Description

Technical Field

[0001] The present application relates to the field of herringbone ladder equipment, and in particular to a single-sided working ladder. Background Art

[0002] A-type ladder, also known as A-type ladder, folding ladder or telescopic ladder, is a common climbing tool, widely used in homes, factories, construction sites and other places. It is named because its shape after unfolding resembles the letter "A". The design of the herringbone ladder is easy to carry and store, and it can provide a certain height of support while ensuring safety.

[0003] At present, there are single-sided work ladders on the market based on the herringbone ladder. Single-sided work ladders usually have only one side for climbing, and the other side is fixed to the ground or a structure. Compared with the herringbone ladder, the single-sided work ladder is safer.

[0004] However, due to the staggered settings on both sides or different specifications on both sides of the existing single-sided work ladder, when the operator folds and lifts the single-sided work ladder, the two sides of the single-sided work ladder tend to be parallel, causing the single-sided work ladder to deform and affect subsequent use, posing certain safety hazards.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a single-sided working ladder. Figure 1 The single-sided working ladder includes a top plate 1, a climbing frame 2, a supporting frame 3, a limit block 4 and a swing rod assembly 5. One end of the climbing frame 2 is fixedly connected to the bottom of the top plate 1, and the supporting frame 3 is arranged opposite to the climbing frame 2. One end of the supporting frame 3 is hinged to the bottom of the top plate 1. The supporting frame 3 can have an unfolded state or a folded state when rotating on the top plate 1.

[0036] like Figure 1 and Figure 2 As shown, one side of the top plate 1 is connected to the climbing frame 2 and the supporting frame 3. When the operator uses the single-sided work ladder, he can stand on the top plate 1 to work in a safe manner, thereby increasing the effective relative height of the single-sided work ladder, thereby increasing the scope of application of the single-sided work ladder and improving the versatility of the single-sided work ladder.

[0037] It should be noted that the top plate 1 needs to be set according to the actual situation. In the embodiment of the present application, a tool slot 11 is provided on the top plate 1. A grid 12 for increasing the friction of the working slot is provided at the bottom of the tool slot 11. A through hole 13 for inserting a tool and a material tray 14 for holding objects are provided in the tool slot 11. There are a plurality of through holes 13, and the diameters and shapes of the plurality of through holes 13 are different. The number of through holes 13 is determined according to the actual use situation, and will not be specifically described in this embodiment; the material tray 14 is provided in the middle of the tool slot 11, and the through holes 13 are staggered from the material tray 14.

[0038] like Figure 3 and Figure 4 As shown, the climbing frame 2 includes a vertical pole 21 and a pedal 22, both of which are hollow shell structures. Two vertical poles 21 are provided, one end of the two vertical poles 21 is fixedly connected to the bottom of the top plate 1, and the other ends of the two vertical poles 21 are sleeved with ladder feet for anti-slip, so as to reduce the sliding of the climbing frame 2 on the ground when the operators use the single-sided work ladder; a plurality of pedals 22 are provided, and a plurality of pedals 22 are arranged on the vertical pole 21 perpendicular to the axis of the vertical pole 21 for the operators to step on, and both sides of the plurality of pedals 22 are bent inwardly to form a bending portion. When the single-sided work ladder needs to be moved or stored, the bending portion 23 can fit the palm of the operator, so that the operator can effectively hold the pedal 22, thereby improving the efficiency of the operator in moving or storing the single-sided work ladder.

[0039] like Figure 5As shown, the limit block 4 is arranged on the side of the climbing frame 2 close to the support frame 3 and opposite to the support frame 3. The limit block 4 includes a connecting portion 41 and an abutting portion 42. The connecting portion 41 is specifically a metal block. One end of the connecting portion 41 is fixedly connected to the side of the bent portion of the pedal 22 close to the support frame 3, providing a stable support point for the limit block 4 to limit the position of the support frame 3, preventing unnecessary movement and deformation of the support frame 3, thereby ensuring the stability of the support structure of the single-sided working ladder.

[0040] The abutment portion 42 is made of a flexible material such as rubber or plastic. The abutment portion 42 is sleeved on the outer wall of the connecting portion 41 and has an interference fit with the connecting portion 41. The abutment portion 42 is used to contact the support frame 3 in the folded state, so that the limit block 4, the support frame 3 and the climbing frame 2 form a stable whole, further preventing unnecessary movement and deformation of the support frame 3, so that the working ladder can maintain a stable structure in the folded state, further ensuring the stability of the supporting structure of the single-sided working ladder, thereby further improving the problem that the existing single-sided working ladder is easy to deform when folded and lifted, and extending the service life of the single-sided working ladder.

[0041] like Figure 3 As shown, the support frame 3 includes a support rod 31 and a cross rod 32. One end of the support rod 31 is hinged to the vertical rod 21 by being hinged to the bottom of the top plate 1. A plurality of cross rods 32 are arranged along the length direction of the support rod 31. The plurality of cross rods 32 are perpendicular to the axis of the support rod 31, thereby forming a support frame 3 for supporting the climbing frame 2 so that the working ladder has an unfolded working state and a folded storage state, thereby improving the convenience of using the working ladder.

[0042] The corresponding cross bar 32 is staggered with the corresponding pedal 22. Specifically, the corresponding cross bar 32 is staggered with the corresponding limit block 4 on the pedal 22. When the single-sided work ladder is in a folded state, one side of the support rod 3 abuts against the corresponding limit block 4, thereby supporting the support rod 31 when the operator places and moves the single-sided work ladder horizontally, ensuring the tight connection between the climbing frame 2 and the supporting frame 3 in the folded state.

[0043] Specifically, refer to Figure 6 When the single-sided work ladder is in a folded state, one side of the cross bar 32 abuts against the corresponding limit block 4, which avoids the phenomenon that when the operator folds and lifts the single-sided work ladder, the climbing frame 2 and the supporting frame 3 are subjected to uneven force due to the misaligned setting of the two sides of the single-sided work ladder or the different specifications of the two sides, thereby causing the single-sided work ladder to be deformed. This reduces the occurrence of changes in the supporting structure of the single-sided work ladder, and improves the problem that the existing single-sided work ladder is easily deformed when it is folded and lifted.

[0044] like Figure 4As shown, the swing rod assembly 5 includes a first swing rod 51, a second swing rod 52 and a linkage rod 53, one end of the first swing rod 51 is hinged to the climbing frame 2, one end of the first swing rod 51 away from the climbing frame 2 is hinged to one end of the linkage rod 53, one end of the linkage rod 53 away from the first swing rod 51 is hinged to one end of the second swing rod 52, and one end of the second swing rod 52 away from the linkage rod 53 is hinged to the support frame 3.

[0045] Specifically, refer to Figure 3 and Figure 4 When in the unfolded state, the first swing rod 51 and the second swing rod 52 of the linkage rod 53 are arranged in a straight line, so that the swing rod assembly 5 and the climbing frame 2 and the supporting frame 3 form a triangular structure, thereby improving the structural strength of the working ladder and ensuring the structural stability of the single-sided working ladder when the operator is working.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
