Abstract
Description
Technical Field
[0001] The utility model belongs to the field of LED lamps, and particularly relates to a rotating shaft structure of an LED lamp. Background Art
[0002] In the prior art, when the lamp head is set to be rotatable, a rotating shaft structure is generally provided. However, in the prior art, the rotating shaft structure of the lamp generally does not have a limiting structure or only has a clamping structure (such as a threaded structure for abutting) to fix the rotatable lamp head. However, the former is likely to cause the fixing angle of the lamp head to be unstable and the irradiation angle to shift easily due to accidental contact by the user. The latter may cause the loosening of the clamping structure during the use of the lamp, resulting in the same problem as the former. Therefore, a limiting mechanism needs to be provided for the rotating shaft structure of the lamp to fix the irradiation angle of the lamp head. At the same time, in order to enable the lamp head to be adjusted at multiple angles, multiple limiting structures are required to ensure the multi-angle adjustment of the lamp head. And because of the need for a limiting structure that can be adjusted at multiple angles, the structure of the entire lamp will be more complex. Summary of the Utility Model
[0003] The purpose of the utility model is to solve the problem that in the prior art, an LED lamp requires a limiting structure that can be adjusted at multiple angles, but this will lead to a more complex limiting structure.
[0004] To achieve the above purpose, the utility model provides the following technical solution: a rotating shaft structure of an LED lamp, including a lamp shaft, an upper lamp rod and a lower lamp rod through which the lamp shaft passes. A bearing seat and a bearing are arranged between the upper lamp rod and the lower lamp rod. The upper lamp rod and the bearing seat are relatively fixed. The lamp shaft is arranged in the bearing seat and the bearing. The lower lamp rod is relatively fixed to the lamp shaft. The upper lamp rod can rotate relative to the lamp shaft. A limiting piece with a plurality of grooves is arranged between the lamp shaft and the bearing seat. The limiting piece is clamped on the lamp shaft and is relatively fixed to the lamp shaft. A plurality of elastic pieces are arranged through the bearing seat. The elastic pieces can pass through the bearing seat and fall into the grooves of the limiting piece to limit the rotation between the upper lamp rod and the lamp shaft. The number of the elastic pieces is the same as the number of the grooves of the limiting piece.
[0005] Preferably, the elastic piece is a spring pin inserted into a spring, and the spring pin has an arc-shaped head structure that matches the groove.
[0006] Preferably, the upper lamp rod is relatively fixed to the bearing seat through a threaded structure.
[0007] Preferably, a rotating shaft structure base is arranged in the lower lamp rod. The lamp shaft is arranged in the rotating shaft structure base and connects the bearing seat and the rotating shaft structure base. The bearing seat can rotate relative to the rotating shaft structure base.
[0008] Preferably, the lamp shaft and the lower lamp rod are clamped by a clamping piece to keep the relative fixation of the two.
[0009] Preferably, the lower lamp rod is relatively fixed to the base of the rotating shaft structure through a threaded structure.
[0010] The utility model has the following beneficial effects: The utility model provides a rotating shaft structure of an LED lamp, which limits the rotation of the lamp through a simple limiting piece with a groove and a corresponding elastic member, and at the same time can flexibly set the number of grooves according to the rotation angle to be adjusted, ensuring that the rotation angle of the lamp head can be adjusted more precisely without setting a complex structure.

[0020] Embodiment
[0021] The following are only the preferred embodiments of the present utility model. The protection scope of the present utility model is not limited to the following embodiments. All technical solutions falling within the idea of the present utility model belong to the protection scope of the present utility model.
[0022] Refer to the attached drawings of the specificationFigure 1-2 , a rotating shaft structure of an LED lamp, comprising a lamp shaft 2, an upper lamp rod 1 and a lower lamp rod 10 through which the lamp shaft passes. A bearing seat 7 and a bearing 8 are arranged between the upper lamp rod 1 and the lower lamp rod 10. The lamp shaft 2 is arranged in the bearing seat 7 and the bearing 8. A rotating shaft structure base 9 is arranged in the lower lamp rod. The lamp shaft 2 is also arranged in the rotating shaft structure base 9 and is connected to the bearing seat 7 and the rotating shaft structure base 9. The bearing seat 7 can rotate relative to the rotating shaft structure base 9. The upper lamp rod 1 is relatively fixed to the bearing seat 7 through a threaded structure. The lower lamp rod 10 is relatively fixed to the rotating shaft structure base 9 through a threaded structure. Therefore, when the upper lamp rod 1 and the lower lamp rod 10 rotate relative to each other, the bearing seat 7 and the rotating shaft structure base 9 also rotate relative to each other. The lamp shaft 2 and the lower lamp rod 10 are clamped by a clamping piece 11 to keep the relative fixation of the two.
[0023] The upper lamp rod 1 can rotate relative to the lamp shaft 2. A limiting piece 4 with a plurality of grooves is arranged between the lamp shaft 2 and the bearing seat 7. The limiting piece 4 is clamped on the lamp shaft 2 and is relatively fixed to the lamp shaft 2. A plurality of spring pins 5 passing through springs 6 are arranged on the bearing seat 7 (the bearing seat 7 is correspondingly provided with a receiving hole for receiving the spring pins 5. When the spring is in a relaxed state, the spring pins 5 will protrude from the bearing seat 7 and fall into the grooves. When the upper lamp rod 1 rotates or the rotating upper lamp rod rotates, at this time, the rotational force is decomposed into a downward pressure for pressing the spring pins 5 by the grooves, and the spring pins 5 slide out of the grooves. Under the action of the spring 6, the spring pins retract into the receiving holes to ensure the rotation of the upper lamp rod 1. At this time, the spring pins 5 abut against the planar structure of the limiting piece 4. When the upper lamp rod is adjusted to the next adjustment angle, that is, the next groove, the spring pins 5 will protrude from the bearing seat 7 and fall into the groove under the action of the spring 6 to complete the adjustment of the rotation angle of the LED. At this time, the spring pins 5 will strike the limiting piece to realize the sound feedback). Therefore, the spring pins 5 have an arc-shaped head structure matching the grooves. The spring pins 5 can protrude from the bearing seat and fall into the grooves of the limiting piece 4 to limit the rotation between the upper lamp rod 1 and the lamp shaft 2. The number of the spring pins 5 is the same as the number of the grooves of the limiting piece 4. In the embodiment of the present invention, the number of the grooves of the limiting piece and the number of the spring pins are both four.
[0024] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those who are familiar with this technology to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit and essence of the present invention should be covered within the protection scope of the present invention.
