DETAILED DESCRIPTION

[0056] 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.

[0057] 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.

[0058] 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.

[0059] In the related art, two components in many devices are configured to be able to move relative to each other, and when the device is in use, the two components need to be kept in a certain matching state.

[0060] Taking training equipment as an example, training equipment is a device used to train certain parts of the body, with functions such as enhancing physical ability, improving physical function, and promoting rehabilitation. In related technologies, some training equipment includes multiple bodies, and adjacent bodies are rotatably connected. When the body is flipped open, the equipment can be used for training. When the body is flipped and folded, the equipment footprint is reduced for easy storage, or the two bodies can be flipped to different angles to adjust the training mode of the training device. When the user uses the training equipment, if there is relative rotation between two adjacent bodies, it will affect the normal use of the equipment.

[0061] However, the inventors have found that although a locking mechanism is provided between the two bodies to have a certain locking function for the relative movement of the two bodies, these locking mechanisms have problems such as poor locking effect or troublesome unlocking operation after locking.

[0062] Based on this, please refer to Figures 1 to 16 The present application provides a locking assembly. For two rotationally connected components or two slidingly connected components, a locking assembly can be set between the components to lock the two components in a certain state through the locking assembly, and the two components can be kept in a certain state through the locking assembly.

[0063] The locking assembly can be applied to training equipment to lock two rotationally connected bodies. The locking assembly can also be applied to some other equipment, such as a smart interactive tablet.

[0064] The present application also provides a training device, which includes the aforementioned locking assembly, the two bodies are rotatably connected, and the two locking seats are respectively installed on the two bodies. The two bodies can be locked through the locking mechanism 50 to keep the two bodies in the current matching state.

[0065] For example, in the training device, the second body 20 can rotate relative to the first body 10, so that the second body 20 is rotated to an open state for use, or rotated to a folded state for storage. The locking assembly can be configured to lock the second body 20 in an open state, or can be configured to lock the second body 20 in a folded state.

[0066] The training device of the present application may be a strength training device, an aerobic training device, a balance training device, a rehabilitation training device or a comprehensive training device. For example, the training device is a strength training device, and the training device has a stand 12 and a pedal, and the pedal can rotate relative to the stand 12. For another example, the training device is a treadmill, and the treadmill has a main unit with handles and a running platform, and the running platform can rotate relative to the main unit.

[0067] The locking assembly and training equipment of the present application can not only lock the two locking seats, but also lock from both sides of the two locking seats through two locking blocks, so the locking effect is better and the locking strength is higher.

[0068] Furthermore, on the basis of locking the two locking blocks from both sides, when the positions of the two locking seats need to be adjusted, the entire locking mechanism 50 is moved or rotated, and the connecting rod 53 is adjusted to the unlocking position or unlocking angle, so that the first locking block 51 can be separated from the first locking seat 30 under the action of external force. At this time, the two locking seats can be separated from each other under the action of external force. In other words, when the user needs to adjust the relative position between the two locking seats and the two bodies, there is no need to disassemble the two locking blocks twice from both sides. The unlocking operation is convenient and fast, and the user experience is good.

[0069] The locking assembly and the training device are described in detail below by taking the application of the locking assembly to the training device as an example.

[0070] In order to easily understand the positional relationship between the components inside the training device, the y direction indicates the front and back direction of the training device, the x direction indicates the left and right direction of the training device, and the z direction indicates the up and 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, back, left, right, up and 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, back, left, right, up and down directions of the training device are consistent with the front, back, left, right, up and down directions of the user.

[0071] Please continue to refer to Figures 1 to 16 The training device includes a first body 10, a second body 20 and a locking assembly.

[0072] The second body 20 is rotatably connected to the first body 10. The locking assembly includes a first locking seat 30, a second locking seat 40 and a locking mechanism 50. The first locking seat 30 is disposed on the first body 10, the second locking seat 40 is disposed on the second body 20, and the locking mechanism 50 is used to lock and unlock the first locking seat 30 and the second locking seat 40.

[0073] The second body 20 has an open state and a folded state. Figures 3 to 7 , Fig.15 The second housing 20 is in an open state. Fig.16The second body 20 is in a folded state. When the user needs to use the training device, the second body 20 is adjusted to the open state, and the user can train on the second body 20; when the user does not use the training device, the second body 20 is adjusted to the folded state. Exemplarily, when the second body 20 is in the open state, the second body 20 is horizontal, and the second body 20 can be placed on the ground; when the second body 20 is in the folded state, the second body 20 is vertical, which can reduce the space occupied by the second body 20.

[0074] The second locking seat 40 has a mating state and a disengaging state. Figures 3 to 7 , Fig.15 The second locking seat 40 is in a mating state. Fig.16 The second locking seat 40 is in a separated state. When the second locking seat 40 is in a matched state, it is close to the first locking seat 30, which facilitates the locking mechanism 50 to lock the two locking seats. When the second locking seat 40 is in a separated state, it is far away from the first locking seat 30, and the locking mechanism 50 cannot lock the two locking seats. Exemplarily, when the second body 20 is in an open state, the second locking seat 40 is in a matched state. At this time, the two locking seats are close to each other, and the two locking seats can be locked by the two locking blocks of the locking mechanism 50 to limit the relative movement of the two locking seats, thereby limiting the relative rotation of the two bodies, thereby keeping the second body 20 in an open state. After the locking mechanism 50 is unlocked, the second body 20 can be rotated to a folded state by an external force. At this time, the second locking seat 40 is in a separated state away from the first locking seat 30.

[0075] Please continue to refer to Figure 1 , Figure 2 , Figure 6 , Figure 7 , Fig. 9 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. The locking mechanism 50 has a locked state and an unlocked state. The connecting rod 53 has a locking angle (such as Figure 5 , Figure 6 as shown) and unlocking angle (as shown Figure 3 , Figure 7 As shown), alternatively, the connecting rod 53 has a locked position or an unlocked position.

[0076] For ease of understanding, different states of the locking assembly are described below.

[0077] like Figure 5 , Figure 6As shown, when the second locking seat 40 is in a mating state close to the first locking seat 30 and the locking mechanism 50 is in a locking state, the connecting rod 53 is in a locking angle or a locking position, and 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. The first locking block 51 and the second locking block 52 lock and limit the two locking seats from both sides to limit the relative movement of the first locking seat 30 and the second locking seat 40, thereby limiting the relative rotation of the first body 10 and the second body 20 in the training equipment.

[0078] Among them, when the second locking seat 40 is in a mating state close to the first locking seat 30 and the locking mechanism 50 is in a locked state, if the second locking seat 40 needs to be adjusted from the mating state to the separated state, at least the connecting rod 53 must be adjusted from the locking angle to the unlocking angle, or the connecting rod 53 must be adjusted from the locking position to the unlocking position, so that the locking mechanism 50 can be adjusted from the locked state to the unlocked state.

[0079] like Figure 3 , Figure 7 As shown, when the locking mechanism 50 is in the unlocked state, the connecting rod 53 is in the unlocked angle or unlocked position, the first locking block 51 can be separated from the first locking seat 30 under the action of force, and the second locking seat 40 can move in the direction away from the first locking seat 30 under the action of force, so that the second locking seat 40 can be adjusted from the engaged state to the separated state under the action of force.

[0080] It is understandable that when the first locking block 51 is disengaged from the first locking seat 30, the locking mechanism 50 can be disengaged from the first locking seat 30; wherein, the first locking block 51 being disengaged from the first locking seat 30 means that the first locking block 51 leaves the space on the side of the first locking seat 30 away from the second locking seat 40.

[0081] Two unlocking methods are provided below, in which the locking mechanism 50 is unlocked, the second locking seat 40 is away from the first locking seat 30 , and the second body 20 rotates relative to the first body 10 .

[0082] Unlock method 1:

[0083] The locking mechanism 50 is movably mounted on the second locking seat 40 and movably connected. Optionally, the connecting rod 53 is rotatably connected or slidably connected to the second locking seat 40.

[0084] When the second locking seat 40 is in a mating state and the locking mechanism 50 is in an unlocking state, the second locking seat 40 can move in a direction away from the first locking seat 30 under the action of force, and the first locking block 51 (51) in the locking mechanism 50 can be driven by the second locking seat 40 to separate from the first locking seat 30, so that the second locking seat 40 can be adjusted to a separated state.

[0085] On this basis, one way to rotate the second body 20 from an open state to a folded state is: operate the entire locking mechanism 50, adjust the connecting rod 53 to an unlocking angle or an unlocking position, wherein the connecting rod 53 drives the first locking block 51 to rotate or move; then, the user can rotate the second body 20, the second body 20 drives the second locking seat 40 away from the first locking seat 30, and the second locking seat 40 drives the locking mechanism 50 away from the first locking seat 30, until the first locking block 51 of the locking mechanism 50 is separated from the first locking seat 30.

[0086] Unlock method 2:

[0087] The locking mechanism 50 can also be configured to be detachable from the second locking seat 40 , that is, when the connecting rod 53 is at an unlocking angle or unlocking position, the first locking block 51 can be detached from the first locking seat 30 and the second locking seat 40 under the action of an external force.

[0088] On this basis, another way to rotate the second body 20 from the open state to the folded state is: operate the entire locking mechanism 50, adjust the connecting rod 53 to the unlocking angle or unlocking position, wherein the connecting rod 53 will drive the first locking block 51 to rotate or move; then, the user pulls the locking mechanism 50 from one side to allow the first locking block 51 to disengage from the first locking seat 30 and the second locking seat 40 in turn, thereby allowing the locking mechanism 50 to completely disengage from the first locking seat 30 and the second locking seat 40. At this time, the second locking seat 40 and the first locking seat 30 are not restricted by the locking block, and the user can rotate the second body 20 to move the second locking seat 40 away from the first locking seat 30 and the second body 20 away from the first body 10.

[0089] The locking assembly of the present application has multiple advantages, including high locking strength and simple and convenient unlocking operation. The following is a detailed analysis:

[0090] First, in the locking assembly, two locking blocks are locked from both sides of the two locking seats. Compared with the method of locking only one side by a single locking block, this solution can limit the rotation tendency of the two locking seats, thereby limiting the rotation tendency of the two bodies. When applied to training equipment, after the locking mechanism 50 is locked, the rotation of the two bodies can be restricted. And by locking on both sides, the effect of restricting the rotation of the body is stronger.

[0091] Second, in the locking assembly, the first locking block 51 blocks the side of the first locking seat 30 away from the second locking seat 40, and the second locking block 52 blocks the side of the second locking seat 40 away from the first locking seat 30. The two locking blocks can apply locking force from a direction perpendicular or basically perpendicular to the locking seats. When the two locking seats have a relative rotation tendency, the contact area between the locking blocks and the locking seats is large, and the locking force can be basically perpendicular to the line connecting the locking point and the hinge point between the two bodies. The locking force has high locking efficiency and high locking strength.

[0092] Third, based on the solution of locking the lock blocks from both sides, the unlocking operation of the locking mechanism 50 of the present application does not need to unlock the two lock blocks from both sides respectively, which requires less operating space and is applicable to more scenarios. Even if it is inconvenient for the user to operate the first lock block 51 due to reasons such as limited operating space, it is convenient to operate the locking mechanism 50 from the second lock block 52 side to perform the unlocking operation.

[0093] In the present application, the connecting rod 53 of the locking mechanism 50 is configured to be rotatable or movable on the first locking seat 30. By adjusting the angle or position of the connecting rod 53, the first locking block 51 can be in a state where it can interfere with the first locking seat 30 to limit the movement of the first locking seat 30, or can be detached from the first locking seat 30 when the first locking seat 30 is in a space away from the second locking seat 40.

[0094] In this way, when the locking assembly is applied to training equipment, when the first locking block 51 is located in a very small space, for example, the first locking block 51 is located below the two locking seats and very close to the ground, although the user cannot and will not be able to reach the narrow space where the first locking block 51 is located, the user can directly perform the unlocking operation on one side of the second locking block 52, adjust the connecting rod 53 to the unlocking position or unlocking angle, and separate the locking mechanism 50 from the first locking seat 30 by pulling out the locking mechanism 50, thereby unlocking the two locking seats, thereby facilitating the separation of the two locking seats and adjusting the relative angle or position of the second body 20 and the first body 10.

[0095] It is understandable that if the locking mechanism 50 is configured as follows: the connecting rod 53 passes through the first locking seat 30 and the second locking seat 40, and the nuts are locked at both ends of the connecting rod 53 to lock the two locking seats through the nuts on both sides; then when unlocking, the locking nuts on both sides need to be removed from both sides, which may cause the problem of slow unlocking efficiency. When the locking mechanism 50 of the present application is unlocked, the first locking block 51 does not need to be operated from the side of the first locking block 51, which has the advantage of convenient and fast unlocking operation.

[0096] Fourth, when the locking mechanism 50 is configured to be movably installed on the second locking seat 40, when performing the unlocking operation, the locking mechanism 50 does not need to be removed from the second locking seat 40. The locking mechanism 50 can be separated from the first locking seat 30 as the second locking seat 40 moves, and the operation is convenient and quick.

[0097] In one embodiment, in the training equipment, when the first body 10 is arranged on the front side of the second body 20, the second body 20 is rotatably connected to the first body 10 through the rotating shaft 60, and the rotating shaft 60 extends in the left and right direction, when the locking mechanism 50 is in the locked state, the second locking block 52, the second locking seat 40, the first locking seat 30, and the first locking block 51 are distributed in the up and down directions. In this way, when the training force acts on the second body 20 (for example, the forward training force acts on the second body 20), the second body 20 has a tendency to rotate around the rotating shaft 60. At this time, the second locking seat 40 has a tendency to rotate forward and upward. The locking force can be applied in the up and down directions through the first locking block 51 and the second locking block 52, and the locking strength of the two locking seats is high, thereby effectively limiting the rotation of the second body 20 around the rotating shaft 60. It is understandable that for the locking method of "arranging an insert block on the second body 20, arranging a slot on the first body 10, and inserting the insert block forward into the slot", when the second body 20 has a tendency to rotate, the insert block is easy to fall out of the slot. In this embodiment, since the two locking blocks are located on the upper and lower sides of the two locking seats, the area of ​​the limiting surface between the locking blocks and the locking seats is large, the locking blocks are not easy to fall out of the locking seats, and the locking reliability is high. The following continues to explain the locking mechanism 50 including the first locking block 51 and the second locking block 52 as an example. The locking mechanism 50 also includes a connecting rod 53, and the two ends of the connecting rod 53 are respectively connected to the first locking block 51 and the second locking block 52.

[0098] 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.

[0099] Locking mechanism 50 setting method 1:

[0100] 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 .

[0101] 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.

[0102] The second setting method of the locking mechanism 50:

[0103] 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 .

[0104] 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.

[0105] The third setting method of the locking mechanism 50:

[0106] 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 .

[0107] 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.

[0108] Locking mechanism 50 arrangement mode 4:

[0109] 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 .

[0110] 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 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.

[0111] In the third and fourth settings of the locking mechanism 50, a first locking hole can be set in the first locking block 51, and a second locking hole can be set in the second locking block 52. 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 connected to the large hole portion. In this way, when the second body 20 needs to be kept in an open state, the connecting rod 53 is translated to the two small hole portions. At this time, the two locking blocks cannot pass through the two lock holes. When the second body 20 needs to be flipped upward and forward for storage, the connecting rod 53 is translated to the two large holes, so that when the user flips the second body 20, the locking block can pass through the large hole portion and disengage from the locking seat.

[0112] In addition to the first to fourth ways of arranging the locking mechanism 50 described above, in other embodiments, the first lock block 51, the connecting rod 53, and the second lock block 52 of the locking mechanism 50 can also be structures after folding a structure similar to the "凵" character by 90 degrees. When it is necessary to lock 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 up the second body 20, the locking mechanism 50 is then pulled out from the locking seat laterally. Or, in other embodiments, when it is necessary to turn up the second body 20, the locking mechanism 50 can be disassembled by loosening the screws, so that the two lock blocks are removed from both sides of the two locking seats, and the locking mechanism 50 is adjusted to the unlocked state.

[0113] Please refer to Figures 1 to 5 、 Fig.10 As shown in FIGS. , the locking mechanism 50 further includes a handle 55 and a connecting shaft 54; the second lock block 52 is a cam, and the second lock 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, so that the distance between the convex surface of the cam and the first lock block 51 increases or decreases. During the process that the distance between the convex surface of the cam and the first lock block 51 decreases, the first locking seat 30 and the second locking seat 40 can be continuously locked.

[0114] Optionally, the connecting shaft 54 between the cam and the connecting rod 53 is eccentrically arranged, so that the distance from the connecting shaft 54 to the convex surface of the cam changes. Thus, when the handle 55 is operated to rotate the cam, the distance between the cam of the cam and the first lock block 51 can be changed, so as to clamp or loosen the first locking seat 30 and the second locking seat 40 from both sides. Among them, as shown in FIGS. , the cam of the second lock block 52 has a convex surface. In the first region of the convex surface, the distance between the convex surface and the connecting shaft 54 is R1, and in the second region of the convex surface, the distance between the convex surface and the connecting shaft 54 is R2, and R2 is greater than R1. By the different distances between the convex surface of the cam and the connecting shaft 54, the distance between the cam and the first lock block 51 is adjusted when the cam rotates. Fig.10 As shown in FIGS. , the cam of the second lock block 52 has a convex surface. In the first region of the convex surface, the distance between the convex surface and the connecting shaft 54 is R1, and in the second region of the convex surface, the distance between the convex surface and the connecting shaft 54 is R2, and R2 is greater than R1. By the different distances between the convex surface of the cam and the connecting shaft 54, the distance between the cam and the first lock block 51 is adjusted when the cam rotates.

[0115] 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 seat 40, and the first lock block 51 abuts against the first locking seat 30.

[0116] Optionally, as shown in FIGS. Figure 1The 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.

[0117] Optionally, when the connecting rod 53 of the locking mechanism 50 is at a locking angle, the handle 55 extends in the front-to-back direction. When the connecting rod 53 of the locking mechanism 50 is at an unlocking angle, the handle 55 extends in the left-to-right direction.

[0118] In one embodiment, based on the first arrangement of the locking mechanism 50, the training device is configured as follows: when the second body 20 is in the open state, the second locking seat 40 is located on the upper side of the first locking seat 30, the second locking block 52 is located on the upper side of the second locking seat 40, and the first locking block 51 is located on the lower side of the first locking seat 30. In addition, the connecting rod 53 is rotatably mounted on the second locking seat 40, and the first avoidance hole 31 is provided on the first locking seat 30.

[0119] like Figure 7 As shown, when the second body 20 is in an open state and the second locking seat 40 is in a mating state, the connecting rod 53 can be rotated to a locking angle under the action of an external force to drive the first locking block 51 to be at least partially offset from the avoidance hole 31, 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.

[0120] And, if Figure 6 As shown, when the second body 20 is in an open state and the second locking seat 40 is in a mating state, the connecting rod 53 can be rotated to an unlocking angle under the action of an external force to drive the first locking block 51 to align 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 to disengage from the first locking seat 30 when moving upward.

[0121] Among them, for the locking mechanism 50 in which the second locking block 52 is a cam and has a handle 55 connected to the cam, when it is necessary to release the two locking seats, the following two steps of unlocking operations are required: first, first move the handle 55 to increase the distance between the cam and the first locking block 51, so that the clearance between the first locking block 51 and the first locking seat 30 is matched, and the first locking block 51 has the freedom to rotate relative to the first locking seat 30; second, adjust the position or angle of the locking mechanism 50, adjust the connecting rod 53 to the unlocking position or unlocking angle, and facilitate the adjustment of the first locking block 51 to the position aligned with the avoidance hole 31. In this way, when locking is required, the first locking block 51 can be pressed against the first locking seat 30 to provide stable limiting; and when unlocking is required, the first locking block 51 can be moved relative to the first locking seat 30.

[0122] In one embodiment, the avoidance hole 31 is a non-circular hole, so that when the angle of the first locking block 51 is adjusted, the first locking block 51 can be adjusted so that it cannot pass through the avoidance hole 31 or can pass through the avoidance hole 31. Optionally, the avoidance hole 31 is a bar-shaped hole, the first locking block 51 is a bar-shaped structure, and the connecting rod 53 drives the first locking block 51 to rotate to a horizontal state. 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 a vertical state, the first locking block 51 moves upward and can escape from the avoidance hole 31.

[0123] 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.

[0124] Optionally, the second locking seat 40 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.

[0125] 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.

[0126] 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.

[0127] Please refer to Figure 1 , Figure 2 , Fig. 9 The first locking block 51 is provided with a first rod mounting hole 511, a fixing piece 57 is provided on a side of the first locking block 51 away from the second locking block 52, and an end of the connecting rod 53 away from the second locking block 52 passes through the first rod mounting hole 511 to be connected with the fixing piece 57. The hole wall of the first rod mounting hole 511 has a hole wall matching surface 5111, and the outer wall of the connecting rod 53 is provided with a rod wall matching surface 533. When the connecting rod 53 rotates around its center line under the action of an external force, the rod wall matching surface 533 abuts against the hole wall matching surface 5111, so that the rod wall matching surface 533 can apply a rotational force to the hole wall matching surface 5111, that is, the torque is transmitted to the first locking block 51 through the connecting rod 53.

[0128] In other words, 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, so as to adjust the angle between the connecting rod 53 and the second locking block 52 .

[0129] This assembly method of the connecting rod 53 and the first locking block 51 is convenient and quick to assemble, and does not require welding or gluing of the connecting rod 53 and the first locking block 51. The connecting rod 53 can transmit torque to the first locking block 51, and the angle of the first locking block 51 can be adjusted by adjusting the angle of the connecting rod 53, so that the first locking block 51 can be adjusted to pass through the avoidance hole 31 of the first locking seat 30 or cannot pass through the avoidance hole 31 of the first locking seat 30.

[0130] Optionally, the hole wall mating surface 5111 is a plane, and the rod wall mating surface 533 is also a plane. A plane has a good torque transmission effect. In other embodiments, the hole wall mating surface 5111 and the rod wall mating surface 533 can also be other special-shaped planes that can transmit torque.

[0131] In one embodiment, the first rod mounting hole 511 is a flat hole having two opposite flat surfaces and two opposite curved surfaces.

[0132] In other embodiments, the first rod mounting hole 511 may also be a round hole, and the connecting rod 53 is connected to the first locking block 51 through a thread. In order to transmit the torque of the connecting rod 53 to the first locking block 51, a pin is added to pass through the connecting rod 53 and the first locking block 51.

[0133] In one embodiment, please refer to Figure 1 , Fig.14 A guide surface 512 is provided on the side of the first locking block 51 facing away from the second locking block 52, the side of the guide surface 512 close to the second locking block 52 is the first side, the side of the guide surface 512 away from the second locking block 52 is the second side, and the guide surface 512 is inclined from the second side to the first side in a direction away from the center line of the connecting rod 53.

[0134] When the second body 20 is adjusted from the folded state to the opened state, the first locking block 51 passes through the avoidance hole 31 to reach the side of the first locking seat 30 away from the human locking seat. The setting of the guide surface 512 makes it easier for the first locking block 51 to pass through the avoidance hole 31, thereby reducing the positioning accuracy requirement.

[0135] In one embodiment, the cam has a convex surface, and a limiting protrusion 56 is provided on the convex surface of the cam; when the second locking seat 40 is in a mating state and the locking mechanism 50 is in a locking state, the limiting protrusion 56 abuts against the side of the second locking seat 40 away from the first locking seat 30, and a first angle is formed between the handle 55 and the second locking seat 40, and the first angle is greater than 0 degrees and less than 90 degrees.

[0136] When the second body 20 is in the open state and the locking mechanism 50 is in the locked state, the limiting protrusion 56 abuts against the second locking seat 40, and the handle 55 tilts, thereby preventing the handle 55 from approaching other structures downward, keeping a certain space reserved under the handle 55, so that the user can hold the handle 55 when unlocking.

[0137] In other embodiments, when the locking mechanism 50 is in the locked state, the handle 55 may also extend backward.

[0138] Optionally, the training device is a resistance training device.

[0139] like Fig.15 , Fig.16 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 are arranged on the support base 11. The second body 20 is a pedal, which is rotatably connected to the support base 11 through a rotating shaft 60. When the pedal is in the open state, a standing area is provided for the user, and the user can stand on the pedal during training. Among them, when the locking mechanism 50 is in the unlocked state, the pedal can be rotated to the open state in the direction away from the stand 12 under the action of an external force, or rotated to the folded state in the direction close to the stand 12.

[0140] like Fig.15As shown, when the second body 20 is in the open state and the locking mechanism 50 is in the locked state, if the stand 12 is subjected to a forward pulling force, the stand 12 has a tendency to flip backward, generating a torque M1, and the locking mechanism 50 locks the two locking seats through two locking blocks, which can provide a reverse resistance torque M2, achieving the effect of locking and resisting the rotation of the stand 12. During training, the equipment is stable.
