SUMMERY OF THE UTILITY MODEL

In view of the not enough and defect that exists among the prior art, the utility model provides a marine manhole cover, simple structure can support the manhole cover when the manhole cover is opened for solve the problem of mentioning among the background art.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a marine manhole cover, installs on the wallboard, includes the apron, the apron with the wallboard passes through bolted connection, the apron outside is equipped with two add boards of symmetry, the lower extreme rotation of add board is equipped with the supporting leg, the tip of supporting leg is equipped with the walking wheel be equipped with two tracks on the wallboard, the walking wheel can slide in the track, be equipped with the hole groove on the wallboard of outside on the track, be equipped with two handles on the apron.

As a further improvement of the utility model, the supporting leg articulates through articulated frame the lower extreme of add-on board, the supporting leg can be to keeping away from along with the rotation the direction of apron rotates, one side welding of supporting leg has vertical board, vertical board rotatory to with the wallboard is when the vertical condition with the lower terminal surface contact of add-on board for the supporting leg rotatory to with stop rotatoryly when adding the board perpendicularly.

As a further improvement of the utility model, every be equipped with two on the add-on board the supporting leg.

As a further improvement, the supporting leg is provided with two baffles, two the baffles are respectively fixed at the left and right ends of the walking wheel.

As a further improvement of the utility model, the cross section of the track is in a shape like a Chinese character 'tu' with an open upper end.

Compared with the prior art, the utility model discloses the beneficial effect who has does: the utility model discloses simple structure passes through slidable mounting with it on the wallboard, when opening and closing the manhole, need not artifical transport and just can slide the manhole cover, has made things convenient for the crew.

Detailed Description

In order to make the technical solution and the advantages of the present invention more clear and more obvious, the present invention is further described in detail with reference to the accompanying drawings and the specific embodiments, it should be understood that the specific embodiments described herein are only used for understanding the present invention, and are not used for limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the utility model relates to a marine manhole cover installs on wallboard 1, including apron 2, apron 2 passes through bolt 3 with wallboard 1 and is connected, and 2 outsides of apron are equipped with two additional plates 4 of symmetry, and the lower extreme rotation of additional plate 4 is equipped with supporting leg 7, and the tip of supporting leg 7 is equipped with walking wheel 6, is equipped with two tracks 8 on wallboard 1, and walking wheel 6 can slide in track 8, is equipped with hole groove 5 on the wallboard 1 of outside on track 8, is equipped with two handles on the apron 2. The supporting leg 7 is hinged to the lower end of the outer plate 4 through the hinge frame 10, the supporting leg 7 can rotate along with rotation in the direction away from the cover plate 2, a vertical plate 12 is welded on one side of the supporting leg 7, and the vertical plate 12 is in contact with the lower end face of the outer plate 4 when the supporting leg 7 rotates to be perpendicular to the wall plate 1, so that the supporting leg 7 stops rotating when rotating to be perpendicular to the outer plate 4. Two support legs 7 are arranged on each additional plate 4. Two baffles 11 are arranged on the supporting leg 7, and the two baffles 11 are respectively fixed at the left end and the right end of the travelling wheel 6.
