Description

Technical Field

[0001] The present invention relates to the technical field of physical fitness training, and particularly to a sports physical fitness training device with a counting structure. Background Art

[0002] Bench press is a compound upper limb strength training exercise, mainly used to enhance the strength of the chest muscles, anterior deltoids and triceps brachii; the athlete lies flat on a bench press bench, holds a barbell or dumbbells with both hands, pushes the weight from the chest position until the arms are straight (the elbows are slightly bent), and then slowly lowers it back near the chest; the core goal of this exercise is to stimulate the overall development of the pectoralis major muscle, while enhancing upper limb explosive power and stability. Athletes (such as powerlifters or ball players involving upper limb exertion) generally perform bench presses during daily training because it can directly improve the thrust and explosive power required for sports.

[0003] When athletes perform bench press training, they usually need to do it in multiple sets, and the number of each set is fixed. This requires accurate counting during the bench press. Existing bench press devices are not convenient for accurate counting. During the training process, due to the different intensities and postures of each bench press, it is easy to cause insufficient intensity of the bench press, which will affect the training volume of the bench press training, resulting in the inability to reach the daily training intensity. At the same time, athletes cannot accurately feel the training volume and insufficient intensity. Over time, it will cause the physical fitness training to fail to meet the standards.

[0004] Combining the above problems, we will find that when the existing sports physical fitness training devices on the market are in use, it is very difficult to avoid the above-mentioned problems at the same time. And even if they can be solved, they need to be solved with the cooperation of external tools, thus unable to achieve the desired effect. Therefore, we propose a sports physical fitness training device with a counting structure. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. Through the cooperation of the precise counting mechanism and the position adjustment mechanism, the present invention can convert the up-and-down movement of the barbell rod during the athlete's bench press into the rotation of the second spur gear. Thus, when the athlete is undergoing physical training, the number of bench presses performed by the athlete can be accurately counted. Subsequently, only by counting the number of rotation circles of the sliding plate, the precise counting of bench presses can be achieved. Moreover, the number of deflection circles and the angle of the sliding plate can intuitively display the number of bench presses, enabling the athlete to more intuitively view the training volume. Thereby, the athlete can adjust the number of bench presses according to the currently achieved training volume, and further enable the physical training to meet the daily standard.

[0017] 2. Through the pulling component, when the rack moves due to extrusion, in order to ensure that the rack can still mesh with the first spur gear when the athlete lifts the barbell rod upward next time, after the barbell rod descends to a certain height, the pulling component is squeezed at this time, driving the pulling component to operate, and then the rack can be displaced, enabling the subsequent rack to mesh with the first spur gear. Through the pulling component, during the bench press, the quantity display component can accurately count, and will not be affected by large-scale limb movements during the bench press, resulting in inaccurate counting of the quantity display component. Through the pulling component, during the athlete's daily training, accurate counting and reading can be achieved, enabling the athlete to adjust the total number of bench presses according to the number of bench presses achieved today, and further enabling the athlete's single-day physical training to meet the standard.

[0018] 3. When in use, through the combined use of the quantity display component and the precise counting mechanism, when the second spur gear rotates, the longitudinal rotation amount of the second spur gear can be converted into the lateral movement amount of the scale rod. Thus, the number of bench presses can be intuitively obtained through the moving distance of the scale rod. By the difference between the existing number of bench presses and the single-day bench press target number, it can intuitively reflect how many more bench presses the athlete needs to do to complete the daily target. Therefore, through the combined use of the quantity display component and the precise counting mechanism, it can assist the athlete to meet the daily physical training standard.

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1: Please refer to Figures 1 - 8, the present invention provides a technical solution: a physical fitness training device with a counting structure, including a bench press component 1, characterized in that: counting components 2 are provided at both ends of the bench press component 1, and a pulling component 3 and a quantity display component 4 are installed on the surfaces of the two counting components 2; The bench press component 1 includes support members 11 and adjustable placement frames 13. There are two support members 11, and the two support members 11 are fixedly connected to a lying member 12 together. There are two adjustable placement frames 13, and anti-slip members 14 are fixedly connected to the upper ends of the two adjustable placement frames 13. The two placement frames 13 are respectively arranged on both sides of the lying member 12. A barbell bar 15 is placed above the two anti-slip members 14, and barbell plates 16 are installed on the surface of the barbell bar 15; The counting component 2 includes a precise counting mechanism 21 and a position adjustment mechanism 22. The precise counting mechanism 21 is installed at the side end of the adjustable placement frame 13, and the position adjustment mechanism 22 is installed on the precise counting mechanism 21. The precise counting mechanism 21 and the position adjustment mechanism 22 are used in cooperation; The pulling component 3 is arranged on the surface of the precise counting mechanism 21, and the pulling component 3 and the position adjustment mechanism 22 are used in cooperation. The quantity display component 4 is arranged at the side end of the precise counting mechanism 21, and the quantity display component 4 and the precise counting mechanism 21 are used in cooperation.

[0023] The precise counting mechanism 21 includes a first spur gear 2101, a mounting frame 2102, a fixing plate 2103, a rectangular frame 2105, a rack 2108 and a second spur gear 2111. The mounting frame 2102 is fixedly connected to the side end of the adjustable placement frame 13. A first sliding groove 2107 and a second sliding groove 2110 are formed on the surface of the mounting frame 2102. The rectangular frame 2105 is slidably connected inside the second sliding groove 2110. The rack 2108 is slidably connected to the surface of the mounting frame 2102. The first spur gear 2101 is rotatably connected to the surface of the barbell bar 15. The fixing plate 2103 is fixedly connected to the surface of the barbell bar 15. The second spur gear 2111 is rotatably connected inside the rectangular frame 2105. The precise counting mechanism 21 further includes a connecting bolt 2104 and an internal thread member 2106. The internal thread member 2106 is fixedly connected to the surface of the rectangular frame 2105, and the internal thread member 2106 is slidably connected inside the first sliding groove 2107. The fixing plate 2103 is threadedly connected to the surface of the connecting bolt 2104. Therefore, the fixing plate 2103 and the internal thread member 2106 can be connected through the connecting bolt 2104, so that the first spur gear 2101 and the rectangular frame 2105 can move up and down synchronously, and then the second spur gear 2111 can be driven to move up and down synchronously.

[0024] The position adjusting mechanism 22 includes a pressing plate 2201, a moving plate 2202, a first lead screw 2203, a first bevel gear 2204, a deflecting member 2209, an expanding member 2210, a limiting plate 2211 and an adjustable telescopic rod 2212. An insertion groove 2109 is formed on the surface of the mounting bracket 2102. The pressing plate 2201 is slidably connected to the inside of the insertion groove 2109. The deflecting member 2209 is arranged above the pressing plate 2201. The lower end of the deflecting member 2209 is fixedly connected to the adjustable telescopic rod 2212. The lower end of the adjustable telescopic rod 2212 is fixedly connected to the expanding member 2210. The expanding member 2210 and the pressing plate 2201 are connected by a rotating shaft. The pressing plate 2201 and the expanding member 2210 are fixedly connected by the limiting plate 2211. The moving plate 2202 is fixedly connected to the surface of the deflecting member 2209. The moving plate 2202 is threadedly connected to the surface of the first lead screw 2203. The first bevel gear 2204 is fixedly sleeved on the surface of the first lead screw 2203. The position adjusting mechanism 22 further includes a second bevel gear 2205, a second lead screw 2206, a first spiral sleeve 2207 and a first sleeve plate 2208. The second lead screw 2206 is threadedly connected to the surface of the first sleeve plate 2208 through a bearing. The second lead screw 2206 and the first spiral sleeve 2207 are threadedly connected. The second bevel gear 2205 is fixedly connected to the end of the second lead screw 2206, and the second bevel gear 2205 meshes with the first bevel gear 2204. The first sleeve plate 2208 is connected to the mounting bracket 2102 by bolts. The moving plate 2202, the first lead screw 2203, the first bevel gear 2204, the second bevel gear 2205, the second lead screw 2206, the first spiral sleeve 2207 and the first sleeve plate 2208 are all provided with two, and are all symmetrically arranged. Since the rack 2108 will move during use, in order to enable the rack 2108 to mesh with the first spur gear 2101 when the first spur gear 2101 rises, and when the first spur gear 2101 descends, it can be squeezed by the first spur gear 2101 so as not to mesh with the first spur gear 2101. Therefore, the position adjusting mechanism 22 can be provided on the mounting bracket 2102. By the position adjusting mechanism 22, the position of the rack 2108 can be controlled, so that the rack 2108 can mesh with the first spur gear 2101 when the first spur gear 2101 rises, and will not hinder the descent of the first spur gear 2101 when the first spur gear 2101 descends.

[0025] The specific implementation of this embodiment is as follows: When an athlete performs bench press training, they can first lie on the lying component 12. Then, they can assemble the barbell plates 16 onto the barbell bar 15, and remove the barbell bar 15. Place the first spur gear 2101 inside the mounting frame 2102 and slowly move it to the bottom. Mesh the first spur gear 2101 with the rack 2108 and the second spur gear 2111. By aligning the fixed plate 2103 and the internal thread part 2106, connect the fixed plate 2103 and the internal thread part 2106 through the connecting bolt 2104. Since the internal thread part 2106 is slidably connected inside the first sliding groove 2107, and the internal thread part 2106 is connected to the rectangular frame 2105, while the rectangular frame 2105 is slidably connected inside the second sliding groove 2110. At this time, when the athlete lifts the barbell bar 15 upward, the first spur gear 2101 will move upward accordingly. And because the first spur gear 2101 meshes with the rack 2108, at this time the first spur gear 2101 will rotate, and then can drive the second spur gear 2111 to rotate. And when the barbell bar 15 is lifted upward, at this time the fixed plate 2103, the connecting bolt 2104, and the rectangular frame 2105 will move upward together. Therefore, at this time the second spur gear 2111 can be in mesh with the first spur gear 2101 throughout the process. When the athlete lifts the barbell bar 15, since the number of teeth of both the rack 2108 and the second spur gear 2111 is twice that of the first spur gear 2101, when the first spur gear 2101 moves to the highest position, at this time the first spur gear 2101 will rotate two circles and drive the second spur gear 2111 to rotate one circle. At this time, it is counted as one. Since the second spur gear 2111 cannot rotate in the reverse direction under the action of the quantity display component 4, when the second spur gear 2111 starts to count, the first spur gear 2101 meshing with the second spur gear 2111 also cannot rotate in the reverse direction. In order to enable the first spur gear 2101 to move downward, the rack 2108 needs to be slidably arranged on the surface of the mounting frame 2102. When the first spur gear 2101 moves downward, it will squeeze the rack 2108, thereby pushing the rack 2108 to move. At this time, the rack 2108 is not meshed with the first spur gear 2101, and thus cannot drive the first spur gear 2101 to rotate in the reverse direction. Before the first spur gear 2101 rises, in order to enable the rack 2108 to mesh with the first spur gear 2101 again, at this time, the rack 2108 can be driven to move forward through the pulling component 3, so as to mesh with the first spur gear 2101 again. And through the position adjusting mechanism 22, the position of the rack 2108 is fixed, so that the rack 2108 can be stably meshed with the first spur gear 2101, and then the above counting operation can be repeated. When the barbell bar 15 moves to the highest position, in order to enable the first spur gear 2101 to squeeze the rack 2108, thereby changing its position and then not meshing with the first spur gear 2101,At this time, the position limit of the position adjustment mechanism 22 on the rack 2108 can be released, so that the first spur gear 2101 can move downward. In specific use, when the barbell bar 15 is first placed in the mounting frame 2102, the downward movement of the barbell bar 15 will gradually squeeze the first spiral sleeve 2207. Since the first spiral sleeve 2207 is slidably arranged on the first set plate 2208 and is threadedly connected to the second screw rod 2206, when the first spiral sleeve 2207 is squeezed downward, it will drive the second screw rod 2206 to rotate, and then the second bevel gear 2205 can be driven to rotate, thereby driving the first bevel gear 2204 and the first screw rod 2203 to rotate. Through the rotation of the first screw rod 2203, the first screw rod 2203 can be connected to the first screw rod 2 203 threadedly connected to the movable plate 2202 moves, which can drive the pressure plate 2201 to move, so that the pressure plate 2201 can move inside the insertion groove 2109. At this time, the pressure plate 2201 will press against the rack 2108, so that the rack 2108 cannot move inward, so that the rack 2108 can stably mesh with the first spur gear 2101. At this time, the barbell bar 15 can be lifted upward, and counting is performed during the lifting period. Since the movable plate 2202, the first screw rod 2203, the first bevel gear 2204, the second bevel gear 2205, the second screw rod 2206, the first spiral sleeve 2207 and the first set plate 2208 are all provided with two, and are symmetrically arranged, when the barbell bar 15 continues to move upward, the first screw rod 2203, the first bevel gear 2204, the second bevel gear 2205, the second screw rod 2206, the first spiral sleeve 2207 and the first set plate 2208 are all provided with two, and are symmetrically arranged. When moving upward, the barbell bar 15 will squeeze another first spiral sleeve 2207 upward, and repeat the above steps. At this time, the pressure plate 2201 will slowly move to the outside of the insertion slot 2109. After the pressure plate 2201 is completely moved out, the first spur gear 2101 can squeeze the rack 2108 inward, thereby moving downward. During training, repeating the above operations can complete accurate counting. In specific use, in order to facilitate the placement of the barbell bar 15 into the mounting frame 2102, a deflection member 2209 can be set between the pressure plate 2201 and the moving plate 2202, and an adjustable telescopic rod 2212 is set at the lower end of the deflection member 2209, and an expansion member 221 is set at the lower end of the adjustable telescopic rod 2212. 0, the expansion piece 2210 and the pressure plate 2201 are connected through a rotating shaft, and then the position between the expansion piece 2210 and the pressure plate 2201 can be fixed by a limit plate 2211, so as to facilitate the subsequent counting operation. When the athlete's arm cannot completely squeeze the barbell bar 15 into the first spiral sleeve 2207, the adjustable telescopic rod 2212 can be controlled to retract, so that the position of the first screw rod 2203 is moved downward, which is convenient for the subsequent squeezing of the first spiral sleeve 2207. After the barbell bar 15 is placed in the mounting frame 2102, the deflection piece 2209 can be rotated at this time, so as to drive the moving plate 2202 to move, and then the first set of plates 2208 can be detachably connected to the mounting frame 2102 by bolts.Thus, during the bench press, the first set of plates 2208 can be stably set. Further, the barbell 15 can squeeze the first spiral sleeve 2207, enabling the rack 2108 to move when the barbell 15 descends subsequently, thereby preventing the barbell 15 from being restricted. Through the combined use of the precise counting mechanism 21 and the position adjustment mechanism 22, when an athlete conducts physical training, relatively precise counting can be performed. The recorded quantity is subtracted from the quantity that needs to be done daily, so as to calculate how many more need to be done, ensuring the training effect.

[0026] Embodiment 2: Please refer to Figures 1 - 8 The present invention provides a technical solution: The pulling assembly 3 includes a third bevel gear 304, a fourth bevel gear 305, and a fourth lead screw 306. The surface of the fourth lead screw 306 is threadedly connected to the inner wall of the rack 2108, and the fourth lead screw 306 is rotatably connected to the surface of the mounting bracket 2102. The fourth bevel gear 305 is fixedly connected to the end of the fourth lead screw 306. The third bevel gear 304 is rotatably connected to the surface of the mounting bracket 2102, and the third bevel gear 304 and the fourth bevel gear 305 are meshed; The pulling assembly 3 further includes a second set of plates 301, a second spiral sleeve 302, and a third lead screw 303. The second set of plates 301 is fixedly connected to the surface of the mounting bracket 2102. The second set of plates 301 is sleeved on the surface of the second spiral sleeve 302. The surface of the third lead screw 303 is threadedly connected to the inner wall of the second spiral sleeve 302. The third bevel gear 304 is fixedly connected to the end of the third lead screw 303.

[0027] The specific implementation of this embodiment is as follows: During use, in order to enable the pressure plate 2201 to be located behind the rack 2108 when the barbell 15 ascends and thus hold it in place, a third bevel gear 304 can be provided on the mounting bracket 2102, and the third bevel gear 304 is connected to the third lead screw 303. The second set of plates 301 is arranged on the mounting bracket 2102. The second spiral sleeve 302 is slidably connected to the second set of plates 301 and threadedly connected to the third lead screw 303. When the barbell 15 descends, the barbell 15 first squeezes the second spiral sleeve 302, thereby driving the third bevel gear 304 to rotate, and further driving the fourth bevel gear 305 and the fourth lead screw 306 to rotate. Since the rack 2108 is threadedly connected to the fourth lead screw 306, the rack 2108 will move outward at this time. Then the barbell 15 continues to move downward, further squeezing the first spiral sleeve 2207, thereby completing the limitation of the rack 2108. Through the pulling assembly, the quantity display assembly can accurately count. During the daily training of the athlete, the pulling assembly enables accurate counting, so that the athlete can know the number of bench presses reached today.

The sliding plate 407 is sleeved on the surface of the third spiral sleeve 401, and the third spiral sleeve 401 is fixedly connected to the second spur gear 2111. The telescopic rod 405 is fixedly connected to the surface of the sliding plate 407. The surface of the fifth lead screw 403 is threadedly connected to the inner wall of the third spiral sleeve 401. The push plate 409 is fixedly connected to the telescopic end of the telescopic rod 405. A receiving hole 410 is formed on the surface of the third spiral sleeve 401. The scale rod 406 is fixedly connected to the surface of the push plate 409, and the scale rod 406 is slidably connected to the inside of the receiving hole 410; The quantity display component 4 further includes a clamping member 404. The clamping member 404 is fixedly connected to the end of the fifth lead screw 403. The clamping member 404 and the push plate 409 are detachably connected by bolts.

[0029] The specific implementation of this embodiment is as follows: When counting, if only the number of rotations of the second spur gear 2111 is observed for counting, it may lead to inaccurate counting or difficult counting. At this time, a sliding plate 407 can be slidably arranged in the limiting groove 2112, and the third spiral sleeve 401 is connected to the second spur gear 2111, and the third spiral sleeve 401 rotates through the sliding plate 407. The telescopic rod 405 is arranged on the sliding plate 407, and the telescopic end of the telescopic rod 405 is connected to the push plate 409. Then, the fifth lead screw 403 is threadedly connected to the sliding plate 407. Since the clamping member 404 is connected to the fifth lead screw 403 and the clamping member 404 is connected to the push plate 409 by bolts, the scale rod 406 is connected to the push plate 409. When the second spur gear 2111 rotates, it will drive the third spiral sleeve 401 to rotate, which can further drive the fifth lead screw 403 to push the push plate 409 to move, and then drive the scale rod 406 to stretch. At this time, by observing the scale on the scale rod 406, the number of bench presses can be known. When in use, in order to prevent the third spiral sleeve 401 from rotating in the reverse direction and driving the push plate 409 to move in the reverse direction, a ratchet 402 can be arranged on the third spiral sleeve 401, and the ratchet 402 is engaged with the ratchet teeth 408. At this time, the third spiral sleeve 401 cannot rotate in the reverse direction. And in specific use, since athletes with different arm lengths usually have different bench press heights, the rotation angle of the second spur gear 2111 may be different during a single bench press. At this time, a bench press test can be carried out first. When the athlete pushes the barbell rod 15 to the highest position, the number displayed on the scale rod 406 can be observed, so as to replace the fifth lead screw 403. By replacing the fifth lead screw 403 with different pitches, athletes with different arm lengths can be adapted for counting. For example, when the scale rod 406 only shows that the number of single bench presses of the athlete is 0.8, the fifth lead screw 403 can be replaced at this time. The pitch of the replaced fifth lead screw 403 is 1.2 times that of the previous one. By the difference between the existing number of bench presses and the daily bench press target number, it can directly reflect how many more bench presses the athlete needs to do to complete the daily target. Therefore, through the combined use of the quantity display component and the precise counting mechanism, athletes can be assisted to reach the daily physical training standard.
