Description

Technical Field

[0001] The utility model belongs to the technical field of amusement facilities, and in particular relates to a children's easy-to-assemble and versatile game frame. Background Art

[0002] A children's play frame is a facility that provides entertainment and development training for children, and is generally composed of a track component and a platform.

[0003] The existing children's play frame track modules are usually connected by screws. The disadvantage is that the screws are easily corroded and loosened due to wind and sun after long-term use, which can easily cause safety hazards. In addition, the screw connection forms a fixed assembly between the track modules, and the track modules cannot be assembled and combined at any time during play, which reduces the game changes and the fun of playing. Utility Model Content

[0004] The utility model aims to solve the problems in the prior art and provides a children's easy-to-assemble and versatile play frame which has no screw connections and can be assembled and combined at will.

[0005] The technical solution of the utility model includes a track module, a track connection module and a circular ring base. Two columns are respectively arranged at both ends of the track module. The columns are cylinders. The upper and lower end surfaces of the columns are both hemispherical. The track connection module is a hollow hemisphere. An annular groove is provided on the outer circular surface of the hemisphere of the track connection module. The center of the annular groove is on a virtual radius perpendicular to the virtual bottom surface of the hemisphere. The bottom surface of the annular groove has an arc adapted to the upper and lower ends of the columns. The two ends of the track module are concave arc end surfaces. The arc end surfaces have the same virtual center as the annular groove. The columns are symmetrically arranged at both ends of the arc end surfaces. The bottom of the track connection module is provided with square convex teeth and square grooves along the inner wall of the sphere. The square convex teeth and square grooves are interspersed and arranged at intervals around the inner wall of the sphere. The upper end surface of the circular ring base has an annular boss adapted to the annular groove.

[0006] Preferably, a cavity is provided inside the lower end of each column of the track module, and a counterweight ball is provided in the cavity.

[0007] Preferably, the track module includes a curved track and a straight track.

[0008] The beneficial effects of the present invention are as follows: the track module and the track connection module are assembled by snapping together the columns and the annular slots, replacing the screw connections, making the amusement equipment safer, and because the arc-shaped end face has the same virtual center as the annular slot, the track module can be snapped together 360 degrees around the annular slot, which makes assembly simple and enhances the variability of the shape and the fun of playing; a counterweight ball is arranged in the internal cavity of the column to improve the stability of the device.

[0015] like Figure 1-3 The illustrated embodiment of a children's easy-to-assemble and versatile play frame comprises a track module 1, a track connection module 2, and a circular base 3. Two columns 5 are provided at each end of the track module 1. The columns 5 are cylindrical, and the upper and lower end surfaces of the columns 5 are both hemispherical. The track connection module 2 is a hollow hemispherical body. An annular groove 4 is provided on the outer circumference of the hemispherical surface of the track connection module 2. The center of the annular groove 4 is on a virtual radius perpendicular to the virtual bottom surface of the hemispherical body. The bottom surface of the annular groove 4 has a curvature that matches the upper and lower ends of the columns 5. Figure 4 As shown, both ends of the track module 1 are concave arcuate end surfaces 8, and the arcuate end surface 8 has the same virtual center as the annular slot 4. The columns 5 are symmetrically arranged at both ends of the arcuate end surface 8. When in use, the two columns 5 of the arcuate end surface 8 are snapped into the annular slot 4 to complete the assembly of the track module 1 and the track connection module 2. Different track modules 1 can be snapped into different track connection modules 2. Since the arcuate end surface 8 has the same virtual center as the annular slot 4, the track module 1 can be snapped into any 360-degree connection around the annular slot 4, which enhances the fun of assembly and play. Figure 5As shown, the bottom of the track connection module 2 is provided with square protrusions 6 and square grooves 7 along the inner wall of the sphere, and the square protrusions 6 and square grooves 7 are interspersed at intervals around the inner wall of the sphere. When in use, the bottom of the track connection module 2 can be placed directly on the ground as a base, or the square protrusions 6 and square grooves 7 of two track connection modules 2 can be connected to each other to form a sphere, so that the height and shape of the track connection module 2 are variable; the upper end face of the circular base 3 has an annular boss adapted to the annular groove 4, and the annular boss of the circular base 3 is inserted into the annular groove 4 of the inverted track connection module 2 to improve the stability of the track connection module 2.

[0016] The lower ends of the columns 5 of the track module 1 are each provided with a cavity, in which a counterweight ball is provided. When the column 5 is inserted into the annular slot 4 or placed on the ground, the counterweight ball can improve the stability of the track module 1 .

[0017] The track module 1 includes a curved track and a straight track.
