Description

Go up and down chair

Technical field

The utility model belongs to chair art, more particularly to a kind of lifting chair.

Background technique

There is a cylinder between the seat and chassis of lifting chair, the nitrogen of filling 1-2 atmospheric pressure in cylinder excludes quality Problem if usage mode is improper is also possible to that safety accident occurs.The lifting seat of Most current is all by being mounted on chair The handle of sub- bottom manipulates the lifting of seat, which stretches out outside seat, obvious and conveniently once touching and can encounter, and often has People frequently pulls the handle of chair lift because of joyful or subconscious movement, causes chair lift continually to go up and down repeatedly, gas Cylinder heats up suddenly, can explode at any time.In recent years, lifting chair explosion injury occurrences in human life part often occurs, it is therefore necessary to pay attention to rising Drop chair using safe.

In addition, stretching out the handle outside seat using the gas valve of lever principle manipulation cylinder head, gently once drawing energy Gas valve is opened, the size of the power acted on gas valve is heavily dependent on the big of the power of user's pulling handle Small, this just increases the probability of gas valve damage, if worrying Quick adjustment seat height even can draw bad handle sometimes, causes Chair lift is set to lose elevating function.

Utility model content

The technical problems to be solved in the utility model is to provide a kind of lifting chair, and the lifting chair is present by setting Fixation sliding part below chair manipulates the lifting of seat, which is hidden in seat in the following, user will not be because of Joyful or subconscious movement goes frequent operation seat to go up and down, and reduces the probability that cylinder heats up suddenly and explodes.In addition, The lifting of seat is manipulated by limiting sliding part and the connector combination of stroke, keeps the stress of gas valve only practical new with this The initial design parameters of valve lever are related in type structure, greatly reduce gas valve and lifting operating element because external force is damaged Bad probability.

The technical solution of the utility model is to provide a kind of lifting chair, the gas bar including being provided with stomata valve The pallet connecting with the gas bar is provided with seat apparatus for controlling of lifting on the pallet, the seat apparatus for controlling of lifting packet It includes sliding part, connector and the valve lever for opening the stomata valve, the sliding part and is slidably fitted in the pallet On, described connector one end is connected on the valve lever and the other end is connected on the sliding part.

After using the above structure, the lifting chair of the utility model has the advantage that compared with prior art

Since the seat apparatus for controlling of lifting of the lifting chair of the utility model includes sliding part, connector, the cunning Moving part is tightly attached on the pallet below seat, is hidden in seat in the following, being not easily seen, user will not in inessential situation The lifting of frequent de-regulation seat, eliminates security risk significantly.The sliding part has been defined stroke on pallet, greatly disappears Influence in addition to destructive external force to seat apparatus for controlling of lifting.

As an improvement, the pallet is equipped with slot, the sliding part, which is equipped with, is slidably fitted in the slot Interior raised line, the sliding part are located at the downside of the pallet.After adopting the structure, user is needing to adjust seat height It can grope the slide switch to the seat apparatus for controlling of lifting in under-seat at any time when spending.This structure simple realization The fit system of sliding part and pallet is that raised line slides in slot, specifies that the stroke of sliding part is limited by the slot. In addition, the fit system of sliding part and pallet can also be realized by sliding rail, i.e., it is provided with sliding rail on the pallet, it is described Be provided on sliding part with sliding rail mating structure or pulley, make that sliding part moves on the slide rail and stroke is limited by sliding rail.

It is equipped with as an improvement, being provided at least two raised lines being parallel to each other, the pallet on the sliding part Quantity is corresponding with the quantity of the raised line and the slot that is parallel to each other, the raised line cooperate correspondingly described Slot in.After adopting the structure, sliding part can be made to cooperate with pallet more firm, avoided in unilateral connection due to center of gravity It is indefinite that deviation rocks sliding part.

As an improvement, being provided with through-hole on the raised line, finite place piece, locating part limit are installed in the through-hole In the upside of the pallet.After adopting the structure, sliding part can be limited in the downside of pallet.Locating part herein can be with After so that screw rod and nut, screw rod is passed through the through-hole on raised line, both ends are secured with nuts.

As an improvement, the pallet is equipped with connection slot, the sliding part is equipped with connection raised line, the company It connects raised line to be slidably fitted in the connection slot, the other end of the connector is fixed on the connection raised line. The stroke that this structure connect connector without influencing sliding part with sliding part in the upside of pallet, avoids connector exposed.It answers It is to be independently arranged the position of fixedly connected part on sliding part with this structure, keeps each functional areas division of labor on sliding part clear.Such as Fruit is to set through-hole on the pallet, so that connector is passed through through-hole and connect with sliding part, then needs additional component or in cunning Special structure is arranged on moving part just can make connector not exposed.It but, can also be with for the connection raised line of fixedly connected part The raised line that other limits are slided on sliding part shares.

As an improvement, the connector is drag-line, which covers in drag-line pipe.The drag-line that this structure uses is flexible Connector, convenient for being connected in overall structure.And drag-line is solely subjected to pulling force, is combined with the sliding part for limiting stroke to manipulate The lifting of seat makes valve lever be solely subjected to the pulling force of horizontal direction, stress and the utility model knot of such gas valve The initial design parameters of valve lever are related in structure, unrelated with the size of active force that user applies, and greatly reduce ventilation Probability of the valve because of damage.

As an improvement, the first drag-line frame is equipped on the pallet at the position of the valve lever, it is described One end of drag-line pipe is mounted on the first drag-line frame, and end the first drag-line frame of perforation of the drag-line at the end is mounted on described Valve lever on；The second drag-line frame, the drag-line are equipped at the position of the connection slot on the pallet The other end of pipe is mounted on the second drag-line frame, and end the second drag-line frame of perforation of the drag-line at the end is mounted on described It connects on raised line.The mode of this structure simple realization drag-line connection sliding part and valve lever, strengthens the limit to drag-line, Guarantee that drag-line is not dislocated in loading process.

As an improvement, the sliding part is sliding block, the bottom surface of the sliding block is provided with suitable for the push plate of finger push or recessed Slot.It adopts the structure and not only facilitates operation, also substantially increase the comfort level of operation.Sliding part is also possible to the structure of comb teeth-shaped Part, comb part stretches out pallet, and limits on the upside of pallet, and downside can be the driving lever of rounded cap shape, and finger is facilitated to stir the cunning Moving part movement.

In addition, being also stamped the cover board bigger than tray area on the pallet, cover board is fixed by screws on pallet.This lid Plate uses steel construction, and gas bar explosion time can be effectively prevent to eject seat upwards and damage to user.
