Description

Technical Field

[0001] This utility model relates to the field of study desk technology, specifically a study desk with legs that can be raised and lowered synchronously. Background Technology

[0002] A study desk is a learning aid designed specifically for children and teenagers. It combines the principles of ergonomics, biomechanics, and human physiology to provide a healthy and comfortable learning environment. Study desks are classified by material into solid wood, composite materials, and plastic materials. Solid wood study desks are more environmentally friendly and durable, while composite material study desks are more economical and also have certain environmental performance and durability. Study desks with adjustable height legs are a very common type of study desk.

[0003] During the use of a study desk, it is first moved to the designated location using the base. Then, people sit in front of the desk and place books on the top of the desktop. The desktop then holds the books in place, thus assisting people in their studies. However, during the use of a study desk, the height adjustment handle and desktop tilt handle are usually installed on the side of the desk. When the study desk is located in a narrow area such as a corner, it is difficult for people to operate the height adjustment handle and desktop tilt handle. In addition, most study desks are supported by a single leg. If the weight is unevenly placed in front and behind, the study desk is prone to tilting and falling over, thus affecting its use. Utility Model Content

[0004] The purpose of this invention is to provide a study table with legs that can be raised and lowered synchronously, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a study table with synchronously height-adjustable legs, comprising a base, height-adjustable legs, and a frame. The height-adjustable legs are connected to both sides of the top of the base, and the top of the height-adjustable legs is connected to the frame. A height-adjustable rocker arm is connected to one side of the outer wall of the frame, and the height-adjustable rocker arm is connected to a hexagonal rod connector via a rotating column. A protective column is fixedly connected to the side of the frame near the height-adjustable rocker arm, and an inclined rocker arm is connected to one side of the outer wall of the protective column. A rotating rod is connected to the outer wall of the inclined rocker arm. A height-adjustable rod is installed inside the height-adjustable legs.

[0006] Preferably, a right-angle actuator is connected to the side of the rotating rod away from the inclined remote rod, and a transmission column is connected inside the right-angle actuator.

[0007] Preferably, the transmission column is connected to a second right-angle transmission on the side away from the first right-angle transmission, and the second right-angle transmission has a threaded rod inside.

[0008] Preferably, a threaded seat is threadedly connected to the middle of the outer wall of the threaded rod, and a transmission rod is rotatably connected to both sides of the outer wall of the threaded seat.

[0009] Preferably, a lifting rod is rotatably connected to the side of the transmission rod away from the threaded seat, and an inclined support plate is connected to the top of the outer wall of the lifting rod.

[0010] Preferably, the top of the outer wall of the inclined tray is connected to a desktop plate, and the bottom of the outer wall of the desktop plate is connected to the frame.

[0011] Preferably, the bottom end of the lifting rod is rotatably connected to the frame, and the transmission rod, the lifting rod, and the inclined support plate form a movable support.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this study desk with synchronously height-adjustable legs, rotating the lifting lever causes the legs to rise and fall synchronously, thereby causing the frame to move the desktop to a specified height; and rotating the tilt lever changes the tilt angle of the desktop, thereby adjusting the height and angle of the desktop, so that the height and angle of the desktop correspond to people's height and usage habits, thus making the design of the study desk conform to ergonomic design, which can effectively distribute the pressure on the upper body and reduce the burden on the shoulders and neck. Therefore, when using the study desk with synchronously height-adjustable legs, it facilitates the adjustment of the desktop angle and height. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model provides a technical solution: a study desk with synchronously height-adjustable legs, including a base 1, height-adjustable legs 2, and a frame 3. The height-adjustable legs 2 are connected to both sides of the top of the base 1, and the top of the height-adjustable legs 2 is connected to the frame 3. A height-adjustable rocker arm 4 is connected to one side of the outer wall of the frame 3, and the height-adjustable rocker arm 4 is connected to a hexagonal rod connector 5 via a rotating column. A protective column 6 is fixedly connected to the side of the frame 3 near the height-adjustable rocker arm 4, and an inclined lever 7 is connected to one side of the outer wall of the protective column 6. A rotating rod 8 is connected to the outer wall of the inclined lever 7. A height-adjustable rod is installed inside the height-adjustable legs 2. A first right-angle transmission device 9 is connected to the side of the rotating rod 8 away from the inclined lever 7, and a transmission column 10 is connected inside the first right-angle transmission device 9. The transmission column 10 is located away from the first right-angle transmission device 9. One side of device 9 is connected to a second right-angle actuator 11, and the second right-angle actuator 11 is internally connected to a threaded rod 12; the middle of the outer wall of the threaded rod 12 is threadedly connected to a threaded seat 13, and the two sides of the outer wall of the threaded seat 13 are rotatably connected to a transmission rod 14; the side of the transmission rod 14 away from the threaded seat 13 is rotatably connected to a lifting rod 15, and the top of the outer wall of the lifting rod 15 is connected to an inclined support plate 16; the top of the outer wall of the inclined support plate 16 is connected to a tabletop plate 17, and the bottom of the outer wall of the tabletop plate 17 is connected to the frame 3; the bottom of the lifting rod 15 is rotatably connected to the frame 3, and the transmission rod 14, the lifting rod 15 and the inclined support plate 16 form a movable support; the frame 3 and the lifting rocker arm 4 can slide a short distance, and the protective column 6 and the inclined rocker arm 7 can slide a short distance.

[0021] In practice, when the height of the desktop 17 needs to be adjusted during the use of the study desk with synchronously height-adjustable legs, the transmission component at the top of the lifting rod inside the lifting leg 2 is connected through the hexagonal rod connector 5. First, the lifting rocker 4 is pulled to move linearly a certain distance, so that the lifting rocker 4 is disengaged from the frame 3. Then, the lifting rocker 4 is manually rotated, and through the cooperation of the hexagonal rod connector 5, the lifting rods inside the four sets of lifting legs 2 work simultaneously, so that the legs are raised and lowered synchronously until the frame 3 moves the desktop 17 to the specified height. The legs are set to have two on each side, thus providing stable support for the study desk.

[0022] Next, pull the tilt lever 7 a certain distance to disengage it from the protective post 6. Since the tilt lever 7 is connected to the rotating rod 8, manually rotating the tilt lever 7 will cause the rotating rod 8 to rotate as well. Because the rotating rod 8 is connected to the transmission post 10 via the first right-angle actuator 9, rotating the rotating rod 8 will cause the transmission post 10 to rotate as well via the first right-angle actuator 9. Furthermore, because the transmission post 10 is connected to the threaded rod 12 via the second right-angle actuator 11, rotating the transmission post 10 will cause the threaded rod 12 to rotate as well via the second right-angle actuator 11. Since the threaded rod 12 and the threaded seat 13 are connected by a thread, rotating the threaded rod 12 will cause the threaded seat to rotate as well. 13 moves linearly, and because the threaded seat 13 and the transmission rod 14 are rotatably connected, the movement of the threaded seat 13 will drive the transmission rod 14 to rotate. At this time, the included angle between the threaded seat 13 and the transmission rod 14 will change, thereby generating a thrust on the lifting rod 15, causing the lifting rod 15 to rotate. Because the top of the lifting rod 15 is connected to the inclined support plate 16, the movement of the lifting rod 15 will drive the inclined support plate 16 to rotate together. And because the inclined support plate 16 is connected to the tabletop plate 17, the movement of the inclined support plate 16 will generate a thrust on the tabletop plate 17, causing the bottom of the tabletop plate 17 to rotate along the frame 3, changing the tilt angle of the tabletop plate 17 until it rotates to the specified angle.

[0023] Then, the angle of the desktop 17 is adjusted so that its height and angle correspond to people's height and usage habits, thus making the design of the study desk conform to ergonomic design. This allows it to effectively distribute pressure on the upper body and reduce shoulder and neck strain. Furthermore, the lifting rocker 4 and tilting lever 7 are located on the front of the frame 3, so that the lifting rocker 4 and tilting lever 7 can be used normally when the study desk is in a narrow area. This facilitates the adjustment of the desktop angle and height when using a study desk with synchronized height adjustment of the legs.

[0024] In summary, when using this type of study desk with synchronously height-adjustable legs, the desk is first moved to a designated position via the base 1. Then, people sit in front of the frame 3 and place books on the top surface of the desktop 17. The desktop 17 then limits the books, thus assisting people in their studies. This is existing technology and will not be elaborated further here. By rotating the lifting lever 4, the desk legs are raised and lowered synchronously, which in turn causes the frame 3 to move the desktop 17 to a designated height. Furthermore, by rotating the tilt lever 7, the tilt angle of the desktop 17 is changed, thereby adjusting the height and angle of the desktop 17. This ensures that the height and angle of the desktop 17 correspond to the user's height and usage habits, making the study desk ergonomically designed to effectively distribute pressure on the upper body and reduce shoulder and neck strain. Content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
