The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is elaborated.Should be understood that, the specific embodiment described herein only, for description and interpretation the present invention, is not limited to the present invention.
In the present invention, in the situation that do contrary explanation, the noun of locality of use as " upper and lower " typically refer to as described in the manhole cover normal mounting to aperture during manhole upward, the upper and lower orientation on ordinary meaning.For example, when the downside of compression jam plate is the manhole cover normal mounting, the side that described compression jam plate and lid are in contact with one another.
As shown in Figures 3 to 6, the mounting structure of manhole cover provided by the invention, comprise manhole 6, lid 1, head with the fastening handle 2 of negative thread and be hinged on the compression jam plate 3 around manhole, be formed with double-screw bolt 11 on described lid 1, described fastening handle 2 is connected with described double-screw bolt 11 by negative thread, wherein, the downside of described compression jam plate 3 is formed with lug boss 32 near the pin jointed end place, under state at lid 1 in closing described manhole 6, described fastening handle 2 compresses described compression jam plate 3, makes described lug boss 32 compress described lid 1 top edge.
Above-mentioned lug boss 32 is unsuitable too small, preferably is positioned at the close pin jointed end of the downside place that compresses jam plate 3.Particularly, under the state at lid 1 in closing described manhole 6, lug boss 32 is along the circumferential extension of lid 1.In addition, the position of described lug boss 32 is preferably corresponding to the edge of manhole 6.Thereby, when fastening handle 2 compresses described compression jam plate 3, on its lug boss 32 contacts in lid 1 pressure-acting just circumferential edge with manhole 6, can effectively improve sealing effectiveness.
As shown in Figure 7 and Figure 8, mounting structure as the manhole cover of a kind of specific embodiment of the present invention, described fastening handle 2 comprises for the threaded portion 22 with described double-screw bolt 11 screws thread fit, described manhole cover also comprises pressing plate 4, this pressing plate 4 has through hole, and described double-screw bolt 11 is spirally connected through described through hole and described fastening handle 2.It should be noted that the size of above-mentioned threaded portion 22 downsides should be greater than the size of described through hole, can will compress jam plate 3 by described pressing plate 4 while with assurance, tightening fastening handle 2 fixing.Thus, under the normal mounting state, described pressing plate is between described threaded portion 22 and described compression jam plate 3, and the lug boss 32 of compression jam plate 3 downsides compresses lid 1 top edge.
In conjunction with shown in Fig. 4 to Fig. 7, be formed with the first location division 41 on the pressing plate 4 described in technique scheme, be formed with the second location division 31 coordinated with described the first location division 41 on described compression jam plate 3.In material transportation, because described the first location division 41 retrains mutually with described the second location division 31, can prevent that the threaded portion 22 that causes described fastening handle 2 due to vibrations is with respect to described double-screw bolt 11 rotations, thereby prevent the material leakage, improve safety.
Particularly, described the first location division 41 can be groove, and described the second location division 31 can be fin.As shown in Figure 5 and Figure 6, described fin can be formed on described compression jam plate 3 upsides and be the outshot along its longitudinal extension, describedly vertically for described lid 1, closes the radial direction under the state of manhole 6 at manhole cover.Accordingly, described groove is formed on the periphery of described pressing plate 4, and can mutually locate with described fin.But the invention is not restricted to this, other locate modes that described the first location division 41 and described the second location division 31 also can be known to the skilled person, as long as it belongs to above-mentioned technical conceive of the present invention, all belong to protection scope of the present invention.
In the mounting structure of above-mentioned manhole cover, described manhole cover can comprise a plurality of described compression jam plates 3, accordingly, be formed with a plurality of the first location divisions 41 on described pressing plate 4 corresponding with a plurality of described compression jam plates 3, common described pressing plate 4 is arranged on the center of described lid 1.It should be noted that, although the first location division 41 shown in Fig. 4 and compression jam plate 3 are four, this does not limit the scope of the invention.
Above-mentioned fastening handle 2 generally comprises the handle portion 21 hinged with described threaded portion 22, is convenient to tighten and dismantles fastening handle 2, thereby be fixed on manhole 6 by lid 1 or open the lid 1 on manhole 6.
As a kind of preferred implementation of the present invention, described lid 1 forms the form of medial recess, as shown in Figure 3.Thus, reduced on the one hand the weight of lid 1, be convenient to the staff and open or close manhole cover; On the other hand, reduce the height of manhole cover integral body, improved its stability.
The mounting structure of manhole cover as shown in Figure 3, manhole cover can also comprise the seal gasket 5 of the annular at the outer rim place that is arranged on lid 1, has further guaranteed the sealing of storage tank.The structure of described seal gasket 5, installation are well known to a person skilled in the art, repeat no more herein.
The mounting structure of manhole cover as shown in Figure 4, wherein lid 1 can be hinged on the edge of manhole 6.At manhole under open mode, this hinged loss that can prevent lid 1, the loss of dropping etc. and to cause due to carelessness.
More than described the mounting structure of manhole cover of the present invention, on this basis, the present invention also provides a kind of storage tank, and this storage tank comprises the mounting structure of above-mentioned manhole cover, and wherein, described manhole 6 is opened on the tank body of described storage tank.
For the ease of those skilled in the art, said structure is had to better understanding, below with reference to Fig. 3, closing process and the state of lid 1 in closing manhole 6 of the mounting structure of the manhole cover of the preferred embodiment for the present invention are described.
Below describe by reference to the accompanying drawings the preferred embodiment of the present invention in detail; but; the present invention is not limited to the detail in above-mentioned embodiment; in technical conceive scope of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.
It should be noted that in addition each the concrete technical characterictic described in the above-mentioned specific embodiment, in reconcilable situation, can be combined by any suitable mode.For fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible array modes.
In addition, between various embodiment of the present invention, also can carry out combination in any, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
