[0002] Dumbbells are fitness aids used to enhance muscle strength. They typically consist of a handle in the middle and weight-bearing sections at both ends, and come in two types: fixed weight and adjustable weight. Fixed weight dumbbells are mostly solid designs made of cast iron or with a rubber coating, while adjustable dumbbells are similar to smaller barbells, with the weight adjusted by adding or removing weight plates. During dumbbell manufacturing, drilling is usually required to facilitate subsequent assembly; however, existing drilling equipment still presents some problems in practical use.

[0003] For example, application number CN201721157388.1 relates to a miniature CNC punching machine for punching discs. It includes a base, a pad on the base, a disc fixing device on the pad, and support frames on the left and right sides of the base.

[0030] Combination Figures 1-4 A drilling device for processing dumbbells in fitness equipment includes a drilling device body 1 and a telescopic cylinder 11 fixedly connected to the top of the drilling device body 1. A sliding frame 12 is slidably connected to the inner side of the drilling device body 1. A connecting plate 111 is fixedly connected to the output end of the telescopic cylinder 11. A drilling component 112 is provided on the connecting plate 111. The drilling device body 1 is provided with a placement structure for placing multiple sets of dumbbells. The placement structure includes a motor 121 fixedly connected inside the drilling device body 1. A sliding block 13 is also slidably connected inside the drilling device body 1.

[0031] The present invention will be further described below with reference to the embodiments.

[0032] Example 1:

[0033] To address the problem that existing dumbbell punching devices often lack effective safety warning structures, and that accidental activation during punching operations could pose a risk of injury to workers placing dumbbells, this embodiment discloses the following technical solution, specifically as follows: Figures 1-4As shown, a ventilation port for ventilation of motor 121 is provided on one side of the drilling equipment body 1. A transmission screw 122 is fixedly connected to the output end of motor 121. A limit block 123 is threadedly connected to the transmission screw 122. The limit block 123 is fixedly connected to the sliding frame 12. A spring rod 131 is fixedly connected to one end of the sliding block 13. One end of the spring rod 131 is fixedly connected to the inside of the drilling equipment body 1. Trapezoidal blocks 132 are slidably connected to both ends of the sliding block 13, and the two sets of trapezoidal blocks 132 are slidably connected to the drilling equipment body 1. Inside, a baffle 133 is fixedly connected to the top of the trapezoidal block 132. The baffle 133 is located below the connecting plate 111. A placement slot 14 is provided on the top of the sliding frame 12. When in use, the operator can start the motor 121 located inside the drilling equipment body 1. The motor 121 drives the transmission screw 122 to rotate, thereby causing the limiting block 123 to move. The limiting block 123 drives the sliding frame 12 to move, thereby causing the sliding frame 12 to move out of the drilling equipment body 1. The dumbbell to be processed can be placed in the placement slot 14 on the sliding frame 12. Inside 4, motor 121 can be activated to move sliding frame 12 into the interior of drilling equipment body 1. When sliding frame 12 moves to a certain position, it will press against sliding block 13. The movement of sliding block 13 will cause the two sets of trapezoidal blocks 132 to move. The two sets of trapezoidal blocks 132 will drive the two sets of baffles 133 to move respectively. After the operator observes that the baffles 133 have completely moved away from under the connecting plate 111, the telescopic cylinder 11 can be activated. The telescopic cylinder 11 drives the connecting plate 111 to move, and the connecting plate 111 drives multiple sets of drilling... The hole assembly 112 moves, causing its bottom end to contact the dumbbell, thus activating the drilling assembly 112 to drill holes in the dumbbell. If the sliding frame 12 does not move to the designated position, the sliding block 13 will cause the trapezoidal block 132 to move under the action of the spring rod 131, thereby placing the two sets of baffles 133 below the connecting plate 111. This can remind the staff that the sliding frame 12 is not in the correct position, thus providing a safety reminder to the staff and further improving the subsequent drilling operation.

[0034] Example 2:

[0035] To address the problem that existing dumbbell punching devices often rely on a single spring clamp to hold the dumbbell in place, which can easily lead to loosening during processing, this embodiment discloses the following technical solution, specifically as follows: Figure 4 and Figure 5As shown, multiple sets of placement slots 14 and connecting plates 111 are provided. A knob 141 is rotatably connected to one side of the sliding frame 12. Two sets of knobs 141 are provided. One end of the knob 141 is fixedly connected to a bevel gear 142. A bevel gear 143 is meshed with one side of the bevel gear 142. The bevel gear 143 is rotatably connected inside the sliding frame 12. A threaded screw 144 is fixedly connected to one side of the bevel gear 143. Sliding plates 145 are threaded to both ends of the threaded screw 144. The sliding plates 145 are slidably connected inside the sliding frame 12. A clamping block 146 is fixedly connected to the sliding plate 145. Two sets of sliding plates 145 are provided. A collection chamber 15 is fixedly connected to the bottom of the drilling device body 1. The interior of the collection chamber 15 can... The dumbbell is equipped with a pull-out box 151. After placing the dumbbell inside the placement slot 14, the knob 141 located on one side of the sliding frame 12 can be rotated. The knob 141 drives the first bevel gear 142 to rotate, which in turn drives the second bevel gear 143 to rotate. The second bevel gear 143 drives the positive and negative thread screws 144 to rotate, which in turn moves the two sets of sliding plates 145. The sliding plates 145 drive the clamping block 146 to move, which can clamp the dumbbell and prevent it from shaking significantly. The processing debris can enter the collection chamber 15 through the hole at the bottom of the sliding frame 12. The pull-out box 151 inside the collection chamber 15 can further collect the debris, achieving a more stable fixation of the dumbbell and improving the efficiency of use.
