[0030] See also Figures 1 to 6 , what is shown in the figure is the embodiment structure selected by the present invention, which is for illustration only, and the patent application is not limited to this structure.

[0031] like Figure 1 and Figure 2 As shown, a cervical traction device comprises a traction part 1, wherein the middle part is used to connect with the traction rope 2; a fixing part 3, connected with the traction part 1; and a connecting part 4, connected with the fixing part 3; wherein the traction part 1 is provided with a horizontally placed pointer plate 5, wherein the pointer plate 5 has a built-in horizontal pointer 51 which can deflect under the action of its own gravity, a through hole 31 is opened in the middle part of the fixing part 3, wherein the through hole 31 is used for the ear to pass through, and the part of the fixing part 3 except the through hole 31 is a hollow structure and filled with heavy objects, and there are two fixing parts 3 and two connecting parts 4, wherein the two fixing parts 3 are respectively connected to the two ends of the traction part 1, and the two connecting parts 4 are respectively connected to the two fixing parts 3, and when in use, the two connecting parts 4 are detachably connected to each other so that the traction part 1, the two fixing parts 3 and the two connecting parts 4 form a ring structure that fits around the head and the chin.

[0032] It can be understood that the end of the traction rope 2 away from the traction part 1 is connected to a pulley block and a weight is hung on it to achieve cervical traction. This is an existing mature technology and will not be explained here. Similarly, different patients can choose weights of different weights according to their physical conditions such as height and weight and the condition of their cervical spine, which is also an existing mature technology.

[0033] It should be understood that the ears are exposed through the through hole 31, so as to avoid pressing the ears or covering the ears for a long time, thereby protecting the ears. The heavy objects can be filled with water, sand and other objects with good fluidity and a certain weight, which can be easily filled or discharged, and are also conducive to filling different weights of heavy objects according to different patients, conveniently controlling the weight of the heavy objects, and also conveniently controlling the balance of the heavy objects on both sides, which is practical and convenient; and can better fit the two sides of the head, with a good sense of comfort, and there will be no hard objects constantly poking the head.

[0034] It is clear that the shape of the fixing portion 3 is not limited to Figure 2 The rectangle shown may also be a circle, an oval, or other irregular shapes as long as they can fit both sides of the head.

[0035] In this embodiment, there are various structural forms in which the pointer dial 5 is horizontally arranged on the traction part 1. It can adopt the buckle form of a watch strap, the buckle form of a belt or other detachable connection forms in the prior art to facilitate installation and disassembly, or it can adopt the structural form described below.

[0036] In some embodiments, the traction part 1 includes a left traction section 11 and a right traction section 12, the left traction section 11 and the right traction section 12 are detachably connected and connected to the traction rope 2, and the ends of the left traction section 11 and the right traction section 12 away from the traction rope 2 are respectively connected to the two fixing parts 3. The left traction section 11 and the right traction section 12 have the same structure and size, ensuring that the connection point of the left traction section 11, the right traction section 12 and the traction rope 2 is the center point of the traction part 1, so that the forces on both sides are uniform and consistent, ensuring the traction effect of the cervical vertebra.

[0037] In some embodiments, Figure 4As shown, the top of the left traction section 11 near the right traction section 12 is provided with a first groove 111 and a second groove 112 connected to each other, and the upper opening width of the first groove 111 is greater than the upper opening width of the second groove 112; the top of the right traction section 12 near the left traction section 11 is provided with a third groove 121 and a fourth groove 122 connected to each other, and the upper opening width of the fourth groove 122 is greater than the upper opening width of the third groove 121; when the left traction section 11 is connected to the right traction section 12, the second groove 112 and the third groove 121 form a fifth groove; the bottom of the pointer plate 5 is provided with a boss 52, and the boss 52 includes a first convex block 521 matching the first groove 111, a second convex block 522 matching the fourth groove 122, and a third convex block 523 matching the fifth groove. The first convex block 521, the second convex block 522 and the third convex block 523 are integral. When the left traction section 11 is connected to the right traction section 12, the first protrusion 521, the second protrusion 522 and the third protrusion 523 are respectively inserted into the first groove 111, the fourth groove 122 and the fifth groove, so that the pointer plate 5 is fixed and horizontally connected to the top of the traction part 1.

[0038] In some embodiments, the first bump 521 , the second bump 522 , and the third bump 523 are all rectangular blocks, and the first groove 111 , the second groove 112 , the third groove 121 , the fourth groove 122 , and the fifth groove are all rectangular grooves.

[0039] In some embodiments, Figure 4 , Figure 5 and Figure 6As shown, connecting plates 55 are provided on the front and rear sides of the bottom of the pointer plate 5, and first connecting holes 551 are provided on the left and right sides of the connecting plate 55. The left traction section 11 and the right traction section 12 are provided with second connecting holes 6 corresponding to the first connecting holes 551. The first connecting hole 551 and the second connecting hole 6 are jointly configured with an insert rod 7, and there are two insert rods 7. The two insert rods 7 are jointly fixedly connected with a clamping plate 8 with an arc-shaped surface, and the end of the insert rod 7 away from the clamping plate 8 is connected to a pressure plate 9 with an arc-shaped surface, and the end of the insert rod 7 away from the clamping plate 8 is provided with a thread, and the pressure plate 9 is provided with a third connecting hole 91 corresponding to the first connecting hole 551. The insertion rod 7 is sleeved with a nut 71 that is compatible with the thread. When the pointer plate 5 is connected to the traction part 1 through the boss 52, the two insertion rods 7 are inserted into the first connecting hole 551, the second connecting hole 6, the first connecting hole 551 and the third connecting hole 91 in sequence, and the nut 71 is screwed into the insertion rod 7 until the pressure plate 9 is pressed against the connecting plate 55, and the clamping plate 8 is pressed against the connecting plate 55.

[0040] On the basis of the previous embodiment, this embodiment further strengthens the connection structure between the pointer plate 5 and the traction part 1, and in this embodiment, the clamping plate 8 can be pressed against the connecting plate 55, and a certain distance is left between the clamping plate 9 and the connecting plate 55. The space between the clamping plate 9 and the connecting plate 55 can be used to connect with the traction rope 2. When the arc surface of the clamping plate 9 is pressed, it can fit the connecting plate 55 well, so that the connection structure is stable and firm; when the arc surface of the clamping plate 9 is not pressed against the connecting plate 55, the traction force of the traction rope 2 can be concentrated in the middle of the arc surface, so that the two sides of the traction part 1 are evenly stressed. Similarly, the arc surface of the clamping plate 8 can fit the connecting plate 55 well, so that the connection structure is stable and firm. Similarly, the connecting plate 55 can be provided with corresponding arc surfaces, so that the connection structure is stable and firm, such as the arc surface that fits with the traction part 1, and the arc surface that fits with the clamping plate 8 or the clamping plate 9. The contact surface between the pressing plate 9 and the nut 71 is a plane, so that the nut 71 and the insert rod 7 can be tightly matched.

[0041] In some embodiments, Figure 2 As shown, the fixing portion 3 is provided with an inlet and outlet 32, and the inlet and outlet 32 ​​is far away from the through hole 31. This arrangement is conducive to the inlet and outlet of heavy objects such as water or sand.

[0042] In some embodiments, Figure 3As shown, the pointer plate 5 comprises a housing 53, a fixed shaft 54 ​​and a horizontal pointer 51. The fixed shaft 54 ​​and the horizontal pointer 51 are both installed in the housing 53, and the horizontal pointer 51 is movably sleeved on the fixed shaft 54. By providing the housing 53, the influence of the horizontal pointer 51 on the outside is avoided.

[0043] In some embodiments, Figure 3 As shown, the horizontal pointer 51 includes a needle body 511 and a sleeve portion 512. There are two needle bodies 511, and the two needle bodies 511 are symmetrically arranged on both sides of the sleeve portion 512. The sleeve portion 512 is sleeved on the fixed shaft 54, and the inner diameter of the sleeve portion 512 is larger than the outer diameter of the fixed shaft 54, so that the needle body 511 can deflect under its own gravity. This setting ensures that once the head is deflected, the horizontal pointer 51 will inevitably deflect accordingly. The initial direction of the horizontal pointer 51 can be set to be consistent with the traction direction. Once the head is deflected, the deflection of the horizontal pointer 51 can be clearly seen, thereby discovering that the head has deflected.

[0044] In some embodiments, the housing 53 has an opening on the top. The opening facilitates adjustment of the horizontal pointer 51. In other embodiments, the housing 53 has a transparent movable cover on the top, which facilitates observation of the direction of the horizontal pointer 51 at any time while preventing the horizontal pointer 51 from being affected by the outside world.

[0045] In some embodiments, Figure 3 As shown, a weight block 513 is suspended at the end of the needle body 511 away from the sleeve connection portion 512. The arrangement of the weight block 513 further ensures that once the head is deflected, the horizontal pointer 51 will inevitably deflect accordingly.

[0046] The connecting part 4 is a component for fixing the entire device on the head, and can adopt the structural form described below, or adopt any structural form in the prior art that is suitable for the present invention.

[0047] In some embodiments, the connection part 4 is provided with a Velcro, and the two connection parts 4 are detachably connected via the Velcro.

[0048] In some other embodiments, the connecting portion 4 is provided with a plastic buckle, and the two connecting portions 4 are detachably connected via the plastic buckle.

[0049] In some other embodiments, the connecting portion 4 is provided with a magnetic fastener, and the two connecting portions 4 are detachably connected via the magnetic fastener.

[0050] In some other embodiments, the connection portion 4 is provided with a belt buckle, and the two connection portions 4 are detachably connected via the belt buckle.

[0051] In other embodiments, the connecting portion 4 is a binding strap.
