A new type of spiral lifting student desk

technical field

The utility model relates to the technical field of teaching, in particular to a student table.

Background technique

Now the height-adjustable desks used by students are fixed with bolts and nuts, which is very inconvenient to adjust. In addition, students have a lot of learning pressure and a lot of books. The desks they use cannot hold many books, and they are placed very Cluttered and not well laid out. These are all the weak points of currently used desks. At present, someone has designed a lifting desk, but its desktop is fixed with the screw rod, and the screw transmission is realized by rotating the desktop and the purpose of lifting the desktop is achieved. It is easy to rotate like this, but it is not very easy in specific operations. It is suitable, because most of the desktops are square, and a certain amount of space is required for rotation. When the desktop is rotated to a suitable height, the orientation of the desktop may not be suitable, and it may not be facing people.

Utility model content

The purpose of this utility model is to provide a new type of spiral lifting student desk for the shortcomings of the above-mentioned prior art, which solves the technical problems that the existing desks are inconvenient to lift and store few books.

There is a handle between the lower ends.

The different helical directions of the upper end and the lower end of the double-ended screw make the lifting of the table body be realized when the double-ended screw is rotated by the handle.

As a preference, the bottom of the table body is provided with an upper support screw sleeve, the top of the desk bracket is provided with a lower support screw sleeve, the upper end of the double-ended screw is threaded with the upper support screw sleeve, and the lower end is threaded with the lower support screw sleeve, and the double-ended The upper end of the head screw is a right-handed thread, and the lower end is a left-handed thread.

The upper support screw sleeve plays the role of supporting the table body, and the lower support screw sleeve plays the role of supporting the desk bracket.

Preferably, support ribs are provided on both sides of the upper support screw sleeve and the lower support screw sleeve.

The support rib can strengthen the rigidity of the upper support screw sleeve and the lower support screw sleeve, and also has the function of supporting and stabilizing the table body.

Preferably, the upper and lower ends of the double-ended screw are threaded with a threaded cover.

The thread cover has the function of covering the thread section of the double-ended screw, avoiding the thread from being exposed, and ensuring a beautiful appearance; meanwhile, it also plays a role of dust prevention, preventing dust from falling into the thread section of the double-ended screw, causing the thread to be unsmooth and the rotation inflexible.

As a preference, two drawers are provided on the front of the table body, a chute is arranged in the drawer along the drawing-out direction, and a book partition is movably assembled on the chute.

The book partition is used to block the books placed in the drawer so that the books are arranged neatly.

Preferably, the two drawers are a left drawer and a right drawer, and the interior of the left drawer is divided into a front storage cavity and a rear storage cavity, and a book partition is provided in the front storage cavity.

The front cavity of the left drawer is used for placing infrequently used books, and the rear cavity is used for storing rolls and notebooks. The right drawer is for frequently used books.

Preferably, a pen holder is provided on the top surface of the table body.

The pen holder is used to insert the pen, which is convenient to use and can also add to the learning atmosphere.

Preferably, a guard rail is provided on the edge of the top surface of the table body.

The protective fence can prevent the objects on the desktop from falling to the ground.

Compared with the prior art, the utility model has the beneficial effects of solving the problem that the height-adjustable desks used by students are fixed with bolts and nuts, and the height is fixed every time, and the height adjustment is very inconvenient. There are many students' books, and the table used can't fit the problem. The height of the student desk can be adjusted arbitrarily within the designed adjustment range, which can correct the sitting posture of the students and reduce the fatigue of the students. It can accommodate a large number of books, has a good layout, and is easy to use.
