As shown in fig. 1 to 6, the present embodiment provides a translating electromagnetic shield door, including: the door comprises a door leaf 1, a door frame 2 and a pair of symmetrically distributed opening and closing mechanisms which are suitable for opening and closing the door leaf 1 and the door frame 2; it should be noted that a pair of opening and closing mechanisms are perpendicular to the top and bottom ends of the doorframe 2. The overall length of the door frame 2 is twice the overall length of the door leaf 1, and a half of the overall length of the door frame 2 is an open entrance, so that the door leaf 1 can be completely opened relative to the entrance of the door frame 2 to open the entrance of the door frame 2 in the process of translational motion of the door leaf 1 relative to the door frame 2. The length for the door frame 2 and the door leaf 1 is defined here in particular as the dimension perpendicular to the direction of movement of the door frame 2.

Because a pair of opening and closing mechanisms are symmetrically arranged, a detailed structure of an opening and closing mechanism is described in detail below by way of example, the opening and closing mechanism includes a push rod 11 disposed on the door leaf 1, a pair of movable sliders 12 respectively disposed on the top end and the bottom end of the push rod 11, and a pair of limit shafts 13 connected to the pair of movable sliders 12 in a one-to-one correspondence manner. The limiting shaft 13 is here arranged parallel to the push rod 11.

The pushing rod 11 is connected with the door leaf 1 in a matching way through a bearing body, so that the pushing rod 11 can rotate relative to the door leaf 1; the movable sliding block 12 is fixedly connected with the push rod 11, so that the movable sliding block 12 can perform synchronous rotary motion in the rotating process of the push rod 11; the limiting shaft 13 is in running fit with the movable sliding block 12, so that the limiting shaft 13 cannot synchronously rotate in the rotating process of the movable sliding block 12.

On the basis of the above structure, the translational electromagnetic shielding door of the present embodiment is provided with a pair of slide rails 21 on the door frame 2, wherein the slide rails 21 are adapted to be in one-to-one corresponding sliding fit with the pair of limiting shafts 13, and the pair of slide rails 21 are respectively arranged corresponding to the top and the bottom of the door frame 2. It should be noted that the sliding track 21 extends along the entire length of the door frame 2, so that the door leaf 1 can move along the guiding track to open the door opening of the door frame 2 completely. And the limiting shaft 13 is provided with a roller 15 in sliding fit with the sliding rail 21, so that the sliding fit relationship between the limiting shaft 13 and the sliding rail 21 is realized through the roller 15, that is, the limiting shaft 13 is matched with the roller 15 and the sliding rail 21 to realize the limitation of the door leaf 1 in the translation process relative to the door frame 2, and the limiting shaft plays a role of a guide rail of a translation electromagnetic shielding door used in the prior art.

It should be noted that the translational electromagnetic shielding door of the present embodiment further includes a shielding unit disposed between the door leaf 1 and the door frame 2. The shielding unit comprises a slotting tool 4 arranged at the opening edge of the door frame 2 and a slotting tool 5 arranged at the edge of the door leaf 1 suitable for being matched with the opening edge of the door frame 2 and suitable for being inserted by the slotting tool 4; namely, the shielding cooperation effect between the door leaf 1 and the door frame 2 is realized through the cooperation of the slotting tool 4 and the slotting tool 5.

Furthermore, in the present embodiment, the rotation motion of the pushing rod 11 is realized by a structure that, because the translational electromagnetic shielding door of the present embodiment includes a pair of opening and closing mechanisms, in view of the simplification of the structure, the door leaf 1 of the present embodiment is further provided with a driving component adapted to simultaneously drive the pushing rods 11 included in the pair of opening and closing mechanisms to rotate.

Referring to the drawings, an alternative embodiment is illustrated, in which the driving assembly includes a pair of movable joints 16 respectively sleeved on the pair of pushing rods 11, a pair of movable connecting rods 17 respectively connected to the pair of movable joints 16 in a one-to-one correspondence, and a rotating wheel 18 connected to both the pair of movable connecting rods 17. One pair of movable links 17 are arranged in parallel. In view of convenience of operation, a manual turn plate 19 is attached to the turning wheel 18 here.

On the basis of the structure, the push-pull effect on the pair of movable connecting rods 17 is realized through the rotation of the rotating wheel 18, when the pair of movable rods relatively move away, the pair of movable connecting rods 17 realize the rotation of the pair of push rods 11 through the movable joints 16, the synchronous motion of the movable sliding blocks 12 is realized in the rotating process of the push rods 11, and due to the sliding fit of the limiting shafts 13 connected with the movable sliding blocks 12 and the sliding rails 21 on the doorframe 2, the movable sliding blocks 12 drive the door leaf 1 to be closed towards the direction of the doorframe 2 along with the push rods 11 in the synchronous motion process of the push rods 11, so that the relative closing between the door leaf 1 and the doorframe 2 is realized. When the pair of movable rods move relatively close to each other, the pair of movable connecting rods 17 rotate the pair of push rods 11 through the movable joints, synchronous movement of the movable sliding blocks 12 is achieved in the rotating process of the push rods 11, and due to the sliding fit between the limiting shafts 13 connected with the movable sliding blocks 12 and the sliding rails 21 on the doorframe 2, the movable sliding blocks 12 drive the door leaf 1 to move towards the direction far away from the doorframe 2 along with the push rods 11 in the synchronous movement process of the push rods 11, so that relative opening between the door leaf 1 and the doorframe 2 is achieved.

In this specification, the schematic representations of the terms are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations can be made by the worker in the light of the above teachings without departing from the spirit of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
