Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a foldable damping fitness device for physical training. Background Technology

[0002] Hand grippers, as a simple, easy-to-use, and widely applicable fitness equipment, have extensive applications in the fitness field. Whether in home workouts, gym training, or professional athlete training, hand grippers play an irreplaceable role. The working principle of a hand gripper is based on the damping principle; when the hand exerts force to bring the two handles closer together, it needs to overcome the resistance generated by a spring (or damping element). This process of overcoming resistance is the process of training hand muscles. Through repeated training, the strength and endurance of hand muscles can be enhanced, and the dexterity and coordination of fingers can be improved. However, a common problem with existing hand grippers is that the handles cannot be folded, making them inconvenient for users to carry and store.

[0003] A Chinese patent document with authorization announcement number CN219128199U discloses a foldable hand gripper, including a screw-in stainless steel handle, a folding handle structure, and a strip groove. By setting a folding handle structure, the screw-in stainless steel handle is modified so that the handle can be unfolded from a folded state when needed. After unfolding, the handle length is extended. The handle length can be extended by unfolding the folded handle, and the strength of the hand gripper can be changed by gripping different positions of the handle, making it more convenient to use.

[0004] In use, the aforementioned patent allows the extended handle to unfold from its folded state by rotating it out of the groove. However, the extended handle lacks a locking mechanism to fix its position during folding and unfolding, failing to consider that the handle might be accidentally folded or unfolded during training, potentially causing the user to lose balance or suffer accidental injury due to sudden changes in hand force. Utility Model Content

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] See Figures 1 to 6 As shown, this utility model provides a foldable damping fitness device for physical training, including a grip frame 1, a first grip handle 2 at the bottom of the grip frame 1, a grip block 3 rotatably mounted on one side of the grip frame 1, a movable block 4 movably mounted on the grip block 3, a driving component for driving the movable block 4 to move inside the grip block 3, a hook spring 5 mounted on the movable block 4, one end of the hook spring 5 being connected to the top of the grip frame 1, a second grip handle 6 at the bottom of the grip block 3, and extension components 7 in both the first grip handle 2 and the second grip handle 6. The extension components 7 include an extension handle 71 that can extend from inside the first grip handle 2 and the second grip handle 6, and a fixing component for fixing the position of the extension handle 71.

[0024] Users train by gripping the first grip handle 2 and the second grip handle 6. When the length of the first grip handle 2 and the second grip handle 6 needs to be adjusted according to the user's needs, an extension handle 71 is extended from inside the first grip handle 2 and the second grip handle 6, and the position of the extension handle 71 is locked by a fixing component to prevent the extension handle 71 from accidentally folding during training.

[0025] When the user pushes the grip block 3, the hook spring 5 is stretched along with the moving block 4, generating a tensile force, i.e., a damping effect. This damping effect provides resistance to the user during training, requiring the user to overcome the resistance to complete the pushing motion, thereby training the strength of the upper limbs, shoulders, and core muscles.

[0026] In addition, the driving component can drive the moving block 4 to move, thereby driving the hook spring 5 to stretch, thereby changing the tension of the hook spring 5 to adapt to different training needs.

[0027] See Figures 1 to 4 As shown, the extension component 7 also includes a rotating shaft 72; both the first grip handle 2 and the second grip handle 6 are provided with receiving grooves, the rotating shaft 72 is horizontally arranged inside the rotating shaft 72, and the extension handle 71 is rotatably arranged on the rotating shaft 72.

[0028] When the length of the first grip handle 2 and the second grip handle 6 needs to be adjusted according to the user's needs, the user can rotate the extension handle 71 out of the receiving slots of the first grip handle 2 and the second grip handle 6. The position of the extension handle 71 is fixed by a fixing component, so that the user can adjust it according to their height and arm length to adapt to different training needs.

[0029] See Figure 3As shown, the fixing component includes a smooth rod 73; both sides of the first grip handle 2 and the second grip handle 6 have mounting grooves. The smooth rod 73 has two parts and is horizontally set in the mounting grooves. One end of the smooth rod 73 is provided with a limiting plate 74. A sliding block 75 is slidably arranged on the smooth rod 73. A first spring 76 is also sleeved on the smooth rod 73. One end of the first spring 76 abuts against one side of the limiting plate 74, and the other end of the first spring 76 abuts against one side of the sliding block 75. One end of the sliding block 75 is provided with a pull plate 77. One side of the pull plate 77 is provided with an insertion rod 78. One end of the insertion rod 78 is provided with an abutment part. The extension handle 71 is provided with an insertion groove 710 that can be inserted and cooperated with the abutment part. The pull plate 77 is provided with a pull handle 79 on the side away from the insertion rod 78.

[0030] When the user needs to adjust the length of the first grip handle 2 and the second grip handle 6, they first grasp the handle 79 and pull it outwards. The handle 79 drives the pull plate 77 to move, and the pull plate 77 drives the sliding blocks 75 on both sides to slide on the smooth rod 73, while compressing the first spring 76. At this time, the abutting part of the insertion rod 78 disengages from the insertion slot 710 of the extension handle 71, allowing the extension handle 71 to rotate out of the receiving slots of the first grip handle 2 and the second grip handle 6. After the adjustment is completed, the user releases the handle 79. Under the restoring force of the first spring 76, the sliding block 75 drives the pull plate 77 and the insertion rod 78 to move towards the limiting plate 74 until the abutting part of the insertion rod 78 re-inserts into the insertion slot 710 of the extension handle 71, thereby fixing the extension handle 71 and ensuring that the extension handle 71 will not be accidentally folded during training.

[0031] See Figure 5 and Figure 6 As shown, the driving component includes a threaded rod 41; a rectangular groove is provided on the gripping block 3, the threaded rod 41 is horizontally arranged in the rectangular groove, one end of the threaded rod 41 extends through the rectangular groove to one side of the gripping block 3, a knob 42 is provided at the extended end of the threaded rod 41, and a movable block 4 is provided on the threaded rod 41 that can move along the threaded rod 41.

[0032] The user rotates knob 42, which in turn rotates threaded rod 41 within a rectangular groove. Since moving block 4 and threaded rod 41 are threaded together, moving block 4 moves along the axis of threaded rod 41 as threaded rod 41 rotates. This movement of moving block 4 stretches or compresses hook spring 5, thereby changing the tension of hook spring 5 and adjusting the damping effect to meet the training needs and fitness levels of different groups.

[0033] See Figure 1 As shown, a slide bar 43 is horizontally arranged at the bottom of the threaded rod 41 inside the rectangular groove, and the moving block 4 is slidably arranged on the slide bar 43.

[0034] When the user rotates the knob 42 to move the moving block 4 along the axis of the threaded rod 41, the moving block 4 will slide on the slide bar 43, further ensuring the stability and accuracy of the moving block 4.

[0035] See Figure 1 As shown, the second grip handle 6 has a grip groove that can enhance the grip friction of the user.

[0036] By providing grip grooves on the second grip handle 6, the surface texture of the second grip handle 6 is increased, thereby increasing the contact area between the user's hand and the second grip handle 6, allowing the user's hand to fit more tightly on the second grip handle 6, preventing slippage and loss of control.

[0037] Users train by gripping the first grip handle 2 and the second grip handle 6. When the length of the first grip handle 2 and the second grip handle 6 needs to be adjusted according to the user's needs, the user first grasps the pull handle 79 and pulls it outward. The pull handle 79 drives the pull plate 77 to move, and the pull plate 77 drives the sliding blocks 75 on both sides to slide on the smooth rod 73, while compressing the first spring 76. At this time, the abutting part of the insertion rod 78 disengages from the insertion slot 710 of the extension handle 71, allowing the extension handle 71 to rotate out of the receiving slots of the first grip handle 2 and the second grip handle 6. After the adjustment is completed, the user releases the pull handle 79. Under the restoring force of the first spring 76, the sliding block 75 drives the pull plate 77 and the insertion rod 78 to move towards the limiting plate 74 until the abutting part of the insertion rod 78 re-inserts into the insertion slot 710 of the extension handle 71, thereby fixing the extension handle 71 and ensuring that the extension handle 71 will not be accidentally folded during training. When the user pushes the gripping block 3, the hook spring 5 is stretched along with the moving block 4, generating a tensile force, i.e., a damping effect. This damping effect provides resistance during training, requiring the user to overcome this resistance to complete the pushing motion, thereby training the strength of the upper limbs, shoulders, and core muscles. Furthermore, the drive mechanism can move the moving block 4, which in turn stretches the hook spring 5, changing its tension to adapt to different training needs.

[0038] The above embodiments only illustrate one or more implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
