Description

Technical Field

[0001] This utility model relates to the field of toy assembly technology, and in particular to a connector for toy assembly. Background Technology

[0002] Due to the needs of toy packaging and the enjoyment of assembly, the parts are usually disassembled and placed separately, and then reassembled during toy assembly. Connectors are often used to serve as transitions and connections, especially in the connection between columns to extend the structure or complete the toy's shape.

[0003] Chinese Patent Authorization Announcement No.: CN 218218749 U, Authorization Announcement Date: January 6, 2023. This utility model relates to a multifunctional cat climbing frame, aiming to provide a multifunctional cat climbing frame that enhances fun. It includes a frame, from bottom to top, a cat house, a cat basket, and a top plate. The side wall of the cat house has an opening. A middle plate and a cat basket are connected to the frame, both located on the side of the cat house. The middle plate is located at the opening of the cat house, and the cat basket is located between the cat basket and the middle plate. A ladder is provided on the middle plate, which is arranged at an angle and connected to the edge of the middle plate. The drawback of this technical solution is that it is difficult to ensure the stability of the connection between the various connecting columns, which makes the toy climbing frame prone to collapse or deformation.

[0004] In summary, toy assembly suffers from the inability to guarantee connection stability, leading to the overall structure being prone to collapse and deformation. Utility Model Content

[0005] This invention aims to overcome the shortcomings of existing toy assembly technologies, which suffer from difficulties in ensuring connection stability, leading to easy collapse and deformation of the whole assembly. It provides a toy assembly connector that improves connection stability and prevents collapse and deformation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A connector for assembling a toy, including

[0008] The column body has an internal cavity designed as an installation cavity.

[0009] The connector is inserted into the mounting cavity, and one end of the connector has a chamfered structure.

[0010] The limiting strip is connected to the column body, and the outer side of the connecting seat is provided with a limiting groove, and the limiting strip is inserted into the limiting groove;

[0011] The mounting cavity is a variable diameter cavity structure. The inner diameter of the cavity opening is larger than the inner diameter of the cavity and is set as a stepped hole. The limiting strip is connected to the inner wall of the stepped hole.

[0012] The buckle connects to the limiting groove, and the limiting strip has a slot, with the buckle engaging with the slot.

[0013] The mating hole is the inner hole of the connector, and the hole wall of the mating hole is provided with internal threads;

[0014] Gravity support component, which is connected to the mounting cavity, and the connecting seat abuts against the gravity support component.

[0015] The column has a cylindrical structure with an inner cavity designed as a mounting cavity. The chamfered structure of the connector causes one side of the port to taper inward. The outer diameter of the chamfered port of the connector is smaller than the diameter of the stepped hole in the mounting cavity, allowing the connector to be quickly and smoothly inserted into the column. The inner cavity of the mounting cavity is a variable-diameter cavity structure, making the inner diameter of the stepped hole on the side of the mounting cavity connected to the connector larger. This creates a stepped shape between the stepped hole and the rest of the mounting cavity, facilitating the placement of the positioning limit strip and limiting the portion outside the chamfered structure. Several positioning strips and positioning grooves are provided. The components are arranged in a uniform circumferential pattern to improve connection strength. A limiting groove prevents the limiting strip (connecting seat) from rotating horizontally, and a snap-fit ​​mechanism prevents radial movement of the connecting seat. This allows for quick and secure fastening when connected to another column's connecting seat, ensuring docking stability. The connecting seat has a docking hole at its central axis for connecting to a threaded screw with an external thread via an internal thread. The connecting seats between two columns are assembled using a double-ended screw, extending the connection between toy parts. A gravity support component limits the connection between the connecting seat and the column after assembly, enhancing the column's ability to withstand radial gravity. This achieves improved connection smoothness and efficiency during assembly, high connection strength, high locking stability, and strong radial load-bearing capacity after assembly, preventing toy structural deformation and collapse.

[0016] Preferably, the stepped hole has a feed chamfer at one end, with the chamfer's surface engaging with the inner wall of the stepped hole. A limiting stop is connected to the other end of the connector, fitting snugly against the feed chamfer. The feed chamfer on one side of the stepped hole causes the end face of the column to tilt inwards and contract, further improving the smoothness of the connector entering the stepped hole. Simultaneously, after the connector enters, the limiting stop engages with the feed chamfer, further limiting the connector's entry position and preventing over-insertion. This achieves the effect of improving the connection compatibility, smoothness, and load-bearing capacity between the connector and the column.

[0017] Preferably, the end face of the limiting strip is provided with a second feeding chamfer, the surface of which connects with the surface of the first feeding chamfer. The beveled surface of the first feeding chamfer connects with the beveled surface of the second feeding chamfer, allowing for a smooth transition to the connecting seat and preventing the buckle from getting stuck at the end of the limiting strip. This further improves the smoothness of the assembly of the connecting parts.

[0018] Preferably, the slot opening is provided with a third infeed chamfer, which is located on the side of the slot near the second infeed chamfer. The third infeed chamfer is provided on the slot wall on the side near the second infeed chamfer, allowing the buckle to enter the slot along the third infeed chamfer, thus reducing jamming and hard impacts that could cause structural damage during interference fit. This improves the smoothness of buckle assembly and protects the components.

[0019] Preferably, the buckle has a right-angled trapezoidal cross-section, with the inclined surface facing the limiting strip. This trapezoidal cross-section allows the buckle to quickly enter the slot via the first and second feed chamfers, and the two sides of the right-angled surface abut against the inner wall and bottom of the right-angled slot below the third feed chamfer. This further improves the smoothness and stability of the buckle assembly.

[0020] Preferably, the gravity support includes a fixed seat and a support ring. The fixed seat is connected to the inner wall of the mounting cavity. One side of the support ring has a limiting groove, into which the fixed seat engages. The connecting seat abuts against the other side of the support ring. The fixed seat is fixedly connected to the inner wall of the mounting cavity to position the support ring. After entering the mounting cavity, the support ring is embedded into the fixed seat through the limiting groove, thus securing the connecting seat and preventing excessive radial gravity from causing the latch and limiting edge to fail. This enhances the load-bearing strength of the connecting seat.

[0021] Preferably, the gravity support includes a positioning ring, which is connected to the support ring and plugs into the port of the connecting seat. The positioning ring is attached to the support ring to facilitate interlocking with the port at the chamfered structure after the connecting seat is inserted. This further ensures the contact accuracy and tightness between the connecting seat and the support ring.

[0022] Preferably, the end face of the column is provided with a protective chamfer, the chamfer surface of which connects with the outer surface of the column. The protective chamfer is the beveled outer edge of the end face of the column, so that when the connecting seat is forcefully inserted into the column, the inclined chamfer prevents scratches to operators in case of misalignment. This achieves the effect of improving operational safety during structural assembly.

[0023] The beneficial effects of this utility model are: improving the smoothness and efficiency of connection between connectors during assembly; high connection strength and high locking stability; strong radial load-bearing capacity after assembly to prevent toy structure deformation and collapse; improving the connection matching degree, smoothness and load-bearing capacity between structures; protecting accessories; enhancing the structural stress strength; and improving operational safety.
