Problems solved by technology
[0003] Although the door closing resistance can be adjusted to less than 150N, in fact, the instantaneous force of the door panel hitting a hard object is much greater than 150N, which is very likely to cause damage to the bones of children and infants, posing a great safety hazard

Embodiment Construction
[0018] The present invention will be described in further detail below in conjunction with the embodiments in the accompanying drawings, but this does not constitute any limitation to the present invention.
[0019] see Figure 1 to Figure 4 As shown, the present invention provides a technical solution: a device for adjusting the resistance of the door when closing the door, including a door panel 1, a slide plate 14, a motor 7, a controller 6 and a fixed frame 15, and the fixed frame 15 is provided with a controller 6. A driven wheel 3 and a driving wheel 8 are horizontally arranged on the front of the fixed frame 15; a motor 7 electrically connected to the controller 6 is connected to the driving wheel 8, and a pair of wire pulleys 2 are also arranged on the front of the fixed frame 15, located on the driven wheel 3 and below the driving pulley 8; the driving pulley 8 is connected with the driven pulley 3 through the belt 5; the pair of wire pulleys 2 are connected through t...

The invention provides a device for adjusting resistance in door closing of a door machine. The device comprises door sheets, slide plates, a motor, a controller and a fixed frame; the controller is arranged on the fixed frame; a driven wheel and a driving wheel are horizontally arranged on the frontal surface of the fixed frame; the driving wheel is connected with the motor electrically connected with the controller; a pair of steel wire pulleys is arranged on the frontal surface of the fixed frame, and is positioned below the driven wheel and the driving wheel; the driving wheel is connected with the driven wheel through a belt; the pair of steel wire pulleys are connected through a linkage steel wire rope; a pair of slide plates is arranged on the linkage steel wire rope; the door sheets are respectively fixed below the pair of slide plates; a door knife device is arranged on the slide plate on the left side; and in-place leaning balls are respectively arranged on the pair of slide plates, and are arranged oppositely. The device is simple in structural design; and when a foreign object is between the door sheets for blockage, after the stress of a spring on the door knife device exceeds initial force, the spring acts to achieve an excellent energy sucking effect, so that the crushing of persons in failure of an optical curtain is prevented, and the personal safety can be effectively protected.
Description
technical field [0001] The invention belongs to the technical field of car elevators, and in particular relates to a device for adjusting the resistance encountered by a door closing door. Background technique [0002] The light curtain is a safety protection device installed on the door panel of the door operator. When the receiving and emitting tube of the light curtain detects the entry and exit of people, the light curtain relay acts and feeds back to the elevator main control, which sends a door opening signal to the door operator controller. To achieve the purpose of preventing pinching. After the elevator is installed and debugged, before it is officially put into use, the Technical Supervision Bureau has an acceptance process. For one item of the door operator, the resistance to closing the door needs to be less than 150N, so as to prevent people from being trapped and injured when the light curtain fails. [0003] Although the door closing resistance can be adjust...
