Abstract
The utility model provides a shielding door with a double structure, which comprises a middle cavity vertically penetrating through a shielding body, wherein two ends of the middle cavity are arranged in an open manner, and two ends of the middle cavity are respectively provided with a shielding door; the length of middle chamber is greater than the thickness of shield, and two shield doors are independently opened and close. The utility model can not damage the whole shielding effect of the shielding body in the process of personnel entering and exiting.
Description
Technical Field
The utility model belongs to the technical field of electromagnetic shielding, and particularly relates to a shielding door with a double structure.
Background
The electromagnetic shielding chamber is an important content in the field of electromagnetic compatibility (EMC), namely a steel plate house, and the cold-rolled steel plate is a main shielding material of the electromagnetic shielding chamber. The electromagnetic sealing device comprises six-sided shells, doors, windows and other common house elements, only requires strict electromagnetic sealing performance, and correspondingly shields all inlet and outlet pipelines so as to block electromagnetic radiation from entering and exiting.
Chinese patent CN208534362U discloses a single-blade single-groove steel plate screen door, on one hand, a single shielding blade is buckled in a single shielding-blade groove, so that the sealing performance of the screen door is better; on the other hand, when the shielding door is closed, the conductive cotton is convenient to form a conductive loop, and the electromagnetic wave can be shielded more effectively. However, the conventional shield door can damage the shield of the shield body when being opened and closed.
SUMMERY OF THE UTILITY MODEL
In order to solve the above problems, the present invention provides a double-structure shield door, which comprises the following specific schemes:
the shielding door comprises a middle cavity vertically penetrating through a shielding body, wherein two ends of the middle cavity are arranged in an open mode, and two ends of the middle cavity are respectively provided with a shielding door; the length of middle chamber is greater than the thickness of shield, two the shield door is independently opened and close.
Furthermore, two shielding doors are respectively provided with a locking device, each locking device comprises a locking groove arranged on the inner wall of the middle cavity, and a lock tongue of each shielding door can extend into the locking groove; the locking groove is internally provided with an electric pin, the working direction of the electric pin is perpendicular to that of the lock tongue, and the lock tongue is provided with a locking hole matched with the electric pin.
Furthermore, the locking devices of the two shielding doors are connected with a control circuit, and the control circuit comprises a single chip microcomputer; when one locking device is in the unlocking state, the single chip microcomputer is used for controlling the other locking device to keep the locking state.
Furthermore, the opening direction of the shielding door is the direction far away from the middle cavity.
The utility model has the beneficial effects that: according to the shielding door with the double structure, personnel can not damage the whole shielding effect of the shielding body when entering and exiting.

Detailed Description
The utility model is further described with reference to the following figures and examples, which are provided only for illustrating the utility model and are not intended to limit the scope of the utility model.
With reference to fig. 1 and 2, a double-structure shielded gate includes a middle cavity 2 vertically passing through a shield 1, two ends of the middle cavity 2 are opened, and two ends of the middle cavity 2 are respectively provided with a shielded gate 3; the length of middle chamber 2 is greater than the thickness of shield 1, and two shielding doors 3 open and close independently.
The two shielding doors 3 are respectively provided with a locking device, as shown in fig. 3, each locking device comprises a locking groove 4 arranged on the inner wall of the middle cavity 2, and a lock tongue 5 of each shielding door 3 can extend into the locking groove 4; an electric pin 6 is arranged in the locking groove 4, the working direction of the electric pin 6 is perpendicular to that of the lock tongue 5, and a locking hole matched with the electric pin 5 is formed in the lock tongue 5.
The locking devices of the two shielding doors 3 are both connected with a control circuit, and the control circuit comprises a single chip microcomputer; when one of the locking devices is in the unlocking state, the single chip microcomputer is used for controlling the other locking device to keep the locking state. Therefore, when workers enter and exit the shielding body, at least one shielding door is in a closed state, and the overall shielding effect of the shielding body is ensured.
The opening direction of the shielding door 3 is the direction far away from the middle cavity 2, so that the shielding door can conveniently enter and exit (the shielding door can also adopt a rolling door mode, and the problem of the opening direction is not considered).
Therefore, the utility model is not limited to the specific embodiments and examples, but rather, all equivalent variations and modifications are within the scope of the utility model as defined in the claims and the specification.
