Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of fitness equipment, and in particular to a deadlifter. Background Technology
[0002] The deadlift is a highly practical exercise in the fitness industry. It effectively enhances muscle strength, improves body stability, promotes fat burning, improves posture, increases bone density, and boosts athletic performance. During a deadlift, almost all muscles in the body are involved, particularly the arms, scapulae, back muscles, and glutes.
[0003] However, currently, deadlifts on the market are only performed with a regular barbell. But barbell deadlifts place certain demands on the exerciser; beginners or those without relevant experience find them very difficult and are prone to injury. The main reason is that in traditional barbell deadlifts, the body is positioned behind the barbell. When the body pulls the barbell up, the lumbar spine bears enormous pressure. If there is any improper movement (abnormal form or failure to engage the core), the lower back is very susceptible to injury. Secondly, in traditional barbell deadlifts, the barbell needs to be kept in close contact with the exerciser's legs and hips, which generates a lot of friction, easily causing leg swelling, redness, and skin abrasions. Long-term practice of traditional barbell deadlifts can also inhibit leg hair growth and cause hair loss. Utility Model Content
[0004] Therefore, it is necessary to provide a hard puller to solve the above-mentioned technical problems.
[0005] A deadlifter, the deadlifter comprising:
[0006] The support frame includes a first bell support arm and two second bell support arms. One end of each of the two second bell support arms is connected to both ends of the first bell support arm. The second bell support arms are inclined and symmetrically arranged relative to the first bell support arm. The first bell support arm and the two second bell support arms are on the same plane.
[0007] The first bell assembly is provided on each of the second bell support arms, and the first bell assembly is disposed at the other end of the second bell support arm.
[0008] Optionally, an inclined angle is formed between the connection points of the first bell support arm and the second bell support arm, wherein the angle is greater than or equal to 90 degrees and less than 180 degrees.
[0009] Optionally, the first bell support arm includes a first main body and a first support, two second bell support arms are respectively disposed at both ends of the first main body, and the first support is vertically disposed in the middle of the first main body.
[0010] Optionally, the second bell support arm includes a second main body and a second support. One end of the second main body is inclinedly disposed on the first main body, and the other end of the second main body is connected to the second support. The axial direction of the second support is parallel to the axial direction of the first main body, and the first bell assembly is disposed on the second support.
[0011] Optionally, a second bell assembly is also included, which is disposed on the first support portion.
[0012] Optionally, the first bell assembly and the second bell assembly have the same structure.
[0013] Optionally, the first weight plate assembly includes a barbell plate and a limiting component. The barbell plate is sleeved on the second support portion, and the limiting component is disposed on the second support portion. The limiting component is used to limit and fix the barbell plate.
[0014] Optionally, the limiting component includes a limiting member and a barbell lock.

[0025] refer to Figures 1 to 3This application provides a deadbolt, which includes a support frame 1 and a first bell assembly 2. The support frame 1 includes a first bell support arm 11 and two second bell support arms 12. One end of each of the two second bell support arms 12 is connected to both ends of the first bell support arm 11. The second bell support arms 12 are inclined and symmetrically arranged relative to the first bell support arm 11. The first bell support arm 11 and the two second bell support arms 12 are on the same plane. Each second bell support arm 12 is provided with a first bell assembly 2, which is located at the other end of the first bell support arm of the second bell support arm 12.
[0026] This application provides a deadlift machine. By symmetrically arranging two second weight plate support arms 12 at both ends of a first weight plate support arm 11, and with the second weight plate support arms 12 inclined relative to the first weight plate support arm 11, the human body is positioned at the geometric center of the deadlift machine during exercise. Compared to the prior art, where the human body is positioned behind the barbell and the lower back bears enormous pressure, making it difficult to exert force, the deadlift machine of this application positions the human body at the geometric center of the deadlift machine during exercise. During the exertion process, all muscles of the body exert force evenly, and there is no local pressure caused by the concentration of force in a certain part. Furthermore, the human body maintains a certain safe distance from the deadlift machine, so even if the operation is improper, there will be no injury.
[0027] refer to Figure 1 and Figure 2 The first bell support arm 11 includes a first main body 13 and a first support 14. Two second bell support arms 12 are respectively disposed at both ends of the first main body 13, and the first support 14 is vertically disposed in the middle of the first main body 13.
[0028] Specifically, the first main body 13 is horizontally positioned, and the first support 14 is positioned on the side of the first main body 13 away from the second bell support arm 12, so as to avoid the first support 14 interfering with human exercise.
[0029] refer to Figures 1-2 The second weight plate support arm 12 includes a second main body 15 and a second support 16. One end of the second main body 15 is inclinedly disposed on the first main body 13, and the other end of the second main body 15 is connected to the second support 16. The axial direction of the second support 16 is parallel to the axial direction of the first main body 13. The first weight plate assembly 2 is disposed on the second support 16. In this embodiment, the distance between the second support 16 and the first main body 13 is designed to be greater than the thickness of the exerciser's body so that the exerciser can be located at the geometric center of the deadlift machine. Specifically, the distance between the second support 16 and the first main body 13 is greater than 20 centimeters.
[0030] By providing a second support portion 16 at the end of the second main body portion 15 away from the first main body portion 13, and by providing the second support portion 16 horizontally, and by providing the first bell plate assembly 2 on the second support portion 16, it is possible to make the exerciser exert force more evenly during exercise, and also to increase the distance between the first bell plate assembly 2 and the human body, thereby further improving safety.
[0031] In this embodiment, the length of the second main body 15 is greater than the length of the first main body 13.
[0032] refer to Figures 1-2 An inclined angle is formed between the connection of the first bell support arm 11 and the second bell support arm 12, and the angle of the inclined angle is greater than or equal to 90 degrees and less than 180 degrees.
[0033] Specifically, there is an inclined angle between the axis of the first main body 13 and the axis of the second main body 15.
[0034] Preferably, the angle of inclination is greater than or equal to 90 degrees and less than or equal to 150 degrees. In this embodiment, the support frame 1 is trapezoidal, specifically, the angle of inclination is equal to 135 degrees.
[0035] refer to Figure 1 and Figure 3 The deadlifter also includes a second weight plate assembly 3, which is disposed on the first support portion 14. By incorporating the second weight plate assembly 3, the overall training effect of various parts of the body can be improved during exercise.
[0036] Specifically, the first bell assembly 2 is located at one end of the second support portion 16 near the second main body portion 15, and the second bell assembly 3 is located at one end of the first support portion 14 near the first main body portion 13.
[0037] refer to Figures 1 to 3 The first bell assembly 2 and the second bell assembly 3 have the same structure.
[0038] The first weight plate assembly 2 and the second weight plate assembly 3 respectively include a barbell plate 21 and a limiting component 22. The barbell plate 21 is sleeved on the second support part 16, and the limiting component 22 is disposed on the second support part 16. The limiting component 22 is used to limit and fix the barbell plate 21.
[0039] The barbell plates 21 and the limiting components 22 of the second barbell plate assembly 3 are both located on the first support part 14.
[0040] Specifically, the number of barbell plates 21 is at least one. In actual use, the number of barbell plates 21 can be increased or decreased to adapt to different training needs. In other embodiments, the barbell plates can be dumbbell plates.
[0041] refer to Figure 3The limiting component 22 includes a limiting member 23 and a bell lock 24. The limiting member 23 and the bell lock 24 are sleeved on the second support part 16. The barbell plate 21 is disposed between the limiting member 23 and the bell lock 24. The limiting member 23 and the bell lock 24 cooperate to achieve the limiting and fixing of the barbell plate 21.
[0042] The limiting member 23 and the bell lock 24 of the second bell assembly 3 are sleeved on the first support part 14.
[0043] Specifically, the support frame 1 is integrally formed, and the limiting member 23 is integrally formed with the support frame 1. By having the limiting member 23 abut against one side of the barbell plate 21 and the plate lock 24 abut against the other side of the barbell plate 21, the barbell plate 21 can be prevented from slipping off the first support part 14 or the second support part 16.
[0044] During exercise, the exerciser is positioned at the geometric center of the deadlift machine, maintaining a certain spatial distance from it at all times, and gripping the second main body part 15, resulting in a very even distribution of force. No single part of the body bears excessive pressure, and the legs do not need to be in close contact with the machine, preventing injury to the leg skin. In short, this deadlift machine is safer, more convenient, and more efficient to operate.
[0045] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
