The other end of each sliding shaft and two ends of the driving shaft are respectively arranged in the two corresponding moving sheaths, wherein the two eccentric shafts are arranged inside the two corresponding incomplete slots. The fast door-opening mechanism also comprises a cantilever, wherein one end of the cantilever is connected on the wall of theexplosion-proof switch and the other end of the cantilever is provided with a sleeve; the driving shaft is arranged in a way of passing through the sleeve; a spiral lifting sheath is arranged betweenthe sleeve and the driving shaft, a penetrating pin is arranged by passing through the spiral lifting sheath and the driving shaft, the wall of the spiral lifting sheath is provided with two symmetrical lifting spiral strip holes, and two ends of the penetrating pin are arranged inside the two lifting spiral strip holes. The fast door-opening mechanism has compact structure, beautiful and elegantshape and ingenious idea, can stick the periphery of a door cover conveniently, so that a mine switch can be used under a mine more conveniently and safely.
Description
Technical field
The utility model relates to a kind of flame-proof switch quick opening mechanism, specifically, has related to a kind of flame-proof switch two-dimension translational formula quick opening mechanism.
Background technology
At present, flame-proof switch quick opening mechanism commonly used has left and right sides parallel-moving type, upper and lower translation formula, quick bolt formula etc.; Wherein, the quick opening mechanism of left and right sides parallel-moving type is to be made of sliding axle, driving shaft, movable sleeve, hinge etc.; When turning handle, thereby the eccentric shaft on the driving shaft drives the folding that sliding axle horizontal movement in movable sleeve drives door; But when the flame-proof switch volume was bigger, the span of door was also bigger, and only with about fixture block obviously be difficult to guarantee the explosion-proof performance of flame-proof switch housing.
In order to overcome above problem, people are seeking a kind of desirable technical solution always.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, thereby providing a kind of is skillfully constructed, design science, simple in structure, practical, security performance is good, reliability is high flame-proof switch is with two-dimension translational formula quick opening mechanism.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of flame-proof switch two-dimension translational formula quick opening mechanism, this mechanism comprises that an end is connected two sliding axles on the flame-proof switch door closure, two short slots that are separately positioned on two sliding axle other ends, two movable sleeves, driving shafts and is separately positioned on two eccentric shafts at driving shaft two ends, the other end of two described sliding axles and the two ends of described driving shaft are installed in respectively in two corresponding movable sleeves, wherein, two described eccentric shafts are arranged in the described short slot of two correspondences; This mechanism comprises that also an end is connected the cantilever on the flame-proof switch shell wall, the described cantilever other end is provided with sleeve pipe, described driving shaft passes described sleeve pipe setting, be provided with the spiral lifting cover between described sleeve pipe and the described driving shaft, passing described spiral lifting cover and described driving shaft is provided with and passes through pin, the jacket wall of described spiral lifting cover is provided with the elevating screws cylindrical void of two symmetries, and the described pin two ends of passing through are separately positioned in two described elevating screws cylindrical voids.
The utility model has substantive distinguishing features and progress with respect to prior art, specifically, adopts this mechanism, can spread all over fixture block around the flame-proof switch shell, has more fully guaranteed the explosion-proof performance of flame-proof switch housing; This mechanism structure compactness, elegant in appearance, be skillfully constructed, can conveniently realize being stuck around the door closure, make mining switch use more convenient and safety in the down-hole.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the outwardly deploying structural representation of described spiral lifting cover.
Embodiment
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As depicted in figs. 1 and 2, a kind of flame-proof switch two-dimension translational formula quick opening mechanism, it is characterized in that: this mechanism comprises that an end is connected two sliding axles 1 on the flame-proof switch door closure, be separately positioned on two short slots of two sliding axle 1 other ends, two movable sleeves 2, driving shaft 3 and two eccentric shafts that are separately positioned on driving shaft 3 two ends, the two ends of two described sliding axle 1 other ends and described driving shaft 3 are installed in respectively in two corresponding movable sleeves 2, wherein, two described eccentric shafts are arranged in the described short slot of two correspondences, it is characterized in that: this mechanism comprises that also an end is connected the cantilever 6 on the flame-proof switch shell wall, described cantilever 6 other ends are provided with sleeve pipe, described driving shaft passes described sleeve pipe setting, be provided with the spiral lifting cover between described sleeve pipe and the described driving shaft, passing described spiral lifting cover and described driving shaft is provided with and passes through pin 5, the jacket wall of described spiral lifting cover 4 is provided with the elevating screws cylindrical void of two symmetries, and described pin 5 two ends of passing through are separately positioned in two described elevating screws cylindrical voids.
On the door closure 8 of explosion-resistant enclosure, be welded with 2 sliding axles 1 of horizontal parallel, on the sliding axle 1 short slot is arranged, in movable sleeve 2, short slot is controlled by the eccentric shaft on the driving shaft 3; Movable sleeve 2 is installed in driving shaft 3 two ends; A cantilever 6 is equipped with in movable sleeve 2 bottoms, and cantilever 6 is contained on the door closure 8; The sleeve pipe hollow of cantilever 6 between the sleeve pipe of driving shaft 3 and cantilever 6, is installed spiral lifting cover 4, and spiral lifting cover 4 and driving shaft 3 pass through pin 5 and pass.
When opening the door, handle is by handle hub 7 rotating driveshafts 3, then driving shaft 3 moves upward, at this moment, pass through pin 5 spiral lifting up and down in the elevating screws cylindrical void of spiral lifting cover 4, it is motionless that promptly described sleeve pipe and described spiral lifting overlap, simultaneously, thereby the eccentric shaft on the driving shaft 3 drives the diagonal folding that sliding axle 1 horizontal movement in movable sleeve 2 drives door, realizes the two-dimension translational of door closure 8; When at closing time, just the opposite.
