Description

Technical Field

[0001] This utility model relates to the field of lighting engineering, and in particular to an auxiliary device for installing lighting fixtures in lighting engineering. Background Technology

[0002] With the rapid development of urban nightscape lighting projects, a large number of floodlights, wall washers, linear lights, and calligraphy / painting lights are needed to be installed on pole-like structures such as bridges, streetlight poles, trusses, and circular crossarms. Traditional installation methods mainly rely on ordinary clamps and fixed brackets or directly fixing the lights to the pole with expansion bolts, resulting in the following prominent problems during the installation of the lights.

[0003] Ordinary clamps rely solely on the preload of bolts to provide clamping force. Under long-term exposure to wind loads, vibrations, and temperature fluctuations, the bolts are prone to loosening, causing the clamps to loosen, the light fixtures to tilt, sway, or even fall, posing a serious safety hazard.

[0004] Existing clamp-type lamp brackets are mostly rigidly fixed, which cannot automatically unload the impact force in strong winds. The lamps or brackets often suffer fatigue fractures or permanent bending deformations, resulting in high maintenance and replacement costs.

[0005] Traditional brackets are inconvenient to adjust in terms of height, angle, and spacing between lamps, resulting in low installation efficiency and poor adjustment accuracy. They cannot meet the needs of multi-layer staggered layouts or rapid adaptation of different lamps.

[0006] Therefore, it is necessary to further improve the auxiliary devices for installing lighting fixtures in lighting projects. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the existing defects and provide an auxiliary device for installing lighting fixtures in lighting projects. It is stable in installation, has strong anti-loosening ability, can automatically unload impact force in strong winds, and the height and spacing of the lighting fixtures can be quickly adjusted. It has good structural durability and can effectively solve the problems in the background technology.

[0008] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary device for installing lighting fixtures in lighting projects, comprising an installation assembly consisting of a left clamp, a connecting bolt, and a right clamp. The left clamp and the right clamp are symmetrically arranged and are fastened to each other by the connecting bolt. The inner sidewalls of the left clamp and the right clamp are each provided with two circumferentially arranged arc-shaped strips, and a placement cavity is formed between two adjacent arc-shaped strips. A tensioning assembly is provided inside the placement cavity. Mounting columns are fixedly provided on the outer sidewalls of the left clamp and the right clamp. Mounting seats are rotatably mounted on the mounting columns by rotating pins. The mounting seats are rotatably and limitedly connected to the mounting columns by limiting assemblies.

[0009] The mounting base has a vertical through hole, and an adjusting screw is installed in the through hole. The adjusting screw has a first adjusting nut and a second adjusting nut threaded on its upper and lower sides to limit its axial displacement. The lower end of the adjusting screw has a connecting component. The connecting components under the two mounting bases are connected by a suspension component, which is used to suspend the lamp.

[0010] Preferably, the connecting assembly includes a connecting tube and a fixing pin, the connecting tube being sleeved on the lower end of the adjusting screw, and the fixing pin being inserted into the corresponding pin holes of the connecting tube and the adjusting screw.

[0011] Preferably, the suspension assembly includes suspension holes and connecting strips. The suspension holes are arranged in an array along the length of the connecting strips, and the two ends of the connecting strips are fixedly connected to the connecting pipes on both sides.

[0012] Preferably, the tensioning assembly includes an airbag, rubber ribs, and air nozzles. The rubber ribs are circumferentially spaced on the inner side of the airbag, and the air nozzles are sealed to the air inlet of the airbag. The airbag is in contact with the inner walls of the left and right clamps.

[0013] Preferably, the airbag is made of neoprene rubber, with a Kevlar fiber layer sandwiched in the middle of the neoprene rubber layer, and the nozzle is an American-style nozzle.

[0014] Preferably, the limiting component includes a limiting post and a limiting groove. The limiting groove is arc-shaped and is formed on the mounting base. The limiting post is disposed on the mounting post and located within the limiting groove to limit the rotation angle of the mounting base.

[0015] Preferably, the mounting base is provided with symmetrically arranged ribs to increase the load-bearing capacity of the mounting base.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model adopts a composite fixing method of "bolt pre-tightening, annular airbag inflation, and multi-point interlocking of rubber ribs". Even if the bolts are loosened by long-term vibration, the inflated airbag and rubber ribs can still provide strong anti-slip force and anti-rotation torque to prevent the clamp from loosening and falling down, thus solving the safety hazard of traditional clamps inevitably loosening and falling after long-term use.

[0018] The airbag of this invention is placed in a special placement cavity surrounded by arc-shaped strips. When the clamp is tightened, it will not directly squeeze the airbag, thus avoiding local stress concentration and damage to the airbag. The airbag adopts a three-layer composite structure of neoprene rubber and Kevlar fiber, which has excellent ozone aging resistance and puncture resistance. Combined with the inner semi-circular rubber ribs, it greatly improves the coefficient of friction and durability.

[0019] The mounting base of this utility model can rotate freely within a range of ±35°. When the lamp is blown up in strong winds, it can automatically swing to unload the impact force, avoiding rigid breakage of the lamp or bracket, realizing the self-protection function of the structure, and greatly improving the safety and service life under severe weather conditions.

[0020] This invention achieves stepless height adjustment of the adjusting screw through double adjusting nuts. Combined with the suspension holes of the connecting strip array, it can quickly adapt to various lighting fixtures with different heights and different mounting hole spacings. It supports quick installation by a single person and multi-layer staggered arrangement, improving installation efficiency. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] An auxiliary device for installing lighting fixtures in lighting projects is applicable to the rapid installation of floodlights, calligraphy and painting lights, linear lights, and other lighting fixtures on circular crossarms, bridge circular tubes, or truss circular tubes.

[0030] like Figure 1 and Figure 2 As shown, the installation assembly 1 consists of a left clamp 101, a right clamp 103, and multiple sets of connecting bolts 102. The left clamp 101 and the right clamp 103 are symmetrical and are fastened together by connecting bolts 102 made of stainless steel or carbon steel and matching nuts and spring washers to form a circular clamp that can be fixed on the horizontal support rod.

[0031] The left clamp 101 and right clamp 103 are made of 6mm thick Q235B steel plate or 304 stainless steel plate, formed by CNC bending, and the surface is hot-dip galvanized or sprayed with outdoor fluorocarbon paint to ensure an outdoor corrosion resistance service life of more than 10 years.

[0032] Two circumferentially extending arc-shaped strips 6 are welded to the inner walls of the left clamp 101 and the right clamp 103. The four arc-shaped strips 6 form a complete annular placement cavity to accommodate the tensioning component 8.

[0033] The arc-shaped strip 6 serves both to axially position and radially limit the tensioning component 8, and also acts as a support rib when the clamp is tightened, preventing the installation component 1 from directly squeezing the airbag and causing local stress concentration.

[0034] The tensioning assembly 8 includes an annular airbag 801, rubber ribs 802, and an air nozzle 803. The airbag 801 is placed inside the placement cavity, with its outer surface fitting against the inner wall of the clamp and its inner surface facing the clamped rod. The airbag 801 adopts a three-layer composite structure, with the inner and outer layers being 2mm thick neoprene rubber and a layer of high-strength Kevlar fiber woven mesh sandwiched in the middle, exhibiting excellent ozone aging resistance and improving puncture resistance.

[0035] Twelve semi-circular rubber ribs 802 are evenly bonded to the inner circumference of the airbag 801. These rubber ribs 802 enhance friction, prevent slippage, and strengthen structural durability, extending service life. The air nozzle 803 is a standard American-style nozzle, sealed and installed on the outside of the airbag, allowing for inflation of the airbag 801 using a regular air pump or electric air pump.

[0036] During installation, first tighten the connecting bolts 102 to make the mounting component 1 fit against the rod body. Then, inflate the airbag 801 through the air nozzle 803. The expansion of the airbag 801 pushes the rubber ribs 802 tightly against the surface of the rod body, forming a multi-point high-friction engagement. Inflation is stopped once the mounting component 1 is firmly fixed. At this point, even if the bolts loosen due to long-term vibration, the airbag and rubber ribs can still provide anti-slip force and anti-torque.

[0037] Two mounting posts 3 are symmetrically welded to the outer walls of the left clamp 101 and the right clamp 103. Each mounting post 3 is hinged to a mounting seat 5 by an M16 stainless steel transverse rotating pin, allowing the mounting seat 5 to rotate on the mounting post 3.

[0038] To prevent excessive rotation angle, an arc-shaped limiting groove 1102 is provided on the side of the mounting base 5, and a matching limiting post 1101 is fixed on the mounting post 3. The limiting post 1101 slides within the limiting groove 1102, thereby limiting the rotation angle to within ±35°. After installation, the lamp maintains the set angle by its own weight, without the need for an additional locking mechanism, making operation simple. In case of severe weather, due to the large force-bearing area of ​​the lamp, when it is blown up, it can drive the mounting base 5 to rotate within ±35°, thereby effectively unloading the impact force and preventing rigid fracture or permanent deformation of the lamp or mounting base, achieving a self-protection function of the structure.

[0039] A vertically penetrating circular through hole is formed in the center of the mounting base 5, through which an adjusting screw 2 is inserted. The adjusting screw 2 is a stainless steel trapezoidal threaded rod, with a first adjusting nut 4 and a second adjusting nut 9 (both anti-loosening nuts) screwed onto its upper and lower sides respectively. By simultaneously adjusting the positions of the first adjusting nut 4 and the second adjusting nut 9 on the adjusting screw 2, the height of the adjusting screw 2 within the mounting base 5 can be adjusted. When the first adjusting nut 4 and the second adjusting nut 9 are simultaneously tightened to fit snugly against the mounting base 5, the mounting base 5 can be clamped and fixed, meeting the needs of different lamp installation heights or staggered arrangement of multiple lamps.

[0040] The lower end of the adjusting screw 2 is connected to the suspension assembly 10 via the connecting assembly 7. The connecting assembly 7 includes a connecting tube 701 and a fixing pin 702. After the connecting tube 701 is sleeved on the lower end of the adjusting screw 2, a stainless steel fixing pin 702 is inserted laterally into the corresponding pin hole to achieve quick locking. This structure can withstand tension and allow small-amplitude swinging. Installation and disassembly only take a few seconds.

[0041] The connecting pipes 701 on both sides are connected laterally via the suspension assembly 10. The suspension assembly 10 consists of connecting strips 1002, which are made of square steel or aluminum alloy profiles of equivalent strength, with a set of suspension holes 1001 every 50mm along the length of the surface. The two ends of the connecting strips 1002 are fixed to the connecting pipes 701 on both sides by welding. A suitable suspension hole 1001 is selected according to the actual installation hole spacing of the lamp, and the lamp hanging lugs or hook brackets are directly hung using M12 stainless steel bolts, thus adjusting the lamp installation spacing.

[0042] To improve load-bearing capacity, 10mm thick triangular ribs 12 are symmetrically welded on both sides of the mounting base 5, forming a stable triangular support structure with the mounting base body and mounting column 3, which meets the installation requirements of high-power floodlights and long strip lights.

[0043] The working principle and usage method of this utility model are as follows: the left clamp 101 and the right clamp 103 are closed on the target pole body, the connecting bolts 102 are tightened for initial fixation, and the air pump or electric air pump is used to inflate the air bag 801 through the air nozzle 803. The air bag 801 expands and pushes the rubber ribs 802 to press tightly against the surface of the pole body, forming a multi-point high friction engagement, until the installation component 1 is firmly fixed and the inflation is stopped.

[0044] According to the height requirements of the lamp, adjust the two adjusting screws 2 to the appropriate position, tighten the first adjusting nut 4 and the second adjusting nut 9 until they fit the mounting base 5, and the mounting base 5 can be clamped and secured.

[0045] Choose the appropriate hanging hole 1001 on the connecting strip 1002 according to the lamp selection, and hang the lamp on the connecting strip 1002 to assist in the installation of the lamp;

[0046] After installation, the lamp maintains a vertical angle by its own weight. In case of severe weather, due to the large force-bearing area of ​​the lamp, when it is blown, it can drive the mounting base 5 to rotate within ±35° along the limiting post 1101, thereby effectively unloading the impact force and preventing the lamp or mounting base from rigidly breaking or deforming, thus realizing the self-protection function of the structure.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
