[0002] A shielded protective shell is a component that is filled with shielding signals inside a protective shell. It is usually installed in areas where more signals occur. It is used to isolate and protect a certain area or certain objects, thereby preventing external signals from contacting the wires inside the object or area.

[0003] For example, a communication signal shielding box with Chinese patent publication number CN212910646U includes a shielding shell, a fixed card block, a shielding placement box, a shielding cover, a fixed connection airbag and an adaptive clamping assembly. The shielding shell is arranged as a hollow cavity with an upper end opening, the shielding cover is arranged at the upper end opening of the shielding shell, the fixed card blocks are symmetrically arranged at both ends of the bottom wall of the shielding shell, the shielding placement box is arranged on the bottom wall of the shielding shell and between the fixed card blocks, the fixed connection airbag is arranged at the upper end of the fixed card block, the fixed connection airbag is symmetrically arranged on both sides of the shielding placement box, the adaptive clamping assembly is arranged in the shielding placement box, the adaptive clamping assembly is symmetrically arranged, and a weighting layer is provided in the bottom wall of the shielding shell.

[0004] The signal shielding box in the above patent can only achieve the purpose of clamping objects when in use, while the existing protective shells are mostly in an integrated setting when in use, so that the outer size of the protective shell cannot be adjusted, resulting in the protective shell being unable to adapt to protective work of different lengths. Therefore, a device is needed to improve the above problem. Utility Model Content

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

[0013] When the device is in use, the first shielding enclosure and the second shielding enclosure are separately arranged so that the first shielding enclosure and the second shielding enclosure can be pulled in separate directions, thereby adjusting the protective lengths of the first shielding enclosure and the second shielding enclosure. At the same time, the first shielding enclosure can be linearly displaced inside the second shielding enclosure to prevent the first shielding enclosure and the second shielding enclosure from being skewed. Furthermore, a limiting rod can pass through the interior of the first top cover and the second top cover, so that the first shielding enclosure and the second shielding enclosure can be limited to a specified length for protective work.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 , the utility model provides an embodiment: a communication technology shielding protection shell, including a first matching device 2, the first matching device 2 is slidably inserted with a second matching device 3, the top of the first matching device 2 is fixedly installed with a positioning device 1, the positioning device 1 includes a synchronization rod 4, a support base frame 5, a reset spring 6, a limit rod 7 and a guide gasket 8, the limit rod 7 is slidably inserted in the inner center of the support base frame 5, the guide gasket 8 is fixedly installed on the outer ring of the limit rod 7, the reset spring 6 is fixedly installed between the guide gasket 8 and the support base frame 5, the synchronization rod 4 is fixedly installed between the two limit rods 7, the first matching device 2 includes a first top cover 9, a first shielding enclosure 10 and a guide groove 11, the first top cover 9 is fixedly installed on the top of the first shielding enclosure 10, and the guide groove 11 is symmetrically opened on the inner side of the first shielding enclosure 10.

[0021] The second matching device 3 includes an alignment hole 12, a guide slide key 13, a second shielding enclosure 14 and a second top cover 15. The alignment holes 12 are equidistantly arranged on the top of the second top cover 15. The second top cover 15 is fixedly mounted on the top of the second shielding enclosure 14. The guide slide key 13 is symmetrically fixedly mounted on both sides of the second shielding enclosure 14. The alignment hole 12 is vertically aligned with the limiting rod 7, so that the limiting rod 7 can be easily inserted into the interior of the alignment hole 12.

[0022] The guide sliding key 13 is slidably inserted in the guide groove 11, and the support base frame 5 is symmetrically fixedly installed on the top side end of the first top cover 9 to support the synchronization rod 4 to work.

[0023] Round holes are symmetrically provided at the top side ends of the first top cover 9 , so as to facilitate the limiting rod 7 to penetrate through the first top cover 9 and be inserted into the alignment hole 12 .

[0024] The bottom end of the first top cover 9 is flush with the top end of the second top cover 15 , thereby improving the tightness of the fit between the first top cover 9 and the second top cover 15 .

[0025] The outer surface of the second shielding enclosure 14 fits with the inner surface of the first shielding enclosure 10 to prevent excessive external dust from entering the second shielding enclosure 14 and the first shielding enclosure 10. The first top cover 9 and the second top cover 15 are filled with shielding materials to improve the overall shielding performance of the first shielding enclosure 10 and the second shielding enclosure 14.

[0026] Working principle: During use, when the first shielding enclosure 10 and the second shielding enclosure 14 need to adapt to the protection work of different length areas, the synchronization rod 4 can be pulled upward, so that the limiting plug rod 7 can be driven to move upward at the same time, until the limiting plug rod 7 is moved out from the alignment hole 12 and the inside of the first top cover 9, and then the second shielding enclosure 14 is pulled to the end away from the first shielding enclosure 10, so that the spacing between the first shielding enclosure 10 and the second shielding enclosure 14 can be adjusted, and while the second shielding enclosure 14 moves, the guide sliding key 13 slides inside the guide groove 11, so that the second shielding enclosure 14 can be supported to move in a straight line. Afterwards, when the second shielding enclosure 14 moves to the specified position, the alignment hole 12 can be driven to be vertically aligned with the circular hole on the top of the first top cover 9. At this time, the user releases the synchronization rod 4 again, and the elasticity of the reset spring 6 will drive the guide gasket 8 to move downward quickly, and the guide gasket 8 is fixedly installed on the limiting plug rod 7, so that the guide gasket 8 moves downward. At the same time as the movement, the limiting plug rod 7 can be driven to pass through the circular hole on the first top cover 9 again until the limiting plug rod 7 is inserted into the interior of the alignment hole 12, so that the first top cover 9 and the second top cover 15 can be limited and positioned to prevent the first shielding enclosure 10 and the second shielding enclosure 14 from sliding and displacing again, and the length adjustment work of the first shielding enclosure 10 and the second shielding enclosure 14 is completed. When the device is in use, several alignment holes 12 are set on the top of the second top cover 15, so that the limiting plug rod 7 can be inserted into the alignment holes 12 at different positions, so that the second shielding enclosure 14 and the first shielding enclosure 10 can be adjusted to the specified length for protection work, and the inner surfaces of the first top cover 9 and the first shielding enclosure 10 are respectively fitted with the outer surfaces of the second top cover 15 and the second shielding enclosure 14, so that the fitting tightness between the first shielding enclosure 10 and the second shielding enclosure 14 can be improved, and dust can be reduced from entering the interior of the first shielding enclosure 10 and the second shielding enclosure 14 to complete the work.
