Description

TECHNICAL FIELD

[0001] The utility model relates to a dust blowing gun, more specifically, it relates to a protective integrated dust blowing gun. BACKGROUND

[0002] As an industrial cleaning tool, the dust blowing gun is widely used in factories, equipment installation and maintenance processes, especially in narrow spaces, high places or pipeline interiors that are difficult to directly contact with hands for dust removal operations. The working principle of the pneumatic dust blowing gun is based on air amplification effect, which produces powerful and precise airflow by reducing the consumption of compressed air, and drives the surrounding air to work together to achieve high-efficiency cleaning effect. However, the existing dust blowing gun has some limitations in use. When using the dust blowing gun for cleaning operation, especially when blowing dust on deep hole parts, gas backflow may cause flying of impurities such as chips and cutting fluid, which may cause potential serious injury risk to the operator, especially the eyes. In order to protect the operator, some dust blowing guns are equipped with protective covers at the air pipe. Although the protective cover can protect the user to a certain extent, due to the splashing of chips and cutting fluid, the surface of the protective cover is easy to attach these substances, which seriously affects the visual clarity, making it difficult for the operator to accurately position the deep hole position, and also reduces the work efficiency and affects the cleaning effect. SUMMARY

[0003] In view of the deficiencies in the prior art, the utility model aims to provide a protective integrated dust blowing gun with double-layer gas protective cover device.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a protective integrated dust blowing gun, comprising a dust blowing gun body and a gas screen assembly, the gas screen assembly comprises a gas screen opening and closing part and a limiting locking part, the gas screen opening and closing part comprises an inner ring and a sleeve ring, both the inner ring and the sleeve ring are equipped with double-layer fan-shaped groove structure and have the function of relative rotation. The double-layer gas protective cover formed by the fan-shaped groove structure can effectively resist the flying of impurities such as chips and cutting fluid and realize complementary enhancement in the blind area of the respective coverage range. The limiting locking part is provided with a flat key, which is accurately positioned in the inner ring key groove. At the same time, the flat key slides in the circular arc sliding groove of the sleeve ring to realize the relative rotation of the sleeve ring in the predetermined range. The circular arc sliding groove two terminals accurately limit the flat key, and the principle of extrusion friction is used to realize the stable locking of the gas screen assembly.

[0005] By adopting the above technical scheme, when the dust blowing gun is used for operation on deep hole type parts, the outer sleeve ring is rotated to a predetermined position, and the gas screen assembly is locked through the extrusion friction force of the flat key and the outer sleeve ring, at this time the dust blowing gun is put into use, the double-layer gas protection cover formed by the double-layer fan-shaped groove structure of the inner ring and the outer sleeve ring can effectively resist impurities such as chips and cutting fluid, and the visual clarity can be significantly enhanced. The gas screen assembly is simple to operate and easy to manufacture, and can effectively protect the operator and eliminate potential safety hazards.

[0006] The utility model further sets up: gas screen opening and closing spare, inner ring and outer sleeve ring all are equipped with double-layer fan groove structure, and fan-shaped groove shape is similar, and have the function of relative rotation.

[0007] By adopting the above technical scheme, when the dust blowing gun is used for operation on deep hole type parts, the outer sleeve ring is rotated to a predetermined position, and the gas screen assembly is locked through the extrusion friction force of the flat key and the outer sleeve ring, at this time the dust blowing gun is put into use, the double-layer gas protection cover formed by the double-layer fan-shaped groove structure of the inner ring and the outer sleeve ring can effectively resist impurities such as chips and cutting fluid, and the visual clarity can be significantly enhanced. The gas screen assembly is simple to operate and easy to manufacture, and can effectively protect the operator and eliminate potential safety hazards.

[0008] The utility model further sets up: gas screen assembly, a precise circular arc sliding groove is designed in the inner ring of the outer sleeve ring, the geometric shape of the sliding groove is that the width in the middle is relatively large, and gradually reduces towards both ends.

[0009] By adopting the above technical scheme, when the dust blowing gun is used for operation on deep hole type parts, the design helps to reduce friction in the rotation of the outer sleeve and provides stable guiding effect. The two terminals of the arc represent the opening and closing positions of the gas screen and are accurately limited, which can prevent the opening or closing of the gas screen from failing, and facilitate the opening and closing operation of the operator.

[0010] The utility model further sets up: gas screen assembly, a key groove is designed in the inner ring. The flat key is accurately positioned in the key groove, the vertical size of the flat key is slightly larger than the depth of the key groove, and the flat key is guided to slide in the arc guide groove of the outer sleeve ring.

[0011] By adopting the above technical scheme, the two terminals of the arc sliding groove accurately limit the flat key and lock the gas screen assembly by extrusion friction force to ensure the fastening of the gas screen assembly under the action of gas flow, so that unstable phenomena of gas screen opening and closing and limiting are avoided.

[0012] Compared with the prior art, the utility model has the advantages that: the double-layer gas protection cover formed by the protective integrated dust blowing gun for the deep hole type part cleaning can effectively resist the splashing cutting chips, cutting fluid and other impurities, so as to achieve the purpose of protecting the operator, eliminates the safety hidden trouble existing in the use process of the dust blowing gun, and can guarantee good visual clarity.
