[0028] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] like Figure 1-7 As shown, the embodiment of the present invention provides an automatic measuring device for carotid stenosis, including a neck strap 1 and a placement plate 4, wherein connecting seats 2 are fixedly installed at both ends of the neck strap 1, a mounting plate 3 is sleeved on the surface of the connecting seat 2, the placement plate 4 is located between the adjacent ends of the neck strap 1, a probe 5 is provided on the inner side of the placement plate 4, a card slot 6 is provided on the inner side of the connecting seat 2, an inclined block 7 is inserted on the inner side of the mounting plate 3, a tension spring 8 is sleeved on the surface of the inclined block 7, the top end of the mounting plate 3 is rotatably connected to a limiting plate 9, a winding rod 10 is fixedly installed on the middle section of the neck strap 1, a storage cylinder 11 is rotatably connected to the surface of the winding rod 10, a tooth block 12 is provided on the top end of the storage cylinder 11, and the storage cylinder 11 is provided with a tooth block 12. A top plate 13 is fixedly installed on the top of the winding rod 10, and a pressure sensor 14 is provided on the surface of the top plate 13. A ring plate 15 is fixedly installed on the surface of the winding rod 10, and a sliding rod 16 is fixedly installed on the bottom end of the ring plate 15. A spring A17 is sleeved on the surface of the sliding rod 16, and a tooth plate 18 is slidably connected to the surface of the sliding rod 16. A contact 19 is fixedly installed on the top of the tooth plate 18, and a connecting plate 20 is fixedly installed on the top of the tooth plate 18. The top of the connecting plate 20 is rotatably connected to a pull ring 21. A motor 22 is fixedly installed on the bottom end of the storage tube 11, and a gear A23 is fixedly installed on the output end of the motor 22. A gear B24 is fixedly installed on the bottom end of the winding rod 10.

[0030] In one embodiment, a short rod 25 is fixedly mounted on the back of the placement plate 4, with a raised plate 26 fixedly mounted on one end of the short rod 25. A fixed rod 27 is fixedly mounted on the back of the mounting plate 3. A slider 28 is slidably connected to the surface of the fixed rod 27. A spring B29 is sleeved on the surface of the fixed rod 27, and a connecting plate 30 is hingedly connected to the surface of the slider 28 via a rotating shaft. When the user wears the neckband 1, a certain buffer space is provided for the placement plate 4 and the probe 5, thereby preventing compression of blood vessels during wear and allowing the probe 5 to fit more closely to the user's neck skin, thereby improving measurement accuracy.

[0031] In one embodiment, one end of the tension spring 8 is fixedly mounted on the side of the mounting plate 3, and the other end of the tension spring 8 is fixedly mounted on the surface of the inclined block 7. As the connecting seat 2 enters, the inclined block 7 is driven by the tension spring 8 to reset itself inside the slot 6.

[0032] In one embodiment, gear A23 meshes with gear B24, and gear block 12 meshes with gear plate 18. During operation, motor 22 drives gear A23 to rotate, which in turn drives gear B24 and winding rod 10 to rotate. Rotation of winding rod 10 drives neckband 1 to rewind or unwind.

[0033] In one embodiment, one end of spring A17 is fixedly mounted on the bottom end of ring plate 15, and the other end of spring A17 is fixedly mounted on the top end of tooth plate 18. When the neckband 1 is adjusted to the desired length, the pull ring 21 is released, and the spring A17 causes tooth plate 18 to slide downward, engaging tooth block 12 below.

[0034] In one embodiment, the connecting plate 30 is hinged to the convex plate 26 via a rotating shaft. Under the action of the connecting plate 30, the slider 28 can be driven to slide along the fixed rod 27 and squeeze the spring B29, thereby obtaining a buffer space.

[0035] In one embodiment, one end of the spring B29 is fixedly mounted on the surface of the fixing rod 27, and the other end of the spring B29 is fixedly mounted on the side of the slider 28. The spring B29 can drive the probe 5 to be closely attached to the skin of the user's neck under the cooperation of the connecting plate 30.

[0036] When the present invention is working, first put the neckband 1 on the neck of the user, then insert the connecting seats 2 at both ends of the neckband 1 into the inner side of the mounting plate 3 respectively. During the insertion process, the connecting seat 2 will first contact the inclined surface of the inclined block 7, and drive the inclined block 7 to slide outward under the action of pressure while deforming the tension spring 8. Then, as the connecting seat 2 enters, the inclined block 7 will be driven to reset on the inner side of the card slot 6 under the action of the tension spring 8, and then the limiting piece 9 is rotated and made to rest on the surface of the connecting seat 2. At this time, the installation of the placement plate 4 is completed, and then the connecting seat 2 is moved to the inner side of the card slot 6. Pull the pull ring 21 upward and drive the tooth plate 18 to slide upward along the slide rod 16 through the connecting plate 20. In this process, the spring A17 will be squeezed and the tooth block 12 and the tooth plate 18 will be separated. When the tooth plate 18 rises, the contact 19 will be driven to rise and contact the pressure sensor 14, thereby driving the motor 22 to work. When the motor 22 works, the gear A23 will be driven to rotate. Under the meshing action, the gear B24 and the winding rod 10 can be driven to rotate. As the winding rod 10 rotates, the neckband 1 can be driven to be wound. When the neck strap 1 is wound or unwound, the pull ring 21 is released when the length of the neck strap 1 is adjusted to a suitable length. At this time, the tooth plate 18 can be driven to slide downward along the slide rod 16 under the action of the spring A17, thereby driving the contact 19 to separate from the pressure sensor 14. As the tooth plate 18 descends, the tooth plate 18 will eventually engage with the tooth block 12 below, thereby achieving the fixing work of the winding rod 10. When the probe 5 is in contact with the skin at the neck, the placement plate 4 can be driven to slide outward along the short rod 25 under the action of pressure, and in the process, the convex The plate 26 is displaced, and then the slider 28 can be driven to slide along the fixed rod 27 under the action of the connecting plate 30, and the spring B29 can be squeezed, so as to achieve a buffering effect. At the same time, the probe 5 can be driven to stick to the skin of the user's neck to improve the test accuracy. When removing the placement plate 4, first rotate the limit piece 9 so that it no longer presses against the connecting seat 2, and then the connecting seat 2 can be pulled out from the bottom to the top. At this time, under the action of the inclined surface and the pulling force, the inclined block 7 can be driven to slide out from the inside of the slot 6, thereby completing the disassembly work.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope of protection of the claims.
