DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , which includes table legs 1 and a tabletop 2 assembled to the top of the table legs 1 by bolts, a folding frame 3. The folding frame 3 is composed of a fixed frame 31, folding plates 32, L-shaped plates 33 and transmission rods 34. Among them, the fixed frame 31 is rectangular, and the bottom of the fixed frame 31 is fixed to the upper surface of the tabletop 2 by screws. An X-shaped support member is welded inside the fixed frame 31 to enhance the support strength of the fixed frame 31. The folding plates 32 are arranged above the fixed frame 31, and the bottom of one group of folding plates 32 is fixed to the top of the fixed frame 31. After multiple groups of folding plates 32 are arranged in parallel, the total length is equal to the width of the tabletop 2. The height of the fixed frame 31 limits the distance between the folding plates 32 and the tabletop 2. When the folding frame 3 is parallel above the tabletop 2, things of a certain height can still be placed on the surface of the tabletop 2, avoiding the need to move the items placed on the surface of the tabletop 2 back and forth. The L-shaped plates 33 are fixed to both sides of the folding plates 32 by bolts. Fixed shafts are fixed at the two end corners of the side of the L-shaped plates 33 away from the folding plates 32. The transmission rods 34 are movably installed on the fixed shafts of the L-shaped plates 33 through mounting holes opened on the surface. The lengths of the upper and lower two transmission rods 34 are equal. The transmission rods 34 connect multiple groups of folding plates 32 through the L-shaped plates 33. When the placement area on the surface of the tabletop 2 is not enough, the folding frame 3 can be made parallel above the tabletop 2, so that the entire lifting table has an extra placement space. And when it is necessary to use the tabletop 2 for work or study, or when it is necessary to take the items on the surface of the tabletop 2, the tabletop 2 can be lifted upward from the side away from the fixed frame 31, so that the transmission rods 34 rotate and stand up, forming a storage rack mode, standing on one side above the tabletop 2, leaving most of the space above the tabletop 2 empty, facilitating users to study and work. And after the folding frame 3 stands up, the height between the folding plates 32 is the width dimension of the folding plates 32. When the height of the items placed above the folding plates 32 does not exceed the width dimension of the folding plates 32, there is no need to move the items above the folding plates 32 additionally, simplifying the operation when using the folding frame 3.

[0021] The surface of the table board 2 is provided with an installation groove 4. An angle adjustment device 5 is movably installed inside the installation groove 4. The angle adjustment device 5 includes a movable plate 51, a telescopic rod 52, a connecting plate 53, a support plate 54, a movable groove 55, a limiting rod 56 and a limiting groove 57. Among them, the movable plate 51 is located inside the installation groove 4, and the telescopic rod 52 is fixed at the center of the bottom of the movable plate 51. An installation hole is opened in the installation groove 4 corresponding to the position of the telescopic rod 52, and the bottom of the telescopic rod 52 is stuck inside the installation hole. The connecting plate 53 is fixed on the side of the movable plate 51 away from the fixed frame 31. Rotating shafts are fixed on both sides of the connecting plate 53. Grooves are opened in the support plate 54 corresponding to the position of the connecting plate 53. Movable rings are fixed on the inner wall of the groove corresponding to the rotating shafts of the connecting plate 53. By sleeving the movable rings with the rotating shafts, the connecting plate 53 is movably connected to the support plate 54. A rectangular movable groove 55 is opened on the surface of the support plate 54. A limiting rod 56 is movably installed at one side of the movable groove 55 away from the groove through a connecting shaft. A magnetic attraction stone is adhered to the end of the limiting rod 56 away from the connecting shaft. An iron sheet is arranged at the position of the inner wall of the movable groove 55 corresponding to the magnetic attraction stone to limit the movement of the limiting rod 56 through magnetism. A plurality of limiting grooves 57 are opened on the side of the surface of the movable plate 51 away from the connecting plate 53. When the limiting rod 56 is stuck inside different limiting grooves 57, the support plate 54 and the table board 2 can form different angles. When adjusting the angle of the support plate 54, press the side of the support plate 54 close to the connecting plate 53 to make the other side of the support plate 54 tilt up. Then pull the movable plate 51 upward to stretch the telescopic rod 52, so that the bottom of the support plate 54 is located above the table board 2. Push the limiting rod 56 towards the movable plate 51 to make the bottom of the limiting rod 56 stuck inside the limiting groove 57, so as to make the support plate 54 form an inclined angle. And according to the position of the user, the support plate 54 can be rotated around the telescopic rod 52 to make the support plate 54 tilt towards the user. When the user uses an electronic product to work or study, place the electronic product against the support plate 54, so that the electronic product is as level with the user's line of sight as possible, reducing the cervical spine problems caused by looking down for a long time.

[0022] Working principle: When the placement area on the surface of the table board 2 is not enough, the folding frame 3 can be used as a storage rack to increase the available space of the lifting table. And when the usable area on the surface of the table board 2 is not enough and office work or study needs to be carried out, the folding frame 3 can be rotated to directly above the table board 2, so that multiple folding plates 32 form a temporary desktop. When working or studying through the table board 2, stand the folding frame 3 on one side of the top of the table board 2 to facilitate the adjustment of the angle adjustment device 5. After pulling out the support plate 54 from the inside of the installation groove 4, insert the limiting rod 56 into different limiting grooves 57 to adjust the inclined angle of the support plate 54, so that the electronic product or book viewed by the user can be level with the user. Pull the movable plate 51 upward to make the support plate 54 located above the table board 2, which is convenient for the support plate 54 to rotate and make the support plate 54 tilt towards the direction where the user is located.

[0023] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
