Embodiment Construction

[0027] Attached below Figure 1-12 The present invention is described in detail below.

[0028] Such as Figure 1-12 As shown: 1. Desktop 2. Double-side six-bar linkage device 3. Asymmetric triangular support frame 4. Stool 5. Rotary shaft support rod 6. Pedal 7. Bookshelf 8. Front baffle 9. Both sides of the support lever Six-bar linkage: 2.1, bar one 2.2, bar two 2.3, bar three 2.4, bar four 2.5, bar five 2.6, bar six.

[0029] In the normal state of the present invention: the desktop 1 is placed horizontally, supported by the rotating shaft strut 5 and the six-bar linkage device on both sides, and the height of the desktop is kept at the required height for students to study at their desks normally. At this point, students sit on stools at the back table. The bookshelf 7 in the front of the desktop 1 is convenient for students to read books, and the asymmetrical triangular support frame 3 is equipped with a pedal 6 in the back, which improves the comfort. Because the de...

Abstract

The invention relates to the technical field of force bearing structures, in particular to a strengthened safe student desk and chair assembly capable of resisting earthquake and avoiding risk. The student desk and chair assembly comprises a desk top, a front baffle, a foot rest, an asymmetric triangular supporting frame, a rotating shaft supporting rod positioned below the desk top, a fixed bookshelf in front of the desk top, a bilateral six-bar linkage device, a stool and a supporting gear rod; the bilateral six-bar linkage device which is designed specially is connected with the desk top and the asymmetric triangular supporting frame, and is an important mechanism allowing the desk top to move along a designed track; the desk top is clung to the asymmetric triangular supporting frame and coplanar with the foot rest, and the desk top, the foot rest and the front baffle constitute two protection surfaces of a triangular space in an earthquake resisting and risk avoiding state. Compared with a common student desk, the strengthened safe student desk and chair assembly has the advantages that the bearing capacity of the desk can be greatly improved by the asymmetric triangular supporting frame in a pressure dispersing manner, and enough space for allowing students to avoid risk is provided by the triangular supporting frame; the bookshelf is designed at the part higher than the front part of the desk, so that good convenience is provided for reading and studying; and the desk and chair assembly is convenient to manufacture, operate and use, simple and low in cost.

Description

technical field [0001] The invention relates to the technical field of force-bearing structures, in particular to a reinforced anti-seismic and safe student desk and chair. Background technique [0002] Earthquakes are very harmful to humans, but incorrect shock absorption methods are also one of the causes of casualties. During the earthquake, many students were seriously injured or even died because they hid under their desks. [0003] For this reason, many experts believe that the shock absorber should choose a place that is strong indoors, under (beside) objects that can cover the body, and a place that is easy to form a triangular space, with a small bay and a place with support. However, it is difficult to find more refuge shelters that meet this requirement in densely populated places such as classrooms. [0004] We know that the most common classrooms are desks, and desks are mostly made of wood or other thin materials, with low strength, poor load-bearing capacity...
