[0002] As a traditional educational toy, building blocks are deeply loved by people because they can effectively train people's hands-on and thinking abilities. They are especially suitable for children's toys, teaching aids, making decorations or technical purposes. The cultivation of hands-on ability has a promoting effect on the brain development of infants and young children.

[0003] Currently, the connection between building blocks in the building block connection on the market is simple, and the connection structure lacks flexibility, resulting in the overall assembly and installation operations being relatively cumbersome. Summary of the invention

[0004] The purpose of the embodiment of the present invention is to provide a locking assembly, which has the advantages of reasonable structural arrangement and convenient assembly and installation operations.

[0005] To achieve the above-mentioned purpose, an embodiment of the present invention provides a locking assembly, including a first component, a second component, and a connecting structure for connecting and locking the first component and the second component:

[0006] The connection structure comprises a connection piece, the connection piece is rotatably connected to the first component, one end of the connection piece protrudes from the first component and is provided with a clamping block in a cantilevered manner, and a limiting distance is formed between the clamping block and the first component;

[0007] A clamping hole is provided on one side of the second component for the end of the connecting member and the clamping block to be inserted and installed, and a clamping rib is fixed to the opening of the clamping hole in a cantilevered manner. When the connecting member is inserted and installed in the clamping hole, the clamping rib is located within the limiting distance; the clamping hole and the clamping rib are both arranged corresponding to the clamping block;

[0008] The first component is also provided with a positioning structure for positioning the second component when the connecting block is sunk into the clamping hole.

[0009] Compared with the prior art, when connecting and installing the first component and the second component, it is necessary to align the first component and the second component with each other according to the positioning structure, and then insert the snap-in block into the second component through the snap-in hole. At this time, the snap-in rib enters the limit spacing, and then rotate the connecting piece as a whole to rotate the snap-in block above the snap-in rib, so that the snap-in rib is restricted by the snap-in block within the limit spacing, and cooperate with the positioning structure to lock the first component and the second component together. At this time, the snap-in block restricts the snap-in rib from leaving the limit spacing, and the positioning structure restricts the second component and the first component from moving relative to each other. The overall assembly process is extremely simple and has the advantage of better flexibility.

[0010] As an improvement of the above-mentioned scheme, a spring sheet is provided on the connecting member, and a travel groove corresponding to the spring sheet is opened on the first component. When the connecting member is rotated until the spring sheet abuts against one side of the travel groove, the clamping block is corresponding to the clamping hole; when the connecting member is rotated until the spring sheet abuts against the other side of the travel groove, the clamping block is corresponding to the clamping rib, and the clamping block limits the clamping rib from leaving the limiting distance.

[0011] As an improvement of the above solution, the positioning structure includes a positioning block and a positioning hole, the positioning block is fixedly arranged on the first component, the positioning hole is opened in the second component, and when the connecting block sinks into the clamping hole, the positioning block simultaneously sinks into the positioning hole.

[0012] As an improvement of the above solution, the positioning block and the positioning hole are arranged in an interference fit.

[0013] As an improvement of the above solution, two groups of positioning structures are provided.

[0014] As an improvement of the above solution, four clamping blocks are provided along the circumference of the connecting piece.

[0015] As an improvement of the above scheme, the connecting member includes a limiting part and a transmission part, and the clamping block is arranged on the limiting part; a boss is arranged on the outer edge of the limiting part; the boss and the end of the transmission part clamp the first part in the middle to realize the rotational connection between the connecting member and the first part.

[0016] As an improvement of the above solution, the limiting portion is detachably connected to the transmission portion.

[0017] As an improvement of the above solution, the transmission part is provided with a square inner groove at the end away from the clamping block;

[0018] The first component is provided with an operating hole on the side opposite to the side where the connecting member is located, and the operating hole is provided corresponding to the square inner groove.

[0019] As an improvement of the above solution, the first component and the second component are both rectangular building blocks, the interior of the rectangular building blocks is hollow, the connecting member is arranged on one side of the first component, and the transmission part is located inside the first component.

[0020] Other beneficial effects:

[0021] 1. In order to further improve the overall detachability of the structure, the limiting part and the transmission part are detachably connected as a whole. In this solution, the limiting part is detachably connected to the transmission part by screws;

[0022] 2. In order to improve the playability of the building blocks and the overall appearance, the connection structures are all hidden inside the building blocks. In this solution, except for the clamping block component, the other components of the connection structure are all hidden inside the first component. When the first component and the second component are assembled with each other through the connecting piece, since the components are all hidden, an operation hole is opened on the other side of the first component. The user can use a handle or other auxiliary parts to insert them into the direction inner groove through the operation hole, and use the clamping principle similar to the wrench-type fit to drive the overall rotation of the connecting piece to achieve the separation of the clamping block and the clamping rib;

[0023] 3. The setting of the travel groove and the spring sheet limits the overall rotation angle of the connector. Through the positioning limit of the travel groove, the user can know the position state of the clamping block by hand feeling, further improving the overall operability of the structure. Furthermore, in this solution, a convex point is set in the middle of the travel groove, and the convex point is located in the middle of the rotation path of the spring sheet. Through the setting of the convex point, the spring sheet will generate resistance when passing over the convex point, thereby further improving the user's operating feel. At the same time, the setting of the convex point can also improve the stability of the clamping block and play a role in positioning the locking or unlocking state of the clamping block;

[0024] 4. In order to simplify the positioning structure, in this solution, the positioning block is set within the limit spacing, and the positioning hole is a clamping hole. When the clamping block enters the clamping hole, the positioning block is located directly below the clamping block. Therefore, when the clamping block enters the clamping hole, the positioning block is inserted into the clamping hole, thereby achieving the effect of positioning clamping;

[0025] 5. In this solution, in order to improve the rotation smoothness of the clamping block and avoid the clamping block and the clamping hole from getting stuck, a chamfer is provided on the edge of the clamping block. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] As a traditional educational toy, building blocks are deeply loved by people because they can effectively train people's hands-on and brain-powered abilities. They are especially suitable for children's toys, teaching aids, making decorations or technical purposes. The cultivation of hands-on ability has a promoting effect on the brain development of infants and young children. At present, the connection between building blocks in the building block connection on the market is single, and the connection structure lacks flexibility, resulting in the overall assembly and installation operations being cumbersome. Therefore, the present invention proposes a locking component, which has the advantages of reasonable structural setting and convenient assembly and installation operations.

[0035] A locking assembly includes a first component 1, a second component 2, and a connecting structure for connecting and locking the first component 1 and the second component 2. In this embodiment, the first component 1 and the second component 2 are both rectangular building blocks, the interior of the rectangular building blocks is hollow, and a connecting member 3 is used to connect two groups of rectangular building blocks.

[0036] The connection structure includes a connection member 3, which is rotatably connected to the first component 1. One end of the connection member 3 protrudes from the first component 1 and is provided with a clamping block 31 in a cantilevered manner. A limiting distance 32 is formed between the clamping block 31 and the first component 1.

[0037] A snap-in hole 4 is provided on one side of the second component 2 for the end of the connecting member 3 and the snap-in block 31 to be inserted into and installed. A snap-in rib 5 is fixed in a cantilevered manner at the opening of the snap-in hole 4. When the connecting member 3 is inserted into and installed in the snap-in hole 4, the snap-in rib 5 is located within the limiting spacing 32. In order to improve the locking stability of the first component 1 and the second component 2, four snap-in blocks 31 are arranged along the circumference of the connecting member 3, and the snap-in holes 4 and the snap-in ribs 5 are arranged corresponding to the snap-in blocks 31.

[0038] The first component 1 is also provided with a positioning structure for positioning the second component 2 when the connecting block is inserted into the engaging hole 4 .

[0039] It should be noted that, in the present embodiment, when connecting and installing the first component 1 and the second component 2, it is necessary to align the first component 1 and the second component 2 with each other according to the positioning structure, and then insert the snap-fit ​​block 31 into the second component 2 through the snap-fit ​​hole 4. At this time, the snap-fit ​​rib 5 enters the limit spacing 32, and then the connecting member 3 is rotated as a whole to rotate the snap-fit ​​block 31 to the top of the snap-fit ​​rib 5, so that the snap-fit ​​rib 5 is restricted by the snap-fit ​​block 31 within the limit spacing 32, and cooperate with the positioning structure to lock the first component 1 and the second component 2 together. At this time, the snap-fit ​​block 31 restricts the snap-fit ​​rib 5 from disengaging from the limit spacing 32, and the positioning structure restricts the second component 2 and the first component 1 from moving relative to each other. The overall assembly process is extremely simple and has the advantage of better flexibility.
