The terminology used in the description of the present application herein only for the purpose of describing specific embodiments of the present application and is not intended to limit the present application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] A multifunctional sports fitness equipment, such as Figure 1 As shown, comprising a crossbar member 10 in the form of a cylinder, a plurality of weight members 20 reciprocally slidable along the axial direction on both sides of the crossbar member 10, and a detent assembly 30 provided on the crossbar member 10 for detent of the weight members 20;

[0027] Among them, as Figure 2 and Figure 3As shown in the drawings, the counterweight 20 is provided with two in the present embodiment, respectively located on both sides of the horizontal rod member 10, the horizontal rod member 10 includes the rod body 101 with the inner cavity 105, the plurality of through holes 103 through the outer wall of the rod body 101 and the inner cavity 105 communication, in the present embodiment, the number of through holes 103 is four, and two two symmetrical arrangement; the counterweight 20 includes the rotating seat 202 connected with the rod body 101 slidingly, the recess 204 opened in the inner side of the rotating seat 202, and the weight block 201 rotatably connected on the outer wall of the rotating seat 202;

[0028] As shown in the drawings, Figure 5 The clamping assembly 30 includes a plurality of sliding sleeves 301 arranged at the inner cavity 105 of the rod body 101, in the present embodiment, the number of sliding sleeves 301 is two, distributed in the middle and one side of the extrusion block 302, the extrusion block 302 connected with the sliding sleeve 301 slidingly, the recess 303 with slope corresponding to the number of through holes 103 opened on the extrusion block 302, and the clamping block 306 connected with the through hole 103 slidingly, the recess 303 and the clamping block 306 extrusion fit; when the clamping block 306 is clamped into the recess 204 of the rotating seat 202, the rotating seat 202 cannot slide on the rod body 101.

[0029] It is understandable that the multi-functional sports and fitness equipment is initially in the form of dumbbells. When it needs to be changed to roller equipment, the operator can push the compression block 302 deeper into the inner cavity 105. The groove 303 on the compression block 302 also moves together. When the groove 303 aligns with the corresponding locking block 306, the locking block 306 will move downwards under its own weight. As the locking block 306 moves downwards, it will no longer be located in the recess 204 of the rotating seat 202. At this time, the rotating seat 202 can slide on the rod 101. The operator then slides the two counterweights 20 towards the middle of the rod 101. When the two counterweights 20 slide to their limit position towards the middle of the rod 101, the recess 204 aligns with the locking block 306 in the middle. The operator can then pull the compression block 302 deeper into the inner cavity 105. When the weight is slid out, the ramp on the groove 303 of the compression block 302 will press against the locking block 306, and the locking block 306 will move upward and slide into the recess 204, thereby restricting the sliding of the counterweight 20 and completing the operation of changing the roller equipment. The exerciser can hold the two sides of the bar 101 to make the weight block 201 contact the ground, and then push the weight block 201 back and forth to achieve waist and abdominal exercise. When it is necessary to change the roller equipment to dumbbells, the operator only needs to push the compression block 302 deeper into the inner cavity 105, so that the locking block 306 in the middle slides out of the recess 204. Then, slide the two counterweights 20 to the two sides of the bar 101, and then pull the compression block 302 away from the depth of the inner cavity 105, so that the outer locking block 306 slides into the recess 204 to complete the operation of changing dumbbells.

[0030] In summary, by pushing the compression block 302 deeper into the inner cavity 105, when the groove 303 aligns with the corresponding locking block 306, the locking block 306 will move downwards under its own weight. As the locking block 306 moves downwards, it will no longer be located within the recess 204 of the rotating seat 202. At this time, the rotating seat 202 can slide on the rod 101. The operator then slides the two counterweights 20 towards the middle of the rod 101. When the two counterweights 20 slide to their limit position towards the middle of the rod 101, the recess 204 aligns with the locking block 306 in the middle. The operator can then pull the compression block 302 deeper into the inner cavity 105. During this sliding motion, the ramp on the groove 303 of the compression block 302 will compress the locking block 306, causing the locking block 306 to move upwards and slide into the recess 204. This restricts the sliding of the counterweights 20, completing the operation of changing the roller equipment. This achieves the effect of quick and convenient change of exercise method.

[0031] like Figure 2 As shown, the rod body 101 has sliding grooves 102 on both sides, and the rotating seat 202 has a protrusion 203 on the inner side. The rotating seat 202 is slidably connected to the sliding grooves 102 of the rod body 101 through the protrusion 203.

[0032] It can be understood that the slide 102 is in the shape of a straight line. The two ends of the slide 102 are the extreme positions of the sliding seat 202. When the protrusion 203 on the rotating seat 202 contacts the end of the slide 102, the rotating seat 202 slides to the extreme position of the end of the slide 102. At this time, the concave hole 204 and the locking block 306 are aligned.

[0033] Multiple grooves 102 are provided on both sides of the rod 101. The multiple grooves 102 are arranged in a circular array along the axis of the rod 101. The inner side of the rotating seat 202 is provided with protrusions 203 corresponding to the number of grooves 102. The protrusions 203 are located in the grooves 102 respectively.

[0034] In this embodiment, there are four slide grooves 102. By setting multiple slide grooves 102, when the exerciser changes to roller equipment for exercise, when the exerciser holds the two sides of the bar 101, the exerciser's hands come into contact with the slide grooves 102, so that the slide grooves 102 can achieve the anti-slip effect when the exerciser is performing waist and abdominal exercises.

[0035] like Figure 2 As shown, the middle part of the rod 101 has a plurality of hemispherical protrusions 104 arranged in a ring array along its axis.

[0036] It's understandable that the raised 104 section can provide a non-slip effect when exercisers switch to dumbbells.

[0037] like Figure 4 As shown, a spring 205 is provided between the weight block 201 and the rotating seat 202.

[0038] It is understandable that when the exerciser switches to the roller equipment, when the exerciser pushes the weight block 201 to move on the ground, the weight block 201 also rotates on the rotating seat 202. The rotation of the weight block 201 will cause the spring 205 to deform. When the exerciser pushes the weight block 201 back to its original position, the spring 205 will also return to its original position. This can help the exerciser to perform waist and abdominal training.

[0039] like Figure 5 As shown, a spring 307 is provided between the locking block 306 and the inner wall of the rod 101.

[0040] It is understandable that when the pressing block 302 presses the card block 306, the spring 307 is in a compressed state. When the card block 306 is aligned with the groove 303 on the pressing block 302, the spring 307 will reset and drive the card block 306 to move downward and slide out of the recess 204.

[0041] likeFigure 5 As shown, the locking assembly 30 also includes a connecting block 304 connected to the end of the pressing block 302, and a bolt 305 rotatably connected to the connecting block 304. The bolt 305 is threadedly connected to the inner cavity 105 of the rod body 101.

[0042] It is understood that the operator can rotate the bolt 305 in the forward direction. The rotation of the bolt 305 will push the connecting block 304 to move deeper into the inner cavity 105, thereby causing the pressing block 302 to move deeper into the inner cavity 105. When the operator rotates the bolt 305 in the reverse direction, the bolt 305 will drive the connecting block 304 to move away from the inner cavity 105, and the connecting block 304 will drive the pressing block 302 to move out of the inner cavity 105.

[0043] like Figure 5 As shown, a vent hole 106 is provided on the side of the rod 101 away from the bolt 305. The vent hole 106 penetrates the side wall of the rod 101 and communicates with the inner cavity 105.

[0044] It is understandable that a vent hole 106 is provided on the rod body 101 so that when the bolt 305 moves in the inner cavity 105, the gas in the inner cavity 105 is not difficult to be discharged, and can be quickly discharged through the vent hole 106.
