T-shaped rail integrated tensioning device

Abstract

The invention discloses a T-shaped rail integrated tensioning device, and aims at providing a T-shaped rail integrated tensioning device which has the beneficial effects of being simple in structure,low in cost and capable of achieving the functions of chain connecting, tensioning and engagement and disengagement at the same time. According to the technical scheme, the T-shaped rail integrated tensioning device is characterized in that chain connecting rods are connected through a fixed mechanism; the fixed mechanism comprises a eudipleural conic connecting seat; connecting grooves used for being connected with a clutch spring bolt are formed in the conic connecting seat; connecting holes are further formed in the two ends of the conic connecting seat; the chain connecting rods are connected in the connecting holes in a sliding manner; and the position is adjusted and fixed through adjustable connecting parts arranged on the chain connecting rods and the conic connecting seat. The T-shaped rail integrated tensioning device is quite simple in structure and quite low in manufacturing and using cost; the tensioning device and a clutch can be combined together, and the tensioning device can have the functions of chain connecting, tensioning and engagement and disengagement at the same time; and the service life of the tensioning device is longer, overall wear resistance is higher,and adjustment of operation personnel is more convenient.

Description

technical field [0001] The invention relates to the field of metal rolling door accessories, in particular to a T-shaped track integrated tensioning device. Background technique [0002] The rolling shutter door is made of multi-joint movable door pieces connected in series. In the fixed slideway, the upper and lower doors are rotated around the reel above the door. The door leaf of the rolling shutter door is made of metal blades connected to each other. A rotating shaft is set above the door opening, and the opening and closing of the blades are controlled by the rotation of the rotating shaft. The rolling shutter door is suitable for the doors of shops, warehouses, garages or other relatively tall openings, including rolling shutter panels, guide rails and transmission devices. [0003] There are mainly two forms of shutter panels: sheet type and empty format, among which sheet type is used more. The leaf (also known as brake) type curtain plate is rolled from aluminum ...

AI Technical Summary

Problems solved by technology

[0007] Although this kind of mechanical chain tensioner with compliant leaf spring can remove the excessive tension on the tight side of the chain and ensure the necessary tension on the loose side of the chain, on the one hand, the structure of this tensioner is relatively complicated, The production cost is high. On the other hand, since the T-shaped track needs to be connected with the clutch during use, the use of this tensioner will make the connection between the T-shaped track and the clutch more difficult.
