Technical Field

[0001] The invention belongs to the technical field of electromagnetic shielding of shielding cabinets, and in particular relates to a double-slot shielding mechanism for a double-door shielding cabinet. Background Art

[0002] Shielding cabinets are file cabinets with shielding functions. Existing shielding cabinets are generally door-opening structures. In order to ensure their shielding functions, shielding slots and shielding blades are correspondingly arranged between the inner wall of the cabinet door and the cabinet body. Single-door cabinets have a large opening and closing range, which is very inconvenient to use. Therefore, double-door shielding cabinets have appeared in the market. However, when the traditional shielding slots and shielding blades are applied to double-door shielding cabinets, the two are not easy to match, especially the matching part of the two cabinet doors, which makes it difficult to open and close the cabinet door, and the shielding slots and shielding blades are severely worn, shortening their service life and directly affecting the shielding performance of the entire shielding cabinet.

[0003] In addition, the existing shielding trough needs to be equipped with a conductive lining during installation to ensure the conductivity between the shielding trough and the shielding cabinet, which directly increases the complexity of the shielding trough installation. Summary of the invention

[0004] The purpose of the present invention is to provide a double-slot shielding mechanism for a double-door shielding cabinet to solve the problem of poor shielding performance.

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] Example 1

[0031] like Figure 1-3 As shown, a double-slot shielding mechanism for a double-door shielding cabinet includes a shielding slot 1 and a shielding blade 2. The shielding slot 1 includes a slot Ⅰ11 and a slot Ⅱ12. Reeds 3 arranged opposite to each other are installed on the side walls of the slot Ⅰ11. A reed 3 is installed on the side wall of the slot Ⅱ12 close to the slot Ⅰ11. A connecting plate 4 is installed on the back of the shielding slot 1. An assembly slot 5 is formed between the connecting plate 4 and the shielding slot 1. The shielding blade 2 is a double-blade structure matched with the shielding slot 1, and the two blades are correspondingly inserted into the slot Ⅰ11 and the slot Ⅱ12. The side of the shielding blade 2 fits with the corresponding reed 3.

[0032] The shielding slot 1 disclosed in this embodiment is suitable for the cabinet body 61 of the shielding cabinet 6, and the shielding blade 2 matched with the shielding slot 1 is installed on the inner wall of the cabinet door.

[0033] In order to form a double-groove structure, the shielding groove 1 includes an inner plate 13, a middle plate 14 and two side plates 15 that are integrally arranged. The middle plate 14 and the side plates 15 are arranged on the front side of the inner plate 13 and are arranged perpendicular to the inner plate 13. The two side plates 15 are respectively located on both sides of the middle plate 14 and form a groove.

[0034] The setting of the connecting plate 4 can increase the stability of the connection between the shielding slot 1 and the shielding cabinet 6. In order to facilitate the cooperation with the assembly plate 62 on the shielding cabinet 6 for installing the shielding slot 1, the inner plate 13 is arranged parallel to the connecting plate 4, and the back of the inner plate 13 is provided with an L-shaped extension portion 16 integrated therewith. The connecting plate 4 is connected to the extension portion 16 through an S-shaped card interface 17.

[0035] During installation, the assembly plate 62 is placed against the inner plate 13, and the edge of the assembly plate 62 is inserted into the inner side of the extension portion 16, and then the connecting plate 4 is fixed to the side of the assembly plate 62 facing away from the inner plate 13, and then the assembly plate 62 can be installed in the assembly groove 5 using screws.

[0036] The S-shaped card interface 17 can increase the stability of the cooperation between the extension portion 16 and the connecting plate 4 .

[0037] In order to facilitate the installation of the spring leaf 3, a U-shaped groove 18 is provided on the outer end surface of the middle plate 14, and mounting grooves 19 are provided on the inner walls on both sides of the U-shaped groove 18 and the outer wall of the side plate 15 corresponding to the groove Ⅰ11, and the upper end of the spring leaf 3 is fixed in the mounting groove 19 accordingly.

[0038] Specifically, the upper edge and the lower edge of the spring sheet 3 are an integrated structure and are divided in the middle, so as to increase the elasticity of the spring sheet 3 and improve the shielding effect when it cooperates with the shielding blade 2.

[0039] The reed 3 includes a reed body 31 and a U-shaped mounting portion 32 integrally provided with the reed body 31 and located above the reed body 31. The reed body 31 is an arc-shaped body that bends toward the center of the slot where it is located, so that the reed body 31 can be compressed when the shielding blade 2 is inserted into the slot, thereby increasing the contact area between the reed body 31 and the shielding blade 2, thereby improving the shielding effect.

[0040] The opening of the U-shaped mounting portion 32 is opposite to the direction of the slot. Taking the spring leaf 3 installed on the middle plate 14 as an example, the U-shaped mounting portion 32 covers the side wall of the U-shaped slot 18, and a card 33 inclined toward the inside of the U-shaped mounting portion 32 is provided on its outer side wall. The card 33 is inserted into the mounting slot 19, thereby fixing the spring leaf 3 on the middle plate 14.

[0041] The reed 3 can be made of beryllium copper.

[0042] In order to facilitate the mating or separation of the shielding blade 2 and the shielding slot 1 , the width of the slot II 12 is smaller than the width of the slot I 11 , and the height of the side plate 15 constituting the slot II 12 is smaller than the height of the middle plate 14 and the other side plate 15 .

[0043] The side plate 15 corresponding to the slot II 12 is an outer plate, that is, when the shielding blade 2 is separated from the shielding slot 1, the shielding blade 2 rotates toward the slot I 11. Therefore, the reed 3 is only installed on the inner wall of the slot II 12 to prevent the reed 3 from blocking the movement of the shielding blade 2.

[0044] The small width of the slot II 12 can reduce the space occupied by the entire shielding slot 1. In this embodiment, reducing the height of the side plate 15 corresponding to the slot II 12 can prevent the side plate 15 from blocking the matching of the shielding blade 2 and the shielding slot 1.

[0045] In this embodiment, when the shielding blade 2 is matched with or separated from the shielding slot 1, the side plate 15 corresponding to the slot II 12 is the outer side plate 15.

[0046] In order to cooperate with the mounting plate 62 on the shielding cabinet 6 , the extension portion 16 is located at the back of the slot II 12 .

[0047] In order to stably connect the shielding slot 1 and the connecting plate 4 to the assembly plate 62 , a mounting through hole 110 is provided on the inner plate 13 corresponding to the slot Ⅰ11 , and a connecting hole 41 corresponding to the mounting through hole 110 is provided on the connecting plate 4 .

[0048] A screw is installed in the mounting through hole 110, and the screw is installed from the slot Ⅰ11, and then passes through the mounting through hole 110, the assembly plate 62 on the shielding cabinet 6 and the connecting hole 41 in sequence, thereby firmly installing the shielding slot 1, the assembly plate 62 and the connecting plate 4 together.

[0049] Compared with the existing shielding slot structure with a conductive liner, the density of screws installed in this embodiment is much smaller than that of the original shielding slot structure, and the installation is faster and more convenient.

[0050] In this embodiment, the shielding slots 1 are installed on the cabinet body 61 of the shielding cabinet 6, and the shielding slots 1 on the left and right sides of the cabinet body 61 are symmetrically arranged. Taking the right cabinet door 63 as an example, the slot I 11 is close to the outside of the cabinet body 61, and the slot II 12 is close to the inside of the cabinet body 61. The shielding blade 2 is installed on the inner wall of the cabinet door. The right cabinet door 63 is hinged to the cabinet body 61. When the right cabinet door 63 is rotated to close, the shielding blade 2 is matched in the shielding slot 1. When the right cabinet door 63 is opened, the shielding blade 2 is drawn out of the shielding slot 1.

[0051] The shielding slots 1 located on the upper and lower sides of the cabinet body 61 can be arranged symmetrically or in the same direction. Both methods will not affect the cooperation between the shielding blades 2 and the shielding slots 1 when the cabinet door is opened or closed.

[0052] Example 2

[0053] like Figure 4-5 As shown, based on Example 1, the double-door shielding cabinet 6 disclosed in this embodiment uses a double-slot shielding mechanism, and its structure is roughly the same as the structure disclosed in Example 1, except that:

[0054] The width of the notch Ⅰ11 is equal to the width of the notch Ⅱ12.

[0055] Since the two cabinet doors are relatively opened, the side plate 15 corresponding to the notch II 12 also serves as an outer plate, that is, when the shielding blade 2 is separated from the shielding slot 1, it rotates toward the notch I 11.

[0056] In this embodiment, the widths of the two notches are the same, which can ensure smooth cooperation between the shielding blade 2 and the shielding slot 1.

[0057] In order to cooperate with the mounting plate 62 of the left cabinet door 64, the extension portion 16 is located at the back of the groove I11.

[0058] Since the slot I11 is opposite to the extension portion 16 , in order to avoid the S-shaped card interface 17 and facilitate the fixation of the connecting plate 4 and the shielding slot 1 , a mounting through hole 110 is provided on the inner plate 13 corresponding to the slot II12 , and a connecting hole 41 corresponding to the mounting through hole 110 is provided on the connecting plate 4 .

[0059] The shielding slot 1 structure disclosed in this embodiment is suitable for shielding cooperation between two cabinet doors.

[0060] Specifically, there is an assembly plate 62 on the right edge of the left cabinet door 64, and the shielding slot 1 is installed on the assembly plate 62 in the same way as in Example 1, with its slot facing outward, slot I11 located on the right, and slot II12 located on the left, and a shielding blade 2 that cooperates with the shielding slot 1 is installed on the left inner wall edge of the right cabinet door 63.

[0061] The shielding slot 1 disclosed in this embodiment is also applicable to the upper and lower sides of the cabinet 61, and can also be installed in a symmetrical or same-direction manner.

[0062] In the double-slot shielding mechanism disclosed in the present invention, the slot II 12 can be equipped with a spring sheet 3 on one side, or it can be the same as the slot I 11, with spring sheets 3 installed on both sides, thereby forming a shielding slot 1 with a double-slot three-spring or double-slot four-spring structure, which has good shielding performance and is not only suitable for shielding cabinet structures, but also for smaller cabinet structures.

[0063] The shielding slot 1 in the present invention is formed by metal stretching in one step, with high processing precision, so that the shielding performance is guaranteed. Due to the cooperation between the shielding slot 1 and the connecting plate 4, a good connection with the assembly plate on the shielding cabinet 6 can be achieved, thereby ensuring the conductive performance between the shielding slot 1 and the shielding cabinet 6, without the need to install a conductive lining separately, and more convenient to use.

[0064] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
