Description

Adjustable hand grip training handle frame Technical Field

[0001] This application relates to the technical field of fitness equipment, and in particular to a training handle frame with adjustable hand grip position. Background Technology

[0002] The barbell is an indispensable core piece of equipment in weightlifting training. It not only helps to increase muscle strength but also improves overall body coordination through a variety of training movements. Traditional barbells have a relatively simple construction, consisting of a long metal bar and weight plates at both ends. Users need to grip the middle of this metal bar to perform various exercises. However, this design is not flexible enough when performing specific exercises such as the bench press, because the fixed grip position makes it difficult to adapt to the needs of different users or provide a comfortable grip angle.

[0003] The existing technology discloses a modified barbell bar specifically designed for bench press, patent number "CN217287042U". This technology replaces the traditional one-piece metal bar with a mounting bracket featuring multiple hand grips, which is then fitted between two sets of weight plates. This provides more grip options, increasing flexibility. However, this method also has limitations: the positions of these hand grips are fixed, and their number is limited, thus failing to fully meet the requirements for personalized adjustments based on individual training needs and physical conditions.

[0004] Therefore, those skilled in the art have provided training handle frames with adjustable hand grip positions to address the problems mentioned in the background art. Summary of the Invention

[0005] To address the problems mentioned in the background art, this application provides a training handle frame with adjustable hand grip position.

[0006] The adjustable hand grip training handle frame provided in this application adopts the following technical solution: it includes an adjustment box, on both sides of the adjustment box a barbell bar is slidably connected, each barbell bar is fixedly connected to a connecting plate at one end of the adjustment box, a rack is fixedly connected to the bottom of the connecting plate, a gear is meshed on the outer surface of the rack, a rotating rod is fixedly connected inside the gear and rotatably connected to the inner wall of the adjustment box, and a fixing mechanism is connected to one end of the rotating rod that passes through the adjustment box, the fixing mechanism being used to fix the rotating rod.

[0007] Preferably, the upper and lower inner walls of the regulating box are provided with tracks that match the size of the rack.

[0008] Preferably, the fixing mechanism includes a threaded rod and a nut, the outer surface of the threaded rod is threadedly connected to the inner thread of the rotating rod, and the outer surface of the threaded rod is threadedly connected to a nut that is fixedly installed inside the adjusting box.

[0009] Preferably, a second rotating cap is fixedly connected to one end of the threaded rod.

[0010] Preferably, a first rotating cap is fixedly connected to one end of the rotating rod that passes through the adjusting box.

[0011] In summary, this application includes the following beneficial technical effects:

[0012] By rotating the second nut, the nut is disengaged from the inside of the rotating rod, releasing the gear. Then, the barbell rod is pulled, which drives the rack through the connecting plate. The rack moves, which in turn drives another rack through the gear. The other rack then pushes the other end of the barbell rod through the connecting plate, thus completing the adjustment of the length of the barbell rods at both ends. Attached Figure Description

[0017] The technical solution of this utility model will now be clearly and completely described with reference to Figures 1-3. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] This application discloses an adjustable hand grip training handle frame, referring to Figures 1-3. It includes an adjustment box 2, with barbell bars 1 slidably connected to both sides of the adjustment box 2. Each barbell bar 1 is fixedly connected to a connecting plate 5 at one end of the adjustment box 2. A rack 4 is fixedly connected to the bottom of the connecting plate 5. The upper and lower inner walls of the adjustment box 2 are provided with tracks 3 matching the size of the rack 4, providing a sliding path for the rack 4. A gear 6 meshes with the outer surface of the rack 4. A rotating rod 7, rotatably connected to the inner wall of the adjustment box 2, is fixedly connected inside the gear 6. A first rotating cap 8 is fixedly connected to one end of the rotating rod 7 passing through the adjustment box 2, and a fixing mechanism is connected to the other end of the rotating rod 7 passing through the adjustment box 2. By using the rack 4, connecting plate 5, gear 6, rotating rod 7, and fixing mechanism in combination, the position of the barbell bars 1 at both ends of the adjustment box 2 can be quickly adjusted.

[0019] In this application, the fixing mechanism includes a threaded rod 9 and a nut 10. A second rotating cap 11 is fixedly connected to one end of the threaded rod 9, which facilitates manual rotation of the threaded rod 9. The outer surface of the threaded rod 9 is threadedly connected to the inner thread of the rotating rod 7. The outer surface of the threaded rod 9 is threadedly connected to a nut 10 that is fixedly installed inside the adjusting box 2. By setting the threaded rod 9, nut 10 and second rotating cap 11 to work together, the effect of quickly fixing the rotating rod 7 can be achieved.

[0020] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0021] The implementation principle of the adjustable hand grip training handle frame in this application embodiment is as follows: In use, rotating the second rotating cap 11 causes the nut 10 to disengage from the inside of the rotating rod 7, releasing the fixation of the gear 6. Then, pulling the barbell rod 1 drives the rack 4 to move through the connecting plate 5. The movement of the rack 4 drives another rack 4 to move through the gear 6. The other rack 4 pushes the other end of the barbell rod 1 to move through the connecting plate 5, thus completing the adjustment of the length of the barbell rods 1 at both ends. Then, rotating the second rotating cap 11 drives the threaded rod 9 to rotate. The threaded rod 9 rotates to be threadedly connected to the rotating rod 7 and fixes the rotating rod 7, thereby fixing the gear 6 and completing the adjustment of the length of the barbell rods 1 at both ends.
