Abstract
The invention discloses an automatic door overload protecting element. The automatic door overload protecting element comprises an element body, a mounting hole is formed in the center of the element body, a plurality of inner teeth meshed with outer teeth of a transmission shaft are arranged at the inner side of the mounting hole, an opening is formed in one side of the mounting hole, two closed ends are arranged at the position of the opening, screw holes are formed in the closed ends, and the closed ends close the opening through a screw. A boss is arranged on the upper surface of the other end of the element body, and notches are formed in the two sides of the element body under the boss. According to the open or close principle of the automatic door, when a motor is started, the torque is transmitted to a rotating shaft which is meshed with the 72 inner teeth of the part, the part can rotate along with the rotating shaft, and the torque is transmitted to a main shaft of the door through the boss portion of the part, so that the open or close of the door is achieved by tuning on or tuning off the motor; when the suffered resistance of the door reaches a certain degree during the open and close process, the torque acting on the part exceeds the bearing range of the part, and the part is cracked at the opening of the two sides, so that overload protection is achieved.
Description
Technical field
The present invention relates to a kind of automatic door technical field, particularly a kind of automatic door overload protection element.
Background technology
Automatic door understands the extension of the concept that be door theoretically, is the development and improvement that the function of door is carried out according to human needs.Automatic door developed very ripe, automatic door refers to: the control unit that people can be identified as enabling signal close to the action (or by certain introduction authorize) of door, by drive system, door is opened, again door is closed automatically after people leaves, and to the system that the process implementation opened and closed controls, during existing automatic door switch, the obstruction run into, easily damages the parts such as motor, gear.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of automatic door overload protection element.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of automatic door overload protection element; comprise component body; the centre of described component body is provided with a pilot hole; some internal tooths engaged with power transmission shaft external tooth are provided with inside described pilot hole; the side of described pilot hole is provided with opening; described opening part is provided with two closing ends; described closing end is provided with screw; by screw, opening is closed; the other end upper surface of described component body is provided with a boss, and the component body both sides below boss are provided with breach.
As a further improvement on the present invention, 72 internal tooths are provided with in described pilot hole.
As a further improvement on the present invention, described component body is made by extrusion process is one-body molded.
The invention has the beneficial effects as follows: automatic door of the present invention is opened or closed principle: after actuating motor, torque axis is handed on the turning cylinder engaged with this part 72 internal tooths, this part rotates with turning cylinder, by the projection section of this part, torque axis is handed on the main shaft of door again, thus realizes unlatching or the closedown of door by switching motor; When door is at switch, after the resistance run into acquires a certain degree, the moment of torsion acting on this part just exceedes its tolerance range, causes this part in the fracture of both-side opening place, thus realizes overload protection.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Indicate in figure: 1-component body; 2-pilot hole; 3-internal tooth; 4-opening; 5-closing end; 6-screw; 7-boss; 8-breach.
Detailed description of the invention
