Detailed Description

The utility model is described in detail below with reference to the figures and the specific embodiments.

As shown in fig. 1 to 4, a groove type thread depth gauge comprises a through end shaft 1, a handle 2, a stop end shaft 3, an inner ring 4, a sliding sleeve 5, a spacer 6, a nut 7, two bearings 8 and a retainer ring 11, wherein two ends of the through end shaft 1 respectively penetrate through the two bearings 8, the two bearings 8 are arranged in the inner ring 4, outer walls of the two bearings 8 are attached to an inner wall of the inner ring 4, the through end shaft 1 is provided with a first shoulder 9 and a second shoulder 10, the nut 7 and the retainer ring 11 are both arranged between the inner ring 4 and the second shoulder 10, the nut 7 is sleeved on the through end shaft 1 and is fixedly connected with the through end shaft 1, the retainer ring 11 is sleeved on the through end shaft 1, the retainer ring 11 is arranged between the inner ring 4 and the nut 7, two ends of the nut 7 respectively abut against the second shoulder 10 and the retainer ring 11, two ends of the inner ring 4 respectively abut against the first shoulder 9 and the retainer ring 11, lead to the dead axle 1 and end axle 3 and set up respectively at the both ends of handle 2, lead to one end and handle 2 fixed connection that the dead axle 1 is close to nut 7, be provided with the external screw thread on the 3 outer walls of dead axle, be provided with the internal thread on the 2 inner walls of handle, end axle 3 and handle 2 threaded connection, the 5 covers of sliding sleeve are established on inner circle 4, sliding sleeve 5 is the tubulose, and 5 side inner walls of sliding sleeve become the plane wall to the evagination of axis direction, inner circle 4 is the tubulose, and 4 side outer walls of inner circle form the plane wall to axial direction indent, be provided with vice vernier scale reading on the inner circle 4, set up the visual window that is used for looking over inner circle 4 on the sliding sleeve 5, one side of visual window is provided with the main scale reading. The sliding sleeve 5 and the inner ring 4 can generate relative displacement in the axial direction, and the sliding sleeve 5 and the inner ring 4 can not generate relative displacement in the circumferential direction.
