Technical Field

[0001] The present invention belongs to the technical field of energy-saving lighting, and particularly relates to an adjusting device for an LED lamp with a reset spring. Background Art

[0002] LED lamps are a commonly used energy-saving lighting device. In the field of lighting devices, the design of lamp brackets and legs plays a key role in the usability and functionality of the lamps. Most of the existing lamp brackets and legs only have two basic forms, that is, the legs are extended in a supporting state to support the lamp bracket and provide stable support for lighting; and the legs are in a retracted state, which is convenient for carrying and storage. However, these traditional designs have obvious deficiencies. Currently, the legs on the market usually do not have a height adjustment function and cannot flexibly adjust the height of the lamp according to the actual use scenario, which to a certain extent limits the use range and effect of the lamp. In addition, although some lamp brackets have a folding function for convenient carrying, there is a lack of effective positioning and adjustment mechanisms during the folding and unfolding processes, and the operation is not convenient enough.

[0003] With the continuous improvement of people's requirements for the use of lighting devices, such as in working environments at different heights, places with different spatial layouts, etc., it is necessary for the lamps to be able to quickly and conveniently adjust the height. Therefore, it is of great practical significance to develop a lamp bracket adjusting device that can not only flexibly adjust the height but also be conveniently folded when carried.

Specific embodiments

[0030] In order to further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail in conjunction with the accompanying drawings.

[0031] The structure of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0032] As Figures 1 to 9 shown, an adjusting device for an LED lamp with a return spring provided by an embodiment of the present invention includes a first support tube 1, a second support tube 2 slidably connected in the first support tube 1 for carrying the LED lamp 18, a mounting ring 3 sleeved outside the first support tube 1, at least three groups of ear plates 4 fixedly connected to the mounting ring 3, an arc-shaped slideway 5 provided on the ear plate 4, and a plurality of clamping grooves 6 fixedly connected to the outer edge of the arc-shaped slideway 5; a leg 7 is rotatably connected to the ear plate 4, a rectangular slideway 8 is provided inside the leg 7, a first clamping rod 9 is slidably arranged inside the rectangular slideway 8, the first clamping rod 9 is connected to the end of the rectangular slideway 8 through a first return spring 10, and the first clamping rod 9 can be clamped in one of the clamping grooves 6.

[0033] The adjusting device for the LED lamp with a return spring is mainly composed of components such as the first support tube 1, the second support tube 2, the mounting ring 3, the ear plate 4, the leg 7, the first clamping rod 9 and the first return spring 10. The second support tube 2 for carrying the LED lamp is slidably connected in the first support tube 1, the mounting ring 3 is sleeved outside the first support tube 1, at least three groups of ear plates 4 are fixedly connected to the mounting ring 3, the arc-shaped slideway 5 is provided on the ear plate 4, and a plurality of clamping grooves 6 are fixedly connected to its outer edge, and the leg 7 is rotatably connected to the ear plate 4.

[0034] When it is necessary to adjust the height of the LED lamp, press the first clamping rod 9 in the rectangular slideway 8 inside the support leg 7. The first clamping rod 9 slides in the rectangular slideway 8 while compressing the first return spring 10, so that the first clamping rod 9 disengages from the current clamping groove 6. At this time, the support leg 7 can rotate around the rotation point on the ear plate 4. During the process of rotating the support leg 7, find a suitable height position so that the first clamping rod 9 aligns with another clamping groove 6. After the first clamping rod 9 aligns with the new clamping groove 6, release the force pressing the first clamping rod 9. Due to the elastic restoring force of the first return spring 10, the first clamping rod 9 is pushed into the new clamping groove 6, thereby realizing the fixation of the position of the support leg 7 and completing the height adjustment. When it is necessary to carry this LED lamp, also press the first clamping rod 9 to make it disengage from the clamping groove 6, and then rotate the support leg 7 to a position parallel to the first support tube 1. At this time, the volume of the entire device is greatly reduced, which is convenient for carrying and storing.

[0035] In one embodiment, the mounting ring 3 is fixedly connected to the first support tube 1, for example, by welding. When in an environment with uneven ground, the stability of the LED lamp will be affected, which may cause the lamp to tilt and affect the lighting effect. In this case, the structural design of the mounting ring 3 fixedly connected to the first support tube 1 in this adjustment device plays an important role. Since the mounting ring 3 is fixedly connected to the first support tube 1, each support leg 7 is rotatably connected to the mounting ring 3 through the ear plate 4, and the first clamping rod 9 on the support leg 7 cooperates with the clamping groove 6 on the outer edge of the arc-shaped slideway 5 of the ear plate 4 to achieve positioning. When the ground is uneven, each support leg 7 can independently rotate around the rotation point on the ear plate 4 according to the height difference of the ground at its location. When the ground under a certain support leg 7 is lower, press the first clamping rod 9 inside the support leg 7 to make it disengage from the current clamping groove 6, and then rotate the support leg 7 downward to make the support leg 7 adapt to the lower ground height. Until a suitable angle is found, release the first clamping rod 9, and under the action of the first return spring 10, the first clamping rod 9 is clamped into the new clamping groove 6 to realize the fixation of this support leg 7. Similarly, if the ground under a certain support leg 7 is higher, the support leg 7 can be rotated upward for adjustment. By independently adjusting the angles of each support leg 7, the inclination degrees of different support legs 7 are different, so that the support surface of the LED lamp can adapt to the unevenness of the ground, and finally the leveling of the LED lamp is realized, ensuring that the lamp is in a horizontal state and providing stable lighting.

[0036] Furthermore, a first clamping hole 11 is provided on the first support tube 1; a second clamping rod 23 is fixedly connected to the side of the support leg 7, and a notch 24 is provided on the second clamping rod 23;

[0037] A second return spring 12 is provided inside the first support tube 1. The upper end of the second return spring 12 is connected to the lower end of the second support tube 2. The second support tube 2 is slidably connected inside the first support tube 1. A second clamping hole 13 is provided on the second support tube 2. The second clamping rod 23 can be clamped in the first clamping hole 11 and the second clamping hole 13. And under the push of the second return spring 12, the edge of the second clamping hole 13 can be clamped into the notch 24.

[0038] When putting away the device, push the second support tube 2 into the first support tube 1, and at the same time press the second return spring 12 until the second clamping hole 13 and the first clamping hole 11 are aligned. Then fold the leg 7 so that the leg 7 is parallel to the first support rod. At the same time, the first clamping rod 9 is clamped into the first clamping hole 11 and the second clamping hole 13. And under the push of the second return spring 12, the edge of the second clamping hole 13 is clamped into the notch 24 to improve the clamping effect. Through this setting, quick folding can be completed. And by pressing the second support tube 2 downward and folding the leg 7 upward at the same time, the space occupied by the whole device can be reduced, which is convenient for transportation. On the contrary, when in use, when the first clamping rod 9 is disengaged from the first clamping hole 11 and the second clamping hole 13, the second support tube 2 can automatically reset under the action of the second return spring 12.

[0039] Furthermore, there are at least 4 legs 7, and several groups of the second clamping holes 13 are provided.

[0040] Through this setting, the following effects are achieved: First, if all 4 legs 7 are used to support the ground, the stability can be increased; Second, when in use, different second clamping holes 13 and the first clamping holes 11 can be aligned, so that one of the legs 7 is folded to a position parallel to the first support tube 1, and the first clamping rod 9 is clamped in the first clamping hole 11 and the second clamping hole 13. Through this setting, on the one hand, the second support tube 2 can be adjusted to different heights, on the other hand, the elastic shaking of the second support tube 2 can be prevented, and at least 3 remaining legs 7 can still support the device.

[0041] Preferably, when the second support tube 2 is propped up by the second return spring 12, the bottom of the second support tube 2 is aligned with the first clamping hole 11. Through this setting, when in use, the first clamping rod 9 can be used to support the bottom of the second support tube 2 to reduce its shaking.

[0042] In one embodiment, the mounting ring 3 is slidably arranged on the first support tube 1; a plurality of strip holes 14 are provided on the first support tube 1, and the strip holes 14 are equidistantly arranged in the axial direction of the first support tube 1; a third clamping rod 15 is fixedly connected to the end of the leg 7 close to the first support tube 1, and the third clamping rod 15 is clamped in the strip holes 14.

[0043] When in use, the mounting ring 3 and the different strip holes 14 can be aligned, and the third clamping rod 15 can be clamped into the strip hole 14, so that the position of the mounting ring 3 can be fixed, thereby adjusting the height of the leg 7. Another advantage is that the mounting ring 3 and the leg 7 are easy to install and remove.

[0044] Specifically, the upper end of the second support tube 2 is fixedly connected with a mounting frame 16, and a control box 17 is provided on the side of the mounting frame 16. The output end of the control box 17 is connected to the LED lamp 18 through a wire, and the input end of the control box 17 is connected to a power line. The inner wall of the clamping groove 6 is provided with a rubber buffer layer. When the first clamping rod 9 is clamped into the clamping groove 6, the rubber buffer layer can reduce the collision and wear between the first clamping rod 9 and the clamping groove 6, and at the same time increase the stability and quiet effect of the clamping.

[0045] Furthermore, a non-slip foot pad 19 is provided at the bottom of the leg 7. The non-slip foot pad 19 is made of rubber or silicone material and has non-slip texture on the surface, which can increase the friction between the leg 7 and the ground to prevent the lamp from sliding during use; the upper end of the leg 7 is covered with a rubber sleeve 20, and the outer side of the rubber sleeve 20 is in contact with the inner side of the ear plate 4; the upper end of the leg 7 is rotatably connected to the ear plate 4 by a bolt 21.

[0046] Furthermore, the inner wall of the first support tube 1 is provided with a smooth wear-resistant coating, which can reduce the sliding friction between the first support tube 1 and the second support tube 2, so that the second support tube 2 can slide more smoothly in the first support tube 1, while extending the service life of the support tube; a plastic limiting ring 22 is fixedly connected to the upper end of the first support tube 1, and the second support tube 2 slides in contact with the plastic limiting ring 22.

[0047] Working principle of the present invention:

[0048] When the height of the LED lamp needs to be adjusted, the first clamping rod 9 in the rectangular slide 8 inside the leg 7 is pressed, and the first clamping rod 9 slides in the rectangular slide 8, and the first return spring 10 is compressed at the same time, so that the first clamping rod 9 is separated from the current clamping groove 6. At this time, the leg 7 can rotate around the rotation point on the ear plate 4. In the process of rotating the leg 7, find a suitable height position so that the first clamping rod 9 is aligned with another clamping groove 6. When the first clamping rod 9 is aligned with the new clamping groove 6, release the force pressing the first clamping rod 9, and the first return spring 10 pushes the first clamping rod 9 into the new clamping groove 6 due to the elastic restoring force, so as to fix the position of the leg 7 and complete the height adjustment. When the LED lamp needs to be carried, the first clamping rod 9 is also pressed to separate it from the clamping groove 6, and then the leg 7 is rotated to a position parallel to the first support tube 1. At this time, the volume of the entire device is greatly reduced, which is convenient for carrying and storage.
