Problems solved by technology

However, its disadvantage is that after the suction cup is pushed out, it is easy to be pushed back into the installation groove when people walk, so that the anti-skid effect is greatly weakened.

Embodiment Construction

[0051] Combine below Figure 1 to Figure 6 , the present invention is further described:

[0052] Such as figure 1 As shown, a kind of anti-skid shoe comprises sole 1 and vamp, and sole 1 has wear-resistant layer 11 and insole layer 12, and insole layer 12 is positioned at the top of wear-resistant layer 11, and wear-resistant layer 11 is in contact with the ground, and in wear-resistant layer 11 An automatic extension anti-skid device 2 is provided in the mounting hole 13.

[0053] Such as figure 2 As shown, the automatic stretching anti-skid device 2 includes a friction disc 21, a columnar water-expandable water-stop strip 22 and a connecting sleeve 24. The upper end of the water bar 22 is connected with the connecting sleeve 24 , and the upper end of the connecting sleeve 24 is connected with the bottom of the installation hole 13 of the wear-resistant layer 11 .

[0054] When the columnar water-expandable water-stop strip 22 is not in contact with water, the friction ...

Abstract

The invention relates to a friction disc locking mechanism for anti-sliding shoes. The friction disc locking mechanism (4) is used for preventing a friction disc (21) from retracting back into a mounting hole (13) after stretching out of the mounting hole (13) and comprises a driving block and a water-swelling water-sealing strip ring (42), wherein an annular cavity (15) is formed in an opening ofthe mounting hole (13), the water-swelling water-sealing strip ring (42) is arranged in the annular cavity (15) and is used for extruding the driving block along the horizontal direction, and an upper stressing oblique plane (41) is arranged at the upper part of the driving block; and a lower stressing oblique plane (211) is correspondingly arranged at the lower part of the friction disc (21), and the upper part of the friction disc (21) and the water-swelling water-sealing strip ring (42) form a limiting boss (212). The friction disc stretching out of the mounting hole is limited outside a sole by virtue of the friction disc locking mechanism, so that the friction disc is always outside the mounting hole during raining, and an increased friction force state of the sole is guaranteed.

Description

technical field [0001] The invention relates to a friction disk locking mechanism of anti-skid shoes, in particular to a friction disk locking mechanism of anti-skid shoes whose anti-skid effect only appears in rainy days and does not cause walking burden in fine weather. Background technique [0002] There is a lot of rain in the south, and the rain lasts for a long time, so people cannot avoid traveling. Therefore, for special groups: the elderly and pregnant women cannot avoid going out. [0003] Due to the heavy burden on the body, pregnant women face slippery ground. If they are not accompanied by someone, they are extremely prone to fall. The elderly in the south also often go out in rainy days, and have to face the problem of slippery ground. [0004] Therefore, there is an urgent need for a kind of safety anti-slip work shoes that can be used in rainy days in the current market, especially for the protection of the elderly and pregnant women. [0005] Prior art Ch...
