Description

Magnetic connecting piece for assembled toy

Technical Field

The utility model belongs to the technical field of toys, and particularly relates to a magnetic connecting piece for an assembled toy.

Background

CN205252548U discloses a magnetic connecting piece for a construction toy, which comprises a cylindrical base body, wherein a magnet is hidden in the cylindrical base body, and convex teeth radiating in the center are formed on the front end surface of the cylindrical base body; a cavity is formed in the cylindrical matrix, the magnet is hidden in the cavity in a loose fit manner, and the size of the inner space of the cavity is enough to accommodate the magnet to freely overturn in the cavity; the cavity is adjacent to the front end face of the cylindrical substrate; the front end surface of the cylindrical matrix is divided into a central part and an outer ring part, the central part of the cylindrical matrix is a flat round surface so that the cavity is sealed, and the convex teeth of the cylindrical matrix are positioned on the outer ring part; the cylindrical matrix is also sleeved with a circular sleeve, the sleeve is divided into an inner sleeve and an outer sleeve, and the outer sleeve is tightly clamped at the periphery of the inner sleeve.

The structure can realize the attraction between the two magnetic connecting pieces, and can rotate relatively to adjust the posture after the attraction (for example, when the arms and the trunk of the toy doll are spliced, the arms need to rotate), and the stability of the splicing posture can be realized. Because the opposite surfaces of the sleeves of the two magnetic connectors are tightly attached in the rotating process, and the front end surfaces of the cylindrical substrates of the two magnetic connectors are provided with the convex teeth, the cylindrical substrates need to slide back and forth slightly relative to the sleeves so as to adapt to the fluctuation of tooth tips and tooth grooves of the convex teeth and improve the hand feeling during rotation.

However, the applicant has found through practice that the magnetic connection piece still has the problem to be improved: 1. the toy is spliced by a large attractive force, so that the magnet needs to adopt a strong magnetic block with strong magnetism, and according to related standards, the strong magnetic block is a dangerous part which cannot be directly contacted with children; on the other hand, because the attractive force required between the toy components is larger, larger pulling force is generated in the process of repeatedly breaking the two toy components which are mutually attracted, namely, the inner sleeve is pulled out from the outer sleeve along the axial direction; although a buckling structure can be arranged between the inner sleeve and the outer sleeve, the wall of the inner sleeve is a single-layer plastic wall, and the wall of the outer sleeve is also a single-layer plastic wall, when the inner sleeve is pulled outwards by magnetic force, the inner sleeve is easy to deform towards the centripetal direction, the outer sleeve is easy to deform towards the centrifugal direction, so that the buckling structure between the inner sleeve and the outer sleeve can be invalid, the inner sleeve is separated from the outer sleeve, and finally, a strong magnetic block falls out to form danger; 2. the magnetic blocks are enclosed in the inner cavity of the cylindrical matrix, when the two magnetic connecting pieces are spliced together, two layers of plastic sheets are actually separated between the two magnetic blocks of the two magnetic connecting pieces, and the plastic sheets can block magnetic force lines to a certain extent, namely weaken magnetic attraction to a certain extent.

Disclosure of Invention

the inner sleeve comprises an inner sleeve outer wall, an inner sleeve inner wall and an inner sleeve front end face which are connected into a whole, the inner sleeve front end face is in a circular ring shape, and an annular radial gap is reserved between the inner sleeve outer wall and the inner sleeve inner wall; the inner layer wall of the inner layer sleeve is adjacent to the wall of the inner core body, and the outer layer wall of the inner layer sleeve is adjacent to the wall of the outer layer sleeve; the outer sleeve is fixed and is equipped with rear end cap, its characterized in that: the rear end cover of the outer sleeve is also integrally and fixedly connected with a plurality of convex columns, the convex columns are uniformly distributed along the circumferential direction of the outer sleeve, the front end of each convex column is provided with a ratchet hook with a small front part and a big rear part, and the convex columns are clamped in a radial gap between the outer layer wall of the inner sleeve and the inner layer wall of the inner sleeve; the inner surface of the circumference of the outer wall of the inner sleeve is correspondingly provided with a ratchet block in a protruding mode, and the ratchet hooks of each convex column hook the corresponding ratchet block to limit the inner sleeve to move forwards relative to the outer sleeve.

The central part of the front end surface of the inner core body is formed into a hollowed-out hole; the aperture of the hollowed-out hole can not pass through the hollowed-out Kong Weizhun by the magnet block; the convex teeth of the front end face of the inner core body are arranged around the hollowed-out holes.

The utility model has the following advantages and effects:

1. the convex column with the ratchet hook is clamped between the outer layer of the inner layer sleeve and the inner layer of the inner layer sleeve, the outer layer wall of the inner layer sleeve is surrounded by the outer layer sleeve and is not easy to deform in the centrifugal direction to a large extent, and the inner layer wall of the inner layer sleeve is supported by the inner core body in the radial direction to the centrifugal direction so that the inner layer sleeve is not easy to deform in the centripetal direction to a large extent, so that the ratchet hook is difficult to separate from the ratchet block, the inner layer sleeve cannot move forwards relative to the outer layer sleeve, and the strong magnetic block cannot drop out after the inner layer sleeve and the outer layer sleeve are assembled. On the other hand, the front end of the convex column is provided with the ratchet hook with the shape of small front and big back, so that the assembly difficulty of the inner sleeve and the outer sleeve is reduced.

2. The central part of the front end face of the cylinder body is formed into a hollowed hole, so when the two magnetic connecting pieces are spliced together, the two magnet blocks of the two magnetic connecting pieces cannot be separated by two layers of plastics, namely the magnetic force lines of the magnet blocks cannot be blocked from penetrating, and the magnetic attraction force can be greatly enhanced.
