Abstract
The utility model discloses an anti-seismic life-saving desk, comprising a base, a desktop, a desk container connecting bag, desk container guide rails, a desk container board, a desk container push rod, an upper supporting rod and a lower supporting rod, wherein the base is a triangular frame welded by two parallel square pipes, and the triangular frame is internally connected into a whole by welding seven pipe materials with rectangular sections; a round pipe is welded on the base and is internally provided with a compression spring and a shaft core; the base is also provided with a self-locking spring pin and a starting spring pin; the base is connected with a desktop part and a supporting part by a hinge; the upper supporting rod and the lower supporting rod are matched to form a supporting part; and the lower supporting rod is provided with a safety pin and a self-locking spring pin. According to the anti-seismic life-saving desk, the structure is reasonable, the design is ingenious, and the structure of the desk is redesigned by considering the condition that students do not escape towards outdoor in time when the earthquake occurs, so that the capability of bearing large impact load is achieved and the life safety of the students refuging under the anti-seismic life-saving desk can be effectively protected.
Description
Technical field
The utility model relates to a kind of lifesaving desk, and the lifesaving desk that particularly a kind of antidetonation is used is mainly failed in time to escape from the students in middle and primary schools in classroom when protecting earthquake and developed.
Background technology
Earthquake is a kind of common geology natural calamity, and earthquake comes interim often let us to realize the fragility of frightened and life deeply.In the casualties that earthquake causes, often accounted for very big ratio in the number of students in middle and primary schools' injures and deaths.The oriented outdoor race of the escape mode that students in middle and primary schools are traditional and hiding under the desk; For under the less situation of this personnel's places with dense of school and students in middle and primary schools' age outwards race be unallowed in time; It is less qualified to do it below common school desk to hide; Common school desk is timber structure basically, and intensity is low, holds the wall that can't stand collapses gets off or the impact of top board.To this situation, we have invented antidetonation lifesaving desk.
The utility model content
The utility model relates to the antidetonation lifesaving desk that in earthquake, can protect student's health and life to escape injury; The student meets with earthquake in the classroom; Can hide and under desk, take refuge if having little time to run away to the open air, the desk action forms triangle and protects the space, thus protection table student's safety down.
The purpose of the utility model provides a kind of shock resistant desk, though this desk have that floor caves in also not can ruined intensity, thereby guarantee to hide student's health and the life security of under table, taking refuge.
In order to achieve the above object, the utility model comprises the framework that the welding of sufficient size strength metal material is processed, desktop (4) and table pocket part boarding, and protection baffle plate (2) is equipped with in the front portion.
The framework that the utility model adopts Metal Material Welding to form, coupling part are used hinge and are connected.Can catch a pocket push rod (8) or a cross bar of bottom when the student hides in table following time, can keep one's balance.
The utility model is when processing framework with metal material, and desktop (4) is hinged with base (1) and the many places employing of table pocket, rod member interconnects and forms.Certainly, also can adopt engineering plastics replacements metal under the prerequisite of requirement of strength satisfying, or metal is used in combination with engineering plastics.
In addition, the described protection barrier material of the utility model can be metallic plate or nylon sheet, the some through holes on the protection baffle plate (2), and pass can be any geometric figure, and also can be combined into the pattern that designs by these some holes.
The utility model comprises: base (1), desktop (4), table pocket connecting rod (5), table pocket guide rail (6), table pocket plate (7), table pocket push rod (8), upper support bar (9) and lower support bar (13).Base (1) is by the triangular framing of two parallel square tube welding; The centre fuses it through the tubing that welds seven rectangle cross sections; The welding pipe on square tube top; Pack into and compress spring (14) and mandrel (15), and be provided with startup spring catch (18) and self-locking spring pin (17), be used for the startup and the self-locking of jacking mechanism at dress pipe place; Desktop (4) is made up of desktop and desktop framework, tabletop section and base (1) and the support section supporting desktop that is connected through the hinge; Under desktop (4), be connected a table pocket with two table pocket push rods (8) by eight table pocket connecting rods (5), wherein eight table pocket connecting rods (5) are used for a suspension table pocket, and two table pocket push rods (8) promote the motion of table pocket when being used at ordinary times fixing and action; Support section is made up of the upper support bar (9) and the lower support bar (13) of a pair of cooperation, offers self-locking spring pin (11) and safety plug (10) on the lower support bar (13), is used for the startup of system acting and the locking of support section.
The utlity model has following advantage: this antidetonation lifesaving desk is rational in infrastructure; Deft design; The student has designed the desk structure again under the untimely situation of outdoor escape when considering earthquake; Make it to have the ability of the heavy shock loads of bearing, can effectively protect student's life security of under this antidetonation lifesaving desk, taking refuge.
