The invention discloses an indoor 5G antenna. The antenna comprises an antenna work box, a connecting plate is arranged at the top of the antenna working box; an antenna body is arranged at the top ofthe connecting plate; an adjusting rotating shaft is fixedly mounted at the bottom of the connecting plate; a rotating bearing is mounted in the outer ring of the lower end of the adjusting rotatingshaft; the bottom of the rotating bearing is fixedly connected with the top of the antenna working box; a mounting base is fixedly mounted at the bottom of the antenna body; a rotating rod penetratesthrough and is fixedly mounted on the mounting base in the front-back direction; partition plates are fixedly mounted at the top of the connecting plate; the two partition plates are symmetrically arranged. The free end of the rotating rod penetrates through the partition plates and is rotationally installed on the partition plates. The antenna body is provided with a first clamping sleeve and a second clamping sleeve, a first clamping plate is fixedly installed on the front end face of the first clamping sleeve, and a second clamping plate is fixedly installed on the front end face of the second clamping sleeve. The orientation position of the antenna body is changed randomly, so that distribution of indoor 5G signals can be adjusted by adjusting the orientation and angle of the 5G antenna.

The invention discloses a multifunctional art creation table. The multifunctional art creation table mainly comprises a base, a middle frame, an outer frame, an end plate, a supporting frame, an axlejack and a swing arm, wherein a drawer shell is fixedly arranged on the upper part of the right side of the base, side plates are fixedly arranged on the front side wall and the rear side wall of thebase, an opening of the drawer shell is rightward, a drawer is arranged on the inner side of the drawer shell in a sliding and inserting mode, rollers which are arranged at equal intervals are rotationally arranged on the front inner wall and the rear inner wall of the drawer shell, and grooves matched with the rollers are formed in the front outer wall and the rear outer wall of the drawer. The multifunctional art creation table is reasonable in structural design, stable in angle adjustment and supporting and simple in structure, and the service life can be guaranteed; bottom fill-in light ofrubbing can be carried out, and the multifunctional art creation table is more convenient; a combined table top is adopted, tools are stably placed, the placement positions of unused painting brushesand the placement positions of used painting brushes are separated, and the practicability is good; and the width of the table top can be adjusted, the two ends can swing to the left side and the right side, the arrangement is arranged in a surrounding mode, so that articles on the end plate can be conveniently taken out and placed, and the table is more practical.

The invention relates to an electronic device with a multi-link hinge, which includes a fixed part and a rotating part. Several multi-link hinges are arranged between the fixed part and the rotating part. The feature is that the multi-link hinge is composed of several connecting rods. , the connecting rod includes a fixed connecting rod connected with the fixed part, a rotating connecting rod connected with the rotating part and an intermediate connecting rod group composed of at least two intermediate connecting rods, the fixed connecting rod is hinged with the moving connecting rod through the intermediate connecting rod group, The intersecting parts of two adjacent connecting rods are provided with a rotation axis, and the connecting rods are rotated around the rotation axis, and the two adjacent rotation axes in the same multi-link hinge are overlapped, and all the rotation axes in the same multi-link hinge extend infinitely and Intersect at one point to form rotation points, all rotation points remain stationary relative to the fixed part, and the rotation points are set on the sideline of the rotating part. The invention provides an electronic device with a multi-link hinge, which avoids affecting the internal space of the screen and can increase the rotation angle.
