AI Technical Summary
The existing lamp holders have low reliability, inconvenient operation for adjusting angles, and relying on the friction of bolts and nuts to easily fail, resulting in loose or sliding of the lower holders.
The combination of upper bracket, lower bracket, tooth-shaped top block and locking screw is adopted to adjust angle and lock through tooth engagement. Instead of friction locking, the angle can be adjusted by using a one-handed locking screw.
It improves the reliability of the bracket and the operation convenience of adjusting the angle. The locking effectiveness of the tooth engagement method is higher than that of the friction locking, avoiding locking failure caused by frictional decline.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of lamp mounting brackets, in particular to an LED lamp mounting bracket. Background Art
[0002] In the prior art, the bracket of the lamp is installed as follows Figure 1-3 As shown, the lower bracket 2 is fastened to the upper bracket 1 by bolts 9 and nuts 10. When the bolts 9 and nuts 10 are loosened, the lower bracket 2 can freely adjust the installation angle. After adjusting the appropriate angle, tighten the bolts 9 and nuts 10, and the bracket is fastened.
[0003] The disadvantages of this method are: low reliability, the lower bracket 2 is fastened to the upper bracket 1 by the friction force generated by the locking of the bolts 9 and nuts 10. When the locking force decreases, the lower bracket 2 is at risk of loosening or sliding; the on-site adjustment of the angle of the lower bracket 2 is not very convenient, the lower bracket 2 is fastened to the upper bracket 1 by the friction force generated by the locking of the bolts 9 and nuts 10. When the installation angle of the lower bracket 2 needs to be adjusted, the bolts 9 and nuts 10 need to be clamped with a wrench at the same time, and tightened or loosened to adjust the lower bracket 2. Summary of the invention
[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an LED lamp mounting bracket.
[0005] To solve the above problems, the utility model adopts the following technical solutions.
[0006] A LED lamp mounting bracket comprises an upper bracket, a lower bracket, a toothed top block and a locking screw, wherein the bottom of the lower bracket can be connected to the lamp, a bracket shaft is fastened in the upper bracket and the bracket shaft is rotatably arranged in the lower bracket, a bracket cover is arranged on the lower bracket, a first tooth is arranged on the side wall of the bracket shaft, a second tooth that can be engaged and fixed with the first tooth is arranged on the toothed top block, and an end of the locking screw is connected to the toothed top block so as to be able to move back and forth inside the lower bracket to enable the toothed top block to engage, fix or disengage with the bracket shaft.
[0007] As a further improvement of the present invention, a block capable of being inserted into the lamp is provided at the bottom of the lower bracket.
[0008] Beneficial effects of the utility model
[0009] Compared with the prior art, the advantages of the present invention are:
[0010] The upper and lower brackets can adjust the installation angles by tooth meshing and loosening, replacing the existing method of locking the brackets by the friction generated by screw locking. The tooth meshing method is much more reliable than the friction method. As long as the meshing teeth are not damaged, the locking is always effective. However, the friction locking method will cause the friction to decay over time, resulting in locking failure.
[0011] When adjusting the angle of the bracket, it only needs to loosen or tighten a screw with one hand, while the existing solution requires two hands to tighten or loosen the bolts and nuts at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model; it is obvious that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the utility model without making creative work are within the scope of protection of the utility model.
[0021] See also Figures 4 to 8A LED lamp mounting bracket comprises an upper bracket 1, a lower bracket 2, a toothed top block 3 and a locking screw 4, the bottom of the lower bracket 2 can be connected to the lamp 5, a bracket shaft 6 is fastened in the upper bracket 1 and the bracket shaft 6 is rotatably arranged in the lower bracket 2, a bracket cover 7 is arranged on the lower bracket 2, a first tooth is arranged on the side wall of the bracket shaft 6, and a second tooth that can be engaged and fixed with the first tooth is arranged on the toothed top block 3, and the end of the locking screw 4 is connected to the toothed top block 3 so that it can move back and forth inside the lower bracket 2 to make the toothed top block 3 engage, fix or disengage with the bracket shaft 6.
[0022] Furthermore, a block 8 capable of being inserted into the lamp 5 is disposed at the bottom of the lower bracket 2 .
[0023] First, the bracket shaft 6 with the first teeth is assembled with the upper bracket 1 in a tight fit, and the bracket cover 7 is equipped with a toothed top block 3 with the second teeth. By tightening or loosening the locking screw 4, the toothed top block 3 and the bracket shaft 6 can be engaged or disengaged. When the bracket angle needs to be adjusted, the locking screw 4 is loosened, and the toothed top block 3 is disengaged from the bracket shaft 6. The upper bracket 1 can freely adjust the installation angle. When the angle is adjusted, the bracket locking screw 4 is locked, the toothed top block 3 is engaged and locked with the bracket shaft 6, and the upper bracket 1 is naturally locked. It is simple to adjust the bracket installation angle on site. You only need to loosen the locking screw 4 with an Allen wrench, adjust the upper bracket 1 to a suitable angle, and then lock it.
[0024] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
