Therefore, the trainer can select the second spring 42 that suits him or her according to the requirements of the trainer. The adjustment of training intensity can be completed by moving the contact plate 52 to above different slots 41. The top plate 43 of the second spring 42 is fixedly installed. When the contact plate 52 is moved to one of the slots where the second spring 42 is not installed, In the slot 41, if the athlete wants to pull the sliding sleeve through the tension ring, he only needs to overcome the force of the first spring 37, and the exercise intensity is relatively small.

In a preferred technical solution of this embodiment, side plates 34 are fixedly installed on both sides of the sliding sleeve 31 , a fixing ring 35 is fixedly installed at the bottom of the side plate 34 , and a pulley is fixedly installed at the bottom of the fixing ring 35 . Rope 36. A tension ring 38 is fixedly installed at the bottom end of the pull rope 36. The exerciser holds the tension ring 38 and can pull the sliding sleeve 31 to move downward through the pull rope 36. When the pull rope 36 is released, the sliding sleeve 31 It will move upward again under the elastic force of the first spring 37 .

In a preferred technical solution of this embodiment, a rope hole is provided on the surface of the bottom plate 20 for the drawstring 36 to pass through.

In a preferred technical solution of this embodiment, the diameter of the contact plate 52 is equal to or smaller than the inner diameter of the slot 41 , so that the contact plate 52 can squeeze the top plate 43 and thereby squeeze the second spring 42 .

Example 2

Please refer to Figures 1-4. The present utility model provides a technical solution: a physical training device, including a mounting plate 10. Screw holes are provided on the surface of the mounting plate 10. The mounting plate 10 can be installed and fixed through the screw holes. A column 30 is fixedly installed at the bottom of the mounting plate 10, a base plate 20 is fixedly installed at the bottom of the column 30, adjustment boxes 40 are fixedly installed on both sides of the top of the base plate 20, and a sliding sleeve 31 is set outside the column 30. The sliding sleeve 31 can move up and down outside the column 30. The second spring 42 is fixedly installed at the bottom of the sliding sleeve 31. The bottom end of the second spring 42 is fixedly connected to the bottom plate 20, and the second spring 42 is sleeved on the column. 30 Outside, support plates 32 are fixedly installed on both sides of the sliding sleeve 31. A chute 33 is provided on the surface of the support plate 32. An adjustment component 50 for adjusting training intensity is provided inside the chute 33. The adjustment component 50 includes a limit plate 53, which is slidably installed on the bottom end of the support plate 32. A threaded rod 54 is fixedly installed on the top of the limit plate 53. The outside of the threaded rod 54 penetrates the chute 33 and is threaded with a fastener. nut 55, so the threaded rod 54 can move in the chute 33. A straight rod 51 is fixedly installed at the bottom of the limit plate 53, and a contact plate 52 is fixedly installed at the bottom of the straight rod 51.

Further, if you need to increase the intensity of training, you only need to loosen the fastening nut 55, then pull the straight rod 51 to move on the support plate 32, move the contact plate 52 to above the corresponding slot 41, and then tighten the fastening nut 55. The contact plate 52 can be fixed by tightening the fixing nut 55. Therefore, when the sliding sleeve 31 is pulled to move downward, the contact plate 52 will be inserted into the slot 41, and at the same time, the contact plate 52 will act on the top plate 43, so that the contact plate 52 can be fixed. The second spring 42 is squeezed, so if the athlete wants to pull the sliding sleeve 31 through the tension ring 38 at this time, he needs to overcome the joint force of the first spring 37 and the second spring 42, and the exercise intensity increases, so the exerciser can Adjust the training intensity according to your own requirements.

In the preferred technical solution of this embodiment, four slots 41 are provided inside the adjustment box 40 along the length direction of the bottom plate 20 . The inner diameter of the slots 41 is consistent with the diameter of the top plate 43 . Three of them are A second spring 42 is fixedly installed inside the slot 41, and the elastic force of the second spring 42 in each slot 41 is the same. A top plate 43 is fixedly installed at the top of the second spring 42. When the adjustment components 50 move toward each other, , the adjustment component 50 will move to the top of the slot 41 without the second spring 42. At this time, if the athlete wants to pull the sliding sleeve through the tension ring, he only needs to overcome the force of the first spring 37, and the training intensity will be reduced, while the adjustment component will When 50 deviates from this, the adjustment component 50 will move above the slot 41 with the second spring 42, and the training intensity will increase. At this time, if the athlete wants to pull the sliding sleeve through the tension ring, he must overcome the first spring 37 and the second spring 42. force, the exercise intensity is relatively increased.

Working principle: When in use, if you need to increase the intensity of training, just loosen the fastening nut 55, then pull the straight rod 51 to move on the support plate 32, and move the contact plate 52 above the corresponding slot 41. Then tighten the fastening nut 55 to fix the contact plate 52. Therefore, when the sliding sleeve 31 is pulled to move downward, the contact plate 52 will be inserted into the slot 41, and at the same time the contact plate 52 will act on the top plate 43. , the second spring 42 can be squeezed. Therefore, if the athlete wants to pull the sliding sleeve 31 through the tension ring 38 at this time, he needs to overcome the joint force of the first spring 37 and the second spring 42, and the exercise intensity increases, so the Exercisers can adjust the training intensity according to their own requirements.

The above embodiments are only for illustrating the technical concepts and features of the present invention. Their purpose is to enable those familiar with the technology in this field to understand the content of the present invention and implement it, and cannot limit the scope of protection of the present invention. All equivalent changes or modifications based on the spirit and essence of the present utility model shall be included in the protection scope of the present utility model.
