Description

M250993 Four, C-shaped long lock piece with a shape of 4C1C Second slot, creation instructions (1) [Technical field of new type] This creation refers to a kind of stack, especially a type of use of the key hole 2 Point-contact rotation, bending, and breaking. In addition, the thief wants to pry open the lock with a foreign object. [Prior art] Press, the lock structure of the conventional laminated lock is shown in the first figure, and the lock piece (11 ) And the gasket (1 12) are staggered and stacked, and an indentation of an arc (11) is provided on the outer edge of each piece (1 1) inwardly at the formed accommodation hole (111). 11 The notch (1) of the lock core shell (1); and the key (2) is an accommodation hole (1 1 1) that can be 1 1) The two long side end faces must be provided with 2 1 1) positions corresponding to the locks The protruding block (112), and the bottom of the groove (2 1 2 (212) of the groove is in contact with each lock piece (11) at different positions, and the lock piece of the lock core and the key structure of the short side of the key have different depths. The groove and the lock piece, meanwhile, it can make the key difficult to change the hole, so it can be made narrower and more difficult. The heart shell (attached to the lock 2), the lock piece ( The notches (3) where the holes are staggered are inserted in the middle of the notch (3), and the slotted piece (1 long side end) is used to push the arc recess 1 of the lock piece and its core shell (1 and the lock piece (1 1) The position of the (111 protruding block (1 113)) corresponding to the lock core shell key (2 (211 1) container surface and two short using these (11) openings (1 1 key () center 11)) Shape) two-phase 12), and there are different keys (1))), and (11 side end depth 3) — 2) The number of inputs is mostly corresponding to the gasket: For each lock, the grooves that are the same between the multiple levers (1 and 2 slotted levers 1) are different, so that they correspond

Page 5 M250993 4. Creation instructions (2) When the lock lever (14) at the slot (1 3) of the lock core shell (1) is not in use, the entire lock core can be rotated to lock or unlock the laminated lock. action. However, the above-mentioned conventional laminated lock core and key structure still lacks in practical use, such as: 1. Regardless of whether the formed protrusion is located at any periphery of the receptacle, the thief only needs to make the insert. Smaller than the corresponding protrusions on both sides can be smoothly inserted into the receptacle, so when the shape of the insertion piece is simple and easy to place, the higher the ratio of thieves opening the lock, the lower the anti-theft effect that the lock can hold. 2 · Because the key rod of the key is smoothly inserted into the receiving hole of the lock piece of the lock core shell and the lock piece is pushed at different times, a slot must be provided on the two long side end surfaces of the key key rod. And the slotted positions correspond to the locks respectively. ^ The two protrusions of the receiving hole, and the grooves with different depths are cut between the two long-side end surfaces and the two short-side end surfaces. But this will weaken the strength of the key lever and make the key The rod is easily bent, deformed, and broken by force. — Today, the creator is in view of the lack of the above-mentioned knowledge structure. Therefore, based on the spirit and concept of seeking for good, and with the help of professional knowledge and technology, ^ correct and improve the lack of knowledge to study Create this work and provide a structure that can completely improve the shortcomings of the habit. [New content] This creation is about a laminated lock with a lock center, 'the pair of locks in the container hole at a pair of oblique angles corresponding to the different edges of the slope, so as to correspond to the corresponding two The distance between the opposite edges is sequentially generated by a long and short # and its key structure. Three edges are sequentially arranged at the edge of the key structure.

M250993 IV. Creation instructions (3) The distance between the end faces of the two short sides of the lock lever and the distance between the two opposite edges; according to the grooves and the lock plates, the keys are not easy to deform, narrow and small, increasing the thief [Implementation] and Let Benchuang refer to the drawings together and first of all, please refer to the structure, which is related to the lock plate (3 1) and the pad 3 2) corresponding to the central molding lock plate (3 1) with different slopes 3), the third contact edge ( 312). There are grooves with different depths on the surface, and the distance between the two short sides of the lock lever should correspond to the relative tolerance in the locking hole of the lock plate. You can use the holes with different depths on the short side of the key two. As a point-contact turning lock, at the same time, the key can be folded and broken. In addition, the lock hole can be made more difficult to pry open the lock with foreign objects. For the technical drawing number, please refer to the second heart shell (sheet (3 with a shape-forming hole) (the first (31 (31 edges corresponding to the first, second, and third 3 σ), the detailed description of the surgical content ~ fifth 3) In the middle 2), the distance between Rongkong (33 11) and the edge (34), and 3), (the edge (3 is more clearly disclosed, hereafter 1 4) are gradually shortened ( 315), and the establishment positions of each other are 3 3), hereby; following the lock core shell away from the (L 1), () state, and then to the lock plate (and each different slot ((3) a lock plate (, another The open end at the lock 3 3) shows the number of multi-phase lock plates (11), the peripheral edge according to 12), and the two 3 14) 12), L 2), 3 1) and 3 1 ) The heart shell (3 corresponding to the installation site combined with the original composition 3 1) and (321 sequence with three second edges and two pairs of establishments, (313 (L 3) arc notches on the periphery ( ) Is set up-^ lever is a lock pad with anti-drilling lock (), and two by two (31 three against each other) '(Sequentially produce an arc concave 3 15 a notch (34 components (

Fourth, the creation instructions (5) ---------- but different. 'Besides, the arc notch (315) on each lock piece (31) corresponds, and it is the latch lever (3 4) After the corresponding embedding, a lock core can be turned to perform the unlocking or locking action. ^ Through the above implementation description, we can know that the structure of this creation and the familiar phase have many advantages, such as: Compared with 1 · Because the key of the key of this creation is flat and wavy, the anti-drilling element and lock The shape of the hole in the film can be made narrower to make it difficult for a thief to use the unlocking device. 2. In addition, because the groove on the key is set on the corresponding end of the short side of the lock lever 2, the lock lever can have better strength, and it is not easy to be shaped or broken. To sum up, this creative embodiment can indeed achieve the expected use effect, and the specific structure disclosed has not only been seen in similar products, nor has it been disclosed before the application. It has fully complied with the provisions of the Patent Law. And request '爰 to file a new patent application in accordance with the law, please beg for review and grant the patent, then the real sense is 0 便
