Description

Technical Field

[0001] The utility model relates to the technical field of air spring vibration isolators, in particular to an adjustable air spring vibration isolator. Background Technique

[0002] The air spring shock absorber is a relatively new technology. Although its application is not very common yet, it is a very promising vibration isolation solution. It has been increasingly valued by people and is adopted in some engineering vibration isolations. An air spring is a rubber bladder reinforced by cords, filled with compressed air, and is a vibration damping rubber product that uses the compressibility of gas to act as a spring. There are types such as long pillow type, gourd type, and diaphragm type. In today's industrial and research fields, the requirements for the stability and vibration isolation performance of equipment are increasing. Especially in the fields of precision manufacturing, measurement, and acoustics, any tiny vibration may affect the quality of products or the accuracy of experiments.

[0003] In the existing technology, when adjusting the height of the whole air spring vibration isolator, it is time-consuming and laborious, so that the whole air spring vibration isolator cannot quickly adjust its height, resulting in the inability to adapt to different working environments or load conditions, thus reducing the operation flexibility and working efficiency of the equipment, and the practicability is not strong. Therefore, we propose an adjustable air spring vibration isolator to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable air spring vibration isolator to solve the problems raised in the above background technique.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

Rubber sealing plugs are movably inserted at both the upper and lower ends of the airbag. One mounting plates are fixedly installed on the sides of the two rubber sealing plugs away from each other. Two fixing plates are fixedly installed on the top of the second mounting plate. The same bidirectional screw is rotatably installed between the two fixing plates. A handwheel is fixedly installed on the right side of the bidirectional screw. Two driving blocks are threadedly connected to the outer side of the bidirectional screw. Two driving rods are hinged to the outer sides of the two driving blocks respectively. One fixing block is hinged to one side of the four driving rods. The top of the fixing block is fixedly installed at the bottom of the corresponding first mounting plate.

[0007] Preferably, a third fixing plate is fixedly installed on the outer side of the bidirectional screw. A plurality of insertion holes are formed on the outer side of the third fixing plate. A rectangular plate is fixedly installed on the right side of one of the fixing plates. A plug rod is slidably connected inside the rectangular plate. The bottom end of the plug rod is movably inserted into the corresponding insertion hole. A fixing ring is fixedly installed on the outer side of the plug rod. The top of the fixing ring is fixedly connected to a return spring. The top end of the return spring is fixedly connected to the bottom of the rectangular plate.

[0012] In the present utility model, for the adjustable air spring vibration isolator, by pulling the plug rod to drive the plug rod out of the inside of the insertion hole, the control of the bidirectional screw by the plug rod is lost. Then, by rotating the handwheel, the bidirectional screw is driven to rotate, so that the two driving blocks threadedly connected thereto start to move, thereby driving the driving rods rotatably connected thereto to start to rotate, and further driving the fixed block to move up and down, thereby driving the first mounting plate to move up and down, and further driving the entire device to move up and down. When the movement is completed, the plug rod is released, so that the plug rod fixes the bidirectional screw again. The whole process enables the entire device to quickly adjust the height, so as to quickly adapt to different working environments or load conditions, thereby improving the operation flexibility and working efficiency of the equipment, and having stronger practicability;

[0013] In the present utility model, for the adjustable air spring vibration isolator, by inserting two rubber sealing plugs into the upper and lower ends of the airbag, the second fixing plate and the first fixing plate are made to coincide, and then by turning the bolts, the first fixing plate and the second fixing plate are fixed, thereby realizing the sealing of the airbag;
