Technical Field

[0001] This utility model relates to an anti-wear D-ring device, and in particular to an anti-wear D-ring device, belonging to the technical field of anti-wear D-rings. Background Technology

[0002] D-rings, as the name suggests, are shaped like the letter "D". They are metal rings commonly used for connecting, securing, or suspending objects, featuring a distinctive "D"-shaped cross-section. D-rings are widely used in various fields, including but not limited to mechanical engineering, automotive manufacturing, aerospace, outdoor sports equipment (such as rock climbing and mountaineering gear), construction, and agricultural machinery. In these fields, D-rings are typically used to connect components, secure structures, suspend heavy objects, or serve as part of safety devices. D-rings are usually coated with a wear-resistant material to enhance their abrasion resistance.

[0003] Currently, the wear resistance of some D-rings usually relies solely on the wear-resistant material on the surface. However, the material coated on the surface of D-rings is often affected by the environment. Some coating materials may be sensitive to environmental conditions, such as high temperature, humidity, and corrosive environments, which may cause the coating performance to degrade or fail. Furthermore, D-rings used in harsh environments may require more frequent maintenance and replacement of their coatings, thereby increasing maintenance costs and difficulty.

[0004] Therefore, there is an urgent need to improve an anti-wear D-ring device to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide an anti-wear D-ring device. By setting an anti-wear structure, it changes the traditional method of coating the D-ring body with wear-resistant material to improve the wear resistance of the D-ring body. This makes the wear resistance of the D-ring body unaffected by the environment. The advantage of this structure is that it can make the D-ring body have good wear resistance and is not affected by the environment. In addition, since this structure does not need to be replaced frequently, its maintenance cost and difficulty will be greatly reduced.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1-6 As shown in this embodiment, an anti-wear D-ring device embodiment is provided.

[0026] A wear-resistant D-ring device includes a D-ring body 1, with a wear-resistant structure 2 on the D-ring body 1. The wear-resistant structure 2 includes a first protective shell 3 and a second protective shell 4 fitted onto the D-ring body 1. Multiple fixing blocks 5 are fixedly installed on the second protective shell 4, and a connecting block 6 is fixedly installed at one end of each fixing block 5. Multiple fixing frames 7 that cooperate with the connecting blocks 6 are fixedly installed on the first protective shell 3. Both the fixing frames 7 and the connecting blocks 6 have connecting holes 8. A groove is formed inside the connecting hole 8 on the connecting block 6. A first insert 9 is movably installed inside the connecting hole 8, and a latch 10 is fixedly installed at one end of the first insert 9. By setting up the wear-resistant structure 2, the traditional method of coating the D-ring body 1 with wear-resistant material to improve its wear resistance is changed, making the wear resistance of the D-ring body 1 unaffected by the environment. Firstly, the first protective shell 3 and the second protective shell 4 are respectively clamped to both ends of the D-ring body 1 and brought into contact. When the first protective shell 3 and the second protective shell 4 are attached, the connecting block 6 at one end of the fixing block 5 will be inserted into the interior of the fixing frame 7, so that the fixing frame 7 will also be attached to the fixing block 5. Then, the first insert rod 9 is sucked into the interior of the connecting hole 8, and the first insert rod 9 is rotated so that the latch 10 is engaged in the groove on the connecting block 6, thereby fixing the connecting block 6 inside the fixing frame 7 to prevent it from falling off. Thus, the splicing of the first protective shell 3 and the second protective shell 4 can be completed. Rotating the first insert rod 9 in the direction of the first insert rod 9 will disengage the latch 10 from the groove, and the first insert rod 9 can be pulled out from the connecting hole 8. Then the first protective shell 3 and the second protective shell 4 can be separated, which makes it convenient for personnel to disassemble and replace the first protective shell 3 and the second protective shell 4 when they are damaged. The advantage of this structure is that the D-ring body 1 is not affected by the environment while having good wear resistance. Moreover, since this structure does not need to be replaced frequently, its maintenance cost and difficulty will be greatly reduced.

[0027] like Figure 5 As shown, both the first protective shell 3 and the second protective shell 4 are equipped with limiting blocks 11 at their bottoms. The limiting blocks 11 have semi-circular holes 12 and rounded edges. With the setting of the limiting blocks 11, semi-circular holes 12 and rounded edges, it is important to ensure the stability of the hook inside the D-ring body 1 since the D-ring is usually lifted by a hook. The limiting blocks 11 installed at the bottoms of the first protective shell 3 and the second protective shell 4, and the semi-circular holes 12 on the limiting blocks 11, can insert the hook, so that the hook can only move within the range of the semi-circular holes 12, thereby greatly improving the stability of the hook. At the same time, the design of the rounded edges can reduce the wear between the hook and the limiting blocks 11.

[0028] like Figure 5As shown, the limiting block 11 has a threaded hole 13, and multiple first bolts 14 connected to the first protective shell 3 and the second protective shell 4 are installed on the limiting block 11. Through the setting of the threaded hole 13 and the first bolts 14, the limiting block 11 can be fixed to the bottom of the first protective shell 3 and the second protective shell 4 by the multiple first bolts 14 to prevent it from falling off. After the multiple first bolts 14 are removed from the inside of the threaded hole 13, the limiting block 11 can be disassembled, which makes it convenient for personnel to disassemble and replace the limiting block 11 when it is damaged.

[0029] like Figure 3 and Figure 5 As shown, one end of the first bolt 14 has multiple toothed grooves 15, and the other end of the first insert rod 9 is fixedly equipped with multiple protrusions 16. The toothed grooves 15 and protrusions 16 increase the friction at one end of the first bolt 14, making it less likely for the hand to slip when the person rotates the first bolt 14, thus facilitating the installation and removal of the first bolt 14. At the same time, the multiple protrusions 16 at the other end of the first insert rod 9 increase its bearing area, making it easier for the person to rotate the first insert rod 9, thus also facilitating the installation and removal of the first insert rod 9.

[0030] like Figure 4 As shown, a retaining plate 17 is fitted onto the D-ring body 1, and multiple second bolts 18 are installed on the retaining plate 17. Nuts 19 are provided on the second bolts 18. Through the arrangement of the retaining plate 17, the second bolts 18 and the nuts 19, the protrusion 16 can be fixed to other objects by the multiple second bolts 18, thereby limiting the D-ring body 1 and preventing the D-ring body 1 from being pulled up when it is pulled. At the same time, the nuts 19 can make the second bolts 18 more stably connected to the object.

[0031] like Figure 4 and Figure 6 As shown, multiple first fixing plates 20 and second fixing plates 21 are fixedly installed on the second protective shell 4 and the first protective shell 3, respectively. A fastening rod 22 connected to the second fixing plate 21 is installed on the first fixing plate 20. One end of the fastening rod 22 is threaded, and a fixing cap 23 is installed on the fastening rod 22. By setting the first fixing plate 20, the second fixing plate 21, the fixing cap 23, and the fixing cap 23, the fastening rod 22 is inserted into the first fixing plate 20 until the other end of the second fixing plate 21. Then, the fixing cap 23 is tightened to one end of the fastening rod 22 and fits against the second fixing plate 21. This allows the second fixing plate 21 and the first fixing plate 20 to fit tightly together under the traction of the fastening rod 22, thereby improving the stability of the fit between the first protective shell 3 and the second protective shell 4.

[0032] like Figure 2As shown, both the card plate 17 and the D-ring body 1 are provided with insertion holes 24. The card plate 17 is equipped with a second insertion rod 25 that connects to the D-ring body 1. By setting the insertion holes 24 and the second insertion rod 25, the second insertion rod 25 is inserted into the insertion holes 24 to connect the card plate 17 and the D-ring body 1, thereby limiting the D-ring body 1 so that the D-ring body 1 is always in an upward state when it is pulled, which can prevent the hook hanging on the D-ring body 1 from shaking.

[0033] In this embodiment, as Figures 1-6 As shown, the working process of the anti-wear D-ring device provided in this embodiment is as follows:

[0034] First, the first protective shell 3 and the second protective shell 4 are respectively clipped onto both ends of the D-ring body 1 and brought into contact. When the first protective shell 3 and the second protective shell 4 are in contact, the connecting block 6 at one end of the fixing block 5 will be inserted into the interior of the fixing frame 7, so that the fixing frame 7 will also be in contact with the fixing block 5. Then, the first insert rod 9 is sucked into the interior of the connecting hole 8, and the first insert rod 9 is rotated so that the latch 10 is engaged in the groove on the connecting block 6, thereby fixing the connecting block 6 inside the fixing frame 7 to prevent it from falling off. Thus, the splicing of the first protective shell 3 and the second protective shell 4 can be completed. Rotating the first insert rod 9 in one direction will cause the latch 10 to disengage from the groove, and the first insert rod 9 can be pulled out from the connecting hole 8. Then the first protective shell 3 and the second protective shell 4 can be separated, making it convenient for personnel to disassemble and replace the first protective shell 3 and the second protective shell 4 when they are damaged.
