Description

Technical Field

[0001] The utility model relates to the technical field of door leaf detection, in particular to a device for measuring the opening and closing force of a steel door. Background Art

[0002] Doors and windows usually need to undergo eight tests, namely material testing, wind resistance, airtightness, thermal insulation, sound insulation, lighting performance, repeated opening and closing performance, and opening and closing force testing. The opening and closing force requirement for doors and windows is no more than 50N. For the current door leaf opening and closing force measurement, an opening and closing force measuring device is required. However, the current opening and closing force measuring device cannot fix door leaves of different widths during testing, and is not very practical. In addition, the current opening and closing force measuring device mostly uses manual rotation of the door panel to determine the opening and closing force by observing the opening and closing force detector body. However, manual rotation of the door panel is not conducive to fixing the dynamometer, and it is difficult to ensure the detection accuracy.

[0003] For example, a simple door opening and closing force measuring device with publication number CN212158900U comprises a bottom plate, a fixing frame provided on the top plate of the bottom plate, a screw hole provided on the side wall of the fixing frame, an extrusion device connected to the screw hole through a thread, the extrusion device comprising a push plate, a screw provided on the surface of the push plate for rotation, the outer wall of the screw fitting with the inner thread of the screw hole, a top plate provided on the top of the fixing frame, a rotating plate provided for rotation between the top plate and the bottom plate near the edge, a pull ring provided on the surface of the rotating plate, an opening and closing force detector body hingedly provided inside the pull ring, the screw is rotated by the utility model, so that the outer wall of the screw slides back and forth along the thread of the inner wall of the screw hole, thereby driving the push plate to move back and forth, and the push plate can squeeze and fix door leaves of different widths inside the door opening, which is more practical, and rotating the rotating plate drives the opening and closing force detector body to rotate and measure the opening and closing force, saving labor intensity and ensuring stability.

[0004] The above technical solution has some problems in practical application. In practical application, it cannot realize the quick installation between the detection device and the door body, and cannot realize the detection in both directions of the door body opening and closing, which is not conducive to the detection work. Therefore, it is necessary to invent a device for measuring the opening and closing force of steel doors to solve the above problems. Utility Model Content
