Description
Technical field
The invention belongs to field of exercise equipment, and in particular to a kind of tight latch mechanism of treadmill column folding.
Background technique
When using treadmill, height and front and back by height or the difference of use habit, for the station on column
There is the use position of different the most comfortable in position, and the position of station can pass through the angle tune between column and treadmill base
It is whole to realize, but the treadmill of existing column angle adjustable otherwise be relatively large complexity motorized adjustment form treadmill,
Structure is complicated, and the component costs of adjusting are also high, and existing simple treadmill frame does not have such regulatory function generally yet,
Even if having is also simultaneously inconvenient, the mode of operation trouble that operates.
Summary of the invention
The purpose of the present invention is provide a kind of treadmill column folding tight latch mechanism regarding to the issue above.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of treadmill column folds tight latch mechanism, column including treadmill, the treadbelt seat being connect with column bottom end with
And on the inside of treadbelt seat side and column bottom end between for the seat and detachable and with adjusting connect with column of run
Tight lock set, the tight lock set include exceeding the column inner surface towards on the inside of column through on the column
Front end have conical tooth colyliform conehead regulating part, be fixedly arranged on treadbelt seat side and backwards to treadbelt seat outer end in
Fixing piece with the cone cell wall section being adapted to the conehead and it can set to save land and connect regulating part and fixing piece so as to make to bore
Head is unclamped with cone cell wall section or locked stay bolt.
Fixing piece is unclamped or is locked with regulating part by stay bolt by the application, when locking on conehead and cone cell wall section
Tooth occlusion to not being able to rotate between column and treadbelt seat, when stay bolt unclamps, the tooth on conehead and cone cell wall section unclamps,
And stay bolt is not completely disengaged with fixing piece, so that column can rotate the angle for being conveniently adjusted column around treadbelt seat,
And then set the position of the station on whole treadmill.
Preferably, the fixing piece is partially submerged into the treadbelt seat, partially exceeds on the outside of the treadbelt seat, and the cone
Cell wall section is located on the collar extension beyond the treadbelt seating portion of the fixing piece.To guarantee the fixing intensity of fixing piece, together
When can also prevent fixing piece transition exceed treadbelt seat side, to influence the type size of entire treadmill.
Preferably, the fixing piece in along fixing piece axial direction and coaxially be successively arranged cone cell wall section, reseting groove section and
The thread segment being spirally connected with the stay bolt, the cone cell wall section, reseting groove section and thread segment bore successively reduce；Before the conehead
End, which extends forward, is equipped with boot segment, is equipped with the extrapolation spring being socketed on the boot segment in the reseting groove section.Pass through extrapolation
The setting of spring regulating part can be extrapolated automatically when stay bolt unclamps, so that the tooth on conehead and cone cell wall section unclamps so
Rear column can be rotated, easy to operate.
Preferably, being additionally provided with the guiding groove being adapted to the boot segment between the reseting groove section and the thread segment
Section.
Guiding groove section and boot segment cooperate, so that regulating part and fixing piece are stably maintained at when stay bolt is loosened or locked
Coaxial upper movement is not easy to block, service life is also longer to guarantee the convenience and reliability that adjust.
Preferably, the mouth that the reseting groove section outer diameter is greater than the guiding groove section is suitable, the extrapolation both ends of the spring difference
It is butted in the stage between the conehead front end and reseting groove section and the guiding groove section.
Preferably, the regulating part outer end face is flushed with the column lateral surface.
Preferably, the through-hole being adapted in the regulating part with the stay bolt includes the length being adapted to the tightening latch of stay bolt
Block in the nut that hole section and the widened nut head with the stay bolt on collar extension are adapted to.
Preferably, the length of block is greater than or equal to the length of the nut head of the stay bolt in the nut.
Entire nut is hidden when by the setting of above structure to can guarantee under at least normal locking state of column lower end
In in column, to guarantee integrally-built aesthetics, also it is not easy to get to.
Preferably, the length of the conehead is greater than the cone cell wall section thickness, and stay bolt locking regulating part and fixation
The front-end and back-end of part conehead all exceed the cone cell wall section.
Longer conehead structure, it is ensured that it smooth can be carried out when engagement or de- tooth, it is easy to operate, it is not easy to block.
Preferably, natural shape of the spacing between the column bottom end of treadbelt seat two sides when not connect with treadbelt seat
It is greater than the state when locking by stay bolt and treadbelt seat under state.
It is greater than spacing in the locked condition in the spacing of nature between column, only by column itself when locking
Light deformation locked i.e. column several millimeters of Light deformation under external force in stay bolt lock, and on the one hand while unclamping is spring
Effect resetted, the reset capability of another aspect column itself is resetted, to guarantee more convenient operation, regulating effect
It is good.
In conclusion the invention has the following advantages:
1, fixing piece and regulating part are unclamped or are locked by stay bolt by the application, conehead and cone cell wall section when locking
On tooth pine of the tooth occlusion to not being able to rotate between column and treadbelt seat, when stay bolt unclamps, on conehead and cone cell wall section
It opens, and stay bolt is not completely disengaged with fixing piece, so that column can rotate the angle for being conveniently adjusted column around treadbelt seat
Degree, and then set the position of the station on whole treadmill.
2, the application simple structure and convenient processing, at low cost, it is convenient to operate.
