Technical Field

[0001] This utility model relates to the field of cutting tool technology, specifically to a novel straight blade. Background Technology

[0002] Fixed blade knives typically use a sheath to protect the blade and edge, thus preventing users from injuring themselves while carrying them.

[0003] In existing technology, the blade and sheath of a straight knife are separate, and the sheath must be removed and stored separately when in use, otherwise the sheath is easily lost. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and provide a new type of straight blade.

[0005] One embodiment of this utility model provides a novel straight blade, comprising:

[0006] The blade has a blade body, and a cutting edge is formed on the side of the blade body;

[0007] The scabbard is slidably engaged with the blade. The scabbard can slide relative to the blade to a position where the blade extends from one side of the scabbard and to a protective position where the blade is covered by the scabbard.

[0008] In some alternative embodiments, a cutting tip is formed on the cutting edge;

[0009] The blade is provided with a first sliding track and a second sliding track, both of which extend in a direction close to the blade, and the extension angles of the first sliding track and the second sliding track are different.

[0010] The scabbard is provided with two sliders, which are slidably engaged with the first sliding track and the second sliding track respectively, and are rotatably engaged with the first sliding track and the second sliding track respectively. When the scabbard moves from the use position to the protection position, the scabbard rotates toward the protruding direction of the blade tip so that the scabbard covers the blade tip.

[0011] In some alternative embodiments, the scabbard is provided with at least one positioning structure, which engages with the blade when the scabbard is moved to the use position and the protection position.

[0012] In some optional embodiments, the positioning structure includes a positioning plate with a positioning part. The blade is provided with at least one first guide groove, at least one first positioning groove, and at least one second positioning groove extending in a direction close to the blade. When the scabbard is moved to the use position, the positioning part engages with the first positioning groove. When the scabbard is moved to the protection position, the positioning part engages with the second positioning groove.

[0013] In some optional embodiments, at least one elastic element is connected between the scabbard and the blade, and the elastic element undergoes elastic deformation when the scabbard moves to the protective position;

[0014] The blade is also provided with a movable switch, which has at least one pusher. When the sheath is in the protective position, the movable switch moves toward the positioning plate and can drive the positioning plate to disengage from the second positioning groove through the pusher.

[0032] The technical solutions of the present invention will now be clearly and completely described with reference to the accompanying drawings of the embodiments thereof. Please refer to... Figure 1 One embodiment of this utility model provides a novel straight blade, comprising:

[0033] The blade 10 has a blade 20, and the side of the blade 20 has a cutting edge 30.

[0034] The scabbard 40 slides in conjunction with the blade 20. The scabbard 40 can slide relative to the blade 20 to a position where the blade 30 extends from one side of the scabbard 40, and to a protective position where the scabbard 40 covers the blade 30.

[0035] The sheath 40 can slide relative to the blade 20 to a position where the blade 30 extends from one side of the sheath 40, thus facilitating cutting.

[0036] The sheath 40 can slide relative to the blade 20 to a protective position where it covers the blade 30, thereby effectively protecting the blade 30 and preventing it from injuring the user.

[0037] This novel straight knife cleverly connects the blade 20 and the sheath 40 together. When in use, the sheath 40 can slide to become one with the blade 20. The sheath 40 is easy to open; it can be opened with one hand. After opening, the sheath 40 stays attached to the blade 20 and is not easily lost. This also increases playability and improves the user experience.

[0038] Please see Figures 2 to 6 In some optional embodiments, a blade tip 31 is formed on the blade 30; a first sliding rail 21 and a second sliding rail 22 are provided on the blade body 20, both extending in the direction close to the blade 30, and the extension angles of the first sliding rail 21 and the second sliding rail 22 are different, and the first sliding rail 21 and the second sliding rail 22 gradually separate in the direction close to the blade 30; two sliders 41 are provided on the sheath 40, and the two sliders 41 slide with the first sliding rail 21 and the second sliding rail 22 respectively. The sheath 40 is dynamically engaged with the first sliding rail 21 and the second sliding rail 22 respectively. When the sheath 40 moves from the use position to the protection position, the sheath 40 rotates towards the protruding direction of the blade tip 31 so that the sheath 40 covers the blade tip 31. When the sheath 40 slides, the design of the first sliding rail 21 and the second sliding rail 22 being non-parallel and forming a certain angle allows the sheath 40 to rotate while sliding, so that the sheath 40 can rotate a certain angle to cover the blade tip 31, thereby effectively improving safety and effectively protecting the blade tip 31.

[0039] It should be noted that when the scabbard 40 is in the protective position, because the scabbard 40 rotates at a certain angle toward the blade tip 31, the part of the blade 30 away from the blade tip 31 will be exposed from the scabbard 40. This part can be left unsharpened or treated in other appropriate ways to make the part of the blade 30 exposed from the scabbard 40 harmless.

[0040] In some optional embodiments, the scabbard 40 is provided with at least one positioning structure 42. When the scabbard 40 is moved to the use position and the protection position, the positioning structure 42 is positioned and engaged with the blade 20. The positioning structure 42 positions the scabbard 40 so that the scabbard 40 can be stably maintained in the use position and the protection position.

[0041] The specific structure of the positioning structure 42 can be designed according to actual needs. For example, in some optional embodiments, the positioning structure 42 includes a positioning piece 43, on which a positioning part 44 is provided. The blade 20 is provided with at least one first guide groove 23, at least one first positioning groove 24, and at least one second positioning groove 25 extending in the direction close to the cutting edge 30. When the sheath 40 moves to the use position, the positioning part 44 engages with the first positioning groove 24, thereby stabilizing the positioning piece 43 and keeping the sheath 40 in the use position. When the sheath 40 moves to the protective position, the positioning part 44 engages with the second positioning groove 25, thereby stabilizing the positioning piece 43 and keeping the sheath 40 in the protective position. The positioning part 44, the first positioning groove 24, and the second positioning groove 25 can be hemispherical to reduce friction.

[0042] Please see Figure 7 In some optional embodiments, at least one elastic element 45 connects the sheath 40 and the blade 20. When the sheath 40 moves to the protective position, the elastic element 45 undergoes elastic deformation. The blade 20 is also provided with a movable switch 26, which has at least one pushing part 261. When the sheath 40 is in the protective position, the user can press the movable switch 26, causing it to move towards the positioning plate 43. The movable switch 26, through the pushing part 261, drives the positioning plate 43 to move, thereby causing the positioning part 44 on the positioning plate 43 to disengage from the second positioning groove 25. After the positioning part 44 disengages from the second positioning groove 25, the elastic force of the elastic element 45 drives the sheath 40 towards the use position, thereby achieving quick opening of the sheath 40 and convenient operation. In this embodiment, the elastic element 45 includes two springs, which are respectively disposed within the first sliding rail 21 and the second sliding rail 22, improving the stability of the springs.

[0043] In some optional embodiments, a ball bearing 262 is movably disposed on the pushing part 261. The pushing part 261 drives the positioning part 44 to disengage from the second positioning groove 25 via the ball bearing 262. The ball bearing 262 compresses the positioning piece 43, causing the positioning piece 43 to elastically deform in a direction away from the blade 20, thereby causing the positioning part 44 to disengage from the second positioning groove 25. After the sheath 40 moves toward the use position, the elastic force of the positioning piece 43 drives it to return to its original shape, thereby causing the positioning part 44 to press tightly against the blade 20 until the sheath 40 moves to the use position, at which point the positioning part 44 is pressed down into the first positioning groove 24 by the elastic force of the positioning piece 43.

[0044] In some optional embodiments, the blade 20 is provided with at least one second guide groove 27 extending in the direction close to the cutting edge 30. The inner side of the second guide groove 27 is provided with a first limiting groove 271 and a second limiting groove 272. The pushing part 261 slides with the second guide groove 27. The pushing part 261 is provided with an elastic limiting buckle 263. When the active switch 26 moves toward the positioning piece 43, the elastic limiting buckle 263 disengages from the first limiting groove 271. When the active switch 26 moves to the point where the pushing part 261 drives the positioning part 44 to disengage from the second positioning groove 25, the elastic limiting buckle 263 engages with the second limiting groove 272. By restricting the active switch 26 through the first limiting groove 271 and the second limiting groove 272, the user can clearly judge the position of the active switch 26 and achieve accurate operation. The elastic limiting buckle 263 also makes a "clicking" sound when it pops into the first limiting groove 271 and the second limiting groove 272, which enhances the playability. The active switch 26 can be manually reset by the user to return to the position where the elastic limit buckle 263 and the first limit groove 271 are in a limiting engagement.

[0045] The specific structure of the sheath 40 can be designed according to actual needs. For example, in some optional embodiments, the sheath 40 includes two protective shells 46, which are respectively arranged on both sides of the blade 20. Each protective shell 46 is provided with at least one positioning structure 42, which is positioned and engaged with the blade 20. In this embodiment, the slider 41 is connected between the two protective shells 46, and the positioning piece 43 is locked onto the protective shell 46 by screws.

[0046] In addition, in this embodiment, the protective shell 46 is provided with two positioning structures 42, and the blade 20 is provided with two first guide grooves 23, two first positioning grooves 24, and two second positioning grooves 25 on both sides, thereby improving the stability of the sheath 40. Furthermore, two second guide grooves 27 are provided on both sides of the blade 20, and the movable switch 26 has two corresponding pushing parts 261 on both sides of the blade 20. Each ball bearing 262 is driven and engaged with a positioning piece 43 of a positioning structure 42.

[0047] In some optional embodiments, a locking switch 11 is also movably disposed on the blade body 10. When the sheath 40 slides to the protective position, the locking switch 11 can move along the movement path of the sheath 40 to restrict the sheath 40 from moving toward the use position. The locking switch 11 further locks the position of the sheath 40 to prevent the sheath 40 from becoming loose and affecting the use of the blade 30. The locking switch 11 adopts a sliding design, which is relatively simple to operate. When the sheath 40 needs to protect the blade 30, the locking switch 11 moves to a position that avoids the movement of the sheath 40.

[0048] In some alternative embodiments, the blade body 10 is provided with a handle 12, and a side clip 13 is provided on one side of the handle 12. The side clip 13 can be fastened in a suitable position, such as the side of a trouser pocket. In this embodiment, a locking switch 11 is also provided on the handle 12.

[0049] The blade 30 is detachably coupled to the blade body 20, which facilitates processing and assembly. In this embodiment, the blade 30 is fastened to the blade body 20 with screws. In addition, since the blade 30 is detachable from the blade body 20, the blade 30 and the blade body 20 can be made of different materials. The blade body 20 can be made of a lighter material to achieve weight reduction.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
