Technical Field
[0001] The utility model relates to a folding knife locking structure with an integrated tail ring lock buckle. Background Art
[0002] As an everyday tool, folding knives usually have a locking mechanism on the blade. The locking mechanism can prevent the blade from accidentally folding back and injuring the user's limbs during use, thereby ensuring the safety and reliability of the folding knife. At the same time, the folding knife should have a lightweight blade for easy daily carrying.
[0003] Many folding knives currently on the market have heavy blades designed to enhance the strength of the locking mechanism to ensure safety and reliability. However, heavy blades are not suitable for daily carry.

[0026] The following is a clear and complete description of the technical solution of the present invention, with reference to the accompanying drawings. It should be noted that, in the description of the present invention, terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0027] The present invention will be further described below with reference to the accompanying drawings.
[0028] like Figure 1-10 The figure shows a folding knife locking structure with an integrated tail ring lock, comprising a blade 1, a first handle 2, a second handle 3, and a blade locking assembly. The first handle 2 and the second handle 3 are connected, and the rear end of the blade 1 is rotatably connected between the first handle 2 and the second handle 3 via a spindle screw 4, allowing the blade 1 to be rotated between the first handle 2 and the second handle 3. The blade locking assembly is disposed between the first handle 2 and the second handle 3 to retain the blade 1 in place.
[0029] Specifically, the blade locking assembly includes a locking block 5, a connecting rod 6, and a tail ring lock buckle 7; the locking block 5 is connected to the tail ring lock buckle 7 through the connecting rod 6, the front end of the first handle 2 and the second handle 3 are connected by a first screw 8, and the rear end of the first handle 2 and the second handle 3 are connected by a second screw 9; the locking block 5 is rotatably connected to the first screw 8;
[0030] Specifically, a spring groove 10 is provided on the tail ring lock buckle 7, a spring 11 is provided in the spring groove 10, the second screw 9 is located at the upper end of the inner side of the spring groove 10, one end of the spring 11 is connected to the bottom surface of the spring groove 10, and the other end is connected to the second screw 9.
[0031] Specifically, an upper locking groove 12 and a lower locking groove 13 adapted to the locking block 5 are respectively provided on the upper and lower sides of the rear end of the blade 1 .
[0032] Specifically, the rear ends of the first tool handle 2 and the second tool handle 3 are connected to a blocking post 14 that limits the movement of the connecting rod 6 .
[0033] Specifically, in the initial state, the blade 1 is located between the first handle 2 and the second handle 3. At this time, the locking block 5 is clamped in the lower locking groove 13, so that the blade 1 cannot rotate. When it needs to be used, the tail ring lock buckle 7 is pulled upward, and the tail ring lock buckle 7 drives the locking block 5 to rotate through the connecting rod 6, so that the locking block 5 leaves the lower locking groove 13, and the blade 1 can rotate at this time. The blade 1 is rotated out, and the tail ring lock buckle 7 is released when the blade 1 is rotated. At this time, the spring 11 resets and pushes the spring groove 10, so that the tail ring lock buckle 7 returns to its original position. At this time, the blade 1 completes its rotation and the locking block 5 is clamped in the upper locking groove 12 of the blade 1, so that the blade 1 will not rotate and cut the hand during use;
[0034] Specifically, the same operation is performed when retrieving the blade 1. Pull the tail ring lock buckle 7 upwards. The tail ring lock buckle 7 drives the locking block 5 to rotate through the connecting rod 6, so that the locking block 5 leaves the upper locking groove 12. At this time, the blade 1 can be rotated. Rotate the blade 1 back between the first handle 2 and the second handle 3, and then release the tail ring lock buckle 7. The reset of the spring 11 will push the spring groove 10, so that the tail ring lock buckle 7 returns to its original position, so that the locking block 5 is locked in the lower locking groove 13, so that the blade 1 cannot rotate.
[0035] Specifically, during use, because the tail ring lock buckle 7 integrates the functions of blade locking, tail ring and lock buckle, when the blade is unfolded, the index finger is inserted into the tail ring and the palm of the hand tightens the handle. The grip force and the force of the spring form a combined force to press the locking block toward the blade locking groove, so the tighter the grip, the higher the locking strength.
[0036] Specifically, the front and rear ends of the first handle 2 and the second handle 3 are connected by a third screw 15. A gasket 16 is provided between the blade 1 and the first handle 2 and the second handle 3, and the gasket 16 is sleeved on the spindle screw 4.
[0037] Specifically, during use, the blade 1 is provided with an upper locking groove 12 and a lower locking groove 13, the front end of the tail ring lock buckle 7 is provided with a locking block 5, and the middle section of the tail ring lock buckle 7 is provided with a spring groove 10. The tail ring lock buckle 7 as a whole rotates clockwise around the axial hole of the locking block under the action of the spring 11, and the locking block is stuck in the locking groove of the blade to realize the expansion locking and closing locking of the blade.
[0038] Specifically, during use, the half ring provided at the rear end of the tail ring lock buckle 7 cooperates with the half ring at the rear end of the knife handle to form a tail ring. When the tail ring lock buckle 7 rotates counterclockwise around the locking block axis hole, the rear end of the tail ring lock buckle disengages from the rear end of the knife handle to form an opening, otherwise it closes into a tail ring, thus realizing the function of the lock buckle.
[0039] Specifically, during use, the tail ring lock buckle 7 not only integrates the functions of blade locking, tail ring and lock buckle, but the locking block 5 of the tail ring lock buckle also takes into account the limiting function of the blade, and there is no need to design a blade limiting column separately. Because of the above highly integrated design, a lightweight blade body is finally obtained.
[0040] This folding knife locking mechanism with an integrated tail ring lock is connected by a first handle 2 and a second handle 3. The rear end of the blade 1 is pivoted between the first and second handles 2 and 3 via a spindle screw 4, allowing the blade 1 to be rotated between the first and second handles 2 and 3. A blade locking assembly is positioned between the first and second handles 2 and 3 to retain the blade 1 in position. This provides a high-strength locking mechanism for safety and reliability, while maintaining a lightweight blade body for easy everyday carry.
[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
