[0001] The utility model belongs to the technical field of lighting lamps, and in particular relates to a lamp holder capable of sliding and adjusting its position. Background Art

[0002] At present, common table lamps on the market usually include a lamp head, a support rod and a lamp base. The lamp head is installed on the lamp base through the support rod, and the position and angle between the lamp head and the lamp base are mostly fixed, resulting in the lamp head having the disadvantage of a single fixed lighting light projection angle.

[0003] In response to the above problems, China Utility Model Patent Application No. CN201720560549.5 discloses a high-freedom eye protection lamp, which includes a base, a connecting rod, and a lamp head connected in sequence. The lamp head includes a lampshade and a light source arranged in the lampshade. The lampshade has a slide groove, and the first end of the connecting rod is slidably connected to the slide groove; the lampshade of the eye protection lamp can slide back and forth relative to the connecting rod, so that the angle and position of the illumination light emitted by the light source can be linearly adjusted to meet the usage needs of different users in different positions and lighting angles in a limited space.

[0004] However, because the slideway of the aforementioned goggle lamp lacks a sliding, closed structure, the slot opening is permanently exposed, allowing dust, mosquitoes, and other foreign matter to easily fall into the lampshade through the slot, thereby contaminating the light source and other components within the lampshade. Therefore, it is necessary to improve the structure of existing desk lamps and provide a lamp head with a slidable position adjustment to address the above-mentioned problems in the prior art. Utility Model Content

[0005] The purpose of the utility model is to address the deficiencies in the prior art and to provide a lamp holder which has a reasonable design, is easy to use, has a sliding closed structure, and has a good protective effect and can be slidably adjusted.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A lamp head with a slidable position adjustment includes a lampshade, a light source assembly is provided inside the lampshade, a slide groove is opened at the top of the lampshade, a sliding closed structure is provided inside the slide groove, and the sliding closed structure includes a fixing frame, the fixing frame is fixedly installed on the inner side of the top of the lampshade, the top of the fixing frame is slidably connected to a closing plate for closing the slide groove, a hollow connecting column is passed through the middle of the closing plate, the upper end of the connecting column extends out of the slide groove, and the lower end of the connecting column is connected to a rotatable damping gear, and the damping gear is meshed with a damping rack provided on the fixing frame.

[0018] The utility model adopts the above technical solution and has the following technical effects:

[0019] The sliding closing structure provided by the utility model can be fixed to the inner side of the top end of the lampshade by means of screws and other fasteners through the fixing frame, so that the closing plate can be supported by sliding left and right on the top of the two track plates of the fixing frame; moreover, by passing the connecting column through the middle of the closing plate, it is possible not only to connect the lamp head to the lamp pole of the table lamp by means of the upper end of the connecting column extending out of the slide groove, but also to manually adjust the position of the connecting column in the slide groove so as to change the relative position of the connection between the lamp head and the lamp pole, thereby achieving the purpose of changing the lighting position and lighting range; compared with the prior art, the connecting column of the utility model can also drive the additional closing plate to move left and right during the movement of the slide groove, so as to use the closing plate to always close the notch of the slide groove, thereby solving the defect in the prior art that foreign matter such as dust, mosquitoes and the like can easily fall into the interior of the lampshade from the notch of the slide groove, and the protection effect is good.

[0020] In addition, the utility model has a rotatable damping gear connected to the lower end of the connecting column, and the damping gear is meshed with the damping rack provided on the fixed frame. Therefore, in the process of adjusting the relative position of the lamp head and the lamp pole through the connecting column, the movement of the lamp head can be neither too slow nor too fast due to the meshing connection of the damping gear and the damping rack. This can avoid the situation where the lamp head needs to be adjusted to an inclined state for lighting and one end moves downward and cannot be positioned due to too small friction resistance and too fast movement of the connecting column. It can also avoid the situation where the connecting column needs to be pushed hard and damaged due to too large friction resistance and too slow movement of the connecting column.
