Abstract

An electric elevating easel for painting comprises a pedestal, an upper supporting frame for fixing the upper end of canvas, and a lower supporting frame for fixing the lower end of the canvas. In the use process, the up-and-down movement of the easel can be operated only through controlling a foot-operated switch by a foot, so the easel is convenient and fast to operate; and the tightness degree of the canvas can be finely tuned by finely tuning a clamping bolt, and a gear is clamped in a rack after height adjustment due to adoption of gear and rack cooperation to prevent free movement of the easel, so a device for restricting the free sliding of the upper supporting frame and the lower supporting frame is omitted, thereby the whole easel is simplified.

Description

An electric lifting easel for painting

technical field

The invention relates to an easel device, in particular to an electric lifting easel for painting.

Background technique

With the continuous increase of painting art lovers, the painting easel market continues to expand. In the process of using ordinary painting easels, it is not difficult to find that the up and down adjustment and lifting problems during use cause inconvenience in use and affect the performance of artists.

Contents of the invention

The purpose of the present invention is to provide an electric lifting easel for painting to solve the problem of inconvenient adjustment of the height of the existing easel

The present invention is for solving the deficiencies of the above-mentioned technical problems, and the technical scheme adopted is:

An electric elevating easel for painting, comprising a base, an upper support frame for fixing the upper end of the canvas, and a lower support frame for fixing the lower end of the canvas, two positioning rods are arranged on the base, and a surface setting rod is arranged between the positioning rods There is a rack column, two positioning rods pass through the two ends of the upper support frame and the lower support frame respectively, so that the upper support frame and the lower support frame slide along the length direction of the positioning rod, and the upper support frame and the lower support frame are respectively provided with The upper motor and the lower motor, the output shafts of the upper motor and the lower motor are respectively connected with the upper gear and the lower gear, and the upper gear and the lower gear cooperate with the rack on the column to form a rack and pinion mechanism. Rotate the drive gear to move on the rack so as to control the up and down movement of the upper support frame and the lower support frame.

The base is also provided with a power cord, one end of the power cord is respectively connected to the upper motor and the lower motor, and the other end is connected to the plug.

The base is also provided with an upper bracket foot switch and a lower bracket foot switch, and the upper bracket foot switch and the lower bracket foot switch respectively control the upper motor and the lower motor.

The upper support frame and the lower support frame are respectively provided with an upper fine-tuning clamping bolt and a lower fine-tuning clamping bolt.

The beneficial effects of the present invention are: the present invention only needs to use the foot to control the foot switch to operate the easel to move up and down, and the operation is convenient and fast. The combination of rack and pinion is used. After adjusting the height, the gear is stuck in the rack, which can also prevent the easel from moving freely, thus eliminating the need to set up a device that restricts the free sliding of the upper support frame and the lower support frame, making the entire device get simplified.

detailed description

As shown in the figure, the specific implementation method is as follows:

An electric lifting easel for painting, comprising a base 10, an upper support frame 7 for fixing the upper end of the canvas and a lower support frame 9 for fixing the lower end of the canvas, two positioning rods 5 are arranged on the base 10, and two positioning rods are arranged On the one hand, the rod 5 defines the sliding direction of the upper support frame 7 and the lower support frame 9. On the other hand, it also avoids its left and right shaking, so as to avoid affecting the painting due to the shaking. A column with a rack on the surface is arranged between the positioning rods 5 3. Two positioning rods 5 pass through the two ends of the upper support frame 7 and the lower support frame 9 respectively, so that the upper support frame 7 and the lower support frame 9 slide along the length direction of the positioning rod 5, and the upper support frame 7 and the lower support frame 9 An upper motor 4 and a lower motor 2 are respectively arranged on the top, and an upper gear and a lower gear are respectively connected to the output shafts of the upper motor 4 and the lower motor 2, and both the upper gear and the lower gear cooperate with the rack on the column 3 to form a rack and pinion Mechanism, through the rotation of the upper motor 4 and the lower motor 2, the driving gear moves on the rack so as to control the up and down movement of the upper support frame and the lower support frame. Since what the present invention uses is an easel, because the quality of the canvas is small, the gear The force between the racks can be used to support and prevent the free slide of the upper and lower support frames, so the device for limiting its slide can be omitted, so that the whole easel is simplified.

Described base 10 is also provided with power cord 1, and one end of power cord 1 is connected with upper motor 4 and lower motor 2 respectively, and the other end is connected with plug, and whole device is powered by being connected with power supply through plug.

The base 10 is also provided with an upper bracket foot switch 11 and a lower bracket foot switch 12, the upper bracket foot switch 11 and the lower bracket foot switch 12 respectively control the upper motor 4 and the lower motor 2, by controlling the upper motor 4 can control the whole canvas to move up, and can control the whole canvas to move down by controlling the lower motor 2, because after the canvas is fixed, the canvas is equivalent to a connecting piece so that the upper support frame 7 and the lower support frame 9 are connected together and can move synchronously.

The upper support frame 7 and the lower support frame 9 are respectively provided with an upper fine-tuning clamping bolt 6 and a lower fine-tuning clamping bolt 8 to avoid loosening of the canvas during the moving process.

The technical solutions and implementation methods listed in the present invention are not limiting, and solutions that are equivalent to or have the same effect as the technical solutions and implementation methods listed in the present invention are within the protection scope of the present invention.
