Abstract

The utility model discloses an ITO etcher swing injection exhaust pipe end cover structure comprising an end cover main body, wherein the section of the end cover main body is shaped like the Chinese character 'ao' ('ao' means concave in English); the bottom of the end cover main body is provided with a through hole; the inner side of the end cover main body is provided with threads; the aperture of the through hole is larger than the diameter of a cutting sleeve arranged on a rack pipe; the end cover main body is internally provided with two semicircular snap rings; the external diameter of the ring formed by the two semicircular snap rings is larger than the aperture of the through hole, and the inner diameter is smaller than the diameter of the cutting sleeve arranged on the rack pipe. For the end cover structure, the existing end cover structure is changed into a split structure, the through hole of the end cover main body is expanded so as to pass through the cutting sleeve arranged at the end part of the rack pipe, then the two semicircular snap rings are matched, and the end cover main body is clamped at the cutting sleeve through the two semicircular snap rings, thus enabling the rack pipe to be fixed on a liquid medicine header pipe. Therefore, when problems appear, the end cover can be replaced at any time, the rack pipe assembly and header pipe threads are better fixed, and liquid medicine can not be injected from the joint.

Description

ITO etching machine waves and sprays the comb end cover structure

Technical field

The utility model relates to a kind of ITO etching apparatus, and particularly a kind of ITO etching machine waves and sprays the comb end cover structure.

Background technology

ITO etching machine is one of special-purpose key equipment during PDP makes, and this equipment is to be used for processing on glass substrate ito transparent electrode, and this transparency electrode has direct influence to the luminous and vision quality of product.

As illustrated in fig. 1 and 2, existing ITO etching machine soup district wave spray comb adopt be enclosed within end cap main body 1 on the comb 3 earlier after, and then in comb 3 ends fixing on sealing-ring 6 and cutting ferrule 4, because the diameter of cutting ferrule 4 is greater than the aperture of end cap main body 1 through

hole

2,1 of end cap main body is enclosed within on the comb and can't takes off like this, by end cap with comb and total pipe coupling.

Yet existing end cap material of main part adopts polyethylene, and this equipment is in 50 ℃ Working environment in use, polyethylene easy embrittlement when this temperature, cause end cap to rupture, need to change end cap, still in the threaded connection place, because existing end cap main body is to be integrated on the comb assembly by the cutting ferrule that is fixed on the comb end, can't dismantle, causing when the end cap main body is damaged this equipment spare to change must be the replacing of whole comb assemblies, causes spare part cost height, stop time is long, often; And the design of existing end cover structure, its end cap main body when connecting is directly to contact with cutting ferrule, the fragility during end cap high temperature in addition makes too tight that end cap can not twist, thereby causes the joint phenomenon of leakage easily.

The utility model content

Goal of the invention of the present utility model is: at the problem of above-mentioned existence; provide a kind of ITO etching machine simple in structure, easy to maintenance to wave and spray the comb end cover structure; this structure has significantly reduced the cost of changing parts, has avoided simultaneously revealing the shutdown that soup causes because of comb.

The technical solution of the utility model is achieved in that a kind of ITO etching machine waves injection comb end cover structure, comprise the end cap main body, the cross section of described end cap main body is concave shape, described end cap bottom part body is provided with through hole, be provided with screw thread in described end cap main body inboard, it is characterized in that: the aperture of described through hole is greater than the diameter that is arranged on cutting ferrule on the comb, in described end cap main body, be provided with two half-round clamping rings, the annulus external diameter that described two half-round clamping rings form is greater than the aperture of through hole, and its internal diameter is less than the diameter of cutting ferrule on the described comb.

ITO etching machine described in the utility model waves and sprays the comb end cover structure, and its described end cap main body and half-round clamping ring are made by the voltalef material.

The utility model will have end cover structure now and become split-type structural, the through hole of end cap main body is enlarged, make it can pass the cutting ferrule that the comb end is provided with, and then cooperate the snap ring of two semicircles, utilize snap ring that the end cap main body is stuck in the cutting ferrule place, again the end cap main body is screwed on total gas thread, thereby comb is fixed on the soup house steward, and the end cap material is replaced by voltalef.When going wrong, can change end cap at any time like this, and comb assembly and total gas thread is fixing also better, sprays soup from the joint and come out waving Shi Buhui.

Adopt the beneficial effect of above-mentioned end cover structure to be: 1, having avoided revealing the glass surface localized ejection pressure that causes because of tube stub place soup increases, thereby causes the situation of product rejection; 2, reduce the replacement charge of spare part, under the situation of this structure design, do not needed to prepare whole comb assembly, only need make the spare part of a part of end cap, can satisfy production requirement, greatly reduced the maintenance cost of equipment; 3, after the design that restructures, time and number of times that this equipment is shut down because of the end cap problem obviously reduce.

Embodiment

Below in conjunction with accompanying drawing, the utility model is done detailed explanation.

In order to make the purpose of this utility model, technical scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

As Fig. 3, shown in 4 and 5, a kind of ITO etching machine waves and sprays the comb end cover structure, comprise end cap main body 1, the cross section of described end cap main body 1 is concave shape, described end cap main body 1 bottom is provided with through hole 2, be provided with screw thread in described end cap main body 1 inboard, the aperture of described through hole 2 is greater than the diameter that is arranged on cutting ferrule 4 on the comb 3, in described end cap main body 1, be provided with two half-round clamping rings 5, the annulus external diameter that described two half-round clamping rings 5 form is greater than the aperture of through hole 2, its internal diameter is less than the diameter of cutting ferrule 4 on the described comb 3, and described end cap main body 1 and half-round clamping ring 5 are made by the voltalef material.

The utility model will have end cover structure now and become split-type structural, the through hole of end cap main body is enlarged, make it can pass the cutting ferrule that the comb end is provided with, and then cooperate the snap ring of two semicircles, utilize snap ring that the end cap main body is stuck in the cutting ferrule place, again the end cap main body is screwed on total gas thread, thereby comb is fixed on the soup house steward.This structure can make maintenance convenient, saves a large amount of maintenance times, can also reduce the cost of changing parts, avoids revealing the shutdown that soup causes because of comb.

The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
