By the enforcement of technique scheme, the utility model has the advantages that: only need a staff just can move volleyball referee chair easily, mobile very convenient, time saving and energy saving, and store again after volleyball referee chair can being folded, substantially reduce the volume of volleyball referee chair, and then the space that need take when substantially reducing storage, improve the availability in space.
Accompanying drawing explanation
Fig. 1 is the structural representation of simple and easy volleyball referee chair described in the utility model.
Fig. 2 is the structural representation of the left apparent direction of Fig. 1.
Fig. 3 is the folded state schematic diagram of the simple and easy volleyball referee chair shown in Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1, Fig. 2, shown in Fig. 3, described simple and easy volleyball referee chair, comprise bracing frame 1 and cat ladder 2, the upside of cat ladder 2 is hinged with the upside of bracing frame 1 by the first rotating shaft 3, the downside of cat ladder 2 is hinged with the hinged end of first connecting rod 5 by the second rotating shaft 4, the drive end of first connecting rod 5 is hinged with the drive end of second connecting rod 7 by the 3rd rotating shaft 6, the hinged end of second connecting rod 7 is hinged with the downside of bracing frame 1 by the 4th rotating shaft 8, overturn platform 9 is provided with between cat ladder 2 and bracing frame 1, one end of overturn platform 9 is hinged with bracing frame 1 by the 5th rotating shaft 10, the other end offers draw-in groove, when first connecting rod 5 stretching mutual to second connecting rod 7, the draw-in groove turn on the overturn platform 9 of level is just in time buckled on the cross bar 11 of the top in cat ladder 2, on front side of the bottom of cat ladder 2, be also provided with roller 12, roller 12 when volleyball referee chair horizontal positioned not with earth surface, roller 12 then supports on the ground when volleyball referee chair turns forward, in the present embodiment, bracing frame 1 above overturn platform 9 is provided with magnet 13, when overturn platform 9 turns over to bracing frame 1, overturn platform 9 is just in time absorbed and fixed on bracing frame 1 by magnet 13, like this after overturn platform 9 and cat ladder 2 are separated, overturn platform 9 can be fixed on bracing frame 1, avoid overturn platform 9 to damage because freely overturning workman, improve safety, in the present embodiment, also upwards handrail 14 is integrally extended with at the top of bracing frame 1, when the person of acting as a referee stand on the overturn platform 9 of the placement that is the level of state like this, can be hand steered handrail 14, prevent referee from falling from overturn platform 9, thus had further guarantee to the personal safety of referee, substantially increase the safety in utilization of volleyball referee chair, and when volleyball referee chair is in folded state, staff can be made to hold up, and handrail 14 promotes to be in the volleyball referee chair of folded state, makes staff can move volleyball referee chair more easily, in the present embodiment, be also arranged with sheath 15 respectively at cat ladder 2 and the external surface of bracing frame 1, effectively can prevent the external surface of cat ladder 2 and bracing frame 1 to get rusty because being exposed to air the generation of phenomenon like this, and then extend the application life of volleyball referee chair, in the present embodiment, footmuff 16 is also arranged with at the external surface at the position that cat ladder 2 and ground touch, the position that cat ladder can be avoided like this to contact with ground (floors as stadiums) is damaged because of excessive friction, extend the application life of volleyball referee chair further, also avoid the floor damaging stadiums simultaneously,
Operating principle of the present utility model is as follows:
During use, by a staff, the volleyball referee chair being in folded state placement is pulled to heeling condition, roller 12 is supported on the ground, handrail is held up volleyball referee chair to be pushed into judge's seat put area on competition area by this staff again, after arriving judge's seat put area, volleyball referee chair is just put by staff again, then to pressing down the 3rd rotating shaft 6, in the process that the 3rd rotating shaft 6 moves down, 3rd rotating shaft 6 promotes cat ladder 2 downside by first connecting rod 5 is outwards opened around the first rotating shaft 3, and the downside being promoted bracing frame 1 by second connecting rod 7 is outwards opened around the first axle 3 simultaneously, thus the downside of the downside of cat ladder 2 and bracing frame 1 is separated from each other, until first connecting rod 5 and second connecting rod 7 mutually stretching time stop the action pressing down the 3rd rotating shaft 6, now, bracing frame 1 and cat ladder 2 just stably support on the ground under the support of first connecting rod 5 and second connecting rod 7, then turn over to level under making overturn platform 9 overcome the suction of magnet 13, make draw-in groove on overturn platform 9 just in time with the cross bar 11 phase buckle of the top of cat ladder 2, such overturn platform 9 just defines with the platform for referee's standing activity, pass through aforesaid operations, namely the use completing referee's chair is installed, when use terminates to store, first one end of the band draw-in groove of overturn platform 9 is upwards lifted, after the cross bar 11 of the top of draw-in groove and cat ladder 2 is separated, continue again overturn platform 9 to turn over to adsorbing fixing with magnet 13 phase, then again the 3rd rotating shaft 6 is upwards lifted, in the process that the 3rd rotating shaft 6 moves up, 3rd rotating shaft 6 promotes cat ladder 2 downside by first connecting rod 5 is inwardly rotated around the first rotating shaft 3, and the downside being promoted bracing frame 1 by second connecting rod 7 is inwardly rotated around the first rotating shaft 3 simultaneously, thus cat ladder 2 and bracing frame 1 are drawn close mutually, until will the 3rd rotating shaft 6 be lifted to initial position, now, namely the folding operation to volleyball referee chair is completed, referee's chair is pulled to heeling condition by the personnel that proceed with one's work, roller 12 is supported on the ground, hold up handrail 13 that referee's chair is pushed into storage area by this staff again.The utility model has the advantages that: only need a staff just can move easily and volleyball referee chair is installed, mobile very convenient, time saving and energy saving, and store again after volleyball referee chair can being folded, substantially reduce the volume of volleyball referee chair, and then the space that need take when substantially reducing storage, improve the availability in space.
