Description
Technical field
The present invention relates to swivel chair, office chair technical field, particularly a kind of can dismounting revolving chair leg and form the leg of revolving chair leg.
Background technology
Five-wheel rotatable chair, can do the rotation of vertical direction and the movement in orientation, so be subject to liking of numerous clerical workforces.
Star base is the accessory commonly used of swivel chair, for the lifting air bar being installed and being supported swivel chair.Existing star base, owing to being actinomorphic monolithic construction, when the vanning transportation, takes up room large, and wasting space is many, and cost of transportation is high, and mould is large, and die cost is high.
Summary of the invention
The present invention has overcome existing deficiency in above-mentioned prior art, and at first a kind of leg of revolving chair leg is provided, and this leg, for forming a unit of revolving chair leg, when the vanning transportation, can be stacked together leg to save space; While needing to assemble after being transported to destination, then 5 legs are stitched together and form a complete revolving chair leg, dismounting is very convenient.
Technical scheme of the present invention is achieved in that
A kind of leg of revolving chair leg, a bottom section of leg is provided with the roller installing hole; Offer catching groove on a side of the leg other end, and be provided with the button hook matched with catching groove on the front end face of this end.
As preferably, described button hook comprises the button tongue, and an end of button tongue is connected with the front end face that leg is provided with this end of button hook, and the other end of detaining tongue is extended with snap fit towards the direction that deviates from catching groove.After the button tongue stretches in catching groove, snap fit and catching groove bottom clamping, thus two legs can be linked together.
As preferably, the residing face of the entrance of catching groove is divided into two parts, respectively: be provided with leg bearing surface that the front end face of this end of button hook coordinates and for forming the arc surface of chair pin centre bore; The front end face that the shape of bearing surface, size and leg are provided with this end of button hook is complementary, arc surface is provided with in bearing surface and leg between the front end face of this end of button hook, bearing surface and the intersection of arc surface phase, arc surface is provided with again the front end face phase intersection of this end of button hook with leg.Adopt such structure, when the button hook of a leg snaps in the catching groove of another leg, be provided with button hook leg front end face just and seamless being abutted together of bearing surface of another leg, and the arc surface of two legs can be connected to form a larger arc surface, just form a complete revolving chair leg after a plurality of legs are stitched together, and arc surface is spliced to form one in order to insert the centre bore of air inlet pole.
For the ease of splicing and facilitating, bearing surface and arc surface are distinguished, as preferably, the confluce of bearing surface and arc surface forms a projection.When the front end face of leg is against on bearing surface, because making leg, the existence of this projection can toward this direction of arc surface, not move easily.
As preferably, the central angle that described arc surface is corresponding is 72 degree.Like this, after 5 such being stitched together, 5 arc surfaces surround the centre bore of a circle.
As preferably, described button hook is 1～3, and corresponding catching groove is also 1～3.Can select according to actual needs the quantity of button hook, be generally 1, and 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, in two adjacent legs, the button hook of one of them leg snaps in the catching groove of another leg two adjacent legs is linked together, after 5 legs fit together, its junction surrounds one in order to insert the centre bore of air inlet pole.
As preferably, when the button hook of one of them leg snaps in the catching groove of another leg, being provided with the front end face of leg of button hook and the bearing surface of another leg is abutted together, and the arc surface of two legs is connected to form a larger 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, be plugged with a set of pipe in centre bore, the upper end of sleeve pipe is provided with one along the outward extending flange of sleeve pipe radial direction, and described flange is overlapped on the peripheral region of centre bore.Thus, after leg is spliced into revolving chair leg, the sleeve pipe of can planting in advance in centre bore, thus revolving chair leg is propped up, facilitate the insertion of gas bar; Moreover, owing to flaw being arranged unavoidably adding man-hour, can cause centre bore inside to have corner angle or hollow part to exist, make to bring about the desired sensation bar and centre bore is difficult to fit tightly, can cause and rock in use, so after inserting sleeve pipe, can be by sleeve pipe by swivel chair heel brace jail, and the gas bar can closely cooperate with sleeve pipe, thereby make the gas bar more solid and reliable with being connected of revolving chair leg.
Adopted principle of the present invention and the beneficial effect of technique scheme to be:
Dismounting revolving chair leg of the present invention is comprised of 5 identical leg unit, each leg unit comprises a button hook and a catching groove, five leg cell rings form a revolving chair leg around a circle, the catching groove of the button hook of first leg unit and second leg unit fastens, the catching groove of the button hook of second leg unit and the 3rd leg unit fastens, the like, the button hook of last the 5th leg unit and the catching groove of first leg unit fasten, form a five-star revolving chair pin, and the arc surface of five leg unit forms a complete centre bore, for filling in air inlet pole.
Due to after the people takes seat, seat is downward all the time to the active force of gas bar, and gas pole pair centre bore has an outside tension force all the time, impels the button hook of five leg unit and catching groove to fasten tighter, also makes whole assembled five-star revolving chair pin more firm.
