[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-6 The present invention provides the following technical solution: a drone countermeasure shield, including a countermeasure shield body 1, a display screen 2 fixedly connected to the upper middle of one side of the countermeasure shield body 1, a countermeasure switch 3 fixedly connected to the lower middle of one side of the countermeasure shield body 1, handles 4 fixedly connected to both ends of one side of the countermeasure shield body 1, a heat dissipation hole 5 opened at one end of the countermeasure shield body 1, a ventilation component 6 arranged inside the heat dissipation hole 5, and a convenient disassembly and assembly component 7 arranged on the other side of the countermeasure shield body 1.

[0025] Specifically, the ventilation component 6 includes a ventilation seat 61, a ventilation fan 62, a positioning block 63, a dust filter 64, and a fixing component 65. The ventilation seat 61 is fixedly connected inside the heat dissipation hole 5, the ventilation fan 62 is fixedly connected inside the ventilation seat 61, the positioning block 63 is fixedly connected around one side of the ventilation seat 61, the dust filter 64 is tightly inserted inside the positioning block 63, and the fixing component 65 is provided in the middle of the positioning block 63 above one side of the ventilation seat 61.

[0026] By adopting the above technical solution, the ventilation fan 62 is activated, the air is filtered through the dust filter 64, and then enters the square shell of the countermeasure shield body 1, carrying away the heat and being discharged from the air outlet at the other end.

[0027] Specifically, the fixing component 65 includes a fixing rod 651, a pull block 652, and a fixing spring 653. The fixing rod 651 is slidably connected to the middle of the positioning block 63 on one side of the ventilation seat 61. The pull block 652 is fixedly connected to the top of the fixing rod 651. The two ends below the pull block 652 are fixedly connected to the fixing spring 653. The bottom of the fixing spring 653 is fixedly connected to the positioning block 63. The dust filter 64 has a fixing hole on its top that matches the fixing rod 651.

[0028] By adopting the above technical solution, when you want to remove, clean or replace the dust filter 64, you can pull the pull block 652. The pull block 652 stretches the fixing spring 653, so that the fixing rod 651 is disengaged from the fixing hole opened on the top of the dust filter 64. Then the dust filter 64 can be taken out from the frame formed by the positioning block 63 for cleaning and replacement.

[0029] Specifically, the other end of the countermeasure shield body 1 is provided with an air outlet, and a dustproof net is fixedly connected inside the air outlet.

[0030] By adopting the above technical solution, the air outlet facilitates the discharge of air.

[0031] In this embodiment, when in use: the ventilation fan 62 is turned on, the air passes through the dust filter 64 and then enters the square shell of the countermeasure shield body 1, carrying away the heat and being discharged from the air outlet at the other end. When you want to remove, clean or replace the dust filter 64, pull the pull block 652. The pull block 652 stretches the fixing spring 653, causing the fixing rod 651 to disengage from the fixing hole opened above the dust filter 64. Then the dust filter 64 can be taken out from the frame formed by the positioning block 63 for cleaning and replacement. This makes it easy to ventilate and dissipate heat inside the countermeasure shield body 1 during use, and also makes it easy to prevent dust from entering.

[0032] Example 2

[0033] The difference between this embodiment and embodiment 1 is as follows: Specifically, the convenient disassembly and assembly component 7 includes a disassembly and assembly base 71, a disassembly and assembly cover 72, a limiting rod 73, a pressing block 74, a stabilizing slide rod 75, and a limiting spring 76. The disassembly and assembly base 71 is fixedly connected to one side of the countermeasure shield body 1. The disassembly and assembly cover 72 is tightly inserted into the middle of the disassembly and assembly base 71. The limiting rod 73 is slidably connected to the inside of both ends of the disassembly and assembly cover 72. The pressing block 74 is fixedly connected to one side of the limiting rod 73. The pressing block 74 and the disassembly and assembly cover 72 are slidably connected. The stabilizing slide rod 75 is slidably connected to one end of the pressing block 74. The two ends of the stabilizing slide rod 75 are fixedly connected to the disassembly and assembly cover 72 respectively. The limiting spring 76 is fixedly connected to the lower part of the pressing block 74. The lower part of the limiting spring 76 is fixedly connected to the disassembly and assembly cover 72. A limiting hole is opened on one side of the disassembly and assembly base 71 to fit tightly into the limiting rod 73. A guide slide is opened at one end of the limiting rod 73.

[0034] By adopting the above technical solution, by placing a finger above the pressing block 74 inside the disassembly and assembly base 71 and then pressing the pressing block 74, the pressing block 74 compresses the limiting spring 76, and at the same time drives the limiting rod 73 to move away from the limiting hole opened on one side of the disassembly and assembly base 71. Then the disassembly and assembly cover 72 can be removed, thereby allowing for the inspection and maintenance of the components inside the square shell of the countermeasure shield body 1. The stabilizing slide rod 75 facilitates the stable sliding of the pressing block 74. During installation, the disassembly and assembly cover 72 is directly picked up and engaged with the disassembly and assembly base 71. Then, the disassembly and assembly cover 72 is pressed. Under the action of the guide slide at one end of the limiting rod 73, the limiting rod 73 and the disassembly and assembly base 71 abut against each other, which will drive the limiting rod 73 to move automatically and compress the limiting spring 76 until the disassembly and assembly cover 72 moves to coincide with the limiting hole on one side of the disassembly and assembly base 71. The limiting spring 76 returns to its original position, driving the limiting rod 73 to insert into the limiting hole, thus completing the fixation.

[0035] Specifically, one side of the disassembly cover 72 is symmetrically and fixedly connected with a positioning rod, and one side of the countermeasure shield body 1 is provided with a positioning hole that matches the positioning rod.

[0036] By adopting the above technical solution, the positioning rod and positioning hole cooperate to facilitate the positioning of the cover 72 during installation.

[0037] In this embodiment, during use: Place your finger above the pressing block 74 inside the disassembly / assembly base 71, then press the pressing block 74. The pressing block 74 compresses the limiting spring 76, simultaneously moving the limiting rod 73 away from the limiting hole on one side of the disassembly / assembly base 71. Then, the disassembly / assembly cover 72 can be removed, allowing for the inspection and maintenance of components inside the square housing of the countermeasures shield body 1. The stabilizing slide rod 75 facilitates the stable sliding of the pressing block 74. During installation, simply remove the disassembly / assembly cover 72 and the disassembly / assembly base 71. Then press the disassembly cover 72. Under the action of the guide slide at one end of the limiting rod 73, the limiting rod 73 and the disassembly base 71 abut against each other, which will drive the limiting rod 73 to move automatically and compress the limiting spring 76 until the disassembly cover 72 moves to the limit hole on one side of the limiting rod 73 and the disassembly base 71. The limiting spring 76 returns to its original position and drives the limiting rod 73 to be inserted into the limiting hole to complete the fixation. This makes it easy to open and close the square shell of the countermeasure shield body 1 for internal inspection and maintenance when the device is in use.

[0038] The structure and operating principle of the countermeasure shield body 1, display screen 2, countermeasure switch 3, and handle 4 in this utility model have been disclosed in a portable drone countermeasure shield disclosed in Chinese patent application number 202122319978.2. Its working principle is as follows: the countermeasure shield body 1 includes a square shell, a power module, an RF module, and an antenna module. When in use, the power module is used to supply power to the RF module and the antenna module. The RF module generates an interference signal according to the signal frequency band provided by the detection device and then emits it through the antenna module. The handle 4 facilitates the carrying of the countermeasure shield. The countermeasure switch 3 is used to control the opening and closing of the antenna module, and the display screen 2 can display the voltage and power.

[0039] The working principle and usage process of this utility model: This utility model is used for countering drones. The handle 2 facilitates carrying the countermeasure shield. The countermeasure switch 3 controls the opening and closing of the antenna module. The display screen 4 displays voltage and power. The ventilation component 6 facilitates ventilation and heat dissipation inside the countermeasure shield body 1. The convenient disassembly and assembly component 7 facilitates opening the square shell of the countermeasure shield body 1 for internal inspection and maintenance. When using the ventilation component 6, the ventilation fan 62 is activated. The air is filtered through the dust filter 64 and then enters the square shell of the countermeasure shield body 1, carrying away heat and exiting from the air outlet at the other end. To remove, clean, or replace the dust filter 64, pull the pull block 652. The pull block 652 stretches the fixing spring 653, causing the fixing rod 651 to disengage from the fixing hole above the dust filter 64. Then, the dust filter 64 can be removed from the frame formed by the positioning block 63 for cleaning and replacement. This device facilitates ventilation and heat dissipation inside the countermeasure shield body 1 during use. To prevent dust from entering and facilitate the disassembly and assembly of component 7, when using it, place your finger above the pressing block 74 inside the disassembly and assembly base 71, and then press the pressing block 74. The pressing block 74 compresses the limiting spring 76, and at the same time, it moves the limiting rod 73 to move away from the limiting hole opened on one side of the disassembly and assembly base 71. Then, the disassembly and assembly cover 72 can be removed, thereby allowing for the inspection and maintenance of the components inside the square shell of the countermeasure shield body 1. The stabilizing slide rod 75 facilitates the stable sliding of the pressing block 74. During installation, simply take out the disassembly and assembly cover 72 and the disassembly and assembly cover 72. When the mounting base 71 is engaged, the disassembly cover 72 is pressed. Under the action of the guide slide at one end of the limiting rod 73, the limiting rod 73 and the disassembly base 71 abut against each other, which will drive the limiting rod 73 to move automatically and compress the limiting spring 76 until the disassembly cover 72 moves to the limit hole on one side of the limiting rod 73 and the disassembly base 71. The limiting spring 76 returns to its original position, driving the limiting rod 73 to insert into the limiting hole and complete the fixation. This makes it easy to open and close the square shell of the countermeasure shield body 1 for internal inspection and maintenance when the device is in use.
