Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a steel structure lighting bracket with adjustable angle. Background Art

[0002] During the construction process, lamps are an indispensable part of the construction. In traditional steel cylindrical structural beam buildings, lamps provide lighting for the interior of the building, which is convenient for construction in dim light. The lighting method of this type of building is often to suspend the lamps vertically on the top cylindrical structural beam.

[0003] However, practice has shown that the lighting method in traditional steel cylindrical structural beam buildings has the following problems: the lamps are suspended vertically downward, so the light in the local area below the lamps is too strong, which leads to glare, while the light in the corners of the building or the local areas blocked by the cylindrical structural beams is dim, resulting in lighting blind spots. Both glare and dim light will affect the workers who are working, thereby reducing construction efficiency.

[0004] Therefore, it is necessary to invent a steel structure lighting bracket with adjustable angle to solve the above problems. Utility Model Content

[0008] Furthermore, the end of the active rotating shaft is arranged in a hexagonal prism shape, a rotating handle is sleeved on the end of the active rotating shaft, and a hexagonal opening is formed at the end of the rotating handle.

[0010] Furthermore, the driving shaft and the driven shaft are integrally fixed with convex strips, the inner side walls of the driving gear and the driven gear are provided with grooves matching the positions of the convex strips, and the convex strips are embedded in the matching grooves.

DETAILED DESCRIPTION

[0021] An angle-adjustable steel structure lighting bracket, as shown in the attached Figure 1 -Attached Figure 3 As shown, it includes a cylindrical structural beam 1, and also includes a fixed ring 2 sleeved on the structural beam 1, the fixed ring 2 is provided with an adjusting notch 3, and two connecting plates 4 fixed integrally with the fixed ring 2 are respectively arranged at both ends of the adjusting notch 3, the two connecting plates 4 are vertically and parallelly arranged, and the upper parts of the two connecting plates 4 are commonly penetrated by a fixing bolt 5, and the ends of the fixing bolts 5 are screwed with a fastening nut 6 close to the surface of the connecting plate 4, and the middle parts of the two connecting plates 4 are commonly rotatably supported by a driving shaft 7, and the driving shaft 7 is fixedly equipped with a driving gear 8 located between the two connecting plates 4, and the lower parts of the two connecting plates 4 are commonly rotatably supported by a driven shaft 9, and the driven shaft 9 is fixedly equipped with a driven gear 10 meshing with the driving gear 8, and a U-shaped bracket 11 is fixed on the driven shaft 9, and a lampshade 12 is fixedly connected to the bottom end of the U-shaped bracket 11.

[0022] The utility model uses a fixed ring 2, two connecting plates 4, fixing bolts 5 and fastening nuts 6 to connect the lampshade 12 to the cylindrical structural beam 1, making full use of the existing structure of the construction site. The two connecting plates 4 provide installation space for the driving gear 8 and the driven gear 10. When the driving shaft 7 rotates, the driving gear 8 thereon is driven to rotate, and the driving gear 8 drives the driven gear 10 to rotate through the meshing relationship. When the driven gear 10 rotates, the driven shaft 9 and the U-shaped bracket 11 fixedly connected thereto are driven to rotate synchronously, thereby driving the U-shaped bracket 1 The lampshade 12 at the bottom of the lampshade 1 rotates, and the lamp is installed in the lampshade 12. The rotation of the lampshade 12 realizes the angle adjustment of the lamp, and the range of the angle adjustment can be specifically determined according to the darkness of the actual site, so as to illuminate the corners of the building or the local areas blocked by the cylindrical structural beams, avoid the occurrence of lighting blind spots, and disperse the light to a certain extent, reduce the generation of glare, and thus reduce the impact on the operators, thus overcoming the problem that the lighting of the lamps in the existing steel structure cylindrical structural beam buildings has dim light in some areas or too strong light in some areas.

[0023] As attached Figure 4 , Attachment Figure 5As shown, the end of the active rotating shaft 7 is in a hexagonal prism shape, a rotating handle 13 is sleeved on the end of the active rotating shaft 7, and a hexagonal opening 14 is formed at the end of the rotating handle 13.

[0024] The structural setting of the rotating handle 13 realizes the rotation of the active rotating shaft 7, and the rotating handle 13 can be removed after adjusting the angle of the lamp, so as to facilitate turnover and use.

[0025] As attached Figure 4 As shown, the outer surface of the connecting plate 4 is fixedly connected to an angle indicator 15 sleeved on the driven shaft 9, and the surface of the angle indicator 15 is engraved with an angle value. The driven shaft 9 is fixedly provided with an indicator ring 16 that matches the position of the angle indicator 15, and a pointer 17 is fixed on the indicator ring 16.

[0026] When the driven shaft 9 rotates, the indicator ring 16 also rotates with the driven shaft 9 and drives the pointer 17 to rotate. When the angle adjustment of the lamp is completed, the pointer 17 stops rotating. The position pointed by the pointer 17 on the angle indicator 15 is the value of the adjusted angle of the lampshade 12.

[0027] As attached Figure 5 As shown, the driving shaft 7 and the driven shaft 9 are integrally fixed with convex strips 18, and the inner side walls of the driving gear 8 and the driven gear 10 are provided with grooves 19 that match the position of the convex strips 18, and the convex strips 18 are embedded in the matching grooves 19.

[0028] The structural design of the convex strip 18 and the concave groove 19 realizes the fixed connection between the driving gear 8 and the driving rotating shaft 7 , and the fixed connection between the driven gear 10 and the driven rotating shaft 9 .

[0029] As attached Figure 4 As shown, two ends of the driven gear 10 are respectively provided with two collars 20 fixedly sleeved on the driven rotating shaft 9 , and two ends of the U-shaped bracket 11 are respectively fixedly connected to the two collars 20 .

[0030] The two collars 20 can rotate synchronously with the driven shaft 9, and at the same time drive the U-shaped bracket 11 to rotate synchronously, and then drive the lampshade 12 to rotate, so as to facilitate angle adjustment.

[0031] As attached Figure 4 As shown, a through hole 1 is formed through the side wall of the collar 20, a through hole 2 is formed through the driven shaft 9 and the position of the through hole 1 matches that of the through hole 1, and a pin 21 is penetrated through both the through hole 1 and the through hole 2.

[0032] The structural design of the through hole 1, the through hole 2 and the pin shaft 21 strengthens the fixed connection between the collar 20 and the driven shaft 9, making the overall structure more stable.

[0033] As attached Figure 4As shown, a locking rod 22 is commonly provided on the two connecting plates 4 , and the locking rod 22 passes between two tooth grooves of the driving gear 8 .

[0034] The structural design of the locking rod 22 can lock the driving gear 8 after the angle adjustment is completed, thereby avoiding the problem that the rotation angle of the lampshade 12 changes due to the rotation of the driving gear 8.

[0035] When in use, the operator first sets the fixing ring 2 on the structural beam 1 so that the two connecting plates 4 are vertically downward, and then the operator tightens the fastening nut 6 so that the fixing ring 2 is tightly attached to the structural beam 1 to prevent the fixing ring 2 from sliding, and then installs the rotating handle 13 on the end of the active shaft 7, manually rotates the rotating handle 13, the active shaft 7 starts to rotate, and drives the active gear 8 to rotate, through the meshing relationship between the active gear 8 and the driven gear 10, the driven gear 10 also rotates accordingly, and the driven gear 10 drives the driven shaft 9 and the U-shaped bracket 11 to rotate synchronously, and the U-shaped bracket 11 drives the lampshade 12 at its bottom end to rotate, thereby realizing the adjustment of the rotation angle of the lampshade 12, and finally after the adjustment is completed, the locking rod 22 is inserted between two of the tooth grooves of the active gear 8 to lock the active gear 8 to prevent the active gear 8 from rotating, and the rotating handle 13 can be removed at this time, and the angle adjustment of the next steel structure lighting bracket can be repeated.

[0036] During the specific implementation process, the rotation range of the rotating handle 13 can be adjusted according to the layout of the steel structure cylindrical structural beam building. During the rotation of the rotating handle 13, the staff can determine the specific rotation angle by observing the value of the angle indicator 15 pointed by the pointer 17, which is convenient for the reference of the operating personnel.
