Description

Folding knife that can be quickly disassembled and assembled

The present invention relates to a folding knife, and particularly refers to a folding knife provided with an inlay, so that the user only needs to operate the inlay to quickly disassemble and assemble the folding knife.

According to the fact that the folding knives currently sold in the market are composed of a handle and a knife body, the knife body and the knife handle are pivotally connected to each other, so that the knife body can rotate along its pivot position and be rotated to the Outside of the knife handle, it may be rotated and stored in the knife handle. In addition, since the folding knife is small after being folded, it is convenient for people to carry it, and the knife body is stored in the knife handle, making it safer to carry Therefore, for users such as divers, field activists, military police, etc., folding knives have a high degree of convenience compared to other knives that cannot be stored.

Generally speaking, if the folding knife is used for a long time, in addition to the dirt and impurities accumulated in the handle, there will also be the problem of the knife body becoming blunt. Therefore, the user usually needs to disassemble the folding knife to be able to remove it. The aforementioned dirt, debris, or take out the knife body for polishing. However, in order to ensure that the user can use the folding knife stably, the industry usually pivots the knife body between the two plates when designing the folding knife. , And then use screws or other components to assemble and fix the two plates into a knife handle. Although this can make it difficult for the user to disperse the knife handle and the knife body due to external forces during the operation of the folding knife However, it will make it difficult for the user to disassemble the folding knife, and the user cannot easily maintain the folding knife.

In order to solve the aforementioned problems, many manufacturers have made improvements to the structure of the folding knife. Here is a brief description. Please refer to Figures 1A~1D. The folding knife 1 is composed of two plate bodies 11A, 11B, a knife body 13 and a brake. A pivoting post 111 is protrudingly provided on one side of the plate 11A adjacent to one end. The top surface of the pivoting post 111 is provided with a first block 113, and the first block 113 and the pivot The posts 111 are retracted to form an embedding groove 1111. In addition, the first block 113 has a rectangular shape and is inclined at an angle (as shown in Figure 1C). The cutter body 13 is opened at a position adjacent to one end. There is a pivot hole 131, the pivot post 111 can extend into the pivot hole 131, so that the cutter body 13 can rotate about the pivot post 111, and one end of the brake 15 is pivoted to One side of the plate 11A is adjacent to the other end, and the top surface of the braking portion 15 adjacent to one end is protrudingly provided with a second block 151. The second block 151 is also rectangular and can follow the braking portion. 15 rotates, and it shrinks with the braking portion 15 to form an embedding groove. In addition, a first opening 112 is formed at a position adjacent to one end of the plate body 11B, and a first opening 112 is formed at a position adjacent to the other end of the plate body 11B. Two openings 114, the first opening 112 and the second opening 114 are respectively rectangular, and the configuration of the first opening 112 matches the first block 113, and the second opening 114 The configuration matches the second block 151. Furthermore, the plate 11B corresponds to the inner wall surface of the bottom of the first opening 112, and is protrudingly provided with an embedding block 1121, which corresponds to the inner wall surface of the bottom of the second opening 114 , There is also another embedding block.

Please refer to Figures 1A to 1D again. When assembling the folding knife 1, the user must first place the plate 11B at a specific angle so that the first opening 112 can be aligned with the first block 113. Correspondingly (as shown in Figure 1B), at the same time, rotate the braking portion 15 so that the second block 151 is formed as shown in Figure 1B, and then the user extends the first block 113 and After passing through the first opening 112 and making the embedding block 1121 correspond to the embedding groove 1111 of the pivoting post 111, the plate body 11B can be rotated so that the second opening 114 can be connected to the second block 1111. The body 151 corresponds to the body 151, and the second block 151 is inserted into and passed through the second opening 114, and the other inserting block is made to correspond to the inserting groove of the braking portion 15, and then the braking portion 15 is rotated again. At this time, the first block 113 and the second block 151 will no longer correspond to the first opening 112 and the second opening 114 (as shown in Figure 1A), and the inserting block 1121 and the other inserting block 1121 The clamping blocks will form an embedded state with the blocks 113 and 151 respectively. Similarly, when the user wants to disassemble the folding knife 1, he must first rotate the braking portion 15 so that the second block 151 corresponds to After the second opening 114, rotate the plate 11B so that the first opening 112 corresponds to the first block 113, so that the plate 11B and the cutter body 13 can be removed in order to clean each component, or It is to replace the knife body 13 with a new one.

However, although the aforementioned folding knife can be disassembled and assembled by the user, in actual use, the following problems will arise: (1) When disassembling or assembling the folding knife, the user must adjust the plates repeatedly and one by one. The position of the components such as the body, the blocks and the braking part, this will obviously cause the steps of disassembling or assembling the folding knife to be too complicated; (2) Since the configurations of the aforementioned blocks and openings are all specific shapes, therefore, The user must carefully adjust the positions of the blocks and the openings so that each block corresponds to the openings before allowing the blocks to pass through the openings. The foregoing process will vainly cause the user to spend too much time on adjustments. The position of the block body and the opening; (3) Since the thickness of each of the inserting blocks must be equal to or slightly smaller than the corresponding embedding groove, only after the plate body and the braking part are rotated, the inserting blocks and the corresponding blocks can be made The body is in an embedded state. Therefore, the industry must control the tolerance to a very small range, otherwise it will cause the folding knife to be unable to be assembled smoothly, resulting in a decline in the industry's production yield; (4) When the user is disassembling or assembling the folding knife , The blocks will inevitably collide with the periphery of the corresponding openings. Over a long period of time, the edges of the blocks or openings will be damaged or deformed. If the aforementioned defects or deformations are serious, it may even cause the When the block and the opening cannot achieve the effect of interlocking, the folding knife cannot be used normally; (5) Since both the block and the opening must be adjusted to the corresponding position, the block can pass through Corresponding to the opening, but when the size of the folding knife is small, the size of each block and the opening will also be small, making it difficult for the user to align each block with the opening, and increasing the user to assemble the folding The difficulty of the knife.

In summary, there are still many shortcomings in conventional folding knives. Therefore, how to design an innovative folding knives with a simple structure that makes users more convenient and safer in use? The manufacturer of folding knives urgently wants to solve one of the important issues.

In view of the fact that the aforementioned folding knife still cannot fully meet the needs of the user, the inventor upholds the research spirit of excellence, and years of practical experience, after a long period of hard research and experimentation, finally developed an invention that can be quickly dismantled And the folding knife assembled is expected to provide users with a more convenient and safe folding knife with the advent of the present invention.
