DETAILED DESCRIPTION
[0024] The utility model is further described below with reference to the accompanying drawings and embodiments. Example 1
[0025] This embodiment provides a stable student desk. Figure 1-Figure 4As shown, the supporting structure includes connecting members 2 fixed on the front and rear sides of the left and right sides below the desktop 1, a supporting arm 2-1 is provided on one side of the connecting member 2, the cross section of the supporting arm 2-1 is H-shaped, a supporting block 2-2 is provided in the middle of the supporting arm 2-1, a U-shaped elastic block 2-3 is provided above the supporting block 2-2, cross beams 3 are provided on both sides below the desktop 1, and both ends of the cross beam 3 are sleeved outside the supporting arms 2-1 of the connecting member 2 on the front and rear sides of the same side, and a table leg 5 is installed below the connecting member 2.
[0026] The support arm 2-1 is provided with a stopper 2-4 at the front side of the elastic block 2-3.
[0027] The lower part of the table leg 1 is inclined outward.
[0028] A connecting plate 2-5 is fixed above the connecting member 2, a connecting hole 2-6 is opened on one side of the connecting plate 2-5, and screws pass through the connecting hole 2-6 to be fixedly connected to the desktop 1.
[0029] A second crossbeam 4 is connected between the first crossbeam 3 on both sides below the desktop 1.
[0030] A connecting block 6 is fixed to the side of the beam 1 3 , a groove 6 - 1 is provided on one side of the connecting block 6 , the end face of the beam 2 4 is embedded in the groove 6 - 1 , and the top of the connecting block 6 is fixedly connected to the desktop 1 .
[0031] The two sides of the beam 3 below the desktop 1 of the student desk are connected to the connecting piece 2. The cross section of the support arm 2-1 of the connecting piece 2 is H-shaped, which can improve the bending resistance of the support arm 2-1 to improve the load-bearing effect. An elastic block 2-3 is installed above the support block 2-2 in the middle of the support arm 2-1. The U-shaped opening of the elastic block 2-3 generates elastic force upward through the deformation of the U-shaped structure, so that the support arm 2-1 can be stuck on the inner side of one end of the beam 3, and can provide a top elastic force upward, so that the beam 3 will not collapse, and the top lifting effect is always maintained to ensure the support of the desktop 1. When disassembly is required, the stopper 2-4 blocks the elastic block 2-3, and the elastic block 2-3 can be pulled out.
[0032] The crossbeam 2 4 strengthens the connection of the supporting structure, improves the supporting effect of the table top 1, and can improve the load-bearing capacity of the table top 1. The connecting piece 2 is fixedly connected to the table top 1 by screws through the connecting holes 2-6 of the connecting plate 2-5, and the connecting block 6 can also be fixedly connected to the table top 1 by screws. The crossbeam 1 3 has a lifting effect on the table top, which can prevent the screw connection between the connecting piece 2 and the connecting block 6 and the table top 1 from loosening. The table legs 5 are tilted outward to make the supporting force inward, improve the stability of the supporting structure, and prevent the table from tipping over. Example 2
[0033] The utility model provides a large and stable student desk. Figure 3-Figure 8As shown, the difference from Example 1 is that a crossbeam 3 7 is provided at the lower middle of the table top 1, columns 8 are provided on both sides below the crossbeam 3 7, and adjusting feet 8 - 1 are provided at the bottom of the columns 8.
[0034] A connecting block 6 is fixed to the side of the beam 1 3 and the beam 3 7 , and a groove 6 is provided on one side of the connecting block 6 . The two ends of the beam 2 4 are respectively embedded in the grooves 6 - 1 of the connecting block 6 on both sides, and the top of the connecting block 6 is fixedly connected to the desktop 1 .
[0035] The outer sides of the columns 8 on both sides are wrapped with baffles 8 - 3 .
[0036] The adjusting foot 8 - 1 is connected to the bottom of the column 8 through the stud 8 - 2 .
[0037] A beam 3 7 is added below the table top 1 and supported by a column 8, so that the middle of the table top 1 can be supported when the table top 1 is lengthened. An adjustment foot 8-1 is provided at the bottom of the column 8, and the size and height of the support force of the beam 3 7 can be adjusted by rotating the adjustment foot 8-1. A plurality of beams 2 4 can be arranged between the beams 1 3 and the beams 3 7 to facilitate the arrangement and support of the table top 1, and the baffle 8-3 separates the two sides below the table top 1.
