[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figure 1 This utility model provides a quick-release, anti-slip, high-strength, lightweight rope ladder, comprising: The rope ladder head 1 is connected to the rigid climbing ladder via quick-release pin 2. It is inserted into the pre-set holes of the rope ladder head 1 and the rigid climbing ladder, enabling tool-free disassembly. The rope ladder step 3 is made of carbon fiber composite board. The two ends of the rope ladder step 3 are embedded with bushings 5. The bushings 5 ​​can enhance the local bearing capacity and solve the stress concentration caused by the brittleness of carbon fiber. Fiber rope 6, ultra-high molecular weight polyethylene fiber rope, is used to connect the rope ladder head 1 and the rope ladder steps 3.

[0021] The quick-release connection structure of the quick-release pin 2 enables the rapid assembly and disassembly of the rope ladder head 1 and the rigid climbing ladder. The rope ladder steps 3, made of carbon fiber composite material, combined with the internal bushing 5 design, significantly reduces the overall weight while greatly improving the structural strength and load-bearing capacity. The ultra-high molecular weight polyethylene fiber rope 6 gives the product excellent weather resistance and wear resistance.

[0022] Furthermore, the distance between two adjacent soft ladder steps 3 is 380mm.

[0023] In one embodiment of this utility model, a self-resetting hanging ring 8 is also included, which is connected to the tail of the fiber rope 6 via a heart-shaped ring 7.

[0024] In one embodiment of this utility model, a cap 4 is installed at the end of the soft ladder step 3 to protect the end of the soft ladder step 3 from damage and to increase its aesthetics.

[0025] In one embodiment of this utility model, the bushing 5 is a metal bushing, preferably stainless steel or aluminum alloy, and the bushing 5 is concentrically arranged with the opening of the rope ladder step 3.

[0026] In one embodiment of this utility model, the quick-release pin 2 is a spring pin or a plug-type structure.

[0027] A spring pin is a quick-locking pin that automatically locks using the force of an internal spring, including: A pin is typically a hollow metal cylinder or a solid rod.

[0028] A lock ball / lock pin has one or more small steel balls that can partially protrude from the side of the pin.

[0029] The spring, installed inside the pin, is always in a compressed state.

[0030] The button / pull ring, located at one end of the pin, is used to overcome the spring force and release the lock.

[0031] How to use Insertion: Simply align the end of the pin with the locking bead with the connecting hole on the ladder frame and insert it firmly. A "click" sound or a distinct feeling of it being firmly in place indicates that it is locked.

[0032] Pull out: Pull or press the button / ring at the end of the pin to retract the lock ball completely into the pin body, and then you can easily pull out the entire pin.

[0033] Pin-type locking is a simpler and more direct mechanical locking method, which usually requires manual locking and unlocking, including: The pin, a sturdy metal rod, is the main load-bearing component.

[0034] The connecting ring / chain and one end of the pin are fixed to the ladder frame by a metal ring or short chain to prevent loss.

[0035] The locking hole is a through hole at the other end of the pin.

[0036] A cotter pin / safety pin is a separate, wire pin shaped like an "R" or "9" that passes through a locking hole in the pin shank to prevent it from coming loose.

[0037] How to use Insertion and locking: Insert the pin (the end connected to the fixing chain) through the hole on one side of the ladder frame, through the hole on the other side of the ladder frame, insert the cotter pin into the hole exposed at the end of the pin, and forcefully pry open the two "legs" of the cotter pin so that it opens in a "V" shape to complete the locking.

[0038] Unlocking and pulling out: First, close the two legs of the cotter pin, then pull it out of the pin rod. At this point, the pin rod can be pulled out of the hole in the ladder frame.

[0039] In one embodiment of this utility model, the surface of the soft ladder step 3 is provided with an anti-slip layer to ensure climbing safety. The anti-slip layer is fixed to the surface of the soft ladder step 3 by bonding or molding process to increase friction and prevent slipping during climbing.

[0040] In one embodiment of this utility model, the fiber rope 6 adopts a twelve-strand braided structure, which ensures excellent mechanical properties and durability.

[0041] In one embodiment of this utility model, the rope ladder head 1 adopts an asymmetrical structure. Specifically, the length of either end of the rope ladder head 1 is flush with the end of the rope ladder step 3. When climbing, whether the left foot or the right foot steps onto the step first, there can be a natural transition at the connection between the rope ladder head 1 and the hard climbing ladder, eliminating the problem of foot jamming caused by differences in climbing movements.

[0042] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element 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.

[0043] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
