Moving part is fixedly connected with.By pulling piece alignment pin can be driven to slide in slip cap, so as to adjust the lock of alignment pin and location hole
Determine relation.
In the rotatable handles mechanism of above-mentioned treadmill, the pulling piece is made as channel-shaped, and the alignment pin is connected in
On the side cell wall of pulling piece.Finger is extend in the groove of pulling piece during operation, and into the opposite side cell wall of pulling piece
Wall exerts a force, you can drive alignment pin to slide in slip cap by pulling piece, simple structure is easy to operate.
In the rotatable handles mechanism of above-mentioned treadmill, the outside of the fixed seat is arranged by the left shell being interlocked
And right shell body, the corresponding operating groove in the position between the left shell and right shell body after fastening with pulling piece.Left shell and the right side
Housing can avoid alignment pin, pulling piece etc. from exposing.
In the rotatable handles mechanism of above-mentioned treadmill, the position limiting structure includes the limit shaft being connected on handle
With the limiting plate in the fixed seat, the limit shaft is located at the sidepiece of rotating shaft, when a handle is rotated, limit shaft with handle around
The axial line for rotating shaft is rotated, and the limiting plate has for interting rotating shaft and limit shaft and for limiting limit shaft rotational angle
Spacing hole.Limit shaft and spacing hole are engaged, can avoid handle relative to fixed seat the infinite rotational in one direction, and lead
The built-in circuit of handle is caused to twist disconnected.
In the rotatable handles mechanism of above-mentioned treadmill, the spacing hole includes hole portion one and hole portion two, the hole
Portion one is made as semicircle, and the size of the hole portion one is adapted with rotating shaft, and the limit shaft is rotated in hole portion two.Rotating shaft is in hole
Freely rotate in portion one, locating shaft is rotated in hole portion two around the axial line of rotating shaft, and its movement locus is limited by hole portion two
It is fixed.
In the rotatable handles mechanism of above-mentioned treadmill, limit shaft setting parallel with rotating shaft, and limit shaft
Rotate in hole portion two.
Compared with prior art, the utility model has the following advantages that:
1st, the handle of this treadmill is connected in fixed seat by axis of rotation, then handle is waited when necessary can carry out turning
It is dynamic to fold, to reduce storage volume, it is to avoid damage;
2nd, the handle of this treadmill ensure that handle is tied after rotateing in place relative to fixed seat by arranging position limiting structure
Structure is stablized, and is difficult to rock, while handle can also be avoided excessive relative to fixed seat rotational angle and cause the built-in line of handle
Road twists disconnected.
