DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0033] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0034] like Figures 1 to 8 As shown, the present application provides a temporary cover with reserved holes for easy removal, including an outer frame 1, a transverse load-bearing beam 11 and a longitudinal load-bearing beam 12 provided on the inner side of the outer frame 1, a lap groove 2 provided on one side of the outer frame 1, a lap block 3 adapted to the lap groove 2 provided on the other side of the outer frame 1, and a clamping groove 31 provided at both ends of the lap block 3;

[0035] A sliding groove 21 connected to the overlapping groove 2 is symmetrically provided inside the outer frame 1, and a snap-in block 22 is slidingly provided inside the sliding groove 21. An elastic member 23 is provided inside the sliding groove 21, and the elastic member 23 is preferably a spring. An inclined surface 221 is formed on one side of the snap-in block 22, and the snap-in block 22 is adapted to the snap-in groove 31.

[0036] In this embodiment, when placing the temporary cover, first place one group of outer frames 1 on the ground and cover other reserved holes on the ground such as sewage channels or cable troughs. Then align the overlapping blocks 3 of another group of outer frames 1 with the overlapping grooves 2 of the placed outer frames 1, and then place them downward so that the overlapping blocks 3 are squeezed into the overlapping grooves 2. Since one side of the clamping block 22 is an inclined surface 221, when the overlapping block 3 moves into the overlapping groove 2, it squeezes the clamping block 22 into the slide groove 21 and causes the elastic member 23 to deform. When the overlapping block 3 is placed in the overlapping groove 2, the clamping block 22 is moved into the clamping groove 31 under the elastic force of the elastic member 23, thereby fixing the overlapping block 3 in the overlapping groove 2, so that the two cover plates can be firmly connected, preventing the cover plates from shifting under the action of external force, and avoiding the risk of people falling.

[0037] like Figures 1 to 2 As shown, multiple groups of transverse load-bearing beams 11 are arranged at equal intervals along the length direction of the outer frame 1, and multiple groups of longitudinal load-bearing beams 12 are arranged at equal intervals along the width direction of the outer frame 1, and the transverse load-bearing beams 11 and the longitudinal load-bearing beams 12 are arranged in a staggered manner.

[0038] In this embodiment, the load can be effectively dispersed by a plurality of groups of staggered transverse load-bearing beams 11 and longitudinal load-bearing beams 12, so that the load is evenly distributed in multiple directions, thereby increasing the stability of the overall structure.

[0039] like Figure 2 As shown, a plurality of through holes 13 are formed alternately between the transverse load-bearing beam 11 and the longitudinal load-bearing beam 12 .

[0040] In this embodiment, the through hole 13 can facilitate the operator to take the entire cover plate. The provision of the through hole 13 can reduce the overall weight and reduce the amount of material used.

[0041] like Figures 4 to 8 As shown, a slider 24 is provided between the clamping block 22 and the elastic member 23 , and the slider 24 is slidably connected to the inside of the sliding groove 21 .

[0042] In this embodiment, when the clamping block 22 is squeezed, the clamping block 22 drives the sliding block 24 to slide along the inside of the sliding groove 21 , and squeezes the elastic member 23 through the sliding block 24 .

[0043] As shown in FIG5 , a through slot 26 is provided inside the outer frame 1 , and the through slot 26 is connected to the slide slot 21 . A sliding rod 241 is provided at the upper end of the slider 24 , and the sliding rod 241 slides through the through slot 26 .

[0044] In this embodiment, when multiple sets of cover plates need to be separated, the sliding rod 241 is pulled, and the sliding rod 241 drives the slider 24 to move, so that the slider 24 drives the clamping block 22 to move, so that the clamping block 22 is separated from the clamping groove 31, and it can be disassembled.

[0045] like Figure 5 and Figure 8 As shown, a groove 27 communicating with the through groove 26 is formed on the top surface of the slide groove 21 , and a pull plate 242 is provided on the top of the sliding rod 241 , and the pull plate 242 is slidably connected to the inside of the groove 27 .

[0046] In this embodiment, the provision of the pull plate 242 enables the operator to pull the sliding rod 241 more easily, making it more convenient to use.

[0047] like Figure 7 and Figure 8 As shown, the inner part of the outer frame 1 is symmetrically provided with a limiting groove 25 connected with the sliding groove 21 , and the outer side of the slider 24 is symmetrically provided with a limiting block 243 , which is slidably connected to the limiting groove 25 .

[0048] In this embodiment, when the slider 24 moves along the inside of the slide groove 21, the limit block 243 moves along the inside of the limit groove 25, and the slider 24 is limited by the limit groove 25 and the limit block 243 to prevent it from moving excessively and preventing it from being separated from the slide groove 21.

[0049] like Figure 8 As shown, the top surface of the pull plate 242 and the top surface of the outer frame 1 are on the same horizontal line.

[0050] In this embodiment, since the top surface of the pull plate 242 is on the same horizontal line as the top surface of the outer frame 1 , it is possible to effectively prevent workers from being tripped by the pull plate 242 when walking on top of the outer frame 1 .

[0051] like Figure 5 and Figure 8 As shown, the width of the groove 27 is greater than the width of the pull plate 242 .

[0052] In this embodiment, since the width of the groove 27 is greater than the width of the pull plate 242 , the pull plate 242 can be prevented from getting stuck with the side wall of the groove 27 , and it is also more convenient for the operator to pull the pull plate 242 .

[0053] like Figure 9 As shown, the bottom surface of the outer frame 1 is provided with barbs 4, and the barbs 4 are arranged in multiple groups with equal intervals along the path direction.

[0054] In this embodiment, the barbs 4 provided at the bottom of the outer frame 1 can effectively increase the friction between the outer frame 1 and the ground, thereby preventing the cover from sliding on the ground and further improving safety.

[0055] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
