[0024] 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.

[0025] like Figure 1-5 As shown:

[0026] A student desk designed to prevent myopia, comprising a desk body 101;

[0027] There are two sets of mounting brackets 102, which are installed on both sides of the desk body 101. The mounting brackets 102 are fixed to the side of the desk body 101 by screws.

[0028] The bracket rod 103 is installed on the mounting base 102;

[0029] The connecting rod 104 is positioned between the two sets of support rods 103.

[0030] In this implementation plan: The student anti-myopia desk provides a learning platform for students during use. Support rods 103 are installed on the mounting bases 102 on both sides of the desk body 101, and a connecting rod 104 is installed between the two sets of support rods 103 to form a guardrail. This effectively prevents students from studying by leaning over the desk body 101 or being too close to it. This design guides students to maintain correct viewing distance and reading posture, reduces prolonged close-range eye use, effectively reduces the risk of myopia, improves the efficiency of the device, and meets practical application needs.

[0031] Furthermore;

[0032] In an optional embodiment, a folding locking member 2 is installed between the mounting base 102 and the support rod 103. The folding locking member 2 includes a rectangular groove formed on the end surface of the support rod 103 and a guide rod 201 disposed in the rectangular groove. The guide rod 201 and the support rod 103 are fixedly installed. A locking block 203 is also provided in the rectangular groove. The locking block 203 can slide on the surface of the guide rod 201 through a movable groove. A spring 202 is wound around the surface of the guide rod 201. The two ends of the spring 202 are fixedly connected to the locking block 203 and the support rod 103, respectively. A first locking groove 204 and a second locking groove 205 adapted to the locking block 203 are formed on the surface of the mounting base 102. The locking block 203 is inserted into the first locking groove 204 or the second locking groove 205 formed in the mounting base 102 for folding and locking the support rod 103 and the mounting base 102. The support rod 103 is rotatably connected to the mounting base 102 through a bearing.

[0033] In this embodiment: a folding locking member 2 is installed between the mounting base 102 and the support rod 103. This folding locking member 2 is used to fold and lock the support rod 103 and the mounting base 102. The specific operation is as follows: Figure 1 and 5 As shown, when the guardrail is not in use, it can be folded to save space. The sliding locking block 203 has anti-slip teeth on its outer surface. These anti-slip teeth can increase the friction between the fingers and the locking block 203, thereby improving the effect of the sliding locking block 203. The user pushes the locking block 203 to slide it on the guide rod 201 and compresses the spring 202 until the locking block 203 is disengaged from the first locking groove 204 opened in the mounting base 102, thereby releasing the connection lock between the support rod 103 and the mounting base 102.

[0034] Subsequently, the user can rotate the bracket rod 103. Since the bracket rod 103 is rotatably connected to the mounting base 102 through the bearing, the user can turn the bracket rod 103 by a certain angle to make the locking block 203 correspond to the second locking groove 205. The spring 202, which is in a compressed state, will rebound and drive the locking block 203 to insert into the second locking groove 205, thereby relocking the connection between the bracket rod 103 and the mounting base 102.

[0035] During this process, the support rod 103 drives the connecting rod 104 and other components to fold below the main body of the desk 101. This allows the connecting rod 104 to be folded from above the main body of the desk 101 to below, thus saving space and further improving the overall usability and space utilization of the device.

[0036] Furthermore;

[0037] In an optional embodiment, the connecting rod 104 is covered with a sponge sleeve 105.

[0038] In this embodiment, a sponge sleeve 105 is installed on the connecting rod 104, which can act as a buffer when people accidentally bump into the connecting rod 104, reduce the impact force, reduce the risk of injury, and enhance the practicality and safety of the overall structure.

[0039] Furthermore;

[0040] In an optional embodiment, a snap-fit ​​element 3 is provided between the connecting rod 104 and the support rod 103. The snap-fit ​​element 3 is used to lock the connection between the connecting rod 104 and the two sets of support rods 103. The snap-fit ​​element 3 includes a housing seat 301 fixed at both ends of the connecting rod 104 and a rotating disk 302 rotatably mounted in the inner cavity of the housing seat 301 via bearings. The inner cavity of the housing seat 301 is also provided with a threaded post 303. Two sets of telescopic sleeve rods 304 are fixedly installed between the threaded post 303 and the housing seat 301. A locking post 305 is fixedly installed on the side of the threaded post 303 away from the telescopic sleeve rod 304. One end of the support rod 103 is provided with a slot 306 that matches the locking post 305. The rotating disk 302 is threadedly connected to the threaded post 303 through a threaded hole. A strip-shaped through groove is provided on the surface of the housing seat 301 near the rotating disk 302. Part of the outer surface of the rotating disk 302 extends out from the strip-shaped through groove and is exposed to the outside of the housing seat 301.

[0041] In this embodiment: two sets of support rods 103 are connected to the connecting rod 104 through snap-fit ​​parts 3. The outer part of the rotating disk 302 is provided with anti-slip teeth to facilitate user rotation. When the user rotates the rotating disk 302, since the rotating disk 302 is threadedly connected to the threaded column 303 and the threaded column 303 is rotated and limited by two sets of telescopic sleeve rods 304, rotating the rotating disk 302 can cause the threaded column 303 to move laterally. The movement of the threaded column 303 then drives the locking column 305, so that it can be inserted into the slot 306 of the support rod 103, thereby realizing the locking connection between the connecting rod 104 and the support rod 103.

[0042] By rotating the rotary disk 302 in the opposite direction, the threaded post 303 can be driven to exit from the slot 306 along with the locking post 305. This facilitates the disassembly and assembly of the connecting rod 104 and the bracket rod 103. In addition, it also makes it easier to disassemble and clean the sponge sleeve 105 on the surface of the connecting rod 104, thus improving the overall practicality of the device.

[0043] It should be noted that the outer diameter of the housing 301 is matched with the outer diameter of the connecting rod 104, and the length of the sponge sleeve 105 is matched with the length of the connecting rod 104. Meanwhile, the rotating disk 302 has a convex structure design, and part of the outer surface of the rotating disk 302 is rotatably connected to the housing 301 through bearings.

[0044] The working principle and usage process of this utility model: This anti-myopia desk for students provides a learning platform for students during use. Support rods 103 are installed on the mounting bases 102 on both sides of the desk body 101. Connecting rods 104 are installed between the two sets of support rods 103 via snap-fit ​​parts 3, forming a guardrail. This effectively prevents students from studying while lying on or too close to the desk body 101. This design guides students to maintain correct viewing distance and reading posture, reducing prolonged close-range eye use and effectively lowering the risk of myopia. Sponge sleeves 105 are installed on the connecting rods 104 to cushion impacts when people accidentally bump into them, reducing the risk of injury and enhancing the overall practicality and safety of the structure.

[0045] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model 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.
