Description

Technical Field

[0001] This utility model relates to the field of household ladder technology, specifically a reinforced and deformation-resistant household safety non-slip aluminum ladder. Background Technology

[0002] Household ladders are lightweight, safe, and easy to store, and are used for high-altitude operations such as home cleaning and maintenance. Household ladders are made of various materials, commonly including wood, aluminum alloy, carbon steel, and stainless steel. These material choices give the ladders both anti-slip and wear-resistant properties, and can meet the needs of different home environments. Ladders made of aluminum are favored by many families because of their lightweight and corrosion resistance.

[0003] For example, patent CN209838262U discloses a user-friendly household ladder, including ladder steps, with force-bearing bars movably installed on both sides of the ladder steps, and folding bars movably installed on both sides of the ladder steps behind the force-bearing bars. Support bars are movably installed on the surface of the force-bearing bars near the upper end, and stabilizing brackets are movably installed on one side of the force-bearing bars and the support bars near the lower end. Casters are movably installed on the rear surface of the support bars. This household ladder can prevent users from slipping and falling when leaning to the sides of the ladder, thus providing good stability. However, some existing household ladders have limited step load-bearing capacity. If heavy objects are carried while climbing the ladder, the overall weight on the ladder increases, and local parts of the ladder steps are prone to deformation, which is not conducive to the subsequent folding and storage of the ladder and also affects the safety of subsequent use. In addition, the smooth surface of the steps of some existing ladders makes it easy to slip during climbing, which also affects the safety of use.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing household ladders. Utility Model Content

[0005] The purpose of this utility model is to provide a reinforced and deformation-resistant household safety anti-slip aluminum ladder to solve the problems mentioned in the background art, such as the limited load-bearing capacity of the steps of some existing household ladders, the increased overall weight of the ladder when carrying heavy objects while climbing the ladder, the deformation of the ladder steps in some places, which is not conducive to the subsequent folding and storage of the ladder, and also affects the safety of the ladder in subsequent use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reinforced and deformation-resistant household safety anti-slip aluminum ladder, comprising two sets of uprights, one set of uprights having a main rotating rod fixed to its upper end, and the other set of uprights having a secondary rotating rod fixed to its upper end, with the main rotating rod and the secondary rotating rod rotatably connected. An anti-slip base is fixedly installed on the lower end face of the uprights. A first support rod is rotatably connected to the side of one upright, and a second support rod is rotatably connected to the side of the other upright, with the first support rod and the second support rod rotatably connected. Multiple step groups are fixed at equal intervals on the uprights, and the step groups are provided with a reinforced and deformation-resistant support mechanism.

[0007] Preferably, the step assembly includes a step beam fixed on the upright, and step side plates are symmetrically fixed on both sides of the step beam; a triangular bracket is fixedly installed at the right angle where the step beam and the step side plates are combined.

[0008] Preferably, the support mechanism includes a reinforcing rod fixed to the lower end face of the step side plate, and multiple lateral sliding grooves are equally spaced on both sides of the step crossbeam, with lateral sliders slidably connected in the lateral sliding grooves, and a support rotating rod connecting the lateral sliders and the reinforcing rod.

[0009] Preferably, the support rod is inclinedly disposed between the lateral slider and the reinforcing rod, one end of the support rod is rotatably connected to the lateral slider, and the other end of the support rod is rotatably connected to the reinforcing rod; a fixed crossbar is installed between the multiple lateral sliders that are distributed laterally at equal intervals.

[0010] Preferably, the step beam has multiple recessed slots at equal intervals, and a drive ball seat is slidably connected in the recessed slots. The drive ball seat is fixedly connected to the lateral slider.

[0011] Preferably, a disc is fixedly installed at the bottom of the embedded groove, and a round rod is coaxially fixed on the disc, with the drive ball seat slidably sleeved on the outside of the round rod; a limit spring is elastically connected between the drive ball seat and the disc.

[0012] Preferably, the step assembly is equipped with an anti-slip mechanism to improve the safety of climbing the ladder.

[0013] Preferably, the anti-slip mechanism includes longitudinal anti-slip grooves evenly spaced on the upper surface of the step beam, and multiple transverse anti-slip grooves evenly spaced on the upper surface of the step beam, with the transverse anti-slip grooves positioned between two adjacent longitudinal anti-slip grooves; multiple inclined grooves evenly spaced on the upper surface of the step side plate; and multiple annular transverse grooves evenly spaced on the outside of the drive ball seat.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the reinforced and deformation-resistant household safety anti-slip aluminum ladder consists of a step assembly composed of a step beam and two sets of step side plates, which expands the width of the steps and the step assembly has a strong load-bearing capacity and is not prone to deformation.

[0015] Furthermore, the step assembly is equipped with a support mechanism. A reinforcing rod is fixed to the bottom of the step side plate, and a support rotating rod is inclined to support the side of the reinforcing rod. The rotation of the support rotating rod provides an upward support force to the reinforcing rod, thereby supporting and reinforcing the step side plate and preventing the step assembly from deforming under stress.

[0016] When a user climbs and steps on the step assembly, the drive ball joint moves downward under pressure, causing the lateral slider to move downward in sync. This causes the two ends of the support rod connected between the lateral slider and the reinforcing rod to rotate, thereby providing upward support force to the reinforcing rod.

[0017] Furthermore, the step assembly is equipped with an anti-slip mechanism. Vertically distributed longitudinal and transverse anti-slip grooves are provided on the step crossbeam, and inclined grooves are provided on the step side plate. The anti-slip effect of the step assembly can be increased through different groove structures.

[0018] The drive ball seat has multiple annular horizontal grooves, the direction of which is perpendicular to the direction of the longitudinal anti-slip grooves, further increasing the anti-slip performance when users climb the household ladder. Attached Figure Description

Detailed Implementation

[0028] 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.

[0029] Example 1: Please refer to Figures 1-8 This utility model provides the following technical solution: a reinforced and deformation-resistant household safety anti-slip aluminum ladder, comprising two sets of uprights 1, one set of uprights 1 with a main rotating rod 2 fixed at the upper end, and the other set of uprights 1 with a secondary rotating rod 3 fixed at the upper end, and the main rotating rod 2 and the secondary rotating rod 3 are rotatably connected. An anti-slip base 4 is fixedly installed on the lower end face of the uprights 1. A first support rod 5 is rotatably connected to the side of one upright 1, and a second support rod 6 is rotatably connected to the side of the other upright 1, and the first support rod 5 and the second support rod 6 are rotatably connected. Multiple step groups 7 are fixed at equal intervals on the uprights 1, and a reinforced and deformation-resistant support mechanism is provided on the step groups 7.

[0030] The step assembly 7 includes a step beam 71 fixed on the upright 1, and step side plates 72 are symmetrically fixed on both sides of the step beam 71; a triangular bracket 73 is fixedly installed at the right angle where the step beam 71 and the step side plates 72 are combined.

[0031] The support mechanism includes a reinforcing rod 8 fixed to the lower end face of the step side plate 72. Multiple lateral sliding grooves 9 are equally spaced on both sides of the step crossbeam 71, and lateral sliders 10 are slidably connected in the lateral sliding grooves 9. A support rotating rod 11 is connected between the lateral sliders 10 and the reinforcing rod 8.

[0032] The support rod 11 is inclinedly disposed between the lateral slider 10 and the reinforcing rod 8. One end of the support rod 11 is rotatably connected to the lateral slider 10, and the other end of the support rod 11 is rotatably connected to the reinforcing rod 8. A fixed crossbar 12 is installed between multiple lateral sliders 10 that are distributed laterally at equal intervals.

[0033] The step beam 71 has multiple recessed grooves 13 at equal intervals, and a drive ball seat 14 is slidably connected in the recessed groove 13. The drive ball seat 14 is fixedly connected to the side slider 10.

[0034] A disc 15 is fixedly installed at the bottom of the recessed groove 13, and a round rod 16 is coaxially fixed on the disc 15. The drive ball seat 14 is slidably sleeved on the outside of the round rod 16. A limit spring 17 is elastically connected between the drive ball seat 14 and the disc 15.

[0035] When using the ladder, control the corresponding rotation between the main rotating rod 2 and the auxiliary rotating rod 3, the two sets of uprights 1 rotate and unfold, and the first support rod 5 and the second support rod 6 connected between the two sets of uprights 1 rotate and unfold. Rotate the first support rod 5 and the second support rod 6 to a horizontal state, at which point the ladder will be fully rotated and unfolded.

[0036] When climbing the ladder, the user's feet step on the step assembly 7, which is formed by the combination of the step beam 71 and two step side plates 72, increasing the width of the steps and making climbing more stable and safer. The drive ball seat 14 in the step beam 71 protrudes from the surface of the step beam 71. When the user's feet step on the step beam 71, they contact the drive ball seat 14, providing downward pressure to the drive ball seat 14, causing the drive ball seat 14 to move downward in the inner groove 13. The downward pressing of the limiting spring 17 drives the ball seat 14 to move downward, causing the lateral sliders 10 on both sides to engage in the lateral slide groove 9 and move downward synchronously. The support rod 11 connected between the lateral slider 10 and the reinforcing rod 8 rotates accordingly. The rotating support rod 11 provides an upward thrust to the reinforcing rod 8. The reinforcing rod 8 is supported and set below the step side plate 72, which improves the load-bearing capacity of the step side plate 72 during climbing and prevents the step side plate 72 from deforming under heavy pressure.

[0037] Example 2: Based on Example 1, an anti-slip mechanism is also disclosed, the specific structure of which is as follows: An anti-slip mechanism to improve climbing safety is provided on the step assembly 7; the anti-slip mechanism includes longitudinal anti-slip grooves 18 evenly spaced on the upper surface of the step beam 71, and multiple transverse anti-slip grooves 19 evenly spaced on the upper surface of the step beam 71, the transverse anti-slip grooves 19 being disposed between two adjacent longitudinal anti-slip grooves 18; multiple inclined grooves 20 evenly spaced on the upper surface of the step side plate 72; and multiple annular transverse grooves 21 evenly spaced on the outside of the drive ball seat 14.

[0038] During the climbing and stepping process, the longitudinal anti-slip grooves 18 and transverse anti-slip grooves 19 on the surface of the step beam 71 are vertically distributed, and the inclined grooves 20 on the surface of the step side plate 72 are obliquely set on both sides of the longitudinal anti-slip grooves 18. The inclined grooves 20 on the surface of the step side plate 72 on both sides of the step beam 71 are symmetrically distributed. Through the setting of the longitudinal anti-slip grooves 18, transverse anti-slip grooves 19 and inclined grooves 20, the friction of stepping on the surface of the step assembly 7 can be effectively improved, thereby improving the anti-slip effect of the ladder climbing application. At the same time, the outer surface of the drive ball seat 14 is provided with an annular transverse groove 21. The opening direction of the annular transverse groove 21 is perpendicular to the opening direction of the longitudinal anti-slip groove 18, which can further improve the friction effect of stepping on the surface of the step assembly 7 and increase the safety of the ladder.
