Description

Combined structure of device capable of locking and releasing a rope

This creation is related to a device that grasps a rope, especially a combined structure of a device that can lock and release a rope.

It is used to catch a rope device for outdoor, indoor, truck, camping or sailing. One is a cam cleat that simply grabs a rope, and the other is a rope that allows the rope to hold the load Clutch for the release of the rope. The aforementioned Cam Cleat is to be fixed (can not be moved in real time) and the rope can only be operated in one direction to tighten the rope and cannot relax the rope decrementally; the aforementioned clutch The device (Clutch) also needs to be fixed (can not be moved in real time). The rope can only be operated in one direction to tighten the rope and cannot be loosened gradually. It is equipped with a handle, and the operating range of pulling the handle is about 180 degrees. It is less convenient to use.

Most conventional devices for lifting an item use a rope to pass through a fixed pulley or a combination of fixed pulleys to lift an item, and a structure for locking the rope is further installed to achieve an instant lock and release of a rope The effect, such as US Patent 6,685,171, is equipped with a pulley, using a rotatable pawl (rotable pawl) and an engaging surface, for lifting an object can instantly lock the rope, and use a An arm that extends an appropriate length outward from the pawl, when a user swings the rope biasedly to push the arm, the effect of locking the rope can be achieved immediately when an item is lowered, but when an object is lowered (Release a rope), the pawl will have Approaching the engagement surface, in other words, the process of releasing a rope will cause the rope to rub the pawl irregularities, and in other words, the patent is implemented on market products, if the weight of a suspended item is less than 2.25 when it is released Kg, the suspended item cannot be released.

Auxiliary tools used for locking a rope or binding a tightening rope, such as US Pat. Nos. 7,428,769 and 8,141,212, which form a V-shaped groove on the outer side of a shell, and the inner wall of the V-shaped groove has a plurality of parallel The diagonal ridges of the arrangement, when a rope under tension (tensile) penetrates into and out of the shell, the exposed rope can be inserted into the V-shaped groove and clipped to achieve the effect of restraining the rope. The structure can fast and easily bind a tight rope, but can't bind a rope with too much tension. Furthermore, sometimes the rope will slip out of the V-shaped groove after being fixed, for example, it will happen, A cargo on a truck is bound by a rope with the aid of the aforementioned tools. When the truck travels, the cargo is vibrated, which may cause the rope to loosen.

In addition to the lack of functions in the above-mentioned conventional products, these products are also not easy in the assembly process. The placement and fixation of each part will take considerable time and manpower.

The main purpose of this creation is to provide a combined structure of a device that can lock and release a rope, which can be easily, quickly and accurately combined to reduce costs.

The secondary purpose of this creation is to provide a combined structure of a device that can lock and release a rope, which can smoothly and safely lift and release a heavy object

Another purpose of this creation is to provide a combined structure of a device that can lock and release a rope, which has a better effect to maintain the locked rope state.

Another purpose of this creation is to provide a device that can lock and release a rope The combined structure can be used to tighten a rope.

The reason is that in order to achieve the aforementioned purpose, the present invention provides a combined structure of a device that can lock and release a rope, which at least includes a shell with an internal space, the shell is provided with a communication portion for a The rope enters and exits the casing, and the interior of the casing includes at least an abutting portion, a cam, a torsion spring, and a starting portion. This creation has the effect of instantly locking and releasing a rope; Designed with a pair of first sliding parts, a pair of first positioning parts, a pair of second sliding parts and a pair of second positioning parts, and a third sliding part and the The design of a fourth sliding part on both sides of the starting part, and the design that the torsion spring is housed in the cam, the original creation can be easily, quickly and accurately combined to reduce the cost.
