The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort indicate or imply the relative importance of the indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] The existing lobster lock button and locking rod are assembled using a separate connection method. When the button is pressed, the stress is mainly concentrated at the connection between the button and the locking rod, resulting in low overall strength. With the increase of pressing frequency, fatigue damage and breakage can easily occur at the connection between the button and the locking rod, thus affecting the normal use of the lobster lock locking mechanism, shortening the service life of the lobster lock, and causing high maintenance and replacement costs. In order to solve the above technical problems, this paper proposes the following technical solution:

[0030] Referring to Figures 1-8, an aluminum alloy lobster buckle with an integrated button comprises: a hook body 1, and a buckle ring 2 rotatably connected to the bottom of the hook body 1. The hook body 1 includes an integrally formed arc-shaped portion 11 and a mounting portion 12. An opening for locking external objects is formed between the arc-shaped portion 11 and the mounting portion 12, and a locking member 3 is provided at the opening. The locking member 3 includes a locking rod 31 that is vertically installed in the mounting portion 12 in a columnar shape. A button 32 is integrally formed on the side wall of the locking rod 31, and the button 32 is disposed facing outward from the opening. A slide rail 121 is formed in the mounting portion 12 for the locking rod 31 to slide up and down along its axis.

[0031] The button 32 and the locking rod 31 are designed as a single piece, which significantly enhances the connection strength between the two. The connection between the button 32 and the locking rod 31 is more stable. When the button is pressed, the external force is distributed more evenly on the button and the locking rod, avoiding local stress concentration, thereby effectively reducing the risk of breakage. This improves the durability of the entire locking component, reduces the frequency of maintenance and replacement due to wear and breakage, and extends the service life of the lobster buckle.

[0032] The bottom of the mounting part 12 is also fitted with a cylindrical tube 13. The slide 121 is provided with an elastic element 4 that pushes the locking rod 31 upward. The elastic element 4 is located between the locking rod 31 and the cylindrical tube 13. The elastic element 4 can be a helical spring. Therefore, when the button 32 is not pressed, the elastic element 4 pushes the locking rod 31 upward along the slide 121, causing the top of the locking rod 31 to abut against the top of the opening of the arc-shaped part 11, causing the opening to be in a closed state.

[0033] To prevent the locking rod 31 from slipping outward from the opening when the spring pushes it upward to lock, the opening height of the existing hook body 1 is designed to be less than the length of the locking rod 31. Furthermore, to facilitate the installation of the locking component 3, the locking rod 31 includes an upper locking rod 311, a lower locking rod 312, and a connecting rod 313 arranged sequentially from top to bottom, as well as a fixing bolt 314 for connecting the upper locking rod 311, the lower locking rod 312, and the connecting rod 313. The lower locking rod 312 and the connecting rod 313 are both provided with through grooves for the fixing bolt 314 to pass through. The upper locking rod 311 is provided with a groove for the fixing bolt 314 to pass through. The internal thread of the connection; the button 32 is formed and connected to the side wall of the connecting rod 313; specifically, during installation, the bottom of the upper locking rod 311 is aligned and overlapped with the top of the connecting rod 313, and is inserted downward from the top of the slide rail 121, while the lower locking rod 312 is inserted upward from the bottom of the slide rail 121 until the top of the lower locking rod 312 abuts against the bottom of the connecting rod 313, and then the fixing bolt 314 is inserted upward from the bottom of the lower locking rod 312, passing through the through grooves of the lower locking rod 312 and the connecting rod 313 in sequence, and then connected to the internal thread at the bottom of the upper locking rod 311, thereby completing the installation of the locking component.

[0034] Furthermore, in order to ensure the stability of the connection between the cylindrical tube 13 and the mounting part 12, and to facilitate the installation of the mounting part 12 and the cylindrical tube 13, the cylindrical tube 13 is rotatably connected to the bottom of the mounting part 12 around the axis of the mounting part 12. A first annular groove 122 is formed at one end of the mounting part 12 connected to the cylindrical tube 13. A second annular groove 131 corresponding to the first annular groove 122 is formed inside the cylindrical tube 13. A feeding hole 132 is provided on the surface of the cylindrical tube 13 and is connected through the second annular groove 131. The diameter of the feeding hole 132 is less than or equal to the height of the second annular groove 131. The first annular groove 122 of the mounting part 12 is formed with an insertion hole 123 corresponding to the feeding hole 132. An iron wire 5 is installed between the first annular groove 122 and the second annular groove 131 through the feeding hole 132.

[0035] During assembly, first insert the cylindrical tube 13 into the bottom of the mounting part 12, and rotate the cylindrical tube 13 so that the feeding hole 132 is aligned with the insertion hole 123. Then, pass one end of the wire 5 through the feeding hole 132 and insert it into the insertion hole 123 to fix one end of the wire. Next, rotate the cylindrical tube 13 or the mounting part 12 to make the cylindrical tube 13 and the mounting part 12 rotate relative to each other around the axis of the mounting part 12. Since one end of the wire 5 has been fixed with the insertion hole 123, the wire 5 is fed into the first annular groove 122 and the second annular groove 131 through the feeding hole 132 during the rotation, thereby completing the connection between the mounting part 12 and the cylindrical tube 13.

[0036] To prevent the wire from protruding and affecting the appearance, the length of the wire is equal to the circumference of the first annular groove 122.

[0037] Secondly, in order to facilitate the rotation of the cylindrical tube 13 around the axis of the mounting part 12 during installation, the side wall of the cylindrical tube 13 is also formed with a mounting hole 133 for inserting a rod-shaped object to drive the cylindrical tube 13 to rotate along the axis of the mounting part 12. When it is necessary to rotate the cylindrical tube 13, one end of the rod-shaped object is inserted into the mounting hole 133, and then the rod-shaped object is pushed to rotate around the axis of the mounting part 12, thereby driving the cylindrical tube 13 to rotate synchronously.

[0038] The mounting part 12 has a guide rail 124 formed on its side wall for the button 32 to slide up and down. The guide rail 124 is connected to the slide rail 121, and the top of the guide rail 124 is connected to the opening, which makes it easy to lock the button 32 in the guide rail 124 during installation and prevent the locking rod 31 from swinging during installation. At the same time, the button 32 is fixed in the guide rail 124 and moves up and down during use, which enhances the smoothness of the button 32 during use.

[0039] The bottom of the cylindrical tube 13 is also fitted with a rotating rod 6, and the buckle 2 is rotatably connected to the bottom of the rotating rod 6. The bottom of the rotating rod 6 is also provided with a fastening ring 7 to prevent the buckle 2 from falling off. Thus, the buckle 2 can rotate freely around the axis of the rotating rod 6 during use, so as to realize the connection between the buckle 2 and the external object at different angles.

[0040] The side of the button 32 away from the locking lever 31 has a hemispherical structure, which conforms to ergonomic principles, making the touch softer when pressed and improving the user experience.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
