Description

Technical Field

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

[0002] A desk lamp generally refers to an electric lamp with a base that is placed on a table. It is generally divided into two types: one is a column type, and the other is a clamp-on type.

[0003] A Chinese patent discloses a clamp-type desk lamp that is easy to adjust, with the publication number CN210069567U, comprising a desk lamp base, a variable resistor fixedly installed inside the desk lamp base, an upper clamp fixedly installed at the bottom of the desk lamp base, a fixing frame fixedly installed at the middle position of the bottom of the upper clamp, a torsion spring fixedly installed at the middle part of the fixing frame, a lower clamp fixedly installed at the lower end of the fixing frame, a protective pad fixedly installed on the lower side of the lower clamp, an upper gasket fixedly installed on the right side of the upper surface of the lower clamp, and a lower gasket fixedly installed on the right side of the lower surface of the upper clamp. The clamp-type desk lamp that is easy to adjust can reduce or increase the resistance of the variable resistor connected to the circuit by adjusting the knob, thereby changing the resistance of the entire circuit, and then changing the current flowing into the LED light group, and finally changing the brightness of the LED light group, so as to achieve the purpose of changing the lighting brightness of the desk lamp.

[0004] However, it still has the following disadvantages: the device uses the torsion force of the torsion spring to clamp the upper and lower clamps on the edge of the table, but the device can only clamp and install the edge of the table with a fixed thickness. When the table is thicker or thinner, the outer surfaces of the upper and lower clamps cannot be well clamped with the edge of the table, and the lower clamp of the device is tilted, so it cannot be placed on the table, making its application scenario small. To this end, we propose a desk lamp with a clamping structure to solve this problem. Utility Model Content
