[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below 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, rather than all the embodiments.

[0024] Example 1: Reference Figure 1-Figure 4 A convenient temporary fixing device for vertical ribs on aluminum formwork exterior walls, used in the field of building formwork technology, includes a rib body consisting of a main rib 1 and two secondary ribs 2. A trough 3 is designed within the main rib 1 to store and accommodate the two secondary ribs 2. When the main rib 1 needs to be extended, the two secondary ribs 2 can slide out of the trough 3 and unfold.

[0025] To achieve the extension and retraction of the secondary back ribs 2, an adjustment assembly is provided within the main back rib 1. The adjustment assembly comprises a first groove 4 and a second groove 5 defined within the main back rib 1, both of which are connected to the receiving groove 3. One end of each secondary back rib 2 slides within the first groove 4, and the other end slides within the second groove 5. A bidirectional screw 6 is rotatably mounted within the second groove 5. The two secondary back ribs 2 are threadedly connected to the forward and reverse bolt sections on the circumferential surface of the bidirectional screw 6. By rotating the bidirectional screw 6, the two secondary back ribs 2 can be driven to move simultaneously in opposite or same directions, thereby achieving extension or retraction.

[0026] To facilitate the rotation of the bidirectional screw 6, the device also features a self-locking drive assembly. This assembly comprises a worm wheel 7 fixed to the surface of the bidirectional screw 6, and a worm 8 rotatably mounted within the second groove 5 and meshing with the worm wheel 7. Rotation of the worm 8 drives the worm wheel 7 and the bidirectional screw 6 to rotate together. The worm gear mechanism has a self-locking function. When the worm 8 stops rotating, the bidirectional screw 6 and the secondary back rib 2 remain in their current position, thus temporarily securing the device.

[0027] In order to facilitate the operation of the worm 8, the self-locking drive assembly further includes a rotating rod 10. The worm 8 moves outward and penetrates the side end of the main back rib 1, and the rotating rod 10 is fixed to the side end of the worm 8. By rotating the rotating rod 10, the worm 8 can be easily driven to rotate.

[0028] Example 2: Reference Figure 1-Figure 4 , based on the improvement of Example 1: In order to prevent the secondary back ribs 2 from releasing the squeeze of the worm gear 7 during movement, this device also fixes two limit plates 9 on the surface of the bidirectional screw 6. These two limit plates 9 are respectively arranged on the upper and lower sides of the worm gear 7 to limit the position of the two secondary back ribs 2.

[0029] This device also considers the contact between the back ribs and the aluminum mold. A first connecting gap 101 is defined within the main back rib 1, and a second connecting gap 201 is defined within each of the two secondary back ribs 2. When the secondary back ribs 2 are fully extended, the first connecting gap 101 and the two second connecting gaps 201 align, forming a complete gap structure. Furthermore, the main back rib 1 and the two secondary back ribs 2 are kept horizontal at their ends near the aluminum mold to ensure close contact with the mold.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
