DETAILED DESCRIPTION

[0016] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings.

[0017] Embodiment 1: A lamp cup with adjustable lighting range, referring to Figure 1 and Figure 2 , including a lamp body 1, a first bulb 11 is installed at the bottom of the lamp body 1, a symmetrically distributed guide rod 4 is fixedly connected to the middle of the lamp body 1, a first sliding sleeve 2 and a second sliding sleeve 3 are slidably connected between the symmetrically distributed guide rods 4 from bottom to top, the first sliding sleeve 2 is sleeved on the lamp body 1, the second sliding sleeve 3 is sleeved on the first sliding sleeve 2, a second bulb 21 is installed at the bottom of the first sliding sleeve 2, a third bulb 31 is installed at the bottom of the second sliding sleeve 3, a telescopic component is arranged on the guide rod 4, the telescopic component is used for telescoping the second bulb 21 and the third bulb 31, a connecting shell 6 is fixedly connected to the bottom of the sleeve 51, a heat dissipation hole is opened on the connecting shell 6, and a focusing sleeve 7 is fixedly connected to the bottom of the connecting shell 6.

[0018] The telescopic assembly includes a sleeve 51, which is slidably connected between the symmetrically distributed guide rods 4, and the sleeve 51 is sleeved on the lamp body 1. The bottom of the sleeve 51 is fixedly connected to the top of the second sliding sleeve 3. The outer circle of the sleeve 51 is threaded, and a threaded sleeve 52 is threaded on the outer circle of the sleeve 51. The threaded sleeve 52 is rotatably connected to the lamp body 1. Two first springs 5 ​​are fixedly connected between the first sliding sleeve 2 and the second sliding sleeve 3, and the two first springs 5 ​​are sleeved on the guide rod 4.

[0019] When in use, the first bulb 11, the second bulb 21 and the third bulb 31 are used for lighting. Since the second bulb 21 and the third bulb 31 are retracted in the focusing sleeve 7, the lighting range of the lamp cup is relatively concentrated. When the lighting range needs to be adjusted, the threaded sleeve 52 is rotated, and the threaded sleeve 52 is threadedly matched with the sleeve 51 to move the sleeve 51 downward, thereby driving the second sliding sleeve 3 and the third bulb 31 to move downward. The second sliding sleeve 3 drives the first sliding sleeve 2 and the second bulb 21 to move downward through the first spring 5. When the first sliding sleeve 2 moves downward to the limit, the second bulb 21 and the first bulb 11 are at the same level. On the plane, that is, the second bulb 21 extends out of the focusing sleeve 7. At this time, the lighting range of the first stage is expanded. When the lighting range needs to be further expanded, the threaded sleeve 52 continues to be rotated. Since the first sliding sleeve 2 moves to the limit and no longer moves downward, the sleeve 51 drives the second sliding sleeve 3 and the third bulb 31 to continue to move downward, so that the first spring 5 is compressed, so that the third bulb 31 is on the same horizontal plane as the second bulb 21 and the first bulb 11, that is, the third bulb 31 extends out of the focusing sleeve 7. At this time, the lighting range of the second stage is expanded. In this way, the lighting range can be flexibly adjusted according to actual conditions, which is convenient for customers to use.

[0020] Example 2: Based on Example 1, refer to Figure 1 and Figure 3 , and also includes a connecting block 8, which is fixedly connected to the top of the lamp body 1, and a sphere 81 is fixedly connected to the top of the connecting block 8. A connecting column 82 is movably connected to the sphere 81, and a positioning component is provided on the connecting column 82, which is used to position the sphere 81.

[0021] The locking assembly includes a locking ball 83, which is slidably connected in the connecting column 82. A second spring 84 is fixed between the locking ball 83 and the connecting column 82. The upper part of the sphere 81 is provided with locking holes distributed at equal intervals, and the locking ball 83 is locked into the locking holes.

[0022] Through the movable connection between the connecting column 82 and the spherical body 81 , the lamp cup can adjust the lighting angle, and the angle of the lamp cup can be fixed by the cooperation between the clamping hole on the spherical body 81 and the clamping ball 83 .

[0023] The above is a detailed introduction to the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
