[0052] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0053] The weightlifting bed for sports training disclosed in this invention is mainly used in situations where the usage method and safety protection device are relatively simple. When using it, trainees may use a sitting posture to lift weights due to a lack of understanding, which makes it difficult for the safety protection device to play a protective role and may cause injury to the trainees.

[0054] Reference Figures 1-8 A weightlifting bench for sports training, comprising:

[0055] A bed frame 1 is provided on the bed frame 1, and a bed body 3 is provided on the bed body 3. Multiple rectangular openings 4 are provided on the bed body 3.

[0056] Two lifting arms 5 are mounted on the bed frame 1, and each of the two lifting arms 5 is equipped with a lifting handle 8.

[0057] The sitting posture stop unit 6 is installed on the bed frame 1 and is used for the stop protection of trainees during sitting posture training.

[0058] Two barbell plate disassembly and assembly modules 2 are respectively set on the two lifting arms 5. The barbell plate disassembly and assembly modules 2 are used for quick disassembly and assembly of barbell plates.

[0059] The bed frame quick-drying module 7 is installed on the bed frame support 1. The bed frame quick-drying module 7 is used for quick-drying treatment of the bed body 3 to avoid slipping and cross-infection.

[0060] Reference Figures 1-5 In a preferred embodiment, the seated posture arresting unit 6 includes:

[0061] The crossbar body 603 is mounted on the bed frame 1 and has a through fixing port 606.

[0062] The movable frame 605 is set on the crossbar body 603. The movable frame 605 has a locking interface 609 and foot push rods 604 are provided on both outer walls of the movable frame 605.

[0063] The snap-fit ​​component 608 is located inside the fixing port 606 and has a reset pull rope 610 that passes through the fixing port 606.

[0064] In this invention, the seated posture arresting unit 6 further includes:

[0065] Two vertical supports 601 are provided on the bed frame support 1, and two guide wheels 619 are provided on each of the two vertical supports 601.

[0066] Two connecting cables 607 are respectively installed on two guide wheels 619. The outer walls of the two connecting cables 607 are in contact with the inner walls of the other two guide wheels 619. One end of the two connecting cables 607 is fixedly connected to the top of the two lifting arms 5.

[0067] In this invention, the sitting posture arresting unit 6 further includes:

[0068] Four mounting collars 620 are respectively mounted on two of the guide wheels 619;

[0069] Four fixing rings 622 are respectively set on two vertical supports 601. Each of the four fixing rings 622 is equipped with a spring 621. One end of each spring 621 is fixedly connected to the inner wall of the four mounting rings 620.

[0070] In this invention, the seated posture arresting unit 6 further includes:

[0071] Two horizontal supports 602 are provided on the bed frame support 1 and two vertical supports 601. Each of the two horizontal supports 602 is provided with a driven frame 614, and each of the two driven frames 614 is provided with two mounting parts 616.

[0072] Two connecting rod frames 611 are provided on the movable sleeve frame 605. One end of each connecting rod frame 611 is provided with a follower frame 613. The two follower frames 613 are respectively provided on two horizontal supports 602.

[0073] In this invention, the seated posture arresting unit 6 further includes:

[0074] Two guide rollers 618 are respectively mounted on two transverse supports 602. Two connecting cables 617 are mounted on each of the two follower frames 613. The outer walls of the four connecting cables 617 are in contact with the inner walls of the two guide rollers 618 respectively. One end of the four connecting cables 617 is fixedly connected to one side of the outer wall of the four mounting parts 616 respectively.

[0075] Four return spring rods 615 are respectively set on two vertical supports 601, and one end of each of the four return spring rods 615 is respectively set on two driven frames 614;

[0076] Four stop clamps 612 are respectively disposed on two follower frames 613 and two driven frames 614.

[0077] Specifically, during seated training, the lifting arm 5 rises to move the connecting cable 607. At this time, the spring 621 can drive two of the guide wheels 619 to wind up, so as to tighten the connecting cable 607 and prevent it from becoming too loose.

[0078] During the training stop, the trainee triggers the foot push rod 604 with their foot, causing the movable sleeve 605 to move on the crossbar body 603 until the locking piece 608 engages with the locking interface 609 on the movable sleeve 605. During this process, the movable sleeve 605 can drive the connecting rod frame 611 to move, so that the follower frame 613 moves on the transverse support 602. At this time, the movement of the follower frame 613 can pull the connecting cable 617, and through the connecting cable 617, drive the driven frame 614 to move on the transverse support 602, so that the driven frame 614 and the follower frame 613 gradually approach each other, and the stopping clamp 612 stops and clamps the connecting cable 607 to complete the stopping of the weight-bearing part.

[0079] In specific application scenarios, the seated stop unit 6 is suitable for use in weightlifting bench training. When in use, the seated stop unit 6 can increase the training posture of the weightlifting bench, adding a seated usage mode to the bench press to enhance the effectiveness of the device. At the same time, when the trainee is training in a seated position, the device can be stopped and locked with the feet when the trainee is weak, so as to stop the weight-bearing part and prevent it from falling and causing injury to the trainee, thereby increasing the safety of the device.

[0080] It should be noted that when the lifting arm 5 rises, the spring 621 can automatically wind up the connecting cable 607 to prevent the connecting cable 607 from becoming excessively loose.

[0081] The reset pull cord 610 can separate the locking member 608 from the locking interface 609 after the device is stopped, thereby resetting the weight-bearing part.

[0082] Reference Figure 1 , Figure 6 and Figure 7 In a preferred embodiment, the barbell plate assembly / disassembly module 2 includes:

[0083] The disassembly and assembly rod 201 is installed on the lifting arm 5. The disassembly and assembly rod 201 has four installation ports 202 and two locking baffles 205 are provided inside the disassembly and assembly rod 201.

[0084] The telescopic spring 210 is located inside the detachable rod 201. One end of the telescopic spring 210 is provided with a mounting rod 208, and one end of the mounting rod 208 is provided with a rotating gripping roller 204.

[0085] Four locking slots 207 are provided on the rotating gripping roller 204, and two of the locking slots 207 are engaged with two locking baffles 205.

[0086] In this invention, the barbell plate assembly / disassembly module 2 further includes:

[0087] Four elastic limiting members 203 are provided on the disassembly and assembly rod 201. Each of the four elastic limiting members 203 is provided with a linkage rod 206. The four linkage rods 206 pass through the four mounting ports 202 respectively.

[0088] Four fasteners 209 are provided on the mounting rods 208, and one end of each of the four linkage rods 206 is provided on one of the four fasteners 209.

[0089] Specifically, when assembling or disassembling the barbell plates, rotate the grip roller 204 to separate the locking groove 207 from the locking baffle 205. Then, push the grip roller 204 to move the mounting rod 208 and compress the telescopic spring 210. As the mounting rod 208 moves, the linkage rod 206 on the fixing member 209 moves accordingly and pulls the elastic limiting member 203, causing the elastic limiting member 203 to deform and gradually fit against the outer wall of the disassembly / assembly rod 201. Then, rotate the grip roller 204 again to engage the other two locking grooves 207 with the locking baffle 205 to facilitate the assembly or disassembly of the barbell plates.

[0090] After the barbell plates are disassembled and assembled, rotating the grip roller 204 causes the other two locking slots 207 to separate from the locking baffle 205. Under the action of the telescopic spring 210, the elastic limiting member 203, the mounting rod 208 and the rotating grip roller 204 are reset. After the reset, rotating the grip roller 204 again causes the two original locking slots 207 to engage with the locking baffle 205 (which can prevent the barbell plates from falling off after installation).

[0091] In specific application scenarios, the barbell plate disassembly and assembly module 2 is suitable for the disassembly and installation of barbell plates. That is, when using the barbell plate disassembly and assembly module 2, it makes it easier for trainees to disassemble and assemble barbell plates. It allows the barbell plates to be quickly detached during disassembly, thereby reducing the difficulty of disassembly. At the same time, it can block the barbell plates during installation to ensure their installation stability and prevent them from falling off during training, thereby further increasing the effectiveness and safety of the device.

[0092] It should be noted that during disassembly and assembly, the locking groove 207 can engage with the locking baffle 205 to lock the posture of the elastic limiting member 203, further facilitating disassembly and assembly operations.

[0093] Reference Figure 2 and Figure 8 In a preferred embodiment, the bed quick-drying module 7 includes:

[0094] Two linear guide rails 701 are mounted on the bed frame 1 and located below the bed body 3. Each linear guide rail 701 is equipped with a guide rail slider 702.

[0095] A fixed frame 708 is mounted on two guide rail sliders 702.

[0096] In this invention, the bed quick-drying module 7 further includes:

[0097] Fan component 707 is mounted on fixed frame 708 and is located below bed body 3;

[0098] A sealing base plate 704 is provided at the bottom of the fixed frame 708. Two elastic air tubes 703 are provided on the sealing base plate 704, and one end of the two elastic air tubes 703 is provided with the same air outlet 705.

[0099] Tie rod 706 is mounted on fixed frame 708.

[0100] Specifically, when sweat stains are drying quickly, the fan 707 operates so that airflow passes through the surface of the bed body 3 and enters the rectangular opening 4. The airflow is then transported by the fan 707 to the interior of the elastic air tube 703. The air is then ejected again through the elastic air tube 703 and the air outlet 705 to blow on the surface of the bed body 3, thereby further increasing the drying efficiency. At the same time, when drying quickly, the pull rod 706 can be pulled according to the actual amount of sweat stains. The pull rod 706 can also pull the fixed frame 708 and the guide rail slider 702 to change the drying position.

[0101] In specific application scenarios, the bed quick-drying module 7 is suitable for the quick-drying stage of the bed body 3. That is, when the bed quick-drying module 7 is in use, it can increase the gas flow rate at the rectangular opening 4 on the bed body 3, so that the airflow can flow over the surface of the bed body 3, thereby increasing the drying rate of the bed. At the same time, the device can return the airflow to the surface of the bed body 3 through the elastic air tube 703 and the airflow opening 705 to further increase the drying rate. This allows the device to quickly dry the bed body 3 during use, avoiding sweat residue that could cause slippage and cross-infection.

[0102] It should be noted that the quick-drying position of the device can be adjusted via the pull rod 706 during use to adapt to the quick-drying treatment of sweat stains for different people.

[0103] Working principle:

[0104] When assembling or disassembling the barbell plates, rotate the grip roller 204 to separate the locking groove 207 from the locking baffle 205. Then push the grip roller 204 to move the mounting rod 208 and compress the telescopic spring 210. As the mounting rod 208 moves, the linkage rod 206 on the fixing member 209 moves and pulls the elastic limiting member 203, causing the elastic limiting member 203 to deform and gradually fit against the outer wall of the disassembly / assembly rod 201. Then rotate the grip roller 204 again to engage the other two locking grooves 207 with the locking baffle 205 to facilitate the assembly or disassembly of the barbell plates.

[0105] After the barbell plates are disassembled and assembled, rotating the grip roller 204 causes the other two locking slots 207 to separate from the locking baffle 205. Under the action of the telescopic spring 210, the elastic limiter 203, the mounting rod 208 and the rotating grip roller 204 are reset. After the reset, rotating the grip roller 204 again causes the two original locking slots 207 to engage with the locking baffle 205.

[0106] During seated training, the lifting arm 5 rises to move the connecting cable 607. At this time, the spring 621 can drive two of the guide wheels 619 to wind up, so as to tighten the connecting cable 607 and prevent it from becoming too loose.

[0107] During the training stop, the trainee triggers the foot push rod 604 with their foot, causing the movable sleeve 605 to move on the crossbar body 603 until the locking piece 608 engages with the locking interface 609 on the movable sleeve 605. During this process, the movable sleeve 605 can drive the connecting rod frame 611 to move, so that the follower frame 613 moves on the transverse support 602. At this time, the movement of the follower frame 613 can pull the connecting cable 617, and through the connecting cable 617, drive the driven frame 614 to move on the transverse support 602, so that the driven frame 614 and the follower frame 613 gradually approach each other, and the stopping clamp 612 stops and clamps the connecting cable 607 to complete the stopping of the weight-bearing part.

[0108] When sweat dries quickly, the fan 707 operates, allowing airflow to pass through the surface of the bed body 3 and enter the rectangular opening 4. The airflow is then transported by the fan 707 to the interior of the elastic air tube 703. The air is then ejected again through the elastic air tube 703 and the air outlet 705, blowing on the surface of the bed body 3 to further increase the drying efficiency. Simultaneously, during the quick-drying process, the pull rod 706 can be pulled according to the actual amount of sweat, and the pull rod 706 can pull the fixed frame 708 and the guide rail slider 702 to change the quick-drying position.

[0109] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
