Description

Technical Field

[0001] This utility model relates to the field of climbing ladder technology, and in particular to a magnetically-based telescopic climbing ladder. Background Technology

[0002] Currently, when working in environments such as at sea, if workers want to climb from a speedboat (or small boat) to a large ship, they usually need to use the large ship's pilot ladder to climb onto the ship. However, when using such ladders to climb, if there are waves, the ship will rock and roll up and down, making the climb unstable and easily leading to the risk of falling. When the large ship does not lower the ladder, it is difficult for workers on small boats to climb onto the large ship. At the same time, due to the ship's rolling, workers cannot use traditional telescopic ladders to climb, making climbing large ships inconvenient and posing significant safety hazards. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a magnetic climbing telescopic ladder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A magnetic climbing telescopic ladder includes multiple telescopic rods and steps fixed to the telescopic rods. The steps are provided with magnetic bases for magnetic fixation, and magnetic feet are rotatably sleeved on the telescopic rods. A magnet for magnetic fixation is installed at one end of each magnetic foot.

[0005] Preferably, the magnetic feet are arranged one-to-one on the telescopic rod, and each magnetic foot includes a hollow sleeve, with the magnet disposed inside the sleeve and capable of sliding outward under drive.

[0006] Preferably, a drive pin is fixed on the magnet, penetrating the sleeve, and the drive pin drives the magnet to slide.

[0007] Preferably, the sleeve has a groove for the forward and backward displacement of the drive pin, and the drive pin passes through the groove and extends outward.

[0008] Preferably, a wrench is rotatably mounted on the sleeve, and the wrench is hinged to the transmission pin via a sliding plate.

[0009] Preferably, the magnetic base includes a magnetic block for magnetic fixation.

[0010] Preferably, the magnetic base is fixedly connected to the step via a connecting rod.

[0011] Preferably, the magnetic base is equipped with a puller, and the puller is equipped with a support foot.

[0012] Preferably, the telescopic rod and the ladder steps are made of aluminum alloy.

[0013] The beneficial effects of this utility model are: 1. The magnetic base provides the main magnetic support for the magnetic fixation to the boat body, and the magnetic feet on the telescopic pole provide multiple stable magnetic support points for climbing, thereby ensuring the stability and safety of climbing. At the same time, the modular design of the telescopic pole, ladder and magnetic feet allows for quick telescopic assembly and is suitable for climbing boats of different heights, greatly improving the convenience of climbing. 2. A wrench is installed on the sleeve of the magnetic foot. By rotating the wrench, the magnet inside the sleeve is driven to slide outward and magnetically fix it to the hull. When it needs to be stored, the wrench can be rotated in the opposite direction to make the magnet slide back into the sleeve, which facilitates the disassembly of the magnetic foot. After the two magnetic feet of the same height are rotated and stored, the magnets between the two magnetic feet can generate a small magnetic force, so that the magnetic feet can maintain a magnetically attracted storage state for subsequent storage and transportation. 3. By installing a puller on the magnetic base, the magnetic block on the magnetic base can be gradually moved away from the magnetic hull by twisting the support foot on the puller. This allows for quick and easy removal of the magnetic base. By twisting the support foot in the opposite direction, the magnetic base can be gradually magnetically fixed to the hull, thus improving the efficiency of disassembly and installation of the magnetic base.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: In the description of this specification, the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or unit referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] like Figures 1-4 As shown, a magnetic climbing telescopic ladder includes multiple telescopic rods 1 that are telescopically interlocked and ladder steps 2 fixed on the telescopic rods 1. The multiple telescopic rods 1 are interlocked and assembled with each other. The ladder steps 2 are multiple and are fixed one-to-one on two telescopic rods 1 of the same height. The telescopic rods 1 and ladder steps 2 are made of aluminum alloy, which can reduce the overall weight while ensuring structural strength, making it convenient for handling and operation in this embodiment.

[0018] The step 2 is provided with a magnetic base 3 for magnetic fixation. The magnetic base 3 is fixedly connected to the step 2 via a connecting rod 34. In this embodiment, there are two magnetic bases 3 connected to the bottommost step 2.

[0019] The magnetic base 3 includes a magnetic block 31 for magnetic fixation. The magnetic base 3 is magnetically fixed to the hull by the magnetic block 31, so as to provide the main magnetic support force for fixation in this embodiment.

[0020] The telescopic rod 1 is rotatably fitted with magnetic feet 4. The magnetic feet 4 are arranged one-to-one on the telescopic rod 1, that is, there are two magnetic feet 4 installed on the telescopic rod 1 of the same height, which rotate relative to each other. In this embodiment, by setting up telescopic rods 1 that can be installed on each other, the telescopic rod 1, ladder 2 and magnetic feet 4 are modularly set up, which can be quickly telescopically assembled and is suitable for climbing on boats of different heights, which greatly improves the convenience of climbing and crawling in this embodiment.

[0021] One end of the magnetic foot 4 is equipped with a magnet 44 for magnetic fixation. Specifically, the magnetic foot 4 includes a hollow sleeve 41. The magnet 44 is disposed inside the sleeve 41 and can be driven to slide outward. When the magnet 44 slides outward, the magnetic foot 4 can be magnetically fixed to the hull by the magnet 44.

[0022] Furthermore, the magnetic base 3 provides the main magnetic support force for magnetic fixation to the hull, which is used in this embodiment. The magnetic feet 4 on the telescopic rod 1 provide multiple stable magnetic support points for climbing, thereby ensuring the stability and safety of climbing.

[0023] One side of the magnet 44 is positioned facing the port of the sleeve 41. A transmission pin 431 is fixed on the magnet 44 and passes through the sleeve 41. The transmission pin 431 is driven to move the magnet 44. That is, by driving the transmission pin 431 back and forth, the magnet 44 can be moved back and forth within the sleeve 41.

[0024] The sleeve 41 is provided with a groove 411 for the transmission pin 431 to move back and forth. The groove 411 extends back and forth. The transmission pin 431 passes through the groove 411 and extends outward. Furthermore, a wrench 42 is rotatably mounted on the sleeve 41. The wrench 42 is hinged to the transmission pin 431 via a slide plate 43.

[0025] By rotating the wrench 42, the magnet 44 inside the sleeve 41 is driven to slide outward and magnetically fix to the hull. When it is necessary to store it, the wrench 42 can be rotated in the opposite direction so that the magnet 44 slides back into the sleeve 41, which facilitates the disassembly of the magnetic feet 4. After the two magnetic feet 4 of the same height are rotated and stored, the magnet 44 between the two magnetic feet 4 can generate a small magnetic attraction force, so that the magnetic feet 4 can maintain a mutually magnetic storage state for subsequent storage and transportation.

[0026] A puller 32 is installed on the magnetic base 3, and a support leg 33 is installed on the puller 32. The support leg 33 is threaded onto the puller 32. By twisting the support leg 33 on the puller 32, one side of the magnetic block 31 on the magnetic base 3 can be driven away from the magnetic hull, so that the magnetic base 3 can be quickly and effortlessly removed. By twisting the support leg 33 in the opposite direction, the magnetic base 3 can be gradually magnetically fixed to the hull, thereby improving the efficiency of disassembly and installation of the magnetic base 3.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
