Description

Technical Field

[0001] This utility model relates to the field of climbing equipment technology, specifically a rope ascender with a foot-mounted toothed structure. Background Technology

[0002] In outdoor climbing and high-altitude operations, ascenders are crucial equipment for moving upwards along ropes, and are essential for both safety and efficiency. Currently, common rope ascenders have many shortcomings.

[0003] From the perspective of the ratchet structure, the engagement between the ratchet and the rope in some ascenders is not firm enough. When bearing weight or subjected to vibration, the ratchet is prone to detaching from the rope, causing the ascender to slide down and posing a safety hazard. Moreover, the ratchet's reset often relies on simple springs or its own structure, resulting in unstable reset performance and difficulty in consistently ensuring effective engagement with the rope.

[0004] Regarding component connections, the connection between the waist rope hook and the ascender housing is often achieved using a single bolt or welding. Single bolt connections are prone to loosening due to concentrated stress, while welding is inconvenient for later maintenance and component replacement. When the waist rope hook is damaged, it is often necessary to repair or replace the entire ascender, increasing the cost of use and the difficulty of operation. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a rope-mounted foot-mounted toothed ascender.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: A rope foot-mounted toothed ascender of the present invention includes a shell, a left ratchet, a right ratchet, a waist rope hook, a shaft pin, and a torsion spring;

[0009] The left ratchet and the right ratchet are symmetrically arranged inside the housing, and the left ratchet and the right ratchet are hinged to the housing by the axle pin;

[0010] The torsion spring is sleeved on the shaft pin, and the two ends of the torsion spring abut against the left ratchet and the right ratchet, respectively;

[0011] The waist rope hook is installed at the top of the housing.

[0012] Preferably, the teeth of the left ratchet and the right ratchet have a barbed structure.

[0013] More preferably, the top of the outer shell is provided with a mounting hole, and one side of the waist rope hook is provided with a mounting screw. The mounting screw is adapted to the mounting hole, and a limiting nut is sleeved on the mounting screw.

[0014] Preferably, the top of the outer casing has at least two mounting holes, and one side of the waist rope hook has at least two mounting screws.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a rope-mounted foot-mounted toothed ascender, which has the following advantages:

[0017] The left and right ratchet teeth are symmetrically hinged within the outer casing, forming a stable engagement-reset structure in conjunction with the pivot pin and torsion spring. The torsion spring continuously provides a reset force to the ratchet teeth, ensuring a tight engagement with the rope and effectively preventing the ascender from slipping down the rope. This provides reliable support for climbers ascending the rope and significantly improves operational safety.

[0018] The left and right ratchet teeth are designed with barbed hooks, which can embed more firmly into the rope surface compared to ordinary teeth, increasing the biting force and further enhancing the fall protection effect. Especially when bearing the weight of the climber or encountering vibration, it can prevent the ratchet from detaching from the rope and improve the stability during the ascent.

[0019] The waist rope hook is assembled with the outer casing via a connection method using a mounting screw, mounting hole, and limit nut. This not only ensures a secure installation but also allows for flexible disassembly. When the waist rope hook wears or is damaged, there is no need to replace the entire ascender; simply unscrew the limit nut for replacement, reducing maintenance costs and operational complexity.

[0020] The top of the outer shell has at least two mounting holes, and the waist rope hook has at least two mounting screws. The multiple connection structures can distribute the force on the waist rope hook, avoid damage to a single connection point due to stress concentration, extend the service life of the components, and ensure the overall reliability of the connection between the waist rope hook and the outer shell, making it suitable for long-term high-intensity climbing operations.

[0025] 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.

[0026] Please see Figure 1-3 The present invention relates to a rope foot-mounted toothed ascender, comprising a housing 1, a left ratchet 2, a right ratchet 3, a waist rope hook 4, a shaft pin 5, and a torsion spring 6;

[0027] The left ratchet 2 and the right ratchet 3 are symmetrically arranged inside the outer casing 1, and the left ratchet 2 and the right ratchet 3 are hinged to the outer casing 1 by the axle pin 5;

[0028] The torsion spring 6 is sleeved on the shaft pin 5, and the two ends of the torsion spring 6 abut against the left ratchet 2 and the right ratchet 3 respectively;

[0029] The waist rope hook 4 is installed on the top of the outer casing 1.

[0030] The outer casing 1 of this technical solution provides a carrier for the installation and protection of components such as the left ratchet 2 and right ratchet 3. The left ratchet 2 and right ratchet 3 are hinged inside the outer casing 1 by a pivot pin 5 and can rotate around the pivot pin 5. A torsion spring 6 is sleeved on the pivot pin 5, with its two ends abutting against the left ratchet 2 and right ratchet 3 respectively, providing a restoring elastic force for the left and right ratchet 3. When the ascender is sleeved on the rope, the barbed teeth of the left ratchet 2 and right ratchet 3 will engage with the rope under the action of the torsion spring 6. When the feet drive the ascender to move upward along the rope, the engagement of the left and right ratchet 3 with the rope can prevent the ascender from slipping down, realizing the function of ascending along the rope; when it is necessary to adjust the position of the ascender to move downward, an external force can be applied to make the left and right ratchet 3 overcome the elastic force of the torsion spring 6 and rotate around the pivot pin 5, releasing the engagement with the rope, so as to be able to descend smoothly. The waist rope hook 4 is used to connect safety ropes and other components to ensure the safety of climbers.

[0031] The teeth of the left ratchet 2 and right ratchet 3 have a barbed structure. This structure can embed more firmly into the rope surface when in contact with the rope, increasing the biting force with the rope and further preventing the ascender from slipping when bearing the climber's weight, thus improving the stability and safety of the ascent process.

[0032] The outer casing 1 has a mounting hole 7 at its top, and a matching mounting screw 8 is provided on one side of the waist rope hook 4. A limiting nut is fitted onto the mounting screw 8. During installation, the mounting screw 8 is inserted into the mounting hole 7, and then the limiting nut is tightened to achieve a secure connection between the waist rope hook 4 and the outer casing 1. This connection method facilitates the installation and removal of the waist rope hook 4. When the waist rope hook 4 is damaged, it can be quickly replaced, and the installation state of the waist rope hook 4 can also be adjusted according to actual needs.

[0033] The top of the outer casing 1 has at least two mounting holes 7, and the side of the waist rope hook 4 has at least two mounting screws 8. The cooperation of multiple mounting holes 7 and mounting screws 8 can make the connection between the waist rope hook 4 and the outer casing 1 more stable, distribute the force on the connection part, avoid damage caused by excessive force on a single connection point, and improve the reliability of the overall structure.

[0034] Detailed Workflow

[0035] Assembly preparation: Prepare the following components: outer shell 1, left ratchet 2, right ratchet 3, waist rope hook 4, shaft nail 5, torsion spring 6, limit nut, etc.

[0036] Install ratchet and torsion spring 6: Place the left ratchet 2 and right ratchet 3 symmetrically inside the housing 1 and hinge them to the housing 1 by means of the shaft pin 5; put the torsion spring 6 on the shaft pin 5 so that the two ends of the torsion spring 6 abut against the left ratchet 2 and right ratchet 3 respectively, so as to provide them with a restoring elastic force.

[0037] Install the waist rope hook 4: Insert the mounting screw 8 on one side of the waist rope hook 4 into the corresponding mounting hole 7 at the top of the outer casing 1, then put on the limit nut and tighten it to complete the installation of the waist rope hook 4.

[0038] Rope setting: The assembled ascender is set onto the rope to be climbed. Under the action of the torsion spring 6, the barbed teeth of the left and right ratchet 3 engage with the rope.

[0039] Ascent Operation: Connect the ascender of this technical solution to the foot anchor. The climber's feet drive the ascender to move upward along the rope. The left and right ratchet teeth 3 firmly engage with the rope to prevent the ascender from slipping, thus achieving ascent along the rope.

[0040] Sliding adjustment: When it is necessary to adjust the position of the ascender downward, apply external force to make the left and right ratchet 3 overcome the elastic force of the torsion spring 6 and rotate around the shaft pin 5, loosening the engagement with the rope, pushing the ascender down the rope. After reaching the appropriate position, release the external force, and the left and right ratchet 3 will re-engage with the rope and be fixed under the action of the torsion spring 6.

[0041] Disassembly and maintenance: When the climb is over or maintenance is required, first remove the waist rope hook 4, then disassemble the axle pin 5 and other components, and inspect, clean or replace each component.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
