[0027] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with the drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the protection scope of the present invention.

[0028] Embodiment

[0029] Please refer to Figures 1 to 9 As shown, this embodiment provides a strength training bridge, including two module units 1; the two module units 1 are arranged along the length direction of the base 11 and are rotatably connected, and are used to jointly form an arched structure with a downwardly convex bottom surface by the bases 11 of the two module units 1. Among them, the arched structure has the instability of a seesaw, and balance training can be carried out thereon, or the difficulty of relevant training can be increased or targeted training can be carried out by controlling balance or creating imbalance during conventional training; the rotatably connected connection structure itself has a locking function or needs to additionally increase a locking function, and is used to keep the two module units 1 relatively fixed through the locking function after relative rotation, so as to realize the adjustment of the included angle of the two module units, and further adjust the training difficulty.

[0030] Of course, the above structure is only a preferred embodiment. The strength training bridge can also be designed with multiple module units 1 (more than two). The module unit 1 includes a base 11. Two adjacent module units 1 are arranged along the length direction of the base 11 and are fixedly connected and / or rotatably connected. Under the condition of ensuring the load-bearing strength, the module units can be reasonably divided and assembled together. Fixed connection means that it can be fixedly connected through a connecting piece (non-rotatable) or can also be an integral structure. Among the multiple module units that make up the same strength training bridge, they can all be in a fixed connection mode, or all be in a rotatable connection mode, or a mixed use of fixed connection mode and rotatable connection mode can also be adopted.

[0031] Referring again to Figure 6 and Figure 7 As shown, grip handles 12 are provided on the bases 11 of both module units 1. The design of the grip handles adds contact parts for the hands to the strength training bridge and provides more training functions. Of course, in addition to the grip handles 12, the two ends of the strength training bridge itself can also be used as the using parts (supporting hands, feet, etc.) of the user. Of course, when multiple module units (more than two) are adopted, grip handles 12 are respectively provided on the bases 11 of at least two of the multiple module units 1 to expand the training functions of the strength training bridge.

[0032] Referring again to Figure 5 As shown, the module unit 1 with the grip handle 12 is detachably connected to its adjacent module unit 1 for using the module unit with the grip handle 12 as a push-up fitness device after being disassembled. The module unit with the grip handle 12 can be removed for separate use. It should be noted here that on the basis of the above arched structure, the connection structure 2 is correspondingly designed at the bottommost end of the arched structure. The bases of the two module units 1 in this embodiment are mirror-designed, and the bottom surface of the base also becomes an arc that forms half of the arch. In this way, when the two module units 1 are separated and used as push-up fitness devices, the arc-shaped curved surface design of their bottom surfaces also has the characteristic of instability, which can also increase the difficulty of push-ups and improve the training effect.

[0033] Referring again to Figure 1 、 Figure 3 and Figure 9 As shown, a pull rope 3 is also connected between the grip handles 12 of the two module units 1; the pull rope 3 is used to control the distance between the two grip handles 12, and thus control the included angle between the two module units 1. The arched structures of the bases of the two module units will cause the curvature at the bottom end of the arched structure to decrease or increase as the included angle increases or decreases; when the curvature decreases, the balance is relatively easier to control, and the difficulty of related actions is relatively reduced; when the curvature increases, the balance is relatively difficult to control, and the difficulty of related actions is relatively increased. Figure 9That is, the specific state of the angle change is given; the use of the pull rope 3 is equivalent to adding a locking function to the rotatable connection structure; when this product is actually used, the angle can be appropriately adjusted through the pull rope according to actual needs to achieve the best training effect; in addition, the combination of the pull rope 3 and the rotatable connection structure 2 can also be replaced by other structures. This requires consideration of the strength of the connection. Under the condition of meeting the strength requirements, other structures can also be used, such as connection through splines and keyways (equivalent to the rotatable connection structure itself having a locking function).

[0034] Refer again Figure 3 and Figure 4 As shown, the connection structure 2 includes a shaft rod 21 and a shaft sleeve 22 ; the shaft rod 21 and the shaft sleeve 22 are arranged on their respective module units 1 ; an opening 23 is provided on the shaft sleeve 22 for facilitating the disassembly and assembly of the shaft sleeve 22 on the shaft rod 21 . Specifically, the cross-section of the shaft 21 perpendicular to its length direction (axial direction) is set to be a rectangular shape, which has a pair of parallel straight sides and a pair of arc-shaped segments located on the same circle; and the minimum size of the opening only needs to be slightly larger than the vertical distance of the pair of parallel straight sides, so that the shaft 21 can enter the sleeve 22 through the opening 23. At the same time, the shaft 21 cooperates with the inner wall of the sleeve 22 through the surface corresponding to the arc-shaped segment, thereby ensuring the function of the shaft 21 to rotate in the sleeve 22; in addition, the inner wall of the sleeve 22 is provided with shallow grooves distributed along its axial direction; and the shaft 21 is provided with a semicircular ridge along the axial direction on the surface corresponding to the arc-shaped segment, which cooperates with the shallow groove to increase the rotational resistance between the shaft 21 and the sleeve 22 and reduce the friction between the sleeve 22 and the shaft 21 slides, after the length of the pull rope is adjusted and the angle between the two module units is fixed, the design of the shallow groove and the ridge can improve the stability of the sleeve 22 and the shaft rod 21; in addition, the surface corresponding to the straight edge of the shaft rod 21 is generally horizontal, and the opening is opened upward or downward. Such a design allows the sleeve 22 to be sleeved on the shaft rod 21 through the opening at the angle where the two module units are not in use, and when the two module units are at the commonly used angles, the sleeve 22 and the shaft rod 21 are in a rotationally matched state, and the shaft rod 21 does not fall out of the opening of the sleeve 22; of course, the connection structure can also adopt other methods, as long as it can ensure that the angle between the two module units is adjustable. The above-mentioned connection method adds the function of quick disassembly and assembly on the basis of rotation.

[0035] In the strength training bridge of this embodiment, the gripping handle 12 is fixed to the base 11 by a support structure. The support structure can be in various forms, as long as the gripping handle is fixed to the base 11. The support structure, gripping handle, and base can be an integrated structure or an assembled structure.

[0036] Refer again Figures 5 to 8As shown, both the support structure and the base are configured as frame structures; the frame structure has at least one rod portion that can be grasped. Specifically, the frame structure of the base is an arched frame, which has parallel straight edges on the left and right sides and arc-shaped curved edges on the front and back sides (for the convenience of giving examples of corresponding structures and clear description, the length direction of the arch is defined as the left-right direction); multiple rod portions can be arranged inside the frame, and the multiple rod portions can be parallel to the two straight edges or not; on the one hand, it strengthens the stability of the base, and on the other hand, it provides a grasping function. The angles of the rod portions with respect to the length direction of the arch are diverse, which can provide multiple grasping angles. Of course, only the most basic rod portions for grasping can also be provided, and this can be designed according to actual needs; for the frame structure of the support structure, it has a first side 13 and a second side 14 that are respectively connected to the two ends of the corresponding front / rear curved edges of the base at the front / back ends of the grasping handle. The frame structure of the support structure also includes a rod portion 15 arranged at the front / back ends of the grasping handle near the middle position of the corresponding front / rear curved edges of the base; of course, multiple structures similar to the third side 15 can also be designed, so as to provide multiple rod portions that can be grasped on the front and back sides of the support structure, and at the same time, it also strengthens the stability of the support structure; on the basis of the above, specific reasonable designs can be made according to actual needs. For example, the positions where the two ends of the rod portion are connected and the formed grasping angles can be appropriately adjusted, as long as the structure of the module unit is stable, the force is reasonable, it has good load-bearing capacity, and its own weight is light.

[0037] Referring again to Figure 5 As shown, support surfaces 16 are respectively arranged at positions near the two ends of the frame structure in the length direction of the arched structure. When the user does a plank, the support surfaces are used to pad the user's forearms; pads 18 are also arranged on the support surfaces 16 to improve the anti-slip safety and comfort of the user. Specifically, in this embodiment, taking the module unit on the left as an example (the module unit on the right is a mirror structure of the module unit on the left in terms of structures other than the connection structure), the first side is defined as on the left, and the first side is arranged as a downwardly convex arc-shaped structure. An arc-shaped curved surface structure is formed between the two first sides, and the top surface of this curved surface structure is the support surface 16. The downwardly convex arc-shaped curved surface structure better meets the support requirements for the user's forearms when the user does a plank.

[0038] The strength training bridge of this embodiment has two states: integral use and separate use, and can be used for various trainings, specifically as follows:

[0039] Overall usage state:

[0040] A. When the strength training bridge is placed in a way that the convex part of the arched structure contacts the ground, the following trainings can be carried out:

[0041] A1. Unstable plank training: In the normal plank position, the user supports the forearms on the supporting surfaces at both ends of the strength training bridge. Due to the instability of the arched structure, the user needs to mobilize more muscle strength to maintain balance on the basis of maintaining the plank movement. Compared with the conventional plank, the strength training effect is better. In addition, the training difficulty can be controlled by adjusting the angle between the two module units to control the distance between the two arms and the curvature of the arched structure;

[0042] A2. Unstable push-up training: In the normal push-up position, the user supports or grips on the strength training bridge. Due to the instability of the arched structure, the user needs to mobilize more muscle strength to maintain balance on the basis of maintaining the push-up movement. Compared with the conventional push-up, the strength training effect is better; Specifically, the training difficulty can be controlled by the position where the user grips. For example, when gripping at both ends of the strength training bridge, conventional push-up training can be performed. When gripping on the gripping handles, narrow-arm push-up training can be performed. Of course, the training difficulty can also be controlled by adjusting the angle between the two module units to adjust the distance between the two hands and the curvature of the arched structure;

[0043] A3. High-low push-up training: This training increases the difficulty of creating imbalance compared to the push-up training in A2 and has a higher difficulty in controlling balance compared to A2. It can also specifically train the uneven left and right strength. In addition, in the high-low push-up training, when the hands grip both ends of the strength training bridge, in order to prevent the strength training bridge from pressing on the hands when deflecting, a support foot 17 is provided at the position of the arc-shaped curved edge of the frame structure of the base near the end opposite to the connection. This support foot can leave a distance between the straight edge at this end of the frame structure and the ground when deflecting to the maximum angle;

[0044] A4. Standing balance training: Standing on both ends of the strength training bridge, a seesaw-style balance training can be performed. It is not recommended to adjust the angle between the two module units too small during this process;

[0045] B. When the side of the arched structure of the strength training bridge contacts the ground, push-up training can be performed. At this time, through the angular design of the rod part on the side of the arched structure, when the user does push-ups, the wrist can be turned outward or inward (providing an inward function when one side of the strength training bridge faces up and an outward function when the other side faces up), which can change the muscle shape from the arm to the shoulder and thus change the exercise intensity for different muscle groups;

[0046] C. In addition, when the convex part of the arched structure is placed upward, corresponding push-up training can also be performed.

[0047] The strength training bridge in this implementation can be used on all sides, which is very convenient.

[0048] Separate usage state:

[0049] D. The two module units are disassembled and used as separate push-up fitness devices;

[0050] D1. The arc-shaped curved surface of the bottom plate of the two module units is in contact with the ground, which has a similar function to A2 above. On the basis of conventional push-up training, it can increase the difficulty of maintaining balance and the training intensity of wrist strength; in addition, the separate module units can provide a wider spacing compared to the overall state for wide-arm push-up training; in addition, the aforementioned support feet 17 can also prevent the base from deflecting excessively and causing wrist injuries;

[0051] D2. When the sides of the two module units are in contact with the ground, conventional push-up training can be carried out.

[0052] The strength training bridge of this embodiment forms a downwardly convex arched base. This arched structure has the instability of a seesaw, and balance training can be carried out on it, or in conventional training, by controlling balance or creating imbalance, the difficulty of relevant training can be increased or targeted training can be carried out to improve the exercise effect; two independent module units with gripping handles can be disassembled and used as push-up fitness devices. The arc-shaped design of the base of the module unit helps to enhance the exercise of arm strength; the design of the support structure and the frame structure of the base ensure the overall light weight. At the same time, the design of the rod part that can be gripped, on the one hand, improves the stability and load-bearing strength of the frame structure, and on the other hand, provides multiple grippable parts, and the angle of the rod part can be designed to give different gripping angles, changing the shape from the arm to the shoulder, and thus changing the exercise intensity of different muscle groups; the overall structure is simple, with rich functions and beautiful appearance, meeting the needs of users for targeted strength training, especially suitable for strength training and balance training of chest muscles, lumbar muscles, and arms.

[0053] The above embodiments should not limit the present invention in any way. All technical solutions obtained by means of equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
