The utility model provides a rolling slats door counter weight device, concrete technical scheme is as follows:
the counterweight device of the rolling door comprises a reel, a pull rope, a pulley and a hook frame,
the fixed sleeve of the reel is arranged on one side of a rolling mechanism of the rolling door, one side of the reel is provided with a guide wheel, the guide wheel and the reel are arranged at intervals, one end of the stay cord is wound on the reel to form a traction end, the other end of the stay cord is sequentially wound on the guide wheel and the pulley and is fixedly arranged to form a fixed end, and the fixed end is positioned above the hook rack,
the pulley is located the reel with between the stiff end, couple frame fixed mounting be in rolling slats door's bottom one side, the pulley through one or more extension springs with the couple frame is connected.
In some embodiments, the reel is tower-shaped or cylindrical.
In some embodiments, the hook frame is evenly provided with a plurality of hook holes in the vertical direction, and the tension spring is provided with a drag hook which is hooked in the hook holes.
In certain embodiments, the draw cord is a steel cord.
The utility model discloses following beneficial effect has: the utility model provides a counterweight device of a roller shutter door, which realizes the counterweight effect of the roller shutter door by connecting a pulley and a hook frame through a tension spring, the tension spring occupies small space and is arranged outside the roller shutter door, and the installation space of the roller shutter door is not occupied, therefore, the installation is convenient and safe; furthermore, the utility model provides a rolling slats door counter weight device installs in the side of the spool of rolling slats door, no matter be the axle drive or the fixed rolling slats door of axle all is suitable for, also need not to reserve unnecessary installation space in the reel to use, installation restriction have been avoided.
Drawings

fig. 2 is a partially enlarged view of a portion a in fig. 1.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings 1 and 2 in conjunction with the following embodiments.
The utility model provides a rolling slats door counter weight device, concrete technical scheme is as follows:
rolling slats door counter weight device, including reel 1, stay cord 2, pulley 3 and couple frame 4, 1 fixed cover of reel is established on the rolling slats door roll screen mechanism 5, one side of reel 1 is provided with leading wheel 6, leading wheel 6 sets up with 1 interval of reel, the one end winding of stay cord 2 is at reel 1, form traction end 21, the other end of stay cord 2 is in proper order around adorning leading wheel 6 and pulley 3 and fixed setting, form stiff end 22, stiff end 22 is located the top of couple frame 4, pulley 3 is located between reel and the stiff end 22, 4 fixed mounting of couple frame are in bottom one side of rolling slats door, pulley 3 is connected with couple frame 4 through one or more extension spring 7. When the door curtain is pulled by hand to close the door, the rolling curtain mechanism 5 drives the tension spring 7 to deform and stretch through the steel wire rope, the tension force is increased, but the drooping part of the door curtain is also lengthened, the dead weight of the door curtain is increased, the two parts are in a balanced state, and the gravitational potential energy of the door curtain is converted into the elastic potential energy of the tension spring 7; when the door curtain is pushed by hand to open the door, the door curtain rises, the self weight of the door curtain is reduced, at the moment, the rolling mechanism 5 drives the tension spring 7 to recover and contract, the tension force of the tension spring is reduced, the door curtain and the tension spring are still in a balanced state, and the elastic potential energy of the tension spring 7 is converted into the gravitational potential energy of the door curtain; the door curtain can easily slide up and down under the assistance of the tension spring 7 to realize manual door opening and closing, and the manual rolling door opening and closing can be operated outdoors.
In some embodiments, the reel 1 is tower-shaped or cylindrical. The tower-shaped reel 1 has the advantages that the diameter of the reel is changed to change the torque, so that the overlarge tension change of the tension spring is compensated; the cylindrical wire wheel 1 has the advantage that the tension of the tension spring varies over a moment arm of the same diameter, thus maintaining the synchronization between the moment and the tension.
In some embodiments, the hook frame 4 is provided with a plurality of hook holes 41 uniformly in the vertical direction, and the tension spring 7 is provided with a drag hook 71, and the drag hook 71 is hooked in the hook holes 41. In this way, the hook 71 can be used with different hook holes 41 to accommodate different rolling doors.
In certain embodiments, the pull cord 2 is a steel cord. The steel wire rope is firm and can bear the weight of the rolling door.
To sum up, the utility model provides an implementation mode of rolling slats door counter weight device general goes into down:
a winding wheel 1 is arranged on one side of a scroll (a shaft-driven roller shutter door) or a winding drum (a shaft-fixed roller shutter door) of the roller shutter door, and one end of a steel wire rope is fixed on the winding wheel 1 and is wound in order; the reel 1 has a wire groove in which the wire rope must be wound in order to change the torque, resulting in unstable tension. The other end of the steel wire wheel is wound on the guide wheel 6 and fixed on a wall or a bracket, a pulley 3 is arranged on the steel wire rope wound around the guide wheel 6, a tension spring 7 is arranged on the pulley 3, and the other end of the tension spring 7 is hooked on a hook hole 41 at a proper position according to the weight of the roller shutter door. The utility model discloses simple to operate, safe no matter be that the axle drives or the fixed rolling slats door of axle all is suitable for, also need not to reserve unnecessary installation space in the reel to use, installation restriction have been avoided.
The above-mentioned only the utility model discloses the feasible embodiment of preferred is not right the utility model discloses a restriction, the utility model discloses also not be limited to the above-mentioned example, technical field's technical personnel the utility model discloses an in the essential scope, change, modification, interpolation or replacement made also should belong to the utility model discloses a protection scope.
