Description

Technical Field

[0001] The utility model relates to the technical field of table lamps, in particular to a detachable table lamp. Background Art

[0002] With the improvement of living standards, in order to meet the diverse needs of consumers, manufacturers have continuously improved and upgraded the appearance and structure of desk lamps, making them increasingly convenient and reliable.

[0003] To facilitate assembly and disassembly, existing desk lamps include detachable desk lamps. These typically include a lamp post and a lamp base. An elastic block and a snap-in groove are interlocked between the lamp post and the lamp base. When the elastic block is inserted into the snap-in groove, the elastic block undergoes elastic deformation due to the reaction force exerted by the snap-in groove, causing the elastic block and the snap-in groove to abut against each other and become fixedly connected, thereby connecting the lamp post and the lamp base. Furthermore, a mating male and female plugs are provided between the contact surfaces of the lamp post and the lamp base. When the elastic block abuts against the snap-in groove, the male and female plugs nest and mate, connecting the lamp's circuit and achieving illumination.

[0004] However, when pulling out the elastic block relative to the locking groove, the user needs to apply a large force to successfully pull out the elastic block. It is difficult to pull out the elastic block. In serious cases, the elastic block is likely to be broken. Obviously, the disassembly between the lamp pole and the lamp holder is extremely inconvenient and has poor practicality. Utility Model Content
