Embodiment Construction
[0017] The present invention will be described in further detail below by means of specific embodiments:
[0018] The reference signs in the drawings of the description include: desktop board 1, table cabinet 2, rack 3, support plate 4, ring gear 5, second drum 6, clockwork spring 7, sleeve 8, rotating shaft 9, first Drum 10, ratchet 11, upper gear shaft 12, transmission gear shaft 13, lower gear shaft 14, support 15, base plate 16, one-way bearing 17, table leg 18, pull bar 19.
[0019] A method for adjusting the height of a desk relates to a desk, such as figure 1 and figure 2 As shown, the desk includes table legs 18 and a desk cabinet 2 with an open top, and the table legs 18 and the desk cabinet 2 are vertically slidably connected. The top of the desk cabinet 2 is hinged with a desktop board 1 that can be covered on the top of the desk cabinet 2 . The interior of the table cabinet 2 is vertically slidably connected with a support plate 4, and a drive mechanism is prov...

The invention discloses a method for adjusting the height of a desk. The method comprises the steps that firstly, textbooks are placed on a supporting plate, the supporting plate moves downwards underthe action of the pressure of the textbooks, the supporting plate drives a rotary shaft to rotate through a sleeve, and the rotary shaft drives a first revolving drum to rotate and makes a power spring twist; secondly, when the height of the desk needs to be increased, supports are slid, so that upper gear shafts or lower gear shafts mesh with gear rings, a pawl is separated from a ratchet wheel,so that the power spring drives the first revolving drum to rotate, the first revolving drum drives the gear rings to rotate through a second revolving drum, the gear rings drive a drive gear shaft to rotate through the upper gear shafts or the lower gear shafts, so that the drive gear shaft moves upwards on racks, and a desk cabinet is made to move upwards; thirdly, the pawl is rotated, so thathe pawl makes contact with the ratchet wheel, and the first revolving drum stops rotating; fourthly, latches are inserted into corresponding latch holes, so that the height of the desk cabinet is positioned; fifthly, the supports are moved, so that the upper gear shafts and the lower gear shafts are separated from the gear rings. By means of the method, the problem that the height of the desk is inconvenient to adjust is solved.
Description
technical field [0001] The invention relates to the technical field of student desks. Background technique [0002] In daily life, the height of the legs of traditional desks is fixed, so the desktop of the desk cannot rise or fall with the needs of users, which brings a lot of inconvenience to students of different heights. There are height-adjustable desks on the market now, but the desks are generally connected by special workpieces, which requires the use of professional tools during adjustment, so that the height-adjustable desks are reduced to fixed-height desks. During the students' study time of the day, a lunch break is usually arranged at noon, so as to ensure that the students are full of energy to study in the afternoon. During the lunch break, students usually lie on their desks. However, students have different requirements for the height of the desk when they are studying and taking a lunch break, which requires the desk to be easy to operate in height adjus...
