Description
Technical field
The present invention relates to explosion-proof electric apparatus component technology field, especially relate to a kind of self-locking explosion-proof tank.
Background technology
In coal mine, inferior place must need to use explosion-proof electric apparatus, and needs configuration explosion-proof electrical distribution box.At present, common way is, between the door-plate for this distribution box, sealing gasket is set, and the casing of distribution box is implemented to sealing preferably, then reaches explosion-proof object.But most door-plates of such distribution box and the sealing effectiveness at doorframe place are not ideal enough, loosening very easily voluntarily, then cause certain potential safety hazard.And the mobile of door-plate needs by electronic control, thereby cost is higher.
Summary of the invention
The object of this invention is to provide a kind of self-locking explosion-proof tank, it is lower that it has cost, and door-plate is difficult for loosening feature.
The technical solution adopted in the present invention is: self-locking explosion-proof tank, comprise casing, the open front of this casing has left-hand door frame and right doorframe, and this left-hand door frame has the slideway chamber of right-end openings, in this slideway chamber, slide and be provided with door-plate, the outside of the right edge of described door-plate is one-body molded the left raised line extending to the right, the inside on the limit, left side of described right doorframe is one-body molded the right raised line extending left, this left raised line and this right raised line match, simultaneously, the inner side edge of this left raised line is provided with magnet, the outer side edges of this right raised line is provided with electromagnet, this electromagnet is connected to power supply by switch, and, this hall sensor that right doorframe is provided with and this magnet matches, and this hall sensor and this switch match.
The outside of described left raised line is provided with handle.
The advantage that the present invention has is: cost is lower, and door-plate is difficult for loosening.Self-locking explosion-proof tank of the present invention does not need to use the movement of driven by motor door-plate, thereby cost has obtained very big reduction.After door-plate contacts with right doorframe, by magnetic attraction, make the comparatively tight of the two combination, be equivalent to form self-locking, door-plate is difficult for loosening then.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described:
Fig. 1 is the vertical view cutaway drawing of embodiments of the invention.
In figure: 10, casing, 11, left-hand door frame, 111, slideway chamber, 12, right doorframe, 121, right raised line, 122, electromagnet; 20, door-plate, 21, left raised line, 22, magnet; 30, switch; 40, hall sensor; 50, handle.
Embodiment
Embodiment, as shown in Figure 1: self-locking explosion-proof tank, comprise casing 10, the open front of this casing 10 has left-hand door frame 11 and right doorframe 12.This left-hand door frame 11 has the slideway chamber 111 of right-end openings, and this interior slip in slideway chamber 111 is provided with door-plate 20.That is, this door-plate 20 horizontally slips in this slideway chamber 111, thereby the open front of this casing 10 is formed and opens and seal.Further say, the outside of the right edge of this door-plate 20 is one-body molded the left raised line 21 extending to the right, and the inside on the limit, left side of this right doorframe 12 is one-body molded the right raised line 121 extending left, and this left raised line 21 and this right raised line 121 match.That is, when this door-plate 20 cuts out, thereby this left raised line 21 and this right raised line 121 form sealing preferably together with alternately.Meanwhile, the inner side edge of this left raised line 21 is provided with magnet 22, and the outer side edges of this right raised line 121 is provided with electromagnet 122, and this electromagnet 122 is connected to power supply (not shown on figure) by switch 30.And, this hall sensor 40 that right doorframe 12 is provided with and this magnet 22 matches, and this hall sensor 40 matches with this switch 30.; when the distance of this magnet 22 and this hall sensor 40 is enough closely time; this hall sensor 40 senses after this magnet 22; signal is passed to this switch 30 opens this switch 30; and then after these electromagnet 122 energisings, there are magnetic and 22 attractions of this magnet, make to there is good sealing between this door-plate 20 and this right doorframe 12.
Optimize, for the ease of mobile this door-plate 20, the outside of this left raised line 21 is provided with handle 50.
The foregoing is only the preferred embodiments of the present invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present invention.
