[0024] See also Figures 1 to 3 A large-size chest ascender with a positioning belt connecting hole includes an ascender body, an ascender outer frame 1 is provided on the body, and the ascender outer frame includes a bottom plate and a first connecting arm and a second connecting arm integrally connected to the bottom plate and arranged opposite to each other, and a spacing is provided between the first connecting arm and the second connecting arm to form an open structure; a ratchet 2 is connected to the first connecting arm through a ratchet pin 3, and the side wall of the ratchet is close to the bottom plate in a closed state, and a handle 5 is connected to the side wall of the ratchet through a handle pin 6, and the handle 5 is pulled to drive the ratchet 2 to swing relative to the ascender outer frame 1.

[0025] In this embodiment, the riser outer frame is formed by pressing a metal sheet at one time, presenting an open letter C shape. A ratchet 2 is installed at one end of the C shape formed by the riser outer frame 1. The two ends of the ratchet 2 each have a through hole for connecting other components. The ratchet pin 3 passes through the through hole at one end of the ratchet 2 and is connected to the riser outer frame; the ratchet 2 can swing in the riser outer frame 1 with the ratchet pin 3 as the axis; the ratchet reset spring 4 is wound around the ratchet pin 3, and the ratchet reset spring 4 can restore the ratchet 2 to its initial state after swinging; the opening and closing handle 5 is connected to the other end of the ratchet 2. The handle pin 6 passes through the through hole at one end of the handle 5 and the through hole at the other end of the ratchet to connect the two. The handle 5 can swing relative to the ratchet 2 with the handle pin 5 as the axis. The handle reset spring 7 is wound around the handle pin 6, and the handle reset spring 7 can restore the handle 6 to its initial state after swinging.

[0026] In a preferred embodiment, a gap is provided at the connection between the side wall of the ratchet 2 and the second side wall and the bottom plate to form a rope channel. The ascender can accommodate a rope and move unidirectionally along the rope.

[0027] In a preferred embodiment, the ratchet side wall is provided with sewage discharge teeth 8. The sewage discharge teeth are regularly arranged on the ratchet side wall.

[0028] In a preferred embodiment, a ratchet reset spring 4 is installed on the ratchet pin to achieve automatic reset of the ratchet.

[0029] In a preferred embodiment, a handle reset spring 7 is installed on the handle pin to achieve automatic reset of the handle.

[0030] In a preferred embodiment, a first opening 9 in the width direction is opened on the upper portion of the outer frame of the riser for connecting a positioning belt.

[0031] In a preferred embodiment, a second opening 10 is formed at the lower portion of the outer frame of the ascender for connecting a load-bearing belt.

[0032] During use, the ascender moves unidirectionally along the rope, the distance from the upper part of the ratchet 2 to the ratchet pin 3 is shorter, and the distance from the lower part to the ratchet pin is longer, thereby forming a center-biased semi-wheel structure. When the ascender moves downward relative to the rope, the eccentric ratchet will swing upward due to the friction of the rope. The more the ascender moves downward, the more the eccentric ratchet will swing upward accordingly. Thanks to the center-biased semi-wheel structure, the lower part of the eccentric ratchet is longer than the upper part, and it will form a clamping state with the outer frame of the ascender to the rope. The eccentric ratchet 2 and the C-shaped structure at one end of the outer frame 1 of the ascender clamp the rope together, which can prevent the ascender from continuing to move downward relative to the rope. On the contrary, when the ascender moves upward relative to the rope, the eccentric ratchet will swing downward due to the friction of the rope. The state of the eccentric ratchet and the C-shaped structure at one end of the outer frame of the ascender clamping the rope together will be released, and the ascender can continue to move upward along the rope. The eccentric ratchet swings limitedly relative to the outer frame of the ascender with the ratchet pin as the axis to accommodate ropes of different sizes.

[0033] When the opening and closing handle and the eccentric ratchet are in the initial state of being fitted, since one end of the opening and closing handle will press against the inner side of the ascender outer frame, the eccentric ratchet can only swing to a limited extent. In this state, since the eccentric ratchet can only swing to a limited extent, under the joint action of the ascender outer frame, the rope cannot fall off from the C-shaped structure of the ascender outer frame. Pull the opening and closing handle downward, and the end of the opening and closing handle pressing against the inner side of the ascender outer frame will leave the ascender outer frame. After the opening and closing handle leaves the ascender outer frame, it is pulled to one side, which can drive the eccentric ratchet to swing greatly. After the eccentric ratchet swings greatly, a large open space is formed between it and the ascender outer frame, and the rope can be put into or taken out of the ascender through this space. Stop pulling the opening and closing handle, and under the action of the handle reset spring, the opening and closing handle will be reset to the initial state of the eccentric ratchet fitting. At the same time, the eccentric ratchet will be reset to the initial state of the ascender outer frame under the action of the ratchet reset spring, and the regularly arranged ratchet dirt teeth can destroy and scrape away dirt such as mud covering the outer surface of the rope 14 when the rope passes through the ascender.

[0034] The first opening can be used to insert a braided belt to connect with the chest safety belt 11 to position the ascender, and the second opening can be used to hang various buckles 12 to connect with the positioning belt 13 to bear the main force and weight.

[0035] The utility model has the following beneficial effects:

[0036] 1. The first opening (positioning belt connection hole) on the upper part of the ascender is larger and longer, which can be adapted to a wider safety belt positioning belt, so that the connection between the ascender and the safety belt is more stable and the positioning is more accurate, so that the ascender can be adapted to a variety of ropes with different diameters;

[0037] The second opening (load-bearing connection hole) at the bottom of the ascender is larger in size and can accommodate connecting buckles of more sizes and models. The load-bearing connection hole bends and extends along the shape of the ascender's outer frame, allowing for connection between the ascender and the connecting buckle at various angles.

[0038] 2. When the ascender moves downward relative to the rope, the eccentric ratchet and the outer frame of the ascender can tightly clamp the rope, so that the ascender stops moving;

[0039] When the ascender moves upward relative to the rope, the force between the eccentric ratchet and the outer frame body of the ascender that clamps the rope is released, and the ascender can move upward along the rope.

[0040] 3. When there is dirt attached to the outside of the rope, the ratchet dirt removal teeth on the eccentric ratchet can destroy and scrape off the attached dirt, keep the outside of the rope clean, and improve the clamping stability of the eccentric ratchet and the outer frame of the ascender on the rope.

[0041] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
