Abstract
The utility model discloses a spring piece for an air bag door of an electromagnetic shielding chamber. The spring piece comprises a flake substrate (1), wherein the flake substrate (1) is formed by a plane plate (2), a first omega-shaped plate (3) and a second omega-shaped plate (4) which are connected into a whole; the first omega-shaped plate (3) is smoothly connected with one end of the plane plate (2); the second omega-shaped plate (4) is smoothly connected with the other end of the plane plate (2); the ends at the inner sides of the first omega-shaped plate (3) and the second omega-shaped plate (4) are respectively provided with a mounting compression joint surface (5); and three grooves (2-1) are formed on the plane plate (2) under the mounting compression joint surfaces (5). The spring piece can well guarantee the shielding performance of the electromagnetic shielding chamber.
Description
Technical field
The utility model relates to a kind of spring leaf, specifically, relates to a kind of spring leaf that is used for the electromagnetic shielding chamber air bag doors.
Background technology
At present; Electromagnetic shielding chamber all is equipped with electromagnetic shield door; It is unique passage that personnel pass in and out electromagnetic shielding chamber; And the performance that ensures the key element spring leaf of shield door shielding character directly influences the shielding properties of electromagnetic shielding chamber, and the spring leaf under the prior art condition sometimes makes the poor effect of electromagnetic shielding chamber shielding.
Summary of the invention
The purpose of the utility model provides a kind of spring leaf that is used for the electromagnetic shielding chamber air bag doors that can guarantee the shielding properties of electromagnetic shielding chamber well.
The technical scheme that realizes the utility model purpose is: a kind of spring leaf that is used for the electromagnetic shielding chamber air bag doors; Comprise flaky matrix; This flaky matrix is made up of the surface plate that fuses, a Ω shape plate and the 2nd Ω shape plate; The one Ω shape plate is held sliding the linking level with both hands with one of surface plate; The other end of the 2nd Ω shape plate and surface plate links up smoothly, and the medial end of a Ω shape plate and the 2nd Ω shape plate respectively has one crimping face is installed, and on the surface plate of locating below this installation crimping face, has three grooves.
Further, described flaky matrix is formed by the beryllium bronze band bending and molding.
Further, described groove is the waist circular trough.
After having adopted technique scheme, push down the installation crimping face of a Ω shape plate and the 2nd Ω shape plate, and pass in the groove of surface plate with three housing screws; Be screwed on the installed part; Two Ω shape shield gasket chambeies have so just been formed, after personnel get into screened room, after the translation of shielding door leaf is closed and put in place; Stretch when airbag aeration in these two Ω shape shield gasket chambeies; Closely join together, form two shield gasket contact surfaces, thereby guaranteed the shielding properties of electromagnetic shielding chamber better with the shielding door leaf.
Description of drawings
Fig. 1 is the elevation of the spring leaf that is used for the electromagnetic shielding chamber air bag doors of the utility model;
Fig. 2 is the left view of Fig. 1.
The specific embodiment
For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,
Like Fig. 1, shown in 2; A kind of spring leaf that is used for the electromagnetic shielding chamber air bag doors comprises flaky matrix 1, and this flaky matrix 1 is made up of the surface plate that fuses 2, a Ω shape plate 3 and the 2nd Ω shape plate 4; The one Ω shape plate 3 is held sliding the linking level with both hands with one of surface plate 2; The 2nd Ω shape plate 4 links up smoothly with the other end of surface plate 2, and the medial end of a Ω shape plate 3 and the 2nd Ω shape plate 4 respectively has one crimping face 5 is installed, and on the surface plate of locating below this installation crimping face 52, has three groove 2-1.
Described flaky matrix 1 is formed by the beryllium bronze band bending and molding.
As shown in Figure 1, described groove 2-1 is the waist circular trough.
The operating principle of the utility model is following:
Push down the installation crimping face 5 of a Ω shape plate 3 and the 2nd Ω shape plate 4 with three housing screws, and pass among the groove 2-1 of surface plate 2, be screwed on the installed part; Two Ω shape shield gasket chambeies have so just been formed, after personnel get into screened room, after the translation of shielding door leaf is closed and put in place; Stretch when airbag aeration in these two Ω shape shield gasket chambeies; Closely join together, form two shield gasket contact surfaces, thereby guaranteed the shielding properties of electromagnetic shielding chamber better with the shielding door leaf.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
Claims (3)
