Abstract
A lifting glass window special vertical frame for a laboratory fume cupboard is formed by a main body, a mounting plate and a glass mounting groove. The main body, the mounting plate and the glass mounting groove are a whole combined together, are made into a sectional material made of an aluminum alloy material and can be randomly cut and used in the length direction as required. A transverse section graph of the lifting glass window special vertical frame for the laboratory fume cupboard is an irregular polygon formed by an approximately main body graph shaped like a Chinese character ri and formed by edges with a certain line width and a rectangular mounting plate graph connected to the main body graph. The edge of the top of the main body graph shaped like the Chinese character ri is provided with the glass mounting groove, and one side edge opposite to the glass mounting groove is connected with the mounting plate. The lifting glass window special vertical frame used for the laboratory fume cupboard and provided with the mounting plate greatly facilitates product assembly, and product reliability is also improved.
Description
Technical field
The utility model relates to a kind of laboratory hood parts, says more definitely and relates to the special-purpose vertical frame of a kind of laboratory hood elevating glass form.
Background technology
Laboratory hood elevating glass form is to be connected with hoistway with the vertical frame of forms, and therefore, in whole system, the performance of vertical frame seems very important.At present.What the vertical frame that laboratory hood elevating glass form is used generally adopted is the section bar that normal domestic glass window shape of peripheral frame is made by aluminium alloys or polyvinyl chloride thermoplas tic resin composite, because normal domestic glass window is very low to the requirement of unlatching and closing function, do not consider precision and stability when glass window switch moves, therefore independently slideway is not installed, so, normal domestic glass window shape of peripheral frame is not just designed for the installing component being connected with slideway yet, while making laboratory hood elevating glass form with such section bar, must first on the vertical frame in the left and right sides of forms, fix respectively installing component is installing plate, just can make forms be connected with slideway.In actual production process, mounting plate is comparison elaboration, expend a lot of time, even like this, because material and the assembling mode of the vertical frame of laboratory hood elevating glass form are limit, this procedure is difficult to guarantee assembly precision, this will cause laboratory hood elevating glass form operation to have some setbacks and even in the stuck phenomenon in a certain position, then produce noise, also accelerated wear test, reduced the application life of whole system, the more important thing is and can cause forms when moving and parking, likely to occur tilt phenomenon.For the laboratory hood of employing exhaust air rate and forms open amount automatic tracking system, the height that the forms that system can detect according to window position sensor promote, the corresponding exhaust blower rotating speed of Lookup protocol, guarantees in the course of work to be negative pressure in vent cabinet, position due to a window position sensor vertical frame of testing laboratory's vent cabinet elevating glass form one side, whether None-identified forms have tilt phenomenon, and system is the air inlet duct area that lower frame is opened below level is calculated forms while parking according to forms, calculate according to this exhaust blower rotating speed, if there is tilt phenomenon in forms when parking, the air inlet duct area that system is calculated automatically so will be inaccurate, the rotating speed of exhaust blower just can exact matching yet, in this case, if exhaust blower rotating speed is less than the rotating speed that actual air-admitting surface should be mated, likely cause pernicious gas to reveal to laboratory through air inlet duct, threaten the safety of experiment.
Utility model content
In view of the shortcomings of the above-mentioned laboratory hood elevating glass form generally using at present with vertical frame, the purpose of this utility model is to provide a kind ofly makes that glass vision panel elevating safety is reliable, noise is low, long service life, production are assembled the special-purpose vertically frame of simple laboratory hood elevating glass form.For achieving the above object, the utility model has adopted following technical scheme: the special-purpose vertical frame of a kind of laboratory hood elevating glass form, by main body, installing plate and glass installation groove, formed, it is characterized in that: main body, installing plate and glass installation groove are an integral body of combining, by aluminum alloy materials, make section bar, on length direction, can intercept arbitrarily according to demand use; The cross section figure of the special-purpose vertical frame of laboratory hood elevating glass form is the main graph that is similar to " day " font of a formation of the limit with certain live width and is connected to the synthetic irregular polygon of rectangular installing plate graphical set on main graph, wherein the limit at " day " font top is provided with glass installation groove, on a side relative with glass installation groove, is connected with installing plate; The special-purpose vertical frame of laboratory hood elevating glass form is an irregular multiaspect solid, and wherein the angle between each adjacent surface is right angle, and on the center line of the face width that is not attached thereto in main body of installing plate.
The beneficial effects of the utility model are: laboratory hood elevating glass form adopts after the technical solution of the utility model, during assembling, removed the trouble that fixedly mounts respectively parts installing plate on the frame of the left and right sides of forms from, simple in structure, make manufacturing process energy-conservation, efficient.Can make that the operation of laboratory hood elevating glass form is more solid and reliable, structure is simpler, noise is lower simultaneously.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model characteristic, for making the professional and technical personnel can clearer technological means of the present utility model, and can be implemented according to the content of manual, with preferred embodiment of the present utility model, coordinate accompanying drawing to elaborate below.
