Abstract

The invention discloses a multifunctional quake-proof lifesaving table-chair, which comprises a table (1) and a chair (2), wherein reinforcing ribs (8) are arranged crosswise between two adjacent table legs (3); each table leg (3) is provided with an air filtering device (9); an air filtering device (5) is connected with a breathing nozzle (10); a buffer spring (11) is arranged between each table leg (3) and a table top (5); the bottom end of a backrest (5) is hinged on a chair surface (6); a storage box (12) is arranged below the chair surface (6); an opening (13) of the storage box (12) faces the table (1); the uppermost end of each chair leg (7) is higher than the chair surface (6); the difference between the horizontal height of each chair leg (7) and the horizontal height of the table top (4) is H; and H is smaller than the length of the buffer spring (11). The invention has the advantages that: the table-chair has an artful structure, a reasonable design, high impact resistance and high bearing capability, can help a trapped person treat a wound and prolong life in a severe environment, and the like.

Description

Multi-functional antidetonation lifesaving tables and chairs

Technical field

The present invention relates to a kind of combined type tables and chairs, especially a kind of multi-functional antidetonation lifesaving tables and chairs of in seismic process, protecting personal security, can making the of short duration existence of personnel.

Background technology

Earthquake is a kind of common geological disaster, the generation of earthquake, what often follow is that building collapse, personnel are stranded, the object that has many personnel to be dropped in the process of building collapse is buried, and in the process that object drops, many people can be subjected to great injury, when student especially just at school runs into this situation, because the area in classroom is generally bigger, it is less to help the position that the student hides, and therefore often creates greater casualties.The method of saving oneself that the student generally takes is to hide in the space below desk, but because existing desk generally adopts wooden structures, shock resistance, bearing capacity a little less than, and in case stranded, do not have to help the trapped person to continue life yet, handle the stock items of wound.Therefore need a kind of chair and desk for pupils that can address the above problem to occur now.

Summary of the invention

The present invention is in order to solve the above-mentioned deficiency of existing in prior technology, and it is ingenious to propose a kind of structure, and reasonable in design, impact resistance, bearing capacity are strong, and can help the trapped person to handle the multi-functional antidetonation lifesaving tables and chairs of wound and continuity life under adverse circumstances.

Concrete solution of the present invention is: a kind of multi-functional antidetonation lifesaving tables and chairs, comprise desk 1 and chair 2, desk 1 is made up of table leg 3, desktop 4, chair 2 is made up of backrest 5, seat 6 and chair leg 7, it is characterized in that: arranged in a crossed manner between described two adjacent table legs 3 have a reinforcement 8, also is provided with air filter 9 on table leg 3, is connected with air filter 5 and breathes mouth 10, between table leg 3 and desktop 5, be provided with buffer spring 11

The bottom of backrest 5 is hinged on the seat 6, and the below of seat 6 is provided with hutch 12, and the opening 13 of hutch 12 is towards desk 1 direction, and the top of chair leg 7 is higher than seat 6, and with the difference in level of desktop 4 be H, and H is less than the length of buffer spring 11.

The present invention compares with prior art, has following advantage:

The tables and chairs of this kind of version, rational in infrastructure, design ingenious, the various situations that can take place when it has taken into full account earthquake, and make structural improvement targetedly according to these situations, make it to have possessed and alleviate eminence junk impulsive force in the seismic process, the function of continuity captive life after the earthquake, it can improve the chances of survival of trapped personnel effectively, is particularly suitable for being provided with using for the student in school.

Description of drawings

Fig. 1 is the structural representation of embodiment of the invention state one.

Fig. 2 is the structural representation of embodiment of the invention state two.

The specific embodiment

Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1 and Figure 2: a kind of multi-functional antidetonation lifesaving tables and chairs, comprise desk 1 and chair 2, desk 1 is made up of the desktop 4 of table leg 3 and its upper support, and chair 2 then is made up of backrest 5, seat 6 and chair leg 7; Arranged in a crossed manner between per two adjacent table legs 3 have a reinforcement 8, and it can improve the bearing capacity of table leg 3 effectively; Also be provided with air filter 9 on table leg 3, and also be communicated with breathing mouth 10 with air filter 5, be provided with buffer spring 11 between table leg 3 and desktop 5, it can alleviate the impulsive force that desktop 5 is born effectively;

The bottom of the backrest 5 of chair 2 is hinged on the seat 3, is provided with hutch 12 below seat 6, can prevent in it that ship biscuit, mineral water, adhesive bandage, whistle, little spades etc. from helping the article of trapped personnel existence; The opening 13 of hutch 12 is towards the direction of desk 1, and the top of chair leg 7 is higher than seat 6, and and desktop 4 between difference in level be H, and H is less than the length of buffer spring 11.

In order to strengthen the bulk strength of this device, described desk 1 of present embodiment and chair 2 all adopt metal material to make, and desk 1 is on the ground fixedly connected.

When earthquake takes place, personnel hide in the space below desktop 4, chair 2 is pulled to desk 1, table leg 3 and chair leg 7 are closed up, contact, make the upper end of backrest 5 lean against the edge of desktop 4 then, backrest 5 just constitutes a stable triangular structure with table leg 3 or chair leg 7 like this, when object drops on desktop 4, buffer spring 11 can absorb impulsive force, buffer spring 11 compressions simultaneously, desktop 4 moves downward, the last end in contact of the lower edge of desktop 4 and chair leg 7, table leg 3 like this, chair leg 7, backrest 5 reinforcements 8 together support play desktop 4, and certain space is left in assurance desktop 4 belows;

When earthquake takes place, often have a large amount of dusts, smog, therefore the initial stage trapped personnel that takes place in earthquake can be breathed by breathing mouth 10, utilizes air filter 5 to provide clean air for personnel;

After the earthquake, personnel can carry out simple process to wound by the various medicines that are placed in the hutch 12, and continuity life, wait for rescue worker's rescue.
