The specific embodiment
Below in conjunction with accompanying drawing 1, to Fig. 8, and the specific embodiment is described further the present invention.
Embodiment: referring to Fig. 1 to Fig. 8.
A kind of safe chair, comprises a seat portion 1 sitting for people, and the below of described seat portion 1 is provided with 4 telescopic legs 2, and leg 2 overcoats have pin spring 3, and the upper end of pin spring 3 is connected with the upper end of leg 2, and the lower end of pin spring 3 is connected with the lower end of leg 2; The below of described seat portion 1 is provided with connecting axle 4, the left and right sides of connecting axle 4 is respectively equipped with folded protection face, described protection face comprises multiple back shafts 5 that distribute from outside to inside, one end of back shaft 5 is provided with hinge hole 51, hinged by hinge hole 51 and connecting axle 4, between the other end of adjacent two back shafts 5 of described protection face, be connected with arc spring 7, on the protection face of two of left and right, between corresponding back shaft 5, be provided with linking springs 6; Described protection face is provided with the switching device closing up for controlling protection face; In the time that protection face closes up, arc spring 7 compresses, and the other end of back shaft 5 is all positioned at rear side; In the time that protection face is opened, arc spring 7 resets; Protection face semicircular in shape or circle.
The present invention is specially adapted to dangerous operation area, in the time causing danger, do not have the too many time to escape, can apply safety chair, and the temporary transient life of keeping waits for rescue.When use, safe chair is placed in personnel rear; Once there is crisis, accomplish at once on safe chair, and open switch.Protection face is opened and is formed a safe space.In the time occurring from the impact of below, leg 2 possesses elasticity, can accomplish better buffering.In the time of impact from upper, forward and backward side, all available spring cushions, thereby forms a safe space.Seat portion 1 includes 4 railings, and railing middle part can arrange seat board or connecting band (not shown in FIG.).In the time that protection face is opened, interior and back shaft 5 outermost forms straight line, and this straight line keeps substantially parallel with the sitting face of seat portion.For guaranteeing the formation of protection face, back shaft 5 interior or outermost is fixedly connected with connecting axle 4.
Further, the below of described leg 2 is provided with bearing plate, and bearing plate is connected with the lower end of 4 legs 2.
Bearing plate is set, the dynamics of bearing of leg 2 is reduced; Also prevent that other rammers from directly clashing into seat portion 1 simultaneously.Secondly bearing plate can also be used for storing food, in case of need.
Further, the other end of described back shaft 5 is provided with installing hole, in the middle of the respective support axle 5 of two protection faces in left and right, is connected with expansion link, and installing hole is fixed in the end of expansion link, and described linking springs 6 is placed on outside expansion link.
Due to general design wider of width of chair, while adopting linking springs 6 that the back shaft of both sides 5 is connected, the easy bending of linking springs 6 causes and connects inconvenience, and this linking springs 6 models are larger simultaneously, cause cost higher.Adopt after expansion link, on expansion link, can be socketed several linking springs 6, thereby reduce the model of linking springs 6, secondly without making linking springs 6 to the strong effect of back shaft 5.Linking springs 6 on expansion link can maintain the original state, and uses more flexible.The structure that expansion link can adopt the sleeve of multiple different inner diameters to be socketed successively, as television antenna,
Further, the other end of described back shaft 5 is also provided with connecting hole, and the end of arc spring 7 is connected with the connecting hole of corresponding back shaft 5 respectively.
Further, between described protection face, be provided with can deformation protective layer 8, linking springs 6 is placed in protective layer 8.
Protective layer 8 can be the bed of cloths such as canvas; Protective layer 8 can be also plastic layer; Protective layer 8 is double-deck.When protection face is opened, arcwall face is sealing state; Also can shrink simultaneously.
Again further, described protection face also comprises protective layer 8, and back shaft 5 is placed in this protective layer 8.
Further, the middle part of two the pin springs 3 in described left side is connected with left contiguous block, and the middle part of two the pin springs 3 in right side is connected with right contiguous block, and left contiguous block and right contiguous block be arranged in parallel, and left contiguous block and right contiguous block are respectively equipped with coaxial axis hole, described connecting axle 4 is connected with axis hole.
Further, described switching device comprises handrail 9, and handrail 9 can be fixed on seat portion, and described handrail 9 is provided with expansion link 91 and is connected with seat portion 1 by expansion link 91, and handrail 9 relatively seat portion 1 moves up and down; The rear end of the hinge hole 51 of described back shaft 5 is provided with hole clipping 52, described connecting axle 4 is provided with accommodation space for its inside of hollow structure, the side of described connecting axle 4 is provided with the chute 42 communicating with hole clipping 52, described connecting axle 4 is provided with through hole 41, described handrail 9 is connected with control lever 10, accommodation space is inserted through through hole 41 in the lower end of control lever 10, described accommodation space is provided with pushing block 11 and fixture block 12, pushing block 11 is between control lever 10 and fixture block 12, the lower end butt of pushing block 11 and control lever 10, in the time that control lever 10 presses down, pushing block 11 moves to fixture block 12 directions; Fixture block 12 is provided with the projection matching with hole clipping 52, and projection is stretched out chute 42 and snapped in hole clipping 52.
In use, its protection face is in closing up state for safe chair, and therefore arc spring 7 is in compressive state, need to there is device by fixing back shaft 5, the technical program adopts fixture block 12 is set on connecting axle 4, by the projection of fixture block 12, back shaft 5 is fixed, and prevents its rotation; Secondly, be provided with movable hand rail 9, take after seat portion 1 at human body, to pressing down handrail 9, handrail 9 presses down control lever 10, and promotes pushing block 11 and fixture block 12 moves, and makes the projection of fixture block 12 leave hole clipping 52, and then opens protection face, simple and quick.
Further, the lower end of described control lever 10 is provided with the first inclined-plane for promoting pushing block 11.
As preferably, described pushing block 11 is provided with the second inclined-plane matching with the first inclined-plane; The first inclined-plane and the second inclined-plane butt.
Inclined-plane is set, can be so that control lever 10 promotes pushing block 11.Control lever 10 is by the first inclined-plane and pushing block 11 butts.
Further, the outer end of described connecting axle 4 is provided with fixture 14 and control spring 13, and control spring 13 is between fixture block 12 and fixture 14.
For the ease of shrinking protection face, the back shaft 5 of every side from the inside to the outside its length increases gradually.
Further, every side of described safe chair is provided with 2 poles and is respectively front support rod 16 and back stay 15, and the lower end of each pole is connected with the lower end of corresponding leg respectively; Stretch out through the rear end of seat portion homonymy the upper end of front support rod 16, and stretch out through the rear end of seat portion homonymy the upper end of back stay 15, in the time that protection face is opened, the upper end of the upper end of front support rod 16 and back stay 15 all with protective layer butt.
Design front support rod 16 and back stay 15, can assist the stressed of carrying protection face; And in the time that protection face is subject to weight ballast, front support rod 16, back stay 15 are all lever state, can bear larger pressure.
Below be only the application's preferred embodiment, equivalent technical solutions on this basis still falls into application protection domain.
