Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of cushion, particularly used in fire-fighting cushion.
Background technology
Cushion on existing fire extinguishing tanker is identical with the cushion on general-utility car, and they are all fixed by the seat of connecting strap and vehicle.When cushion is on fire extinguishing tanker, because the operator's compartment of fire extinguishing tanker and ground exist larger distance, when fire fighter in operator's compartment out time, generally need two steps: 1, first rotate health and health and operator's compartment are exported face; 2, fire fighter by outlet in operator's compartment out.There is a problem in above-mentioned step: cushion is fixed together with the seat of vehicle in implementation process, namely cushion is fixed, simultaneously, in order to increase the traveling comfort of cushion, existing cushion outside face is made by leather, fine hair etc. substantially, and namely cushion outside face exists certain roughness.When fire fighter rotates health, between fire fighter and cushion, larger friction can be produced, add the time consumed when fire fighter gets off dramatically, thus fire is put out impact.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the used in fire-fighting cushion that can shorten the time getting off.
The purpose of this utility model realizes by following technical proposal: used in fire-fighting cushion, it is characterized in that, comprise in discoideus Weight plate, the upper end of described Weight plate is provided with in discoideus connecting panel, and connecting panel and Weight plate coaxial, there is in the middle part of the lower surface of described connecting panel the rotating shaft in cylindric protrusion, and described rotating shaft and described Weight plate axial restraint, the friction mechanism making both produce friction drag is provided with between described Weight plate and connecting panel, the upper surface of described connecting panel is fixed with the housing with closed chamber, described housing is made up of flexible material, sponge is filled with in described chamber, described housing is discoideus under occupied state, and housing under occupied state is coaxial with described connecting panel.
During use, Weight plate is placed on the seat, and under the effect of Weight plate self gravitation, by whole cushion stable position.Fire fighter is sitting on housing, and under the effect being filled in the sponge in chamber, to provide good traveling comfort.When needs are got off, fire fighter only need firmly make connecting panel overcome car door mouth place that friction drag turns to fire extinguishing tanker, can rapidly in fire extinguishing tanker out, effectively shorten the time consumed when fire fighter gets off, thus can put out fire rapidly, reduce the loss that fire causes.Making between Weight plate and connecting panel, to produce comparatively failure-free friction by arranging friction mechanism, effectively avoiding the situation lower connecting plate of not exerting oneself fire fighter to rotate, thus improve the traveling comfort of this cushion.

Spring is all identical with steel ball with the quantity of location division and position is all one to one.Under the action of the spring, steel ball, together with the madial wall tight abutment of annular groove, produces comparatively failure-free friction, is reduced in the probability that situation lower connecting plate that fire fighter do not exert oneself rotates further, thus improves the traveling comfort of this cushion.
In above-mentioned used in fire-fighting cushion, the madial wall of described annular groove is the circular arc matched with described steel ball.
Adopt above-mentioned structure, increase the area of contact of steel ball and connecting panel, effectively increase the reliability producing friction force between connecting panel and steel ball, thus further increase the traveling comfort of this cushion.
In above-mentioned used in fire-fighting cushion, location division is be opened in the positioning groove on Weight plate end face, and described spring is positioned at positioning groove, and the two ends of spring offset with positioning groove diapire and steel ball respectively.
Adopt above-mentioned structure, good positioning action is played to spring, make steel ball have the trend offseted with annular groove madial wall under the action of the spring all the time, to form comparatively failure-free friction, further increase the traveling comfort of this cushion.
Alternatively, in above-mentioned used in fire-fighting cushion, described location division is the sleeved part that Weight plate end face protrudes in column, and spring housing is located in sleeved part, and the two ends of spring offset with Weight plate and steel ball respectively.
Alternatively, in above-mentioned used in fire-fighting cushion, described friction mechanism is the friction disc be set in rotating shaft, and one end of described friction disc is connected mutually with Weight plate, and the other end of friction disc and connecting panel offset.
In above-mentioned used in fire-fighting cushion, described housing comprises rounded connecting strap, and described connecting strap has two panels, and the connecting strap described in two is connected by the bound edge that is looped around connecting strap surrounding, and forming above-mentioned chamber between bound edge and two connecting straps, described bound edge and connecting panel fix.
Form chamber by the mode arranging bound edge parcel connecting strap, effectively ensure that the leak tightness of chamber, enter in chamber to stop water damage is caused to sponge, thus improve the service life of this cushion.
Compared with prior art, this used in fire-fighting cushion has the following advantages:
1, when needs are got off, fire fighter only need firmly make connecting panel overcome car door mouth place that friction drag turns to fire extinguishing tanker, can rapidly in fire extinguishing tanker out, effectively shorten the time consumed when fire fighter gets off, thus can put out fire rapidly, reduce the loss that fire causes.
2, making between Weight plate and connecting panel, to produce comparatively failure-free friction by arranging friction mechanism, effectively avoiding the situation lower connecting plate of not exerting oneself fire fighter to rotate, thus improve the traveling comfort of this cushion.
3, under the action of the spring, steel ball, together with the madial wall tight abutment of annular groove, produces comparatively failure-free friction, is reduced in the probability that situation lower connecting plate that fire fighter do not exert oneself rotates further, thus improves the traveling comfort of this cushion.
4, the mode by arranging bound edge parcel connecting strap forms chamber, effectively ensure that the leak tightness of chamber, enters in chamber and causes damage to sponge, thus improve the service life of this cushion to stop water.
