Embodiment 2

[0037] Embodiment 2 has a waterproof coding device with a built-in magnet disc for reference Figure 4 , Figure 5 . The main structure of embodiment 2 is basically the same as that of embodiment 1, which mainly includes a knob 10 with a magnetic conduction ring 13, a circular support seat 20, a positioning shaft 50, a magnet disk 60, an induction circuit board 70, and a circular support seat 20 and Waterproof gasket 30 between panels 40 and the like.

[0038] The difference is that embodiment 2 uses Figure 5Shown is a shaft 11' with a fastening screw. The shaft 11' with fastening screws includes a shaft 111' and a fastening screw 112' extending from one end of the shaft 111'. The shaft 11 of the knob 10 in Embodiment 1 is replaced by a shaft 11' with a fastening screw, and the fastening screw 21 for fastening the circular support seat 20 and the positioning shaft 50.

[0039] Due to the use of the shaft 11' with fastening screws, the knob 10 has been changed. The middle...

Abstract

The invention relates to a waterproof coding device having a built-in magnet disc. The waterproof coding device having the built-in magnet disc comprises the magnet disc, a turn button with a shaft, an induction circuit board, a positioning shaft, and a circular support seat, wherein an inner top face of the turn button is provided with an elastic positioning sheet, a port portion of an annular chamber at an outer wall of the turn button is provided with a magnetic guide ring, the magnet disc is mounted at a central portion of the positioning shaft, the induction circuit board is fixed at a tail portion of the positioning shaft, an outer circumferential wall of the circular support seat is provided with a positioning groove, a central portion of the circular support seat is provided with a shaft sleeve, the circular support seat is on a panel, a head portion of the positioning shaft penetrates through a mounting hole of the panel, thread connection with the positioning shaft is realized through a screw, the turn button is mounted on the support seat, the shaft is in moving matching with the shaft sleeve in the support seat, and the magnetic guide ring is attracted by a magnet of the magnet disc to realize synchronous rotation of the magnet disc and the turn button. The magnet disc is arranged in the casing panel, axial positioning of the turn button is realized through magnetic force of the magnet disc, the waterproof coding device has advantages of compact structure, waterproof performance, anti-shock performance and low cost and is especially applicable to use in a high wet environment or an easy shocking occasion.

Description

technical field [0001] The invention relates to a waterproof encoding device with a built-in magnet disk, which is used for converting angular displacement into an angular displacement pulse encoding signal. Background technique [0002] An encoder is a sensor device that converts angular displacement or linear displacement signals into encoded digital signals. It has mechanical, electromagnetic induction, photoelectric, and magnetic induction types with different structures. Has been widely used. However, due to the structure of the encoder, the encoder is not easy to seal or is not well sealed. It is not safe enough to be used in high-humidity environments, such as kitchens, bathrooms and other places. [0003] The existing encoding device is used in a vibration situation, and some knobs will rotate in a small range, which will cause the output signal of the encoding device to change, affecting the measurement and control accuracy. [0004] The permanent magnets of the e...
