Abstract
The utility model provides a mercury gun of a round exhaust machine, which comprises a gun body, a mercury cup arranged at the lower end of the gun body, a mercury particle plug engaged with the mercury cup, a round bar arranged in the central position of the gun body, and a cylindrical hole formed at the middle of the round bar, wherein the upper end surface of the cylindrical hole is communicated with the upper end surface of the round bar, the lower end surface of the cylindrical hole and the lower end surface of the round bar keep a certain distance, the lower end surface of the round bar extends to the inside of the gun body, a side surface hole is formed on the round bar in the position below the lower end surface of the cylindrical hole inside the round bar and communicated with the cylindrical hole, and a radial seal device is arranged on the outer surface of the round bar. With the structure, the mercury gun of the round exhaust machine can meet the requirements for seal performance without the need to be cleaned during the exhaust process, thereby ensuring consistency in product quality.
Description
[technical field]
The utility model relates to a kind of production equipment of fluorescent lamp product, specifically is meant a kind of employed round exhaust machine mercury of production equipment rifle of fluorescent lamp product.
[background technology]
Round exhaust machine is a kind of automated production equipment of fluorescent lamp product, it can be finished exhaust to fluorescent tube, drips mercury on an equipment, energising is decomposed, butt joint, towards operations such as argons.Circumferential edges at the work disk of round exhaust machine evenly is provided with a plurality of mercury rifles, and round exhaust machine mercury rifle is the important component part of round exhaust machine, and it is bearing exhaust, drip important production process such as mercury.
In round exhaust machine rotation process intermittently, each station mercury rifle all annotating the mercury position, requires it to open mercury rifle seal cover, injects the mercury grain, and then sealing.This hermetically-sealed construction is to establish a corresponding end cap at mercury rifle one end face, be provided with an O RunddichtringO between end face and the end cap, and end cap is provided with the end cap holddown spring.The mercury rifle of this structure, in each process of injecting the mercury grain, end cap all will be opened, the action of closure, because there are impurity material such as dust in the environment of round exhaust machine work, therefore, the course of work requires often to clean sealing ring, otherwise the phenomenon that can leak air.For to the exigent fluorescent lamp product of vacuum, its product quality consistency is difficult to be guaranteed, and on-the-spot cleaning process accordance is also very rare to guaranteeing.Therefore, how to improve at present this in exhaust process, constantly dependence and on-the-spotly clean sealing ring and unmanageable technology obtains seal request, guarantee that the consistency of product quality has significance.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of round exhaust machine mercury rifle of new structure, and the mercury rifle of this structure does not need to clean in the process of exhaust, guarantees the requirement of mercury rifle sealing, guarantees the consistency of product quality.
The utility model solves the problems of the technologies described above by the following technical solutions:
A kind of round exhaust machine mercury rifle, comprise the rifle body, rifle body lower end has the mercury cup, the mercury grain plug that matches with the mercury cup is established a circular pin in rifle body centre, and the centre of circular pin is provided with a cylindrical hole, the upper surface of cylindrical hole communicates with the upper surface of circular pin, the lower surface of lower surface and circular pin is in the position of certain distance, and the lower surface of circular pin is stretched in the described rifle body, and the below of circular pin position, cylindrical hole lower surface within it is provided with a lateral aperture that communicates with cylindrical hole; The outer surface of described circular pin is provided with an apex combustion seal.
Described apex combustion seal comprises spring, nut, briquetting, thrust ball bearing, compressing tablet, sealing ring, the catch that is provided with successively from top to bottom.
Advantage of the present utility model is: in the round exhaust machine course of work, when the mercury rifle arrives notes mercury position, annotate mercury mechanism circular pin to pressing down, till the lateral aperture of circular pin is lower than the position of sealing ring, the mercury grain of notes mercury mechanism enters in the mercury rifle from cylindrical hole, the lateral aperture of circular pin, when annotating mercury mechanism return, circular pin upwards resets under the effect of spring, and the lateral aperture position of circular pin is higher than the position of sealing ring at this moment.The downward crush seal circle of nut body rotation nut produces radial deformation, reaches the effect of sealing.The round exhaust machine mercury rifle of this structure does not need to clean in exhaust process, guarantees the requirement of sealing, has guaranteed the consistency of product quality.
[description of drawings]
The utility model will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the utility model operating state one structural representation.
Fig. 2 is the utility model operating state two structural representations.
[embodiment]
Please consult illustrated in figures 1 and 2 simultaneously, a kind of round exhaust machine mercury rifle, comprise rifle body 1, rifle body 1 lower end has mercury cup 2, the mercury grain plug 3 that matches with mercury cup 2, establish a circular pin 4 in rifle body 1 centre, the centre of circular pin 4 is provided with a cylindrical hole 5, the upper surface of cylindrical hole 5 communicates with the upper surface of circular pin 4, the lower surface of lower surface and circular pin 4 is in the position of certain distance, the lower surface of circular pin 4 is stretched in the described rifle body 1, and the below of circular pin 4 position, cylindrical hole 5 lower surface within it is provided with a lateral aperture 51 that communicates with cylindrical hole 5; The outer surface of described circular pin 4 is provided with an apex combustion seal 6.
Described apex combustion seal 6 comprises spring 61, nut 62, briquetting 63, thrust ball bearing 64, compressing tablet 65, sealing ring 66, the catch 67 that is provided with successively from top to bottom.
In the round exhaust machine course of work, when the mercury rifle arrives notes mercury position, annotate mercury mechanism circular pin 4 to pressing down, till the lateral aperture 51 of circular pin 4 is lower than the position of sealing ring 65, the mercury grain of notes mercury mechanism enters in the mercury rifle from cylindrical hole 5, the lateral aperture 51 of circular pin 4, when annotating mercury mechanism return, circular pin 4 upwards resets under 61 effects of spring, and lateral aperture 51 positions of circular pin 4 are higher than the position of sealing ring 65 at this moment.The downward crush seal circle 65 of nut body rotation nut produces radial deformation, reaches the effect of sealing.The round exhaust machine mercury rifle of this structure does not need to clean in exhaust process, guarantees the requirement of sealing, has guaranteed the consistency of product quality.
