[0024] like Figure 1-4 As shown, a bridge anti-seismic support includes a base 1, a support connector 2 fixed to the base 1 and a wire groove 3 located on the upper part of the base 1, the wire groove 3 is fixed to the base 1 through a fixing device 4, the interior of the base 1 is a accommodating space with an upper opening, the fixing device 4 is located in the accommodating space of the base 1 and includes a side plate 41 and a distance adjustment mechanism, the number of the side plates 41 is two and they are relatively arranged at the upper opening of the base 1, the distance adjustment mechanism is used to adjust the distance between the side plates 41, the distance adjustment mechanism includes a screw rod 42, a screw sleeve 43, a fixing rod 44 and a rotating component, the screw rod 42 is horizontally rotatably connected in the base 1, the number of the screw sleeve 43 is two and they are relatively screwed on the screw rod 42, one end of the fixing rod 44 is fixed to the screw sleeve 43, and the other end passes through the opening of the base 1 and extends and is fixed to the corresponding side plate 41, and the rotating component is used to drive the screw rod 42 to rotate.
[0025] In this embodiment, the rotation of the screw rod 42 driven by the rotating component can make the screw sleeves 43 relatively arranged on the screw rod 42 approach each other, and make the side plates 41 fixed by the fixing rod 44 and the screw sleeve 43 approach each other, so that the wire groove 3 can be fixed. Therefore, it is only necessary to rotate the rotating component to drive the movement of the screw rod 42 and the screw sleeve 43 to make the side plates 41 approach each other to achieve the purpose of fixing the wire groove 3. There is no need to use connecting components and tools to achieve the fixing purpose, so the disassembly and assembly are relatively convenient and quick.
[0026] Specifically, the rotating component includes a gear 45 , a rack 46 , a knob 47 and a reset member. The gear 45 is coaxially fixed to the screw 42 . The rack 46 meshes with the gear 45 and one end of the rack penetrates the wall of the base 1 and extends to be fixed to the knob 47 . The reset member is fixed to the rack 46 .
[0027] In this embodiment, by pulling the knob 47 at one end of the rack 46, the rack 46 can be driven to move backward, thereby driving the gear 45 meshing with the rack 46 to rotate, so that the screw 42 can rotate the side plate 41 to move backward, and then the wire groove 3 can be placed in and the knob 47 can be released. Therefore, the fixing process only needs to pull the knob 47, and the reset member serves to reset the rack 46 so that the side plate 41 clamps the wire groove 3.

[0029] In this embodiment, the rack 46 and the gear 45 are used and reset by the reset member. Compared with other methods of only rotating the screw 42, the screw 42 can be rotated without being affected by vibration and other conditions, so it is more stable.
[0030] Specifically, a plurality of slots 7 are evenly distributed on the side panels 41 from top to bottom, a crossbeam 5 is provided between two side panels 41 , two ends of the crossbeam 5 respectively penetrate the slots 7 on the corresponding side panels 41 , and a limiting block 6 is provided on the surface of the crossbeam 5 at the side panel 41 .
[0031] In this embodiment, when the side plates 41 move backward, the cross beam 5 is inserted into the slot 7 from between the side plates 41 , and the purpose of vertically fixing the wire groove 3 is achieved through the limiting of the limiting block 6 .

Therefore, it is only necessary to rotate the rotating component to drive the movement of the screw rod 42 and the screw sleeve 43 to make the side plates 41 approach each other to achieve the purpose of fixing the wire groove 3. There is no need to use connecting components and tools to achieve the fixing purpose, so the disassembly and assembly is relatively convenient and quick.
