Description
Technical field
The utility model relates to a kind of dust catcher accessory, is specifically related to a kind of sweep-up pipe of dust catcher.
Background technology
Carbon fiber is fibrous carbon materials, and phosphorus content is more than 90%.It is to utilize the carbonization and making under inert gas medium and high temperature state of various organic fibers.A kind of as high-performance fiber, the inherent characteristic of the existing material with carbon element of carbon fiber, the soft machinability that has both again textile fabric, it is the most important reinforcing material of advanced composite material, every field in military affairs and civilian industry obtains extensive use, from civilian industries such as space flight, aviation, automobile, electronics, machinery, chemical industry, light textiles to sports equipment with leisure goods etc.Carbon fiber is also used widely in dust catcher accessory now.
But the sweep-up pipe of existing dust catcher mostly is plastic material, and length fixes, like this sweep-up pipe life-span shorter, the scope of application is single.
Utility model content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of sweep-up pipe that can regulate the dust catcher of length.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A sweep-up pipe, comprises pipe shaft, suction port, it is characterized in that, pipe shaft comprises telescopic flexible tube section and straight hard tube section, and above-mentioned suction port is connected with flexible tube section, and above-mentioned hard tube section is provided with external screw thread near the periphery at the position of flexible tube section; Above-mentioned suction port is provided with concave station near the inside of one end of flexible tube section, and the bottom surface of above-mentioned concave station is connected with flexible tube section, and the sidewall of above-mentioned concave station is provided with the internal thread coordinating with external screw thread.Above-mentioned suction port is carbon fiber dust suction mouth, and above-mentioned pipe shaft is carbon fiber pipe shaft.
Further, the external diameter of above-mentioned flexible tube section equals the internal diameter of hard tube section.
Further, the external diameter of above-mentioned hard tube section equals the internal diameter of concave station sidewall.
Further, above-mentioned suction port is the suction port that internal diameter expands gradually.
Further, above-mentioned flexible tube section is the flexible pipe that carbon cloth surrounds, and above-mentioned hard tube section is carbon fibre reinforced pipe.
Usefulness of the present utility model is: carbon fibre material has the advantages such as intensity is high, corrosion-resistant, long service life.Flexible tube section can stretch again, can regulate as required the length of the sweep-up pipe of dust catcher, and hard tube section can guarantee the beeline of dust suction, promotes pick-up performance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The implication of Reference numeral in figure:
10-pipe shaft,
11-flexible tube section, 110-concave station, the bottom surface of 110a-concave station, the sidewall of 110b-concave station, 111-internal thread,
12-hard tube section, 121-external screw thread,
20-suction port.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
A kind of sweep-up pipe as shown in Figure 1, comprises pipe shaft 10, suction port 20, and pipe shaft 10 comprises telescopic flexible tube section 11 and straight hard tube section 12, and flexible tube section 11 is between suction port 20 and hard tube section 12.Hard tube section 12 is provided with external screw thread 121 near the periphery at the position of flexible tube section 11, suction port 20 is provided with concave station 110 near the inside of one end of flexible tube section 11, the bottom surface 110a of concave station 110 is connected with flexible tube section 11, and the sidewall 110b of concave station 110 is provided with the internal thread 111 coordinating with external screw thread 121.
The external diameter of flexible tube section 11 equals the internal diameter of hard tube section 12.Flexible tube section 11 can be fixedly connected with the inwall of hard tube section 12 like this.The external diameter of hard tube section 12 equals the internal diameter of concave station 110 sidewalls, and hard tube section 12 can stretch in boss 110 and be connected with internal thread 111 by the external screw thread 121 cooperatively interacting with concave station 110 like this.
As a kind of preferred version, the suction port that suction port 20 expands gradually for internal diameter, the internal diameter of suction port 20 is larger the closer to pipe shaft 10 its internal diameters, and less dust suction entrance can increase the local suction of dust catcher.In order to increase the intensity of suction port 20 and pipe shaft 10, suction port 20 is carbon fiber dust suction mouth, and pipe shaft 10 is carbon fiber pipe shaft.As a kind of preferred version, the pipe shaft that flexible tube section 11 surrounds for carbon cloth, hard tube section 12 is carbon fibre reinforced pipe, hard tube section 12 is composited by pitch tube and the carbon cloth that is positioned at pitch tube outside.
More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection domain of the present utility model.
