Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a schematic structural diagram of an embodiment of the desk lamp of the present application; FIG. 2 is a schematic view of an embodiment of a lamp post assembly of the present application in a first state; fig. 3 is a schematic structural diagram of an embodiment of a lamppost assembly in a second state according to the present application.

The present application provides a table lamp 100. The desk lamp 100 includes a desk lamp body 10. The desk lamp body 10 includes a lamp post assembly 1. The lamp post assembly 1 is located the lower part of the desk lamp body 10, and the lamp post assembly 1 plays a role in supporting and fixing. The lamppost assembly 1 comprises a base housing 11, a suction cup member 12 and a drive assembly 14. The base housing 11 is placed on the work surface 20. The base housing 11 serves to accommodate and accommodate the sucker 12. The work surface 20 may be a table top, a bench top, etc.

The chuck member 12 is disposed in the base housing 11. The end of the suction member 12 facing the working surface 20 is provided with a suction opening 1211. When the air pressure in the suction cup 1211 is less than the external ambient air pressure, the suction cup 1211 is attached to the working surface 20. When the air pressure in the suction cup 1211 is equal to the external ambient air pressure, the suction cup 1211 is released from the suction connection with the working surface 20.

The driving assembly 14 includes a rotating member 141 and a linkage assembly 142. At least one end of the rotating member 141 is located outside the base housing 11. Such as one end or both ends of the rotation member 141, protrudes out of the outer circumferential surface of the base housing 11. One end of the link assembly 142 is connected to the rotation member 141. The middle part of the linkage assembly 142 is hinged in the base housing 11. The other end of the linkage component is connected with the suction cup piece 12. By driving the rotation member 141 to rotate, the rotation member 141 rotates to drive one end of the linkage assembly 142 to fall or rise. Because the middle part of the linkage component 142 is hinged in the base shell 11, the linkage component 142 can rotate relative to the base shell 11, so that the other end of the linkage component 142 drives the sucker 12 to lift or fall. As the suction cup member 12 is raised, the suction cup ports 1211 are attracted to the work surface 20. When the suction member 12 is dropped, the suction port 1211 is released from the work surface 20.

If the rotating member 141 rotates to drive one end of the linking component 142 to fall, one end of the linking component 142 falls to drive the other end of the linking component 142 to rise, thereby driving the sucker 12 to rise. When the suction cup member 12 is lifted, the air pressure in the suction cup 1211 is smaller than the air pressure of the external environment, and the suction cup 1211 is tightly adhered to the working surface 20, so that the desk lamp body 10 is tightly fixed on the working surface 20.

If the rotating member 141 rotates to drive one end of the linking component 142 to lift, one end of the linking component 142 lifts to drive the other end of the linking component 142 to fall. When the sucking disc 12 falls, the sucking disc 12 sinks according to the difference between the internal air pressure and the external air pressure and the self rigidity, the air pressure in the sucking disc opening 1211 is the same as the air pressure in the external environment, the sucking disc opening 1211 is desorbed from the working surface 20, and the movability of the desk lamp body 10 is further realized. Therefore, the base shell 11, the suction cup piece 12, the rotating piece 141 and the linkage assembly 142 are matched with each other, so that the stability of fixing the desk lamp body 10 is improved, and the desk lamp body 10 cannot topple over due to vibration, collision and the like; meanwhile, the desk lamp body 10 is convenient to move.

The other end of the connecting bar 1421 is connected to the suction cup member 12. The rotating member 141 penetrates the locking block 1422 and drives the locking block 1422 to lower or raise the connecting rod 1421 near one end of the locking block 1422.

When the desk lamp body 10 needs to be fixed on the working surface 20, the driving handle 143 is pressed downwards, the rotating member 141 drives the locking block 1422, the locking block 1422 rotates to press down one end of the connecting rod 1421 close to the locking block 1422, the end of the connecting rod 1421 close to the sucker 12 is lifted, the sucker 12 is pulled up, at this time, the air pressure in the sucker 12 is smaller than the air pressure in the external environment, and the desk lamp body 10 is tightly fixed on the working surface 20.

When the fixed state of the desk lamp body 10 needs to be released, the driving handle 143 is lifted up, the locking block 1422 is driven by the rotating piece 141, the limiting of the connecting rod 1421 is released by the locking block 1422, one end, close to the locking block 1422, of the connecting rod 1421 is lifted up, the connecting rod 1421 is descended close to the sucker 12, the sucker 12 sinks according to the difference between the internal air pressure and the external air pressure and the rigidity of the sucker 12, the internal air pressure of the sucker 12 is consistent with the external environment air pressure, and the desk lamp body 10 can move.

The other end of the linkage component is connected with the sucker piece. The rotating piece rotates to drive one end of the linkage assembly to descend or ascend, so that the other end of the linkage assembly drives the sucker piece to ascend or descend. When the sucker piece is lifted, the sucker mouth is attracted to the working surface; when the sucking disc piece descends, the sucking disc opening and the working surface are removed from adsorption. The rotating piece and the linkage assembly are matched with each other, so that the stability of fixing the desk lamp body is improved, and the desk lamp body cannot topple due to vibration collision and the like; simultaneously also easily the desk lamp body removes.

The terms "first", "second" and "third" in the present application are used for descriptive purposes only and are not to be construed as indicating the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of the feature. In the embodiment of the present application, all directional indicators (such as up, down, left, right, front, rear \8230;) are used only to explain the relative positional relationship between the components, the motion situation, etc. at a specific posture (as shown in the drawing), and if the specific posture is changed, the directional indicator is changed accordingly. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. A process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to the listed steps or elements but may alternatively include additional steps or elements not listed or inherent to such process, method, article, or apparatus.

The above description is only an example of the present application and is not intended to limit the scope of the present application, and all modifications of equivalent structures and equivalent processes, which are made by the contents of the specification and the drawings, or which are directly or indirectly applied to other related technical fields, are intended to be included within the scope of the present application.
