Description
Technical field
The utility model relates to chair lift accessory field, is specifically related to a kind of chair lift cylinder supports device.
Background technology
Pressure liftable chair is the most frequently used chair in office space, has the features such as cheap, structure simple, flexible operation, therefore extensively get consumer reception due to pressure liftable chair.According to estimates, more than 80% office building and company all at use pressure liftable chair.Along with popularizing of PC, pressure liftable chair also starts to be used as computer chair by many families.
A cylinder is had between the seat of existing pressure liftable chair and chassis, filling 1 ~ 2 atmospheric nitrogen in cylinder, and seal with sealing ring, piston rod in cylinder can move up and down under pressure, match with the regulating handle (i.e. locking device) of seat, the elevating function of chair can be realized.Under normal circumstances, this device can not be blasted.If nitrogen gas purity filling in cylinder is inadequate, environment temperature is too high and adjust height up and down continually and piston rod and cylinder wall are constantly rubbed, and may cause gas undergoes rapid expansion thus blast.If use defective material or process for machining and manufacturing existing problems, also may cause pressure liftable device insufficient strength, cause Leakage Gas or explosion caused.
Utility model content
The purpose of this utility model is to provide a kind of chair lift cylinder supports device reducing pressure liftable chair explosion hazard.
The utility model is by the following technical solutions:
A kind of chair lift cylinder supports device, comprises support member and terminal pad; Described support member comprises cylinder stationary pipes and tube connector, be connected bottom the tube wall of the two, the top of described tube connector is fixedly connected with described terminal pad, terminal pad has cylinder and fix pore, the grafting of described cylinder stationary pipes is fixed on this cylinder and fixes in pore, the top of cylinder stationary pipes extends to the tubular axis heart, and form the spacing collar being used for spacing fixing cylinder top, the hole that described spacing collar surrounds is shut off valve guide rod hole.
Described terminal pad is provided with the connecting hole for being fixedly connected with chair lift body.
Described terminal pad comprises two-layer up and down, and upper strata diameter is greater than lower floor's diameter, is fixedly connected with between two-layer by connecting rod; Described connecting hole is arranged on upper strata, and described tube connector is fixedly connected with lower floor, for regulate chair lift height and regulating handle that shut off valve guide rod is hinged by described two-layer up and down between space extend to outside terminal pad.
The upper strata of described terminal pad is discoid.
Described cylinder stationary pipes is connected with rounding off bottom the tube wall of tube connector, rounding off between described cylinder stationary pipes and spacing collar.
Good effect of the present utility model is: cylinder can be fixed in cylinder stationary pipes by the utility model, when cylinder occurs that accident is blasted, the spacing collar at described cylinder stationary pipes top can limit cylinder and upwards go out, and reduces the splashing of fragment, thus reduces the harmfulness of blast.The structure of terminal pad is convenient to be connected and fixed with chair lift body, makes the use of regulating handle convenient.The top-level design of terminal pad becomes solid disk, and cylinder or fragment can be stoped further to the injury of seat user.
