Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical processing and manufacturing, and particularly relates to a bracket structure for fixing a vacuum interrupter. Background Art

[0002] The vacuum interrupter is a core component of medium and high voltage power switches. It is used to extinguish arcs in high voltage electrical equipment. Through the excellent insulation of the vacuum inside the tube, it can quickly extinguish arcs and suppress current after the medium and high voltage circuits are cut off from power, thus avoiding accidents and incidents.

[0003] The subsequent processing process of the vacuum interrupter is: cleaning the surface of the vacuum interrupter - brushing the adhesive - coating the vacuum interrupter with silicone rubber. The surface cleaning process of the interrupter is an important process, which will affect the bonding strength between the silicone rubber and the ceramic and metal, and thus affect the insulation performance of the vacuum interrupter.

[0004] After the vacuum interrupter is cleaned, the module must be inverted before the next step. The existing production process is machine cleaning, and the current operation is manual inversion and fixation of the vacuum interrupter assembly module. When a vacuum interrupter with a more complex module and a larger weight and volume appears, not only can it not be installed quickly, it requires physical effort and a long time, and there is also a risk of contaminating the surface of the vacuum interrupter, affecting processing efficiency. Utility Model Content

[0005] The purpose of the utility model is to provide a bracket structure for fixing a vacuum interrupter, so as to overcome the problems of low processing efficiency and easy contamination when manually inverting the vacuum interrupter assembly module in the prior art.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A bracket structure for fixing a vacuum interrupter comprises a base, wherein the base comprises a base plate and a base bracket, the base bracket is mounted on one side of the base plate, at least one bayonet is provided on the base plate, a gasket is installed in the bayonet, an opening is provided on the gasket, and the gasket is removable.

[0008] Furthermore, the length of the gasket is smaller than the length of the bayonet.

[0009] Furthermore, the edge of the bayonet on the base plate is a stepped structure.

[0010] Furthermore, a detachable structure is adopted between the base plate and the base bracket.

[0011] Furthermore, the base plate is a square structure, and there are four base brackets, and a base bracket is installed at each of the four corner structures of the base plate.

[0012] Furthermore, one end of the bayonet is arranged at the edge of the base plate.

[0013] Furthermore, the spacing at the bayonet opening is smaller than the spacing inside the bayonet.

[0014] Furthermore, there are two bayonet openings on the base plate.

[0015] Furthermore, the opening directions of the two bayonet holes are the same.

[0016] Furthermore, the bayonet on the base plate and the opening on the gasket are chamfered.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] The utility model provides a bracket structure for fixing a vacuum interrupter, comprising a gasket for fixing an inverted vacuum interrupter, wherein the gasket is embedded in a bayonet, and an opening is provided on a base plate. By assembling the gasket in a groove provided on the base plate, the vacuum interrupter is inverted on the gasket, and then assembling a module, the module can be assembled quickly and efficiently without contaminating the surface of the vacuum interrupter. At the same time, the detachable relationship between the gasket and the bayonet not only can the vacuum interrupter be firmly fixed, but also the detachability of the gasket facilitates maintenance or replacement of different types of vacuum interrupters.

[0019] Preferably, the length of the gasket is smaller than the length of the bayonet, ensuring that the gasket will not completely fill the bayonet during installation, providing space for disassembly of the gasket, and also ensuring the stability and flexibility of the gasket in the bayonet.

[0020] Preferably, the base and the base bracket are made into a detachable structure, which makes it easy to disassemble and reassemble the base plate and the base bracket when needed, and facilitates maintenance and replacement.

[0021] Preferably, the spacing at the bayonet opening is smaller than the spacing inside the bayonet, which helps to better fix the gasket and prevent the gasket from loosening or falling off during the installation process. BRIEF DESCRIPTION OF THE DRAWINGS
