Problems solved by technology

However, after the device is used for a long time, the limit ring will become loose, and friction noise will appear when the limit ring is loose and then rotated.
[0004] This type of shaft has a simple structure, but its service life is not long, and there will be friction noise during rotation. If necessary, lubricants should be added to eliminate noise, which will increase labor costs and reduce the high-end performance of the product.

Embodiment 1

[0027] A shaft structure is provided in this embodiment, such as Figure 1-2 As shown, it includes an upper rod fixed shaft 1, a lower rod fixed shaft 2, a tightening screw 3 passing through the upper rod fixed shaft 1 and the lower rod fixed shaft 2 in turn, an internally threaded shaft 4 cooperating with the tightened screw 3 and locking pin 5;

[0028] At least one end of the upper rod fixed shaft 1 or the lower rod fixed shaft 2 is located in the lower rod fixed shaft 2 or the upper rod fixed shaft 1, and the upper rod fixed shaft 1 and the lower rod fixed shaft 2 can rotate with each other without axial displacement change , the end of the lower rod fixed shaft 2 away from the tightening screw 3 is also provided with a locking groove 21 that matches the locking pin 5; the upper rod fixed shaft 1 or the lower rod fixed shaft 2 is provided with a spring 6, and the lower rod is fixed A rotation groove 7 is provided on the side wall of the shaft 2; one end of the spring 6 is...

Embodiment 2

[0031] A shaft structure is provided in this embodiment, such as Figure 1-2 As shown, it includes an upper rod fixed shaft 1, a lower rod fixed shaft 2, a tightening screw 3 passing through the upper rod fixed shaft 1 and the lower rod fixed shaft 2 in turn, an internally threaded shaft 4 cooperating with the tightened screw 3 and Locking pin 5.

[0032] Such as Figure 3-4 As shown, the side walls of the upper rod fixed shaft 1 and the lower rod fixed shaft 2 are provided with a rotation groove 7, and one end of the upper rod fixed shaft 1 is located in the lower rod fixed shaft 2, and the upper rod fixed shaft 1 is fixed with the lower rod The shafts 2 are mutually rotatable and coaxial, and the other end of the upper rod fixed shaft 1 is located outside the lower rod fixed shaft 2; the same side of the upper rod fixed shaft 1 and the lower rod fixed shaft 2 are equipped with Tighten the through hole of the screw 3, and tighten the screw 3 through one end of the upper rod...

Embodiment 3

[0041] The difference with embodiment 2 in this embodiment is:

[0042] The upper rod fixed shaft 1 is located in the lower rod fixed shaft 2, and the upper rod fixed shaft 1 and the lower rod fixed shaft 2 are provided with a rotation groove 7, the spring 6 is located in the upper rod fixed shaft 1, and one end of the spring 6 is fixed to the upper rod The shaft 1 is fixed, and the other end is fixed with the locking pin 5.

[0043] Other structures are the same as those in Embodiment 2, and will not be repeated here.

Abstract

Provided is a rotary shaft structure, comprising an upper-rod fixing shaft (1), a lower-rod fixing shaft (2), a tightening screw (3), and an interfitting internally threaded shaft (4) and locking pin (5); at least one end of the upper- and lower-rod fixing shafts is located inside the lower- and upper-rod fixing shafts, respectively, and the upper-rod fixing shaft (1) and lower-rod fixing shaft (2) may rotate with respect to each other; the lower-rod fixing shaft (2) end away from the tightening screw (3) is also provided with a lock groove (21) fitting the locking pin (5); the upper- and lower-rod fixing shafts are internally provided with a spring (6), and the side wall of the lower-rod fixing shaft (2) is provided with a rotation groove (7); the two ends of the spring (6) are fixedly connected to the upper-rod fixing shaft (1) and the locking pin (5), respectively. The rotary shaft structure is such that when a user is adjusting the angle between the upper rod and lower rod of a lamp, one need only lightly press or raise the upper rod in order to adjust the rotation of a bulky lamp; at the same time, the user has a very good tactile experience when making adjustments.

Description

technical field [0001] The invention relates to the technical field of LED lamp lighting, in particular to a rotating shaft structure for LED lamp rotation. Background technique [0002] Due to the continuous development and innovation of LED technology, people's pursuit of novelty and high-end household lighting products is also getting higher and higher. At present, the common rotatable LED desk lamps, arm lamps, floor lamps, corner lamps, etc., all of the above-mentioned lamps use the rotating shaft structure, but the rotating shaft structure in the prior art is complicated, and most of them are fixed in the form, requiring specific tools to use. It can be installed only after the body is deformed. The process is more complicated and the damage to the body is greater. [0003] Chinese patent document CN 104791371A discloses a new rotating shaft structure for LED lamps, which includes a rotating shaft, a rotating member, a rotating shaft core and a limit ring. The shaft ...
