Description
Technical field
The utility model is related to gas spring technology field, specifically a kind of low noise gas spring.
Background technology
In the prior art, steel part is used on the piston rod of gas spring, and as crash structure, steel part is to be set in piston rod
On.Since steel part and cylinder barrel are rigid structure, transition or interference fit can not be used to be installed, need the outer diameter of steel part
Less than the internal diameter of cylinder barrel, steel part could be packed into inside cylinder barrel.Due to steel part outer diameter, there are certain difference, steel parts with internal diameter of cylinder
There are gaps between cylinder barrel, and during piston rod moves back and forth, steel part is not fixedly connected with cylinder barrel, steel part and cylinder barrel
Collision is generated between inner wall, so as to generate noise；In addition, when gas spring resets, piston rod reaches longest position, piston
The piston of boom end can collide with steel part, and when collision can also generate larger noise.
Utility model content
The purpose of this utility model is that it is in view of the drawbacks of the prior art and insufficient, a kind of low noise gas spring is provided.
To achieve the above object, the technical solution adopted in the utility model is：A kind of low noise gas spring, including cylinder barrel,
Piston rod, piston and seal guide sleeve, the piston seal are connected in cylinder barrel, and described piston rod one end is connect with piston, institute
The inside that seal guide sleeve is connected to cylinder barrel one end is stated, the piston rod runs through seal guide sleeve, and cylinder barrel is divided by the piston
Rod chamber and rodless cavity, innovative point are：Noise reduction is fixedly installed successively from left to right between the piston and seal guide sleeve
Plate, abatvoix and noise reduction soundboard, the acoustical panel are fixed on the right side of piston, and the abatvoix is fixed with noise reduction soundboard to be connected
It connects, the noise reduction soundboard is fixed on seal guide sleeve, and the piston rod sequentially passes through acoustical panel, abatvoix and noise-reducing
Plate.
Further, the right side of the acoustical panel is wavy shaped configuration, and the left side of the abatvoix is equally also waveform
Structure, but wave crest between the two is dislocatedly distributed, and the wave crest of the two cooperates.
Further, the inside fixed setting acoustical cotton of the abatvoix.
Further, the noise reduction soundboard includes rubber outline border and the air bag being fixed in rubber outline border, the gas
Capsule is sector structure, circularizes array distribution.
Further, the quantity of the air bag is at least 4.
With the above structure, the utility model has the beneficial effect that：A kind of low noise gas spring provided by the utility model,
Avoid the direct collision of piston and seal guide sleeve by the collision between acoustical panel and abatvoix, and acoustical panel and abatvoix
Between the noise that generates it is smaller, while after the noise generated is guided, is absorbed by acoustical cotton, reduce noise, and noise-reducing
Setting air bag in plate can alleviate the impact force of piston, reduce the collision shake between inner wall of cylinder and piston rod and piston
It is dynamic, reduce noise.
Description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the structure diagram of noise reduction soundboard in the utility model.
Reference sign：1 cylinder barrel, 2 piston rods, 3 pistons, 4 seal guide sleeves, 5 rod chambers, 6 rodless cavities, 7 acoustical panels,
8 abatvoixs, 81 acoustical cottons, 9 noise reduction soundboards, 91 rubber outline borders, 92 air bags.
Specific embodiment
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 is 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, a kind of low noise gas spring, including cylinder barrel 1, piston rod 2, piston 3 and seal guide sleeve 4, piston 3 is close
Envelope is connected in cylinder barrel, and 2 one end of piston rod is connect with piston 3, and seal guide sleeve 4 is connected to the inside of 1 one end of cylinder barrel, piston rod
2 run through seal guide sleeve 4, and piston 3 divides cylinder barrel 1 for rod chamber 5 and rodless cavity 6, from a left side between piston 3 and seal guide sleeve 4
It turns right and acoustical panel 7, abatvoix 8 and noise reduction soundboard 9 is fixedly installed successively, acoustical panel 7 is fixed at 3 right side of piston, abatvoix 8
Be fixedly connected with noise reduction soundboard 9, noise reduction soundboard 9 is fixed on seal guide sleeve 4, piston rod 2 sequentially pass through acoustical panel 7,
Abatvoix 8 and noise reduction soundboard 9.
In the present embodiment, the right side of acoustical panel 7 is wavy shaped configuration, and the left side of abatvoix 8 is also equally wavy shaped configuration,
But wave crest between the two is dislocatedly distributed, and the wave crest of the two cooperates.Collision between acoustical panel 7 and abatvoix 8 generates
Noise it is smaller, simultaneously because using wavy shaped configuration, the noise of generation is entered by conduction in abatvoix 8, reduces noise.
In the present embodiment, the inside fixed setting acoustical cotton 81 of abatvoix 8.Acoustical cotton 81 can effectively absorb acoustical panel
