Description

A desk lamp provided with a lampshade unfolding mechanism

technical field

The invention relates to the field of desk lamps, in particular to a desk lamp provided with a lampshade unfolding mechanism.

Background technique

Existing table lamp lampshades generally have a single shape and function, all of which only play the role of protecting the lamps, and wrapping the lamps for a long time leads to poor heat dissipation, which cannot satisfy people's use.

Therefore, existing desk lamp needs further improvement.

The object of the present invention is to provide a desk lamp provided with a lampshade unfolding mechanism in order to overcome the disadvantages of the prior art.

In order to achieve the above object, the present invention adopts the following scheme:

A table lamp equipped with a lampshade unfolding mechanism, including a lamp holder and a lamp, characterized in that a lampshade is arranged above the lamp, and the lampshade is composed of a first baffle and a second baffle evenly distributed around the circumference, and the lampshade An unfolding mechanism capable of unfolding the lampshade is arranged below, and a lifting mechanism capable of driving the unfolding mechanism to realize the unfolding action is arranged under the unfolding mechanism.

A table lamp with a lampshade unfolding mechanism as described above is characterized in that the lifting mechanism includes a motor inside the upper end of the lamp stand, and a screw is provided on the motor shaft of the motor, and the screw thread is matched with a moving The upper end of the screw rod is inserted into the fixed seat through a bearing, and a lamp holder is arranged above the fixed seat, and the lamp is arranged on the lamp holder.

A desk lamp equipped with a lampshade unfolding mechanism as described above is characterized in that the unfolding mechanism includes a first baffle that is evenly distributed around the circumference of the moving seat and connected to it, and the lower end of the first baffle is provided with a spring and a lamp. The upper ends of the frame are connected, the inner wall of the first shield is provided with a first connecting seat, the first connecting seat is plugged with a connecting rod, the other end of the connecting rod is plugged with a second connecting seat, the second The connecting seat is arranged on the outer wall surface of the second shield, and the lower end of the second shield is plugged into the fixing seat.

A desk lamp with a lampshade unfolding mechanism as described above is characterized in that a control switch is provided on the lower surface of the lamp holder.

In summary, the present invention has the beneficial effects relative to the prior art as follows:

The invention is simple in structure and easy to use. The motor drives the lifting mechanism to move up and down, so that the lampshade unfolding mechanism realizes the opening and closing action, so that the lampshade protects the lamp and at the same time improves the heat dissipation effect and lighting effect of the lamp through the unfolding of the lampshade, thereby satisfying people's needs. .

Detailed ways

The invention will be further described below in conjunction with the description of the accompanying drawings and specific embodiments:

As shown in Figures 1 to 5, a desk lamp with a lampshade unfolding mechanism includes a lamp holder 1 and a lamp 2, a lampshade 3 is arranged above the lamp 2, and the lampshade 3 is composed of a first shield 4 and a lamp 2. The second baffle 5 is evenly distributed around the circumference, and the underside of the lampshade 3 is provided with a deployment mechanism 6 that can expand the lampshade 3. The bottom of the deployment mechanism 6 is provided with a lifting mechanism 7 that can drive the deployment mechanism 6 to realize the deployment action. 11 drives the lifting mechanism 7 to move up and down, so that the lampshade 3 unfolding mechanism 6 realizes the opening and closing action, so that the lampshade 3 protects the lamp 2 and improves the heat dissipation effect and lighting effect of the lamp 2 through the expansion of the lampshade 3, thereby satisfying people.

The lifting mechanism 4 of the present invention includes a motor 11 inside the upper end of the lamp holder 1, a screw 12 is arranged on the motor shaft of the motor 11, and a moving seat 13 is threaded on the screw 12, and the upper end of the screw 12 passes through a bearing Inserted on the fixed seat 14, the above fixed seat 14 is provided with a lamp holder 15, and the lamp 2 is arranged on the lamp holder 15, and the motor 11 drives the screw rod 12 to rotate, thereby driving the movable seat 13 to move up and down.

The deployment mechanism 6 according to the present invention includes the moving seat 13 which is uniformly distributed on the circumference and connected with the first cover 4, the lower end of the first cover 4 is provided with a spring 20 connected to the upper end of the lamp holder 1, and the first cover 4 is connected to the upper end of the lamp holder 1. The inner wall of a baffle 4 is provided with a first connecting seat 21, the first connecting seat 21 is plugged with a connecting rod 22, the other end of the connecting rod 22 is plugged with a second connecting seat 23, and the second connecting seat 23 is arranged on the outer wall surface of the second baffle 5, the lower end of the second baffle 5 is plugged on the fixed seat 14, and the moving seat 13 moves up and down to connect with the first baffle 4 and the spring 20 of the lamp holder 1, thereby Drive the first baffle 4 to rotate, thus drive the second baffle 5 to rotate, so as to realize the unfolding and closing of the lampshade 3 .

The lower surface of the lamp holder 1 according to the present invention is provided with a control switch 31 for conveniently controlling the operation of the motor 11 .
