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. 1-3, a connecting structure of a shielding door and a shielding body includes a rectangular door frame 2 installed on the shielding body 1, 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, a shielding door 4 is arranged on the first sliding rails 3 through sliding blocks, one side of the shielding door 4 corresponding to the first sliding rails 3 is hinged to a movable plate 5, a hinged shaft of the movable plate 5 and the shielding door 4 is perpendicular to the first sliding rails 3, and a groove 6 matched with the side edge of the movable plate 5 is arranged on the rectangular door frame 2.

Referring to fig. 3 and 4, a torsion spring (not shown in the drawings) is disposed on the hinge shaft of the movable plate 5 and the shield door 4, and two ends of the torsion spring are respectively connected to the movable plate 5 and the shield door 4; one side of the shielding door 4 corresponding to the first slide rail 3 is provided with a storage groove 7, and the movable plate 5 can be completely stored in the storage groove 7. Under the action of the torsion spring, when the shielding door 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 elasticity of the torsion 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 shield door is opened (moves to the right side of the figure), the movable plate is gradually pressed into the receiving groove, and at the moment, the shield door can cling to the shield 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 door 4 are provided with pulleys 9 matched with the second slide rails 8, so that the shielding door can easily move along the horizontal direction.

The diameter of the pulley 9 is smaller than the depth of the second sliding rail 8, so that the sufficient overlapping size between the edge of the shielding door and the door frame is ensured, and the electromagnetic shielding effect of the shielding door 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.
