Technical Field

[0001] This utility model relates to the field of rehabilitation equipment, and in particular to a foldable and portable lower limb rehabilitation pedal exercise device. Background Technology

[0002] Lower limb rehabilitation training is an important means to help patients restore muscle strength, joint mobility and coordination.

[0003] Traditional pedaling training equipment (such as stationary exercise bikes) is bulky and non-foldable, which cannot meet the needs of home rehabilitation or mobile medical scenarios.

[0004] Therefore, in view of the above situation, there is an urgent need to develop a foldable and portable lower limb rehabilitation pedal exercise device to overcome the shortcomings in current practical applications. Utility Model Content

[0005] The purpose of this utility model embodiment is to provide a foldable and portable lower limb rehabilitation pedal exercise device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A foldable and portable lower limb rehabilitation pedal exercise device includes a base plate, on which a base is fixedly connected. A Y-shaped support frame is hinged to the base. A turntable is disposed inside the Y-shaped support frame. Sleeves are fixedly connected to both ends of the turntable, and the sleeves are rotatably connected to the two side plates of the Y-shaped support frame. A connecting rod is snapped into each sleeve. A Z-shaped rod is fixedly connected to the other end of each connecting rod, and a foot pedal is fitted to the other end of each Z-shaped rod. A locking assembly is fixedly disposed on the side wall of the Y-shaped support frame, and a locking hole is provided on the base plate. The Y-shaped support frame is fixed by the locking assembly and the locking hole engaging.

[0008] In a further technical solution, both the inner wall of the sleeve and the connecting rod are square.

[0009] A further technical solution includes a locking assembly comprising a placement plate, a support plate, a T-shaped rod, a fixing plate, and a spring; the placement plate is fixedly connected to the outer wall of the side plate of the Y-shaped support frame, the support plates are fixedly connected to the placement plate, the T-shaped rod is slidably connected between the two support plates, and one end of the vertical rod of the T-shaped rod is inserted into a locking hole, the fixing plate is fixedly sleeved on the outer wall of the vertical rod of the T-shaped rod, and a spring is fixedly provided between the fixing plate and the support plate near the crossbar of the T-shaped rod.

[0010] In a further technical solution, a reset plate is fixedly connected to the outer wall of the fixing plate, and a loop-shaped limiting plate is also fixedly connected to the placement plate, and the reset plate is slidably connected to the inner wall of the loop-shaped limiting plate.

[0011] A further technical solution is that when the vertical rod of the T-shaped rod is inserted into the locking hole, the distance between the horizontal rod of the T-shaped rod and the centerline of the sleeve is larger than the rotation radius of the Z-shaped rod.

[0012] A further technical solution is that the base plate is provided with an inclined sliding groove, and one end of the inclined sliding groove is connected to the locking hole.

[0013] In summary, the embodiments of this utility model have the following beneficial effects compared with the prior art:

[0014] 1. By adjusting the position of the Y-shaped support frame, the Y-shaped support frame rotates relative to the base. Then, the Y-shaped support frame is locked and fixed by the locking assembly and locking hole. After that, the connecting rod is inserted into the sleeve, and then it can be used for exercise. When folding is required, the connecting rod is taken out from the sleeve, and then the reset plate is pushed upward to slide along the inner wall of the U-shaped limit plate. Then the reset plate drives the fixed plate to move upward. Next, the fixed plate drives the T-shaped rod to move upward until the vertical part of the T-shaped rod is disengaged from the locking hole. During this process, the fixed plate compresses the spring. Then, the Y-shaped support frame can be folded away from the locking hole. The structure is simple, can be folded, and is easy to disassemble, thus occupying little space and being easy to carry.

[0015] 2. The relative position between the two Z-shaped rods can be adjusted by using a connecting rod and a sleeve, thereby adjusting the relative position of the two legs and enabling various modes of movement.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0024] like Figures 1-4 As shown, this utility model embodiment provides a foldable and portable lower limb rehabilitation pedal exercise device, including a base plate 1, a base 2 fixedly connected to the base plate 1, a Y-shaped support frame 3 hinged to the base 2, a turntable 4 disposed inside the Y-shaped support frame 3, sleeves 5 fixedly connected to both ends of the turntable 4, and the sleeves 5 rotatably connected to the two side plates of the Y-shaped support frame 3 respectively, a connecting rod 11 being snapped into each sleeve 5, a Z-shaped rod 6 fixedly connected to the other end of each connecting rod 11, and a foot pedal 7 rotatably connected to the other end of each Z-shaped rod 6, a locking assembly 8 fixedly disposed on the side wall of the Y-shaped support frame 3, and a locking hole 9 opened on the base plate 1, the Y-shaped support frame 3 being fixed by the cooperation of the locking assembly 8 and the locking hole 9.

[0025] Furthermore, both the inner wall of the sleeve 5 and the connecting rod 11 are square, which allows for quick installation and disassembly and effectively reduces the space occupied.

[0026] like Figures 1-3 As shown, the locking assembly 8 includes a placement plate 81, a support plate 82, a T-shaped rod 83, a fixing plate 84, and a spring 86; the placement plate 81 is fixedly connected to the outer wall of the side plate of the Y-shaped support frame 3, and the support plates 82 are fixedly connected to the placement plate 81. The T-shaped rod 83 is slidably connected between the two support plates 82, and one end of the vertical rod of the T-shaped rod 83 is inserted into the locking hole 9. The fixing plate 84 is fixedly sleeved on the outer wall of the vertical rod of the T-shaped rod 83, and a spring 86 is fixedly provided between the fixing plate 84 and the support plate 82 near the horizontal rod of the T-shaped rod 83.

[0027] Furthermore, a reset plate 85 is fixedly connected to the outer wall of the fixing plate 84, and a loop-shaped limiting plate 87 is also fixedly connected to the placement plate 81, and the reset plate 85 is slidably connected to the inner wall of the loop-shaped limiting plate 87.

[0028] Furthermore, when the vertical rod of the T-shaped rod 83 is inserted into the locking hole 9, the distance between the horizontal rod of the T-shaped rod 83 and the axis of the sleeve 5 is larger than the rotation radius of the Z-shaped rod 6, thereby preventing the foot pedal 7 from colliding with the loop-shaped limit plate 87 or the T-shaped rod 83.

[0029] Furthermore, the base plate 1 is provided with an inclined sliding groove 10, and one end of the inclined sliding groove 10 is connected to the locking hole 9. The inclined sliding groove 10 has a certain angle with the upper end face of the base plate 1, so that the lower end of the vertical rod of the T-shaped rod 83 can slide into the locking hole 9 along the inner wall of the inclined sliding groove 10.

[0030] In practical applications, when it is necessary to fold the Y-shaped support frame 3, push the reset plate 85 upward and slide it along the inner wall of the U-shaped limiting plate 87. Then, the reset plate 85 drives the fixing plate 84 to move upward. Next, the fixing plate 84 drives the T-shaped rod 83 to move upward until the vertical part of the T-shaped rod 83 disengages from the locking hole 9. During this process, the fixing plate 84 compresses the spring 86. Then, fold the Y-shaped support frame 3 away from the locking hole 9. When it is necessary to unfold the Y-shaped support frame 3, adjust the position of the Y-shaped support frame 3. During this process, the lower end of the vertical rod of the T-shaped rod 83 first contacts the inner wall of the inclined slide groove 10 and slides along the inner wall of the inclined slide groove 10 until it slides into the locking hole 9. The spring 86 always applies an elastic force along the axis of the vertical rod of the T-shaped rod 83 to the fixing plate 84, so that the vertical part of the T-shaped rod 83 can be firmly inserted into the locking hole 9 through the fixing plate 84, thereby fixing the Y-shaped support frame 3.

[0031] It is understandable that when the two Z-shaped rods 6 are symmetrically arranged about the axis of the sleeve 5, (such as...) Figure 1 (As shown in the unfolded state), the trainee can adopt a step-by-step training mode of alternating force exertion with both legs; when the two Z-shaped bars 6 are symmetrically arranged about the turntable 4, the trainee can perform a coordinated training mode of simultaneous force exertion with both legs.

[0032] In this embodiment of the utility model, by adjusting the position of the Y-shaped support frame 3, the Y-shaped support frame 3 rotates relative to the base 2. Then, the Y-shaped support frame 3 is locked and fixed by the locking assembly 8 and the locking hole 9. After that, the connecting rod 11 is inserted into the sleeve 5, and then exercise can begin. When folding is required, the connecting rod 11 is removed from the sleeve 5, and then the reset plate 85 is pushed upward to slide along the inner wall of the U-shaped limiting plate 87. Then, the reset plate 85 drives the fixing plate 84 to move upward. Next, the fixing plate 84 drives the T-shaped rod 83 to move upward until the vertical part of the T-shaped rod 83 disengages from the locking hole 9. During this process, the fixing plate 84 compresses the spring 86. Then, the Y-shaped support frame 3 can be folded away from the locking hole 9. The structure is simple, foldable, and easy to disassemble, thus occupying little space and being easy to carry. The relative position between the two Z-shaped rods 6 can be adjusted by the cooperation of the connecting rod 11 and the sleeve 5, thereby adjusting the relative position of the two legs and enabling various modes of exercise.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
