[0031] The ball head angle adjustment mechanism of the projection lamp provided by this utility model uses the ball head body 204 and the spherical cavity 206 to form a ball hinge structure, which allows the protective shell 101 to swing in multiple directions. By tightening the fastening bolt 208 and the limiting seat 207, pressure is applied to the ball head body 204, thereby achieving the positioning of the protective shell 101 angle through friction. The structure is simple, and when the angle needs to be adjusted, it is only necessary to loosen the fastening bolt 208 to adjust the angle, which is convenient and quick.
[0032] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0033] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0035] Example 1, please refer to Figures 1-4A ball head angle adjustment mechanism for a projection lamp includes a protective component 1 and an angle adjustment structure 2 disposed at the bottom of the protective component 1. The protective component 1 includes a protective shell 101, and the angle adjustment structure 2 includes a support base 205. A spherical cavity 206 is disposed within the support base 205, and a ball head body 204 is connected within the spherical cavity 206. A connecting rod 203 is fixedly connected to the top of the ball head body 204, and a connector is disposed between the top end of the connecting rod 203 and the protective shell 101. A sliding groove is formed on the inner wall of the spherical cavity 206, and a limiting seat 207 is slidably connected within the sliding groove. An arc-shaped groove is provided on the side of the limiting seat 207 near the ball head body 204, and the arc-shaped groove is aligned with the ball head body 204. The outer surface contacts the ball head body 204. A fastening bolt 208 is connected to the side of the limiting seat 207 away from the ball head body 204 via a bearing. One end of the fastening bolt 208 extends to the outside of the support seat 205, and the fastening bolt 208 and the support seat 205 are threaded together. In this application, the ball head body 204 and the spherical cavity 206 cooperate with each other to form a ball hinge structure, which allows the protective shell 101 to swing freely in multiple directions. By tightening the fastening bolt 208 and the limiting seat 207, pressure is applied to the ball head body 204, thereby achieving the positioning of the protective shell 101 angle through friction. The structure is simple. When the angle needs to be adjusted, simply loosen the fastening bolt 208 to adjust the angle, which is convenient and quick.
[0036] Furthermore, such as Figures 1-4 As shown, the connector includes a connecting seat 202 fixedly installed at the top of the connecting rod 203. A threaded rod 201 is fixedly installed on the top of the connecting seat 202. A threaded groove 103 is provided at the bottom of the protective shell 101, and the inner wall of the threaded groove 103 is threadedly connected to the outer surface of the threaded rod 201. The angle adjustment structure 2 and the protective shell 101 can be detachably connected through the cooperation of the threaded rod 201 and the threaded groove 103.
[0037] Example 2 further optimizes the ball head angle adjustment mechanism of the projection lamp provided in Example 1. Specifically, the bottom of the support base 205 is provided with an installation component, which is used to install the mounting tube 209 onto the corresponding support object, such as a lamp pole.
[0038] Furthermore, such as Figure 3 and Figure 4 As shown, the mounting component includes a mounting tube 209 fixedly mounted at the bottom of the support base 205. Several mounting bolts 210 are threaded onto the mounting tube 209, and the ends of the mounting bolts 210 extend into the mounting tube 209. After the mounting tube 209 is fitted onto the support object, the mounting bolts 210 are tightened to complete the installation. In this embodiment, the orientation of the protective lens 102 is not restricted.
[0039] Example 3 further optimizes the ball head angle adjustment mechanism of the projection lamp provided in Example 1 or 2, specifically, as follows: Figure 3 As shown, a protective lens 102 is mounted on the front of the protective housing 101. The space between the protective lens 102 and the protective housing 101 is used to mount the lamp body. The protective lens 102 and the protective housing 101 are connected by bolts.
[0040] A protective element is provided between the back and front of the protective shell 101. The protective element is used to protect the lens 102 before use, reducing the possibility of the lens 102 being damaged by bumps during transportation.
[0041] Furthermore, such as Figures 1-4 As shown, the protective component includes two protective plates 3, which are respectively hinged to both sides of the protective shell 101 via damping hinges. When the two protective plates 3 are put together, they cooperate with the protective shell 101 to protect the protective lens 102.
[0042] Furthermore, each of the two protective plates 3 has a reflective film on one side. The reflective film is used to reflect light. When in use, the two protective plates 3 are unfolded, as shown... Figure 3 As shown, at this time, the protective plate 3 can reflect the scattered light toward the illuminated area through the reflective film on it.
[0043] Furthermore, such as Figure 2 As shown, a connecting rope 302 is fixedly installed on the side of the protective plate 3 away from the reflective film. A fixing seat 301 is sleeved on the outer surface of the connecting rope 302. The fixing seat 301 is installed on the back of the protective shell 101. The cooperation of the fixing seat 301, the connecting rope 302 and the damping hinge helps to maintain the stability of the protective plate 3 during use. The fixing seat 301 is located on the side of the protective shell 101.
[0044] Furthermore, such as Figure 2 As shown, a fixing bolt 303 is threaded onto the fixing base 301. One end of the fixing bolt 303 passes through the fixing base 301 and contacts the connecting rope 302. Tightening the fixing bolt 303 can fix the connecting rope 302. Loosening the fixing bolt 303 can pull the connecting rope 302. The connecting rope 302 is made of steel wire rope, which has high strength, high toughness and good wear resistance, and can withstand a large tensile force, so that the connecting rope 302 can pull the protective plate 3 when in use. In this embodiment, the protective lens 102 is used horizontally downward or tilted downward to improve the downward illumination of light.
