Description

Technical Field

[0001] This utility model belongs to the field of shielding door technology, specifically an electric swing shielding door driven by a rotary motor. Background Technology

[0002] A shielded door is a door used to enclose and protect a specific area. It is designed to provide isolation, protection, or confidentiality. Shielded doors are usually made of durable materials, such as steel or other reinforced materials. These doors can provide effective protection against the entry of external objects, noise, or other environmental conditions.

[0003] When traditional swing shielded doors are closed, there are often gaps between the door frame and the door leaf in the inspection room. These gaps may allow noise or electromagnetic interference signals to escape from the inspection room, resulting in poor shielding performance. Utility Model Content

[0004] The purpose of this invention is to provide an electric swing shielding door driven by a rotary motor, so as to solve at least one aspect of the problems and defects mentioned in the background art.

[0005] An electric swing shielding door driven by a rotary motor is provided, including a door frame and a door leaf. The door leaf is hinged to the door frame via hinges. A dual-axis motor is provided on the upper part of the door frame. The output ends of the dual-axis motor are fixedly connected to the first compression rods. The first compression rods are rotatably connected to the first support base. The first support base is disposed on the door frame. A first elastic component is provided between the first compression rods and the door leaf. A first bevel gear is fixedly connected to the first compression rods. The first bevel gear meshes with a second bevel gear. A second compression rod is fixedly connected to the second bevel gear. The second compression rod is rotatably connected to the second support base. The second support base is disposed on one side of the door frame. The first elastic component is provided between the second compression rods and the door leaf.

[0006] A drive motor is provided at the bottom of the door leaf, and a third compression rod is fixedly connected to the output end of the drive motor. The third compression rod is rotatably connected to a third support base, and the third support base is fixedly connected to the bottom of the door leaf. A second elastic component is provided between the third compression rod and the door frame.

[0007] Furthermore, the first elastic component includes a first shielding spring, a first rectangular square tube, and a first elastic spring. One end of the first elastic spring is bolted to the door frame, and the end of the first elastic spring away from the door frame is connected to the first rectangular square tube. The first shielding spring is fixedly connected to the first rectangular square tube. The first shielding spring is disposed between the first compression rod and the door leaf, and the second shielding spring is disposed between the second compression rod and the door leaf.

[0008] Furthermore, the second elastic component includes a second shielding spring, a second rectangular tube, and a second elastic spring. One end of the second elastic spring is bolted to the door leaf, and the end of the second elastic spring away from the door leaf is connected to the second rectangular tube. The second shielding spring is fixedly connected to the second rectangular tube, and the second shielding spring is disposed between the second compression rod and the door frame.

[0009] Furthermore, the first shielding spring includes a deformable portion and a fixing portion.

[0010] Furthermore, the second shielding spring includes a deformable portion and a fixing portion.

[0011] Furthermore, the door leaf is also equipped with a handle and a door lock.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] After the door leaf and door frame are closed by rotating the hinges, the dual-axis motor drives the first compression rods on both sides to rotate. The rotation of the first compression rods compresses the first elastic component to shield the gap between the top of the door frame and the door leaf. In addition, the rotation of the first compression rods drives the first bevel gear to rotate, which in turn drives the second bevel gear to rotate, thereby driving the second compression rod to rotate. The rotation of the first compression rods compresses the first elastic component, shielding the gaps on both sides of the door frame and door leaf. The drive motor starts and drives the second compression rod to rotate at the bottom of the door leaf. During the rotation of the third compression rod, the second elastic component is compressed to the amount of compression that meets the shielding requirements, thus achieving shielding between the bottom of the door leaf and the door frame and avoiding the problem of poor shielding effect caused by gaps between the door frame and the door leaf in the inspection room.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] 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 claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention. Please refer to... Figure 1-4 As shown in the present invention, an electric swing shielding door driven by a rotary motor includes a door frame 1 and a door leaf 2. The door leaf 2 is hinged to the door frame 1 by a hinge. A dual-axis motor 3 is provided on the upper part of the door frame 1. The output ends of the dual-axis motor 3 are fixedly connected to the two sides of the output end of the dual-axis motor 3. The first compression rod 4 is rotatably connected to the first support seat 5. The first support seat 5 is provided on the door frame 1. A first elastic component 6 is provided between the first compression rod 4 and the door leaf 2.

[0022] A first bevel gear 41 is fixedly connected to the first compression rod 4. The first bevel gear 41 is meshed with a second bevel gear 42. A second compression rod 7 is fixedly connected to the second bevel gear 42. The second compression rod 7 is rotatably connected to a second support seat 8. The second support seat 8 is located on one side of the door frame 1. A first elastic component 6 is provided between the second compression rod 7 and the door leaf 2.

[0023] A drive motor 9 is provided at the bottom of the door leaf 2. The output end of the drive motor 9 is fixedly connected to a third compression rod 10. The third compression rod 10 is rotatably connected to a third support base 11. The third support base 11 is fixedly connected to the bottom of the door leaf 2. A second elastic component 12 is provided between the third compression rod 10 and the door frame 1.

[0024] After the door leaf 2 and door frame 1 close by rotating and closing via the hinges, the dual-axis motor 3 drives the first compression rods 4 on both sides to rotate. The rotation of the first compression rods 4 compresses the first elastic component 6 to shield the gap between the top of the door frame 1 and the door leaf 2. The rotation of the first compression rods 4 drives the first bevel gears 41 on both sides to rotate. The first bevel gears 41 drive the second bevel gear 42 to rotate, which in turn drives the second compression rod 7 fixedly connected to the second bevel gear 42 to rotate. The rotation of the second compression rod 7 compresses the first elastic component 6 to the amount of compression that meets the shielding requirements, thereby achieving shielding between the door frame 1 and the door leaf 2 on both sides. The drive motor 9 starts and drives the third compression rod 10 to rotate at the bottom of the door leaf 2. During the rotation of the second compression rod 7, the second elastic component 12 is squeezed and compressed to the amount that meets the shielding requirements, so as to achieve shielding between the bottom of the door leaf 2 and the door frame 1, ensuring that the door leaf 2 and the door frame 1 of the inspection room are connected as one unit to form an overall shield. The door leaf 2 of the shielded door is non-magnetic, which can prevent the electromagnetic signals generated in the inspection room from being transmitted out. The motor is outside the shielding layer to prevent noise and electromagnetic noise signals from being transmitted from the inspection room and affecting the electronic equipment outside the inspection room.

[0025] In one embodiment, see Figure 2 , Figure 3 and Figure 4 The first compression rod 4, the second compression rod 7, and the third compression rod 10 are all compression rods with a cam-shaped cross section. During the rotation of the first compression rod 4, the second compression rod 7, and the third compression rod 10, they use their cam-shaped cross sections to compress the first elastic component 6 and the second elastic component 12, respectively.

[0026] In one embodiment, see Figure 1 , Figure 2 as well as Figure 3 The first elastic component 6 includes a first shielding spring 63, a first rectangular tube 62, and a first elastic spring 61. One end of the first elastic spring 61 is bolted to the door frame 1, and the end of the first elastic spring 61 away from the door frame 1 is connected to the first rectangular tube 62. The first shielding spring 63 is fixedly connected to the first rectangular tube 62. The first shielding spring 63 is disposed between the first compression rod 4 and the door leaf 2 (to shield the gap between the top of the door frame 1 and the door leaf 2). The first shielding spring 63 is disposed between the second compression rod 7 and the door leaf 2 (to shield the gap between the two sides of the door frame 1 and the door leaf 2).

[0027] The first elastic spring 61 has a certain degree of deformation and extension, which can place the first shielding spring 63 of the first rectangular tube 62 between the first compression rod 4 and the door leaf 2. During the rotation of the first compression rod 4, the first shielding spring 63 is squeezed and compressed to the amount of compression that meets the shielding requirements.

[0028] In one embodiment, see Figure 1 as well as Figure 4 The second elastic component 12 includes a second shielding spring 123, a second rectangular tube 122, and a second elastic spring 121. One end of the second elastic spring 121 is bolted to the door leaf 2, and the end of the second elastic spring 121 away from the door leaf 2 is connected to the second rectangular tube 122. The second shielding spring 123 is fixedly connected to the second rectangular tube 122. The second shielding spring 123 is disposed between the second compression rod 7 and the door frame 1. The second elastic spring 121 has a certain degree of deformation and extension, which can place the second shielding spring 123 of the second rectangular tube 122 between the second compression rod 7 and the door frame 1. During the rotation of the second compression rod 7, the second shielding spring 123 is squeezed and compressed to the amount of compression that meets the shielding requirements.

[0029] In one embodiment, see Figure 2 , Figure 3 and Figure 4 Both the first shielding spring 63 and the second shielding spring 123 include a deformable part and a fixing part. The deformable part is used to fill the gap between the door frame 1 and the door leaf 2 by deforming after being squeezed. The deformable part of the first shielding spring 63 is used to fill the gap at the top of the door frame 1 and the door leaf 2 and the gaps on both sides of the door frame 1 and the door leaf 2 by squeezing during the rotation of the first compression rod 4 or the second compression rod 7. The deformable part of the second shielding spring 123 is used to fill the gap at the bottom of the door frame 1 and the door leaf 2 by squeezing during the rotation of the third compression rod 10. The fixing part is used to weld the first shielding spring 63 and the second shielding spring 123 onto the first rectangular square tube 62 and the second rectangular square tube 122, respectively.

[0030] In one embodiment, see Figure 1 and Figure 3 The door leaf 2 is also equipped with a handle 21 and a door lock 22. Turning the handle 21 and using the locking tongue in the door lock 22 can lock the door leaf 2 and the door frame 1. After locking, the dual-axis motor 3 starts to shield the top gap between the door frame 1 and the door leaf 2 and the gaps on both sides of the top gap between the door frame 1 and the door leaf 2, and the drive motor 9 starts to shield the bottom gap between the door frame 1 and the door leaf 2.

[0031] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
