Abstract
Description
Technical Field
[0001] This utility model relates to toys, and more particularly to a wooden toy insert, belonging to the field of toy technology. Background Technology
[0002] In toys (including building blocks, etc.), many components are made of wood (including pressed wood and wood-plastic composite wood). When designing and processing connecting structures such as holes on these components, due to the inherent characteristics of wood, the connecting structure may partially or completely fail due to deformation, chipping, or other damage at the holes, resulting in the component being discarded. In a set of building toys, the inability of some components often means that the function of the entire toy is limited or unusable. To overcome this situation, industry technicians often insert plastic or metal cylindrical kits into the holes and design connecting structures or mounting components on the cylindrical kits. This method overcomes the problem of easy failure when directly processing connecting structures on wooden components to some extent. However, the cylindrical kits are prone to detachment after installation, especially in environments with large temperature variations. Summary of the Invention
[0003] The purpose of this invention is to overcome the aforementioned problems existing in toy components made of wood and to provide a wooden toy insert.
[0004] To achieve the purpose of this utility model, the following technical solution is adopted: A wooden toy insert includes a cylindrical component, which is cylindrical or polygonal. The cylindrical component includes a cylindrical element with a hollow cavity. A back cover is provided on the rear end face of the cylindrical component. The back cover includes a flat portion located on the rear end face of the cylindrical component. Multiple forward-bent spring pieces are integrally connected to the edge of the flat portion. Suspension pieces are provided on the spring pieces. The periphery of the suspension pieces is a non-closed slit. The root of the suspension piece is integrally connected to the spring piece. The head of the suspension piece is close to the flat portion and sinks radially inward. A flange is integrally provided near the rear of the cylindrical component. The flange protrudes from the cylindrical surface. After the back cover is installed on the cylindrical component, the suspension piece is located in front of the flange.
[0005] Furthermore, multiple forward-bent elastic locking tabs are integrally provided on the edge of the planar portion. The angle between the elastic locking tabs and the planar portion is greater than 90 degrees, and the angle between the elastic locking tabs and the planar portion is greater than the angle between the spring sheet and the planar portion.
[0006] Furthermore; the cylindrical component is cylindrical, the rear end of the cylindrical component is a smoothly transitioned chamfer, the diameter of the planar part is equal to the diameter of the rear end face of the cylindrical component, and the rear end of the spring piece is adapted to the chamfer; the front end of the spring piece is an axial surface perpendicular to the planar part, the inner surface and outer surface of the axial surface are both arc-shaped surfaces, and the suspension piece is located on the axial surface.
[0007] Furthermore, the spring sheet and the elastic locking sheet are spaced apart.
[0008] Furthermore, multiple limiting protrusions are integrally provided on the outer circumferential surface of the cylindrical part, and the limiting protrusions are located between two adjacent spring pieces.
[0009] The positive and beneficial technical effects of this utility model are as follows: In this insert, the back cover can be reliably connected to the cylindrical part. After the back cover is inserted into the corresponding hole on the wooden material element in the direction of the hole, the spring and the elastic locking piece are both subjected to pressure and generate pressure towards the hole wall, so that the insert can be reliably embedded in the hole of the wooden material. The angle design of the elastic locking piece can also form a top claw between it and the hole wall, which abuts against the hole wall to prevent the insert from falling off, so that the insert is reliably attached to the wooden element.

[0012] To more fully explain the implementation of this utility model, implementation examples are provided. These implementation examples are merely illustrative of this utility model and do not limit its scope.
[0013] The present invention will be further explained in detail with reference to the accompanying drawings, in which the following references are made: 1: cylindrical part; 2: rear cover; 3: flat part; 4: spring piece; 5: suspension piece; 6: elastic locking piece; 7: limiting protrusion; 8: flange; 9: chamfer; 10: the rear end of the spring piece that is adapted to the chamfer; 11: axial surface.
[0014] As shown in the attached figure, a wooden toy insert includes a cylindrical component 1, which is cylindrical or polygonal. The cylindrical component includes a tubular element with a hollow cavity. A rear cover 2 is provided on the rear end face of the cylindrical component. The rear cover includes a flat portion 3 located on the rear end face of the cylindrical component. Multiple forward-bent spring pieces 4 are integrally connected to the edge of the flat portion. Suspension pieces 5 are provided on the spring pieces. The periphery of the suspension pieces is a non-closed slit. The root of the suspension piece is integrally connected to the spring piece. The head of the suspension piece is close to the flat portion and sinks radially inward. A flange 8 is integrally provided near the rear of the cylindrical component. The flange protrudes from the cylindrical surface. After the rear cover is installed on the cylindrical component, the suspension piece is located in front of the flange. Multiple forward-bent elastic locking pieces 6 are integrally provided on the edge of the flat part. The angle between the elastic locking piece 6 and the flat part is greater than 90 degrees. The angle between the elastic locking piece and the flat part is greater than the angle between the spring piece and the flat part. The spring piece and the elastic locking piece are spaced apart. Multiple limiting protrusions 7 are integrally provided on the outer peripheral surface of the cylindrical part. The limiting protrusions are located between two adjacent spring pieces.
[0015] In this embodiment, the cylindrical member is cylindrical, and the rear end of the cylindrical member is a smoothly transitioned chamfer 9. The diameter of the flat part is equal to the diameter of the rear end face of the cylindrical member, and the rear end of the spring piece is adapted to the chamfer. 10 shows the part where the rear end of the piece is adapted to the chamfer. Due to the presence of the chamfer, the included angle between the rear end of the spring piece and the flat part is also an obtuse angle. The front end of the spring piece is an axial surface 11 perpendicular to the flat part. The inner surface and outer surface of the axial surface 11 are both arc-shaped surfaces, and the suspension piece 5 is located on the axial surface.
[0016] In this embodiment, the cylindrical component is circular, which is easy to understand. When the cylindrical component is a multi-faceted prism, such as a hexagonal prism, octagonal prism, dodecagonal prism, etc., the technical solution of this insert can still be used. It is only necessary to make the spring piece and the elastic locking piece correspond to the prism face.
