Instead, these exemplary embodiments are provided so that the present utility model can be thoroughly and detailedly conveyed to those skilled in the art.

[0018] <First Embodiment>

[0019] Please refer to Figures 1 to 8 , and describe the fitness equipment 100 of the present utility model. As Figure 1 and Figure 2 shown, the present utility model provides a fitness equipment 100, which can be but is not limited to a barbell or a kettlebell. In this embodiment, the fitness equipment 100 is taken as an example of a barbell for description.

[0020] In this embodiment, the fitness equipment 100 includes a rod member 10, conversion devices 30 connected to both ends of the rod member 10, and a counterweight 50 fixedly disposed on the conversion devices 30.

[0021] Wherein, both ends of the rod member 10 include connecting portions 11 located at both ends. The connecting portions 11 are fixedly connected to the conversion devices 30, and a plurality of through limiting holes 111 and a plurality of auxiliary positioning holes 113 are provided on the connecting portions 11.

[0022] The counterweight 50 includes a cross bar 51, and a part of the cross bar 51 is fixedly received in the conversion device 30.

[0023] Please refer to Figures 2 to 5 , the conversion device 30 includes two locking members 31, a rotating shaft 35, and a fastening member 37. One side of the two locking members 31 is rotatably connected through the rotating shaft 35 so as to be relatively opened and closed, and is fixedly connected through the fastening member 37 in the closed state, so that the two locking members 31 form a locking hole 38 and a receiving hole 39 in the closed state. The locking hole 38 and the receiving hole 39 are arranged in a T shape. The locking hole 38 is used to receive the cross bar 51 of the counterweight 50, and the receiving hole 39 is used to receive the connecting portion 11 of the rod member 10.

[0024] In this embodiment, although it is illustrated that one side of the two locking members 31 is rotatably connected through the rotating shaft 35 so as to be relatively opened and closed, in other embodiments, the two locking members 31 may also be rotatably connected through other hinge structures, which is not limited herein.

[0025] Hereinafter, the part related to the connection between the two locking members 31 and the counterweight 50 will be described.

[0026] Specifically, each locking member 31 includes a main body 311 and at least two engaging blocks 313. Two end faces of the main body 311 are recessed to form arc-shaped notches 315. When one side of the two locking members 31 away from the rotating shaft 35 abuts, that is, when the two locking members 31 are in the closed state, the notches 315 of the two locking members 31 together form the locking hole 38 for receiving the counterweight 50.

[0027] Furthermore, at least two receiving grooves 316 are arranged at intervals along the length direction inside the main body 311. The at least two receiving grooves 316 communicate with the notches 315. The at least two engaging blocks 313 are spaced apart and received in the corresponding receiving grooves 316. The at least two engaging blocks 313 are independent components. In this embodiment, the length direction of the main body 311 is the same as the extending direction of the rotating shaft 35.

[0028] In this embodiment, the extending direction of the notch 315 is the same as the arrangement direction of the at least two receiving grooves 316.

[0029] It can be understood that a clamping block 313 is arranged in the receiving groove 316, and a part of the clamping block 313 is exposed to the locking hole 38 through the notch 315. Therefore, when the counterweight 50 is received in the receiving hole 39, a part of the cross bar 51 of the counterweight 50 is in close contact with the part of the clamping block 313 exposed to the locking hole 38, so that the cross bar 51 of the counterweight 50 can be prevented from axially or laterally moving in the locking hole 38, the stability of the fitness equipment 100 is improved, and thus the safety is improved.

[0030] In addition, by setting at least two clamping blocks 313 as independent clamping blocks 313 and arranging them in the corresponding receiving grooves 316, the clamping blocks 313 do not affect each other, and the cross bar 51 of the counterweight 50 can be prevented from sliding or disengaging in the locking hole 38. In addition, the usage amount of the clamping blocks 313 can be effectively reduced, thus effectively reducing the cost.

[0031] Furthermore, a spacing groove 317 is arranged between two adjacent receiving grooves 316 among at least two receiving grooves 316, so that the two adjacent receiving grooves 316 are separated by a specified distance. In this way, a notch 315, a receiving groove 316, the spacing groove 317, another receiving groove 316, and another notch 315 are sequentially communicated to form the locking hole 38. In this embodiment, no clamping block 313 is arranged in the spacing groove 317. It can be understood that the spacing groove 317 and the receiving groove 316 can be arranged alternately, or the positions of the spacing groove 317 and the receiving groove 316 can be adjusted according to requirements.

[0032] Furthermore, the spacing groove 317 and the adjacent receiving groove 316 are separated by a partition plate 318, so that the spacing groove 317 and the receiving groove 316 are both independent grooves. By arranging the partition plate 318 to make the receiving groove 316 an independent groove, and each receiving groove 316 receives a corresponding clamping block 313, the axial movement of the clamping block 313 in the receiving groove 316 can be effectively prevented, the stability of the conversion device 30 can be improved, and thus the safety of the fitness equipment 100 can be improved.

[0033] It can be understood that the partition plate 318 can be integrally formed with the main body 311, or can be fixedly arranged on the main body 311 through a fixing structure such as a buckle structure, which is not limited herein.

[0034] In an embodiment, an end clamping portion 319 is further included at one end of each receiving groove 316 away from the rotating shaft 35. The end clamping portion 319 is located at one end of the receiving groove 316 and is formed by a part of the partition plate 318, one end wall of the receiving groove 316, and a side wall of the receiving groove 316 opposite to the partition plate 318, and is used for receiving and fixing the end of the clamping block 313.

[0035] In one embodiment, the partition 318 is further formed with an arc-shaped recess that matches the notch 315 to jointly form the locking hole 38.

[0036] Each engaging block 313 includes a first protrusion 3131 and a second protrusion 3132 at both ends. The thickness of the first protrusion 3131 is greater than that of the second protrusion 3132. Among them, the first protrusion 3131 is engaged and received in the end engaging portion 319. Since the first protrusion 3131 is thicker and is disposed in the end engaging portion 319, this can further prevent the engaging block 313 from detaching from the main body 311.

[0037] In this embodiment, the case where the conversion device 30 has two receiving grooves 316 and engaging blocks 3134, 3135 will be described. At least two receiving grooves 316 include a first receiving groove 3161 and a second receiving groove 3162. The first receiving groove 3161 and the second receiving groove 3162 are respectively located on both sides in the length direction of the locking member 31. At least two engaging blocks 313 include a first engaging block 3134 and a second engaging block 3135. The first engaging block 3134 and the second engaging block 3135 are respectively disposed in the first receiving groove 3161 and the second receiving groove 3162.

[0038] It should be noted that the widths of the first engaging block 3134 and the second engaging block 3135 may be the same or different, and are not limited herein.

[0039] For the convenience of the following description, the case where the two locking members 31 include a first locking member 32 and a second locking member 33 will be described.

[0040] In one embodiment, please refer to Figure 4 、 Figure 6 and Figure 7 , in Figure 6 and Figure 7 , a first recess 3136 is formed on the upper surface of the first engaging block 3134, and a second recess 3137 is formed on the upper surface of the second engaging block 3135. The overall thicknesses of the first engaging block 3134 and the second engaging block 3135 are the same, and the arcs of the first recess 3136 and the second recess 3137 are the same. Thus, when the first locking member 31 and the second locking member 33 are closed, the first engaging block 3134 and the second engaging block 3135 can form a symmetric receiving space for receiving the cross bar 51 of the counterweight 50. Among them, in Figure 6 , the depression depths of the first recess 3136 and the second recess 3137 are less than those in Figure 7 . Therefore, Figure 6 , the height of the receiving space formed is greater than that in Figure 7The height of the accommodating space formed therein, so as to satisfy the cross bar 51 on which counterweight members 50 of different sizes can be installed.

[0041] In another embodiment, please refer to Figure 8 , in Figure 8 , a first concave portion 3136 is formed on the upper surface of the first engaging block 3134, a second concave portion 3137 is formed on the upper surface of the second engaging block 3135. The overall thickness of the first engaging block 3134 and the second engaging block 3135 is the same, and the radian of the first concave portion 3136 and the second concave portion 3137 is different. The first engaging block 3134 of the first locking member 31 and the second engaging block 3135 of the second locking member 33 are disposed opposite to each other, and the second engaging block 3135 of the first locking member 31 and the first engaging block 3134 of the second locking member 33 are disposed opposite to each other. Therefore, when the first locking member 31 and the second locking member 33 are closed, the first engaging block 3134 and the second engaging block 3135 can form an asymmetric accommodating space. In this way, the corresponding engaging block 313 can be selected according to the shape of the cross bar 51 of the counterweight member 50.

[0042] In other embodiments, it may also be configured that the overall thickness of the first engaging block 3134 and the second engaging block 3135 is different, and the radian of the first concave portion 3136 and the second concave portion 3137 is the same. In this way, three accommodating spaces of different sizes can be formed by combining the first engaging block 3134 and the second engaging block 3135 to adapt to cross bars 51 of various sizes.

[0043] It should be noted here that the surfaces of the concave portions of the first engaging block 3134 and the second engaging block 3135 both protrude from the notch 315, that is, the height of the accommodating space formed by the first engaging block 3134 and the second engaging block 3135 is smaller than the aperture of the locking hole 38. In this way, the first engaging block 3134 and the second engaging block 3135 can fully abut against the cross bar 51 of the configuring member 50, further suppressing the axial or lateral movement of the cross bar 51 of the counterweight member 50 in the locking hole 38.

[0044] Furthermore, please refer to Figure 4 and Figure 5 , the bottom surface 3138 of each engaging block 313 is planar, and the bottom wall 3163 of the accommodating groove 316 is also formed as planar. Of course, in other embodiments, the bottom surface 3138 of each engaging block 313 and the bottom wall 3163 of the accommodating groove 316 may also be arc-shaped or other shapes, which are not limited herein.

[0045] Further, each engaging block 313 is provided with a buffer hole 3139 penetrating from one side wall towards the opposite side wall. The number and size of the buffer holes are selected according to requirements and are not limited herein. By providing buffer holes in the engaging block 313, it is beneficial to increase the elasticity and compression amount of the engaging block 313, so that each engaging block 313 can deform through the buffer hole 3139. Thus, it can be applied to fitness equipment 100 of different sizes.

[0046] Further, the engaging block 313 is made of a flexible material, which can be but is not limited to silicone. Inside the locking hole 38, it can prevent the cross bar 51 of the counterweight 50 from moving axially or laterally within the locking hole 38.

[0047] Hereinafter, the part where the two locking members 31 (i.e., the first locking member 32 and the second locking member 33) are connected to the rod member 10 will be described.

[0048] One end of the first locking member 32 close to the rod member 10 is formed with a first receiving groove 321 along a direction perpendicular to the length direction of the first locking member 32. A first positioning hole 322 is opened in the middle of the first receiving groove 321, and a threaded portion 323 is provided on the inner wall of the first positioning hole 322.

[0049] One end of the second locking member 33 close to the rod member 10 is formed with a second receiving groove 331 along a direction perpendicular to the length direction of the second locking member 33. The shape of the second receiving groove 331 is the same as the shape of the first receiving groove 321, so that when the first locking member 32 and the second locking member 33 are in a closed state, the first receiving groove 321 and the second receiving groove 331 form a receiving hole 38. A second positioning hole 332 opposite to the first positioning hole 322 is opened in the middle of the second receiving groove 331.

[0050] The fastener 37 is arranged on the second locking member 33, and the fastener 37 includes a fastening screw 371, a stopper 373 and a rotating head 375. Specifically, the rotating head 375 is located on the outer side of the first locking member 32 away from the first locking member 32, and the rotating head 375 is provided with a plurality of recesses, and the bottom wall of the recess is provided with a plurality of raised lines, so as to facilitate the rotation of the hand. One end of the fastening screw 371 connected to the rotating head 375 is located outside the second locking member 33, and the other end of the fastening screw 371 passes through the second positioning hole 377 of the second locking member 33 and is locked with the first locking member 32. The stopper 373 is sleeved on the fastening screw 371 from the inner wall of the second locking member 33 along the other end of the fastening screw 371 until it contacts the inner wall of the second locking member 33. The diameters of the rotating head 375 and the limiting member 373 are larger than the diameters of the second positioning hole 377 and the fastening screw 371, so that the rotating head 375 limits the fastening screw 371 upward, and the limiting member 373 limits the fastening screw 371 downward, so that when in an idle state, the fastening screw 371 will not be separated from the second positioning hole 332 and lost. In this embodiment, the limiting member 373 is a nut that matches the fastening screw. It can be understood that the limiting member 373 can also be other components that play a limiting role.

[0051] The fastening screw 371 passes through the second positioning hole 332 and the limiting hole 111 in sequence and is inserted into the first positioning hole 322, so that the second locking member 33 is connected to the other end of the first locking member 32 away from the rotating shaft 35, and the insertion portion 113 of the rod member 10 is locked through the locking hole 330. The first locking member 32 is also provided with an auxiliary positioning rod 324, which passes through the auxiliary positioning hole 113 of the insertion portion 113 to play an auxiliary positioning role.

[0052] The fastening screw 371 can be rotated to different positions of the threaded portion 323 of the first positioning hole 322, so that the fastening screw 371 enters the first positioning hole 322 to different depths. The maximum diameter of the rod of the counterweight 50 that the conversion device 30 can engage depends on the depth of the fastening screw 371 entering the first positioning hole 322. When the bottom end of the fastening screw 371 engages with the first circle of the threaded portion 323, the diameter of the engaging hole 310 is the maximum diameter of the rod that can be engaged. When the two opposite engaging blocks 3111 are in contact, the maximum distance between the two engaging blocks 3111 is the minimum diameter of the rod that can be engaged.

In addition, for the sake of convenience of description, the same reference numerals are given to components having the same functions as those described in the above embodiment, and description thereof will be omitted.

[0055] The fitness equipment 200 in this embodiment is different from the fitness equipment 100 in the first embodiment in that the fitness equipment 200 in this embodiment is a dumbbell, that is, the grip 60 replaces the rod member 10 in the first embodiment, and the other components are the same as those in the first embodiment, which will not be elaborated here.

[0056] The grip 60 includes a grip hole 61 that provides a holding space for the user's hand and an insertion portion 62 that is inserted into the locking hole 330. At least two through transfer holes 63 are provided in different directions of the insertion portion. The transfer holes 63 are aligned with the first positioning holes 322, and the fastening screws 371 sequentially pass through the second positioning holes 332, the transfer holes 63, and the first positioning holes 322, so that the conversion device 30 and the grip 60 are connected together. Let the fastening screw 371 disengage from the first transfer hole 63, rotate the orientation of the grip 60 so that the second transfer hole 63 is aligned with the first positioning hole 322, and the fastening screw 371 sequentially passes through the second positioning hole 332, the transfer hole 63, and the first positioning hole 322, so that the conversion device 30 and the grip 60 are connected together.
