Description

Technical Field

[0001] This utility model relates to the structure of a fall arrestor; in particular, it relates to a detachable handle device for a fall arrestor. Background Technology

[0002] Existing fall arresters involve fixing the outer casing to one location and attaching one end of the rope, which extends out of the casing, to a harness worn by the person. When a person wearing the harness falls from the air, pulling the rope causes a hub inside the fall arrester to rotate rapidly. The hub's braking mechanism engages with a deceleration device fixed within the casing, preventing the hub from continuing to rotate and releasing the rope. This prevents the person from falling further, achieving a fall arrest safety effect.

[0003] The aforementioned fall arresters typically have a handle integrated into the outer casing to facilitate user gripping and carrying. However, the handle is usually integrally formed into the casing. Therefore, to change to a different handle shape, or for some fall arresters that do not require a handle, the outer casing must be replaced to alter the handle's shape or to omit the handle altogether. This structure makes the handle placement inflexible, hindering manufacturers and users from easily replacing the casing or removing the handle. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a structure in which a handle is detachably mounted on the outer shell. By designing that the handle can be detached from the outer shell, manufacturers or users can easily replace the handle with different shapes on the outer shell or remove the handle from the outer shell, making it convenient for users to use.

[0005] To achieve the above objectives, this utility model provides a detachable handle device for a fall arrestor, comprising a housing and a handle. The housing has a rope outlet and includes two half-housing units; the two half-housing units are detachably connected, forming an installation space inside the two half-housing units, and the rope outlet communicates with the installation space; each half-housing unit has a handle seat on one side, the two handle seats of the two half-housing units are brought together, a fixing rod is formed on the side of each handle seat near the installation space, and a handle recess is formed on the other side of each handle seat away from the installation space; each fixing rod has a free end, the two free ends of the two fixing rods are joined together, and the two handle recesses are merged to form a handle through-hole. The handle includes a grip and a connecting rod, the grip is for hand gripping, the connecting rod is connected to the grip and has a connecting part, the connecting part passes through the handle through-hole and has a through hole, the two fixing rods are inserted into both sides of the through hole, and the two free ends are located inside the through hole.

[0006] When this utility model is used to assemble a fall arrestor, a fall arrestor body is placed within the mounting space of the outer shell, and the rope of the fall arrestor body extends outward from the rope outlet. The advantage of this utility model is that by disassembling the two half-shells of the outer shell, the handle can be removed from the outer shell, and then handles of different shapes can be installed between the two handle seats. Alternatively, after disassembling the two half-shells of the outer shell and removing the handle, the two half-shells can be directly joined together, so that the outer shell does not have a handle. This design, which allows the handle to be detached from the outer shell, facilitates use by manufacturers and users. Attached Figure Description

A handle recess 113 is formed on the other side of each handle seat 11 away from the mounting space S, and a positioning flange 114 is formed around the periphery of each handle recess 113. The two handle recesses 113 are merged to form a handle through-hole 115. The outer surface of the rear bottom of each of the half-shells 10A has a semi-slot 131, and each semi-slot 131 is adjacent to the edge of each peripheral wall 14. The two semi-slots 131 of the two half-shells 10A are merged to form a slot 13, specifically, the slot 13 is a rectangular groove.

[0052] The handle 20 includes a grip 22, a connecting rod 24, and a insertion rod 26. Please refer to [link / reference needed]. Figures 3B to 5A As shown, the handle 22 is an arc-shaped rod with multiple anti-slip strips 221 on the side facing the outer casing 10 for hand gripping. The connecting rod 24 is connected to the top of the handle 22 and has a connecting part 241. The connecting part 241 passes through the handle opening 115, and the portion of the connecting part 241 inserted into the handle opening 115 has a through hole 242. The portion of the connecting part 241 passing through the handle opening 115 forms a positioning groove 243 around it, and the two positioning flanges 114 are embedded in the two sides of the positioning groove 243 for fixation. The two fixing rods 111 are inserted into the two sides of the through hole 242, and the two free ends 112 of the two fixing rods 111 are located in the through hole 242.
