Description

folding knife

technical field

The utility model relates to knives, in particular to a folding knife.

Background technique

Typical pocket knives include a handle and a knife attached to the handle. There is a groove on the handle of the knife. When the knife is turned inward, the blade can enter the groove, leaving only a small part of the back of the knife outside for the next time the knife is pulled out. The other is called a spring knife, where the knife retracts straight into the handle and compresses the spring. When ready to use, simply press the button on the handle and let the spring eject the knife out of the handle.

Whether it is a folding knife or a switchblade knife, the length of the handle of the knife must be longer than that of the knife, so that the knife, especially the tip of the knife, can be completely accommodated in the handle to avoid danger. In fact, the length of the knife handle only needs to be suitable for holding by the hand, too large or too small has its disadvantages. However, when the size of the knife is larger, the size of the handle of the knife is also increased, which not only increases the weight, but also affects the handling.

Detailed ways

In order to describe the structure, features and effects of the present utility model in detail, the following preferred embodiments are given below together with the accompanying drawings.

As shown in FIGS. 1 to 5 , the folding knife provided by a preferred embodiment of the present invention is mainly composed of a handle 10 , a scabbard 42 and a knife 62 .

The handle 10 is mainly composed of a first outer plate 12, a first inner plate 14, a top plate 16, a second inner plate 18 and a second outer plate 20 (as shown in FIG. 4 ). A space with an opening downward is formed between the first inner panel 14 , the top panel 16 and the second inner panel 18 . The bottom surface of the top plate 16 has a notch, a guide rod 22 is arranged in the notch, its front end is fixedly connected to the top plate 16, and its rear end is suspended. A spring 24 is sheathed on the guide rod 22 , and its length under normal conditions is greater than that of the guide rod 22 . The first inner panel 14 is a metal sheet and has a first fastening portion 26 and a second fastening portion 28 , both of which are located on the same straight line. The first fastening portion 26 is an elongated hole, and a slope 30 is disposed on a front side of the elongated hole. And the second fastening portion 28 is a convex portion. An elastic release part 32 is arranged on the front side of the second fastening part 28, which is a free end of the first inner plate 14. Under normal conditions, the release part 32 is slightly warped outwards, and can be pressed inward (such as Figure 4, Figure 5). The second inner plate 18 is provided with two parallel long grooves, a first guide groove 34 and a second guide groove 36 . The second inner panel 18 also has a notch 38 for exposing the elastic release portion 32 to the outside. The inner side of the second outer panel 20 has a groove 40 corresponding to the second guide groove 36 of the second inner panel 18 .

The scabbard 42 has a chamber 44 with an opening downward. The rear end of the opening of the chamber 44 has a retaining portion 46 , and the front end of the retaining portion 46 has an inclined surface 48 (as shown in FIG. 6 ). A guide hole 50 is provided on the upper front end of the scabbard 42 through which the guide rod 22 can pass. A first guide block 52, a second guide block 54 and a third guide block 56 are arranged on the outer surface of the scabbard 42, wherein the second guide block 54 and the third guide block 56 are on the same straight line, and The third guide block 56 is higher than the second guide block 54 . The first guide block 54 is accommodated in the first guide groove 34 on the second inner panel 18 , and the second and third guide blocks 54 , 56 are accommodated in the second guide groove 36 . As shown in FIG. 4 , the third guide block 56 also extends into the groove 40 of the second outer plate 20 , and a spring 58 is arranged in the groove 40 to abut against the third guide block 56 and the side of the groove 40 . edge, to push against the scabbard 42 inwardly. A buckle 60 is a rod with a hook at the front end, and is arranged on the front end of the scabbard 42 .

The scabbard 42 is movable between an unfolded position (as shown in FIG. 3 ) and a retracted position (as shown in FIG. 2 ). When the scabbard 42 is in the expanded position, the scabbard 42 protrudes from the rear end of the handle 10, and the first guide block 52 and the second guide block 54 are located at the outermost sides of the first guide groove 34 and the second guide groove 36 respectively. And the fastening member 60 is fastened with the first fastening portion 26 to fix the scabbard 42 at the unfolded position. When the user pushes the scabbard 42 inwardly, the buckle 60 will leave the first buckle portion 26 along the slope 30, and the guide rod 22 will enter the guide hole 50 of the scabbard 42, and compress the spring 24, and then reach the retractable position. fit position. At this moment, the scabbard 42 will enter the space in the handle 10 , and the fastening member 60 will be combined with the second fastening portion 28 to fix the scabbard 42 at the retracted position.

As shown in Figures 5 and 6, if the scabbard 42 needs to be moved from the retracted position to the unfolded position, it is only necessary to press the elastic release part 32 to move the second buckle part 28 so that the second buckle part 28 and the buckle When the connector 60 is separated, the spring 24 will push the scabbard 42 to the unfolded position.

The rear end of the knife 62 is pivotally connected to the first inner plate 14 of the handle 10 by a rivet, and can be turned over between a use position (as shown in FIG. 2 ) and a folded position (as shown in FIG. 3 ). When the knife 62 is turned over to the use position, the knife 62 protrudes from the front end of the handle 10 , and the elastic release portion 32 will abut against the rear end of the knife 62 to fix the knife 62 in the use position. At this time, the scabbard 42 can be moved to the retracted position, so as to shorten the total length of the whole knife.

When it is necessary to fold the knife 62, the user needs to press the elastic release part 32 first, as shown in Figure 5 and Figure 6, so that the elastic release part 32 is no longer against the rear end of the knife 62, so that the knife 62 can move inward Flip. While pressing the elastic release part 32, the scabbard 42 is automatically bounced from the retracted position to the deployed position. When continuing to turn over the knife 62, the knife 62 will enter the space of the handle 10 and the chamber 44 of the scabbard 42.

As shown in FIG. 7 , when the knife 62 is about to enter the sheath 42 , the tip of the knife 62 will first contact the stop portion 46 of the sheath 42 and push the sheath 42 outward so that the knife 62 can enter the chamber 44 . After the knife 62 enters the chamber 44, the spring 58 will push the scabbard 42 inwards, so that the stopper 46 moves to the bottom of the tip of the scabbard, as shown in FIG. If the knife 62 needs to be used, it is only necessary to apply force to turn the knife 62 outwards. As shown in FIG. 9 , the tip of the knife 62 will first act on the slope 48 of the blocking portion 46 to move the scabbard 42 outward so that the scabbard 62 can be detached from the scabbard 42 . Continue to flip to reach the unfolded position. When the knife 42 reaches the unfolded position, the elastic release member 32 will automatically spring up to abut against the rear end of the knife 62 to fix the knife 62 at the unfolded position.

Based on the above description, it can be seen that the present invention provides a retractable scabbard, which can be extended to accommodate the scabbard when the scabbard is folded. And when the knife is turned out for use, the scabbard can be retracted into the handle of the knife to shorten the total length of the whole knife.
