In specific implementation, the equipment shell 11 consists of an upper side plate, a lower side plate, a left side plate, a right side plate, a front side plate and a rear side plate, the guide disc 12 is simultaneously connected with the left side plate, the right side plate, the front side plate and the rear side plate in a sliding manner, the output rod 13 upwards passes through the upper side plate, the rack B24 is fixedly connected with a sliding block, the sliding block is arranged on a guide rail, and the guide rail is fixedly arranged on the rear side plate along the horizontal direction, so that the rack B24 is connected with the equipment shell 11 in a sliding manner; two mutually parallel fixed shafts 5 are fixedly arranged on the rear side plate along the direction perpendicular to the rear side plate, and the first damping gear 31 and the second damping gear 32 are respectively arranged on the two fixed shafts 5 by adopting two rolling bearings, so that the rotation installation of the first damping gear 31 and the second damping gear 32 is realized. The return spring A25 is used for resetting the rack B24 on the one hand and generating translational rigidity on the rack B24 on the other hand; the return spring B26 is used for resetting the rack a21 in the vertical direction, and for generating lifting stiffness for the rack a 21; when the output rod 13 is connected with the vibration-isolated equipment, the vibration isolator and the vibration-isolated equipment form a vibration isolation system with rigidity and damping, so that vibration isolation protection of the vibration-isolated equipment is realized.
Referring to fig. 1 and 3, during a first displacement interval of the left-right translation of the rack B24, the second damping gear 32 is disengaged from the rack B24, and the normal damping application assembly applies Chang Zuni force to the rotating first damping gear 31; in a second displacement interval of the left-right translation of the rack B24, the second damping gear 32 is meshed with the rack B24 for transmission, and the normal damping force is applied to the rotating first damping gear 31 and the second damping gear 32 by the normal damping applying assembly at the same time.
Preferably, the rack B24 is composed of a long rack, a short rack, and a rack body; the rack body is arranged on the equipment shell 11 in a sliding way, the long rack is fixedly arranged at the upper end of the rack body along the horizontal direction, and the short rack is fixedly arranged at the lower end of the rack body along the horizontal direction; the long rack is always meshed with the first damping gear 31 for transmission; in the first displacement interval, the short rack is disengaged from the second damper gear 32; in the second displacement interval, the short rack gear is meshed with the second damping gear 32. In specific implementation, the output rod 13 is connected with the vibration-isolated equipment, when the vibration-isolated equipment receives smaller impact force or vibration force with smaller amplitude, the lifting displacement of the output rod 13 and the rack A21 is smaller, and at the moment, the horizontal displacement of the rack B24 is also smaller, namely, the vibration-isolated equipment and the output rod 13 move in a lifting manner in a first displacement interval in the vertical direction, and correspondingly, the rack B24 moves horizontally in the first displacement interval in the horizontal direction; when the vibration isolation device receives a larger impact force or a larger vibration force with larger amplitude, the lifting displacement of the output rod 13 and the rack A21 is larger, and at the moment, the horizontal displacement of the rack B24 is larger, namely the vibration isolation device and the output rod 13 move in a second displacement interval in the vertical direction through a first displacement interval in the vertical direction, and correspondingly the rack B24 moves in a translation mode in the second displacement interval in the horizontal direction through the first displacement interval in the horizontal direction. In the first displacement interval, the damping force received by the vibration isolation equipment is a first damping force; in the second displacement interval, the damping force received by the vibration isolation equipment is a second damping force; since the rack B24 is simultaneously engaged with the first damper gear 31 and the second damper gear 32 in the second displacement interval, the second damper force is made larger than the first damper force.
Preferably, the number of the second damping gears 32 is two, and the two second damping gears 32 are symmetrically arranged at the left and right sides of the short rack. In particular, the first damping gear 31 may be provided in one or two, and when the number of the first damping gears 31 is two, the second damping force is about 1.5 times the first damping force; when the number of the first damping gears 31 is one, the second damping force is about twice the first damping force.

When the output rod 13 moves downwards, the guide disc 12 and the rack A21 are driven to move downwards, the reversing gear A22 meshed with the rack A21 rotates clockwise, and the reversing gear B23 rotates clockwise to drive the rack B24 to translate leftwards; when the output rod 13 moves upwards, the guide disc 12 and the rack A21 are driven to move upwards, the reversing gear A22 meshed with the rack A21 rotates anticlockwise, and the reversing gear B23 rotates anticlockwise to drive the rack B24 to translate rightwards; i.e. the lifting movement of the output rod 13 corresponds to a left-right translation of the rack B24. Since the meshing radius of the reversing gear a22 is smaller than that of the reversing gear B23, the horizontal displacement of the rack B24 is made larger than the lifting displacement of the rack a 21.
Referring to fig. 1 and 2, it is preferable that the constant damping applying assembly includes a connection rod a41 having one end fixedly installed on the apparatus housing 11, a connection rod B42 slidably connected to the connection rod a41, a friction block 44 fixedly installed on one end of the connection rod B42, and a pressing spring 43 having both ends fixedly connected to the connection rod a41 and the friction block 44, respectively, and always in a pressed state; the number of the constant damping applying members is equal to the sum of the numbers of the first damping gear 31 and the second damping gear 32; the friction block 44 abuts against the end face of the first damper gear 31 or the end face of the second damper gear 32 under the action of the pressing spring 43. In practice, if two second damping gears 32 and one first damping gear 31 are used, three constant damping applying assemblies need to be configured; if two second damper gears 32 and two first damper gears 31 are employed, four constant damping applying assemblies need to be provided. The friction block 44, the first damping gear 31 and the second damping gear 32 are made of materials which are not easy to wear, and the end face of the friction block 44 adjacent to the first damping gear 31 and the end face of the friction block 44 adjacent to the second damping gear 32 are all uneven so as to increase the friction coefficient and damping force. By adjusting the rigidity and the initial compression amount of the pressing spring 43, the positive pressure of the friction block 44 to the first damper gear 31 or the second damper gear 32 can be adjusted, thereby realizing control of the magnitude of the frictional damping force.
Preferably, a connecting plate 27 is fixedly arranged at the lower end of the rack A21, and two ends of the return spring B26 are fixedly connected with the equipment shell 11 and the connecting plate 27 respectively. The provision of the connection plate 27 can exert pressure on the return spring B26 better.
Referring to fig. 3, the relation between the kick damping force and displacement generated by the present invention is as follows: the vibration-isolated device and the output rod 13 are in the first displacement intervalDuring the inner lifting movement, the normal damping applying assembly generates a friction resistance to the rotating first damping gear 31, and the damping force applied by the vibration isolation device is constant +.>The method comprises the steps of carrying out a first treatment on the surface of the The vibration-isolated device and the output rod 13 are in the second displacement intervalAnd->During the internal lifting movement, the normal damping applying component generates friction resistance to the rotating first damping gear 31 and the rotating second damping gear 32, and the damping force applied by the vibration isolation device is constant as +.>。
The working principle of the invention is as follows: the vibration-isolated device connected to the output rod 13 is lifted and lowered by the external excitation, and the initial equilibrium position is set as zero point, and the downward movement is in the positive displacement direction for convenience of description. When the external excitation is small, the vibration-isolated equipment is in the first displacement intervalAn inner lifting movement; when the external excitation is large, the vibration-isolated device will be at the total zone consisting of the first displacement zone and the second displacement zone +.>And (5) inner lifting movement. The vibration-isolated device is in the first displacement zone +.>During the inner lifting movement, the rack A21 moves in a lifting manner, the reversing gear assembly drives the rack B24 to horizontally translate left and right, and further drives the first damping gear 31 to rotate, and at the moment, the second damping gear 32 is disengaged from the rack B24, so that the second damping gear 32 is static and does not rotate; the friction block 44 is abutted against the end face of the first damping gear 31 under the action of the pressing spring 43 and slides along the end face of the first damping gear 31, and the sliding friction force forms a first damping force +.>The method comprises the steps of carrying out a first treatment on the surface of the Is insulated by vibration isolation equipment>During the inner lifting movement, the rack B24 is meshed and driven with the first damping gear 31 and the second damping gear 32 at the left side; is insulated by vibration isolation equipment>During the inner lifting movement, the rack B24 is meshed and driven with the first damping gear 31 and the second damping gear 32 on the right side; therefore, when the vibration isolation device moves up and down in the second displacement interval, the rack B24 is simultaneously meshed with the first damping gear 31 and one of the second damping gears 32, the corresponding friction block 44 is abutted against the end face of the corresponding first damping gear 31 and the end face of the corresponding second damping gear 32 under the action of the pressing spring 43, and the sliding friction force forms a first damping force->。
