Background
The nitrogen spring is a novel elastic component using high-pressure nitrogen as a working medium, and has the advantages of small volume, large elasticity, long stroke, stable work and the like. Original nitrogen gas spring sets up its inflation valve in nitrogen gas spring's cylinder bottom, fill in the air cavity in its cylinder and supply nitrogen gas, then only aerify when being convenient for make for the first time like this, when installing fixed back to nitrogen gas spring, use the atmospheric pressure in the nitrogen gas intracavity when not enough after the certain time, if need continue when aerifing to its nitrogen gas intracavity, need dismantle whole nitrogen gas spring get off, then just can aerify it, bring the puzzlement for the user like this, and original nitrogen gas spring is more troublesome when the installation, bring inconvenience for the user.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough that current nitrogen gas spring nitrogen gas filling process is complicated, wastes time and energy, the utility model provides a nitrogen gas spring convenient to aerify sets up its inflation hole on the piston rod, and from the piston rod side even back, the inflation hole passes through the inflation valve and connects, and the exit sets up the shield.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a nitrogen spring convenient to aerify, includes the cylinder section of thick bamboo, has seted up interior chamber in the cylinder section of thick bamboo, and the piston rod is worn to be equipped with on indoor uide bushing and the uide bushing of being equipped with of interior chamber, the hole of aerifing has been seted up to piston rod inside, it is fixed to aerify the outside port department of hole through the inflation valve jam, the mounting hole that is used for connecting the shield is seted up in the outer port department of the hole.
Furthermore, the air cylinder comprises an inflation hole which is arranged inside the piston rod, one end of the inflation hole is communicated with the inner cavity of the air cylinder barrel through the piston rod, and the other end of the inflation hole penetrates out of the side face of the middle part of the piston rod and is communicated with the outside.
Furthermore, an inflation valve fixing hole is formed in the position, located on the outer side face of the piston rod, of the inflation hole.
Furthermore, the end part of the fixing hole of the inflation valve is connected with the mounting hole.
Furthermore, a sealing ring is arranged at the bottom end of the dustproof cover, and the dustproof cover is in threaded fit connection with the mounting hole.
Furthermore, the thickness of the dustproof cover is smaller than the depth of the mounting hole.
The beneficial effects of the utility model are that, the utility model discloses a nitrogen spring convenient to aerify, aerify the hole setting with it on the piston rod, even go out the back from the piston rod side, aerify the hole and pass through the inflation valve and connect, and the exit sets up the shield, should aerify the setting in hole when nitrogen gas is filled, directly aerify from the hole of aerifing of piston rod side, need not to dismantle whole nitrogen spring and carry out nitrogen gas from its cylinder bottom portion and fill, this structure sets up simply, convenient and fast, staff's work efficiency has been improved, and convenient use.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a partially enlarged view of fig. 1A.
In the figure, 1, a cylinder barrel, 2, an inner chamber, 3, a guide sleeve, 4, a piston rod, 5, an inflation hole, 6, an inflation valve, 7, a dust cover, 8, a mounting hole, 9, an inflation valve fixing hole and 10, a sealing ring.
Detailed Description
Fig. 1 is the utility model discloses a structural schematic diagram, a nitrogen spring convenient to aerify, including cylinder barrel 1, interior chamber 2 has been seted up in cylinder barrel 1, is equipped with piston rod 4 on uide bushing 3 and the uide bushing 3 in the interior chamber 2, hole 5 has been aerifyd to inside having seted up of piston rod 4, it is fixed to block up through inflation valve 6 in the outside port department of hole 5 aerifyd, the mounting hole 8 that is used for connecting shield 7 is seted up in 5 outer port departments of hole.
Referring to fig. 1 and 2, the inflation hole 5 is disposed inside the piston rod 4, one end of the inflation hole is communicated with the inner chamber 2 of the cylinder tube 1 through the piston rod 4, and the other end of the inflation hole 5 penetrates out of the side surface of the middle portion of the piston rod 4 and is communicated with the outside. The inflation valve fixing hole 9 is arranged at the outer side surface of the piston rod 4 of the inflation hole 5. The end part of the inflation valve fixing hole 9 is connected with the mounting hole 8. The bottom end of the dustproof cover 7 is provided with a sealing ring 10, and the dustproof cover 7 is in threaded fit connection with the mounting hole 8. The thickness of the dust cover 7 is smaller than the depth of the mounting hole 8, the threads of the dust cover 7 rotate into the mounting hole 8 and are submerged into the whole mounting hole 8, the phenomenon that the dust cover 7 protrudes to influence the normal piston motion of the piston rod 4 is avoided, and meanwhile, the dust cover 7 plays a role in preventing dust and protecting the inflation valve 6.
