Description
Technical field
A kind of tube rolling device is the utility model is related to, more particularly, to a kind of slow cam mechanism of automatic hose reel.
Background technology
Existing automatic hose reel provides power by wind spring to reel, realizes that reel resets, and then realize the volume of flexible pipe
Around.But during rotation of reel, the reseting elasticity that wind spring provides is larger, causes rotation of reel speed.Hose end
Pipette tips easily cause whipping during hose reeling, are brought inconvenience to user.
Utility model content
The utility model is primarily directed to above mentioned problem, there is provided one kind effectively can slow down, to reel to flexible pipe retraction
Rotation reduction of speed, avoid due to reel at a high speed rotation cause potential safety hazard automatic hose reel slow cam mechanism.
The purpose of this utility model is mainly what is be achieved by following proposal：A kind of slow retraction machine of automatic hose reel
Structure, including the reel for convoluted hose, rotating disk is provided with the axis of reel, is provided with the end face of rotating disk same with rotating disk
The driving fluted disc of axle, driving fluted disc on the outside of be engaged with several driven gears, be provided with the end face of driven gear with it is driven
The coaxial travelling gear of gear, reel are provided with the side inner ring surface of travelling gear and travelling gear inscribe and engaged
Sliding tooth, the chute parallel to disk diameter direction is provided with rotating disk, slidably connects sliding block on chute, sliding block is away from rotating disk
The end face of axis is to lead to side inner ring surface radian identical rubbing surface of the reel away from travelling gear, several travelling gears
Linking arm is crossed to be connected.Reel is in rotation process, the mandrel geo-stationary at reel axis, during mandrel geo-stationary, linking arm
Geo-stationary, and reel is in rotation process, the sliding tooth on reel can rotate with nutating gear, travelling gear drive from
Moving gear rotates, and driven gear drives driving fluted disc to rotate, and sliding tooth dribbling turn disk rotates.Due to sliding tooth, travelling gear,
Driven gear is different with the number of teeth of driving fluted disc, and then make it that gearratio is different.It can be added using driven gear and travelling gear
The rotation of speed driving fluted disc, and then cause the rotating speed of rotating disk to be more than the rotating speed of reel, realize that rotating disk accelerates.As rotary speed increases
Greatly so that the sliding block on rotating disk has larger centrifugal force, and sliding block is subject to centrifugal forces to be directed away from axis along sliding block
Direction is slided, and now, rubbing surface of the sliding block away from axis one end can be bonded with side inner ring surface of the rotating disk away from travelling gear,
Using centrifugal force and fitting area, increasing friction force, using the frictional force between sliding block and reel, to reel reduction of speed, volume is realized
The slow retraction of disk.Whole device is different with the gearratio of travelling gear using driven gear, in the case where reel rotating speed is constant,
Accelerate the rotation of rotating disk so that sliding block has larger centrifugal force, and is reduced entirely using the frictional force between sliding block and reel
The rotating speed of reel, slow retraction is realized, avoids reel from running at high speed.
Preferably, linking arm is the centrosymmetric structure using the axle center of rotating disk as symmetrical centre.Linking arm is as positioning
Connector can ensure mandrel and the axis location of each travelling gear and driven gear, and then can convert the rotation of reel
For the rotation of driven gear and travelling gear, and ensure uniform force.
Preferably, driven gear is 2-4.
Therefore, a kind of slow cam mechanism of automatic hose reel of the present utility model possesses following advantages：Whole device utilizes
Driven gear is different with the gearratio of travelling gear, in the case where reel rotating speed is constant, accelerates the rotation of rotating disk so that sliding block
With larger centrifugal force, and using the rotating speed of the whole reel of frictional force reduction between sliding block and reel, slow retraction is realized, is kept away
Exempt from reel to run at high speed.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment 1：As shown in Figure 1, 2, 3, the slow cam mechanism of a kind of automatic hose reel, including the volume for convoluted hose
Disk 1, rotating disk 2 is provided with the axis of reel, the driving fluted disc 5 coaxial with rotating disk, sliding tooth are provided with the end face of rotating disk
Three driven gears 6 are engaged with the outside of disk, the travelling gear 7 coaxial with driven gear is provided with the end face of driven gear,
Reel be provided with the side inner ring surface of travelling gear with travelling gear inscribe and the sliding tooth 8 that engages, set on rotating disk
The chute 3 in disk diameter direction is parallel to, sliding block 4 is slidably connected on chute, end face of the sliding block away from rotating disk axis is
With side inner ring surface radian identical rubbing surface of the reel away from travelling gear, several travelling gears are connected by linking arm 9.
Linking arm is the centrosymmetric structure using the axle center of rotating disk as symmetrical centre.
Reel is in rotation process, the mandrel geo-stationary at reel axis, and during mandrel geo-stationary, linking arm is relatively quiet
Only, and reel in rotation process, the sliding tooth on reel can rotate with nutating gear, travelling gear drive driven gear
Rotate, driven gear drives driving fluted disc to rotate, and sliding tooth dribbling turn disk rotates.Due to sliding tooth, travelling gear, driven tooth
The number of teeth difference with driving fluted disc is taken turns, and then make it that gearratio is different.Driving is can speed up using driven gear and travelling gear
The rotation of fluted disc, and then cause the rotating speed of rotating disk to be more than the rotating speed of reel, realize that rotating disk accelerates.As rotary speed increases, make
Obtaining the sliding block on rotating disk has larger centrifugal force, and sliding block is subject to centrifugal forces to be directed away from axis direction cunning along sliding block
Dynamic, now, rubbing surface of the sliding block away from axis one end can be bonded with side inner ring surface of the rotating disk away from travelling gear, using from
Mental and physical efforts and fitting area, increasing friction force, using the frictional force between sliding block and reel, to reel reduction of speed, realize the slow of reel
Retraction.Whole device is different with the gearratio of travelling gear using driven gear, in the case where reel rotating speed is constant, accelerates to turn
The rotation of disk so that sliding block has larger centrifugal force, and reduces whole reel using the frictional force between sliding block and reel
Rotating speed, slow retraction is realized, avoids reel from running at high speed.Linking arm can ensure mandrel and each driving cog as positioning link
Wheel and driven gear axis location, and then can by the rotation for being converted into driven gear and travelling gear of reel, and
Ensure uniform force.
It should be understood that the embodiment is merely to illustrate the utility model rather than limitation the scope of the utility model.In addition
It should be understood that after the content of the utility model instruction has been read, those skilled in the art can make various to the utility model
Change or modification, these equivalent form of values equally fall within the application appended claims limited range.
