The signal blocker will adjust the frequency of the electromagnetic waves it emits according to the signal frequency of the target device to achieve the best shielding effect.

[0003] The prior art has a patent number of CN215956400U, which discloses a signal blocker for an examination room. The signal blocker has the characteristics of stable installation. The sliding positioning block and the magnetic adsorption are arranged on the base fixed to the wall to ensure the stable installation of the blocker body. At the same time, the slide groove and the slider design are used to further fix the blocker to the base. The patent not only enhances the stability between the signal blocker and the wall, but also improves the safety during use, effectively preventing it from falling due to external force.

[0004] However, the patent realizes the fixation of the block by driving the threaded rod to rotate through the worm, which requires cumbersome rotation of the worm for multiple times, which greatly affects the installation and disassembly time and is inconvenient for fixation;

[0005] In addition, during installation and disassembly, the drive can only be performed by the rotation of the worm. If the worm and the bidirectional screw are damaged, they cannot be disassembled, and the flexibility is poor. Utility Model Content

A vertical rod 15 is fixedly connected to the bottom of the connecting rod 14, and a push rod 16 is fixedly connected to one side of the vertical rod 15. The bottom ends of the four disassembly rods 11 are fixedly connected to the top of the connecting rod 14. A mounting groove 17 is provided inside the mounting block 4. Through the arrangement of structures such as the locking block 8 and the clamping block 9, the mounting block 4 is moved toward the position of the fixed block 5, so that the locking block 8 is placed inside the mounting groove 17, and then fixed by the clamping block 9 and the locking block 8. Continue to press, and disassembly is achieved through the cooperation of the clamping block 9 and the sliding block 7, so as to realize the disassembly and assembly of the shielding device body 3. The structure is simple and the operation is convenient. There is no need to perform multiple screwing operations, thereby improving the installation efficiency.

[0030] like Figure 3-Figure 4 As shown, two slots are provided inside the mounting block 4, the slots are slidably connected to the clamping block 9, and a clamping spring 12 is fixedly connected between the clamping block 9 and the inner wall of the slot.

[0031] like Figure 3 As shown, two slide grooves are provided inside the mounting block 4, and a portion of the disassembly rod 11 is slidably connected inside the slide grooves. A return spring 13 is fixedly connected between the disassembly rod 11 and the inner wall of the slide grooves.

[0032] like Figure 3-Figure 6 As shown, a telescopic groove is provided inside the cross bar 25, and a portion of the pull rod 10 is slidably connected inside the telescopic groove.

[0033] like Figure 3 As shown, a circular groove is formed on the sliding block 7, and the straight rod 6 passes through the inside of the circular groove. The top of the sliding block 7 and the bottom of the fixed block 5 are fixedly connected with a driving spring 18.

[0034] like Figure 1-Figure 3 As shown, a groove is provided inside the mounting seat 2, and the connecting rod 14 is slidably connected inside the groove.

[0035] The specific implementation principle of this embodiment is as follows: take the shielding device body 3, drive the mounting block 4 on the mounting seat 2 to move toward the position of the fixed block 5 on the base 1, so that the locking block 8 is placed inside the mounting groove 17. During the movement, the curved surface of the card block 9 is squeezed, so that the card block 9 moves toward the inside of the card slot. When it is moved to the top of the locking block 8, the clamping spring 12 is no longer subjected to force, and the card block 9 is driven to reset. The card block 9 is clamped on the top of the locking block 8 to achieve clamping and fixing. The shielding device body 3 is installed again, so that the card block 9 is clamped on the sliding block 7, and the shielding device body 3 is pulled downward, that is, the mounting block 4 moves downward, and the card block 9 drives the slider to move downward synchronously.

[0036] Furthermore, when the card block 9 moves into the card slot, it drives the cross bar 25 to move. Due to the setting of the telescopic slot, the movement of the cross bar 25 will not drive the pull rod 10 to move, and will not be restricted by the disassembly rod 11. After the disassembly is completed, the driving spring 18 drives the sliding block 7 to reset for the next installation and use.

Through the arrangement of the disassembly rod 11, the positioning block 21 and other structures, if the friction between the card block 9 and the sliding block 7 is insufficient, the push rod 16 can be pushed to drive the disassembly rod 11 to realize the movement of the card block 9, and then it can be disassembled. At the same time, the positioning block 21 realizes the limited positioning of the push rod 16 to avoid accidental contact causing the card block 9 to move, and realize disassembly, thereby making the device more practical.

[0039] like Figure 1-Figure 5 As shown, a positioning groove is provided inside the mounting seat 2, a portion of the positioning block 21 is slidably connected inside the positioning groove, and a positioning spring 24 is fixedly connected between the positioning block 21 and the inner wall of the positioning groove.

[0040] The specific implementation principle of this embodiment is as follows: pull the fixing rod 23 to drive the positioning rod 22 to move, and the positioning rod 22 drives the positioning block 21 to move, and then the push rod 16 can be moved, and the positioning rod 22 is loosened, and the positioning spring 24 drives the positioning block 21 to reset, so as to fix the push rod 16. When the friction between the sliding block 7 and the block 9 is not enough to drive the sliding block 7 to move, push the push rod 16, and the push rod 16 drives the vertical rod 15 to realize the movement of the connecting rod 14. The connecting rod 14 drives the four disassembly rods 11 to move, so that the inclined surface 20 of the disassembly rod 11 squeezes the disassembly groove 19, so that the pull rod 10 drives the cross rod 25 and the block 9 to move, thereby realizing disassembly.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
