Description

Forming method of fixing pin hole of insulated carbine hook

The present invention is related to the forming method of the fixing pin hole; in particular, it refers to a forming method of the fixing pin hole of the insulated carbene hook.

General carbene hooks have been widely used in various working environments, for example, high-altitude working environments, bulk cargo fixing and lifting, and safety buckles for vehicles. Generally, the carbene hook is formed by the combination of the C-shaped body and the brake lever to form an O-shaped closed ring structure. When in use, the opposite ends of the closed ring structure are usually tied with two straps, that is, the two straps can be used by The carbene hooks in a closed ring structure are connected to each other, and a safe connection structure is formed by the carbene hooks.

However, in use, the two straps originally attached to the opposite ends of the carbene hook may cause the two straps to slide relative to the carbene hook due to the rotation of the carbene hook itself, so that the two straps slide to the same side of the carbene hook, or even overlap each other. , Resulting in a decrease in the overall safety of the above-mentioned connection structure. In addition, when the above-mentioned situation occurs in the secondary strap, the secondary strap cannot be easily removed from the carbene hook, resulting in inconvenience in use.

In order to solve the above problems, the existing carbene hook has a fixing pin passing through the main body of the carbene hook, and the fixing pin is used to separate the O-shaped closed ring structure into two independent and closed connection areas; When the two opposite ends of the carbene hook are blocked, the two straps can always be kept at the opposite ends of the carbene hook due to the partition of the fixing pin, and the above-mentioned two straps will not slide relative to the carbene hook or even overlap each other.

Although the fixing pin can effectively solve the above-mentioned problems, when the insulating carbine hook is manufactured, the fixing pin hole will be covered by the insulating layer, which increases the difficulty of manufacturing the insulating carbine hook with the fixing pin. Therefore, the general method for forming the fixing pin hole of the insulated carbine hook is still in urgent need of a solution.

In view of this, the object of the present invention is to provide a method for forming a fixing pin hole of an insulated carbene hook by forming a recess on the insulating layer corresponding to the perforation of the fixing pin, so that the removal tool can identify and correspond to the recess, and then remove The insulating material formed inside the perforation achieves the purpose of simply manufacturing an insulating carbine hook body with a fixing pin hole.
