Description

Technical Field

[0001] This utility model relates to the field of ladder technology, specifically to an adjustable ladder for decorative engineering. Background Technology

[0002] Decoration engineering refers to the processes involved in building construction, including plastering, painting, grouting, glassing, wallpapering, finishing, paneling, and decorative elements. It is the final construction process in building construction, specifically involving the plastering of interior and exterior walls and ceilings. The purpose of decoration engineering is to protect various building components from natural wind, rain, and moisture erosion, improve heat insulation, sound insulation, and moisture resistance, enhance the durability of the building, and extend its service life. Utility model patent CN220267574U discloses a retractable decorative ladder for decoration engineering. This device, through the action of a base pad and an anti-slip pad, achieves a supporting and anti-slip effect when the ladder is extended. When the ladder is extended, the first and second connecting rods are rotatably connected to the base pad on their circumferences, and the lower end of the base pad is fixed with an anti-slip pad, thus improving the stability of the ladder when extended. However, this device has a large length when the ladder is retracted, making it inconvenient for storage and transportation, and its versatility is poor. Utility Model Content

[0003] The purpose of this utility model is to provide an adjustable ladder for decorative engineering. This ladder has a large extension range, which makes it easy to store and transport. It can be flipped to a straight state to extend the climbing height and has good overall stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adjustable ladder for decorative engineering includes two movable ladder units, each ladder unit comprising an adjustable multi-stage telescopic column and foot pedals; the ladder units are adjustablely mounted on a ladder frame; the tops of the two ladder units are hinged to a flip assembly, and the two ladder units can be flattened into a straight state; a connecting groove is provided on the side of the ladder frame.

[0006] Preferably, a connector is installed at the bottom inner side of the ladder frame, and control ropes are installed on the two connectors that are arranged opposite to each other.

[0007] Preferably, the multi-stage telescopic column includes a first-stage telescopic column, a second-stage telescopic column, a third-stage telescopic column, a fourth-stage telescopic column that are installed in sequence and adjustable, and a top plate that is fixedly installed on the top of the fourth-stage telescopic column. The top plate is hinged to the bottom of the flipping assembly.

[0008] Preferably, the flipping assembly includes a connecting block and a fixing plate fixedly disposed on both sides of the bottom of the connecting block, with connecting holes provided on the fixing plate, and the top plate being hinged in the connecting holes by a pin.

[0009] Preferably, the top plate is L-shaped.

[0010] Preferably, the ladder frame is L-shaped overall.

[0011] Preferably, a foot pedal is provided on each of the first-level telescopic column, the second-level telescopic column, the third-level telescopic column, and the fourth-level telescopic column.

[0012] In this embodiment, the bamboo-joint telescopic structure design provides a large telescopic ratio, facilitating transport and storage, and offering convenient use. When the control rope is released, the two individual ladder units can be flipped to a straight position, i.e., set 180° opposite each other, extending the climbing height of the ladder and improving versatility. The control rope limits the opening angle of the two individual ladder units, ensuring stability during operation. The ladder frame further adjusts the climbing height, enhancing adjustability.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figures 1-6The adjustable ladder shown includes two movable ladder units 1. Each ladder unit 1 includes an adjustable multi-stage telescopic column and foot pedals 10. In this embodiment, the multi-stage telescopic column includes a first-stage telescopic column 11, a second-stage telescopic column 12, a third-stage telescopic column 13, and a fourth-stage telescopic column 14, which are installed in sequence and adjustablely, and a top plate 15 fixedly installed on the top of the fourth-stage telescopic column 12. A foot pedal 10 is provided on each of the first-stage, second-stage, third-stage, and fourth-stage telescopic columns 11 and 12, 13, and 14. Of course, three-stage, five-stage, or six-stage telescopic columns can also be designed and used as needed. In this embodiment, the ladder unit uses a bamboo-joint telescopic ladder structure available on the market, and its specific structure will not be described in detail here.

[0022] The outer surface of the footboard 10 is covered with an anti-slip layer to improve climbing safety. The top plate 15 is L-shaped. The primary telescopic posts 11, 2nd-level telescopic posts 12, 3rd-level telescopic posts 13, and 4th-level telescopic posts 14 are all made of stainless steel, which has high corrosion resistance and can be used in harsh environments.

[0023] The tops of the two individual ladder units 1 are hinged to the flipping assembly 2, and the top plate 15 is hinged to the bottom of the flipping assembly 2. The two individual ladder units 1 can be flattened into a straight state, which is the ultimate state. At this point, the two individual ladder units 1 are arranged at 180°, forming an extended straight ladder, serving a dual purpose. The flipping assembly 2 includes a connecting block 20 and fixed plates 21 fixedly disposed on both sides of the bottom of the connecting block 20. Connecting holes are provided on the fixed plates 21, and the top plate 15 is hinged to the corresponding connecting holes via pins 22. The connecting block 20 limits the maximum unfolding angle of the two individual ladder units 1 to 180°. Furthermore, to improve the stability of the two individual ladder units 1 in the flattened state, limiting components are installed on the two four-stage telescopic columns 14 to restrict rotation between the top plate 15 and the fixed plate 21.

[0024] The ladder unit 1 is adjustablely mounted on the ladder frame 3; a connecting groove 4 is provided on the side of the ladder frame 3. The ladder frame 3 is generally L-shaped, and the first-stage telescopic column 11 is installed inside the ladder frame 3 and is fixedly installed in an adjustable manner by bolts, further increasing the climbing height.

[0025] In a preferred embodiment, an anti-slip pad 5 is installed at the bottom of the ladder frame 3. The bottom of the anti-slip pad 5 has anti-slip patterns. The anti-slip pad 5 is made of rubber. When used indoors, it can prevent it from scratching the indoor floor. The anti-slip patterns can increase the friction between the ladder and the ground, thereby improving the stability of the entire device.

[0026] Connector 6 is installed on the inner bottom of the ladder frame 3. Control ropes 7 are detachably installed on the two opposite connectors 6. The control ropes 7 can limit the opening angle of the two individual ladder units 1, improving stability during operation. When one end of the control rope 7 is detached from the corresponding connector 6, the two individual ladder units 1 can be flattened into a straight state. Of course, when the ladder is in the retracted state, the control ropes 7 can also be used to tie the two individual ladder units 1 together, serving two purposes. The connectors 6 are connected to the individual ladder units 1 by snap-fit ​​or bolts, making disassembly and assembly convenient and easy to replace.

[0027] The above embodiments are merely illustrative of the concept and implementation of this utility model, and are not intended to limit it. Under the concept of this utility model, the technical solutions without substantial changes are still within the scope of protection.
