The two connecting balls can be connected by a connecting rod, and children can climb, walk, and jump on the sensory integration training connecting ball to exercise their sensory integration ability.

[0004] However, the training frame formed by assembling only the connecting balls (connecting the individual connecting balls in the horizontal direction through the connecting rods) is not very effective and cannot meet the needs of all customers (for example, the climbing height and climbing difficulty are not enough). The existing connecting ball structure cannot be directly connected in an overlapping manner, nor can it be assembled and connected with the connecting plate. Therefore, it cannot be used as a connecting column of the balance obstacle game frame. Summary of the invention

[0070] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0071] like Figures 1 to 4 As shown, an obstacle climbing connecting column includes a column body 1, a column cover 2, and a connecting piece connecting the column body 1 with the column cover 2 or another column 1 above. The column 1, the column cover 2 and the connecting piece are assembled to form a connecting column of any height; the column 1 is connected with the column cover 2 or another column 1 to form a connecting groove; two adjacent connecting columns are connected by a connecting plate assembled and connected to the connecting groove.

[0072] The present application can stack any number of columns 1 or column covers 2 together through the setting of connecting pieces to form a connecting column structure of any height for children to climb. The columns can be connected by connecting plates through the setting of connecting grooves, thereby meeting the assembly requirements of various balance obstacle game frames. Users can assemble balance obstacle game frames of the required training difficulty according to actual usage requirements. Therefore, the application is extremely wide in applicability, and the assembled connecting column structure is very stable, has high safety performance, and is very easy to assemble and disassemble, providing a good user experience.

[0073] like Figure 5 and Figure 6 As shown, the first embodiment of the connector of the present application comprises a support body 3-1, a support plate 3-2, a clamping joint 3-3, a clamping rod 3-4, a rotating body 3-5, a rotating shaft 3-6 and a rotating screw 3-7. The support body 3-1 is connected to the column 1, the two support plates 3-2 are symmetrically arranged on the front side of the support body 3-1, the clamping rod 3-4 is vertically arranged, and its top end is connected to the clamping joint 3-3, the rotating body 3-5 is vertically provided with an opening allowing the other end of the clamping rod 3-4 to enter from its top, the rotating shaft 3-6 connects the rotating body 3-5 and the other end of the clamping rod 3-4, and the rotating screw 3-7 connects the support plate 3-2 and the rotating body 3-5. The column 1 is provided with a receiving groove for installing the connecting piece, the column cover 2 is provided with a column cover slot 3-2-1 that is docked with the receiving groove and assembled with the connecting piece of the column 1, and the column 1 is provided with a column slot 3-1-1 at the bottom of the receiving groove that is assembled with another connecting piece of the column 1.

[0074] When the column cover 2 needs to be connected to the column body 1, it is only necessary to place the column cover 2 on the top of the column body 1, and then rotate the rotating body 3-5 in a horizontal state to a vertical state along the rotating screw 3-7. During the rotation, the rotating body 3-5 will drive the clamping joint 3-3 to enter the column cover clamping slot 2-1 through the clamping rod 3-4 (during the rotation of the rotating body 3-5, the clamping rod 3-4 is always in a vertical state, and the rotating body 3-5 will rotate relative to the clamping rod 3-4 through the rotating shaft 3-6, thereby driving the clamping rod 3-4 to move its position). At this time, the connecting piece connects and fixes the column cover 2 to the column body 1. When it is necessary to detach the column cover 2 from the column body 1, it is only necessary to rotate the rotating body 3-5 in the vertical state to the horizontal state along the rotating screw 3-7. During the rotation, the rotating body 3-5 will drive the clamping joint 3-3 to leave the column cover slot 2-1 through the clamping rod 3-4 (during the rotation of the rotating body 3-5, the clamping rod 3-4 is always in the vertical state, and the rotating body 3-5 will rotate relative to the clamping rod 3-4 through the rotating shaft 3-6, thereby driving the clamping rod 3-4 to move position). At this time, the column cover 2 and the column body 1 can be directly separated. The connecting piece of this structure can quickly disassemble and assemble the column body 1 and the column cover 2. After assembly, the structure is very stable and has high safety performance. The disassembly and assembly process of the column 1 and the column 1 is the same.

[0075] like Figures 7 to 11 As shown, the second embodiment of the connector of the present application, the connector includes a locking rod 7-1, a nut 7-2 and a cam wrench 7-3. The axial top end of the locking rod 7-1 is provided with a threaded connection end, and the axial bottom end is provided with a radial through hole. The nut 7-2 is detachably connected to the threaded connection end. The cam wrench 7-3 is provided with an axial mounting portion that is rotatably connected to the radial through hole through a wrench shaft, and an arc-shaped opening groove that allows the axial bottom end of the locking rod 7-1 to enter and allows the locking rod 7-1 to rotate around the axial mounting portion. The axial mounting portion is eccentrically arranged so that the length of the locking rod 7-1 located inside the arc-shaped opening groove is different at different rotation angles of the cam wrench 7-3. The bottom of the column 1 is provided with a wrench accommodating groove 7-1-1 for accommodating the cam wrench 7-3, and a locking rod mounting hole 7-1-2 that vertically penetrates the column 1 from the wrench accommodating groove 7-1-1. The column cover 2 is provided with a locking rod docking hole 7-2-1 for allowing the axial top end of the locking rod 7-1 to pass through, and a nut receiving groove 7-2-2 for receiving the nut 7-2.

[0076] When it is necessary to connect the column cover 2 to the column body 1, it is only necessary to place the column cover 2 on the top of the column body 1, and then insert the axial top end of the locking rod 7-1 into the locking rod mounting hole 7-1-2 in the wrench receiving groove 7-1-1 and pass it through the locking rod docking hole 7-2-1 of the column cover 2, and then connect the nut 7-2 to the threaded connection end (at this time, the connecting piece is in a loose state, that is, the cam wrench 7-3 is rotated along the axial mounting portion until the length of the locking rod 7-1 inside the arc-shaped opening groove is the shortest, and the length of the locking rod 7-1 outside the cam wrench 7-3 is the longest, so that the nut 7-2 protrudes out of the nut receiving groove 2-2), then rotate the cam wrench 7-3 in the opposite direction so that the length of the locking rod 7-1 inside the arc-shaped opening groove gradually becomes the longest, and the length of the locking rod 7-1 outside the cam wrench 7-3 gradually becomes the shortest to firmly connect and fix the column cover 2 to the column 1. When it is necessary to detach the column cover 2 from the column body 1, it is only necessary to first reversely rotate the cam wrench 7-3 so that the length of the locking rod 7-1 located inside the arc-shaped opening groove gradually becomes the shortest, and the length of the locking rod 7-1 located outside the cam wrench 7-3 gradually becomes the longest so that the nut 7-2 extends out of the nut receiving groove 7-2-2, and then detach the nut 7-2 from the axial top of the locking rod 7-1, and finally pull the cam wrench 7-3 out of the wrench receiving groove 7-1-1. At this time, the column cover 2 and the column body 1 can be directly separated. When the connecting column needs to stack a combination of multiple columns 1 and column covers 2, it is only necessary to select a connector with a locking rod 7-1 of a suitable length. The connector is inserted from the wrench receiving groove 7-1-1 of the bottom column 1, and then extends from the locking rod docking hole 7-2-1 of the top cover body 2 to connect with the nut 7-2, and the disassembly process is the same. The column body 1 and the column cover 2 can be quickly assembled and disassembled by the connecting piece of this structure, and the structure after assembly is very stable and has high safety performance.

[0077] like Fig.12 and Fig.13As shown, the third embodiment of the connector of the present application comprises a toggle plate 9-1, a toggle plate mounting frame 9-2, a limit support frame 9-3 and a limit clamp 9-4. The bottom of the toggle plate 9-1 is provided with a finger groove, which is convenient for the user to apply force to the toggle plate 9-1. One end of the toggle plate mounting frame 9-2 is hinged to the back of the toggle plate 9-1, and the other end is rotatably connected to the column 1 through a rotating shaft 1. Specifically, the toggle plate mounting frame 9-2 comprises two bent racks, one end of the rack is provided with an axial hole 1 assembled and connected to the rotating shaft 1, and the rod body of the rack is provided with an axial hole 2 assembled and connected to the rotating shaft 2. The rack is hollowed out to reduce the weight of the entire connector. The limit support frame 9-3 is vertically arranged, and the bottom is rotatably connected to the frame body of the toggle plate mounting frame 9-2 through a rotating shaft 2. The limit clamp 9-4 is connected to the top of the limit support frame 9-3. The position-limiting support frame 9-3 includes a vertically arranged frame plate, the frame plate is provided with an inwardly concave arc-shaped vertical edge, the frame plate is provided with an axle-mounting hole at the bottom of the arc-shaped vertical edge for assembly and connection with the second rotating shaft, and the frame plate is connected to the position-limiting clamp 9-4 at the top of the arc-shaped vertical edge. The position-limiting support frame 9-3 of this structure is stable and reliable, and has a good use effect. Reinforcements can be provided on the edges and both sides of the frame plate to further improve the structural stability of the position-limiting support frame 9-3. The connecting member also includes a decorative plate 9-5 connected to the position-limiting support frame 9-3 and having a shape matching the accommodating groove, which can improve the aesthetics of the connecting column of the present application.

[0078] The column 1 is provided with a receiving groove for installing the connecting piece, the column cover 2 is provided with a column cover clamping groove 9-2-1 that docks with the receiving groove and is assembled and connected with the connecting piece of the column 1, and the column 1 is provided with a column clamping groove 9-1-1 at the bottom of the receiving groove that is assembled and connected with another connecting piece of the column 1. The two sides of the inside of the receiving groove are provided with shaft-mounted protrusions 9-1-2 that are assembled and connected with the rotating shaft 1, so that the toggle plate mounting frame 9-2 is connected to the column 1 through the rotating shaft 1.

[0079] When it is necessary to connect the column cover 2 with the column body 1, it is only necessary to place the column cover 2 on the top of the column body 1, and then rotate the toggle plate mounting frame 9-2 in the loosened state along the rotating shaft 1 until it is located in the accommodating groove. During the rotation, the toggle plate mounting frame 9-2 will drive the limiting clamp 9-4 to enter the column cover clamping groove 9-2-1 through the limiting support frame 9-3 (during the rotation of the toggle plate mounting frame 9-2, the limiting support frame 9-3 is always in a vertical state, and the toggle plate mounting frame 9-2 will rotate relative to the limiting support frame 9-3 through the rotating shaft 2, thereby driving the limiting support frame 9-3 to move its position). At this time, the connecting piece connects and fixes the column cover 2 to the column body 1. When it is necessary to separate the column cover 2 from the column body 1, it is only necessary to rotate the toggle plate mounting frame 9-2 in the locked state along the rotating shaft 1 to be located outside the accommodating groove. During the rotation, the toggle plate mounting frame 9-2 will drive the limiting clamp 9-4 to leave the column cover clamping groove 2-1 through the limiting support frame 9-3 (during the rotation of the toggle plate mounting frame 9-2, the limiting support frame 9-3 is always in a vertical state, and the toggle plate mounting frame 9-2 will rotate relative to the limiting support frame 9-3 through the rotating shaft 2, thereby driving the limiting support frame 9-3 to move in position). At this time, the column cover 2 and the column body 1 can be directly separated.

[0080] In addition, the angular range of rotation of the toggle plate mounting frame 9-2 along the rotation axis 1 can be limited. When the toggle plate mounting frame 9-2 rotates clockwise along the rotation axis 1 to the bottom, the toggle plate mounting frame 9-2 is exactly located in the receiving groove, and the limit support frame 9-3 and the limit clamp 9-4 are exactly clamped with the column cover clamping groove 9-2-1, so that the column cover 2 is connected and fixed to the column body 1; when the toggle plate mounting frame 9-2 rotates counterclockwise along the rotation axis 1 to the bottom, the toggle plate mounting frame 9-2 partially protrudes from the receiving groove, and the limit support frame 9-3 and the limit clamp 9-4 are exactly loosened from the column cover clamping groove 9-2-1, so that the column cover 2 can be separated from the column body 1. The toggle plate 9-1 and the toggle plate mounting frame 9-2 can be hinged, so that the toggle plate 9-1 can always be in a vertical state during the rotation of the toggle plate mounting frame 9-2, avoiding affecting the position movement of the limit support frame 9-3. The connecting piece of this structure can quickly disassemble and assemble the column 1 and the column cover 2, and the assembled structure is very stable and has high safety performance. The disassembly and assembly process of the column 1 and the column 1 is the same.

An axial body is provided at the bottom of the mounting frame 8-1, and the axial body is provided with an axial mounting hole. The wrench frame 8-2 includes a rotating plate connected to both sides of the axial body, and a connecting body connecting the two rotating plates, and the rotating plate is provided with an axial mounting docking hole docking with the axial mounting hole. The clamping frame 8-3 includes two vertically arranged support rods, an axial body 2 arranged at the bottom end of the support rod and connected to the back side of the two rotating plates, a limiting rod connecting the top ends of the two support rods, and a limiting plate body connecting the rod bodies of the two support rods, the limiting rod, the support rod, and the limiting plate body form a limiting bayonet, the axial body 2 is provided with an axial mounting hole 2, and the rotating plate is provided with an axial mounting docking hole 2 docking with the axial mounting hole 2. The axial body 2 is in the shape of a flat cylinder, and the support rod is tangentially connected to the outer peripheral wall of the axial body 2. The shaft-mounting hole and the shaft-mounting docking hole connect the rotating plate and the shaft-mounting body through the shaft body, so that the wrench frame 8-2 can rotate around the shaft-mounting hole of the mounting frame 8-1. The shaft-mounting hole 2 and the shaft-mounting docking hole 2 connect the shaft-mounting body 2 and the rotating plate through the shaft body 2, so that the clamping frame 8-3 can rotate around the shaft-mounting hole 2 of the wrench frame 8-2. The column 1 is provided with a receiving groove for installing the connecting member, and the column 1 is provided with a docking frame 8-1-1 connected to the mounting frame 8-1 at the top of the receiving groove, and a column limit clamping block 8-1-2 detachably connected to the limit clamping socket of another column 1 is provided at the bottom of the receiving groove. The column cover 2 is provided with a column cover limit clamping block 8-2-1 that docks with the docking frame 8-1-1 and is detachably connected to the limit clamping socket of the connecting member.

[0082] When the column cover 2 needs to be connected to the column body 1, it is only necessary to place the column cover 2 on the top of the column body 1, and then connect the mounting frame 8-1 of the connecting piece with the docking frame 8-1-1, and then rotate the wrench frame 8-2 in the horizontal state along the axial mounting hole to the vertical state. During the rotation, the wrench frame 8-2 will drive the clamping frame 8-3 to move so that its limiting clamping mouth will be clamped with the column cover limiting clamping block 8-2-1 (during the rotation of the wrench frame 8-2, the clamping frame 8-3 is always in a vertical state, and the wrench frame 8-2 will rotate relative to the clamping frame 8-3 through the second shaft body, thereby driving the clamping frame 8-3 to move in position).
