Based on the technical defect, the utility model aims to provide a connection mine dryer that is used for the mine dryer connection structure in colliery, can be quicker, safer. The utility model aims at realizing through the following technical scheme:
a mine air duct connecting structure comprises two air ducts which are mutually connected and a strapping tape which is fixed at the joint of the air ducts; the connecting end of each air duct is provided with an air duct ring, a magnet is wrapped in the air duct ring, and a plurality of flexible clamping jaws are uniformly distributed on the outer circumference of the air duct ring; a groove along the length direction of the strapping tape is arranged in the middle of the inner surface of the strapping tape, and two ends of the strapping tape are provided with corresponding buckles; the two air ducts are connected in an adsorption mode through respective air duct rings to be connected for the first time, the strapping tape is fastened outside the two air duct rings through buckles, and the flexible clamping jaws are wrapped in the grooves to be connected for the second time. The connection of the two times ensures the rapidity and the sealing performance of the connection of the air duct. The cooperation of flexible jack catch and recess has increased and has tied up the steadiness.
Further optimization, the flexible clamping jaws are made of nylon materials and are arc-shaped or inverted-L-shaped, and the shape of the flexible clamping jaws is that the air duct rings are bent outwards.
Furthermore, the number of the flexible clamping jaws arranged on each air cylinder ring is not less than 10.
Furthermore, the strapping tape is made of nylon.
Furthermore, the air duct ring is made of plastic materials or rubber materials.
Furthermore, the magnet is annular, the inner diameter of the magnet is the same as that of the air cylinder ring, and the outer diameter of the magnet is smaller than that of the air cylinder ring.
Furthermore, the magnets are a plurality of magnetic sheets which are uniformly distributed inside the air duct ring.
The utility model has the advantages that:
1) The utility model discloses the practicality is strong, and simple operation, safety can be connected the dryer fast, have improved work efficiency, practice thrift operating time.
2) The utility model discloses the investment is little, convenient to use, and the strong magnet in the usable dryer circle carries out preliminary fixed, has practiced thrift manpower and materials, agrees with through the recess of strapping and the jack catch of dryer at last, and the buckle locks, and safe and reliable is sealed tight, reduces the air leakage.
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
