Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a Smith machine pressurized eccentric training device. Background Technology

[0002] The Smith machine fixes the barbell within steel rails, allowing it to move only vertically or near vertically. This design provides users with safe and stable training equipment, enabling them to confidently use heavy weights, making it particularly suitable for strength training enthusiasts and athletes. It also helps isolate specific muscle groups for targeted strength training and muscle building. Early Smith machines were simple barbell guide systems, but their technology has evolved with the development of the fitness industry and changing user needs. Modern Smith machines typically incorporate safety devices such as limiters and may be equipped with additional components like pull-up bars and rowing bars to expand their training capabilities. However, when using a Smith machine for targeted eccentric strength training like squats, while adding weight plates to the barbell can provide the necessary load stimulation, it can make it difficult for the user to stand up, potentially leading to accidents. Therefore, there is a need for a device that can effectively address these issues, providing sufficient training load during eccentric training without hindering the user's ability to stand up. Utility Model Content

[0003] To overcome the above-mentioned defects, the embodiments of this utility model provide a Smith machine pressure-assisted centrifugal trainer, which solves the technical problems of insufficient load and difficulty in standing up during resistance squat training in related technologies.

[0004] According to one aspect, at least one embodiment of the present invention provides a Smith machine pressurized assisted centrifugal trainer, including a frame and a barbell lifted and mounted on the frame, and further including an auxiliary pressurization assembly, the auxiliary pressurization assembly comprising: A limiting component is provided on the barbell; The counterweight is raised and lowered relative to the frame. After the counterweight is lowered, it can abut against the limiting member and increase the downward pressure of the limiting member. A drive unit, mounted on the frame, provides a force for the counterweight to rise, thereby reducing the pressure of the counterweight on the limiting member.

[0005] For example, at least one embodiment of this utility model provides a Smith machine pressurized centrifuge trainer, wherein the pressurization component further includes: A guide rod is mounted on the frame, with its axis perpendicular to the barbell axis. The counterweight is slidably mounted on the guide rod.

[0006] For example, at least one embodiment of this utility model provides a Smith machine pressurized centrifugal trainer, wherein the limiting member includes: The first set of rings is fitted onto the outer wall of the barbell; The second ring is fitted onto the outer wall of the guide rod, and the counterweight abuts against the second ring after it descends.

[0007] For example, at least one embodiment of the present invention provides a Smith machine pressurized centrifugal trainer, which further includes: A rope winder is located at the output end of the drive unit; The traction rope has its two ends respectively mounted on the rope winder and the counterweight. The driving component can drive the rope winder to wind the traction rope, thereby causing the counterweight to rise. The traction rope can be released freely when the counterweight descends.

[0008] For example, at least one embodiment of this utility model provides a Smith machine pressurized centrifugal trainer, wherein the counterweight includes: The third ring is fitted onto the outer wall of the guide rod and is connected to the traction rope. The bottom of the third ring has a receiving platform. A counterweight block is provided on the receiving platform to provide counterweight.

[0009] For example, at least one embodiment of this utility model provides a Smith machine pressurized centrifugal trainer, wherein the counterweight is sleeved on the outer wall of the third ring, the counterweight includes an annular block and a limiting block, the annular block has a dovetail notch, the dovetail notch allows the third ring to pass radially, the limiting block is located at the dovetail notch, the limiting block can restrict the annular block from moving radially along the third ring.

[0010] For example, at least one embodiment of this utility model provides a Smith machine pressurized centrifugal trainer, wherein the pressurization auxiliary assembly has two sets, which are located at both ends of the frame respectively.

[0011] For example, at least one embodiment of this utility model provides a Smith machine-assisted centrifugal trainer, wherein the frame has a guide slide, the barbell moves up and down along the guide slide, and further includes: The stop bar has two sets, each set having several bars. The two sets of stop bars are respectively set at both ends of the frame, and the stop bars in each set are spaced apart along the vertical direction. The locking mechanism has two latches, which are rotatably mounted on the barbell and located at both ends of the frame. After the latches are rotated, they can lock with the stop bar to restrict the descent of the barbell.

[0012] The beneficial effects of this utility model are as follows: In this invention, by incorporating an auxiliary pressure-applying component, during the squatting phase, the counterweight contacts the limiting component, and its weight is superimposed on the barbell, increasing the downward pressure on the barbell and satisfying the load stimulation required for eccentric training. During the standing phase, the drive component provides the upward force for the counterweight, reducing the pressure of the counterweight on the limiting component, thereby reducing the downward pressure on the barbell and decreasing the force the trainee needs to overcome when standing up, thus avoiding difficulty in standing. The limiting component is located on the barbell to ensure that the pressure of the counterweight is directly transmitted to the barbell, guaranteeing the effectiveness of the pressure application. The counterweight is raised and lowered relative to the frame, allowing it to contact the limiting component under gravity or disengage under the action of the drive component, thus increasing or decreasing the pressure. The drive component is located on the frame to provide the upward force for the counterweight. By changing the pressure of the counterweight on the limiting component, the downward pressure on the barbell is adjusted, enabling the device to meet the training load while solving the problem of difficulty in standing up and reducing the occurrence of safety accidents.

[0020] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Studies have shown that a normal human body can withstand 30%-50% more load during the squatting phase (eccentric phase) than during the standing phase (concentric phase). However, the load intensity of conventional training is designed based on a percentage of maximum concentric force, resulting in insufficient stimulation of eccentric force in conventional strength training. Eccentric force is a key factor in increasing jump height and improving explosive power performance, such as the ability to quickly change direction. Therefore, a Smith machine-assisted pressure eccentric training device was designed to address the insufficient load stimulation during the eccentric phase of conventional training, increasing the convenience, continuity, and safety of targeted eccentric training.

[0022] like Figures 1-5 As shown, this invention illustrates a Smith machine-assisted centrifugal trainer according to one embodiment of the present invention. It includes a frame 1 with a guide structure extending vertically, and a barbell 2 capable of rising and falling along the guide structure. A limiting member 31 is fixedly disposed on the side of the barbell 2, extending radially outward. A counterweight 32 is disposed on the frame 1, above the limiting member 31, and slidably disposed on the frame 1, allowing the counterweight 32 to rise and fall vertically relative to the frame 1. A driving member 33 is fixedly mounted on the top of the frame 1, and its output end is connected to the counterweight 32, enabling it to drive the counterweight 32 to rise or fall, thereby changing the pressure applied to the barbell 2.

[0023] The counterweight 32 increases the pressure during the downward press of the barbell, and the drive component 33 drives the counterweight 32 upward, reducing the load when standing up. This provides the trainee with additional eccentric load while reducing the actual problem of difficulty standing up due to excessive load. Specifically, by setting up the auxiliary pressure component 3, during the trainee's squatting phase, the counterweight 32 abuts against the limiting component 31, and its weight is superimposed on the barbell 2, increasing the downward pressure on the barbell 2 and meeting the load stimulation required for resistance training. During the trainee's standing up phase, the drive component 33 provides the upward force of the counterweight 32, reducing the pressure of the counterweight 32 on the limiting component 31, thereby reducing the downward pressure on the barbell 2, reducing the force that the trainee needs to overcome when standing up, and avoiding difficulty in standing up. The weight of the counterweight 32 can be adjusted according to actual use. The limiting component 31 is set on the barbell 2 to ensure that the pressure of the counterweight 32 can be directly transmitted to the barbell 2, ensuring the effectiveness of the pressure effect. The counterweight 32 is vertically oriented relative to the frame 1, allowing it to contact the limiting member 31 under gravity or disengage under the action of the driving member 33, thus increasing or decreasing the pressure. The driving member 33, mounted on the frame 1, provides the upward force for the counterweight 32. By changing the pressure of the counterweight 32 on the limiting member 31, the downward pressure on the barbell 2 is adjusted, enabling the device to meet training load requirements while addressing the difficulty of standing up and reducing the occurrence of safety accidents.

[0024] like Figure 1As shown, a guide rod 34 is fixedly installed on the frame 1. The axis of the guide rod 34 is perpendicular to the axis of the barbell 2, and the guide rod 34 extends horizontally. A through hole is provided on the counterweight 32, through which the guide rod 34 passes, allowing the counterweight 32 and the guide rod 34 to slide together. The counterweight 32 can slide along the axis of the guide rod 34 and simultaneously rise and fall vertically relative to the frame 1. The guide rod 34 makes the rising and falling motion of the counterweight 32 more stable, preventing the counterweight 32 from shifting during the rising and falling process and ensuring that the counterweight 32 accurately abuts against the limiting member 31. Preferably, the guide rod 34 is used as the guide for the counterweight 32; alternatively, a guide rail or other structure capable of providing guidance can also be used.

[0025] like Figure 2 As shown, the limiting member 31 includes a first ring 311 and a second ring 312. The first ring 311 is fitted onto the outer wall of the barbell 2 and is fixedly connected to the barbell 2. The second ring 312 is fitted onto the outer wall of the guide rod 34 and is fixedly connected to the first ring 311. The second ring 312 is located below the counterweight 32. The limiting member 31 can move up and down with the barbell 2, and the barbell 2 can abut against the counterweight 32 when it rises to its highest position.

[0026] like Figure 5 As shown, the output end of the drive unit 33 is connected to the rope winder 35, and a traction rope 36 is wound on the rope winder 35. One end of the traction rope 36 is fixedly connected to the rope winder 35, and the other end is fixedly connected to the counterweight 32. When the counterweight 32 descends, the traction rope 36 is released freely from the rope winder 35; when the drive unit 33 drives the rope winder 35 to rotate, the traction rope 36 winds around the rope winder 35, causing the counterweight 32 to rise. The first ring 311 is fixed to the barbell 2, and the second ring 312 cooperates with the guide rod 34, so that the limiting member 31 is simultaneously connected to both the barbell 2 and the guide rod 34, enhancing the stability of the limiting member 31 and ensuring that the pressure of the counterweight 32 can be stably transmitted to the barbell 2. The drive unit 33 is equipped with a sensor that can sense the torque between the rope reel 35 and the drive unit 33. When the trainee stands up and the barbell 2 reaches the highest position, the limiting member 31 abuts against the counterweight 32. The counterweight 32 is partially supported by the limiting member 31, reducing the tension of the traction rope 36 in the rope reel 35, thereby reducing the torque between the drive unit 33 and the rope reel 35. The sensor detects the torque reduction signal and causes the drive unit 33 to release the counterweight 32, so that the force of the counterweight 32 is applied to the barbell 2. The trainee performs a squatting exercise. During the squatting process, the traction rope 36 is in a slack state. When the trainee descends to the lowest position, the rope tightens, and the torque between the drive unit 33 and the rope reel 35 increases. The sensor detects the torque increase signal and causes the drive unit 33 to pull up the counterweight 32. The length of the traction rope 36 released by the rope reel 35 can be adjusted according to the different positions of the trainee's highest and lowest points.

[0027] like Figures 2-3 As shown, the counterweight 32 includes a third ring 321 and a counterweight block 322. The third ring 321 is sleeved on the outer wall of the guide rod 34 and forms a sliding fit with the guide rod 34. The third ring 321 is connected to the end of the traction rope 36 away from the rope winder 35. The bottom of the third ring 321 is provided with a receiving platform 3211. The receiving platform 3211 extends outward along the radial direction of the third ring 321. The counterweight block 322 is placed on the receiving platform 3211. The counterweight 322 includes an annular block 3221 and a limiting block 3222. One side of the annular block 3221 has a dovetail notch 3223, the size of which allows the third ring 321 to pass radially. The limiting block 3222 is located at the dovetail notch 3223 and is detachably connected to the annular block 3221. When the limiting block 3222 is installed at the dovetail notch 3223, it restricts the radial movement of the annular block 3221 along the third ring 321. The cooperation between the rope winder 35 and the traction rope 36 enables the indirect driving of the counterweight 32 by the driving component 33. The rotation of the rope winder 35 controls the winding and unwinding of the traction rope 36, thereby controlling the lifting and lowering of the counterweight 32, allowing the driving force of the driving component 33 to act more smoothly on the counterweight 32. The third ring 321 cooperates with the guide rod 34 to ensure the stability of the lifting direction of the counterweight 32. The receiving platform 3211 provides support for the counterweight block 322, allowing the counterweight block 322 to be stably placed on the third ring 321. The dovetail notch 3223 of the ring block 3221 is designed to facilitate the radial installation of the counterweight block 322 onto the third ring 321, while the limiting block 3222 prevents the counterweight block 322 from detaching radially from the third ring 321 during movement, ensuring the connection stability between the counterweight block 322 and the third ring 321.

[0028] like Figures 1-5 As shown, there are two sets of auxiliary pressure components 3, located at both ends of the frame 1. The guide rod 34, limiter 31, counterweight 32, drive component 33, rope winder 35, and traction rope 36 in each set of auxiliary pressure components 3 are arranged in the same way. The two sets of auxiliary pressure components 3, located at both ends of the frame 1, ensure more even pressure on both ends of the barbell 2, preventing the barbell 2 from tilting due to uneven force and guaranteeing stability during training.

[0029] like Figures 1-5As shown, the frame 1 is equipped with a guide slide 11. The two ends of the barbell 2 are located within the guide slide 11, forming a sliding engagement with it, allowing the barbell 2 to rise and fall along the guide slide 11. Two sets of stop levers 12 are provided at each end of the frame 1, each set of stop levers 12 spaced vertically at equal intervals. Locks 13 are provided at both ends of the barbell 2, and are rotatably connected to the barbell 2 via a pivot. The locks 13 can rotate around the pivot, and when they rotate to contact the stop levers 12, they form a locking engagement, restricting the descent of the barbell 2. The guide slide 11 provides guidance for the rise and fall of the barbell 2, ensuring that the barbell 2 moves in a predetermined direction. The engagement of the stop levers 12 and the locks 13 allows the barbell 2 to lock at different heights, preventing accidental descent and increasing safety during training.
