Embodiment Construction

[0027] Below in conjunction with accompanying drawing, its structure and working process are described to the implementation of the present invention:

[0028] see Figure 1 to Figure 6 As shown, the metal halide pill injection device of the present invention can be used for the preservation of the metal halide pill 401 , which includes a metal halide pill injection device main body 1 , a stepping motor assembly 3 and an argon gas connector 4 for filling and protection.

[0029] The structure of the filling and protection argon joint 4 includes a self-sealing plug 108, which is threadedly connected with a articulated ferrule fitting 110, and the other end of the ferrule fitting 110 is connected with an intake copper pipe 109 to protect the argon gas from the copper pipe. 109 air intake, when the self-sealing plug 108 was pulled out from the intake self-sealing valve body 210, the one-way valve in the self-sealing plug 108 automatically closed the argon gas.

[0030] The stepp...

Abstract

The invention discloses a metal halide pill injecting device comprising a main body of the metal halide pill injecting device and a stepping motor component connected with the main body of the metal halide pill injecting device. The stepping motor component is provided with a fitting seat, a stepping motor arranged on the fitting seat, a pinion wheel arranged on the stepping motor and a hand-screw bolt arranged on the fitting seat; the main body of the metal halide pill injecting device is provided with a base, a screw hole arranged on the base and connected with the hand-screw bolt, a main gear arranged on the base and jogged with the pinion wheel, an outer cylinder connected with the base, an outer cylinder cover covering the outer cylinder and an air inflow self-sealing valve body arranged on the outer cylinder body. The metal halide pill injecting device is also provided with a protecting argon charging joint on which a self-sealing plug inserted into the air inflow self-sealing valve body is arranged. The metal halide pill injecting device is reliable and convenient to use.

Description

technical field [0001] The invention relates to a device for producing arc tubes of metal halide lamps, in particular to a metal halide pellet injector used for preserving metal halide pellets. Background technique [0002] At present, the domestic lamp industry, especially the production of arc tubes for metal halide lamps, needs to add metal halide pills, which are referred to as metal halide pills. Metal halide pills are very hygroscopic and will deliquesce and deteriorate in a few seconds in the air. , cannot be used, so the preservation, addition, and injection of metal halide pills into the arc tube must be carried out under the protection of high-purity argon gas. In the prior art, the metal halide pellets are injected in the glove box, which is inconvenient for production; there is also a very simple utensil to manually inject the metal halide pellets, which will cause the metal halide pellets to be polluted and affect the quality of the lamp. [0003] Therefore be ...
