Description

Technical Field

[0001] The invention relates to an intellectual toy, in particular to an intellectual puzzle toy and a method for assembling spherical parts of the puzzle toy. Background Art

[0002] The inventor invented two patents in 2017 and 2019, with patent numbers: 201721164414.3 and 201920193388.X. After practicing these two patents, the inventor found many problems. The 2017 assembly contains a round-headed universal knot. After making a sample, the inventor found through repeated experiments that this round-headed universal knot is not practical at all and there is no need for it to exist. After installation, due to errors such as molds, the assembled model will also be deformed. In addition, the spherical parts in this patent can only extend in five directions and cannot meet the needs of various situations. The 2019 patent is mainly aimed at the improvement of the connector, which is reflected in the one-way opening design. This kind of slot is mainly to meet the easy plug-in and unplug connection between the connector and the spherical part, even children can easily plug and unplug; and the connection between the connector and the spherical part is stubborn and not easy to loosen. However, we found that in order to achieve the above purpose, one of the openings must be opened through the annular convexity, or the distance before the annular convexity must be lengthened, which will inevitably increase the size of the sphere, thereby bringing a series of problems. Therefore, to achieve the above purpose, in the prior art, the only way is to increase the opening distance.

[0003] In addition, the spherical parts of the above two patents have a fatal flaw, that is, if the manufacturing material is plastic, that is, injection molding. In order to ensure the internal structure of the sphere, the sphere needs to be made into two halves and then spliced. In order to facilitate splicing, industrial production adopts the method of making two halves of the sphere, one half with a jack on the butt surface and the other half with a plug, and then splicing them by machine. However, this creates a problem, that is, there are injection points on the surface of the sphere. Once formed, no matter how it is treated, it cannot be planed perfectly. Summary of the invention

[0004] The purpose of the present invention is to provide a puzzle toy, aiming to solve the technical problem in the prior art that the surface of the spherical part is not smooth due to injection molding.

[0005] In order to solve the above problems, the present invention designs a hemisphere based on the original ball, with each hemisphere having at least one plug post and a corresponding socket. The socket and the plug post cooperate with each other, and the injection port of the hemisphere is located on a plug post of the hemisphere. The plug posts on one hemisphere correspond to and are inserted into the sockets on the other hemisphere to form a spherical part, and a plurality of connecting holes are arranged on the outer periphery of the spherical part; connected to the connecting holes is a connecting part, and a plurality of connecting posts are arranged on the main body of the connecting part, and the connecting posts are provided with a straight opening, which divides the connecting posts into two semicircles. A circular elastic space is provided at the bottom of the straight opening; the injection port of the connecting part is located at the root of a connecting post of the connecting part;

[0006] The biggest advantages of this design are:

[0007] For spherical parts, the original sockets and plugs are made on two hemispheres respectively, and the sockets and plugs are placed on one plug at the same time. In this way, one set of molds can be saved. However, if it is simply changed in this way, there will be a problem. We don’t know how to install it, because it is not just one or two things. We can install it manually. With so many spherical parts, 100,000 pieces need to be injection molded in one day and one night, which is impossible for people to install. Therefore, although it is known in the prior art that a mold can be saved, such a hemispherical structure will still not be adopted. And the injection port is designed to be located on a plug of the hemisphere. The injection point (defect) of the hemisphere formed by injection molding is located on a plug of the hemisphere, and it is inserted into the corresponding socket together with the plug, so that the spherical part is flawless as a whole.

[0008] For the connector, in order to ensure that the connecting column can be inserted into the connecting hole and has elasticity, the prior art designs the straight opening to be thin and long, and even extends to the connector body, which makes it impossible to set the injection port position on the connecting column.

[0009] In this solution, a circular elastic space is provided at the bottom of the straight opening. While ensuring that the connecting column can be inserted into the connecting hole and has elasticity, the length of the straight opening can be shortened a lot, and only about half of the connecting column needs to be opened. In this way, the injection port position can be set at the root of the connecting column, staggering the straight opening. By adopting this solution, the injection point (defect) of the injection-molded connector is located at the root of the connecting column, and is inserted into the connecting hole together with the connecting column, so that the overall model structure is flawless.

[0010] The connecting piece body is in the shape of a straight line, a T-shape, a cross shape, a 90-degree elbow or a U shape, and each end thereof is provided with a connecting column, and a connecting platform is provided at the bottom of the connecting column.

[0011] The puzzle toy also includes a round piece, the round piece includes a connecting hole, the connecting end of the connecting piece is movably matched and plugged with the connecting hole of the round piece; a plurality of round pieces, a plurality of spherical pieces and a plurality of connecting pieces are connected to form a model structure;

[0012] The model structure is in the shape of an airplane.

[0013] The spherical part is evenly provided with four circular holes, which are evenly distributed around the spherical part in a circle, and one circular hole is a connecting hole; and the two hemispheres divide the circular hole equally.

[0014] The above technical solution is further improved. A release space is provided at the center of the spherical part, and the release space is directly connected to the connection hole on the spherical part; the connection end on the connection part, that is, the outer top edge of the two semicircles on the connection column, is provided with a boss, and the boss passes through the connection hole to enter the release space. If the release space is provided at the center of the sphere, it is required that the length of the plug column just passes through the insertion hole, so that the boss on the top enters the release space, so that it opens under the action of elasticity and buckles the inner wall of the release space to play a fixing role. Such a design can fix the plug column once, or it can be designed as a solution for repeated use. At this time, it is only required to set a groove or a pull-back slope on the inner wall of the release space where the boss is clamped. The effect produced by this is that when the connection part is first inserted, the elastic part goes from a closed to a released process, so that the user can clearly perceive that the insertion is in place. At the same time, the design space is large, that is, it can be set as a fixed connection or a movable connection.

[0015] The above technical solution is further improved, and the hemisphere has two plug posts and two plug holes, which are arranged at four corners, and the two plug posts and two plug holes are spaced or continuous. This design not only solves the above technical problems of saving mold and avoiding the exposure of injection port, but also achieves stable connection.

[0016] The above technical solution is further improved. The connection hole of the spherical part does not have a platform edge, which matches the connection platform of the connection column. The connection part extends from the connection platform to the main body of the connection part with a certain taper. The spherical surface has a certain slope. When connected with the connection part, the two must be in complete and close contact. The circumference of the connection hole needs to be set as the connection platform, otherwise the two can hardly match completely. Of course, if they must match, there is a way, but the solution is too complicated. Since most of the connection parts are column-mounted, in order to reflect the beauty of the curvature, the connection parts are extended from the connection platform to the main body of the connection part with a certain taper. Only in this way can the things spliced ​​together have beauty.

[0017] The above technical solution is further improved, the middle part of the plug post is provided with a clamping piece; the socket is provided with a slot that cooperates with the clamping piece. The spherical piece is always an independent component in actual use, so it is generally not opened, so the clamping piece and the slot are provided to form a fixed connection that cannot be unplugged once inserted.

[0018] Another object of the present invention is to provide a method, which can install the above-mentioned hemisphere through mechanized equipment.

[0019] We know that from the above introduction, this is an intellectual puzzle toy. In the actual puzzle, a large number of spherical bodies will be needed. Since these spherical bodies are made of two hemispheres, we need to think about how to achieve large-scale mechanical puzzle. For the existing technology, due to the use of two pairs of molds, the generated hemisphere has only a jack on one side and only a pin on the other side. In this way, the two hemispheres can be separated, placed on the mold plate, and then the two sides can be pressed together to complete the puzzle. However, since the hemisphere of the aforementioned scheme is a single hemisphere made of a pair of molds, that is, there are both jacks and sockets on the connecting plane of the hemisphere. If the two hemispheres are to be spliced, the problem of alignment must be considered. Then, in order to facilitate alignment, this method requires the hemisphere to adopt a double pin and double jack scheme. And this symmetrical design scheme, we only need to use the properties of the bottom circle of the hemisphere to rotate around the center of the ball to achieve its positioning, so how can a large number of hemispheres with different pins facing the same direction be adjusted? We only need to turn one of the pins to the specified position, and the overall spherical symmetry setting will be consistent.

[0020] According to the above ideas, the scheme adopted by the present invention is: a method for assembling spherical pieces of the above-mentioned puzzle toys, using two mold plates, each mold plate is provided with a plurality of semicircular grooves, the semicircular grooves on the same mold plate are arranged in a matrix, and the mold plate is horizontally rotated 90° or 180°, and the distribution position of the semicircular grooves thereon remains unchanged, each mold plate is provided with a plurality of center columns, the center columns on the same mold plate correspond one to one and are placed in the semicircular grooves on the same mold plate, the two mold plates are molded together, and the semicircular grooves thereon correspond one to one and close together to form a spherical space for accommodating spherical pieces; the assembly method comprises the following steps:

[0021] 1) Place several hemispheres on two mold plates, filling the semicircular grooves on each mold plate; place the hemispheres in the semicircular grooves on the mold plates, with the spherical surface of the hemispheres facing downward, and the plug posts and plug holes on the hemispheres facing upward, and insert the center posts on the mold plates into the center holes on the hemispheres in the corresponding semicircular grooves on the two mold plates;

[0022] 2) Adjust the positions of the hemispheres on the two mold plates in turn, and rotate the hemispheres around the central column, so that the pins and holes on the hemispheres on the two mold plates are finally located at the same position;

[0023] 3) First, rotate one of the mold plates horizontally by 90° or 180° (when the hemisphere has two pins and two sockets, the two pins and two sockets are located at four corners, and the two pins and two sockets are spaced apart, rotate 90°; when the hemisphere has two pins and two sockets, the two pins and two sockets are located at four corners, and the two pins and two sockets are continuous, rotate 180°), then close the two mold plates, and splice and connect the hemispheres in the corresponding semicircular grooves on the two mold plates to form a spherical part;

[0024] 4) The two mold plates are opened, and the spherical parts formed by the splicing connection are removed.

[0025] The center column is conical and has an opening at the upper end; the direction-adjusting machine is composed of a transmission device and a direction-adjusting gate; the transmission device carries the cutting mold plate forward and passes through the direction-adjusting gate, and the direction-adjusting gate is horizontally mounted on the transmission device, on which are provided a plurality of cylindrical levers, the number of which corresponds to the number of hemispheres; the mold plate passes under the lever, and the outer edge of the lever is tangent to the center ball hole of the hemisphere; the bottom of the lever is higher than the plane of the hemisphere; when the socket on the hemisphere hits the lever, the hemisphere will rotate with the center column, so that all hemispheres passing through the direction-adjusting gate have the same orientation.

[0026] In view of the fact that there are two plug posts and two plug holes on the hemisphere, the two plug posts and the two plug holes are arranged at four corners, and the two plug posts and the two plug holes are spaced apart (so that the two plug posts are opposite to each other and must be arranged at two sides, one of the plug posts must touch the cylindrical baffle rod, and there will be no phenomenon that the two plug posts are clamped on both sides of the cylindrical baffle rod), a direction adjustment machine is designed to adjust the direction of the hemisphere on the mold plate. The direction adjustment machine is composed of a transmission device and a direction adjustment gate. The direction adjustment gate includes a direction adjustment gate horizontally mounted on the transmission device. A frame and a plurality of cylindrical baffles installed on the horizontal frame of the adjustment gate; one cylindrical baffle corresponds to a row of hemispheres and is located on the same side of the corresponding row of hemispheres. As the mold plate passes through the adjustment gate, a row of hemispheres passes through the corresponding cylindrical baffles in turn, and a plug column on the hemisphere touches the corresponding cylindrical baffle, and under the restriction of the corresponding cylindrical baffle, the hemisphere rotates around the central column until the plug column can just bypass the corresponding cylindrical baffle, and the hemisphere passes through the corresponding cylindrical baffle, thereby realizing the adjustment of the hemispheres on the same mold plate.
