[0002] The electromagnetic shielding door is a device that isolates electromagnetic waves. It can isolate external electromagnetic wave interference, protect the normal operation of indoor equipment, or block the spread of indoor electromagnetic radiation to the outside world and prevent the leakage of electronic communication information.

[0003] Existing electromagnetic shielding doors are mainly divided into flat opening type and push-pull type. Among them, most push-pull shielding doors use ground groove shielding, and there is no threshold problem. However, the blade and beryllium copper reed in the pulling direction of conventional push-pull shielding doors are always in contact, and the pushing and pulling direction is often perpendicular to the designed deformation direction of the beryllium copper reed, resulting in greater wear of the beryllium copper reed beyond its shielding function; in addition, since the door leaf and door frame of conventional push-pull shielding doors are close to each other, the replacement of the beryllium copper reed is relatively troublesome.

[0039] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Embodiment 1:

[0041] Please refer to Figures 1 to 4 This embodiment provides a push-pull type threshold-free electric shielding door, which mainly includes a double-layer door body 1, a push-pull guide rail 2, a supporting guide device 3 and a moving trolley 4.

[0042] The double-layer door body 1 adopts a double-layer structure, including a main door body 11 and a movable shielding body 12 which can translate relative to each other. The main door body 12 is provided with a driving mechanism 10 for driving the movable shielding body 12 to translate in a direction perpendicular to the main door body 11 .

[0043] Specifically, the main door body 11 adopts a frame structure to reduce weight. The movable shielding body 12 is a structure that realizes shielding with the door frame 13, adopts a fully sealed panel, and the movable shielding body 12 and the door frame 13 are respectively equipped with matching inserts and beryllium copper reeds (traditional shielding structure, not shown in the figure).

[0044] In order to realize the relative translation of the main door body 11 and the movable shielding body 12, as Figure 2 and Figure 4 As shown, the driving mechanism 10 includes a driving motor 101 and a plurality of lifts 102 arranged on the main door body 11. The driving motor 101 and the lifts 102 are connected via a connecting rod mechanism 103. The output end of the lift 102 is arranged perpendicular to the main door body 11 and connected to the movable shielding body 12. It is worth mentioning that the driving mechanism 10 is preferably a four-linkage lift system, and the input adopts a hand-light dual-use input mode.

[0045] Under the action of the driving motor 101 and the connecting rod mechanism 103, the output end of the elevator 102 can move along Figure 4 The movable shielding body 11 can be extended and contracted in the left and right directions, thereby realizing the translation of the movable shielding body 11 relative to the main door body 11 / door frame 13, and realizing the fitting / separation of the movable shielding body 11 and the door frame 13. The translation direction is perpendicular to the main door body 11 / door frame 13, which can minimize the wear between the insert and the beryllium copper spring.

[0046] The push-pull guide rail 2 is arranged above the double-layer door body 1; wherein the top of the main door body 11 is slidably matched with the push-pull guide rail 2 via a roller mechanism 5, thereby realizing the translation of the double-layer door body 1 in a direction parallel to the door frame 13.

[0047] As Figure 3 shown, in the closed door state, the double-layer door body 1 is translated to the directly front of the door frame 13, thereby shielding the door frame 13.

[0048] As Figure 4 shown, in the open door state, the double-layer door body 1 is translated to the side of the door frame 13, thereby exposing the door frame 13.

[0049] Combined with the two-stage translation method in which the movable shielding body 11 translates perpendicular to the main door body 11 / door frame 13 and the double-layer door body 1 translates parallel to the door frame 13, during the process of opening and closing the door, the wear between the plug and the beryllium copper reed in the traditional electromagnetic shielding mechanism can be greatly avoided.

[0050] In this embodiment, in order to realize the translation of the double-layer door body 1 parallel to the door frame 13, as Figure 1 and Figure 5 shown, a rack 111 parallel to the push-pull guide rail 1 is installed on the main door body 1. In addition, a push-pull motor 112 is further included. A gear (not shown in the figure) is provided on the output shaft of the push-pull motor 112. The gear meshes with the rack 111. Under the operation of the push-pull motor 112, the rack and the double-layer door body 1 are driven to translate along the direction parallel to the door frame 13.

[0051] In order to realize the installation of the push-pull guide rail 2, a plurality of support beams 21 are evenly spaced on the push-pull guide rail 2. As Figure 6 shown, the support beam 21 is bolted to the push-pull guide rail 2.

[0052] As Figure 6 and Figure 7 shown, the roller mechanism 5 includes a U-shaped bracket 51. The bottom of the U-shaped bracket 51 is fixedly connected to the main door body 11. On both sides of the top of the U-shaped bracket 51, rollers 52 hanging on the push-pull guide rail 2 are symmetrically arranged. The number of rollers 52 is preferably 4, and they are distributed in two groups on both sides of the U-shaped bracket 51.

[0053] The support and guiding device 3 is arranged parallel to the push-pull guide rail 2 and is located below the main door body 11. A guide rod that is slidably matched with the support and guiding device 3 is arranged at the bottom of the main door body 11. The support and guiding device 3 plays a role in supporting and guiding the double-layer door body 1.

[0054] Preferably, the support and guiding device 3 adopts a guide rail, and rollers that fit with the support and guiding device 3 are also arranged at the bottom of the guide rod.

[0055] Embodiment 2:

[0056] In the solution of the first embodiment, since the bottom of the door frame 13 has a certain height, a threshold is formed. In order to facilitate the passage of vehicles, the second embodiment sinks the door frame 13 to a certain height so that the upper edge of the bottom side of the door frame 13 is flush with the ground. Figure 10 As shown, in order to install the support guide device 3 in Example 1 and the lower edge of the double-layer door body 1, a door groove 6 needs to be formed on the ground, and the door groove 6 will also hinder the passage of vehicles and the transportation of large equipment.

[0057] Based on this, the present embodiment adds a mobile car 4, such as Figure 1 and Figure 9 As shown, the moving trolley 4 is connected to the bottom of the main door body 11. In order to eliminate stress, the moving trolley 4 and the main door body 11 are preferably connected in an articulated manner. The moving trolley can slide along the supporting guide device 3 together with the main door body 11. Figure 3 As shown, in the door open state, the mobile trolley 4 moves into the door slot on the front side of the door frame 13, thereby filling the door slot to facilitate the passage of vehicles and the transportation of large equipment.

[0058] Specifically, Figure 8 and Figure 10 As shown, the mobile vehicle 4 includes a vehicle body 41 and a guide wheel 42 disposed at the bottom of the vehicle body 41 , and the guide wheel 42 is slidably / rollingly matched with the supporting guide device 3 .

[0059] The door slot 6 includes a running slot 62 and a guide slot 61 which are arranged from top to bottom. The width of the running slot 52 is greater than that of the guide slot 51 , thereby forming a substantially T-shaped door slot 6 .

[0060] The support guide device 3 and the guide wheel 42 are located in the guide groove 61 ; the vehicle body 41 is also provided with a running wheel 42 , and the running wheel 42 is in contact with the bottom of the running groove 62 .

[0061] like Figure 10 As shown in 11, in order to reduce the pressure between the moving trolley 4 and the supporting guide device 3 when unloaded, thereby reducing friction, it also includes an outer shell 431 and an inner sliding block 432 that are mutually nested in the vertical direction, the outer shell 431 is fixed on the vehicle body 41, and the running wheel 43 is installed on the inner sliding block 432; a disc spring 433 is arranged between the outer shell 431 and the inner sliding block 432.

[0062] In the no-load state (i.e., no-load), the disc spring 433 applies upward pressure to the outer shell 431 and the vehicle body 41, lifting the moving vehicle 4 so that the top of the vehicle body 41 is higher than the ground. At this time, the pressure between the supporting guide device 3 and the guide wheel 42 becomes smaller or even the two are not in contact, so that the sliding friction also decreases.

[0063] Under the load state (i.e., when the vehicle or large equipment presses on the moving trolley during travel), the disc spring 433 compresses, and the vehicle body 41 sinks accordingly until it is level with the ground. At this time, the guide wheels 42 and the walking wheels 43 jointly bear the weight of the vehicle or large equipment, and the walking wheels 43 will not be damaged due to excessive pressure.

[0064] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to embrace all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
