[0026] In order to make the above objectives, characteristics and advantages of the utility model more apparent and comprehensible, the specific embodiments of the utility model will be described in detail below with reference to the accompanying drawings.

[0027] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from the description, and the person skilled in the art can make similar generalization without departing from the connotation of the utility model, therefore the utility model is not limited by the specific embodiments disclosed below.

[0028] Secondly, the "one embodiment" or "embodiment" referred to here means that the specific features, structures or characteristics can be included in at least one implementation of the utility model. In this specification, "in one embodiment" does not mean the same embodiment, nor is it an independent or alternative embodiment that excludes other embodiments.

[0029] Embodiment 1, refer to Figs. 1-4This is the first embodiment of the present invention, which provides a correction mechanism including an installation component 100, a packaging installation sleeve 101, and an installation bolt 102 threaded inside the installation sleeve 101, with the upper part of the installation bolt 102 penetrating through the installation sleeve 101. When placing the installation bolt 102, the installation sleeve 101 is first threaded onto the outside of the installation bolt 102. Then, concrete is poured onto the installation surface to enclose the installation bolt 102 and the installation sleeve 101, leaving the upper end of the installation bolt 102 exposed to prevent contamination by concrete and subsequent installation. The correction component 200 includes a correction sleeve 201 fitted onto the exposed end of the installation bolt 102. The correction sleeve 201 facilitates the handling of displaced installation bolts 102 by workers, ensuring the normal installation of external equipment.

[0030] Furthermore, the upper end of the correcting sleeve 201 is provided with an extension screw 202 for installing external equipment, and the end of the correcting sleeve 201 away from the extension screw 202 is provided with a correcting screw groove 203 that is threadedly connected to the mounting bolt 102. After the concrete is poured, due to gravity, the internal water and heavier particles will settle downwards, resulting in a higher surface moisture content. This causes volume shrinkage after water evaporation, which in turn causes the mounting bolt 102, which is poured with it, to settle downwards. This results in the mounting bolt 102 being lower than the standard height, thus affecting the installation of external equipment. In this embodiment, the extension screw 202 is used to supplement the height of the settled mounting bolt 102. Finally, the portion of the extension screw 202 that exceeds the standard is cut off as required, ensuring the installation accuracy of the anchor bolts and facilitating the installation of external equipment.

[0031] Furthermore, the correcting screw groove 203 and the extension screw 202 are concentrically arranged. The concentric design of the correcting screw groove 203 and the extension screw 202 ensures that the axis of the extension screw 202 is aligned with the axis of the mounting bolt 102 installed in the correcting screw groove 203, thus preventing misalignment during the installation of external equipment.

[0032] In use, by correcting the threaded connection between the sleeve 201 and the mounting bolt 102, the extension screw 202 is installed together with the mounting bolt 102. This can supplement the height of the mounting bolt 102 that has settled, ensuring the installation accuracy of the anchor bolt and facilitating the installation of external equipment.

[0033] Example 2, refer to Figs. 1-4This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a correcting screw groove 203 and an extension screw 202 with an eccentric arrangement. Uncured concrete has a high internal moisture content and is prone to flowing to lower-lying areas under gravity, which can cause the mounting bolts 102 located in the concrete to shift to the side, affecting the installation of external equipment. In this embodiment, the eccentric arrangement of the correcting screw groove 203 and the extension screw 202 ensures that the axis of the extension screw 202, located on the correcting sleeve 201, is in the correct position. Fig. 4 As shown, this reduces the impact of mounting bolt 102 offset on equipment installation.

[0034] Furthermore, a fastening nut 300 is threaded onto the extension screw 202. When installing external equipment, it is generally connected to the equipment via the threads on the extension screw 202. In this embodiment, by rotating the fastening nut 300, the mounting surfaces between the equipment and the extension screw 202 can be compressed, thereby improving installation stability.

[0035] Furthermore, a dustproof mesh cylinder 400 is slidably sleeved on the outside of the extension screw 202. The dustproof mesh cylinder 400 sleeved on the outside of the extension screw 202 can protect the extension screw 202 during transportation, prevent it from being damaged by debris during transportation, and improve the protective performance of its surface threads.

[0036] In use, by correcting the eccentric setting of the screw groove 203 and the extension screw 202, the extension screw 202 set on the correcting sleeve 201 is positioned correctly when the mounting bolt 102 is offset, reducing the impact of the mounting bolt 102 offset on the equipment installation. In addition, the dustproof screen 400 can protect the extension screw 202 from damage by debris during transportation and improve the protective performance of its surface threads.

[0037] Example 3, referring to Figs. 5-6 This is the third embodiment of the present invention, which further provides a direct-buried anchor bolt. A connecting plate 500 is disposed between the mounting sleeve 101 and the correcting sleeve 201, with both ends of the connecting plate 500 fixedly connected to the mounting sleeve 101 and the correcting sleeve 201, respectively. When the external equipment moves, it may shake, potentially causing the extension screw 202 connected to it to loosen, thus affecting the installation stability of the equipment. In this embodiment, the connecting plate 500 connects the mounting sleeve 101 and the correcting sleeve 201 together. Because the mounting sleeve 101 is fixed to the mounting surface under the action of concrete, and because the correcting sleeve 201 is connected to the mounting sleeve 101 via the connecting plate 500, the correcting sleeve 201 is less likely to loosen under external force, thereby ensuring the installation stability of the external equipment.

[0038] Furthermore, the two ends of the connecting plate 500 are respectively fixed to the mounting sleeve 101 and the correcting sleeve 201 by spot welding. Spot welding is a resistance welding method that assembles the workpieces into a lap joint and presses them between two electrodes, using resistance heat to melt the base metal and form a weld point. Because spot welding is simple to operate and can form a high-strength weld joint, it meets the structural strength requirements between the correcting sleeve 201 and the mounting sleeve 101.

[0039] Furthermore, the cross-section of the connecting plate 500 is rectangular.

[0040] In use, the mounting sleeve 101 and the correcting sleeve 201 can be connected together by the connecting plate 500. Since the correcting sleeve 201 is connected to the mounting sleeve 101 by the connecting plate 500, the correcting sleeve 201 is not easy to loosen under the action of external force, thus ensuring the installation stability of the external equipment.

[0041] Example 4, refer to Figs. 5-6 This is the third embodiment of the present invention, which further provides a direct-buried anchor bolt. It includes a connecting plate 500 with a bent cross-section. Depending on installation requirements, the installation specifications of the corresponding mounting sleeve 101 and the correcting sleeve 201 may not be consistent. Therefore, in this embodiment, a bent connecting plate 500 is provided to facilitate the connection between the correcting sleeve 201 and the mounting sleeve 101 of different specifications.

[0042] In use, the setting of the beveled connecting plate 500 reduces the difficulty of connecting the correction sleeve 201 of different specifications with the installation sleeve 101, thereby improving the practicality of the device.
