Problems solved by technology

In addition, due to the existence of frictional force and the inclination of the counterweight's movement track is limited by being set inside the cover plate, during the opening or closing process, the counterweight is likely to be in a certain position due to the division of the frictional force. Insufficient force and stuck somewhere to stop rolling, causing unnecessary trouble

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] A device 20 for adjusting the gravity-moment curve characteristic of the cover plate of the hanging object hole is arranged on the cover plate 10 of the hanging object hole. The cover plate 10 has a hinged end 12 connected to the frame of the hanging object hole, and a free end 11 opposite to the hinged end 12 .

[0033] The device 20 for adjusting the gravity-moment curve characteristic of the cover plate of the hanging object hole includes a counterweight 3 , an elastic device 6 , and a slide rail 4 . The slide rail 4 is arranged along the radial direction of the cover plate 10 , and the counterweight 3 and the elastic device 6 move along the slide rail 4 between the free end 11 and the hinged end 12 of the cover plate 10 .

[0034] The slide rail 4 is installed on the cover plate 10 through the bracket 9 , thereby being fixed on the cover plate 10 ...

Abstract

The invention discloses a device for adjusting a curve characteristic of gravitational of a cover plate of a hanging hole of a torsional spring structure. The device is arranged on the cover plate of the hanging hole and comprises a counter weight, an elastic device and a pulley, and the counter weight and the elastic device move between a free end and a hinge end of the cover plate along the pulley. The device is simple in structure and convenient to implement, the problem that the cover plate of the hanging hole turns up is solved, and opening and closing of the cover plate of the hanging hole are facilitated.

Description

technical field [0001] The invention relates to an object-hanging hole used in a multi-storey building, in particular to a device for adjusting the gravity-moment curve characteristic of the cover plate of the hanging object hole. Background technique [0002] In high-rise buildings and factory buildings, most of them are equipped with openings or openings for moving in or moving out equipment, that is, hanging holes. The hanging hole usually consists of a frame and a movable cover installed on the frame. The current movable cover, especially the folding cover, often has a warped head due to the torsion spring and other power-assisted opening devices, that is, when the cover is closed, it cannot maintain a horizontal position in a natural state and will automatically open an angle such as figure 1 shown. In addition, when the cover plate is from the open state to the horizontal state, there is a defect that the starting torque is insufficient. [0003] Chinese patent 201...
