Description

Technical Field

[0001] The invention relates to the technical field of physical training devices, and in particular to a physical training device with a protective structure. Background Art

[0002] Physical fitness is the basic athletic ability of the human body, which is manifested through athletic qualities such as strength, speed, endurance, coordination, flexibility, and agility. It is an important component of an athlete's competitive ability. The level of physical fitness is closely related to the morphological and functional characteristics of the human body. Based on the performance and role of physical fitness in different populations, physical fitness can be divided into two levels: healthy physical fitness and competitive physical fitness. Healthy physical fitness refers to the functional ability of organ systems that are necessary for any population and is the basis of competitive physical fitness. Competitive physical fitness is further developed on the basis of healthy physical fitness and is the physical functional ability required for competitive competitions.

[0003] With the continuous improvement of living standards, people pay more and more attention to their physical health, and exercise is one of the effective means to improve health and physical fitness. The barbell bench press is one of the common machine exercises in the gym. It has a significant effect on exercising chest muscles, which not only helps to improve health and physical fitness, but is also an important training method for developing competitive physical fitness. However, this sport is very intense. If it is not operated properly, such as the barbell falling, it may cause injuries to the user. Therefore, when using the bench press, the coach needs to hold it with both hands to ensure safety. In order to effectively protect one person when using it and avoid potential safety risks, the unloading protection bench press was invented. The addition of this device allows individuals to ensure safety through mechanical structures even without the on-site protection of coaches during exercise, thereby greatly improving the safety of the barbell bench press, which is of great significance for promoting healthy physical training and increasing the enthusiasm of the public to participate in fitness.

[0004] However, the general protection device has poor stability, either high sensitivity, which will affect the user's normal exercise rhythm when in use, or poor sensitivity, which cannot provide protection in time, and the existing protection devices mostly use spring structures, which have a low service life and will cause safety hazards if not replaced for a long time. Secondly, the existing method of relying on spring structures to buffer the fall of barbells, such as the Chinese patent with authorization announcement number CN111840893B, which discloses a weight-unloading protection bench press frame, has a spring structure exposed to the outside, which is very susceptible to external impact damage, and when the spring is stretched, if the spring breaks, it may cause harm to people around the equipment.

[0029] Embodiment 1: Figures 1 to 5As shown, the present application is a physical training device with a protective structure, comprising a vertical support 100, a reclining seat 500, a barbell 200 and a protective device, wherein there are two vertical supports 100, and the two vertical supports 100 are respectively vertically arranged on both sides of one end of the reclining seat 500 in the length direction, and a horizontally arranged crossbeam is fixed between the two vertical supports 100, and the crossbeam is perpendicular to the length direction of the reclining seat 500, the bottom end of the vertical support 100 is fixed to the ground, and a placement seat 110 is fixedly installed on the top of the vertical support 100, and the two placement seats 110 are used to place the barbell 200; a slide rail 120 is provided on the front side wall of the vertical support 100, and the vertical support 100 is away from the rear side wall of the reclining seat 500. A leg is fixed at the bottom, and the slide rail 120 is vertically arranged along the length direction of the vertical bracket 100. Safety bars 300 are slidably connected to the two slide rails 120. The safety bar 300 is a horizontally arranged rectangular block. The length direction of the safety bar 300 is parallel to the length direction of the reclining seat 500. A saddle 310 is provided on the top surface of the safety bar 300. The saddle 310 is a concave arc surface for supporting the barbell 200; a pressure column 320 is fixed to the end of the lower end surface of the safety bar 300 away from the slide rail 120. The pressure column 320 is vertically arranged, and a safety cylinder 400 is coaxially arranged below the pressure column 320. A base 410 is fixed to the bottom of the safety cylinder 400. The base 410 is fixed to the ground; the safety cylinder 400 and the pressure column 320 are both cylindrical, a safety cavity 440 is provided inside the safety cylinder 400, a circular air vent 430 is coaxially provided on the top of the safety cavity 440, the diameter of the air vent 430 is larger than the diameter of the pressure column 320, the bottom end of the pressure column 320 coaxially passes through the air vent 430 and is located inside the safety cavity 440; a pressure plate 330 is coaxially fixedly connected to the bottom end of the pressure column 320, the pressure plate 330 is slidably connected to the inner side wall of the safety cavity 440, and the edge of the pressure plate 330 is dynamically sealed with the side wall of the safety cavity 440; a plurality of air vents 331 and a connecting seat 330 are provided on the pressure plate 330 32; the vent holes 331 are through holes, and a plurality of vent holes 331 are evenly distributed in a ring shape along the axis of the pressure plate 330; the connecting seat 332 is elastically connected to the top of the safety cavity 440 by an elastic pull rope 333, and the bottom of the pressure plate 330 is covered and fixed with an elastic arc plate 335, and the elastic arc plate 335 is made of elastic rubber, and the elastic arc plate 335 is a hemispherical arc surface protruding downward as a whole; a vent bottom opening 336 is opened at the bottom center of the elastic arc plate 335, and the vent bottom opening 336 is a through hole; a sealing gasket 334 is fixed at the bottom center of the pressure plate 330, and the sealing gasket 334 is made of elastic rubber, and the area of ​​the sealing gasket 334 is larger than the area of ​​the vent bottom opening 336.

[0030] When the safety bar 300 is not subjected to external force, the pressure plate 330 slides upward to the top of the safety cavity 440 driven by the elastic pull rope 333. During the upward sliding process, the elastic arc plate 335 is always in a downward convex state, and the external air enters the vent 430, the vent hole 331 and the vent bottom 336 in sequence, so that the gas enters the safety cavity 440 to stabilize the air pressure, so that the pressure plate 330 slides normally; when the user is training normally, the safety bar 300 is pressed down by the barbell 200, and the pressure column 320 presses the pressure plate 330 at a uniform speed along with the safety bar 300, and the gas inside the safety cavity 440 is discharged from the vent bottom 336, the vent hole 331 and the vent 430 in sequence, so that The user can perform the bench press exercise normally; when the barbell 200 falls off accidentally, the barbell 200 rod hits the saddle 310, so that the barbell 200 hits the safety bar 300, and the safety bar 300 drives the pressure column 320, and the pressure column 320 pushes the pressure plate 330 to move downward rapidly. During the downward movement of the pressure plate 330, the air inside the safety chamber 440 is quickly compressed, and the elastic arc plate 335 is squeezed by the air and deformed upward, so that the ventilation bottom port 336 is tightly attached to the sealing gasket 334, so that the ventilation bottom port 336 is closed, and a closed space is formed inside the safety chamber 440. The air pressure inside the safety chamber 440 provides a reaction force to quickly support the barbell 200, so that the barbell 200 cannot continue to fall.

[0031] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0032] In this embodiment, the safety bar 300 and the safety cylinder 400 are arranged to cooperate with each other, and the huge impact force when the barbell 200 falls is used to seal the inside of the safety cylinder 400. The gas enclosed in the safety cylinder 400 automatically locks the position of the safety bar 300 and provides a strong buffer. The reaction force of the air pressure inside the safety cylinder 400 supports the barbell 200, so that the barbell 200 cannot continue to slide down; when the barbell 200 is lifted, the safety bar 300 is automatically unlocked, which solves the technical problems of the poor stability of the protective device in the prior art and the potential safety hazards when used, and realizes the technical effect of using the strong air pressure generated by the falling weight of the barbell 200 to buffer the barbell 200, thereby improving the safety.

[0033] Embodiment 2: Considering that in the above embodiment 1, the user may encounter a situation of exhaustion during training, and has placed the barbell 200 in front of the chest but is unable to lift it again. At this time, the pressure of the barbell 200 may easily cause the user to have difficulty breathing and suffocate, and at this time, the pressure plate 330 has no space to move downward, making it difficult to rescue the user. Therefore, it is necessary to improve the device, such as Figure 6 As shown, the specific structure is as follows:

[0034] The controller 450 and the air pressure pump 470 are fixedly embedded in the bottom of the safety cylinder 400, respectively. The input end of the air pressure pump 470 passes through the side wall of the safety cylinder 400 and is connected to the external air. The output end of the air pressure pump 470 penetrates upward to the bottom of the safety cavity 440. A pressure sensor 460 is fixedly installed at the bottom center of the safety cavity 440. Both the pressure sensor 460 and the air pressure pump 470 are connected to the controller 450 by electrical signals.

[0035] A vent cylinder 360 is coaxially fixedly connected to the vent bottom opening 336, and a sliding disk 350 is coaxially fixed to the bottom of the vent cylinder 360. The sliding disk 350 is slidably connected to the inner wall of the safety cavity 440, and the edge of the sliding disk 350 is dynamically sealed with the inner wall of the safety cavity 440. A vent channel 361 is coaxially opened inside the vent cylinder 360, and the vent channel 361 is a through hole; when the bottom end surface of the sliding disk 350 contacts the pressure sensor 460, the sliding disk 350 can transmit the pressure from the safety bar 300; when the safety bar 300 moves upward, the gravity of the sliding disk 350 can pull down the elastic arc plate 335, so that the elastic arc plate 335 quickly returns to the convex state, so that the vent channel 361 is conductive; when the barbell 200 impacts the safety bar 300, the top of the vent cylinder 360 can quickly press the sealing pad 334, so that the vent channel 361 is more stably closed, so that the overall response of the device is faster, but it does not affect the training rhythm of the user.

[0036] The controller 450 is preferably a single chip microcomputer, which is a prior art and will not be described in detail.

[0037] When the pressure value detected by the pressure sensor 460 is greater than the set value, the pressure sensor 460 transmits a signal to the controller 450, and the controller 450 controls the air pressure pump 470 to pump gas into the safety chamber 440. At this time, the top of the ventilator 360 is pressed against the sealing gasket 334, and the ventilation channel 361 is in a closed state, so that the gas pumped into the safety chamber 440 lifts the barbell 200.

[0038] The technical solutions in the above embodiments of the present application have at least the following technical effects or advantages:

[0039] In this embodiment, a sliding plate 350 and a vent cylinder 360 are provided, and the vent cylinder 360 is used to press against the sealing gasket 334 in case of an emergency, thereby closing the safety cavity 440. When the barbell 200 is pressed on the user, air is quickly pumped into the safety cavity 440 to lift the barbell 200, thereby further avoiding accidents.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
