Description
Technical field
The invention belongs to the understructure technical field of support means, particularly relate to a kind of collapsible star base.
Background technology
Revolving chair leg, also known as star base, is the conventional accessory of swivel chair, office chair, in order to install lift cylinder and to support swivel chair,
Existing revolving chair leg is usually radioactive monolithic construction, so on the one hand when damaging occurs in one of them lower limb arm, just needs
To be replaced by whole star base, to cause unnecessary waste, on the other hand, its monolithic construction takes up room greatly, especially
Being that wasting space is many when depositing or casing transport, cost of transportation is high, adds the expenditure of enterprise.Existing folding easy to assemble
Although folded star base easily draws folding in, but the use intensity reducing star base the most in various degree, the most existing product
In product, draw the leg after folding in and be susceptible to come off with centrosome the phenomenon separated, give install next time add unnecessary
Troublesome operation, the most existing star base is also susceptible to be opened accidentally the problem that impact uses after gathering.
The Chinese invention patent that patent publication No. is CN 105124963 A, publication date is 2015.12.09 discloses one
Can receive star base, including centrosome and the lower limb arm that is arranged on centrosome, described centrosome is provided with corresponding with lower limb arm
Installation portion, described lower limb arm is hinged with installation portion, and described centrosome is provided with and limits the position-limit mechanism that lower limb arm rotates, by by lower limb arm
It is arranged to hinged with the connected mode of centrosome, and lower limb arm realizes by position-limit mechanism spacing fixing.
But the existence of this star base easily snaps off, it has not been convenient to the problem deposited and transport.
Summary of the invention
It is an object of the invention to provide a kind of collapsible star base, it can preferably draw folding in, and keeps drawing shape in
State is not opened accidentally, and it is firm that the present invention has simple in construction, and bonding strength is big, and conveniently and rounding state is steady to draw folding operation in
Surely the advantage being opened accidentally it is not susceptible to, to facilitate depositing and transporting of star base.
The present invention solves the problems referred to above and the technical scheme is that a kind of collapsible star base, including being provided with installing hole
