Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a transformer spring shock absorber. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil and the iron core. The main functions of the transformer are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization, etc. According to their uses, they can be divided into: power transformers and special transformers. Transformers are basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban communities and other fields. When installing the transformer, it is necessary to install a spring shock absorber on the transformer mounting base to reduce the looseness of the installation position caused by the vibration of the transformer.

[0003] In order to improve the shock absorbing effect of the shock absorber on the transformer, the prior art has made many improvements to the transformer spring shock absorber. For example, the patent with patent publication number CN219388505U discloses a shock absorber for a transformer, including a bottom plate, a square tube is symmetrically installed on the top of the bottom plate, a fixing plate is installed on the top of the square tube, and a guide sleeve is symmetrically arranged on one side of the top of the fixing plate, and left and right fixing bolts are arranged on the inner side of the guide sleeve, and an upper pressure plate is commonly threadedly installed at one end of the four fixing bolts, and a bolt 2 is rotatably installed at the middle part of the bottom end of the upper pressure plate, and a lower pressure plate is threadedly installed at the lower end of the outer wall of the bolt 2. The utility model is a shock absorber for a transformer. Since the design adopts the design of two damping springs, the vibration force can be transmitted downward through the upper pressure plate, and the downward movement of the bolt 2 and the lower pressure plate can be used to generate an extrusion force on the damping spring. At the same time, the fixing bolt is used to slide along the inner side of the guide sleeve to achieve the reduction of the vibration force. Moreover, the two damping springs can provide a larger elastic supporting force, which greatly improves the upper bearing capacity and shock absorbing effect.

[0004] The above patent has obvious beneficial effects, but still has the following shortcomings in actual operation:

[0005] When the prior art needs to install a transformer, at least four transformer shock absorbers such as those in the above-mentioned comparative documents need to be installed at the transformer installation position, and the position of each transformer shock absorber needs to be determined. However, in reality, the sizes of transformers are different, so the position of the shock absorber needs to be measured and fixed each time it is installed. If an error occurs during measurement, the shock absorber needs to be reinstalled, which reduces the installation efficiency of the transformer spring shock absorber. Therefore, there is an urgent need in this field to improve the transformer spring shock absorber to solve the defects of the prior art. Utility Model Content
