Description

Technical Field

[0001] This utility model relates to the field of rehabilitation exercise equipment technology, and in particular to a decompression-type electric exerciser for hip and knee joint rehabilitation. Background Technology

[0002] Rehabilitation exercise equipment is designed specifically for rehabilitation medicine to help people with functional impairments improve their functional status. These devices include a variety of appliances, instruments, technologies, and software. In particular, decompression-type electric rehabilitation exercisers for hip and knee joints are an important type of equipment. They mainly serve the rehabilitation training of the hip and knee joints. This equipment accelerates the rehabilitation process by promoting the recovery of muscle strength and improving the flexibility and stability of the joints.

[0003] Chinese patent discloses a pressure-reducing electric rehabilitation exerciser for hip and knee joints (authorization announcement number CN204364362U). The patented technology controls the motor to drive the transmission to the reducer, and the reducer outputs the transmission to the rotating wheel. The rotating wheel drives the connecting rod to move up and down, which in turn drives the thigh support plate to move up and down, and drives the lower leg support plate to extend and retract. The patient sits on the fixed seat and places his / her legs on the support plate to exercise the hip and knee joints without bearing any weight. Both legs can be exercised at will. Similarly, the backrest can also move up and down, so as to achieve comfortable and weightless exercise of the hip and knee joints for the patient.

[0004] Regarding the aforementioned and existing related technologies, the inventor believes that the following defects often exist: In the existing and the cases mentioned above, the backrests of the devices can mostly only be adjusted in a simple angle, and cannot be adjusted in front and back position. This makes it impossible for people of different heights and leg lengths to fully use the device, resulting in limitations in the use of the device. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the backrest of the existing technology cannot be adjusted. To address this, we propose a pressure-reducing electric exercise device for hip and knee joint rehabilitation.

[0006] To achieve the above objectives, this application adopts the following technical solution: a decompression-type electric rehabilitation exerciser for hip and knee joints, comprising a device base, an air pump installed inside the device base, a U-shaped contact plate installed at the top of the air pump, a cushion installed at the top of the device base, an electric angle adjustment mechanism installed on one side of the device base, the cushion being electrically connected to the electric angle adjustment mechanism, two adjustment slots opened at the top of the device base, an adjustment block being slidably connected inside the adjustment slots, a sliding rod being slidably connected inside the adjustment block, a limiting thread being opened on the surface of the sliding rod, a fixing threaded hole being opened inside the adjustment block, sliding slots being opened on both sides inside the adjustment block, a pressure rod being slidably connected inside the sliding slots, and several extension plates installed inside the device base, with several limiting slots opened on the surface of the extension plates.

[0007] Preferably, a first return spring is fixedly connected to the rear end of the adjusting block, and the rear end of the first return spring is fixedly connected to the interior of the adjusting groove.

[0008] Preferably, a first sliding groove is provided on both sides of the inside of the adjustment groove, and a first slider is fixedly connected to both sides of the adjustment block, and the inside of the first sliding groove is slidably connected to the first slider.

[0009] Preferably, the size of the pressure rod is adapted to the inner diameter of the limiting groove.

[0010] Preferably, a second sliding groove is provided on both sides of the sliding groove, and a second slider is fixedly connected to both sides of the pressure rod, with the interior of the second sliding groove slidably connected to the second slider.

[0011] Preferably, a second return spring is slidably connected to the surface of the pressure rod, and the end of the second return spring near the adjusting block is fixedly connected to the adjusting block.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, when the staff needs to adjust the position of the cushion, the sliding rod is rotated to move out of the fixed threaded hole, releasing the pressure rod from its limit. Then, the pressure rod is pressed inward to release the adjustment block from its limit. At this point, the cushion is adjusted to a position suitable for the patient's height. Finally, the sliding rod is pushed inward and rotated into the fixed threaded hole, limiting the adjustment block and the cushion, thus achieving convenient adjustment of the cushion's front and back position. With a cushion that can be easily adjusted in front and back position, the device base can be used by patients of more different heights. This user-friendly adjustment function not only improves the efficiency of the device but also greatly increases its applicability. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figure 1 - Figure 4As shown, this utility model provides a technical solution: a decompression-type electric rehabilitation exerciser for hip and knee joints, including a device base 1, an air pump 2 installed inside the device base 1, a U-shaped contact plate 3 installed at the top of the air pump 2, a cushion 4 installed at the top of the device base 1, an electric angle adjustment mechanism 5 installed on one side of the device base 1, the cushion 4 being electrically connected to the electric angle adjustment mechanism 5, two adjustment grooves 6 opened at the top of the device base 1, an adjustment block 7 slidably connected inside the adjustment grooves 6, a sliding rod 8 slidably connected inside the adjustment block 7, a limit thread 9 opened on the surface of the sliding rod 8, a fixing threaded hole 10 opened inside the adjustment block 7, sliding grooves 11 opened on both sides inside the adjustment block 7, a pressure rod 12 slidably connected inside the sliding grooves 11, and the device base 1... The device is equipped with several extension plates 13, each with a limiting groove 14 on its surface. When the operator needs to adjust the position of the cushion 4, the sliding rod 8 is rotated out of the fixed threaded hole 10, releasing the limiting position of the pressure rod 12. The pressure rod 12 is then pressed inward to release the limiting position of the adjusting block 7. The cushion 4 is then adjusted to a position suitable for the patient's height. The sliding rod 8 is then pushed inward and rotated into the fixed threaded hole 10, limiting the adjustment block 7 and the cushion 4. This allows for convenient adjustment of the backrest 4's position. With the cushion 4's easily adjustable position, the device base 1 can be used by patients of different heights. This user-friendly adjustment function not only improves the device's efficiency but also greatly increases its applicability.

[0022] Reference Figure 2 As shown in this embodiment: the rear end of the adjusting block 7 is fixedly connected to the first return spring 15, and the rear end of the first return spring 15 is fixedly connected to the inside of the adjusting groove 6. By setting the first return spring 15, when the device base 1 is used and the cushion 4 needs to be reset, the adjusting block 7 is released from the limit. At this time, the elastic force stored in the first return spring 15 is released, which drives the cushion 4 to quickly reset to the initial position, thereby achieving the quick reset of the cushion 4 after use.

[0023] Reference Figure 4 As shown in this embodiment: a first sliding groove 16 is provided on both sides of the inside of the adjustment groove 6, and a first slider 17 is fixedly connected to both sides of the adjustment block 7. The inside of the first sliding groove 16 is slidably connected to the first slider 17. Through the setting of the first sliding groove 16 and the first slider 17, the adjustment block 7 can form a stable limit when sliding inside the adjustment groove 6, thereby effectively improving the adjustment stability of the cushion 4.

[0024] Reference Figure 3 and Figure 4As shown in this embodiment, the size of the pressure rod 12 is adapted to the inner diameter of the limiting groove 14. By adapting the size of the pressure rod 12 to the inner diameter of the limiting groove 14, the adjustment block 7 is less likely to shake or fall off when fixed, thus improving the stability of the cushion 4 after adjustment.

[0025] Reference Figure 5 As shown in this embodiment: a second sliding groove 18 is provided on both sides of the sliding groove 11, and a second slider 19 is fixedly connected to both sides of the pressure rod 12. The interior of the second sliding groove 18 is slidably connected to the second slider 19. Through the setting of the second sliding groove 18 and the second slider 19, the pressure rod 12 can form a stable guiding effect when it moves inside the sliding groove 11, preventing the pressure rod 12 from deviating during movement and causing the pressure rod 12 to fail to slide into the limiting groove 14, thereby affecting the normal fixing of the adjusting block 7.

[0026] Reference Figure 5 As shown in this embodiment: a second return spring 20 is slidably connected to the surface of the pressure rod 12. The end of the second return spring 20 near the adjustment block 7 is fixedly connected to the adjustment block 7. By setting the second return spring 20, when the cushion 4 needs to be adjusted, the sliding rod 8 is released from its limit and pulled outward, so that the pressure rod 12 is released from its limit. At this time, the elastic force stored in the second return spring 20 is released, which drives the pressure rod 12 to quickly pull back into the interior of the adjustment block 7, so that the adjustment block 7 is quickly released from its limit, thereby improving the overall operating speed.

[0027] Working principle: When the staff needs to adjust the position of the backrest 4, the sliding rod 8 is rotated to move out of the fixed threaded hole 10, releasing the pressure rod 12 from its limit. Then, the pressure rod 12 is pressed inward to release the adjusting block 7 from its limit. At this time, the backrest 4 is adjusted to a position suitable for the patient's height. After that, the sliding rod 8 is pushed inward and rotated into the fixed threaded hole 10, limiting the adjusting block 7 and the backrest 4, thus achieving convenient adjustment of the backrest 4's front and back position. The backrest 4, with its easily adjustable front and back position, allows the device base 1 to be used by patients of different heights. This user-friendly adjustment function not only improves the device's efficiency but also greatly increases its applicability. Through the first return spring 15, when the device base 1 is finished using and the backrest 4 needs to be reset, the adjusting block 7 is released, releasing the stored elasticity of the first return spring 15 and causing the backrest 4 to quickly return to its initial position, thus achieving rapid reset of the backrest 4 after use. The first slide groove 16 and the first slider 17 are designed to provide a stable limit for the adjusting block 7 when it slides inside the adjusting groove 6, thereby effectively improving the stability of the cushion 4. The size of the pressure rod 12 is matched with the inner diameter of the limiting groove 14, which makes it less likely for the adjusting block 7 to shake or fall off when it is fixed, thus improving the stability of the cushion 4 after adjustment. The second slide groove 18 and the second slider 19 are designed to provide a stable guide for the pressure rod 12 when it moves inside the sliding groove 11, preventing the pressure rod 12 from deviating during movement and failing to slide into the limiting groove 14, which would affect the normal fixation of the adjusting block 7. The second return spring 20 is designed so that when the cushion 4 needs to be adjusted, the sliding rod 8 is released from its limit and pulled outward, causing the pressure rod 12 to be released from its limit. At this time, the elastic force stored in the second return spring 20 is released, causing the pressure rod 12 to be quickly pulled back into the adjusting block 7, thus quickly releasing the limit of the adjusting block 7 and improving the overall operating speed.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
