Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in fig. 1-3, the hydraulic folding hatch cover includes a cover body 2 disposed on a bulkhead 1, a hatch 11 is disposed on the bulkhead 1, the hatch 11 is covered by the cover body 2, the number of the cover bodies 2 is two, a pair of the cover bodies 2 are hinged by a hinge shaft 20, a cylinder 3 is further disposed inside the hatch 11, and the cylinder 3 pushes the hinge shaft 20 to move in a vertical direction;

the bulkhead 1 is further provided with a plurality of sliding grooves 12, sliding rods 4 are arranged in the sliding grooves 12, elastic bodies 5 are arranged at the bottoms of the pair of cover bodies 2, and the elastic bodies 5 are used for connecting the cover bodies 2 and the sliding rods 4. When needs rise, folding hatch cover, 3 actions of cylinder, with the vertical jack-up that makes progress of hinge pin, a pair of lid 2 produces the rotation around articulated shaft 20 under the action of gravity, through the reasonable setting to spout 12 length, can make lid 2 keep away from the one end of articulated shaft 20 when taking place the displacement, can drive slide bar 4 and produce the displacement, thus, can play and restrict the folding angle of lid 2, make the rotation and the displacement of lid 2 more linear, rational in infrastructure and simple, can make the folding and the resetting of lid 2 fast, and spare part is less, and be convenient for maintain, repair.

The hinge shaft 20 is suspended and located above the middle of the hatch 11. The hinge shaft reciprocates in the vertical direction, so that the pair of covers 2 can reliably cover the hatch 11, and simultaneously, after the hinge shaft moves upwards, the pair of covers 2 can generate the largest angle change to increase the opening degree of the hatch 11.

The pair of sliding grooves 12 located on both sides of the hatch 11 extend along the same horizontal direction, and the pair of sliding grooves 12 located on the same side of the hatch 11 are arranged in parallel. Through the reliable setting of the position of the sliding chute 12, the cover body 2 can be ensured to be reliably displaced under the action of the elastic body 5 and the sliding rod 4.

The bulkhead 1 is further provided with a bracket 13, and the bracket 13 is used for fixing the cylinder 3. The cylinder 3 is fixed by the bracket 13, and the cylinder 3 is ensured to be in a reliable working state.

The sliding rod 4 comprises a rod body 41 and sliding seats 42 arranged on two sides of the rod body 41, the rod body 41 is in a prism shape, and the elastomer 5 is fixedly connected with the rod body 41;

the end face of the sliding seat 42 is fixedly connected with the rod body 41, a groove 43 is annularly arranged on the outer wall of the sliding seat 42, and the groove 43 is clamped in the sliding groove 12.
