Detailed Description
The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses a rotary encoder.
Referring to fig. 1 and 2, rotary encoder includes casing 1, and casing 1 includes top shell 2, shell body 3 and drain pan 4, and top shell 2, shell body 3 and the concatenation of top shell 2 are cylindricly, installs grating and circuit board in the casing 1, and the one side cover of drain pan 4 is equipped with rubber circle 5. The rubber ring 5 plays a role in protecting the bottom shell 4 so as to prevent the bottom shell 4 from being abraded due to long-time rotation under the driving of a motor; meanwhile, the rubber ring 5 also plays a role in sealing.
Referring to fig. 3, a user shaft 6 is installed on a surface of the top case 2 away from the case body 3, and the user shaft 6 has a cylindrical outer contour and a hollow interior. The locking part 7 is coaxially arranged on the outer side of the user shaft 6, the outer contour of the locking part 7 is cylindrical, the inner part of the locking part 7 is hollow, and the diameter size of the locking part 7 is larger than that of the user shaft 6. Retaining member 7 is equipped with fastening bolt 8, and retaining member 7 is equipped with the screw hole that is used for fastening bolt 8 of screwing, and bolt groove 9 has been seted up to the face that user's axle 6 and fastening bolt 8 contact.
