Abstract
The invention discloses a push-springing independent seal door for dying boxes, comprising a box, a door body and a spring hinge which connects the box and the door body. The door body is provided with a closure circuit; the closure circuit comprises a power supply, a wire, a switch and a metal coil; the box is provided with a permanent magnet corresponding to the metal coil. According to electromagnetic effect, during closing the closure circuit in the door, the metal coil generates a magnetic field which mutually attracts the permanent magnet on the box, suction force is greater than springing force of the spring hinge, and the door closes; after the switch is pressed, the closure circuit closes, the metal coil demagnetizes, and the spring hinge springs to open the door. The push-springing independent seal door is easy to open.
Description
Technical field
The present invention relates to antecedent soil moisture field, particularly press bullet formula independence drying box hermatic door.
Background technology
Antecedent soil moisture machine is provided with drying box, the switch of the drying box hermatic door that open market uses is for rotating unlocking manner, namely chamber door is arranged rotary snap close, key Unscrew is used in outside, this unfolding mode is very common also very simple, but testing staff is present during detection, usually both hands all hold detection sample, or with the hands just to can arrest large sample disc, so just cannot open drying box door.
Summary of the invention
The object of this invention is to provide a kind of simple and convenient, only need gently press the hermatic door just automatically spread out.
For achieving the above object, the present invention adopts following technical scheme, by bullet formula independence drying box hermatic door, comprise the spring hinge of casing, chamber door and connect box and chamber door, chamber door is provided with closed circuit, closed circuit comprises power supply, wire, switch and wire coil, and power supply, switch and wire coil are by wired in series, and on casing, corresponding wire coil is provided with permanent magnet.When in chamber door, closed circuit closes, wire coil produces magnetic field, and the permanent magnet on casing attracts each other, and suction is greater than the elastic force of spring hinge, and chamber door closes, and after pressing switch, closed circuit disconnects, and wire coil demagnetization, chamber door flicks by spring hinge.
In some embodiments, wire coil is silicon steel coil or soft iron coil.Easily demagnetization after silicon steel or soft iron power-off.
In some embodiments, chamber door is stainless steel chamber door.Stainless steel chamber door is not by wire coil influence of magnetic field.
In some embodiments, casing is stainless steel casing.Stainless steel casing does not affect by permanent magnet.
In some embodiments, switch bottom is provided with spring.Spring is used for reset switch.
Beneficial effect of the present invention is: use galvanomagnetic-effect, when in chamber door, closed circuit closes, wire coil produces magnetic field, and the permanent magnet on casing attracts each other, and suction is greater than the elastic force of spring hinge, chamber door closes, after pressing switch, closed circuit disconnects, wire coil demagnetization, chamber door flicks by spring hinge, and opening the door, it is simple and easy to facilitate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, by bullet formula independence drying box hermatic door, comprise the spring hinge 3 of casing 1, chamber door 2 and connect box 1 and chamber door 2, install closed circuit in chamber door 2, closed circuit comprises power supply 5, wire 6, switch 7 and wire coil 8, and power supply 5, switch 7 and wire coil 8 are connected by wire 6, on casing 1, corresponding wire coil 8 embeds mounting permanent magnet 9, casing 1 and chamber door 2 adopt stainless steel material, and wire coil 8 adopts silicon steel, and switch 7 bottom is provided with spring 10.Spring 10 is for reset switch 7, and power supply 5 adopts 12V dc source, and producing suction after wire coil 8 is energized is 200N.
When closed circuit closes, wire coil 8 produces magnetic field, attract each other with the permanent magnet 9 on casing 1, suction is greater than the elastic force of spring hinge 3, and casing 1 and chamber door 2 close, after pressing switch 7, closed circuit disconnects, wire coil 8 demagnetization, chamber door 2 flicks by spring hinge 3, reaches automatic door opening effect.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
