Description

Technical Field

[0001] The utility model relates to the technical field of lighting brackets, in particular to an adjustable lighting bracket. Background Technique

[0002] A lighting bracket is a bracket used for supporting the installation of a lighting lamp. During the home decoration construction process, since the lighting lamp is not installed in the house during the renovation process, energy-saving bulbs are often used as lighting tools during the decoration period for decoration lighting. However, the lighting range of energy-saving bulbs is limited. For high-corner areas, when the lighting is insufficient, it is difficult for construction workers to carry out effective construction on the scaffolding. To increase the brightness, construction workers will choose to install a lighting lamp with a lighting bracket on the upright column of the scaffolding for temporary lighting to improve the lighting effect, thus facilitating the work of construction workers.

[0003] Currently, during the installation process of the lighting bracket and the scaffolding upright column, screws or bolts and other fasteners are often used for locking and fixing. That is, construction workers will choose to drill corresponding holes on both the lighting bracket and the scaffolding upright column, and then after aligning the preset holes on both sides, install and fix them with screws or bolts and other fasteners.

[0004] However, when construction workers drill holes on the scaffolding upright column and the lighting bracket, sometimes due to carelessness, small deviations will occur, resulting in small position deviations when aligning the preset holes on both sides. Re-drilling holes is a waste of time, and when the deviation is too small and the distance is too close, re-drilling holes will penetrate through the originally preset holes, making the installation of screws or bolts not sufficiently stable, resulting in insufficiently firm installation. Moreover, during the use of the lighting lamp installed on the lighting bracket, its angle is fixed and not easy to adjust, and the use effect is poor. Therefore, there is an urgent need to improve the technology of the lighting bracket structure to improve this equipment.

[0005] Therefore, the utility model proposes an adjustable lighting bracket to solve the above problems. Content of the Utility Model

[0027] Embodiment 1: Please refer to Figures 1 to 6 , the present utility model provides a technical solution: an adjustable lighting bracket, the adjustable lighting bracket includes: a support frame 1, a moving screw 2 is arranged inside the support frame 1, a moving plate 3 is screwed on the surface of the moving screw 2, one end of the moving plate 3 is provided with a mounting plate 4, a positioning tube 5 is arranged on the surface of the support frame 1, a support plate 6 is arranged inside the positioning tube 5, and a positioning rod 7 is arranged on the surface of the support plate 6;

[0028] A rotating plate 8, a limiting groove 9 is formed on the surface of the rotating plate 8, a fixing plate 10 is arranged on the side surface of the rotating plate 8, a positioning frame 11 is arranged at one end of the fixing plate 10, a support screw 12 is arranged inside the positioning frame 11, a bracket 13 is fixedly connected to the surface of the support screw 12, and a lighting lamp 14 is arranged at one end of the bracket 13;

[0029] First, the rotation of the moving screw 2 can displace the moving plate 3, thereby adjusting the position of the mounting plate 4, facilitating the alignment of the through holes opened on the side surface of the mounting plate 4 with the through holes opened on the scaffolding for convenient fixing with bolts. Then, the positioning rod 7 can be pulled out from the limiting groove 9, thereby enabling the lighting lamp 14 to rotate in angle. The cooperation of the positioning nut 21 and the support screw 12 facilitates the up-and-down rotation adjustment of the lighting lamp 14, which is relatively convenient.

[0030] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the alignment of the mounting plate 4 with the holes opened on the scaffolding, a moving screw 2 is provided. Two sets of placement grooves 15 are formed on the surface of the support frame 1, and the two sets of placement grooves 15 are symmetrically distributed with respect to the support frame 1. A bearing 16 is arranged at the end face of the placement groove 15, and one end of the moving screw 2 is fixedly connected to the inner ring surface of the bearing 16;

[0031] During use, the moving screw 2 can be rotated in cooperation with the bearing 16, thereby enabling the moving plate 3 to displace inside the placement groove 15. The arrangement of the placement groove 15 also avoids the problem that the moving plate 3 rotates when the moving screw 2 rotates. Then, the mounting plate 4 can be driven to displace, facilitating the alignment of the holes opened on the surface of the mounting plate 4 with the holes opened on the scaffolding for convenient subsequent installation.

[0032] A support screw rod 12 is provided to facilitate the up-and-down rotation angle setting of the illuminating lamp 14. The positioning frame 11 is integrally in a "C"-shaped plate structure. A second bearing 20 is provided on the inner side surface of the positioning frame 11. One end of the support screw rod 12 is fixedly connected to the inner ring surface of the second bearing 20. A positioning nut 21 is screwed on the surface of the support screw rod 12. The bracket 13 is fixedly connected to the surface of the support screw rod 12.

[0033] When it is necessary to adjust the up-and-down rotation angle of the illuminating lamp 14, first loosen the positioning nut 21, and then the support screw rod 12 can rotate by using the setting of the second bearing 20, so as to drive the illuminating lamp 14 to rotate. After rotating to the appropriate position, tighten the positioning nut 21 to avoid the problem that the illuminating lamp 14 continues to rotate after the rotation angle.

[0034] Embodiment 3: On the basis of Embodiment 2, a rotating plate 8 is provided to facilitate the rotation of the illuminating lamp 14. The positioning tube 5 is fixedly connected to the surface of the support frame 1. A lifting port 17 is opened on the side surface of the positioning tube 5. A limiting spring 18 is arranged inside the positioning tube 5. The support plate 6 is inserted into the lifting port 17. The support plate 6 can move up and down in the lifting port 17. One end of the limiting spring 18 is fixedly connected to the end surface of the positioning tube 5, and the other end of the limiting spring 18 is fixedly connected to the bottom of the support plate 6. A limiting bearing 19 is sleeved on the surface of the positioning tube 5. The rotating plate 8 is fixedly connected to the outer ring surface of the limiting bearing 19. A plurality of groups of limiting grooves 9 are provided. The plurality of groups of limiting grooves 9 are regularly arranged in a circular shape around the center point of the surface of the rotating plate 8. One end of the positioning rod 7 can be inserted into the limiting groove 9.

[0035] When in use, when it is necessary to rotate the illuminating lamp 14, first pull the support plate 6 to disengage the positioning rod 7 from the limiting groove 9, so that the rotating plate 8 can be rotated by using the setting of the limiting bearing 19. After rotating to the appropriate position, release the support plate 6 to enable the support plate 6 to reset by the elastic force of the limiting spring 18 so that the positioning rod 7 is inserted into other groups of limiting grooves 9, thereby avoiding the continuous rotation of the rotating plate 8. The setting of the lifting port 17 also avoids the problem of the rotation of the support plate 6.

[0036] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
