Line direction is free to slide；
The measurement auxiliary body includes the upper limit set that top is connect with connector sleeve, and connect down with upper limit set bottom end
Limit sleeve, upper limit set lower part outer wall outwardly protrude to form reference platform；Air plug gauge protrudes into upper limit set and lower limit set,
And lower limit set is stretched out in bottom end, spring pocket is set to outside air plug gauge, and it is internal to be placed in upper limit set.
Display screen and zero-setting button are provided in the digital display portion.
The upper limit set inner wall upper and lower side is respectively formed convex edge.
The internal diameter of the convex edge is less than the maximum outside diameter of spring.
The lower limit set outer diameter is greater than acetabular outer cup bottom centre, aperture, hole.
The air plug gauge outer diameter is less than acetabular outer cup bottom centre, aperture, hole.
The beneficial effects of the present invention are:
The present invention provides a kind of acetabular outer cup depth measurement device, the setting of reference platform guarantees accurate measurement acetabular outer cup
Depth, easy to use, measurement accuracy is high.

Specific embodiment
With reference to the accompanying drawings of the specification and acetabular outer cup depth measurement device of the present invention is described in detail in embodiment:
As shown in Fig. 1 ~ 3, a kind of acetabular outer cup depth measurement device, including digital display measuring mechanism 1 and measurement auxiliary body 2, institute
Stating digital display measuring mechanism 1 includes that sequentially connected digital display portion 11, axle sleeve 12 and connector sleeve 13, air plug gauge 14 accommodate from top to bottom
In in axle sleeve 12 and connector sleeve 13, and it is free to slide in the axial direction；
The measurement auxiliary body 2 includes the upper limit set 21 that top is connect with connector sleeve 13, and covers 21 bottom ends with upper limit
The lower limit set 22 of connection, upper limit cover 21 lower part outer walls and outwardly protrude to form reference platform 23；Air plug gauge 14 protrudes into the upper limit
In position set 21 and lower limit set 22, and lower limit set 22 is stretched out in bottom end, and spring 24 is sheathed on outside air plug gauge 14, and is placed in
Inside limit sleeve 21.
Display screen 15 and zero-setting button 16 are provided in the digital display portion 11.
The upper limit covers 21 inner wall upper and lower sides and is respectively formed convex edge 25.
The internal diameter of the convex edge 25 is less than the maximum outside diameter of spring 24.
The lower limit covers 22 outer diameters and is greater than 3 bottom centre hole of acetabular outer cup, 31 aperture.
14 outer diameter of air plug gauge is less than 3 bottom centre hole of acetabular outer cup, 31 aperture.
1 structural principle of digital display measuring mechanism is similar to dial gauge structural principle in the present invention.
