Abstract
Description
Technical Field
[0001] This utility model belongs to the field of arm strength training technology, and in particular relates to an arm strength training device. Background Technology
[0002] Arm strength training is a common activity in physical fitness training. It increases arm strength, enabling you to lift and retrieve heavier objects. Arm strength training not only improves endurance under load but also enhances the arm's load-bearing capacity.
[0003] Most current arm strength training methods involve lifting barbells with the arms. However, this method has a drawback: for beginners, the barbell often falls and injures them when they lift it overhead because their arms cannot bear the weight.
[0004] Therefore, in actual training, the barbell should not be raised above the head. However, because the barbell is constantly raised and lowered during training, the load on the waist is relatively large, which increases fatigue and makes the improvement of arm strength inefficient.
[0005] At the same time, after training for a period of time, the weight is often increased by adding weight plates to the barbell. However, when the arm strength limit is reached, the weight of the weight plates cannot be gradually increased (the weight plates are standard weight iron plates, such as 5kg or 10kg). Therefore, if an extra weight plate is added during training, the trainee's arm strength may not be able to keep up, causing the barbell to fall. In severe cases, it can easily lead to muscle strain.
[0006] Therefore, in actual exercise, the method of adding a weight plate is not only easy to injure the exerciser, but also very easy to cause muscle strain.
[0007] Therefore, during arm strength training, a method that can both protect the lower back and appropriately increase the load of lifting the barbell according to the trainee's arm strength can not only enhance the training effect but also protect the trainee. Utility Model Content
[0008] Based on the above background, the purpose of this utility model is to provide an arm strength training device.
[0009] To achieve the above objectives, the present invention adopts the following technical solution:
[0010] An arm strength training device includes a support mechanism, on the top of which is fitted with an arm strength training structure spaced apart on both sides. The arm strength training structure includes an arm strength lifting rod, and a gravity plate is installed at each end of the arm strength lifting rod.
[0011] The arm-lifting rod is elastically and slidably connected by several spring support structures;
[0012] The arm strength training device also includes a resistance-increasing structure that increases the height of the gravity plate. The resistance-increasing structure includes resistance bars clamped on both sides of the gravity plate, and several elastic protrusions that abut against the side wall of the gravity plate are fixedly connected to the resistance bars.
[0013] The upper and lower ends of the resistance bar are respectively adjusted by screw locking components to control the clamping force of the gravity plate;
[0014] The resistance-increasing structure also includes a mounting bracket fixedly installed on the support mechanism, and the mounting bracket is fixedly installed on the screw locking member.
[0015] Preferably, the support mechanism includes support portions spaced apart on the left and right sides, with a connecting portion integrally formed between the support portions, and the support mechanism also includes a U-shaped frame fixedly connected between the two support portions.
[0016] Preferably, a pair of spring-assisted lifting arm structures are fixedly connected to the bottom of the U-shaped frame.
[0017] Preferably, the spring-assisted lifting arm structure includes a lifting arm spring fixedly connected to the U-shaped frame, and a sleeve ring is fixedly connected to the lifting arm spring.
[0018] Preferably, the front and rear ends of the arm-lifting rod are slidably connected by a pair of spring bracket structures;
[0019] The spring bracket structure includes a spring bracket fixedly installed on the support portion. The spring bracket has a sliding opening. An inner sliding rod that is slidably connected to the arm lifting rod is fixedly connected inside the sliding opening. A reinforcing spring is sleeved on the inner sliding rod. The two ends of the reinforcing spring are respectively fixedly connected to the bottom of the arm lifting rod and the bottom position inside the sliding opening.
[0020] Preferably, the mounting bracket is fixedly mounted on the screw locking member located at the lower end.
[0021] Preferably, the screw locking member includes a horizontal screw that is slidably connected between the resistance bars;
[0022] Both ends of the horizontal screw are threadedly connected to push nuts positioned on the resistance bar;
[0023] The mounting bracket is fixedly connected to a horizontal screw located at the lower end.
[0024] Preferably, the elastic protrusion is made of rubber.
[0025] Preferably, the gravity disk is slidably connected to the arm lifting rod;
[0026] The end of the arm lifting rod is threadedly connected to a nut that locks the gravity plate;
[0027] The arm-lifting rod has an integrally formed annular flange with a gravity plate.
[0028] This utility model has the following beneficial effects:
[0029] 1. The training process does not require excessive bending over, thus protecting the lower back. It also allows for repeated arm strength training using a bar and gravity plate, thereby improving arm strength. Because the lower back is not involved in the training, trainees can maintain arm strength training for extended periods without experiencing lower back fatigue, greatly increasing training efficiency.
[0030] 2. To increase the "weight sensation" when lifting the weight plate during training and enhance training intensity, the resistance bars on both sides are brought closer together until the elastic protrusions contact the side wall of the weight plate. The contact force is adjusted according to the depth of the tightening of the push nut. With the elastic protrusions in contact, the friction force increases as the weight plate is lifted, requiring greater arm strength. Therefore, this method eliminates the need for adding a weight plate during training. By adjusting the tightness of the elastic protrusions' contact according to the operator's arm strength tolerance, the magnitude of the frictional resistance is adjusted, allowing for a gradual increase in frictional resistance (through adjusting the push nut) to progressively strengthen the arm, thus achieving scientific training while protecting the trainee.

[0041] Example 1
[0042] like Figure 1-5 As shown, an arm strength training device includes a support mechanism 1. The specific structure of the support mechanism 1 is as follows: the support mechanism includes support portions 11 spaced apart on the left and right sides, and a connecting portion 12 integrally formed between the support portions 11. The support mechanism also includes a U-shaped frame 13 fixedly connected between the support portions 11 on both sides.
[0043] An arm strength training structure (the arm strength training structure is installed on the support part) is assembled and connected on the top of the support mechanism with spaced-apart arm strength training structures on both sides. The arm strength training structure includes an arm strength lifting rod 21, and a gravity plate 22 is installed at both ends of the arm strength lifting rod 21.
[0044] The specific method is as follows: the gravity plate 22 is detachable and installed in the following way: the gravity plate 22 is slidably connected to the lifting arm 21; the end of the lifting arm 21 is threaded with a nut to lock the gravity plate 22; an annular flange is integrally formed on the lifting arm 21 to separate the gravity plate 22 (the gravity plate 22 is separated between the nut and the annular flange). This method allows the gravity plate 22 to be detachable and installed, making it easy to replace gravity plates 22 of different weights.
[0045] Meanwhile, the arm-lifting rod 21 is elastically and slidably connected by several spring bracket structures 3; specifically, the front and rear ends of the arm-lifting rod 21 are slidably connected by a pair of spring bracket structures 3 respectively.
[0046] The spring bracket structure 3 includes a spring bracket 33 fixedly installed on the support part 11. The spring bracket 33 has a sliding opening. An inner sliding rod 31 that is slidably connected to the arm lifting rod 21 is fixedly connected in the sliding opening (the top of the inner sliding rod 31 is higher than the sliding opening and a partition seat is installed on the top). A reinforcing spring 33 is sleeved on the inner sliding rod 31. The two ends of the reinforcing spring 33 are respectively fixedly connected to the bottom of the arm lifting rod 21 and the bottom position inside the sliding opening.
[0047] Under normal circumstances, the height of the arm-lifting bar 21-gravity plate 22 corresponds to the operator's hand position (i.e., the spring bracket 33 has a certain height; under normal circumstances, the reinforcing spring 33 is in a compressed state, at which time the height of the arm-lifting bar 21 is close to the operator's hand position). During the exercise, the operator grips the arm-lifting bar 21 with both hands and raises the arm-lifting bar 21-gravity plate 22 structure upwards, then quickly lowers it, repeating this process to exercise arm strength.
[0048] In order to assist the operator in raising the heavy lifting arm 21-gravity plate 22 during this process, a pair of spring-assisted lifting arm structures are fixedly connected to the bottom of the U-shaped frame 13. The spring-assisted lifting arm structure includes a lifting arm spring 51 fixedly connected to the U-shaped frame 13, and an arm loop 52 (the arm loop 52 is fitted onto the operator's arm or forearm) is fixedly connected to the lifting arm spring 51.
[0049] When the operator grips the lifting lever 21 with their hand, the lifting spring 51 stretches. Then, as the operator raises the lifting lever 21 to the gravity plate 22, the lifting spring 51 provides assisted lifting under its elastic restoring force.
[0050] This method not only eliminates the need for excessive bending during training, thus protecting the lower back, but also allows for repeated lifting of the arm lever 21 and gravity plate 22 for arm strength training. Because the lower back is used less, trainees can maintain arm strength training for extended periods without experiencing lower back fatigue, greatly increasing training efficiency.
[0051] Example 2
[0052] like Figure 1-5 As shown, based on the structure of Embodiment 1, the above-mentioned arm strength training device further includes a resistance-increasing structure that raises the gravity disk 22. The resistance-increasing structure includes resistance bars 43 clamped on both sides of the gravity disk 22. Several elastic protrusions 431 (rubber material) that abut against the side wall of the gravity disk 22 are fixedly connected to the resistance bars 43.
[0053] Meanwhile, the upper and lower ends of the resistance bar 43 adjust the clamping force of the gravity plate 22 via screw locking components. The aforementioned resistance-enhancing structure also includes a mounting bracket 41 fixedly installed on the support mechanism, which is fixedly installed on the screw locking component located at the lower end.
[0054] The specific structure of the screw locking component is as follows:
[0055] The screw locking component includes a horizontal screw 42 that is slidably connected between the resistance bars 43; push nuts 421 that are positioned on the resistance bars 43 are threaded to both ends of the horizontal screw 42; and a mounting bracket 41 is fixedly connected to the horizontal screw 42 located at the lower end.
[0056] During operation, to increase the "weight" sensation when the weight plate 22 is lifted and enhance training intensity, the resistance bars 43 on both sides are brought closer together until the elastic protrusions 431 contact the side wall of the weight plate 22. The contact force is adjusted according to the depth of the tightening of the push nut 421 (the greater the deformation of the elastic protrusions 431, the greater the friction). Under the contact of the elastic protrusions 431, the friction force of lifting the weight plate 22 increases, thus requiring greater arm strength. Therefore, this method eliminates the need to add a weight plate during training. By adjusting the tightness of the contact of the elastic protrusions 431 according to the operator's arm strength tolerance, the magnitude of the frictional resistance is adjusted, thereby gradually increasing the frictional resistance (by adjusting the push nut 421) to achieve progressive arm strength training, thus achieving scientific training while protecting the trainee.
[0057] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
