Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and in particular relates to an ascender with a handle and a rope coaxially connected. Background Art

[0002] The outer frame of the existing ascender and the inner frame of the handle are all plate-shaped products in the same plane, and the axis of the grip handle and the axis of the rope are offset by a certain distance. When the user pulls down or pushes up the ascender, this deviation causes a torsion offset between the ascender and the rope, which increases the friction and affects the smooth passage of the rope, and causes unnecessary wear on the rope and the ascender. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an ascender with a handle and a rope coaxial line. By arranging the axis of the grip handle and the rope on the same plane, when the user pulls down or pushes up the ascender with force, the ascender and the rope will not deflect, thereby improving the service life of the ascender.

[0004] To achieve the above purpose, the technical solution of the utility model is:

[0005] An ascender with a handle coaxial with a rope, comprising an ascender body, an ascender outer frame and an eccentric ratchet arranged on the ascender body, the ascender outer frame being provided with a rope accommodating chamber and opening toward one side; the first end of the eccentric ratchet being rotatably mounted on the ascender body through a ratchet pin, the second end of the eccentric ratchet being located in the opening side of the rope accommodating chamber and being able to swing relative to the rope accommodating chamber, the eccentric ratchet cooperating with the rope accommodating chamber to enable the ascender to move upward relative to the rope; the ascender body being provided with a gripping handle, the gripping handle and the axis of the rope being arranged in the same plane.

[0006] Preferably, a ratchet return spring is provided on the ratchet pin.

[0007] Preferably, a ratchet opening and closing handle is provided at the second end of the eccentric ratchet through a handle pin.

[0008] Preferably, a handle return spring is provided on the handle pin.

[0009] Preferably, the holding handle is provided with a handle inner frame, and the handle inner frame and the rope bearing are in the same plane.

[0010] Preferably, a ratchet drainage tooth is provided on the side of the second end of the eccentric ratchet facing the rope.

[0011] Preferably, the upper and lower ends of the ascender are respectively provided with load-bearing connection holes for connecting with ropes.

[0012] Preferably, the ascender is further provided with a rope guide block, which is arranged on one side of the opening of the rope accommodating cavity and is used to cooperate with the opening of the rope accommodating cavity.

[0013] The beneficial effects of the utility model are:

[0014] The holding handle of the strong ascender of the utility model is configured such that the axis of the holding handle and the axis of the rope are in the same plane due to the bending deformation of the inner frame of the handle. When the user pulls down or pushes up the ascender with force, the ascender and the rope will not deflect. When the ascender moves downward relative to the rope, the eccentric ratchet and the main body of the outer frame of the ascender can tightly clamp the rope, so that the ascender stops moving. When the ascender moves upward relative to the rope, the force clamping the rope between the eccentric ratchet and the main body of the outer frame of the ascender is released, and the ascender can move upward along the rope.

[0025] See also Figure 1-4, an ascender with a handle coaxial with a rope, comprising an ascender body, an ascender outer frame 1 and an eccentric ratchet 4 arranged on the ascender body, the ascender outer frame 1 being provided with a rope accommodating chamber and opening toward one side; the first end of the eccentric ratchet 4 being rotatably mounted on the ascender body through a ratchet pin 5, the second end of the eccentric ratchet 4 being located in the opening side of the rope accommodating chamber and being able to swing relative to the rope accommodating chamber, the eccentric ratchet 4 cooperating with the rope accommodating chamber to enable the ascender to move upward relative to the rope; a gripping handle 3 is provided on the ascender body, and the gripping handle 3 and the axis of the rope are arranged in the same plane. The ascender outer frame 1 described above is formed by pressing a metal plate at one time, and presents an open letter C shape in the longitudinal axis. The ascender outer frame 1 can accommodate a rope, so that the ascender can move unidirectionally along the rope. The lower extension of the ascender outer frame 1 and the handle inner frame 2 are in an integral ring shape, and one side of the ring of the handle inner frame 2 covers the gripping handle 3. An eccentric ratchet 4 is installed at one end of the C-shaped form of the ascender outer frame 1. The two ends of the eccentric ratchet 4 each have a through hole for connecting other components. The distance from the upper part of the eccentric ratchet 4 to the ratchet pin 5 is shorter, and the distance from the lower part to the ratchet pin 5 is longer, thereby forming a center-offset semi-wheel structure. When the ascender moves downward relative to the rope, the eccentric ratchet 4 will swing upward due to the friction of the rope. The more the ascender moves downward, the more the eccentric ratchet 4 will swing upward accordingly. Thanks to the center-biased semi-wheel structure, the lower part of the eccentric ratchet 4 is longer than the upper part, and it will clamp the rope with the ascender outer frame 1. The eccentric ratchet 4 and the C-shaped structure at one end of the ascender outer frame 1 will 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 4 will swing downward due to the friction of the rope. The state of the eccentric ratchet 4 and the C-shaped structure at one end of the ascender outer frame 1 clamping the rope together will be released, and the ascender can continue to move upward along the rope. The eccentric ratchet 4 swings relatively to the ascender outer frame 1 with the ratchet pin 5 as the axis to accommodate ropes of different sizes. When the ratchet opening and closing handle 7 and the eccentric ratchet 4 are in the initial state of being fitted, since one end of the ratchet opening and closing handle 7 will press against the inner side of the ascender outer frame 1, the eccentric ratchet 4 can only swing to a limited extent. In this state, since the eccentric ratchet 4 can only swing to a limited extent, under the joint action of the ascender outer frame 1, the rope cannot fall off from the C-shaped structure of the ascender outer frame 1. When the ratchet opening and closing handle 7 is pulled downward, the end of the opening and closing handle pressing against the inner side of the ascender outer frame 1 will leave the ascender outer frame 1.

[0026] In the utility model, the handle inner frame 2 of the ascender holding handle 3 is bent and deformed so that the axis of the holding handle 3 and the axis of the rope are in the same plane. When the user pulls down or pushes up the ascender with force, the ascender and the rope will not deflect; when the ascender moves downward relative to the rope, the eccentric ratchet 4 and the main body of the ascender outer frame 1 can tightly clamp the rope, so that the ascender stops moving; when the ascender moves upward relative to the rope, the force clamping the rope between the eccentric ratchet 4 and the main body of the ascender outer frame 1 is released, and the ascender can move upward along the rope.

[0027] In this embodiment, a ratchet reset spring 6 is provided on the ratchet pin 5. The ratchet reset spring 6 is used to automatically reset the eccentric ratchet 4 after it is opened. The ratchet pin 5 passes through the through hole at one end of the eccentric ratchet 4 and is connected to the riser outer frame 1. The eccentric ratchet 4 can swing in the riser outer frame 1 with the ratchet pin 5 as the axis. The ratchet reset spring 6 is wound around the ratchet pin 5. The ratchet reset spring 6 can restore the eccentric ratchet 4 to its initial state after swinging.

[0028] In this embodiment, the second end of the eccentric ratchet 4 is provided with an opening and closing handle through a handle pin 8. Preferably, a handle reset spring is provided on the handle pin 8. The handle reset spring is used to automatically reset the handle after it is opened. The opening and closing handle is connected to the other end of the eccentric ratchet 4, and the handle pin 8 passes through the through hole at one end of the opening and closing handle and the through hole at the other end of the eccentric ratchet 4 to connect the two; the opening and closing handle can swing relative to the eccentric ratchet 4 through the handle pin 8 as an axis, and a handle reset spring is wound around the handle pin 8, and the handle reset spring can restore the ratchet opening and closing handle 7 to the initial state after swinging. After the opening and closing handle leaves the outer frame 1 of the ascender, it is pulled to one side, which can drive the eccentric ratchet 4 to swing greatly. After the eccentric ratchet 4 swings greatly, a large open space is formed between it and the outer frame 1 of the ascender, and the rope can be put into or taken out of the ascender through this space. Stop pulling the ratchet opening and closing handle 7, and under the action of the opening and closing handle reset spring 9, the ratchet opening and closing handle 7 will be reset to the initial state of the eccentric ratchet 4 being attached. At the same time, the eccentric ratchet 4 is reset to the initial state of the riser outer frame 1 under the action of the ratchet reset spring 6 .

[0029] In this embodiment, the gripping handle 3 is provided with a handle inner frame 2, and the handle inner frame 2 and the rope bearing are in the same plane. The handle inner frame 2 is bent and deformed so that the axis of the gripping handle 3 and the axis of the rope are in the same plane.

[0030] In this embodiment, the second end of the eccentric ratchet 4 is provided with a ratchet discharge tooth 10 on the side facing the rope. The regularly arranged wheel discharge teeth can destroy and scrape away dirt such as dirt wrapped around the rope when the rope passes through the ascender. When dirt is attached to the outside of the rope, the ratchet discharge teeth 10 on the eccentric ratchet 4 can destroy and scrape away the attached dirt, keep the outside of the rope clean, and improve the clamping stability of the eccentric ratchet 4 and the ascender outer frame 1 on the rope.

[0031] In this embodiment, the upper and lower ends of the ascender are respectively provided with load-bearing connection holes for connecting with ropes. The upper load-bearing connection hole 11 and the lower load-bearing connection hole 12 can be hung with various connection buckles to bear the main force and weight.

[0032] In this embodiment, the ascender is further provided with a rope guide block 13, which is arranged on one side of the opening of the rope accommodating cavity and is used to cooperate with the opening of the rope accommodating cavity. The rope guide block 13 is installed on the upper end of the eccentric ratchet 4 on the upper part of the ascender outer frame 1, and the rope guide block 13 is fixed to the upper part of the ascender outer frame 1 by a fixing screw 14.
