermore, the above-mentioned shadowless lamp body 18, electric push rod 24, and electric suction cup 25 are all existing technologies, and this solution will not elaborate on them.

[0026] Working principle: When in use, first connect the main body 18 of the shadowless lamp, the electric push rod 24 and the electric suction cup 25 to the external power supply. Then push the equipment to the target position. It can move flexibly by using the four support legs 2 on the outside of the base 1 with the universal wheels 3 with brake function at the bottom. After it is in place, control the electric push rod 24 welded and fixed in the mounting groove 23 at the bottom of the base 1 to extend, push the electric suction cup 25 welded and fixed on its output shaft to contact the ground downward. The electric suction cup 25 is powered on and generates negative pressure to adhere to the ground. At the same time, the four telescopic rods 26 welded and fixed on the outside of the electric suction cup 25 guide and stabilize it as it rises and falls, ensuring that the electric suction cup 25 contacts the ground vertically and stably, and completing the stable braking of the base 1. Next, pull the upper light pole 5 upward. The stabilizing slider 6, which is welded and fixed at the bottom of the upper light pole 5, slides inside the lower light pole 4. The first spring 7, which is welded and fixed on the inner wall at the bottom of the lower light pole 4, applies a downward pulling force to the stabilizing slider 6. When the upper light pole 5 reaches the required height, the L-shaped positioning rod 10, which is rotatably connected in the rectangular mounting hole 9 on the inner wall of the right side of the lower light pole 4, rotates under the elastic force of the second spring 11, which is welded and fixed on the right side of the lower light pole 4. Its left end engages with the positioning slot 8, which is equidistantly opened along the axial direction on the right side of the upper light pole 5. At the same time, tighten the limiting screw 14 on the limiting support rod 12, which is threaded and connected to the mounting plate 13 on the right side of the lower light pole 4, so that its top end abuts against the bottom of the positioning rod 10. The pulling force of the first spring 7 makes the engagement more stable, thus locking the height of the upper light pole 5. Pushing the rectangular sliding sleeve 15, which is welded and fixed to the top of the upper lamp post 5, and slidingly fitting the horizontal rod 16 of the shadowless lamp installation, allows for initial adjustment of the horizontal position of the shadowless lamp body 18, which is rotatably connected to the end of the multi-angle adjusting rod 17 at the bottom of the horizontal rod 16. Then, rotating the adjusting screw 20 fixed on the rotating seat 19 on the right side of the upper lamp post 5 drives the adjusting nut 21 threaded onto it to move axially along the screw. The adjusting nut 21, through the connecting rod 22 welded and fixed to the bottom of the horizontal rod 16 and the top of the adjusting nut 21 respectively, drives the horizontal rod 16 and the shadowless lamp body 18 to perform precise horizontal position adjustments. Rotating the multi-angle adjusting rod 17 allows for flexible adjustment of the illumination angle of the shadowless lamp body 18. Through the above operations, the overall structure achieves convenient adjustment and reliable fixation of height, horizontal position, and angle, significantly improving operational efficiency and stability during use.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
