Description
Technical field
The utility model is related to gas spring technology field, specifically a kind of dedusting gas spring.
Background technology
Gas spring is a kind of industry accessories that can play the functions such as support, buffering, braking, height adjusting and angular adjustment.
It is made of following sections：Pressure cylinder, piston rod, piston, seal guide sleeve, filler (inert gas or air-fuel mixture
Object), control element and cylinder outer control element (referring to controllable gas spring) and connector etc. in cylinder.Principle is filled in closed pressure cylinder
Entering inert gas, either gas mixture makes several times or tens times of the pressure superatmospheric in cavity, utilizes piston rod
Cross-sectional area realize the movement of piston rod less than the cross-sectional area of piston to the pressure difference generated.Due to the root in principle
This difference, gas spring have significant advantage than common spring：Speed is relatively slow, dynamic force change is little (generally 1：
Within 1.2), be easy to control.
Gas spring in existing use, piston rod one end are inserted into pressure cylinder, and the other end is exposed outside, such knot
Structure has the following disadvantages：Exposed piston rod cannot be protected, naked at some in the production environment of more dust
The piston rod that exposes outside is very easy to the full dust of product, and surface is stained with the piston rod of dust and can frequently rub with seal guide sleeve
It wipes, due to there is the presence of dust, the friction coefficient in friction process is big, is easy to cause piston rod and seal guide sleeve damage, institute
To need often to check and repair, when repair, carried out after also dismantling pressure cylinder, repair bothers very much, and reduces gas
The service life of spring.

The endoporus of dirt ring, the fixed ring, primary dust removing ring and two-stage dust removal ring is bonded with the outer surface of piston rod, the fixed ring
One end and pressure cylinder end on the outside of be fixedly connected, the other end be circular groove structure, and with one end of primary dust removing ring
Internal and external threads are fixedly connected, and the other end of the primary dust removing ring is also circular groove structure, and with spiral shell inside and outside two-stage dust removal ring
Line is fixedly connected.
Further, the appearance of the two-stage dust removal ring is polyurethane elastomer layer.
Further, the bore area of the primary dust removing ring and two-stage dust removal ring is coated with lubricant.
Further, the outer diameter between the two-stage dust removal ring, primary dust removing ring and fixed ring three is sequentially increased, and is in rank
Scalariform.
Further, the gap of several annular arrays distribution is opened up on the two-stage dust removal ring, and in two-stage dust removal ring
The radius of circle is less than the radius of the piston rod.
With the above structure, the utility model has the beneficial effect that：The dedusting gas spring of the utility model uses dust removal machine
Structure is arranged on the piston rod, and when in use, dedusting mechanism is arranged on the piston rod gas spring, due to the inner ring half of two-stage dust removal ring
Diameter is less than the radius of piston rod, opens up the gap of several annular arrays distribution on two-stage dust removal ring again, therefore, piston rod to
When cylinder body contract, two-stage dust removal ring can be close to the outer circumference surface of piston rod, can wipe the dust on piston rod off,
The contraction of piston rod is not influenced again while effective dedusting, and when two-stage dust removal ring is worn, you can rapidly remove two level
The new two-stage dust removal ring of dirt ring dismounting and change can also allow primary dust removing ring temporarily to substitute a period of time.

Specific implementation mode
The utility model will be further described below with reference to the accompanying drawings.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and specifically
Embodiment, the present invention will be further described in detail.It should be appreciated that the specific embodiments described herein are only used
To explain the utility model, it is not used to limit the utility model.
Referring to Fig. 1-2, a kind of dedusting gas spring, including pressure cylinder 1, piston rod 2, piston 3 and seal guide sleeve 4, piston 3
It is sealedly connected in pressure cylinder 1,2 one end of piston rod is connect with piston 3, and seal guide sleeve 4 is connected to the interior of 1 one end of pressure cylinder
Portion, piston rod 2 run through seal guide sleeve 4, and dedusting mechanism 5 is fixedly installed on the outside of the end of pressure cylinder 1, and dedusting mechanism 5 includes solid
Determine ring 51, primary dust removing ring 52 and two-stage dust removal ring 53, the endoporus of fixed ring 51, primary dust removing ring 52 and two-stage dust removal ring 53 is equal
