Detailed implementation mode
[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] As Figures 1 to 5 shown, the present invention provides a fixing mechanism for the production of dumbbell counterweight blocks, including a base 1. A side plate 2 is fixedly installed above the base 1. A servo motor 3 is fixedly installed at the rear of the side plate 2. A rotating shaft 4 extending to the inside of the side plate 2 is fixedly installed inside the servo motor 3. A connecting shaft 5 is movably installed inside the rotating shaft 4. A square plate 6 is fixedly installed on the outside of the connecting shaft 5. Elastic blocks 7 are evenly fixedly installed on the outside of the square plate 6. An elastic inclined surface ring 8 is fixedly installed on the outside of the elastic block 7. An outer ring block 9 located outside the elastic inclined surface ring 8 is fixedly installed on the outside of the square plate 6. A screw groove 10 is opened inside the outer ring block 9.
[0023] When it is necessary to fix the dumbbell counterweight block 19, insert the fixing ring 18 into the inside of the elastic block 7, and then rotate the turning knob 13. The turning knob 13 drives the threaded ring 11 to rotate inside the screw groove 10, thereby driving the snap ring 12 to move inward. The snap ring 12 moves inward to squeeze the side surface of the elastic inclined surface ring 8, causing the side surface of the elastic inclined surface ring 8 to contract inward under the squeezing force, so that the elastic inclined surface ring 8 clamps and fixes the outer wall of the fixing ring 18.
[0024] By inserting the fixing ring 18 into the inside of the elastic block 7 and then rotating the turning knob 13 to drive the snap ring 12 to move inward to squeeze the side surface of the elastic inclined surface ring 8, so that the elastic inclined surface ring 8 clamps and fixes the outer wall of the fixing ring 18. Compared with the traditional fixing mechanism for the production of dumbbell counterweight blocks, this fixing mechanism for the production of dumbbell counterweight blocks clamps and fixes the fixing ring 18 by the inward contraction of the elastic inclined surface ring 8, so that there is a certain gap between the elastic inclined surface ring 8 and the fixing ring 18 before fixing, which is convenient for fixing dumbbell counterweight blocks 19 with different radii.
[0025] Among them, a slot 14 is opened on the outer side of the rotating shaft 4, and card slots 15 are opened on both sides of the bottom of the slot 14. The connecting shaft 5 is movably connected inside the slot 14. Card blocks 17 are fixedly installed on both sides of the bottom of the connecting shaft 5. The card block 17 is located inside the card slot 15. A telescopic spring 16 is elastically installed at the bottom of the slot 14, and the telescopic spring 16 is located on the inner side of the card block 17.
[0026] When it is necessary to fix dumbbell counterweights 19 of different specifications, that is, when the shapes of the dumbbell counterweights 19 are quite different, the square plate 6 is pressed inwardly, so that the square plate 6 drives the connecting shaft 5 to move inwardly, drives the clamping block 17 to disengage from the inside of the clamping slot 15 to squeeze the telescopic spring 16, causing the telescopic spring 16 to deform, and then the square plate 6 is rotated to rotate the clamping block 17 to the bottom of the slot 14. At this time, the telescopic spring 16 releases its elastic potential energy to push the clamping block 17 out of the slot 14, thereby completing the replacement of the square plate 6.
[0027] By pressing the square plate 6 inward, the block 17 is disengaged from the slot 15 to squeeze the telescopic spring 16, and the square plate 6 is rotated to rotate the block 17 to the bottom of the slot 14. At this time, the telescopic spring 16 releases its elastic potential energy to push the block 17 out of the slot 14. Compared with the fixing mechanism of traditional dumbbell counterweights, the fixing mechanism of this dumbbell counterweight can complete the replacement of the square plate 6 by pressing and rotating.
[0028] A threaded ring 11 is installed on the internal thread of the screw groove 10 , and a clamping ring 12 is fixedly installed below the threaded ring 11 . The cross section of the clamping ring 12 is triangular, and the clamping ring 12 corresponds to the elastic bevel ring 8 .
[0029] The clamping ring 12 moves inward to squeeze the side surface of the elastic bevel ring 8 , so that the side surface of the elastic bevel ring 8 contracts inward due to the squeezing force, thereby allowing the elastic bevel ring 8 to clamp and fix the outer wall of the fixing ring 18 .
[0030] A turning button 13 is fixedly mounted on the outer side of the threaded ring 11 , and the turning button 13 is located on the outer side of the outer ring block 9 .
[0031] The knob 13 is rotated, and the knob 13 drives the threaded ring 11 to rotate inside the screw groove 10, thereby driving the clamping ring 12 to move inward.
[0032] A fixing ring 18 is movably mounted on the inner side of the square plate 6 , and a dumbbell weight block 19 located outside the rotating knob 13 is fixedly mounted on the outer side of the fixing ring 18 .
[0033] By clamping and fixing the fixing ring 18 , the dumbbell counterweight 19 is fixed, which makes it easier to process the dumbbell counterweight 19 .
[0034] A circular groove 20 is formed on the outer side of the dumbbell weight block 19 , and the circular groove 20 corresponds to the fixing ring 18 .
[0035] By providing a circular groove 20 on the front side of the dumbbell counterweight 19, it is convenient to insert the fixing ring 18 into the interior of the circular groove 20 for easy use.
[0036] Wherein, a control panel 21 is fixedly installed on the outer side of the base 1, and buttons 22 are uniformly fixedly installed on the outer side of the control panel 21.
[0037] The rotation speed of the servo motor 3 is controlled by the buttons 22, which facilitates the staff to perform processing such as painting on the outer side of the dumbbell counterweight 19.
[0038] The working principle and usage process of the present utility model are as follows:
[0039] When it is necessary to fix the dumbbell counterweight 19, insert the fixing ring 18 into the inner side of the elastic block 7, and then rotate the knob 13. The knob 13 drives the threaded ring 11 to rotate inside the thread groove 10, thereby driving the clamping ring 12 to move inward. The inward movement of the clamping ring 12 squeezes the side surface of the elastic inclined surface ring 8, causing the side surface of the elastic inclined surface ring 8 to contract inward under the squeezing force, so that the elastic inclined surface ring 8 clamps and fixes the outer wall of the fixing ring 18.
[0040] When it is necessary to fix dumbbell counterweights 19 of different specifications, that is, when there is a large difference in the shape of the dumbbell counterweights 19, press the square plate 6 inward, so that the square plate 6 drives the connecting shaft 5 to move inward, driving the clamping block 17 to disengage from the inside of the card slot 15 and squeezing the telescopic spring 16, causing the telescopic spring 16 to deform. Then rotate the square plate 6 to rotate the clamping block 17 to the lower side of the slot 14. At this time, the telescopic spring 16 releases its elastic potential energy to push the clamping block 17 out of the slot 14, thereby completing the replacement of the square plate 6.
