Description

Technical Field

[0001] The invention relates to the technical field of foot pad lifting, in particular to a structure for regulating the lifting of a notebook computer. Background Art

[0002] Laptop lift mechanisms are mechanical devices that allow certain laptop components (such as the keyboard or screen) to move up and down to accommodate different usage needs or provide a better user experience. These are supported and adjusted by laptop feet, a common functional design component found on the bottom of laptops. The rubber footrests increase friction with the desktop surface, preventing the laptop from sliding or falling. They are particularly effective on smooth surfaces, alleviating the impact of desktop vibrations on delicate components like the laptop hard drive, reducing the risk of physical damage.

[0003] The laptop foot pads currently used are used to lift the laptop as a whole. When the user needs to adjust the direction of the keyboard, the laptop foot pad needs to be disassembled and its installation angle needs to be adjusted to achieve the purpose of adjusting the angle of the laptop keyboard. The adjustment process is relatively troublesome. In order to facilitate users to adjust the keyboard height, a foot pad structure that can be adjusted to rise and fall is specially developed.

[0010] Furthermore, the inner wall of the semicircular spring piece contacts the surface of the cross-slot rod, and the number of the resistance grooves is set to be several, and the several resistance grooves are arranged with the cross-slot rod as the center circumference. The surface of the triangular plate contacts the inner wall of the resistance groove, and the surface of the cross rod contacts the inner wall of the cross-slot rod.

[0011] Furthermore, the clamping component includes a telescopic rod, the top of the telescopic rod is fixedly connected to the top of the inner wall of the right-angle plate, the bottom of the telescopic rod is fixedly connected to the clamping plate, the bottom of the clamping plate is fixedly connected to the vertical plate, the surface of the vertical plate is slidably connected to the auxiliary plate, the top of the auxiliary plate is rotatably connected to the threaded rod, and the ends of the auxiliary plate and the clamping plate that are close to each other are respectively fixedly connected to anti-slip pads.

[0017] The present invention has the following beneficial effects:

[0018] The present invention places the notebook on top of the fixed plate, and the bottom of the notebook contacts the protective pad. The protective pad is used to increase the friction between the fixed plate and the notebook to prevent the notebook from slipping during use. When the angle of the notebook keyboard needs to be adjusted, the resistance component is pushed to separate. At this time, the fixed plate is pushed to rotate downward, and the angle of the notebook keyboard is adjusted by the inclination angle of the fixed plate. When the fixed plate rotates, the driving wheel is driven to rotate by the rotating rod. When the driving wheel rotates, the engaging frame is driven to rotate by engagement. The bottom of the foot pad contacts the top of the desktop when installed. When the engaging frame rotates, it moves upward by engaging with the tooth plate, thereby adjusting the height of the fixed plate by the engagement of the engaging frame and the tooth plate, so that the user can operate the notebook keyboard more comfortably.

[0019] When the height of the fixing plate needs to be adjusted, the present invention pushes the cross rod to slide on the surface of the rectangular rod and separates from the inner wall of the cross groove rod. At this time, the fixing plate can be pushed to adjust the angle. A triangular plate is provided inside the semicircular spring piece to contact the inner wall of the resistance groove. When the rotating rod rotates, it drives the cross groove rod to rotate and squeezes the triangular plate through the resistance groove, thereby increasing the resistance of the fixing plate during rotation, preventing the fixing plate from rotating rapidly due to the gravity of the notebook, causing the notebook to fall. After the angle adjustment of the fixing plate is completed, the cross rod is inserted into the inside of the cross groove rod to fix it, thereby preventing the fixing plate from protruding and rotating when the user operates the notebook, thereby improving the stability of the fixing plate in supporting the notebook.

[0020] When the present invention needs to fix the rotating frame, the threaded rod is twisted to rotate, and the threaded rod pushes the auxiliary plate downward through the threaded connection with the clamping plate. After the bottom of the clamping plate is placed on the top of the table, the threaded rod is twisted to start reversing. At this time, the threaded rod pushes the auxiliary plate to move upward and contact the bottom of the table, thereby completing the installation of the rotating frame. The rotating frame can be fixed to the table by twisting the threaded rod, which improves its convenience during installation. The clamping plate is connected to the right-angle plate through a telescopic rod. When the height of the rotating frame is adjusted, the telescopic rod is pulled to extend. The telescopic rod is used to limit the rotating frame, thereby improving the stability of the rotating frame during operation.

[0021] When the fixed plate of the present invention rotates, it squeezes the extrusion plate through the sliding hole plate, so that the extrusion plate can push the sliding frame to slide on the surface of the sliding hole plate. When the sliding frame moves, it pushes the elastic rod to move toward the outer end of the sliding hole plate. When the elastic rod moves, it pushes the pressure plate to squeeze the triangular contact frame, so that the pressure plate can push the triangular contact frame to move upward. When the triangular contact frame moves upward, it pushes the blocking pad to move upward through the connection between the moving rod and the reinforcement frame, so that the blocking pad can move to the top outer end of the fixed plate. At this time, the blocking pad will contact the end of the notebook, and the blocking pad will be used to limit the notebook to prevent the notebook keyboard from slipping due to tilting after the angle adjustment is completed.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
