Description

Technical Field

[0001] The utility model relates to the technical field of training equipment, in particular to a training device. Background Art

[0002] With the improvement of public health awareness, the demand for training equipment continues to grow. Users can use training equipment to enhance physical abilities, improve physical functions, promote recovery, etc.

[0003] In the related art, some training devices include multiple bodies, and adjacent bodies are rotatably connected. The user flips a part of the body to reduce the space occupied by the training device, thereby facilitating the storage of the training device; or the user flips a part of the body to adjust the angle between the bodies and change the training mode of the training device.

[0004] Although a locking mechanism is provided between the two rotationally connected bodies in these training devices, in the related art, the locking effect of the locking mechanism is poor, which affects the stability of the training device in use. Utility Model Content

[0005] The purpose of the embodiment of the utility model is to provide a training device, which can improve the locking strength of the locking mechanism and improve the stability of the training device.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A training device, comprising:

[0008] A first body, wherein a first locking seat is disposed at the rear end of the first body, and a rotating connection portion is disposed between the front end and the rear end of the first body;

[0009] A second body is rotatably connected to the rotating connection portion; a second locking seat is provided at one end of the second body;

[0010] A locking mechanism, disposed on the first locking seat or the second locking seat; the locking mechanism has a locking state and an unlocking state;

[0011] Wherein, when the locking mechanism is in the unlocked state, the second body can be rotated in the direction away from the first body to be adjusted to the open state; when the second body is in the open state and the locking mechanism is in the locked state, the locking mechanism blocks the side of the first locking seat away from the second locking seat and / or blocks the side of the second locking seat away from the first locking seat to maintain the locking limit between the first locking seat and the second locking seat, thereby limiting the first body and the second body from rotating close to each other.

[0012] Optionally, the training device is a resistance training device; the first body includes a support base and a stand, the stand is connected to the support base and extends upward from the support base; the first locking seat and the rotating connection part are arranged on the support base;

[0013] The second body is a pedal; when the locking mechanism is in the unlocked state, the pedal can be rotated in a direction away from the stand under the action of an external force to adjust to the open state, or rotated in a direction close to the stand to adjust to the folded state.

[0014] In this way, for resistance training equipment, when training force acts on the frame or pedal, there is a tendency for relative rotation between the frame and the pedal, which may be unstable. A locking mechanism is provided between the supporting base of the pedal and the frame to improve the stability of the resistance training equipment during training.

[0015] Optionally, when the second body is in the open state, the second body is located at the rear side of the first body, and the second locking seat and the first locking seat are distributed along the up-and-down direction.

[0016] In this way, the locking mechanism applies a locking force to the locking seat from a vertical direction, which has a better effect of preventing the machine body from turning around the horizontal axis and makes the locking more stable.

[0017] Optionally, the first locking seat protrudes backward relative to the first body.

[0018] In this way, the first locking seat extends backward from the first body, which can extend the force arm of the locking torque and improve the locking strength.

[0019] Optionally, the first locking seat protrudes backward relative to the first body, a notch is set at the front end of the second body, the second locking seat is set at the notch, and when the second body is in the open state and the locking mechanism is in the locked state, at least a portion of the first locking seat is located in the notch.

[0020] In this way, the front and rear ends of the two bodies are closer when locked, reducing the front and rear end gap between the two bodies.

[0021] Optionally, the second locking seat is located on an upper side of the first locking seat.

[0022] In this way, when the second body is turned over and folded, the second locking seat is not blocked by the first locking seat.

[0023] Optionally, when the second body is in the open state, the second locking seat is located on the upper side of the first locking seat;

[0024] The locking mechanism can be adjusted from the unlocked state to the locked state under the action of external force, so that the locking mechanism applies an upward force to the first locking seat, thereby allowing the first locking seat and the rear end of the first body to rotate around the rotating connection part at a preset angle, or allowing the first locking seat and the rear end of the first body to have a tendency to rotate around the rotating connection part.

[0025] In this way, when the locking mechanism locks the two bodies, under the action of the locking force, the rear end of the first body will rotate upward by a certain angle or have a tendency to rotate upward, and the locking effect is good. When the first body rotates upward by a certain angle, the rear end of the first body can be slightly lifted.

[0026] Optionally, when the second body is in the open state and the locking mechanism is in the unlocked state, a fitting gap D1 is provided between the upper side surface of the first locking seat and the lower side surface of the second locking seat, and the fitting gap D1 is greater than or equal to 0;

[0029] Wherein, when the second body is in an open state or a folded state, the first rear support member is used as a support member for the entire device, and the first rear support member contacts the ground to support the entire device.

[0030] Optionally, when the second body is in the open state and the locking mechanism is in the unlocked state, the first rear support member follows the rear end of the first body to rotate around the rotating connection portion at a preset angle, or has a tendency to rotate around the rotating connection portion.

[0031] In this way, when the second body is opened and the locking mechanism is locked, under the action of the locking force, the first rear support member moves upward or has a tendency to move upward, so that the first rear support member can leave the ground or has a tendency to leave the ground.

[0032] Optionally, the first rear support member is a roller, and the roller is rotatably mounted on the first locking seat or the first body.

[0033] Optionally, it further comprises a first front support member, the first front support member is arranged close to the front end of the first body, and the first front support member at least partially protrudes relative to the bottom surface of the first body;

[0034] Also included is a second rear support member, the second rear support member is disposed close to the rear end of the second body, and the second rear support member at least partially protrudes relative to the bottom surface of the second body;

[0035] When the second body is in the open state and the locking mechanism is in the locked state, the bottom of the first front support member and the bottom of the second rear support member are both tangent to the first plane, and there is a preset gap D between the first rear support member and the first plane, and the preset gap D is greater than or equal to;

[0036] When the locking mechanism is in the unlocked state, the second body can be rotated in a direction close to the first body under the action of external force to adjust to a folded state; when the second body is in the folded state, the bottom of the first front support member and the bottom of the first rear support member are both tangent to the second plane.

[0037] Optionally, the locking mechanism comprises a first locking block and a second locking block connected to each other;

[0039] Optionally, the locking mechanism further comprises a connecting rod, and two ends of the connecting rod are respectively connected to the first locking block and the second locking block;

[0040] When the second body is in the open state and the locking mechanism is in the locked state, the connecting rod is at a locking angle or a locking position, and the first locking seat and the second locking seat are clamped between the first locking block and the second locking block;

[0041] When the second body is in the open state and the locking mechanism is in the unlocked state, the connecting rod is at an unlocking angle or unlocking position, and the second locking block can be disengaged from the second locking seat during the process of the second body rotating toward the first body, or the first locking block can be disengaged from the first locking seat during the process of the second body rotating toward the first body;

DETAILED DESCRIPTION

[0069] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0070] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected" and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0072] In the related art, some training devices have rotating connections between the bodies, so that they can be folded and stored when the training device is not needed, or the training mode can be adjusted by changing the angle between the bodies. Although these training devices are provided with locking mechanisms, the locking force of these locking mechanisms is limited. When the two bodies are rotated open, if the user applies a large force to one body, the whole device may shake due to insufficient locking force, or the locking may fail and the body may flip.

[0073] Based on this, the present application provides a training device, in which the hinge point between the bodies is at a certain distance from the locking point between the bodies, which can increase the locking torque of the locking mechanism, improve the locking strength of the locking mechanism between the two bodies, and improve the stability and safety of the training device. In addition, under the same locking strength requirements, by increasing the locking torque of the locking mechanism, the hinge point is kept at a certain distance from the locking point as much as possible, which can reduce the locking force requirements of the locking mechanism.

[0074] The training device of the present application can be a strength training device, an aerobic training device, a balance training device, a rehabilitation training device or a comprehensive training device. In some embodiments, the user can use the training device to do a variety of power training movements such as fly training movements, bench press training movements, deadlift training movements, and rowing training movements.

[0075] Please refer to Figures 1 to 22 , the structure of the training device is described below.

[0076] In order to easily understand the positional relationship between the components inside the training device, the y direction indicates the front-to-back direction of the training device, the x direction indicates the left-to-right direction of the training device, and the z direction indicates the up-to-down direction of the training device, and the x, y, and z directions are perpendicular to each other. It should be noted that the front-to-back, left-to-right, and up-to-down directions are only used to describe the relative positional relationship between the components in the training device, and are not used as a limitation on the present application. When the first body 10 of the training device is placed on the ground, the user stands behind the first body 10, and the user faces the first body 10, the front-to-back, left-to-right, and up-to-down directions of the training device are consistent with the front-to-back, left-to-right, and up-to-down directions of the user.

[0077] Please continue to refer to Figures 1 to 22 The training device includes a first body 10, a second body 20, and a locking mechanism 50.

[0078] The second body 20 is rotatably connected to the first body 10 via a rotating shaft 60. The first body 10 and the second body 20 are different parts of the training device. When there are different requirements for the training device, the second body 20 can be adjusted to a suitable angle according to the requirements. The locking mechanism 50 is used to lock the relative rotation of the second body 20 and the first body 10.

[0079] Among them, Figure 2 As shown, the first body 10 is provided with a rotating connection portion 101. Fig.10 , Fig.12 , Figures 15 to 18 As shown, the second body 20 is rotatably connected to the rotating connection portion 101 to achieve rotatable connection between the second body 20 and the first body 10 .

[0080] Optionally, the second body 20 has an open state (eg Fig.10 , Fig.12 , Fig.15 , Fig.16 , Fig.19 , Fig. 20 as shown) and the folded state (as Fig.13 As shown). For example, when the user needs to use the training device, the second body 20 can be rotated in a direction away from the first body 10, so that the second body 20 is rotated to adjust to an open state, and the user can use the first body 10 and the second body 20 for strength training. When the user does not need to use the training device, the second body 20 can be rotated in a direction close to the first body 10 and away from the ground, so that the second body 20 is rotated to adjust to a folded state, so as to reduce the occupied space of the entire training device and facilitate storage. Of course, in other embodiments, by rotating the second body 20 relative to the first body 10, the angle between the second body 20 and the first body 10 can be changed to adapt to different training usage requirements.

[0081] The locking mechanism 50 is used to keep the second body 20 in an open state. When the second body 20 is in the open state, the locking mechanism 50 is used to limit the relative rotation between the second body 20 and the first body 10, so that the second body 20 and the first body 10 remain stable.

[0082] The inventors have discovered that when the second body 20 is in the open state, if the locking force of the locking mechanism 50 between the second body 20 and the first body 10 is insufficient, the device may shake during training, affecting the training effect.

[0083] Exemplarily, the training device is a resistance training device. When the user uses the training device for resistance training, the second body 20 is in an open state. The user stays on the second body 20 by standing, sitting, kneeling, lying, etc. The main body weight of the user acts on the second body 20. The first body 10 is provided with resistance members such as resistance bands. The user acts on the resistance members by hand pulling, foot hooking, etc., pulling the resistance members close to the user's body to perform resistance training. Since the main weight of the user acts on the second body 20, the position of the second body 20 is stable, and the pulling force of the user on the resistance member of the first body 10 makes the first body 10 tend to flip in the direction close to the user and the second body 20. At this time, if the locking force of the locking mechanism 50 between the second body 20 and the first body 10 is insufficient, it may cause the first body 10 to shake or rotate, affecting the stability of the training action, or causing safety hazards.

[0084] Of course, in other cases, when the second body 20 is in the open state and the user uses the training equipment, the second body 20 may also tend to flip toward the direction close to the first body 10. The shaking or rotation of the second body 20 may also affect the training effect or safety hazards.

[0085] In order to allow the user to have a better user experience when the second body 20 is in the open state, in this application, the first body 10 is provided with a first locking seat 30, and the second body 20 is provided with a second locking seat 40. The locking mechanism 50 has a locking state (such as Fig.11 as shown) and unlocked state (as shown Fig.17 , Fig.18 When the locking mechanism 50 is in the unlocked state, the second body 20 can be rotated away from the first body 10 under the action of an external force to adjust to the open state, or rotated toward the first body 10 under the action of an external force to adjust to the folded state. Figures 15 to 18 When the second body 20 is in the open state, the locking mechanism 50 can be adjusted from the unlocked state to the locked state under the action of external force. Fig.10 , Fig.11When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the locking mechanism 50 blocks the side of the first locking seat 30 away from the second locking seat 40, and / or the locking mechanism 50 blocks the side of the second locking seat 40 away from the first locking seat 30, so as to maintain the locking limit between the first locking seat 30 and the second locking seat 40, and limit the relative rotation of the two locking seats around the hinge axis of the two bodies, thereby limiting the relative rotation of the first body 10 and the second body 20. Optionally, when the second body 20 is opened and the locking mechanism 50 is locked, the first body 10 and the second body 20 are limited to rotate close to each other. It should be noted that limiting the rotation of the first body 10 and the second body 20 close to each other can refer to limiting the rotation of the second body 20 in the direction close to the first body 10 under the action of an external force, and can also refer to limiting the rotation of the first body 10 in the direction close to the second body 20 under the action of an external force.

[0086] In some embodiments, when the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the first locking seat 30 abuts against the second locking seat 40. In other embodiments, when the second body 20 is in the open state and the locking mechanism 50 is in the locked state, there is a gap between the first locking seat 30 and the second locking seat 40.

[0087] Please continue to refer to Figures 10 to 12 In order to enhance the locking effect, when the second body 20 is in the open state, the rotation connection part 101 of the first body 10 is located on the side of the first locking seat 30 away from the second body 20. Optionally, the front end of the first body 10 is the first front end, the rear end of the first body 10 is the first rear end, the first locking seat 30 is arranged at the first rear end, and the rotation connection part 101 is arranged between the first front end and the first rear end. In the present application, the position of the rotation connection between the second body 20 and the first body 10 (i.e., the hinge point) and the locking position (locking point) of the locking mechanism 50 are arranged at intervals, so that the distance R between the hinge point and the locking point can be extended to a large extent, which is equivalent to increasing the locking force arm that prevents the relative rotation between the first body 10 and the second body 20. Under the condition of the same locking force, the increase of the locking force arm can increase the locking torque, thereby strengthening the locking strength of the locking mechanism 50 and improving the locking effect.

[0088] The training device of the present application has the following effects:

[0089] First, the second body 20 is rotatably connected to the first body 10 , and the state of the second body 20 can be adjusted by rotating the second body 20 to meet different user needs.

[0090] Second, compared with the solution of setting the first locking seat 30 on the left and right side walls of the first body 10, and compared with the solution of setting the part of the first body 10 for rotational connection with the second body 20 on the left and right sides of the first locking seat 30, in the present application, the first locking seat 30 of the first body 10 is set at the rear end of the first body 10, and the rotation connection part 101 is configured between the front end and the rear end of the first body 10, so that the distance between the locking position between the two bodies and the hinged position between the two bodies can be extended, and the force arm corresponding to the locking torque of the locking mechanism 50 to prevent the relative rotation between the first body 10 and the second body 20 is increased, thereby improving the locking strength and improving the training stability and safety.

[0091] Third, the first locking seat 30 is set at the rear end of the first body 10, and the second locking seat 40 is correspondingly set at the front end of the second body 20. When the second body 20 is in an open state and the locking mechanism 50 is in a locked state, the first locking seat 30 and the second locking seat 40 are located in the middle of the two bodies, and can provide locking force from the middle area, and the locking effect is good.

[0092] In one embodiment, optionally, when the second body 20 is in an open state, the angle between the upper surface of the second body 20 and the upper surface of the first body 10 is a first angle; when the second body 20 is in a folded state, the angle between the upper surface of the second body 20 and the upper surface of the first body 10 is a second angle; the second angle is smaller than the first angle.

[0093] In one embodiment, when the second body 20 is in the open state, it is in a horizontal state, and when the second body 20 is in the folded state, it is in a vertical state. In other embodiments, when the second body 20 is in the folded state, the first body 10 and the second body 20 are against each other.

[0094] Optionally, the training device is a resistance training device.

[0095] like Figure 1 , Figure 2 As shown, the first body 10 includes a support base 11 and a stand 12, the stand 12 is connected to the support base 11 and extends upward from the support base 11; the first locking seat 30 and the rotating connection part 101 are disposed on the support base 11. Figures 3 to 6 As shown, the second body 20 is a pedal, and when the pedal is in the open state, it provides a user standing area, and the user can stand on the pedal during training. When the locking mechanism 50 is in the unlocked state, the pedal can be rotated away from the stand 12 under the action of an external force to adjust to the open state, or rotated toward the stand 12 to adjust to the folded state.

[0096] In one embodiment, the pedal includes a pedal body 21 and a connecting arm 22. The connecting arms 22 are respectively extended forward on the left and right sides of the front end of the pedal body 21, so as to be hinged to the rotating connection part 101 between the front and rear ends of the first body 10 through the connecting arm 22, thereby achieving the effect of extending the distance R between the locking point of the locking mechanism 50 and the hinge point between the bodies.

[0097] Optionally, a resistance member (such as a resistance rope) is provided on the stand 12. When the second body 20 is in the open state, the user can stand on the second body 20 and pull the resistance member on the first body 10 to perform fitness training movements such as bent-over fly, standing rowing, and seated rowing. At this time, the stand 12 of the first body 10 is subjected to a pulling force in the direction of the user. Fig.12 In the figure, F1 indicates the pulling force on the stand 12, M1 indicates the turning torque M1 on the first body 10 to turn backward; F2 in the figure indicates the locking force F2 generated by the locking mechanism 50 and the locking seat, or the adjacent locking seats, R indicates the distance R between the locking point between the bodies and the hinge point between the bodies, and M2 indicates the locking torque M2 provided by the locking mechanism 50. The turning torque M1 is offset by the locking torque M2 to keep the first body 10 stable and prevent it from rotating. By arranging the rotating connection part 101 between the first front end and the first rear end, the force arm R can be increased as much as possible to increase the locking torque M2 and improve the locking strength.

[0098] It is understandable that when the stand 12 is subjected to a thrust during user training, the increase in the lever arm R also increases the locking torque M2 and improves the locking strength.

[0099] In other embodiments, the first body 10 may not be provided with the stand 12, and the first body 10 and the second body 20 may also be two pedals. When the user uses the training device, the second body 20 is in an open state, and the user is located on one pedal (the second body 20) in a sitting or lying position, and a pull rope and a pull ring are provided on the other pedal (the first body 10). The user pulls the stretch rope in a direction close to the body by hand or foot hooking the pull ring to perform resistance training. For this type of dual-pedal training device, the locking mechanism 50 of the present application also has a high locking strength.

[0100] In other embodiments, the first body 10 includes a stand 12, and the second body 20 is a training chair.

[0101] Please refer to Fig.10 , Fig.13 , Fig.17 , Fig.18The second body 20 is rotatably connected to the first body 10 via a rotating shaft 60, which is disposed at the rotating connection portion 101 of the first body 10 and extends in the left-right direction. When the locking mechanism 50 is in the locked state, the second body 20 can rotate backward under the action of an external force to adjust to the open state or rotate forward to adjust to the folded state. When the second body 20 is in the open state, the second body 20 is located at the rear side of the first body 10.

[0102] Please continue to refer to Fig.10 , Fig.11 In one embodiment, when the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the first locking seat 30 and the second locking seat 40 are arranged one above the other, so that the locking mechanism 50 applies a locking force in the up-down direction to restrict the first body 10 from flipping backward and / or restrict the second body 20 from flipping forward. In this embodiment, the two locking seats are distributed in the up-down direction, and the locking mechanism 50 applies a locking force from the upper side and / or the lower side of the two locking seats. In this way, based on the locking of the locking mechanism 50, when the contact surfaces between the two locking seats and the contact surfaces between the locking seats and the locking mechanism 50 are against each other, the first body 10 can be restricted from flipping backward and / or the second body 20 can be restricted from flipping forward. Fig.12 As shown, a locking force F2 substantially perpendicular to the ground is generated, that is, the locking force F2 is substantially perpendicular to the line between the first locking seat 30 and the rotating connection portion 101. At this time, the locking torque M2 generated based on the locking force F2 is larger, which can effectively offset the training force exerted by the user on the first body 10 or the second body 20 during training, thereby ensuring the locking strength. On the other hand, when the first locking seat 30 and the second locking seat 40 are distributed one above the other, when the first body 10 or the second body 20 has a tendency to flip toward the other body, the contact surface between the two locking seats is large, and one locking seat or locking mechanism 50 can be more stably blocked on the rotation path of the other locking seat, and the locking is stable.

[0103] In some other embodiments, the two locking seats are distributed along the front-to-back direction, and the front and rear locking seats are inserted in the front-to-back direction, and the locking mechanism 50 provides a locking force extending in the front-to-back direction, so that the two locking seats are kept inserted in the front-to-back direction to achieve locking. Although this locking method can also achieve the locking effect, when the machine body is subjected to the training force and has a tendency to flip, the reaction force generated between the contact surfaces of the two locking seats and the angle between the contact surfaces are small. When the training force on the machine body is large, the contact surfaces of the two locking seats are prone to relative sliding, so that the two locking seats are separated from each other and the locking fails. In the aforementioned embodiment, the two locking seats are distributed along the up-down direction, and the locking mechanism 50 is pressed against the upper side of the upper locking seat and / or the lower side of the lower locking seat. When the machine body is subjected to the training force and has a tendency to flip, the reaction force generated between the contact surfaces of the two locking seats is basically perpendicular to the contact surface, and the first locking seat 30 and the second locking seat 40 are not prone to relative sliding, which can more efficiently offset the torque caused by the training force acting on the machine body.

[0104] Optionally, a first contact surface (not marked in the figure) is formed on the side of the first locking seat 30 close to the second locking seat 40, and a second contact surface (not marked in the figure) is formed on the side of the second locking seat 40 close to the first locking seat 30. When the second body 20 is in an open state and the locking mechanism 50 is in a locked state, the first contact surface abuts against the second contact surface.

[0105] Please refer to Figure 1 , Figure 2 , Fig.10 , Fig.11 In one embodiment, when the second body 20 is in the open state, the first locking seat 30 and the second locking seat 40 are distributed in the up-down direction. On this basis, the first locking seat 30 is configured to extend and protrude backward relative to the first body 10. Optionally, the first body 10 includes a support base 11, which is used as a motor compartment. The support base 11 is provided with a motor, a steel wire rope or other devices for providing a resistance source and a power source. The first locking seat 30 extends backward from the outer shell of the support base 11 to extend out of the support base 11. The first locking seat 30 extends backward and protrudes backward relative to the support base 11, so that the distance between the hinge point of the second motor and the first motor and the locking point can be largely developed, which is equivalent to increasing the force arm of the locking torque M2 that prevents the relative rotation between the two bodies, thereby improving the locking effect.

[0106] Optionally, refer to Figure 5The front end of the second body 20 is provided with a notch, and the second locking seat 40 is provided at the notch. When the second body 20 is in the open state, the first locking seat 30 can at least partially fit into the notch, and the two locking seats are distributed in the up-down direction. The notch is provided to avoid the two locking seats occupying the front and rear spaces and causing gaps when the second body 20 is opened, so that the rear side of the first body 10 and the front side of the second body 20 are close to each other, and the gap between the two bodies is reduced, which does not affect the appearance or use of the training device.

[0107] In other embodiments, the second body 20 may not be provided with a notch, and the second locking seat 40 may be provided to extend forwardly and protrude relative to the second body 20, so that the two locking seats are distributed up and down when the second body 20 is opened and locked. Alternatively, in other embodiments, the first body 10 is provided with a notch, the first locking seat 30 is provided at the notch of the first body 10, the second locking seat 40 protrudes forward relative to the second body 20, and when locked, the second locking seat 40 extends into the notch of the first body 10, so that the two locking seats are distributed up and down when the second body 20 is opened and locked.

[0108] Please continue to refer to Fig.11 , Fig.18 , Fig. 22 In one embodiment, when the second body 20 is in the open state, the first locking seat 30 and the second locking seat 40 are distributed in the up-down direction, and the second locking seat 40 is located on the upper side of the first locking seat 30. At this time, since the hinge point between the second body 20 and the first body 10 is located in the front side of the first locking seat 30, when the locking mechanism 50 is in the unlocked state, if the second body 20 needs to be switched from the open state to the folded state, the second body 20 can rotate forward and upward around the hinge point on the front side, and the second locking seat 40 moves upward accordingly. The first locking seat 30 does not block the movement path of the second locking seat 40, and the first locking seat 30 does not hinder the folding and storage of the second body 20.

[0109] In other embodiments, when the second body 20 is in the open state, the first locking seat 30 is located on the upper side of the second locking seat 40. At this time, the second body 20 can be moved downward by a certain distance and then flipped over so that the second locking seat 40 avoids the first locking seat 30 on the flipping path and does not hinder the folding and storage of the second body 20. Alternatively, other avoiding methods can be used to prevent the first locking seat 30 from blocking the second locking seat 40 when the second body 20 needs to be flipped over.

[0110] In one embodiment, when the second body 20 is in an open state, the second locking seat 40 is located on the upper side of the first locking seat 30, and the locking mechanism 50 can be adjusted from an unlocked state to a locked state under the action of an external force, so that the locking mechanism 50 applies an upward force to the first locking seat 30, so that the first locking seat 30 and the rear end of the first body 10 can rotate to a preset angle, or the first locking seat 30 and the rear end of the first body 10 have a tendency to rotate.

[0111] The first locking seat 30 and the rear end of the first body 10 can rotate at a preset angle, which means that the first locking seat 30 and the rear end of the first body 10 rotate at a certain angle around the rotating connection portion 101 or the position where the front end of the first body 10 contacts the ground as a fulcrum. The first locking seat 30 and the rear end of the first body 10 have a tendency to rotate, which means that the first locking seat 30 and the rear end of the first body 10 have a tendency to rotate around the rotating connection portion 101 or the position where the front end of the first body 10 contacts the ground as a fulcrum. Fig. 20 In the embodiment, the point where the front end of the first body 10 contacts the ground is the point where the first front support member 72 contacts the ground.

[0112] Optionally, the locking mechanism 50 may also apply an upward force to the first locking seat 30 , thereby applying an upward force to the second locking seat 40 through the first locking seat 30 , so that the second locking seat 40 and the front end of the second body 20 are moved upwardly together.

[0113] An embodiment is provided below to illustrate the manner in which the first locking seat 30 and the rear end of the first body 10 are brought together upward: the locking mechanism 50 includes a first locking block 51, a connecting rod 53, and a second locking block 52. The first locking block 51 and the second locking block 52 are connected to both ends of the connecting rod 53. When the second body 20 is in an open state and the locking mechanism 50 is in a locked state, the second locking block 52 is located on the upper side of the second locking seat 40, the second locking seat 40 is located on the upper side of the first locking seat 30, and the first locking block 51 is located on the lower side of the first locking seat 30. When locking, by narrowing the gap between the bottom end of the second locking block 52 and the top end of the first locking block 51, the first locking block 51 can push the first locking seat 30 upward, so that the first locking seat 30 and the rear end of the first body 10 can be slightly lifted upward with the point where the front end of the first body 10 contacts the ground as a fulcrum. At this time, the rear end of the first body 10 can be slightly higher than the front end of the first body 10. Fig.18 , Fig. 22 When the second body 20 is opened and the locking mechanism 50 is in the unlocked state, there is a matching gap D1 between the first locking seat 30 and the second locking seat 40, and D1 is greater than or equal to 0; Fig.11After the second body 20 is opened and the locking mechanism 50 is locked, the first locking seat 30 is pulled upward and moved closer to each other, so that the gap between the first locking seat 30 and the second locking seat 40 is reduced or eliminated, and the first locking seat 30 and the second locking seat 40 are as close or close as possible.

[0114] It should be noted that when the second body 20 is opened and the locking mechanism 50 is in the unlocked state, when D1 is greater than 0, the first locking seat 30 and the second locking seat 40 are not in contact with each other. During the locking process, the locking mechanism applies force to make the two locking seats resist each other and exert force on each other. When the second body 20 is opened and the locking mechanism 50 is in the unlocked state, when D1 is equal to 0, the first locking seat 30 and the second locking seat 40 are just lightly overlapped or only in contact with each other. During the locking process, the locking mechanism applies force to make the two locking seats fit tightly, squeeze the locking seats, and cause the locking seats to be slightly displaced or slightly deformed.

[0115] It should be noted that during the use of the training equipment, the training equipment is placed on the ground. The training equipment is generally designed with support structures at certain locations for contact with the ground. However, the ground may not be flat everywhere. If the overall height of the support structure of the training equipment is not high, and there are abnormal protrusions on the ground in the area where the support structure is not designed, the bottom of the training equipment without the support structure may touch the ground. At this time, the original support structure of the training equipment may not be able to touch the ground, causing the entire training equipment to shake. Therefore, when the training equipment is in use, there are certain requirements for the flatness of the ground.

[0116] It can be understood that in the embodiment of the present application, while the locking mechanism 50 locks the second locking seat 40 and the first locking seat 30, the locking force of the locking mechanism 50 can slightly lift the rear end of the first body 10 and / or the front end of the first body 10, thereby avoiding or reducing the possibility of the rear end of the first body 10 and the front end of the second body 20 contacting the ground, allowing the support structure at the front end of the first body 10 and the support structure at the rear end of the second body 20 to more stably contact the ground, thereby reducing the training equipment's requirements for the venue ground and improving applicability.

[0117] In other words, when the second body 20 is in the open state, the locking action of the locking mechanism 50 can not only limit the relative rotation between the first body 10 and the second body 20, but also increase the locking strength. In addition, the locking action of the locking mechanism 50 can also allow the support structures at the bottom of the first body 10 and the second body 20 to touch the ground better and more stably, making the device more stable when in use.

[0118] Of course, in other embodiments, when the second body 20 is in the open state and the locking mechanism 50 of the training device is locked, the locking mechanism 50 may not push the first locking seat 30 and the rear end of the first body 10 upward.

[0119] Optionally, when the second body 20 is in the open state and the locking mechanism 50 is in the unlocked state, there is a matching gap D1 between the upper side of the first locking seat 30 and the lower side of the second locking seat 40, and the matching gap D1 is greater than 0. When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the locking mechanism 50 has at least a first locking block 51, and the first locking block 51 is located below the first locking seat 30. When the locking mechanism 50 is locked, the first locking block 51 exerts an upward force on the first locking seat 30 disposed at the bottom, so that the first locking seat 30 at the bottom moves upward and closes to the second locking seat 40. In this way, when the locking mechanism 50 locks the two locking seats, the locking mechanism 50 can slightly lift the first locking seat 30 at the bottom and its surrounding structures upward.

[0120] Please refer to Figure 1 , Figure 2 , Fig.13 , Fig.14 In one embodiment, a first rear support member 71 is disposed at the rear end of the first body 10, and at least a portion of the first rear support member 71 protrudes relative to the bottom surface of the first body 10. The first rear support member 71 is used to contact the ground when the second body 20 is in a folded state to support the first body 10.

[0121] Optionally, the first rear support member 71 is disposed close to the first locking seat 30 so that when the second body 20 is in the open state and the locking mechanism 50 is adjusted from the unlocked state to the locked state under the action of an external force, Fig.11 As shown, the first locking block 51 of the locking mechanism 50 exerts an upward force on the first locking seat 30, so that:

[0122] The first rear support member 71 follows the rear end of the first body 10 to rotate around the rotating connection portion 101 at a preset angle (i.e., a certain angle); or, the first rear support member 71 has a tendency to rotate around the rotating connection portion 101; or, the first rear support member 71 follows the rear end of the first body 10 to rotate around the position where the front end of the first body 10 contacts the ground as a fulcrum at a preset angle (i.e., a certain angle); or, the first rear support member 71 has a tendency to rotate around the position where the front end of the first body 10 contacts the ground as a fulcrum.

[0123] For example, when the second body 20 is opened and the locking mechanism 50 is locked, the first locking block 51 exerts an upward force on the first locking seat 30, so that the first locking seat 30 and the first rear support member 71 located near the first locking seat 30 are lifted upward by a certain distance, so that the first rear support member 71 is slightly off the ground. In this way, when the training device is in use and the second body 20 is in an open state, the middle is slightly arched, reducing the probability of the first rear support member 71 near the middle area touching the ground and causing instability, so that the front end of the first body 10 and the rear end of the second body 20 are kept touching the ground as much as possible. When the training device is stored and the second body 20 is in a folded state, the locking mechanism 50 is in an unlocked state, and the first rear support member 71 can touch the ground to support the first body 10.

[0124] Optionally, the first rear support member 71 is a roller. When the training device is in use and the second body 20 is in an open state, the first rear support member 71 can be kept away from the ground as much as possible to avoid instability caused by the roller on the rear side of the first body 10 touching the ground. When the training device is stored and the second body 20 is in a folded state, the roller on the rear side of the first body 10 can touch the ground to facilitate pushing the entire training device to move it to a convenient storage position, which is more convenient for users to use. Compared with the solution in which no roller is provided under the first body 10, the solution of this embodiment can improve the flexibility of the movement of the training device and take into account the stability of the training device when it is used.

[0125] In other embodiments, the first rear support member 71 may also be merely a non-rotatable fixed support foot.

[0126] In other embodiments, the first rear support member 71 may not be disposed at the rear end of the first body 10 .

[0127] In one embodiment, the first rear support member 71 is a roller, and the first rear support member 71 is rotatably mounted on the first locking seat 30. In other embodiments, the first rear support member 71 is a roller, and the first rear support member 71 is rotatably mounted on the first body 10.

[0128] Please continue to refer to Figures 10 to 22 In one embodiment, the training device includes a first rear support member 71, a first front support member 72, and a second rear support member 73. The first front support member 72 is disposed close to the front end of the first body 10, and at least a portion of the first front support member 72 protrudes relative to the bottom surface of the first body 10. The second rear support member 73 is disposed close to the rear end of the second body 20, and at least a portion of the second rear support member 73 protrudes relative to the bottom surface of the second body 20.

[0129] like Fig.16 , Fig.18As shown, when the second body 20 is in the open state and the locking mechanism 50 is in the unlocked state, the bottom of the first front support member 72, the bottom of the first rear support member 71, and the bottom of the second rear support member 73 are all tangent to the first plane S1. At this time, there is a gap between the first locking seat 30 and the second locking seat 40.

[0130] like Fig.10 , Fig.11 As shown, when the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the bottom of the first front support member 72 and the bottom of the second rear support member 73 are both tangent to the first plane S1. At this time, the first locking seat 30 and the second locking seat 40 are against each other, and there is a preset gap D2 between the first rear support member 71 and the first plane S1, and the preset gap D2 is greater than or equal to 0. When the training device is placed on a flat ground, the second plane S2 is the ground, D2 is greater than 0, the first rear support member 71 is off the ground, and the training device is supported by the first front support member 72 on the front side and the second rear support member 73 on the rear side contacting the ground.

[0131] like Fig.13 , Fig.14 As shown, when the second body 20 is in the folded state, the bottom of the first front support member 72 and the bottom of the first rear support member 71 are tangent to the second plane S2. When the training device is placed on a flat ground, the second plane S2 is the ground. At this time, the second body 20 is folded and stored, and the first front support member 72 at the front end of the first body 10 and the first rear support member 71 at the rear end touch the ground.

[0132] Optionally, in order to improve the stability of the training device during use, the first front support member 72 and the second rear support member 73 are fixed support feet.

[0133] In other embodiments, one of the first front support member 72 and the second rear support member 73 may also be a roller.

[0134] In other embodiments, the first front support member 72 may be eliminated, and only the first rear support member 71 and the second rear support member 73 are provided.

[0135] The configuration of the locking mechanism 50 is described below.

[0136] Please refer to Figure 7 , Figure 5 , Fig.11 The locking mechanism 50 includes a first locking block 51 and a second locking block 52 connected to each other. Fig.11When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the first locking seat 30 and the second locking seat 40 are located between the first locking block 51 and the second locking block 52, so that the two locking seats are locked from both sides by the two locking blocks. In this way, each locking seat is in a state where one side is restricted by one locking block and the other side is restricted by the other locking seat, which has a good effect on limiting movement and rotation of the locking seat, and improves the locking strength of relative rotation between the two bodies. Among them, the first locking block 51 abuts or has a clearance fit with the first locking seat 30, the second locking block 52 abuts or has a clearance fit with the second locking seat 40, and the first locking seat 30 abuts or has a clearance fit with the second locking seat 40.

[0137] Optionally, the first locking block 51 abuts against the first locking seat 30, the first locking seat 30 abuts against the second locking seat 40, and the second locking seat 40 abuts against the second locking block 52. When the locking mechanism 50 is locked, the two locking seats are pressed toward the middle by the locking blocks on both sides, and the locking effect is reliable. In this way, when the training equipment is in use, whether the first body 10 is subjected to the training force or the second body 20 is subjected to the training force and has a tendency to flip, the locking blocks on both sides can apply locking force from both sides, and the rotation of the first body 10 and the second body 20 can be stably locked, and the locking effect is reliable.

[0138] In other embodiments, only one locking block may be provided, and the second locking seat 40 may be clamped from both sides by the first locking seat 30 and the locking block, or the first locking seat 30 may be clamped from both sides by the second locking seat 40 and the locking block to provide a locking effect.

[0139] The following description will continue with the example that the locking mechanism 50 includes a first locking block 51 and a second locking block 52. The locking mechanism 50 also includes a connecting rod 53, and both ends of the connecting rod 53 are connected to the first locking block 51 and the second locking block 52 respectively.

[0140] Several configurations of the locking mechanism 50 are provided below, so that the second body 20 can be folded toward the direction close to the first body 10 after the locking mechanism 50 is unlocked.

[0141] Locking mechanism 50 setting method 1:

[0142] The connecting rod 53 has a locking angle and an unlocking angle, and the connecting rod 53 is rotatably mounted on the second locking seat 40 .

[0143] When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the connecting rod 53 is at the locking angle, and the first locking seat 30 and the second locking seat 40 are clamped between the first locking block 51 and the second locking block 52. When the second body 20 is in the open state and the locking mechanism 50 is in the unlocked state, the rotating connecting rod 53 is rotated to the unlocking angle, so that the first locking block 51 can be separated from the first locking seat 30 during the process of the second body 20 rotating toward the first body 10.

[0144] The second setting method of the locking mechanism 50:

[0145] The connecting rod 53 has a locking angle and an unlocking angle, and the connecting rod 53 is rotatably mounted on the first locking seat 30 .

[0146] When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the connecting rod 53 is at the locking angle, and the first locking seat 30 and the second locking seat 40 are clamped between the first locking block 51 and the second locking block 52. When the second body 20 is in the open state and the locking mechanism 50 is in the unlocked state, the rotating connecting rod 53 is rotated to the unlocking angle, so that the second locking block 52 can be separated from the second locking seat 40 during the process of the second body 20 rotating in the direction of the first body 10.

[0147] The third setting method of the locking mechanism 50:

[0148] The connecting rod 53 has a locking position and an unlocking position, and the connecting rod 53 is movably mounted on the second locking seat 40 .

[0149] When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the connecting rod 53 is in the locked position, and the first locking seat 30 and the second locking seat 40 are clamped between the first locking block 51 and the second locking block 52. When the second body 20 is in the open state and the locking mechanism 50 is in the unlocked state, the rotating connecting rod 53 moves to the unlocked position, so that the first locking block 51 can be separated from the first locking seat 30 during the process of the second body 20 rotating in the direction of the first body 10.

[0150] Locking mechanism 50 arrangement mode 4:

[0151] The connecting rod 53 has a locking position and an unlocking position, and the connecting rod 53 is movably mounted on the first locking seat 30 .

[0152] When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the connecting rod 53 is located at the locking position, and the first locking seat 30 and the second locking seat 40 are clamped between the first locking block 51 and the second locking block 52. When the second body 20 is in the open state and the locking mechanism 50 is in the unlocked state, the rotating connecting rod 53 moves to the unlocking position, so that the second locking block 52 can disengage from the second locking seat 40 during the rotation of the second body 20 towards the first body 10.

[0153] In the third and fourth settings of the locking mechanism 50, a first locking hole can be provided in the first locking block 51, a second locking hole can be provided in the second locking block 52, and the connecting rod 53 passes through the first locking hole and the second locking hole. Both locking holes are designed to include a large hole portion and a small hole portion communicating with the large hole portion. In this way, when it is necessary to keep the second body 20 in the open state, the connecting rod 53 is translated to the positions of the two small hole portions. At this time, the two locking blocks cannot pass through the two locking holes. When it is necessary to turn the second body 20 upward and forward for storage, the connecting rod 53 is translated to the two large holes, so that when the user turns the second body 20, the locking blocks can pass through the large hole portion and disengage from the locking seat.

[0154] In addition to the foregoing first to fourth settings of the locking mechanism 50, in other embodiments, the first locking block 51, the connecting rod 53, and the second locking block 52 of the locking mechanism 50 can also be the structures after the similar "凵" - shaped structure is folded by 90 degrees. When it is necessary to lock the two locking seats, the locking mechanism 50 is buckled on the first locking seat 30 and the second locking seat 40 from the left or right. When it is necessary to turn the second body 20 upward, the locking mechanism 50 is then pulled out from the locking seat laterally. Or, in other embodiments, when it is necessary to turn the second body 20 upward, the locking mechanism 50 can be disassembled by loosening the screws, so that the two locking blocks are removed from both sides of the two locking seats to adjust the locking mechanism 50 to the unlocked state.

[0155] Please continue to refer to Fig.11 、 Fig.18 、 Fig. 22 In one embodiment, on the basis of the first setting of the locking mechanism 50, the training device is configured such that when the second body 20 is in the open state, the second locking seat 40 is located above the first locking seat 30, the second locking block 52 is located above the second locking seat 40, and the first locking block 51 is located below the first locking seat 30. And, the connecting rod 53 is rotatably installed on the second locking seat 40, and a first avoidance hole 31 is provided in the first locking seat 30.

[0156] As Fig.11 、 Fig. 22As shown, when the second body 20 is in the open state, the connecting rod 53 can be rotated to a locking angle under the action of an external force so that the first locking block 51 and the avoidance hole 31 are at least partially offset, so that the vertical movement trajectory of the first locking block 51 is blocked by the first locking seat 30, and the first locking block 51 cannot pass through the avoidance hole 31 when moving upward.

[0157] like Fig.18 As shown, when the second body 20 is in the open state, the connecting rod 53 can be rotated to an unlocking angle under the action of external force to align the first locking block 51 with the avoidance hole 31, so that the vertical movement trajectory of the first locking block 51 is not blocked by the first locking seat 30, and the first locking block 51 can pass through the avoidance hole 31 and disengage from the first locking seat 30 when moving upward.

[0158] Optionally, the avoidance hole 31 is a vertical strip hole, the first locking block 51 is a strip structure, and when the connecting rod 53 drives the first locking block 51 to rotate to a horizontal state, as shown in FIG. Fig.11 , Fig. 22 As shown, the first locking block 51 moves upward and is blocked by the first locking seat 30 and cannot escape from the avoidance hole 31; when the connecting rod 53 drives the first locking block 51 to rotate to the vertical state, as shown in FIG. Fig.18 As shown, the first locking block 51 can escape from the avoidance hole 31 by moving upward.

[0159] Please refer to 8. Fig. 9 When the locking mechanism 50 configures the connecting rod 53 to have a locking angle and an unlocking angle, a positioning structure is provided between the connecting rod 53 and the locking seat to facilitate the user to perceive the angle state of the connecting rod 53.

[0160] Optionally, the second locking block 52 is provided with a second rod mounting hole 41, and the hole wall of the second rod mounting hole 41 is arranged with a first hole limiting step 411 and a second hole limiting step 412 at intervals around the hole center line, and the outer wall of the connecting rod 53 is arranged with a first rod limiting step 531 and a second rod limiting step 532 at intervals around the rod center line; when the connecting rod 53 rotates to the locking angle, the first rod limiting step 531 abuts against the first hole limiting step 411; when the connecting rod 53 rotates to the unlocking angle, the second rod limiting step 532 abuts against the second hole limiting step 412. By providing two sets of limiting steps on the hole wall of the second locking seat 40 and the outer wall of the connecting rod 53, it is possible to provide feedback and positioning of the connecting rod 53 when it rotates to the locking angle and the unlocking angle, which is more convenient and quick for the user to perform unlocking or locking operations.

[0161] It is understandable that a limiting step is provided on the hole wall of the second rod mounting hole 41 of the second locking block 52, and the connecting rod 53 is not required to limit the cooperation with the avoiding hole 31 of the first locking block 51, and the avoiding function of the avoiding hole 31 of the first locking block 51 for the first locking block 51 is not affected.

[0162] Of course, in other embodiments, a rotation angle limiting and positioning structure of the connecting rod 53 may be provided at other positions such as the top or bottom of the second locking seat 40, the top or bottom of the first locking seat 30, the first body 10, the second body 20, etc. Alternatively, a structure for limiting and positioning the angle of the connecting rod 53 may not be provided.

[0163] Please refer to Figure 7 , Figure 8 , Figure 5 , Fig.11 The locking mechanism 50 also includes a handle 55 and a connecting shaft 54; the second locking block 52 is a cam, and the second locking block 52 is rotatably connected to the first end of the connecting rod 53 through the connecting shaft 54, and the handle 55 is connected to the cam; the cam can rotate around the connecting shaft 54 ​​to increase or decrease the distance between the convex surface of the cam and the first locking block 51. Fig.11 The distance between the middle cam convex surface and the first locking block 51 in the z direction is less than Fig.18 The distance between the middle cam convex surface and the first locking block 51 in the z direction, therefore, Fig.11 In the embodiment, the locking mechanism 50 can clamp and lock the two locking blocks from the upper and lower sides.

[0164] Optionally, when the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the convex surface of the cam abuts against the second locking block.

[0165] Optionally, the connecting shaft 54 ​​between the cam and the connecting rod 53 is eccentrically set so that the distance between the connecting shaft 54 ​​and the convex surface of the cam changes, so that when the operating handle 55 rotates the cam, the distance between the cam of the cam and the first locking block 51 can change, thereby clamping or loosening the first locking seat 30 and the second locking seat 40 from both sides.

[0166] Optionally, refer to Figure 7 The second locking block 52 is a cam, which includes two spaced wheel blocks 5201, which are connected by a connecting block 5202, and a handle 55 is connected to the connecting block 5202. The end of the connecting rod 53 is inserted between the two wheel blocks 5201, and the connecting shaft 54 ​​passes through the two wheel blocks 5201 and the end of the connecting rod 53 to achieve a rotatable connection between the cam and the connecting shaft 54. The convex surface of the cam is formed on the outer wall of the wheel block 5201.

[0167] Alternatively, if Figure 6 As shown in the locking mechanism 50 on the left side, when the connecting rod 53 of the locking mechanism 50 is at the locking angle, the handle 55 extends in the front-to-back direction. Figure 6 As shown in the locking mechanism 50 on the right side, when the connecting rod 53 of the locking mechanism 50 is at the unlocking angle, the handle 55 extends in the left-right direction.

[0168] Optionally, the first locking block 51 is provided with a first rod mounting hole 511, and the connecting rod 53 passes through the first rod mounting hole 511. A fixing piece 57 is provided at one end of the first locking block 51 away from the second locking block 52, and the end of the connecting rod 53 is connected to the fixing piece 57, and the fixing piece 57 limits the connecting rod 53 from being separated from the second locking block 52; the first rod mounting hole 511 is a flat hole; the inner wall of the first rod mounting hole 511 is provided with a hole wall plane, and the outer wall of the connecting rod 53 is provided with a rod orientation plane 533, and the rod positioning plane is abutted against the hole wall plane to realize the torque transmission between the connecting rod 53 and the first locking block 51, so that when the handle 55 is rotated, the second locking block 52, the connecting rod 53, and the first locking block 51 are driven to rotate as a whole to adjust the angle between the connecting rod 53 and the second locking block 52.

[0169] Please continue to refer to Figure 7 , Fig.11 When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the convex surface of the cam abuts against the second locking block, the first body 10 is located on the front side of the second body 20, and the handle 55 extends forward from the end close to the cam to the end away from the cam. In this way, the handle 55 can be avoided from occupying the space above the second body 20. When the second body 20 is a pedal, the user needs to perform various movements on the pedal. When the locking mechanism 50 is locked, the handle 55 is moved away from the space above the pedal to avoid hindering the user's movement.

[0170] Optionally, a limit protrusion 56 is provided on the convex surface of the cam. When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the limit protrusion 56 abuts against the second locking block, and the handle 55 tilts, thereby preventing the handle 55 from approaching other structures downward, and keeping a certain space reserved under the handle 55, so that the user can hold the handle 55 when unlocking.

[0171] In other embodiments, when the locking mechanism 50 is in the locked state, the handle 55 may also extend backward.

[0172] In other embodiments, the locking mechanism 50 may also not include a cam, and the first locking block 51 is located on the lower side, the second locking block 52 is located on the upper side, one end of the connecting rod 53 is connected to the first locking block 51, and the other end of the connecting rod 53 is threadedly connected to the second locking block 52. The second locking block 52 is rotated to increase or decrease the vertical distance between the two locking blocks to clamp or loosen the two locking seats to achieve locking or unlocking.

[0173] Take a home fitness training device with a bird flying training function as an example. The training device has a frame at the front end and a pedal at the rear end. The pedal is designed to be foldable and can be folded when not in use to save space. The locking and unlocking of the pedal can be achieved through the design of the locking mechanism 50. However, in the related art, there are the following problems: First, for training devices with two rotatable bodies, it is difficult to simultaneously meet the two requirements of firm and reliable locking and convenient unlocking. Second, after the second body 20 (such as the pedal) is rotated to the folded state, it is difficult to move the entire device, and the operation is difficult. That is, the training device in the related art has problems such as poor locking after the second body 20 is opened and difficulty in moving the device after the second body 20 is folded.

[0174] Some embodiments of the training device of the present application can achieve the following effects:

[0175] First, by setting the interval between the locking position between the machine bodies and the hinged position between the machine bodies to extend the locking force arm, the locking effect is made more firm and reliable.

[0176] Second, the locking seats of the two bodies are arranged one above the other, so that the contact surface between the locking seats is larger during locking, and the locking force can be applied from the vertical direction through the locking mechanism 50, so that the locking is more firm and reliable.

[0177] Third, the locking mechanism 50 is designed with two locking blocks to clamp the locking seats of the two bodies from the upper and lower sides, making the locking more firm and reliable.

[0178] Fourthly, one of the locking blocks in the locking mechanism 50 is designed as a cam. By holding the handle 55 and rotating the cam, the locking and separation between the two locking seats can be easily achieved, and the operation is convenient.

[0179] Fifth, a avoidance hole 31 is arranged on the first locking seat 30 in the locking mechanism 50, so that the first locking block 51 can pass through the avoidance hole 31 and detach from the first locking seat 30 when the second body 20 is rotated and folded. In the case of no need to disassemble the locking mechanism 50 as a whole, the second body 20 can drive the locking mechanism 50 to detach from the first body 10.

[0180] Sixth, a first rear support member 71 is provided at the rear end of the first body 10, and the first rear support member 71 is a roller. After the locking mechanism 50 is unlocked and the second body 20 is flipped upward and folded off the ground, the roller at the rear end of the first body 10 can contact the ground, making it convenient to push the entire training equipment.

[0181] Seventh, when the second body 20 is opened and the locking mechanism 50 is locked, the locking of the locking mechanism 50 also serves to slightly lift the first rear support member 71 of the first body 10, so that the front and rear ends of the entire training device can touch the ground as much as possible, and the first rear support member 71 is off the ground, making the entire training device more stable during training.

[0182] Eighth, when the first front support member 72 is provided at the front end of the first body 10 and the first rear support member 71 is provided at the rear end, and both the first front support member 72 and the first rear support member 71 are rollers, when the second body 20 is folded, the front and rear end rollers of the first body 10 can touch the ground at the same time, which saves effort in pushing the entire training equipment and facilitates moving the equipment.
