High hardness and high antiwear performanceGood performance, not easy to cause seizure, good casting performance and cutting processing performance, and good corrosion resistance in atmosphere and fresh water. Under the condition of lacking lubricant and using water lubricant, it has good sliding property and self-lubricating property, easy cutting, poor casting property and good corrosion resistance to dilute sulphuric acid. The existing copper sleeves are not enough in hardness, and the copper sleeves are easy to deform due to long-time work.
Disclosure of Invention
To the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem that a high rigidity copper sheathing is provided to it is lower to solve present copper sheathing hardness, the problem of easy deformation.
In order to solve the technical problem, the utility model discloses a technical scheme be:
the utility model provides a high rigidity copper sheathing, includes bottle, bottle lid, stop collar, spring and fixed block, includes first main part, second main part, enhancement layer and adapter sleeve, first main part surface evenly is provided with the connecting block, and first main part and connecting block design as an organic whole, the first main part outside is provided with the enhancement layer, and is provided with the second main part outside the enhancement layer, evenly set up porosely on the enhancement layer, second main part internal surface evenly is provided with the spread groove, the upper and lower both ends of second main part all are provided with the external screw thread, both ends are provided with the adapter sleeve about the second main part.
Further, the inner side of the first main body is uniformly provided with oil grooves.
Further, the material of the reinforcing layer is iron.
Furthermore, the positions of the connecting blocks and the holes correspond to those of the connecting grooves, and the number of the connecting blocks and the holes is consistent.
Further, the diameter of the connecting block is slightly smaller than the inner diameter of the hole and the connecting groove, and the connecting block can be matched with the connecting groove.
Furthermore, the inner surface of the connecting sleeve is provided with 2 internal threads, and the connecting sleeve is in threaded connection with the second main body.
Has the advantages that: compared with the prior art, the method has the following advantages:
the high-hardness copper sleeve is provided with the reinforcing layer, so that the overall hardness of the copper sleeve is improved, and the copper sleeve is not easy to deform due to long-time work.

fig. 2 is a plan view of the high hardness copper bush.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and 2, the high-hardness copper sleeve of the present application includes a first main body 1, a second main body 2, a reinforcing layer 3 and a connecting sleeve 4, wherein the outer surface of the first main body 1 is uniformly provided with connecting blocks 101, the first main body 1 and the connecting blocks 101 are designed as a whole, the connecting blocks 101 are used for connecting the reinforcing layer 3 and the second main body 2, so as to prevent the copper sleeve from slipping during operation, the connecting blocks can be just embedded in holes 301 and connecting grooves 201 of the reinforcing layer 3, so that the connecting blocks 101 are not easy to fall off, the uniform arrangement of the connecting blocks 101 can enable the first main body 1, the reinforcing layer 3 and the reinforcing layer 3 to be connected with the second main body 2 more rapidly and stably, the reinforcing layer 3 is arranged outside the first main body 1, the second main body 2 is arranged outside the reinforcing layer 3, only the reinforcing layer 3 is arranged between the first main body 1 and the second main body 2, the, iron and tungsten copper alloy hardness, and tungsten copper alloy's radiating effect is better, be difficult to warp, evenly set up porose 301 on the enhancement layer 3, 2 internal surfaces of second main part evenly are provided with spread groove 201, the upper and lower both ends of second main part 2 all are provided with the external screw thread, both ends are provided with adapter sleeve 4 about the second main part 2, after first main part 1 and enhancement layer 3 and second main part 2 mutually support, connect adapter sleeve 4 through the screw thread, tightly fix first main part 1 and enhancement layer 3 and second main part 2 together, can not appear becoming flexible.
1 inboard oil grooves that evenly are provided with of first main part guarantees to normally let in lubricating oil in the oil groove, effectively reduces the friction, and reducing wear improves the life-span.
The material of enhancement layer 3 is iron, and the material that enhancement layer 3 can be for iron also can be the tungsten copper alloy, all has the improvement on iron and the tungsten copper alloy hardness, has strengthened the bulk hardness of copper sheathing, and the radiating effect of tungsten copper alloy is better moreover, is difficult to warp.
The connecting blocks 101 correspond to the holes 301 and the connecting grooves 201 in position and are consistent in number, so that the connecting blocks 101 can be smoothly connected with the connecting grooves 201 through the holes 301, and the stability of the first main body 1, the reinforcing layer 3 and the second main body 2 is guaranteed.
The diameter of connecting block 101 slightly is less than the internal diameter in hole 301 and connecting groove 201, and connecting block 101 can cooperate with connecting groove 201, and the connecting block has just can be inlayed with connecting groove 201 in the hole 301 of enhancement layer 3, makes connecting block 101 be difficult to drop, and the even setting of connecting block 101 can make first main part 1 be connected more anxious stable with enhancement layer 3 and second main part 2.
The inner surface of the connecting sleeve 4 is provided with internal threads, the number of the connecting sleeves 4 is 2, the connecting sleeves 4 are in threaded connection with the second main body 2, after the first main body 1, the reinforcing layer 3 and the second main body 2 are matched with each other, the connecting sleeves 4 are connected through the threads, the first main body 1, the reinforcing layer 3 and the second main body 2 are tightly fixed together, and looseness cannot occur.
The utility model provides a thinking and implementation method of high rigidity copper sheathing, the concrete application way is many, only above is the utility model discloses an optimal implementation mode should point out, to this technical field's ordinary skilled person, is not deviating from the utility model discloses under the prerequisite of principle, can also make a plurality of improvements, these improvements should also be regarded as the utility model discloses a protection scope.
