[0035] like Figure 1 and Figure 2As shown in the figure, an embodiment of the present invention provides a hole covering and protection device, including a support assembly and a cover plate 10. The support assembly is disposed on the hole 50 and engages with the hole 50. The support assembly is separately disposed and can be extended or shortened. The cover plate 10 is disposed on the support assembly. The separate design of the support assembly is more conducive to adapting to holes 50 of different sizes, and the support assembly can be extended or shortened according to the size of the hole 50. The engaging installation of the support assembly with the hole 50 facilitates the disassembly of the protective device. By setting up the support assembly, the cover plate 10 can be effectively supported. The cover plate 10 can be made of hard alloy material to improve the strength of the cover plate 10, prevent the cover plate 10 from deforming under stress, and have good waterproof performance.

[0036] Specifically, the support components include end support components 20 and intermediate support components 30. The end support components 20 are located at both ends of the opening 50, and the intermediate support components 30 are located between the end support components 20. A certain distance is maintained between each support component. The number of intermediate support components 30 is not limited. Depending on the size of the opening 50, different numbers of intermediate support components 30 can be selected to effectively distribute the load and prevent the cover plate 10 from bending and deforming under gravity and external loads. Larger openings 50 can accommodate more intermediate support components 30, while smaller openings 50 can accommodate fewer intermediate support components 30.

[0037] Specifically, such as Figure 3 As shown, the end support assembly 20 includes a first support member 21, a second support member 22, and an end positioning member. The first support member 21 and the second support member 22 are coaxially arranged. One end of the first support member 21 is sleeved on one end of the second support member 22 and slidably connected to it, meaning the first support member 21 can slide along the second support member 22, thereby adjusting the length of the entire end support assembly 20. The end positioning member is located at the non-connecting ends of the first support member 21 and the second support member 22, at both ends of the end support assembly 20, and is used for end positioning of the cover plate 10. Preferably, the first support member 21 is a rectangular tube, and the second support member 22 is a plate with a certain thickness, with one end of the rectangular tube sleeved on one end of the plate.

[0038] Specifically, to prevent relative movement between the first support member 21 and the second support member 22 during the protection process, the end support assembly 20 also includes a first positioning pin 25. The first positioning pin 25 is disposed on the first support member 21, passing through the first support member 21 and abutting against the second support member 22. The first positioning pin 25 is threadedly connected to the first support member 21. Tightening the first positioning pin 25 allows its screw-in end to abut against the second support member 22, thereby securing the first support member 21 and the second support member 22. Loosening the first positioning pin 25 allows adjustment of the length of the end support assembly 20. Preferably, the first positioning pin 25 is configured as a positioning bolt. The number of first positioning pins 25 is not specifically limited.

[0039] Specifically, the end positioning components include a first positioning component 23 and a second positioning component 24. The first positioning component 23 and the second positioning component 24 are set at right angles and are used to engage the end of the cover plate 10. The first positioning component 23 and the second positioning component 24 are vertically arranged baffles, located at the non-connecting ends of the first support component 21 and the second support component 22, and are fixedly connected to or integrally formed with the first support component 21 or the second support component 22. The first positioning component 23 is located at the end of the first support component 21 and the second support component 22, and the second positioning component 24 is located on the side of the first support component 21 and the second support component 22 near the inner wall of the opening 50. The first positioning component 23 and the second positioning component 24 are set at right angles, which is more conducive to engaging the two corners of the end of the cover plate 10 and positioning the cover plate 10. By setting the right-angle end positioning components, the corners of the opening 50 can also be protected.

[0040] Specifically, such as Figure 4 As shown, the intermediate support assembly 30 includes a third support member 31, a fourth support member 32, and an intermediate positioning member 33. The third support member 31 and the fourth support member 32 are coaxially arranged, with one end of the third support member 31 sleeved on one end of the fourth support member 32 and slidably connected to it. This means the third support member 31 can slide along the fourth support member 32, thereby adjusting the length of the entire intermediate support assembly 30. The intermediate positioning member 33 is located at the non-connecting ends of the third support member 31 and the fourth support member 32, at both ends of the intermediate support assembly 30, and is used to engage the two sides of the cover plate 10. Preferably, the third support member 31 is a rectangular tube, and the fourth support member 32 is a plate with a certain thickness, with one end of the rectangular tube sleeved on one end of the plate. Preferably, the intermediate positioning member 33 is a vertically arranged baffle, fixedly connected to or integrally formed with the third support member 31 or the fourth support member 32.

[0041] Specifically, to prevent relative movement between the third support member 31 and the fourth support member 32 during the protection process, the intermediate support assembly 30 also includes a second positioning pin 34. The second positioning pin 34 is disposed on the third support member 31, passing through the third support member 31 and abutting against the fourth support member 32. The second positioning pin 34 is threadedly connected to the third support member 31. Tightening the second positioning pin 34 allows its screw-in end to abut against the fourth support member 32, thereby securing the third support member 31 and the fourth support member 32. Loosening the second positioning pin 34 allows adjustment of the length of the intermediate support assembly 30. Preferably, the second positioning pin 34 is configured as a positioning bolt. The number of second positioning pins 34 is not specifically limited.

[0042] Specifically, such as Figure 3 and Figure 4 As shown, the bottom of the first support member 21, the second support member 22, the third support member 31, and the fourth support member 32 are all provided with protrusions 40, which can engage with the opening 50. By setting the protrusions 40 to form a step shape, the protrusions 40 can engage with the inner wall of the opening 50, thereby positioning the first support member 21, the second support member 22, the third support member 31, and the fourth support member 32.

[0043] Preferably, in order to accommodate smaller openings 50, the protrusions 40 of the second support member 22 and the fourth support member 32 are provided with engaging grooves 41 on the side near the first support member 21 and the third support member 31, so that the first support member 21 and the third support member 31 can continue to move and engage within the protrusions 40 of the second support member 22 or the fourth support member 32, thereby accommodating smaller openings 50, such as... Figure 5 As shown.

[0044] Preferred, such as Figure 1 As shown, the cover plate 10 is configured as a split unit, comprising multiple spliced ​​split cover plates 10. By using spliced ​​split cover plates 10, it is easier to accommodate openings 50 of different sizes. The number of split cover plates 10 is determined according to the size of the opening 50. Larger openings 50 require more split cover plates 10, while smaller openings 50 require fewer split cover plates 10, making installation more flexible.

[0045] A method of using the opening covering and protection device as described above includes the following steps:

[0046] S1: Adjust the length of the support component;

[0047] Loosen the first positioning pin 25, and adjust the relative positions of the first support member 21 and the second support member 22 according to the size of the opening 50, thereby adjusting the length of the end support assembly 20. Loosen the second positioning pin 34, and adjust the relative positions of the third support member 31 and the fourth support member 32 according to the size of the opening 50, thereby adjusting the length of the intermediate support assembly 30.

[0048] S2: The support component is separately installed on the opening 50 and engaged with the opening 50;

[0049] The end support components 20 are snapped into place at both ends of the opening 50, and multiple intermediate support components 30 are placed at intervals between the end support components 20 according to the size of the opening 50.
