Description

Technical Field

[0001] This utility model relates to the technical field of trapezoidal stabilization devices, and in particular to a stable anti-tilting A-type ladder. Background Technology

[0002] Currently, almost all A-frame ladders available on the market have anti-expansion devices as safety features, which prevent the opening angle of the A-frame ladder from increasing during use and causing injury to the user.

[0003] Currently, there are few safety devices that ensure the lateral stability of ladders during use and prevent tipping. Furthermore, the support legs of A-type ladders with anti-tilting installation devices are fixed, which limits their use in confined spaces.

[0004] In other words, the existing A-type ladder has the following main drawbacks:

[0005] (1) If the A-type ladder shakes slightly when the staff are using it, it is easy to tip over and cause harm to the human body;

[0006] (2) The safety device is of a single type, and the fixed safety device can easily lead to the overall size of the ladder being too large, thus limiting its use scenarios. Utility Model Content

[0007] The purpose of this invention is to provide a stable anti-tilting A-type ladder, which has good stability during use and can effectively prevent the A-type ladder from tilting.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] A stable anti-tilting A-type ladder includes: an A-type ladder body, and anti-tilting devices are respectively assembled and connected to both sides of the two legs of the A-type ladder body;

[0010] The anti-tilt device includes: a support body, wherein the head of the support body is cut into a circle and the tail is cut into a 45° triangle, and an anti-slip rubber sleeve is wrapped around the tail.

[0011] The support body can be in an open state with its head as a fulcrum, with the legs away from the A-type ladder body, or in a closed state with the legs close to the A-type ladder body.

[0012] In practical applications, the head of the support body has a circular hole with a diameter of 20cm in the middle, and a circular hole with a diameter of 1cm 5cm away from the head hole, for inserting a pin and assembling it with the fixing device at the support leg of the A-type ladder body.

[0013] The fixing device uses 55mm×55mm aluminum alloy C-shaped steel cut into 15cm sections, and four holes are drilled at the four corners of the back of the C-shaped steel. The C-shaped steel is fixed to the support leg of the A-type ladder body at 30cm by bolts. The C-shaped steel has 20cm round holes in the middle of both sides, and the C-shaped steel is connected and fixed to the support leg by a pivot.

[0014] Specifically, the upper part of the C-shaped steel has a 1cm circular hole 5cm away from the central hole, which is used for fixing the bracket body with a pin when it is closed.

[0015] Specifically, the C-shaped steel has a circular hole 5cm away from the center pivot on the side of the support body, which is used to fix the support body with a pin when it is opened.

[0016] Furthermore, the support body is made of 50mm×50mm aluminum alloy square tube and has a length of 60cm.

[0017] Preferably, the opening angle between the support body and the legs of the A-type ladder body is 53.13°.

[0018] Compared with existing technologies, the stable anti-tilting A-type ladder of this utility model has the following advantages:

[0019] The stable anti-tilting A-type ladder provided by this utility model has anti-tilting devices installed on both sides of the two legs of the A-type ladder body. Each anti-tilting device includes a support body with a circular head and a 45° triangular tail, covered with an anti-slip rubber sleeve. The support body can open with the legs furthest from the A-type ladder body as a fulcrum, or close with the legs closest to the A-type ladder body. Therefore, the stable anti-tilting A-type ladder provided by this utility model can maximize the prevention of tilting during use, exhibiting excellent stability. Furthermore, the support body can be opened during use and retracted when not in use, resulting in a small space occupation when retracted, facilitating storage and movement, and thus providing good flexibility. In addition, it is easy for users to operate and master, has reliable connection quality, and the modified anti-tilting device is low-cost, allowing for mass production and wide applicability.
