Abstract
The invention discloses an anti-noise spring which is applied to automobile seats. The spring comprises a spring body formed through integral bending, wherein the two ends of the spring body are provided with hooks; and protective sleeves are arranged outside the hooks and made of rigid plastics. The spring has the following beneficial effects: the plastic protective sleeves are arranged on the hooks at the two ends of the spring body, so that the plastic protective sleeves rub the metal frame when the seats are stressed, thus avoiding noises, and the plastic protective sleeves have certain protection effects on the hooks of the spring. The spring not only has simple structure and lower cost, but also avoids noises when in use and has long service life.
Description
Technical field
The present invention relates to a kind of spring, particularly relate to a kind of noise-proofing spring that is used for the car seat.
Background technique
At present; various springs are by extensively in being used in industrial production and large-tonnage product; the vehicle seat of automobile for example; in order to increase the comfort level that people use; the capital is provided with many with spring on seat and backrest; utilize the deformation of spring to cooperate the action of human body to reach easy to use; comfortable effect; but; traditional saddle springs generally all is to be formed by the bending of steel wire one, comprises the hook at spring body and body two ends, utilizes hook that spring is arranged on the Steel Support of vehicle seat; like this when vehicle seat is stressed; can produce a bigger friction on hook and the vehicle seat support, send bigger noise through regular meeting, and the friction of hook and vehicle seat support also can cause bigger infringement to spring; time has been grown hook is fractureed, and causes spring to use.
Summary of the invention
The object of the present invention is to provide a kind of noise-proofing spring, it has simple in structure, and cost is lower, uses the characteristics of noise free generation and long service life.
The objective of the invention is to be achieved through the following technical solutions:
A kind of noise-proofing spring, it comprises the spring body that the one bending forms, and the two ends of described spring body are provided with hook, and wherein, the outside of described hook all is arranged with protecting jacket.
Described protecting jacket is a rigid plastics.
Beneficial effect of the present invention is; described noise-proofing spring is provided with plastic protective sleeve on the hook at spring body two ends; like this when vehicle seat is stressed; plastic protective sleeve and metal frame friction avoided the generation of noise, and plastic protective sleeve play a protective role to spring carrier arm also; not only simple in structure; cost is lower, and uses noise free to produce long service life.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the structural representation of noise-proofing spring of the present invention;
Fig. 2 is the side view of noise-proofing spring of the present invention.
Among the figure:
