Description

Technical Field

[0001] This utility model relates to a folding knife locking plate, belonging to the field of knife technology. Background Technology

[0002] The frame lock on a folding knife is a common locking mechanism, known for its high strength and reliability. The locking plate of a frame lock is usually made of titanium alloy, which, while lightweight and corrosion-resistant, will gradually wear down after prolonged friction with the groove at the base of the blade. This leads to a shallower locking depth, reducing the knife's reliability and security. Therefore, after a period of use, there's no need to return the knife for repair or replace the entire knife; the user only needs to replace the worn locking plate to continue using it. However, traditional frame locks typically have the locking plate integrally molded with the handle or fixed with screws. Replacement requires disassembling the spindle, adjusting shims, or even returning the knife for repair, which is cumbersome and relies on specialized tools. When users replace the locking plate themselves, improper tolerance control, such as deviations in plate thickness or elasticity, can easily lead to a loose lock or difficulty in opening and closing. Especially in outdoor or tactical scenarios, sudden locking plate failures are difficult to repair quickly, affecting the knife's reliability.

[0003] Therefore, there is an urgent need to propose a folding knife locking plate to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to solve the problem of high maintenance costs and complex operations caused by the need to disassemble the main shaft, adjust shims, and even return the lock plates of traditional frame locks for repair when replacing them.

A positioning through hole is provided at the corresponding projection of the replacement locking piece and the protrusion. When the replacement locking piece is installed in the mounting slot, the protrusion is located in the positioning through hole.

[0008] Preferably, the periphery of the mounting slot is a dovetail groove, and the periphery of the replacement locking piece is a dovetail mounting part that mates with the dovetail groove, with the dovetail mounting part fitting snugly into the dovetail groove.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0026] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections, also known as non-detachable connections, include but are not limited to conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include but are not limited to conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0027] Specific implementation method one: Combining Figures 1-4 This embodiment describes a folding knife locking plate, which includes a locking plate body 1 and a replacement locking plate 2. The locking plate body 1 has a mounting groove 3, and the replacement locking plate 2 is mounted in the mounting groove 3, which enables quick installation and removal of the replacement locking plate 2. The contact part between the locking plate and the knife head is separated into two independent modules, namely the locking plate body 1 and the replacement locking plate 2, realizing "one pull, one insert, one replacement" disassembly. Replacement can be completed without tools, greatly reducing the maintenance threshold.

[0028] Specific Implementation Method Two: Combining Figures 1-4 This embodiment describes a folding knife locking plate based on the folding knife locking plate described in Specific Embodiment 1. In this embodiment, the rear side wall of the mounting groove 3 is provided as an elastic sheet 4. The elastic sheet 4 has a protrusion 41 on the side that is in contact with the replacement locking plate 2. The replacement locking plate 2 has a positioning through hole 21 at the corresponding projection of the protrusion 41. When the replacement locking plate 2 is installed in the mounting groove 3, the protrusion 41 is located in the positioning through hole 21.

[0029] A further technical solution: The rear sidewall of the mounting groove 3 is machined with two elastic grooves, and the sidewall of the mounting groove 3 between the two elastic grooves forms an elastic sheet 4.

[0030] A more preferred technical solution is that the elastic sheet 4 and the mounting groove 3 are integrally formed.

[0031] The protrusion 41 is a spherical arc-shaped protrusion. The purpose is to both cooperate with the positioning through hole 21 to achieve positioning and reduce the difficulty of disassembly. That is, during disassembly, only an external object needs to be used to press the protrusion 41. Due to the elastic properties of the elastic piece 4, it undergoes elastic deformation under the action of external force, which can simultaneously pull the replacement locking piece 2 out of the locking slot 3. After the replacement locking piece 2 is pulled out, the elastic piece 4 automatically returns to its original position due to its elasticity.

[0032] Specific implementation method three: Combining Figures 1-5 This embodiment describes a folding knife locking piece based on specific embodiment one. The locking groove 3 has dovetail grooves 31 around its perimeter, and the replacement locking piece 2 has dovetail locking parts 32 around its perimeter that cooperate with the dovetail grooves 31. The dovetail locking parts 32 are fitted into the dovetail grooves 31. The standardized interface design of the dovetail grooves 31 and the dovetail locking parts 32 ensures precise alignment when replacing the locking piece 2, maintains the consistency of the locking engagement depth between the replacement locking piece 2 and the locking groove 3, and reduces tolerance sensitivity.

[0033] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutation and combination. Therefore, this utility model will not describe the technical solutions after permutation and combination one by one, but it should be understood that the technical solutions after permutation and combination have been disclosed by this utility model.

[0034] 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, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
