The utility model relates to a prison door arming mechanism, its boss on through the sear leads to the fact the displacement to the spline housing to the realization is disengaged the NOT AND and is disengaged, control simple and convenient, disengage moreover the in -process only need to rotate the handle rotate less angle can, the accessible stay cord is controld and is accomplished, raise the efficiency, but remote control.
Description
Technical field
The utility model is related to door lifter and frees technical field, especially a kind of prison door arming mechanism.
Background technology
The arming mechanism of existing door lifter, mostly its complex structure, substantially using a push rod by internal key top
Go out travelling gear, so as to realize being freed between travelling gear and power transmission shaft, but less stable during its use, easily go out
Existing failure etc..
Utility model content
The purpose of this utility model is to provide a kind of simple structure to solve the not enough of above-mentioned technology, frees more square
Just prison door arming mechanism.
In order to achieve the above object, a kind of prison door arming mechanism designed by the utility model, including free cylinder, solution
De- bar, be provided with the middle part of cylinder fixed cylinder freeing, and vertical between cylinder and fixed cylinder and both are interior for described freeing
Portion connects；Bearing (ball) cover and bearing are provided with cylinder two ends are freed, cylinder interior is freed splined shaft, described flower are provided with
One end of key axle is connected with the bearing for freeing cylinder one end, and power transmission shaft is provided with the bearing for freeing the cylinder other end, transmission
An axle part is located at frees cylinder interior, and a part is located at frees cylindrical outer, free the transmission shaft-side wall of cylinder interior to
Hollow cavity is inside provided with, bearing is provided with hollow cavity, be connected between the bearing and splined shaft, set on splined shaft
Spline housing is equipped with, is engaged by tooth type structures between the side wall and the lateral wall of the end of power transmission shaft of the end of spline housing；Spending
Check ring is provided with key axle, spring is provided between check ring and spline housing；In the circumference table of the outside of spline housing
Annular is provided with face frees groove, is provided with fixed cylinder and frees bar, and the side at the top of bar is freed boss is provided with,
Described boss is located at frees in groove；The boom end of freeing of fixed cylindrical outer is provided with swing handle.
Above-mentioned technical proposal, in bar rotation process is freed, frees the boss on bar in the axially displaced of splined shaft,
In moving process, boss drives spline housing to move in splined shaft, and compression spring, realize the tooth type structures of spline shaft end with
The tooth type structures of end part of driving shaft are separated, and complete to free；And from state of freeing to it is non-free State Transferring when, in spring
Under effect, spline housing is near power transmission shaft, while drive freeing bar rotation, and realizes the engagement of the tooth type structures on both；And
In the presence of spring so that both engage stable, stability height in power transmission process.
Be provided between bar position-limit mechanism fixing cylinder and freeing, position-limit mechanism is limited frees bar rotational angle.The knot
The design of structure, it is to avoid cause to interfere between spline housing and power transmission shaft and cause to damage because freeing bar rotational angle excessive.
Installing plate is provided with cylinder two ends are freed.
Prison door arming mechanism obtained by the utility model, it causes position by the boss freed on bar to spline housing
Move, free with non-so as to realize freeing, manipulation is simple and convenient, and only swing handle need to be rotated smaller angle during freeing
, can be manipulated by drawstring and be completed, efficiency is improved, it is remote controlled.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
