[0026] The present application provides a strength training device, referring to Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of an embodiment of the strength training device provided by the present application.

[0027] As shown in Figure 1 , the strength training device 10 includes a training platform 400, a pull rope 300, a support assembly 200 and a pull-down assembly 100.

[0028] The training platform 400 can be placed on the ground or other support surface for training by users stepping on it. The fixed end of the pull rope 300 is connected to the training platform 400. One end of the support assembly 200 is connected to the training platform 400, and the other end is connected to the downward pulling assembly 100, through which the free end of the pull rope 300 passes. The fixed end of the pull rope 300 is the end connected to the training platform 400, and the free end of the pull rope 300 is the end that can move freely. The top of the training platform 400 is provided with a rope outlet through which the free end of the pull rope 300 passes. The rope outlet can be one or two. When there is one, it can be located in the middle of the training platform 400. When there are two, they can be located at the two ends of the training platform 400.

[0029] The fixed end of the pull rope 300 is fixed to the training platform 400, and it is in a relatively static state with the training platform 400; the free end of the pull rope 300 can move closer to or away from the training platform 400 under the action of external force. The fixed end of the pull rope 300 can be located inside the housing of the training platform 400, and the pull rope 300 can be partially accommodated in the training platform 400, so that the handle of the free end of the pull rope 300 abuts the outer surface of the housing of the training platform 400. Therefore, accommodating the pull rope 300 in the training platform 400 can avoid the situation that the pull rope 300 is damaged or tangled or the user trips when not in use, and also makes the structure of the training platform 400 aesthetically pleasing. The handle connected to the free end of the pull rope 300 is exposed outside the training platform 400 to facilitate the user to pull the pull rope 300 out of the training platform 400. The training platform 400 also includes a resistance source inside, which is connected to the fixed end of the pull rope 300 to apply a load to the pull rope 300, serving as resistance training. The resistance source can be one or more of a motor, a magnetic resistance, and a spring, but is not limited thereto, as long as it has the function of providing resistance or load. When using the strength training device 10, the trainer steps on the training platform 400 and applies an external force to the free end of the pull rope 300, so that the free end of the pull rope 300 moves away from the training platform 400 under the action of the external force, so that the trainer can achieve training by pulling the pull rope 300.

[0030] One end of the support assembly 200 is connected to the training platform 400, and the other end of the support assembly 200 is connected to the pull-down assembly 100. The distance from the end of the support assembly 200 connected to the pull-down assembly 100 to the training platform 400 is adjustable, and / or the position of the pull-down assembly 100 on the support assembly 200 is adjustable, so that the distance of the pull-down assembly 100 relative to the training platform 400 is adjustable, so as to meet the exercise needs of different heights. The angle of the support assembly 200 relative to the training platform 400 is adjustable, that is, the support assembly 200 can rotate around the connection point between the support assembly 200 and the training platform 400, so as to adjust the angle between the support assembly 200 and the training platform 400 during use, so as to meet the training needs of different stretching ranges or the needs of users with different arm spans. When the support assembly is not in use, the angle and distance of the support assembly 200 relative to the training platform 400 can also be adjusted to facilitate the storage of the support assembly 200. In an embodiment, the support assembly 200 is detachably connected to the side of the training platform 400, and the side is one side of the long side of the training platform 400.

[0031] The pull-down assembly 100 can pass through the free end of the pull rope 300. The pull-down assembly 100 is arranged at the end of the support assembly 200 away from the training platform 400. The free end of the pull rope 300 can pass through the pull-down assembly 100 and use the pull-down assembly 100 as a fulcrum to move towards the training platform 400 under the action of an external force, thereby realizing the pull-down training. The pull rope 300 is composed of at least one rope. In an embodiment, the pull rope 300 is composed of one rope. In another embodiment, the pull rope 300 is composed of at least two ropes connected to each other, so as to solve the problem that the length of the pull rope 300 may be difficult to better realize the pull-down training in actual application scenarios.

[0032] Through the above embodiments, by arranging the pull-down assembly 100 and the support assembly 200 on the training platform 400, the trainer only needs to stand on the training platform 400 and pull out the pull rope 300 to pass through the pull-down assembly 100, so as to realize the pull-down training by applying a pulling force downward. The whole strength training device 10 has a simple structure and can effectively add the function of pull-down training on the training platform 400, thereby improving the diversity of product functions. In addition, the angle of the support assembly 200 relative to the training platform 400 is adjustable, and the distance of the pull-down assembly 100 relative to the training platform 400 is adjustable, so as to meet the exercise needs of different amplitudes of the pull rope 300 and different heights of the pull rope 300.

[0033] As Figure 1As shown, in an embodiment, the pull-down assembly 100 and the support assembly 200 in the strength training device 10 can be one set, the corresponding pull rope 300 can be one or two, and the handle at the end of the pull rope 300 for applying external force can be a horizontal bar or a grip, a pull ring, etc. In another embodiment, the pull rope 300, the support assembly 200 and the pull-down assembly 100 are two sets. Exemplarily, when one pull rope 300 is configured on the training platform 400, the strength training device 10 is provided with one pull-down assembly 100, and the pull rope 300 is wound around the pull-down assembly 100, so that the pull-down training can be realized. When two pull ropes 300 are configured on the training platform 400, bilateral training can be realized, and the strength training device 10 is provided with one or two pull-down assemblies 100, that is, one pull rope 300 or two pull ropes 300 can be wound around one pull-down assembly 100 for training, or two pull ropes can be wound around one pull-down assembly 100 for exercise.

[0034] Referring to Figure 2 , Figure 2 is a structural schematic diagram of another embodiment of the strength training device 10 provided by the present application.

[0035] As Figure 2 shown, the pull rope 300, the pull-down assembly 100 and the support assembly 200 in the strength training device 10 are two sets, each set of the pull-down assembly 100, the support assembly 200 and the pull rope 300 presents a corresponding relationship, and the handle at the end of the pull rope 300 for applying external force can be a grip. The trainer can hold two grips with two hands and pull two pull ropes 300 to perform bilateral pull-down training.

[0036] Referring to Figures 1-5 , Figure 3 is Figure 2 an enlarged schematic diagram of an embodiment of the structure in the dashed box, Figure 4 is Figure 2 an enlarged schematic diagram of another embodiment of the structure in the dashed box, Figure 5 is Figure 4 an exploded schematic diagram of an embodiment of the adapter support 110.

[0037] The pull-down assembly 100 comprises an adapter bracket 110 connected with the bracket assembly 200 and a first pulley 120 connected with the adapter bracket 110 and rotatable about its axis relative to the adapter bracket 110. A free end of the pull rope 300 is pulled out from the training platform 400 and abuts against a side surface of the first pulley 120 in a circumferential direction of the first pulley 120 to take the first pulley 120 as a first fulcrum of the pull rope 300. The side surface of the first pulley 120 can be provided with a groove to facilitate the pull rope 300 to be accommodated in the groove of the first pulley 120, so as to prevent the pull rope 300 from being separated from the first pulley 120 during the pull-down training. The first pulley 120 is rotatably connected with the adapter bracket 110, so that the first pulley 120 can rotate about its axis, and when the pull rope 300 is pulled down with the first pulley 120 as the fulcrum, the rotation of the first pulley 120 can reduce the friction loss and force loss of the pull rope 300.

[0038] The pull-down assembly 100 comprises a universal assembly connected with the adapter bracket 110, and a free end of the pull rope 300 is led out from the first pulley 120 through the universal assembly. The universal assembly can adapt to the pulling of the pull rope 300 in different directions, so that the user can feel more smooth when pulling down in any direction. Meanwhile, the free end of the pull rope 300 is provided with a limiting block 310, and the universal assembly can limit the limiting block 310 to block the recovery of the pull rope 300, so as to avoid the pull rope 300 from being withdrawn to the training platform 400 when the user stops pulling the pull rope 300.

[0039] In an embodiment, the universal assembly comprises a limiting bracket 150 rotatably connected with the adapter bracket 110, for example, the limiting bracket 150 and the adapter bracket 110 are connected through a rotating sleeve. The universal assembly further comprises a second pulley 140 connected with the limiting bracket 150, and the limiting bracket 150 is used for supporting the second pulley 140. The second pulley 140 is rotatable about its axis relative to the limiting bracket 150. The limiting bracket 150 and the second pulley 140 can be assembled as an integral component on the adapter bracket 110, and the second pulley 140 is located on a side of the first pulley 120 away from the training platform 400.

[0040] The pull rope 300 is pulled out from the training platform 400, passes through the first pulley 120 as the first fulcrum of the pull rope 300, and then winds around the second pulley 140 to take the second pulley 140 as the second fulcrum of the pull rope 300, so that the trainer can realize the pull-down training by pulling the pull rope 300. In the embodiment, through the cooperation of the first pulley 120 and the second pulley 140, the pull rope 300 takes the first pulley 120 as the first fulcrum in the process of pull-down training, and the friction when the pull rope 300 changes direction can be reduced through the first pulley 120. At the same time, since the limiting support 150 is rotationally connected with the adapter support 110, the second pulley 140 serves as the second fulcrum when the pull rope 300 is pulled down, so as to adapt to different pulling directions. In addition, due to the rotation of the second pulley 140 in the process of pulling down the pull rope 300, the friction on the pull rope 300 can be further reduced, so that the protection effect on the pull rope 300 is more optimal.

[0041] The limiting support 150 includes a limiting portion 151, which is arranged in the radial direction of the second pulley 140 and spaced from the second pulley 140. The spacing between the limiting portion 151 and the second pulley 140 is not greater than the size of the limiting block 310, so that the limiting block 310 of the pull rope 300 can be limited by the limiting portion 151 to block the recovery of the pull rope 300. The limiting portion 151 is provided with a breakage to enable the pull rope 300 to pass through the breakage and be wound around the side surface of the second pulley 140. Specifically, the breakage of the limiting portion 151 divides the limiting portion into two parts, and the spacing between the two parts is greater than the diameter of the pull rope 300 and less than the size of the limiting block 310, so that the pull rope 300 can pass through the limiting portion 151 and be wound around the side surface of the second pulley 140. The limiting portion 151 protrudes from the side surface of the second pulley 140. The height of the limiting portion 151 protruding from the side surface of the second pulley 140 (i.e., the spacing between the limiting portion 151 and the second pulley 140) can be set according to actual conditions, which can meet the requirement of limiting the limiting block 310 of the pull rope 300 by the limiting portion 151 to block the recovery of the pull rope 300. Therefore, in the embodiment, the free end of the pull rope 300 can be limited at the limiting portion 151 by the design of the limiting block 310, so that the pull rope 300 can be prevented from being withdrawn into the training platform 400 when the pull-down is paused.

[0042] In an embodiment, the pull-down assembly 100 includes a universal sleeve 130 connected to the side of the adapter support 110 away from the support assembly 200. The universal sleeve 130 is provided with a through hole 131, and the side wall of the universal sleeve 130 is provided with an opening 132 communicating with the through hole 131. The pull rope 300 is clamped into the through hole 131 through the opening 132, and the outer peripheral size of the limiting block 310 is greater than the radial size of the through hole 131.

[0043] The universal sleeve 130 can adapt to the pulling of the pull rope 300 in different directions, so that the user feels more smooth when pulling in any direction during the down-pull training. At the same time, the universal sleeve 130 can limit the limiting block 310 to block the recovery of the pull rope 300, so as to avoid the pull rope 300 from retracting back to the training platform 400 when the user stops pulling the pull rope 300. The universal sleeve 130 can be in a hollow cylindrical shape, and the universal sleeve 130 is located on the side of the first pulley 120 away from the support assembly 200 and is connected with the adapter support 110, so that the pull rope 300 passes through the first pulley 120 and the universal sleeve 130 in turn, and is clamped into the through hole 131 through the opening 132, and then the first pulley 120 is used as a fulcrum for down-pull training. Wherein, the limiting block 310 of the pull rope 300 can be in a spherical shape, and the outer diameter of the limiting block 310 can be greater than the radial dimension of the through hole 131, so as to limit the other end of the pull rope 300 at the universal sleeve 130 through the limiting block 310, so as to avoid the pull rope 300 from retracting back to the training platform 400 when the down-pull is paused.

[0044] Wherein, the adapter support 110 includes a first plate body 111, a second plate body 112, a third plate body 113 and a second connecting rod 115, the second plate body 112 is arranged in a spaced manner with the first plate body 111, the first plate body 111 and the second plate body 112 are connected with the third plate body 113 respectively, and the first plate body 111 and the second plate body 112 are located on the same side of the third plate body 113, so as to form a groove through the first plate body 111, the second plate body 112 and the third plate body 113, the groove can be in a U-shaped shape, the second connecting rod 115 and the first pulley 120 are located in the U-shaped groove, so as to protect the first pulley 120 through the first plate body 111, the second plate body 112 and the third plate body 113. The first connecting rod 114 is arranged on the surface of the first plate body 111 away from the second plate body 112, and the first connecting rod 114 is connected with the support assembly 200, the second connecting rod 115 is arranged on the third plate body 113, the second connecting rod 115 is located between the first plate body 111 and the second plate body 112, and is arranged on the same side of the first plate body 111 and the second plate body 112, the first pulley 120 is arranged on the second connecting rod 115 and can rotate relative to the second connecting rod 115, and after being arranged, the first pulley 120 is accommodated in the groove formed by the first plate body 111, the second plate body 112 and the third plate body 113.

[0045] The first connecting rod 114 can be arranged in the support assembly 200 to make the connection between the adapter support 110 and the support assembly 200 more stable. For example, the first connecting rod 114 can be a screw rod, which is arranged in the screw hole of the support assembly 200 through the first connecting rod 114, so that the adapter support 110 and the support assembly 200 are detachably connected. The second connecting rod 115 can be divided into two parts along the axial direction thereof. The outer wall of the part away from the third plate body 113 can be provided with threads, and the outer wall of the part close to the third plate body 113 is not provided with threads. The first pulley 120 is arranged in the part not provided with threads, so that the first pulley 120 can rotate around the second connecting rod 115. When the pull rope 300 is pulled downward with the first pulley 120 as the fulcrum, the rotation of the first pulley 120 can reduce the friction loss of the pull rope 300. The threaded part of the second connecting rod 115 can be screwed into a nut to limit the axial sliding of the first pulley 120 along the second connecting rod 115, and prevent the first pulley 120 from being separated from the second connecting rod 115.

[0046] The second plate body 112 is provided with an avoiding groove 117, and the opening 132 of the avoiding groove 117 faces away from the training platform 400. The avoiding groove 117 can be a U-shaped groove, which is located corresponding to the side surface of the first pulley 120. After the pull rope 300 passes through the first pulley 120, it can extend to the outside of the adapter support 110 through the avoiding groove 117, so that the friction between the pull rope 300 and the second plate body 112 can be avoided through the avoiding groove 117. The avoiding groove 117 is located on the second plate body 112, and after the pull rope 300 passes out of the avoiding groove 117, it enters the through hole 131 of the universal sleeve 130.

[0047] The adapter support 110 includes a fixed plate 116 connected to the surface of the second plate body 112 away from the first plate body 111, and the fixed plate 116 is used to connect the universal sleeve 130. The shape of the fixed plate 116 can be similar to the shape of the outer side wall of the universal sleeve 130, so that when the universal sleeve 130 is placed on the fixed plate 116, it can be attached to the surface of the fixed plate 116, thereby improving the stability of the connection between the fixed plate 116 and the universal sleeve 130. For example, when the universal sleeve 130 is in the shape of a hollow cylinder, the fixed plate 116 can also be in the shape of an arc-shaped plate. The universal sleeve 130 and the fixed plate 116 can be connected by welding, threaded connection, rivet connection, etc.
