Description
Technical field
The utility model relates to overload protection field, particularly relates to automatic door overload protection arrangement.
Background technology
In automatic door operation, cannot automatically close if any foreign matter or because other reasons causes at closedown open position, and at the same time as signal transmitting apparatus goes wrong, then motor can not decommission, excessive moment of torsion can make motor be damaged, even fire.
Utility model content
For solving the problems of the technologies described above, the utility model provides automatic door overload protection arrangement.
The utility model solves the technical scheme that its technical problem adopts: the utility model comprises main body, described main body one end is provided with transmission boss, described main body and both sides, boss junction are respectively equipped with breaking groove, described body interior is provided with driving hole, described driving hole is provided with internal tooth, and the described main body other end is provided with adjustment hole, and described adjustment hole both sides are respectively equipped with contiguous block, described contiguous block is provided with connecting hole, is provided with connecting rod in described connecting hole.
The beneficial effects of the utility model: automatic door overload protection arrangement of the present utility model, connecting rod is unclamped, adjustment hole is made to become large, motor coupling portion is placed in driving hole, adjusting device position makes internal tooth be engaged completely with motor coupling portion, contiguous block is driven to draw close mutually by connecting rod after occlusion, protective device is made to be fixed on motor, driven by motor protective device rotates, protective device rotation makes transmission boss turning handle torque axis be handed on the main shaft of automatic door, automatic door action is made to open or close, occur if any abnormal conditions, automatic door cannot continue switch motion, and signal transmitting apparatus is not when working, the moment of torsion that motor produces exceedes protective device and can bear scope, breaking groove ruptures automatically, make transmission boss and body portion from, avoid damage that motor occurs due to the excessive overload of moment of torsion or cause fire etc.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein: 1-main body, 2-transmission boss, 3-breaking groove, 4-driving hole, 5-internal tooth, 6-adjustment hole, 7-contiguous block, 8-connecting hole, 9-connecting rod.
Detailed description of the invention
In order to deepen, to understanding of the present utility model, to be described in further detail the utility model below in conjunction with drawings and Examples, this embodiment, only for explaining the utility model, not forming protection domain of the present utility model and limiting.
As shown in Figure 1, described main body one end is provided with transmission boss, described main body and both sides, boss junction are respectively equipped with breaking groove, described body interior is provided with driving hole, described driving hole is provided with internal tooth, and the described main body other end is provided with adjustment hole, and described adjustment hole both sides are respectively equipped with contiguous block, described contiguous block is provided with connecting hole, is provided with connecting rod in described connecting hole.
The utility model automatic door overload protection arrangement concrete function is as follows: unclamped by connecting rod, adjustment hole is made to become large, motor coupling portion is placed in driving hole, adjusting device position makes internal tooth be engaged completely with motor coupling portion, contiguous block is driven to draw close mutually by connecting rod after occlusion, protective device is made to be fixed on motor, driven by motor protective device rotates, protective device rotation makes transmission boss turning handle torque axis be handed on the main shaft of automatic door, automatic door action is made to open or close, occur if any abnormal conditions, automatic door cannot continue switch motion, and signal transmitting apparatus is not when working, the moment of torsion that motor produces exceedes protective device and can bear scope, breaking groove ruptures automatically, make transmission boss and body portion from, avoid damage that motor occurs due to the excessive overload of moment of torsion or cause fire etc.
Above-described embodiment should not limit the utility model by any way, and the technical scheme that the mode that all employings are equal to replacement or equivalency transform obtains all drops in protection domain of the present utility model.
