Description

Technical Field

[0001] This utility model relates to the field of ladder technology, specifically to a ladder with self-adjusting bias support legs. Background Technology

[0002] Ladders, as a common tool for climbing, are widely used in various fields such as construction, home repair, and warehousing and logistics. Whether for professional workers or ordinary household users, ladders are an indispensable tool.

[0003] Traditional ladders have a relatively simple structure, typically consisting of two uprights and several fixed steps. While this design meets basic climbing needs, it has several shortcomings in practical use. First, the fixed legs make them difficult to adapt to uneven or soft ground, easily causing the ladder to tilt or even fall over, posing a significant safety hazard. This is especially true in complex work environments, such as construction sites or outdoor work, where ground conditions are often unsatisfactory, making it difficult for ladders with fixed legs to maintain stability and increasing the risk to the user. Second, traditional ladders are not very portable. Due to their fixed structure and large size, they are relatively inconvenient to move and store, especially in situations requiring frequent ladder movement, such as home repairs or outdoor work.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an adaptive adjustable ladder with bias support legs to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An adaptive adjustable ladder with biased support legs includes two uprights. One upright is rotatably connected to a first step, and the other upright is rotatably connected to a second step. The first step and the second step are hinged together. A first hinge seat is connected to one side of the bottom end of the upright. The first hinge seat is connected to a telescopic rod. The bottom end of the telescopic rod is connected to the second hinge seat. A fixing plate is provided on one side of the second hinge seat. The fixing plate has a first threaded hole, and an anchor rod is threaded into the first threaded hole.

[0008] Furthermore, to facilitate the rotation of the anchor bolt, the top of the anchor bolt is connected to a rotating plate.

[0009] Furthermore, the telescopic rod includes a fixed rod and a movable rod. The movable rod is slidably connected inside the fixed rod. The fixed rod is provided with a second threaded hole, and a bolt is threaded inside the second threaded hole. One end of the bolt abuts against the movable rod.

[0010] Furthermore, to ensure the ladder remains stable when unfolded, a connecting rod is connected to one side of one of the columns, and a connecting plate is fitted on the outer side of the connecting rod. One end of the connecting plate has a through hole, and a screw is connected to one side of the other column, with the through hole matching the screw.

[0011] Furthermore, in order to fix the connecting plate, a nut is threaded onto the screw, and the nut is located on the outside of the connecting plate.

[0012] Furthermore, a limit plate is connected to one end of the connecting rod.

[0013] Furthermore, there are two connecting rods, one at the top and one at the bottom of the column.

[0014] Furthermore, the bottom of the column is connected with an anti-slip pad.

[0015] The beneficial effects of this utility model are as follows:

[0016] (1) By setting a first hinge seat and telescopic rod connection structure at the bottom of the column, and cooperating with the second hinge seat, ground fixing plate and anchor rod, the ladder can be firmly fixed to the ground. When the ladder is unfolded and used, it can be inserted into the ground by rotating the anchor rod, which effectively prevents the ladder from sliding or tipping over. Especially when the wind is strong and the ground is uneven, they can be offset or tilted at a certain angle to adapt to the uneven ground.

[0017] (2) By setting the first step and the second step, the uprights and the steps are connected by a rotating rod, so that the whole ladder can be easily folded into a compact shape, which is convenient for transportation and storage. By setting the locking mechanism consisting of connecting rod, connecting plate, screw and nut, when the ladder is unfolded, the two uprights can be effectively fixed together by putting the connecting plate into the screw and tightening the nut, so as to prevent shaking or deformation caused by external force.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] According to an embodiment of the present invention, a ladder with adaptive adjustment of bias support feet is provided.

[0027] Example 1

[0028] like Figures 1-4As shown, the self-adjusting ladder with bias support feet according to an embodiment of this utility model includes two uprights 1. The uprights 1 serve as the main support structure of the ladder, providing vertical support for the entire ladder. One upright 1 is rotatably connected to a first footplate 2 via a pivot, and the other upright 1 is rotatably connected to a second footplate 3 via a pivot. The first footplate 2 and the second footplate 3 are hinged together. The footplates are used for standing. The rotatable connection design allows the ladder to be folded up when not in use for easy carrying and storage. A first hinge seat 4 is connected to one side of the bottom of the upright 1, serving to connect the upright 1 and the telescopic rod 5. The first hinge seat 4 is connected to the telescopic rod 5. The telescopic rod 5 includes a fixed rod 11 and a movable rod 12. The movable rod 12 is slidably connected inside the fixed rod 11, allowing for easy adjustment of the extension length of the movable rod 12 according to the user's actual needs, ensuring that the fixed plate 7 can contact the ground. The fixed rod 11 has a second threaded hole 13, and a bolt 14 is threaded into the second threaded hole 13. One end of bolt 14 abuts against moving rod 12. By adjusting the position of moving rod 12 and locking it with bolt 14, the telescopic rod 5 is kept stable during use. The bottom end of telescopic rod 5 is connected to the second hinge seat 6, realizing the rotational connection between telescopic rod 5 and fixed plate 7. Users can flexibly adjust the angle of telescopic rod 5 according to the actual ground conditions to ensure that fixed plate 7 can be in close contact with the ground, thereby providing stable support. Fixed plate 7 is provided on one side of the second hinge seat 6. Fixed plate 7 is used to fix anchor rod 9. By tightening anchor rod 9, the ladder can be fixed to the ground, increasing stability. Fixed plate 7 is provided with first threaded hole 8. An anchor rod 9 is threaded inside the first threaded hole 8. Anchor rod 9 can be manually screwed into the ground through rotating plate 10 to provide additional stable support for the ladder and prevent the ladder from sliding or tipping over during operation. The top end of anchor rod 9 is connected to rotating plate 10, which makes it easier for users to manually rotate anchor rod 9, making it easier to insert into hard ground or soft soil, improving installation efficiency and ease of use.

[0029] like Figures 1-4As shown, one of the columns 1 is connected to one side with two connecting rods 15. The two connecting rods 15 are located at the top and bottom of the column 1 respectively, forming an auxiliary connection structure between the two columns 1. They provide lateral support and positioning when the ladder is unfolded. A connecting plate 16 is fitted onto the outer side of the connecting rod 15, and the connecting plate 16 can rotate around the connecting rod 15. One end of the connecting plate 16 has a through hole 17 to ensure that the connecting plate 16 can be smoothly inserted into the screw 18. The other column 1 is connected to one side with a screw 18, and the through hole 17 matches the screw 18. A nut 19 is threaded onto the connecting plate 16. The nut 19 is located on the outside of the connecting plate 16. Tightening the nut 19 can firmly fix the connecting plate 16 onto the threaded rod 18, thereby stably connecting the left and right uprights 1, enhancing the rigidity of the overall ladder structure, and preventing deformation or shaking caused by external forces. One end of the connecting rod 15 is connected to a limit plate 20, which limits the sliding range of the connecting plate 16 on the connecting rod 15 and prevents it from accidentally falling off. The bottom end of the upright is connected to an anti-slip pad 21, which is made of rubber or other high friction coefficient materials, to increase the friction between the ladder and the ground and prevent slippage.

[0030] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0031] In summary, with the help of the above-mentioned technical solution of this utility model, in actual use, when the ladder needs to be unfolded, the two uprights 1 can be pulled to rotate the first step 2 and the second step 3 around the uprights 1, straightening the first step 2 and the second step 3. Then, by rotating the connecting plate 16, the through hole 17 at one end of the connecting plate 16 is placed outside the screw 18. Then, by passing one end of the connecting plate 16 onto the screw 18, and then by installing the nut 19 on the screw 18, the connecting plate 16 is fixed, thereby achieving a stable connection between the two uprights 1. Then, by tilting the ladder to the outside of the building, the second hinge seat 6 can be brought into contact with the fixed plate 7 and the ground by rotating the telescopic rod 5. Then, the user can rotate the rotating plate 10 to screw the anchor rod 9 into the ground, thereby firmly fixing the ladder to the ground. This fixing method can effectively prevent the ladder from sliding or tipping over during use, ensuring the safety of the user.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
