[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a sports equipment with safety protection effect, which has the following beneficial effects:

[0019] 1. This safety-protecting sports equipment, through its automatic protection components, can perform emergency stoppage in the barbell's weightless state to prevent it from falling. Because weightlessness may mean that the exerciser's arms are in a state of weakness, the barbell will fall due to gravity. Therefore, the entire technical solution uses the power of gravity imbalance to determine and judge the stoppage of the barbell's fall, thereby protecting the exerciser lying on the equipment and avoiding accidents caused by the barbell falling on or pressing on their body, thus improving the overall safety of the exerciser.

[0020] 2. This sports equipment with safety protection features can improve the protection of the trigger mechanism through the set trigger protection component. Because when the operator's hands are holding the barbell, their feet are in a free state, so the exerciser can trigger the two receiving frames to rise according to the automatic exercise situation and the hand's fatigue, thereby supporting the barbell. At this time, the exerciser can easily release the barbell, and the two receiving frames will receive and support the barbell. Therefore, the operator does not need to lift the barbell back to the original position. Attached Figure Description

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-8 A type of sports equipment with safety protection includes a frame 1; a barbell 2; the barbell 2 is mounted on the frame 1.

[0032] In this embodiment, the protective mechanism includes an automatic protective component 4 and a trigger protective component 5; the automatic protective component 4 is used to stop the barbell 2 from falling when it is in a weightless state; the automatic protective component 4 includes a balancing device and a stopping device.

[0033] Furthermore, please refer to Figure 2 The balancing device includes a ring 402, which is fitted onto the barbell 2. A pull rod 401 is connected to the ring 402, and a housing 403 is slidably connected to the pull rod 401. The housing 403 is rotatably connected to the frame 1 via a shaft, and a limit nut 404 is threaded onto the pull rod 401. Considering the imbalance between the two arms during weightlifting, a balancing device is installed to restrict the barbell 2's vertical and horizontal movements. When the exerciser lifts the barbell 2, the pull rod 401 slides on the housing 403. When the barbell 2 is lifted forward, the housing 403 will cause the pull rod 401 to rotate, and the housing 403 will rotate around the connection center of the frame 1. Due to the restriction of the same structure on both sides, the barbell 2 can only move vertically and horizontally.

[0034] Furthermore, please refer to Figure 3 The stopping device includes a large gear 405, whose teeth mesh with those on the pull rod 401. A small gear 406 meshes with the lower surface of the large gear 405, and a triggering device 407 is installed on the small gear 406. The large gear 405 is rotatably connected inside the housing 403. Considering that the distance the pull rod 401 is pulled during actual exercise is not very long, the meshing of the large gear 405 and the small gear 406 is designed so that for every one rotation of the large gear 405, the small gear 406 rotates more times. Using the small gear 406 as the triggering medium makes the overall triggering more sensitive.

[0035] Furthermore, please refer to Figures 4-6 The triggering device 407 includes a fixing ring 4071, which is fixed inside the housing 403. A cylinder 4073 is positioned at the center of the fixing ring 4071. One side of the cylinder 4073 is fixed to one side of a pinion 406. A ratchet 4076 is rotatably connected to the cylinder 4073. A support rod 4074 is slidably connected to the cylinder 4073. One end of the support rod 4074 is fitted with a first spring 4075, and the other end of the first spring 4075 is connected to the cylinder 4073. When the pinion 406 rotates, it will drive the cylinder 4073 to rotate. The rotation of column 4073 will cause multiple ratchet 4076 connected to it to open. Due to the centrifugal force, the support rod 4074 rotates, compressing the first spring 4075, which in turn pushes the ratchet 4076 to open. So when the column 4073 rotates, the ratchet 4076 will be stuck in the slot 4072 on the fixing ring 4071. Therefore, the column 4073 will not rotate, the pinion 406 will not rotate, and the gear 405 will not rotate. At this time, the pull rod 401 will not move down. After being stuck, the entire pull rod 401 will lift the barbell 2 through the ring 402, so that the barbell 2 will no longer fall.

[0036] In addition, see Figure 5 The ratchet 4076 is provided with a sliding groove 4078, and a guide rod 4077 is slidably connected within the sliding groove 4078. The guide rod 4077 is connected to the support rod 4074. Considering that the centrifugal force generated by the overall rotation is in a swinging state, the guide rod 4077 has a certain sliding space within the sliding groove 4078 to facilitate smoother overall triggering. The inner wall of the fixing ring 4071 has a slot 4072 that engages with the ratchet 4076. Multiple ratchet 4076s and slots 4072 are provided, and the multiple ratchet 4076s are distributed in a circular array around the center of the cylinder 4073. The multiple ratchet 4076s and slots 4072 are provided to facilitate timely triggering during rotational centrifugal triggering, and the multiple slots 4072 make the overall triggering more sensitive.

[0037] In addition, please see Figure 7 The trigger protection component 5 uses the sliding of the exerciser's feet to limit the fall of the barbell 2. The trigger protection component 5 includes a bracket 3 connected to the frame 1. The bracket 3 has a push groove 502, and a pressure plate 501 is slidably connected to the push groove 502. One end of the pressure plate 501 is connected to a steel cable 505, and one end of the steel cable 505 is wound with a reel 504. The center of the reel 504 is connected to a rotating shaft 503, which is connected to the bottom of the bracket 3. An expansion block 506 is connected to the rotating shaft 503. When the exerciser... When the exerciser can no longer sustain the lift, their feet can trigger the pressure plate 501 to slide downwards. This sliding motion, via the steel cable 505, drives the pulley 504 to rotate. The rotation of the pulley 504 then drives the rotating shaft 503, which in turn drives the expansion block 506 to rotate. The rotation of the expansion block 506 serves as the trigger condition. Considering that the exerciser cannot control the barbell 2 with their hands, this component requires the exerciser to operate it with their feet, using the power of their feet to drive the lifting device 507 to open. The lifting device 507 is located at one end of the rotating shaft 503.

[0038] It is worth noting that, please refer to Figure 8 The lifting device 507 includes a support box 5071. A second spring 5073 is installed inside the support box 5071. A locking post 5072 is connected to the top of the second spring 5073. A receiving frame 5078 is connected to the top of the locking post 5072. Locking plates 5074 are engaged on both sides of the locking post 5072. A connecting rod 5075 is connected to one side of the locking plate 5074. The connecting rod 5075 is slidably connected to the support box 5071. A third spring 5076 is sleeved on the connecting rod 5075. When the expansion block 506 rotates, it will come into contact with the two contact plates 5077 and be pressed at an angle, causing the two contact plates 5077 to slide inside and outside the groove of the support box 5071. This will cause the two connected clamping plates 5074 to slide. At this time, the clamping plates 5074 will disengage from the clamping post 5072. After disengagement, the second spring 5073 at the bottom of the clamping post 5072 will push it upward, thereby causing the receiving frame 5078 to rise to a certain height. The exerciser can then release the barbell 2 directly. The barbell 2 will be supported by the receiving frames 5078 on both sides to deal with sudden emergency release of force.

[0039] It is worth noting that, please refer to Figure 8Two clamping plates 5074 are provided, which makes the whole structure more stable when supporting the barbell 2. Each clamping plate 5074 has a contact plate 5077 connected to its side. The contact plate 5077 is slidably connected to a groove in the support box 5071. An expansion block 506 is located between the two contact plates 5077, and the surface of the expansion block 506 is inclined. The inclined structure allows it to contact, squeeze, and slide with the two contact plates 5077 when it rotates, thereby causing the two clamping plates 5074 to slide relative to each other, thus releasing the restriction of the clamping post 5072 and allowing it to pop out.

[0040] Working principle: First, when the exerciser lies on the soft mat on the support 3, they can remove the barbell 2 hanging on the frame 1 for exercise. Considering the imbalance between the two arms during weightlifting, a balancing device is installed to limit the up-and-down and forward-and-backward movements of the barbell 2. When the exerciser picks up the barbell 2, the lever 401 slides on the housing 403. When the barbell 2 is lifted forward, the housing 403 will cause the lever 401 to rotate. The housing 403 will rotate around the connecting center of the frame 1. Due to the restriction of the same structure on both sides, the barbell 2 can only move forward-and-backward and up-and-down. If it tilts left or right, the lever 401 will prevent it from tilting. When the exerciser experiences a loss of strength in their hands or the barbell 2 experiences a weightless drop, the lever 401 will slide on the housing 403, causing the large gear 405 to rotate. The rotation of the large gear 405 will then drive the small gear 406 to rotate, which in turn will drive the cylinder 4073 to rotate. The rotation of the cylinder 4073 will cause the multiple ratchet plates 4076 connected to it to open, and due to centrifugal force, the support rod 4... Rotation 074 compresses the first spring 4075, which in turn pushes the ratchet 4076 to open. So when the cylinder 4073 rotates, the ratchet 4076 will be stuck in the slot 4072 on the fixed ring 4071. Therefore, the cylinder 4073 will not rotate, the small gear 406 will not rotate, and the large gear 405 will not rotate. At this time, the pull rod 401 will not move down. After being stuck, the entire pull rod 401 will lift the barbell 2 through the ring 402, so that the barbell 2 will no longer fall. Under normal circumstances, although the lever 401 slides up and down, the rotation of the large gear 405 and the small gear 406 is relatively stable. However, in a state of weightlessness and loss of force, the lever 401 slides more rapidly. Therefore, the large gear 405 drives the small gear 406 to rotate faster, causing the multiple ratchet plates 4076 on the cylinder 4073 to open due to the greater centrifugal force, thus locking. Therefore, exercisers should not lift the barbell 2 too quickly; they must do so at a certain pace. This also serves to protect the exerciser and prevent muscle injury caused by excessive speed. The overall principle can be understood as the structure of a car seatbelt. When the seatbelt is normally stretched, it will not lock. Locking only occurs when there is rapid sliding, thus preventing injury from the barbell 2 falling due to loss of force or exercise errors.Furthermore, this technical solution also includes a trigger protection component 5. This component is triggered manually. Considering that the exerciser cannot operate the barbell 2 with their hands, this component requires the exerciser to operate it with their feet. When the exerciser can no longer hold the lift, their feet can trigger the pressure plate 501 to slide downwards. After sliding, the steel cable 505 will drive the pulley 504 to rotate. The rotation of the pulley 504 will drive the rotating shaft 503 to rotate, which in turn will drive the expansion block 506 to rotate. The rotation of the expansion block 506 will contact the two contact plates 5077 and perform inclined compression, causing... Two contact plates 5077 slide inside and outside the grooves of the support box 5071, thereby driving two connected locking plates 5074 to slide. At this time, the locking plates 5074 will disengage from the locking post 5072. After disengagement, the second spring 5073 at the bottom of the locking post 5072 will push it upward, thereby driving the receiving frame 5078 to rise to a certain height. Then, the locking plates 5074, under the action of the springs on both sides, will push the two locking plates 5074 to engage with the locking post 5072 vertically. When the locking post 5072 slides downward, it is in a reverse gear state with the locking plates 5074; when it slides upward, it is in a forward gear state. The forward gear state makes it easier for the locking post 5072 to pop out as a whole. At this time, the operator can directly release the barbell 2. The barbell 2 will be supported by the receiving frames 5078 on both sides, so the exerciser can rest and recover their strength. This also provides protection for the exerciser in case of sudden emergency dissipation.
