When the positioning plate 909 is not needed, the positioning strip 914 is squeezed away from the groove 913 by the fifth spring 912, and then the positioning strip 914 is arranged on the side of the positioning plate 909 away from the notch 908, so that the positioning plate 909 can be received inside the notch 908.
[0027] Working principle: when using desks and chairs for naps, manually rotate the hinged backrest 3 and the hinged footrest 7 set on one side of the table to the appropriate position, so that you can lie on the chair during lunch break, thus avoiding lying on the table for lunch break, which to a certain extent affects the physical development of children during lunch break. When using the support device 8, slide the connecting block 814 into the inside of the connecting groove 809, so that it is convenient to set the limit plate 807 at the bottom of the support bar 806. After the connecting block 814 slides to the inner wall of the connecting groove 809, the first spring 813 squeezes the baffle 811 in the direction away from the storage groove 810, thereby making the baffle 811 The connecting block 814 is arranged on a side away from the connecting groove 809, so that the connecting block 814 can be restricted inside the connecting groove 809, and the limiting plate 807 is arranged at the bottom of the support bar 806. The rotating rod 802 is manually controlled to rotate, so that the support bar 806 and the limiting plate 807 are vertical to the ground, and then the threaded rod 804 is manually controlled to rotate, so that the bottom of the limiting plate 807 is squeezed on the ground, so that the backrest 3 can be well supported by the limiting plate 807 and the support bar 806. When the limiting plate 807 is not in use, the limiting plate 807 is manually slid to the middle of the two limiting bars 815, and then the second spring 818 is used to adjust the position of the limiting plate 807. The limiting sleeve 819 is squeezed in the direction close to the limiting plate 807, and then the limiting sleeve 819 is sleeved on one side of the top of the limiting plate 807, so that the limiting plate 807 can be stored. When using the connecting device 9, the fixing frame 902 is manually slid out of the interior of the positioning groove 901. When the fixing frame 902 slides to the appropriate position, the bolt 904 is manually controlled to rotate, so that the bolt 904 is squeezed on one side of the fixing frame 902, which makes it easy to limit the fixing frame 902 to the interior of the positioning groove 901, and then the fixing frame 902 is sleeved on the surface of the bottom of the connecting frame 1, so that the connecting frame 1 can be limited to one side of the support frame 5. The fourth spring 911 presses the positioning plate 909 in the direction away from the notch 908, so that the positioning plate 909 slides into the inside of the positioning groove 905. When the positioning plate 909 is not needed, the fifth spring 912 presses the positioning bar 914 in the direction away from the groove 913, and then the positioning bar 914 is set on the side of the positioning plate 909 away from the notch 908, so that the positioning plate 909 can be stored inside the notch 908. When the connecting device 9 is not in use, the third spring 907 pulls the fixing frame 902 toward the inner wall of the positioning groove 901, so that the fixing frame 902 can be stored inside the positioning groove 901.
[0028] It should be noted that all damping rods in this case are retractable dampers that can absorb energy during the retraction and extension process.
[0029] The reclining desk and chair also includes a first cooling and cleaning component, which includes a cooling structure and a cleaning structure. The cooling structure is arranged on the side of the footrest facing the connecting frame. The cooling structure includes a connecting part, a power output part, a rotating part, an extension end and a fan blade.
[0030] Specifically, the connecting part is arranged above the side of the pedal, and the connecting part is made of soft materials such as silicone or rubber. The power output part and the connecting part are fixedly connected, the rotating part is located on the power output part, and the extending end is located on the end of the rotating part away from the power output part. There are multiple fan blades, and the multiple fan blades are evenly arranged around the periphery of the extending end, and the multiple fan blades are all facing the connecting frame.
[0031] The cleaning structure is slidably connected to the side of the pedal away from the cooling structure. The cleaning structure includes a cleaning body and a cleaning adsorption film provided on the cleaning body. The cleaning body and the pedal are slidably connected. The position of the cleaning body and the cooling structure are staggered. For example, if the cooling structure is located on the left, the position of the cleaning body is located on the right. If the cooling structure is located on the right, the position of the cleaning body is located on the left. The cleaning adsorption film is located on the surface of the cleaning body. The manner in which the cleaning adsorption film is provided on the cleaning body includes but is not limited to coating or bonding, and the cleaning adsorption film has stickiness. Specifically, one of the cleaning body and the pedal is provided with a sliding groove, and the other of the cleaning body and the pedal is provided with a sliding rail. The sliding rail is used to cooperate with the sliding groove, and the sliding rail is slidably located in the sliding groove.
[0032] In one embodiment, a wire body is provided on the rotating part, one end of the wire body is connected to the rotating part, and the other end of the wire body is fixedly connected to the surface of the cleaning body. It can be understood that when a user sits on the reclining desk and chair and the cooling structure is in operation, multiple condensation airflows are formed around the cooling structure and blown toward the connecting frame to reduce the temperature around the connecting frame, thereby cooling the user and improving the user's comfort. At the same time, when the cooling structure is in operation, as the rotating part rotates, the wire body on the rotating part is tightened, thereby causing the cleaning body to slide and gradually approach the cooling structure. In the process of the cleaning body approaching the cooling structure, the cleaning adsorption film can be attached to the footrest to absorb dust on the footrest. In addition, the cleaning adsorption film can also be provided with the activated carbon, and the external air can be purified by providing a plurality of the activated carbons.
[0033] In one embodiment, the power output member can be electrically connected to the controller, and the controller can control the turning on or off of the power output member, the increase or decrease of the output power, the stop or continuation, so as to meet different needs of users.
[0034] In one embodiment, the reclining desks and chairs further include a second cooling and cleaning component, which is disposed on the side of the storage frame, and the second cooling and cleaning component has the same structure as the second cooling and cleaning component. On the one hand, the second cooling and cleaning component can reduce the surrounding temperature to cool the user and improve the user's comfort. On the other hand, during the cooling process, the second cooling and cleaning component can also adsorb the dust on the side of the storage frame.
