Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seats, in particular to a ladder chair. Background Art
[0002] With the advancement of technology and the improvement of people's living standards, the requirements for the versatility and convenience of equipment are getting higher and higher. In daily life, work and outdoor activities, people often need to face different usage scenarios. For example, they need a comfortable seat when they need to rest, and a stable ladder when they need to work at height.
[0003] Traditional equipment can often only meet a single need, which not only increases the burden of carrying and storage, but also limits the flexibility and practicality of the equipment. Some existing multifunctional equipment is not flexible enough in shape conversion during use and requires complex operations or tools to complete. In addition, some seats cannot adjust the backrest according to the user's body shape, and the comfort is low. In response to the above problems, the utility model designs a ladder chair. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to provide a ladder chair.
[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0006] A ladder chair includes a support plate and a movable plate, both sides of the support plate are fixedly connected to the first support frame, both sides of the movable plate are fixedly connected to the second support frame, the opposite sides of the two first support frames are fixedly connected to the first mounting seat, the opposite sides of the two second support frames are fixedly connected to the second mounting seat, the opposite sides of the first mounting seat and the second mounting seat are rotatably connected by a hinge, and the upper surfaces of the two second support frames are fixedly connected to the fixing rod.
[0007] As a further improvement of the present invention, the surfaces of the two fixing rods are sleeved with mounting frames, and a backrest board is fixedly connected between the two mounting frames.
[0008] As a further improvement of the present invention, threaded holes are provided on opposite sides of the two fixing rods, and fixing bolts matching the threaded holes are threadedly connected on opposite sides of the two mounting frames.
[0009] As a further improvement of the present invention, a bottom pedal is fixedly connected between the two first support frames.
[0010] As a further improvement of the present invention, two top pedals are fixedly connected between the two second support frames.
[0011] As a further improvement of the present invention, the two first support frames are rotatably connected to opposite sides with a rotating rod, and a seat plate is fixedly connected between the two rotating rods.
[0012] Beneficial effects of the utility model:
[0013] By setting up a first support frame and a second support frame, the device can be quickly switched into a seat or a ladder according to different usage requirements, which greatly improves space utilization and the practicality of the equipment. Whether it is outdoor camping, home repairs or temporary workplaces, it can be easily coped with, reducing the trouble of carrying multiple tools or equipment. The form conversion can be achieved through simple operations without the need for complicated installation steps or tools. Users can quickly complete the conversion process, which improves work efficiency and reduces the cost of purchasing and storing multiple devices. It is especially suitable for users who need to frequently change usage scenarios.
[0014] By setting up a fixed rod, in ladder mode, the second support frame contacts the ground through the hinge and the fixed rod to form a stable support structure, ensuring safety during use. At the same time, the design of the bottom pedal and the top pedal provides climbers with sufficient footing and support points to prevent slipping or falling, thereby increasing the safety of the device.
[0015] By setting up an adjustment mechanism, the seat backrest can be adjusted in height according to the user's body shape and fixed with fixing bolts to ensure the comfort and stability of the seat. This personalized adjustment design allows people of different heights and body shapes to find the sitting posture that suits them best.
[0016] In summary, the multifunctional conversion device of the present invention provides users with a more flexible, efficient and comfortable use experience with its advantages of versatility, convenience, adjustability, stability and safety, cost savings, and environmental protection and energy saving.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0023] Reference Figures 1-4 A ladder chair comprises a support plate 1 and a movable plate 2, both sides of the support plate 1 are fixedly connected to the first support frame 3, both sides of the movable plate 2 are fixedly connected to the second support frame 4, the opposite sides of the two first support frames 3 are fixedly connected to the first mounting seat 5, the opposite sides of the two second support frames 4 are fixedly connected to the second mounting seat 6, the first mounting seat 5 and the second mounting seat 6 are rotatably connected on the opposite sides through a hinge 7, the upper surfaces of the two second support frames 4 are fixedly connected to the fixing rods 8, and the surfaces of the two fixing rods 8 are sleeved with adjustment mechanisms.
[0024] In the present utility model, the adjustment mechanism includes a mounting frame 9 sleeved on the surface of the two fixing rods 8, a backrest plate 10 is fixedly connected between the two mounting frames 9, threaded holes 11 are provided on the opposite sides of the two fixing rods 8, and fixing bolts 12 that are compatible with the threaded holes 11 are threadedly connected on the opposite sides of the two mounting frames 9. The height of the backrest plate 10 is adjusted by setting the mounting frame 9 and the fixing bolts 12.
[0025] A bottom pedal 13 is fixedly connected between the two first support frames 3, two top pedals 14 are fixedly connected between the two second support frames 4, and a rotating rod 15 is rotatably connected to the opposite sides of the two first support frames 3. A seat board 16 is fixedly connected between the two rotating rods 15. The arrangement of the bottom pedal 13 and the top pedal 14 provides users with sufficient footing points and support points to prevent slipping or falling.
[0026] When the present invention is in use, the device is switched into different forms according to different usage scenarios. When a seat is needed, the support plate 1 and the movable plate 2 are placed in the same plane through the hinge 7, and the seat plate 16 is rotated to above the support plate 1 and the movable plate 2 through the rotating rod 15. At the same time, the backrest plate 10 is moved to a suitable height through the mounting frame 9 according to the body shape of the user. After the movement is completed, the mounting frame 9 is fixed to the fixing rod 8 using the fixing bolt 12, so that the backrest plate 10 is installed to a suitable height.
[0027] When a ladder is needed, the seat plate 16 is first flipped to the front of the first support frame 3 through the rotating rod 15, and then the second support frame 4 is rotated to the top of the first support frame 3 through the second mounting seat 6 and the hinge 7. After complete flipping, the movable plate 2 will be located above the support plate 1, and the fixed rod 8 will contact the ground to support the second support frame 4. The user climbs up through the bottom pedal 13, the support plate 1, the movable plate 2 and the top pedal 14.
[0028] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
