Abstract
The utility model discloses a kind of cleaning machine rotary switch, comprise housing, driving shaft, with the pedestal of conducting terminal and spiral cover, it is characterized in that: described housing is provided with axle sleeve, between axle sleeve and described driving shaft, is provided with sealing rubber ring; Described driving shaft is provided with anti-skidding convex stupefied and locking projection; Described spiral cover is connected with one end of described driving shaft, and the lower surface of spiral cover is provided with the slot adapted with driving shaft, and the sidewall of slot is provided with anti-skidding convex stupefied and lock the draw-in groove and hole that projection adapts.Rotary switch good sealing effect of the present utility model, effectively isolated external dust and water droplet enter switch internal, damage switch.
Description
Technical field
The utility model relates to a kind of switch, is specifically related to a kind of rotary switch be used on cleaning machine.
Background technology
Current cleaning machine uses common switch, has gap between switching knob and switch base, and dust-proof effect is poor, and water can flow directly into switch internal from gap, causes the potential safety hazard of mains switch both positive and negative polarity short circuit, on the other hand, and the easy slippage of existing switching knob.
Summary of the invention
The purpose of this utility model is for deficiency of the prior art, provides a kind of convenient rotary switch installed of waterproof.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of cleaning machine rotary switch, comprise housing, driving shaft, with the pedestal of conducting terminal and spiral cover, described housing be provided with axle sleeve, between axle sleeve and described driving shaft, be provided with sealing rubber ring; Described driving shaft is provided with anti-skidding convex stupefied and locking projection; Described spiral cover is connected with one end of described driving shaft, and the lower surface of spiral cover is provided with the slot adapted with driving shaft, and the sidewall of slot is provided with anti-skidding convex stupefied and lock the draw-in groove and hole that projection adapts.
Further, described driving shaft is made up of the cylindrical section of bottom and top square column section; Anti-skidding convex stupefied along its axle is provided with on a side of described square column section, be provided with locking projection with on anti-skidding convex stupefied relative another side.
Further, described sealing rubber ring is placed on the cylindrical section of driving shaft, and described sealing rubber ring is stepped construction, and the external diameter of its first half is less than the external diameter of the latter half, and the external diameter of the first half equals the internal diameter of axle sleeve, the external diameter of the latter half is greater than the internal diameter of axle sleeve.
The beneficial effects of the utility model:
(1) this uses novel rotary switch good sealing effect, and effectively isolated external dust and water droplet enter switch internal, damage switch;
(2) switch spiral cover and driving shaft are connected firmly, and avoid in use spiral cover to be separated with driving shaft.
