Abstract

The utility model discloses a novel foldable lecture table, which comprises an upper table top, a folding mechanism, a lower table top, a support mechanism and wheels. The two sides of the upper table top are provided with limiting slots which can rotate around the shaft. The shaft is connected with a folding mechanism, the lower end of the folding mechanism is hinged on the lower table top, and the lower table top is fixed on the support mechanism, and the bottom of the support mechanism is provided with four movable wheels, which can make the desk move freely, and the wheel side wall is provided with wheels The braking device and the wheel braking device can control the free movement of the entire table body, which has the advantage of improving the flexibility and mobility of the desk, making it easier to adjust the height and inclination angle of the desktop, and more humanized design.

Description

A New Type of Folding Lecture Table

technical field

The utility model relates to a lectern, in particular to a folding and limiting mechanism of the lectern.

Background technique

Lecture desks play an important role in modern classrooms and provide a lot of convenience for teachers to attend classes. However, the existing desks generally have relatively single functions, difficult height adjustment, and poor mobility.

Contents of the invention

In order to overcome the deficiencies of the above-mentioned technologies, the utility model provides a novel folding desk.

The technical scheme adopted by the utility model is: a new type of folding desk, including an upper table top, a folding mechanism, a lower table top, a bracket mechanism, and wheels, and the two sides of the upper table top are provided with limiting grooves that can rotate around the axis A folding mechanism is pivotally connected to the limiting groove, the lower end of the folding mechanism is hinged on the lower table, the lower table is fixed on the support mechanism, and the bottom of the support mechanism is provided with four movable Wheel, described wheel side wall is provided with wheel braking device, and wheel braking device can control the free movement of whole table body.

The upper end of the folding mechanism is axially connected to the upper table through the limiting groove, and the upper table can freely rotate around the axis in the limiting groove and is fixed by a fixing device. At this time, the lower end of the folding mechanism is hinged on the lower table. It plays the role of supporting the upper table. On the one hand, it can also adjust its folding degree under manual braking to change the height of the entire table body. The wheels set at the bottom of the bracket mechanism can make the table body move freely, and the wheels set on the side wall The braking device is fixed.

Compared with the existing technology, the beneficial effect of the utility model is that on the basis of the original lecture table, a rotatable limiting groove is added on the upper table, so that the upper table can freely rotate around the axis and adjust different angles. The folding mechanism is innovatively adopted, which can easily adjust the height of the table body to meet different height requirements, and the wheels set at the bottom can greatly improve the mobility and flexibility of the lecture table.

specific implementation plan

A new type of folding lecture table, comprising an upper table top 1, a folding mechanism 2, a lower table top 3, a bracket mechanism 5, and wheels 6. The upper table top 1 is provided with limiting grooves 7 that can rotate around the axis on both sides. A folding mechanism 2 is connected to the axis of the groove 7, and the lower end of the folding mechanism 2 is hinged on the lower table top 3, and the lower table top 3 is fixed on the bracket mechanism 5, and four movable wheels 6 are arranged on the bottom of the bracket mechanism 5, and the sides of the wheels 6 The wall is provided with a wheel braking device 10, and the wheel braking device 10 can control the free movement of the entire table body.

The upper end of the folding mechanism 2 is axially connected to the upper desktop 1 through the limiting groove 7, and the upper desktop 1 can freely rotate around the axis in the limiting groove 7 and is fixed by a threaded fixing device 8. At this time, the folding mechanism 2 The lower end is hinged on the lower table top 3. On the one hand, it plays the role of supporting the upper table top 1. On the other hand, it can also adjust its folding degree under manual braking to change the height of the entire table body. The wheels 6 provided at the bottom of the support mechanism 5 can Make the table body move freely, and be fixed by the wheel braking device 10 that side wall is provided with.
