[0037] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0038] Example 1:

[0039] This utility model provides a multifunctional shot put training adjustment aid, reference Figures 1 to 11As shown, the multifunctional shot put training adjustment aid includes a mounting support mechanism 1, a ratchet reduction mechanism 2, and a shot put throwing simulation mechanism 3.

[0040] The ratchet reduction mechanism 2 includes a ratchet assembly 21 and a pawl assembly 22. The ratchet assembly 21 is rotatably mounted on the mounting support mechanism 1. The ratchet assembly 21 has multiple reduction grooves 2111 arranged circumferentially. The pawl assembly 22 is adapted to the reduction grooves 2111. The shot put throwing simulation mechanism 3 is connected to the ratchet assembly 21 and rotates synchronously with the ratchet assembly 21.

[0041] During training, the user pushes the shot put throwing simulation mechanism 3, which performs the throwing action. The ratchet assembly 21 rotates forward relative to the pawl assembly 22. When the shot put throwing simulation mechanism 3 reaches a certain height, it falls back under the action of gravity. The ratchet assembly 21 rotates in the opposite direction, and the pawl assembly 22 is inserted into the circumferentially distributed deceleration grooves 2111, thereby slowing down the reverse speed of the ratchet assembly 21.

[0042] During the throwing motion of the shot put simulation mechanism 3, a small frictional force is generated between the ratchet assembly 21 and the pawl assembly 22, which is close to the air resistance encountered during the shot put throwing process, thus ensuring the simulation effect of shot put throwing.

[0043] During the return motion of the shot put simulation mechanism 3, the pawl assembly 22 and the circumferentially distributed deceleration grooves 2111 work together to effectively slow down the reverse rotation speed of the ratchet assembly 21, causing the shot put simulation mechanism 3 to fall slowly. This ensures the safety and reliability of the training process while maintaining the shot put training effect.

[0044] Example 2:

[0045] Example 2 is based on Example 1:

[0046] like Figures 1 to 11 As shown, the ratchet assembly 21 includes a reduction ratchet 211 and a ratchet support 212, and the pawl assembly 22 includes a reduction pawl 221 and a pawl elastic element 222.

[0047] The ratchet bracket 212 is rotatably mounted on the mounting support mechanism 1. The deceleration ratchet 211 is fixedly mounted on the ratchet bracket 212 and rotates synchronously with the ratchet bracket 212. All deceleration grooves 2111 are arranged circumferentially on the outer peripheral wall of the deceleration ratchet 211. The shot put throwing simulation mechanism 3 is connected to the ratchet bracket 212 and rotates synchronously with the ratchet bracket 212.

[0048] The deceleration pawl 221 is adapted to the deceleration groove 2111, and the pawl elastic element 222 is connected to the deceleration pawl 221. The pawl elastic element 222 is a spring, and its two ends are connected to the deceleration pawl 221 and the ratchet housing 23 respectively.

[0049] When the ratchet support 212 rotates in the forward direction, the deceleration ratchet 211 rotates relative to the deceleration pawl 221, and a small frictional force is generated between the two.

[0050] When the ratchet bracket 212 rotates in the opposite direction, the deceleration pawl 221 is inserted into the circumferentially distributed deceleration grooves 2111 in sequence under the elastic force of the pawl elastic element 222, thereby slowing down the rotation of the deceleration ratchet 211.

[0051] Specifically, as the deceleration ratchet 211 reverses, during the process of the deceleration pawl 221 switching between different deceleration slots 2111, the pawl elastic element 222 first deforms to generate elastic force, and then smoothly inserts into the next deceleration slot 2111 under the action of elastic force. This process is repeated, resulting in a significant deceleration effect.

[0052] As an optional implementation, the ratchet reduction mechanism 2 includes a ratchet housing 23. The inner peripheral wall of the ratchet housing 23 is provided with a plurality of mounting grooves 231 along the circumferential direction. The mounting grooves 231 are arranged radially along the reduction ratchet 211. The number of pawl assemblies 22 is the same as the number of mounting grooves 231, and the pawl assemblies 22 are arranged in the corresponding mounting grooves 231.

[0053] Specifically, the deceleration pawl 221 has a positioning hole, which is adapted to the pawl elastic element 222. One end of the pawl elastic element 222 is inserted into the positioning hole, and the other end is connected to the deceleration pawl 221.

[0054] The arrangement of multiple pawl assemblies 22 can further improve the reversing speed of the ratchet assembly 21.

[0055] As an optional implementation, the ratchet reduction mechanism 2 includes a housing, which is fixedly mounted on the mounting support mechanism 1.

[0056] The ratchet assembly 21, the pawl assembly 22, and the ratchet housing 23 are all located inside the housing. A mounting shaft is provided inside the housing. The ratchet bracket 212 is rotatably mounted on the mounting shaft via a bearing. The ratchet assembly 21 is rotatably mounted on the mounting support mechanism 1 via the housing.

[0057] The outer shell is provided with a clearance groove, and the connecting end of the ratchet bracket 212 passes through the clearance groove and exits the outer shell, and is connected to the shot put simulation mechanism 3.

[0058] The clearance groove has a certain opening, which does not affect the shot put throwing simulation mechanism 3 from performing the throwing action.

[0059] As an optional implementation, a locking wheel 213 is fixedly mounted on the ratchet bracket 212. The deceleration ratchet 211, ratchet bracket 212, and locking wheel 213 rotate synchronously. The locking wheel 213 has multiple locking grooves 2131 arranged circumferentially. The ratchet deceleration mechanism 2 includes a deadbolt assembly 24, which includes a deadbolt handle 241, a pull rod 242, and a locking pawl assembly. The pull rod 242 and the locking pawl assembly are both disposed inside the housing. One end of the deadbolt handle 241 is inserted into the housing along the clearance groove and is connected to the locking pawl assembly through the pull rod 242.

[0060] When training breaks or ends, the user moves the deadbolt handle 241, which drives the lever 242 to move, thereby moving the locking pawl assembly and engaging with the locking groove 2131, thus locking the relative position of the ratchet assembly 21 and preventing the shot put simulation mechanism 3 from falling.

[0061] When training resumes, the user reverses the locking handle 241, which causes the lever 242 to move in the opposite direction, thereby disengaging the locking pawl assembly from the locking groove 2131 and releasing the lock. At this point, shot put training can resume.

[0062] As an optional implementation, the locking claw assembly includes a first locking rod 243, a first locking claw 244, a second locking rod 245, and a second locking claw 246. The fixed end of the first locking rod 243 is hinged to the housing, and the connecting end of the first locking rod 243 is connected to the pull rod 242. The pull rod 242 is hinged to the first hinged end of the deadbolt handle 241. A first connecting seat is provided on the first locking rod 243, and the first locking claw 244 is provided on the first connecting seat. The fixed end of the second locking rod 245 is hinged to the housing, and the connecting end of the second locking rod 245 is connected to the second hinged end of the deadbolt handle 241. A second connecting seat is provided on the second locking rod 245, and the second locking claw 246 is provided on the second connecting seat. The second locking claw 246 and the first locking claw 244 are arranged opposite to each other.

[0063] The first locking rod 243, the second locking rod 245, the pull rod 242, and the anti-locking handle 241 cooperate to form a linkage structure, which can effectively ensure the action effect of the first locking pawl 244 and the second locking pawl 246. The relative arrangement of the first locking pawl 244 and the second locking pawl 246 can securely lock the locking wheel 213, thereby locking the ratchet assembly 21, and thus realizing the locking of the shot put throwing simulation mechanism 3.

[0064] The locking claw assembly also includes a locking elastic element 247, which is a tension spring. The two ends of the locking elastic element 247 are respectively connected to the first hinge end and the second locking rod 245.

[0065] The locking elastic element 247 can apply tension to the first locking rod 243 and the second locking rod 245, so that when locked, the first locking pawl 244 and the second locking pawl 246 can more firmly engage the locking groove 2131, further improving the locking effect.

[0066] As an optional implementation, the mounting support mechanism 1 includes a ground mounting frame 11, on which at least one mounting base 12 is provided, and the housing of the ratchet reduction mechanism 2 is mounted on the mounting base 12 by threaded fasteners.

[0067] In practical applications, ratchet reduction mechanism 2 and shot put simulation mechanism 3 can be set on multiple mounting bases respectively, so that multiple users can conduct shot put training at the same time.

[0068] As an optional implementation, the shot put simulation mechanism 3 includes a lever 31 and a counterweight 32.

[0069] The first end of the lever 31 is connected to the ratchet assembly 21, and the second end of the lever 31 is detachably provided with a throwing handle 33; the counterweight 32 is detachably provided on the lever 31 and is located near the throwing handle 33, and the number of counterweights 32 is at least one.

[0070] In practical applications, users can select and install the appropriate number of counterweights 32 according to their actual needs, thereby adjusting the training intensity.

[0071] Specifically, the counterweight 32 is a barbell plate, and the lever 31 has an installation section near its second end, on which the barbell plate is mounted.

[0072] As an optional implementation, the multifunctional shot put training adjustment aid includes a resistance deceleration mechanism 4, which includes a reducer 41, an adapter 44, and a resistance device. The resistance device, reducer 41, adapter 44, and ratchet assembly 21 are connected in sequence and coaxially arranged.

[0073] The setting of the resistance deceleration mechanism 4 further improves the reversal speed of the ratchet assembly 21, making the shot put throwing simulation mechanism 3 fall back more slowly. It works in conjunction with the ratchet deceleration mechanism 2 to effectively ensure the safety and reliability of the training process.

[0074] As an optional implementation, the resistance is configured as an electric resistance, which employs an electromagnetic powder clutch 42 or an electromagnetic damper.

[0075] In practical applications, the resistance of the electromagnetic powder clutch 42 can be adjusted by regulating the current.

[0076] Both the electromagnetic powder clutch 42 and the electromagnetic damper are existing technologies, and their detailed structures will not be described in detail here.

[0077] Example 3

[0078] The difference between Example 3 and Example 2 is that:

[0079] like Figures 12 to 14 As shown, the resistance device is configured as a manual resistance device, and the manual resistance device adopts a torque limiter 43.

[0080] Torque limiter 43 is existing technology, and its detailed structure will not be described in detail.
