TECHNICAL FIELD

The present invention relates to the field of toy technologies, specifically to a magnetic crane and a magnetic tile toy including such magnetic crane.

BACKGROUND

A magnetic toy refers to a toy with magnets or magnetic components. Popular magnetic toy products on the market have magnetic tile toys, magnetic clay (magnetic mud), and the like, which can be shaped into any form through combination and attraction. The magnetic tiles, also called “magnetic building blocks”, are a type of toy for early childhood education from the United States. The magnetic tiles are mainly used for building magnetic geometric shapes with a variety of colors in two dimensions or three dimensions.

The magnetic tiles are spliced together through magnetic attraction to form various shapes, which helps develop children's imagination. The cross-sectional shapes of the magnetic tiles are typically triangles, quadrangles, and the like. The magnetic tiles in these shapes are spliced together to create various structures. However, this method of splicing magnetic tiles provides limited play options with a relatively simple structure, which easily causes children to lose interest. Therefore, there is a need for a magnetic toy that can be used with magnetic tiles to enhance children's play enjoyment.

SUMMARY

An objective of the present invention is to provide a magnetic crane and a magnetic tile toy including such magnetic crane to resolve the above problem in the background.

To resolve the above technical problem, the technical solution used in the present invention is as follows:

A magnetic crane is provided, including a base, a hollow limiting assembly, a lifting assembly, a swing arm, and a magnetic suction assembly. A second magnet block is mounted on an inner side of the base, the base is rotatably connected with a turnplate at a center, a U-shaped support frame is fixed on the turnplate at a center, the hollow limiting assembly is rotatably connected via a first positioning pin in a U-shaped groove of the U-shaped support frame, the lifting assembly is inserted into a cavity in the middle of the hollow limiting assembly, the swing arm is rotatably connected to a top portion of the lifting assembly via a positioning pin, a bottom portion of the swing arm is rotatably connected to the magnetic suction assembly via a second positioning pin, and a first magnet block is mounted below in the magnetic suction assembly. The hollow limiting assembly rotates around the first positioning pin as a fulcrum. The lifting assembly can move within the cavity inside the hollow limiting assembly, so as to extend or retract. The turnplate can rotate 360° on the base. The swing arm and the limiting rib plate of the lifting assembly are connected via a positioning pin, allowing rotation around the positioning pin as a fulcrum. As the second magnet block is mounted on an inner side of the base, the base can be attracted to another magnetic tile.

Preferably, the hollow limiting assembly includes a left hollow shell and a right hollow shell, the left hollow shell and the right hollow shell are joined and screwed to each other, and bottom portions of the left hollow shell and the right hollow shell are disposed in the U-shaped groove of the U-shaped support frame. Positioning pins are fixed above and below the left hollow shell, and the right hollow shell and the positioning pin are joined and screwed to each other.

Preferably, the bottom portions of the left hollow shell and the right hollow shell are uniformly fixed with second limiting teeth, and a bottom of the U-shaped groove of the U-shaped support frame is uniformly fixed with first limiting teeth.

Preferably, the second limiting teeth mesh with the first limiting teeth. The second limiting teeth do not fully mesh with the first limiting teeth under the action of the first positioning pin, leaving some gaps between the meshing points. Both the second limiting teeth and the first limiting teeth are made of plastic, so the hollow limiting assembly can be turned over with a certain amount of force relative to U-shaped support frame.

Preferably, the lifting assembly includes an elevating frame and a limiting rib plate, a top portion of the elevating frame is fixedly connected to a bottom portion of the limiting rib plate, two sides of a bottom portion of the elevating frame are each provided with a plastic snap fastener, and the plastic snap fastener abuts in a limiting hole provided in the hollow limiting assembly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention is further described below in detail with reference to the embodiments.

As shown in FIG. 1, the present invention provides a magnetic crane, including a base 1, a hollow limiting assembly 3, a lifting assembly, a swing arm 6, and a magnetic suction assembly. A second magnet block 101 is mounted on an inner side of the base 1, and the base 1 is rotatably connected via a turnplate 201 at a center. The turnplate 201 is clamped to the base 1 via protrusions on its bottom circumference. A U-shaped support frame 2 is fixed above the turnplate 201 at a center, and the turnplate 201 allows the U-shaped support frame 2 to achieve 360° rotation. The U-shaped support frame 2 is rotatably connected to the hollow limiting assembly 3 via a first positioning pin 304. The first positioning pin 304 is mounted on the U-shaped support frame 2. The lifting assembly is inserted into a cavity in the middle of the hollow limiting assembly 3. A top portion of the lifting assembly is rotatably connected to the swing arm 6 via a positioning pin, and a bottom portion of the swing arm 6 is rotatably connected to the magnetic suction assembly via a second positioning pin 701. A first magnet block 9 is mounted below in the magnetic suction assembly.

As shown in FIGS. 2 and 3, the hollow limiting assembly 3 includes a left hollow shell 301 and a right hollow shell 302. After the left hollow shell 301 is inserted into the positioning pin of the right hollow shell 302, it is fixed by tightening screws. The bottom portions of the left hollow shell 301 and the right hollow shell 302 are uniformly fixed with second limiting teeth 303. The bottom of the U-shaped groove of the U-shaped support frame 2 is uniformly fixed with first limiting teeth 202. The second limiting teeth 303 and the first limiting teeth 202 mesh with each other. Under the constraint of the first positioning pin 304, the second limiting teeth 303 are kept at a certain distance from and do not fully mesh with the first limiting teeth 202. Additionally, since both the first limiting teeth 202 and the second limiting teeth 303 are made of plastic, the hollow limiting assembly 3 can be rotated with a certain amount of torque, causing the first limiting teeth 202 and the second limiting teeth 303 to engage or disengage, thereby allowing the hollow limiting assembly 3 to rotate while ensuring stability and preventing automatic rotation when an object is lifted.

Further, a second magnet block 101 is mounted on an inner side of the base 1. The second magnet block 101 allows the crane toy to be attracted to a magnetic tile 10 of another structure, thus providing diverse play options.

As shown in FIG. 2, the lifting assembly includes an elevating frame 4 and a limiting rib plate 5. The top portion of the elevating frame 4 is fixedly connected to the bottom portion of the limiting rib plate 5. The elevating frame 4 is slidingly arranged in the cavity in the middle of the hollow limiting assembly 3. The limiting rib plate 5 is rotatably connected to the swing arm 6 via a positioning pin.

Further, the middle of the elevating frame 4 is hollow, and two opposite surfaces near the bottom of the elevating frame 4 are provided with plastic snap fasteners 401. The plastic snap fastener 401 has a cylindrical head that, when subjected to extrusion force, enters the cavity in the middle of the elevating frame 4. The left hollow shell 301 and the right hollow shell 302 are both provided with limiting holes 305 that match the cylindrical heads. There are multiple limiting holes 305, and a flange is fixed around the circumference of each limiting hole 305. When a child pulls the elevating frame 4 outward, the cylindrical head is extruded by the flange to enter the cavity in the middle of the elevating frame 4. Once released, the cylindrical head pops out (due to the elasticity of the plastic structure) and enters the limiting hole 305, achieving engagement. To make a switch to another limiting hole 305, greater force is needed to pull the elevating frame 4 outward.

Further, limiting plates are fixed on both sides of the bottom of the elevating frame 4 adjacent to the plastic snap fasteners 401. The width of the top opening of the hollow limiting assembly 3 is greater than the width of the elevating frame 4. When the limiting plates approach the top opening of the hollow limiting assembly 3, they limit the movement of the elevating frame 4, preventing it from being pulled out of the cavity of the hollow limiting assembly 3.

As shown in FIGS. 1 and 2, one end of the limiting rib plate 5 has a U-shaped opening, within which the swing arm 6 is rotatably arranged via a positioning pin. The bottom of the swing arm 6 away from the limiting rib plate 5 has a round hole. The magnetic suction assembly includes a right shell 7 and a left shell 8. A second positioning pin 701 is fixed at the center of the inner wall of the right shell 7 and penetrates the round hole to connect with the left shell 8. The second positioning pin 701 has a screw hole. After the right shell 7 and the left shell 8 are joined, screws are driven into the second positioning pin 701 for fixing. Once connected via the second positioning pin 701 and the round hole, the right shell 7 and the left shell 8 can rotate on the swing arm 6. After the right shell 7 and the left shell 8 are joined, they are fixed by ultrasonic welding.

Further, cavities for placing the first magnet block 9 are provided in the right shell 7 and the left shell 8 at the bottom. Before the right shell 7 and the left shell 8 are joined, the first magnet block 9 is placed into the cavity. The first magnet block 9 can be used to attract other magnetic tiles 10 of any shape.

As shown in FIG. 5, a magnetic tile toy including such magnetic crane is provided. The second magnet block 101 in the base 1 of the magnetic crane included by the magnetic tile toy can attract other multiple magnetic tiles 10, to fix the entire the crane toy. Children can manually rotate the swing arm 6, causing the first magnet block 9 in the right shell 7 and the left shell 8 to attract other magnetic tiles 10 of any shape, and pull the elevating frame 4 longer, to lift the magnetic tiles 10. The base 1 and a regular square magnetic tile 10 are in the same size.

The following specifically describes the operation principles of the magnetic crane and the magnetic tile toy including such magnetic crane.

As shown in FIGS. 1 to 5, first, the base 1 is attracted and connected to multiple magnetic tiles 10 via the second magnet block 101. Then, the first magnet block 9 in the magnetic suction assembly attracts magnetic tiles 10 of any shape. Based on children's play needs, the hollow limiting assembly 3 is arbitrarily rotated until a suitable play angle is adjusted, and the elevating frame 4 can be extended from or retracted into by a length the hollow limiting assembly 3, causing the limiting rib plate 5 to drive the swing arm 6 and the magnetic suction assembly to ascend or descend. The hollow limiting assembly 3 can achieve 360° rotation via the turnplate 201, thereby enabling the transportation of the magnetic tiles 10. This provides more play options of the magnetic tiles 10 and enhances children's play enjoyment.
