The outer wall of gold pad piece is connected, and acts perpendicularly to alloy pad and promotes bow line inner core in alloy pad clamping body, in body
Wall and alloy gasket surface are equipped with anti-slop serrations, increase contact surface frictional force, are further ensured that the company of bow line inner core and body
Fastening is connect, tube wall is provided with the water-proof self-adhesion band and shrinkage tube boot that length with matching is longer than tube length, makes pipe
Body sealing effectiveness is more preferable, waterproof, corrosion-resistant, the external force infringement effectively in reduction body suffered by bow line inner core, shrinkage tube boot
Outer surface scribbles the ink of one layer of heat discoloration, and ink layer color changes according to temperature range and changed automatically, can be with eye-catching
It was found that the temperature anomaly of bow line inner core junction, conveniently investigates and removes a hidden danger.
Brief description of the drawings
Fig. 1 is that the utility model uses connection structure diagram；
Fig. 2 is Fig. 1 A-A views；
Sequence number in figure：1 body；2 trip bolts；3 screwed holes；4 alloy pads；5 bow lines；6 bow line inner cores；7 waterproofs

Embodiment
As Figure 1-Figure 2, the bow wire-connecting device of a kind of heat discoloration, comprising by high-strength, antioxidant aluminium alloy material
Body 1 made of material, 1 long 160mm of body, the internal diameter 25mm of body 1, the external diameter 30mm of body 1, the conductive paste that the inwall of body 1 scribbles
Layer 11 can strengthen the electric conductivity of body 1, anti-oxidant, corrosion resistance, be provided with axially spacedly on the both ends tube wall of body 1 many
In three screwed holes 3, screwed hole 3 can be evenly spaced apart to be distributed in the both ends tube wall homonymy of body 1, can also be evenly spaced apart to be distributed
In the both ends tube wall opposite side of body 1, it is rectangular that the inwall of body 1 corresponding to screwed hole 3 is provided with the arc being engaged with the inwall of body 1
Strip alloy pad 4, in use, both ends bow line 5 inserts the part of body 1, first to divest bow line 5 exhausted for the utility model connection
Edge layer, remaining bow line inner core 6 insert body 1 respectively from the both ends of body 1, reach the center of body 1 and realize both ends bow line
Inner core 6 docks, and trip bolt 2 is connected with screwed hole 3 with merging with the outer wall of alloy pad 4, and trip bolt 2 acts perpendicularly to
Alloy pad 4, trip bolt 2 is turned to the axis center of body 1 respectively, the clamping bow line inner core 6 of alloy pad 4 can be promoted, its
