Description
Technical field
The present invention relates to swivel chair, office chair technical field, particularly to a kind of revolving chair leg that can dismount and group
Become the leg of revolving chair leg.
Background technology
Five-wheel rotatable chair, can make the rotation of vertical direction and the movement in orientation, so by numerous clerical workforces
Like.
Star base is the conventional accessory of swivel chair, is used for installing lifting air bar and supporting swivel chair.Existing star base
Owing to being actinomorphic monolithic construction, when vanning transport, taking up room big, wasting space is many, transport
Cost is high, and mould is big, and die cost is high.
Summary of the invention
Instant invention overcomes the deficiency in the presence of above-mentioned prior art, provide firstly propping up of a kind of revolving chair leg
Pin, this leg be composition revolving chair leg a unit, when vanning transport time, leg can be stacked together with
Save space；When needing after transport to destination to assemble, then formation one that 5 legs are stitched together
Complete revolving chair leg, dismounts very convenient.
The technical scheme is that and be achieved in that:
The leg of a kind of revolving chair leg, is provided with roller installing hole bottom one end of leg；One of the leg other end
Offer catching groove on side, and on the front end face of this one end, be provided with the button hook matched with catching groove.
As preferably, described button hook includes detaining tongue, and one end of button tongue and leg are provided with this one end of button hook
Front end face be connected, button tongue the other end be extended with snap fit towards the direction deviating from catching groove.Button tongue stretches into catching groove
After Nei, clamping bottom snap fit and catching groove, thus two legs can be linked together.
As preferably, the face residing for the entrance of catching groove is divided into two parts, respectively: leg is provided with button hook
The bearing surface that coordinates of the front end face of this one end and for forming the arc surface of chair pin centre bore；The shape of bearing surface
The front end face of this one end that shape, size and leg are provided with button hook matches, and arc surface is in bearing surface and props up
Between the front end face of this one end that pin is provided with button hook, bearing surface and arc surface phase intersection, arc surface again with
Pin is provided with the front end face phase intersection of this one end of button hook.Use such structure, when the button hook of a leg
When snapping in the catching groove of another leg, it is provided with the front end face of leg of button hook just and another leg
Bearing surface is seamless to be abutted together, and the arc surface of two legs can connect one bigger arc surface of formation,
After multiple legs are stitched together, it are formed for a complete revolving chair leg, and arc surface is spliced to form a use
Centre bore with slotting air inlet pole.
For the ease of splicing and convenient bearing surface is distinguish between with arc surface, as preferably, bearing surface and circle
It is protruding that the confluce of cambered surface forms one.When the front end face of leg is against on bearing surface, due to depositing of this projection
Will not move toward this direction of arc surface easily making leg.
As preferably, the central angle that described arc surface is corresponding is 72 degree.So, when 5 such spellings
After being connected together, 5 arc surfaces surround a circular centre bore.
As preferably, described button hook is 1～3, and corresponding catching groove is also 1～3.Can be according to reality
Needing to select the quantity of button hook, usually 1, processing is got up more convenient.
A kind of revolving chair leg, this revolving chair leg is to be assembled by 5 legs as above, adjacent two
In pin, the button hook of one of them leg snaps in the catching groove of another leg and makes adjacent two leg be connected to
Together, after 5 legs fit together, its junction surrounds a centre bore in order to slotting air inlet pole.
As preferably, when the button hook of one of them leg snaps in the catching groove of another leg, it is provided with button hook
The front end face of leg be abutted together with the bearing surface of another leg, and the arc surface of two legs connect
Forming a bigger arc surface, after 5 legs fit together, 5 arc surfaces surround one in order to insert
The centre bore of air inlet pole.
As preferably, being plugged with sleeve in centre bore, the upper end of sleeve pipe is provided with one along sleeve pipe radial direction
Outward extending flange, described flange is overlapped on the peripheral region of centre bore.Thus, leg be spliced into turn
After chair pin, sleeve of can planting in advance in centre bore, thus revolving chair leg is propped up, facilitate inserting of gas bar
Enter；Furthermore, owing to having flaw unavoidably man-hour adding, can cause in place of having corner angle or hollow inside centre bore
Exist so that gas bar and centre bore are difficult to fit tightly, and use middle meeting to cause and rock, so insertion sleeve pipe it
After, can be by sleeve pipe by swivel chair heel brace jail, and gas bar can closely cooperate with sleeve pipe so that gas bar with turn
The connection of chair pin is the most solid and reliable.
Have employed the principle of the present invention of technique scheme and provide the benefit that:
The dismounting revolving chair leg of the present invention is made up of 5 identical leg unit, and each leg unit comprises
One button hook and a catching groove, five leg cell rings are around circle one revolving chair leg of composition, first leg list
The button hook of unit and the catching groove of second leg unit fasten, the button hook of second leg unit and the 3rd leg
The catching groove of unit fastens, the like, the button hook of last 5th leg unit and first leg unit
Catching groove fastens, and forms one five-star revolving chair pin, and the arc surface composition one of five leg unit is complete
Centre bore, is used for filling in air inlet pole.
After taking seat due to people, seat is downward all the time to the active force of gas bar, and gas pole pair centre bore has all the time
One outside tension force, promotes the button hook of five leg unit and catching groove to fasten tighter, also makes whole assembly
Five-star revolving chair pin is more firm.
