More, and structure is complicated, adjustment is inconvenient, and the fastness of retaining mechanism is lower, influence using safety.The applicant exists
2017 once applied for a patent [Patent No. ZL2017215671883], although it enables to operate relatively easy convenience,
But since limit card slot to be arranged on the inner wall of connector sleeve, it is easy so that the wall thickness of connector sleeve is relatively thin, structural strength phase
To weaker, service life is influenced.
Summary of the invention
The purpose of this utility model is the presence of the above problem in view of the prior art, is proposed a kind of for the vertical of treadmill
Column fold mechanism, it the technical problem to be solved is that how making the structure of the column fold mechanism for treadmill simple,
It is easy to operate.
The purpose of this utility model can be realized by the following technical scheme: a kind of column folding machine for treadmill
Structure, the treadmill include rack and column, and the column fold mechanism includes connector sleeve one, connector sleeve two, three and of connector sleeve
Bolt assembly, the connector sleeve one are connected on the rack, and the column is connected on connector sleeve two, the connector sleeve two and connection
There is locking mechanism between set one, and connector sleeve two can be rotated relative to connector sleeve one, the connector sleeve three and connector sleeve two it
Between be provided with spring, which is characterized in that the locking mechanism includes that inner end end face of the connector sleeve one towards connector sleeve two is arranged in
On several limited bayonets and connector sleeve two is set towards the positioning wedged block on one end end face of connector sleeve one, the positioning
Fixture block is adapted with limited bayonet, has the limit for outwardly protruding and extending towards connector sleeve two in the outside wall surface of the connector sleeve one
Position fixture block one has in the outside wall surface of the connector sleeve two and outwardly protrudes and towards the limit card block two that connector sleeve one extends, institute
It states limit card block two and limit card block one is adapted.
When pushing out column, the positioning wedged block of connector sleeve two can be driven to be disconnected from sleeve one limited bayonet, when turn
After moving in place, column is unclamped, connector sleeve two resets under the action of the spring and positioning wedged block is adapted with limited bayonet, again
Locking, the spacing of adjacent positioned bayonet and the rotational angle of column are corresponding, and limit card block one and limit card block two are set respectively
Both it sets in the outside wall surface of connector sleeve one and connector sleeve two, it is ensured that the wall thickness of connector sleeve one and connector sleeve two, guarantee
Structural strength avoids damaging.
In the above-mentioned column fold mechanism for treadmill, the limit card block one outwardly protrudes connector sleeve one towards even
The end face of female connector two, the limit card block two outwardly protrude connector sleeve two towards the end face of connector sleeve one.When connector sleeve two and even
When female connector one pulls open separation relatively, limit card block one and limit card block two can also play position-limiting action.
In the above-mentioned column fold mechanism for treadmill, the number of the positioning wedged block is two, two positioning cards
Block is arranged in the outside wall surface of positioning wedged block with the center symmetric setting of connector sleeve two, the limit card block two, the positioning card
Mouth is even number, and limited bayonet is symmetrical arranged in pairs with the center of connector sleeve one.
In the above-mentioned column fold mechanism for treadmill, between two adjacent limited bayonets have positioning every
Block, the limit card block one are located in the outside wall surface of positioning spacer block.
In the above-mentioned column fold mechanism for treadmill, the connector sleeve one, connector sleeve two, connector sleeve three successively phase
Even and concentric setting, the bolt assembly are successively interspersed on the axle center of connector sleeve one, connector sleeve two, connector sleeve three.Upper
It states in the column fold mechanism for treadmill, the connector sleeve two has cavity one, the company towards the end face of connector sleeve three
Female connector three has the positioning column one extended towards connector sleeve two towards the inner end end face of connector sleeve two, and the sliding of positioning column one connects
It connects in cavity one, the spring is located between the end face of positioning column one and the bottom surface of cavity one.
In the above-mentioned column fold mechanism for treadmill, the limited bayonet includes edge one and edge two, described
The opening ecto-entad of limited bayonet is gradually reduced, and the perpendicular setting in end face of the edge one and connector sleeve one, the card
The end face of Bian Eryu connector sleeve one is arranged in an oblique way.After connector sleeve two and connector sleeve one engage, connector sleeve two is only capable of towards tool
There is two side of edge being obliquely installed one-directional rotation, avoids turning round, mechanical stability is good, and connecting hole two is connected with cavity one.
In the above-mentioned column fold mechanism for treadmill, the limited bayonet includes edge one and edge two, described
The opening ecto-entad of limited bayonet is gradually reduced, and the edge one and edge two are tilted with the end face of connector sleeve one and set
It sets, at least one described positioning wedged block has the limit card block that extends towards connector sleeve one, on the inner wall of the connector sleeve one
With the limit card slot being circumferentially arranged along connector sleeve one.Limit card slot on one inner wall of connector sleeve is arc-shaped, when
