Description

shockproof desk

technical field

The utility model relates to school supplies, in particular to an anti-shock desk. the

Background technique

Students spend most of their time at school in the classroom. In the face of a devastating earthquake, school buildings and other teaching facilities are the first place to provide students with safe shelter. my country's earthquake areas are widely distributed, and many school buildings fail to meet the earthquake-resistant requirements. At present, in addition to measures such as earthquake-resistant reinforcement and reconstruction, there is another important measure that cannot be ignored, that is, to consider earthquake-proof issues from the perspective of making full use of desks and chairs . The first thing for students to learn about shock resistance in the classroom is to quickly squat under their desks, so using desks and chairs to prevent shocks is an important shock-absorbing measure. Through extensive investigation and relevant data analysis, the current design standards for desks and chairs in my country do not consider the problem of shock resistance. Once a major earthquake occurs, it is difficult for ordinary desks and chairs to have a good shock resistance effect. the

Professor Zhou from Guangzhou, after the Wenchuan earthquake, devoted himself to research and invented an anti-seismic table that can bear more than 100 tons. However, the price of more than 1,000 yuan for the anti-seismic table has become the biggest obstacle for Professor Zhou to carry out marketing. Moreover, the table legs he made are made of steel pipe concrete members with an outer diameter of 140mm, and the weight of one table leg alone reaches 45 kg. Not only is it difficult to make, but the table is also heavy. Can only be placed in a fixed position. Combining the above two anti-shock tables, their problems include: difficult production, strict material requirements, heavy weight, single function, and high cost. the

Further, the above-mentioned shockproof desk also includes a support leg fixed at the center of the bottom surface of the desktop. the

Further, in the anti-shock desk as mentioned above, the table legs are made of seamless steel pipes. the

Further, in the anti-shock desk as mentioned above, the supporting legs are made of seamless steel pipes. the

Further, as for the above-mentioned shockproof desk, the desktop is made of a compression-resistant composite board. the

Further, for the anti-shock desk as mentioned above, the four table legs 12 are fixedly connected together by the iron frame 18 . the

The anti-shock desk provided by the utility model has a simple manufacturing process and is suitable for general mechanical processing plants; the material is widely used in the market; it is light in weight and suitable for random movement. It is not only suitable for use as a desk in school classrooms, but also suitable for Home, hotel, office building and many other places; at the same time, the manufacturing cost of this work is low, suitable for mass production. the

Detailed ways

In order to make the purpose, technical solutions and advantages of the utility model clearer, the technical solutions in the utility model will be clearly and completely described below in conjunction with the accompanying drawings in the utility model. Obviously, the described embodiments are the embodiment of the utility model. Some of the embodiments are novel, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work, all belong to the protection scope of the present invention. the

Fig. 1 is the structure schematic diagram of the utility model anti-shock desk, as shown in Fig. 1, the anti-shock desk provided by the utility model, comprises desktop 11 and the table leg 12 that sets four corners of sub-table top, four table legs 12 adopt crank The rocker mechanism is connected with the desktop 11. The utility model provides an embodiment of a crank and rocker mechanism, specifically: the crank and rocker mechanism includes a first fixing part 13, a second fixing part 16, a first connecting part 14, and a second connecting part 15. One end of the first fixing member 13 is vertically fixed on the bottom surface of the desktop 11, the other end is hingedly connected to one end of the first connecting member 14, the other end of the first connecting member 14 is hingedly connected to one end of the second connecting member 15, and the second The other end of the connecting piece 15 is hingedly connected to one end of the second fixing piece 16 , and the other end of the second fixing piece 16 is vertically fixedly connected to the table leg 12 . the

In the anti-shock desk provided by the utility model, the connection part between the table legs and the table top is connected by a crank rocker mechanism, which can play a good role in buffering pressure, so that the pressure resistance of the table can be fully improved. the

Further, it also includes a support leg 17 fixed at the center of the bottom surface of the desktop 11 . the

The support legs 17 not only increase the compression resistance and stability of the table again, but also provide a safe and easy place for the refugee to fix himself. When the refugee fixes himself, the table can be further strengthened. Stability kills two birds with one stone. It can provide an excellent temporary shelter for asylum seekers before rescue comes. the

Further, in order to further improve the performance of compressive resistance, the table legs 12 and the supporting legs 17 are all made of cost-effective seamless steel pipes. the

Further, the desktop 11 is made of a composite board with better pressure bearing performance, and the four table legs 12 are fixedly connected together through the iron frame 18, and the side of the iron frame 18 facing the students is empty, without the iron frame, This is convenient for students to quickly get under the desk. the

The tabletop 11 adopts compression-resistant composite boards, which can bear enough pressure caused by the collapse of the house after an earthquake occurs, and saves materials and reduces the weight of the table. will be bigger. In this way, when an earthquake occurs, the desktop 11 can not only play the role of anti-buffering, but also increase the contact area with falling objects. Distributes the pressure to the five legs of the table. the
