AI Technical Summary
The main components of the existing student desks cannot provide enough space for the seat back when tilted, making it impossible for the backrest to tilt to a near-horizontal position, which affects the quality of students' lunch break.
A rotatable bracket and a fixed bracket with a split structure were designed. By rotating the rotatable bracket horizontally, the main component is made to give way to the fixed bracket, thereby allowing the seat back to be adjusted to a greater tilt angle or even laid flat.
It improves the quality of students' sleep in the seats by increasing the range of backrest tilt adjustment to meet students' needs for lunch break.

[0033] In order to keep the following description of the embodiments of the present application clear and concise, detailed descriptions of known functions and known components are omitted.
[0034] As shown in Figs. 1 to 3 The embodiments of the present application disclose a student desk, which comprises a main body component 10 and a support; the main body component 10 comprises a table plate 11 and a table hopper 12 fixed to the bottom of the table plate 11, the upper surface of the table plate 11 serves as a table top, and the table hopper 12 is used for temporarily storing articles such as textbooks.
[0035] The support is of a split structure, i.e., the support comprises a fixed support 30 and a rotatable support 20; the fixed support 30 is used for supporting on the ground, and the main body component 10 is fixed to the top of the rotatable support 20, preferably, the main body component 10 is detachably fixed to the top of the rotatable support 20.
[0036] The fixed support 30 comprises two support bottom beams 34 arranged at intervals, a first lower column 31 and a second lower column 32 arranged vertically on the two support bottom beams 34, and a first cross beam 33 connected between the first lower column 31 and the second lower column 32. Preferably, the support bottom beam 34, the first cross beam 33, the first lower column 31, and the second lower column 32 are fixed by welding. Preferably, the support bottom beam 34, the first cross beam 33, the first lower column 31, and the second lower column 32 are all made of metal pipes.
[0037] The rotatable support 20 comprises a first upper stand 21 and a second upper stand 22 arranged vertically at intervals, and a second cross beam 23 connected between the first upper stand 21 and the second upper stand 22. The interval between the first upper stand 21 and the second upper stand 22 is equal to the interval between the first lower stand 31 and the second lower stand 32. Preferably, the first upper stand 21, the second upper stand 22 and the second cross beam 23 are fixed by welding. Preferably, the first upper stand 21, the second upper stand 22 and the second cross beam 23 are all made of metal tubes.
[0038] The upper end of the first lower stand 31 of the fixed support 30 is configured with a socket, which is a blind hole with a baffle at the bottom, and the lower end of the first upper stand 21 of the rotatable support 20 is inserted into the socket, and the baffle is used to limit the insertion depth of the lower end of the first upper stand 21. In this way, the rotatable support 20 can drive the main body part 10 to rotate horizontally relative to the fixed support 30, as shown in Fig. 2 The rotatable support 20 can also drive the main body part 10 to rotate horizontally relative to the fixed support 30, as shown in Fig. 3 so that the main body part 10 completely gives up the space above the fixed support 30. The state of the rotatable support 20 at this time is referred to as the second state. In this way, the backrest of the seat can be adjusted to a larger inclination angle, for example, the backrest can be placed flat, which is beneficial to improve the sleep quality of students on the seat.
[0039] The lower end of the first upper stand 21 of the rotatable support 20 is provided with a pin hole 211, and the upper end of the first lower stand 31 of the fixed support 30 is provided with a spring pin part 41. After the rotatable support 20 is turned to the first state, the pin hole 211 of the first upper stand 21 is just opposite to the pin shaft of the spring pin part 41, and the pin shaft is inserted into the pin hole 211 under the action of the spring, thereby limiting the free rotation of the rotatable support 20. Preferably, by reasonably configuring the position of the pin hole 211, the rotatable support 20 can be fixed after being rotated horizontally relative to the fixed support 30 by 90 degrees.
[0040] The upper end of the second lower column 32 of the fixed support 30 is provided with a notch 321, and when the rotatable support 20 is turned to the second state, the lower end of the second upper column 22 of the rotatable support 20 passes through the notch 321 of the upper end of the second lower column 32 and abuts against the inner wall of the upper end of the second lower column 32. The upper end of the second lower column 32 and the lower end of the second upper column 22 are both provided with threaded holes 221, and the upper end of the second lower column 32 is provided with a jackscrew 42, and the second upper column 22 is combined with the second lower column 32 by rotating the jackscrew 42 into the two threaded holes 221, so as to limit the free rotation of the rotatable support 20 relative to the fixed support 30.
[0041] In some preferred embodiments, the fixed support 30 is further provided with a counterweight (not shown in the drawings) on the side where the second lower column 32 is located. For example, a plate-shaped counterweight can be fixed at the support bottom beam 34. The counterweight can significantly inhibit the shift of the overall center of gravity caused by the turning of the rotatable support 20 to the second state, thereby preventing the desk from falling over.
[0042] In some preferred embodiments, the upper end of the first lower column 31 is provided with a rubber sleeve 50, which is used to inhibit the shaking of the first upper column 21 relative to the first lower column 31 and reduce the wear therebetween.
