[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0027] like Figures 1 to 6As shown, a radio signal jammer provided by an embodiment of the utility model includes a protective box 1, an interferometer 4 is detachably connected to the interior of the protective box 1, and a protective cover 2 is rotatably connected to the upper end of the protective box 1. By placing the interferometer 4 into the protective box 1 and then rotating the protective cover 2 to close the interior of the protective box 1, the interferometer 4 is protected.

[0028] Two groups of fixing blocks 9 are fixedly installed on both sides of one end of the protective box 1, and a rotating rod 11 is rotatably connected between the two groups of fixing blocks 9. One end of the rotating rod 11 is rotatably connected to a fixing rod 12, and the fixing rod 12 is used to prevent the protective cover 2 from opening. A handle 14 is fixedly installed on the upper surface of the fixing rod 12, and the handle 14 is used to drag the protective box 1, and a docking block 16 is fixedly installed on one end of the lower surface of the fixing rod 12. By pressing the fixing rod 12 against the upper surface of the protective cover 2, and then snapping the clamping assembly 8 into engagement with the docking block 16, the fixing rod 12 can be fixed to the upper surface of the protective cover 2, and the handle 14 on the surface of the fixing rod 12 can be used by workers to lift the protective box 1.

[0029] Both ends of the side walls of the protective box 1 are fixedly installed with a snap-fit ​​assembly 8, which is snap-fitted with the docking block 16. Through the cooperation between the snap-fit ​​assembly 8 and the docking block 16, the fixing rod 12 can make the protective cover 2 completely close to the protective box 1, so that the interferometer 4 inside the protective box 1 is no longer damaged by the outside world.

[0030] Grooves are provided at both ends of the upper surface of the protective box 1, and rotating blocks 3 are rotatably connected in the grooves. The upper surfaces of the two sets of rotating blocks 3 are fixedly connected to the lower surface of the protective cover 2. The protective cover 2 is rotatably connected to the protective box 1 through the rotating blocks 3. When the interferometer 4 inside the protective box 1 needs to be used, the protective cover 2 is first opened, and the protective cover 2 will be turned over by the rotation of the rotating blocks 3, so that the interferometer 4 inside the protective box 1 can be taken out.

[0031] The handles 14 are arranged in a U shape, and a connecting rod 15 is fixedly connected between the two groups of handles 14 for lifting the protective box 1. The handles 14 can be used by workers to lift the protective box 1, so that the workers save physical strength when carrying the protective box 1. At the same time, the connecting rod 15 between the handles 14 can also be used as a second handle for the workers to lift the protective box 1. The handles 14 and the connecting rod 15 can be used as the base of the protective box 1. When the handles 14 and the connecting rod 15 are rotated to the lower surface of the protective box 1 at the same time, a base can be formed for use.

[0032] A communicating shaft hole is opened between the two groups of fixed blocks 9 and the rotating rod 11, and a first shaft 10 is arranged in the shaft hole. The rotating rod 11 is rotatably connected to the two groups of fixed blocks 9 through the first shaft 10. By pulling the rotating rod 11, the rotating rod 11 can be rotated ninety degrees up and down with the assistance of the first shaft 10. After rotating downward, it drives the fixed rod 12 and the handle 14 and the connecting rod 15, and then the handle 14 and the connecting rod 15 stick to the lower surface of the protective box 1, so that a base can be formed for the use of the protective box 1.

[0033] A communicating circular hole is opened between the rotating rod 11 and the fixed rod 12, and a second rotating shaft 13 is arranged in the circular hole. The fixed rod 12 is rotatably connected to the rotating rod 11 through the second rotating shaft 13. The fixed rod 12 can be pulled and then rotated with the assistance of the second rotating shaft 13, so that the fixed rod 12 can be close to the protective cover 2 or away from the protective cover 2.

[0034] A docking hole 17 is provided on the side wall of the docking block 16, and the docking block 16 is engaged with the snap-fit ​​assembly 8 through the docking hole 17. The docking hole 17, in cooperation with the snap-fit ​​assembly 8, fixes the fixing rod 12 on the surface of the protective cover 2, so that the protective cover 2 will not be opened again, thereby achieving the effect of protecting the interferometer 4.

[0035] The snap-on assembly 8 includes a base plate 801, which is fixedly installed at one end of the side wall of the protective box 1. Fixed columns 802 are fixedly installed at both ends of the side wall of the base plate 801. A through hole is opened in the middle end of the side wall of the base plate 801. Fixed plates 804 are fixedly installed on the upper ends of two groups of fixed columns 802. An annular hole is opened in the middle end of the side wall of the fixed plate 804. A connecting column 806 is slidably inserted in the annular hole. A handle 805 is fixedly installed on the upper end of the connecting column 806. When it is necessary to tighten the protective cover 2, the handle 805 is pulled first, and then the connecting column 806 is driven by the handle 805, and then the connecting column 806 drives other components inside the snap-on assembly 8, thereby completing a series of operations.

[0036] The clamping assembly 8 also includes a slider 803, both ends of the side wall of the slider 803 are provided with sliding slot holes, the two sets of sliding slot holes are respectively slidably connected with the two sets of fixed columns 802, the middle end of the side wall of the slider 803 is fixedly connected with the connecting column 806, the middle end of the side wall of the slider 803 is fixedly installed with a spring 807, the connecting column 806 is located at the center end of the spring 807, the upper end of the spring 807 is fixedly connected to one side of the fixed plate 804, the middle end of one side of the slider 803 is fixedly installed with a clamping column 808, the clamping column 80 8 passes through the through hole and is snap-fitted with the docking hole 17. During the sliding process of the connecting column 806, the connecting column 806 drives the slider 803 to slide, so that the snap-in column 808 will move along with it. Then the spring 807 between the slider 803 and the fixed plate 804 is squeezed to generate pressure. Then after the docking block 16 is in place, the handle 805 is released. Under the rebound of the spring 807, the snap-in column 808 moves toward the docking hole 17 and is inserted into the docking hole 17, thus completing the snap-in work.

[0037] Four groups of heat dissipation holes 7 are provided on the lower surface of the protection box 1 . The interferometer 4 will generate heat and be damaged if it works inside the protection box 1 for a long time. Therefore, the heat dissipation holes 7 are provided to dissipate the heat of the interferometer 4 .

[0038] The side wall of the protection box 1 is provided with a plurality of groups of holes 6, and the side wall of the interferometer 4 is provided with a plurality of groups of signal rods 5, which are installed for transmitting interference signals.

[0039] The plurality of signal rods 5 pass through the plurality of holes 6 respectively. The holes 6 are opened to pass the signal rods 5 . The signal rods 5 and the interferometer 4 are two entities. After the interferometer 4 is placed in the protective box 1 , the signal rods 5 are inserted into the holes 6 to dock with the interferometer 4 .

[0040] The above embodiments are only used to help understand the method and core idea of ​​the utility model.
