Description

Technical Field

[0001] This invention relates to the field of small exercise equipment technology, specifically a small exercise equipment for cardiovascular and cardiac rehabilitation. Background Technology

[0002] Miniature exercise equipment refers to small fitness equipment suitable for home use, typically used for simple exercises and physical activities. These small exercise devices can help people perform aerobic exercise, strength training, and stretching exercises, contributing to maintaining physical health and increasing muscle strength.

[0003] A small cardiovascular rehabilitation exercise device, disclosed in CN217854316U, includes a concave frame and a pull-up mechanism. The pull-up mechanism is installed on the frame wall of the concave frame and consists of a crossbar, a ring, an elastic band, and a pull frame. A set of symmetrical crossbars is provided on the frame wall of the concave frame. A ring for connecting the elastic band is welded to the other end of each crossbar. An elastic band is connected to the ring, and a pull frame is provided at the other end of the elastic band. The pull-up mechanism and concave frame allow users to exercise anytime and anywhere, facilitating real-time training.

[0004] When using the aforementioned small cardiovascular rehabilitation exercise device, simple rehabilitation work can be completed for cardiovascular patients. However, when the exercise intensity needs to be adjusted, the only way to adjust the intensity is by adjusting the length of the elastic band. After adjusting the elastic band to a certain length, the adjustment method is easily limited when it is necessary to increase the exercise intensity again, which reduces the effect of adjusting the exercise intensity of the small exercise device.

[0005] Therefore, we propose a small exercise device for cardiovascular and cardiac rehabilitation. Summary of the Invention

[0006] The purpose of this invention is to provide a small exercise device for cardiovascular and cardiac rehabilitation to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a small cardiovascular rehabilitation exercise device, comprising a main support, the main support being a hollow structure, a tubing connected to the side wall of the main support, a hollow handle connected to the other end of the tubing, a massage cylinder rotatably mounted inside the main support, the side wall of the massage cylinder being evenly provided with a plurality of protrusions, and further comprising:

[0008] A counterweight device is installed inside the massage cylinder to add cold or hot water to the inside of the massage cylinder. The counterweight device includes a connecting pipe that fits onto the port of the massage cylinder. The other end of the connecting pipe is connected to a flexible hose, and the other end of the flexible hose is connected to a screw cap. A funnel is threaded onto the side wall of the screw cap. A heat-insulating water bag is fixedly connected to the lower port of the funnel. A limiting groove is formed on the side wall of the connecting pipe. A convex ring is fixedly connected to the port of the massage cylinder. The size of the convex ring is adapted to the size of the limiting groove.

[0009] An air jet structure is provided on the surface of the main support. The air jet structure includes an air pipe connected to the main support. The side wall of the air pipe is evenly provided with a plurality of air holes.

[0010] An adjustment structure is provided on the surface of the main support for flexibly adjusting the length of the hose. The adjustment structure includes two connecting strips fixedly connected to the surface of the main support. Two slide bars are slidably connected inside each of the two connecting strips. A collar is fixedly connected to the side wall of each of the two slide bars, and the collar is located on the outside of the hose.

[0011] The aforementioned components achieve the following effects: by setting up a counterweight device, it is convenient to flexibly add counterweights to the water inside the massage tube, increasing the ways to adjust the exercise intensity, and simultaneously enabling ice or heat therapy on the back, further improving the usability of the small exercise device; by setting up a jet structure, it is convenient to disperse hot or cold air during stretching exercises, further improving the uniformity of hot or cold air distribution; by setting up an adjustment structure, it is convenient to stably adjust the length of the tubing, thus facilitating the use of the small exercise device by patients with different arm spans.

[0012] Preferably, the counterweight device further includes a limiting ring fitted on the side wall of the hose, and the side wall of the limiting ring is fixedly connected to two connecting plates, both of which are threaded with bolts.

[0013] The effect achieved by the above components is that by driving the two bolts toward each other, the hose will be squeezed between the two bolts, thus achieving the sealing of the water on both sides of the hose.

[0014] Preferably, a plurality of convex pads are evenly and fixedly connected to the inner side of the hose at the port of the massage cylinder, and the convex pads are hollow frustum-shaped structures.

[0015] The aforementioned components achieve the following effect: the hollow frustum-shaped convex pad improves the tightness of the connection between the massage cylinder and the connecting pipe, preventing water from dripping.

[0016] Preferably, the side wall of the screw cap is fixedly connected to two handles, which are used to facilitate the twisting of the screw cap.

[0017] The above components achieve the following effect: the funnel and the screw cap are connected by twisting the screw cap, and the handle facilitates the twisting of the screw cap.

[0018] Preferably, the jet structure further includes two silicone pads fixedly connected to the side wall of the grip.

[0019] The effect achieved by the above components is as follows: during the stretching aerobic exercise by holding the handle, the hand will apply pressure to the silicone pad. After the hand applies pressure to the silicone pad, the pressurized gas will be squeezed into the inner side of the hollow structure's main support through the tubing.

[0020] Preferably, the surface of the silicone pad is uniformly provided with a plurality of grooves, and the grooves are arc-shaped.

[0021] The effect achieved by the above-mentioned components is that by setting grooves, the friction of the hand grip is increased, further improving the stability of the hand grip.

[0022] Preferably, a sponge block is glued to the surface of the main support near the massage cylinder, and the air tube is located inside the sponge block.

[0023] The above-mentioned components achieve the following effect: the sponge block facilitates the absorption and heat preservation of heat radiating from the surface of the massage cylinder between the main support and the massage cylinder, and then the heat is sprayed out again through the air hole, improving the dispersion effect of hot or cold air.

[0024] Preferably, the adjustment structure further includes a lead screw, which is internally threadedly connected to the connecting bar.

[0025] The aforementioned components achieve the following effects: the lead screw rotates inside the connecting bar, thereby driving the collar; the slide bar slides inside the connecting bar, thus limiting the direction of movement of the collar.

[0026] Preferably, the lead screw and the collar are internally rotatably connected, and a rotating block is fixedly connected to the end side of the lead screw.

[0027] The effect achieved by the above components is that the rotating block facilitates the rotation of the lead screw.

[0028] Preferably, the collar has a straight groove structure, and rollers are rotatably connected to the side wall of the collar.

[0029] The aforementioned components achieve the following effects: by setting rollers, the friction between the hose and the collar is reduced during the hose pulling process, further improving the stability of the hose stretching process and the extrusion effect of the gas inside the hose.

[0030] Compared with the prior art, the beneficial effects of the present invention are:

[0031] 1. By setting up a counterweight device, this invention facilitates the flexible addition of counterweights to the water inside the massage cylinder, increases the ways to adjust the exercise intensity, and can simultaneously perform ice or heat therapy on the back, further improving the usability of the small exercise device.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Please see Figure 1-8 This invention provides a technical solution: a small cardiovascular rehabilitation exercise device, comprising a main support 1, which is a hollow structure. A tubing 2 is connected to the side wall of the main support 1, and a hollow handle 3 is connected to the other end of the tubing 2. A massage cylinder 4 is rotatably mounted inside the main support 1. Several protrusions are evenly distributed on the side wall of the massage cylinder 4. The device also includes a counterweight device 5 disposed inside the massage cylinder 4 for adding cold or hot water. The counterweight device 5 includes a connecting pipe 501 fitted onto the end of the massage cylinder 4. A flexible hose 502 is connected to the other end of the connecting pipe 501, and a screw cap 505 is connected to the other end of the flexible hose 502. A funnel 509 is threadedly connected to the side wall of the screw cap 505, and the lower end of the funnel 509 is fixed. A heat-insulating water bag 503 is connected to the side wall of the connecting pipe 501, and a limiting groove 507 is opened there. A convex ring 504 is fixedly connected to the port of the massage cylinder 4. The size of the convex ring 504 is adapted to the size of the limiting groove 507. An air jet structure 6 is set on the surface of the main support 1. The air jet structure 6 includes an air pipe 63 connected to the main support 1. Several air holes 64 are evenly opened on the side wall of the air pipe 63. An adjustment structure 7 is set on the surface of the main support 1 for flexibly adjusting the length of the hose 2. The adjustment structure 7 includes two connecting strips 71 fixedly connected to the surface of the main support 1. Two slide strips 72 are slidably connected inside the two connecting strips 71. A collar 73 is fixedly connected to the side wall of the two slide strips 72. The collar 73 is located on the outside of the hose 2. By setting up the counterweight device 5, it is convenient to flexibly add counterweights to the water inside the massage cylinder 4, increasing the ways to adjust the exercise intensity. It can also simultaneously perform ice or heat therapy on the back, further improving the usability of the small exercise device. By setting up the jet structure 6, it is convenient to disperse hot or cold air during stretching exercises, further improving the uniformity of hot or cold air distribution. By setting up the adjustment structure 7, it is convenient to stably adjust the length of the tubing 2, thus facilitating the use of the small exercise device by patients with different arm spans.

[0045] The specific configuration and function of its counterweight device 5, jet structure 6, and adjustment structure 7 will be explained below.

[0046] like Figure 1 and Figure 3-6As shown, the counterweight device 5 also includes a limiting ring 510 fitted onto the side wall of the hose 502. Two connecting plates 511 are fixedly connected to the side wall of the limiting ring 510, and bolts 512 are threaded into the interior of both connecting plates 511. By driving the two bolts 512 toward each other, the hose 502 will be flattened between the two bolts 512, thereby achieving the sealing of the water on both sides of the hose 502.

[0047] Several raised pads 508 are evenly fixedly connected to the inner side of the hose 502 at the port of the massage cylinder 4. Each raised pad 508 has a hollow frustum-shaped structure. The hollow frustum-shaped raised pads 508 improve the tightness of the connection between the massage cylinder 4 and the connecting pipe 501, preventing water spillage. Two handles 506 are fixedly connected to the side wall of the screw cap 505. The handles 506 facilitate the twisting of the screw cap 505. The funnel 509 and the screw cap 505 are connected by twisting the screw cap 505, and the handles 506 facilitate this twisting operation.

[0048] like Figure 1 and Figure 2 as well as Figure 7 As shown, the jet structure 6 also includes two silicone pads 61 fixedly connected to the side wall of the grip 3. During the stretching aerobic exercise while holding the grip 3, the hand applies pressure to the silicone pads 61. After the hand applies pressure to the silicone pads 61, the pressurized gas is squeezed into the inner side of the hollow structure's main support 1 along the tubing 2.

[0049] The surface of the silicone pad 61 is evenly provided with several grooves 65, which are arc-shaped. By setting the grooves 65, the friction of the hand grip 3 is increased, further improving the stability of the hand grip 3. A sponge block 62 is glued to the surface of the main support 1 near the massage cylinder 4, and the air tube 63 is located inside the sponge block 62. The sponge block 62 facilitates the absorption and heat preservation of heat emitted from the surface of the massage cylinder 4 between the main support 1 and the massage cylinder 4, and then the heat is sprayed out again through the air hole 64, improving the dispersion effect of hot or cold air.

[0050] like Figure 1 and Figure 8 As shown, the adjusting structure 7 also includes a lead screw 75, which is internally threadedly connected to the connecting bar 71. The lead screw 75 rotates inside the connecting bar 71, thereby driving the collar 73. The slide bar 72 slides inside the connecting bar 71, which restricts the movement direction of the collar 73.

[0051] The lead screw 75 and the collar 73 are internally rotatably connected, and a rotating block 76 is fixedly connected to the end of the lead screw 75. Rotating the rotating block 76 facilitates the rotation of the lead screw 75. The collar 73 has a straight groove structure, and a roller 74 is rotatably connected to its side wall. By setting the roller 74, the friction between the hose 2 and the collar 73 during the pulling process is reduced, further improving the stability of the hose 2 during the stretching process and the extrusion effect on the gas inside the hose 2.

[0052] Working principle: After adding cold or hot water to the insulated water bag 503 according to the patient's condition, the funnel 509 facilitates the pouring of cold or hot water into the insulated water bag 503. After adding cold or hot water to the insulated water bag 503, the funnel 509 and the screw cap 505 are connected by twisting the screw cap 505. The handle 506 facilitates the twisting of the screw cap 505. After the small exercise device is placed horizontally on the hospital bed, the person can lift the insulated water bag 503. At this time, the water can flow into the massage cylinder 4 along the hose 502 and the connecting pipe 501, thereby increasing the overall weight of the massage cylinder 4. In the counterweight operation, after adding a certain amount of aqueous solution to the inside of the massage cylinder 4, the two bolts 512 can be driven towards each other, and the hose 502 will be flattened between the two bolts 512, which can achieve the sealing of the water on both sides of the hose 502. At this time, the massage cylinder 4 can be flexibly counterweighted. The rotation between the convex ring 504 and the limiting groove 507 facilitates the normal torsion of the massage cylinder 4 in the later stage. The hollow frustum-shaped convex pad 508 improves the tightness of the connection between the massage cylinder 4 and the connecting pipe 501, and avoids water dripping. The insulated water bag 503 is placed on the ground and held by the handle 3. Stretching the tubing 2 on the back allows for aerobic exercise, while the massage cylinder 4 provides a massage effect on the back. The ability to set hot or cold water not only facilitates the weight distribution of the massage cylinder 4 but also allows for heat or cold compresses on the back. Heat helps relax muscles, promotes blood circulation, and reduces muscle spasms and stiffness, which is very beneficial for chronic back pain, muscle tension, or pain caused by arthritis. Heat can also help relieve back discomfort caused by menstrual cramps or indigestion. Cold compresses reduce inflammation and swelling, alleviating pain caused by acute injuries or inflammation, and can help those suffering from acute back pain. For patients with sprains, strains, or swelling, this device alleviates pain and discomfort. Patients can choose between hot or cold water according to their own condition, further improving the usability of the small exercise device. By setting up an insulated water bag 503, the water can be kept warm, facilitating repeated mixing of the water inside the massage cylinder 4 and the insulated water bag 503, thus prolonging the effect of using hot or cold water. By setting up a counterweight device 5, it is convenient to flexibly add counterweights to the water inside the massage cylinder 4, increasing the ways to adjust the exercise intensity. It can also simultaneously perform ice or heat therapy on the back, further improving the usability of the small exercise device.

[0053] During the stretching aerobic exercise using the hand grip 3, the hand applies pressure to the silicone pad 61. The groove 65 increases the friction of the hand grip 3, further improving its stability. After the hand applies pressure to the silicone pad 61, the pressurized gas is squeezed into the hollow structure of the main support 1 along the tubing 2, and finally ejected through the air holes 64 on the air tube 63. This facilitates the even distribution of hot or cold air to the back, further enhancing the effect of heat or cold compresses. Furthermore, during the stretching of the tubing 2, the flattened structure... After being stretched, the tubing 2 of the structure will also squeeze the gas into the inner side of the main support 1 and squeeze it out through the air hole 64 on the air pipe 63, which further improves the effect of uniform gas spraying. The sponge block 62 is set to facilitate the absorption and heat preservation of the heat emitted from the surface of the massage cylinder 4 between the main support 1 and the massage cylinder 4. Afterwards, it is sprayed out again through the air hole 64, which improves the effect of hot or cold air spraying. By setting the jet structure 6, it is convenient to blow away hot or cold air during the stretching movement, which further improves the uniformity of hot or cold air distribution.

[0054] When the tubing 2 needs to be wound up, the traditional direct winding method can easily cause the tubing 2 to become flat. When the length of the tubing 2 needs to be adjusted, the rotating block 76 can be rotated. The rotating block 76 facilitates the rotation of the lead screw 75. The rotating block 76 will drive the lead screw 75 to rotate inside the connecting bar 71, thereby driving the collar 73. The sliding strip 72 inside the connecting bar 71 restricts the movement direction of the collar 73, thereby enabling the adjustment of the length of the tubing 2 between the handle 3 and the main support 1. By setting the roller 74, the friction between the tubing 2 and the collar 73 during the pulling process is reduced, further improving the stability of the tubing 2 during the stretching process and the expulsion effect of the gas inside the tubing 2. By setting the adjustment structure 7, the stable adjustment of the length of the tubing 2 is facilitated, thus facilitating the use of the small exercise device by patients with different arm spans.
