Referring to fig. 1-6, a steel grating with adjustable height includes a housing 1, a grating 2 is slidably connected to an inner wall of the housing 1, four surfaces of the housing 1 are all provided with bolts 8, the other end of each bolt 8 penetrates the inner side of the housing 1, a surface of each bolt 8 is in threaded connection with an inner wall of a penetrating portion of the housing 1, one side of an inner cavity of the grating 2, which is far away from the housing 1, is provided with a fixing groove 4, two sides of each fixing groove 4 are provided with a limiting groove 5, a surface of each bolt 8 is in threaded connection with a nut 6, two sides of each nut 6 are respectively provided with a limiting plate 7, a surface of each limiting plate 7 is in sliding connection with an inner wall of each limiting groove 5, bottom portions of four corners of the inner wall of the housing 1 are respectively provided with a supporting mechanism 10, the steel grating is inserted into the different limiting grooves 5 through the limiting plates 7, so that the height of the grating 2 can be adjusted, a drop between the ground and the grating 2 is reduced, so that a connection position of the grating is smoother, a person cannot trip due to the steel grating when walking, and the person is injured, and the grating can be mounted on the ground more conveniently, and the problem that the steel grating can be solved when the grating is mounted on the ground.

Supporting mechanism 10 is including installation shell 101, the bottom of installation shell 101 inner chamber is fixed with compression spring 104, compression spring 104's the other end is fixed with fixed plate 103, the surface of fixed plate 103 and the inner wall sliding connection of installation shell 101, the top of fixed plate 103 is fixed with installation pole 102, the other end of installation pole 102 has the bottom fixed connection of check board 2, in this embodiment, through installation shell 101, fixed plate 103, the setting of installation pole 102 and compression spring 104, can make installation pole 102 can drive check board 2 rebound through compression spring 104, make it not need the staff to stimulate check board 2 with the hand, staff's the amount of labour has been reduced, also make the staff more convenient when the installation simultaneously.

Recess 3 has all been seted up to four faces in the shell 1 outside, and the internal diameter of recess 3 is greater than the diameter of the biggest department of bolt 8, and in this embodiment, through the setting of recess 3, can hide the outstanding one side of bolt 8, makes it can not outstanding to the outside of shell 1 and influence being connected between grating 2 and the ground.

The top on grid 2 surface is fixed with baffle 9, and the width of baffle 9 is the same with the width of shell 1, and in this embodiment, through the setting of baffle 9, can block the thickness of shell 1, makes it can not lead to grid 2 and ground junction to have great gap because of the thickness of shell 1 after the installation.

One side diameter of bolt 8 is less than the width of fixed slot 4, and the diameter of nut 6 is greater than the width of fixed slot 4, and in this embodiment, through this kind of setting, can make nut 6 extrude grating 2 through being connected of bolt 8 and nut 6, make it can fix more stably.

The quantity of spacing groove 5 is a plurality of, and evenly distributed is in the both sides of fixed slot 4, and in this embodiment, through this kind of setting, can change the position of nut 6 according to spacing groove 5 of difference to make grid 2 can adjust out different heights.

The working principle is as follows: first put shell 1 in the spread groove of the sewer that needs to lay, then observe whether the top of check board 2 is parallel and level with ground, under the state of parallel and level, need not change the height of check board 2, continue to lay can, and when being less than the ground, take off nut 6 and limiting plate 7, then under compression spring 104's effect, make compression spring 104 drive check board 2 rebound through installing rod 102, do not need the staff to mention check board 2 with the hand, then the staff tramples on check board 2 with the foot, make the height of check board 2 and ground parallel and level, then overlap nut 6 on the surface of bolt 8, bolt 8 drives limiting plate 7 afterwards and inserts in the spacing groove 5 that corresponds the height, make nut 6 can fix, rotate bolt 8 with appurtenance immediately, make bolt 8 can move to nut 6 department, make check board 2 extrude shell 1, make check board 2 can fix, fix it at the same height with ground, afterwards adjust the position of nut 6 in proper order, make it can with ground, in the same reason, when the height of check board 2 is higher than ground, also can adjust it.
