Summary of the invention
For the technical problem that control switch foot-operated in prior art exposes, the present invention proposes a kind of ventilating cabinet of vertical foot-operated control switch.
For reaching this object, the present invention by the following technical solutions:
A kind of ventilating cabinet of vertical foot-operated control switch, on fixed panel bottom ventilating cabinet, at right angle setting two is respectively used to the foot-operated control switch controlling the rising of ventilating cabinet door and decline, wherein, foot-operated control switch comprises the upper jaw and lower jaw, the upper jaw and lower jaw pass through hinge, back-moving spring is provided with between the upper jaw and lower jaw, sensitive switch is provided with in lower jaw, lower jaw is fixed on fixed panel, the foot-operated control upper jaw rotates relative to lower jaw, the upper jaw push down or away from sensitive switch to control its on-off.
Preferably, the insulation spacer corresponding with sensitive switch position is provided with in the upper jaw.
Preferably, yielding rubber sheet is provided with in the upper jaw.
Preferably, two foot-operated control switchs are arranged in the left and right sides of fixed panel.
Based on disclosing of above technical scheme, the present invention possesses following beneficial effect:
In the present invention, on the fixed panel bottom ventilating cabinet, at right angle setting two is respectively used to the foot-operated control switch controlling the rising of ventilating cabinet door and decline; Apply external force by foot-operated to the upper jaw, the upper jaw rotates around bearing pin, when the upper jaw pushes down sensitive switch, and the junction closure of sensitive switch, circuit turn-on; When pin unclamps, external force is cancelled, and under the effect of back-moving spring, the upper jaw is away from sensitive switch and set back, and the contact of sensitive switch disconnects, circuit shut-down; Control actuator's action further by foot-operated control switch, thus achieve rising and the down maneuver of ventilating cabinet door.
Foot-operated control switch is vertically mounted on the fixed panel bottom ventilating cabinet, avoids by mistake stepping on foot-operated control switch, electric wire can be housed in the inside of ventilating cabinet simultaneously, it also avoid breakage and the fracture of electric wire; The Position Design of foot-operated control switch is ingenious, and operation is very easy, and practicality is very strong.
Accompanying drawing explanation
Fig. 1 is the partial structurtes schematic diagram of the ventilating cabinet of a kind of vertical foot-operated control switch that the present invention proposes.
Fig. 2 is the structural representation of foot-operated control switch in Fig. 1.
Fig. 3 is that in Fig. 2, foot-operated control switch is in the view under closure state.
Embodiment
See figures.1.and.2, Fig. 1 is the partial structurtes schematic diagram of the ventilating cabinet of a kind of vertical foot-operated control switch that the present invention proposes, Fig. 2 is the structural representation of foot-operated control switch in Fig. 1, and Fig. 3 is that in figure, foot-operated control switch is in the view under closure state.
As shown in Figure 1, the ventilating cabinet of the vertical foot-operated control switch that the embodiment of the present invention proposes, on fixed panel 10 bottom ventilating cabinet, at right angle setting two is respectively used to the foot-operated control switch 11,12 controlling the rising of ventilating cabinet door and decline, two foot-operated control switchs 11,12 are arranged in the left and right sides of fixed panel 10, can arrange foot-operated control switch 11 and control the rising of ventilating cabinet door, foot-operated control switch 12 controls ventilating cabinet door and declines;
As shown in Figure 2, foot-operated control switch 11,12 comprises the upper jaw 1 and lower jaw 2, and the upper jaw 1 is hinged by bearing pin 3 with lower jaw 2, and the upper jaw 1 and lower jaw 2 can rotate around bearing pin 3, be provided with back-moving spring 4, be provided with sensitive switch 5 in lower jaw 2 between the upper jaw 1 and lower jaw 2; Lower jaw 2 is fixed on fixed panel 10, and the foot-operated control upper jaw 1 rotates relative to lower jaw 2, the upper jaw 1 push down or away from sensitive switch 5 to control its on-off.
The specific works principle of foot-operated control switch 11,12 is as follows:
Apply external force by foot-operated to the upper jaw 1, the upper jaw 1 rotates around bearing pin 3, when the upper jaw 1 pushes down sensitive switch 5, as shown in Figure 3, and the junction closure of sensitive switch 5, circuit turn-on; When pin unclamps, external force is cancelled, and under the effect of back-moving spring 4, the upper jaw 1 is away from sensitive switch 5 and set back, and the contact of sensitive switch 5 disconnects, circuit shut-down; Control actuator's action further by foot-operated control switch 11,12, thus achieve rising and the down maneuver of ventilating cabinet door.
In operation, when operator presses switch 11 with foot-operated, ventilating cabinet door rises continuously, unclamp foot-operated by after switch 11, ventilating cabinet door stops rising, when operator presses switch 12 with foot-operated, ventilating cabinet door declines continuously, unclamps foot-operated by after switch 12, and ventilating cabinet door stops declining.
It should be noted that, in the present embodiment, foot-operated control switch 11,12 is vertically mounted on the fixed panel 10 bottom ventilating cabinet, the definition of " at right angle setting " is herein: owing to being vertically arranged between fixed panel 10 and ground, foot-operated control switch 11,12 is arranged on fixed panel, like this, in its natural state, the upper jaw 1 and the fixed panel 10 of foot-operated control switch 11,12 are in same plane, namely the upper jaw 1 of foot-operated control switch 11,12 is also arranged vertically with ground, so adopt " at right angle setting " to be described.
In a preferred embodiment, in the upper jaw 1, be provided with the insulation spacer 6 corresponding with sensitive switch 5 position, play insulating effect when the upper jaw 1 is conflicted with sensitive switch 5.
In a preferred embodiment, in the upper jaw 1, be provided with yielding rubber sheet 7, when closing up between the upper jaw 1 and lower jaw 2, prevent the upper jaw 1 from clashing into lower jaw 2 and send collision sound, eliminate the noise in switching process.
In above-described embodiment, foot-operated control switch is vertically mounted on the fixed panel bottom ventilating cabinet, avoids by mistake stepping on foot-operated control switch, electric wire can be housed in the inside of ventilating cabinet simultaneously, it also avoid breakage and the fracture of electric wire; The Position Design of foot-operated control switch is ingenious, and operation is very easy, and practicality is very strong.
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
