[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] like Figure 1-5As shown, a children's sports exercise equipment includes a base 1 symmetrically arranged on the left and right sides. Support columns 201 are symmetrically arranged at the front and back of the base. The support columns are bolted to the base. An exercise mechanism 2 is slidably connected to the top of the four support columns. Guide columns 203 are arranged at the four corners of the exercise mechanism. A guide hole is opened at the upper center of the support column for the guide column to slide into. A positioning mechanism is installed between the outer sides of two support columns on the same base. To achieve rapid height adjustment between the support columns and guide columns, the specific connection method between the support columns and guide columns is as follows: an inclined clearance groove 202 is opened on the side of the support column away from the center of the exercise mechanism. The inclined clearance groove runs through both the front and back sides of the support column, and the bottom of the groove communicates with the guide hole. The opening of the inclined clearance groove is at the top, and the bottom is at the bottom. Several inclined slots 205 are spaced from top to bottom on the side of the guide column away from the center of the exercise mechanism. The inclined slot extends through both the front and rear sides of the guide column. The inclined slot has its opening at the bottom and its bottom at the top. The positioning mechanism engages between the cooperating inclined slot and the inclined clearance slot. The positioning mechanism includes a horizontally positioned positioning rod 206. The two ends of the positioning rod are respectively engaged in the bottom of the inclined clearance slots of the two support columns on the same base. The inclined slot engages in the rod section area of ​​the positioning rod located in the guide hole. That is, when fixedly connected: the positioning rod engages in the bottom of the inclined clearance slot due to its own weight, limiting the lower side of the positioning rod. At the same time, the guide column engages the bottom of the inclined slot on the positioning rod due to gravity, limiting the upper side of the positioning rod, thus achieving the circumferential limitation of the positioning rod. When the height needs to be changed, simply lift the guide column slowly, allowing the positioning rod to slide out of the inclined clearance slot gradually through the inclined slot. Then, raise and lower the guide column until the inclined slot and inclined clearance slot of the required height are engaged, and then secure it with the positioning rod to achieve the height change.

[0027] In this embodiment, to prevent the end of the positioning rod from sliding out of the front or rear end of the corresponding inclined clearance groove, the two ends of the positioning rod extend out of the front or rear end of the corresponding inclined clearance groove, and a limiting block 208 is provided on the extended end. The limiting block is used to abut against the front or rear side of the support column. The positioning rod can be limited by the limiting block to prevent the positioning rod from coming out during use and to achieve axial limitation of the positioning rod.

[0028] In this embodiment, to further secure the connection between the support column and the base, a fixing seat 3 is symmetrically arranged on the base. The fixing seat includes an L-shaped mounting plate with the horizontal part at the bottom and the vertical part at the top. The horizontal part of the L-shaped mounting plate is fixed to the base, and the vertical part of the L-shaped mounting plate is fixed to the lower side of the support. Reinforcing ribs are symmetrically arranged between the horizontal and vertical parts of the L-shaped mounting plate. The fixing seat can reinforce the support column, increase its stability, and prevent it from shaking.

[0029] In this embodiment, for the sake of reasonable design, several pins 102 are arranged in an array under the base. When the base is installed, the pins are inserted into the ground to reinforce the connection between the base and the ground and prevent the base from shaking. Several storage slots 101 are located in the middle of the upper surface of the base between the front and rear support columns. The storage slots can store the disassembled connecting crossbars to prevent them from being lost during use.

[0030] In this embodiment, for the sake of reasonable design, an L-shaped hook 5 is provided on the side of the support column. The L-shaped hook can be used to hang clothes conveniently and prevent them from getting dirty when they fall to the ground.

[0031] In this embodiment, for the sake of reasonable design, the exercise mechanism includes horizontal connecting rods 204 arranged symmetrically on the left and right. The two ends of the horizontal connecting rods are respectively fixedly connected to the upper ends of the front and rear support columns on the same side. A horizontal connecting crossbar 207 is arranged between the two horizontal connecting rods from front to back. The connecting crossbar is a detachable connection. When the connecting crossbar is removed, only the two horizontal connecting rods on the left and right are left, which can be used as a single bar or a parallel bar. When the connecting crossbar is installed, the exercise mechanism becomes a ladder-style exercise mechanism.

[0032] In this embodiment, in order to achieve a detachable connection between the connecting crossbar and the horizontal connecting rod, the connecting crossbar is perpendicular to the horizontal connecting rod, and connecting blocks 6 are provided at both ends of the connecting crossbar. The connecting blocks are provided with vertical connecting holes 211. The connecting blocks are fixed to the bottom of the horizontal connecting rod by bolts 210. The bolt head is at the bottom and abuts against the end face of the connecting block on the lower outer periphery of the connecting hole. The threaded section of the bolt passes through the connecting hole and is screwed to the bottom of the horizontal connecting rod. That is, the horizontal connecting rod is provided with a screw hole 209 corresponding to the bolt.

[0033] In this embodiment, in order to facilitate gripping, an anti-slip sleeve 4 is provided on the middle part of the connecting crossbar. The anti-slip sleeve can increase the surface friction of the connecting crossbar and prevent the hand from slipping when gripping the connecting crossbar.

[0034] In this embodiment, during use, the bolts on the connecting block are rotated to move them out of the screw holes, releasing the positioning of the connecting crossbar. Then, the connecting crossbar is placed inside the storage slot for storage. Subsequently, the bolts that were just removed are screwed back into the screw holes, allowing the two horizontal connecting rods to form a parallel bar under the support of the guide posts. Alternatively, the guide posts on one of the bases can be removed to form a single bar, allowing children to exercise using either the parallel or single bar. Without removing the connecting crossbar, pushing it upwards removes the positioning rod from the inclined slot and inclined clearance slot, releasing the positioning of the guide post. Then, pushing the connecting crossbar upwards again, when a suitable height is reached, the positioning rod is placed back into the inclined slot and inclined clearance slot to position the guide post. At this point, the connecting crossbar is at a high position, forming a ladder, allowing children to exercise using this ladder.
