Description

Technical Field

[0001] This utility model relates to the field of seahorse nail technology, specifically a waterproof seahorse nail. Background Technology

[0002] Seahorse rivets (also known as seahorse rivets, steel structure rivets, and lightweight blind rivets) are high-strength fasteners with a special structural design that combines shear, tensile, and seismic resistance. They are widely used in industrial fields where high connection strength is required.

[0003] In existing technologies, after the core-pulling riveting process is completed, the rivet head of such rivets only relies on the contact between the rivet itself and the workpiece surface. However, since the rivet is relatively hard, it is difficult for it to completely adhere to the workpiece surface. This can easily create gaps, allowing water to enter the rivet hole through the gap between the rivet head and the workpiece, and then enter the interior of the workpiece from the rivet hole. As a result, the waterproof performance is poor. Therefore, a waterproof rivet is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a waterproof seahorse nail to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof seahorse nail, comprising a rivet head, an anchor fixedly disposed at the lower end of the rivet head, a pull rod disposed at the middle of the inner side of the anchor and the rivet head, one end of the pull rod extending to the outside of the rivet head for easy connection with a pull-out device, and the other end passing through the rivet head and fixedly connected to the bottom of the anchor to ensure that the anchor can be stably deformed under force, and a sealing mechanism for improving sealing performance is disposed on the outside of the rivet head, the sealing mechanism comprising a contact surface, a mounting groove, and a sealing ring, the contact surface being fixedly disposed on the outer surface of the lower end of the rivet head, and an annular mounting groove being formed on one side of the contact surface on the surface of the rivet head, the sealing ring being engaged inside the mounting groove.

[0006] Preferably, an extension ring is provided on the outer side of the rivet head, and several through holes are opened on the surface of the extension ring. Through these through holes and the extension ring, the device also has the function of injecting glue. In cases with high requirements, after anchoring is completed, the worker can inject glue into the workpiece between the extension ring and the sealing ring through the through holes using a syringe. After the glue solidifies, the sealing performance can be further improved, and the waterproof effect can be further enhanced.

[0007] Preferably, the pull rod surface is threaded, which facilitates the connection between the pull rod and the pulling device, thereby making it easier to deform the anchor and break the pull rod. The threaded structure design not only enhances the reliability of the connection between the pull rod and the pulling device, but also improves the overall ease of operation, thereby significantly improving riveting efficiency and anchoring effect.

[0008] Preferably, the surface of the pull rod is provided with a vulnerable groove, which allows the pull rod to be disconnected from a preset position after being stretched to a threshold force.

[0009] Preferably, the outer surface of the upper end of the pull rod is provided with a chamfer, which allows the pull rod to be inserted into the machine being pulled.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. When the contact surface and the workpiece surface are in close contact after anchoring, the sealing ring will also be in close contact with the workpiece surface. Thus, a sealing ring is embedded in the rivet head. When the rivet is pulled and tightened to complete the anchoring work, the sealing ring will be tightly attached to the workpiece surface. This can significantly improve the water discharge effect of the device and prevent water from entering the workpiece through the contact point between the rivet head and the workpiece.

[0011] 2. This utility model enables the device to also have the function of injecting adhesive through the through hole and the extension ring. In applications with high requirements, after anchoring is completed, the operator can inject adhesive into the workpiece between the extension ring and the sealing ring through the through hole using a syringe. After the adhesive solidifies, the sealing performance can be further improved, and the waterproof effect can be further enhanced. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a waterproof seahorse nail, including a rivet head 1, which serves as the upper main body of the device, with an anchor 2 fixedly connected to its lower end. A pull rod 3 is provided on the inner center of the anchor 2 and the rivet head 1, playing a crucial role in connection and force bearing within the entire device. One end of the pull rod 3 extends to the outside of the rivet head 1, a design that facilitates connection with a pull-out device, allowing the operator to easily connect the pull rod 3 to an external power source for subsequent pull-out action. The other end of the pull rod 3 passes through the rivet head 1 and is fixedly connected to the bottom of the anchor 2. This connection method ensures that the anchor 2 can stably bear force and deform during the pull-out process, thereby achieving a reliable anchoring effect.

[0016] To improve the sealing performance of the device, a dedicated sealing mechanism is provided on the outside of the rivet head 1. This sealing mechanism includes a contact surface 4, a mounting groove 5, and a sealing ring 6. The contact surface 4 is fixedly provided on the outer surface of the lower end of the rivet head 1. When the device is anchored, the contact surface 4 will fit tightly against the surface of the workpiece, providing basic support for the seal. On the surface of the rivet head 1, an annular mounting groove 5 is formed on one side of the contact surface 4, and the sealing ring 6 is engaged inside the mounting groove 5. The sealing ring 6 is made of a material with good elasticity and sealing performance. When the contact surface 4 is in contact with the surface of the workpiece, the sealing ring 6 will be compressed and undergo elastic deformation, thus fitting tightly against the surface of the workpiece, effectively preventing moisture from entering the interior of the workpiece through the contact point between the rivet head 1 and the workpiece, significantly improving the waterproof effect of the device.

[0017] An extension ring 7 is also provided on the outer side of the rivet head 1, and several through holes 8 are formed on the surface of the extension ring 7. This unique design gives the device the function of injecting adhesive to meet the needs of applications with extremely high waterproof requirements. After anchoring, when further improvement of sealing is required, the operator can use a syringe to inject adhesive into the workpiece between the extension ring 7 and the sealing ring 6 through the through holes 8. The injected adhesive has good adhesion and sealing properties, and after solidification, it can fill the tiny gaps between the extension ring 7 and the sealing ring 6, forming an additional sealing barrier, further enhancing the waterproof performance of the device, and ensuring that the workpiece maintains a good waterproof condition even in harsh environments.

[0018] The pull rod 3 has threads 9 on its surface, a design that greatly facilitates the connection between the pull rod 3 and the pull-out device. This threaded connection not only enhances the reliability of the connection between the pull rod 3 and the pull-out device, preventing loosening or detachment during the pulling process, but also improves the overall ease of operation. Operators simply need to rotate and screw the pull rod 3 into the corresponding interface of the pull-out device to quickly complete the connection, thus significantly improving riveting efficiency. Simultaneously, the reliable connection ensures that the pulling force is stably transmitted to the anchor 2 during the pulling process, allowing the anchor 2 to deform according to design requirements and achieve a good anchoring effect.

[0019] The surface of the tie rod 3 is also provided with a vulnerable groove 10, the position and size of which are carefully designed. When the tensile force on the tie rod 3 reaches a preset threshold force, the tie rod 3 will break off from the preset position of the vulnerable groove 10. This design allows the tie rod 3 to be easily separated from the device after the anchoring work is completed, avoiding any impact on the use and appearance of the device from any remaining tie rod 3. At the same time, the setting of the vulnerable groove 10 also ensures the controllability of the tie rod 3 during the stress process, ensuring that the anchor 2 can deform under appropriate tensile force and achieve reliable anchoring.

[0020] The upper outer surface of the pull rod 3 is provided with a chamfer 11, the design of which has important ergonomic significance. When the pull rod 3 is inserted into the machine, the chamfer 11 can guide it, allowing the pull rod 3 to enter the machine interface more smoothly and accurately, reducing resistance during insertion, avoiding damage to the pull rod 3 or the machine interface due to improper insertion, and improving operational efficiency and safety.

[0021] Working Principle: The installation method of this device is basically the same as that of a traditional seahorse nail. First, align the anchor 2 with the rivet hole on the workpiece, and then insert the entire device into the hole, ensuring that the anchor 2 is completely inside the rivet hole. Next, connect the end of the pull rod 3 extending outside the rivet head 1 to the pulling device, start the pulling device, and pull the pull rod 3. Under the action of the pulling force, the anchor 2 gradually deforms, cooperates with the rivet head 1, and tightly clamps the workpiece, thereby completing the anchoring work.

[0022] During the anchoring process, when the contact surface 4 is in close contact with the workpiece surface, the sealing ring 6 is also simultaneously compressed and in close contact with the workpiece surface. Since the sealing ring 6 is embedded within the rivet head 1, when the rivet is pulled and tightened to complete the anchoring process, the sealing ring 6 will adhere tightly to the workpiece surface under pressure, forming an effective sealing barrier. This prevents moisture from entering the workpiece through the contact point between the rivet head 1 and the workpiece, significantly improving the waterproofing effect of the device.

[0023] For applications requiring extremely high waterproofing, after anchoring, workers can further enhance the device's sealing performance by utilizing the adhesive injection function of the extension ring 7 and through-hole 8. Specifically, a syringe is used to inject an appropriate amount of adhesive into the workpiece between the extension ring 7 and the sealing ring 6 through through-hole 8. After injection, the adhesive gradually fills the tiny gap between the extension ring 7 and the sealing ring 6, and upon solidification, forms a robust sealing layer. Working together with the sealing ring 6, this layer further improves the device's waterproofing performance, ensuring the workpiece maintains excellent waterproofing even in harsh environments.

[0024] In summary, this waterproof seahorse nail, through its unique structural design, achieves reliable anchoring and excellent waterproof performance. It also boasts advantages such as convenient operation and reliable connection, meeting the requirements for riveting and waterproofing in various occasions and possessing broad application prospects.
