Abstract
The utility model is related to a kind of screw connection structures, including screw hole, screw rod and spiral metal set；The internal thread of the screw hole and the external screw thread of screw rod form gap；The spiral metal set internal face forms internal thread, and the spiral metal set outside wall surface forms external screw thread；The internal thread of the spiral metal set matches threaded connection with external thread of screw, and the external screw thread of the spiral metal set matches threaded connection with the internal thread of screw hole.
Description
Technical field
The utility model belongs to workpiece with threaded hole in mold and uses technology for a long time, is related to a kind of threadeds connection and ties
Structure.
Background technology
For workpiece with threaded hole in many molds, the dropout of screw portion screw thread can be replaced, but the pedestal of loading screw
Or bottom plate, especially to thread off similar to the base thread hole of vacuum cup, replacement is equivalent to recasting one set of die, from cost,
It is not cost-effective.So being directed to problems, just there is the design that threaded hole fitted lining covers when mold is processed, but conventional bushings exist more
The problem of changing inconvenience, and can not being taken out after damaging.
Invention content
The purpose of the present invention is：A kind of screw connection structure is provided, realizes that bushing is easy for installation, and be easy to take after damaging
Go out.
The technical scheme is that：A kind of screw connection structure, including screw hole, screw rod and spiral metal set are provided；Institute
The external screw thread of the internal thread and screw rod of stating screw hole forms gap；The spiral metal set internal face forms internal thread, the spiral
Metallic sheath outside wall surface forms external screw thread；The internal thread of the spiral metal set matches threaded connection with external thread of screw, described
The external screw thread of spiral metal set matches threaded connection with the internal thread of screw hole.
Another screw connection structure, including screw hole, screw rod and spiral metal wire are provided；The internal thread and spiral shell of the screw hole
The external screw thread of bar forms spiral gap；The spiral metal wire is clipped in spiral gap, realizes screw rod and spiral metal wire
The matched threaded connection of screw thread, and realize screw hole and the matched threaded connection of spiral metal wire screw thread simultaneously.
The present invention includes the following steps：
(1) it is drilled on bottom plate using the corresponding drill bit of standard.
(2) with specific steel wire bushing special screw tap tapping, notice that tapping depth must be over liner sleeve length.
(3) steel wire lining set is packed into specific installation tool, adjusts position of the bushing in installation tool.
(4) installation tool is directed at manufactured bush hole on bottom plate, gently pushes and be transferred to bushing, cannot uses too big
Strength prevents random button, dropout.
(5) it removes installation tool, block and take out the installing handle of screw-thread bush, i.e. completion installation with the special device that thrusts.
It is an advantage of the invention that：
The present invention realizes that bushing is easy for installation, and is easy to take out after damaging.
Description of the drawings
Fig. 1 is 3D schematic diagrames, wherein 1- spiral metals set.
Fig. 2,3 be the present invention use schematic diagram；
Wherein, 1- spiral metals set, 2- spiral metal wires, 3- screw rods, 4- screw holes, 5- installation tools.
Specific implementation mode
The present invention is described in further details below.
A kind of screw connection structure, including screw hole 1, screw rod 2 and spiral metal set 3 are provided；The internal thread of the screw hole with
The external screw thread of screw rod forms gap；The spiral metal set internal face forms internal thread, and the spiral metal set outside wall surface is formed
External screw thread；The internal thread of the spiral metal set matches threaded connection, the outer spiral shell of the spiral metal set with external thread of screw
Line matches threaded connection with the internal thread of screw hole.
Another screw connection structure, including screw hole 1, screw rod 2 and spiral metal wire 4 are provided；The internal thread of the screw hole
Spiral gap is formed with the external screw thread of screw rod；The spiral metal wire is clipped in spiral gap, realizes screw rod and spiral gold
Belong to the matched threaded connection of screw thread of silk, and realizes screw hole and the matched threaded connection of spiral metal wire screw thread simultaneously.
