Disclosure of Invention
An object of the utility model is to provide a simple structure is compact to prior art's not enough, has noise control buffering telescopic link of noise control buffer function.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides a pair of noise control buffering telescopic link, it includes mounting, elastic component, amortization external member and telescopic link, amortization external member cladding is in the elastic component, the mounting cup joints outside the amortization external member, the telescopic link slides and sets up in the amortization external member, the elastic component cover is located outside the telescopic link, the telescopic link runs through the amortization external member, the protruding one end of stretching out the amortization external member of telescopic link is provided with first stop piece, the protruding other end of stretching out the amortization external member of telescopic link is provided with the second stop piece.
Wherein, the elastic component is the spring, and the one end of spring is contradicted with the one end of amortization external member, and the other end of spring is contradicted with the other end of amortization external member.
The fixing piece is a metal piece or a PU elastic body.
Wherein, the amortization external member is the PU elastomer.
The first stopping piece and the second stopping piece are both PU elastic bodies.
The telescopic rod is provided with a connecting piece used for being connected with a cushion of an external chair, and the second stopping piece is located between the connecting piece and the silencing external member.
The utility model has the advantages that:
in practical application, the fixing member is fixedly connected with an external seat, one end of the telescopic rod is connected with the supporting rod at the bottom of the seat, and the other end of the telescopic rod is connected with the cushion frame of the seat; when the chair tilts up, the included angle between the backrest frame and the seat cushion frame is reduced or increased, so that the seat cushion frame drives the telescopic rod to stretch until the first stopping piece or the second stopping piece is abutted against the silencing external member; when the first stopping piece or the second stopping piece is abutted against the silencing external member, the contact between the first stopping piece or the second stopping piece and the silencing external member can be buffered to a certain extent under the action of the elasticity of the elastic member, so that the impact force generated by the collision between the first stopping piece and the silencing external member is reduced, the vibration of the seat is reduced, and the riding comfort of a user is improved; meanwhile, under the silencing effect of the silencing external member, when the first stopping member or the second stopping member collides with the silencing external member, the effect of eliminating noise can be achieved, so that the seat achieves the silencing effect, and the comfort of a user is further improved.

Detailed Description
In order to facilitate understanding of those skilled in the art, the present invention will be further described with reference to the following examples and drawings, which are not intended to limit the present invention. The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, the utility model provides a pair of noise control buffering telescopic link, it includes mounting 1, elastic component 3, amortization external member 2 and telescopic link 4, the cladding of amortization external member 2 is in elastic component 3, mounting 1 cup joints outside amortization external member 2, telescopic link 4 slides and sets up in amortization external member 2, elastic component 3 cover is located outside telescopic link 4, telescopic link 4 runs through amortization external member 2, the protruding one end of stretching out amortization external member 2 of telescopic link 4 is provided with first stop 41, the protruding other end of stretching out amortization external member 2 of telescopic link 4 is provided with second stop 42.
In practical application, the fixed part 1 is fixedly connected with an external seat, one end of a telescopic rod 4 of the fixed part is connected with a supporting rod at the bottom of the seat, and the other end of the telescopic rod 4 is connected with a seat cushion frame of the seat; when the chair tilts up, the included angle between the backrest frame and the seat cushion frame is reduced or increased, so that the seat cushion frame drives the telescopic rod 4 to stretch until the first stopping piece 41 or the second stopping piece 42 is abutted against the silencing external member 2; when the first stopping member 41 or the second stopping member 42 abuts against the silencing external member 2, the elastic force of the elastic member 3 can make the contact between the first stopping member 41 or the second stopping member 42 and the silencing external member 2 buffered to a certain extent, so as to reduce the impact force of the collision between the two members, thereby reducing the vibration of the seat and improving the riding comfort of the user; meanwhile, under the silencing effect of the silencing external member 2, when the first stopping member 41 or the second stopping member 42 collides with the silencing external member 2, the effect of eliminating noise can be achieved, so that the seat can achieve the silencing effect, and the comfort of the user can be further improved.
Specifically, the fixing member 1 is a metal member or a PU elastomer, and in this embodiment, the fixing member is preferably a PU elastomer; the silencing external member 2 is a PU elastomer; the first stopper 41 and the second stopper 42 are both made of PU elastomers. The fixing member 1 is a hard PU elastomer, and the noise reduction kit 2, the first stopper 41 and the second stopper 42 are soft PU elastomers. PU elastomer has syllable-dividing, shock attenuation and thermal-insulated effect, is particularly suitable for being used for in this structure, and PU elastomer low price, and then makes the utility model discloses a manufacturing cost is lower.
