The sides of the mounting frame 1 are provided with baffles 4, and the baffles 4 are connected to the mounting frame 1 through a connecting assembly. The connecting assembly includes a mounting block 71, a connecting block 72, a rectangular groove 73 and a mounting groove 74.

The top surface of the connecting block 72 is provided with a limit groove 12, and the interior of the limit groove 12 is slidably connected with the fixing block 81, and the top surface of the fixing block 81 is welded with a sliding rod 82. The top of the mounting frame 1 is symmetrically provided with a placement groove 13, one end of the sliding rod 82 passes through the mounting frame 1 and extends to the internal welded limit block 83 of the placement groove 13, and the inner wall of the rectangular groove 73 is provided with a movable groove 14 located on the top surface of the fixing block 81, and the fixing block 81 is slidably connected to the movable groove 14, and a second spring 15 mounted on the surface of the sliding rod 82 is welded between the inner wall of the movable groove 14 and the top surface of the fixed block 81.

[0024] During assembly, the operator pulls up the limit block 83 by hand to make the sliding rod 82 slide and move accordingly. When the sliding rod 82 moves, the fixing block 81 is driven to enter the movable groove 14. At the same time, the movement of the fixing block 81 causes the second spring 15 to be compressed and deformed. Then the baffle 4 is picked up in turn and the mounting block 71 and the connecting block 72 are respectively inserted into the mounting groove 74 and the rectangular groove 73. At this time, the force applied to the limit block 83 is released, and the second spring 15 resets and rebounds so that the fixing block 81 is in the limit groove 12, thereby fixing the connecting block 72 inserted in the rectangular groove 73, and then stably fixing the baffle 4 and the side of the mounting frame 1 to prevent the baffle 4 from detaching from the side of the mounting frame 1.

The inside of the plug-in slot 94 is slidably connected to the rubber pad 17 located at the end of the connecting plate 92, and a plurality of equidistantly distributed third springs 18 are fixedly connected between the side of the rubber pad 17 away from the connecting plate 92 and the inner wall of the plug-in slot 94, and the end of the connecting plate 92 conflicts with the side of the rubber pad 17.

[0026] During assembly, the connecting plate 92 is inserted into the plug-in slot 94 opened on one side of the plug-in plate 93 through the splicing plate 91, so that the splicing plate 91 and the plug-in plate 93 are aligned with each other, so that the two ends of one side of the baffle 4 are spliced ​​and fixed together, so that the end of the resistor band 2 that is not inserted into the card slot 3 can be fixed and clamped, and it can be prevented from being out of the card slot 3 due to flipping in position. When the connecting plate 92 is inserted into the plug-in slot 94, the connecting plate 92 squeezes the rubber pad 17 and the third spring 18, and under the elastic action of the third spring 18, the rubber pad 17 is tightly connected to the connecting plate 92, and at the same time, the fastening hole 16 on the side of the plug-in plate 93 is aligned with the fastening hole 16 on the side of the connecting plate 92, and then the fastening bolts 95 are rotated into the fastening holes 16 in turn for fixing, so that the connection between the splicing plate 91 and the plug-in plate 93 can be made tighter and firmer during assembly.

[0027] A rectangularly distributed screw rod 5 is welded to the other side of the baffle 4, and the surface of the screw rod 5 is slidably connected to the surface of the side plate 6. A first spring 10 sleeved on the outer surface of the screw rod 5 is provided on the side of the side plate 6 away from the baffle 4. One end of the screw rod 5 is connected to a nut 11 located on the side of the first spring 10 by threaded rotation. During assembly, the side plate 6 is first moved to the side of the baffle 4 through the screw rod 5, and then the first spring 10 is sequentially sleeved on the outer surface of the screw rod 5, and then the nut 11 is fixed to the outer surface of the screw 5 by threaded rotation, so that the side plate 6 and the side of the baffle 4 are fixed together by the nut 11, and at the same time, under the elastic action of the first spring 10, the side plate 6 and the baffle 4 can be tightly connected, the structure is simple, and the assembly is convenient.

[0028] Working principle: the operator first inserts the resistance band 2 into the corresponding slot 3 in sequence, then picks up one of the baffles 4 to insert the mounting block 71 and the connecting block 72 into the mounting slot 74 and the rectangular slot 73, and when the connecting block 72 is in the rectangular slot 73, the limiting block 83 is pulled upwards through the slide bar 82 to allow the fixing block 81 to enter the movable slot 14, and then the limiting block 83 is released. At this time, the second spring 15 is reset and rebounded to drive the fixing block 81 into the limiting slot 12 to fix the connecting block 72, thereby stably fixing the baffle 4 to the side of the mounting frame 1, and then Then pick up another baffle 4 and repeat the operation. At the same time, insert the connecting plate 92 welded at one end of the splicing plate 91 into the corresponding plug-in slot 94. At this time, the connecting plate 92 squeezes the rubber pad 17 and the third spring 18. At the same time, align the side fastening holes 16 of the plug-in plate 93 with the side fastening holes 16 of the connecting plate 92, rotate the fastening bolts 95 into the fastening holes 16 for fixing, and then move the side plate 6 through the screw 5 to the side of the baffle 4, and then put the first spring 10 on the screw 5 in turn, and then rotate the nut 11 to fix it on the screw 5 to complete the assembly work.
