Technical field

It is the utility model relates to dormitory consumer goods industries, in particular to a kind of for fixing the folding retractable branch of chair lift Frame.

Background technique

In university life, dormitory chair lift is relatively conventional daily necessity.Students' dormitory chair is mostly wooden hard chair, is seated It is uncomfortable, but continuous arm-chair is more expensive, and this homemade student's chair lift is just come into being.But student's chair lift now on the market is most Be fixed point above, lower section can shake, and can want to write to student or when operation makes troubles, so needing a kind of energy Enough demands according to user can be fixed from main regulation folding retractable bracket, guarantee that student being capable of use chair lift freely.

Currently, the Chinese patent of Publication No. CN203468066U discloses a kind of hanging chair stand comprising hold pendant and Pedestal, close hold in the pedestal inside are connected equipped with pedestal described in cross bar by two or more base mounting members at pendant It forms, the base mounting member that the pedestal is mutually mirrored by two is formed by connecting, and base mounting member is equipped with along the symmetry axis of pedestal It can be used for connecting the mounting bar of base mounting member, mounting bar both ends are separately connected cross bar and base mounting member.

Although this hanging chair stand structure is simple, low in cost, it is easy production, plays chess chair lift not for this bracket It can play and be effectively protected and support, and flexible modulation cannot be carried out according to the demand of user, not be able to satisfy the daily of user Demand.

Utility model content

The purpose of the utility model is to provide a kind of for fixing the folding retractable bracket of chair lift, and having can be according to making The demand of user fix chair lift bottom from main regulation, and sitting posture is allowed to keep stablizing the advantages of not generating shaking.

The above-mentioned technical purpose of the utility model has the technical scheme that

It is a kind of for fixing the folding retractable bracket of chair lift, including chair lift ontology, the chair lift body bottom portion is equipped with solid Surely the support plate connected, the support plate bottom side are equipped with two piece of first connecting plate, two piece of first connecting plate inner wall It is equipped with the first rotating bar, the second rotating bar of rotation connection, passes through at first rotating bar and the second rotating bar center and turns Moving axis is hinged, and first rotating bar and the second rotating bar bottom are equipped with the bottom plate being slidably connected, and the support plate bottom is another Side is equipped with two piece of second connecting plate, and two piece of second connecting plate inner wall is equipped with the third rotating bar of rotation connection, the 4th turn It is hinged at lever, the third rotating bar and the 4th rotating bar center, the third rotating bar and the 4th rotating bar bottom Also it is slidably connected with bottom plate；The main support being fixedly connected with support plate is equipped between first connecting plate and the second connecting plate Frame, the main backstop are equipped with ball-screw being rotatablely connected and straight down, and the ball-screw both ends are equipped with mutual Parallel connecting rod, the ball-screw are equipped with sliding shoe, and the sliding shoe runs through ball-screw and two lateral connector bars, described Ball-screw and connecting rod bottom are equipped with secondary support frame, and the sliding shoe both ends are equipped with the mandril being fixedly connected, the mandril bottom Portion is fixedly connected with bottom plate.

By using above-mentioned technical proposal, now chair lift on the market be mostly fixed point above, can shake, however When student wants to write, the chair lift of shaking does not have stability, will affect normally doing things for student, student can pass through at this time The ball-screw between main backstop and secondary support frame is rotated, so that the sliding shoe being located on ball-screw moves down, meanwhile, The mandril of sliding shoe two sides being fixedly connected pushes down on bottom plate until contacting ground, while the first rotating bar of two sides, the Two rotating bars rotate together certain angle, and between angle become smaller, the first rotating bar is slided together with the second rotating bar bottom And mutually draw close, similarly third rotating bar is rotated together with the 4th rotating bar and bottom is mutually drawn close, when mandril pushes bottom plate to connect After tread surface, the first rotating bar, the second rotating bar, third rotating bar and the 4th rotating bar play support protection support plate and bottom The effect of plate ensure that student when writing, and rocking chair bottom can fix reduction relatively and shake, and enable student quiet conscientious It writes on ground.

Further setting: first rotating bar, the second rotation, third rotating bar and the 4th rotating bar bottom are all provided with hinged The shaft seat connect, the bottom plate are equipped with the sliding slot being slidably connected with shaft seat.

By using above-mentioned technical proposal, when sliding shoe, which moves down, drives mandril that bottom plate is pushed at ground, two The shaft seat of side slides and close to other side on bottom plate.

Further setting: the bottom base plate is equipped with several support legs, and the support leg surface is equipped with dirt-proof boot, described Dirt-proof boot bottom is equipped with several anti-skidding salient points.

By using above-mentioned technical proposal, after bottom plate is close to ground, support leg and ground face contact can be played effective The dirt-proof boot of stabilization, surface can prevent dust also waterproof, avoid prolonged use that from damaging and soak support leg, and The anti-skidding salient point of dirt-proof boot bottom is capable of increasing frictional force, enables chair lift is more stable to be fixed on ground.

Further setting: the support plate two sides are equipped with hinged fixation gag lever post, the fixed gag lever post bottom peace It is located at fixed gag lever post hinged place equipped with the first magnet block, on the bottom plate and is arranged right below the second magnet block.

By using above-mentioned technical proposal, after mandril drives contacts baseplate ground, student can rotate fixed gag lever post 90 degree, by fixed gag lever post bottom and contacts baseplate, the first magnet block and the second magnet block of fixed gag lever post bottom are mutual Absorption, ensure that and be able to maintain stabilization between support plate and bottom plate, increase the resistance to compression load-bearing capacity of bracket.

Further setting: the ball-screw bottom is equipped with the manual adjustment wheel being fixedly connected, the manual adjustment wheel table Face is equipped with slip-resistant texture.

By using above-mentioned technical proposal, student can drive ball-screw rotation by manual adjustment wheel, convenient and efficient.

Further setting: support plate two sides side wall is equipped with metal iron plate.

By using above-mentioned technical proposal, when not needing using bracket, the fixation gag lever post of two sides can rely on magnetic force Absorption is fixed on support plate side wall, will not influence user's normal use chair lift.

In conclusion the utility model has the following beneficial effects: this bracket can be carried out according to the demand of user Folding retractable, user by manually adjusting, chair lift bottom can be connect with ground and it is relatively fixed firmly, ensure that makes User can be when using chair lift, and sitting posture keeps relative stability, and also shrinkable adjusting when empty not using, and will not occupy sky Between, it is convenient and strength-saving, there is certain practicability.
