Abstract
The utility model discloses a kind of internal guiding nitrogen gas springs, including cylinder body, top on the cylinder body is provided with plunger, the plunger is through cylinder body and extends to inside it, the cylinder body is internally provided with piston rod, the piston rod runs through plunger and extends to its inside to be slidably connected with it, and the surface of the piston rod offers the sliding slot being used cooperatively with sealing ring.The inside is oriented to nitrogen gas spring, makes reduction piston rod guiding frictional force small by the way that sliding slot is arranged, so that frictional heat is few, effectively prevent abrasion, the damage of piston rod, greatly improve nitrogen gas spring long service life.
Description
Technical field
The utility model belongs to nitrogen gas spring technical field, and in particular to a kind of internal guiding nitrogen gas spring.
Background technique
Nitrogen gas spring (abbreviation punch die nitrogen gas spring or nitrogen gas spring or nitrogen cylinder or nitrogen cylinder) is a kind of
The novel elastic component of working media, it is small in size, elastic force is big, stroke is long, stable working, and manufacture is accurate, long service life (one
Million times), spring curve is gentle, and do not need preload etc., it has the common elastics groups such as metal spring, rubber and air cushion
Part is difficult to the work completed, and simplifies mold design and manufacture, facilitates mold installation and adjustment, extend the service life of mold, really
The stabilization for protecting product quality, can also be designed to that a kind of nitrogen gas spring system, a part as mold are worked, Ke Yi
It easily realizes that pressure is constant and deferred action in system, is a kind of optimal elastic portion of a new generation with flex capability
Part, but moving back and forth due to piston rod during use, be easy to cause the abrasion of piston rod, so that service life subtracts
Lack, is oriented to nitrogen gas spring inside a kind of so needing to design to solve the problems, such as this.
Utility model content
The purpose of this utility model is to provide a kind of internal guiding nitrogen gas springs, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of internal guiding nitrogen gas spring, including cylinder
Body, the top on the cylinder body are provided with plunger, and the plunger is through cylinder body and extends to inside it, and the inside of the cylinder body is set
It is equipped with piston rod, the piston rod runs through plunger and extends to its inside to be slidably connected with it, and the surface of the piston rod opens up
There is the sliding slot being used cooperatively with sealing ring.
This setting makes reduction piston rod guiding frictional force small using sliding slot, so that frictional heat is few, effectively prevent living
Abrasion, the damage of stopper rod, greatly improve nitrogen gas spring long service life.
Preferably, the position of the sealing ring and close sliding slot is provided with the cunning pearl being used cooperatively with sliding slot.
The technical effect and advantage of the utility model: the inside is oriented to nitrogen gas spring, to reduce work by the way that sliding slot is arranged
It is small that stopper rod is oriented to frictional force, so that frictional heat is few, effectively prevent abrasion, the damage of piston rod, greatly improving nitrogen gas spring makes
It is long with the service life.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure: 1 cylinder body, 2 plungers, 3 piston rods, 4 sealing rings, 5 sliding slots.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provide it is as shown in Figure 1 it is a kind of it is internal be oriented to nitrogen gas spring, including cylinder body 1, on the cylinder body 1
Top be provided with plunger 2, the plunger 2 is through cylinder body 1 and extends to inside it, and the cylinder body 1 is internally provided with piston
Bar 3, the piston rod 3 through plunger 2 and extend to its it is internal is slidably connected with it, the surface of the piston rod 3 offer and
The sliding slot 5 that sealing ring 4 is used cooperatively.
Specifically, the position of the sealing ring 4 and close sliding slot 5 is provided with the cunning pearl being used cooperatively with sliding slot 5.
The inside is oriented to nitrogen gas spring, when in use, by being provided with sliding slot 5 inside it, thus at work, piston
It is small that it is oriented to frictional force when bar 3 moves back and forth, so that frictional heat is few, effectively prevent abrasion, the damage of piston rod 3, greatly improves
Nitrogen gas spring long service life.
Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention, it is not limited to this
Utility model, although the utility model is described in detail with reference to the foregoing embodiments, for those skilled in the art
For, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic
It is equivalently replaced, within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
