Abstract
The invention discloses an anti-earthquake rescue desk for a pupil or middle school student, and aims to provide the anti-earthquake rescue desk which can effectively bear and withstand impact and disperse pressure, is simple and convenient in operation, simple in structure, low in cost and easy to promote and use widely. The anti-earthquake rescue desk is mainly used in a classroom of a primary or middle school or in a large public place, so that a student can hide below a near anti-earthquake which provides a triangular space for temporary rescue and blindage after deformation once an accident happens and the student cannot escape. Compared with the common desk for student, the asymmetric triangular supporting frame of the anti-earthquake rescue desk can greatly improve the bearing capacity of the desk by dispersing a pressure and provides enough space for the student to hide in. Meanwhile, a desk and chair integrating technique is adopted, so more space is saved. A book holder is designed by using the raised part before the desk for reading and learning. The anti-earthquake rescue desk is convenient and quick in manufacturing, operation and use and is low in cost.
Description
Affiliated technical field
The present invention relates to the desk of a kind of resistance to compression, antidetonation and hedging effect, especially the vibrationproof risk-avoiding desk that can often join at the middle and primary schools classroom.
Background technology
Earthquake is very large to the mankind's injury, but incorrect shock-absorbing mode also is one of reason that causes casualties.In violent earthquake, a lot of students cause seriously injured under desk owing to hiding, even dead.
Many for this reason experts think: shock-absorbing should be selected (side) under indoor solid, the object that can screen health, be easy to form the place of triangular space, the place that the standard width of a room in an old-style house is little, have support.But place that the crowd is dense such as classroom are difficult to find the blindage of taking refuge that more satisfies this requirement.
We know maximum in the common classroom is desk, and desk mostly is wooden or make for other very thin materials, and intensity is not high, and weight capacity is poor, and resistance to pressure, impact resistance are poor, and damage easily.Desktop is fixedlyed connected with table leg, can not move, and desktop is parallel with ground, and the load that can bear is limited.In the process of earthquake, can not effectively resist weight and fall the injury that the student is caused, promptly not have as the take refuge function of blindage of resistance to compression, antidetonation temporarily.
At present, the desk kind with antidetonation, hedging effect that relates in the patent is few, and the main problem that exists is:
1. diverse in function, as increase some earthquake alarming devices, so complex structure;
2. antihunt action mainly plays a supportive role by sturdy table leg, makes that the size of desk is bigger;
3. desk is designed and produced into the square frame case structure, the stress surface of desktop is parallel to ground, and situation about dropping for the weight that takes place in earthquake does not have advantage from the mechanics angle.
Summary of the invention
Goal of the invention of the present invention provides and a kind ofly can effectively carry, withstands shocks, and effectively dispersive pressure, and it is simple to operation, convenient, cost simple in structure is low, the vibrationproof risk-avoiding desk that is easy to promote the popularization use mainly is to use at the middle and primary schools classroom, also can be used for large-scale public place, as library, meeting room, auditorium etc., in case of emergency, when people can not in time be out of danger, this desk can be used as the blindage of interim hedging.
Technical scheme of the present invention:
The technical scheme of accompanying drawings this patent, this vibrationproof risk-avoiding desk mainly comprise desktop 1, asymmetric triangle support frame 3, the rotating shaft strut 5 that reaches connection desktop and bracing frame 3, bilateral six bar linkages 2 etc.Design is succinct practical, can play resistance to compression, the effect of hedging.
The design of asymmetric triangle support frame 3 is mainly considered, effectively dispersive pressure of triangular structure, play the effect of vibrationproof risk-avoiding, the asymmetry design is in order to guarantee the space comfortableness of front and rear row stools for students under the normal condition on the one hand, on the other hand, the student can enter from the side during hedging, and enough living spaces are arranged.
Use 1 guiding function of 2 pairs of desktops of bilateral six bar linkages, realize closing and opening of desktop.Desktop is installed on the bar 3 2.3 of bilateral six bar linkages, asymmetric triangle support frame 3 is installed on the bar 1 of bilateral six bar linkages, make desktop as driving link, under the guiding of bilateral six bar linkages 2, guarantee that under normal circumstances desktop can keep the student to write the height of needs, fit on the triangle support frame and in case of emergency work as desktop, enough Area of bearing can be provided.The rotating shaft strut is in order under normal circumstances to provide certain stability to desktop when the student bends over the desk to write.
Table leg connects with steel plate before two, and a stool that can rebound automatically 4 is installed, and makes the tables and chairs one, can save the space.The partial design that desktop exceeds is a bookshelf, convenient study reading.And below the table leg of back, designed foot rest, improved whole comfort level.
Advantage of the present invention is:
Compare with the pass student desk, asymmetric triangle support frame can make the bearing capacity of desk be greatly improved by the mode of dispersive pressure, triangle support frame provides enough spaces to supply student's hedging, in case various fortuitous events take place, it is beneath in order to avoid cause casualties to enter the antidetonation desk in the time of can't escaping danger nearby.Adopt the technology of tables and chairs one, can save more space.Utilized the partial design that exceeds before a table bookshelf, convenient reading study.Manufacturing, operation, easy to use, simple and direct, cost is low.

The specific embodiment
Under the normal condition, desktop 1 horizontal positioned is supported by rotating shaft strut 5 and bilateral six bar linkages, and height of table top remains on student's desired height when normally bending over the desk to learn.At this moment, the student is sitting on the stool of a back desk.The bookshelf 7 in desktop 1 the place ahead makes things convenient for the student to read a book, and asymmetric triangle support frame 3 back are equipped with pedal 6, have improved comfort level.Because of 3 of desktop 1 and asymmetric triangle support frames are connected by bilateral six bar linkages 2, so can move by planned course.Come rotating shaft strut 5 to be turned to the inboard at dangerous situation temporarily, make it and support lever 9 on same plane, then desktop 1 is closed, the people stands up, and stool closes automatically, hides into getting final product from the side of asymmetric triangle support frame 3 then.About 10 seconds of whole process holding time has guaranteed the sufficient reaction time of student.
