Embodiment
Star base embodiment can be stored referring to figs. 1 to Fig. 7 to the present invention to be described further.
Structure chart when being as shown in Figure 1 star base normal operating condition, it includes 5 leg arms 1 and centerbody 2, leg
Arm 1 is uniformly distributed in the side wall of centerbody 2, and centerbody 2 is provided with installation portion 3 corresponding with leg arm 1, and leg arm 1 is cut with scissors with installation portion 3
Connect, centerbody 2 is provided with the position-limit mechanism that limitation leg arm 1 rotates；
Wherein position-limit mechanism includes upper limit assembly and lower limit component, and lower limit component includes what is fixed with centerbody 2
Chassis 4, chassis 4 are provided with mounting bar 41 corresponding with leg arm 1, and mounting bar 41 is fixed in leg arm 1, and upper limit assembly includes setting
In the fixed block 5 of centerbody 2, fixed block 5 is corresponding with leg arm 1 and contradicts, and specific structure is as shown in figures 1 and 3.
The connected mode of leg arm 1 and centerbody 2 is arranged to be hinged by such setting, and leg arm 1 passes through upper limit
The fixed block 5 of component props up leg to prop up the limitation that leg arm 1 realizes a rotation direction, then by the chassis 4 of lower limit component
Arm 1 realizes the limitation of another rotation direction, so as to realize comprehensively it is spacing come Convenient table arm 1, ensure star base use when can
Normal use, when not in use, chassis 4 need to only be disassembled to can upset leg arm 1 and store its whole, saving accounts for
With space, it is easy to deposit and transports, reduces cost of transportation, save the expenditure of enterprise, it is necessary to need to only be overturn leg arm 1 when using
Chassis 4 is reinstalled again to original position and can be achieved with fixing, whole operation process is very simple and convenient quick, time saving and energy saving,
Concrete structure is as shown in Figure 2.
Further, chassis 4 is provided with the flange 42 contradicted with the bottom wall of centerbody 2, and flange 42 is fixed with centerbody 2, bottom
Be provided with reinforcement block 43 between disk 4 and mounting bar 41, preferably flange 42, chassis 4, mounting bar 41 and reinforcement block 43 be integrally formed and
It is made by stainless steel, is so on the one hand easy to process, not only structural strength is high for another aspect stainless steel material, and
And it is durable be less prone to situations such as getting rusty, the flange 42 on chassis 4 is fixed with the end face of centerbody 2 by screw 8, mounting bar 41 and leg
Arm 1 is fixed again by screw 8, by setting the reinforcement structure intensity of reinforcement block 43 in the junction of leg arm 1 in mounting bar 41, because
Stress concentration be present for junction, intensity requirement can be relatively higher, and limited reinforcement block 43 is triangle, and consolidation effect is more preferably prominent
Go out, detailed construction is as shown in figs. 4 and 7.
Wherein leg arm 1 realizes that pin 6 is worn on installation portion 3, and pin 6 runs through by pin 6 with the be hinged of installation portion 3
Leg arm 1, the both ends of pin 6 are equipped with annular groove 61, spacing jump ring 62 are provided with annular groove 61, so as to realize the hinge of leg arm 1 and installation portion 3
Connect, whole articulated structure is simple, while also achieves being detachably connected for leg arm 1, when running into indivedual leg arms 1 and damaging without
Whole star base need to be changed, the leg arm 1 of damage need to only be disassembled and carry out replacing can, concrete operations only need to be by pin 6
The spacing jump ring 62 at both ends is disassembled, and pin 6 is extracted out and can be achieved with dismantling, and specific operation process is simple and convenient quick, saves
Shi Shengli, so as to avoid unnecessary waste.
Further, the bottom wall of leg arm 1 is provided with and empties portion 11, empties in portion 11 and is provided with and 41 corresponding mounting post of mounting bar
12, mounting bar 41 and mounting post 12 are provided with corresponding mounting hole, and the side wall of mounting post 12 is provided with the stiffener 13 of right-angled intersection, leads to
The setting for crossing the portion of emptying 11 can be largely saving production cost, mounting post 12 is provided with screwed hole, passes through mounting post
12 realize the fixation of leg arm 1 and mounting bar 41, and the stiffener 13 of right-angled intersection can strengthen the structural strength of mounting post 12, avoid
The situation that screw 8 is twisted during removing and installing causes mounting post 12 to occur damaging or be broken occurs.
Further, installation portion 3 is distributed around the even circumferential of centerbody 2, and installation portion 3 includes spaced installing plate 31,
Installing plate 31 is arranged at intervals, on the one hand increases the ratio that installation portion 3 accounts for the circumference of centerbody 2, increases mounting stability, the opposing party
Face also allows for the installation of leg arm 1 and pin 6, and then it is 5 and equally around the even circumferential of centerbody 2 that leg arm 1 is corresponding
Distribution so that it is more uniform during its stress again, and also leg arm 1 is inclined to set, and the upper surface of leg arm 1 is arcwall face 14, inclined
The leg arm 1 of setting is had bigger bearing capacity by vertical direction power, can bear bigger limiting pressure, leg arm 1
The curved face 14 in surface, it is not only more attractive in appearance that there is curved surface U.S., and reduce stress concentration and be less prone to slight crack, while also avoid
Hand is scratched when carrying and hand are taken.
Further, leg arm 1 is provided with the supporting part 7 being vertically arranged away from the one end of centerbody 2, and supporting part 7, which is provided with, to be used
In the blind hole 71 of installation castor, by the setting of supporting part 7, when star base is not attached on swivel chair, supporting part 7 can be passed through
Stable placement, be not in situation about toppling over, while the bottom of supporting part 7 setting blind hole 71 is easy to the installation of later stage castor.
Specific assembling process：Chassis 4 is first enclosed on the one end of centerbody 2, and by screw 8 by the flange 42 on chassis 4 with
Heart body 2 is fixed one by one, and then each leg arm 1 is installed successively, and prior installation chassis 4 can carry out certain to leg arm 1
Supporting role, it is easy to the installation of leg arm 1, first leg arm 1 is placed at installation portion 3 during installation leg arm 1, then by pin 6
It is located at outside through leg arm 1 and installing plate 31 and the annular groove 61 at both ends, then the built-in upper limit jump ring 62 of the annular groove 61 at both ends
Realize spacing, complete that after leg arm 1 installs, the mounting post 12 on the mounting bar 41 on chassis 4 and leg arm 1 finally is passed through into screw 8
It is fixed one by one, it is simple and convenient quick so as to complete whole assembling process.
Described above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that for the art
Those of ordinary skill for, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications
