Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
As shown in Fig. 1 Fig. 2, the utility model provides a kind of sleeve expansion joint, including outer tube 1, inner tube 2 and reducer pipe
3, outer tube 1 is coaxially set in outside inner tube 2, and 1 right end of outer tube is linked together with reducer pipe 3；Between 2 outer wall of 1 inner wall of outer tube and inner tube
Equipped with internal partition 4,4 outer wall of internal partition is fixedly connected with 1 inner wall of outer tube；4 right end of internal partition is equipped with gag lever post 5, preferred to limit
5 quantity of bar can be 4, and gag lever post 5 includes fixed link 51 and telescopic rod 52 along the circumferential setting of internal partition 4, gag lever post 5, Gu
51 left end of fixed pole is fixedly connected with 4 right end of internal partition, and 51 right end of fixed link is fixedly installed sealing plate 53, and 52 left end of telescopic rod passes through
Sealing plate 53 is inserted into fixed link 51, and telescopic rod 52 is slidably matched with fixed link 51, and limit plate 54 is fixedly installed in 52 left end of telescopic rod,
When limit plate 54 moves right with telescopic rod 52 to sealing plate 53, sealing plate 53 blocks limit plate 54, thus limit telescopic rod 52 after
It is continuous to move right；Baffle 6,6 one end of baffle and the fixed company of 52 right end of telescopic rod are equipped between 2 right end of 52 right end of telescopic rod and inner tube
