Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
One kind is flexible, rotates, self-locking electric insulation bar, including the interior body of rod 2 and the outer body of rod 1, the outer body of rod 1 are set using hollow
Meter, and the interior body of rod 2 and the outer body of rod 1 are the insulation body of rod, the interior body of rod 2 is slidably connected in the outer body of rod 1, one end one of the interior body of rod 2
Body formed to have anti-drop block, the interior body of rod 2 is connected to lantern ring 3 close to the position sliding sleeve of the outer body of rod 1, on lantern ring 3 there are two integrated moldings
Screw thread piece 4 is integrally formed flexible 6 on each screw thread piece 4, is threaded with retaining ring 5 jointly on two screw thread pieces 4,
Integrally formed with screwed ring 7 in retaining ring 5, integrally formed with tabletting 8 in screwed ring 7, one end inner wall of the outer body of rod 1 is close to lock
Integrally formed with gradual change ring 10, the interior body of rod 2 can occur flexible in the outer body of rod 1 and rotate, the diameter of lantern ring 3 for the position of tight ring 5
Diameter between greater than two screw thread pieces 4, the diameter of retaining ring 5 are greater than the diameter of screwed ring 7.
Screw thread piece 4 of the present invention, elastic piece 6, tabletting 8 are all made of circular-arc-shaped design, guarantee good stickiness.Tabletting
8 use gradual design, tabletting 8 close to the outer body of rod 1 one end thickness from high to low, the thickness of gradual change ring 10 is close to retaining ring 5
One end thickness from low to high, when tabletting 8 is supported to gradual change ring 10, can make tabletting 8 squeeze elasticity under the compressing of gradual change ring 10
Piece 6.
Elastic piece 6 of the present invention is coated with anti-slip layer 9 close to one end of the interior body of rod 2, and antislip paint or anti-can be used in anti-slip layer 9
Sliding coating is made, and can increase the frictional force of elastic piece 6 Yu the interior body of rod 2, improves locking stability.Screwed ring 7 in retaining ring 5
It is threadedly coupled with the outer body of rod 1, when so that retaining ring 5 rotating, retaining ring 5 can move on the outer body of rod 1, and make retaining ring 5 and outer
The body of rod 1 carries out stable relation.The interior diameter of retaining ring 5 is less than the overall diameter of lantern ring 3, and lantern ring 3 is prevented to be screwed into retaining ring 5.
The material of the interior body of rod 2 and the outer body of rod 1 is electro-insulating rubber.
The present invention rotates lantern ring 3, so that 3 band of lantern ring in use, when sliding position is certain in the outer body of rod 1 for the interior body of rod 2
Dynamic screw thread piece 4 rotate and move in retaining ring 5, so that lantern ring 3, screw thread piece 4 and elastic piece 6 are mobile and enter outer bar
In body 1, retaining ring 5 is rotated at this time, so that retaining ring 5 drives screwed ring 7 and tabletting 8 mobile, screwed ring 7 is threaded in outer bar
On body 1, when the outer wall of tabletting 8 arrives on the inner wall of gradual change ring 10, with the movement of retaining ring 5,8 stress of tabletting is gradually tapered up,
Tabletting 8 gradually squeezes elastic piece 6, so that elastic piece 6 is gradually bonded locking with the interior body of rod 2, when carrying out elastic, catches set on the other hand
Ring 3 is motionless, turns retaining ring 5 on the other hand, back-outs retaining ring 5, prevents that lantern ring 3 is driven to rotate.
