Description
Technical field
The present invention relates to fitness equipment component fields, and in particular to a kind of multifunctional transmission device.
Background technique
Multifunctional transmission device is widely used in exercycle, body-building rowing machine, comprehensive due to having can be realized transmission separation
It closes on the multi-functional equipment such as training aids.
Existing multifunctional transmission device generally includes shaft, unilateral bearing, ribbon, ribbon disk and dampened disk, ribbon disk peace
In shaft, ribbon disk is connected by unilateral bearing with drive disk, and for braided strap winding on ribbon disk, dampened disk and drive disk are logical
Cross V belt translation.When being applied to rowing machine, handle is connected with ribbon, when user pulls ribbon by handle, ribbon
The rotation of ribbon disk is driven, at this point, unilateral bearing is in locking state, ribbon disk can drive drive disk to rotate, and drive disk drives again
The rotation of dynamic damping disk, dampened disk provide resistance in turn for ribbon, when the revolution of ribbon disk, since the separation of unilateral bearing is made
With the revolution of ribbon disk and the rotation of drive disk are non-interference.In this way, user cooperates during pull handle and return
The sliding of cushion forms the movement imitated and rowed the boat.
However, existing multifunctional transmission device is although carried out transmission point to drive disk and ribbon disk in the revolution of ribbon disk
From, but it can not separate the transmission between drive disk and shaft, when drive disk rotates (it is assumed that rotating clockwise), shaft meeting
Drive disk is followed to be rotated；And when shaft is towards when rotating counterclockwise, shaft can drive drive disk rotation (counterclockwise), in turn
Ribbon disk is influenced, ribbon disk is caused to interfere.
Other than the defect on multifunctional transmission device, there is also following defects for existing body-building rowing machine: due to imitating
When boating, handle and cushion are non-in stationary state, and therefore, foot becomes main sticking point, but existing body-building
Pedal in rowing machine cannot be adjusted according to the size of the sole of user or the flexible in size of shoes, and there are slippage hidden danger；
Meanwhile the tilt angle of pedal is difficult to be adjusted, it is difficult to be applicable in the long user of different heights, leg.
Summary of the invention
The purpose of the present invention is to provide the multifunctional transmission devices that one kind can be effectively isolated ribbon interference.
To achieve the above object, the invention adopts the following technical scheme:
A kind of multifunctional transmission device, including shaft, drive disk, unilateral bearing, wheel case, single direction ratchet, ribbon and knit
Tep reel；The shaft is rotatably installed in institute's rack to be mounted, and the wheel case is mounted on described turn by the unilateral bearing
On axis, the drive disk connects one end of the wheel case, and the inner ring of the single direction ratchet connects the other end of the wheel case, described
The outer ring of single direction ratchet is connected with the ribbon disk, and the ribbon is on the ribbon disk；The separation of the unilateral bearing
Direction is the draw direction of the ribbon, and the detaching direction of the single direction ratchet is the backrush direction of the ribbon.
The present invention also provides a kind of body-building rowing machines comprising rack, pedal and cushion further include damping unit and handle
Hand, the damping unit include dampened disk and multifunctional transmission device above-mentioned, and the dampened disk and the drive disk pass through skin
V belt translation, the handle are connected to pull the ribbon with the end of the ribbon.
