Technical field
The utility model relates to a kind of fixing device, particularly a kind of hard tube fixing device.
Background technique
In the daily life people often will be on the sidewall of hard tube retaining element, or securely connect and can separate repeatedly and be connected by link two hard tubes that external diameter is identical, in the prior art, retaining element generally is that the sidewall that earlier that desire is fixing part is attached to hard tube is holed on the sidewall of hard tube, putting on screw or pin again realizes fastening in conjunction with nut, shortcomings such as adopt this implementation to exist manufacturing procedure complicated, assembling speed is slow, and cost height and appearance are not attractive in appearance.Realizing that two hard tubes are fastenedly connected, generally is by disposable connection, as welding or utilizing tackiness agent to connect, still then can't realize when the needs repeated disassembled and assembled; Have plenty of employing will be wherein an end of a pipe connect one section outstanding less than inner tube wall earlier, with this outstanding inwall that inserts another pipe, in two pipe joint borings, put on screw again and realize being fastenedly connected of two pipes in conjunction with nut, though this implementation can be fastenedly connected also can repeated disassembled and assembled, but also have processing and assembly process is complicated, assembling speed slowly, shortcoming such as cost is high and appearance is not attractive in appearance.
The model utility content
The purpose of this utility model is to overcome the shortcoming that exists in the prior art, and a kind of simple in structure, hard tube fixing device that tightness is high is provided.
The utility model is achieved in that a kind of hard tube fixing device, comprise hard tube 1, outer sleeve 3 and interior cover 2, cover 2 is encircled in the intermediate plate of hard tube 1 sidewall by at least two and to be constituted in it is characterized in that, the outer surface of interior cover 2 and the internal surface of outer sleeve 3 are taper, overlap on 2 in outer sleeve 3 is placed in, interior cover 2 and outer sleeve 3 and hard tube 1 drive fit, interior cover 2 internal surfaces are provided with inner surface of inner race flange 4, the sidewall of hard tube 1 has tube wall groove 5, internal surface flange 4 engaging tube wall grooves 5 when interior cover 2 is encircled hard tube.
Described outer sleeve 3 internal surfaces are provided with outer sleeve inner surface recesses 7, and the outer surface of interior cover 2 is provided with lining the outer surface of flange 6 outer sleeves 3 and is placed in 2 o'clock outer sleeve inner surface recesses 7 cooperation lining the outer surface of flanges 6 of interior cover.
Described outer sleeve 3 internal surfaces are provided with outer sleeve internal surface flange 11, and the outer surface of interior cover 2 is provided with lining the outer surface of groove 10, and 2 o'clock outer sleeve internal surface flanges 11 of cover cooperated lining the outer surface of groove 10 in outer sleeve 3 was placed in.
The utlity model has simple and compact for structure, dismantle easy to assembly, with low cost, fastening advantage such as effective.
