Abstract
The utility model relates to a normally opening switch and an static powder-spraying gun with the normally opening switch, comprising a fixing base with a trigger switch at one side and a button with a trigger piece, the button is arranged at one side of the fixed base and can be rotated relatively to the fixed base, the trigger piece and the trigger switch are matched, homopolar magnets are respectively arranged on two opposite surfaces of the fixed base and the button, a certain distance is kept between two homopolar magnets, and the trigger switch and the trigger piece, the switch is always kept to be opened when no external force acts on the switch due to polar repulsion of two magnets of the switch, when the switch is arranged on the static powder-spraying gun and is used repeatedly, the acting force between two magnets is not changed, the switch can be reset on time, the service life of the static powder-spraying gun is prolonged, and the usage is convenient.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of magnetic normal open switch and the electrostatic dusting rifle of this switch is installed.
Background technology
At present, normal open switch comprises that a side is equipped with the holder of trigger switch and the button that triggers part is installed mostly, but button relative fixed seat rotates, triggering part and trigger switch is complementary, be provided with spring between two opposite faces of button and holder, when this switch was installed on the electrostatic dusting rifle, because spring is after reusing repeatedly, its elasticity can reduce gradually, even follow the string, be difficult to automatically reset after causing button to be pressed, trigger part and can not separate with trigger switch on time, make the electrostatic dusting rifle not stop at any time dusting, bring inconvenience to work, and spring damages easily, and service time is short.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, a kind of long service life, normal open switch easy to use is provided and the electrostatic dusting rifle of this switch is installed.
The utility model is achieved in that a kind of normal open switch, comprise that a side is equipped with the holder of trigger switch and the button that triggers part is installed, but this button is installed in a described side and the relative fixed seat of holder and rotates, described triggering part and trigger switch are complementary, be relatively set with a homopolarity magnetic patch on two opposite faces of described holder and button respectively, have certain distance between described two magnetic patch and trigger switch and the triggering part.
A kind of electrostatic dusting rifle comprises above-mentioned described normal open switch.
The utility model also has following additional technical feature:
Described trigger switch is a magnetic switch, and described triggering part is a magnet.
A kind of normal open switch that the utility model provides and the electrostatic dusting rifle that this switch is installed compared with prior art have following advantage: be relatively set with a homopolarity magnetic patch on two opposite faces of described holder and button respectively, has certain distance between described two magnetic patch and trigger switch and the triggering part, because two magnetic patch homopolar-repulsions, make switch open not having often to remain under the situation of external force, when this switch is installed on the electrostatic dusting rifle, reuse switch repeatedly after, active force between two magnetic patch can not change, switch can automatically reset on time, not only prolong the useful life of electrostatic dusting rifle, and easy to use.
Description of drawings
Fig. 1 is the structural representation of a kind of optimal way of the utility model.
Fig. 2 is the structural representation of electrostatic dusting rifle in the utility model.
Embodiment
Referring to Fig. 1, a kind of optimal way of the new a kind of normal open switch of this practicality is shown, comprise that a side is equipped with the holder 1 of trigger switch 11 and the button 2 that triggers part 21 is installed, but this button 2 is installed in a described side and the relative fixed seat 1 of holder and rotates, described triggering part 21 is complementary with trigger switch 11, be relatively set with a homopolarity magnetic patch 3 on two opposite faces of described holder 1 and button 2 respectively, has certain distance between described two magnetic patch 3 and trigger switch 11 and the triggering part 21, make that magnetic patch 3 can the interference triggered switch and trigger trigger process between the part, and, because two magnetic patch, 3 homopolar-repulsions, make this switch open not having often to remain under the situation of external force, when reuse switch repeatedly after, the active force between two magnetic patch can not change, switch can automatically reset on time, and it is easy to use, life-span is long.
In the present embodiment, described trigger switch 11 is a magnetic switch, and described triggering part 21 is a magnet, when pressing the button 2, button relative fixed seat 1 rotates, and magnet rotates with button, and near magnetic switch, under the effect in magnetic field, the magnetic switch closure, conducting the circuit at its place; When release button 2, it resets rapidly under the effect of two homopolarity magnetic patch repulsion, and magnet separates with magnetic switch, and magnetic switch place circuit disconnects.When this switch was installed on the electrostatic dusting rifle, as shown in Figure 2, button 1 rotated relative to rifle body 4 under external force, triggered part 21 near rifle body 4, and triggered the trigger switch 11 that is arranged in the rifle body, made its closure, and powder just sprays from podwer gun; Remove external force, button 2 automatically resets, and trigger switch 11 disconnects, and podwer gun quits work.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model spirit and scope; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
Claims (3)
