In the present embodiment, in order to better explain the position limit protection device, first, it is necessary to give a preliminary explanation of the structure of the electric laundry rack.

Generally, an electric laundry rack includes a rack body installed on a wall body and a laundry rack connected to the rack body through a traction rope, and a driving motor for driving the traction rope is installed on the rack body, and is activated by receiving a signal from a control module through connection with the control module.

As shown in fig. 1 to 2, the utility model provides a limiting protection device of an electric clothes hanger, which comprises a limiting switch 1 mounted on a hanger body and buffer mechanisms 2 mounted at two ends of the clothes hanger, wherein the buffer mechanisms 2 and the clothes hanger are connected through a buckling mechanism 3.

Wherein:

buffer gear 2 includes through fixed mounting the buffer board 202 that telescopic link 201 on the support body is connected telescopic link 201 outside cover is equipped with both ends and fixes respectively the support body with buffer spring 203 on the buffer board 202, buffer spring 203 its inner diameter when original length with telescopic link 201 is the same.

The telescopic rod 201 in this embodiment is not limited to a specific telescopic manner, and may be a telescopic rod having a conventional inner cylinder and outer cylinder structure, or a telescopic rod having elasticity, that is, only a structure having a telescopic function is required, and the telescopic rod 201 is arranged to play a role of guiding when the laundry rack reaches the top.

Meanwhile, the impact which may be generated directly between the clothes hanger and the hanger body is relieved through self expansion and contraction and the buffer action of the buffer spring 203 and the like, so that the damage caused by mutual collision between the devices is reduced.

In general, no matter where the clothes hanger is located, the whole weight of the clothes hanger is borne by the traction rope, and the traction rope needs to bear the functions of traction and stretching, so that the clothes hanger is often installed on a hanger body through a fixed pulley and the like.

Therefore, in the present embodiment, when the laundry rack is raised to the high position, the laundry rack is fastened by the fastening mechanism, so that the fastening mechanism bears the mass of the laundry rack, the acting force on the traction rope is reduced, and the service life of the device is prolonged.

Specifically, the method comprises the following steps:

When the driving motor tightens the traction rope to enable the height of the clothes hanger to rise, the clothes hanger is gradually close to the hanger body, when the height of the clothes hanger reaches the buffer plate 202, the whole buffer plate will drive all the structures on the buffer plate to rise together due to the acting force of the traction rope, when the electromagnet on the buffer board touches the limit switch, the limit switch will send a stop signal to the control module, the control module will cut off the power supply of the driving motor and the electromagnet after receiving the stop signal, therefore, the height of the clothes hanger stops rising, the electromagnet does not have electric power due to power failure, the buckling plate 303 resets under the action of the torsion spring to enable the hook 305 at the end of the buckling plate to be meshed with the clamping groove 4, the clothes hanger is connected with the buckling mechanism through the meshing of the hook 305 and the clamping groove 4, the mass of the clothes hanger is transmitted to the buckling mechanism, and acting force on a traction rope is reduced.

When the clothes hanger needs to be put down, the driving motor is started to rotate reversely only through the control module, at the moment, the electromagnet is electrified again, the clamping plate is pulled again to move, so that the clamping hook and the clamping groove are separated, and the traction rope is released in the reverse rotation of the driving motor to put down the clothes hanger.

It should be noted that the absorbing sheet 304 is made of a metal material capable of being absorbed by a magnet, and is preferably provided as an integrally cast steel casting, which not only has excellent magnetic absorption capability, but also has high structural strength, and shows more durable service time.

Therefore, through setting up buffer gear 2 in this real-time mode, can convert the rigidity collision between clothes hanger and the support body and the elastic potential energy of pressure spring into, play the cushioning effect, avoid the produced kinetic energy of rigidity collision to influence the pulling force of haulage rope 5, buffer gear 2 limited buffer distance plays limiting displacement to clothes hanger 1 simultaneously.
