Description

Technical Field

[0001] The present application relates to the technical field of sealing nails, and in particular to a sealing nail self-locking structure. Background Art

[0002] Sealant nails are small parts used for sealing and fixing purposes, usually made of rubber, plastic or metal. They are designed to fill gaps, prevent liquid or gas leakage, and provide additional fixation or support when needed. Rubber sealant nails usually have good elasticity and sealing properties, suitable for sealing irregular-shaped gaps, while metal sealant nails have higher strength and durability, suitable for occasions that require higher strength fixation.

[0003] Compared with the actual use process, one of the existing sealing nails currently uses glue to self-lock the nails, thereby preventing the sealing nails from being separated from the fixed position after long-term use. However, this fixing method will oxidize as the use time continues, thereby losing the self-locking function, causing the sealing nail to lose its fixing ability.

[0004] Therefore, in order to solve the above problems, the present application provides a sealing nail self-locking structure.

[0005] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0007] The present application provides a self-locking structure of a sealing glue nail, comprising a sealing nail, a thermoplastic limiting head at the bottom end of the sealing nail, an embedded groove is provided in the middle of the inner side of the sealing nail, a sealing cover is thermoplasticized on the outer top of the sealing nail, a sliding groove is provided on the inner top of the sealing nail, an embedded rod is slidably embedded in the inner side of the embedded groove, an extension rod is thermoplasticized on the bottom end of the embedded rod, a plurality of extension rod bottom limiting claws are thermoplasticized on the bottom end of the extension rod, a docking groove is provided through the top end of the sealing cover, a limiting frame slide groove is provided at the bottom end of the docking groove at the bottom end of the sealing cover, a top cover is thermoplasticized on the top end of the embedded rod, limiting frames are thermoplasticized on both ends of the outer side of the embedded rod, a limiting cover is thermoplasticized on the outer top end of the embedded rod, and rebound rods are thermoplasticized on the top ends of the two limiting frames.

[0008] Preferably, the bottom end of the limiting cover is in contact with the top surface of the sealing cover.

[0009] Preferably, the lower sliding groove is connected to the docking groove.

[0010] Preferably, the two inner ends of the docking groove correspond to the two outer ends of the limiting head.

[0011] Preferably, the height of the lower sliding groove is greater than the height of the two limiting frames.

[0012] Preferably, the width of the lower sliding groove is smaller than the diameter of the embedded groove.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. The sealing nail is limited by sliding an embedded rod carrying a limiting mechanism inside the sealing nail, and the diameter of the sealing nail is increased by the limiting mechanism, so that the friction between the outer side of the sealing nail and the inner surface of the fixing hole is increased. Compared with the existing technology, it has a more efficient self-locking function and can increase the service life of the sealing nail. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0020] Embodiment 1

[0021] Reference Figure 1-Figure 3A self-locking structure of a sealing nail comprises a sealing nail 1, a limiting head 2 is thermoplasticized at the bottom end of the sealing nail 1, an embedded groove 3 is provided in the middle of the inner side of the sealing nail 1, a sealing cover 4 is thermoplasticized at the top of the outer side of the sealing nail 1, a sliding groove 5 is provided at the top of the inner side of the sealing nail 1, the width of the sliding groove 5 is smaller than the diameter of the embedded groove 3, an embedded rod 8 is slidably embedded in the inner side of the embedded groove 3, an extension rod 6 is thermoplasticized at the bottom end of the embedded rod 8, and a plurality of limiting claws 7 at the bottom of the extension rod 6 are thermoplasticized. In order to limit the embedded rod 8 relative to the sealing nail 1, a docking groove 9 is provided through the top end of the sealing cover 4, and the inner ends of the docking groove 9 correspond to the outer ends of the limiting head 2, and the sliding groove 5 is provided on the inner side of the sealing nail 1. The groove 5 is connected with the docking groove 9. In order to facilitate the installation of the limit mechanism, a limit frame slide groove 10 is opened at the bottom of the sealing cover 4 at the bottom of the docking groove 9. A top cover 11 is thermoplasticized on the top of the embedded rod 8, and limit frames 12 are thermoplasticized on both ends of the outer side of the embedded rod 8. In order to make the sealing nail 1 have a self-locking function and increase its limit fixing ability, the height of the lower slide groove 5 is greater than the height of the two limit frames 12, and a limit cover 13 is thermoplasticized on the top of the outer side of the embedded rod 8. In order to prevent the top limit mechanism installed on the outer side of the embedded rod 8 from being unfolded when not in use, the bottom end of the limit cover 13 is in contact with the top surface of the sealing cover 4, and the tops of the two limit frames 12 are thermoplasticized with rebound rods 14.

[0022] Working principle: First, the operator drills a hole on the surface of the object where the sealing nail 1 is to be embedded, and then embeds the sealing nail 1 into the drilled hole until the sealing cover 4 thermoplasticized on the top of the outer side of the sealing nail 1 fits with the surface of the object. Then, the operator presses the top cover 11, and then the top cover 11 will drive the thermoplastic embedded rod 8 at one end thereof to move in the embedded groove 3 opened on the inner side of the sealing nail 1. Since the bottom surface of the limiting cover 13 fits with the top surface of the sealing cover 4, the sealing cover 4 thermoplastically connected to the embedded rod 8 when it slides will drag off the thermoplastic connection structure between the limiting cover 13 and it as the embedded rod 8 moves.

[0023] And as the embedded rod 8 continues to move, the limit frames 12 thermoplastically formed at both ends of its outer side will gradually detach from the docking groove 9 that passes through the top of the sealing cover 4. After the limit frame 12 is completely separated from the docking groove 9, the two elastic limit frames 12 that are collected to limit the docking groove 9 will be expanded inside the limit frame slide groove 10 opened at the bottom end of the sealing cover 4. At the same time, during this period, the limit frame 12 will also slide down inside the sliding groove 5 opened on the inner side of the sealing nail 1, and the limit claw 7 at the bottom of the extension rod 6 thermoplasticized at the bottom end of the extension rod connected to the embedded rod 8 will also detach from the embedded groove 3 and unfold after losing the limit of the embedded groove 3, so that the embedded rod 8 is limited relative to the bottom end of the sealing nail 1. In this way, the limiting capacity of the inner wall of the hole can be increased by increasing the width of the embedded rod 8, and the service life and fixing time of the sealing nail 1 can be increased.

[0024] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
