Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment one: ginseng as shown in FIGS. 1 and 2, a kind of transmission device, including rack 1, the motor being set in rack 12, pass
Lever 3 and limiting device, one bearing 4 of the middle part rotational installation of the drive rod 3 in the rack 1, the drive rod 3
Right side outer edge surface is equipped with a spline 5, and the left side of the drive rod 3 is equipped with a turntable 6, and the turntable 6 and the drive rod 3 are same
Axis setting, the output shaft of the motor 2 are connected with the left side of the drive rod 3;The limiting device includes top position-limit mechanism
And lower limit mechanism, the top position-limit mechanism are set to the surface of the turntable, the lower limit mechanism is set to
The underface of the turntable, the top position-limit mechanism include telescopic cylinder 7 and briquetting 8, the top center of the briquetting 8 with
The output shaft of the telescopic cylinder 7 is connected, and the bottom surface of the briquetting 8 is equipped with rubber antiskid layer 9, the telescopic cylinder output shaft
Under stretching state, the rubber antiskid layer is butted on the top outer edge surface of the turntable, the telescopic cylinder output shaft retraction shape
Under state, the rubber antiskid layer is set to the surface of the turntable;The outer edge surface of the turntable 6 is equipped with a notch 10, institute
Stating lower limit mechanism includes gag lever post 11 and limiting cylinder 12, and the bottom of the gag lever post 11 is defeated with the limiting cylinder 12
Shaft is connected, and the gag lever post 11 is arranged perpendicular to the axis of the turntable 6, and the gag lever post 11 is set to the turntable 6
Underface, the rack 1 are equipped with a stop collar 13, and the middle part of the gag lever post 11 is inserted in the stop collar 13, described
Under 12 output shaft retracted state of limiting cylinder, the underface of the turntable, the limit gas are set at the top of the gag lever post
Under cylinder output shaft stretching state, it is inserted at the top of the gag lever post in the notch.
In the present embodiment, when in use, it is connect on the right side of drive rod with traction mechanism or rolling-up mechanism, passes through motor band
Dynamic drive rod rotation, so that traction mechanism or rolling-up mechanism be driven to rotate, in this process, turntable can also move therewith,
After motor stopping, since product has certain screen resilience, product is sprung back in order to prevent, utilizes upper and lower part position-limit mechanism
Turntable is limited, that is, drive rod is limited, prevents drive rod from being rotated.Wherein after motor stopping, stretch
The output shaft of contracting cylinder stretches out, and drives briquetting and rubber antiskid layer to push, is pressed on the top outer edge surface of turntable, utilizes rubber
Frictional force between anti-slip layer and turntable slows down the revolving speed of turntable, meanwhile, turntable slow down during, limiting cylinder it is defeated
Shaft also stretches out, and increase gag lever post, and the top of gag lever post is first butted on the bottom outer-edge face of turntable that (notch is being not necessarily just at this time
To gag lever post), when notch face gag lever post on turntable, due to the stretching of limiting cylinder output shaft, it can make to limit in this way
Position bar is inserted into notch, using the clamping engagement of gag lever post and notch, makes rotary disk limitation, turntable can not be rotated, be passed at this time
Lever can not also rotate, and realize the limit of drive rod.By the setting of stop collar, prevent the output shaft of limiting cylinder by transverse direction
Thrust guarantees the service life of limiting cylinder.
Ginseng as shown in FIGS. 1 and 2, the top of the gag lever post 11 is equipped with an idler wheel 14, and the rotational installation of idler wheel 14 is in described
The top of gag lever post 11, the top outer edge surface of the idler wheel expose to the top of the gag lever post, the top of the limit and institute
Stating idler wheel can be inserted in the notch.
The width of the notch is greater than the diameter of the idler wheel, and the depth of the notch is greater than or equal to the straight of the idler wheel
Diameter.
In the present embodiment, when rising due to gag lever post, the notch of turntable may not face gag lever post, in this way limit
When bar rises, the top of gag lever post can touch the bottom outer-edge face of turntable, can thus generate rigid friction, cause to turn
Disk and gag lever post are worn, and can also generate noise, and by the setting of idler wheel, when gag lever post rises, idler wheel, which can be against, to be turned
On the outer edge surface of disk, idler wheel and turntable rolling friction are not in abrasion, noise will not be generated, when notch is contacted with idler wheel
When, due to the thrust that limiting cylinder output shaft stretches out, the top of such idler wheel and gag lever post will be inserted into notch, right
Turntable is limited, and the rotation of turntable is prevented.
Shown in Figure 1, the bottom of the briquetting 8 is equipped with a T-slot 15, and the top of the rubber antiskid layer 9 is equipped with a T
Type protrusion 16, the rubber antiskid layer are inserted in the T-slot through the T-type protrusion, are installed on the rubber antiskid layer
The bottom of the briquetting.Wherein, bolt can be also set on briquetting, and the end of bolt is directly inserted into T-slot, in this way being capable of benefit
T-type protrusion is limited with bolt, guarantees the locking quality of rubber antiskid layer.
In the present embodiment, since rubber antiskid layer can often contact friction with turntable, abrasion, such rubber are easy to appear
Anti-slip layer needs to be replaced frequently, by the setting of T-slot and T-type protrusion, convenient for the replacement of rubber antiskid layer.
