[0002] The electromagnetic shielding cabinet (room) is a device that uses a shell, a plate, a sleeve or other shapes of shielding bodies made of conductive or magnetically conductive materials to limit electromagnetic ability within a certain space to suppress radiation interference, and processes conduction and radiation to provide a non-interference test environment for the measured wireless communication equipment.

[0003] The electromagnetic shielding door is one of the indispensable components of the shielding cabinet (room), and the electromagnetic shielding door is divided into a hinge rotating type and a translation type. For the hinge shielding door, during the closing process of the door leaf relative to the door frame, the single-blade double-spring shielding structure between the door leaf and the door frame is matched. For the single-blade double-spring shielding structure, the vertical insertion of the double-spring shielding assembly and the blade is required. For the rotation of the door leaf relative to the door frame, the motion track of the door leaf is an arc-shaped motion, so that the arc-shaped motion track of the door leaf has a certain resistance to the vertical insertion track of the double-spring shielding assembly and the blade. Therefore, a large force is required to vertically insert the double-spring shielding assembly and the blade into place during the matching of the single-blade double-spring shielding structure between the door leaf and the door frame, so that the locking and closing operation of the door leaf relative to the door frame is inconvenient, and the closing efficiency is affected.

DETAILED DESCRIPTION

[0037] In order to make the content of the utility model more easily understood clearly, the utility model is further explained in detail below according to specific embodiments and in conjunction with the drawings.

[0038] Embodiment 1:

[0039] Please refer to Figures 1 to 5 As shown in the drawings, the embodiment provides a hinge, which comprises a fixed seat, a connecting rod 2, a guide assembly and a hinge assembly used in cooperation.

[0040] Generally, first, the fixed seat comprises a seat body 1 in the shape of a cuboid and a hollow accommodating cavity 11 formed in the seat body 1, wherein the hollow accommodating cavity 11 is also in the shape of a cuboid; and one of the lengthwise side end faces of the seat body 1 is formed with an opening communicating with the hollow accommodating cavity 11.

[0041] Secondly, the connecting rod 2 penetrates the hollow accommodating cavity 11 along the length direction of the seat body 1, and the length of the connecting rod 2 is greater than the length dimension of the seat body 1, so that the two ends of the connecting rod 2 respectively extend to the two lengthwise side end faces of the seat body 1. Based on this, the connecting rod 2 can perform a translational movement along the width direction of the seat body 1 when performing a lifting movement along the length direction of the seat body 1, and in this process, neither end of the connecting rod 2 will enter the hollow accommodating cavity 11 when the connecting rod 2 performs the lifting movement, and the overall connecting rod 2 is generally in the shape of a cylinder.

[0042] Further, the guide assembly comprises a lifting guide group arranged between the connecting rod 2 and the seat body 1, and a movable frame 3 arranged in the hollow accommodating cavity 11 and movably sleeved on the connecting rod 2, and a translational guide group arranged between the movable frame 3 and the seat body 1. Here, the connecting rod 2 can perform a translational movement along the width direction of the seat body 1 when performing a lifting movement along the length direction of the seat body 1 through the guide assembly.

[0043] More specifically, in combination with an optional case shown in the drawings, the lifting guide group comprises two pairs of waist-shaped guide holes 41 arranged in pairs on the pair of lengthwise side end faces of the seat body 1 perpendicular to the opening, and four pin shafts 42 arranged on the connecting rod 2 and adapted to be inserted into each waist-shaped guide hole 41 of the seat body 1 in one-to-one correspondence. It should be noted that the two waist-shaped guide holes 41 on each side end face of the seat body 1 are parallel to each other, and the long axis of each waist-shaped guide hole 41 is arranged in an inclined distribution with respect to the length direction of the seat body 1.

[0044] The translational guide group comprises a pair of waist-shaped positioning holes 51 arranged on the pair of lengthwise side end faces of the seat body 1 perpendicular to the opening, and a pair of positioning pin shafts 52 arranged on the movable frame 3 and adapted to be inserted into the pair of waist-shaped positioning holes 51 in one-to-one correspondence; the long axis of the waist-shaped positioning hole 51 is parallel to the width direction of the seat body 1. It should be noted that, in an optional case, the waist-shaped positioning hole 51 here is generally in the shape of a U, so that the waist-shaped positioning hole 51 has an open mouth, and the open mouth extends to the opening end face of the seat body 1.

[0045] On the basis of the above structure, it is necessary to further explain that the side wall of the movable frame 3 is further provided with a pair of waist-shaped holes 53 suitable for the four pin shafts 42 to pass through, and the long axis of each waist-shaped hole 53 is parallel to the length direction of the seat body 1. In this regard, in an alternative embodiment, the positioning pin 52 on each length direction side end surface of the movable frame 3 is located between the two waist-shaped holes 53. A waist-shaped movable hole 12 with a long axis parallel to the long axis of the waist-shaped positioning hole 51 is provided on each of the two width direction side end surfaces of the seat body 1.

[0046] In addition, it is necessary to explain that the four pin shafts 42 are evenly distributed on the two pairs of side end surfaces of the connecting rod 2, and the connecting line of the two pin shafts 42 on the same side end surface of the pin shaft 42 is parallel to the length direction of the seat body 1. The movable frame 3 is a rectangular structure; and the four waist-shaped holes 53 are evenly distributed on the two pairs of length direction side end surfaces of the movable frame 3, and the connecting line of the long axes of the two waist-shaped holes 53 on the same side end surface of the movable frame 3 is parallel to the length direction of the seat body 1.

[0047] Finally, the hinge assembly includes a connecting plate set partially inserted into the hollow movable cavity and movably sleeved on the connecting rod 2, and a gap set provided on one of the length direction side end surfaces of the seat body 1 and suitable for the connecting plate set to partially move out of the seat body 1 by rotating around the connecting rod 2.

[0048] Specifically, the connecting plate set includes a pair of connecting plates 61 inserted into the hollow accommodating cavity 11 from the opening part; the pair of connecting plates 61 are respectively provided on the two sides of the movable frame 3 along the length direction of the seat body 1. The gap set includes a pair of U-shaped grooves 62 suitable for the pair of connecting plates 61 to move one by one, which are provided on one of the length direction side end surfaces of the seat body 1 and provided with waist-shaped guide holes 41.

[0049] With reference to the above-mentioned structure of the hinge, in the case of the lifting movement of the connecting rod 2, as viewed from the perspective of the drawing, the bottom of the waist-shaped guide hole 41 is relatively far from the opening of the seat body 1, and the top of the waist-shaped guide hole 41 is relatively close to the opening of the seat body 1. In the initial state, the pin shaft 42 on the connecting rod 2 is located at the bottom of the waist-shaped guide hole 41, and the positioning pin 52 is located at the end of the waist-shaped positioning hole 51 far from the opening of the seat body 1. At this time, the insertion depth of the pair of connecting plates 61 relative to the hollow accommodating cavity 11 reaches the maximum. Based on this condition, with the lifting movement of the connecting rod 2, the pin shaft 42 on the connecting rod 2 gradually moves along the long axis direction of the waist-shaped guide hole 41 to the top of the waist-shaped positioning hole 51. At the same time, the movable frame 3 sleeved on the connecting rod 2 cannot move synchronously with the lifting movement of the connecting rod 2 due to the limiting action of the positioning pin 52. At this time, the positioning pin 52 moves along the waist-shaped positioning hole 51, and the movable frame 3 only translates along the width direction of the seat body 1, so as to move towards the opening side of the seat body 1, so that the movable frame 3 partially moves to the outside of the hollow accommodating cavity 11. Thus, the pair of connecting plates 61 located at both ends of the movable frame 3 cannot move up and down with the connecting rod 2, but can only move translationally with the connecting rod 2, so as to realize the partial movement of the pair of connecting plates 61 to the outside of the hollow accommodating cavity 11 during the movement of the pair of connecting plates 61 towards the opening side of the seat body 1. In this process, the connecting rod 2 moves translationally along the waist-shaped movement hole 12 on the seat body 1 during the lifting movement. Based on this, the pair of connecting plates 61 can be rotated around the connecting rod 2, and the pair of U-shaped grooves 62 provides the space required for the rotation of the connecting plates 61. When the connecting rod 2 moves downward, a completely opposite movement process to the above-mentioned process can be generated, which will not be described herein.

[0050] In addition, considering the need for the hinge of the present embodiment to be matched with the shielding door body 100 when it is applied to a shielding cabinet or a shielding room, the hinge set adopted in the present embodiment further comprises a hinge leaf 71 connected with the pair of connecting plates 61. The hinge leaf 71 is perpendicular to the pair of connecting plates 61. In this regard, in order to facilitate the fixation of the seat body 1 to the shielding door frame, the pair of width direction side ends of the seat body 1 are respectively provided with an outwardly turned connecting lug 72.

[0051] In summary, for the hinge of the embodiment, the connecting plate group connected with the connecting rod 2 can first translate a certain distance along the width direction of the seat body 1 and then rotate relative to the seat body 1 when the connecting rod 2 makes the lifting movement along the length direction of the seat body 1. Thus, when the hinge is applied to the specific shielding cabinet door, the shielding door body 100 adopting the hinge can first translate a certain distance to the outside of the cabinet door frame 200 and then rotate, so that the double-spring-leaf shielding assembly and the plug are separated during the translation of the shielding door body 100 relative to the cabinet door frame 200, and then the shielding door body 100 rotates relative to the cabinet door frame 200 after the double-spring-leaf shielding assembly and the plug are separated. During the closing process of the shielding door body 100, the double-spring-leaf shielding assembly and the plug are first rotated and then translated to realize the plug-in cooperation of the double-spring-leaf shielding assembly and the plug. Based on the hinge, compared with the structure of two hinge shafts in the prior art, the hinge can meet the cooperation requirements of the spring leaf and the plug of the shielding door, and can also reduce the requirement for machining precision, thereby reducing the machining difficulty.

Specifically, the seat body 1 of the hinge is assembled and fixed to the cabinet door frame 200 through a pair of connecting ears 72, and the hinge leaf 71 is fixed and assembled to the shielding door body 100. In addition, a driving assembly for driving the connecting rod 2 to make the lifting movement is arranged on the shielding door body 100.
