Abstract
The utility model discloses a lifting device of a spring lifted revolving chair. The device mainly comprises support steel pipes, a lifting spring, strut steel bars, supporting disks, a locking turntable with a chute, a buffer spring, a supporting plate and the like; and the height of a chair can be adjusted by using lifting of the strut steel bars. When the device is used, the chair drives the strut steel bars and the locking turntable with the chute to rotate in the supporting disks; when the height is required to be adjusted, a box spanner is pressed down, so that locking bolts are loosened, and the strut steel bars can lift under the action of the springs; and after the height is proper, the box spanner is upwards forcibly fastened, and the strut steel bars are locked. Compared with the conventional revolving chair, the revolving chair with the device has the advantages that: because an explosion source does not exist, the hidden danger of explosion is eliminated, and the device is safe and reliable; the whole device is a common metal component, so the device is relatively simple in production process, low in cost and favorable for market popularization; and the lifting operation mode is similar to that of the conventional product, and the device is simple and easy to operate.
Description
Technical field
The utility model relates to field of furniture, relates in particular to a kind of spring hoisting type swivel chair lowering or hoisting gear.
Background technology
Along with computer constantly popularize the hommization more with the public place, the scope of application of swivel chair is increasing, not only various institutional settings, enterprises and institutions, company, industrial enterprise, school, army, Internet bar or the like all can use a large amount of swivel chairs; Computer is getting into huge numbers of families, also needs a large amount of swivel chairs; Before the window of public place, the bar desk is other also has a large amount of high swivel chairs to occur, and has brought many convenience for people's use.The explosion accident of swivel chair has report more, has juvenile quilt fried dead, has the Ms to be got in the body really startling, the fearful utmost point that causes by fried steel bar and a large amount of foreign material.Consult Baidu.com and the page or leaf of throwing the net 60 is arranged unexpectedly more in the relevant thing of talking about the swivel chair blast.According to the video that nearest CCTV plays, the expert analyzes the reason of blast, mainly possibly be that the purity of the body of inflating is not high in the air pressure rod, should fill highly purified nitrogen, possibly sneak into oxygen or aqueous vapor, have in addition what fill is air; Also possibly be that reasons such as the too thin or weldquality difference of air pressure rod tube wall are held hyperbar that can't stand moment and set off an explosion.Hyperbar can reach 24 atmospheric pressure under abnormal situation, expert's field trial, and under 7 atmospheric pressure, the butt end of steel bolt can puncture the plank that two layers of swivel chair are used, and 24 atmospheric pressure certainly can be more fearful, sees to such an extent that people tremble with fear.The structure more complicated of air pressure rod, require to reach material qualified, make that qualified, inflation etc. is all qualified to have a suitable difficulty.Last expert and host say, the regular product of regular producer, and quality is reliably, can relievedly use.Just mean that also the common low and middle-grade swivel chairs of informal manufacturer production just have not been easy to make commentary on the market, this swivel chair constantly comes into the market, and constantly gets into huge numbers of families, and this hidden peril of explosion can exist for a long time.The swivel chair that adopts air pressure rod is placed on huge numbers of families as if time bomb is placed on us at one's side, though the probability of its blast is lower, even 1,000,000/, the person of running into then is hundred-percent unlucky.
Urgent need is gone up with society in market, and some do not have the safe swivel chair of hidden peril of explosion! Also be badly in need of wanting the lower safe swivel chair of some prices.
Summary of the invention
The utility model provides a kind of spring hoisting type swivel chair lowering or hoisting gear; It mainly is made up of bearing steel pipe, lifting spring, pillar rod iron, supporting disk, the locking of band chute rotating disk, buffer spring and supporting plate etc., and it is characterized in that: the pillar rod iron inserts in the bearing steel pipe that has been placed with the lifting spring after putting buffer spring, supporting disk, band chute locking rotating disk.
Photocoagulation steel pipe in the bearing steel pipe adopts, the endoporus fineness of this steel pipe is better, only needs length intercepting on demand to get final product, and bearing steel pipe bottom is welded with base plate.
Promote spring and adopt cylindrical compression spring, the internal diameter of its external diameter and bearing steel pipe is suitable, and as preferably, the elastic force of spring is located between 5 kilograms to 35 kilograms, makes it can hold up and depress seat smoothly and regulates highly.
The pillar rod iron adopts the lower round steel of surface roughness, as does blasting treatment and can reduce roughness and also help coating and combine.Oblate steel plate of lower end welding of round steel, the internal diameter of the external diameter of oblate steel plate and bearing steel pipe is suitable; The upper end of round steel processes a cylinder step and has attacked screw, and the external diameter of cylinder step and supporting plate aperture are suitable, and the size and the fastening bolt of screw are suitable.
Supporting disk is welded by short steel pipes and circular steel plate; The external diameter of the internal diameter of short steel pipes and bearing steel pipe is suitable; The endoporus of circular steel plate and the external diameter of pillar rod iron are suitable, and the threadless dog screw of head is established on supporting disk top, and the bottom establishes fastening bolt and the bearing steel pipe is fixed.
Band chute locking rotating disk is made up of locking rotating disk, clamping screw, double off-set spanners etc.Establish the locking screw keyhole on the locking rotating disk, adopt high-strength bolt as preferred clamping screw.The locking rotating disk is placed in the supporting disk, and its external diameter and supporting disk internal diameter are suitable, and the endoporus of locking rotating disk and the external diameter of pillar rod iron are suitable, and when clamping screw was tightened, the pillar rod iron was lockable, and when clamping screw unclamped, the pillar rod iron can go up and down.Locking rotating disk bottom has chute, and the dog screw on the supporting disk gos deep in the chute, places restrictions on it and can only rotate and can not move up and down.Double off-set spanners has 12 angles, and when regulating the bolt degree of tightness, the selection of setting angle is comparatively convenient, if adopt special-purpose double off-set spanners, about handle deflection 8 degree, selectable angle is more.Double off-set spanners is located at the below, seat, and the mode of regulating height is similar with common swivel chair.
Buffer spring is enclosed within pillar rod iron bottom, and the external diameter of its internal diameter and pillar rod iron is suitable.When seat unclamps clamping screw under uncharge state, the impact that buffer spring ability damper leg rod iron makes progress.
Adopt bolted to connect between pillar rod iron and the supporting plate.
The seat band the pillar rod iron and is with chute locking rotating disk in supporting disk, to rotate during use, when needs are regulated height, presses double off-set spanners clamping screw is unclamped; The pillar rod iron is liftable under the effect of spring; After highly suitable, the fastening double off-set spanners of up exerting oneself, the pillar rod iron is locked.
The utility model is compared with original swivel chair, and the utility model does not have explosive source, has eliminated hidden peril of explosion, and is safe and reliable; Whole device is common metal parts, and production technology is also simpler, and cost is lower, and favourable marketing is popularized; The descending operation mode is similar with existing product, and is simple to operation.
