Description

Technical Field

[0001] The utility model relates to the technical field of rivets, in particular to a drum-shaped double-lock rivet. Background Art

[0002] Drum double lock rivets are a type of fastener used to connect two or more materials. They usually consist of a head with a protrusion and a hollow tail. During installation, the tail is passed through the hole in the material to be connected and then compressed using a special tool. In this way, the tail will expand and form a drum-shaped structure, while the head will lock on one side of the connected material, thereby achieving a stable connection. Drum double lock rivets are widely used in aviation, automobiles, construction and other fields, and are particularly suitable for connections that require high strength and corrosion resistance. They can provide uniform force distribution and can withstand large tensile and shear forces, thereby ensuring the firmness and reliability of the connection.

[0003] Existing rivets may become loose during use. The reason may be that after long-term use, dirt has been attached to the surface for a long time, which may cause corrosion to the rivets after a period of time, thereby shortening the service life of the rivets and reducing the practicality of the rivets. In order to further improve the service life of the rivets, a new double-lock rivet is needed. Utility Model Content

[0036] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0037] Reference Figure 1 and Figure 2The utility model provides an embodiment: a drum-shaped double-lock rivet, comprising a nail rod 1, a threaded groove 3 is provided in the middle of the outer wall of the nail rod 1, a cleaning plate 4 is threadedly connected to the middle of the nail rod 1, a cleaning scraper 5 is fixedly installed on the left side of the top wall of the cleaning plate 4, a cleaning scraper 2 6 is fixedly installed on the right side of the top wall of the nail rod 1, a threaded ring 14 is provided inside the cleaning plate 4, a nail cap 7 is fixedly connected to the top of the nail rod 1, a locking cap 8 is threadedly connected to the middle and lower ends of the nail rod 1, and grooves 9 are provided at the four corners of the top wall of the locking cap 8; a protective pad 12 is fixedly connected to the outer wall of the nail cap 7.

[0038] Specifically, by rotating the nail rod 1, the cleaning scraper 1 5 and the cleaning scraper 2 6 on the top wall of the cleaning plate 4 can clean the thread grooves 3 that are difficult to reach of the rotating nail rod 1, thereby removing the dirt in the thread grooves 3, thereby ensuring that it always maintains the best condition during use. This cleaning method not only improves work efficiency, but also reduces various problems caused by dirt, greatly improves work efficiency, reduces the possibility of dirt affecting the installation or use of rivets, and thus extends the service life of the rivets.

[0039] Reference Figure 1 and Figure 3 A lubrication mechanism 2 is provided on the top wall of the nail cap 7, and the lubrication mechanism 2 includes a cover plate 201. The bottom wall of the cover plate 201 is provided on the top wall of the nail cap 7. The cover plate 201 is rotatably connected to the top wall of the nail cap 7 through a hinge 202. An entry groove 203 is provided in the middle of the inner wall of the nail cap 7. Oblique grooves 204 are provided on the left and right sides of the inner wall of the cover plate 201. Vertical grooves 205 are provided on the left and right sides of the inner wall of the nail rod 1; through grooves 15 are provided on the front and back sides of the inner wall of the cleaning plate 4.

[0040] Specifically, the inlet groove 203 is connected to the inclined groove 204, so that the protective oil can flow along the inclined groove 204. This design is conducive to achieving uniform distribution of the protective oil. The inclined groove 204 is connected to the vertical groove 205, which further guides the protective oil to flow to the outer wall of the nail rod 1. The role of the vertical groove 205 is crucial. It can ensure that the protective oil is evenly applied along the outer wall of the nail rod 1, thereby achieving the purpose of increasing the rivet protection effect. This design not only improves the application efficiency of the protective oil, but also ensures the coverage of the protective oil. The two through grooves 15 allow the protective oil to pass through the connection between the cleaning plate 4 and the nail rod 1 faster.

[0041] Reference Figure 1 , Figure 2 and Figure 3 The inner size of the threaded ring 14 matches the outer size of the middle part of the nail rod 1; a plurality of rubber rings 10 are fixedly connected to the bottom end of the nail rod 1 at equal intervals; rubber pads 11 are fixedly connected to the left and right sides of the bottom wall of the cleaning plate 4; an auxiliary hole 13 is opened on the top wall of the nail cap 7.

[0042] Specifically, the inner size of the threaded ring 14 matches the outer size of the middle part of the nail rod 1, so that the installation is smoother. The lock cap 8 can be restricted when not in use by multiple rubber rings 10 to avoid loss. Since the rubber ring 10 is made of rubber, the lock cap 8 can be inserted into the bottom end of the nail rod 1 through multiple rubber rings 10, thereby achieving the purpose of two-way locking. The auxiliary hole 13 makes it easy to install the rivet using tools.

[0043] Working principle: When it is used at the beginning, since the rubber ring 10 is made of rubber, the locking cap 8 can be rotated out of the bottom end of the nail rod 1 through multiple rubber rings 10, so that the locking cap 8 is separated from the bottom end of the nail rod 1. At this time, the cleaning plate 4 is located in the middle and lower part of the nail rod 1, and the bottom end of the nail rod 1 is aligned with the hole to be fixed. The cleaning plate 4 is manually stabilized, and the nail rod 1 is rotated so that the cleaning scraper 1 5 and the cleaning scraper 2 6 on the top wall of the cleaning plate 4 can clean the thread groove 3 opened in the middle part of the rotating nail rod 1, thereby reducing the possibility of dirt affecting the installation or use of the rivet, thereby extending the service life of the rivet and improving the fixing effect. By sleeve-mounting the locking cap 8 into the bottom end of the nail rod 1, the locking cap 8 moves vertically along the thread groove 3, thereby achieving the purpose of two-way locking, and by opening the cover plate 201, protective oil can be poured into the inlet groove 203, so that the protective oil flows through the inlet groove 203 and the inclined groove 204, and flows to the outer wall of the nail rod 1 through the vertical groove 205, thereby increasing the protection effect of the rivet.

[0044] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
