Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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.

[0028] Example 1, combined with Figure 1 Explanation:

[0029] An anti-seismic support foot fixing device includes: a base 1, a sliding plate 2, a left limiting component 3, a right limiting component 4, a rack 5, a gear 6, a connecting bracket 7, a rotating shaft 8, and a bearing seat 9.

[0030] The slide plate 2 is slidably mounted on the base 1, so that the slide plate 2 can move horizontally within the range of the base 1.

[0031] The left limiting component 3 is connected to the left side of the slide plate 2, and the right limiting component 4 is connected to the right side of the slide plate 2. The left limiting component 3 and the right limiting component 4 are used to position the slide plate 2.

[0032] The rack 5 is mounted on the slide plate 2, and the gear 6 meshes with the rack 5. The gear 6 is coaxially fixedly connected to the connecting bracket 7. The connecting bracket 7 can drive the gear 6 to rotate, thereby driving the slide plate 2 to move horizontally through the rack 5.

[0033] The connecting bracket 7 is rotatably mounted on the bearing seat 9 via the rotating shaft 8.

[0034] Example 2, based on Example 1, combined with... Figure 2 and Figure 3 Explanation:

[0035] The left limiting component 3 and the right limiting component 4 have the same structure. This configuration reduces production costs and complexity, and decreases the types of parts that need to be managed and the amount of inventory.

[0036] The left limiting component 3 includes: a left limiting screw component 31, a left screw mounting base 32, and a left slide plate mounting base 33. The left limiting screw component 31 is connected to the left screw mounting base 32 by threads. The left screw mounting base 32 is fixedly installed on the base 1, and the left slide plate mounting base 33 is fixedly installed on the slide plate 2. The end of the left limiting screw component 31 abuts against one side of the left slide plate mounting base 33.

[0037] The left limiting screw assembly 31 provides the main limiting force. By rotating the left limiting screw assembly 31, the distance between its end and the left slide plate mounting base 33 can be adjusted, thereby fixing the final position of the slide plate 2. The left screw mounting base 32 is fixed on the base 1 and provides a stable fulcrum for the left limiting screw assembly 31.

[0038] The right limiting component 4 includes: a right limiting screw component 41, a right screw mounting base 42, and a right slide plate mounting base 43. The right limiting screw component 41 is connected to the right screw mounting base 42 by threads. The right screw mounting base 42 is fixedly installed on the base 1. The right slide plate mounting base 43 is fixedly installed on the slide plate 2. The end of the right limiting screw component 41 abuts against one side of the right slide plate mounting base 43.

[0039] Example 3, based on Example 2, combined with Figure 4 Explanation:

[0040] The left limiting screw assembly 31 includes a threaded rod 311, a nut 312, and a large-diameter abutment block 313. The threaded rod 311 is threadedly connected to the left screw mounting base 32. One end of the threaded rod 311 is fixedly connected to the nut 312, and the other end of the threaded rod 311 abuts against the left slide plate mounting base 33 through the large-diameter abutment block 313. The large-diameter abutment block 313 is detachably connected to the threaded rod 311.

[0041] Rotating the nut 312 causes the threaded rod 311 to rotate within the left screw mounting base 32, thereby adjusting the limiting function. Using a large-diameter abutment block 313 instead of directly abutting the end of the threaded rod against the left slide plate mounting base 33 increases the contact area between them. Under the same limiting force, a larger contact area means lower pressure, which prevents the abutment block or slide plate mounting base from being dented or damaged during adjustment or under stress, thus improving the durability of the component.

[0042] The nut 312 has a cross groove on its outer side and anti-slip texture on its circumferential surface, making it easy to tighten the screw.

[0043] Example 4, based on Example 3, combined with Figure 5 and Figure 6 Explanation:

[0044] Two sets of gears 6 and racks 5 are provided. The two sets of gears 6 are fixedly installed on both sides of the connecting bracket 7, and the two sets of racks 5 are fixedly connected to the slide plate 2 and mesh with the gears 6. The dual-gear drive can balance the driving force on both sides of the connecting bracket 7, reducing the possibility of tilting or excessive force on one side of the slide plate 2 during movement.

[0045] The base 1 and the slide plate 2 are slidably connected by a guide bar 11. The guide bar 11 provides a precise guiding path, and if the guide bar 11 is severely worn, it can be relatively easily disassembled and replaced without replacing the entire base or slide plate, thus reducing maintenance costs.

[0046] The working principle of this utility model is as follows: the rotating connecting bracket 7 drives the gear 6 to rotate, and the gear 6 then drives the slide plate 2 to slide on the base 1 through the meshing rack 5. When the slide plate moves to the target position, the left limiting component 3 and the right limiting component 4 are adjusted to press against the base 1, thereby locking the position of the slide plate 2 and realizing the fixation and precise positioning of the foot of the anti-vibration bracket. The gear and rack mechanism provides precise displacement control, while the limiting components provide the final rigid constraint. This utility model has a reasonable structure and is easy to use. It can make the connecting bracket adjustable and fixed within a larger angle range and is suitable for various working scenarios.
