Technical Field

[0001] This utility model relates to the field of medical rehabilitation training equipment, and in particular to a hamstring stretcher. Background Technology

[0002] During clinical rehabilitation, many patients experience abnormal hamstring muscle tone in the lower limbs. Currently, stretching therapy is typically performed using a stretching device to address this condition.

[0003] In the existing technology, some stretchers mainly consist of a frame and a T-shaped orthotic shoe, with the T-shaped orthotic shoe fixed on the frame. During stretching treatment, the patient lies supine with their lower limbs raised and their feet and calves fixed in the T-shaped orthotic shoe, thereby stretching the patient's hamstring muscles.

[0004] However, T-shaped orthopedic shoes of the same size are usually only suitable for patients whose foot and calf sizes are not much different. When the foot and calf sizes of different patients are much different, it is usually necessary to remove and replace the T-shaped orthopedic shoes on the frame. This requires a variety of T-shaped orthopedic shoes of different sizes, and repeated disassembly and assembly is also quite troublesome. Utility Model Content

[0031] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-8 As shown, this embodiment discloses a hamstring stretcher, including an adjustable T-shaped shoe 1, which is mounted on a support body 2. The adjustable T-shaped shoe 1 includes a base 11 connected to the support body 2. Connecting frames 12 are slidably connected to both sides of the base 11. The connecting frames 12 are limited and fixed or released by corresponding limiting components 13. Both connecting frames 12 are provided with baffles 14, and a detachable fixing strap 15 is provided between the two baffles 14.

[0033] In this embodiment, two guard edges 14 are respectively fixed to the opposite sides of the two connecting frames 12. The guard edges 14 are made of flexible material. Multiple fixing straps 15 can be provided between the two guard edges 14. Each fixing strap 15 includes two corresponding strip-shaped bodies 151. One end of each strip-shaped body 151 is fixedly connected to the corresponding guard edge 14. The other side of each strip-shaped body 151 is fixed with a hook side and a loop side of Velcro. Through the detachable fixing connection between the hook side and the loop side, the feet and lower legs of different patients can be fixed or unfixed. As an optional embodiment, the two corresponding strip-shaped bodies 151 can be detachably connected by forming a slipknot.

[0034] When dealing with patients with significantly different foot and calf sizes, the position of the corresponding connecting frame 12 can be adjusted after the limiting component 13 releases the limiting of the corresponding connecting frame 12. After the positions of the two connecting frames 12 are adjusted, the limiting component 13 limits and fixes the corresponding connecting frame 12 respectively. At this time, the distance between the two guardrails 14 can accommodate the patient's foot and calf. By connecting the corresponding strips 151 on the two guardrails 14 respectively, and making the guardrails 14 and strips 151 cover the patient's foot and calf, the fixation of the patient's foot and calf can be completed.

[0035] By adopting this solution, the present invention can adjust the distance between the two connecting frames 12 and the guard 14 through the above-mentioned structural settings, making it suitable for patients with large differences in foot and calf size, thus improving the applicability of the present invention. At the same time, the present invention no longer requires the provision of multiple T-shaped orthopedic shoes of different sizes, and eliminates the complicated operation of repeatedly disassembling and assembling T-shaped orthopedic shoes, thus improving convenience.

[0036] Further optimize the plan, such as Figure 2As shown, the base 11 includes an L-shaped plate 111 and a connecting beam 112 fixed at the outer corner of the L-shaped plate 111. The L-shaped plate 111 is rotatably connected to the support body 2 through the connecting beam 112. The connecting frame 12 is slidably connected to the L-shaped plate 111 and is limited or released from the limit by the corresponding limiting component 13.

[0037] In this embodiment, as Figure 3 As shown, multiple sliding grooves 1110 are provided on both sides of the vertical and horizontal sections of the L-shaped plate 111. Sliding rods 121 are slidably connected in the sliding grooves 1110 on the same side. The ends of the sliding rods 121 on the same side are fixedly connected to a connecting rod 122. The sliding rods 121 and the connecting rods 122 on the same side together form a connecting frame 12. The baffle 14 is fixedly connected to the corresponding connecting rod 122.

[0038] When the limiting component 13 releases its restriction on the connecting frame 12, the sliding rod 121 moves in the corresponding sliding groove 1110 by moving the connecting rod 122, which can adjust the position of the guard 14. By rotating the L-shaped plate 111 around the axis of the connecting beam 112, the angle of the L-shaped plate 111 can be adjusted so that the patient's foot can fit in close contact with the L-shaped plate 111. In order to improve the comfort of the patient's foot, a soft pad, such as a cotton pad, is placed on the inner surface of the L-shaped plate 111.

[0039] Further optimize the plan, such as Figure 3 As shown, the limiting component 13 includes a connector 131 connected to the bracket body 2. The connector 131 is provided with a limiting part 132, which is inserted and engaged with the corresponding connecting frame 12.

[0040] In this embodiment, connector 131 is used to install limiting part 132, which is located below the corresponding connecting frame 12; connector 131 is fixedly connected to the bracket body 2. Through the insertion and engagement between the limiting part 132 and the corresponding connecting frame 12, the connecting frame 12 can be limited and fixed or released from the limiting and fixed position.

[0041] Further optimize the plan, such as Figures 4-6 As shown, the limiting part 132 includes a threaded sleeve 1321 that is fixedly connected to the connecting member 131. A limiting bolt 1322 is threadedly connected in the threaded sleeve 1321, and the screw end of the limiting bolt 1322 is inserted into the corresponding connecting bracket 12.

[0042] In this embodiment, both the threaded sleeve 1321 and the limiting bolt 1322 are arranged vertically and located below the corresponding connecting frame 12. By tightening the limiting bolt 1322 and inserting or releasing its threaded end into the connecting frame 12, the connecting frame 12 can be limited and fixed or released from its limiting and fixed position.

[0043] Further optimize the plan, such as Figures 4-6 As shown, the connecting frame 12 is provided with a plurality of spaced limiting grooves 1210 along its direction of movement. The limiting bolt 1322 corresponds to the movement trajectory of the plurality of limiting grooves 1210, and the screw end of the limiting bolt 1322 is inserted into one of the limiting grooves 1210.

[0044] In this embodiment, multiple limiting grooves 1210 arranged along the movement direction of the connecting frame 12 form a group, and multiple groups of limiting grooves 1210 can be provided on each connecting frame 12. Each group of limiting grooves 1210 corresponds to a limiting bolt 1322; the width direction of the limiting groove 1210 (e.g., Figure 6 As shown) has the same outer diameter as the limiting bolt 1322, and the length direction of the limiting groove 1210 (as shown) is the same. Figure 4 , Figure 5 (As shown) is larger than the outer diameter of the limiting bolt 1322. After the position of the retaining edge 14 and the angle of the L-shaped plate 111 are adjusted, the connecting frame 12 can be fixed by inserting the limiting bolt 1322 into one of the corresponding limiting slots 1210.

[0045] Further optimize the plan, such as Figure 7 As shown, the main body 2 of the bracket includes a base 21, and a mounting bracket 23 is hinged to one side of the base 21 via an angle adjuster 22. An adjustable T-shaped shoe 1 is mounted on the mounting bracket 23.

[0046] In this embodiment, the base 21 is used to support the work surface, and the angle adjuster 22 is used to adjust the angle of the mounting bracket 23, which can raise the adjustable T-shaped shoe 1 to different heights, thereby enabling the patient to perform hamstring stretching training of different intensities.

[0047] Further optimize the plan, such as Figure 7 As shown, the angle adjuster 22 includes an adjustment plate 221 connected to the base 21. A hinge shaft 222 is provided on the adjustment plate 221. The mounting frame 23 is hinged to the adjustment plate 221 through the hinge shaft 222. A limit component 223 is provided on the mounting frame 23. The mounting frame 23 is limited to the adjustment plate 221 through the limit component 223.

[0048] In this embodiment, the adjusting plate 221 is a quarter-circle structure, vertically arranged, and fixedly connected to the base 21. The hinge shaft 222 is horizontally installed at the corner of the adjusting plate 221, and the mounting frame 23 can rotate around the axis of the hinge shaft 222. The adjusting plate 221 is provided with a plurality of spaced and arc-shaped limiting holes 2210, and the plurality of limiting holes 2210 correspond to the movement trajectory of the limiting component 223. The limiting component 223 and the limiting holes 2210 are inserted and engaged, which can limit and fix the mounting frame 23 and release the limiting fixation.

[0049] Limiting component 223 is set on mounting bracket 23. The structure of limiting component 223 is the same as that of limiting part 132. That is, limiting component 223 can be a structure in which threaded sleeve 1321 and limiting bolt 1322 are threadedly engaged. By turning the limiting bolt 1322 and inserting its screw end into one of the limiting holes 2210, the mounting bracket 23 can be fixed.

[0050] Further optimize the plan, such as Figure 7 As shown, the base 21 includes at least two sets of telescopic structures 211 arranged at intervals. An angle adjuster 22 is provided at the fixed end of the telescopic structure 211, and both the fixed end and the movable end of the telescopic structure 211 are provided with adjustable support feet 212.

[0051] In this embodiment, there are two sets of telescopic structures 211. The fixed ends of the two sets of telescopic structures 211 are located on the same side and arranged side by side. The telescopic ends of the two sets of telescopic structures 211 are connected as one unit by connecting rod 122. The size of the base 21 can be adjusted by extending or shortening the telescopic structure 211. The telescopic structure 211 can be supported by the adjustable support foot 212 pressing against the working surface.

[0052] Alternatively, the base 21 may include at least two sets of spaced-apart fixing structures, with an angle adjuster 22 disposed at one end of each fixing structure, and adjustable support feet 212 provided at both ends of the telescopic structure 211. The two sets of fixing structures may be arranged side by side, or in a V-shape or trapezoidal arrangement.

[0053] Further optimize the plan, such as Figure 8 As shown, the adjustable support foot 212 includes a height adjustment component 2121 disposed at the fixed end or the movable end of the telescopic structure 211. A support plate 2122 is connected to the movable end of the height adjustment component 2121, and the support plate 2122 is located below the telescopic structure 211.

[0054] In this embodiment, the height adjustment component 2121 is used to adjust the height of the support plate 2122. When the support plate 2122 is pressed against the working surface, it can support the telescopic structure 211. The height adjustment component 2121 includes an adjustment sleeve 21211 fixedly connected to the fixed end or movable end of the telescopic structure 211. A vertically arranged adjustment bolt 21212 is threaded into the adjustment sleeve 21211. The screw end of the adjustment bolt 21212 passes downward through the adjustment sleeve 21211 and is fixedly connected to the support plate 2122. By turning the adjustment bolt 21212, the support plate 2122 can be moved vertically, thus pressing the support plate 2122 against the working surface.

[0055] Alternatively, the height adjustment assembly 2121 may include a linear drive component fixedly connected to either the fixed end or the movable end of the telescopic structure 211. The actuating end of the linear drive component extends downward and is fixedly connected to the support plate 2122. The linear drive component may be configured as a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder. By controlling the linear drive component and extending or retracting its actuating end, the support plate 2122 can be driven to move vertically.

[0056] Further optimize the plan, such as Figure 7 As shown, the mounting frame 23 includes a telescopic structure 231 corresponding to the telescopic structure 211. The fixed end of the telescopic structure 231 is hinged by an angle adjuster 22. The telescopic end of the telescopic structure 231 is connected to a support frame 232. The adjustable T-shaped shoe 1 is mounted on the support frame 232.

[0057] In this embodiment, there are two sets of telescopic structures 231. The fixed ends of the two sets of telescopic structures 231 are located on the same side and side by side. The fixed end of each set of telescopic structures 231 is hinged to the corresponding telescopic structure 211 via an angle adjuster 22. The support frame 232 is used to connect the fixed ends of the two sets of telescopic structures 231 into a whole and to install the adjustable T-shaped shoe 1. By extending or shortening the telescopic ends of the telescopic structures 231, the position of the adjustable T-shaped shoe 1 can be adjusted, improving its applicability to different patients.

[0058] As an optional embodiment, the mounting frame 23 may include a second fixing structure, one end of which is hinged by an angle adjuster 22, and the other end is fixed with a support frame 232, on which an adjustable T-shaped shoe 1 is mounted.

[0059] Further optimize the plan, such as Figure 7 As shown, the telescopic structure 211 includes a mounting sleeve 2111 and a rod 2112 slidably connected in the mounting sleeve 2111. The mounting sleeve 2111 is provided with a fixing part 2113. The rod 2112 is fixedly connected to or de-fixedly connected to the mounting sleeve 2111 through the fixing part 2113.

[0060] In this embodiment, after the fixing part 2113 releases the fixing of the rod 2112, the size of the telescopic structure 211 can be adjusted by sliding the rod 2112 in the mounting sleeve 2111.

[0061] In a further optimized design, the fixing part 2113 is located at the end of the top surface of the mounting sleeve 2111. The structure of the fixing part 2113 is the same as that of the limiting part 132, that is, the structure of the fixing part 2113 is a structure in which the threaded sleeve 1321 and the limiting bolt 1322 are threadedly engaged. The top surface of the rod body 2112 is provided with multiple fixing holes 1 whose movement trajectories correspond to the fixing part 2113 at intervals. By turning the limiting bolt 1322 and inserting its screw end into one of the fixing holes 1, the rod body 2112 can be fixed.

[0062] Further optimize the plan, such as Figure 8 As shown, the telescopic structure 231 includes a mounting sleeve 2311 and a rod 2312 slidably connected in the mounting sleeve 2311. The mounting sleeve 2311 is provided with a fixing part 2313. The rod 2312 is fixedly connected to or de-fixedly connected to the mounting sleeve 2311 through the fixing part 2313.

[0063] In this embodiment, when the fixing part 2313 releases the fixing of the rod 2312, the size of the telescopic structure 231 can be adjusted by sliding the rod 2312 in the mounting sleeve 2111, thereby adjusting the position of the adjustable T-shaped shoe 1.

[0064] In a further optimized design, the fixing part 2313 is located at the end of the top surface of the mounting sleeve 2311. The structure of the fixing part 2313 is the same as that of the limiting part 132, that is, the structure of the fixing part 2313 is a structure in which the threaded sleeve 1321 and the limiting bolt 1322 are threadedly engaged. The top surface of the rod body 2312 is provided with multiple fixing holes 2 at intervals, all of which correspond to the movement trajectory of the fixing part 2313. By turning the limiting bolt 1322 and inserting its screw end into one of the fixing holes 2, the rod body 2312 can be fixed.

[0065] It should be noted that, in this utility model, the base 21 preferably includes two telescopic structures 211, and the mounting bracket 23 preferably includes two telescopic structures 231; the width of the base 21, that is, the distance between the two telescopic structures 211, is approximately 50cm; the length of the telescopic structures 211 and 231 when retracted to their shortest length is approximately 50cm; when extended to their maximum length, the length of the telescopic structures 211 and 231 is approximately 90cm; the mounting bracket 23 can be adjusted to a horizontal state.

[0066] Further optimize the plan, such as Figure 7 As shown, the fixed end of the telescopic structure 231 or the fixed structure 2 is provided with a detachable fixing strap 233 at the end away from the adjustable T-shaped shoe 1.

[0067] In this embodiment, the second fixing strap 233 is an integral structure with a width of approximately 10cm. A connecting sleeve is provided on one side of the second fixing strap 233, allowing it to be movably fitted onto the fixed end of one of the telescopic structures 231 or onto the second fixing structure. This allows the second fixing strap 233 to slide along the length of the fixed end of the telescopic structure 231 or the second fixing structure. After passing through the fixed end of another telescopic structure 231 or the bottom of the second fixing structure on the side away from the connecting sleeve, the second fixing strap 233 wraps back from the top to the side near the connecting sleeve. The hook and loop sides of the Velcro fastener detachably connect the wrapped portion of the second fixing strap 233 to the portion below it, enabling the second fixing strap 233 to apply a downward force to the patient's leg, thereby increasing the stretching strength of the patient's hamstring muscles.
