The falling protection device of the clothes hanger 3 comprises a first limiting part 6, a triggering component and a driving component 9.

As shown in fig. 4 and 5, the first limiting portion 6 is provided at one end of the folding frame 2 connected to the body 1, and is configured to move in a predetermined direction when the folding frame 2 is unfolded. The first limiting portion 6 is disposed on the sliding portion 4 so as to slide along with the sliding of the sliding portion 4, in this embodiment, the predetermined direction is the extending direction of the sliding rail 5, and in other embodiments, the predetermined direction may be other directions, as long as the predetermined direction is perpendicular to the unfolding direction of the folding frame 2, because the folding frame 2 stretches and contracts according to the parallelogram principle. In the present embodiment, the first limiting portion 6 is a tooth portion and is formed by a gear fixedly connected to the sliding portion 4, and in other embodiments, the first limiting portion 6 may be formed by a rack fixedly connected to the sliding portion 4.

The trigger assembly is in a first state under the pressure of the steel wire rope and is switched to a second state when the steel wire rope breaks. In this embodiment, the trigger assembly includes a sensor switch for sensing whether the wire rope is broken or not, and a controller for use as will be described below. In this embodiment, the inductive switch is a micro switch, and the inductive switch is in a first state when the trigger component is in a first state, and the inductive switch is in a second state when the trigger component is in a second state, where the first state is a state when the wire rope is not broken, and the second state is a state when the wire rope is broken. In other embodiments, the inductive switch may also be a photoelectric switch.

The driving assembly 9 includes a second limiting portion 8 supported on the machine body 1, and the second limiting portion 8 is configured to move onto the moving path of the first limiting portion 6 in response to the triggering assembly being switched from the first state to the second state, so as to prevent the first limiting portion 6 from continuing to move towards the predetermined direction, so as to prevent the unfolding action of the folding frame 2. In this embodiment, the second limiting portion 8 is a tooth portion and is adapted to be engaged with the first limiting portion 6, the driving assembly 9 includes a limiting member 7, a driving member 12 and a pushing member 13, the limiting member 7 is slidably connected to the machine body 1 along a direction perpendicular to the predetermined direction, the second limiting portion 8 is formed by the limiting member 7, and a length of a portion of the second limiting portion 8 is greater than or equal to a stroke of the first limiting portion 6.

The working principle of the falling protection device of the clothes hanger 3 is as follows:

as shown in fig. 6, when the wire rope is not broken, the limiting member 7 makes the second limiting portion 8 not located on the moving path of the first limiting portion 6 under the action of gravity. When the steel wire rope is broken, the inductive switch sends a breaking signal to the controller, the controller controls the driving piece 12 to drive the pushing piece 13 when receiving the breaking signal, the pushing piece 13 pushes the limiting piece 7 to slide so as to enable the second limiting portion 8 to be meshed with the first limiting portion 6, at this time, the state is as shown in fig. 4 and 5, and as the supporting portion 10 can form a stress point, the sliding portion 4 can not slide and then the folding frame 2 is prevented from being unfolded continuously, so that the clothes hanger 3 is prevented from being directly dropped under the action of gravity.

Because the first limiting part 6 is arranged to move towards the preset direction when the folding frame 2 is unfolded, and the second limiting part 8 is supported on the machine body 1, when the steel wire rope is broken, the second limiting part 8 can move to the moving path of the first limiting part 6, so that the first limiting part 6 is prevented from continuing to move towards the preset direction, and then the folding frame 2 is prevented from being unfolded, and the clothes hanger 3 is prevented from falling down directly under the action of gravity. In addition, the length of the part of the limiting piece 7 forming the second limiting part 8 is larger than or equal to the stroke of the first limiting part 6, so that the direct falling of the clothes hanger 3 can be prevented in time when the steel wire rope is broken no matter where the clothes hanger 3 is located before the steel wire rope is broken.
