Technical Field

[0001] The present application belongs to the field of fitness equipment, and specifically relates to a push-up machine protection device. Background Art

[0002] The push-up is a staple chest exercise in the gym. The standard move involves lying flat on your back, placing a barbell above your chest, and gripping the lever to push upward. Keeping your arms steady and using your chest to generate force, the push-up is crucial. To build muscle, heavy weights are typically used, and the results are only noticeable when you reach exhaustion.

This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect.

[0033] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present application and simplify the description. They do not indicate or imply that the devices or elements referred to must have a specific direction, be constructed and operate in a specific direction. Therefore, they should not be understood as limiting the present application.

[0034] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0035] The accompanying drawings are the best embodiments of the pusher protection device. The present application will be further described in detail below in conjunction with the accompanying drawings.

[0036] Depend on Figures 1 to 9 As shown, a pusher protection device includes a vertical plate 1 and a locking mechanism. A plurality of vertically spaced hanging grooves 102 are recessed in the middle of the front end surface of the vertical plate 1. Side through grooves 103 are connected on both sides of the hanging grooves 102. A driving surface 101 is provided on the side of the side through groove 103 facing away from the hanging groove 102.

[0037] The locking mechanism comprises a circular sleeve 2 and a sleeve 3 fixedly connected to each other, wherein the through hole 301 on the sleeve 3 for passing the lever 4 is arranged horizontally. The circular sleeve 2 is sleeved on the vertical plate 1 and slides up and down on the vertical plate 1.

[0038] A centrifugal force control component is provided inside the circular sleeve 2, which includes a coaxially connected passive wheel 5 and a rotating drum 7. The rotating drum 7 is slidably connected to a U-shaped rod 8. The driving surface 101 drives the passive wheel 5 to rotate. After the speed of the rotating drum 7 reaches a threshold, the U-shaped rod 8 is mounted on the hanging inclined groove 102.

[0039] During use, the barbell lever 4 is passed through the through hole 301, and the bottom of the vertical plate 1 is fixedly connected to the ground via a support seat, or the top of the vertical plate 1 is fixedly connected to the top frame of the gantry. After the exerciser lies down, he pushes the barbell upward. If an accident occurs during the descent and the barbell falls, the rotation speed of the passive wheel 5 increases, thereby driving the rotating drum 7 to rotate rapidly. The centrifugal force on the U-shaped rod 8 increases, causing it to be thrown outward and then fit onto the inclined surface outside the hanging inclined groove 102, preventing the locking mechanism from descending. The barbell is then fixed and stopped from falling, preventing it from hitting the exerciser, thus providing protection.

[0040] In order to provide better support for the barbell, this embodiment includes two vertical plates 1 arranged at intervals, and each vertical plate 1 is provided with a locking mechanism.

[0041] The arrangement of the two vertical plates and the locking mechanism not only provides better support for the barbell, but also limits the movement path of the barbell, keeping it always in a horizontal state, thereby optimizing the exercise effect.

[0042] In order to achieve the effect of hooking and locking, the opening of the hooking chute 102 is arranged upward, and the U-shaped rod 8 needs to be rotated from top to bottom and hooked on the outer inclined surface of the hooking chute 102. In this connection method, when the lock needs to be released, just push the barbell upward, and the U-shaped rod 8 can move up along the outer inclined surface of the hooking chute 102 and disengage from the hooking chute 102.

[0043] To achieve the above purpose, it is necessary to adjust the rotation direction of the drum 7 when the barbell moves downward, and then a drive wheel 10 is provided for rotation inside the circular sleeve 2. The drive wheel 10 is connected to the driving surface 101. The drive wheel 10 is coaxially connected to the driving wheel 11, and the driving wheel 11 drives the driven wheel 5 to rotate. The driving wheel 11 and the driven wheel 5 are both gears, and the two are meshed and connected. The setting of the driving wheel 11 reverses the direction of the driven wheel 5 to ensure that the rotation direction of the drum 7 is correct.

[0044] There are two ways to connect the driving wheel 10 and the driving surface 101 , and both of the following connection methods can be used.

[0045] In the first type, the driving wheel 10 is a gear, and the driving surface 101 is a rack, and the two are meshed and connected.

[0046] The second type is that the driving wheel 10 is a rubber wheel and the driving surface 101 is a rubber surface, and the two are connected by friction.

[0047] In order to ensure that the U-shaped rod 8 is isolated from the vertical plate 1 during the normal descent of the barbell, it will not be set inside the hanging inclined groove 102.

[0048] The circumferential surface of the rotating drum 7 is concave with two chute grooves 701, and the end rods on both sides of the U-shaped rod 8 are slidably arranged inside the chute grooves 701. The ends of the end rods on both sides of the U-shaped rod 8 are provided with spring seats, and the end rods on both sides of the U-shaped rod 8 located inside the chute grooves 701 are provided with springs 9.

[0049] Under the push of the spring 9 , the U-shaped plate 8 moves toward the axis of the drum 7 . Only when the rotation speed of the drum 7 reaches a threshold and the centrifugal force is large enough, the middle rod of the U-shaped plate 8 will be thrown into the interior of the hanging chute 102 .

[0050] The side of the driven wheel 5 facing away from the drum 7 is coaxially connected to the first rotating shaft 6, which is inserted into the inner wall of the circular sleeve 2. The side of the driving wheel 10 facing away from the driving wheel 11 is coaxially provided with a second rotating shaft 12, which is inserted into the inner wall of the circular sleeve 2.

[0051] In order to increase the driving force for downward movement, the circular sleeve 2 is internally provided with two driving wheels 10 and two active wheels 11, which are coaxially fixedly connected by a connecting shaft 13. The two driving wheels 10 are respectively connected to the driving surfaces 101 on both sides of the front end surface of the vertical plate 1.

[0052] The above describes the implementation methods of the present application in detail in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present application.
