Closing-up ribbon, tightening device for tightening closing-up ribbon and ribbon kit with tightening device

Abstract

The invention discloses a closing-up ribbon, a tightening device for tightening the closing-up ribbon and a ribbon kit with the tightening device. The closing-up ribbon comprises a ribbon body and a lock head, wherein the ribbon body is of a strip-shaped banded structure, and a clamping tooth area extending in the length direction of the ribbon body is arranged at one end of the ribbon body. The lock head is fixed to the end, away from the clamping tooth area, of the ribbon body. A lock buckle is arranged in the lock head, and according to the matching relation of the lock buckle and the clamping tooth area, the lock buckle can be in a locking or unlocking state. In the locking state, the clamping tooth area can pass through the lock head only in the single direction of the bundling port tightening direction, and in the unlocking state, the clamping tooth area can pass through the lock head in the two directions. The tightening device is used for applying force to the closing-up ribbonso that the ribbon can be pressurized and tightened. During usage, the closing-up ribbon is tightly bundled manually, then, the tightening device is used for pressurizing and tightening the closing-up ribbon, the closing-up ribbon can achieve the strong enough tight bundling degree, and the phenomenon that gaps exist in the bundling port position, and consequently dust leakage is caused can be avoided.

Description

technical field [0001] The present invention relates to the technical field of fasteners, in particular to a belt-shaped closing fastener. Background technique [0002] Hoop (or tie) is a commonly used fastener and is used in many fields. At the connection of the powder scale cloth bag of the concrete batching plant, the cloth bag is usually tied with a hoop, such as figure 1 As shown in the figure, the adopted hoop is composed of two semi-circular steel belts, and the lugs at both ends of the steel belts are connected by bolts to tie the bag mouth of the cloth bag tightly to the discharge port of the powder scale. [0003] However, it is not only time-consuming and laborious to use the semi-circular structure hoop that is pressed and fixed by bolts for bundling, but also there will be a gap at the bolt connection, so that the cloth bag cannot be in close contact with the feeding port, which is likely to cause dust leakage. SUMMARY OF THE INVENTION [0004] In view of th...
