Problems solved by technology

[0002] At present, the mining explosion-proof and intrinsically safe multi-circuit combined starter used in mines generally uses the handle cam (eccentric shaft) to rotate the quick-opening device to move the door up and down or left and right for a small distance, release the clamping block limit, and the door is interlocked. After the mechanism drives the sleeve pin to break away from the door cover, pull to open the door; the main disadvantage of this method is that the hinge of the door mechanism also has extension and retraction movements in addition to rotation, and the door hinge is easy to wear and tear due to the heavy weight of the door itself. And it becomes loose, and the door falls, which makes it difficult to open the door.

Embodiment 1

[0020] Embodiment 1: as figure 1 Shown: The quick-opening device of mine explosion-proof multi-circuit combined starter consists of: drive gear 5, intermediate gear I7, intermediate gear II9, intermediate gear III11, rack I6, rack II8, rack III10, rack IV12 , composed of fixed bar 13 with a bayonet; rack I6, rack II8, rack III10, rack IV12 are respectively located in the inner periphery of the door cover, the driving gear 5 is installed on the door cover, and the driving gear 5 and the gear The rack I6 meshes, the other end of the rack I meshes with the intermediate gear I, one end of the rack II meshes with the intermediate gear I, the other end of the rack II meshes with the intermediate gear II, and one end of the rack III meshes with the intermediate gear The gear II is meshed, the other end of the rack III is meshed with the intermediate gear III, and one end of the rack IV is meshed with the intermediate gear III; the four fixing bars with bayonets are installed on the i...

Embodiment 2

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the quick-opening device of the explosion-proof multi-circuit combined starter for mining also includes a door interlock device, which consists of an interlock gear 1, an interlock rack 2, Composed of 4 interlocking pins; the door interlocking device is set above the door cover, the interlocking gear 1 and the interlocking rack 2 are meshed, the interlocking rack 2 has a chute, and the interlocking pin 4 is a horizontal pin at one end. The end sleeve is in the chute 3, and the interlock pin moves up and down by sliding in the chute 3; when it is in the interlock position, the other end of the interlock pin 4 passes through the through hole of the door body fixing bar to withstand the teeth on the door cover. Because the rack is locked and cannot move, the fixed bar of the door body overlaps with the concave-convex bayonet on the rack of the door cover to limit the position, and the door cannot ...

Abstract

The invention relates to a mechanism for controlling opening or closing of doors or windows, in particular to a rapid door-opening device of a mining flame-proofing multiloop combination starter; the rapid door-opening device comprises a driving gear, a plurality of carrier gears, a plurality of racks with bayonets on the back surfaces, and a plurality of fixing bars with bayonets; the rack is arranged at the periphery of the inner side of a door cover, the driving gear is arranged on the door cover, the driving gear is meshed with one rack, a plurality of the carrier gears are respectively meshed with a plurality of the racks in a matching way, the concave part of the bayonet on the fixing bar is correspondingly staggered with the convex part of the bayonet at the back surface of the rack. The rapid door-opening device has the beneficial effects that the device has simple structure and the concept is skillful; when the door is opened and closed, a door hinge only rotates, thereby being power-saving; in addition, as the hinge only rotates without displacement when the door is opened and closed, the wearing is small, so as to lead the hinge gap to keep to be unchanged and prevent dropping phenomenon.

Description

technical field [0001] The invention relates to a mechanism for manipulating the opening or closing of a door or window, in particular to a quick door opening device of a mine flameproof multi-circuit combined starter. Background technique [0002] At present, the mining explosion-proof and intrinsically safe multi-circuit combined starter used in mines generally uses the handle cam (eccentric shaft) to rotate the quick-opening device to move the door up and down or left and right for a small distance, release the clamping block limit, and the door is interlocked. After the mechanism drives the sleeve pin to break away from the door cover, pull to open the door; the main disadvantage of this method is that the hinge of the door mechanism also has extension and retraction movements in addition to rotation, and the door hinge is easy to wear and tear due to the heavy weight of the door itself. And produce loose, door produces drop, then makes door produce the phenomenon that i...
