[0048] Further, the shell 100 is also connected with a positioning rod 104, the positioning rod 104 is located in the slot 103 and is coaxially distributed with the rotating part 102; the gear cover 400 is also provided with a first avoiding hole 311 coaxially distributed with the first positioning ring 310; the cover body 410 is connected with a second positioning ring 440, the second positioning ring 440 is inserted into the first avoiding hole 311, the cover body 410 is also provided with a second avoiding hole in communication with the second positioning ring 440, the second avoiding hole is provided with a fastener, the fastener passes through the second avoiding hole, the second positioning ring 440, the first avoiding hole 311 and the first positioning ring 310 in sequence and is connected with the positioning rod 104, through the connection of the fastener and the positioning column, the displacement problem of the gear cover 400 and the stroke gear 300 in the direction of the respective rotation axes can be avoided.

[0049] The above fastener includes but is not limited to a bolt, and the connection mode of the fastener and the positioning column includes but is not limited to threaded connection.

[0050] Of course, in other embodiments, the stroke gear 300 is provided with an axle hole, and the rotating part 102 is rotatably inserted and matched with the axle hole.

[0052] Optionally, referring to Figure 2 and Figure 5 , the winding wheel 210 comprises a winding wheel body 211 and an outer gear ring 212 coaxially connected with the winding wheel body 211, and the output shaft of the motor 120 is engaged with the outer gear ring 212 through the gear 220 transmission assembly, so as to drive the outer gear ring 212 to rotate through the gear 220 transmission assembly, and then drive the winding wheel body 211 to rotate, and then use the winding wheel 210 to wind or release the connecting rope.

[0053] Further, the gear 220 is coaxially connected with the outer gear ring 212, that is, when the motor 120 drives the outer gear ring 212 to rotate, the gear 220 is synchronously driven to rotate, so as to drive the stroke gear 300 and the gear cover 400 to synchronously rotate through the gear 220, and when the protrusion 420 of the gear cover 400 abuts against the micro switch 110, the motor 120 is controlled to stop.

[0054] Still further, the winding wheel body 211 is provided with a winding groove (not shown in the figure), which is used for winding or releasing the connecting line.

[0055] In the related art, in order to enable the gear cover 400 to rotate relative to the stroke gear 300, and enable the relative position of the gear cover 400 and the stroke gear 300 to be locked after the gear cover 400 rotates relative to the stroke gear 300, so as to achieve the purpose of adjusting the angle that needs to be rotated when the protrusion 420 abuts against or separates from the micro switch 110, a clamping piece is arranged at the outer periphery of the cover body 410 of the gear cover 400, so as to engage the clamping piece with the outer gear ring 212 of the stroke gear 300; when it is necessary to adjust the position of the gear cover 400 relative to the stroke gear 300, the gear cover 400 is rotated relative to the stroke gear 300, and the clamping piece and the outer gear ring 212 are alternately engaged and separated, so as not to interfere with the adjustment of the gear cover 400; after adjustment, the relative position of the gear cover 400 and the stroke gear 300 can be relatively locked by engaging the clamping piece with the outer gear ring 212. However, the inventors have found that the clamping piece of this structure is unstable, and the clamping effect is not reliable, which cannot stably clamp the stroke gear 300, and is easy to be damaged, resulting in clamping failure, and further resulting in failure of the stroke adjustment mechanism.

[0056] In order to improve the above-mentioned problems, please refer to Figure 4 and Figure 5The gear cover 400 of the embodiment further comprises a clamping arm 430, the stroke gear 300 is provided with a first gear ring 301 and a second gear ring 302, the winding gear 200 is engaged with the first gear ring 301, and specifically, the gear 220 is engaged with the first gear ring 301; the cover body 410 is provided with an assembly hole 411, the clamping arm 430 is connected with the cover body 410 and located in the assembly hole 411; the cover body 410 is coaxially arranged with the stroke gear 300, and the clamping arm 430 is engaged with the second gear ring 302, the winding gear 200 can drive the stroke gear 300 to rotate, so as to drive the cover body 410 to rotate through the stroke gear 300, and the protrusion 420 can rotate with the cover body 410 and abut against or separate from the micro switch 110. When the relative position of the gear cover 400 and the stroke gear 300 is adjusted, the gear cover 400 is rotated relative to the stroke gear 300, and the clamping arm 430 can be alternately engaged with and separated from the second gear ring 302; when the gear cover 400 is no longer rotated relative to the stroke gear 300, the clamping arm 430 is stably engaged with the second gear ring 302.

[0057] The clamping arm 430 is located in the assembly hole 411 of the cover body 410, which can improve the connection stability between the clamping arm 430 and the cover body 410, and further improve the stability and strength of the cover body 410 clamped with the stroke gear 300 through the clamping arm 430. Moreover, the problem that the clamping arm 430 is easily damaged and fails can be solved by arranging the clamping arm 430 in the assembly hole 411, and further, the problem that the stroke adjustment mechanism 010 of the clothes drying machine fails due to the internal structure can be solved.

[0058] Further, the stroke gear 300 is provided with a first gear ring hole 304 and a second gear ring hole 305, the first gear ring 301 is arranged on the hole wall of the first gear ring hole 304, and the second gear ring 302 is arranged on the hole wall of the second gear ring hole 305, that is, the first gear ring 301 and the second gear ring 302 are both inner gear rings, and the first positioning ring 310 is located in the first gear ring hole 304; the gear 220 of the winding gear 200 extends into the first gear ring hole 304 and is engaged with the first gear ring 301; the cover body 410 of the gear cover 400 is provided with a containing space 413, part of the stroke gear 300 is embedded in the containing space 413, and the clamping arm 430 extends into the second gear ring hole 305 and is engaged with the second gear ring 302.

[0059] It should be understood that in other embodiments, at least the first gear ring 301 can also be an outer gear ring, which is not specifically limited here.

[0060] Optionally, the transmission ratio of the gear 220 to the first gear ring 301 is 1:(10-15), for example, 1:10, 1:12, 1:13, 1:15, etc., which is not specifically limited here.

[0061] Optionally, please refer to Figure 4 and Figure 5The clamping arm 430 comprises an arm body 431 and a ratchet 432 connected to the arm body 431, the arm body 431 is connected to the cover body 410 and located in the assembly hole 411, and the ratchet 432 is engaged with the second gear ring 302. Through the arrangement of the ratchet 432, the gear cover 400 can only rotate relative to the travel switch in one direction; in this way, the travel adjustment operability of the travel adjustment mechanism 010 of the clothes drying machine can be improved, which is beneficial to improve the assembly efficiency of the clothes drying machine; and when the protrusion 420 is in abutment with the spring sheet of the micro switch 110, the ratchet 432 can also prevent the gear cover 400 from rotating relative to the travel gear 300 under the action of the reaction force (≥2N) of the spring sheet, thereby ensuring the stability between the gear cover 400 and the travel gear 300.

[0062] Of course, in other embodiments, the clamping teeth of the second gear ring 302 can also be arranged as the ratchet 432; in this way, the gear cover 400 can also only rotate relative to the travel switch in one direction.

[0063] The number of the assembly holes 411 provided by the clamping arm 430 and the cover body 410 can be selected as needed.

In this way, after the gear cover 400 rotates relative to the travel gear 300, the stability of the relative position of the fixed gear cover 400 and the travel gear 300 can be improved.

[0064] In the embodiment, the gear cover 400 comprises four clamping arms 430, and the cover body 410 is provided with four assembly holes 411, and the four clamping arms 430 and the four assembly holes 411 are arranged one by one.

[0065] In other embodiments, the number of the clamping arms 430 and the assembly holes 411 can also be one, three, six, etc., which is not limited here.

[0066] Optionally, the arm body 431 of the clamping arm 430 and the assembly hole 411 are both arc-shaped around the rotation axis of the cover body 410.

[0067] Of course, in other embodiments, the arm body 431 of the clamping arm 430 and the assembly hole 411 can also be linear or other shapes, which is not limited here.

In this way, the reliability of the engagement between the ratchet teeth 432 and the second ring gear 302 can be ensured, and the caliber of the assembly hole 411 can be reduced except for the clearance groove 414, so as to improve the overall mechanical strength of the gear cover 400.

[0069] In order to further improve the assembly operability and stability of the gear cover 400 and the travel gear 300, please refer to Figure 4 and Figure 5 The cover body 410 of the embodiment is provided with a waist-shaped hole 412, and the travel gear 300 is provided with a plurality of locking holes 303, any one of which is used to connect a fastener to lock the relative position of the cover body 410 and the travel gear 300, and at least one locking hole 303 can be exposed from the waist-shaped hole 412 after the cover body 410 rotates relative to the travel gear 300. In this way, when assembling the gear cover 400 and the travel gear 300, at least one locking hole 303 can be exposed from the waist-shaped hole 412 regardless of the adjustment of the relative position of the gear cover 400 and the travel gear 300, and the exposed locking hole 303 can be used in cooperation with the fastener such as a bolt to realize the stable connection of the gear cover 400 and the travel gear 300.

[0070] It should be noted that when the gear cover 400 and the travel gear 300 are connected by the fastener, the fastener such as a bolt is threadedly connected with the hole wall of the locking hole 303, and the head of the fastener such as a bolt abuts against the cover body 410, so as to ensure the stability of the connection of the gear cover 400 and the travel gear 300 by the fastener such as a bolt.

[0071] Further, the plurality of locking holes 303 are sequentially and spacedly distributed around the rotation axis of the travel gear 300, and the waist-shaped hole 412 extends in an arc shape around the rotation axis of the cover body 410. In this way, at least one locking hole 303 can be effectively exposed from the waist-shaped hole 412 after the gear cover 400 rotates relative to the travel gear 300, and the gear cover 400 and the travel gear 300 can be stably connected by the fastener.

[0072] Alternatively, the travel gear 300 is further connected with a locking column 306, the locking column 306 is oppositely distributed with the locking hole 303, and the locking column 306 is located in the first ring gear hole 304; the fastener threadedly connected with the locking hole 303 is also threadedly connected with the locking column 306, so as to improve the stability of the locking member connected to the travel gear 300.

[0073] The cam (gear cover 400) of the travel adjusting mechanism provided by the related art can generally only rotate in one direction to actuate the micro switch 110, and if it is reversely rotated, the elastic sheet of the micro switch 110 is easily damaged.

[0074] To improve the above problems, please refer to Figure 4 In this embodiment, the protrusion 420 is connected to the outer periphery of the cover body 410, and the protrusion 420 includes a first inclined surface 421 and a second inclined surface 422, one end of the first inclined surface 421 is connected to one end of the second inclined surface 422, the other end of the first inclined surface 421 is connected to the cover body 410, the other end of the second inclined surface 422 is connected to the cover body 410, and the first inclined surface 421 and the second inclined surface 422 are distributed at an included angle; when the cover body 410 drives the protrusion 420 to rotate in a first direction, the first inclined surface 421 can abut or separate from the micro switch 110; when the cover body 410 drives the protrusion 420 to rotate in a second direction, the second inclined surface 422 can abut or separate from the micro switch 110; the first direction is opposite to the second direction. By arranging inclined surfaces on both sides of the protrusion 420, the protrusion 420 can be smoothly rotated to abut or separate from the spring of the micro switch 110 when the gear cover 400 rotates in any direction along the stroke gear 300 (i.e. whether the gear cover 400 rotates clockwise or counterclockwise), thereby improving the problem of the gear cover 400 damaging the spring of the micro switch 110.

[0075] Further, the connection between the first inclined surface 421 and the second inclined surface 422 is a circular arc transition. In this way, when the protrusion 420 rotates in any direction along the cover body 410, the protrusion 420 can be smoothly rotated to abut or separate from the micro switch 110 without being stuck by the spring of the micro switch 110, thereby ensuring the effectiveness of the stroke adjustment mechanism 010 of the clothes drying machine.

[0076] Further, the included angle between the first inclined surface 421 and the second inclined surface 422 is obtuse. Alternatively, the included angle between the first inclined surface 421 and the second inclined surface 422 is 100°-150°, for example: 100°, 110°, 120°, 130°, 140°, 150°, etc., which is not limited here.

[0077] Alternatively, the number of teeth of the first ring gear 301 can be 240-300; for every one tooth groove of the ratchet 432 of the clamping arm 430 of the gear cover 400 relative to the stroke gear 300, the corresponding winding groove of the winding gear 200 for winding or releasing the connecting rope can pass through an arc length of 7-10mm.

[0078] Optionally, the surface of the convex 420 is also provided with an indicating mark, such as an indicating arrow, and the shell 100 is also provided with a scale, so that when adjusting the stroke by rotating the gear cover 400 relative to the stroke gear 300, the purpose of quantitative adjustment of the stroke is achieved by cooperation of the indicating mark and the scale, that is, by rotating the indicating mark to be opposite to the corresponding scale; for example, the shell 100 is provided with 13 scales, one scale represents a stroke length of 5 cm, and the gear cover 400 drives the indicating mark to rotate one scale, so that the connecting rope is retracted or extended by 5 cm.

[0079] The stroke adjustment process of the stroke adjustment mechanism 010 of the clothes drying machine of the embodiment includes: loosening the fastener in the waist-shaped hole 412, rotating the gear cover 400 relative to the stroke gear 300, and then tightening the fastener in the waist-shaped hole 412.

[0080] In summary, the stroke adjustment mechanism 010 of the clothes drying machine of the present application can be used in a clothes drying machine, and the stroke adjustment mechanism 010 of the clothes drying machine has high structural strength and is not easy to be damaged by structure to cause the stroke adjustment mechanism to fail.

[0081] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
