[0002] A ceramic vacuum tube is an electronic device that is a vacuum container made of glass or ceramic, which contains components such as electrodes, output coupling transformers and vacuum tubes.

[0003] Ceramic vacuum tube glaze spraying is a method of applying glaze to the surface of ceramic vacuum tubes by using a spray gun with the help of air pressure to disperse the glaze into uniform and fine droplets. Usually, the paint is evenly sprayed on the surface of the ceramic vacuum tube with a spray gun, and then the paint is dried and solidified to form a hard coating, which has the functions of protection, beauty and marking.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4The present embodiment provides a spray gun angle adjustment mechanism for spraying glaze on a ceramic vacuum tube, comprising a bracket 1 and a spray gun 6 for spraying glaze on the ceramic vacuum tube. The spray gun 6 is movably mounted below the bracket 1. An adjustment component for quickly adjusting the angle of the spray gun 6 is disposed on the outside of the bracket 1. The spray gun 6 uses air pressure to disperse the glaze into uniform and fine droplets, thereby achieving the purpose of spraying glaze on the outside of the ceramic vacuum tube.

[0021] The adjustment component includes a support tube 2 and a steering member 5, one end of the support tube 2 is fixedly connected to one side of the bracket 1, and the other end of the support tube 2 is fixedly installed with a mounting seat 4, the steering member 5 is rotatably installed in the inner cavity of the mounting seat 4, one end of the spray gun 6 is movably connected to the outer wall of the steering member 5, the steering member 5 is arranged to have a spherical structure, and the mounting seat 4 is arranged to have a hemispherical structure, wherein the steering member 5 is embedded in the interior of the mounting seat 4, and the steering member 5 can be rotated at will in the inner cavity of the mounting seat 4, thereby arbitrarily changing the angle between the spray gun 6 and the ceramic vacuum tube, thereby improving the degree of coverage and uniformity of the paint glaze on the outside of the ceramic vacuum tube, and reducing the adverse effects on the normal processing of the ceramic vacuum tube.

[0022] The mounting seat 4 is made of a rubber material with strong plastic deformation ability. The rubber material can increase the friction between the inner wall of the mounting seat 4 and the outer wall of the steering member 5, thereby increasing the stability of the steering member 5 in a stationary state and preventing the spray gun 6 from shaking when spraying glaze.

[0023] A connecting hose 3 is movably installed in the inner cavity of the support tube 2, and both ends of the connecting hose 3 extend to the outside of the support tube 2, and one end of the connecting hose 3 is connected to the inner cavity of the spray gun 6, and the other end of the connecting hose 3 is externally connected to a glaze storage box, wherein the outer wall of the support tube 2 is provided with two through holes connected to its own inner cavity, and the two ends of the connecting hose 3 are inserted to the outside of the support tube 2 through the two through holes. When the spray gun 6 rotates, the connecting hose 3 can move inside the support tube 2, preventing the connecting hose 3 from adversely affecting the angle adjustment of the spray gun 6.

[0024] The support tube 2 is set to an L-shaped structure, and the end of the support tube 2 away from the bracket 1 points to the ground. The ceramic vacuum tube is placed directly below the bracket 1. The glaze in the glaze storage box is transmitted to the spray gun 6 through the connecting hose 3, and then the spray gun 6 evenly sprays the glaze on the outside of the ceramic vacuum tube, thereby improving the convenience of spraying glaze on the ceramic vacuum tube.

[0025] A connecting plate 7 is fixedly installed on the end of the spray gun 6 away from the nozzle, and connecting ear plates 9 are symmetrically installed on both sides of the end of the connecting plate 7 away from the spray gun 6, and a positioning plate 8 is rotatably installed on the end of the connecting plate 7 away from the spray gun 6, one end of the positioning plate 8 is located between the two connecting ear plates 9, and the other end of the positioning plate 8 is fixedly connected to the outer wall of the steering member 5, and limiting disks 11 are fixedly installed on both sides of the positioning plate 8, and a receiving groove compatible with the limiting disk 11 is provided on the adjacent side of the two connecting ear plates 9, and the receiving groove is set to be a groove of the same shape as the limiting disk 11, and the receiving groove can provide space for the rotation of the limiting disk 11, so that the angle of the spray gun 6 can be adjusted again, so that the glaze spraying end of the spray gun 6 can always point to the ground, which is beneficial to spraying glaze on the outside of the ceramic vacuum tube.

[0026] A through hole is provided at the edge of the inner wall of the accommodating groove away from its own open end, and a positioning column 10 is installed in the inner cavity of the through hole. The outer wall of the positioning column 10 is provided with an external thread, and the inner wall of the through hole is provided with an internal thread matched with the external thread. By rotating the positioning column 10, one end of the positioning column 10 is tightly fitted with the edge of one end of the limit plate 11, the resistance of the limit plate 11 can be increased, thereby increasing the stability between the positioning plate 8 and the connecting plate 7 in a static state.
