Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a counterweight structure for fitness equipment used in high-intensity recovery training. Background Technology

[0002] Fitness equipment refers to instruments and equipment used for physical exercise, strength training, rehabilitation therapy, or physical fitness testing. It aims to help users increase muscle strength, improve cardiopulmonary function, enhance flexibility, or conduct rehabilitation training. It is widely used in gyms, homes, hospitals, sports training centers, and other places.

[0003] Currently, counterweights and weight bars are core components of strength training equipment (such as barbells, dumbbells, multi-gyms, etc.), mainly used to adjust training load to meet the needs of different intensities of exercise.

[0004] In existing fitness equipment, guide rods typically pass through both ends of the weight block to guide it during lifting and lowering, or the sidewall of the weight block is fitted against the inner wall of the equipment shell to guide it, thereby reducing weight block tilt. This not only helps ensure the safety and stability of the equipment but also improves user experience and training effectiveness. However, whether using guide rods or sidewalls, the friction between the weight block and other components increases during lifting and lowering, adding extra weight to the weight block. When multiple weight blocks are used simultaneously, the extra weight increase is more significant, affecting the accuracy of training load adjustment and accelerating weight block wear, thus reducing its lifespan. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing guiding method of the counterweight increases friction and leads to an additional weight of the counterweight, and to propose a counterweight structure for fitness equipment for high-intensity recovery training.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A counterweight structure for fitness equipment used in high-intensity recovery training includes counterweights. The counterweights have a bearing surface, a positioning surface, and a contour surface. A positioning structure is provided on the bearing surface, and a guiding structure is provided on the positioning surface. When multiple counterweights are stacked to form surface contact, the positioning structure and the guiding structure cooperate to make the contour surfaces of the stacked counterweights coincide.

[0008] To facilitate guiding the positioning structure, preferably, the guiding structure includes a stepped hole penetrating the counterweight, the positioning structure is embedded in the stepped hole, and the positioning structure extends above the bearing surface. When multiple counterweights are stacked to form surface contact, the extended end of the positioning structure is inserted into the stepped hole.

[0009] To facilitate extension into the larger end of the stepped hole, the positioning structure further includes a positioning head, with a plug rod fixedly disposed at the bottom of the positioning head. The plug rod is plugged into the stepped hole, and the positioning surface of the positioning head extends to the larger end of the stepped hole.

[0010] In order to automatically extend into the larger end of the stepped hole, the positioning surface is further shaped as an umbrella, dome, or pyramid.

[0011] Preferably, it further includes a weight rod for connecting multiple counterweights in series, wherein the side wall of the weight rod has multiple first insertion holes distributed along the axial direction, the counterweight has a central hole, the weight rod is inserted into the central hole, and the side wall of the counterweight has a second insertion hole penetrating the central hole, and the counterweight is fixed to the weight rod by a counterweight insertion rod.

[0012] Furthermore, it also includes a base for supporting the counterweight and a fixing block that is bolted to the weight bar. The fixing block is located on top of the counterweight, and the base and the fixing block are connected to the counterweight via a positioning structure and a guiding structure, respectively.

[0013] Compared with the prior art, this utility model provides a counterweight structure for fitness equipment used in high-intensity recovery training, which has the following beneficial effects:

[0014] 1. The weight structure of this high-intensity recovery training fitness equipment uses matching positioning and guiding structures on the bearing and positioning surfaces of the weights. When multiple weights are stacked and form surface contact, the positioning and guiding structures work together to make the contour surfaces of the stacked weights coincide, reducing the occurrence of skewness. It can also reduce the friction between the weights and other components. When adjusting the training load, it can ensure the adjustment accuracy of the weights and improve the use effect.

[0015] 2. The weight structure of this high-intensity recovery training fitness equipment has a positioning hole on the bottom contact surface of the fixed block to facilitate guidance between it and the adjacent weight below. A positioning rod is installed on the top contact surface of the base. The positioning head of the positioning rod matches the positioning hole at the bottom of the adjacent weight above. At this time, it can be ensured that multiple weights in contact with each other are placed in sequence.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technologies. This utility model sets mutually matching positioning and guiding structures on the bearing surface and positioning surface of the counterweights respectively. When multiple counterweights are stacked and form surface contact, the positioning structure and guiding structure cooperate to make the contour surfaces of the multiple stacked counterweights coincide, reducing the occurrence of skewness. It can also reduce the friction between the counterweights and other components. When adjusting the training load, it can ensure the adjustment accuracy of the counterweights and improve the use effect. Attached Figure Description

[0027] Example:

[0028] Reference Figures 1-7 A counterweight structure for high-intensity recovery training fitness equipment includes a counterweight 2, preferably a cuboid structure. The counterweight 2 has a bearing surface, a positioning surface, and a contour surface. The bearing surface is located on the top end face of the counterweight 2, the positioning surface is located on the bottom end face, and the contour surface is the side wall of the counterweight 2. A positioning structure is provided on the bearing surface, and a guiding structure is provided on the positioning surface. When multiple counterweights 2 are stacked and form surface contact, the positioning structure and the guiding structure cooperate to make the contour surfaces of the stacked counterweights 2 coincide. The system also includes a weight bar 1 for connecting multiple counterweights 2 in series. The side wall of the weight bar 1 has multiple first insertion holes 101 distributed along the axial direction, and a central hole 201 is provided on the counterweight 2. 1. The counterweight 2 is inserted into the center hole 201, and a second insertion hole 202 is opened on the side wall of the counterweight 2, which penetrates the center hole 201. The counterweight 2 is fixed to the weight rod 1 by the counterweight insertion rod 5, that is, the counterweight insertion rod 5 is inserted into the second insertion hole 202 and the first insertion hole 101, and extends out from the second insertion hole 202 at the other end. There are two to twenty counterweights 2. When the weight of a single counterweight 2 is relatively heavy, eight are preferred. When the weight of a single counterweight 2 is relatively light, ten are preferred. There are two to thirty first insertion holes 101. Here, we prefer twenty. In use, one end of the counterweight insertion rod 5 is passed through the second insertion hole 202 and the first insertion hole 101 in sequence to fix the counterweight 2 to the weight rod 1.

[0029] In use, by setting matching positioning and guiding structures on the bearing surface and positioning surface of the counterweight 2 respectively, when multiple counterweights 2 are stacked to form surface contact, the positioning structure and guiding structure cooperate to make the contour surfaces of multiple stacked counterweights 2 coincide, reducing the occurrence of skewness. It can also reduce the friction between the counterweight 2 and other components. When adjusting the training load, it can ensure the adjustment accuracy of the counterweight 2 and improve the use effect.

[0030] Reference Figure 5 Here, the guiding structure includes a stepped hole penetrating the counterweight 2, in which the positioning structure is embedded and extends above the bearing surface. When multiple counterweights 2 are stacked to form surface contact, the extended end of the positioning structure is inserted into the stepped hole. Here, the stepped hole consists of a through hole 203 and a positioning hole 204. The inner diameter of the positioning hole 204 is larger than the inner diameter of the through hole 203. The positioning structure is embedded in the through hole 203, and the extended end extends into the positioning hole 204 to facilitate guiding the positioning structure.

[0031] Reference Figure 5 Here, the positioning structure includes a positioning head 3, with a connecting rod 301 fixedly installed at the bottom of the positioning head 3. The connecting rod 301 is inserted into the stepped hole, that is, into the through hole 203. The positioning surface of the positioning head 3 extends to the large end of the stepped hole, that is, into the positioning hole 204. The positioning surface of the positioning head 3 matches the positioning hole 204. Moreover, the shape of the positioning surface is umbrella-shaped, dome-shaped, pyramid-shaped, or frustum-shaped. Here, we prefer the umbrella shape. When the weight bar 1 slides down with the upper counterweight 2, the positioning head 3 of the lower counterweight 2 will automatically slide into the positioning hole 204 at the bottom of the upper counterweight 2 to achieve automatic positioning. That is, when two adjacent counterweights 2 are placed close together, the top of the positioning rod extends into the positioning hole 204, which not only facilitates guidance but also reduces friction. When adjusting the training load, it can ensure the adjustment accuracy of the counterweight 2 and improve the use effect.

[0032] Reference Figures 1-4 When the length of the box on which the weights 2 are placed is longer on the side facing the user, the two through holes 203 are symmetrically distributed about the second insertion hole 202. When the length of the box on which the weights 2 are placed is shorter on the side facing the user, the two through holes 203 are inclined and distributed on both sides of the second insertion hole 202 to avoid interference with the insertion of the weight rod 5 and to facilitate use.

[0033] Reference Figure 1 and Figure 2A counterweight structure for high-intensity recovery training fitness equipment includes a base 4 for supporting the counterweight 2 and a fixing block 6 fixed to the weight bar 1 by bolts. The bottom of the base 4 is placed on the fitness equipment, and the weight bar 1 is slidably connected to the base 4. The fixing block 6 is also a counterweight 2, except that the fixing block 6 is detachably connected to the weight bar 1 by bolts. The fixing block 6 is located on the top of the counterweight 2. The base 4 and the fixing block 6 are connected to the counterweight 2 through a positioning structure and a guiding structure, respectively. That is, a positioning hole 204 is opened on the bottom contact surface of the fixing block 6 to facilitate guidance between it and the adjacent counterweight 2 below. A positioning structure is installed on the top contact surface of the base 4. The positioning head 3 of the positioning structure matches the positioning hole 204 at the bottom of the adjacent counterweight 2 above. At this time, it can be ensured that multiple counterweights 2 in mutual contact are placed in sequence.

[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
