[0034] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0035] like Figure 1 , 2As shown in Figures 3, 4 and 5, an embodiment of the utility model discloses an anti-reversal hand-cranked clothes drying rack, comprising a shell 1, a handle 2 is rotatably provided on the shell 1, a rotating shaft 3 is fixedly connected to the handle 2, the rotating shaft 3 extends into the shell 1, a winding wheel 4 is fixedly sleeved on the rotating shaft 3, a locking mechanism 5 is provided on the rotating shaft 3, the locking mechanism 5 comprises a locking wheel 51 fixedly sleeved on the rotating shaft 3, eight protrusions 52 are evenly fixedly connected to the locking wheel 51 along the circumferential direction, a blocking rod 53 is rotatably provided on the shell 1, the bottom end of the blocking rod 53 is located between two adjacent protrusions 52, locking rods 54 are provided on both sides of the blocking rod 53, and the locking rods 54 can abut against the blocking rod 53.

[0036] Specifically, when in use, the pull rope is wound around the winding wheel 4, the pull rope extends out of the shell 1, and the extended end of the pull rope is connected to the clothes drying rack; in the initial state, the two locking rods 54 are respectively located on both sides of the blocking rod 53, and the locking rod 54 abuts against the side of the blocking rod 53, and the bottom end of the blocking rod 53 is located between two adjacent protrusions 52. At this time, the handle 2 is turned, the handle 2 drives the rotating shaft 3 to rotate, the rotating shaft 3 drives the locking wheel 51 to rotate, the locking wheel 51 drives the protrusion 52 to abut against the blocking rod 53, and the blocking rod 53 is clamped by the two locking rods 54 and cannot rotate, thereby jamming the rotating shaft 3 and locking the clothes drying rack; when the clothes drying rack needs to be raised, one of the locking rods 54 is moved so that the locking rod 54 is disengaged from the abutment with the blocking rod 53, and then the handle 2 is turned, the handle 2 drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the winding wheel 4 rotates, the winding wheel 4 winds the draw rope around the winding wheel 4, and the clothes drying rack is raised. At the same time, the rotating shaft 3 drives the locking wheel 51 to rotate, and the locking wheel 51 drives the protrusion 52 to rotate, and the protrusion 52 abuts against the bottom end of the blocking rod 53, driving the blocking rod 53 to swing. After the protrusion 52 and the blocking rod 53 are disengaged, the blocking rod 53 is reset under the action of its own weight, and then the blocking rod 53 abuts against the subsequent protrusion 52. When the user's hand leaves the handle 2, the clothes drying rack moves downward under the action of its own weight, driving the draw rope to disengage from the winding wheel 4, and the winding wheel 4 is reversed, and the winding wheel 4 drives the rotating shaft 3 to reverse, and the rotating shaft 3 drives the locking wheel 51 to reverse, and the locking wheel 51 drives the blocking rod 53 to swing in the opposite direction through the protrusion 52, and the blocking rod 53 is blocked by another locking rod 54 and stops rotating, thereby jamming the rotating shaft 3 to prevent the clothes drying rack from reversing when it is raised.

[0037] By setting the locking mechanism 5, when the clothes drying rack is raised, the blocking effect of the locking rod 54 on the blocking rod 53 can prevent the clothes drying rack from losing control and reversing when the user lets go of the clothes drying rack.

[0038] like Fig.12As shown, a torsion spring is provided at the rotational connection between the blocking rod 53 and the shell 1, the locking rod 54 extends out of the shell 1, and the extended end of the locking rod 54 is fixedly connected with an operating plate 55. Two magnetic rings 56 are fixedly sleeved on the locking rod 54, and the two magnetic rings 56 are respectively located on the outer side and the inner side of the shell 1, and the magnetic rings 56 can be magnetically attracted to the shell 1.

[0039] Specifically, during use, when the locking rod 54 needs to be abutted against the baffle rod 53, the locking rod 54 is pulled and moved by the operating plate 55, so that the magnetic ring outside the shell 1 is magnetically attracted to the shell 1, and the locking rod 54 is abutted against the baffle rod 53; when the locking rod 54 needs to be disengaged from the abutment with the baffle rod 53, the locking rod 54 is pulled and moved by the operating plate 55, so that the magnetic ring inside the shell 1 is magnetically attracted to the shell 1, and the locking rod 54 is disengaged from the abutment with the baffle rod 53.

[0040] The two magnetic rings 56 are provided to maintain the position of the locking rod 54 and ensure the stability of the device. Meanwhile, the operating panel 55 is provided to facilitate the operator to operate the locking rod 54 .

[0041] like Figure 1 , 3 As shown in , 5 and 9, the shell 1 is provided with an opening 6, and the pull rope passes through the opening 6. A partition mechanism 7 is provided in the opening 6, and the partition mechanism 7 includes a partition plate 71. The area of ​​the partition plate 71 is larger than the area of ​​the opening 6. A through hole 72 is provided on the partition plate 71, and a rubber ring is fixedly connected to the through hole 72, and the pull rope passes through the rubber ring.

[0042] Specifically, when in use, the partition plate 71 closes the opening 6 to prevent a large amount of dust from entering the housing 1 and affecting the internal structure of the housing 1 .

[0043] By setting the partition mechanism 7, the opening 6 can be closed to reduce the contact between the inside of the shell 1 and the outside world, while ensuring that the pull rope can enter and exit the shell 1, preventing a large amount of external dust from entering the shell 1 and affecting the internal structure of the shell 1.

[0044] like Figure 1 , 3 As shown in Figures 5 and 9, an axial sliding member 73 is provided between the partition plate 71 and the shell 1, and the axial sliding member 73 includes two T-shaped sliding grooves 731 with two openings upwardly opened in the partition plate 71, and the length direction of the sliding grooves 731 is parallel to the axial direction of the rotating shaft 3. Two T-shaped sliding blocks 732 are slidably connected in each of the sliding grooves 731, and the sliding blocks 732 are fixedly connected to the shell 1.

[0045] Specifically, during use, when the pull rope rotates on the winding wheel, due to the pressure between the pull ropes, the protruding end of the pull rope will move along the axial direction of the rotating shaft 3. When the pull rope moves along the axial direction of the rotating shaft 3, the pull rope will drive the partition plate 71 to move, and the partition plate 71 will drive the slide groove 731 and the slider 732 to move relative to each other, thereby preventing the pull rope from being subjected to excessive wear force from the through hole 72.

[0046] By setting the sliding member 73, the partition plate 71 can move along with the axis of the pull rope, thereby preventing the through hole 72 from excessively wearing the pull rope during the process of retracting and releasing the pull rope, thereby increasing the service life of the pull rope.

[0047] like Figure 1 As shown, the handle 2 includes a connecting rod, which is rotatably connected to the end of the rotating shaft 3. A handle is provided at one end of the connecting rod away from the rotating shaft 3, and the handle is rotatably connected to the rotating shaft 3.

[0048] Specifically, when the handle 2 needs to be rotated during use, the operator holds the handle and rotates the connecting rod, and the connecting rod drives the rotating shaft 3 to rotate.

[0049] like Figure 3 As shown, a closing cover is detachably connected to one end of the housing 1 away from the handle 2 , and the closing cover is rotatably connected to the rotating shaft 3 .

[0050] Furthermore, the closing cover is detachably connected to the housing 1 by bolts.
