Description
Technical field
The present invention relates to a kind of fast-assembling flange, belong to mechanical manufacturing field.
Background technology
Electric wire is because be easily subject to the destruction of external force; in use; will there be the protection of hard spool outside; in electric wire end; hard spool and dividing plate connecting portion; adopt flange arrangement to connect hard spool and dividing plate, prevent vibration abrasion fixing seal hard spool simultaneously, the electric wire that realization vibration, dust, water spatter under three kinds of environmental conditions protects.
As shown in Figure 1, for the schematic diagram of two halves formula flange arrangement in prior art, hard spool 6 blocks by two halves flange 7, butted part securing member 4 is locked, by securing member 4, two halves flange 7 is fixedly connected with dividing plate 5 again, thus hard spool and dividing plate are fixed, but need bilateral to operate when two halves formula flange arrangement and hard spool are locked, the operating space of the instrument such as spanner used when leaving clinch fastener, required operating space is larger.
As shown in Figure 2, for the schematic diagram of prior art medial end portions welded flange structure, the mode and the welded flange 8 that hard spool 6 are passed through welding weld together, then by securing member, flange and dividing plate are fixed, but, welding easily produces distortion, and is difficult to other material spools such as applicable thin-wall aluminium pipe, stainless steel tube.
Also has a kind of flange arrangement, when fixing the hard spool of circular cross-section, the end of hard spool is provided with screw thread, flange inner wall is arranged the screw thread matched, hard spool is connected with flange by screw thread, is being fixed on dividing plate by securing member, but machining screw, add the operation of processing, be not suitable for the spool of thin-walled, and be not suitable for the fixing of the hard spool of noncircular cross section.
Current structure shortcoming electric wire fixed function, just the hard spool outside electric wire is fixed, the electric wire of unfixing the inside, so when there is vibration outside, also the connection of electric wire can be affected, and sealing effectiveness is bad, the restriction needing bilateral operation to be subject to small space had during current Standard causes installing difficulty and poor sealing, if by spool and flange welding, easily produce distortion and be difficult to applicable thin-wall aluminium pipe, other material spools such as stainless steel tube, if when spool and flange are threaded connection, be not suitable for the spool of thin-walled spool and on-circular cross-section.
For solving the problem, the invention provides a kind of fast-assembling flange, simplifying processing and assembling and being suitable for the installing/dismounting operation of small space, simple to operate, improve sealing, and the electric wire of hard spool inside to be fixed.
