In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

Referring to fig. 1 to fig. 3, a twist-embedded building block structure 100 according to a preferred embodiment of the present invention mainly includes at least one extension bar 10 and a connector unit 20, wherein:

referring to fig. 1 to 3, the extension rod 10 is integrally made of a plastic material with a slight elastic deformation capability. The extension rod 10 has a holding portion 11 and at least one coupling protrusion 12 axially protruding from one end of the holding portion 11, the coupling protrusion 12 is tapered, the outer diameter gradually expands from the outer end to the inner end of the coupling protrusion 12, and the maximum outer diameter of the coupling protrusion 12 is smaller than the outer diameter of the holding portion 11. At least one protruding grain ring 121 is formed on the outer peripheral surface of the combining convex part 12, the protruding grain ring 121 has a plurality of protruding grains 122 arranged intermittently in a ring shape, and the protruding grain ring 121 is located on the outer peripheral surface close to the outer end of the combining convex part 12. The extension rod 10 has a packing ring 13 between the holding portion 11 and the combining protrusion 12, that is, the packing ring 13 is located at the inner end of the combining protrusion 12, the outer diameter of the outer end of the packing ring 13 is slightly larger than the outer diameter of the inner end of the packing ring 13, and the maximum outer diameter of the packing ring 13 is smaller than the outer diameter of the holding portion 11 and larger than the maximum outer diameter of the combining protrusion 12.

Referring to fig. 1 to 3, the connector unit 20 has at least one connector 21, and the connector 21 is integrally made of a plastic material with a slight elastic deformation capability. The joint 21 has a holding portion 211 and at least one engaging recess 212 axially recessed from one end of the holding portion 211, the engaging recess 212 is tapered, and the inner diameter of the engaging recess 212 is gradually reduced from the outer end to the inner end. The inner peripheral surface of the combining concave part 212 is formed with at least one groove ring 213, and the groove ring 213 is located on the inner peripheral surface close to the inner end of the combining concave part 212, the groove ring 213 has a plurality of grooves 214 arranged intermittently in a ring shape, the grooves 214 extend along the inner peripheral surface of the combining concave part 212 in a radial direction and are in a long strip shape, the middle position of the grooves 214 is a deep groove region 215, the two ends are respectively a shallow groove region 216, the groove depth of the grooves 214 gradually decreases from the deep groove region 215 to the shallow groove region 216, and the grooves 214 are in a meniscus shape, that is, the two ends of the grooves 214 gradually bend towards the outer end of the combining concave part 212. The outer end of the combining concave part 212 is formed with a packing groove 217, and the inner diameter of the packing groove 217 is slightly smaller than the outer diameter of the outer end of the packing ring 13 of the extension rod 10 and equal to the outer diameter of the inner end of the packing ring 13.

Therefore, the above description is a description of each component of the twist-in type building block structure 100 provided in a preferred embodiment of the present invention, and then the using characteristics thereof are described as follows:

first, referring to fig. 3 to 8, when an extension rod 10 is to be connected to a connector 21, the connection protrusion 12 of the extension rod 10 is moved toward the connection recess 212 of the connector 21 (as shown in fig. 4), so that the connection protrusion 12 is inserted into the connection recess 212, and the protrusions 122 of the extension rod 10 are located in the deep groove regions 215 of the grooves 214 of the connector 21 (as shown in fig. 3 and 5), thereby achieving the purpose of connecting the extension rod 10 and the connector 21. Meanwhile, when the coupling protrusion 12 is inserted into the coupling recess 212, the packing ring 13 of the extension rod 10 is slightly deformed and forced into the packing groove 217 of the joint 21 (as shown in fig. 3) to increase the strength after coupling.

Then, when the connecting rod 10 and the joint 21 are to be detached from each other, either the connecting rod 10 or the joint 21 can be rotated to rotate in either a forward rotation or a reverse rotation (as shown in fig. 6 and 7), so that each protrusion 122 of the connecting rod 10 is rotated to move from the deep groove area 215 of each corresponding groove 214 of the joint 21 to the shallow groove area 216, and each protrusion 122 can be subjected to a slope action between the deep groove area 215 and the shallow groove area 216 to smoothly and gently slide out of the groove 214, so that the connecting rod 10 can be detached from the joint 21 (as shown in fig. 8). Moreover, since the two ends of the groove 214 are gradually curved toward the outer end of the concave connection portion 212 to form a crescent shape, when the protrusion 122 of the connecting rod 10 moves from the deep groove 215 to the shallow groove 216, the connecting rod 10 is also axially separated from the joint 21 by the crescent shape of the groove 214, so that the detachment is smoother, smoother and more labor-saving.

In addition, although in the above embodiment, the bead ring 121 of the extension rod 10 is located on the outer circumferential surface close to the outer end of the coupling protrusion 12; and the groove ring 213 of the nipple 21 is located on the inner circumferential surface close to the inner end of the coupling recess 212. However, in practice, as shown in fig. 9, the bead ring 121 of the extension rod 10 may be located on the outer circumferential surface near the inner end of the coupling protrusion 12; the groove ring 213 of the connector 21 can be located on the inner peripheral surface close to the outer end of the combining recess 212, which can achieve the same effect.

Furthermore, although the above embodiment shows the extension rod 10 having a knob ring 121; the connector 21 has a groove ring 213. However, in practice, as shown in fig. 10, the extension rod 10 may also have two convex particle rings 121; the connector 21 has two groove rings 213, which can achieve the same effect.

Furthermore, although in the above embodiments, the extension rod 10 has a knob ring 121; the connector 21 has a groove ring 213. However, in practice, as shown in fig. 11, the extension rod 10 may also have two or more convex particle rings 121; the connector 21 has two or more groove rings 213, and the convex particles 122 on the adjacent convex particle rings 121 are disposed in a staggered manner, and the grooves 214 on the adjacent groove rings 213 are disposed in a staggered manner, which can achieve the same effect.

Although in the above embodiments, the extension bar 10 is a stub bar. However, in practice, extension bar 10 can also be a long axis extension bar 10 (as shown in FIG. 12).

In the above embodiment, as shown in fig. 13, the extension rod 10 is a short shaft extension rod, and the outer peripheral surface of the grip 11 is provided with a slip-resistant texture 14, so that when the extension rod is used as a wheel shaft, the friction force during rotation can be increased.
