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.

The invention discloses an outdoor expansion equipment, which comprises a bottom plate, a training unit, a rising unit and a mounting frame; the bottom plate: both sides of the upper surface of the bottom plate are respectively connected with the bottom ends of two mounting frames, and the inner sides of the two mounting frames are There is a chute, the top of the mounting frame is provided with a lifting unit, and the rear side of the mounting frame is provided with a protection unit; training unit: the training unit has two and is slidably connected with the chute on the inside of the two mounting frames , the training unit includes a fixed shaft, a slider, a connecting rod, a support rod, a support plate, a slide bar, a return spring, a movable plate and a handle, the inside of the handle is hollow, and the left end of the handle is connected to the slide The front side of the block is connected, the inside of the slider is hollow and communicates with the inside of the handle, the inside of the handle is vertically provided with a support plate, and the outside of the left end of the handle is provided with an opening. This outdoor expansion equipment has a simple structure and is easy to use. Convenience, high safety, no personal injury.

The invention relates to a nonslip shoe, comprising a sole (1) and an upper; the sole (1) is composed of a wear-resistant layer (11) and an insole layer (12) that is positioned above the wear-resistant layer (11); the wear-resistant layer (11) is in contact with a ground; an auto-extension nonslip device (2) is arranged in a mounting hole (13) of the wear-resistant layer (11). The nonslip shoe ischaracterized by also comprising a friction disc locking mechanism (4); the friction disc locking mechanism (4) prevents a friction disc (21) from retreating into the mounting hole (13) after the friction disc (21) is extended out of the mounting hole (13). The friction disc extended out of the mounting hole is limited outside the sole through the friction disc locking mechanism; it is ensured that the friction disc is constantly positioned outside the mounting hole during raining, and it is also ensured that friction of the insole increases.

The invention discloses a safety fall-preventing composite mechanism used for an inspection well. A through hole used for water circulating is formed in a well lid; a fall-preventing screen board comprises a positioning barrel, a plurality of radiant ribs and a plurality of reinforcing ribs, which are distributed in the shape of a spider web by taking the positioning barrel as a center, wherein the axial two end openings of an outer sleeve of a buffer mechanism are sealed by sealing plates; an inner sleeve penetrates through the sealing plates at the axial two end openings of the outer sleeveto be sleeved in the outer sleeve; a plurality of first through holes are formed in the sealing plate at the axial bottom end of the outer sleeve; a plurality of curved blade type strip-shaped shellswhich are distributed in the form of a turbine are arranged on the surface of the sealing plate at the axial top end of the outer sleeve in a convex mode; a plurality of liquid distributing holes areuniformly formed in the same side wall of a housing; the outer wall of one axial end of a central tube is rotatably connected with the inner wall of the inner sleeve through a bearing, and the other axial end of the central tube is movably connected with the positioning barrel; and a plurality of second through holes are formed in the side wall of the central tube. The safety fall-preventing composite mechanism is beneficial for effectively dispersing and weakening strong water flow impact force generated by return overflow, and is beneficial for preventing the well lid from being jacked to lose to cause casualties; and the fall-preventing screen board is stable and safe in structure.

The invention discloses a method for climbing a vertical ladder. The method comprises the following steps that a, a lifting rope is buckled with a vertical ladder climbing person, wherein the lifting rope is wound around a winding drum, the winding drum is rotationally mounted on a transverse supporting rod at the top of the vertical ladder and is in driving connection with a driving motor, and a rotary shaft of the winding drum is rotationally connected with a brake signal transmitting structure and a brake structure; and b, when the vertical ladder climbing person climbs upwards, the driving motor lifts the lifting rope and assists the vertical ladder climbing person in climbing upwards, the driving motor is stopped when the vertical ladder climbing person climbs down, the brake signal transmitting structure acquires the rotating speed of the winding drum in real time, whether the vertical ladder climbing person falls off or not is judged through the rotating speed, and the brake signal transmitting structure triggers the brake structure to stop the winding drum from rotating to prevent falling when the vertical ladder climbing person falls off. According to the method for climbing the vertical ladder, more labor can be saved when the person climbs the vertical ladder, falling prevention can be achieved better, and the safety of the safety climbing person is ensured.
