[0020] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

[0021] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-4 This utility model provides a metal frame with anti-tipping function, including a metal frame 1, a top plate 11 fixedly connected to the top of the metal frame 1, two symmetrically distributed slide rails 2 fixedly connected to the upper side wall of the top plate 11, at least two positioning members 3 slidably arranged between the two slide rails 2, a housing 4 fixedly connected to the middle of the positioning member 3, a guide cylinder 5 fixedly connected to the top wall of the housing 4, a support cylinder 6 provided inside the guide cylinder 5, a support plate 7 fixedly connected to the top of the support cylinder 6, and an adjustment component 8 provided inside the housing 4. By adjusting the component 8, the support plate 7 can be tightly pressed against the ceiling. When the metal frame 1 tilts, it will change its angle. With the support plate 7 tightly pressed against the ceiling, the metal frame 1 has no space to tilt, thereby achieving the purpose of preventing the metal frame 1 from tilting and ensuring the safety of the metal frame 1 during use.

[0024] Specifically, such as Figure 4As shown, a metal frame with anti-tipping function includes an adjustment component 8 comprising a screw 81, a worm gear 82, a worm 83, and a handwheel 84. The screw 81 is rotatably mounted at the center of the lower inner wall of the housing 4. The upper end of the screw 81 extends into the support cylinder 6 and is threadedly connected to the inner wall of the support cylinder 6. The worm gear 82 is fixedly sleeved on the screw 81 within the housing 4. A worm 83, meshing with the worm gear 82, is rotatably connected to one side inner wall of the housing 4. The other end of the worm 83 passes through the other side wall of the housing 4 and is fixedly connected to the handwheel 84. Rotating the handwheel 84 drives the worm 83 to rotate, which in turn drives the worm gear 82 to rotate the screw 81. When the screw 81 rotates, it causes the threaded support cylinder 6 to move the support plate 7 upward, making the support plate 7 tightly abut against the ceiling. This design is suitable for ceilings of different heights, offering greater versatility.

[0025] Specifically, such as Figure 2 As shown, a metal frame with anti-tipping function has several equidistant through holes 21 on the side wall of the two slide rails 2 that are far apart from each other.

[0026] Specifically, such as Figure 2 As shown, a metal frame with anti-tipping function has threaded grooves 31 on both sides of the positioning member 3.

[0027] Specifically, such as Figure 2 As shown, a metal frame with anti-tipping function has a bolt 22 inserted in the through hole 21. The bolt 22 is threadedly connected to the threaded groove 31. After the bolt 22 is removed, the position of the positioning part 3 can be changed, thereby changing the position of the support plate 7, so that the abutment position can be freely adjusted. It is suitable for some ceilings with height differences caused by suspended ceilings.

[0028] Specifically, such as Figure 3 As shown, a metal frame with anti-tipping function has two symmetrically distributed guide grooves 51 on the inner wall of the guide cylinder 5. The support cylinder 6 is slidably engaged with the guide grooves 51. The guide grooves 51 provide guidance to the support cylinder 6 when it moves, so that it can only move in a straight line.

[0029] It should be noted that this utility model is a metal frame with an anti-tipping function. In use, the positioning member 3 is inserted into the two slide rails 2, and then the abutment position is determined so that the through hole 21 on the slide rail 2 is aligned with the threaded groove 31 on the positioning member 3. The bolt 22 is passed through the through hole 21 and screwed into the threaded groove 31 to fix the positioning member 3. Then, the handwheel 84 is turned to drive the worm gear 83 to rotate. The rotation of the worm gear 83 can cause the worm wheel 82 meshing with it to drive the screw 81 to rotate. When the screw 81 rotates, it can cause the support cylinder 6 threaded to it to move the support plate 7 upward, so that the support plate 7 is tightly against the ceiling. When the metal frame 1 tilts, it will change its angle. With the support plate 7 tightly against the ceiling, the metal frame 1 does not have the space to tilt, thereby achieving the purpose of preventing the metal frame 1 from tilting and ensuring the safety of the metal frame 1 during use.
