Description

Writing board lamp capable of automatically lifting

Technical Field

The utility model relates to a clipboard lamp is a clipboard lamp that can rise automatically particularly.

Background

The target for the tablet light illumination needs to have a sufficient average illuminance on the one hand, a sufficiently high illuminance uniformity on the second hand, and again a prevention of teacher glare. However, in some classroom, a camera is installed on the front wall of the classroom for examination invigilation, and in this state, the writing board lamp close to one side of the camera can shield the camera under normal installation conditions, so that monitoring of the camera is affected. Aiming at the problem, on one hand, the lighting quality of the writing board surface under the normal learning condition is ensured, on the other hand, the normal operation of the camera in the invigilation process is required to be ensured, and the control of the writing board lamp is raised so as not to shield the camera.

Disclosure of Invention

The utility model aims at solving the above problem, provide a but clipboard lamp of automatic rising, can rise automatically, satisfy the functional requirement under the specific condition.

According to the technical scheme of the utility model, the writing board lamp capable of automatically lifting comprises a lifting component and a lamp, wherein the lifting component comprises a motor, a driving gear, a transmission gear, a screw rod, a rod sleeve and an extension push rod; the driving gear is arranged on a rotating shaft of the motor, the transmission gear is meshed with the driving gear, and the motor, the driving gear and the transmission gear are externally provided with a decorative box; the upper end of the screw rod extends into the rotating shaft of the decorative box connected with the transmission gear, the rod sleeve is sleeved outside the screw rod, and the upper end of the rod sleeve is connected with the decorative box; the extension push rod is installed on a screw of the screw rod, and the lower end of the extension push rod is connected with the lamp.

Furthermore, a connecting hole is formed in a rotating shaft of the transmission gear, and the upper end of the screw rod is inserted into the connecting hole and locked by a locking piece.

Furthermore, a cross beam is arranged on the lamp, and the lower end of the extension push rod is connected with the cross beam.

The beneficial effects of the utility model reside in that: simple structure, stability are high, and the appearance is pleasing to the eye, has realized the lift of lamps and lanterns, has satisfied the functional requirement under the specific condition.

Detailed Description

The invention will be further described with reference to the following specific embodiments and the accompanying drawings.

As shown in the figure: the writing board lamp capable of automatically lifting comprises a lifting assembly and a lamp 10. The lifting assembly comprises a motor 1, a driving gear 2, a transmission gear 3, a screw rod 6, a rod sleeve 8 and an extension push rod 9. Wherein, driving gear 2 installs in motor 1's pivot, and drive gear 3 meshes with driving gear 2 mutually, is equipped with outside motor 1, driving gear 2 and drive gear 3 and decorates box 11, and drive gear 3 utilizes bearing 4 to install on decorating the mount pad (not drawn in the picture) in the box 11, decorates the box and plays the guard action, has guaranteed simultaneously that the lifting unit appearance is clean and tidy. The screw rod 6 can move in a trapezoidal mode, the upper end of the screw rod 6 extends into the decoration box 11 to be connected with a rotating shaft of the transmission gear 3, the rod sleeve 8 is sleeved outside the screw rod 6 and radially restrained with the screw 7 to keep axial movement of the rod sleeve, and the upper end of the rod sleeve 8 is connected with the decoration box 11. The extension push rod 9 is arranged on the screw nut 7 of the screw rod 6, and the lower end of the extension push rod 9 is connected with the lamp 10.

Specifically, the rotating shaft of the transmission gear 3 is provided with a connecting hole, the upper end of the screw rod 6 is inserted into the connecting hole and locked by the locking part 5, the locking part 5 can be a bolt, and the connection stability is high. The lamp 10 is provided with a beam 12, the lower end of the extension push rod 9 is connected with the beam 12, and the length of the beam 12 is kept above 60mm in order to ensure the left and right gravity balance.

The working principle is as follows: the motor rotates, drives the lead screw through the gear, again because of the screw keep with rod cover axial degree of freedom, so the screw with axial motion, extend and keep the fastening connection between push rod and the screw, and then realize holistic axial motion, finally satisfy the demand that the clipboard lamp reciprocated.
