Preferably, the righting strip inner wall is arc and is bonded with the outer wall of sleeve body.
Preferably, horizontal in the righting strip to be equipped with the swingle for rotating connection, it is fixed with and helps between swingle
The idler wheel of positive item rotation connection.
Preferably, described sleeve pipe inner body wall is equipped with multiple balls for rotating connection.
Preferably, it is equipped with the sponge strip fixed with righting strip in the idler wheel, the interior of the righting strip is equipped with and sponge strip
The pipeline of connection, righting strip side wall are equipped with the oil nozzle being connected to pipeline.
Preferably, described sleeve pipe ontology is made using 40Cr material.
Compared with prior art, the beneficial effects of the utility model are: the utility model is designed reasonably, production is simple,
The installation easy to disassemble of the righting strip of detachable is replaced, and when serious wear, which only needs to change righting strip, can reduce use cost,
Reducing frictional force when being inserted by idler wheel convenient for sleeve body, sliding is flexible and convenient, lubricating oil is added to sponge strip by oil nozzle,
Its surface is applied in idler wheel rotary course can reduce abrasion, and ball can play certain when installing sleeve body
Booster action is easily installed.
Detailed description of the invention

Fig. 2 is the top view of Fig. 1 described in the utility model；
Fig. 3 is enlarged diagram at A described in the utility model.
In figure: sleeve body 1, dovetail groove 2, righting strip 3, trapezoid block 4, tapped blind hole 5, tapped through hole 6, bolt 7, rotation
Bar 8, idler wheel 9, ball 10, sponge strip 11, pipeline 12, oil nozzle 13.
Specific embodiment
The utility model is described in further detail with specific embodiment with reference to the accompanying drawing:
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of auto-strengthening casing, including sleeve body 1,1 outer wall of described sleeve pipe ontology hang down
Multiple dovetail grooves 2 are directly equipped with, 2 uniform array of dovetail groove is equipped with and its company of sliding in 1 surrounding of sleeve body, dovetail groove 2
The trapezoid block 4 connect, righting strip 3 is fixed on the trapezoid block 4, and the trapezoid block 4 is equipped with multiple tapped blind holes 5, casing sheet
Multiple tapped through holes 6 corresponding with tapped blind hole 5 are equipped in body 1, in the tapped blind hole 5 and corresponding tapped through hole 6
It is threaded with bolt 7.
3 inner wall of righting strip is arc and is bonded with the outer wall of sleeve body 1.
It is horizontal in the righting strip 3 to be equipped with the swingle 8 for rotating connection, it is fixed with and righting strip 3 between swingle 8
Rotate the idler wheel 9 of connection.
1 inner wall of described sleeve pipe ontology is equipped with multiple balls 10 for rotating connection.
The sponge strip 11 fixed with righting strip 3 is equipped in the idler wheel 9, the interior of the righting strip 3 is equipped with and sponge strip 11
