4results about How to "Correct sitting posture" patented technology

The utility model discloses a study desk associated with myopia prevention and control relates to study desk technical field, including study desk main part and baffle plate, study desk main part upper end face is equipped with baffle plate, baffle plate inner wall is equipped with hydraulic rod, hydraulic rod tail end is equipped with support seat, the front end of support seat is equipped with connecting plate, and the connecting plate is equipped with the baffle plate. According to the learning table, the threaded rod is driven by the micro motor, the sliding block slides relative to the learning table body in the sliding groove through the threaded rod and is used for pushing the fixing support, the supporting plate is arranged on the outer surface of the supporting plate, and the supporting plate is arranged on the outer surface of the supporting plate. The distance control device is used for controlling the distance between a user and the learning table when the user uses the learning table, so that the sitting posture of the user is more correct, the pressure and discomfort of the spine are reduced, the proper distance is conveniently controlled, the phenomenon of myopia caused by too close watching and long-time watching is avoided, and the vision of the user is better protected.

The utility model discloses a multifunctional learning chair and relates to the technical field of learning equipment. Comprising a chair seat, a base plate is fixedly mounted on the upper end face of the chair seat, a sponge cushion is fixedly mounted on the upper end face of the base plate, a backrest is fixedly mounted on the side wall of the base plate, a sitting posture corrector is fixedly mounted on the upper end face of the sponge cushion, and fixing blocks are symmetrically and fixedly mounted on the outer wall of the base plate; a first supporting rod is fixedly installed on the upper end face of the fixing block, a handrail is fixedly installed on the upper end face of the first supporting rod, and a second sensor is fixedly installed on the outer wall of the sitting posture corrector. Through the arrangement of the sitting posture corrector, the second sensor, the fixing support and the first sensor, in the using process, the sitting posture of a user can be corrected, through the arrangement of the fixing support, the eyes of the user can be prevented from being too close to a table top, and therefore myopia is prevented, and through the arrangement of the first sensor and the second sensor, the myopia is prevented. And a warning effect can be achieved for a user.

The utility model provides a kind of double-screen backlight module and display device, double-screen backlight module includes display back frame, it includes bottom plate, first side edge being set along longitudinal direction, and second side edge being set along transverse direction, bottom plate, first side edge and second side edge are formed around and form accommodating cavity;Light guide piece is set in accommodating cavity;First optical film component and second optical film component are located on light guide piece, and in transverse direction closely connect;First, second optical film component is equipped with first privacy film and second privacy film respectively, and respectively has first louver microstructure layer and second louver microstructure layer;With transverse direction as light transmission axis direction, the deflection angle of two louver microstructure layers is α and β respectively relative to light transmission axis direction in turn, and there is relational expression: β-α=90 °±10 °. Double-screen backlight module is by limiting the observation angle of first optical film component, inhibits the light interference of second optical film component, while reducing overall thickness and frame width.

The utility model relates to the field of human life necessities, and provides a chair back structure and a chair, the chair back structure comprises a backrest and a pillow piece, the backrest is provided with a sliding seat which is vertically arranged along the height direction of the backrest; the pillow piece is located on the backrest side of the backrest and protrudes out of the surface of the backrest, the pillow piece is in sliding connection with the sliding base so that the pillow piece can serve as a headrest when moving to the upper side area of the backrest and serve as a back pillow when moving to the lower side area of the backrest, the purposes are diversified, good functionality is achieved, and when the pillow piece serves as the back pillow, the sitting posture correcting effect can be achieved; when the upper part of the human body is upright, the pillow piece can fill the gap between the back of the human body and the backrest, eliminate the suspension feeling generated by the back and well support the back of the human body, so that a user can keep a correct sitting posture, and meanwhile, the height position of the pillow piece can be adjusted according to the adaptability of users with different body types; therefore, a good supporting effect on the head or the back of a human body is ensured, and good practicability is achieved.
