Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0027] like Figures 1 to 6 As shown, the floor opening protective cover includes a cover plate 1, a bracket 2, and a limiting component 3.

[0028] Specifically, the cover plate 1 has an extension plate on its periphery to cover the support 2 below, preventing the support legs of the support 2 from causing accidental injury to workers. The cover plate 1 covers the outside of the floor opening to protect the floor opening. Four connecting sleeves 11 arranged in a rectangular frame are fixed in the middle of the lower surface of the cover plate 1. Multiple support blocks 12 are fixed at equal intervals along the lower edge of the cover plate 1. The lower surface of the support blocks 12 corresponds to the end of the support legs of the support 2.

[0029] Specifically, the bracket 2 is located below the cover plate 1 to support the cover plate 1. A connecting block 21 is fixed on the upper surface of the node of the bracket 2. The connecting block 21 is adapted to the connecting sleeve 11 to limit the cover plate 1 and the bracket 2. A linear slot 22 is provided on each leg of the bracket 2. Limiting grooves 23 are provided on the inner walls of both sides of the linear slot 22. The linear slot 22 is used to install the limiting component 3.

[0030] More specifically, the limiting member 3 is installed at multiple feet of the bracket 2, and its position is adjusted according to floor openings of different widths, and it is fitted with the inner wall of the opening, so as to limit the bracket 2. The limiting member 3 includes a limiting plate 31 provided on the lower surface of the foot. The limiting plate 31 is arranged in an inverted L-shaped structure, and a triangular reinforcing plate is provided in the middle of the limiting plate 31. A movable block 32 is fixed on the upper surface of the limiting plate 31. The movable block 32 is located in the linear empty groove 22. Limiting sliders 33 are fixed on both sides of the movable block 32. The limiting sliders 33 are located in the limiting sliding grooves 23 and are used to limit the movable block 32 in the linear empty groove 22. A sliding plate 35 is fixed on the top of the movable block 32. The sliding plate 35 is arranged in a "冂" shape structure. Thread grooves 36 are opened on both sides of the sliding plate 35. A limiting knob 37 is connected to the inside of the thread groove 36 through internal and external threads. The limiting knob 37 corresponds to the side wall of the foot and is used to limit the movable block 32 and the limiting plate 31. And the movable block 32 is connected to one end of the linear empty groove 22 through a spring 34 (Although not clearly mentioned in the original text, it is supplemented according to the working principle).

[0031] When the device is working, first move multiple limiting plates 31 towards the middle of the bracket 2, then limit the limiting plates 31 by turning the limiting knobs 37. Then place the bracket 2 at the opening, and then turn the limiting knobs 37 to release the limit of the limiting plates 31. At this time, the multiple limiting plates 31 are reset under the action of the spring 34 until the multiple limiting plates 31 all move to contact the inner wall of the opening. At this time, turn the limiting knobs 37 again to limit the limiting plates 31 again. The multiple limiting plates 31 cooperate to limit the bracket 2 at the opening. Then cover the cover plate 1 on the bracket 2, and make the multiple connecting sleeves 11 on the cover plate 1 correspond to the connecting blocks 21 on the bracket 2 until the connecting blocks 21 are stuck into the connecting sleeves 11. At this time, the cover plate 1 is limited on the bracket 2. At the same time, multiple supporting blocks 12 on the cover plate 1 contact the bracket 2 and play a supporting role, so that the cover plate 1 can support the staff walking on it.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
