[0031] See also Figures 1 to 4 The utility model proposes a bench press with a protective function, comprising: a bench press frame 1, a barbell assembly 2, a fall arrester 3, a lifting drive assembly 5 and a switch 6; the switch 6, the barbell assembly 2, the fall arrester 3 and the lifting drive assembly 5 are sequentially installed on the bench press frame 1 along the height direction of the bench press frame 1, the fall arrester 3 and the lifting drive assembly 5 are both transmission-connected to the barbell assembly 2, and the lifting drive assembly 5 is controlled by the switch 6.

[0032] In actual use, when the trainee reaches the limit of strength and the barbell assembly 2 starts to fall rapidly, the fall arrester 3 immediately activates its built-in braking system to prevent the barbell assembly 2 from falling freely. Then the trainee presses the switch 6, and the lifting drive assembly 5 lifts the barbell assembly 2 to a safe position, so that the trainee can safely leave the bench press rack 1.

[0033] In another embodiment, an acceleration sensor is provided on the barbell assembly 2. When the acceleration sensor detects that the barbell assembly 2 suddenly loses weight, the acceleration sensor sends a signal to the anti-fall device 3 and the lifting drive assembly 5. After receiving the command, the anti-fall device 3 immediately activates its built-in braking system to prevent the barbell assembly 2 from falling freely. After receiving the command, the lifting drive assembly 5 lifts the barbell assembly 2 from the current position to a safe position, so that the trainee can safely leave the bench press rack 1.

[0034] The bench press with protective function proposed in this embodiment prevents the trainee from being injured by the barbell assembly 2 falling out of his hands due to his strength limit without the assistance of a coach through the mutual cooperation of the fall arrester 3 and the lifting drive assembly 5, thereby improving the safety of bench press training.

[0035] See also Figures 2 to 4 The barbell assembly 2 includes a barbell rod 21 and sliding seats 22 respectively connected to both ends of the barbell rod 21, and the sliding seats 22 are connected to the anti-fall device 3 and the lifting drive assembly 5.

[0036] Specifically, when the barbell assembly 2 begins to fall due to insufficient strength of the trainee, the anti-fall device 3 locks the sliding seat 22, thereby preventing the barbell assembly 2 from falling. When the trainee presses the switch 6 to start the lifting drive assembly 5, the lifting drive assembly 5 drives the sliding seat 22 to rise along the height direction of the bench press rack 1, lifting the barbell assembly 2 from its current position to a safe position.

[0037] See also Figure 4 The barbell assembly 2 also includes a gear 23, which is connected to the sliding seat 22. The bench press frame 1 is provided with a serrated plate 12 corresponding to the gear 23, and the gear 23 is meshed with the serrated plate 12.

[0038] Specifically, when the trainee performs bench press training, the barbell bar 21 drives the sliding seat 22 to move up and down, and the gear 23 on the sliding seat 22 engages with the serrated plate 12 on the bench press frame 1, preventing the barbell bar 21 from lateral deviation or shaking during the up and down movement, thereby improving the straightness and stability of the barbell bar 21 during the movement. When the trainee presses the switch 6 to start the lifting drive assembly 5, the lifting drive assembly 5 drives the sliding seat 22 to rise smoothly along the length direction of the serrated plate 12, lifting the barbell assembly 2 from its current position to a safe position.

[0039] See also Figure 2 The bench press frame 1 is provided with a guide rod 11 , the two ends of the guide rod 11 are respectively connected to the top and bottom ends of the bench press frame 1 , and the sliding seat 22 slides on the rod body of the guide rod 11 .

[0040] Specifically, when the trainee pushes the barbell assembly 2 to perform bench press training or the lifting drive assembly 5 drives the barbell assembly 2 to lift, the sliding seat 22 slides on the rod body of the guide rod 11, so that the barbell assembly 2 can maintain linear motion during the up and down movement, avoiding the barbell assembly 2 from moving horizontally. At the same time, the trainee's training movements can be corrected to improve the trainee's training quality.

[0041] See also Figures 2 to 3 The lifting drive assembly 5 includes: a driving motor 51, a reducer 52 and a transmission rod 53. The driving motor 51 is connected to the bench press frame 1. The driving motor 51 is controlled by the switch 6. The reducer 52 is connected to the driving motor 51 in a transmission connection. The reducer 52 is connected to the transmission rod 53 in a transmission connection. The transmission rod 53 is connected to the sliding seat 22 in a transmission connection.

[0042] Specifically, the two ends of the transmission rod 53 are respectively connected to the sliding seats 22 at the two ends of the barbell bar 21, so that the barbell assembly 2 is driven by the drive motor 51. When the trainee presses the switch 6 to start the lifting drive assembly 5, the drive motor 51 begins to output power. The power is reduced in speed by the reducer 52 and then torque-increased before being transmitted to the transmission rod 53. After receiving the power, the transmission rod 53 drives the sliding seat 22 to move on the guide rod 11, thereby driving the barbell assembly 2 to move up and down.

[0043] See also Figure 2 The lifting drive assembly 5 also includes a pull rope 54 , one end of the pull rope 54 is connected to the transmission rod 53 , and the other end of the pull rope 54 is connected to the sliding seat 22 .

[0044] Specifically, one end of the pull rope 54 is fixed to the transmission rod 53 through a clamp. When the transmission rod 53 is driven by the driving motor 51 to rotate, the pull rope 54 will also be wound up, so that the barbell assembly 2 rises.

[0045] In this embodiment, the pull rope 54 is made of nylon. Nylon has the advantages of high strength, wear resistance, corrosion resistance, flexibility and low friction. The use of the nylon pull rope 54 in conjunction with the transmission rod 53 and the sliding seat 22 improves the safety of the trainee during a single bench press training.

[0046] See also Figures 1 to 3 The connecting end of the anti-fall device 3 is connected to the bench press frame 1, and the braking end of the anti-fall device 3 is connected to the sliding seat 22.

[0047] Specifically, the connecting end of the fall arrester 3 is connected to the bench press frame 1 by bolts, and the braking end of the fall arrester 3 is connected to the sliding seat 22 by pins. When the trainee reaches the limit of strength, causing the barbell assembly 2 to fall rapidly, the fall arrester 3 locks the sliding seat 22, thereby preventing the barbell bar 21 from falling and preventing the barbell assembly 2 from hitting the trainee.

[0048] Please refer again Figures 1 to 3 The bench press with protective function also includes a steel wire rope 4, one end of the steel wire rope 4 is connected to the sliding seat 22, and the other end of the steel wire rope 4 is connected to the braking end of the anti-fall device 3.

[0049] Specifically, the steel wire rope 4 has high strength and toughness, and can withstand large tensile and impact forces. The steel wire rope 4 connects the braking end of the fall arrester 3 to the sliding seat 22, ensuring that the rope connecting the fall arrester 3 and the sliding seat 22 will not break due to excessive force during emergency braking, thereby improving the safety of the bench press.

[0050] See also Figure 1 The bench press with protective function also includes a dust cover 7, which is arranged on the lifting drive component 5.

[0051] Specifically, the dust cover 7 is provided on the lifting drive assembly 5, which can prevent dust and other impurities from entering the interior of the lifting drive assembly 5, so that the lifting drive assembly 5 can operate stably, while preventing dust and other impurities from corroding the lifting drive assembly 5, thereby improving the service life of the lifting drive assembly 5.

[0052] Compared with the existing technology, the bench press with protective function proposed in the present invention, through the mutual cooperation of the fall arrester 3 and the lifting drive assembly 5, avoids the phenomenon that the trainee is injured by the barbell assembly 2 falling out of his hand due to the limit of his strength without the assistance of a coach, thereby improving the safety of bench press training.

[0053] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
