The second level resets compressed spring and is located between third graphite guide sleeve and the second annular outer platform；Second annular outer platform upper end that
It is fixed with the 4th graphite guide sleeve with one heart on section inner cylinder outer wall, is touched between the 4th graphite guide sleeve outer wall and outer barrel inner wall in virtual connection.
The upper end of the compression bar is fixed with load pressure head with one heart.
The compressing force that the level-one resets compressed spring is less than the compressing force that second level resets compressed spring.
The above scheme has the following advantages:
Due to being arranged concentrically inner cylinder in the outer barrel of the two-level spring compression sleeve of the utility model, the two of inner cylinder
End is opening-like, and between compression bar and outer barrel, and in sliding shape cooperation between compression bar and inner cylinder, level-one resets presses inner cylinder
Contracting spring in sliding shape cooperation between inner cylinder and outer barrel, and has second level to reset compression between compression bar and inner cylinder between the two
Spring.This spring-compressed sleeve utilizes the cooperation of compression bar and inner cylinder, inner cylinder and outer barrel, can carry out second level and stretch, with
Background technique is compared, and in the case where barrel lenght is certain, can greatly prolong compression travel, so that the height of press is reduced,
Reduce manufacturing cost, and widens the use scope of press.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the two-level spring compression sleeve of the utility model；
Fig. 2 is structural schematic diagram of the two-level spring compression sleeve of the utility model under level-one stretching state；
Fig. 3 is structural schematic diagram of the two-level spring compression sleeve of the utility model under second level stretching state.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
As shown in Figure 1, the two-level spring compression sleeve of the utility model includes the outer barrel 1 in vertical, outer barrel 1
Both ends it is opening-like, compression bar 4 and level-one have been arranged concentrically in outer barrel 1 and has resetted compressed spring 5.It is same in the outer barrel 1
The heart is provided with inner cylinder 3, and the both ends of inner cylinder 3 are opening-like, inner cylinder 3 between compression bar 4 and outer barrel 1, and compression bar 4 with
In sliding shape cooperation between inner cylinder 3, the level-one resets compressed spring 5 between compression bar 4 and inner cylinder 3.The inner cylinder 3 with
In sliding shape cooperation between outer barrel 1, and there is second level to reset compressed spring 2 between the two.
Annular gasket 13 is fixed in the lower part of the inner cylinder 3 with one heart, is matched between compression bar 4 and annular gasket 13 in sliding shape
It closes, there is the first annular outer lug boss 10 projected radially outwardly on the compression bar 4 of 13 top of annular gasket, the level-one resets compression bullet
Spring 5 is between annular gasket 13 and first annular outer lug boss 10.
For the ease of sliding, it is fixed with the first graphite with one heart on that section of compression bar 4 of first annular 10 top of outer lug boss
Guide sleeve 7 is touched in virtual connection between 3 inner wall of outer wall and inner cylinder of first graphite guide sleeve 7.That section of inner cylinder of 13 lower section of annular gasket
The second graphite guide sleeve 12 is fixed on body 3 with one heart, is in virtual connection between the outer wall of the compression bar 4 and the inner wall of the second graphite guide sleeve 12
Touching.Third graphite guide sleeve 11,3 outer wall of inner cylinder and third graphite guide sleeve are fixed in the lower part of the outer barrel 1 with one heart
It is touched between 11 inner walls in virtual connection, has the second annular projected radially outwardly outer on 3 outer wall of inner cylinder of 11 top of third graphite guide sleeve
Boss 9, the second level reset compressed spring 2 and are located between third graphite guide sleeve 11 and the second annular outer platform 9；Second annular outer
The 4th graphite guide sleeve 6,6 outer wall of the 4th graphite guide sleeve and outer barrel 1 are fixed on 3 outer wall of that section of inner cylinder of 9 upper end of platform with one heart
It is touched between inner wall in virtual connection.
For the ease of load, the upper end of the compression bar 4 is fixed with load pressure head 8 with one heart.
The compressing force that the level-one resets compressed spring 5 is less than the compressing force that second level resets compressed spring 2.
In use, compression bar 4 is pushed by load pressure head 8 using external force, since the compressing force that level-one resets compressed spring 5 is small
The compressing force of compressed spring 2 is resetted in second level, compression bar 4 is stretched out from inner cylinder 3 along its axial direction, while being compressed level-one and being resetted compression
Spring 5 carries out level-one stretching, as shown in Fig. 2,.External force is continued to, is compressed to extreme position when level-one resets compressed spring 5
When, compression bar 4 resets compressed spring 5 by first annular outer lug boss 10, level-one, annular gasket 13 drives inner cylinder 3 protruding,
Second level is compressed simultaneously and resets compressed spring 2, carries out second level stretching, as shown in Figure 3.After external force disappears, resets and compress in level-one
Under the action of spring 5 and second level reset compressed spring 2, inner cylinder 3 and briquetting reset, as shown in Figure 1.
