摘要： A rapidly adjustable man-hole cover seat for sustaining the alignment of a road surface and a man-hole cover, comprises a base, an adjustable seat, a man-hole cover and a cruciform hole fixing frame, a stud block, a supporting block, etc. In a large distance adjustment, the inner rim of the adjustable seat is designed so that it may be penetrated by adjustable screws. Thus the adjustable seat may be adjusted and moved for aligning with the road surface. In another small distance adjustment, a cruciform hole fixing frames are installed on the bottom of the adjustable seat for being penetrated by screws so as to be installed on the base. Further, supporting blocks are installed for distributing the weight borne by the adjustable seat, the stud block and screws so that the man-hole cover may suffer a heavy pressure and the steadiness of the man-hole cover and road surface as cars are passing is sustain.

摘要： A quick release lock for a cover is provided. The cover may be a manhole cover for closing onto a manhole ring having a radially extended flange. The quick release lock mainly includes several angularly equal-spaced cross-shaped slots provided on the cover to communicate with through holes below them, and catch elements, push elements, and cotters in the same number as that of the cross-shaped slots. The catch element each is pivotally connected to and between two fixing plates provided at two opposite sides of each through hole. The cotter each is positioned in one cross-shaped slot and extended down into she through hole. The push element each is screwed on a bar portion of the cotter below the cover. When the cotter is depressed, the push element radially pushes the catch element outward to engage with a lower edge of the flange on the ring member and thereby firmly locks the cover to the ring member. And, when the cotter is pulled upward, the push element no longer pushes the catch element so that the latter disengages from the ring member and allows the cover to be easily removed from the ring member.

摘要翻译： 提供了一个盖子的快速释放锁。 盖可以是用于封闭到具有径向延伸的凸缘的人孔环上的人孔盖。 快速释放锁主要包括几个角度相等的十字形槽，其设置在盖上以与其下方的通孔相通，以及与十字形槽相同数量的卡扣元件，推动元件和开口。 所述止动元件各自枢转地连接到设置在每个通孔的两个相对侧的两个固定板之间和之间。 孔口各自定位在一个十字形槽中并向下延伸到她通孔中。 推动元件各自拧在盖子下方的开口的杆部分上。 当开口被压下时，推动元件向外径向推动卡扣元件，以与环形构件上的凸缘的下边缘接合，从而将盖牢固地锁定到环形构件。 而且，当把手被向上拉动时，推动元件不再推动卡扣元件，使得卡扣元件脱离环形元件，并允许盖子容易地从环形元件移除。
