Abstract
The invention discloses a bulk-cargo box manhole structure which comprises a manhole top plate and a manhole cover. The edge of one end of the manhole cover is connected to a hinge on the manhole top plate to be connected with the manhole top plate, wherein a limiting block is arranged on the hinge and limits an opening angle of the manhole cover. The bulk-cargo box manhole structure has the advantages that an opening angle of the manhole cover is limited to prevent the overall height of a bulk-cargo box from being too high and impacting road facilities after the manhole cover is opened, the manhole cover is opened in a horizontal rotating mode to enable the overall height of the bulk-cargo box not be increased in opening, and collision between the bulk-cargo box and the road facilities is avoided.

Above-mentioned bulk cargo box manhole structure, wherein, a pair of otic placode and the described chain connection of described manhole cover by being connected with self, described limiting stopper has two, and two described limiting stoppers are located at respectively on a pair of described otic placode, to limit the opening angle of a pair of described otic placode.
Above-mentioned bulk cargo box manhole structure, wherein, described blocking device comprises locking bar otic placode, a pair of latch hook and a pair of lock hook seat that a locking bar, a pair of and described manhole cover are connected, described locking bar passes the through hole on a pair of described locking bar otic placode, and form respectively revolute pair with a pair of described locking bar otic placode, a pair of described latch hook is connected to described locking bar two ends, a pair of described lock hook seat is connected on the described manhole top plate, and described locking bar rotates and makes a pair of described latch hook and a pair of described lock hook seat form hook even or unhook.
Above-mentioned bulk cargo box manhole structure wherein, also comprises one handle, and described handle is connected in described locking bar middle part, and described handle is in order to rotate described locking bar.
Above-mentioned bulk cargo box manhole structure wherein, also comprises an assistant locking apparatus, and described assistant locking apparatus is mainly formed by the snap close on the lockhole on the described handle and the described manhole top plate, and described snap close and described lockhole form sealed.
The invention has the beneficial effects as follows:
The restriction manhole cover angle of opening is too high to prevent that manhole cover from opening rear bulk cargo box whole height, the bump road facility, and the bulk cargo box whole height can not increase when opening manhole cover manhole cover is opened to horizontally rotate mode, has avoided the collision with road facility.
Description of drawings
Fig. 1 is a kind of bulk cargo box manhole structure's of the present invention plan structure schematic diagram;
Fig. 2 is a kind of bulk cargo box manhole structure's of the present invention side-looking structural representation;
Fig. 3 is the schematic diagram of a kind of bulk cargo box manhole structure's of the present invention side-looking structure when having horizontally rotated mode and opening.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but not as limiting to the invention.
As shown in Figure 1, a kind of bulk cargo box manhole structure of the present invention comprises manhole top plate 1 and manhole cover 2, manhole cover 2 one end margins are connected with manhole top plate 1 by the hinge 3 that is connected on the manhole top plate 1, wherein, hinge 3 is provided with limiting stopper 31, the angle of the unlatching of limiting stopper 31 restriction manhole covers 2.Opening angle by restriction manhole cover 2 is restricted the height of manhole cover 2 when accident is opened, thereby avoids manhole cover 2 bump road facilitys.The form that arranges of limiting stopper 31 can have multiple; for technical scheme of the present invention is described; adopted such as the embodiment among Fig. 1; manhole cover 2 is connected with hinge 3 by a pair of otic placode 21 that is connected with self, and limiting stopper 31 has two, and two limiting stoppers 31 are located at respectively on a pair of otic placode 21; to limit the opening angle of a pair of otic placode 21; the set-up mode of above-mentioned limiting stopper 31 only is a kind of in numerous schemes, only in order to explanation, does not therefore limit protection scope of the present invention.
On the technique scheme basis, further, as shown in Figure 3, hinge 3 can arrange a rotating shaft 32 with manhole top plate 1 junction, rotating shaft 32 makes hinge 3 integral body rotate in horizontal direction, such as the embodiment among Fig. 3, rotating shaft 32 can be arranged at the middle part of hinge 3, can certainly be arranged at arbitrary end of hinge 3.Arrange that rotating shaft 32 makes hinge 3 and the manhole cover 2 that is connected with hinge 3 can horizontally rotate, make manhole cover 2 accidents open the whole height that Shi Buhui increases bulk cargo box, thereby avoided manhole cover 2 and road facility collision.
Further, wherein, manhole cover 2 a dorsad end of hinge 3 is provided with blocking device; the effect of blocking device is to prevent that manhole cover 2 accidents from opening; the setting means of blocking device has multiple, and existing embodiment in Fig. 2 describes as example, but does not limit protection scope of the present invention with this.As shown in Figure 2, blocking device comprises a locking bar 41, a pair of locking bar otic placode 42 that is connected with manhole cover 2, a pair of latch hook 43 and a pair of lock hook seat 44, locking bar 41 passes the through hole on a pair of locking bar otic placode 42, and form respectively revolute pair with a pair of locking bar otic placode 42, a pair of latch hook 43 is connected to the two ends of locking bar 41, a pair of lock hook seat 44 is connected on the manhole top plate 1, and locking bar 41 rotates and makes a pair of latch hook 43 and a pair of lock hook seat 44 form hook even or unhook.When a pair of latch hook 43 connected with a pair of lock hook seat 44 formation hooks, manhole cover 2 was lockable, and can't open, and when a pair of latch hook 43 broke off relations with a pair of lock hook seat 44, manhole cover 2 can upwards be opened or level is outwarded winding.Also comprise one handle 45, handle 45 is connected in locking bar 41 middle parts, and handle 45 is in order to rotate locking bar 41.Handle 45 is set makes rotation locking bar 41 comparatively convenient.
Thereby for preventing the handle 45 unexpected movable blocking device losing locks that make, also an assistant locking apparatus can be set, the assistant locking apparatus Main Function is with handle 45 lockings, prevent that handle 45 is unexpected movable, the implementation method of assistant locking apparatus also has a lot, embodiment in Fig. 1 is as example, can be formed by the lockhole 46 on the handle 45 and the snap close 11 on the manhole top plate 1, groove position fixing handle 45 on the snap close 11, and form sealed with lockhole 46, utilize through hole and lockhole 46 on the snap close 11 to lock by extra lockset, perhaps by a compacting part is set, thereby make the groove height of snap close 11 dwindle pressing handle 45 it can't be deviate from from the groove of snap close 11.Certainly above embodiment only is used for explanation, does not limit protection scope of the present invention with this.
The above only is preferred embodiment of the present invention; be not so limit claim of the present invention; so the technological means that the equivalent structure that all utilizations specification sheets of the present invention and diagramatic content have been done changes or those skilled in the art habitually practise is replaced, and all is included in protection scope of the present invention.
