Description
Technical field
The present invention relates to explosion-proof electric apparatus accessory technical field, especially relate to a kind of explosion-proof electrical distribution box.
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 of 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, and loosening very easily voluntarily, then cause certain potential safety hazard.
Summary of the invention
The object of this invention is to provide a kind of explosion-proof electrical distribution box, it is better that it has sealing effectiveness, and door-plate and doorframe are difficult for loosening voluntarily feature.
The technical solution adopted in the present invention is: explosion-proof electrical distribution box, 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 limit, left side of the right edge of described door-plate and this right doorframe is the identical inclined plane shape in angle of inclination, simultaneously, in this casing, be fixed with motor, on the power output shaft of this motor, be fixed with worm screw, this worm screw is furnished with turbine, and this turbine is engaged with tooth bar, and this tooth bar is positioned on this door-plate.
Between the front side wall in described slideway chamber and this door-plate, be provided with sealing strip.
On the limit, left side of the right edge of described door-plate and right framework, be equipped with rubber spacer.
The advantage that the present invention has is: door-plate and doorframe are difficult for loosening voluntarily.Between the limit, left side of the right edge of the door-plate of explosion-proof electrical distribution box of the present invention and right doorframe, after extruding, the open front place of this casing is sealed.Because the right edge of door-plate and the limit, left side of right doorframe are skewed, along with the extruding of the two, seal degree increases thereupon then.Meanwhile, the power transmission between motor and tooth bar is undertaken by worm-and-wheel gear, and the latching characteristics that this worm-and-wheel gear has makes the door-plate can automatic moving, and then can not become flexible voluntarily.
Brief description of the drawings
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; 20, door-plate; 30, motor; 41, worm screw, 42, turbine, 43, tooth bar; 50, sealing strip; 60, rubber spacer.
Embodiment
Embodiment, as shown in Figure 1: explosion-proof electrical distribution box, 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 limit, left side of the right edge of this door-plate 20 and this right doorframe 12 is the identical inclined plane shape in angle of inclination.Like this, along with moving right of this door-plate 20, the seal degree between this door-plate 20 and this right doorframe 12 is larger.Meanwhile, in this casing 10, be fixed with motor 30.Certainly, this motor 30 is connected to power supply by a switch.On the power output shaft of this motor 30, be fixed with worm screw 41, this worm screw 41 is furnished with turbine 42, and this turbine 42 must be arranged in casing 10, and this turbine 42 is engaged with tooth bar 43, and this tooth bar 43 is positioned on the medial surface of this door-plate 20.That is, this motor 30 drives this worm screw 41 to rotate, and this worm screw 41 drives this turbine 42 to rotate, and this turbine 42 is stirred this tooth bar 43 makes this door-plate 20 produce mobile.Like this, the latching characteristics that this worm-and-wheel gear has, makes this door-plate 20 cannot automatic moving.
Optimize, between the front side wall in this slideway chamber 111 and this door-plate 20, be provided with sealing strip 50.Like this, make to there is good sealing between this door-plate 20 and this slideway chamber 111.
Continue to optimize, on the limit, left side of the right edge of this door-plate 20 and right framework 12, be equipped with rubber spacer 60.Like this, make the sealing effectiveness between door-plate 20 and this right framework 12 better.
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.
