Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for high-altitude operations, specifically to a track-type fall arrestor. Background Technology

[0002] In the field of safety protection for high-altitude operations, rail-mounted fall arrestors are the core equipment for ensuring the safety of workers.

[0003] In the field of high-altitude work safety, rail-mounted fall arresters are core equipment for ensuring the safety of workers. Existing fall arresters generally suffer from the following problems: First, the lock body structure design is not ergonomic, requiring significant external force for installation and disassembly, making operation laborious and prone to hand fatigue; second, during the opening and closing process, the components often jam, and the smoothness of the left and right lock bodies separating and merging is poor, affecting work efficiency; third, the locking mechanism is simplistic, relying solely on a single locking structure, which poses a risk of locking failure in extreme situations; fourth, the precision of key components such as the button shaft and main locking rod is insufficient, leading to loosening or misalignment after long-term use, reducing safety redundancy; furthermore, existing products often rely on secondary components such as springs to achieve basic functions, failing to highlight the uniqueness of the core locking structure, resulting in unclear product features, and even being deemed lacking in practical significance during the approval process, making it difficult to demonstrate the product's core advantages in safety protection. Utility Model Content

[0004] In view of the problems existing in the current fall arrest locks, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a track-type anti-fall lock, which solves the problems of insufficient ergonomic design, jamming during installation and disassembly, simple locking mechanism, and low precision of component matching in existing anti-fall locks.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A track-type anti-fall lock includes a left lock body and a right lock body. The left lock body has a limiting bracket at its top, a positioning pin on one side of the limiting bracket, a positioning groove fixedly formed on one side of the left lock body, a positioning pin slidably disposed in the positioning groove, a fixing groove fixedly formed on one side of the left lock body, a compression spring fixedly disposed in the fixing groove, a pressure cover fixedly disposed on one side of the compression spring, a button shaft passing through the pressure cover, a main lock rod fixedly disposed on one side of the left lock body, an active locking block passing through one side of the main lock rod, a torsion spring fixedly disposed on one side of the active locking block, a right lock body fixedly disposed on one side of the torsion spring, a fixing screw threaded at the bottom of the right lock body, a fixing shaft fixedly disposed at the bottom of the fixing screw, and a first plastic track and a second plastic track respectively on one side of the left and right lock bodies.

[0008] Preferably, the main locking rod wall is fixedly provided with a slot, and the stepped slot of the main locking rod is designed to gradually expand from one end near the button shaft to the other end, and the diameter of the first end of the slot is 3mm smaller than the diameter of the last end.

[0009] Preferably, one end of the button shaft matches the slot.

[0010] Preferably, both the button shaft and the main locking rod are made of stainless steel and have undergone surface hardening treatment.

[0011] Furthermore, the fixed shaft is knurled and riveted to prevent loosening.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model, through the double-locking structure achieved by the limiting bracket, and the cooperative design of the stepped hole groove of the main locking rod and the button shaft, directly reflects the core features of the product. When the limiting bracket is reset, the button shaft cannot be pressed, and the lock body cannot be pulled open and disengaged from the main track. Only when the limiting bracket is in the unlocked state can the button shaft be pressed and the lock body pulled open, causing the lock body to disengage from the track. The double-locking mechanism further enhances security protection. Compared with the existing design that relies on springs, this core structure better highlights the product's uniqueness and enhances its practical application value.

[0014] 2. The design of the limit bracket and the button shaft in this utility model reduces the operating force during installation and disassembly, conforms to the hand force application habits, and reduces operator fatigue; the stepped gradually expanding hole groove of the main locking rod and the sliding fit with the button shaft, combined with the elastic reset effect of the compression spring, make the separation and merging process of the left lock body and the right lock body smooth without jamming, improving the smoothness of operation.
