[0043] The embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0044] like Figure 1 , Figure 2 As shown, the utility model proposes an adjustable hole protection device, including a central frame 10, a first extension frame 20, a second extension frame 30 and a fixing clamp 60: wherein the central frame 10 is provided with a middle cross beam 101 and a longitudinal beam 102; the first extension frame 20 is movably connected to the longitudinal beam 102, and can move along the length direction of the longitudinal beam 102; the second extension frame 30 is movably connected to the middle cross beam 101 and the first extension frame 20, and can move along the length direction of the middle cross beam 101; the fixing clamp 60 is detachably arranged on the central frame 10, and is opposite to the first extension frame 20, and is used to fix the central frame 10 at the hole position.

[0045] In a specific embodiment, when using the present device, the central frame 10 is placed at the opening to be protected, and the first extension frame 20 is adjusted according to the height of the opening so that the height of the entire device is higher than the upper end of the opening; then the second extension frame 30 is adjusted according to the width of the opening so that the connection width between the first extension frame 20 and the central frame 10 exceeds the width of the opening to meet the protection requirements of the opening, and finally the fixing clamp 60 is installed to fix the entire device.

[0046] Among them, the adjustment order when using this device can be carried out as needed. The second extension frame 30 can be adjusted first to meet the protection width requirement, and then the first extension frame 20 can be adjusted to meet the protection height requirement, and then the entire device can be fixed to the hole, which can achieve good protection effect.

[0047] The central frame 10, the first extension frame 20 and the second extension frame 30 of the present application are connected together when not in use and when in use, have good integrity and stability, are convenient for overall transportation and installation, and can be applied to openings of different sizes, saving material use and installation time, simplifying installation operations, and helping to ensure the installation quality of the protective device.

[0048] Furthermore, if Figure 1 , Figure 2 As shown, the first extension frame 20 is inserted into the longitudinal beam 102 through the connecting longitudinal rod 201. In this embodiment, the longitudinal beam 102 of the central frame 10 is a hollow structure, and the cross-sectional size of the longitudinal beam 102 matches the shape of the connecting longitudinal rod 201, so that the connecting longitudinal rod 201 is inserted into the longitudinal beam 102 and can be extended and retracted along the longitudinal beam 102, so that the height of the first extension frame 20 can be more conveniently adjusted to be suitable for holes of different sizes.

[0049] Furthermore, the middle crossbeam 101 of the central frame 10 is vertically connected to the longitudinal beam 102, both of which are hollow structures, and the cavities after the two are connected are interconnected; the middle crossbeam 101 is connected to the middle of the longitudinal beam 102, and the middle crossbar 301 of the second extension frame 30 is inserted into the middle crossbeam 101; wherein, the connection portion between the middle crossbeam 101 and the longitudinal beam 102 is set according to the length of the connecting longitudinal rod 201, and this setting enables the first extension frame 20 and the second extension frame 30 to achieve better cooperation, and can be moved and adjusted separately without affecting each other; specifically, the longitudinal beam 102 has a cavity of sufficient length to enable the first extension frame 20 to move in the cavity. It can be understood that the length of the cavity is the moving range of the connecting longitudinal rod 201, that is, the height adjustment range of the first extension frame 20; when the middle crossbar 301 of the second extension frame 30 passes through the longitudinal beam 102 and is inserted into the middle crossbeam 101, it will not hinder the movement of the second extension frame 30. This design connects the middle cross beam 101 and the longitudinal beam 102 together, thereby improving the integrity of the device, making the device sufficiently rigid and easy to adjust, and saving materials.

[0050] In a specific implementation, Figure 1 As shown, the adjustable hole protection device proposed in the present application includes a central frame 10, a first extension frame 20 and two second extension frames 30, and the two second extension frames 30 are respectively located at the two ends of the central frame 10; specifically, the central frame 10 has two longitudinal beams 102, which are respectively arranged at the two ends of the middle cross beam 101; correspondingly, the first extension frame 20 is provided with two connecting longitudinal rods 201, which are respectively inserted into the two longitudinal beams 102; the two second extension frames 30 are both provided with a middle cross rod 301, which passes through the two longitudinal beams 102 and is inserted into the middle cross beam 101; when in use, one of the second extension frames 30 can be adjusted as needed, or the two second extension frames 30 can be adjusted separately to adapt to the width of the hole and meet the protection requirements.

Specifically, one end of the vertical rod 304 is inserted in the side beam 303, and the other end is vertically connected to the top cross bar 302; when the connecting longitudinal rod 201 of the first extension frame 20 moves in the longitudinal beam 102 of the central frame 10, the vertical rod 304 moves synchronously in the side beam 303. This arrangement improves the integrity of the device and does not affect the movement of the first extension frame 20; at the same time, a roller 305 is provided at the other end of the side beam 303. When in use, the roller 305 contacts the ground at the opening.
