DETAILED DESCRIPTION

[0026] The specific embodiment of the utility model is further described in detail in combination with the drawings, so that the technical scheme of the utility model is more easily understood and mastered.

[0027] A deviation-correcting and liftable isolation rubber support, comprising a rubber body 1, an upper fixed plate 11 and a lower fixed plate 12.

[0028] The base plate 22 is fixed on the ground or foundation. The fence plate 21 is fixed on the base plate 22, and the fence plate 21 is a square frame. The lower fixing plate 12 is located in the fence plate 21 and is placed on the base plate 22. In order to make the fixing plate move more smoothly on the base plate 22, a sliding plate 23 is arranged between the lower fixing plate 12 and the base plate 22, the sliding plate 23 is fixed on the base plate 22, and the lower fixing plate 12 is placed on the base plate 22. The sliding plate 23 is a polytetrafluoroethylene plate.

[0029] A tension plate 3 for abutting against the lower fixing plate 12 is fixedly connected to the side of the fence plate 21 away from the base plate 22 by bolts 31, and the tension plate 3 has four and is located at the four corners of the fence plate 21 respectively. There is a lifting gap between the tension plate 3 and the lower fixing plate 12.

[0030] Threaded holes 4 are formed in the side wall of the fence plate 21, and adjusting bolts 41 for abutting against the side wall of the lower fixing plate 12 are threadedly connected to the threaded holes 4, and a plurality of adjusting bolts 41 are arranged around the lower fixing plate 12.

[0031] A placing inclined surface 32 is formed on the tension plate 3, and the placing inclined surface 32 faces the rubber body 1, so that the rubber body 1 is not easy to contact the tension plate 3 and is not easy to be damaged.

[0032] A limiting structure 5 for limiting the one-way rotation of the adjusting bolt 41 is arranged on the fence plate 21. The limiting structure 5 includes a mounting recess 51, a ratchet wheel 52, a clamping plate 53 and a resilient member 54. The mounting recess 51 is formed on the inner wall of the fence plate 21. The ratchet wheel 52 is fixed to the adjusting bolt 41 and located in the mounting recess 51, and the ratchet wheel 52 is coaxially arranged with the adjusting bolt 41.

[0033] The clamping plate 53 is hinged to the inner wall of the mounting recess 51 by a pin shaft, and the end of the clamping plate 53 is used to abut against the ratchet wheel 52. The two ends of the resilient member 54 are fixedly connected with the inner wall of the mounting recess 51 and the clamping plate 53 respectively. The resilient member 54 is a spring.

[0034] The clamping plate 53 is connected with an extension section 6, and the extension section 6 is located at the end of the clamping plate 53 away from the ratchet wheel 52.

[0035] The extension section 6 is pressed to make the clamping plate 53 flip along the axis of the pin shaft, and the clamping plate 53 is separated from the ratchet wheel 52, so that the adjusting bolt 41 can be reversely rotated and separated from the lower fixing plate 12. The adjusting bolt 41 on the opposite side is positively rotated, the adjusting bolt 41 pushes the lower fixing plate 12 to move along the sliding plate 23, so that the rubber body 1 is corrected. Then all the adjusting bolts 41 are positively rotated and abut against the lower fixing plate 12.

[0036] When the adjusting bolt 41 is rotated clockwise, it moves along its own axis towards the lower fixed plate 12. Simultaneously, the ratchet 52 rotates. When the adjusting bolt 41 stops rotating, the elastic force of the elastic element 54 causes the locking plate 53 to engage with the ratchet 52. When the adjusting bolt 41 rotates counterclockwise, the locking plate 53 limits its rotation, thus achieving unidirectional rotation of the adjusting bolt 41. Under vibration, the adjusting bolt 41 is less likely to separate from the lower fixed plate 12.

[0037] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
