Description

Technical Field

[0001] The utility model relates to an impact-resistant folding anchor fin, belonging to the technical field of ship anchors. Background Art

[0002] Anchoring equipment refers to the general term for the equipment and machinery used by ships when raising and dropping anchor. It consists of anchor, anchor chain, anchor chain barrel, chain stopper, anchor windlass, anchor chain compartment, anchor chain pipe and chain abandoner. The anchor is the main component of anchoring equipment. Anchor is an iron ship stopping device connected to the ship with an anchor cable and dropped on the bottom of the water or on the shore to stop the ship steadily.

[0003] Publication No.: CN105905243A, discloses a foldable anchor. During the lowering process of the anchor, the sea surface is prone to deformation of the anchor wing shaft due to excessive anchor dropping force and collision with sea water, which causes the anchor wing to be unable to rotate smoothly, thus affecting the use. The reason is that the bottom of the anchor wing shaft lacks protection and directly hits the sea surface, shortening the service life of the anchor, increasing costs and bringing inconvenience to users. Utility Model Content

[0004] The purpose of the utility model is to provide an impact-resistant folding anchor wing to solve the above-mentioned problems.

[0005] The technical solution adopted by the utility model is: an impact-resistant folding anchor wing, comprising an anchor rod, a ball head is provided at the bottom of the anchor rod, and a hanging rope hole is provided at the top;

[0006] The ball head and the anchor rod are integrally formed;

[0007] A slide cylinder is slidably arranged at the middle and lower position of the anchor rod and above the ball head. The slide cylinder is a rotating body, and a central hole for the anchor rod to pass through is arranged at its axis. The slide cylinder is evenly distributed with grooves with non-through bottoms around it, and an anchor wing is rotatably installed in each of the grooves.

[0008] A blocking cross bar is also arranged above the slide cylinder and penetrates the anchor rod transversely.

[0009] Furthermore, the outer wall of the anchor rod is also provided with a guide boss extending along the axial direction, and the inner wall of the central hole of the slide cylinder is provided with a corresponding guide groove.

[0010] Furthermore, the diameter of the ball head is larger than the diameter of the anchor rod and the ball head is connected by a circular arc.

[0011] The lower end of the central hole of the slide cylinder is an outer convex arc surface that matches the circular arc.

[0012] Beneficial effects:

[0013] The anchor is provided with a slide tube. During the lowering process, the lower surface of the slide tube contacts the seawater and does not cause impact to the rotating shaft of the anchor fin. At the same time, the bottom contact area of ​​the slide tube is large and the impact resistance is strong. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] See also Figure 1 to Figure 2 , an impact-resistant folding anchor wing, comprising an anchor rod 1, a ball head 1a is provided at the bottom of the anchor rod 1, a lanyard hole 3 is provided at the top, and the ball head 1a and the anchor rod 1 are integrally formed by high-temperature forging;

[0026] A slide cylinder 5 is slidably arranged at the middle and lower position of the anchor rod 1 and above the ball head 1a. The slide cylinder 5 is a rotating body, and a central hole for the anchor rod 1 to pass through is arranged at its axis. The slide cylinder 5 is evenly distributed with grooves 5a with a bottom that are not through, and an anchor wing 4 is rotatably installed in each of the grooves 5a.

[0027] A blocking cross bar 2 is also provided above the slide cylinder 5 and penetrates the anchor rod 1 transversely.

[0028] During the anchor lowering process, the ball head 1a at the bottom of the anchor rod 1 contacts the sea surface first, and then the slide tube 5 contacts the sea surface. Under the impact of a strong impact force, the slide tube 5 slides upward and is blocked by the blocking cross bar 2. The anchor wing 4 is physically protected by the slide tube 5, and its rotating shaft does not participate in the impact. Since the lower surface of the slide tube 5 contacts the sea water, it will not cause impact on the rotating shaft of the anchor wing 4. At the same time, the bottom contact area of ​​the slide tube 5 is large and the impact resistance is strong.

[0029] For guiding, the outer wall of the anchor rod 1 is further provided with a guiding boss 1 b extending along the axial direction, and the inner wall of the central hole of the slide cylinder 5 is provided with a corresponding guiding groove.

[0030] The anchor is generally processed by casting, and its transition surface adopts arc transition. When gripping the ground, the slide tube 5 slides downward or backward, and the lower part of the slide tube 5 will contact the ball head 1a. In order to reduce the impact when gripping the ground, the diameter of the ball head 1a is larger than the diameter of the anchor rod 1 and the transition is made by an arc at the joint.

[0031] The lower end of the center hole of the slide cylinder 5 is an outer convex arc surface that matches the arc. Figure 3 .

[0032] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
