Description
The utility model relates to a kind of closing device of container.
General six eyelet bolts and six nuts of adopting of the manhole cover of existing container screw respectively, and vessel port is sealed, and the pretightning force of six bolts is difficult to consistent, and opening manhole cover needs the lemon pine of nut one by one, very inconvenient.Operation is wasted time and energy.
The purpose of this utility model is: a kind of technical scheme of Quick-opening manhole cover is provided, and this manhole cover is closed, is opened conveniently, and it is time saving and energy saving to operate, and sealing ring is stressed evenly, good sealing effect.
The technical solution of the utility model is: the quick opening manhole is stamped lid, shell ring and retention mechanism are formed, the hinge hypomere of retention mechanism places in the sleeve, there is coiled hair the hinge lower end, between coiled hair and antiarch cover plate backing plate is arranged, backing plate and the welding of sleeve lower end, and weld with the antiarch cover plate, hinge can rotate in sleeve, sleeve places in the centre bore of circular flat deck, with the stiffener welding, the hinge epimere has external screw thread to be connected with the internal thread of spin-block, the peripheral uniform slide block that is connected with more than 3 of spin-block, bearing pin one end places in the chute on the slide block, the other end is fixedlyed connected with drive link one end, and drive link flexibly connects with supporting otic placode upper end, fixedlys connected with lid in supporting otic placode lower end, eyelet bolt lower end and support pad seat flexibly connect, and the support pad seat is fixedlyed connected with shell ring.
Lid is welded by flat deck, antiarch cover plate and stiffener, and the periphery of lid has flange, on flange and the face that the shell ring upper surface contacts sealing ring is arranged.Stiffener places arranged radially between flat deck and the antiarch cover plate, and welds with the antiarch cover plate.
Major advantage of the present utility model is: it is more convenient to open or close manhole cover, it is time saving and energy saving to operate, drive link and sealing ring are stressed evenly, lid adopts the antiarch form, under specified jar of internal pressure state, can reduce cover sheet thickness, weight reduction, reduce the whole height of manhole cover, this structure is compact more.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1: Quick-opening manhole cover front view.
The vertical view of Fig. 2: Fig. 1.
Among the figure: 1, hinge 2, handle 3, support pad seat 4, eyelet bolt 5, hex nut 6, drive link 7, runner block 8, flat deck 9, bearing pin 9A, supporting otic placode 10, plain washer 11, cottor pin 12, pin sleeve 13, contiguous block 14, supporting otic placode 15, spin-block 16, bearing pin 17, plain washer 18, cottor pin 19, bearing pin 20, plain washer 21, cottor pin 22, bearing pin 23, plain washer 24, cottor pin 25, sleeve 26, backing plate 27, sealing ring 28, stiffener 29, antiarch cover plate 30, shell ring 31, sealing ring 32, flange 33, chute 34, coiled hair
Embodiment:
Quick-opening manhole cover (seeing Fig. 1,2) mainly contains manhole lid, shell ring and fastening transmission mechanism three parts and forms.The flat deck 8 of manhole lid, antiarch cover plate 29 and stiffener 28 and flange 32 are welded, sealing ring 31 is arranged on the flange 32, also be connected to handle 2 and supporting otic placode 9A on the manhole lid, supporting otic placode 9A flexibly connects with contiguous block 13 with bearing pin 9, plain washer 10, cottor pin 11, pin sleeve 12, and contiguous block 13 is fixedlyed connected with shell ring 30; Fastening transmission mechanism mainly contains hinge 1, spin-block 15, drive link 6, eyelet bolt 4 constitutes, the bottom of hinge 1 places in the sleeve 25, can in sleeve, rotate, there is coiled hair 34 the hinge lower end, 29 of coiled hair and antiarch cover plates have backing plate 26, backing plate 26 welds with antiarch cover plate 29 and sleeve 25 lower ends respectively, sleeve 25 places the centre bore of circular dull and stereotyped lid 8, with stiffener 28 welding, the internal thread of spin-block 15 is connected with the external screw thread on hinge 1 top, the spin-block periphery is uniform to be connected with 6 runner blocks 7, on each runner block 7 chute 33 is arranged, bearing pin 16 1 ends place in the chute 33, and this end is equipped with plain washer 17, cottor pin 18, bearing pin 16 other ends are fixedlyed connected with drive link 6 one ends, drive link 6 and supporting otic placode 14 upper ends bearing pin 19, plain washer 20, cottor pin 21 flexibly connects, and supporting otic placode 14 times is fixedlyed connected with the manhole lid; The lower end of eyelet bolt 4 flexibly connects with support pad seat 3 with bearing pin 22, plain washer 23, cottor pin 24, and the support pad seat is fixedlyed connected with shell ring 30.
