The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0021] Embodiment 1:

[0022] Reference Figure 1-Figure 4 A wire-laying hole protection device comprises an L-shaped support plate 1, which is symmetrically arranged on both sides of the wire-laying hole, and the adjacent sides of the two L-shaped support plates 1 are fixedly connected with screw rods 101, and a sleeve 102 is arranged between the two screw rods 101, and the sleeve 102 is threadedly connected with the two screw rods 101, and also comprises: an adjusting plate 2, which slides on the upper surface of the L-shaped support plate 1, and an adjusting opening 201 is opened on the adjusting plate 2; a locking bolt 202 is inserted into the adjusting opening 201, and a threaded hole used in conjunction with the locking bolt 202 is opened on the L-shaped support plate 1; and a protective plate 203, which is rotatably connected to the side of the adjusting plate 2 close to the sleeve 102.

[0023] When installing the device on the wire-laying hole, so that the wire-laying hole can be closed when not in use to avoid safety accidents, first take the device to the wire-laying hole on each floor, then the two L-shaped support plates 1 can be clamped on both sides of the wire-laying hole, and then the sleeve 102 can be rotated. At this time, the two screw rods 101 will drive the two L-shaped support plates 1 away from each other under the action of the thread, until the two L-shaped support plates 1 are tightly against the side walls of the wire-laying hole, and then the adjustment plate 2 connecting the protective plate 203 can be placed on the L-shaped support plate 1, and the two protective plates 203 are abutted against each other, and the adjustment port 201 on the adjustment plate 2 is aligned with the threaded hole on the L-shaped support plate 1, and then the locking bolt 202 can be inserted into the adjustment port 201 is rotated into the threaded hole, so that the installation of the device can be completed. When the staff needs to use a plumb bob to perform line-laying measurement operations, the protective plate 203 can be flipped over to open the line-laying holes of each layer for line-laying measurement. Through the coordinated use of components such as the L-shaped support plate 1, the screw rod 101, the sleeve 102, the adjustment plate 2, the adjustment port 201, the locking bolt 202, and two protective plates 203, compared with the prior art, not only can the device be quickly disassembled and assembled to improve the convenience of use, but the position of the protective plate 203 can also be adjusted accordingly according to the size of the line-laying hole, so that line-laying holes of different specifications can be well protected, effectively improving the applicability of the device.

[0024] Embodiment 2:

[0025] Reference Figure 1-Figure 4 , a wire-laying hole protection device is basically the same as Example 1, and further: a plurality of adjustment openings 201 are opened on the adjustment plate 2. Through the setting of the plurality of adjustment openings 201, when the adjustment plate 2 is fastened to the L-shaped support plate 1 by the locking bolts 202, the connection between the adjustment plate 2 and the L-shaped support plate 1 can be made more stable, avoiding the protection plate 203 from tilting when the switch protection plate 203 is opened, thereby affecting the protection effect of the wire-laying hole.

[0026] The screw rod 101 is symmetrically fixedly connected to both sides of the L-shaped support plate 1. By symmetrically arranging two groups of screw rods 101 and sleeves 102, when installing the device, the two L-shaped support plates 1 can be more stably fixedly installed on both sides of the wire-laying hole, thereby effectively improving the stability of the device.

[0027] Embodiment 3:

[0028] Reference Figure 1-Figure 4 A wire-laying hole protection device is basically the same as Example 2, and further: the protection plate 203 is a steel plate. By making the protection plate 203 of a steel plate, the strength of the protection plate 203 can be improved, and the protection plate 203 can be prevented from being deformed and affecting the use when a worker steps on the protection plate 203.

[0029] The lower side of the protective plate 203 is symmetrically fixedly connected with a second bearing rod 204, and the lower ends of the two second bearing rods 204 are respectively abutted against the sleeve 102 on the same side. One side of the screw rod 101 is fixedly connected with a first bearing rod 103, and the lower end of the first bearing rod 103 is fixedly connected to the L-shaped support plate 1 on the same side. Through the arrangement of the first bearing rod 103 and the second bearing rod 204, the protective plate 203 can be supported, thereby further improving the protection effect of the protective plate 203.

[0030] The upper surface of the protective plate 203 is provided with a luminous coating 205. By providing the luminous coating 205 on the upper surface of the protective plate 203, when the light is poor at night, it can emit light to remind workers of the location of the device to prevent workers from stepping on the device. At the same time, it is convenient for quickly identifying the location of the wire laying hole when performing wire laying operations at night.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
