Technical Field
[0001] The invention relates to the technical field of toys, and in particular to an educational toy, a locking method and an unlocking method for improving the fun of unlocking. Background Art
[0002] Educational toys are designed to develop intelligence, increase wisdom, and promote the overall development of users through games and interactive processes. For example, the nine-ring puzzle, tangram, and Huarongdao are all designed based on the principles of mathematics, physics, and logical thinking. These toys not only test the user's spatial imagination and logical reasoning ability, but also promote physical functions such as hand-eye coordination through hands-on operation.
[0003] Although there are many types of educational toys on the market, their appearance design is relatively simple and conservative, lacking innovation and diversity. They are often limited to traditional geometric shapes, such as simple squares, circles or strips, lacking novel elements that can arouse users' strong interest. In addition to the monotonous shapes, some educational toys are also relatively boring in terms of gameplay design and interactivity. They may only rely on traditional game modes such as simple jigsaw puzzles, sorting or puzzle solving, lacking novel and interesting challenges and changes. This lack of innovative gameplay design can easily make users feel bored and difficult to maintain interest and participation for a long time. Summary of the invention
[0004] In order to solve the shortcomings of existing educational toys such as monotonous shape and low interest, the present invention proposes an educational toy, which consists of a lock box and three keys. The three keys are stacked and inserted into the lock box, and the insertion and withdrawal movement of the keys is restricted by the lock mouth. The user must constantly adjust the position of the keys to successfully unlock and remove the three keys from the lock box. The matching mode of the lock box and the keys is completely different from that of existing educational toys, and the shape is novel and the interest is high.
[0005] The technical solution adopted by the present invention is to design an educational toy, comprising: three keys and a lock box for accommodating the three keys; the key has a key head and a key handle, one side of the key head is provided with convex teeth arranged at intervals along its length direction, and the other side is provided with grooves corresponding to the convex teeth, the convex teeth and grooves corresponding to each other on the same key head are a key tooth, and the key heads of the three keys have different shapes; the lock box is provided with a rectangular through hole, the rectangular through hole has two first limiting surfaces in opposite positions and two second limiting surfaces in opposite positions, a first spacing is provided between the two first limiting surfaces to form a movable channel, and the movable channel just allows the key heads of the three keys to be inserted and pulled out after being stacked; the two second limiting surfaces are provided with a pair of wedge-shaped protrusions facing oppositely to form a lock opening, the lock opening blocks any key from being pulled out or inserted into the movable channel in a straight line direction, and the narrowest part of the lock opening allows each key tooth to pass through.
[0006] Furthermore, a head tooth is provided on one side of the end of the key head and a guide inclined surface corresponding to the head tooth is provided on the other side. When the key is inserted into the movable channel and the guide inclined surface moves in contact with the wedge-shaped protrusion, the head tooth just passes through the lock opening; wherein any protruding tooth on the key head is smaller than the head tooth.
[0007] Furthermore, the heights of the protruding teeth on the same side of the key head are not completely the same.
[0008] Furthermore, the key heads of the three keys have the same length, and the head teeth and guide slopes of the three keys are also the same; when the head teeth and guide slopes of the three keys are aligned and stacked, the convex teeth of the three keys are staggered.
[0009] Furthermore, at least one of the three keys has a different number of protruding teeth from the other keys.
[0010] Furthermore, the three keys are the first key, the second key and the third key, the second key is clamped between the first key and the third key, the side of the second key facing the first key is the front side, and the side of the second key facing the third key is the back side; the front side of the second key is provided with a positive limit groove arranged along the length direction, and the back side is provided with a back limit strip corresponding to the positive limit groove, the first key is provided with a positive limit strip located in the positive limit groove, and the third key is provided with a back limit groove for accommodating the back limit strip; wherein the bottom of each groove is a plane, so that the key teeth can move in a straight line along the groove after passing through the lock mouth.
[0011] Furthermore, the handle of the second key is larger than the first key and the third key. When the three keys are aligned and stacked, the handle of the second key exceeds the first key and the third key.
[0012] Furthermore, the two first limiting surfaces are both provided with hollow windows for observing the lock opening.
[0013] Compared with the prior art, the present invention comprises a lock box and three keys, which are stacked and inserted into the lock box. A lock opening is arranged in the lock box, and the lock opening is utilized to increase the difficulty of unlocking and locking. The narrowest part of the lock opening allows each key tooth to pass through. After the key tooth passes through, the key needs to be adjusted obliquely so that the next key tooth can be aligned with the lock opening. In this folding line manner, the key can be pulled out or inserted into the movable channel. The matching mode of the lock box and the key is completely different from that of the existing educational toys, and the shape is novel and interesting. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0022] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this patent and are not used to limit the present invention.
[0023] like Figures 1 to 3 As shown, the educational toy proposed by the present invention includes three keys 1, 2, 3 and a lock box 4. The three keys 1, 2, 3 and the lock box 4 are all made of metal, which has higher hardness and is not easy to deform, thereby ensuring the difficulty of unlocking while optimizing the appearance texture of the educational toy. The three keys 1, 2, 3 can be stacked in the lock box 4. The structures of the three keys and the lock box are respectively introduced below.
[0024] Taking the marking of one of the keys as an example, the key has a key head 10 and a key handle 20. The key head 10 is in a long strip shape. The key handle 20 is connected to one end of the key head 10 to facilitate the user to hold and push the first key 1 to move. One side of the key head 10 is arranged with convex teeth 100 at intervals along its length direction, and the other side is arranged with grooves 200 corresponding to the convex teeth 100. The convex teeth 100 and grooves 200 corresponding to each other on the same key head 10 are a key tooth. The shapes of the key heads of the three keys 1, 2, and 3 are all different.
[0025] The lock box 4 is provided with a rectangular through hole, which has two first limiting surfaces and two second limiting surfaces in opposite positions. A first spacing is provided between the two first limiting surfaces to form an active channel 41, which allows the key heads of the three keys 1, 2, and 3 to be inserted and pulled out after being stacked; the two second limiting surfaces are provided with a pair of wedge-shaped protrusions 42 facing oppositely to form a lock opening 43, which blocks any key from being pulled out or inserted into the active channel 41 in a straight line direction, and the narrowest part of the lock opening 43 allows each key tooth to pass through. In other words, after a key tooth passes through, the key must be adjusted obliquely to align the next key tooth with the lock opening, so that the key can be pulled out or inserted into the active channel 41 in a broken line manner.
[0026] In some feasible embodiments of the present invention, the other end of the key head 10 (i.e., the end away from the key handle) is provided with a head tooth 300 on one side and a guide slope 400 corresponding to the head tooth 300 on the other side. When the key 1, 2, 3 is inserted into the movable channel 41 and the guide slope 400 moves in contact with the wedge-shaped protrusion 42, the head tooth 300 just passes through the lock opening 43. Any convex tooth 100 on the key head 10 is smaller than the head tooth 300, and the heights of the convex teeth 100 on the same side of the key head 10 are not completely the same. Designing the size of the head tooth 300 to be larger can increase the difficulty of the key 1, 2, 3 to escape from the lock box, and the convex teeth 100 having different heights can confuse the user, and the user needs to try to move the key repeatedly to find a pattern, which effectively improves the fun.
[0027] In some feasible embodiments of the present invention, the key heads 10 of the three keys 1, 2, and 3 have the same length, and the head teeth 300 and the guide slope 400 of the three keys 1, 2, and 3 are also the same. When the head teeth 300 and the guide slope 400 of the three keys 1, 2, and 3 are aligned and stacked, the convex teeth of the three keys 1, 2, and 3 are staggered. In addition, the number of convex teeth of at least one of the three keys 1, 2, and 3 is different from that of the other keys. Differentiating the design of the three keys 1, 2, and 3 can increase the difficulty of unlocking. Not only does the moving position of each key need to be repeatedly adjusted, but the number of keys moved each time and the relative direction also need to be carefully considered. The user must have good logical reasoning and hands-on skills to successfully complete the unlocking.
[0028] Based on the above embodiment, the three keys 1, 2, and 3 are respectively the first key 1, the second key 2, and the third key 3. The second key 2 is clamped between the first key 1 and the third key 3. The side of the second key 2 facing the first key 1 is the front side, and the side of the second key 2 facing the third key 3 is the back side. The front side of the second key 2 is provided with a positive limit groove 21 arranged along the length direction, and the back side is provided with a back limit strip 22 corresponding to the positive limit groove 21. The first key 1 is provided with a positive limit strip 11 located in the positive limit groove 21, and the third key 3 is provided with a back limit groove 31 for accommodating the back limit strip 22. Under the action of the limit grooves and the limit strips, the three keys 1, 2, and 3 are linked to each other, and the key must be adjusted so that the key teeth are aligned with the lock 43.
[0029] On this basis, the bottom of the groove 200 of all keys is flat, and space is reserved for the key to move in a straight line through this plane, so that after the key teeth pass through the lock mouth 43, they can still move in a straight line along the groove 200 for a distance. This distance is the length of the bottom of the groove 200 along the length direction of the key, so that the three keys 1, 2, and 3 have a larger range of movement, avoiding jamming during movement and improving the operating feel.
[0030] In some feasible embodiments of the present invention, the handle 20 of the second key 2 is larger than the first key 1 and the third key 3. When the three keys 1, 2, and 3 are aligned and stacked, the handle 20 of the second key 2 exceeds the first key 1 and the third key 3. Since the second key 2 is clamped between the first key 1 and the third key 3, the handle 20 of the second key 2 is larger to facilitate the user to hold and push the second key 2, and each key can be conveniently operated and moved during the unlocking or assembly process.
[0031] In some feasible embodiments of the invention, the two first limiting surfaces are both provided with a hollow window 44, through which the wedge-shaped protrusion 42 can be observed. The user can observe the matching relationship between the key teeth and the lock mouth 43 during the process of moving the key, find the correct moving path, and stimulate interest in unlocking.
