Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

A composite toy connector comprising: a central piece 1. The center 1 is provided with a through opening 11, and the through opening 11 may be a groove shape having one end opened and the other end closed, or a hole shape penetrating the center 1. The inner wall of the through opening 11 is provided with a plurality of friction protrusions 111, and the cross section of the through opening 11 is circular or polygonal so as to adapt to tubular connecting pieces in various shapes.

During the in-service use, can pass through opening 11 with the tubular connecting piece and insert in the centerpiece 1 for the outer wall of tubular connecting piece only meets department with friction arch 111, thereby reduces the area of contact between tubular connecting piece and the 11 inner walls of opening through friction arch 111, and then reduces the frictional force between tubular connecting piece and the 11 inner walls of opening, even make tubular connecting piece or centerpiece 1 age or slightly deform, still can comparatively easy the insertion or extract between tubular connecting piece and the centerpiece 1.

Wherein, the protruding 111 quantity of friction is a plurality of, the even setting of the protruding 111 of friction is on the inner wall of opening 11, when making the tubulose connecting piece insert the centre part 1, the protruding 111 of friction can be even encircle around the tubulose connecting piece, thereby make the protruding 111 of friction can play limiting displacement to the tubulose connecting piece, can avoid being connected inadequately between tubulose connecting piece and the centre part 1 on the one hand, cause the tubulose connecting piece to rock in the 1 inside of centre part, on the other hand can make the tubulose connecting piece insert behind the centre part 1, the axis of tubulose connecting piece can coincide mutually with the axis of centre part 1, thereby improve the combination degree of toy.

Wherein, the protruding 111 of friction is the strip, the protruding 111 of friction is on a parallel with the axis setting of centre part 1, make the protruding 111 shape of friction and arrange comparatively regularly, thereby make in-process at the production design, be convenient for regulate and control the frictional force between tubular connection spare and the centre part 1, thereby make frictional force can not the undersize, lead to the tubular connection spare can be easily slide in the centre part 1, also make frictional force can not too big, lead to the insertion or the extraction inconvenience of tubular connection spare.

Meanwhile, chamfers are arranged at two ends of the friction bulge 111, so that if the tubular connecting piece is abutted to one end of the friction bulge 111 in the process of being inserted into the central connecting piece 1, the chamfer angle on the friction bulge 111 can effectively correct the insertion angle of the friction bulge 111, and the tubular connecting piece is effectively prevented from being clamped with the friction bulge 111 due to the inclination of the insertion angle.

The connector also comprises a connecting part, wherein the connecting part comprises one or two of a plug-in part 21 and a butt joint part 22. When the two types of the connecting parts are included, the inserting part 21 is arranged on one side of the central piece 1, the axis of the inserting part 21 is perpendicular to the axis of the central piece 1, and the inserting part 21 is fixedly connected with the central piece 1. The inserting part 21 is columnar, and one end of the inserting part 21 far away from the central part 1 is provided with a clamping groove 211. The abutting part 22 is arranged on one side of the central piece 1 opposite to the inserting part 21, the axis of the abutting part 22 is perpendicular to the axis of the central piece 1, the abutting part 22 is fixedly connected with the central piece 1, the abutting part 22 is provided with an abutting interface 221 corresponding to the inserting part 21, and the inner wall of the abutting interface 221 is provided with a clamping protrusion 2211 corresponding to the clamping groove 221.

When two central connecting pieces 1 need to be connected, one end of the inserting part 21 provided with the clamping groove 211 is aligned to the butt joint port 221 of the butt joint part 22, and the central piece 1 is pushed, so that the inserting part 21 extends into the butt joint part 22 through the butt joint port 221 until the inserting part 21 is abutted to the clamping protrusion 2211. Continue to promote centre piece 1, impel grafting portion 21 and butt joint portion 22 to take place deformation jointly to make grafting portion 21 can continue to stretch into butt joint portion 22 through joint arch 2211, and then make joint arch 2211 imbed in joint groove 211. At this time, the insertion of the insertion part 21 into the docking port 221 is completed, thereby completing the connection of the two center connection members 1.

Wherein, the end of the inserting part 21 far away from the central part 1 is further provided with a deformation groove 212, and one side of the deformation groove 212 with the inserting part 21 penetrates to the other side. By using the deformation groove 212, when the inserting-connecting part 21 is deformed, the parts at the two sides of the deformation groove 212 are converged to the direction of the deformation groove 212 together, thereby completing the deformation. From this, when can making grafting portion 21 and butt joint portion 22 peg graft, grafting portion 21 deforms more easily to reduced and impeld grafting portion 21 to carry out the required power of deformation, and then further be convenient for the child to assemble.

It should be noted that the number of the connecting portions is one or more, and in practical production, it may be in a form of only providing one inserting portion 21 as shown in fig. 1, or in a form of only providing one abutting portion 22 as shown in fig. 2, or in a form of providing two inserting portions 21 as shown in fig. 3, or in a form of providing two abutting portions 22 as shown in fig. 4, and so on, so that the present invention can connect the center piece and other parts of the combined toy in addition to the two center pieces 1.

The present invention can take various forms, not limited to the four forms described above, which are only for illustrative purposes.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
