Description

TECHNICAL FIELD

[0001] The utility model relates to a spliced toy, especially to a ring segment connecting piece in toy splicing and belongs to the technical field of toys. BACKGROUND

[0002] In the spliced toy, the ring connecting piece is a commonly used element, and a whole ring is commonly seen, but if a part of the ring is needed (i.e. a ring segment, referring to a part of the ring), the whole ring needs to be cut open, and a connecting structure is designed on the end face of the cut open part. The common connecting structures, such as the plug-in hole and the mortise and tenon joint, have limitations when used at both ends of the ring segment. Because the ring segment itself is arc-shaped, the rod also needs to be arc-shaped if the rod plug-in is used, which is inconvenient for plug-in of the arc-shaped rod. Although the mortise and tenon joint can be used for end face clamping, it is difficult to achieve multi-angle adjustment, which brings limitations to model transformation and imagination development.

[0014] The magnet cavity assembly comprises an outer sleeve 3, an inner sleeve 4 which is gap-fitted in the outer sleeve, the inner sleeve has an axial shoulder 7 at the front of the sleeve, the rear end surface of the axial shoulder has a ring of teeth A 8, the front end surface of the inner sleeve has a ring of teeth B 9 which can engage with the teeth A, the two side surfaces of the teeth A and the teeth B are both inclined surfaces, the teeth B can rotate relative to the teeth A under the action of a circumferential torsion force, the teeth of the teeth B jump between the teeth of the teeth A when rotating, the teeth B rotate along the teeth A, the front end surface of the inner sleeve has a plurality of axially extending long teeth 5, in this embodiment, there are six long teeth which are evenly distributed around the inner sleeve, the inner surface of the long teeth is a radially inwardly extending curved surface 6 from the rear to the front, the curved surface facilitates the flipping and attraction of the magnet, the size of the opening formed by the six long teeth is less than or equal to the diameter and height of the magnet, the magnet cannot escape from the opening, the long teeth are in a cantilever state, the long teeth can be made of plastic, the diameter of the circle enclosed by the front end of the long teeth is less than or equal to the diameter and height of the cylindrical magnet, in actual design, the minimum diameter of the chamfered end can be slightly smaller than the diameter of the circle enclosed by the protrusion, so that the chamfered end can come out of the opening under the action of the magnetic attraction force, and the two magnets on the two connecting members can be attracted together, the long teeth of the two inner sleeves are relatively staggered and can be inserted into each other between the long teeth of the other, the size of the cavity of the inner sleeve is greater than the size of the cylindrical magnet in any direction, the magnet can be flipped in any direction in the cavity of the inner sleeve, after the inner sleeve is fitted in the outer sleeve, the teeth A and the teeth B are in surface-to-surface contact, and the long teeth extend out of the outer sleeve, as shown in Figure 2 、 Figure 3

When the magnet assemblies on different connecting members approach each other, the long teeth on one element (connecting member) are inserted between the long teeth on the other element, and due to the repulsion between same-polarity objects and the attraction between different-polarity objects, the magnets automatically rotate to two different poles and then can be attracted together. After being attracted, the teeth B are forced to be in contact with the teeth A, and due to the attraction of the magnets, the angle between the two elements can be relatively positioned. When the angle needs to be adjusted, the two elements are relatively rotated, the long teeth on the element are driven by a circumferential torsion force to make the teeth of the teeth B jump between the teeth of the teeth A, thereby achieving angle adjustment. After the adjustment is completed, the teeth B and the teeth A are relatively engaged together to relatively position the angle between the two elements (connecting members).
