Description

Technical Field

[0001] The utility model belongs to the technical field of decoration construction equipment, and particularly relates to a double-ladder for indoor and outdoor decoration. Background Technique

[0002] The double-ladder is an indispensable type of登高 tool for indoor and outdoor decoration. When in use, the front and rear ladder bars and the ground form an isosceles triangle, and its shape is similar to the Chinese character "人", so it gets this name. In the early days, most double-ladders were made of wood. With the development of the metal industry, aluminum alloy materials have become the current mainstream choice due to their advantages of light weight, beauty, durability, and moderate cost. In indoor decoration operations, especially in occasions where the use of scissor lifts or scaffolding is inconvenient due to height restrictions, the double-ladder plays an irreplaceable role, and its stability directly relates to the efficiency and safety of construction workers.

[0003] There are still many problems to be solved urgently in the actual use of the existing double-ladders. Most double-ladders do not have a convenient tool storage and artificial standing platform. When workers need to frequently change tools, they need to climb up and down the ladder many times, which not only increases the labor intensity but also brings additional safety hazards. The double-ladders with a platform structure have a large volume after being stored, which is not convenient for handling and storage. Content of the Utility Model

[0004] In view of the above-mentioned disadvantages of the existing technology, the purpose of the utility model is to provide a double-ladder for indoor and outdoor decoration, which is used to solve the problem that the existing double-ladder does not provide an operating platform structure in time.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: The utility model includes a main ladder, a support rotating shaft, an operating platform board, and support feet. The support rotating shaft is rotatably arranged at the top end of the main ladder. There are two support feet, and the top ends of the two support feet are rotatably connected to both ends of the support rotating shaft and are located on both sides of the top end of the main ladder. One edge of the operating platform board is rotatably arranged on the support rotating shaft and is located in the middle of the top end of the main ladder.

[0006] Optionally, it further includes a support rod. The bottom end of the support rod is hinged to the inner side of the bottom end of the support foot. A card slot is opened inward on the side surface of the upper end of the support rod. A pin rod is fixedly arranged on the side surface of the free end of the operating platform board. When the double-ladder is unfolded and laid flat, rotate the operating platform board to keep it horizontal, and the pin rod is stuck into the card slot to make the support rod support the operating platform board.

[0007] Optionally, there are multiple fixed connecting rods. There are two support rods, and they are respectively hinged to the two support feet. Both ends of the fixed connecting rod are fixedly connected to the support rod respectively.

[0008] Optionally, a stop pin is slidably provided at the upper end of the support rod, the stop pin passing through the slot and blocking the pin rod that is locked into the slot.

[0009] Optionally, the middle section of the stop pin is provided with a stop ring, and the upper end of the support rod is provided with an inner groove for the stop ring to slide. A spring is provided between the inner groove and the stop ring. The upper end of the stop pin passes through the upper end of the support rod. Pulling the stop pin from the upper end of the support rod moves the stop pin away from the slot. When the stop pin is released, the spring supports the stop pin to spring back into the slot.

[0010] Optionally, the surface of the operating platform is provided with a number of anti-slip ridges.

[0011] Optionally, the support rod includes a lower rod and an upper rod. The slot is disposed at the upper end of the upper rod, and the lower end of the upper rod is slidably disposed at the end of the lower rod. A plurality of pin holes are arranged along the side of the upper rod, and an elastic locking pin is provided on the side of the lower rod. The elastic locking pin is engaged in the pin holes to fix the distance between the upper rod and the lower rod.

[0012] Optionally, it also includes a pull rod, the two ends of which are simultaneously slidably mounted on the two lower rods. One side of the pull rod contacts the surface of the lower rod where a pin hole is opened. The protruding part of the elastic locking pin from the lower rod is hemispherical. The pull rod moves along the lower rod and presses down on the elastic locking pin, causing the elastic locking pin to move inward toward the upper rod.

[0013] The beneficial effects of this utility model are as follows: The A-frame ladder, with its operating platform, not only provides a comfortable working platform and reduces fatigue from long-term high-altitude work, but its storage function also makes the workflow more coherent and efficient. It is particularly suitable for use in indoor and outdoor decoration scenarios with changing environments, effectively solving the shortcomings of traditional A-frame ladders in terms of mobility, adaptability, and comfort during long-term work.

[0018] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0019] This utility model provides a stepladder for indoor and outdoor decoration, such as... Figure 1 As shown, it includes a main ladder 1, a support shaft 2, an operating platform 3, and support legs 4. The support shaft 2 is rotatably mounted on the top of the main ladder 1. There are two support legs 4, and the top ends of the two support legs 4 are rotatably connected to the two ends of the support shaft 2 and located on both sides of the top of the main ladder 1. One edge of the operating platform 3 is rotatably mounted on the support shaft 2 and located in the middle of the top of the main ladder 1.

[0020] In this structure, the supporting pivot 2 is rotatably mounted at the top of the main ladder 1, and the operating platform 3 is mounted at the top of the main ladder 1 via the supporting pivot 2. During short-term renovation work, the A-frame ladder is used for climbing. During long-term renovation work, the operating platform 3 can serve as a temporary work platform or a seated resting place for workers working at heights, making it convenient to place tools and materials and avoiding the inconvenience of frequently climbing up and down the ladder to retrieve items. This improves work efficiency and reduces labor intensity. The main ladder 1, the operating platform 3, and the supporting legs 4 can be rotated and overlapped together, facilitating the storage and transportation of the A-frame ladder.

[0021] The A-frame ladder with its operating platform 3 not only provides a comfortable working platform and reduces fatigue from long-term high-altitude work, but its storage function also makes the workflow more coherent and efficient. It is particularly suitable for use in indoor and outdoor decoration scenarios with changing environments, effectively solving the shortcomings of traditional A-frame ladders in terms of mobility, adaptability, and comfort during long-term work.

[0022] In further proposals, such as Figure 1 As shown, it also includes a support rod 5, the bottom end of which is hinged to the inner side of the bottom end of the support foot 4. The upper side of the support rod 5 has an inwardly opening groove 511. The free end side of the operating platform 3 is fixedly provided with a pin 32. When the A-frame ladder is unfolded and laid flat, the operating platform 3 is rotated to keep it horizontal, and the pin 32 is engaged in the groove 511, so that the support rod 5 supports the operating platform 3.

[0023] By setting up the support rod 5, the slot 511 of the support rod 5 can support the horizontally placed operating platform 3, so that the support foot 4, the support rod 5 and the operating platform 3 form a stable triangular support. Furthermore, by rotating, the support rod 5 can also overlap with the support foot 4 and the main ladder 1 when storing the A-frame ladder, which is convenient for handling and storage.

[0024] In further proposals, such as Figure 1 As shown, it also includes a fixed connecting rod 6, which has multiple fixed connecting rods. There are two support rods 5, which are respectively hinged to the two support legs 4. The two ends of the fixed connecting rod 6 are respectively fixedly connected to the support rods 5.

[0025] By setting two support rods 5, the operating platform 3 is provided with more stable multi-point support, and the support rods 5 are connected by a fixed connecting rod 6, so that the two support rods 5 can rotate synchronously and bear force from each other.

[0026] In further proposals, such as Figure 1 and Figure 2 The upper end of the support rod 5 is provided with a stop pin 512, which passes through the slot 511 and blocks the pin 32 that is stuck in the slot 511.

[0027] By setting pin 32, when the support rod 5 supports the operating platform 3, the stop pin 512 blocks pin 32, preventing the support rod 5 and the operating platform 3 from separating during construction shaking.

[0028] In further proposals, such as Figure 2 As shown, a retaining ring 513 is provided in the middle section of the retaining pin 512. An inner groove 515 for sliding of the retaining ring 513 is opened inside the upper end of the support rod 5. A spring 514 is supported between the inner groove 515 and the retaining ring 513. The upper end of the retaining pin 512 passes through the upper end of the support rod 5. Pulling the retaining pin 512 from the upper end of the support rod 5 makes the retaining pin 512 move away from the slot 511. When the retaining pin 512 is released, the spring 514 supports the retaining pin 512 to spring back into the slot 511.

[0029] By setting a spring-loaded stop pin 512, the stop pin 512 can be quickly returned to its original position and the stop pin 512 lever 32 can be positioned.

[0030] In a further proposed solution, refer to Figure 1 The surface of the operating platform 3 is provided with several anti-slip ridges 31.

[0031] In further proposals, such as Figure 1 and Figure 2 As shown, the support rod 5 includes a lower rod 52 and an upper rod 51. The slot 511 is provided at the upper end of the upper rod 51. The lower end of the upper rod 51 is slidably disposed at the end of the lower rod 52. A plurality of pin holes 521 are arranged along the side of the upper rod 51. The side of the lower rod 52 is provided with an elastic locking pin 516. The elastic locking pin 516 is engaged in the pin holes 521 to fix the distance between the upper rod 51 and the lower rod 52.

[0032] The structure of the adjustable support rod 5 provides different angles for the support platform 3, so that the A-frame ladder can still be adjusted to a horizontal position when supported on an inclined ground, which is convenient for placing construction materials and for the operator to stand.

[0033] In further proposals, such as Figure 1 and Figure 2 As shown, it also includes a pull rod 7, both ends of which are slidably mounted on the two lower rods 52. One side of the pull rod 7 is in contact with the surface of the lower rod 52 where the pin hole 521 is opened. The part of the elastic locking pin 516 protruding from the lower rod 52 is hemispherical. The pull rod 7 moves along the lower rod 52 and presses down the elastic locking pin 516, causing the elastic locking pin 516 to move inward toward the upper rod 51.

[0034] By setting up the pull rod 7, the pull rod 7 synchronously presses down the hemispherical elastic pin 516. After being pressed down, the elastic stop pin 512 sinks into the lower rod 52, which facilitates the adjustment of the misalignment between the upper rod 51 and the lower rod 52. The lower rod 52 can press down the hemispherical elastic pin 516 to provide a structure for quick adjustment of the two support rods 5. When the pull rod 7 moves the elastic pin 516 down, the upper rod 51 and the lower rod 52 are supported by the cylindrical position of the elastic pin 516, which provides stable support and prevents misalignment.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
