Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Examples

Referring to fig. 1-3, the present invention provides a technical solution: a foldable anti-skid ladder comprises a frame body 1, wherein pedals 2 are evenly hinged to the inner side of the frame body 1, a connecting rod 3 is hinged to one side, away from the frame body 1, of each pedal 2, supporting legs 5 are hinged to the top of the frame body 1, a cavity 6 is arranged in each pedal 2, a cylinder body 7 is evenly fixed to the bottom of the inner side of each cavity 6, a slider 10 is connected to the inner cavity of each cylinder body 7 in a sliding mode, a movable column 11 is fixed to the top of each slider 10, a groove 13 is formed in the upper portion of each movable column 11, the bottom of each slider 10 is connected to the bottom of the inner cavity of each cylinder body 7 through a spring 12, an air inlet pipe 8 is communicated to one side of each pedal 2, a guide cylinder 14 sleeved on the outer side of each movable column 11 is fixed to the top of each pedal 2, a sealing ring 15 sleeved on the outer side of each movable column, the upper portion of support body 1 articulates there is dead lever 19, one side that dead lever 19 kept away from support body 1 is through the inboard of the solid top of screw in supporting leg 5.

Specifically, an air hole 16 is formed in one side of the bottom of the cylinder body 7; so that the sliding block 10 can move rapidly, and a gap is reserved between the top of the cylinder body 7 and the movable column 11, so that the sliding block 10 can move smoothly. The upper part of the movable column 11 is provided with a limiting part 18, and the top of the limiting part 18 is fixed with a rubber pad 17; the stopper 18 prevents the movable post 11 from being completely retracted into the cavity 6 for improved slip resistance. The number of the grooves 13 is not less than five, and the grooves 13 are uniformly distributed on the outer side of the movable column 11 in an annular shape; so that the gas can be sprayed all around when being discharged through the grooves 13. The inner side of the supporting leg 5 is uniformly provided with screw holes 20, and the fixing rod 19 is connected to the inner side of the screw holes 20 through screws; different screw holes 20 are conveniently connected with the fixed rod 19 to adjust the unfolding state of the ladder. An air pump 9 is arranged on one side of the bottom of the frame body 1, and an air outlet of the air pump 9 is communicated with an air inlet pipe 8 through a pipeline; the air pump 9 is used for filling air into the cavity 6.

When the device is used, the supporting legs 5 and the frame body 1 are unfolded, the adjusting state is determined, and the fixing rod 19 is rotated to enable a screw to be inserted into the fixing rod 19 and then to be in threaded connection with the corresponding screw hole 20; draw connecting rod 3 and make footboard 2 expand, receive the spacing post 4 in bottom to block when footboard 2 rotates, can be so that footboard 2 is in the state of keeping flat. When dust on the top of the pedal 2 needs to be removed in real time, the air pump 9 is started, so that the air pump 9 fills air into the cavity 6 through the air inlet pipe 8; a tank body communicated with the air inlet pipe 8 and the air outlet of the air pump 9 can be added at a pipeline connected between the air outlet of the air pump 9 and the air inlet pipe 8 and used for storing high-pressure air; when the people is stepping on and pressing footboard 2, the foot pushes down the activity post 11 that the sole portion corresponds for the activity post 11 that is not stepped on can enclose the fender to the foot, can contradict activity post 11 on every side and stop sliding when making the foot slide, thereby reaches anti-skidding effect, improves the security. After the movable column 11 is pressed down by the foot, the groove 13 moves down along with the movable column 11, so that gas in the cavity 6 can be sprayed outwards through the groove 13, and the sprayed gas can blow off dust and sand on the surfaces of the sole and the pedal 2, so that the phenomenon that the sole slips due to the rolling of the sand is avoided, the skid resistance is further improved, and the safety of idle operation is improved.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
