It should be noted that: like reference numerals refer to like items in the following figures, and thus, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "disposed," "coupled," and the like are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The technical solution of the present invention is further specifically described below by way of specific embodiments and with reference to the accompanying drawings.

As shown in fig. 1 to 4, the limiting structure of the electric clothes drying machine comprises a movement base plate 1, a motor 2 and a winch 3, wherein an upper limiting microswitch 4 and a lower limiting microswitch 5 are arranged on the movement base plate 1, the motor 2 drives the winch 3 to rotate to generate displacement, when a clothes drying rod rises, the winch 3 moves for a certain displacement and then touches the upper limiting microswitch 4, the motor 2 stops operating, and the clothes drying machine reaches an upper limiting position; when the clothes airing rod descends, the winch moves for a certain displacement and then touches the lower limit microswitch 5, the motor 2 stops running, and the clothes airing machine reaches the lower limit.

The winch 3 is fixed on the machine core bottom plate 1 through the winch seat 6, winding threads are arranged on the surface of the winch 3, and a steel wire rope can be just contained in a thread groove between every two adjacent threads. The winch 3 is wound with a steel wire rope, one end of the steel wire rope is limited on the winch 3, and the other end of the steel wire rope is connected to the clothes airing rod. The steel wire rope is just arranged in the thread groove, and a winch pressing shaft 7 is arranged above the winch 3 and used for pressing the steel wire rope, so that the steel wire rope is prevented from being disordered.

The upper limit microswitch 4 and the lower limit microswitch 5 are fixed on the machine core bottom plate 1 through a mounting bracket 8. The upper limit microswitch 4 comprises an upper limit contact piece 41 and an upper limit contact 42, wherein the upper limit contact piece 41 is abutted against the upper limit contact 42 after being stressed and rotated so as to trigger the upper limit microswitch 4. The lower limit microswitch 5 comprises an upper limit contact piece 41 and a lower limit contact 52, and the lower limit contact piece 51 is pressed against the lower limit contact 52 after being stressed and rotated to trigger the lower limit microswitch 5. The upper limit microswitch 4 and the lower limit microswitch 5 are electrically connected with the motor 2.

The working principle is as follows: when the motor 2 starts to work, the motor 2 drives the winch 3 to rotate, and the rotation of the winch 3 enables the steel wire rope to be wound or loosened, so that the clothes airing rod is driven to ascend or descend. The winch 3 is displaced laterally due to its rotation. When the clothes airing machine ascends, the winch slowly moves leftwards for a certain distance and then touches the upper limit contact plate 41, the upper limit contact plate 41 is stressed to rotate and then collides with the upper limit contact 42 to trigger the upper limit microswitch 4, at the moment, the motor 2 stops rotating, and the clothes airing rod ascends to the highest position. When the clothes airing machine descends, the winch 3 moves slowly to the right, is positioned and moved and then is touched with the lower limiting contact piece 51, the lower limiting contact piece 51 is pressed against the lower limiting contact 52 after being rotated by force to trigger the lower limiting micro switch 5, the motor 2 stops rotating at the moment, and the clothes airing rod descends to the lowest position.

Therefore, the required length of the steel wire rope of the clothes airing machine can be calculated only by calculating the transverse displacement stroke of the winch 3 and combining the diameter of the steel wire rope wound on the winch 3 and the length of the steel wire rope reserved at the lower limit. The movement of the winch 3 generates displacement to touch the upper limit microswitch 4 or the lower limit microswitch 5 to control the upper limit and the lower limit of the clothes airing machine, the precision is high, and the clothes airing machine cannot be misaligned due to long-term use.

In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", and the like indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship which is usually placed when the utility model is used, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element to be referred must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
