Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, the present invention provides the following technical solutions: the utility model provides a rolling slats door curtain bottom overspeed device tensioner, includes door frame 1, reel 2, motor 3, door curtain 4, spout 5 and tensioning stop device 6, and 2 upper ends at door frame 1 are connected in the rotation of reel, and motor 3 fixed mounting is in the one end of reel 2, and 4 covers of door curtain are established at 2 surfaces of reel, and spout 5 is seted up in the inside of door frame 1, and 6 fixed mounting of tensioning stop device are in the inside of door frame 1.

Tensioning stop device 6 includes slider 601, and one side of slider 601 rotates and is connected with fixed pulley 602, and the surface cover of fixed pulley 602 is equipped with belt 603, and the inside fixed mounting of door frame 1 has take-up pulley 604, and door frame 1 is inside to be close to lower extreme position fixed mounting and has belt pulley 605.

In this embodiment, when the door curtain 4 is hit by strong wind, since the slider 601 connected to the door curtain 4 is installed on the sliding groove 5, in addition, the fixed pulley 602 is limited by the belt 603, the belt 603 is tensioned by the tension pulley 604, one end of the belt 603 is fixed on the belt pulley 605, so that the sliding block 601 is under the tension of the belt 603, so as not to slip off from the sliding groove 5 under the action of force, ensure the door curtain 4 to be stable in the door frame 1, when the door curtain 4 moves up and down, the sliding block 601 is driven to move up and down in the sliding groove 5, and the vertical up-and-down movement is kept under the matching of the fixed pulley 602, the belt 603, the tension pulley 604 and the belt pulley 605, so that the shaking condition is avoided, the condition that the door curtain 4 is blown out from the door frame 1 under the action of strong wind is avoided, the stability of the door curtain 4 in the door frame 1 is improved, and the condition that the roller shutter door is damaged under the action of strong wind is avoided.

Specifically, the fixed pulley 602, the tension pulley 604 and the pulley 605 are connected by a belt 603.

In this embodiment, a belt 603 connects a fixed pulley 602, a tension pulley 604, and a pulley 605, and the belt 603 transmits tension to the slider 601.
