Mechanism for testing opening and closing of door

Abstract

The invention discloses a mechanism for testing the opening and closing of a door. The mechanism comprises a frame. The frame is fixedly provided with an opening and closing mechanism rack. One end ofthe opening and closing mechanism rack is fixedly hinged to a swing rod. The lower end of the swing rod is hinged to the driving end of a cylinder. The cylinder is installed on the opening and closing mechanism rack. The upper end of the swing rod is fixedly connected to one end of an industrial cotton tape. The other end of the industrial cotton tape is fixedly connected to a sucker. The suckeris attached to a door body. The central section of the swing rod is movably hinged to a polyurethane pulley mechanism. Through the extension of the cylinder, the swing rod swings towards the door body. Under the effect of a torsional spring, a polyurethane pulley is contacted with the surface of the door body. Under the effect of the swing rod, a pressing rod makes the polyurethane pulley roll onthe door body so as to drive the door body to be closed. When the cylinder is retracted, the swing rod is driven to swing away from the door body so that the industrial cotton tape drives the sucker to move simultaneously. The sucker is fixed to the door body so that the door body is opened.

Description

technical field [0001] The invention relates to the field of testing, in particular to a mechanism for testing the opening and closing of doors. Background technique [0002] At present, the mechanism for testing the opening and closing of the door used by electrical manufacturers is usually a servo motor connected to a planetary reducer, which drives the pendulum to move within a certain angle range at a low speed. The servo motor needs to be controlled and driven by the controller and the driver, and a DC power supply of the corresponding voltage should be configured for the controller and the driver. This kind of mechanism can usually complete the action of opening and closing the door very well, but the cost of this mechanism is slightly high and the software programming is relatively cumbersome, and it is not easy to use. When counting the number of door opening and closing, it is necessary to add an additional counting auxiliary device, which adds cost and complexity ...

Problems solved by technology

This kind of mechanism can usually complete the action of opening and closing the door very well, but the cost of this mechanism is slightly higher and the software programming is more cumbersome, and it is not easy to use

When counting the number of door opening and closing, it is necessary to add an additional counting auxiliary device, which adds cost and cumbersomeness virtually

[0003] When the door is closed, the polyurethane block is used to push the door body. Since the polyurethane block and the swing rod are fixed, there is sliding friction between the door body and the polyurethane block, which will wear the surface of the door body in the long run. Therefore, we propose a test The door opening and closing mechanism is used to solve the above problems
