Description
Technical field
The present invention relates to wind tunnel test field, in particular in test model installation and the combination used in unloading process
Formula putty scraper.
Background technology
In wind tunnel test, a support part will support different models, and model can face during installation is tested
Change different parts.On model in wind tunnel, in order to ensure the smooth development of experiment in order to obtain experiment number well
According to, therefore the surface of model needs to keep smooth so that in atmospheric flow field, it is unaffected that air-flow blows over model surface.In order to
This purpose is realized, the connector that model all parts use typically all uses mode connects for screw, and the connection of screw typically will
Sink to inside model surface so that there is a gap in attachment screw rear nut and model surface, in order to make up this gap,
It is conventional all to be filled using putty, then retell the smooth of the floating holding model surface of putty.
During whole experiment, corresponding component needs often to change, and the exemplary operation order changed is：Take out
Putty, removable screw, replacing model assembly, mounting screw, screw hole filling putty and equating in screw hole.Existing way
When, the putty in hole is taken out using single thin bar, finally reuses single scraper equating.In this process, because spiral shell
The reason for pit, make it that thin bar is very thin, is easy to hurt sb.'s feelings in use, and conventional thin bar can not clean out well
Putty；Thin bar separates with scraper to be used so that being easy to cause putty knife or thin bar to be fallen because of inconvenient to carry in carrying process
Fall, and the height of general operation is very high, after part drops, the putty knife edge of a knife is easy to damage, and influences to use.
The content of the invention
The purpose of the present invention is to propose to improve on the basis of existing, there is provided a kind of combined type putty scraper, by thin bar with scraping
Knife is combined into one, and modification is made to blade construction so that more convenient to use and carrying.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of wind tunnel test combined type putty scraper, including scraper and handle, the scraper include bottom surface and top surface, institute
State top surface area and be less than base area, the bottom surface each while to corresponding top surface each while form a knife
Face, the knife face are trapezoidal；Be provided with connecting hole on one of knife face, in one end insertion connecting hole of the handle with
Scraper connects, and the end in the handle insertion scraper is to root out portion；Magnet is provided with the scraper.
In the above-mentioned technical solutions, three knife faces are provided with the scraper, the 4th knife face is joint face, the connection
The top in face in overlook direction with overlapping below.
In the above-mentioned technical solutions, three described knife faces are inclined plane, and joint face is vertical plane.
In the above-mentioned technical solutions, the portion of rooting out of the handle is one with reeded thin bar.
In the above-mentioned technical solutions, axis direction of the groove along thin bar is set, and the end of thin bar is towards handle side
To causing the side of groove into curve transition.
In the above-mentioned technical solutions, the angle that two sides of the groove are formed is obtuse angle.
In the above-mentioned technical solutions, a thin bar is connected with the other end on the handle.
In the above-mentioned technical solutions, the thin bar of the other end is same root thin bar in the thin bar and handle for rooting out portion, institute
State thin bar and pass through handle.
In the above-mentioned technical solutions, the magnet is arranged on the bottom surface or top surface of scraper, and is fixed with bottom surface or top surface
Connection.
In the above-mentioned technical solutions, the magnet or fixation are encapsulated in the scraper between bottom surface and top surface.
Compared with prior art, the beneficial effects of the invention are as follows：
In the present invention, scraper integrates with handle so that band kit is only needed in carrying, and in scraper
In be provided with magnet, then in use, when need not in use, can by magnet adsorption on model, without
It is placed using single device, carrying convenience；
For the setting of thin bar in the present invention, groove shapes are designed to using in the portion of rooting out so that rooting out the mistake of putty
Putty can easily be promoted in groove, conveniently rooted out by Cheng Zhong, the portion of rooting out,
The implementation of the present invention solves the problem of instrument carrying, and the improvement of device causes operating efficiency to be obviously improved.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of handle in the present invention；
Wherein：1 is magnet, and 2 be scraper, and 3 be thin bar, and 4 be handle, and 5 be to root out portion.
Embodiment
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As shown in figure 1, the structure of the present invention is mainly formed with two parts, one be scraper, and another is handle, handle and
Scraper links together.Scraper in the present invention includes a bottom surface and a top surface, and the area of top surface is less than bottom surface, therefore makes
From bottom surface each while on corresponding top surface while when formed an inclined inclined-plane, the inclined-plane be scraper knife face,
Knife face is one trapezoidal.One of knife face is arranged to joint face, handle is connected on joint face, in order to ensure connection can
Lean on, joint face is mutually perpendicular to bottom surface and top surface.So, in use, three knife face each knife faces can be carried out
Work, timely one knife face of any of which damage, and other knife faces can continue to use, it is ensured that service efficiency and life-span.
As shown in Fig. 2 being provided with a cavity along scraper body on joint face, handle is inserted in cavity, hand
It can use and be threadedly coupled between handle and cutter hub, the structure that can also just withhold is attached, and the part of cavity is inserted on handle
To root out portion, the portion of rooting out is used to carry out shoveling function to putty.It is a thin bar to root out portion, is set in thin bar along axis direction
Fluted, the angle that two sides of groove are formed is obtuse angle, and so setting is advantageous in that putty when forcibly driving thin bar, greasy
Son can carry out groove, so as to take putty out of by rooting out portion.And in the other end of handle, thin bar through handle it is exposed
Outside handle so that the aperture of corresponding major diameter directly can carry out rooting out for putty with this one end of thin bar, and root out the end in portion
Portion is pointed structures, and thinner, is rooted out for carrying out putty to the aperture of minor diameter.
Magnet is additionally provided with scraper in the present invention, magnet can be arranged on top surface, can also be arranged on bottom surface,
It can certainly be encapsulated in inside the cutter hub of scraper, it is exactly to say that scraper is adsorbed on model by the attraction of magnet that it, which is acted on,
Like this when inapplicable scraper, it can directly remove handle and enter scraper absorption separately from thin bar on model aircraft
Row putty is rooted out.Or whole scraper can also adsorb other operations are carried out on model when not in use.
The structure of the present invention is simple, is highly convenient for carrying.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
