The electromagnetic sealing device comprises six-sided shells, doors, windows and other common house elements, only requires strict electromagnetic sealing performance, and correspondingly shields all inlet and outlet pipelines so as to block electromagnetic radiation from entering and exiting. Chinese patent CN208534362U discloses a single-blade single-slot steel plate shielding window, on one hand, the shielding single blade is buckled in the shielding single-slot, so that the sealing performance of the shielding window is better; on the other hand, when the shielding window is closed, the conductive cotton is convenient to form a conductive loop, and the electromagnetic wave can be shielded more effectively.

However, in practical application, since the electromagnetic shielding chamber is generally used for placing large-scale equipment, the volume of the shielding window is not too small, which causes the shielding window to be very laborious to open and close; and with opening and closing many times, the conductive cotton in the groove can be gradually deformed or damaged, thereby influencing the formation of a conductive circuit.

Detailed Description

The utility model is further described with reference to the following figures and examples, which are provided only for illustrating the utility model and are not intended to limit the scope of the utility model.

In the description of the present invention, it is to be understood that the terms "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the scope of the present invention.

With reference to fig. 1 to 3, a connecting structure of a shielding window and a shielding body includes a rectangular door frame 2 installed on a shielding body 1, wherein a plurality of first sliding rails 3 are arranged on one side of the rectangular door frame 2 on the shielding body 1, the first sliding rails 3 are parallel to two horizontal edges of the rectangular door frame 2, the shielding window 4 is arranged on the first sliding rails 3 through sliding blocks, and a movable plate 5 is arranged on one side of the shielding window 4 corresponding to the first sliding rails 3 through elastic components; the hinge shaft of the movable plate 5 and the shielding window 4 is perpendicular to the first slide rail 3, and the rectangular door frame 2 is provided with a groove 6 matched with the side edge of the movable plate 5.

With reference to fig. 3 and 4, a receiving groove 7 is formed in one side of the shielding window 4 corresponding to the first slide rail 3, and a vertical edge of the shielding window 4 is hinged to the bottom of the receiving groove 7; the elastic component comprises a plurality of compression springs vertically arranged on the bottom surface of the accommodating groove 7, and the tops of the compression springs are fixedly connected with the movable plate 5. Under the action of the compression spring, when the shielding window is positioned in the range of the door frame, the movable plate is positioned outside the accommodating groove 7, and at the moment, the free edge of the movable plate can extend into the groove 6 (the opening angle of the movable plate is realized by presetting the elastic force of the compression spring or arranging a stay cord with fixed length between the movable plate and the accommodating groove), so that electromagnetic shielding is formed; when the shielding window is opened (moves to the right side of the figure), the movable plate is gradually pressed into the accommodating groove, and the shielding window can cling to the shielding body to move rightwards.

Two horizontal edges of the rectangular door frame 2 are provided with two second slide rails 8 which are oppositely arranged and are parallel to the first slide rails 3, and the upper edge and the lower edge of the shielding window 4 are provided with pulleys 9 matched with the second slide rails 8, so that the shielding window can easily move along the horizontal direction.

The diameter of the pulley 9 is smaller than the depth of the second slide rail 8, so that the edge of the shielding window and the door frame have enough overlapping size, and the electromagnetic shielding effect of the shielding window is ensured.

As shown in fig. 5, a plurality of guide wheels 10 are disposed on the vertical side of the rectangular door frame 2 close to the first slide rail 3, so as to ensure the opening and closing fluency of the movable plate.

As shown in fig. 6, a shielding film 11 is connected between the vertical edge of the rectangular door frame 2 close to the first sliding rail 3 and the shielding window 4 (in practical application, the shielding film may be an elastic sheet-like structure or a folding structure similar to a folding fan, so as to ensure that the movement of the shielding window is not affected while the shielding effect of the shielding window close to one side of the sliding rail is ensured).

In addition, metal bristles (not shown in the attached drawings) are arranged in the second sliding rail 8 and the groove 6, so that on one hand, the effect of blocking sundries is achieved, and the sundries are prevented from entering the second sliding rail or the groove to influence the closing of the shielding window; on the other hand, the metal bristles can play a certain reinforcing role in the electromagnetic protection capability of the gap between the shielding window and the sliding rail or the groove, and compared with conductive cotton, the metal bristles can provide a worse working environment and have longer service life.

Therefore, the utility model is not limited to the specific embodiments and examples, but rather, all equivalent variations and modifications are within the scope of the utility model as defined in the claims and the specification.
