[0002] Primary school education is the beginning of school education and is an important part of basic education. The tables used for classroom learning are collectively called desks, which are extremely important auxiliary tools in the educational process. Desks are usually divided into solid wood desks, lifting desks and rubber-plastic desks, and desks are usually equipped with table holes to facilitate students to place various learning supplies and books.

[0003] When a desk is needed for assistance during study, the desk legs are first placed in a designated location, then the study supplies are stored in the desk frame, and then the books are spread out on the desk to assist people in study. However, in the process of using the desk, in order to find the materials needed for study more quickly, people will spread out books, test papers, exercise books and other materials on the desk at the same time, but the area on the desk used to place books and study supplies is fixed, and people usually use bolts to install extension plates on both sides of the desk to increase the area of ​​the desk, but this method of increasing the area of ​​the desk is relatively cumbersome, and it is necessary to repeatedly turn multiple sets of bolts to fix the extension plates, which is not convenient enough, thus affecting the use of the desk. Utility Model Content

[0004] The purpose of the utility model is to provide a desk with a limiting structure to solve the problem that when the desk is used, the method of increasing the desktop area is relatively cumbersome, and multiple sets of bolts need to be repeatedly turned to fix the extension plate, which is not convenient enough and cannot meet people's usage needs.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 and Figure 3 The utility model provides a technical solution: a desk with a limiting structure, comprising a desk frame 1, a desktop 2 and a table leg 3, the top of the outer wall of the desk frame 1 is butted with the desktop 2, and the table leg 3 is arranged below the desk frame 1, and the outer wall of the desk frame 1 is provided with an auxiliary mechanism 4, the auxiliary mechanism 4 comprises a rotating seat 41, a guide member 42, an extension plate 43, a fixing member 44, a limiting rod 45, a guide pin 46 and a spring 47, the two sides of the bottom end of the desktop 2 are butted with the rotating seat 41; the inside of the rotating seat 41 is connected with the guide member 42, and the outer wall of the guide member 42 is fixedly connected with the extension plate 43; A fixing part 44 is slidably connected inside the extension plate 43, and a guide pin 46 is slidably connected inside the fixing part 44; a spring 47 is sleeved on the outer wall of the guide pin 46, and the side of the fixing part 44 away from the guide pin 46 is rotatably connected to the limit rod 45; a limit hole that is connected to the limit rod 45 is provided on the side of the table frame 1 close to the fixing part 44, and a fixing cavity that is connected to the fixing part 44 is provided on the side of the table frame 1 close to the extension plate 43; both sides of the guide pin 46 are connected to the extension plate 43, and an elastic telescopic mechanism is formed between the fixing part 44, the guide pin 46 and the spring 47.

[0024] In specific implementation, in the learning process, when the desk is used for assistance, in order to place more books and learning supplies on the desktop 2, when it is necessary to increase the placement area of ​​the desktop 2, because the rotating seat 41 is connected to the guide member 42, and the guide member 42 is connected to the extension plate 43, the extension plate 43 is first manually moved to make the guide member 42 rotate along the rotating seat 41 until the extension plate 43 is in a horizontal state, and then the spring 47 is reset to drive the fixing member 44 to move, and at this time the fixing member 44 moves along the guide pin 46, and then the movement of the fixing member 44 is guided by the guide pin 46;

[0025] Until the fixing member 44 is connected to the desktop 2, and because the fixing member 44 is rotatably connected to the limiting rod 45, the limiting rod 45 is rotated to connect with the desktop 2, thereby limiting the extension plate 43 to prevent the extension plate 43 from moving at will, and then the extension plate 43 can be unfolded to increase the area for placing books without repeatedly rotating multiple sets of bolts, thereby facilitating the limiting of the position and increasing the placement area during the use of the desk;

[0026] When the extension plate 43 needs to be moved to save space, the limiting rod 45 is first manually rotated to disconnect it from the desktop 2, and then the fixing member 44 is manually moved. At this time, the fixing member 44 moves the extrusion spring 47, causing the spring 47 to deform until the fixing member 44 is disconnected from the desktop 2, thereby canceling the limit on the extension plate 43, and then rotating the extension plate 43 to a vertical state, thereby saving space and making it convenient for people to pass by on both sides of the desktop 2.

[0027] See also Figure 1 , Figure 4 and Figure 5 It can be seen that a fixing mechanism 5 is provided on the outer wall of the table leg 3, and the fixing mechanism 5 includes a limit seat 51, an iron guide block 52, a magnetic strip 53, a threaded pin 54 and a fixing pin 55, and an iron guide block 52 is welded to the bottom end of the table frame 1; the top end of the table leg 3 is docked with the limit seat 51, and the outer wall of the limit seat 51 is fixedly connected with the magnetic strip 53; the inner part of the limit seat 51 is threadedly connected with a threaded pin 54, and fixing pins 55 are connected on both sides of the outer wall of the threaded pin 54; the fixing pin 55 is slidably connected to the limit seat 51, a threaded hole docking with the threaded pin 54 is opened in the middle of the outer wall of the iron guide block 52, and a fixing hole docking with the fixing pin 55 is opened on the side of the iron guide block 52 close to the threaded pin 54.

[0028] In specific implementation, when the desk is used for assistance during learning, in order to save space, when the desk needs to be disassembled for storage, because the desk frame 1 is connected to the iron guide block 52, and the desk leg 3 is connected to the limit seat 51, the threaded pin 54 is manually rotated first, because the threaded pin 54 is connected to the fixed pin 55, the threaded pin 54 squeezes the fixed pin 55 when it moves, and then the threaded pin 54 drives the fixed pin 55 to move together when it moves;

[0029] Until the threaded pin 54 and the fixing pin 55 are both disconnected from the iron guide block 52, and then the fixing of the iron guide block 52 is cancelled, at this time people move the desk frame 1, so that the iron guide block 52 is disconnected from the limit seat 51, and then the desk frame 1 and the table legs 3 are separated and stored, so as to prevent the desk frame 1 and the table legs 3 from occupying too much space together, so as to facilitate the storage during the use of the desk;

[0030] When the desk needs to be assembled, first connect the iron guide block 52 with the limit seat 51. At this time, the iron guide block 52 and the magnetic strip 53 are magnetically connected, thereby limiting the desk frame 1. Since the threaded pin 54 and the limit seat 51 are threadedly connected, the threaded pin 54 is then manually rotated to drive the fixing pin 55 to move together until the threaded pin 54 and the fixing pin 55 are both connected to the iron guide block 52, and then the iron guide block 52 is fixed to prevent it from moving, thereby completing the assembly of the desk.

[0031] To sum up, when the desk with a limiting structure is used, the table legs 3 are first placed in the designated location, then the school supplies are stored in the table frame 1, and then the books are spread flat on the table top 2, so that people can study with the help of the desk. This is the prior art and will not be elaborated on here. The extension plate 43 is limited by the auxiliary mechanism 4 to prevent the extension plate 43 from moving at will, and then the extension plate 43 can be unfolded to increase the area for placing books without repeatedly turning multiple sets of bolts. The iron guide block 52 is cancelled by the fixing mechanism 5, so that people can disconnect the iron guide block 52 from the limiting seat 51, and then the table frame 1 and the table legs 3 are separated for storage, so as to prevent the table frame 1 and the table legs 3 from occupying too much space together. The contents not described in detail in this description belong to the prior art known to professional and technical personnel in this field.
