Arc-shaped protrusions 3-2 are provided at right angles at both ends of the side grooves 3-1. The grate 2 is installed in the side grooves 3-1, and the grate 2 is plugged into the arc-shaped protrusions 3-2. A number of positioning grooves 3-3 are provided in the side grooves 3-1, and a number of positioning blocks 3-4 are provided on the bottom surface of the grate 2. The positioning blocks 3-4 are plugged into the positioning grooves 3-3. The bottom surface of the grate 2 is provided with reinforcing ribs 3-5. Notches 3-6 are provided on both side surfaces of the outer frame 1, and the notches 3-6 are connected to the side grooves 3-1. A pair of bottom grooves 3-7 are provided at the bottom of the grate 2, and the bottom grooves 3-7 correspond to the notches 3-6. A hook hole 3-8 is provided at the top of the bottom groove 3-7.

[0034] In this embodiment, in order to ensure that the grate 2 does not shake after installation, a loose installation component is designed. Side grooves 3-1 are provided on both sides of the surface of the outer frame 1, and arc-shaped protrusions 3-2 are provided at the right angles in the side grooves 3-1. The grate 2 is installed in the side grooves 3-1 and can reduce the wear caused by shaking and right-angle collision by fitting with the arc-shaped protrusions 3-2. A plurality of positioning grooves 3-3 are provided in the side grooves 3-1, and a position block is provided on the bottom surface of the grate 2 for inserting into the positioning grooves 3-3, which can increase the firm fitting effect. Notches 3-6 are provided on both sides of the outer frame 1, and two bottom grooves 3-7 and a hook hole 3-8 are provided at the bottom of the grate 2. The hook for the grate 2 can be inserted into the bottom groove 3-7 and the hook hole 3-8, and then the grate 2 can be pulled up.

[0035] Furthermore, the reinforcement support assembly 4 includes a pair of connecting grooves 4-1, which are opened on both sides of the bottom of the outer frame 1. A long hole 4-2 is opened on the inner surface of the connecting groove 4-1. A support frame 4-3 is slidably connected in the connecting groove 4-1. The side end surface of the support frame 4-3 is screwed with a fixing bolt 4-4 through a thread. A pre-fixed frame 4-5 is installed at the lower end of the support frame 4-3. Several connecting holes 4-6 are opened on the top and bottom of the pre-fixed frame 4-5 and the surface of the support frame 4-3.

[0036] In this embodiment, in order to achieve the effect of strengthening the anti-subsidence support of the outer frame 1, a reinforced support component 4 is designed. A pair of connecting grooves 4-1 are opened at both ends of the bottom of the outer frame 1, and a long hole 4-2 is opened on one side of the connecting groove 4-1. A support frame 4-3 is slidably connected in the connecting groove 4-1 and is screwed with a fixing bolt 4-4. The fixing bolt 4-4 is located in the long hole 4-2 and can be tightened to fix the outer frame 1. The position of the support frame 4-3 can be adjusted.

[0039] Furthermore, the positioning groove 3 - 3 and the positioning block 3 - 4 are both conical structures.

[0040] In this embodiment, the conical structure can form an extrusion effect after the positioning block 3-4 is inserted into the positioning groove 3-3, and fits tightly, so that the grate 2 will not shake when it is squeezed by gravity.

[0041] Furthermore, the cross-section of the connecting portion between the connecting groove 4-1 and the supporting frame 4-3 is a T-shaped structure.

[0042] In this embodiment, the T-shaped structure prevents the support frame 4-3 from falling off when moving in the connecting groove 4-1.

[0043] When it is needed, first insert the pre-fixed frame 4-5 into the fastener through the connecting hole 4-6 and fix it in the bottom of the well. After fixing, adjust the position of the support frame 4-3 according to the distance between the two pre-fixed frames 4-5. First loosen the fixing bolt 4-4 and then push the support frame 4-3 to move and adjust in the connecting groove 4-1. After the adjustment is completed, tighten the fixing bolt 4-4 again. The lower end of the support frame 4-3 fits on the pre-fixed frame 4-5, and the connecting pin can be inserted in the connecting hole 4-6 in advance. Finally, fix the outer frame 1. When the grate 2 needs to be opened, insert the hook into the notch 3-6 on both sides and pass it through the hook hole 3-8, and then lift the grate 2.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
