[0002] The rotational protection structure of an optical encoder is a key design element, designed to protect the encoder from damage caused by dust, dirt, and other external factors, while ensuring the encoder's accuracy and stability.

[0003] Existing technology discloses a rotation protection device for a photoelectric encoder and a code disk for a photoelectric encoder (CN201710563325.4), relating to the field of photoelectric equipment. The photoelectric encoder rotation protection device includes a support assembly, a rotating assembly, and a housing assembly. The support assembly is fixed to the top or side wall of the equipment, and the rotating assembly is connected to the bottom of the support assembly. The support assembly drives the housing assembly to rotate via the rotating assembly. The design of the photoelectric encoder code disk includes a code disk body and the photoelectric encoder rotation protection device.

[0004] In existing technology, the code disk body is protected by a cover to prevent dust from adhering. However, the rotating parts of the photoelectric encoder are usually exposed. The photoelectric encoder is easily affected by external interference during rotation. When the motor speed is high, the vibration will cause the code disk to reverse slightly, resulting in inaccurate pulse data. In addition, existing technology is not easy to disassemble and is not suitable for long-term maintenance.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0016] 1. Press the two abutments against the two second locking blocks. The second locking blocks come out from their corresponding second locking slots. Then remove the first locking block from the first locking slot to achieve quick disassembly. The protective cover helps to protect the electric encoder from external physical interference when it rotates. Secondly, it is easy to disassemble so that it can be frequently inspected and maintained.

[0017] 2. The rotation of the sleeve rod drives the rotating plate and the second toothed ring to rotate. Each tooth of the first toothed ring is triangular.

The two threaded rods 16 pass through the outer wall of the protective sleeve 2 to the inside of the second locking groove 15. Each side of the two second locking grooves 15 is threadedly connected to a threaded rod 16. One end of each threaded rod 16 is fixedly connected to one side of a stop block 17.

[0029] Press the two second locking blocks 18 to engage the first locking block 3 with the first locking slot 14. Rotate the electric encoder 1 to engage the two second locking blocks 18 with the two second locking slots 15. The electric encoder 1 is connected to the protective sleeve 2. When disassembling, rotate the two threaded rods 16 and the two abutments 17 press the two second locking blocks 18. The second locking blocks 18 come out from the corresponding second locking slots 15. Then, take the first locking block 3 out from the first locking slot 14 to achieve quick disassembly. The protective sleeve 2 is convenient to protect the electric encoder 1 from external physical interference when it rotates. Secondly, it is easy to disassemble so that it can be frequently inspected and maintained.

[0030] A rotation protection structure for an optical encoder, such as Figure 1 and Figure 2As shown, the anti-reverse structure includes a slider 7, a first toothed ring 9, a rotating plate 10, and a second toothed ring 11. The first toothed ring 9 is fixed to one side of the slider 7, and the second toothed ring 11 is fixed to the side of the rotating plate 10 opposite to the slider 7. The second toothed ring 11 meshes with the first toothed ring 9. The sleeve rod 12 is hollow inside and adapted to the rotating shaft 4. The sleeve rod 12 is located in the middle of the rotating plate 10 and is fixedly connected to the rotating plate 10. The rotating shaft 4 is sleeved with the sleeve rod 12. The anti-reverse structure also includes a fixing block 5. The slider 7 is set on the inner wall of the protective sleeve 2 and is fixedly connected to the inner wall of the protective sleeve 2.

[0032] The working principle of this utility model is as follows: Pressing the two second locking blocks 18 engages the first locking block 3 with the first locking slot 14. Rotating the electric encoder 1 causes the two second locking blocks 18 to engage with the two second locking slots 15, connecting the electric encoder 1 to the protective sleeve 2. During disassembly, rotating the two threaded rods 16 causes the two abutments 17 to press down on the two second locking blocks 18, causing the second locking blocks 18 to emerge from their corresponding second locking slots 15. Then, the first locking block 3 is removed from the first locking slot 14, achieving quick disassembly. The protective sleeve 2 effectively protects the electric encoder 1 from external physical interference during rotation and facilitates frequent disassembly. For inspection and maintenance, the rotating shaft 4 is connected to the sleeve rod 12, and the sleeve rod 12 is connected to the motor rotating shaft to test the speed. The rotation of the motor rotating shaft drives the sleeve rod 12 to rotate, which in turn drives the rotating shaft 4 to rotate. The rotation of the sleeve rod 12 drives the rotating plate 10 and the second toothed ring 11 to rotate. The individual teeth of the first toothed ring 9 are triangular. The rotation of the second toothed ring 11 will press the first toothed ring 9, which will drive the slider 7. The slider 7 will press the first spring 6. The second toothed ring 11 can only rotate in one direction on the side of the first toothed ring 9 to prevent vibration during operation from causing deviation of the photoelectric encoder rotating shaft 4 and affecting the data, thus ensuring accurate readings.
