Description

Design of novel multifunctional ladder

Technical Field

The utility model belongs to the technical field of engineering equipment, concretely relates to novel ladder and major structure's design thereof.

Background

With the development of times and the progress of science and technology, people put higher requirements on the integration of tools used in daily life and the comprehensiveness of functions, the traditional ladder comprises a straight ladder, an extension ladder, a herringbone ladder and the like, and certain problems always exist in the use process, such as the problem that no space is available for placing tools in the working process; the working environment is not comfortable, and workers need to stand on the ladder for a long time to work up; the stability of the structure of the ladder and the anti-skid performance of the pedal and the base can bring great inconvenience to people in daily life, and workers working on the ladder for a long time can not only be tired but also suffer from cervical spondylosis and other problems. And the utility model discloses above-mentioned problem has been considered and the improvement is carried out to multi-functional ladder in the design process, takes anti-skidding design to seat and footboard department, thereby has increased seat and workstation and has improved staff's operational environment to realize the biggest foldization, make its maximize when non-operating condition save space.

Disclosure of Invention

The utility model relates to a novel structural design of multi-functional ladder, its purpose is for the maximum working condition who improves the ladder user, reduces staff intensity of labour, improves operational environment's security and travelling comfort and convenience when using and the space-saving nature after the use. The ladder of the utility model adopts the design of the foldable seat, the seat backrest can be flexibly controlled, and the angle of the seat backrest can be changed by changing the position of the supporting rod of the seat backrest through the clamping groove in the middle of the main body of the ladder, thereby achieving the purpose of changing the angles of the seat and the backrest; all the pedals and the ground seats are provided with anti-skid lines, and the area of the pedals is larger than that of the traditional ladder pedals, so that the safety and comfort of users are improved.

The structural design of a novel multifunctional ladder comprises the following components: the ladder comprises a ladder frame I (1), a ladder frame II (2), a limiting rod (3), a pedal (4), a ground seat (5), a seat (6), a seat backrest (7), a rod (8) and a workbench (9). The method is characterized in that: a comfortable working position and angle are provided for the user through the adjustment of the supporting part of the backrest of the chair; the safety factor and the comfort level are increased through the design of the anti-skid grains of the pedal and the ground seat; the worktable is additionally arranged in front of the seat, the ergonomics of each structure is considered during design, so that the labor intensity of a user is reduced, and both hands are released, thereby being more beneficial to operation. The utility model has the advantages that:

1. the utility model discloses be provided with the seat in the structure of ladder, if long time work is gone on the ladder, for example whitewash the wall body, circuit or lamps and lanterns etc. are changed in the installation, and the staff can have a rest on the seat, alleviates staff's fatigue.

2. The utility model discloses be equipped with the draw-in groove at the supporting part of seat, lock the support of seat, make the folding seat chair of ladder safer when the expansion state.

3. The utility model discloses be provided with gag lever post (pull rod) with adjustable in the middle of two ladder legs, can change the expansion angle of ladder leg to adapt to different operational environment.

4. The utility model discloses antiskid setting is installed to the ladder, including the anti-skidding line of footboard, and the antiskid seat of ladder bottom, it is big with ground area of contact, coefficient of friction is big, safer.

5. The utility model discloses be provided with the workstation on the ladder, the staff can place the instrument on little workstation in the course of the work, makes the staff more light convenient in the course of the work, avoids the staff to carry the danger that the instrument work brought, also saves staff's physical power simultaneously.

Detailed Description

Referring to fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, a design of a novel multifunctional ladder comprises: the ladder comprises a ladder frame I (1), a ladder frame II (2), a limiting rod (3), a pedal (4), a ground seat (5), a seat (6), a seat backrest (7), a rod (8) and a workbench (9). The method is characterized in that: the foldable design is adopted, so that the ladder is convenient to store when not in use; the foldable seat and the seat backrest are added to provide a comfortable working environment for a user, the user can sit down to carry out work after putting down the seat when climbing to the top, and if the angle of the seat is inconvenient to work, the position of the supporting rod below the seat backrest in the clamping groove can be adjusted, so that the angle of the seat is changed to the optimal position; the workbench is increased, tools can be placed on the workbench during working, both hands can be released, high-speed work tasks can be completed more efficiently, the seat backrest and the workbench can be retracted by folding when the use is completed, the workbench serves as the uppermost end of the ladder, a hand opening is formed when the ladder is convenient to move, and convenience is brought to the moving process of the ladder.

According to the principle of providing a safer working environment for a user, the anti-skid lines are additionally arranged at the pedal and the ground seat, and the large contact area is adopted, so that the user is more comfortable when stepping on the pedal and is fully contacted with the ground, and the stability is improved; the main frames on the two sides respectively adopt two rods for connecting the pedals, so that the pedals cannot turn over, slide down, be unstable and the like when being trampled by a user, and are parallel to each other; the limiting rod is connected between the two ladder main frames to play a good limiting role in improving the safety of a user, and when the limiting rod is completely stretched, namely, in a working state, the limiting rod connecting the pedals is fixed to the working state, namely, the pedals are enabled to be parallel to each other and parallel to the ground.

Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
