Detailed Description

As shown in figures 1-8, referring to figures 1, 2 and 4, the external bone joint fixator of the invention comprises

A housing (100) which is a cylindrical body with two open sections;

a filling part (200) having a circumferential surface fixed to an inner circumferential surface of the housing (100), an inner circumferential surface for contacting a user;

at least two massage parts 300 embedded in the filling part 200 and uniformly distributed in a circumferential direction of the filling part 200, which press a user by driving the pressing plate 313 through the multi-link structure with the slider 303 moving perpendicular to a radial direction of the housing 100, and simultaneously drive the at least two massage parts 300 to simultaneously massage through the first string 331.

In the present invention, the housing 100 and the filling part 200 are used as a supporting member for supporting the bone joints of the user, and the massage part 300 fitted into the filling part 200 is used to massage the meridians of the user, thereby promoting blood circulation at the damaged part and reducing the pain of the damaged part. Further, since at least two massage units 300 are simultaneously driven by the first cord 331, the movements thereof are almost identical, thereby preventing pain from being increased by displacement of the bone joints of the user. In addition, the simultaneous driving of the plurality of massage parts 300 by the first string 331 can avoid the inconvenience and inaccuracy of each massage part 300 requiring separate control.

Wherein, the slider 303 of the massage part 300 can be provided with a spring with the guide rail 302 between, namely, one end of the spring is fixed with the slider 303, and the other end of the spring is fixed with the guide rail 302, thereby increasing the synchronism and accuracy of each massage and avoiding the inconvenience brought by the spaciousness of the first pull rope 331 and the second pull rope 332.

Since the massage part 300 is embedded in the filling part 200, the first string 331 can be embedded in the filling part 200, thereby preventing inconvenience of the first string 331 directly acting on the skin of the human body. For example, a pipe for moving the first cord 331 is fitted and fixed in the filling portion 200.

Of course, a modification may be made such that when the diameter of the housing 100 is sufficiently small and the massage part 300 is sufficiently large, the first string 331 only moves against the inner circumferential surface of the filling part 200 without closely contacting the skin of the user, without affecting the user experience.

The filling part 200 may be a water bag, plaster or silicone sheet.

The pressing plate 313 supported by the plurality of connecting rods moves not only along the radial direction of the housing 100 but also tends to move along the radial direction, and has a component force perpendicular to the radial direction, so that the pressing plate not only acts on the meridians of the human body by a beating and pressing method, but also performs a rubbing method to a certain extent, thereby accelerating blood circulation and improving the curative effect of the massage.

Wherein the housing 100 is made of a hard material such as plastic, metal, wood; the filling part 200 is made of a hard or soft material, such as a water bag or a plaster or silicone sheet.

As a further explanation of the present invention, as shown in fig. 3, 4, 5, 6, 7, and 8, referring to fig. 3 and 5, the massage part 300 includes a support rod 301, a guide rail 302, a slider 303, a fixed link 304, a first support base 305, a first pin 306, a first link 307, a second pin 308, a second link 309, a third pin 310, a compression column 311, a fourth pin 312, a compression plate 313, a third link 314, a fifth pin 315, a fourth link 316, a sixth pin 317, and a first rope 331;

the supporting rod 301 is embedded in the filling part 200, one end of the supporting rod 301 is fixed with the casing 100, the other end of the supporting rod 301 is fixed with one end of the guide rail 302, a sliding block 303 moving along the guide rail 302 is arranged in the guide rail 302, the sliding block 303 moves along the direction perpendicular to the radial direction of the casing 100 through the guide rail 302, the other end of the guide rail 302 is fixed with one end of the fixed connecting rod 304, and the other end of the fixed connecting rod 304 is fixed with the first supporting seat 305;

a first pin 306 is fixed on the outer side surface of the slider 303, the first pin 306 is fixed with one end of the first link 307, the other end of the first link 307 is fixed with the second pin 308, the second pin 308 is mounted at one end of the second link 309 through a bearing, the other end of the second link 309 is fixed with the third pin 310, the third pin 310 is mounted at one end of the compression leg 311 close to the housing 100 through a bearing, a fourth pin 312 is mounted at the middle part of the compression leg 311 through a bearing, the lower end of the compression leg 311 is fixed with the pressing plate 313, the fourth pin 312 is fixed with one end of the third link 314, the first pin 306 is mounted at the other end of the third link 314 through a bearing, a fifth pin 315 is mounted at the middle part of the third link 314 through a bearing, and the fifth pin 315 is fixed with one end of the fourth link 316, the other end of the fourth connecting rod 316 is fixed to the sixth pin 317, and the sixth pin 317 is mounted on the first supporting seat 305 through a bearing;

at least two sliding blocks 303 of at least two massage parts 300 are connected in series to the first pulling rope 331.

The present invention drives at least two sliders 303 of at least two massage units 300 to move in a radial direction perpendicular to the housing 100 by the first rope 331, so that the at least two massage units 300 can simultaneously press the pressing plate 313 down against the skin surface of the user by the multi-link mechanism, thereby simulating the pressing technique in the massage technique. Further, since the multi-link mechanism does not simply move the pressing plate 313 in the radial direction of the housing 100 but has a component force perpendicular to the radial direction, a rubbing manipulation in a massage manipulation is simulated, thereby easily promoting blood circulation of the skin of the user, increasing the restorability of the bone joints or other bone affected parts, and enabling the user to heal as soon as possible. Further, the user is likely to feel a "tingling" feeling when the housing 100 and the filling portion 200 are fixed for a long period of time. The massage by the pressing plate 313 can also promote the blood flow to avoid the above feeling. In addition, the present invention simultaneously drives the plurality of massage parts 300 through the same first string 331 to simultaneously massage, thereby preventing the bone joints from being bent and generating only the extrusion force, and preventing the bone joints from being pulled due to the excessive movement of the bone joints.

Among the at least two sliders 303 of the at least two massage parts 300 connected in series to the first string 331, the number of the massage parts 300 and the corresponding sliders 303 may be: 2. 3, 4, 5, 6, 7, 8, 9, 10 or more.

The greater the number of the massage parts 300, the more easily the first string 331 is in a tightened state to be closely attached to the filling part 200 rather than the skin of the user.

The first cord 331 is always in a tensioned state.

The first pulling rope 331 may be connected to the filling part 200 or the housing 100 by a spring so that the slider 303 maintains a relatively stable initial position.

Wherein, the filling part 200 is provided with a working groove 210, and the working groove 210 is used for placing the massage part 300.

A first pin 306 is fixed on the outer side surface of the sliding block 303, the first pin 306 is fixed to one end of the first connecting rod 307, and of course, the first connecting rod 307 may be directly fixed to the outer side surface of the sliding block 303.

Of course, the first pin 306 may be mounted on the outer side surface of the sliding block 303 through a bearing

As a further explanation of the present invention, referring to fig. 3 and 4, at least two working grooves 210 are uniformly distributed on the inner circumferential surface of the filling part 200 along the circumferential direction, and the working grooves 210 are used for accommodating the massage part 300.

The present invention receives the massage part 300 through the working groove 210 so that the inner circumferential surface of the filling part 200 is smooth and flat enough not to allow the user's skin to touch other parts of the massage part 300 except the pressing plate 313.

As a further explanation of the present invention, the filling part 200 is a water bag or a plaster sheet or a silicone sheet.

The present invention can support the bone joint with sufficient comfort and sufficient supporting force to the skin by the filling part 200 made of the water bag, the plaster sheet or the silicone sheet. Wherein, if the filling part 200 is provided with the water bag, the water bag can be supported more comfortably.

And, if the filling part 200 is a water bag, the supporting rod 301 inserted therein should pass through the water bag and be hermetically connected to the junction of the water bag.

And, if the filling part 200 is a water bag, its surface should be rubber or silica gel or latex or nitrile rubber.

Moreover, if the filling portion 200 is a water bag, a heating device is disposed in the water bag, wherein the heating device is a conventional heating device, and is not described herein.

As a further explanation of the present invention, referring to fig. 3 and 4, when the filling part 200 is a water bag, the filling part 200 includes an inner circumferential surface, a side surface 211 of the working groove 210, a bottom surface 212 of the working groove 210, and a massage surface 213, the inner circumferential surface and the side surface 211 of the working groove 210 are made of the same hard material, the bottom surface 212 of the working groove 210 and the massage surface 213 are made of the same soft material, wherein the bottom surface 212 of the working groove 210 can contact with one end of the compression column 311 near the housing 100.

When the pressing column 311 is pressed against the bottom surface 212 of the working groove 210 made of soft material, the soft material is deformed, and the hard material is hardly deformed. Then, the massage surface 213 of the soft material protrudes toward the axis of the housing 100 to massage the skin of the user, so that the user is repeatedly massaged regardless of whether the pressing plate 313 is close to the housing 100 or far from the housing 100, thereby further exerting the kinetic energy of the multi-link structure to massage the user.

The hard material comprises: metal, thick silica gel, nitrile rubber, plastic or gypsum; the soft material comprises: thin rubber, thin latex, thin silicone. The above-mentioned thickness is all relative, and thick thickness is greater than thin can realize technical effect. For example, the hard material is preferably plastic for cola bottles, while the soft material is selected to be the same rubber or latex material as the condom. Wherein the thickness is the same as in the above example. The deformation of the hard material after being pressed is less than that of the soft material. Therefore, when the pressing column 311 abuts against the bottom surface 212 of the working tank 210 made of a soft material, the soft material is deformed, and the hard material is hardly deformed. Then, the massage face 213 of the soft material is protruded toward the axis of the housing 100, thereby massaging the skin of the user.

Wherein the massage surface 213 can be disposed between the two working grooves 210, and the area of the massage surface is not more than the bottom surface 212 of the working groove 210.

For further explanation of the present invention, referring to fig. 3 and 4, the massage surface 213 is disposed between the two working grooves 210, and the massage surface 213 has an area equal to or smaller than the bottom surface 212 of the working groove 210.

The present invention can increase the deformation amount of the massage surface 213 and increase the massage feeling by the above arrangement.

As a further explanation of the present invention, referring to fig. 3 and 4, the massage part 300 further includes a motor frame 341, a motor 342, an output shaft 343, a rope pulley 344, and a second rope 332;
