Detailed ways

The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

As shown in Figure 1, this dual-purpose pulley shoe comprises upper 1, sole 2 and movable pulley block 3, and sole 2 is provided with a groove 4, is provided with two movable pulley blocks 3 one after another in the groove 4, movable pulley block 3 It can rotate relative to the groove 4. Movable pulley block 3 turns outwards and unfolds, and when being positioned at the front and rear ends of groove 4, the present invention can be used as pulley shoes. And when the movable pulley block 3 turns inwards and shrinks and is positioned at the groove 4 middle part, the present invention can be used as common shoes.

As shown in Figure 2, movable pulley block 3 all comprises bracket 31, pulley 32, rotating shaft 33 and connecting shaft 34, and bracket 31 then comprises the force receiving part 31a and connecting part 31b that are connected together, and connecting part 31b connects with concave through connecting shaft 34. The inner side wall of the groove 4 is rotationally connected, and the pulley 32 is connected with the connecting portion 31b through a rotating shaft 33. When the pulley 32 is in an everted state, the force receiving portion 31a is located between the bottom of the groove 4 and the pulley 32, and the force receiving portion 31a The force-receiving surface 31a1 of the pulley 32 is just in close contact with the bottom of the groove 4, and the two sides of the pulley 32 are also provided with supporting parts 31c connecting the force-receiving part 31a and the connecting part 31b. In order to ensure stability, a deeper recess 41 is provided at the bottom of the groove 4, and the force-bearing surface 31a1 of the force-receiving part 31a falls into the recess 41, and the recess 41 only limits the force-receiving part 31a falling inside. .

As shown in Figure 3, a pin hole 5 and two sliding passages 6 are opened on the force receiving part 31a, the pin hole 5 runs through the force receiving part 31a and two latches 7 are provided, and a return spring 8 is arranged between the two latches 7 , the pin hole 5 and the sliding channel 6 are connected to each other to form a "[" shape, and each sliding channel 6 is provided with a driving rod 9, the inner end of the driving rod 9 is vertically connected with the latch 7 on the corresponding side, and the outer end extends out of the sliding channel 6.

As shown in FIG. 4 , one of the two movable pulley blocks 3 in the groove 4 is in an eversion-expanded state, and the other is in a retracted state. When in the state of eversion and expansion, the two pins 7 on both sides of the movable pulley block 3 are inserted into the jacks 42 on the inner wall of the groove 4 near the end of the groove 4, and the sole 2 has a lever 9 near the movable pulley block 3. Notch 21. And when being in contraction state, two latches 7 on both sides on movable pulley block 3 are then inserted in the jack 42 near groove 4 middle part on the groove 4 inwall, and sole 2 middle parts are provided with near this movable pulley block 3 driving lever 9 equally. The notch 21.

When it needs to be used as a pulley shoe, the movable pulley block 3 is turned out to the two ends of the groove 4, and the two driving levers 9 are moved inward, so that the two latches 7 in the same pin hole 5 move towards each other, and the return spring 8 is compressed. , after vacating the gap, smoothly slide into the groove 4, then loosen the shift lever 9, the latch 7 resets under the action of the return spring 8, and inserts each into the jack 42 on the corresponding side to complete the locking. At this time, the pulley 32 is deployed outside the sole 2 and directly touches the ground (as shown in FIG. 1 ).

When it needs to be used as an ordinary shoe, the fingers are inserted into the groove 4, and at the same time, the two levers 9 on the same movable pulley block 3 are moved inwardly, so that the latch 7 is retracted into the pin hole 5 to complete the unlocking. The notch 21 makes it easy for fingers to touch the lever 9, and then the movable pulley block 3 can be reversed, and the pulley 32 can be retracted into the groove 4. After the lever 9 is released, the latch 7 is reset to complete the locking. At this time, the surrounding area of the groove 4 2 parts of the sole touch the ground.

When it needs to be used as a pulley shoe again, the principle is the same as above, first unlock and then turn over, and lock after the turnover is completed, so as to achieve the dual-use effect of general shoes and pulley shoes. At the locked position of each latch 7, there is a notch 21 which is convenient for fingers to touch the driving rod 9.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which the present invention belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, but they will not deviate from the spirit of the present invention or go beyond the definition of the appended claims range.
