[0002] At present, a known hand crank for a drying rack, when the handle is turned to exhaust the steel wire rope wound on the I-shaped wheel, if it continues to rotate, the exhausted steel wire rope will be reversely wound and retracted at this time, causing the steel wire rope to fold repeatedly, which is easy break, and it is also difficult for users to judge the winding direction of the lift
[0003] Patent No.: 201420503023.X, which discloses an anti-reverse hand crank, which reverses when the wire rope is put to the end, and uses the wire rope to touch the anti-rotation block in reverse, so that the anti-rotation block blocks the worker. The anti-reverse clamping position of the word wheel prevents the I-shaped wheel from continuing to reverse and achieves the purpose of anti-reverse, but the wire rope of the anti-reverse hand crank needs to touch the anti-rotation block in reverse, and the wire rope is easy to break due to reflexion , and it is easy to fall off from the fixed grain at the end of the fixed wire rope

Embodiment 1

[0064] Such as Figure 1 to Figure 18 As shown, the anti-reverse hand crank of embodiment one includes: handle 8, large cup 7, main shaft 10, front I-shaped wheel 4, rear I-shaped wheel 1, anti-rotation pin 5, anti-reverse and anti-off cover 2, Locking pin torsion spring 6, self-locking spring mechanism 9 and steel wire rope 3. Among them, the mirror image of the front and rear I-shaped wheels is symmetrical, and the design principles are consistent. For example, the previous I-shaped wheel 4, such as Figure 5 , Image 6 As shown, the surface of the wheel shaft 41 of the front I-shaped wheel 4 is provided with a horizontal step-type concave anti-rotation card position 411, and the side of the wheel shaft 41 is provided with a fixed grain hidden groove 413 and a steel wire rope hidden groove 412 for hiding the initial section of the steel wire rope. The hidden groove 412 is along the winding direction of the wire rope, the starting end is connected to the fixed particle hidi...

Embodiment 2

[0072] Such as Figure 27 to Figure 30 As shown, the difference between the second embodiment and the first embodiment only lies in the installation position of the anti-rotation pin 5, and the rest are the same.

Embodiment 3

[0074] Such as Figure 31 to Figure 34 As shown, the difference between the third embodiment and the first embodiment is that the third embodiment is not provided with a wire rope hidden groove on the side of the I-shaped wheel axle to hide the initial section of the wire rope, and the rest are the same. The I-shaped wheel in the third embodiment reverses and releases the steel wire rope, and when the steel wire rope has about half a turn left, the anti-rotation pin is locked in the detent position to prevent the I-shaped wheel from continuing to reverse. Because there is no wire rope hidden groove for hiding the initial section of the wire rope on the side of the I-shaped wheel axle, the protection effect of the steel wire rope in the third embodiment is inferior to that in the first embodiment.

[0075] Such as Figure 31 with Figure 33 As shown, the angle between the anti-rotation clamping position of the third embodiment and the hidden groove of the fixed grain of the s...

Abstract

A new type of anti-reversal hand crank for drying racks, comprising an I-shaped wheel wound with a steel wire rope and an anti-rotation pin, the surface of the axle of the I-shaped wheel is provided with an anti-rotation stop, one end of the anti-rotation pin is hinged, and the other is One end leans against the axle surface of the I-shaped wheel, and cooperates with the anti-rotation card on the surface of the I-shaped wheel axle; when the I-shaped wheel is reversed, the wire rope is released to the anti-rotation card on the surface of the I-shaped wheel axle. It is stuck against the detent stop and prevents the I-wheel from continuing to reverse. When the I-wheel rotates forward, the detent pin follows the detent and the I-wheel winds the wire rope smoothly. A torsion spring of the detent pin may also be included, and the torsion spring of the detent pin elastically presses the detent pin against the axle surface of the I-shaped wheel. The side of the I-shaped wheel axle can be provided with a steel wire rope fixed grain hidden groove, and can also be provided with a steel wire rope hidden groove for hiding the initial section of the steel wire rope, and the steel wire rope hidden groove is connected with the steel wire rope fixed grain hidden groove. The invention makes the wire rope not easy to break and fall off, and effectively improves the service life and safety.

Description

technical field [0001] The invention relates to a novel anti-reversal hand crank for a clothes rack, which is used to prevent the hand crank of a clothes hanger from continuing to revolve after the steel wire rope is exhausted. Background technique [0002] At present, a known hand crank for a drying rack, when the handle is turned to exhaust the steel wire rope wound on the I-shaped wheel, if it continues to rotate, the exhausted steel wire rope will be reversely wound and retracted at this time, causing the steel wire rope to fold repeatedly, which is easy Fracture, and it is also difficult for users to judge the winding direction of the lift. [0003] Patent No.: 201420503023.X, which discloses an anti-reverse hand crank, which reverses when the wire rope is put to the end, and uses the wire rope to touch the anti-rotation block in reverse, so that the anti-rotation block blocks the worker. The anti-reverse clamping position of the word wheel prevents the I-shaped wheel ...
