Description

Technical Field

[0001] The utility model relates to the technical field of electron guns, in particular to an electron gun mechanism capable of quickly replacing a filament. Background Art

[0002] An electron gun is a device that generates an electron beam. Electron guns are widely used in many fields, such as televisions, computer monitors, medical equipment, semiconductor manufacturing, etc. The main function of an electron gun is to convert electrical energy into a high-speed moving electron beam to achieve various applications. The development of electron guns originated from radio technology, which generates current by heating the cathode in a vacuum, and then generates an electron beam by accelerating the electron flow between the electrode and the anode. This primitive electron gun is called a cathode ray tube, which is one of the earliest forms of electron guns.

[0003] The prior art also has the following defects during use:

[0004] 1. In the electron gun in the prior art, the filament is a device for generating an electron beam. The filament is one of the most important components in the electron gun. The filament plays a role in heating and generating an electron beam in the electron gun. However, due to the limitations of the material and structure of the filament, the service life of the filament is usually short and needs to be replaced regularly. Replacing the filament once will waste a lot of time;

[0005] 2. In the electron gun in the prior art, the filament needs to be replaced regularly during operation, so a faster way of replacing the filament is needed. By replacing the filament, the electron gun can stably generate an electron beam. In the process of replacing the filament, other parts need to be replaced, and replacing other parts will waste a lot of time, so the replacement speed of other parts needs to be optimized.

[0006] In view of this, we propose an electron gun mechanism that can quickly replace the filament to solve the existing problem. Utility Model Content

[0007] The utility model aims to provide an electron gun mechanism capable of quickly replacing a filament, so as to solve the problems raised in the above-mentioned background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electron gun mechanism capable of quickly replacing a filament, comprising a gun head and a filament, a ceramic column being installed on the top of the gun head, a first fixing block being installed on the bottom of the gun head, a filament being installed on the top of the first fixing block, a clamping ring being installed inside the first fixing block, a clamping groove being provided inside the clamping ring, a third clamping head being installed inside the clamping groove, a second fixing block being installed at the bottom of the first fixing block, a first clamping head being installed at the bottom of the gun head, a mounting frame being installed at the bottom of the first clamping head, an elastic card being installed on the inner side of the mounting frame, a second clamping head being installed on the top of the elastic card, and a threaded hole being provided on the side of the mounting frame.

[0012] Preferably, a first bolt is installed on a side surface of the first fixing block.

[0013] Preferably, a ceramic pad is installed on the side of the gun head close to the ceramic column.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. The utility model designs a filament structure for quick installation and disassembly. The main material of the filament is tungsten filament. The filament plays the role of heating and generating electron beam in the electron gun. Due to the limitation of the material and structure of the filament, the service life of the filament is usually short and needs to be replaced regularly. The filament structure can be replaced quickly, thereby improving work efficiency.

[0016] 2. The utility model designs a mounting frame to facilitate the rapid installation and removal of the gun head, so as to facilitate the rapid replacement of the filament, thereby improving the work efficiency of replacing parts. The main material of the filament is tungsten wire, which has a very high melting point and can withstand radiation damage under high temperature, thereby ensuring the stability and life of the filament.
