Background
In the building construction process, some temporary construction wells or temporary construction holes are often formed, and the construction wells or temporary construction holes are sometimes required to be reserved for a whole construction period, so that some protective measures are required to be taken on the temporary holes or construction holes. Construction waste such as steel plates or wood plates are generally used to cover the opening of the hole to prevent danger to the constructors. The steel plate or the wood plate can be displaced under the action of external force sometimes, so that the opening is exposed to cause danger, and the steel plate or the wood plate is simple and crude in appearance, has no obvious mark and is difficult to move or cover.
SUMMERY OF THE UTILITY MODEL
The utility model provides an interim protector in construction entrance to a cave, structural design is reasonable, opens or covers convenient operation, safe and reliable.
In order to achieve the above object, the utility model adopts the following technical scheme:
the temporary protection device for the construction hole comprises a first cover plate, a second cover plate, a third cover plate and a limiting ejector rod, wherein the third cover plate is connected with the second cover plate in an inserting mode, the first cover plate is hinged to the second cover plate, a second baffle plate is arranged at the end part of one side, connected with the three phase of the second cover plate, a third baffle plate is arranged at the end part of one side, connected with the two phase of the second cover plate, of the third cover plate, the third baffle plate is provided with an inserting hole, the second cover plate is inserted into the inserting hole of the third baffle plate, one end of the limiting ejector rod is hinged.
A first handle and a second handle are fixed at one end of the first cover plate, the first handle and the second handle are respectively arranged on two surfaces of the first cover plate, a connecting shaft is arranged at the other end of the first cover plate, and the first cover plate is hinged with the second cover plate through the connecting shaft.
And side limiting plates are arranged on two sides of the third cover plate, the second cover plate slides between the side limiting plates, and a construction hole positioning plate is fixed at the bottom of the third cover plate.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model relates to an interim protector in construction entrance to a cave, structural design is reasonable, opens or covers convenient operation, safe and reliable. The utility model discloses scalable, the length is adjustable, and is recoverable recycles, and the high-usage.

Fig. 3 is a view from a-a of fig. 2.
Fig. 4 is a construction application diagram of the present invention.
In the figure: 1-cover plate I, 1-1 handle I, 1-2 handle II, 2-cover plate II, 2-1 baffle II, 3-cover plate III, 3-1 construction opening positioning plate, 3-2 baffle III, 3-3 side limiting plate, 4-connecting shaft, 5-iron ring, 6-limiting ejector rod and 6-1 positioning plate.
Detailed Description
The following further describes the embodiments of the present invention with reference to the drawings:
as shown in fig. 1-4, the temporary protection device for the construction opening comprises a first cover plate 1, a second cover plate 2, a third cover plate 3 and a limiting ejector rod 6, wherein the third cover plate 3 is connected with the second cover plate 2 in an inserted manner, the first cover plate 1 is hinged to the second cover plate 2, a second baffle plate 2-1 is arranged at the end part of the side, connected with the third cover plate 3, of the second cover plate 2, a third baffle plate 3-2 is arranged at the end part of the side, connected with the second cover plate 2, of the third cover plate 3, the third baffle plate 3-2 is provided with an insertion hole, the second cover plate 2 is inserted into the insertion hole of the third baffle plate 3-2, one end of the limiting ejector rod 6 is hinged to the third baffle plate 3-2, and the other end of.
One end of the cover plate I1 is fixedly provided with a first handle 1-1 and a second handle 1-2, the first handle 1-1 and the second handle 1-2 are respectively arranged on two surfaces of the cover plate I1, the other end of the cover plate I1 is provided with a connecting shaft 4, and the cover plate I1 is hinged with the cover plate II 2 through the connecting shaft 4. An iron ring 5 is welded and fixed on the second cover plate, and two ends of the connecting shaft 4 are inserted into the iron ring 5, so that the first cover plate 1 is hinged to the second cover plate 2.
Two sides of the third cover plate 3 are provided with side limiting plates 3-3 (shown in figure 3), the second cover plate 2 slides between the side limiting plates 3-3, and a construction hole positioning plate 3-1 is fixed at the bottom of the third cover plate 3.
The side limiting plate 3-3 is mainly arranged to enable the cover plate 2 to slide along a straight line without being blocked when the cover plate is stretched on the cover plate 3. And a construction hole positioning plate 3-1 fixed at the bottom of the cover plate III 3 is matched with the width of the hole, so that the cover plate cannot move to be connected with the hole due to external force. The cover plate 1 can be lifted and covered. The second cover plate 2 is telescopic to adjust the overall length of the cover plate, and the positioning plate 6-1 on the limiting ejector rod 6 can be clamped on the second baffle plate 2 to temporarily position the second cover plate 2 and the third cover plate 3.
