Technical Field

[0001] The utility model belongs to the technical field of thread ring gauges, in particular to a novel screw thread ring gauge. Background Art

[0002] A thread ring gauge is a special measuring tool used to measure the outer diameter of a thread. It can directly read the nominal diameter of the measured thread and determine whether it is qualified. It can be used to detect screw rods. Existing thread ring gauges are usually annular bodies with threads opened inside. When using such thread ring gauges, the user usually needs to manually rotate the thread ring gauge to align with the screw rod, which is a labor-intensive operation. Utility Model Content

[0016] The utility model is described in detail below in conjunction with the accompanying drawings. Figure 1 As shown, a novel screw thread ring gauge comprises a housing 1, a motor control key 2 is fixedly mounted on the outside of the housing 1, and a rotating seat 4 is arranged inside the housing 1.

[0017] In this embodiment, combined with the Figure 2 and attached Figure 3 As shown, the rotating seat 4 is configured as a cylinder with gear teeth on the outside, and balls 45 are embedded in the annular cavities at the upper and lower ends of the rotating seat 4. A through hole 42 is opened inside the rotating seat 4, and a connecting groove 41 is symmetrically opened inside the upper end of the rotating seat 4. A ring gauge body 3 is arranged on the upper part of the rotating seat 4, and a connecting protrusion 31 is symmetrically and integrally arranged on the lower end of the ring gauge body 3. The connecting protrusion 31 is fixedly installed in the connecting groove 41. By removing the connecting protrusion 31 from the connecting groove 41, the ring gauge body 3 can be replaced. A driving gear 43 is meshedly connected to one side of the rotating seat 4, and the driving gear 43 is transmission-connected to a motor 44, which is installed in the housing 1.

[0018] In the present embodiment, specifically, annular grooves are provided on the upper and lower inner walls of the shell 1, and the annular grooves are adapted to the distribution of the balls 45. The balls 45 are rollingly arranged in the annular grooves, and the annular grooves limit the balls 45, so that the rotating seat 4 can rotate in the shell 1 without deviation.

[0019] In this embodiment, specifically, the motor 44 is a reduction motor capable of forward and reverse rotation, and the motor 44 is electrically connected to the motor control key 2 .

[0020] How it works

[0021] In the utility model, when measuring the screw rod, the user extends the screw rod into the ring gauge body 3, and rotates the motor 44 according to the rotation direction. The motor 44 drives the rotating seat 4 to rotate through the engagement of the driving gear 43 with the rotating seat 4, thereby driving the ring gauge body 3 to rotate, saving manpower for manual rotation and being able to detect whether the screw rod passes through the ring gauge body 3.

[0022] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
