This application claims priority to Chinese Patent Application 202323550510X, filed on Dec. 25, 2023, which is incorporated herein by reference.
The present invention relates to the technical field of locking devices, in particular to a locking device for marine anti-collision ball traction rope.
Marine anti-collision balls are specially used in certain terminals and ports. Due to the good flexibility of materials, the marine anti-collision balls can be used as buffer protection devices for yachts. The marine anti-collision balls are not easy to deform, so the marine anti-collision balls can be widely used in related industries. Marine anti-collision balls are usually hung on rails of boats via ropes when in use. At present, when an anti-collision ball is hung, a rope is usually tied to a rail of a boat, or the rope is fixed with a clasp matched with the rail. However, when the length of the rope is adjusted, the two methods are very troublesome, cannot quickly complete adjustment of the length of the rope, and seriously affect the work efficiency of boatmen. Therefore, a locking device for a marine anti-collision ball traction rope, which can not only quickly fix an anti-collision ball traction rope on the rail of a boat, but also facilitate the adjustment of the length of the traction rope, is required to be developed to improve the work efficiency of the boatmen.
The purpose of the present invention is to overcome the aforementioned defects existing in the use of existing marine anti-collision ball traction ropes, and to provide a locking device for a marine anti-collision ball traction rope which can not only quickly fix an anti-collision ball traction rope on the rail of a boat, but also facilitate the adjustment of the length of the traction rope.
The purpose of the present invention is achieved by the following technical scheme: a locking device for a marine anti-collision ball traction rope comprises a lock body, a rope hole formed in the lock body and penetrating the lock body from top to bottom, a lock cavity arranged at one end of the lock body and provided with an opening, a lock head arranged in the lock cavity and capable of swinging left and right, and a rope guide hole formed in the top of the lock body and communicating with the lock cavity; a rope locking hole is transversely formed in the movable end of the lock head and transversely penetrating the movable end of the lock head; a locking cavity is formed between the lock head and the side cavity wall of the lock cavity.
Further, the lock head is in a V shape or an L shape, and teeth are arranged on the end surface of the movable end of the lock head.
Further, a toothed plate matched with the teeth of the lock head is arranged at the lower end of the side cavity wall of the lock cavity, and the teeth and the toothed plate together form a rope locking tooth claw.
As a preferred scheme of the present invention, the rope hole is arranged vertically, or the rope hole is arranged obliquely.
Compared with the prior art, the present invention has the following advantages and beneficial effects:
The present invention has a simple structure. By enabling the anti-collision ball traction rope to pass through the rope hole from bottom to top, enabling the rope passing through the rope hole to bypass the rail and then pass through the rope guide hole, and then enabling the traction rope to pass through the rope locking hole, the traction rope between the rope guide hole and rope locking hole forms a bending. The traction rope exerts a pulling force on the lock head under the gravity of the anti-collision ball, so that the lock head swings toward the side wall of the locking cavity, and realizes self-locking under the action of pulling force. The traction rope is firmly stuck on the rope locking tooth claw formed by the teeth of the lock head and the toothed plate on the side wall of the locking cavity. The anti-collision ball can be quickly fixed on the rail; by pulling the traction rope located outside the locking cavity, the lock head swings toward the opening of the locking cavity, and the traction rope can be pulled to adjust the length, so that the present invention can quickly complete the fixation of the traction rope and length adjustment, and effectively improve the work efficiency of the boatmen.
