Description
Technical field
The utility model relates to a kind of multi-functional explosion-proof pressure liftable swivel chair.
Background technology
At present, air-pressure type height-adjusting swivel chair is extensively used as office chair, computer chair etc.By be filled with high pressure nitrogen in the air pressure rod that plays lift action, utilize the pressure differential of gas to reach lifting effect.But the material of using due to some evil mind producers at present do not pass a test, lifting easily causes spark repeatedly, or gas leakage gas purity is inadequate, approaches high temperature heat source etc. and all can set off an explosion, existing many cases have caused grievous injury.
Secondly, in the time of having a rest at ordinary times, especially working clan's lunch break sleep, is all facing upward head rest on arm-chair or lying prone on desk, and after waking up, especially shank blood back is not smooth, numb for a long time.Can cause for a long time the diseases such as varication, be difficult for healthy.For example: the pneumatic lift swivel chair patent No.: 88208737.1.
Utility model content
The purpose of this utility model is: in order to solve the problem of above-mentioned prior art, provide a kind of multi-functional explosion-proof pressure liftable swivel chair.
For achieving the above object, the technical solution adopted in the utility model is: a safety valve is installed on the lower end of air pressure rod, and inner gases at high pressure are communicated with safety valve entrance; The double-deck telescopic movable plate that mounting casing is steel material under seat, there is the firstth slideway groove 17 ground floor portable plate outside, ground floor portable plate inside is equipped with the firstth slideway 16, second layer portable plate outside is equipped with the second slideway groove 21 and is screwed to connect with the second slideway 18, the second slideway 18 slideway leading portions of steel plate inside and is equipped with the antiskid groove lattice 20 with several holes; , inside is equipped with the rectangular strip in end bosses, when portable plate stretches out, and inner rectangular bar-shaped triangularity.
The beneficial effects of the utility model are: mounting safety valve can solve lifting air pressure chair in misoperation or have the danger that has blast in other external cause situations, and install steel plate protection additional, a kind of convenience of simple bed is provided during simultaneously for interim rests such as people's lunch breaks.

Accompanying drawing mark: it is suitable for reading that 1-gases at high pressure are communicated with; 2-high pressure nitrogen; The end opening that 3-gases at high pressure are communicated with; 4-is communicated with safety valve access road; 5-chair; 6-steel material portable plate, 7-adjusting rod; 8-shut off valve; 9-piston; 10-safety valve nut; 11-spring; 12-valve seat; 13-air pressure rod bearing spider; 14-seat roller; 15-steel-made moving plate shell; 16-the first slideway; 17-the first slideway groove; 18-the second slideway; 19-rectangular strip; 20-antiskid groove lattice; 21-the second slideway groove.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is elaborated.
As shown in Figure 1 and Figure 2, a safety valve is installed on the lower end of air pressure rod, inner gases at high pressure are communicated with safety valve entrance; The double-deck telescopic movable plate that mounting casing is steel material under seat, there is the firstth slideway groove 17 ground floor portable plate outside, ground floor portable plate inside is equipped with the firstth slideway 16, second layer portable plate outside is equipped with the second slideway groove 21 and is screwed to connect with the second slideway 18, the second slideway 18 slideway leading portions of steel plate inside and is equipped with the antiskid groove lattice 20 with several holes; , inside is equipped with the rectangular strip in end bosses, when portable plate stretches out, and inner rectangular bar-shaped triangularity.
Specification: in Fig. 1, by adjusting rod lifts or puts down opening or cutting out of gauge tap bolt, if shut off valve is opened, the upper and lower opening that high pressure nitrogen is communicated with by gases at high pressure is realized pressure and is equated, but left and right is different at the upper and lower two ends of piston area, promotion cylinder rises, and makes chair increase, otherwise in like manner.High pressure nitrogen communicates with safety valve by suitable for reading.On safety valve, set safe pressure limiting value by the pretightning force of regulating nut and the elastic force of spring, high pressure nitrogen pressure (equating with cylinder rod internal pressure) below safety valve is if be greater than pressure limit value with amassing of active area, be that safety valve lower reaction power is greater than top, promoting valve seat lifts, discharge gas, pressure is less than nut pretightning force and spring force sum, and valve seat H falls after rise, has avoided causing because air pressure rod internal pressure is excessive the situation of blast.
Fig. 2 is the structure diagram of Fig. 1 steel material portable plate.Movable telescopic plate shell is steel material, even if this is also the one protection to people on chair while there is blast situation.At the inner slideway of installing in the both sides of shell, fix (for indicating) on the way with nut, slideway leading portion is equipped with the active rectangle bar of band eye, and there is the groove adapting to slideway the outside of ground floor expansion plate, fixes with nut, and slideway is also installed in its inside simultaneously.Ground floor portable plate is also hollow, includes the solid portable plate of the second layer.Second layer portable plate outside is equipped with the groove adapting with slideway, fixes with nut, and top is the groove lattice with anti-skidding design, if while facilitating people's rest, can produce larger frictional force with footwear, prevents unstable problem.Two layers of portable plate inside are equipped with the rectangular strip in end bosses, and the projection of the different length rectangular strip stretching out according to portable plate can fasten the hole of diverse location, form triangle, and portable plate is played to reinforcement effect.In the time of people's rest, because portable plate can stretch out two-layerly, have individual gradient relation, the weight that foot takes is larger than shank, therefore second layer portable plate is arranged to solid.
Above content is the further description of the utility model being done in conjunction with optimal technical scheme, can not assert that the concrete enforcement of utility model only limits to these explanations.Concerning the utility model person of an ordinary skill in the technical field, not departing under the prerequisite of design of the present utility model, can also make simple deduction and replacement, all should be considered as protection domain of the present utility model.
