[0003] In order to solve the above problems existing in the prior art, the purpose of the utility model is to provide an anti-slip ladder to improve the anti-slip performance of the ladder, thereby improving the safety of production work of people and objects.

[0004] The technical solution adopted by the utility model is:

[0005] A non-slip ladder comprises a main ladder, an auxiliary ladder is rotatably connected to the main ladder, and a retractable connecting rod is rotatably connected between the main ladder and the auxiliary ladder; the retractable connecting rod comprises a first connecting rod, an intermediate rod and a second connecting rod, one end of the first connecting rod is rotatably connected to the main ladder, one end of the second connecting rod is rotatably connected to the auxiliary ladder, and the intermediate rod is threadedly connected to the first connecting rod and the second connecting rod respectively.

[0006] The utility model adds an auxiliary supporting ladder under the existing ordinary ladder, and a telescopic connecting rod is provided between the main ladder and the auxiliary ladder to adjust the angle between the two ladders. In this way, the sliding forces of the ladder feet of the main ladder and the auxiliary ladder on the ground are in opposite directions and offset each other (or partially offset), thereby improving the anti-slip performance of the entire ladder.

[0007] The middle rod of the telescopic connecting rod is threadedly connected to the first connecting rod and the second connecting rod respectively, so that the total length of the telescopic connection can be adjusted by screwing the middle rod, so that the angle between the main ladder and the auxiliary ladder can be easily adjusted.

[0008] As a preferred solution of the utility model, the threads of the first connecting rod and the threads of the second connecting rod have opposite rotation directions. Since the threads of the first connecting rod and the second connecting rod have opposite rotation directions, when the middle rod is rotated in one direction, the first connecting rod and the second connecting rod extend relative to the middle rod, and when the middle rod is rotated in the other direction, the first connecting rod and the second connecting rod retract relative to the middle rod, thereby achieving the adjustment of the total length of the adjustable connecting rod.

[0009] As a preferred solution of the utility model, a connecting ear is provided on one side of the main ladder, and the upper end of the auxiliary ladder is rotatably connected to the connecting ear. The connecting ear is provided on one side of the main ladder to prevent the connecting ear from blocking the crossbar on the main ladder, thereby preventing the connecting ear from blocking users from going up and down the ladder.

[0010] As a preferred solution of the utility model, the main ladder includes a plurality of main ladder cross bars, one of which is sleeved with a first sleeve, and the first sleeve is fixed to the first connecting rod. The first sleeve is sleeved on the main ladder cross bar, thereby ensuring that the first connecting rod is reliably connected to the main ladder.

[0011] As a preferred solution of the utility model, the auxiliary ladder includes a plurality of auxiliary ladder cross bars, one of which is sleeved with a second sleeve, and the second sleeve is fixed to the second connecting rod. The second sleeve is sleeved on the auxiliary ladder cross bar, thereby ensuring that the second connecting rod is reliably connected to the auxiliary ladder.

[0012] As a preferred solution of the utility model, a handle is connected to the middle rod, and the middle rod can be rotated by holding the handle, which can save labor.

[0013] As a preferred solution of the utility model, the handle includes a plurality of operating rods evenly distributed on the middle rod.

[0014] As a preferred solution of the utility model, the bottom of the main ladder is rotatably connected to a main ladder foot. The main ladder foot is rotatably connected to the main ladder to ensure that the main ladder foot can be reliably pressed on the ground. Anti-skid teeth are provided on the bottom surface of the main ladder foot to further improve the anti-skid ability of the ladder.

[0015] As a preferred solution of the utility model, the bottom of the auxiliary ladder is rotatably connected to an auxiliary ladder foot. The auxiliary ladder foot is rotatably connected to the auxiliary ladder to ensure that the auxiliary ladder foot can be reliably pressed on the ground. Anti-skid teeth are provided on the bottom surface of the auxiliary ladder foot to further improve the anti-skid ability of the ladder.

[0016] As a preferred solution of the utility model, the auxiliary ladder is rotatably connected to the middle and lower sections of the main ladder.

[0017] The beneficial effects of the utility model are:

[0018] 1. The utility model adds an auxiliary supporting ladder under the existing ordinary ladder, and a telescopic connecting rod is provided between the main ladder and the auxiliary ladder to adjust the angle between the two ladders. In this way, the sliding forces of the ladder feet of the main ladder and the auxiliary ladder on the ground are in opposite directions and offset each other (or partially offset), thereby improving the anti-slip performance of the entire ladder.

[0019] 2. The middle rod of the telescopic connecting rod is threadedly connected to the first connecting rod and the second connecting rod respectively, so that the total length of the telescopic connection can be adjusted by screwing the middle rod, so that the angle between the main ladder and the auxiliary ladder can be easily adjusted.

[0028] The utility model adds an auxiliary supporting ladder under the existing ordinary ladder, and a telescopic connecting rod 3 is provided between the main ladder 1 and the auxiliary ladder 2 to adjust the angle between the two ladders. In this way, the sliding forces of the ladder feet of the main ladder 1 and the auxiliary ladder 2 on the ground are in opposite directions and offset each other (or partially offset), thereby improving the anti-slip performance of the entire ladder.

[0029] The middle rod 32 of the telescopic connecting rod 3 is threadedly connected to the first connecting rod 31 and the second connecting rod 33 respectively, so that the total length of the telescopic connection can be adjusted by screwing the middle rod 32, so that the angle between the main ladder 1 and the auxiliary ladder 2 is conveniently adjusted.

[0030] It should be noted that the threads of the first connecting rod 31 and the threads of the second connecting rod 33 are in opposite directions. Since the threads of the first connecting rod 31 and the threads of the second connecting rod 33 are in opposite directions, when the intermediate rod 32 is rotated in one direction, the first connecting rod 31 and the second connecting rod 33 extend relative to the intermediate rod 32, and when the intermediate rod 32 is rotated in the other direction, the first connecting rod 31 and the second connecting rod 33 retract relative to the intermediate rod 32, thereby achieving the adjustment of the total length of the adjustable connecting rods.

[0033] The auxiliary ladder 2 includes a plurality of auxiliary ladder cross bars, one of which is sleeved with a second sleeve 35, which is fixed to the second connecting rod 33. The second sleeve 35 is sleeved on the auxiliary ladder cross bar, thereby ensuring that the second connecting rod 33 is reliably connected to the auxiliary ladder 2.

[0034] Furthermore, a handle 4 is connected to the intermediate rod 32. By holding the handle 4 to rotate the intermediate rod 32, labor saving can be achieved.

[0035] The handle 4 includes a plurality of operating rods 41 evenly distributed on the middle rod 32 .

[0036] Furthermore, the bottom of the main ladder 1 is rotatably connected to a main ladder foot 5. The main ladder foot 5 is rotatably connected to the main ladder 1 to ensure that the main ladder foot 5 can be reliably pressed on the ground. The bottom surface of the main ladder foot 5 is provided with anti-skid teeth to further improve the anti-skid ability of the ladder.

[0037] The bottom of the auxiliary ladder 2 is rotatably connected with an auxiliary ladder foot 6. The auxiliary ladder foot 6 is rotatably connected to the auxiliary ladder 2 to ensure that the auxiliary ladder foot 6 can be reliably pressed on the ground. The bottom surface of the auxiliary ladder foot 6 is provided with anti-skid teeth to further improve the anti-skid ability of the ladder.
