Technical Field
[0001] This utility model relates to the field of fitness equipment technology, specifically to an arm strength trainer. Background Technology
[0002] Arm strength trainers, also known as grip strengtheners, are used to exercise the arm muscles, primarily targeting arm and chest muscles, and supplementing wrist strength. Currently, arm strength training equipment on the market generally suffers from the following problems: First, their fixed structure prevents adjustment of training intensity based on the user's strength level, limiting training effectiveness; second, most devices use a one-piece design, making them inconvenient to carry and store; and third, traditional arm strength trainers employ a single force application method, failing to fully utilize the lever principle to achieve effort-saving or force-increasing effects, thus impacting training efficiency.
[0003] While some arm strength trainers in the current technology use elastic elements to provide resistance, they typically lack convenient adjustment mechanisms, making it difficult for users to quickly adjust the pulling force. Furthermore, the fulcrum structure of these devices is mostly fixed, making it impossible to change the leverage ratio to adapt to different training needs. In terms of disassembly, most products require tools to assemble or disassemble, making them inconvenient to use.
[0004] Therefore, there is an urgent need for an arm strength training device based on the lever principle, with adjustable tension and easy disassembly, to solve the above-mentioned problems in the existing technology and meet the diverse training needs of users. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides an arm strength trainer that features advantages such as easy adjustment of pulling force, convenient use of the arc-shaped grip, lever principle for effort-saving or force-increasing, and quick disassembly for easy carrying. It solves the problems of limited pulling training effect, inconvenience in carrying and storing, and the single force application mode of arm strength trainers.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an arm strength device, including a left handle and a right handle, wherein a push rod is fixedly installed on both top corners of the left handle and the right handle, and a pressure rod is fixedly installed on both bottom corners of the left handle and the right handle; a connecting shaft for connecting the left handle and the right handle is provided at the intersection of the bottom of the left handle and the right handle.
[0007] The top of both the left and right handles is provided with elastic element placement slots. One or more elastic elements that apply tension are arranged between the two elastic element placement slots. The left and right handles rotate around the connecting shaft, so that the push rod, the pressure rod, and the elastic element placement slots form a lever structure with the connecting shaft as the fulcrum.
[0008] Furthermore, the arc-shaped rod of the pressure rod can be greatly adapted to the force exerted by the user's arm.
[0009] Furthermore, the elastic element consists of two anti-slip buckles and an elastic band between the two anti-slip buckles, with the two anti-slip buckles respectively disposed inside the elastic element placement slots opened on the left handle and the right handle.
[0010] Furthermore, the side of the elastic element placement groove near the elastic element is provided with anti-slip texture to enhance friction with the elastic element.
[0011] Furthermore, the connecting shaft consists of two axle wheels and a central pin. The two axle wheels of the connecting shaft are respectively fixed to the left handle and the right handle, and the pin passes through the pin hole in the two axle wheels.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] 1. This arm strength trainer uses an arc-shaped pressure bar to facilitate arm grip strength. At the same time, the inward squeezing causes the left and right handles to make arc-shaped lever movements around the connecting shaft, so as to achieve convenience, effort saving or force increase. Different strength training effects can also be achieved by increasing or decreasing the elastic elements inside the elastic element placement slot.
[0014] 2. This arm exerciser allows for quick disassembly of the left and right handles by quickly pulling the pin in the middle of the connecting shaft out of the pin holes of the two axle wheels, making it easy to carry. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-2In this embodiment, an arm strength trainer includes a left handle 1 and a right handle 2. Push rods 4 are fixedly installed on the top corners of both sides of the left handle 1 and the right handle 2. These are support rods used for leg strength training. The two thighs are placed together between the two push rods 4 and pushed outward to achieve the effect of leg strength training. Pressure rods 3 are fixedly installed on the bottom corners of both sides of the left handle 1 and the right handle 2. These are grip rods used for hand strength training. The two hands grip the two pressure rods 3 and exert force to squeeze inward to achieve hand strength training. A connecting shaft 7 for connecting the left handle 1 and the right handle 2 is provided at the intersection of the bottom of the left handle 1 and the right handle 2.
[0020] The top of both the left handle 1 and the right handle 2 is provided with an elastic element placement slot 6 for placing an elastic element 5. Multiple elastic elements 5 that apply tension are arranged between the two elastic element placement slots 6. The left handle 1 and the right handle 2 rotate around the connecting shaft 7, so that the push rod 4, the pressure rod 3, and the elastic element placement slot 6 form a lever structure with the connecting shaft 7 as the fulcrum.
[0021] It should be noted that the inner corner of the elastic element placement groove 6 near the elastic element 5 can be set to an inward tilt angle to further increase the friction between the elastic element 5 and the elastic element placement groove 6. The pressure rod 3 is covered with a non-slip rubber sleeve to increase stability and comfort when gripping with the arm.
[0022] In this embodiment, the arc-shaped rod of the pressure rod 3 can be greatly adapted to the user's arm exertion.
[0023] It should be noted that the arm exerciser is placed in front of the chest, and the user can easily grasp both pressure bars by raising both hands, which also makes it easier for the user to exert force.
[0024] In this embodiment, the elastic element 5 consists of two anti-slip buckles and an elastic band between the two anti-slip buckles. The two anti-slip buckles are respectively set inside the elastic element placement slots 6 opened in the left handle 1 and the right handle 2.
[0025] It should be noted that different strength training effects can be achieved by increasing or decreasing the number of elastic elements 5.
[0026] In this embodiment, the side of the elastic element placement groove 6 near the elastic element 5 is provided with anti-slip texture to enhance friction with the elastic element 5.
[0027] It should be noted that the anti-slip texture on the side of the elastic element placement groove 6 can play a good anti-slip role with the elastic element 5.
[0028] In this embodiment, the connecting shaft 7 consists of two shaft wheels and a middle pin. The two shaft wheels of the connecting shaft (7) are fixed to the left handle 1 and the right handle 2 respectively, and the pin passes through the pin hole in the two shaft wheels.
[0029] It should be noted that the end of the pin is a forked pin cone. By pressing the forked pin cone at the end, the smaller pin cone diameter is made easier to pull the end of the pin out of the pin hole between the two axle wheels.
[0030] The working principle of the above embodiments is as follows:
[0031] When using a hand gripper, first place the elastic element 5 inside the elastic element placement slot 6 on the left handle 1 and the right handle 2. Then, grip the two pressure rods 3 with your arms and apply pressure inward. This causes the left handle 1 and the right handle 2 to split the elastic element 5 inside the elastic element placement slot 6 from the middle under the lever principle, with the connecting shaft 7 as the center, thus achieving the effect of arm training. When leg training is needed, the two push rods 4 can also be used to push outward by clamping the two thighs near the knees to open the elastic element 5 inside the elastic element placement slot 6, thus achieving the effect of leg training.
