The positioning pins 114 and the guide grooves 116 correspond to each other, so that the barbell plate assemblies 200 positioned in the positioning pins 114 and the guide grooves 116 are aligned with each other.

[0026] Reference Figure 9 , 10 , one side of the inner side of one notch 217 is provided with a notch 215, the notch 215 is provided with an inclined surface 216 close to one side of the middle hole 212, one barbell plate assembly 200 on the upper part of the platform 115 is pushed into the barbell plate assembly 200 on one side of the barbell plate slot 113, when the two barbell plates 210 form a circle, the two clamping rings 220 inside also form a circle, the combination surface of the barbell plate 210 and the combination surface of the two clamping rings 220 coincide, at this time the clamping ring 220 loses the block, the spring 230 pulls the corresponding clamping ring 220 to rotate, the combination surface of the two clamping rings 220 and the combination surface of the two barbell plates 210 no longer coincide, the two clamping rings 220 combine the two barbell plates 210 together, the two barbell plate assemblies 200 form a complete barbell plate that cannot be separated. The barbell plate 210 is a semicircular disc structure, the clamping ring 220 is a semicircular ring structure, when the combination surface of the barbell plate 210 and the combination surface of the two clamping rings 220 coincide, the two barbell plate assemblies 200 can be separated from each other, if the spring 230 pulls the corresponding clamping ring 220 to rotate, the combination surface of the two clamping rings 220 and the combination surface of the two barbell plates 210 no longer coincide, the two clamping rings 220 combine the two barbell plates 210 together, the two barbell plate assemblies 200 form a complete barbell plate that cannot be separated, realizing the quick replacement of the barbell plate.

[0027] Reference Figure 2 , the barbell handle 120 is inserted through the circular hole formed by the clamping ring hole 221 in the middle of the two clamping rings 220, the key 121 on the barbell handle 120 is inserted through the key groove 222 of the clamping ring hole 221, and the combined barbell plate and barbell handle 120 are taken out from the side plate slot 112 on both sides of the rack 110.

[0028] Referring to Figure 4 , the combined set of barbells is connected by bolts on both sides, and the bolts pass through the corresponding screw holes 122. A set of barbells on the same side is positioned in two bolts.

[0029] Referring to Figure 6 , 7 , 8, 9, 10, when installing the barbells, one barbell assembly 200 on the upper part of the platform 115 is pushed into the barbell assembly 200 on one side of the barbell groove 113. The corresponding snap ring 220 is guided by the slope 216 to approach the barbell assembly 200 on one side of the barbell groove 113. When the two barbells 210 overlap, the snap ring 220 on one side of the platform 115 enters the slot 217 in the barbell 210 on one side of the barbell groove 113 from the guide groove 116. The barbell assembly 200 continues to slide, and the end surface of the snap ring 220 on one side of the platform 115 contacts the slope 216 of the barbell 210 in the barbell groove 113. The end surface of the snap ring 220 on one side of the barbell groove 113 contacts the slope 216 on one side of the platform 115. Continue to push the barbell assembly 200 on one side of the platform 115. The two snap rings 220 rotate under the action of the corresponding slopes 216. The corresponding springs 230 are stretched. When the end surfaces of the two snap rings 220 slide over the corresponding slopes 216, the end surfaces of the two snap rings 220 are horizontal. Continue to push the barbell assembly 200 on one side of the platform 115. When the two barbells 210 form a circle, the two snap rings 220 inside also form a circle. The joint surface of the barbell 210 coincides with the joint surface of the two snap rings 220. At this time, the snap ring 220 loses the block, and the spring 230 pulls the corresponding snap ring 220 to rotate. The joint surface of the two snap rings 220 no longer coincides with the joint surface of the two barbells 210. The two barbell assemblies 200 form a complete barbell that cannot be separated. The combination of the required barbells is completed according to the above method.

[0030] When reducing the barbells, the combined barbells and barbell handle 120 are placed into the side plate groove 112 at the bottom of the rack 110 on both sides. The corresponding positioning pin 114 is clamped in the slot 217. Rotate the barbell handle 120, and the barbell handle 120 drives the connected snap ring 220 to rotate. When the contact surface of the same group of snap rings 220 rotates to coincide with the contact surface of the same group of barbells 210, push the barbell 210 on the upper part of the barbell assembly 200 on one side of the platform 115 to separate the two barbell assemblies 200 that make up the barbells. The above device makes it convenient and fast to replace the barbells. The trainer does not need to move directly to replace the barbells, which is convenient, fast and safe.
