Description

Technical Field

[0001] The utility model relates to the technical field of ladders, in particular to an anti-slip ladder. Background Art

[0002] In daily life and work, ladders are usually needed to facilitate climbing or maintenance work. During use, one end of the ladder is placed against the wall and the other end is on the ground. Since most ladders are not equipped with relevant anti-slip measures, in order to prevent people from slipping when climbing or standing on the ladder, one or two people are needed to hold the ladder when one person goes up to work to prevent the ladder from slipping along the ground. In response to the above-mentioned technical problems, a utility model patent with announcement number CN202417296U discloses an anti-slip ladder, in which a ground fixer is provided at the lower part of the ladder body. When the ladder is against the wall, the support block connected to the ground fixer and the lower shaft of the ladder body can adaptively contact the ground. After the ladder body is placed on the wall, it will not slide due to the problem of the ground fixer.

[0003] As is known to all, when a ladder is used in an inclined state, the stability and reliability of the ladder depends entirely on whether the force applied to the lower end of the ladder after contacting the ground is stable; however, when the above technical solution is in use, since the ground anchor is directly connected to the lower end of the ladder body through an axis, there is only one connection point between the ground anchor and the ladder body. When the ladder body is tilted, it is difficult for the lower end of the ladder body to form a stable downward pressure on the ground anchor, resulting in a significant reduction in the friction between the ground anchor and the ground, which will affect the anti-slip effect of the ladder body. Summary of the invention

[0004] In order to solve the technical problems existing in the above technology, it is necessary to provide an anti-slip ladder.

[0005] The invention discloses an anti-slip ladder, comprising a ladder body, wherein the two lower ends of the ladder body are respectively provided with anti-slip devices, wherein the anti-slip devices comprise a support rod and an anti-slip plate; one end of the anti-slip plate is rotatably connected to the lower end of the ladder body and can freely rotate with the length of the anti-slip plate as a radius; the upper end of the support rod is rotatably connected to the ladder body, the lower end of the support rod is detachably connected to the anti-slip plate, and the lower end of the support rod can adjust the installation position along the length direction of the anti-slip plate to achieve the adjustment of the angle between the anti-slip plate and the ladder body.

[0006] Preferably, an anti-slip pad is provided at the bottom of the anti-slip plate.

[0007] Preferably, the bottom of the anti-slip pad is provided with anti-slip protrusions.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner", "lower" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0025] Please see Figure 1 , Figure 2 ,as well as Figure 5The present invention provides an anti-slip ladder, including a ladder body 01, and anti-slip devices 02 are correspondingly provided at the two lower ends of the ladder body 01, wherein the anti-slip device 02 includes a support rod 21 and an anti-slip plate 22; one end of the anti-slip plate 22 is rotatably connected to the lower end of the ladder body 01, and the end can freely rotate with the length of the anti-slip plate 22 as a radius, the upper end of the support rod 21 is rotatably connected to the ladder body 01, the lower end of the support rod 21 is detachably connected to the anti-slip plate 22, and the lower end of the support rod 21 can adjust the installation position along the length direction of the anti-slip plate 22 to achieve the adjustment of the angle between the anti-slip plate 22 and the ladder body 01. When in use, the lower end of the ladder body 01 can apply downward pressure to one end of the anti-slip plate 22, and when the ladder body 01 presses down the support rod 21, one end of the support rod 21 can apply downward pressure to the other end of the anti-slip plate 22. This not only forms a Y-shaped structure between the ladder body 01 and the support rod 21 to balance the pressure on the anti-slip plate 22 and keep the anti-slip plate 22 stable, but also a triangular structure can be formed by the support rod 21, the anti-slip plate 22, and the lower part of the ladder body 01, thereby ensuring the stability of the overall structure.

[0026] Please see Figure 6 Specifically, in order to improve the anti-skid effect of the anti-skid plate 22, an anti-skid pad 03 is provided at the bottom of the anti-skid plate 22, and the anti-skid pad 03 is made of rubber. In order to increase the grip effect, an anti-skid protrusion 31 is provided at the bottom of the anti-skid pad 03. The anti-skid protrusion 31 is in a V-shaped structure.

[0027] Specifically, the anti-slip plate 22 is provided with through holes 221 evenly spaced along the length direction of the anti-slip plate 22, and the lower end of the support rod 21 is pinned to the through holes 221. By pinning the lower end of the support rod 21 to different through holes 221, the angle between the anti-slip plate 22 and the ladder body 01 can be adjusted to meet different usage requirements.

[0028] Specifically, a groove 11 is provided on one side surface of the ladder body 01 close to the support rod 21, and the groove 11 can accommodate the support rod 21; when not in use, the support rod 21 can be bent and stored in the groove 11, and the anti-slip plate 22 can be folded and placed against the lower part of the ladder body 01.

[0029] Please see Figure 3 , Figure 4 ,as well as Figure 7 Specifically, the two ends of the anti-slip plate 22 are respectively provided with U-shaped anti-slip grooves 04, the opening of the U-shaped anti-slip grooves 04 faces the ground, and the lower end of the U-shaped anti-slip grooves 04 is sawtooth-shaped, and the lower end of the sawtooth structure 41 is inclined, and the inclined direction is opposite to the sliding direction of the ladder body 01, so as to ensure that it has a stronger grip. During use, the U-shaped anti-slip grooves 04 can get stuck on the ground to provide greater resistance to prevent the ladder body 01 from tilting and slipping, so as to ensure the safety of personnel.

[0030] Among them, one end of the U-shaped anti-skid groove 04 is rotatably connected to the anti-skid plate 22, and the end can rotate 180 degrees with the length of the U-shaped anti-skid groove 04 as a radius. At the two ends of the anti-skid pad 03, there are corresponding concave platforms, so that the U-shaped anti-skid groove 04 can be accommodated in the concave platform after being turned over and folded. When it is needed, the end of the U-shaped anti-skid groove 04 with the serrated structure 41 can be rotated to face the ground. At this time, the side of the U-shaped anti-skid groove 04 close to the anti-skid plate 22 will abut against the end of the anti-skid plate 22, thereby providing a limit for the U-shaped anti-skid groove 04, so that the U-shaped anti-skid groove 04 remains horizontal to provide better grip. When not in use, the end of the U-shaped anti-skid groove 04 with the serrated structure 41 can be rotated to face upward, and the end with the serrated structure 41 can be rotated to engage with the bottom of the anti-skid plate 22, so as to facilitate storage; in this way of use, it can also be used for floor surfaces, such as wooden floors or tile floors. After the U-shaped anti-skid groove 04 is folded, the anti-skid pad 03 can be used to provide friction resistance, which can not only prevent slipping, but also prevent scratches on the floor.

[0031] What is disclosed above is only a preferred embodiment of the present invention, which certainly cannot be used to limit the scope of rights of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
