DETAILED DESCRIPTION

[0024] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0025] Example 1

[0026] A multifunctional chair for fitness, such as Figure 1-8 As shown, it includes a bracket 1, a support frame 2, a seat plate 3, a back plate 4, a back support assembly 5, a foot placement assembly 6 and a fixing assembly 7. The bracket 1 is provided with a support frame 2, the top of the support frame 2 is provided with a seat plate 3, the left part of the seat plate 3 is rotatably provided with a back support assembly 5, the left part of the bracket 1 is provided with a foot placement assembly 6, the right part of the bracket 1 is provided with a fixing assembly 7, and the upper part of the support frame 2 is provided with a fixing assembly 7.

[0027] When using the device, the user sits on the seat plate 3, with the back against the back plate 4, and the feet are placed on the foot placement assembly 6. When exercising, the back support assembly 5 can support the back plate 4. At the same time, the user can adjust whether the back plate 4 rotates through the fixing assembly 7 according to the needs of the exercise.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, the back support assembly 5 includes a support plate 51, a torsion spring 52 and a swing plate 53. The support plate 51 is provided on the left part of the bracket 1, and a swing plate 53 is rotatably provided on the upper part of the support plate 51. The swing plate 53 is in contact with the back plate 4, and a row of torsion springs 52 are connected between the swing plate 53 and the support plate 51.

[0029] When the user pushes the back plate 4 to rotate downward, the back plate 4 will push the swing plate 53 to rotate downward on the support plate 51, and the torsion spring 52 will be deformed. When the user stands up, under the action of the torsion spring 52 restoring, the swing plate 53 will drive the back plate 4 to rotate upward and reset, so that the back plate 4 can be supported.

[0030] like Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the foot placement assembly 6 includes a first guide rod 61, a movable frame 62, a first spring 63, a connecting seat 64, a telescopic rod 65, a second spring 66, a placement plate 67 and a second guide rod 68. The first guide rod 61 is symmetrically arranged front and back on the right part of the bracket 1, and the movable frame 62 is slidably arranged between the two first guide rods 61. The first spring 63 is connected between the first guide rod 61 and the movable frame 62. A connecting seat 64 is provided at the lower part of the movable frame 62. The telescopic rod 65 is symmetrically arranged front and back on the connecting seat 64. The second spring 66 is connected between the extended end and the contracted end of the telescopic rod 65. A placement plate 67 is provided between the tops of the two telescopic rods 65. The placement plate 67 is slidably connected to the movable frame 62. The second guide rod 68 is symmetrically arranged front and back on the lower part of the movable frame 62. The second guide rod 68 is slidably connected to the placement plate 67.

[0031] When using the device, the user places his feet on the placement plate 67. When the user does leg exercises, the user pushes his feet to the right, thereby pushing the placement plate 67 to move to the right, thereby driving the movable frame 62 to slide to the right on the first guide rod 61, and the first spring 63 is deformed. When the user unloads the force, under the action of the first spring 63 being reset, the movable frame 62 drives the placement plate 67 to move to the left and reset. When the user does sit-ups, the user exerts force downward with his feet, thereby pushing the placement plate 67 to slide downward on the movable frame 62, the telescopic rod 65 contracts, and the second spring 66 is deformed. When the user unloads the force, under the action of the second spring 66 being reset, the telescopic rod 65 is extended and reset, and the extension of the telescopic rod 65 drives the placement plate 67 to move upward and reset. In this way, the user's feet can be placed to cooperate with the user in exercise.

[0032] like Figure 1 , Figure 5 and Figure 6As shown, the fixing assembly 7 includes a mounting block 71, a telescopic rod 72, a third spring 73 and a clamping block 74. The supporting frame 2 is provided with mounting blocks 71 on both the front and rear sides, and the mounting blocks 71 are provided with telescopic rods 72. The extended ends of the telescopic rods 72 are slidably connected to the mounting blocks 71, and the third spring 73 is connected between the extended ends of the telescopic rods 72 and the mounting blocks 71. The back panel 4 is provided with clamping blocks 74 on both the front and rear sides, and the telescopic rods 72 cooperate with the clamping blocks 74.

[0033] When using the device, the user can adjust the angle of the backboard 4 according to the needs of different sports. When the user does not need the backboard 4 to rotate, the user pushes the telescopic rod 72 to extend and get into the block 74, and the third spring 73 is deformed. Then, the user fixes the telescopic rod 72 with a tool. When the user does sit-ups, the angle of the backboard 4 is not enough and the user cannot lie down. At this time, the backboard 4 needs to rotate. The user releases the telescopic rod 72. Under the action of the third spring 73 resetting, the telescopic rod 72 is shortened and no longer gets stuck in the block 74. In this way, the rotation state of the backboard 4 can be adjusted according to the needs of the user.

[0034] Example 2

[0035] On the basis of Example 1, Figure 1 and Figure 6 As shown, an adjustment component 8 is also included, and the adjustment component 8 includes a slider 81, a slide bar 82, a fourth spring 83, a slide rail 84, a sliding wedge plate 85 and a connecting rod 86. Sliders 81 are provided on the front and rear sides of the left part of the placement plate 67. Slide bars 82 are slidably provided on the slider 81. The fourth spring 83 is connected between the slider 81 and the slider 81. Slide rails 84 are provided on the front and rear sides of the upper part of the bracket 1. Sliding wedge plates 85 are slidably provided on the slide rails 84. The sliding wedge plates 85 cooperate with the telescopic plug rod 72. A connecting rod 86 is rotatably provided between the sliding wedge plate 85 and the slide bar 82.

[0036] The sliding wedge plate 85 cooperates with the telescopic insertion rod 72 to put the third spring 73 in a stretched state. When the user exerts force to the right with his feet, the placement plate 67 drives the slider 81 to slide to the right in the slider 82, and the fourth spring 83 is deformed. When the user unloads force with his feet, under the action of the fourth spring 83 returning to its original position, the slider 81 slides to the left and returns to its original position. When the user does sit-ups and exerts force with his feet downward, the placement plate 67 drives the slider 81 to move downward, and the slider 81 moves downward and drives the sliding wedge plate 85 to slide to the right through the connecting rod 86 and no longer squeezes the telescopic insertion rod 72. At this time, under the action of the third spring 73 returning to its original position, the telescopic insertion rod 72 shortens and no longer fixes the back plate 4. The back plate 4 can rotate downward to facilitate the user's exercise. In this way, the rotation state of the back plate 4 can be automatically adjusted.

[0037] On the basis of Example 1, Figure 1and Figure 7 As shown, it also includes a force changing component 9, which includes a hanging rod 91, a fifth spring 92 and a hook 93. The hanging rod 91 is provided at the lower part of the bracket 1, and a row of fifth springs 92 is provided at the lower part of the movable frame 62. The tail ends of the fifth springs 92 are all provided with hooks 93, and the hooks 93 are all matched with the hanging rod 91.

[0038] When using the device, the user hangs different numbers of hooks 93 on the hanging rod 91 as needed. When the user pushes his feet to the right, the resistance becomes larger under the action of the fifth spring 92. In this way, the intensity of exercise can be adjusted according to the needs of the user.

[0039] On the basis of Example 1, Figure 1 and Figure 8 As shown, it also includes a clamping assembly 10, which includes a rotating rod 102 and a clamping plate 103. Two clamping grooves 101 are opened on the front and back sides of the bottom of the placement plate 67, and two rotating rods 102 are rotatably provided on the front and back sides of the connecting seat 64. A clamping plate 103 is provided on the top of the rotating rod 102, and the clamping plate 103 cooperates with the clamping groove 101.

[0040] When using the device, when the placement plate 67 slides downward to contact the clamping plate 103, the user rotates the rotating rod 102, thereby driving the clamping plate 103 to rotate and clamp the clamping slot 101. In this way, the placement plate 67 can be clamped when the user is exercising, thereby making the sliding wedge plate 85 relatively fixed and no longer sliding.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
