[0039] As shown in the attached Figure 1 to the attached Figure 3As shown in the figure, an embodiment of the present utility model provides a multifunctional push-up board, which includes a bottom plate 10 and push-up handles 20. During training, the bottom plate 10 is placed on a plane as the load-bearing structure of the entire trainer. The push-up handles 20 are detachably connected to the bottom plate 10, and the trainer can cooperate with the push-up handles 20 on the bottom plate 10 to perform push-up exercises. The bottom plate 10 of this embodiment is a straight plate structure, which has a larger contact area with the plane, is placed more stably, and improves the stability and safety of the trainer during exercise.

[0040] The bottom plate 10 has a folding line 16 and can be folded relative to the folding line 16; several handle fixing holes 13 are provided on the bottom plate 10, and the push-up handles 20 are detachably connected to the handle fixing holes 13; the bottom of the bottom plate 10 has a concave structure 14, and a convex structure 15 corresponding to the handle fixing holes 13 is provided in the concave structure 14. A placement area 141 for accommodating the push-up handles 20 is provided in the concave structure 14, and a convex structure 15 is provided in the placement area 141. The push-up handle 20 has a hollow part 22, and the outer diameter of the convex structure 15 is less than or equal to the size of the hollow part 22 of the push-up handle 20, so that when the push-up handle 20 is placed in the placement area 141, the convex structure 15 passes through the hollow part 22.

[0041] The bottom plate 10 of this embodiment is a foldable structure. Specifically, the bottom plate 10 has a folding line 16, which divides the bottom plate 10 into a first bottom plate 11 and a second bottom plate 12. The first bottom plate 11 and the second bottom plate 12 can be folded relative to the folding line 16, and after folding, the bottoms of the first bottom plate 11 and the second bottom plate 12 are attached, so that the floor area of the folded bottom plate is smaller.

[0042] When the bottom plate is folded, the concave structure 14 forms a space for accommodating the push-up handles 20 and other accessories. Therefore, the depth of the concave structure 14 is greater than or equal to half of the push-up handle 20. Thus, when the bottoms of the first bottom plate 11 and the second bottom plate 12 are closed, the push-up handles 20 can be completely accommodated, and due to the cooperation of the placement area 141 and the convex structure 15, the push-up handles 20 will not shake between the first bottom plate 11 and the second bottom plate 12.

[0043] Specifically, the edge of the placement area 141 has a convex strip 142 that matches the shape of the push-up handle 20. The height of the convex strip 142 is less than the depth of the concave structure 14, which can not only limit the push-up handle 20 but also play an indicating role.

[0044] As shown in the attached Figure 2As shown in the figure, further, a receiving plate 143 corresponding to the holding part 21 of the push-up handle 20 is provided in the placement area 141. An arc-shaped groove 144 is provided on the receiving plate 143 for placing the holding part 21. When the first bottom plate 11 and the second bottom plate 12 are closed, the two receiving parts clamp the holding part 21 of the push-up handle 20, further fixing the push-up handle 20 and preventing it from shaking.

[0045] Further, as shown in the appendix Figure 2 As shown in the figure, the first bottom plate 11 and the second bottom plate 12 are connected by a rotating connecting member 30. Specifically, connecting parts 111 are provided at the opposite ends of the first bottom plate 11 and the second bottom plate 12. The connecting part 111 includes two spaced positioning plates 112, a positioning groove 113 located on the positioning plate 112, and a receiving groove 114 between the two positioning plates 112; four connecting parts 111 are provided on the first bottom plate 11, and four corresponding connecting parts 111 are also provided on the second bottom plate 12. A rotating connecting member 30 is respectively rotatably connected to the connecting parts 111 of the first bottom plate 11 and the second bottom plate 12. Specifically, for the connecting parts 111 at the relative positions on the first bottom plate 11 and the second bottom plate 12, the receiving grooves 114 thereof communicate with each other. The rotating columns 31 at both ends of the rotating connecting member 30 are respectively rotatably connected to the positioning grooves 113 of the positioning plates 112 on both sides of the receiving groove 114. The plate-like structure 32 of the rotating connecting member 30 is partially located in the receiving groove 114 of the first bottom plate 11, and the other part of the structure is located in the receiving groove 114 of the second bottom plate 12, so that the first bottom plate 11 and the second bottom plate 12 are connected and can be relatively folded. The width of the plate-like structure 32 of the rotating connecting part 111 is basically the same as the total thickness when the first bottom plate 11 and the second bottom plate 12 are attached to each other at the bottom, so that the folded first bottom plate 11 and the second bottom plate 12 are basically a cuboid.

[0046] As shown in the appendix Figure 2 As shown in the figure, the positioning groove 113 includes an arc-shaped groove 1131 and a straight opening 1132, and the diameter of the arc-shaped groove 1131 is larger than the width of the straight opening 1132. Correspondingly, rotating columns 31 are provided at both ends of the rotating connecting member 30, and the size is adapted to the arc surface of the positioning groove 113. After the rotating columns 31 are clamped into the arc-shaped groove 1131, restricted by the smaller-sized straight opening 1132, the rotating columns 31 are not easily disengaged from the positioning groove 113 and can rotate normally in the arc-shaped groove 1131.

[0047] In order to meet the requirements of different push-up movements for trainers of different body types, there are numerous handle fixing holes 13 on the bottom plate 10, and they are distributed in groups. Specifically, a number of handle fixing holes 13 on the first bottom plate 11 and the second bottom plate 12 are symmetrically arranged with respect to the folding line 16 as the axis of symmetry. The number of handle fixing holes 13 includes several groups of mounting positions perpendicular to the length direction of the bottom plate 10, at least one group of mounting positions parallel to the length direction of the bottom plate 10, and at least one group of mounting positions distributed in a triangular shape; the distance between the handle fixing holes 13 in each group of mounting positions is adapted to the distance of the positioning protrusions 23 of the push-up handle 20. In this embodiment, there are three groups of mounting positions perpendicular to the length direction of the bottom plate 10, and each mounting position includes two handle fixing holes 13 whose distances are adapted to the distance of the positioning protrusions 23 of the push-up handle 20; one group of mounting positions parallel to the length direction of the bottom plate 10, that is, two handle fixing holes 13 whose distances are adapted to the distance of the positioning protrusions 23 of the push-up handle 20 are arranged along the length direction of the bottom plate 10; one group of mounting positions distributed in a triangular shape, including three handle fixing holes 13, which are distributed in an equilateral triangle, and the side length is equal to the distance of the positioning protrusions 23 of the push-up handle 20. The handle fixing holes 13 in each group of mounting positions are marked with the same color, and the colors of the handle fixing holes 13 in different groups of mounting positions are different, so as to guide the trainer to insert the push-up handle 20 into the corresponding handle fixing holes 13.

[0048] Since when doing push-ups, the force of the trainer on the push-up handle 20 and the bottom plate 10 always remains downward, the handle fixing holes 13 can be round holes, and the corresponding positioning protrusions 23 of the push-up handle 20 can be cylinders. The cylinders are adapted to be inserted into the round holes, and generally, the push-up handle 20 has two positioning protrusions 23, which respectively correspond to two handle fixing holes 13. Therefore, after the push-up handle 20 is fixed on the bottom plate 10, it is not easy to shake, which is beneficial to maintaining the stability of the push-up handle 20 during training.

[0049] Of course, in other embodiments, the push-up handle 20 and the handle fixing holes 13 can also be magnetically attracted; or other conventional plug-in settings.

[0050] In this embodiment, the bottom surface of the convex structure 15 is flush with the bottom surface of the bottom plate 10, that is, when the bottom plate 10 is unfolded for use, the bottom surface of the convex structure 15 also contacts the plane. Therefore, as shown in the attached Figure 2 figure, the bottom surface of the convex structure 15 is provided with an anti-slip pad 151, which plays an anti-slip role to prevent the bottom plate 10 from sliding during training and has better stability. The anti-slip pad 151 is arranged on the convex structure 15, and the convex structure 15 corresponds to the handle fixing holes 13. The inner wall of the handle fixing holes 13 itself also needs to extend towards the bottom of the bottom plate 10. Therefore, the combination of the two simplifies the structure of the bottom plate 10, eliminates the need for an additional fixing structure, reduces the processing difficulty and material consumption, and saves costs. The anti-slip pad 151 can be a conventional setting, using anti-slip protrusions and anti-slip materials, such as rubber, etc.

[0051] In this embodiment, as shown in the appendix Figure 1 As shown, a timer 40 or a counter can be respectively embedded in the first bottom plate 11 and the second bottom plate 12. For example, a counter is embedded in the first bottom plate 11 and a timer 40 is embedded in the second bottom plate 12. The timer 40 and the counter are arranged close to the folding line 16 for the trainer to observe during exercise. Moreover, the timer 40 or the counter is detachably connected to the bottom plate, that is, clamping holes 115 are provided at corresponding positions of the first bottom plate 11 and the second bottom plate 12. The timer 40 or the counter can be placed in the clamping holes 115. When the timer 40 or the counter is not needed, the clamping holes 115 can be covered with a cover plate 41, which fully takes into account the production and manufacturing and the personalized needs of consumers.

[0052] In this embodiment, through grooves 116 are provided at the ends of the first bottom plate 11 and the second bottom plate 12 that are relatively far away from each other. When the first bottom plate 11 and the second bottom plate 12 are folded relative to each other, the two through grooves 116 are opposite and communicate with each other to form a carrying handle. The carrying handle and the rotating connecting piece 30 are respectively located at both ends of the folded bottom plate 10, so that a stable accommodating space is formed inside the folded bottom plate 10 to accommodate the push-up handle and it is not easy to fall out; the carrying handle facilitates the trainer to pick up or carry the folded trainer.

[0053] In order to further broaden the use of the multifunctional push-up board in this embodiment, two groups of tracks 18 are also provided on the bottom plate 10. The tracks 18 extend along the length direction of the bottom plate 10 and are parallel to each other; a sit-up board assembly is also included. The sit-up board assembly is detachably connected to the bottom plate 10 and can slide along the tracks 18; a number of handle fixing holes 13 are located between the two groups of tracks 18 to make full use of the space on the bottom plate 10. At the same time, the protruding structure 15 corresponding to the handle fixing holes 13 can also play a supporting role between the tracks 18 to further improve the stability of the bottom plate 10.

[0054] As shown in the appendix Figure 4 As shown, on the bottom plate 10 of this embodiment, each group of tracks 18 includes a sliding track 181 and two rolling tracks 182. The sliding track 181 is located between the two rolling tracks 182. Correspondingly, the sliding device 50 includes a sliding part 51 and a rolling part 52 at the bottom. The sliding part 51 cooperates with the sliding track 181 to slide. The sliding track 181 is a vertically through structure. The sliding part 51 passes through the sliding track 181 and a limiting block is provided at the bottom to cooperate with and be clamped to the bottom of the sliding track 181 to prevent the sliding device 50 from detaching from the sliding track 181; the rolling part 52 can be one of a roller, a bearing or a ball, and rolls in cooperation with the rolling track 182.

[0055] In this embodiment, the track 18 disposed on the bottom plate 10 will reduce the structural strength of the bottom plate 10. When the trainer applies force to the bottom plate 10 and the sliding device 50 thereon, the position corresponding to the track 18 is easily deformed, and the force effect is not good. Figure 6 As shown, the several reinforcing ribs 118 at the bottom of the base plate 10 of this embodiment correspond to the two rolling tracks 182, that is, on the first base plate 11 and the second base plate 12, several reinforcing ribs 118 are provided under the two rolling tracks 182 on each side, and the bottom surface of the reinforcing ribs 118 is flush with the bottom surface of the base plate 10. Therefore, the force of the trainee can be transmitted to the plane through the reinforcing ribs 118, providing support force for the sliding device 50 when sliding, preventing the base plate 10 and the track from deforming and affecting the sliding effect.

[0056] As attached Figure 4 As shown, the abdominal board assembly includes two groups of sliding devices 50, each sliding device 50 slides corresponding to a group of tracks 18. When the multifunctional push-up board is used for abdominal exercises, each group of sliding devices 50 corresponds to a hand or a leg of the trainee; each group of sliding devices 50 includes a support portion 54 and a handle 55, and the handle 55 is detachably connected to the support portion 54. When the trainer is used for abdominal exercises dominated by the legs, the handle 55 is not connected to the support portion 54; and when the trainer is used for abdominal exercises dominated by the hands, the handle 55 is connected to the handle mounting hole 545 and fixed to the support portion 54 for the trainee to hold.

[0057] As attached Figure 4 and attached Figure 5As shown, a separable connection component 53 is provided between the two sets of sliding devices 50. The connection component 53 includes an extension tube 531, a connecting rod 532, a spring 533, and a locking member 534. The extension tube 531 is located on the opposite surfaces of the two sliding devices 50. The two ends of the connecting rod 532 are inserted into the two extension tubes 531 to connect the two extension tubes 531. The spring 533 is located in one of the extension tubes 531, with one end abutted against one end of the connecting rod 532 and the other end abutted against the inner wall of the extension tube 531. Two locking grooves 535 arranged at intervals and a moving groove 536 communicating the two locking grooves 535 are provided on the side surface of this extension tube 531. The locking member 534 is fixed to one end of the connecting rod 532. The connecting rod 532 can rotate and move in the extension tube 531. The locking member 534 is a locking rod. When it is necessary to connect the two sliding devices 50, hold the locking rod and rotate the connecting rod 532 so that the locking rod moves from one locking groove 535 away from the other extension tube 531 to the moving groove 536. At this time, the spring 533 is in a compressed state, applying a thrust force to the connecting rod 532, causing the connecting rod 532 to move towards the other extension tube 531 and insert. At the same time, the locking rod moves in the moving groove 536. When the locking rod corresponds to the position of the locking groove 535 close to the other extension tube 531, hold the locking rod again and rotate the connecting rod 532 so that the locking rod snaps into this locking groove 535. The two sets of sliding devices 50 are in a connected state and can move uniformly when the trainer is exercising.

[0058] As shown in the attached Figure 4 figure, the support part 54 in this embodiment includes a first placement part 541 and a second placement part 542, and the two are of an integrated structure.

[0059] The surface of the first placement part 541 has a convex edge 543, and an accommodation groove is formed inside the convex edge 543. A contact pad 544 is installed in the accommodation groove. When the trainer uses the trainer for abdominal exercise mainly dominated by the legs, the trainer can kneel on the contact pad 544 with the knees, thereby protecting the knees. At the same time, place the lower legs on the second placement part 542 to play a supporting role and facilitate the trainer's force application action. When the trainer uses the trainer for abdominal exercise mainly dominated by the hands, the trainer can place the elbows on the contact pad 544, place the forearms on the second placement part 542, and hold the handle 55. While performing the abdominal exercise, it is also convenient for the elbow joint to apply force and reduce the burden on the forearms.

[0060] The acting surface of the first placement part 541 is not lower than the highest surface of the second placement part 542, that is, the upper surface of the contact pad 544 is higher than or flush with the upper surface of the second placement part 542. So that when performing abdominal exercise, the forearms or lower legs are inclined relative to the first placement part 541 when they are in contact with the second placement part 542, making the elbow joint or knees the main force-bearing points and facilitating the force application in the abdominal exercise.

[0061] Preferably, in this embodiment, one end of the second placement part 542 connected to the first placement part 541 is the large end part, and the end away from the first placement part 541 is the small end part. The width of the second placement part 542 gradually decreases from the large end part to the small end part; the width of the first placement part 541 is greater than or equal to the width of the large end part; so that the bearing area of the support part 54 is larger, improving the stability of the forearm or calf or buttocks or back on the sliding device 50. Both the first placement part 541 and the second placement part 542 can include soft materials laid on their surfaces to improve comfort. In addition, various matching patterns can be set on the upper surfaces of the first placement part 541 and the second placement part 542 to play an indicating role.

[0062] In some other embodiments, an arc-shaped depression is provided on the upper surface of the second placement part 542. The arc-shaped depression extends along the length direction of the bottom plate 10, and the arc-shaped depression is adapted to the shape of the forearm or calf to further improve the stability of the forearm or calf on the sliding device 50.

[0063] In this embodiment, the handle 55 includes a hard column body inside and a soft coating layer sleeved on the hard column body, so that the handle 55 has both supportability and good touch. A limiting protrusion is provided at the bottom of the handle 55. A limiting port and a limiting wall are provided in the handle mounting hole 545. The limiting port is adapted to the limiting protrusion, so that the bottom of the handle can be inserted into the handle mounting hole 545 and rotate relative to the handle mounting hole 545. After rotation, the limiting protrusion is located below the limiting wall, so that the handle is clamped with the handle mounting hole 545.

[0064] As shown in the attached Figure 4 figure, two handle mounting holes 545 are provided on the second placement part 542, and the two handle mounting holes 545 are spaced along the length direction of the bottom plate 10. The user can install the handle in the corresponding handle mounting hole 545 according to his own arm length. It should be noted that in this embodiment, the connection angle between the handle and the handle mounting hole 545 can be 90°; in other embodiments, the connection angle between the handle 55 and the handle mounting hole 545 can be less than 90°, so that the handle 55 is inclined relative to the support part 54, and the range of the connection angle is 60° to 90°.

[0065] As shown in the attached Figure 6As shown, during the abdominal exercise, the sliding device 50 requires some resilience so that the sliding device 50 can automatically reset, or the trainer needs to exert more force to move the sliding device 50, thereby increasing the training difficulty. Therefore, an elastic cord 56 and two elastic cord fixing members 57 are provided at the bottom of the base plate 10. The two elastic cord fixing members 57 are respectively connected to both ends of the elastic cord 56. One of the elastic cord fixing members 57 is detachably connected to the sliding device 50, and the other elastic cord fixing member 57 is detachably connected to the base plate 10. The initial position of the sliding device 50 is close to one end of the base plate 10. The trainer moves the sliding device 50 towards the middle of the base plate 10, thereby stretching the elastic cord 56. The elastic cord 56 exerts a resilience force on the sliding device 50. After the trainer withdraws the applied force, the sliding device 50 drives the trainer to reset. If the trainer needs to increase the training difficulty, the tightness of the screws at both ends of the elastic cord fixing member can be adjusted. By changing the pressure of the elastic cord fixing member on the elastic cord, the aperture inside the elastic cord 56 is changed. When the thread is tightened more, the tensile force of the elastic cord 56 is greater, and the force exerted by the trainer during training is also greater. Or the elastic cord fixing member can be disassembled, and the resilience force can be changed by replacing the elastic cord with other apertures or adjusting the actual effective length of the elastic cord.

[0066] In this embodiment, a fixed pulley 58 is also provided at the bottom of the base plate 10. One end of the elastic cord 56 is connected to the base plate 10 through an elastic cord fixing member, and the other end bypasses the fixed pulley 58 and is connected to the sliding device 50 through another elastic cord fixing member. Thus, without changing the length of the base plate 10, the length of the elastic cord 56 can be longer, thereby providing a larger adjustment space to meet the training requirements at different stages.

[0067] As shown in the Figure 1 attachment, a mobile phone holder 17 is respectively provided on both sides of the through hole. The mobile phone holder 17 is rotatably connected to the base plate 10. The mobile phone holder 17 can be used to place display devices such as tablets or mobile phones, so that the trainer can train along with the video, improving the training effect. Since the mobile phone holders 17 are provided at both ends in the length direction of the base plate 10, the trainer can set the sliding device 50 at one end of the base plate 10 and place the mobile phone on the mobile phone holder 17 at the other end.
