In conjunction with Fig. 3, the slide block 7 of the embodiment of the present invention be angularly equidistant along latch body 4 circumference can be provided with multiple;Enclose Plate inwall is correspondingly arranged on multiple and each slide block 7 guide rail one to one.It is provided by multiple equidistant and cooperates Slide block 7 and guide rail, the stress balance of latch body 4 can be made, prevent latch body 4 from causing the phenomenons such as deformation because of unbalance stress Occur.
In conjunction with Fig. 1, Fig. 2 and Fig. 3, the coaming plate of the embodiment of the present invention can include multiple and guide rail installing rack one to one 1.2, each installing rack 1.2 is U-shaped, and it includes fixed plate 1.2a axially arranged along latch body 4 and two connecting plates 1.2b, the two ends of fixed plate 1.2a are connected with base plate 1.1 and plug housing 2 respectively, and two connecting plate 1.2b are arranged in fixing On the side that plate 1.2a is relative, two guide plate 8 correspondences of guide rail are detachably connected on two connecting plate 1.2b.
In conjunction with Fig. 3, fixed plate 1.2a of the embodiment of the present invention can be welded with one and latch towards the end face of plug housing 2 The contiguous block 11 that seat 2 profiles match, contiguous block 11 can be removably connected with plug housing 2 by screw.
It should be noted that plug housing 2 generally tubular structure, therefore, contiguous block 11 can be corresponding circulus.
It addition, the contiguous block 11 of the fixed plate 1.2a end face welding of the embodiment of the present invention can be with fixed plate 1.2a mono-a pair Should, it would however also be possible to employ the relation that a contiguous block is corresponding with all fixed plates 1.2a, the embodiment of the present invention does not limits at this.
It addition, the slide block 7 of the embodiment of the present invention, guide rail and steel ball 9 are dismountable, it is possible to directly observe it and use State, when breaking down, can pinpoint the problems intuitively, and easily change, maintenance simplicity.
In conjunction with Fig. 1, the latch body 4 of the embodiment of the present invention is towards can be removable by screw on the end face drive oil cylinder 3 Unload and be provided with an oil cylinder connecting plate 12, oil cylinder connecting plate 12 can be provided with two to driving oil cylinder 3 to extend and relative cloth The the first connection otic placode 13 put, drives the telescopic end of oil cylinder 3 to be plugged in two first and connects between otic placode 13, drive oil cylinder 3 Telescopic end is connected otic placode 13 by the first bearing pin 14 with two first and connects, to realize the telescopic end driving oil cylinder 3 with latch originally The connection of body 4.
In conjunction with Fig. 1, the base plate 1.1 of the mounting seat 1 of the embodiment of the present invention can be provided with two on the end face of plug housing 2 Individual to driving oil cylinder 3 to extend and the positioned opposite second connection otic placode 15, drive the fixing end of oil cylinder 3 can be provided with one and insert Being located at two second plugboards 16 connected between otic placode 15, plugboard 16 is connected otic placode by the second bearing pin 17 with two second 15 connect, to realize the connection of the fixing end driving oil cylinder 3 and the base plate 1.1 of mounting seat 1.
Further, the plug housing 2 of the embodiment of the present invention can be fixed on be arranged on spud leg 5 various by the way of welding On bearing part, pin hole 6 is arranged on spud leg 5.
The latch body 4 of the embodiment of the present invention away from drive oil cylinder 3 axial end portion can at least provided with one section with The curved portions that pin hole 6 internal diameter is consistent.After latch body 4 inserts pin hole 6, latch body 4 outer wall and pin hole 6 internal face Contact, it is also possible to prevent latch body 4 from rotating to a certain extent.
Fig. 4 is the theoretical contact schematic diagram of latch body and pin hole, in conjunction with Fig. 4, the embodiment of the present invention in use, when When latch body 4 and pin hole 6 theoretical contact on spud leg 5, latch body 4 central shaft overlaps with the central shaft of pin hole 6, slotting Pin body 4 does not occur any deflection, slide block 7 to be in the centre of two row steel balls 9, will not come in contact, and latch body 4 comes and goes fortune The frictional force between latch body 4 and plug housing 2 is only had during Dong.
But when actually used, due to the pin hole 6 of the interference of extraneous factor, the central axis of latch body 4 and spud leg 5 Central axis not necessarily overlap.Fig. 5 is that latch body contacts schematic diagram with the actual of pin hole, in conjunction with Fig. 5, latch body 4 When contacting with pin hole 6, in order to preferably contact, latch body 4 can occur certain rotation, after latch body 4 rotates, and slide block 7 contact with steel ball 9, when latch body 4 moves back and forth, carry out rolling friction between slide block 7 and steel ball 9.Due to slide block 7 and steel ball Finite gap between 9, serves the purpose preventing latch body 4 from unrestrictedly rotating.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and Within principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
