Description
Technical Field
[0001] The utility model relates to the technical field of double-drum rivets, in particular to a waterproof double-drum rivet. Background Technique
[0002] At present, sealing strips are provided at the door leaves of dry cargo containers and box trucks to solve the sealing between each door and between the door leaf and the box body. The whole system requires a relatively large number of rubber strips. The sealing strips are generally installed last and fixed on the doors of dry cargo containers or box trucks by rivets.
[0003] During the use of double-drum rivets, moisture will penetrate into the sealing strip through the gaps or pores of the rivets, resulting in a reduced fit between the sealing strip and the door leaf, thus affecting the sealing performance of the entire container or truck, and causing water to enter the box body through the rivets during use, causing losses to the goods in the dry cargo container or box truck. Content of the Utility Model
[0004] The purpose of the utility model is to provide a waterproof double-drum rivet to solve the problem that during the use of double-drum rivets as mentioned in the above background technique, moisture will penetrate into the sealing strip through the gaps or pores of the rivets, resulting in a reduced fit between the sealing strip and the door leaf, thus affecting the sealing performance of the entire container or truck, and causing water to enter the box body through the rivets during use, causing losses to the goods in the dry cargo container or box truck. To achieve the above purpose, the utility model provides the following technical solution: a waterproof double-drum rivet, including a nail shell, a nail cap is fixedly connected to the top of the nail shell, a waterproof pad is sleeved on the side surface of the nail shell, the top of the waterproof pad is fixedly connected to the nail cap, a waterproof sleeve is sleeved on the side surface of the nail shell, barbs are fixedly connected to the side surface of the waterproof sleeve, and a groove is opened on the side surface of the nail shell. Through the cooperation between the waterproof pad, the waterproof sleeve and the nail cap, the waterproof pad is located between the nail cap and the material, first forming a layer of seal, enhancing the sealing performance between the rivet and the material, effectively preventing moisture from invading from below the rivet cap. On this basis, the waterproof sleeve further wraps the outside of the nail shell, providing a second waterproof barrier for the rivet, ensuring that moisture will not invade the gap between the nail shell and the material, greatly enhancing the waterproof performance of the double-drum rivet, and reducing the corrosion and damage of goods caused by moisture penetration.
[0005] Further preferably, a fixing block is fixedly connected to one side of the groove, and a fixing groove is formed on the other side of the groove. Through the cooperation among the groove, the fixing block and the fixing groove, the fixing block and the fixing groove are added to the groove between the bulges, so that when the double-drum rivet is compressed, it can fit more closely with the material, reducing the gap between the rivet and the material, thereby enhancing the fixing effect of the connection, enabling the double-drum-shaped structure to be more stable, and effectively preventing the rivet from loosening or falling off during the force application process.
[0006] Further preferably, an expansion body is arranged at the bottom of the nail shell, the groove is formed on the side surface of the expansion body, and a waterproof ring is fixedly connected to the side surface of the expansion body. Adding a waterproof ring at the bulge of the double-drum rivet can form a sealing barrier, which can effectively prevent moisture from penetrating into the connection part between the rivet and the material, ensuring that the connection part always remains dry.
[0007] Further preferably, a nail base is movably connected to the bottom of the nail shell, a nail core is fixedly connected to the top of the nail base, and the nail core penetrates through and is connected inside the nail shell. During the riveting process, by the nail base jacking up upwards, it helps the bulging part to be squeezed, so as to be compressed into a double-drum-shaped structure.
[0008] Further preferably, a nail rod is fixedly connected to the top of the nail core, and an engagement groove is formed on the side surface of the nail rod. The design of the engagement groove enables the rivet gun to accurately capture and fix the rivet, making the riveting process smoother and more efficient.
[0009] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0010] In the present utility model, through the cooperation among the waterproof pad, the waterproof sleeve and the nail cap, the waterproof pad is located between the nail cap and the material, first forming a seal, enhancing the sealing performance between the rivet and the material, and effectively preventing moisture from invading from below the nail cap.

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technical staff in the art without creative work belong to the scope of protection of the present utility model.
[0020] Please refer to Figures 1 - 5, the present utility model provides a technical solution: a waterproof double-drum rivet, which includes a nail shell 1. A nail cap 2 is fixedly connected to the top of the nail shell 1. A waterproof pad 3 is sleeved on the side surface of the nail shell 1. The top of the waterproof pad 3 is fixedly connected to the nail cap 2. A waterproof sleeve 4 is sleeved on the side surface of the nail shell 1. Barbs 5 are fixedly connected to the side surface of the waterproof sleeve 4. A groove 6 is opened on the side surface of the nail shell 1. When in use, the staff inserts the nail shell 1 into the internal reserved hole between the container and the seal, and makes the waterproof pad 3 be between the nail cap 2 and the seal, blocking moisture from entering through the gap. At the same time, the barbs 5 outside the nail shell 1 enter the reserved hole along the direction. Due to its elasticity, it expands reversely and hooks the inner wall of the reserved hole, making the nail shell 1 tightly fixed to the inner wall of the reserved hole. There is a waterproof sleeve 4 between the barbs 5 and the nail shell 1, further blocking moisture from seeping through the gap.
[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 and Figure 4 shown, a fixing block 7 is fixedly connected to one side of the groove 6, a fixing groove 8 is opened on the other side of the groove 6, an expansion main body 9 is arranged at the bottom of the nail shell 1, the groove 6 is opened on the side surface of the expansion main body 9, and a waterproof ring 10 is fixedly connected to the side surface of the expansion main body 9. The fixing block 7 in the groove 6 will be stuck into the fixing groove 8, further clamping the nail shell 1, so that the nail shell 1 will not shift when being extruded.
[0022] In this embodiment, as Figure 1 , Figure 3 and Figure 5 shown, a nail base 11 is movably connected to the bottom of the nail shell 1. A nail core 12 is fixedly connected to the top of the nail base 11. The nail core 12 is connected through the inside of the nail shell 1. A nail rod 13 is fixedly connected to the top of the nail core 12. A connecting groove 14 is opened on the side surface of the nail rod 13. At this time, the nail rod 13 and the nail core 12 penetrate in sequence along the order of the nail cap 2 and the nail shell 1, and the nail base 11 is at the bottom of the nail shell 1. Subsequently, the staff uses a rivet gun to clamp the connecting groove 14, thereby connecting the nail rod 13. Then, the nail rod 13 is pulled outwards, so that the nail rod 13 drives the nail core 12 to move into the nail shell 1, making the nail base 11 squeeze the nail shell 1. Under the action of the three grooves 6, the expansion main body 9 bends, thereby squeezing the nail shell 1 into a double-drum shape, and the waterproof ring 10 outside the expansion main body 9 bends together, blocking moisture from entering the container interior.
[0023] The usage method and advantages of the present utility model: For this waterproof double-drum rivet, when in use, the working process is as follows:
[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, during use, the staff inserts the nail shell 1 into the internally reserved hole between the container and the seal, and positions the waterproof pad 3 between the nail head 2 and the seal to prevent moisture from entering through the gap. At the same time, the barbs 5 outside the nail shell 1 enter the reserved hole along the direction. Due to its elasticity, it expands reversely and hooks onto the inner wall of the reserved hole, tightly fixing the nail shell 1 to the inner wall of the reserved hole. There is a waterproof sleeve 4 between the barb 5 and the nail shell 1 to further prevent moisture from seeping through the gap. At this time, the nail rod 13 and the nail core 12 penetrate successively along the order of the nail head 2 and the nail shell 1, and the nail base 11 is at the bottom of the nail shell 1. Subsequently, the staff uses a rivet gun to clamp the connection groove 14 to connect the nail rods 13, and then pulls the nail rod 13 outwards, causing the nail rod 13 to drive the nail core 12 to move into the nail shell 1, making the nail base 11 squeeze the nail shell 1. Under the action of the three grooves 6, the expansion body 9 bends, squeezing the nail shell 1 into a double-drum shape. The waterproof ring 10 outside the expansion body 9 bends together to prevent moisture from entering the container interior. At the same time, the fixing block 7 in the groove 6 will snap into the fixing groove 8 to further clamp the nail shell 1, preventing the nail shell 1 from shifting during extrusion.
