Utility model content
In view of the defect of the above-mentioned prior art, the purpose of this utility model is that：There is provided a kind of power preferably has machine
The novel gas spring of tool spring.
The technical solution of the utility model is：A kind of novel gas spring with mechanical spring, includes the cylinder with inner cavity
Body, the piston for being arranged in cylinder body and being slidably matched with inboard wall of cylinder block are fixed with one end of piston and for pushing piston to translate
Piston rod and be arranged in the rear stifled of rear end of the cylinder block, the bottom end of the piston rod is inserted into cylinder body, and piston bush is in piston rod
Bottom end, piston rod top is connected with nylon ball head, is equipped with the guiding of set on the piston rod in the cylinder body successively from top to bottom
Set, sealing element, spacer, stifled inner end is equipped with a compression spring for being accommodated in cylinder body bottom end after described, and a corrugated flexible hose, wave are cased with outside compression spring
The bottom end of line hose is connect with rear stifled inner end, and steel wire is equipped between the top of corrugated flexible hose and the bottom end of piston rod.
Further, there is bulge loop, one end and the bulge loop of steel wire to fix on the top of the corrugated flexible hose, the other end and piston
Bar bottom is fixed.
Further, the steel wire is two.
Further, the mode that the bottom of the corrugated flexible hose and compression spring is connected through a screw thread and rear stifled connection.
Using a kind of novel gas spring with mechanical spring provided by the utility model, advantage is：In blocking up afterwards
End is equipped with a compression spring for being accommodated in cylinder body bottom end, and a corrugated flexible hose is cased with outside compression spring, and the bottom end of corrugated flexible hose connects with stifled inner end afterwards
It connects, steel wire is equipped between the top of corrugated flexible hose and the bottom end of piston rod, it can will be under compression spring when piston rod is reduced to cylinder body bottom end
Pressure, when piston rod stretches out, compression spring can give one impulse force of piston rod, keep piston rod power sufficient, corrugated flexible hose plays positioning compression spring
Effect, prevent compression spring double swerve, after hose is compressed by cylinder body, piston rod stretch out when hose is resetted by steel wire, tie
Structure is simple and easy to use.
Description of the drawings
Fig. 1 is the overall structure diagram of the utility model.
As shown in the figure：1-cylinder body, 1.1-inner cavities, 2-pistons, 3-piston rods, 4-is rear stifled, 5-nylon ball heads, and 6-
Guide sleeve, 7-sealing elements, 8-spacers, 9-compression springs, 10-corrugated flexible hoses, 101-bulge loops, 11-steel wires.
Specific implementation mode
For it is relatively intuitive, be fully understood by the technical solution of the utility model, now just combine the progress of the utility model attached drawing
Unrestricted feature description is as follows：
As shown in Figure 1, a kind of novel gas spring with mechanical spring, includes the cylinder body 1 with inner cavity 1.1, is arranged in cylinder body 1
It is interior and be slidably matched with 1 inner wall of cylinder body piston 2, fix with one end of piston 2 and the piston rod 3 for pushing piston 2 to translate
And be arranged rear stifled the 4 of 1 rear end of cylinder body, the bottom end of piston rod 3 is inserted into cylinder body 1, and piston 2 is sleeved on the bottom end of piston rod 3,
3 top of piston rod is connected with nylon ball head 5, is equipped with the guide sleeve 6 being sleeved on piston rod 3, sealing in cylinder body 1 successively from top to bottom
Part 7, spacer 8, rear stifled 4 inner ends are equipped with a compression spring 9 for being accommodated in 1 bottom end of cylinder body, a corrugated flexible hose 10, ripple are cased with outside compression spring 9
The bottom end of hose 10 is connect with rear stifled 4 inner ends, and steel wire 11 is equipped between the top and the bottom end of piston rod 3 of corrugated flexible hose 10.
There is bulge loop 101, one end and the bulge loop 101 of steel wire 11 to fix on the top of corrugated flexible hose 10, the other end and piston rod 3
Bottom is fixed.Piston rod 3 is facilitated to push down hose.
Steel wire 11 is two.When the bottom end of piston rod 3 moves to 1 top of cylinder body and can not stretch out again, 11 quilt of steel wire
Stretch, prevent 11 length of steel wire it is long cause hose can not be stretched reset the case where occur.
