DETAILED DESCRIPTION
[0025] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.
[0026] Example:
[0027] As attached Figure 1 To Attachment Figure 7 As shown:
[0028] The utility model provides a multifunctional integrated assembled desk device, comprising a base 1; a seat 2 is arranged on the top of the base 1, a writing board 3 is arranged on one side of the outer end of the seat 2, a sleeve 4 is arranged on one side of the top of the base 1, and a crankshaft rod 5 is arranged on the top of the sleeve 4.
[0029] Among them, a rotating groove 401 is opened inside the sleeve 4, a magnet a402 is set at the bottom of the rotating groove 401, the bottom of the crankshaft rod 5 is slidably connected with the inside of the rotating groove 401, a magnet b503 attracted to the magnet a405 is set at the bottom of the crankshaft rod 5, a limiting groove 403 is opened on the inner wall of the rotating groove 401, a limiting ring 504 is sleeved near the bottom of the crankshaft rod 5, and the limiting ring 504 is slidably connected with the inside of the limiting groove 403.
[0030] When group teaching is required in the classroom, the crankshaft rod 5 at the bottom of the writing board 3 is grasped and lifted upwards, and the crankshaft rod 5 drives the magnet b503 at the bottom to separate the magnet b503 from the magnet a402 at the bottom of the rotating groove 401, so that the crankshaft rod 5 can rotate inside the rotating groove 301, and then the writing board 3 is driven to rotate by rotating the crankshaft rod 5, so that the writing boards 3 of multiple members can be quickly combined to achieve rapid grouping and facilitate discussion among group members. After the position of the writing board 3 is adjusted, the writing board 3 is loosened, and the writing board 3 and the crankshaft rod 5 move downward under their own gravity, so that the magnet b503 and the magnet a402 at the bottom of the crankshaft rod 5 are attracted to each other, thereby fixing the position of the writing board 3 and preventing the writing board 3 from rotating during use, thereby achieving rapid adjustment of the classroom teaching format without moving tables and chairs, reducing loss time, and thus meeting different application scenarios, realizing multiple uses of one table, and improving resource utilization.
[0031] When the writing board 3 is lifted to separate the magnet b502 at the bottom of the crankshaft rod 5 from the magnet a402, the crankshaft rod 5 drives the limiting ring 504 to move upward inside the limiting groove 403 and supports the top surface inside the limiting groove 403. Then, when the writing board 3 is rotated, the crankshaft rod 5 drives the limiting ring 504 to rotate inside the limiting groove 403, and the limiting groove 403 and the limiting ring 504 prevent the crankshaft rod 5 from being directly separated from the rotating groove 401 when the crankshaft rod 5 is lifted, resulting in the need to reinsert the crankshaft rod 5 into the rotating groove 401. Since the crankshaft rod 5 is a special-shaped rod, the crankshaft rod 5 will not collide with the seat 2 when the writing board 3 is rotated, thereby preventing the writing board 3 from being unable to rotate 306°.
[0032] Among them, a plurality of storage grooves 103 are opened on the upper surface of the base 1, and a universal wheel 104 is installed at the bottom of the base 1. The universal wheel 104 installed at the bottom of the base 1 can facilitate the movement of the seat 2 and the writing board 3. At the same time, the storage grooves 103 opened on the upper surface of the base 1 can be used to place personal items, thereby improving the utilization rate of the space.
[0033] Among them, a mounting plate 301 is provided at the bottom of the writing board 3, a fixing plate 501 is provided at the top of the crankshaft rod 5, mounting bolts 502 are provided on both sides of the bottom of the fixing plate 501, nuts 302 are provided on both sides of the top of the mounting plate 301, through holes are opened on both sides of the mounting plate 301 and the fixing plate 501, the mounting bolts 502 pass through the through holes and are connected with the internal threads of the nuts 302, and the mounting bolts 502 on both sides of the bottom of the fixing plate 501 are respectively screwed to separate the mounting bolts from the threads 301 on both sides of the top of the mounting plate 301, and then the mounting bolts 502 are taken out from the through holes opened on both sides of the mounting plate 301 and the fixing plate 501, so that the writing board 3 can be disassembled from the crankshaft rod 5, so as to facilitate the cleaning of the writing board 3.
[0034] Among them, pen grooves 303 are opened on both sides of the upper surface of the writing board 3, and an anti-drop rubber sleeve 304 is provided on the outside of the writing board 3. When using the writing board 3, the pen groove 303 opened on its upper surface can be used to place a writing pen, and the anti-drop rubber sleeve 304 provided on the outside of the writing board 3 can prevent the writing pen from rolling off the board surface when it is not placed in the pen groove 303.
[0035] Among them, a gas pressure rod 101 is provided between the base 1 and the seat 2, and an adjustment rod 102 is provided on one side of the gas pressure rod 101. The gas pressure rod 101 between the base 1 and the seat 2 can be used to adjust the height of the seat 2 through the adjustment rod 102, so that members of different heights can use it in a comfortable sitting posture. The gas pressure rod 101 is composed of a pressure tube, a piston, a piston rod and a number of connecting parts. Its basic principle is that it is filled with high-pressure nitrogen. Since a through hole is provided inside the piston, the gas pressure at both ends of the piston is equal, and the cross-sectional areas on both sides of the piston are different. One end is connected to the piston rod and the other end is not. Under the action of gas pressure, pressure is generated toward the side with a smaller cross-sectional area, that is, the elastic force of the gas pressure rod, and then the pressure difference on both sides of the piston head is used to realize the lifting process, and the external force is used to offset the pressure difference to realize the lowering process.
[0036] The specific usage and function of this embodiment are as follows:
[0037] When group teaching is required in the classroom, the crankshaft rod 5 at the bottom of the writing board 3 is grasped and lifted upward, and the crankshaft rod 5 drives the magnet b503 at the bottom to separate the magnet b503 from the magnet a402 at the bottom of the rotating groove 401, so that the crankshaft rod 5 can rotate inside the rotating groove 301, and then the writing board 3 is driven to rotate by rotating the crankshaft rod 5, so that the writing boards 3 of multiple members can be quickly combined to achieve rapid grouping and facilitate discussion among group members. After the position of the writing board 3 is adjusted, the writing board 3 is loosened, and the writing board 3 and the crankshaft rod 5 move downward due to their own gravity, so that the magnet b503 and the magnet a402 at the bottom of the crankshaft rod 5 are attracted to each other, thereby fixing the position of the writing board 3 and preventing the writing board 3 from rotating during use, thereby achieving rapid adjustment in the classroom. In the form of a class, there is no need to move tables and chairs, which reduces loss time and meets different application scenarios. When the writing board 3 is lifted to separate the magnet b502 at the bottom of the crankshaft rod 5 from the magnet a402, the crankshaft rod 5 drives the limiting ring 504 to move up inside the limiting groove 403 and supports the top surface inside the limiting groove 403. Then, when the writing board 3 is rotated, the crankshaft rod 5 drives the limiting ring 504 to rotate inside the limiting groove 403, and the limiting groove 403 and the limiting ring 504 are used to prevent the crankshaft rod 5 from being directly separated from the rotating groove 401 when the crankshaft rod 5 is lifted, resulting in the need to reinsert the crankshaft rod 5 into the rotating groove 401. Since the crankshaft rod 5 is a special-shaped rod, the crankshaft rod 5 will not collide with the seat 2 when the writing board 3 is rotated, thereby preventing the writing board 3 from being unable to rotate 306°.
