Description

Technical Field

[0001] This utility model relates to the field of signal detection technology, specifically a handheld signal detection device. Background Technology

[0002] In scenarios such as sporting events and international conferences, it is necessary to monitor wireless signal activity in real time to prevent drone interference or illegal communication. This is where signal detection devices come in. When potential drone interference or illegal communication is detected, the device will issue a warning or alarm signal to remind relevant personnel to take timely action.

[0003] Existing handheld signal detection devices are often designed with handheld convenience in mind, resulting in a lack of additional functions. This makes them unsuitable for outdoor use, such as lacking a waterproof structure to protect against rain or impacts. Furthermore, they are difficult to place in vehicle-mounted or fixed detection systems, requiring constant handheld operation to keep the antenna pointing upwards and maintain signal detection range. This hinders other operations and reduces usability. While the device can detect different frequency electromagnetic signals by replacing the antenna, there are typically two ways to connect it: one is by directly plugging and unplugging the antenna, which can lead to instability and easy detachment; the other is by fixing it with structural components and screws, requiring tools for disassembly and replacement, making the process complex and slow, further reducing usability. Utility Model Content

[0004] The purpose of this invention is to provide a handheld signal detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a handheld signal detection device, comprising:

[0006] A housing, wherein a cover plate is installed on one side of the housing, and an outer shell is fixedly connected to the top of the housing;

[0007] A circuit board is installed inside the housing, and a processing module and a positioning module are provided on the outside of the circuit board. An antenna is provided on the top of the housing.

[0008] The battery is installed on the inside of the cover plate, and a display screen is provided on the inside of the cover plate;

[0009] A sealing assembly is provided on one side of the housing and the cover plate.

[0010] A connecting block is installed on the outside of the antenna, and an adjustment assembly is provided on the inside of the housing. Two sets of transmission assemblies are symmetrically arranged on the inside of the adjustment assembly.

[0011] The positioning blocks are located on the outside of the transmission assembly, and there are two of them. The inner side of the connecting block has two symmetrical limiting grooves for connecting with the positioning blocks.

[0012] A spring is positioned between the two positioning blocks, a guide assembly is provided on the bottom inner side of the housing, and a connecting assembly is provided on the bottom of the antenna.

[0013] Preferably, the sealing assembly includes a sealing gasket fixed to one side of the cover plate, and a sealing groove is provided on one side of the housing, with the outer side of the sealing gasket slidably connected to the inner side of the sealing groove.

[0014] Preferably, the support assembly includes a support frame that rotates inside the connecting seat, and two anti-slip pads are fixedly connected to the bottom of the housing.

[0015] Preferably, the adjustment component includes a slider that slides on the top of the housing, and a movable base is fixedly connected to the bottom of the slider.

[0016] Preferably, the transmission assembly includes a connecting rod that rotates inside the movable seat, the other end of the connecting rod being rotatably connected to a rotating seat, and the outer side of the rotating seat being fixedly connected to the outer side of the positioning block.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] This invention utilizes a sliding button that moves backward, causing the sliding seat to move synchronously. One end of the connecting rod then moves with the sliding seat and rotates along its inner side. The other end of the connecting rod, due to the change in rotation angle, moves as a whole. Simultaneously, the rotating seat compresses the positioning block against the spring, causing it to move inward and disengage from the limiting groove. This allows the connecting block to be lifted upward, enabling the plug to be pulled out from the interface, thus completing antenna removal and improving the ease of antenna replacement. The sealing component effectively prevents water leakage at the connection between the housing and the cover, improving the device's waterproof performance. The support component creates an angle between the housing and the contact surface, providing stable support. The protective pad absorbs the impact of drops or collisions, protecting the delicate internal components and ensuring the device's stability in various scenarios. Attached Figure Description

[0026] 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.

[0027] Please see Figure 1-4 As shown, a handheld signal detection device includes a housing 1, which serves as the main frame of the device, providing structural support and protecting internal components. A cover plate 2 is installed on one side of the housing 1 to close the opening of the housing 1, forming a sealed space inside the device, and is connected to the housing 1 by a snap-fit. An outer shell 13 is fixedly connected to the top of the housing 1. A circuit board 3 is installed inside the housing 1, and a processing module 5 and a positioning module 6 are arranged on the outside of the circuit board 3. The processing module 5 is responsible for signal analysis, algorithm operation, and system control. For example, it processes the raw data from the detection signal and converts it into readable information for output to the display screen 8. The positioning module 6 is used to provide geographical location information for marking the coordinates of the detection data or realizing device tracking. This is prior art and will not be described in detail here. An antenna 4 is arranged on the top of the housing 1 for... To enhance the signal detection capability of the device; battery 7, installed inside the cover plate 2, provides power to the device. The inside of the cover plate 2 is equipped with a display screen 8, which supports touch operation and uses a high-resolution screen to display detection results (such as signal strength, positioning coordinates), device status (battery level, connection status) and operation menu; sealing component 9 is set on one side of the housing 1 and the cover plate 2. Four protective pads 10 are installed on the outer sides of the housing 1 and the cover plate 2 to prevent the device from being damaged by collision. They are fixedly installed at the four corners of the housing 1 and the cover plate 2, usually made of silicone material, which takes into account both cushioning and wear resistance, and is used to absorb the impact force when falling or colliding, protecting the precision components inside the device; a connecting seat 11 is fixedly connected to one side of the housing 1, and a support component 12 for supporting the housing 1 is provided inside the connecting seat 11.

[0028] A connecting block 14 is installed on the outside of the antenna 4. An adjustment component 15 is provided on the inside of the housing 13. Two sets of transmission components 16 are symmetrically arranged on the inside of the adjustment component 15. Two positioning blocks 17 are located on the outside of the transmission components 16 and slide along a channel provided on the inside of the housing 13. The slot size of the channel is the same as the outer size of the positioning block 17, so that the positioning block 17 can move stably. Two limiting grooves 18 are symmetrically opened on the inside of the connecting block 14 for connecting with the positioning blocks 17. A spring 19 is located in the middle of the two positioning blocks 17, and its two ends are fixedly connected to the positioning blocks 17 respectively. It supports the positioning blocks 17 through its elasticity and pushes the positioning blocks 17 into the inside of the limiting grooves 18 to form a connection. A guide component 20 is provided on the bottom of the inside of the two housings 13, and a connecting component 21 is provided on the bottom of the antenna 4.

[0029] The sealing assembly 9 includes a sealing gasket 91 fixed to one side of the cover plate 2. A sealing groove 92 is provided on one side of the housing 1. The outer side of the sealing gasket 91 is slidably connected to the inner side of the sealing groove 92. The sealing gasket 91 is made of rubber. After the housing 1 and the cover plate 2 are connected, the sealing gasket 91 is completely inserted into the inner side of the sealing groove 92, filling the gap in the sealing groove 92, effectively preventing water seepage at the connection between the housing 1 and the cover plate 2, and improving the waterproof performance of the device.

[0030] The support assembly 12 includes a support frame 121 that rotates inside the connecting seat 11. Two anti-slip pads 122 are fixedly connected to the bottom of the housing 1. The connecting seat 11 is equipped with damping, so that the support frame 121 needs to be rotated by external force. When the device needs to be placed on a table or vehicle for detection, the support frame 121 can be rotated and unfolded so that the housing 1 forms a certain angle with the contact surface, providing stable support for the housing 1. The anti-slip pads 122 are made of rubber, which can increase the friction between the device and the contact surface when it is placed.

[0031] The adjustment component 15 includes a slider 151 that slides on the top of the housing 13. A movable seat 152 is fixedly connected to the bottom of the slider 151. When the slider 151 is turned, the slider 151 will move synchronously with the movable seat 152. A groove is provided on the top of the housing 13 to guide the slider 151 to slide along a predetermined route. By design, the movable seat 152 can move a greater stroke than the stroke required for the positioning block 17 to disengage from the inner side of the limiting groove 18. When the movable seat 152 moves, the positioning block 17 can be smoothly separated from the limiting groove 18.

[0032] The transmission assembly 16 includes a connecting rod 161 that rotates inside the movable seat 152. The other end of the connecting rod 161 is rotatably connected to a rotating seat 162. The outer side of the rotating seat 162 is fixedly connected to the outer side of the positioning block 17. One end of the connecting rod 161 moves with the movable seat 152 and rotates along the inner side of the movable seat 152. The other end of the connecting rod 161 moves as a whole due to the change in the rotation angle. While the connecting rod 161 moves, it drives the positioning block 17 to move through the rotating seat 162.

[0033] The guide assembly 20 includes a guide block 201 fixed to the bottom of the movable seat 152. A guide groove 202 is provided on the inner bottom of the outer shell 13, and the outer side of the guide block 201 is slidably connected to the inner side of the guide groove 202. When the movable seat 152 moves, it drives the guide block 201 to move synchronously. The guide block 201 will slide along the inner side of the guide groove 202. The guide groove 202 restricts the movement path of the movable seat 152, so that the movable seat 152 can move along a predetermined route.

[0034] The connection component 21 includes a plug 211 located at the bottom of the antenna 4 and an interface 212 located at the top of the housing 1. The outer side of the plug 211 engages with the inner side of the interface 212. The plug 211 establishes an electrical connection with the interface 212 through its internal metal contacts or pins. This connection allows the signal received by the antenna 4 or the signal emitted by the device to be transmitted between the two. The interface 212 is responsible for receiving the signal transmitted from the plug 211 and passing it to the processing module 5 inside the device for processing. The use of the plug 211 and the interface 212 makes it easy to modularly assemble the antenna 4.

[0035] Working principle: When replacing antenna 4, first slide button 151 backward. Simultaneously, slide button 151 moves the moving base 152. Then, one end of connecting rod 161 moves with the moving base 152 and rotates along the inner side of the moving base 152. Due to the change in rotation angle, the other end of connecting rod 161 moves as a whole. As connecting rod 161 moves, the rotating base 162 drives positioning block 17 to press spring 19, moving it inward towards the outer casing 13. This causes positioning block 17 to disengage from the limiting groove 18, freeing connecting block 14 from its limiting position. Then, lift antenna 4 upward, pulling plug 211 out of the interface 212, completing the disassembly of antenna 4. Next, connect the antenna 4 to be installed via plug 211 to interface 212. Finally, release slide button 151, disengaging it from its fixed position. Subsequently, the spring 19 loses its limit and pushes the positioning blocks 17 at both ends to move outward through the accumulated elastic force, thereby driving the transmission component 16 to complete the reset. Then, the positioning block 17 enters the inner side of the limiting groove 18, so that the outer shell 13 and the connecting block 14 form a fixed connection, thereby fixing the antenna 4 and ensuring its stable operation. When detecting interference signals, the antenna 4 first scans the target frequency band to capture electromagnetic signals in the air. The processing module 5 is used to automatically identify parameters such as signal type, frequency, and intensity. The pre-trained algorithm matches the signal characteristics with the interference type in the database. At the same time, the signal intensity is compared with the preset threshold to mark abnormal signals. The positioning module 6 is used to mark the approximate location of the signal source in conjunction with the GPS positioning system. Meanwhile, the display screen 8 provides a spectrum diagram display to help users intuitively understand the signal distribution and interference situation.
