The utility model can display relevant learning materials; can store manuscript paper, and can pull the manuscript paper placement box out of the cavity when needed; and can throw the waste paper generated during the calculation process into the waste paper collection box.

[0004] However, the application did not take into account that when children use the study table, as they grow older, they need to use it in different places in actual use, so they need to put the study table in different places and adjust the height. Therefore, giving the study table a certain degree of mobility has become an innovative solution. Utility Model Content

[0005] The purpose of this application is to provide a multifunctional study table in order to solve the above-mentioned problems of movement and height adjustment.

[0006] The technical solution adopted in the present application is as follows: a multifunctional study table, wherein a connecting plate is fixedly connected to the lower surface of the supporting hollow column, and a plurality of steering shafts are rotatably plugged into one end of the connecting plate opposite to the supporting hollow column, and a connecting vertical plate is fixedly connected to the side surface of one end of the steering shaft opposite to the connecting plate, and a concave clamping plate is fixedly connected to the side surface of one end of the connecting vertical plate opposite to the steering shaft, and a roller rotating shaft is rotatably plugged into the side surface of the concave clamping plate, and a roller is rotatably plugged into the side surface of the roller rotating shaft, and an anti-slip nut is fixedly plugged into the side surface of one end of the roller rotating shaft opposite to the roller.

[0007] By adopting the above technical solution, the operator uses the supporting hollow column as the supporting structure of the desktop, and uses the connecting plate to carry the moving parts at the bottom. The vertical plate and the concave clamping plate are connected by a steering shaft, and the rollers are connected in series in combination with the roller rotating shaft and the anti-slip nut, so as to realize the movement of the entire device. Among them, the supporting hollow column, as the main structure for bearing force, also plays a connecting role. The connecting plate, as a component in contact with the bottom wheel, has more than one wheel on its side surface, thereby indirectly forming a structure similar to a track, which can make the movement more stable.

[0008] Because of its rotatable nature, the steering shaft not only has the function of connecting the wheels, but also provides the ability to rotate in different directions for movement. The connecting vertical plates and concave clamps serve as the load-bearing components of the wheels, and the wheels are placed in them using their geometric shapes. The connections between the rollers and the roller shafts are all rotatable, providing structural support for the rolling of the wheels. The anti-slip nuts are components that are plugged into both ends of the roller shafts, and are mainly used to prevent the roller shafts from falling off during the rotation of the wheels. With the above structure, the operator can use it to drag the entire study table in any direction, and it can maintain smooth operation during the movement, without the risk of causing things on the desktop to tip over.

[0009] In a preferred embodiment, a plurality of bearing upright plates are fixedly connected to the side surface of one end of the supporting hollow column that is connected to the flat plate opposite to the supporting hollow column, and a plurality of sliding transverse grooves are formed on the side surface of the bearing upright plates.

[0010] By adopting the above technical solution, the bearing vertical plate is used as a structure for bearing the pin rod, mainly providing space for placing the pin rod. The sliding transverse groove is provided to provide a certain movement space for the operator when performing extraction.

[0012] By adopting the above technical solution, the sliding cross bar acts as the main movement structure for pulling out, driving the movement of the pin rod. The pin rod, as the main pulling-out structure in the latch structure, mainly plays a fixing role. The anti-drop sleeve prevents the sliding cross bar from sliding off during the lateral movement. The plug-in hole mainly provides a plug-in space passage for the pin rod.

[0013] In a preferred embodiment, a lifting rod is slidably inserted into the upper surface of the supporting hollow column, and a plurality of height fixing holes are formed on the side surface of the lifting rod.

[0015] In a preferred embodiment, a supporting cross bar is fixedly connected to the side surface of the lifting rod, and a table top is fixedly connected to the side surface of one end of the supporting cross bar facing away from the lifting rod.

[0016] By adopting the above technical solution, the supporting crossbar is used to connect with the desktop, which plays a connecting role and also indirectly realizes a supporting role for supporting the desktop. The desktop, as the desktop of the study table, provides an operating platform for the operator.

[0017] In a preferred embodiment, a bracket rotating shaft is rotatably inserted into the side surface of the connecting plate, an angle fixing bolt is arranged on the side surface of the bracket rotating shaft, and a rotating handle is fixedly connected to the side surface of one end of the bracket rotating shaft opposite to the connecting plate.

[0018] By adopting the above technical solution, the bracket rotation axis is used to connect the fixed bracket and provide a certain degree of flipping performance for the fixed bracket, which is used to switch between the two states of use and non-use. The turning handle is used to provide a force point for the operator to flip the bracket directly by hand. The angle fixing bolt is mainly used to fix the angle of the support frame after flipping to avoid shaking and affecting the effect of position fixation.

[0019] In a preferred embodiment, a support frame is fixedly connected to the side surface of the support rotation axis, and a ground contacting support pad is fixedly connected to the side surface of one end of the support frame opposite to the support rotation axis.

[0020] By adopting the above technical solution, the support frame is used as the force-transmitting structure of the support and the ground contact support pad is used as the structure directly contacting the ground. By means of the above structure, when moving to a certain position, the position can be fixed without sliding.

[0021] In a preferred embodiment, a plurality of anti-rolling grooves are provided on the upper surface of the table top.

[0022] By adopting the above technical solution as an anti-rolling structure, small parts such as pens on the desktop can be prevented from rolling to the ground.

[0023] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0024] In the present application, the operator utilizes the supporting hollow column as the supporting structure of the desktop, and utilizes the connecting plate to carry the moving parts at the bottom.

[0025] The steering shaft is used to connect the vertical plate, the concave clamping plate, and the rollers are connected in series in combination with the roller rotating shaft and the anti-drop nut, so as to realize the movement of the entire device.

There are more than one wheel on its side surface, which indirectly forms a structure similar to a crawler track, which can make the movement more stable.

[0026] The steering shaft, because of its rotatable nature, not only serves as a link to the wheels, but also provides the ability to rotate in different directions for movement. The connecting vertical plate and the concave clamping plate serve as the bearing components of the wheels, and the wheels are placed in them by using their geometric shapes. The plug-in between the roller and the roller shaft can rotate, providing structural support for the rolling of the wheels.

[0027] The anti-drop nut is a component inserted at both ends of the roller shaft, and is mainly used to prevent the roller shaft from falling off during the rotation of the wheel. Through the above structure, the operator can use it to drag the entire study table in any direction, and it can maintain stable operation during the movement without the risk of tipping over the items on the table.
