Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically a training dumbbell with protective components. Background Technology

[0002] Dumbbells are auxiliary equipment used in weightlifting and fitness exercises. They are smaller than barbells and are mainly made of cast iron with a rubber coating. They are primarily used for training to enhance muscle strength. Currently, the most common types of training dumbbells on the market are fixed weight dumbbells and adjustable weight dumbbells. Adjustable weight dumbbells are more flexible and convenient to use.

[0003] Current adjustable dumbbells achieve this by attaching and removing weight plates of different weights on both sides of the dumbbell head. However, during adjustment, users often forget the weight of a single dumbbell plate and blindly increase or decrease the number of plates, causing the weight to exceed the trainee's tolerance after adjustment. This can lead to muscle strain when using overweight dumbbells. In addition, with existing dumbbells, the trainee's palm needs to be in contact with the dumbbell handle, making the handle surface prone to accumulating oils and sweat from the trainee. If not cleaned promptly, this can affect the normal use of the dumbbell. Utility Model Content

[0004] The purpose of this invention is to provide a training dumbbell with protective components to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a training dumbbell with protective components, including an electronic scale. A vertical frame is provided at the top of the scale pan. Arc-shaped openings are provided on both sides of the top of the vertical frame. A locking half-ring is provided at the top of each arc-shaped opening. An external gear is rotatably connected to the center of the inner side of each arc-shaped opening. A handle is provided inside the arc-shaped opening. Dumbbell plates are fitted at both ends of the handle. A grip is wrapped around the center of the handle. Gear rings are provided on both sides of the grip. Linear guide rails are installed on the inner walls of both sides of the vertical frame. A slider is slidably connected to the center of each linear guide rail. An arc-shaped plate is provided at the bottom of the grip.

[0006] Preferably, both sides of the bottom end of the card half ring are fixedly connected with card blocks, and both sides of the top end of the arc-shaped opening are provided with card slots. The card blocks are engaged with the card slots, and the card half ring is engaged with the arc-shaped opening through the card blocks.

[0007] Preferably, a rotary motor is fixedly installed on the top of one side wall of the vertical frame, and the output end of the rotary motor is engaged with the middle of one of the external gears.

[0008] Preferably, the gear ring is fixedly connected to the handle, the gear ring is meshed with the external gear, and the handle is rotatably connected to the arc-shaped opening through the gear ring.

[0009] Preferably, a towel piece is fixedly connected to the top of the arc-shaped plate, the arc-shaped plate is slidably connected to the vertical frame via a linear guide rail, and the arc-shaped plate is in contact with the bottom of the grip via the vertical frame.

[0010] Preferably, a sweat-absorbing pad is embedded at the bottom of the vertical frame.

[0011] Preferably, the electronic scale has side base plates fixedly connected to both sides of its side walls.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This training dumbbell with protective components, through its arc-shaped opening, locking half-ring, vertical frame, and electronic scale, allows the handles to be placed on the arc-shaped opening when the weight needs to be adjusted. The locking half-ring then locks both sides of the handles to the vertical frame, ensuring that the other end of the dumbbell remains on the vertical frame when adding or removing weight plates. After the weight adjustment is complete, the electronic scale at the bottom of the vertical frame can directly read the adjusted weight, thus preventing the dumbbell weight from exceeding the trainee's capacity and reducing the probability of muscle strain when using the dumbbell.

[0014] 2. This training dumbbell with protective components uses a gear ring, external gear, rotary motor, and arc plate. After use, the gear ring on the dumbbell handle meshes with the external gear, causing it to rotate on the vertical frame. This allows the grip sleeve on the handle to rotate and rub against the arc plate attached to the bottom surface of the grip sleeve, wiping away any residual oil and sweat from the grip sleeve surface. This reduces the amount of residual oil and sweat on the handle and minimizes any adverse effects on the dumbbell's subsequent normal use. Attached Figure Description

[0023] like Figures 1 to 4 As shown, this embodiment of the training dumbbell with protective components includes an electronic scale 11. A vertical frame 9 is provided at the top of the scale pan of the electronic scale 11. An arc-shaped opening 6 is provided on both sides of the top of the vertical frame 9. A half-ring 7 is provided at the top of the arc-shaped opening 6. An external gear 13 is rotatably connected to the middle of the inner side of the arc-shaped opening 6. A handle 1 is provided inside the arc-shaped opening 6. Dumbbell plates 2 are sleeved on both ends of the handle 1. A grip sleeve 3 is wrapped in the middle of the handle 1. Gear rings 8 are provided on both sides of the grip sleeve 3. Linear guide rails 5 are installed on both inner walls of the vertical frame 9. A slider 14 is slidably connected to the middle of the linear guide rail 5. An arc-shaped plate 4 is provided at the bottom of the grip sleeve 3.

[0024] Specifically, the electronic scale 11 mainly consists of a weighing pan, a sensor, and an electronic display instrument. After being powered on, it can instantly read the weight of the object placed on the weighing pan. The cross-section of the vertical frame 9 is a triangular structure, which has good stability. This allows the handle 1, placed on the vertical frame 9 through the arc-shaped opening 6, to also maintain good stability. The function of the locking half-ring 7 is to close the originally open arc-shaped opening 6, so that the handle 1 placed in the arc-shaped opening 6 can be temporarily limited within the arc-shaped opening 6, thereby facilitating the subsequent loading and unloading of dumbbell plates 2 on the handle 1 and reducing the probability of the handle 1 disengaging from the arc-shaped opening 6. The external gear 13 meshes with the gear ring 8, which allows the handle 1 to rotate under the action of the gear ring 8, thereby realizing the rotation of the handle 1 on the top of the vertical frame 9. The grip sleeve 3 is made of silicone material, which is non-slip and wear-resistant. The function of the linear guide rail 5 is to realize the up and down movement of the arc plate 4, so that when the handle 1 is placed on the arc-shaped opening 6 of the vertical frame 9, it is not easy to cause interference to the handle 1. The curvature of the top surface of the arc plate 4 matches the surface curvature of the grip sleeve 3.

[0025] Furthermore, the bottom of the half-ring 7 is fixedly connected to both sides with locking blocks, and the top of the arc-shaped opening 6 is provided with locking grooves on both sides. The locking blocks and the locking grooves are engaged and connected. The half-ring 7 is engaged and connected to the arc-shaped opening 6 through the locking blocks. The half-ring 7 is a detachable structure, which allows the handle 1 to be easily removed from the vertical frame 9.

[0026] Furthermore, a rotary motor 15 is fixedly installed on the top of one side wall of the vertical frame 9. The output end of the rotary motor 15 is engaged with the middle of one of the external gears 13. After the rotary motor 15 is powered on, it can drive the external gear 13 to rotate, thereby realizing the meshing and rotation of the external gear 13 with the gear ring 8, so that the handle 1 can rotate on the vertical frame 9.

[0027] Furthermore, the gear ring 8 is fixedly connected to the handle 1, and the gear ring 8 is meshed with the external gear 13. The handle 1 is rotatably connected to the arc-shaped opening 6 through the gear ring 8, so that the grip sleeve 3 on the handle 1 can rotate on the vertical frame 9, so that the arc plate 4 can wipe and clean the surface of the rotating grip sleeve 3 in sequence, thereby cleaning the residual grease and sweat on the grip sleeve 3.

[0028] Furthermore, a towel piece is fixedly connected to the top of the curved plate 4. The curved plate 4 is slidably connected to the vertical frame 9 through the linear guide rail 5. The curved plate 4 is attached to the bottom of the grip 3 through the vertical frame 9, so that the sweat and oil remaining on the grip 3 can be cleaned in time by the attached towel piece, thereby reducing the oil and sweat residue on the dumbbell handle 1.

[0029] Furthermore, a sweat-absorbing pad 10 is embedded at the bottom of the vertical frame 9. The function of the sweat-absorbing pad 10 is to catch and absorb the sweat dripping from the trainee's hands when placing the dumbbells after use, so as to reduce the amount of sweat dripping onto the electronic scale 11.

[0030] Furthermore, side base plates 12 are fixedly connected to both sides of the electronic scale 11. The function of the side base plates 12 is to increase the contact area between the two sides of the vertical frame 9 and the plane on which it is placed, thereby reducing the probability of the electronic scale 11 and the dumbbells placed on the electronic scale 11 tipping over when loading and unloading the dumbbell plates 2, thus increasing the stability of this protection component.

[0031] The usage method of this embodiment is as follows: When using the training dumbbell with the protective component, the protective component needs to be connected to an external power source first. Then, the dumbbell can be placed in the arc-shaped opening 6 at the top of the vertical frame 9 through the gear ring 8 on the handle 1. At this time, the gear ring 8 will mesh with the external gear 13 in the arc-shaped opening 6. Next, the half-clamp ring can be engaged with the slot on the arc-shaped opening 6 to close the top of the arc-shaped opening 6. Then, dumbbell plates 2 of different weights at both ends of the handle 1 can be loaded and unloaded. During the loading and unloading of dumbbell plates 2, the weight of all structures above the vertical frame 9 will be weighed by the electronic scale 11. Since the value displayed by the electronic scale 11 is the value after subtracting the weight of the vertical frame 9 and the original structure on the vertical frame 9, that is... After removing the weight of the vertical frame (9 cents), the actual weight of the dumbbells can be determined by checking the value displayed on the electronic instrument on the front of the scale 11. This allows trainees to easily add or remove weight from the dumbbells on the handle 1. After using the dumbbells, they can be placed on the arc-shaped opening 6, but it is essential to ensure that the external gear 13 is engaged with the gear ring 8. Then, the rotary motor 15 can be started to drive the external gear 13 to engage with the gear ring 8 and rotate, causing the handle 1 to rotate within the arc-shaped opening 6. Simultaneously, the linear guide rail 5 will move the arc plate 4 upward via the slider 14, allowing the towel on the top surface of the arc plate 4 to adhere to the bottom of the grip sleeve 3, enabling the timely wiping and cleaning of any residual oil and sweat on the surface of the grip sleeve 3.

[0032] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
