DETAILED DESCRIPTION
[0019] The following embodiments of the technical solution of the present invention will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention and are therefore only examples and are not intended to limit the scope of protection of the present invention. It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.
[0020] Reference Figure 1-Figure 5 , a multifunctional strength comprehensive training equipment, comprising: A mounting bracket 1 is provided with support frames 2 on both sides of the mounting bracket 1 in the width direction; A multi-posture support assembly 3, wherein the multi-posture support assembly 3 is fixedly connected to the upper ends of the two support frames 2; a tension driving device 4, one end of which is connected to a reel 5, and the other end of which is provided with a pulling assembly 6; and The tension drive device 4 is provided with a horizontal reciprocating component 7, and the multi-posture support component 3 is provided with an articulated connecting rod group 8. The output end of the horizontal reciprocating component 7 is connected to the articulated connecting rod group 8 for posture changes of the multi-posture support component 3.
[0021] By arranging support frames 2 on both sides of the arranged mounting bracket 1, the arranged multi-posture support assembly 3 is installed and supported; at the same time, a tension driving device 4 is arranged inside the support frame 2, and a reel 5 is connected to one end of the tension driving device 4, and the other end is subjected to tension, so that the horizontal reciprocating assembly 7 in the tension driving device 4 can perform reciprocating linear motion when the reel 5 is applied with force or relaxed, thereby making the multi-posture support assembly 3 deform under the control of the horizontal reciprocating assembly 7 and the articulated connecting rod group 8; furthermore, when the strength training operator lies or sits on the multi-posture support assembly 3 to perform tension training on his arms, the angle of the multi-posture support assembly 3 can be changed as the tension is pulled, thereby achieving better support for the operator's legs and back, thereby reducing the difficulty in the strength operation process and reducing the risk of injury.
[0022] It should be emphasized that, during the specific operation process, the strength training operator sits on the multi-posture support assembly 3, and pulls the pulling assembly 6 with both hands. During the pulling process, after driving the pulling drive device 4, the articulated connecting rod group 8 is controlled by the horizontal reciprocating assembly 7, so that the articulated connecting rod group 8 is in a retracted state after exerting force on the multi-posture support assembly 3, thereby allowing the strength trainer on the multi-posture support assembly 3 to retract his legs and abdomen; thus, during the pulling force process, the trainer's subsequent retracting action can be supported by the multi-posture support assembly 3 during the synchronous deformation process, which effectively reduces the difficulty of the trainer in the strength training process and reduces the problem of physical injury caused by imbalance due to excessive force during training.
[0023] Preferably, the multi-posture support assembly 3 includes a back support plate 9, a seat cushion plate 10 and a leg support plate 11 which are hinged in sequence, a first connecting rod 12 is provided at the position where the back support plate 9 and the seat cushion plate 10 are hinged, and the first connecting rod 12 is fixed vertically to the end of the back support plate 9, a second connecting rod 13 is provided at the position where the leg support plate 11 and the seat cushion plate 10 are hinged, and the second connecting rod 13 is fixed vertically to the end of the leg support plate 11.
[0024] The multi-posture support assembly 3 is arranged to be hinged in sequence by a back support plate 9, a seat cushion plate 10 and a leg support plate 11, and a first connecting rod 12 is provided at the hinged position of the back support plate 9 and the seat cushion plate 10, and a second connecting rod 13 is provided at the hinged position of the leg support plate 11 and the seat cushion plate 10; thereby, by driving the first connecting rod 12 and the second connecting rod 13, a force can be applied to the first connecting rod 12 and the second connecting rod 13 synchronously, so that the back support plate 9 and the leg support plate 11 can be rotated at a certain angle relative to the seat cushion plate 10.
[0025] As a preferred embodiment of the present invention, the surfaces of the back support plate 9, the seat plate 10 and the leg support plate 11 that are in contact with the trainee may be provided with elastic seat cushions to improve the comfort of use.
[0026] Preferably, the articulated connecting rod group 8 includes a horizontally arranged power transmission rod 15, a sleeve 16 fixedly connected to the bottom of the power transmission rod 15, and a reciprocating main shaft 17 movably arranged in the sleeve 16. The two ends of the power transmission rod 15 are respectively hinged to the first connecting rod 12 and the second connecting rod 13, the sleeve 16 and the reciprocating main shaft 17 are both vertically arranged, and the bottom of the reciprocating main shaft 17 is fixedly connected to the movable rack 18 in the horizontal reciprocating component 7.
[0027] Specifically, in order to achieve synchronous driving of the first connecting rod 12 and the second connecting rod 13, a power transmission rod 15 is provided to hinge the bottom of the first connecting rod 12 and the second connecting rod 13. Thus, when the power transmission rod 15 is translated in a straight line, the back support plate 9, the seat plate 10 and the leg support plate 11 can be relatively rotated and deformed through the first connecting rod 12 and the second connecting rod 13. For example, during the pulling process of strength training, combined with Figure 2 As shown in the figure, the power transmission rod 15 moves to the right, so that the leg support plate 11 and the seat plate 10, and the back support plate 9 and the seat plate 10 are perpendicular to each other, thereby forming a sitting posture between the back support plate 9, the seat plate 10 and the leg support plate 11, which satisfies the trainee's requirement that during the pulling force process, the trainee can obtain synchronous deformation support from the multi-posture support component 3 in the retracted posture.
[0028] Preferably, the horizontal reciprocating component 7 is also provided with a linear reciprocating rack 19, a gear set 20 for gear transmission with the linear reciprocating rack 19, and a linear movable sleeve rod 21.

The first gear 22 is meshed with the linear reciprocating rack 19, and the second gear 23 is meshed with the movable rack 18.
[0029] By configuring the horizontal reciprocating assembly 7, the pull rope 24 drives the linear reciprocating rack 19 therein to reciprocate during the pulling operation, thereby controlling the transmission of the power transmission rod 15. More specifically, the linear reciprocating rack 19 is meshed with the first gear 22 and transmits the rotation through the second gear 23. The upper end of the second gear 23 is placed in the linear movable sleeve 21 and meshed with the movable rack 18. Based on the fact that the movable rack 18 is linearly movable in the linear movable sleeve 21, the movable rack 18 can be reciprocated in a straight line. As a result, the reciprocating spindle 17, which is fixed perpendicular to the movable rack 18, can also be reciprocated in a straight line, thereby driving the sleeve 16 to move, so that the power transmission rod 15 fixed to the sleeve 16 can be controlled by power, and ultimately the deformation of the multi-posture support assembly 3 can be controlled.
[0030] Preferably, the linear reciprocating rack 19 is fixedly connected to the pull rope 24 in the reel 5 and reciprocates in the linear direction of the pull rope movement.

The linear reciprocating rack 19 is placed in the guide groove 26 and reciprocates.
[0031] In a specific implementation, the linear reciprocating rack 19 is fixedly connected to the pull rope 24. As a result, when the pull rope 24 is pulled and subjected to force at its end, combined with the reeling force of the reel 5, the pull rope 24 has a reciprocating effect, thereby driving the linear reciprocating rack 19 to perform linear reciprocating motion. Specifically, since a support plate 25 is fixedly installed at the bottom of the mounting bracket 1, and a guide groove 26 with an upward opening is formed on the support plate 25, the linear reciprocating rack 19 is placed in the guide groove 26, which improves the linear reciprocating motion of the linear reciprocating rack 19.
[0032] Preferably, the rotating main shaft 27 set in the gear group 20 is rotatably set in the width direction of the mounting bracket 1, and the upper side of the second gear 23 passes through the opening at the lower end of the linear movable sleeve rod 21 and is engaged with the tooth pattern set on the lower side of the movable rack 18.

[0034] Preferably, a sliding groove 28 is provided on the inner side wall of the linear movable sleeve rod 21 , and a matching sliding bar 29 is provided on the side of the movable rack 18 close to the sliding groove 28 , and the sliding bar 29 is placed in the corresponding sliding groove 28 .

[0036] Preferably, the leg support plate 11 includes a main body 30, two foot support rods 31 arranged in the main body 30 and a control component 32. The two foot support rods 31 are relatively telescopically arranged along the length direction of the main body 30. The control component 32 includes a driving gear 33 and a driven gear 34 rotatably arranged in the main body 30 and a rack rod 35 fixedly connected to the end of the foot support rod 31.

The driven gear 34 and the driving gear 33 are meshed with each other and the driving gear 33 is driven by a drive motor 36 fixedly arranged at the bottom of the main body 30.
[0037] Reference Figure 5In the process of the trainee pulling and bearing force, in order to enable the legs to bear force better, a foot support rod 31 that can be telescopically adjusted is provided in the leg support plate 11, thereby meeting the needs of different situations and providing better force support for the trainee's legs and feet, so as to improve better force operation; specifically, a control component 32 is provided in the body 30, and the control component 32 controls the telescopic movement of the foot support rod 31, and the driving gear 33 in the control component 32 drives the driven gear 34, and the driving gear 33 and the driven gear 34 are engaged with the rack rod 35, thereby realizing the control of the foot support rod 31 With respect to the extension and retraction of the main body 30, since it is necessary to support the two legs of the trainee, the driving gear 33 and the driven gear 34 are relatively meshed and mesh with the corresponding rack rods 35, thereby realizing the relative arrangement of the two foot support rods 31 in the main body 30 at the same time; in one embodiment, in order to prevent the rack rod 35 from completely sliding out of the main body 30, an anti-falling block 42 is provided at the end of the rack rod 35 placed in the main body 30, and a limit block 43 is provided in the main body 30, and the anti-falling block 42 cooperates with the limit block 43 to realize the anti-falling arrangement of the rack rod 35 in the main body 30.
