Common and practical body-building apparatus, is increasingly favored by people, and existing treadmill is in assembling and in use, starts mostly
Using foldable structure, in order to transport, use and deposit, such as Chinese patent【Application publication number is CN104759062A】It is disclosed
A kind of Zhan Shou mechanisms of treadmill, it is characterised in that：It is located at least between a column and pedestal of treadmill frame, treadbelt dress
Put and be incorporated on pedestal；The Zhan Shou mechanisms are fixed on the location-plate of column lower inside, a support handle, a fixation including one
Supporting plate on pedestal and the lock uint by supporting handle hand-motion；Column is pivotally connected with pedestal by location-plate and supporting plate
Together；Lock uint is to be located at the flexible lock pin on location-plate or in supporting plate, and is set on the supporting plate or on location-plate
The lockhole coordinated for lock pin, supporting handle hand-motion flexible lock pin and lockhole selective incubation.The parts of above-mentioned Zhan Shou mechanisms
It is more and complicated, adjustment inconvenience, and also the fastness of retaining mechanism is relatively low, influences the security used.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that a kind of column folding machine of treadmill
Structure, its technical problem to be solved is that the structure for the column fold mechanism for how causing treadmill is simple, easy to operate.
The purpose of the present invention can be realized by following technical proposal：A kind of column fold mechanism of treadmill, the race
Step machine includes frame and column, it is characterised in that the column fold mechanism includes adapter sleeve one, adapter sleeve two, adapter sleeve three
And bolt assembly, the adapter sleeve one are connected in frame, the column is connected on adapter sleeve two, the adapter sleeve one, is connected
Female connector two, adapter sleeve three are sequentially connected and concentric setting, the bolt assembly be interspersed in successively adapter sleeve one, adapter sleeve two,
On the axle center of adapter sleeve three, the adapter sleeve two can rotate relative to adapter sleeve one, and have between adapter sleeve two and adapter sleeve one
There is locking mechanism, spring is provided between the adapter sleeve three and adapter sleeve two.
When pushing out column, adapter sleeve two can be driven to be disconnected set one, after rotateing in place, unclamp column, even
Female connector two resets and locked again under the action of the spring.
In the column fold mechanism of above-mentioned treadmill, the locking mechanism includes being arranged on adapter sleeve one towards adapter sleeve
Several limited bayonets on two inner end face and adapter sleeve two is arranged on towards the positioning on one end end face of adapter sleeve one
Fixture block, the positioning wedged block are adapted with limited bayonet.When pushing out column, the positioning wedged block of adapter sleeve two can be driven to take off
From the limited bayonet of adapter sleeve one, after rotateing in place, column is unclamped, adapter sleeve two resets and causes positioning under the action of the spring
Fixture block is adapted with limited bayonet, is relocked, and the spacing of adjacent positioned bayonet socket is corresponding with the rotational angle of column.
In the column fold mechanism of above-mentioned treadmill, the other end end face of the adapter sleeve two towards adapter sleeve three has
Cavity one, the adapter sleeve three has the locating dowel one extended towards adapter sleeve two towards the inner end face of adapter sleeve two, described
Locating dowel one is slidably connected in cavity one, and the spring is located between the end face of locating dowel one and the bottom surface of cavity one.
In the column fold mechanism of above-mentioned treadmill, the limited bayonet includes edge one and edge two, the positioning
The opening ecto-entad of bayonet socket is gradually reduced, and the perpendicular setting in end face of the edge one and adapter sleeve one, the edge two
It is arranged in an oblique way with the end face of adapter sleeve one.After adapter sleeve two and adapter sleeve one engage, adapter sleeve two is only capable of inclining towards having
The side one-directional rotation of edge two tiltedly set, avoids turning round, mechanical stability is good, and connecting hole two is connected with cavity one.
In the column fold mechanism of above-mentioned treadmill, the limited bayonet includes edge one and edge two, the positioning
The opening ecto-entad of bayonet socket is gradually reduced, and the end face of the edge one and edge two with adapter sleeve one is arranged in an oblique way,
At least one positioning wedged block has the limit card block extended towards adapter sleeve one, has on the internal face of the adapter sleeve one
Along the circumferentially disposed limit card slot of adapter sleeve one.Limit card slot on the internal face of adapter sleeve one is curved, works as connection
After set two and adapter sleeve one engage, adapter sleeve two can be in the arc range of limit card slot relative to two-way turn of adapter sleeve one
Dynamic, the arc range of limit card slot is rotational angle range of the column relative to frame, easy to adjust.
In the column fold mechanism of above-mentioned treadmill, the adapter sleeve two has the locating dowel extended towards adapter sleeve one
Two, the adapter sleeve one has the cavity two for the locating dowel two that is slidably connected.When adapter sleeve two departs from relative to adapter sleeve one
