Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of size detection, in particular to an internal taper auxiliary detection tool. Background Art
[0002] After the production of the implant is completed, it is necessary to measure various data of the implant, such as diameter, length, shape, internal taper, etc., especially the internal taper measurement is an important indicator for evaluating the contact area and contact pressure between the implant and the surrounding bone tissue, but the existing technology cannot directly measure the internal taper of the implant. When measuring, the implant must be cut open along the center line and then measured. When cutting the implant, it may cause slight deformation or damage. These slight changes may affect the measurement result of the internal taper, which leads to the need for higher processing accuracy and relatively high processing requirements. It requires high-precision processing technology and equipment to ensure it, and the product needs to be destroyed during measurement. Therefore, only some products can be sampled during production, which easily leads to the outflow of some unqualified products. In addition, cutting the implant will take a lot of time, which is not conducive to the rapid detection. Utility Model Content
[0003] In view of the deficiencies of the above-mentioned related prior arts, the present application provides an internal taper auxiliary detection tool, which can complete the internal taper detection without damaging the implant, is more convenient and quick, and has strong practicality.
[0004] In order to achieve the above purpose, the utility model adopts the following technologies:
[0005] An internal taper auxiliary detection tool comprises a support rod and a top edge block.
[0006] A nut is sleeved on the outside of the support rod, and a protrusion is provided at one end. A ring strip is provided on the outside of the protrusion along its circumferential direction, and the outer wall of the ring strip is arc-shaped; the top edge block is sleeved on the support rod and is located between the nut and the protrusion. A convex ring is also provided on the outside of the top edge block, and the outer wall of the convex ring is arc-shaped, and the outer wall diameter of the convex ring is larger than the diameter of the outer wall of the ring strip; a spring is sleeved on the support rod, and the two ends of the spring are respectively abutted against the protrusion and the top edge block, and are always in a compressed state.
[0007] Furthermore, a transition sleeve is provided on the support rod, which is located between the top edge block and the nut, and its two ends are respectively abutted against the top edge block and the nut. A thread is provided on the outer wall of the support rod, and the nut is sleeved on the thread. At least a part of the projection of the transition sleeve in the length direction coincides with the thread.
[0008] Furthermore, the cross section of the projection is trapezoidal, with the small end facing the outer end of the support rod, and the ring strip is located at the large end of the projection.
[0009] Furthermore, the convex ring is located at one end of the top edge block close to the convex block.
[0010] The beneficial effects of the utility model are as follows: by moving the top edge block, the arcs of the convex ring and the ring strip can contact the inner wall of the implant, so that the angle of the tangent edge of the arcs of the convex ring and the ring strip can be detected by an image dimension measuring instrument, and then the inner taper can be measured quickly, which is more convenient and quicker; and there is no need to damage the implant, so all products can be tested to avoid the outflow of defective products.

[0014] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.
[0015] like Figure 1-Figure 2 As shown, this example provides an internal taper auxiliary detection tool, including: a support rod 1 and a top edge block 2.
[0016] A nut 11 is sleeved on the outside of the support rod 1, and a protrusion 12 is provided at one end. A ring strip 13 is provided on the outside of the protrusion 12 along its circumferential direction, and the outer wall of the ring strip 13 is arc-shaped; the top edge block 2 is sleeved on the support rod 1 and is located between the nut 11 and the protrusion 12. A convex ring 21 is also provided on the outside of the top edge block 2. The outer wall of the convex ring 21 is arc-shaped, and the outer wall diameter of the convex ring 21 is larger than the diameter of the outer wall of the ring strip 13; a spring 4 is sleeved on the support rod 1, and the two ends of the spring 4 are respectively abutted against the protrusion 12 and the top edge block 2, and are always in a compressed state.
[0017] Specifically, a transition sleeve 3 is also provided on the support rod 1, and the transition sleeve 3 is located between the top edge block 2 and the nut 11, and the two ends are respectively abutted against the top edge block 2 and the nut 11. The outer wall of the support rod 1 is provided with a thread, and the nut 11 is sleeved on the thread. At least a part of the projection of the transition sleeve 3 in the length direction coincides with the thread, thereby ensuring that when the nut 11 is rotated, the transition sleeve 3 can always keep in contact with the nut 11, thereby ensuring that when the nut 11 is rotated, the transition sleeve 3 can always follow the movement of the nut 11.
[0018] Specifically, the cross section of the projection 12 is trapezoidal, with the small end facing the outer end of the support rod 1, and the ring strip 13 is located at the large end of the projection 12, so that the outer wall of the ring strip 13 contacts the inner wall of the implant.
[0019] Specifically, the convex ring 21 is located at one end of the top edge block 2 close to the convex block 12 to prevent the convex ring 21 from being too far away from the ring strip 13 and unable to contact the inner wall of the implant at the same time.
[0020] When in use, first loosen the nut 11, then press the support rod 1 into the implant hole, so that the ring strip 13 contacts the inner wall of the implant hole, then rotate the nut 11, press the top edge block 2 into the implant hole through the transition sleeve 3, and further compress the spring 4. Under the action of the spring 4, the top edge block 2 is always in contact with the transition sleeve 3. At this time, the outer wall of the convex ring 21 also contacts the inner wall of the implant hole, and the position of the top edge block 2 is also in a fixed state. Then, the image dimension measuring instrument can be used to detect the angle of the tangent edge between the outer wall of the convex ring 21 and the outer wall of the ring strip 13, and the inner taper of the implant hole can be measured.
[0021] Since the above are only preferred embodiments of the present invention and are not intended to limit the present invention, it is obvious that those skilled in the art can make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
