As shown in fig. 1-19, the preferred embodiment of the present application is:

the utility model provides a building blocks toy, includes structure 1 and connecting piece 2, has seted up at least one joint groove 11 on the structure 1, is provided with at least one joint piece 21 on the connecting piece 2, and joint piece 21 is suitable for along axial business turn over joint groove 11, and joint groove 11 and joint piece 21 are suitable for along radial spacing to make structure 1 splice with connecting piece 2. The axial direction in the above structure is along the axial direction of the limit section 211 at the top end of the connecting piece 2, i.e. the transverse front-back direction in fig. 1; the radial direction is a radial direction along the stopper section 211, i.e., a longitudinal direction and a lateral left-right direction in fig. 1.

At present, the building blocks toy in the market can only be the shaping for the fixed object that sets up in advance mostly, for example, the car, dinosaur etc. because they are most all with connecting piece 2 and structure 1 integrated into one piece, make the concatenation mode not flexible enough, the operator is difficult to splice according to the thought of oneself wantonly when the concatenation, hardly form except that predetermine the external reasonable of object and pleasing to the eye object, therefore, the inventor of this application sets up structure 1 and 2 components of a whole that can function independently of connecting piece, and arbitrary structure 1 all can splice through connecting piece 2, thereby make client can splice structure 1 according to the thought of oneself wantonly, and can the rational shaping, the playability of the building blocks toy of this application has been improved to a certain extent.

As shown in fig. 1, in the present embodiment, the clamping groove 11 is opened along the radial direction, the clamping groove 11 includes a limiting cavity 111 and an extending cavity 112, the clamping block 21 includes a limiting section 211 and an extending section 212, when the clamping block 21 is disposed in the clamping groove 11, the limiting section 211 and the limiting cavity 111 are matched to realize radial limiting, and the extending section 212 is adapted to pass through the extending cavity 112 and reach or exceed the side surface of the structural member 1. The structure is used for connecting the clamping block 21 and the clamping groove 11, and has the advantages of simple and stable structure.

Further, in order to realize the radial spacing of the matching of the spacing section 211 and the spacing cavity 111, in this embodiment, the cross sections of the spacing section 211 and the spacing cavity 111 are in adaptive major arc fan-shaped structures. The sector major arc that this sectorial arc is greater than the semicircle, the advantage of above-mentioned structure lies in, the sector structure of major arc is greater than the semicircle, consequently, extend the width that chamber 112 can be less than spacing chamber 111, make spacing section 211 place when spacing chamber 111 is interior, spacing section 211 is close to the one side that extends section 212 also offsets with spacing intracavity 111 inner wall, thereby make when spacing section 211 inserts spacing chamber 111 back from axial direction, can' T follow radial direction position and shift out spacing chamber 111, it is worth mentioning that, spacing section 211 and spacing chamber 111 can also choose for use the T type structure of adaptation, also can play the same effect, however, compare in T type structure, the surface of the sector structure of major arc is the circular arc, make the atress more even, can effectively increase the life of spacing section 211.

Further, for the stability that improves joint piece 21 and joint groove 11 and connect, in this embodiment, be provided with first reinforcement 2111 and first recess 2112 on the spacing section 211, first reinforcement 2111 rotationally locates first recess 2112 edge and first reinforcement 2111 is suitable for the first recess 2112 of anteversion rotation business turn over, be equipped with first arch 2113 that steps up on first reinforcement 2111, and when joint piece 21 got into in the joint groove 11, first arch 2113 that steps up was suitable for and offsets with joint groove 11 inner wall. First arch 2113 of tightening can play like interference fit's effect, increase the frictional force between joint piece 21 and the joint groove 11, thereby improve the stability that both connect, furthermore, it is in order to improve stability to set up first recess 2112, the simplicity of connection has been guaranteed reliably, when joint piece 21 inserts in the joint groove 11, first reinforcement 2111 can receive pressure and to first recess 2112 internal rotation certain angle, make things convenient for joint piece 21 to get into joint groove 11, play automatically regulated's effect promptly.

In addition, for the flexibility that improves joint groove 11 and joint piece 21 and connect, in this embodiment, joint groove 11 all is equipped with the opening on two lateral walls of structure 1 along the axial, and through two openings, joint piece 21 all is suitable for business turn over joint groove 11. Above-mentioned structure has guaranteed the flexibility that joint piece 21 and joint groove 11 are connected reliably, and joint piece 21 can be followed the arbitrary one end business turn over joint groove 11 of joint groove 11 to prevent when the other end of joint groove 11 is sheltered from by other structure 1 or external environment, can consequently influence the normal concatenation of structure 1.

Furthermore, as shown in fig. 2-4, in the present embodiment, two clamping blocks 21 are disposed on the connecting member 2, the extending sections 212 of the two clamping blocks 21 are connected to each other, and the extending sections 212 are adapted to the extending cavity 112 in radial length, and the two structural members 1 are adapted to be connected by the connecting member 2 having the two clamping blocks 21. Connecting piece 2 in the above-mentioned structure is by two joint piece 21 integrated into one piece of mutual inversion to set up the radial length of extension 212, when making two joint piece 21 combinations back and both ends respectively with a structure 1 joint, the lateral surface of two structures 1 touches mutually, thereby makes the building blocks after the concatenation inseparabler, more abundant utilization space.

It should be noted that, as shown in fig. 14, in this embodiment, the connecting member 2 provided with the two clamping blocks 21 is also divided into types with different axial lengths, so as to adapt to the structural members 1 with different thicknesses, or the connecting member 2 with an axial length larger than the thickness of the structural member 1 may be adopted during splicing, and then the connecting member 2 axially penetrates through the structural members 1, thereby achieving the purpose of axial splicing.

In addition, as shown in fig. 5, in the present embodiment, the block toy further includes a rod 4, at least one connecting hole 12 is provided on the structural member 1, the rod 4 is adapted to enter and exit the connecting hole 12 along an axial direction of the connecting hole 12, and the rod 4 and the connecting hole 12 are adapted to cooperate to achieve radial position limitation. The structure is used for increasing the selection of the splicing mode of the structural part 1, so that an operator can select the simplest splicing mode according to actual conditions during splicing, and the splicing flexibility is further increased, for example, when the operator wants to splice two structural parts 1 axially, at the moment, the selection of the rod part 4 is simpler and more convenient, and the rod part 4 can also be used as an auxiliary fixing part.

In order to improve the stability of the connection between the rod member 4 and the connection hole 12, in some structural members 1 of the present embodiment, a plurality of protruding ribs 13 are uniformly arranged along the circumferential direction on the inner wall of the connection hole 12, and the rod member 4 is adapted to abut against the protruding ribs 13 when inserted into the connection hole 12. The structure is simple and the reinforcing effect is excellent.
