[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] like Figure 1 - Figure 4 As shown, this embodiment provides a technical solution: a leg press training safety protection device, comprising a leg press training device body 1, a connecting bracket 7 is arranged on the top of the leg press training device body 1, a track cross bar 2 is arranged on the connecting bracket 7, a protection component 3 is arranged on the track cross bar 2, and an anti-fall component 5 is arranged on the protection component 3;

[0029] The anti-falling component 5 includes an outer ring 51, a stopper 52 is arranged on the inner side of the outer ring 51, a fixing plate 513 is arranged on the inner side of the outer ring 51, a telescopic rod 53 is arranged on the fixing plate 513, a connecting shaft 54 ​​is arranged on one side of the telescopic rod 53, a connecting rod 2 55 is arranged on the other end of the connecting shaft 54, a connecting rod 3 56 is arranged on the other end of the connecting rod 2 55, a rotating shaft 2 58 is arranged on the other end of the connecting rod 3 56, and a braking hook 57 is arranged on the other end of the rotating shaft 2 58. When the user loses strength for some reason and cannot control the descending speed of the equipment, the equipment will slide down rapidly due to the action of gravity, and this rapid sliding action will be directly transmitted to the gear 1 510, causing it to rotate rapidly. Since the gear 1 510 is connected to the fixing plate 513, its The rotation will drive the fixed plate 513 to rotate at high speed. The rotation of the fixed plate 513 will then transmit power to the braking system through the connecting shaft 54 ​​and the connecting rod 2 55, causing the entire braking mechanism to start to operate. During this operation, the brake hook 57 rotates around the rotating shaft 2 58. It is designed to automatically or be triggered to swing outward when the equipment slides down too fast, so that the outer part of the brake hook 57 hooks the preset block 52 on the outer ring 51. When the brake hook 57 successfully hooks the block 52, it will generate a braking force on the track crossbar 2. This force is sufficient to counteract the sliding power of the equipment due to gravity, thereby achieving the effect of emergency braking and solving the technical problem of the equipment causing harm to the user after the user is detached.

[0030] Further, such as Figure 2 and Figure 3 As shown: a toothed ring 59 is provided on the inner side of the fixed plate 513, a gear 1 510 is provided on the inner side of the toothed ring 59, a gear 2 511 is provided between the gear 1 510, and a connecting column 512 is provided on the inner side of the gear 2 511. When the outer ring 51 rotates, the action will be directly transmitted to the fixed plate 513 connected thereto, causing the fixed plate 513 to rotate accordingly, and this rotational motion is then transmitted to the gear 1 510. Since the gear 1 510 is meshed with the gear 2 511, the rotation of the gear 1 510 will drive the gear 2 511 to rotate together. This series mechanical transmission converts and transmits power through the connecting column 512, and finally realizes the fixation of the anti-fall component 5 inside the protective component 3. Such a design ensures the stability of the anti-fall system during the operation of the equipment.

[0031] When the above solution is still in use, using the automatic anti-falling component 5 alone will still cause danger to the user, such as Figure 5As shown: the handbrake assembly 4 includes a collar 41, a rotating shaft 42 is provided at the bottom of the collar 41, a speed reduction block 43 is provided on one side of the collar 41 away from the rotating shaft 42, a fixing block 44 is provided on the top of the collar 41, a steel wire rope 45 is provided on the fixing block 44, a support rod 46 is provided at one end of the steel wire rope 45, a fixing ring 47 is sleeved on the support rod 46, a connecting block 49 is provided on the fixing ring 47, a handle 48 is provided at one end of the connecting block 49, a steel wire rope 45 is provided at the other end of the connecting block 49, a connecting rod 411 is provided at the other end of the support rod 46, a rotating shaft 410 is provided inside the connecting rod 411, and the support rod 46 plays an important supporting role in the equipment, which ensures that the fixing ring 47 remains stable, providing a solid foundation for subsequent operations, and the user can easily pull the handle 48 by pressing the handle 48. The steel wire rope 45 connected to it is moved, and this action activates the handbrake assembly 4 of the equipment, so that the sliding speed of the equipment on the track cross bar 2 can be reduced. The rotating shaft 410 on the connecting rod 411 is cleverly designed, which allows the handle 48 to be more smooth and unobstructed when pulling the steel wire rope 45. As the steel wire rope 45 is pulled up, the fixed block 44 on the top of the ring 41 applies pressure to the ring 41, thereby achieving an automatic locking effect. This design cleverly utilizes mechanical advantages to convert manual pulling force into a stronger locking force. Subsequently, the rotation of the rotating shaft drives the ring 41 to squeeze inward, and further clamps the track cross bar 2 through the speed reduction block 43 on the inside of the ring 41. This clamping action directly causes the equipment to decelerate, because the friction between the speed reduction block 43 and the track cross bar 2 is significantly increased, thereby effectively slowing down the descent speed of the equipment.

[0032] Working principle:

[0033] like Figure 1 - Figure 5 As shown:

[0034] When in use: the user first climbs onto the device via the pedal 18 connected to the top of the bracket 7, and sits on the seat 10 supported by the support plate 2 12, and then places the legs on the pedal 2 9 and exerts force through the legs to drive the protection component 3 to drive the seat 10 to slide along the track crossbar 2 toward the support frame 2 13 through the reaction force, thereby playing the role of leg-pushing training, and the support frame 1 6 supports the support plate 11 and the device, thereby stabilizing the device. When the user loses strength for some reason and cannot control the descending speed of the device, the device will slide down rapidly due to the action of gravity, and this rapid sliding action will directly transmit the sliding shaft 32 in the baffle plate 31 to the gear 1 510, causing it to rotate rapidly. Since the gear 1 510 is connected to the fixed plate 5 13 is connected, and its rotation will drive the fixing plate 513 to rotate at a high speed. The rotation of the fixing plate 513 then transmits power to the braking system through the connecting shaft 54 ​​and the connecting rod 2 55, so that the entire braking mechanism starts to act. During this action, the braking hook 57 rotates around the rotating shaft 2 58. It is designed that when the equipment slides down too fast, it can automatically or be triggered to swing outward, so that the outer part of the braking hook 57 hooks the preset block 52 on the outer ring 51. When the braking hook 57 successfully hooks the block 52, it will generate a braking force on the track crossbar 2. This force is enough to counteract the sliding power generated by the gravity of the equipment, thereby achieving the effect of emergency braking. When the outer ring 51 rotates, the action is directly transmitted to the connecting rod 55 connected thereto. The fixed plate 513 connected to the gear 1 causes the fixed plate 513 to rotate, and this rotational movement is then transmitted to the gear 1 510. Since the gear 1 510 is meshed with the gear 2 511, the rotation of the gear 1 510 will drive the gear 2 511 to rotate together. This series mechanical transmission converts and transmits power through the connecting column 512 to finally achieve the fixation of the anti-fall component 5 inside the protective component 3. This design ensures the stability of the anti-fall system during the operation of the equipment. When in use, using the automatic anti-fall component 5 alone will still be dangerous to the user. The support rod 46 plays an important supporting role in the equipment. It ensures that the fixing ring 47 remains stable, providing a solid foundation for subsequent operations. The user can easily pull it by pressing the handle 48. The connected wire rope 45, this action activates the handbrake assembly 4 of the equipment, so that the sliding speed of the equipment on the track crossbar 2 can be reduced. The rotating shaft 410 on the connecting rod 411 is cleverly designed, which allows the handle 48 to be more smooth and unobstructed when pulling the wire rope 45. As the wire rope 45 is pulled up, the fixed block 44 on the top of the ring 41 applies pressure to the ring 41, achieving an automatic locking effect. This design cleverly uses mechanical advantages to convert manual pulling force into a stronger locking force. Subsequently, the rotation of the rotating shaft drives the ring 41 to squeeze inward, and further clamps the track crossbar 2 through the speed reduction block 43 on the inside of the ring 41. This clamping action directly causes the equipment to slow down because the friction between the speed reduction block 43 and the track crossbar 2 is significantly increased.Thereby effectively slowing down the descent speed of the equipment.
