[0027] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] like Figure 1-Figure 5As shown, the present invention provides a lashing bowl protective member, which is used to block the lashing hole at the deck 100 above the lashing bowl 200. The lashing bowl protective member includes a main body 1 and a protective member 2, wherein the protective member 2 is arranged at one end of the main body 1, and the main body 1 is used to cooperate with the inner side wall of the lashing hole. Specifically, a part of the outer side wall of the main body 1 along its axial direction is used to cooperate with the inner side wall of the lashing hole. The protective member 2 is used to fit with the surface of the deck 100 away from the lashing bowl 200, that is, the protective member 2 is used to fit with the upper surface of the deck 100. A sealing snap ring 3 and a limiting snap ring are arranged on the main body 1, and both the sealing snap ring 3 and the limiting snap ring can undergo elastic deformation. The materials of the sealing snap ring 3 and the limiting snap ring can be rubber, silicone or plastic. The sealing snap ring 3 and the limiting snap ring both protrude from the outer side wall of the main body 1, and the sealing snap ring 3 and the limiting snap ring are arranged at intervals along the axial direction of the main body 1, and the limiting snap ring is located on the side of the sealing snap ring 3 away from the protective member 2. The sealing snap ring 3 can be pressed against the inner wall of the lashing hole, so as to seal the gap between the main body 1 and the inner wall of the lashing hole. The limiting snap ring is used to fit with the surface of the deck 100 facing the lashing bowl 200, that is, the limiting snap ring is used to fit with the lower surface of the deck 100. By arranging the sealing snap ring 3 and the limiting snap ring that can undergo elastic deformation on the main body 1, the sealing snap ring 3 is pressed against the inner wall of the lashing hole to seal the inside of the lashing bowl 200, and the limiting snap ring and the protective part 2 are respectively fitted with the two sides of the deck 100 to achieve fixation, thereby reducing the risk of the lashing bowl protective part escaping from the lashing hole on the deck 100 above the lashing bowl 200.

[0029] Furthermore, a plurality of sealing clips 3 are provided, and the plurality of sealing clips 3 are arranged at intervals along the axial direction of the main body 1, and the plurality of sealing clips 3 are arranged in parallel. The plurality of sealing clips 3 are used to press against the inner side wall of the binding hole, thereby forming multiple seals between the main body 1 and the inner side wall of the binding hole, further improving the protective effect of the binding bowl 200. The number of sealing clips 3 can be 2, 3 or 4. In this embodiment, the number of sealing clips 3 is 2, so as to take into account the sealing effect while reducing the difficulty of installation and removal.

[0030] For details, please refer to Figure 2-Figure 3 As shown, the outer diameter of the main body 1 is smaller than the diameter of the lashing hole to ensure that the main body 1 can pass through the lashing hole smoothly during installation. The outer diameter of the sealing clip 3 is larger than the diameter of the lashing hole. During installation, the sealing clip 3 undergoes elastic deformation and presses against the inner wall of the lashing hole to form a seal. The diameter of the limiting clip is larger than the diameter of the sealing clip 3. During installation, the limiting clip undergoes elastic deformation and uses the gap between the main body 1 and the inner wall of the lashing hole to return to its original shape after passing through the lashing hole, and fits with the lower surface of the deck 100, so that the protective part 2 and the limiting clip are respectively fitted with the upper and lower sides of the deck 100, so as to fix the lashing hole protective part and reduce the risk of slipping out.

[0031] Furthermore, the spacing between two adjacent sealing clips 3 is equal, and the height of the sealing clips 3 protruding from the main body 1 is greater than the spacing between two adjacent sealing clips 3. During the installation process, the first sealing clip 3 located at the end away from the protective part 2 among the multiple sealing clips 3 undergoes elastic deformation first, and then the remaining sealing clips 3 undergo elastic deformation in sequence. The height of the sealing clip 3 protruding from the main body 1 is set to be greater than the spacing between two adjacent sealing clips 3, which can ensure that the two adjacent sealing clips 3 can overlap together during the deformation process, so that the multiple sealing clips 3 further fill the gap between the main body 1 and the inner side wall of the binding hole, and further increase the pressing force with the inner side wall of the binding hole to improve the sealing effect.

[0032] Furthermore, along the direction from the protective part 2 to the limiting snap ring, the distance between the first sealing snap ring 3 and the protective part 2 is greater than the height of the sealing snap ring 3 protruding from the main part 1. That is, the minimum distance between the multiple sealing snap rings 3 and the protective part 2 is greater than the height of the sealing snap ring 3 protruding from the main part 1. During the installation process, as the number of sealing snap rings 3 that undergo elastic deformation increases, the pressure required for installation also increases, and the first sealing snap ring 3 along the direction from the protective part 2 to the limiting snap ring undergoes elastic deformation in the final stage, at which time the remaining sealing snap rings 3 have already pressed against the inner wall of the binding hole. Therefore, in order to avoid excessive increase in the pressure required for installation, the distance between the first sealing snap ring 3 and the protective part 2 is greater than the height of the sealing snap ring 3 protruding from the main part 1, providing sufficient space for its elastic deformation so as not to press on the protective part 2.

[0033] Furthermore, the limiting snap ring includes a first limiting snap ring 4 and a second limiting snap ring 5. The first limiting snap ring 4 and the second limiting snap ring 5 are arranged at intervals along the axial direction of the main body 1, and the first limiting snap ring 4 and the second limiting snap ring 5 are parallel. The first limiting snap ring 4 is located on the side of the second limiting snap ring 5 facing the protective part 2, that is, the interval between the first limiting snap ring 4 and the protective part 2 is smaller than the interval between the second limiting snap ring 5 and the protective part 2. Therefore, the lashing bowl protective part can be applied to decks 100 of different specifications, please refer to Figure 4-Figure 5 As shown. Common deck 100 thicknesses include 6mm and 8mm. Figure 4 As shown, the interval between the first limit clamp ring 4 and the protective part 2 is set to 6 mm to be suitable for a deck 100 with a thickness of 6 mm; Figure 5As shown, the interval between the second limit snap ring 5 and the protective part 2 is set to 8mm to be suitable for the deck 100 with a thickness of 8mm. When the thickness of the deck 100 is 6mm, the installation process of the lashing bowl protective part is: match the main body 1 with the lashing hole, and press the protective part 2 downward, the second limit snap ring 5 first undergoes elastic deformation, and as the pressing continues, the first limit snap ring 4 and multiple sealing snap rings 3 undergo elastic deformation in turn, and the protective part 2 continues to be pressed downward until the second limit snap ring 5 and the first limit snap ring 4 pass through the lashing hole one after another, the first limit snap ring 4 returns to its original state and fits with the lower surface of the deck 100, and the protective part 2 fits with the upper surface of the deck 100. Similarly, when the thickness of the deck 100 is 8 mm, the installation process of the lashing bowl protective part is: match the main body 1 with the lashing hole, and press the protective part 2 downward, the second limit clamp 5 first undergoes elastic deformation, and as the pressing continues, the first limit clamp 4 and multiple sealing clamps 3 undergo elastic deformation in turn, and continue to press the protective part 2 downward until the second limit clamp 5 passes through the lashing hole. The second limit clamp 5 returns to its original state and fits against the lower surface of the deck 100. At the same time, the protective part 2 fits against the upper surface of the deck 100. At this time, the first limit clamp 4 is still located in the lashing hole and is tightly pressed against the inner wall of the lashing hole, further improving the sealing effect.

[0034] Optionally, the distance between the first limit snap ring 4 and the sealing snap ring 3 is greater than the distance between the first limit snap ring 4 and the second limit snap ring 5. During the installation process, the first limit snap ring 4 and the second limit snap ring 5 undergo elastic deformation in the binding hole, and the diameters of the first limit snap ring 4 and the second limit snap ring 5 are greater than the diameters of the sealing snap ring 3. Therefore, the first limit snap ring 4 and the second limit snap ring 5 require more space during movement in the binding hole to alleviate the excessive pressing force between them and the inner side wall of the binding hole. However, the space between the first limit snap ring 4 and the second limit snap ring 5 is not enough to provide sufficient deformation space for the elastic deformation of the first limit snap ring 4 and the second limit snap ring 5. Therefore, the distance between the first limit snap ring 4 and the sealing snap ring 3 is set to be greater than the distance between the first limit snap ring 4 and the second limit snap ring 5, and a deformation space is reserved between the first limit snap ring 4 and the sealing ring, thereby alleviating the problem of installation effort during the pressing process.

[0035] Optionally, the ratio of the diameter of the protective portion 2 to the outer diameter of the main body 1 is 1.5-2.5, for example, the ratio of the diameter of the protective portion 2 to the outer diameter of the main body 1 can be 1.5, 1.6, 1.7, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, or 2.5. In this embodiment, the ratio of the diameter of the protective portion 2 to the outer diameter of the main body 1 is preferably 2, so as to save materials and facilitate the operator to perform disassembly operations.

[0036] The main body 1, protective part 2, sealing clamp 3 and limiting clamp in this embodiment are integrally formed and manufactured, and the material is preferably polyethylene, and auxiliary materials and additives are added during the manufacturing process according to the use requirements to improve the processing performance and durability. The specific process method is the existing technology in this field and is not repeated here. In addition to providing protection for the lashing bowl 200, the lashing bowl protective part made of PVC material also has good fireproof performance to avoid ignition during hot work during the subsequent construction of the roll-on / roll-off ship. At the same time, the main body 1 is set as a hollow structure, which saves material consumption on the one hand, and provides a certain deformation space for the elastic deformation of the sealing clamp 3 and the limiting clamp on the other hand.

[0037] Since there are usually tens of thousands of lashing bowls 200 on a ro-ro ship, in order to avoid the adverse consequences caused by the failure of the protection of the lashing bowl 200, when the lashing bowl protection member in this embodiment is used to protect the lashing bowl 200, the sealing performance verification is first performed. The specific verification method is: after the lashing bowl protection member is installed, a circle of plastic film is pasted at a certain interval on the outer periphery of the protection part 2 using waterproof tape, and water is injected into the area surrounded by the plastic film so that the water level is higher than the upper surface of the protection part 2. After standing for a period of time, the plastic film and waterproof tape are removed, the moisture on the deck 100 is wiped off, and the lashing bowl protection member is removed. If the lashing bowl 200 is still dry, it proves that the sealing performance verification has passed. If a poor seal occurs, the size of the sealing clip 3 is adjusted according to the situation and the verification is repeated until the sealing performance verification passes.

[0038] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
