Technical Field

[0001] The utility model relates to the field of folding knives, in particular to a folding knife positioning structure based on an elastic locking piece. Background Art

[0002] As one of the most popular EDC (everyday carry) products, folding knives not only have the cutting function of the knives themselves, but consumers also pursue the convenience and playability of their use. Consumers are particularly keen on the structural design of blade unlocking. There is a folding knife locking structure based on an elastic locking plate, and its locking and unlocking are both achieved based on the elastic locking plate. However, this locking plate still has shortcomings. Specifically, it installs the elastic locking plate as a separate accessory between the two handle plates of the knife handle, which increases the thickness of the knife handle and reduces the grip feel. At the same time, the production of the elastic locking plate separately will also increase the use of raw materials, which is not conducive to the manufacturer's control of manufacturing costs. Secondly, the unlocking method of some existing folding knives is not safe enough, and there is a risk of cutting the user.

[0003] Therefore, it is necessary to study a new technical solution to solve the above problems. Utility Model Content

[0034] Refer to the attached Figures 1 to 10 In the embodiment of the utility model, a folding knife positioning structure based on an elastic locking piece includes a handle 10 and a blade 20, wherein the handle 10 has a storage compartment 11 for storing the blade 20, wherein the storage compartment 11 is provided with a pivot 12, and the blade 20 is rotatably mounted on the pivot 12; the handle 10 includes a first plate 13 and a second plate 14 connected to each other, wherein the storage compartment 11 is formed between the first plate 13 and the second plate 14, and the second plate 14 is integrally formed with an elastic locking piece 141;

[0035] The inner side (the left side in the drawings of this embodiment) of the elastic locking piece 141 has a first limiting portion and a second limiting portion, and the blade 20 has a first locking portion adapted to the first limiting portion and a second locking portion adapted to the second limiting portion;

[0036] The front end of the elastic locking piece 141 extends to the pivot 12 , and the pivot 12 is equipped with an unlocking device for pushing the elastic locking piece 141 to move to the other side (right side) of the first limiting portion.

[0037] In actual application, a screw hole is provided on the right end face (or the left end face) of the pivot 12, and the pivot 12 is mounted on the handle 10 by connecting screws, and the tightness of the blade 20 can be adjusted by adjusting the tightness of the connecting screws. Preferably, a travel rod 15 is also provided in the storage compartment 11, and the blade 20 is provided with a travel groove 21 corresponding to the travel rod 15, thereby further improving the stability of the product in use and avoiding accidents in the use of the knife. This is a prior art and will not be described in detail here.

[0038] Specifically, the first limiting portion is a limiting protrusion 1411 disposed inside the elastic locking piece 141, and the blade 20 is provided with a limiting groove 22 adapted to the limiting protrusion 1411. Preferably, the limiting protrusion 1411 and the elastic locking piece 141 are integrally formed.

[0039] The second limiting portion is a limiting steel ball 1412 installed on the inner side of the elastic locking piece 141, and the blade 20 is provided with a limiting hole 23 adapted to the limiting steel ball 1412. Preferably, it also includes a mounting block 1413, and the mounting block 1413 is provided with a mounting hole adapted to the limiting steel ball 1412. The limiting steel ball 1412 is installed on the elastic locking piece 141 through the mounting block 1413, and the mounting block 1413 is installed on the elastic locking piece 141 through a connecting screw. It should be supplemented that the mounting hole can be hemispherical, so that the limiting steel ball 1412 is installed from the right side of the mounting hole and will not slide out from the left side of the mounting hole.

The return spring 31 provides elastic force for the unlocking button 30 to return to its initial position (left side).

[0041] See also Figures 5 to 7 When in the unfolded state, the limiting groove 22 of the blade 20 and the limiting protrusion 1411 are positioned and locked, so that the blade 20 can no longer continue to rotate downward (counterclockwise). At the same time, due to the limiting effect of the stroke rod 15, the blade 20 can no longer continue to rotate upward (clockwise), that is, the rotation of the blade 20 in both directions is locked.

[0042] When unlocking is required, the unlocking button 30 is pressed, and the unlocking button 30 pushes the elastic locking piece 141 to move rightward (offset), so that the limiting protrusion 1411 is separated from the limiting groove 22, and the unlocking is completed; so that the blade 20 can be rotated downward and stored back in the storage compartment 11. Figures 8 to 10 As shown, in the storage locked state, the limiting steel ball 1412 is located in the limiting hole 23. Due to the action of the travel rod 15, the blade 20 cannot continue to rotate counterclockwise. At the same time, due to the action of the limiting steel ball 1412, it cannot rotate clockwise, that is, the locking is completed. When unlocking is required, the unlocking button 30 is pressed, and the unlocking button 30 pushes the elastic locking piece 141 to move to the right (offset), so that the limiting steel ball 1412 is separated from the limiting hole 23, and the unlocking is completed.

[0043] The design focus of the utility model is that the elastic locking piece is integrally formed on the knife handle, thereby omitting the production and installation of the elastic locking piece in the prior art, making assembly more convenient and improving production efficiency;

[0044] Secondly, unlocking the elastic locking piece by means of an unlocking device is safer than some folding knives which require the elastic locking piece to be swung by hand.

[0045] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
