Description

Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to a lockless pocket knife structure with an embedded steel lock head and titanium alloy back bone. Background Technology

[0002] Folding knives are commonly used in daily life, bringing much convenience. Among the folding knife styles on the market, the non-locking pocket knife is a type. Its main structure relies on a back spring plate located at the handle to lock the blade. This back spring plate is a slightly curved, elastic metal piece that holds the blade in place. However, existing non-locking pocket knives use steel for the back rib, which generally lacks sufficient elasticity. Some non-locking pocket knives use elastic steel for the back rib to compensate for the lack of elasticity, but this often results in insufficient hardness, poor wear resistance, and unsatisfactory performance. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a stable and durable pocket knife structure with an embedded steel lock head and titanium alloy back bone.

[0004] This utility model is achieved through the following technical solution:

[0005] A lockless pocket knife structure with an embedded steel lock head and titanium alloy back bone includes a handle, a blade hinged to the front end of the handle, a back bone installed on the inner side of the handle, an abutment corner at the end of the blade, and a steel lock head installed at the front of the back bone for the abutment corner to abut against. The back bone is made of titanium alloy.

[0006] Furthermore, the steel lock head is embedded and installed in the spine.

[0007] Furthermore, the steel lock head is installed on the spine with screws.

[0008] Furthermore, the back bone is provided with a mounting groove for installing the steel lock head, and the steel lock head protrudes from the back bone on the side near the abutting corner.

[0009] Furthermore, the blade is hinged to the tool holder via a spindle, and the blade is equipped with a bearing for connection to the spindle.

[0010] Furthermore, a secondary liner is provided between the blade and the handle, and several oil reservoirs are provided at the contact point between the secondary liner and the blade.

[0011] Furthermore, the blade has an outer arc surface at its end, and the spine has an inner arc surface at its end that matches the outer arc surface.

[0012] Furthermore, the upper surface of the blade is flush with the upper surface of the spine.

[0013] Furthermore, the knife handle includes a first knife handle plate and a second knife handle plate, which are fixedly connected by rivets.

[0014] Furthermore, the blade is provided with an operating groove.

[0015] Compared to existing technologies, this utility model features a steel lock head installed at the front of the back bone for the corner to abut against. The back bone is made of titanium alloy, replacing the traditional steel back bone. This retains the excellent elasticity and corrosion resistance of titanium alloy, while the addition of the steel lock head compensates for the low hardness and poor wear resistance of titanium alloy. This combination results in a back bone component with good elasticity and high wear resistance, improving the problem of rapid wear caused by the back bone being lower in hardness than the blade in order to retain elasticity in the traditional sliding pocket knife structure. It is stable, durable, and has good performance. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 This invention discloses a lockless pocket knife structure with an embedded steel lock and titanium alloy back bone. It includes a handle, a blade 1 hinged to the front end of the handle, a back bone 2 mounted on the inner side of the handle, a retaining angle 3 at the end of the blade 1, and a steel lock 4 mounted on the front of the back bone 2 for the retaining angle 3 to abut against. The back bone 2 is made of titanium alloy. By using a titanium alloy back bone instead of a traditional steel back bone, the advantages of titanium alloy's excellent elasticity and corrosion resistance are retained. The addition of the steel lock 4 compensates for the low hardness and poor wear resistance of titanium alloy, thus creating a back bone component with good elasticity and high wear resistance. This improves upon the problem in traditional sliding pocket knife structures where the back bone's hardness is lower than the blade's to maintain elasticity, leading to rapid back bone wear. The result is stable, durable, and performs well in use.

[0023] In one specific implementation, the steel lock head 4 is embedded and installed in the back bone 2, and the steel lock head 4 is installed securely.

[0024] As another specific implementation, the steel lock head 4 is installed on the back bone 2 by screws 5, and the steel lock head 4 is easy to install and remove.

[0025] The back bone 2 is provided with an installation groove 6 for installing the steel lock head 4, which facilitates the positioning and installation of the steel lock head 4 and improves the stability of the installation of the steel lock head 4. The side of the steel lock head 4 that is close to the corner 3 is exposed on the back bone 2, so as to avoid the corner 3 from contacting the back bone 2 and causing wear to the back bone 2.

[0026] The blade 1 is hinged to the tool holder via the spindle 7. The blade 1 is equipped with a bearing 8 for connecting to the spindle 7. The friction between the spindle 7 and the blade 1 is changed to rolling friction, which greatly reduces the friction between the spindle 7 and the blade 1, extends the service life of the parts, and increases the smoothness of opening and closing.

[0027] A secondary liner 9 is provided between the blade 1 and the tool holder. Several oil reservoirs 10 are provided at the contact point between the secondary liner 9 and the blade 1. The oil reservoirs 10 added at the contact point between the secondary liner 9 and the blade 1 are used to store lubricating oil and absorb metal shavings generated during friction, effectively lubricate and protect parts, improve service life, and have good performance.

[0028] The blade 1 has an outer arc surface 11 at its end, and the back bone 2 has an inner arc surface 12 that matches the outer arc surface 11 at its end. This ensures that the blade 1 is tightly connected to the back bone 2 when it is opened, preventing sharp corners on the back of the blade after it is folded. This avoids scratching the human body or objects, improving the safety of the knife during use. The blade is highly safe, and the blade and the back of the knife fit together perfectly, improving the overall stability of the knife structure and providing a good user experience.

[0029] The upper surface of blade 1 is flush with the upper surface of the back bone 2, so that blade 1 fits tightly with the back bone 2 after opening, thus improving the stability of the tool.

[0030] The knife handle includes a first knife handle plate 13 and a second knife handle plate 14, which are fixedly connected by rivets 15 to facilitate the assembly of the back bone 2, the steel lock head 4 and the secondary liner 9.

[0031] The blade 1 is provided with an operating groove 16 to facilitate the opening and closing of the blade 1.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
