Technical Field

[0001] The utility model relates to the technical field of shielding covers, in particular to a split shielding cover. Background Art

[0002] The function of the shielding cover is to isolate the inside of the electronic device from the external environment, thereby preventing external electromagnetic waves, rays, noise and other interference from affecting the normal operation of the equipment. At the same time, the shielding cover can also prevent the equipment from radiating and interfering with other equipment or the environment.

[0003] Prior art, such as publication number: CN220457810U, discloses a split shielding cover, including a first shielding cover, a second shielding cover is arranged on the right side of the first shielding cover, a connecting mechanism is arranged between the first shielding cover and the second shielding cover, and a blocking mechanism is arranged on the outer walls of the first shielding cover and the second shielding cover. The split shielding cover blocking mechanism can form an effective barrier structure at the connection point, thereby realizing effective shielding of interference such as electromagnetic waves.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: at the connection points of the split shielding, an effective shielding cover structure is formed by adding a blocking mechanism, and it is equivalent to forming a shielding cover for shielding by connecting multiple blocking mechanisms together. During the installation process, it is necessary to repeatedly install the blocking mechanism, which is cumbersome and labor-intensive. At the same time, when a node of the split shielding cover needs to be rotated, the blocking mechanism at the corresponding node needs to be detached first before rotation, which is inconvenient to use.

[0005] In view of the above-mentioned existing split-type shielding, an effective shielding cover structure is formed by adding a blocking mechanism at the connection point, and it is equivalent to forming a shielding cover for shielding by connecting multiple blocking mechanisms together. During the installation process, it is necessary to repeatedly install the blocking mechanism, which is relatively cumbersome and labor-intensive. At the same time, when a node of the split-type shielding cover needs to be rotated, the blocking mechanism at the corresponding node needs to be detached first before rotation can be performed, which is inconvenient to use. Therefore, the present utility model is proposed.

[0006] Therefore, the utility model aims to provide a split shielding cover, which aims to connect two split shielding covers together by using whole-plate clamping, and can quickly realize the clamping of the two split shielding covers.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions: a split shielding cover, comprising a plurality of split shielding covers, the plurality of split shielding covers form a plane, and two adjacent split shielding covers are in a detachable connection state, and the two connected split shielding covers can be rotated;

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-5 , which is the first embodiment of the utility model, provides a split shielding cover, which includes a plurality of split shielding covers 1, wherein the plurality of split shielding covers 1 form a plane, and two adjacent split shielding covers 1 are in a detachable connection state, and the two connected split shielding covers 1 can be rotated;

[0031] The split shielding cover 1 includes a basic shielding plate 11, a connecting cavity 12 is provided on one side of the basic shielding plate 11, and an installation cavity 18 is provided on the other side of the basic shielding plate 11. A clamping shielding plate 17 clamped with the connecting cavity 12 is provided inside the installation cavity 18. When the two split shielding covers 1 are spliced, the clamping shielding plate 17 is already located inside the connecting cavity 12, and there is no need to install a shielding plate after the two split shielding covers 1 are fixed. At the same time, a whole clamping shielding plate 17 is used for blocking, which simplifies the assembly and disassembly process and is more convenient for installation and use.

[0032] A connecting block 2 is installed by bolts at the upper and lower sides of the front side of the basic shielding plate 11 close to the connecting cavity 12, and a connecting block 2 3 is installed by bolts at the upper and lower sides of the front side of the basic shielding plate 11 close to the mounting cavity 18. A rotating bar 22 is rotatably installed on the connecting block 2, and the rotating bar 22 and the connecting block 2 3 are detachably connected.

[0033] Two rotating frames 21 are welded on the connecting block 1 2 , a rotating shaft is rotatably installed between the opposite surfaces of the two rotating frames 21 , and a rotating bar 22 is sleeved on the rotating shaft.

[0034] A bolt through hole 23 is provided at one end of the connecting block 1 2 away from the rotating frame 21, and a hexagon socket bolt 24 is arranged inside the bolt through hole 23. A connecting threaded hole 31 threadedly connected to the hexagon socket bolt 24 is provided in the middle of the connecting block 2 3 near the rotating bar 22.

[0035] Five sliding holes 171 are opened near the basic shielding plate 11 of the snap-fit ​​shielding plate 17, and a T-shaped rod 110 is slidably installed inside the sliding hole 171, and the end of the T-shaped rod 110 away from the snap-fit ​​shielding plate 17 is welded to the inside of the installation cavity 18, and a spring 111 is sleeved on the rod part of the T-shaped rod 110. When two adjacent basic shielding plates 11 are in contact with each other, the snap-fit ​​shielding plate 17 is located inside the connecting cavity 12 and is subjected to force, so that the snap-fit ​​shielding plate 17 moves toward the direction of the T-shaped rod 110, and the snap-fit ​​shielding plate 17 compresses the spring 111. Under the elastic action of the spring 111, the snap-fit ​​shielding plate 17 is tightly in contact with the inner cavity of the connecting cavity 12.

[0036] When it is necessary to disassemble a split shielding cover 1, the corresponding hexagon socket bolt 24 is disassembled to disengage it from the threaded connection with the connecting threaded hole 31, so that the split shielding cover 1 to be disassembled is in a state of no bolt fixation, and then, the U-shaped frame 16 drives the snap-fitting shielding plate 17 to move in the direction of the connecting block 2, so that the snap-fitting shielding plate 17 compresses the spring 111 and disengages from the inside of the connecting cavity 12. Similarly, the snap-fitting shielding plate 17 on the split shielding cover 1 on its right side is also disengaged from the inside of the connecting cavity 12 on the split shielding cover 1 to be disassembled. At this time, the split shielding cover 1 can be disassembled.

[0037] During use, when two split shielding covers 1 are connected, the clip-on shielding plate 17 on one side enters the interior of the connecting cavity 12 on the other side, and makes the opposite surfaces of the two connected basic shielding plates 11 touch each other. At this time, the hexagon socket bolt 24 is screwed into the interior of the connecting threaded hole 31 to fix the connecting block 1 2 and the connecting block 2 3 together, thereby fixing the two connected split shielding covers 1. Similarly, other split shielding covers 1 can be installed in a splicing manner, and an appropriate number of split shielding covers 1 are selected according to the length of the required shielding area for splicing. The joints of the two split shielding covers 1 are blocked and shielded by the clip-on shielding plate 17.

[0038] Example 2

[0039] Reference Figure 1-5 , which is the second embodiment of the utility model, and this embodiment is different from the first embodiment in that:

[0040] A U-shaped frame 16 is welded to the top of the clamping shielding plate 17 , and a sliding cavity 15 for the vertical pipe end of the U-shaped frame 16 to pass through is opened on the front side of the basic shielding plate 11 .

[0041] The two vertical pipe ends of the U-shaped frame 16 are both sleeved with fixed connecting blocks 19, the top of the fixed connecting block 19 is provided with a bolt through hole 191, and a locking bolt is arranged inside the bolt through hole 191. The front side of the basic shielding plate 11 and the side close to the sliding cavity 15 are provided with two locking threaded holes 14 threadedly connected with the locking bolts. The locking bolts are passed through the bolt through holes 191 and threadedly connected with the locking threaded holes 14 to fix the clamping shielding plate 17 inside the installation cavity 18 without protrusions. There is no need to hold the U-shaped frame 16 and move it toward the connecting block 2 all the time, and the clamping shielding plate 17 can be kept stored in the installation cavity 18 for a long time.

[0042] When the basic shielding plate 11 needs to be rotated, first contact the threaded connection between the connecting block 1 2 and the connecting block 2 3, and retract the snap-on shielding plate 17 on the basic shielding plate 11 that needs to be rotated into the interior of the installation cavity 18. At the same time, retract the snap-on shielding plate 17 on the adjacent right side split shielding cover 1 from the interior of the connecting cavity 12, and then, under the rotating installation action of the rotating bar 22, the basic shielding plate 11 is rotated. Similarly, one split shielding cover 1 can be selected for rotation, or multiple split shielding covers 1 can be selected to be connected together for rotation.

[0043] A row of mounting holes 13 are provided at the upper and lower positions of the front surface of the basic shielding plate 11 , and four corners of the basic shielding plate 11 are provided with obtuse angles.

[0044] During use, when the snap-on shielding plate 17 is completely inserted into the interior of the installation cavity 18, the bolt through hole 191 and the locking threaded hole 14 are aligned, and the locking bolt is passed through the bolt through hole 191 and threadedly connected with the locking threaded hole 14 to fix the snap-on shielding plate 17 inside the installation cavity 18 without protrusion.

[0045] The remaining structures are the same as those of Example 1.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
