Problems solved by technology

In this process, because of the threaded hole, the thin rod is very thin, which is easy to hurt people during use, and the conventional thin rod cannot clean the putty well; the thin rod and the scraper are used separately so that the It is easy to cause the putty knife or the thin rod to fall due to the inconvenience of carrying, and the height of the general operation is very high. When the part is dropped, the edge of the putty knife is easily damaged and affects the use

Embodiment Construction

[0023] Below in conjunction with accompanying drawing, the present invention is described in detail.

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0025] like figure 1 As shown, the structure of the present invention mainly consists of two parts, one is a scraper, and the other is a handle, and the handle is connected with the scraper. Scraper among the present invention comprises a bottom surface and a top surface, and the area of ​​top surface is less than bottom surface, therefore makes when forming an inclined slope from each limit of bottom surface to the limit on corresponding top surface, and this slope is the blade face of scraper ...

Abstract

The invention discloses a combined putty scraper for a wind tunnel test. The combined putty scraper comprises a scraper body and a handle. The scraper includes a bottom surface and a top surface, wherein the area of the top surface is smaller than that of the bottom surface. Each side of the bottom surface is connected to each side of the corresponding top surface to form a cutting surface in a trapezoidal shape. A connecting hole is formed in one cutting surface. One end of the handle is inserted into the connecting hole and is connected with the scraper body; and the end portion, inserted into the scraper body, of the handle is a wipe-out part. A magnet is arranged at the scraper body. According to the combined putty scraper, because the scraper body and the handle are combined into one, when the scraper is carried, only one set of tools need to be carried. With the magnet arranged at the scraper, when being not in use, the scraper can be attached to the model based on the magnet; and thus no independent unit needs to be placed, so that the scraper can be carried conveniently.

Description

technical field [0001] The invention relates to the field of wind tunnel tests, in particular to a combined putty scraper used in the process of installing and disassembling test models. Background technique [0002] In the wind tunnel test, a supporting part has to support different models, and the model will face replacement of different parts during the installation test. On the wind tunnel test model, in order to ensure the smooth development of the test and obtain good test data, the surface of the model needs to be kept smooth so that in the atmospheric air field, the airflow blowing over the surface of the model will not be affected. In order to achieve this purpose, the connectors used in the various parts of the model are generally connected by screws, and the screw connection is generally sunk into the surface of the model, so that there is a gap between the nut and the surface of the model after the screw is connected. In order to make up for this A gap is usuall...
