Abstract
The utility model discloses combined anti-seismic desk and chair designed specially for students and people with disabilities, which comprise a triangular frame, a connecting rod assembly and a spring structure. When an earthquake does not occur, the anti-seismic desk and chair keep basic structure so as to meet the daily requirements. When certain vibration occurs, the whole anti-seismic chair is inclined forwards, and a chair surface is inclined at a certain angle so as to push a person sitting on the chair below the desk; the whole anti-seismic desk and chair are changed into triangular frame structure by the combination movement of a connecting rod and a spring so as to keep the structure firm; and in the process that a chair bracket is inclined forwards, a sliding block switch of a sliding groove in a main desktop bracket is turned on, and the compressed spring in the main desktop bracket upsprings to lead a main desktop to be changed into the triangular structure, so as to bear the pressure of falling heavy objects in the case of the earthquake, therefore, when the earthquake occurs, the damage of the falling heavy objects to the person is minimized, and the trapped person can be rescued from the front side of the desk only by removing the heavy objects beside the anti-seismic desk and chair in the rescuing process.
Description
Technical field
The utility model relates to a kind of combined type tables and chairs, especially a kind of combined type tables and chairs that the people is protected in earthquake.
Background technology
In, the primary school is the place that the minor relatively concentrates, and the shock resistance of some classroom's building does not reach 8 grades, has hidden danger when earthquake.If can change the desk that present student uses into the resistance to compression desk, when taking place, earthquake plays support, protective effect, reduce the human loss that disaster is brought to a certain extent.The utility model carries out simple conversion at the structure of desk and gets.
Summary of the invention
In order to make the student comprise that physical disabilities are protected timely and succour when earthquake takes place; the utility model provides a kind of combined type antidetonation tables and chairs; to be sitting in personnel on the chair in the moment that earthquake takes place and shift onto below the desk, the people is protected under passive situation timely.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of combined type antidetonation tables and chairs comprise the structure that adopts triangular framing, and the combining structure of connecting rod, spring.When vibrations not taking place, the antidetonation tables and chairs keep basic structure to satisfy needs at ordinary times.When certain vibrations take place when, shockproof chair medi-spring hinge drives whole bar linkage structure motion under the effect of vibrations, whole shockproof chair is turned forward, the moving driven pulley guide rod of rotating band takes place in driven pulley under the drive of Spring hinge, and then drive the chair master connecting-rod and the chair slave connecting rod moves downward, open the node of seat rack rod by the chair slave connecting rod, make the inclination of seat generation certain angle, be sitting in people on the seat with passive below seat is slipped to auxiliary table surface.Meanwhile, the horizontal movement of the armrest of seat that bolt horizontal movement in the chair master connecting-rod drive armrest support connecting rod and then maintenance contain chute, in the chute between armrest of seat level insertion auxiliary table surface support and the auxiliary table surface, make the whole structure that forms a triangular framing, in order to keep integrally-built fixing.Chair support is opened the slider switch of chute in the top table face support in the process that turns forward, compressed spring is upspring and is made the top table face also form a triangular structure in the top table face support, be used for bearing the pressure of the weight that is fallen when earthquake takes place, to reach guarantor's purpose of safety.
The beneficial effects of the utility model are, the people carries out shockproof under passive situation, the injury of weight of collapsing that can maximum possible reduce produces when earthquake takes place to the people, and can behave in hiding in the zone of people necessary survival goods are provided, wish thereby make the people obtain maximum possible existence.When rescue, only need remove the weight on this shockproof tables and chairs next door and can rescue trapped personnel from the front of table.

The specific embodiment
In Fig. 1, table assistant support 4 can obtain the student that different top table face height adapts to different heights when inserting different bolts hole 1, base 2 is in order to fixing total, table main support 3 is supported the main structure of whole table, there is certain height to deposit stationery such as school bag between auxiliary table surface 6 and the top table face 8, can deposit some food and drinking water in case of necessity, auxiliary table surface support 5 and top table face support 7 are in order to support primary and secondary desktop.Shockproof chair will keep as shown in fig. 1 to satisfy needs at ordinary times when not shaking always.
In Fig. 2, when certain vibrations take place when, Spring hinge 16 is under the effect of vibrations, Spring hinge 16 drives Spring hinge master connecting-rod 17 and Spring hinge slave connecting rod 20 moves, driving whole shockproof chair then turns forward, the moving driven pulley guide rod 18 of rotating band takes place in driven pulley 19 under Spring hinge slave connecting rod 20 drives, and then drive chair master connecting-rod 14 and chair slave connecting rod 15 moves downward, chair slave connecting rod 15 is opened the node of seat rack rod 13, make seat 12 that certain inclination take place, be sitting in people on the seat 12 with passive below seat 12 is slipped to auxiliary table surface 6.
In Fig. 3, chair master connecting-rod 14 drives the bolt horizontal movement in the armrest support connecting rod 11 and then makes the maintenance level of the armrest of seat 10 that contains chute, in the chute between armrest of seat 10 levels insertion auxiliary table surface support 5 and the auxiliary table surface 6, make the whole structure that forms a triangular framing, in order to keep integrally-built fixing.Chair support 9 is opened the slider switch of chute in the top table face support 7 in the process that turns forward, the compressed spring in the top table face support 7 is upspring and made the top table face also form a triangular structure, is used for bearing the pressure of the weight that is fallen when earthquake takes place.
