For achieving the above object, the utility model provides following technical scheme:
A kind of Folding desk lamp magnifier, comprise base, Collapsible rack, installing frame and the enlarging lens be located in installing frame, described base, Collapsible rack and installing frame are hinged successively, described installing frame is divided into magnifier district and surround towards the one side of base, described magnifier district offers installing port, described enlarging lens is embedded in installing port, some auxiliary lamp sheets are provided with around magnifier in described magnifier district, described surround is provided with some lighting lamp pieces, described base is provided with control knob and power supply, described auxiliary lamp sheet, lighting lamp piece, button and power electric connect, the corresponding installing port upset of one side of described installing frame base is dorsad provided with shielding cover.
One section of described installing frame base dorsad offers catching groove, is provided with to install to hook in described catching groove, the buckle portion that described shielding cover comprises cap and is fixedly connected with cap, described buckle portion with hook be installed connect.
Described installation hook comprises parallel-segment and overhead kick section, described parallel-segment one end is fixedly connected with catching groove sidewall, the other end is fixedly connected with overhead kick section, and the other end of opposing parallel section of overhead kick section is arranged towards catching groove diapire, and described buckle portion snapping is between parallel-segment and overhead kick section.
The end face of described base installing frame is dorsad provided with at least two foam-rubber cushions.
By adopting technique scheme, auxiliary lamp sheet is set separately by around magnifier, convenient clear when staff applies magnifier observation; Auxiliary lamp sheet and photo lamp sheet are set simultaneously, make the utility model in use can be used alone the functional lighting of desk lamp, also can use as illumination for magnifier arranges the lamp be used alone, moreover two groups of lamps are set also just have two kinds of illumination conditions, when the observation of use enlarging lens, two kinds of different bright degrees can be regulated to meet the observation requirements of varying environment by button; Installing frame correspond to installing port and arranges shielding cover, also shielding cover is just made can to cover a side of enlarging lens, the shielding cover under overturn cover when use function of desk lamp, need to rotate shielding cover when using enlarging lens observation station to expose magnifier and observe, and the setting of shielding cover can prevent dust etc. from withering and falling on enlarging lens by installing port, effectively ensure that the serviceable life of enlarging lens.
