The top of the lifting mechanism is fixedly connected with a rotating shaft 7, which provides a rotating base in the vertical direction for the subsequent structure, thereby facilitating folding operation of the whole learning desk.
[0034] The outer wall of the rotating shaft 7 is rotatably connected with a plurality of rotating piles 8, and the top of each rotating pile 8 is fixedly connected with a table board 9. The rotating pile 8 is used to connect the rotating shaft 7 and the table board 9, so that the table board 9 can rotate around the rotating shaft 7 as the center to facilitate adjustment of the angle of the table board 9 in the vertical direction, so as to fold the whole table board 9. The bottom of the table board 9 is fixedly connected with a folding mechanism, and the design of the folding mechanism enables the learning desk to fold the table board 9 when not in use or when storage and transportation are needed, thereby reducing the occupied space and facilitating storage and transportation. The proximal side of each supporting leg 1 is fixedly connected with a supporting mechanism, which can further enhance the connection stability between the supporting legs 1 when the learning desk is unfolded and used, prevent the supporting legs 1 from being spread outward or deformed due to external force, and improve the structural strength and anti-toppling ability of the whole learning desk.
[0035] The folding mechanism comprises two connecting piles 13, the top of the two connecting piles 13 is fixedly connected to the bottom of the table plate 9, and the connecting piles 13 are used to transmit the weight and force of the table plate 9 to other parts of the folding mechanism. The proximal side of the two connecting piles 13 is fixedly connected with a connecting shaft 14, the connecting shaft 14 penetrates through the two connecting piles 13, thereby providing a rotating basis and a supporting basis for the subsequent folding structure. The outer wall of the connecting shaft 14 is detachably connected with two hooks 12, the hooks 12 can be conveniently hung on the connecting shaft 14, and can be detached and installed as needed, so that the hooks 12 are hung on the outer side of the connecting shaft 14 after the entire learning desk is unfolded, so that the gravity and force of the entire table plate 9 are transmitted to the subsequent structure through the connecting shaft 14 and the hooks 12, thereby providing additional supporting force for the entire table plate 9. The outer wall of the hook 12 is fixedly connected with a telescopic rod 11, the telescopic rod 11 is used to connect the connecting shaft 14 and the subsequent structure, and transmit the stress received by the connecting shaft 14 to the subsequent structure, thereby performing stable supporting action. The other end of the two telescopic rods 11 is rotatably connected with a fixed column 10, through the design of the fixed column 10 and the telescopic rod 11, the entire learning desk forms a stable triangular supporting structure after being unfolded, thereby enhancing the pressure that the table plate 9 can withstand, and when the entire learning desk needs to be folded, the hooks 12 are removed, and the telescopic rod 11 is shortened, so that the telescopic rod 11 naturally falls down, thereby enabling the entire table plate 9 to rotate around the rotating shaft 7 as the center, so as to achieve the purpose of convenient folding and storage.
[0036] The lifting mechanism comprises two fixed cylinders 3, the bottom of the fixed cylinder 3 is fixedly connected to the top of the supporting leg 1, the fixed cylinder 3 provides a stable shell and supporting structure for the lifting mechanism, and the internal space is used to accommodate subsequent lifting components. The inner wall of the fixed cylinder 3 is slidably connected with a lifting plate 4, the two ends of the rotating shaft 7 are fixedly connected to the top of the two lifting plates 4, and the lifting plate 4 can slide up and down along the inner wall in the fixed cylinder 3, thereby realizing the height adjustment function of the table plate 9. The top of the lifting plate 4 is in contact with the proximal side of the two rotating piles 8, thereby further enhancing the connection stability between the table plate 9 and the lifting mechanism. In the rotating and lifting process of the table plate 9, the close contact between the rotating piles 8 and the lifting plate 4 can effectively transmit the force and torque, thereby avoiding loosening or displacement.
[0037] The outer side of the fixed cylinder 3 is slidingly connected with a sliding ring 6, the two ends of the fixed column 10 are respectively fixedly connected to the outer walls of the two sliding rings 6 on the same side, the sliding ring 6 plays a role of fixing the lifting position of the lifting plate 4 and the supporting angle of the whole supporting structure, when the lifting plate 4 rises or falls to the corresponding height, the sliding ring 6 should also rise and fall synchronously with the lifting plate 4, so as to drive the fixed column 10 to rise and fall, and because the position of the sliding ring 6 corresponds to the bottom of the lifting plate 4, that is, the distance between the fixed column 10 and the rotating shaft 7 does not change during the lifting process, so that the folding mechanism always maintains stability during the whole lifting process, thereby continuously providing stable supporting force for the table plate 9. The inside of the sliding ring 6 is threadedly connected with a fixed pin 19, the outside of the fixed cylinder 3 is provided with a plurality of through grooves 5, the position of the whole lifting plate 4 is fixed by inserting the fixed pin 19 into the through groove 5, so that the lifting plate 4 can be fixed after lifting, so as to ensure the stability of the whole table plate 9. The outside of the fixed pin 19 is threadedly connected to the inside of the through groove 5, the outside of the fixed pin 19 is threadedly connected to the bottom of the lifting plate 4, in use, the lifting plate 4 rises and falls in the vertical direction, when it is lifted to the appropriate position, the sliding ring 6 is moved to the corresponding position, and then the fixed pin 19 is screwed into the through groove 5, so as to fix the sliding ring 6 and the lifting plate 4, so as to prevent the inconvenience caused by the automatic falling of the lifting plate 4 during the use of the learning table.
[0038] Referring to Figures 1 to 3The supporting mechanism comprises a plurality of steps 2, both ends of the steps 2 are fixedly connected to the proximal sides of the two legs 1 respectively, the steps 2 serve to increase the contact area between the bottom of the study desk and the ground, disperse the pressure of the whole study desk on the ground, and thus improve the stability of the study desk when placed. The proximal sides of the two fixed cylinders 3 are fixedly connected with supporting columns 15, the supporting columns 15 serve to transmit the lateral stress borne by the two fixed cylinders 3, and thus ensure the stability of the two fixed cylinders 3. The outer wall of the supporting column 15 is fixedly connected with two sleeves 16, both distal sides of the sleeves 16 are fixedly connected with two supporting rods 17, the other ends of the supporting rods 17 are fixedly connected to the outer wall of the fixed cylinder 3, and serve to bear the stress borne by the whole study desk in the horizontal direction, when the study desk is subjected to a force in the horizontal direction, the supporting rods 17 transmit the force to the sleeves 16 and the fixed cylinder 3 through the rigid structure of the supporting rods 17, and thus prevent the fixed cylinder 3 from being displaced or deformed in the horizontal direction, and thus ensure the stability of the whole structure of the study desk and prevent the study desk from falling. The outer wall of the sleeve 16 is fixedly connected with supporting rods 18, the other ends of the two supporting rods 18 are fixedly connected to the top of one of the steps 2, and serve to bear the stress borne by the whole study desk in the vertical direction, when a heavy object is placed on the study desk, the gravity of the heavy object is transmitted to the ground through the table plate 9, the leg 1 and other components, and in the process, the supporting rods 18 can share part of the pressure, reduce the burden of the leg 1 and the step 2, and also enhance the carrying capacity of the whole supporting mechanism in the vertical direction.
[0039] Working principle: when it is needed to fold and store the study desk, first, the fixing pin 19 is unscrewed from the through slot 5 of the fixed cylinder 3 and the bottom of the lifting plate 4, the fixing of the lifting plate 4 and the sliding ring 6 is released, the lifting plate 4 is lowered due to the action of gravity, and thus the height of the whole table plate 9 is reduced. Then, the hook 12 is removed from the connecting shaft 14, and the telescopic rod 11 is shortened, so that the telescopic rod 11 naturally hangs down, at this time, part of the supporting structure of the table plate 9 is released. Then, the table plate 9 is rotated around the rotating shaft 7, and the rotating pile 8 rotates with the table plate 9, since the fixed column 10 is connected with the telescopic rod 11 and the two ends of the fixed column 10 are connected with the sliding ring 6, the rotation of the table plate 9 drives the synchronous movement of the fixed column 10 and the sliding ring 6, so that the whole folding mechanism adjusts the position and angle following the rotation of the table plate 9, and thus the purpose of folding the table plate 9 is achieved, the occupied space of the study desk is reduced, and the storage and transportation are facilitated. After folding is completed, the components remain in the corresponding folded position, and wait for the next unfolding and use.
[0040] When the learning desk is in the unfolded use state, if affected by external force, in the horizontal direction, the external force will drive the fixed cylinder 3 to have a displacement tendency, at this time, the support rod one 17 connected with the fixed cylinder 3 will transmit the force borne by the fixed cylinder 3 to the sleeve 16 and the support column 15 through the rigid structure of the support rod one 17, so that the approximately triangular structure formed by the sleeve 16, the support rod one 17 and the fixed cylinder 3 plays a role to prevent the displacement and deformation of the fixed cylinder 3 in the horizontal direction, thereby keeping the overall structure stable and preventing the learning desk from falling over; in the vertical direction, the gravity of the weight placed on the table plate 9 is transmitted through the table plate 9 and the supporting leg 1 in turn, part of the force will drive the pedal 2 to generate pressure, and the support rod two 18 connected between the pedal 2 and the sleeve 16 will share this part of the pressure, thereby reducing the burden of the pedal 2 and the supporting leg 1 and enhancing the carrying capacity of the supporting mechanism in the vertical direction, at the same time, the support column 15 transmits and disperses the transverse stress borne by the two fixed cylinders 3, thereby ensuring the stability of the fixed cylinder 3 and achieving the stable support of the learning desk against falling over.
