Abstract
The utility model provides an axial positioning ball locking device of a lifesaving cabin door. The device is mainly characterized in that a hand wheel is fixed on a door shaft, and the door shaft only can rotate rather than axially moving due to a left press cover and a right press cover. The left press cover is internally embedded with an O-shaped ring, the outer circle of a door bolt is embedded with a spring cover, the door bolt is internally and axially embedded with a positioning ball, the door bolt is externally welded with a steel edge, a positioning ball press plate is connected with a shaft by a key, a pressure spring is covered on the positioning ball press plate, and the other end of the pressure spring is pressed on a spring press plate and the handle wheel. One end of a positioning bolt is fixed in the right press cover, and the other end of the positioning bolt is always arranged in a 1/8 circular opening on a baffle board. A soft steel paper washer is covered on the left press cover and is fixed between the left press cover and the door shaft by a plurality of bolts to play a part in sealing. The device has the advantages that the door bolt can be reliably driven by the positioning ball to rotate at a certain angle, so that an aim of door opening and closing is realized, the device is high in reliability and good in sealing property, the door can be opened and closed inside and outside the cabin, and the device is convenient to use.
Description
Technical field
The utility model relates to a kind of portable survival capsule, and particularly a kind of survival capsule door-hinge is to the positioning bead locking device.
Background technology
The China's coal-mine mine disaster more than 90% is outstanding, the water leak accident of gas explosion, coal-dust explosion, coal and gas.Mining packaged type survival capsule can be after the colliery has an accident, safe living space is provided for stranded survival personnel, this space requirement can completely cut off extraneous toxic and harmful and sewage.The tight mechanism structure of mining packaged type survival capsule door lock both domestic and external is simple and crude relatively at present, and sealing is poor, and the inconvenience of switch door can not effectively prevent the invasion of extraneous toxic and harmful and sewage.The positioning bead reliable transmission, processing and manufacturing is simple, and is extensive in application in machine equipments such as various moulds, automobiles.Positioning bead does not still have application in the tight mechanism of mining packaged type survival capsule door lock.
Summary of the invention
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, provides a kind of survival capsule door-hinge to the positioning bead locking device, adopts positioning bead to use in the tight mechanism of mining packaged type survival capsule door lock.Can effectively prevent the invasion of extraneous toxic and harmful and sewage.
The purpose of this utility model is achieved in that and comprises handwheel, door, taper roll bearing, alignment pin, positioning bead, positioning bead pressing plate, stage clip, key, door-hinge, spring shield, keeper, block, right gland, mild steel paper washer, left gland, O shape circle, it is characterized in that, handwheel passes through flat key, block and screw on door-hinge, stud with bearing in the door cover, by bearing, round nut, left gland, right gland door-hinge can only being rotated can not move axially.Stud with O shape circle in the gland of a left side, on door, alignment pin is fixed in the right gland by screw for left gland, right gland.Cylindrical at keeper is inlaid with spring shield, and keeper connects into an integral body by screw and block, and this integral body is threaded with door-hinge, and inner shaft is to studding with positioning bead, and it is stupefied that the outside is welded with steel, and steel is stupefied can tightly to be pressed on the lifesaving booth doorframe.The positioning bead pressing plate is connected with axle by key, and is pressed on the keeper by stage clip.Compression spring sleeve is on the positioning bead pressing plate, and the other end is pressed on spring bearer plate and the handwheel.Alignment pin one end is fixed in the right gland, and the other end is in the gap of 1/8 circle on the block all the time.The soft vulcanized fiber cushion cover, seals between left gland and door-hinge by screw on left gland.
The utility model has the advantages that, adopt positioning bead to drive keeper reliably and rotate to an angle, thereby realize switch door purpose, the reliability height, favorable sealing property, but the inside and outside all switch doors in cabin are easy to use.
Description of drawings:
Fig. 1 is a structure chart of the present utility model
The specific embodiment:
Below in conjunction with accompanying drawing present embodiment is described further:
As shown in Figure 1, handwheel 1 on door-hinge 9, studs with taper roll bearing 3 in door 2 covers by flat key 8, block 12 and screw, and by bearing 3, round nut, left gland 15, right gland 13 door-hinge 9 can only being rotated can not move axially.Stud with O shape circle 16 in the gland of a left side, on door 2, alignment pin 4 is fixed in the right gland by screw for left gland 15 and right gland 13.Cylindrical at keeper 11 is inlaid with spring shield 10, and keeper 11 connects into an integral body by screw and block 12, and this integral body is threaded with door-hinge, and inner shaft is to studding with positioning bead 5, and it is stupefied that the outside is welded with steel, and steel is stupefied can tightly to be pressed on the lifesaving booth doorframe.Positioning bead pressing plate 6 is connected with door-hinge 9 by key 8, and is pressed on the keeper 11 by stage clip 7.Stage clip 7 is enclosed within on the positioning bead pressing plate 6, and the other end is pressed on spring bearer plate and the handwheel.Alignment pin 4 one ends are fixed in the right gland, and the other end is in the gap of 1/8 circle on the block all the time.Mild steel paper washer 14 is enclosed within on the left gland on 15,, seals between left gland and door-hinge by screw.
The positioning bead head has steel ball, and there is spring inside.The positioning bead pressing plate both can rotate with door-hinge by key, can endwisely slip at the effect lower edge of stage clip pressure key again.The positioning bead pressing plate has 2 pits on the side of positioning bead, when steel ball on the positioning bead is aimed at pit, steel ball is in free state and stretches out and be absorbed in pit, handwheel drives door-hinge by key, door-hinge is by key band positioning bead pressing plate, and the positioning bead pressing plate drives keeper by positioning bead and can rotate to an angle.When axle circumferencial direction power arrived to a certain degree greatly, the positioning bead steel ball just rolled out from pit, pushes back, and slides on positioning bead pressing plate plane.The positioning bead pressing plate is tightly pushed down keeper all the time and is shifted to or away from the door direction with it.Stage clip pressure can also increase frictional force between the screw thread pair, plays locking effect.O shape circle and mild steel paper washer can effectively prevent in the immersion lifesaving booth of extraneous toxic gas and sewage.
The process of closing the door: promptly keeper changes certain angle and aims at gap on the doorframe, moves axially the process that compresses doorframe then.Drive door-hinge and the rotation of positioning bead pressing plate by rotation hand wheel, when the pit on the positioning bead pressing plate during over against last positioning bead, this moment, the steel ball on the positioning bead can drive keeper and block integral body rotates to an angle together at the active force of circumferencial direction, made keeper aim at gap on the doorframe.When alignment pin pins block, continue rotation hand wheel, block and keeper integral body can not be rotated with door-hinge, can only axially move under the guiding of alignment pin, shift to the door direction.The positioning bead pressing plate both can rotate with door-hinge by key, can endwisely slip at the effect lower edge of stage clip pressure key again.The positioning bead pressing plate tightly suppresses keeper and shifts to the door direction with it under the effect of stage clip in the process of closing the door, and rotates handwheel 3～4 circles, and keeper can compress doorframe, reaches the purpose of locking door.
The process of opening the door: the reverse rotation handwheel is opposite with the process of closing the door.
