Description

Technical Field

[0001] This utility model belongs to the technical field of lighting system speed card brackets, specifically relating to a telescopic adjustable speed card bracket for lighting systems that requires no welding. Background Technology

[0002] Traditional lighting system brackets are mostly made by on-site welding. In actual construction, before welding, a series of preparatory work must be completed, including equipment transportation, arrangement of welding machines and gas devices such as oxygen cylinders and acetylene cylinders, cleaning of the work site, and setting up of safety protection facilities such as fire blankets, splash guards, and setting up warning isolation areas. The process is cumbersome and time-consuming, extending the construction preparation cycle. At the same time, welding operations require a high level of technical skills from operators and pose safety hazards such as open flames, high temperatures, and harmful gases, which not only increases construction risks but also poses potential threats to the site environment and surrounding facilities. In addition, the welding process is prone to deformation and uneven welds, affecting the structural strength and appearance quality of the brackets, and thus affecting the stability and aesthetics of the lighting system.

[0003] More seriously, once traditional welded brackets are formed, their size and structure are fixed and cannot be flexibly adjusted according to the actual installation environment. When faced with different installation spacing, different wall thicknesses, or changes in space height, they often need to be recut, re-welded, or custom-made, resulting in low construction efficiency, serious material waste, and difficulty in meeting the needs of large-scale, rapid, and high-precision installation in modern lighting projects. Especially in temporary exhibitions, emergency lighting, modular buildings, or usage scenarios that require frequent disassembly and assembly, the irreversibility and unsuitability of traditional welded brackets have become key bottlenecks restricting construction progress and flexibility.

[0004] To address these issues, the applicant proposes a telescopic, adjustable, weld-free fastener bracket for a lighting system. Utility Model Content

[0005] The purpose of this utility model is to provide a telescopic adjustable weld-free fast-clamp bracket for lighting systems, in order to solve the problem of traditional welded brackets in the background art having fixed dimensions after forming, making it difficult to adapt to different installation environments. When the spacing, wall or height changes, they need to be recut and welded, which is inefficient and consumes a lot of materials. They cannot meet the needs of large-scale and fast-paced installations. Especially in scenarios such as temporary exhibitions and emergency lighting that require frequent disassembly and assembly, their irreversibility and lack of flexibility seriously restrict the construction progress.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A telescopic, adjustable, weld-free fastener bracket for a lighting system includes an upper frame. A nut is fixedly connected to the top of the upper frame, and a screw is threadedly connected to the inner cavity of the nut. One end of the screw passes through the side wall of an adjacent upper frame and is fixedly connected to a compression piece. A lower frame is located below the upper frame. A clamping mechanism is provided on one side of the lower frame. The clamping mechanism includes a first clamp, one side of which is fixedly connected to one side of an adjacent lower frame. A second clamp is provided on one side of the first clamp, and the two clamps are fixedly connected by two bolts. One side of clamp one has several mating slots, and one side of clamp two has several mounting slots. The inner cavity of the mating slot is provided with an elastic mechanism, which includes a damper. One end of the damper is fixedly connected to the inner wall of the adjacent mounting slot, and the other end of the damper is fixedly connected to the inner wall of the corresponding mounting slot. One side of the upper clamp frame is provided with an adapter mechanism, which includes a flat rod and a fixing plate. Vertical rods are fixedly connected to both sides of the top of the fixing plate, and one end of the vertical rod extends through the side wall of the flat rod to the top of the flat rod. The outer ring of the damper is fitted with a tension spring.

[0008] Preferably, one end of the tension spring is fixedly connected to the inner wall of the adjacent docking groove, and the other end of the tension spring is fixedly connected to the inner wall of the adjacent mounting groove.

[0009] Preferably, one side of the flat rod is fixedly connected to one side of the adjacent upper card frame, and one side of the lower card frame is fixedly connected to one side of the adjacent fixing plate.

[0010] Preferably, the bottom two sides of the flat rod are slidably connected to connecting seats, and one side of the connecting seat is fixedly connected to an insert rod, one end of which is inserted into the inner cavity of an adjacent insertion hole.

[0011] Preferably, a slider is fixedly connected to the top of the connecting seat, and grooves are provided on both sides of the bottom of the flat rod. The outer ring of the slider is slidably connected to the inner cavity of the adjacent groove.

[0012] Preferably, the outer ring of the bolt is fitted with a washer, and one end of the washer is in contact with one side of the adjacent clamp.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This solution effectively solves the problems of cumbersome preparation, high safety risks, and difficult adjustment associated with traditional welding brackets. Through a mechanical clamping structure composed of an upper and lower clamping frame, screws, and extrusion plates, on-site welding is eliminated, saving the preparation work of transporting welding machines, gas cylinders, and setting fire prevention measures. This significantly shortens preparation time, reduces labor intensity, and eliminates safety hazards such as open flames and high temperatures, improving construction safety and environmental friendliness. The damper and tension spring in the elastic mechanism provide buffering and automatic rebound functions, making clamping more stable and force distribution more even. The adapter mechanism, through the cooperation of flat rods, vertical rods, sliding grooves, sliders, connecting seats, insertion rods, and insertion holes, achieves height adjustment and multi-position locking to adapt to different installation environments. The clamping mechanism uses clamp one and clamp two in conjunction with bolts and washers to clamp the lighting pipes. It is detachable, easy to maintain, and suitable for frequent disassembly and assembly scenarios, avoiding material waste and improving construction efficiency and economy.

[0015] By setting an installation groove on one side of clamp two and a corresponding docking groove on one side of clamp one, the two clamps can form a clamping cavity with accurate alignment and tight fit when docked, which effectively improves the connection stability and centering accuracy between clamp one and clamp two. The cooperation between the installation groove and the docking groove provides installation space for the internal elastic mechanism, allowing the damper and tension spring to be arranged in an orderly manner and perform their buffering and reset functions normally. At the same time, this structure enhances the overall structural strength of the clamping mechanism, avoids clamp deformation or misalignment due to uneven force, and ensures uniform stress distribution when the bolts are tightened.

[0025] Example 1:

[0026] Please see Figure 1 - Figure 5As shown, a telescopic adjustable weldless fastener bracket for a lighting system includes an upper frame 1. A nut is fixedly connected to the top of the upper frame 1, and a screw 2 is threadedly connected to the inner cavity of the nut. One end of the screw 2 passes through the side wall of the adjacent upper frame 1 and is fixedly connected to a compression piece 3. A lower frame 8 is provided below the upper frame 1. A clamping mechanism 7 is provided on one side of the lower frame 8. The clamping mechanism 7 includes a first clamp 701. One side of the first clamp 701 is fixedly connected to one side of the adjacent lower frame 8. A second clamp 702 is provided on one side of the first clamp 701. One side of the first clamp 701 and one side of the second clamp 702 are fixedly connected by two bolts 703. Several docking slots 9 are provided. Several mounting slots 6 are provided on one side of the clamp 2 702. An elastic mechanism 5 is provided in the inner cavity of the docking slot 9. The elastic mechanism 5 includes a damper 501. One end of the damper 501 is fixedly connected to the inner wall of the adjacent mounting slot 6, and the other end of the damper 501 is fixedly connected to the inner wall of the corresponding mounting slot 6. An adapter mechanism 4 is provided on one side of the upper clamp frame 1. The adapter mechanism 4 includes a flat rod 401 and a fixing plate 402. Vertical rods 403 are fixedly connected to both sides of the top of the fixing plate 402. One end of the vertical rod 403 extends through the side wall of the flat rod 401 to the top of the flat rod 401. A tension spring 502 is sleeved on the outer ring of the damper 501.

[0027] As can be seen from the above, during the actual installation process, the personnel first move the telescopic adjustable weld-free quick-clamp bracket of the lighting system to the designated installation area and adapt it to the specific conditions of the wall or supporting structure on site. When it is necessary to fix the bracket to a protruding wall or steel structure, the personnel first observe the thickness of the wall and adjust the overall clamping size of the bracket accordingly. If the wall is thick, the personnel manually pull the lower clamping frame 8 outward, so that it moves vertically relative to the upper clamping frame 1, thereby increasing the distance between the upper clamping frame 1 and the lower clamping frame 8. At this time, the elastic mechanism 5 located inside the clamping mechanism 7 is activated, and the damper 501 is stretched, while its outer... The tension spring 502 of the loop also undergoes elastic deformation and stores restoring force; when the upper clamping frame 1 and the lower clamping frame 8 are respectively in suitable positions on both sides of the wall, the personnel release the lower clamping frame 8. Under the action of the elastic potential energy released by the tension spring 502, the lower clamping frame 8 is driven to move closer to the upper clamping frame 1, thereby achieving initial clamping and positioning of the wall and ensuring the stable connection of the bracket in the vertical direction; subsequently, in order to ensure the structural stability after vertical adjustment, the personnel push the connecting seats 405 on both sides, so that they slide along the slide groove 404 at the bottom of the flat rod 401. At the same time, the slider 406 at the top of the connecting seat 405 slides synchronously in the slide groove 404 to achieve guiding positioning. When 405 is moved to the desired height, the fixed insertion rod 407 on one side aligns precisely with the insertion hole 408 on the side wall of the vertical rod 403 on the fixing plate 402, and is inserted into the insertion hole 408 under external force, thus locking the height of the vertical rod 403 and preventing it from sinking or slipping due to force during use. Then, the operator rotates the screw 2 pre-set at the top of the upper frame 1. Since the screw 2 is connected to the nut on the upper frame 1 by a threaded connection, the rotation causes it to advance axially, driving the pressing plate 3 fixed at its end to gradually approach and tightly abut against the wall surface. By adjusting the screw 2's insertion depth, the pressure of the pressing plate 3 on the wall can be precisely controlled, allowing the upper frame 1 to... The lower frame 8 is evenly stressed on both sides of the wall, further enhancing the stability and anti-loosening performance of the clamp. Finally, after the main body of the bracket is fixed, the personnel place the pipeline or lamp support structure of the lighting system into the clamping cavity composed of clamp 1 701 and clamp 2 702, and tighten the connection by two bolts 703 that pass through clamp 1 701 and clamp 2 702. At the same time, a washer 704 is added to the outer ring of the bolt 703 to make the clamping force distribution more even and avoid local stress concentration that may cause the clamp to deform or be damaged. This achieves reliable fixation between the lighting system and the bracket. The entire installation process does not require hot work or welding equipment, is easy to operate, and is suitable for various installation environments.

[0028] This solution effectively solves the technical problems of traditional welded supports, such as complex construction preparation, numerous safety hazards, difficult adjustment, and poor adaptability. Due to the use of an upper clamping frame 1, a lower clamping frame 8, and a mechanical clamping structure with a screw 2 and an extrusion plate 3, on-site welding is eliminated, avoiding the need to transport heavy equipment such as welding machines and oxygen / acetylene cylinders, as well as the cumbersome pre-construction work such as setting up fire blankets and warning zones. This shortens construction preparation time, reduces labor intensity, and eliminates safety risks from open flames, high temperatures, and harmful gases, improving the safety and environmental friendliness of the working environment. By incorporating a damper 501 and a tension spring 502 in the elastic mechanism 5, the clamping process has buffering and self-adjusting capabilities. When clamping the wall, it can automatically compensate for minor dimensional differences, ensuring uniform and stable clamping force and improving connection reliability. The restoring force provided by the tension spring 502 ensures that the lower clamping frame... 8 features an automatic return clamping function, enhancing installation convenience; the design of the horizontal rod 401, vertical rod 403, sliding groove 404, slider 406, connecting seat 405, insertion rod 407, and insertion hole 408 in the adapter mechanism 4 enables stepless adjustment and multi-position locking of the bracket height, allowing flexible adjustment according to different installation height requirements. It also achieves rapid fixing through a plug-in method, overcoming the defect that traditional welded brackets cannot be altered once formed, thus improving the bracket's adaptability to different installation spacings, wall thicknesses, and space heights; the clamping mechanism 7 uses clamp 1 701 and clamp 2 702 to achieve detachable clamping of the lighting conduit via bolts 703 and washers 704, facilitating later maintenance, disassembly, and reuse. This is particularly suitable for scenarios requiring frequent installation and disassembly, such as temporary exhibitions, emergency lighting, and modular buildings, avoiding material waste and increased labor costs caused by re-cutting and welding.

[0029] Example 2:

[0030] Please see Figure 1 - Figure 5 As shown, one end of the tension spring 502 is fixedly connected to the inner wall of the adjacent docking groove 9, and the other end of the tension spring 502 is fixedly connected to the inner wall of the adjacent mounting groove 6.

[0031] One side of the flat rod 401 is fixedly connected to one side of the adjacent upper frame 1, and one side of the lower frame 8 is fixedly connected to one side of the adjacent fixing plate 402.

[0032] Both sides of the bottom of the flat rod 401 are slidably connected to the connecting seat 405, and one side of the connecting seat 405 is fixedly connected to the insertion rod 407. One end of the insertion rod 407 is inserted into the inner cavity of the adjacent insertion hole 408.

[0033] A slider 406 is fixedly connected to the top of the connecting seat 405, and grooves 404 are provided on both sides of the bottom of the flat rod 401. The outer ring of the slider 406 is slidably connected to the inner cavity of the adjacent groove 404.

[0034] The outer ring of bolt 703 is fitted with a washer 704, one end of which is in contact with one side of the adjacent clamp 702.

[0035] As can be seen from the above, by fixing one end of the tension spring 502 to the inner wall of the adjacent docking groove 9 and the other end of the tension spring 502 to the inner wall of the adjacent mounting groove 6, when the operator pulls the lower clamping frame 8 to increase the clamping distance during the working process, the tension spring 502 is stretched and stores elastic potential energy. After being released, its restoring force drives the lower clamping frame 8 to automatically move towards the wall, achieving the effect of making the clamping action more effortless, responding quickly, and ensuring the continuous and stable clamping force. At the same time, it avoids the risk of loosening caused by uneven force applied by the operator, improving the reliability of installation and the convenience of operation. By fixing one side of the flat rod 401 to one side of the adjacent upper clamping frame 1 and one side of the lower clamping frame 8 to the adjacent... The fixed connection on one side of the fixed plate 402 serves as the support base for the upper and lower clamping units during the operation. This fixed connection allows the adapter mechanism 4 to form a stable linkage structure with the upper and lower clamping frames 1 and 8, achieving clear force distribution, strong connection, and resistance to loosening during adjustment and clamping. This ensures the coordination and consistency of vertical adjustment and clamping actions, improving the overall structural stability of the bracket. Connecting seats 405 are slidably connected to both sides of the bottom of the flat rod 401, and a plug rod 407 is fixedly connected to one side of the connecting seat 405. One end of the plug rod 407 is inserted into the inner cavity of the adjacent plug hole 408. During the operation, when the bracket height is adjusted to the correct position... The connecting seat 405 drives the insertion rod 407 to insert into the corresponding height insertion hole 408, achieving mechanical locking of the vertical rod 403. This ensures quick positioning and reliable fixation at different heights, preventing height retraction due to vibration or load changes during use, and enhancing the load-bearing capacity and long-term safety of the bracket. A slider 406 is fixedly connected to the top of the connecting seat 405. Slide grooves 404 are provided on both sides of the bottom of the horizontal rod 401. The outer ring of the slider 406 is slidably connected to the inner cavity of the adjacent slide groove 404. During operation, the slider 406 slides along the length direction within the slide groove 404, providing guidance and support for the horizontal movement of the connecting seat 405, thus enabling the insertion rod to... The 407 maintains a stable, accurate, and unobstructed movement during operation, improving the smoothness of the adjustment process and positioning accuracy, and extending the service life of moving parts. A washer 704 is fitted around the outer ring of the bolt 703, with one end of the washer 704 fitting against one side of the adjacent clamp 702. During operation, when the bolt 703 is tightened to fix clamp 701 and clamp 702, the washer 704 evenly distributes the clamping force applied by the bolt 703, preventing excessive local stress on the clamps and thus avoiding plastic deformation or stress concentration. This also reduces the risk of bolt 703 loosening, improves the uniformity of contact and connection reliability when clamping lighting pipes, and ensures stable clamping performance during long-term use.
