When the athlete does not need to take exercise, the athlete releases the barbell, then the athlete gets up from the bottom plate 1, and then the driving mechanism 15 is controlled to drive the upper part of the swinging rod 10 to swing outwards, so that the clamping rod 8 is driven to swing outwards to be separated from the helical rack 7, the first spring 9 is compressed, the helical rack 7 resets downwards under the action of the gravity of the helical rack 7, and the barbell resets downwards along with the helical rack. After resetting, the athlete stops controlling the driving mechanism 15, under the action of the first spring 9, the clamping rod 8 swings inwards to be matched with the clamping rod 8, and the athlete can take out the barbell from the placing sleeve 13.
When the athlete does not need to take exercise, the athlete steps on the pedal 151 downwards, the upper part of the swinging rod 10 is driven to swing outwards through the pull wire 152, so that the clamping rod 8 is driven to swing outwards to be separated from the helical rack 7, the first spring 9 is compressed, the helical rack 7 resets downwards under the action of the gravity of the helical rack 7, and the barbell resets downwards along with the helical rack. And (5) resetting. The player releases the pedal 151 and the catch lever 8 swings inwardly into engagement with the catch lever 8 under the action of the first spring 9.
The sportsman stimulates left pull ring 164 left, drives left inserted bar 167 and moves left, makes left inserted bar 167 shift out in the left jack 166, and left second spring 165 is stretched this moment, and the sportsman shifts up or down left stop collar 161 again, adjusts the distance between left side stop collar 161 and the left side stopper 141 to can adjust the distance that left side sliding sleeve 11 reciprocated, and then can be applicable to different sportsman. After the adjustment is completed, the player makes the left insertion rod 167 correspond to the corresponding left insertion hole 166, then releases the left pull ring 164, under the action of the left second spring 165, the left pull ring 164 resets to the right, the left insertion rod 167 resets to the right and is inserted into the corresponding left insertion hole 166, the left limiting sleeve 161 is fixed, the player pulls the right pull ring 164 to the right to drive the right insertion rod 167 to move to the right, the right insertion rod 167 moves out of the right insertion hole 166, at the moment, the right second spring 165 is stretched, and then the right limiting sleeve 161 is shifted upwards or downwards to adjust the distance between the right limiting sleeve 161 and the right limiting block 141. After the adjustment, the player makes the right insertion rod 167 correspond to the corresponding right insertion hole 166, and then releases the right pull ring 164, under the action of the right second spring 165, the right pull ring 164 is reset to the left, and the right insertion rod 167 is reset to the left and inserted into the corresponding right insertion hole 166, so as to fix the right stop collar 161.
After the player puts the barbell in placing cover 13, the contact of barbell and rubber block 17 screws up screw rod 19 again, fixes the barbell, prevents that the barbell from skidding, and the contact of barbell and rubber block 17 can be better prevent that the barbell from skidding. When the barbell needs to be taken out from the placing sleeve 13, the athlete loosens the screw rod 19.
When swing rod 10 upper portion outwards swung, drive swing rod 10 to being swung inwards to drive sleeve pipe 20 and inwards move, drive rubber slab 22 through shell fragment 23 and inwards move and slide rail 6 contact, thereby can increase frictional force, reduce the speed of slide rail 6 lapse, thereby can reduce barbell lapse speed, avoid the too fast barbell lapse that leads to the barbell to collide bottom plate 1, thereby lead to barbell or bottom plate 1 impaired.
While the disclosure has been described with respect to a limited number of embodiments, those skilled in the art, having benefit of this disclosure, will appreciate that various other embodiments can be devised which do not depart from the scope of the invention as disclosed herein. Accordingly, the scope of the invention should be limited only by the attached claims.
