Description

Technical Field

[0001] The utility model relates to the technical field of shielding doors, in particular to an electromagnetic shielding door with expandable shielding effectiveness. Background Art

[0002] The gap leakage of the shielding room determines the shielding effectiveness. The shielding door is the most critical component to ensure that the overall performance of the shielding system is not degraded. It is also the only part of the system that needs to move frequently. It is to solve the leakage problem of the movable gap. Its performance greatly determines the electromagnetic shielding effectiveness of the shielding room.

[0003] According to the requirements of shielding technical indicators, the existing swing electromagnetic shielding doors on the market are divided into several structural types: single-pole double-spring, double-pole three-spring and double-pole four-spring. Usually, the door is locked and opened by a manual door opening mechanism.

[0004] The existing flat-hinged electromagnetic shielding doors can only achieve the shielding efficiency of a certain frequency band. If the shielding efficiency of a certain frequency band needs to be increased, the existing flat-hinged electromagnetic shielding doors need to be re-processed and manufactured, which is extremely cumbersome, time-consuming and expensive. Utility Model Content

[0005] The purpose of the utility model is to provide an electromagnetic shielding door with expandable shielding effectiveness, so as to solve the problem proposed in the above-mentioned background technology that it is not easy to achieve the shielding effectiveness of a certain frequency band, and the existing swing electromagnetic shielding door needs to be reprocessed and manufactured if the shielding effectiveness of a certain frequency band needs to be increased.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An electromagnetic shielding door with expandable shielding effectiveness comprises a door frame 1, a door leaf 2, a knife-type spring 3, a manual door opening mechanism 4, a cylinder 5, a handle 6, a mechanical / electronic access control 7, a travel switch 8, a fully automatic door machine 9 and a hinge 10, wherein 34 turns of the knife-type spring are mounted on the door frame 1, and 1 turn is mounted on the door leaf 2, the door frame 1 and the door leaf 2 are fixed by the hinge 10, three bolts on the hinge 10 are fixed on the door frame 1, and 8 bolts are fixed on the door leaf 2;

[0008] The blade-type reed 3 includes a first reed 301 , a second reed 302 , a third reed 303 , a fourth reed 304 and a fifth reed 305 . The first reed 301 , the second reed 302 , the fourth reed 304 and the fifth reed 305 are installed on the door frame 1 , and the third reed 303 is installed on the door leaf 2 .

[0009] The fourth reed 304 and the fifth reed 305 are sleeved on the reed base plate of the door frame 1, the first reed 301 and the second reed 302 are fixed to the door frame 1 by bolts, and the third reed 303 is fixed to the door leaf 2 by bolts.

[0010] The fourth reed 304 and the fifth reed 305 are detachably mounted on the reed base plate of the door frame 1 .

[0011] The opening angle of the fully automatic door machine 9 is 0° to 100°, the door opening and closing speed is 3 seconds to 7 seconds, and the holding time is 0.5 seconds to 30 seconds.

[0012] After the fully automatic door machine 9 is fully closed, a switch is formed to connect the start valve, and the cylinder 5 is actuated to drive the locking device to achieve a shielded connection between the door leaf 2 and the door frame 1.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model can change the number of reeds according to the shielding efficiency required by the shielding door. When the shielding requirement is low, the reeds are removed from the reed base plate. When the shielding requirement is high, the reeds are directly mounted on the reed base plate for use. The shielding door provided by the utility model uses three-circle reeds for fixed use and two-circle reeds for detachable use. When in use, it can be assembled by itself according to the shielding efficiency requirements, thereby increasing the usage scenarios. BRIEF DESCRIPTION OF THE DRAWINGS
