DETAILED DESCRIPTION
[0027] The following will be combined with the embodiments to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0028] As attached Figure 1 To Attachment Figure 4As shown: A pelvic measuring ruler, comprising a first rod body 1 and a second rod body 2, wherein the second rod body 2 is arranged at the front end of the first rod body 1, and a connecting rod 3 is rotatably arranged at the left end of the front side surface of the second rod body 2, and the front end of the connecting rod 3 is rotatably connected to the rear side surface of the second rod body 2, so that the first rod body 1 and the second rod body 2 can rotate. Subsequently, a semicircular angle ruler 4 is fixedly arranged along the outer surface of the connecting rod 3 between the first rod body 1 and the second rod body 2, and when the first rod body 1 and the second rod body 2 are rotating, the semicircular angle ruler 4 is used to measure the angle value of the two rod bodies when they are unfolded, and the change of the angle value can be used to evaluate the relevant angles of the pelvis.
[0029] like Figures 1 to 3 As shown, a second slide groove 21 is linearly provided on the front side of the second rod body 2, and the second slide groove 21 is connected to the right side of the second rod body 2, and then a second slot 22 is provided at the right end of the rear side of the second rod body 2, and the second slot 22 is connected to the right side of the second rod body 2 and the second slide groove 21. At the same time, a second rotating block 23 is provided on the inner wall of the second slide groove 21, and one end of the second rotating block 23 extends into the second slot 22, and then a second rotating rod 24 is fixedly provided on the upper end surface and the lower end surface of the second rotating block 23, and one end of the second rotating rod 24 is connected to the inner wall of the second slide groove 21 in a rotating manner, so that the second rotating block 23 can be rotated by the second rotating rod 24, and during the rotation process, the second rotating block 23 can be rotated from a horizontal state to a vertical state. Finally, a second touch rod 25 is disposed in the second slide groove 21 , and an outer surface of the second touch rod 25 is provided with an external thread. Then, the right end of the second touch rod 25 is threadedly connected to the left and right end surfaces of the second rotating block 23 .
[0030] In the above scheme, by providing a second rotating rod 24 and a second rotating block 23, the second rotating block 23 can drive the second touch rod 25 to rotate. During the rotation, the touch rod in a horizontal state can be turned to a vertical state. Then the user twists the second touch rod 25 to rotate, so that one end of the second touch rod 25 can move toward the inner end. During the movement, the second touch rod 25 can easily touch the position of the anterior superior iliac spine of the pelvis, thereby allowing the user to evaluate the inclination of the pelvis.
[0031] like Figure 3 and Figure 4As shown, a first slide groove 11 is linearly opened on the rear side surface of the first rod body 1, and the first slide groove 11 is connected with the left side surface of the first rod body 1, and then a first slot 12 is opened at the left end of the rear side surface of the first rod body 1, and the first slot 12 is connected with the left side surface of the first rod body 1 and the first slide groove 11. At the same time, a first rotating block 13 is arranged on the inner wall surface of the first slide groove 11, and one end of the first rotating block 13 extends into the first slot 12, and then a first rotating rod 14 is fixedly arranged on the upper end surface and the lower end surface of the first rotating block 13, and one end of the first rotating rod 14 is connected with the inner wall surface of the first slide groove 11 in a rotating manner, so that the first rotating block 13 can be rotated by the first rotating rod 14, and during the rotation process, the first rotating block 13 can be rotated from a horizontal state to a vertical state. Finally, a first touch rod 15 is disposed in the first slide groove 11 , and an outer surface of the first touch rod 15 is provided with an external thread. Then, the left end of the first touch rod 15 is threadedly connected to the left and right end surfaces of the first rotating block 13 .
[0032] In the above scheme, by providing the first rotating rod 14 and the first rotating block 13, the first rotating block 13 can drive the first touch rod 15 to rotate. During the rotation, the touch rod in the horizontal state can be turned to the vertical state. Then the user twists the second touch rod 25 to rotate, so that one end of the second touch rod 25 can move toward the inner end. During the movement, the second touch rod 25 can easily touch the pubic symphysis of the pelvis. When the anterior superior iliac spine and the pubic symphysis of the pelvis are respectively contacted, the angle value formed between the first touch rod 15 and the second touch rod 25 is measured. When the user is in a pelvic forward tilt, the anterior superior iliac spine (compared to the pubic symphysis) will bulge outward. At this time, when the first touch rod 15 and the second touch rod 25 are in contact with the corresponding position, an acute angle can be formed (looking from top to bottom), and the pelvis can be accurately evaluated through the acute angle.
[0033] Similarly, when the user is in a posterior pelvic tilt, the pubic symphysis (compared to the anterior superior iliac spine) will bulge outward. At this time, when the first touch rod 15 and the second touch rod 25 contact the corresponding position, an obtuse angle can be formed (looking from top to bottom), and the pelvis can be evaluated and judged through the obtuse angle.
[0034] Furthermore, in order to facilitate the limiting and locking of the first rotating block 13 and the second rotating block 23 after the turning, the upper end of the first rotating rod 14 also extends to the top of the first rod body 1, and the upper end of the second rotating rod 24 extends to the top of the second rod body 2, and external threads are provided through the outer wall surface of the extended ends of the first rotating rod 14 and the second rotating rod 24. Subsequently, the first fixing member 5 and the second fixing member 6 are respectively arranged above the top of the first rod body 1 and the second rod body 2, wherein the first fixing member 5 and the second fixing member 6 are specifically butterfly nuts, and the first fixing member 5 is threadedly connected to the extended end of the first rotating rod 14, and the second fixing member 6 is threadedly connected to the extended end of the second rotating rod 24.
[0035] In the above scheme, by providing the first fixing member 5 and the second fixing member 6, when the two groups of rotating blocks are rotated through the corresponding rotating rods, the first fixing member 5 and the second fixing member 6 can be threadedly connected to these rotating rods. During the connection process, the above two fixing members will contact the outer wall surfaces of the first rod body 1 and the second rod body 2, and after the contact, they can play a role in limiting and locking the rotating rods. Through such a design, the locking of the first rotating block 13 and the second rotating block 23 can be ensured, so that the touch rod can remain accurate and stable during measurement.
[0036] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that any technician familiar with this technical field can still modify the technical solutions recorded in the aforementioned embodiments within the technical scope disclosed in the present application, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
