Detailed Description

For a further understanding of the present utility model, the present utility model will be described in detail with reference to the drawings and examples. It is to be understood that the examples are illustrative of the present utility model and are not intended to be limiting.

Examples

As shown in fig. 1-3, the embodiment provides a device comprising a bottom ring 110, an inner ring 120 is connected to the bottom ring 110 in a threaded manner, and a well lid 130 is integrally connected to the top end of the inner ring 120; the bottom of the bottom ring 110 is provided with an annular gap 112, a rotatable swivel 150 is arranged in the gap 112, the bottom end of the bottom ring 110 is connected with a plurality of stop blocks 140, and the stop blocks 140 can stop the swivel 150 in the gap 112; a plurality of mounting holes 151 are formed in the swivel 150, and internal threads 152 are formed at the bottoms of the mounting holes 151; the well cover 130 is provided with a plurality of through holes 131, the through holes 131 and the mounting holes 151 are correspondingly inserted with first bolts 160, and the first bolts 160 can be matched with the internal threads 152.

The bottom ring 110 is in threaded connection with the inner ring 120, the bottom ring 110 is generally installed in the ground, and the inner ring 120 can be lifted through rotation, so that the well lid 130 integrally connected with the inner ring 120 can be lifted conveniently, when the well lid 130 is not level with the ground, the well lid 130 can be rotated to be flush with the ground, the maintenance difficulty is greatly reduced, and the labor and the cost are reduced. Through the internal thread 152 cooperation in first bolt 160 and the mounting hole 151, can fix well lid 130, because, can rise after the well lid 130 is rotatory, and the distance of first bolt 160 and internal thread 152 can not change, so, well lid 130 just can not rotate, after well lid 130 adjusted the height, can fix the position through the cooperation of first bolt 160 and internal thread 152, can improve well lid 130's impact resistance through the setting of first bolt 160 moreover, the noise that produces when well lid 130 is pressed is less. When the height of the well lid 130 needs to be adjusted, the bottom end of the first bolt 160 is separated from the internal thread 152, so that the bottom end of the first bolt 160 is still located in the mounting hole 151, no thread exists at the top of the mounting hole 151 above the internal thread 152, that is, no thread exists at the top of the mounting hole 151, and the bottom is provided with threads, so that the height of the well lid 130 can be adjusted, when the height is adjusted, the position of the first bolt 160 can also rotate, but the bottom end of the first bolt 160 can drive the mounting hole 151 to rotate, namely, the swivel 150 is driven to rotate, and after the first bolt 160 reaches a new position, the first bolt 160 can still be correspondingly matched with the mounting hole 151 up and down, so that the height adjustment is very convenient.

The stop block 140 is arranged, so that the swivel 150 is convenient to install, and the swivel 150 is quite stable in the notch 112; the swivel 150 may improve the smoothness of rotation by the balls.

The bottom ring 110 is integrally connected to the convex ring 111 at a side thereof, and the stopper 140 is connected to the convex ring 111 by a second bolt 170.

The provision of the male ring 111 can improve stability of the bottom ring 110 when it is installed, and the connection ring 140 can disperse the inspection well cover into a plurality of parts, thereby facilitating production and installation of the inspection well cover.

The bottom ring 110 is perpendicular to the convex ring 111 and a reinforcing block 180 is provided between the bottom ring 110 and the convex ring 111.

The provision of the reinforcing blocks 180 can further enhance the stability of the bottom ring 110 in the ground.

The lower inner half of the mounting hole 151 is internally threaded 152.

The number of through holes 131, mounting holes 151 and stoppers 140 is three.

The three first bolts 160 can secure tightness at the time of fixation.

The well lid 130 is provided with an auxiliary hole 132 for facilitating rotation of the well lid 130.

The auxiliary hole 132 can facilitate rotation of the well lid 130.

The first bolt 160 is an M16 socket head cap bolt.

Since the sinking distance of the inspection well cover is generally smaller, the lifting distance of the inner ring 120 is smaller, so that the first bolt 160 can be ensured to be always positioned in the mounting hole 151, and the drawings in fig. 1-3 are schematic views and are not actual size ratios, and a person skilled in the art can obtain more suitable size ratios according to actual situations.

The utility model and its embodiments have been described above by way of illustration and not limitation, and the utility model is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto.
