Description
Technical Field
The utility model relates to a hanger, in particular to a hanger on a tensioning adjusting end of a linkage door transmission belt.
Background
The common synchronous and equidirectional linkage doors are mainly of a double-door or triple-door linkage type, and a pair of guide wheels and a driving belt (usually a belt, a steel wire rope or a steel wire belt) wound on the pair of guide wheels are arranged on two sides of the upper end of one driving door of two adjacent linkage doors. The pulley is manually adjusted to tension the belt due to the need to tension the belt during initial installation of the linked door and the possibility of belt slack during subsequent frequent use. Because one of this pair of guide pulley is the tight pulley, another is the regulating wheel of adjustable elasticity, synchronous syntropy gang door on the current market only adjusts the drive belt elasticity for adjusting the adjusting screw on the regulating wheel, however owing to lack the mechanism of fixed locking, lead to the drive belt can have the phenomenon of taking place to become flexible in the use, thereby influence performance, at this moment, need artificially go to tighten adjusting screw, otherwise the drive belt can have the risk that drops, so current synchronous syntropy gang door needs maintainer often to go to adjust the drive belt, and at this moment, often need pull down the door leaf and just can adjust, lead to adjusting troublesome.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide the tensioning and locking hanger of the linkage door transmission belt with the locking mechanism, which has a more reasonable structure and is more convenient to adjust.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the utility model provides a tensioning locking pendant of linkage door drive belt establishes on the initiative door leaf of two adjacent synchronous syntropy linkage door leaves, including the pendant main part, adjusts the seat, the tight regulation screw, the shaft, the take-up pulley, take-up pulley locking screw to and the drive belt, wherein:
the hanging part main body comprises a body positioned at the upper end of the door leaf and an extending arm which is laterally exposed out of the door leaf; a hanging screw hole is vertically arranged on the body; a locking screw moving groove and a clamping seat screw hole which can be used for the locking screw of the tensioning wheel to slide are vertically arranged on the extending arm, and an adjusting sliding groove is transversely arranged;
the adjusting seat comprises a wheel seat which can be slidably inserted into the adjusting sliding groove and an adjusting screw seat which is positioned at the outer end of the wheel seat; the adjusting screw seat is opposite to the end face of the body, and an adjusting screw hole is formed in the adjusting screw seat;

the upper end of the wheel shaft is connected with the tensioning wheel, and the lower end of the wheel shaft is fixed on the wheel seat; a locking screw hole for screwing the locking screw of the tension wheel is formed in the upper part of the wheel shaft;
the tensioning wheel locking screw penetrates through the locking screw moving groove of the extending arm and then is screwed into the locking screw hole of the wheel shaft;
the transmission belt is wound on the tension wheel.
In the improved scheme of the tension locking hanging piece of the linkage door transmission belt, the lower end of the extension arm is provided with an outer cover capable of covering the tension wheel locking screw and the tightness adjusting screw.
In an improved scheme of the tension locking hanging piece of the linkage door transmission belt, the outer cover is hooked on the extending arm in a sliding buckle mode.
Compared with the prior art, the utility model has the beneficial effects that: when the tensioning adjusting end hanger is installed on the door leaf for use, the screw head of the tensioning wheel locking screw faces downwards vertically, and the screw head of the elastic adjusting screw is exposed out of the wheel seat transversely; in addition, the tensioning wheel locking screw is arranged as a locking mechanism to ensure that the transmission belt cannot be loosened during long-term use, so that the maintenance frequency is greatly reduced, even if the transmission belt is loosened at the later stage due to the fact that the locking screw is possibly locked insufficiently during installation, a door leaf does not need to be detached, a worker can transversely screw the loosening adjusting screw by only lifting up to loosen the tensioning wheel locking screw, and at the moment, the inner end of the loosening adjusting screw is propped against the outer end face of the adjusting screw seat, so that the adjusting seat can be transversely pulled outwards along the adjusting sliding groove of the body, and the tensioning wheel is driven to move outwards to tighten the transmission belt; finally, the tightening wheel locking screw is tightened, so that the tightness adjustment of the transmission belt on the hanging piece at the tensioning adjustment end is completed.
