Description

Technical Field

[0001] This utility model belongs to the field of lamp angle adjustment technology, specifically a portable lamp multi-angle rotation and fixing mechanism. Background Technology

[0002] Lighting fixtures are devices used for illumination, widely used in various environments such as homes, offices, and public places. Lights convert electrical energy into light energy, providing a light source and improving visual conditions. Common lighting fixtures include chandeliers, wall lamps, table lamps, and floor lamps, employing technologies such as incandescent lamps, fluorescent lamps, and LED lamps. Among these, LED lamps have become the mainstream choice due to their high energy efficiency, long lifespan, and environmental friendliness. Lighting fixture designs are also becoming increasingly diverse, emphasizing not only practicality but also aesthetic appeal, making them an important element of interior decoration. Furthermore, portable lighting fixtures are needed when working outdoors or in dimly lit places. To accurately project light onto the areas that need illumination and avoid wasting light or shining it on unwanted areas, lighting fixtures are equipped with multi-angle adjustment mechanisms.

[0003] In the prior art, after the angle of the lamp is adjusted, its rotating structure is easily worn due to long-term use, which causes the lamp to be unable to maintain the set angle and thus change the angle due to the influence of gravity.

[0004] Therefore, this utility model provides a portable lamp multi-angle rotation and fixing mechanism. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A portable lamp multi-angle rotating and fixing mechanism of this utility model includes a lamp holder; a light strip is fixedly connected to both sides of the lamp holder; a light-emitting component is rotatably connected to the middle of the lamp holder; an outer ring is fixedly connected to the outer side of the light-emitting component; multiple movable rings are slidably connected to the middle of the outer ring; a pull rope is fixedly connected to the bottom of the movable ring; a fixing block is fixedly connected to one end of the pull rope; first sliding grooves are provided on both sides of the fixing block; two first springs are fixedly connected to one end of the first sliding grooves; a slider is fixedly connected to one end of each first spring; the slider is slidably connected to the first sliding groove; multiple grooves are provided at the bottom of the outer ring; the grooves are formed on the surface of the lamp holder; slots are provided on both sides of the grooves; the grooves engage with the fixing block; and the slots are slidably connected to the slider. During operation, the light strip is bound to an appropriate position, and then the light-emitting component is rotated to adjust its position. After the light-emitting component is turned on, the light can illuminate the designated position. Initially, the fixing block will be locked between the light-emitting component and the outer ring. Before adjusting the position of the light-emitting component, the fixing block... After removing the block and adjusting the light-emitting component, pull the rope to make the movable ring slide on the outer ring, moving the movable ring to the position closest to the light-emitting component and the lamp holder. Press the slider, compress the first spring, and make the slider lock into the first groove. Then, lock the fixing block into the nearest groove. When the first groove and the groove align, the first spring rebounds, pushing the slider into the groove. This achieves the fixing effect after the angle of the light-emitting component is adjusted. Based on the function of the component that rotates between the bottom of the light-emitting component and the lamp holder, the rope pulls the light-emitting component, reducing the possibility of the rotating component at the bottom of the light-emitting component loosening after long-term use, which could cause the angle of the light-emitting component to become unstable. By setting the outer ring, movable ring, rope, fixing block, and groove, the light-emitting component is further traction and fixed after the angle is adjusted, reducing the possibility of the light-emitting component loosening after long-term use, which could cause the light-emitting component to lose its angle. This can extend the service life of the rotating component at the bottom of the light-emitting component. The first groove, first spring, slider, and groove strengthen the fixing and locking effect of the fixing block and the groove, making the traction of the light-emitting component by the rope more stable.

[0007] Preferably, a second slide groove is provided at the top of the first slide groove. The second slide groove is located in the middle of the fixed block. A slide rod is slidably connected in the second slide groove. One end of the slide rod is fixedly connected to the slider, and the other end of the slide rod is fixedly connected to a handle. During operation, when the fixed block is removed from the groove, the handle is pushed in the direction of the pull rope, and the slide rod slides in the second slide groove, thereby pulling the slider to slide in the first slide groove, so that the slider disengages from the slot, and the fixed block can be removed from the groove. By setting the second slide groove, the slide rod, and the handle, it is easy for the slider to disengage from the slot, and thus it is easy for the fixed block to be removed from the groove.

[0008] Preferably, a first magnetic block is fixedly connected to the middle of the slot, and a second magnetic block is fixedly connected to the bottom of the fixing block. When the fixing block is engaged with the groove during operation, the first magnetic block and the second magnetic block cooperate to attract each other. The outer ring is made of iron. When the fixing block is not in use, it is attracted and fixed to the outer ring by the second magnetic block.

[0009] Preferably, an anti-slip washer is fixedly connected to the middle of the movable ring. The anti-slip washer is in corresponding contact with the outer ring. During operation, the anti-slip washer protects the outer ring and the movable ring. Under the pull of the rope, the outer ring and the movable ring will squeeze each other, causing damage. At the same time, the anti-slip washer increases the friction between the outer ring and the movable ring, reducing the possibility of slippage between the outer ring and the movable ring.

[0010] Preferably, the pull rope is provided with a protective cloth on the outside. One end of the protective cloth is fixedly connected to the movable ring, and the other end of the protective cloth is fixedly connected to the fixing block. During operation, the protective cloth protects the pull rope and reduces the possibility of the pull rope breaking due to external factors. Both the protective cloth and the pull rope have a certain degree of elasticity.

[0011] Preferably, a second spring is sleeved in the middle of the protective cloth. The second spring is sleeved with the pull rope. One end of the second spring is fixedly connected to the movable ring, and the other end of the second spring is fixedly connected to the fixed block. During operation, the second spring supports the protective cloth, reducing the impact of external debris on the pull rope when it damages the protective cloth. At the same time, it protects the elasticity of the pull rope and extends its service life.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The portable lamp multi-angle rotation and fixing mechanism of this utility model, by setting an outer ring, a movable ring, a pull rope, a fixing block, and a groove, further pulls and fixes the light-emitting component after adjusting the angle, reducing the possibility of the light-emitting component loosening after long-term use and causing the light-emitting component to be unable to maintain its angle. This can extend the service life of the rotating component at the bottom of the light-emitting component. The first slide groove, the first spring, the slider, and the slot enhance the fixing and locking effect of the fixing block and the groove, making the pull rope more stable in pulling the light-emitting component.

[0014] 2. The portable lamp multi-angle rotation fixing mechanism of this utility model, by setting a second sliding groove, a sliding rod and a handle, facilitates the disengagement of the slider from the slot, thereby making it easier to remove the fixing block from the groove.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown in the embodiment of this utility model, a portable lamp multi-angle rotating and fixing mechanism includes a lamp holder 1; lamp strips 11 are fixedly connected to both sides of the lamp holder 1; a light-emitting component 12 is rotatably connected to the middle of the lamp holder 1; an outer ring 13 is fixedly connected to the outer side of the light-emitting component 12; multiple movable rings 14 are slidably connected to the middle of the outer ring 13; a pull rope 15 is fixedly connected to the bottom of the movable rings 14; a fixing block 16 is fixedly connected to one end of the pull rope 15; first sliding grooves 17 are opened on both sides of the fixing block 16; two first springs 18 are fixedly connected to one end of the first sliding grooves 17; and a slider 19 is fixedly connected to one end of each first spring 18. Block 19 is slidably connected to the first sliding groove 17. The bottom of the outer ring 13 is provided with multiple grooves 110, which are formed on the surface of the lamp holder 1. Slots 111 are formed on both sides of each groove 110, engaging with the fixing block 16. The slots 111 are slidably connected to the slider 19. During operation, the light strip 11 is secured in a suitable position, and then the light-emitting component 12 is rotated to adjust its position. After the light-emitting component 12 is turned on, light can illuminate the designated location. Initially, the fixing block 16 is locked between the light-emitting component 12 and the outer ring 13. Before adjusting the position of the light-emitting component 12, the fixing block 16 is removed. After adjustment, pull the cord 15 again, causing the movable ring 14 to slide on the outer ring 13, moving the movable ring 14 to the position closest to the light-emitting component 12 and the lamp holder 1. Press down the slider 19, compressing the first spring 18, causing the slider 19 to engage in the first groove 17. Then, engage the fixing block 16 in the nearest groove 110. When the first groove 17 aligns with the slot 111, the first spring 18 rebounds, pushing the slider 19 into the groove 110. This achieves the fixing effect after the angle adjustment of the light-emitting component 12. Based on the function of the component that rotates between the bottom of the light-emitting component 12 and the lamp holder 1, the cord 15 pulls the light-emitting component 12, reducing the angle of the light-emitting component 12. The rotating component at the bottom may loosen after prolonged use, causing the angle of the light-emitting component 12 to become unstable. By setting an outer ring 13, a movable ring 14, a pull rope 15, a fixing block 16, and a groove 110, the angle of the light-emitting component 12 is adjusted and further traction is applied to fix it, reducing the possibility of the light-emitting component 12 becoming loose after prolonged use and thus failing to maintain its angle. This extends the service life of the rotating component at the bottom of the light-emitting component 12. The first slide groove 17, the first spring 18, the slider 19, and the slot 111 enhance the fixing and engaging effect between the fixing block 16 and the groove 110, making the traction of the light-emitting component 12 by the pull rope 15 more stable.

[0024] like Figures 1 to 3As shown, the top of the first slide groove 17 is provided with a second slide groove 2, which is located in the middle of the fixing block 16. A slide rod 21 is slidably connected in the second slide groove 2. One end of the slide rod 21 is fixedly connected to the slider 19, and the other end of the slide rod 21 is fixedly connected to a handle 22. When working, when the fixing block 16 is removed from the groove 110, the handle 22 is pushed in the direction of the pull rope 15, and the slide rod 21 slides in the second slide groove 2, thereby pulling the slider 19 to slide in the first slide groove 17, so that the slider 19 is disengaged from the slot 111, and the fixing block 16 can be removed from the groove 110. By setting the second slide groove 2, the slide rod 21, and the handle 22, it is convenient to disengage the slider 19 from the slot 111, and thus it is convenient to remove the fixing block 16 from the groove 110.

[0025] like Figures 1 to 4 As shown, a first magnetic block 3 is fixedly connected to the middle of the slot 111, and a second magnetic block 31 is fixedly connected to the bottom of the fixing block 16. When the fixing block 16 is engaged with the groove 110, the first magnetic block 3 and the second magnetic block 31 cooperate to attract each other. The outer ring 13 is made of iron. When the fixing block 16 is not in use, it is attracted and fixed to the outer ring 13 by the second magnetic block 31.

[0026] like Figures 1 to 5 As shown, an anti-slip washer 4 is fixedly connected to the middle of the movable ring 14. The anti-slip washer 4 is in corresponding contact with the outer ring 13. During operation, the anti-slip washer 4 protects the outer ring 13 and the movable ring 14. Under the pull of the rope 15, the outer ring 13 and the movable ring 14 will squeeze each other, causing damage. At the same time, the anti-slip washer 4 increases the friction between the outer ring 13 and the movable ring 14, reducing the possibility of slippage between the outer ring 13 and the movable ring 14.

[0027] like Figures 1 to 5 As shown, a protective cloth 5 is provided on the outside of the pull rope 15. One end of the protective cloth 5 is fixedly connected to the movable ring 14, and the other end of the protective cloth 5 is fixedly connected to the fixing block 16. During operation, the protective cloth 5 protects the pull rope 15 and reduces the occurrence of breakage of the pull rope 15 due to external factors. Both the protective cloth 5 and the pull rope 15 have a certain degree of elasticity.

[0028] like Figure 5 As shown, a second spring 6 is sleeved in the middle of the protective cloth 5. The second spring 6 is sleeved with the pull rope 15. One end of the second spring 6 is fixedly connected to the movable ring 14, and the other end of the second spring 6 is fixedly connected to the fixing block 16. During operation, the second spring 6 supports the protective cloth 5, reducing the impact on the pull rope 15 when external debris damages the protective cloth 5. At the same time, it protects the elasticity of the pull rope 15 and extends its service life.

[0029] Working principle: The light strip 11 is secured in a suitable position. Then, the light-emitting component 12 is rotated to adjust its position. After the light-emitting component 12 is turned on, the light can illuminate the designated location. Initially, the fixing block 16 is locked between the light-emitting component 12 and the outer ring 13. Before adjusting the position of the light-emitting component 12, the fixing block 16 is removed. After adjusting the light-emitting component 12, the pull rope 15 is pulled, causing the movable ring 14 to slide on the outer ring 13. The movable ring 14 is moved to the position closest to the light-emitting component 12 and the lamp holder 1. The slider 19 is pressed down, compressing the first spring 18, causing the slider 19 to engage in the first sliding groove 17. Then, the fixing block 16 is engaged in the nearest groove 110. When the first sliding groove 17 aligns with the groove 111, the first spring 18 rebounds, pushing... The movable slider 19 engages with the groove 110, thus achieving a fixed effect after the angle of the light-emitting component 12 is adjusted. Based on the function of the component that rotatably connects the bottom of the light-emitting component 12 to the lamp holder 1, the pull rope 15 pulls the light-emitting component 12, reducing the possibility of the rotating component at the bottom of the light-emitting component 12 loosening over time, which could lead to the inability to fix the angle of the light-emitting component 12. By setting the outer ring 13, movable ring 14, pull rope 15, fixing block 16, and groove 110, the light-emitting component 12 is further traction-fixed after angle adjustment, reducing the possibility of the light-emitting component 12 loosening over time, which could lead to the light-emitting component 12 being unable to maintain its angle. This extends the service life of the rotating component at the bottom of the light-emitting component 12. The first slide groove 17 and the first spring... Spring 18, slider 19, and slot 111 enhance the fixing and engaging effect of fixing block 16 and groove 110, making the pull rope 15 more stable in pulling the light-emitting component 12. When fixing block 16 is removed from groove 110, push handle 22 towards pull rope 15, slide rod 21 in second slide groove 2, and then pull slider 19 in first slide groove 17, so that slider 19 disengages from slot 111, and fixing block 16 can be removed from groove 110. By setting second slide groove 2, slide rod 21, and handle 22, it is easy for slider 19 to disengage from slot 111, and thus easy for fixing block 16 to be removed from groove 110. When fixing block 16 engages with groove 110, first magnetic block 3 and second magnetic block 31 cooperate to attract each other. Outer ring 13 is made of iron material, fixing When not in use, block 16 is magnetically attached to the outer ring 13 by the second magnetic block 31. The anti-slip washer 4 protects the outer ring 13 and the movable ring 14. Under the pull of the pull rope 15, the outer ring 13 and the movable ring 14 will squeeze each other, causing damage. At the same time, the anti-slip washer 4 increases the friction between the outer ring 13 and the movable ring 14, reducing the possibility of slippage between them. The protective cloth 5 protects the pull rope 15, reducing the possibility of breakage caused by external factors. Both the protective cloth 5 and the pull rope 15 have a certain degree of elasticity. The second spring 6 supports the protective cloth 5, reducing the impact of external debris on the pull rope 15 when it damages the protective cloth 5, while also protecting the elasticity of the pull rope 15 and extending its service life.
