Toy plug-in structure

Abstract

A toy plug-in structure includes a basic connecting unit. The front end of the basic connecting unit has a plug-in post, and the rear end of the basic connecting unit has a plug-in hole that matches the plug-in post. The plug-in post is cylindrical or frustum-shaped. At least one inwardly recessed positioning groove is provided on the side wall of the plug-in post. The two side walls of the positioning groove each have a first inclined surface that gradually slopes inward from the end to the middle. At least one outwardly protruding positioning block is provided on the side wall of the plug-in hole. The positioning block corresponds one-to-one with the positioning groove. The inner wall surface of the positioning block gradually slopes inward from back to front. The two side walls of the positioning block each have a second inclined surface that gradually slopes inward from the end to the middle, and the second inclined surface corresponds to the first inclined surface in position, forming a continuous sliding surface. This toy plug-in structure facilitates connection and disassembly, and disassembly does not require forceful pulling, preventing damage to the plug-in parts and effectively extending the toy's lifespan.

Claims

1. A toy plug-in structure, comprising: a basic connecting unit, a plug-in post at the front end of the basic connecting unit, and a plug-in hole at the rear end of the basic connecting unit that matches the plug-in post, characterized in that: the plug-in post is cylindrical or frustum-shaped; at least one inwardly recessed positioning groove is provided on the side wall of the plug-in post, and the two side walls of the positioning groove are respectively provided with a first inclined surface that gradually slopes inward from the end to the middle; at least one outwardly protruding positioning block is provided on the side wall of the plug-in hole, the number of positioning blocks is the same as the number of positioning grooves and they correspond one-to-one, the inner wall surface of the positioning block gradually slopes inward from the back to the front, and the two side walls of the positioning block are respectively provided with a second inclined surface that gradually slopes inward from the end to the middle, and the second inclined surface corresponds to the position of the first inclined surface, and the second inclined surface and the first inclined surface form a continuous sliding surface.

2. The toy plug-in structure as described in claim 1, wherein, The inclination angles of the first and second inclined planes are 20° to 35°.

3. The toy plug-in structure as described in claim 1, wherein, The front end of the side wall of the plug is provided with at least one third inclined surface that gradually slopes inward from back to front, and the front end of the inner side wall of the plug hole is provided with at least one fourth inclined surface that gradually slopes inward from back to front. The number of third and fourth inclined surfaces is the same and they correspond one-to-one.

4. The toy plug-in structure as described in claim 3, wherein, The number of positioning grooves and positioning blocks is multiple, and the number of third and fourth inclined surfaces is multiple. Each positioning groove and each third inclined surface is evenly arranged along the circumference of the plug post, and the third inclined surface is located between two adjacent positioning grooves. Each positioning block and each fourth inclined surface is evenly arranged along the circumference of the plug hole, and the fourth inclined surface is located between two adjacent positioning blocks.

5. The toy plug-in structure as described in claim 1, wherein, The rear end of the side wall of the plug is provided with at least one outwardly protruding positioning step, and the front end face of the positioning step gradually slopes forward from both sides towards the middle; the rear wall of the plug hole is provided with at least one step notch, and the number of step notches is the same as that of the positioning steps and they correspond one-to-one.

6. The toy plug-in structure as described in claim 5, wherein, The number of positioning grooves and positioning blocks is multiple, and the number of positioning steps and step notches is multiple. Each positioning groove and each positioning step is evenly arranged along the circumference of the plug post, and the positioning step is located between two adjacent positioning grooves; each positioning block and each step notch is evenly arranged along the circumference of the plug hole, and the step notch is located between two adjacent positioning blocks.

7. The toy plug-in structure as described in claim 1, wherein, The rear end of the side wall of the plug is provided with at least one outwardly protruding first protrusion, which is located behind the positioning groove; the rear wall surface of the plug hole is provided with at least one protrusion positioning port, which is the same number as the positioning block and corresponds one-to-one. The protrusion positioning port is located behind the corresponding positioning block, and the position of the protrusion positioning port corresponds to that of the first protrusion.

8. The toy plug-in structure as described in claim 7, wherein, At least one set of protruding posts is provided on the rear wall of the insertion hole. The set of protruding posts includes two second protruding posts, which are arranged side by side, and the space between the two second protruding posts forms the protruding post positioning port.

9. The toy plug-in structure as described in claim 8, wherein, The longitudinal sections of both the first and second protruding pillars are semi-circular.
