Description

Technical Field

[0001] This utility model relates to the field of lamp housings, and more specifically, it relates to a lamp housing that facilitates the replacement of the light source. Background Technology

[0002] The lamp housing usually refers to the outer shell of a lamp, which is mainly used to protect the internal components and also serves as decoration, heat dissipation, or directional light.

[0003] A lamp housing typically consists of a lamp post and a lampshade. The light source is installed at the top of the lamp post, and the lampshade covers the light source, mainly serving to soften the light. When the light source is damaged during normal use, it needs to be replaced. Generally, the lampshade needs to be removed from the lamp post. After the lampshade is removed, people need to find a place to put it, especially when replacing the light source of a wall lamp. Because wall lamps are located at a relatively high position, it is difficult for people to find a place to put the lampshade, so they can only hold it by hand, which is inconvenient for replacing the light source.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a lamp housing that facilitates the replacement of the light source.

[0011] The present invention is further configured such that: a compression spring is provided in the sliding hole, and the end of the limiting member facing away from the compression spring is hemispherical.

[0012] In summary, this utility model has the following beneficial effects:

[0013] When it's time to replace the light source on the mounting bracket, the sliding block is driven downwards. This causes the outer cover to move downwards as well, gradually revealing the mounting bracket until it's fully exposed through the through-hole. Simultaneously, the distance between the top plate and the mounting bracket increases, providing more space for the light source and facilitating its installation. After installation, the sliding block is moved upwards until the top of the outer cover re-abuts the top plate. This design eliminates the need to remove the lampshade from the lamp post, eliminating concerns about its placement. Furthermore, the mounting bracket is fully exposed after the sliding block slides, making it easy to install the light source. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] A lamp housing that facilitates the replacement of light sources, such as Figure 1 and Figure 2As shown, the lamp includes a lamp post 1 and a lampshade. The top of the lampshade has a mounting base 2 for installing a light source. The light source is installed by screwing it into the mounting base 2. The lampshade includes a top plate 3 and an outer cover 4, which are separate from each other. A through hole is formed on the top surface of the outer cover 4. The diameter of the top plate 3 is larger than the diameter of the through hole, and the top plate 3 is coaxially aligned with the through hole, blocking the through hole. A sliding seat 5 is provided on the lamp post 1, allowing it to slide along the length of the lamp post 1. The outer cover 4 is fixedly connected to the sliding seat 5 by several connecting strips 6. When the sliding seat 5 moves the outer cover 4 downwards, the distance between the top plate 3 and the mounting base 2 increases, allowing for easier replacement of the mounting base 2. When installing the light source, people drive the sliding seat 5 downwards. At this time, the sliding seat 5 will drive the outer cover 4 downwards as well. The mounting seat 2 will slowly be exposed outside the outer cover 4 until the mounting seat 2 is fully exposed through the through hole. At the same time, the distance between the top plate 3 and the mounting seat 2 increases, so that there is more space between the top plate 3 and the mounting seat 2 to put the light source, which is convenient for the installation of the light source. After the light source is installed, people move the sliding seat 5 upwards until the upper end of the outer cover 4 is in contact with the top plate 3 again. Through the above settings, the lamp cover does not need to be removed from the lamp post 1, so there is no need to consider the placement of the lamp cover. After the sliding seat 5 slides, the mounting seat 2 can be fully exposed, which is convenient for people to install the light source.

[0021] like Figure 2 , Figure 3 and Figure 4 As shown, a sliding groove 7 is provided on the top surface of the lamp post 1, and a sliding strip 8 is slidably connected in the sliding groove 7. One end of the sliding strip 8 protruding from the top surface of the lamp post 1 is fixedly connected to the top plate 3. When the sliding seat 5 slides downward along the lamp post 1, the sliding seat 5 can drive the sliding strip 8 to slide upward. The sliding strip 8 is transparent. By sliding the sliding seat 5 downward, it can drive the sliding strip 8 to slide upward along the sliding groove 7, thereby causing the top plate 3 to move upward, while the position of the mounting base 2 on the lamp post 1 remains unchanged. This achieves the purpose of increasing the distance between the mounting base 2 and the top plate 3, thereby making it easier to install the light source on the mounting base 2. The outer peripheral wall of the lamp post 1 has... A rotating groove connected to the sliding groove 7 contains a gear 9 rotatably connected to it. The inner walls of the sliding strip 8 and the sliding seat 5 are all provided with meshing teeth. The two sides of the gear 9 mesh with the sliding strip 8 and the sliding seat 5 respectively. The sliding seat 5 and the lamp post 1 cannot move relative to each other. The outer peripheral wall of the sliding seat 5 is provided with several friction textures. When people hold the sliding seat 5, they drive the sliding seat 5 to move downward. During the downward movement of the sliding seat 5, the gear 9 will rotate, and the sliding strip 8 will mesh with the gear 9, so that the gear 9 drives the sliding strip 8 to slide upward. The friction textures increase the friction between the hand and the outer peripheral wall of the sliding seat 5.

[0022] like Figure 2 , Figure 3 and Figure 4As shown, a limiting component is provided on the lamp post 1 to restrict the sliding seat 5 from sliding on the lamp post 1. By providing the limiting component, when the top plate 3 abuts against the outer cover 4, the limiting component can restrict the sliding seat 5 from sliding on the lamp post 1, making it difficult for the sliding seat 5 to slide on the lamp post 1 without external force. A sliding hole 10 is provided on the outer peripheral wall of the lamp post 1, and the limiting component is slidably connected in the sliding hole 10. A limiting hole 11 is provided on the inner peripheral wall of the sliding seat 5. When the top surface of the sliding seat 5 is flush with the top of the lamp post 1, the limiting component is engaged in the limiting hole 11. By inserting the limiting component into the limiting hole 11, the limiting component achieves the limitation of the sliding seat 5. A compression spring 12 is provided in the 10. The end of the limiting member facing away from the compression spring 12 is hemispherical. The compression spring 12 always provides the limiting member with a sliding force facing away from the lamp post 1. During the downward sliding of the sliding seat 5, the limiting member is located in the sliding hole 10. When the limiting hole 11 moves to the position of the limiting member, the hemispherical end of the limiting member is embedded in the limiting hole 11 under the action of the compression spring 12. When people need to slide the sliding seat 5, they only need to apply a downward force to the sliding seat 5, so that the hemispherical end of the limiting member is subjected to the resistance force of the outer edge of the limiting hole 11 and moves towards the sliding hole 10, thereby releasing the limiting effect of the limiting member on the sliding seat 5.
