Description

Technical Field

[0001] This application relates to the technical field of radar and related equipment, and in particular to a telephone recording box for radar. Background Technology

[0002] In specialized fields such as civil aviation air traffic control, where security and data integrity are paramount, radar systems, as core equipment, require dedicated recording devices to preserve critical data. These recording devices must be precisely adapted to the radar system's technical architecture. Their core function is to collect and store voice data during air traffic control operations, ensuring its correlation with radar operational data. Currently, mainstream dedicated devices include the Edison500 recording device and the Synway radar data recording card. The former can directly collect and securely store radar voice data from civil aviation air traffic control centers, while the latter passively connects to radar lines and, when paired with a voice board, forms a complete recording and monitoring system, providing end-to-end data traceability support for air traffic control.

[0003] The current radar-compatible telephone recording box has a mature structural design. Its core components include a box body with an opening on the top and a removable cover. Internally, it integrates a main circuit board, a power control circuit board, and a hard drive for storing recording data. To ensure the stability of the hard drive installation, a dedicated mounting cavity is provided on the inner wall of the box for the hard drive to be inserted. An installation port communicating with this cavity is located on the front of the box, allowing the hard drive to be inserted. Simultaneously, a cover plate is rotatably mounted on the front of the box to seal the installation port and protect the hard drive. Ventilation vents are designed on the left and right sides to reduce the operating temperature of the internal electronic components through air circulation, preventing overheating from affecting the normal operation of the equipment.

[0004] In practical use, because the hard drive needs to be securely installed to prevent shaking during operation, the gap between it and the inner wall of the mounting cavity is designed to be extremely small. This means that after recording is complete, the operator cannot directly grasp the hard drive with their fingers. To remove the hard drive and export data, specialized tools such as tweezers must be used. This not only increases the operation steps and tool preparation costs, but also may accidentally damage the hard drive interface or the inner wall of the mounting cavity during tool use, reducing the efficiency and lifespan of the equipment. There is room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a telephone recording box for radar, which solves the problem that removing the hard drive is cumbersome and may damage the device.

[0006] The radar telephone recording box provided in this application adopts the following technical solution: A radar telephone recording box includes a box body with an open top and a detachable cover installed inside the box body. A main circuit board, a branch circuit board, and a hard disk for collecting recordings are fixed to the bottom wall of the box body. The inner wall of the box body has a mounting cavity for the hard disk to be inserted, and several connection ports are provided on the rear side. The front side of the box body has a mounting opening communicating with the mounting cavity, and a cover plate rotatably installed to seal the mounting opening. Several heat dissipation holes are provided on the vertical side of the box body near the mounting cavity. A sliding mechanism on the inner wall of the mounting cavity allows for easy access to the recording device. A push plate that slides back and forth in the direction of the mounting opening has a plug fixedly mounted on its side facing the mounting opening, and a socket for the plug to be inserted is fixedly mounted on the hard drive; a square lever is fixedly mounted on the top surface of the push plate, and a guide slot for the square lever to pass through is opened on the cover; a protective plate is provided above the cover, and a square slot for the upper end of the square lever to be inserted is opened on the bottom surface of the protective plate; when the protective plate moves the square lever, it protects the upper opening of the guide slot, and the protective plate is in a state perpendicular to the front side of the box body at this time.

[0007] By adopting the above technical solution, no special tools are needed. Operators only need to open the cover, and the protective plate above the cover can drive the square lever, which in turn pulls the push plate inside the mounting cavity to slide back and forth along the guide direction, causing the hard drive to move towards the mounting opening and protrude, allowing it to be removed directly by hand. This greatly simplifies the operation steps, reduces tool preparation costs, and avoids accidental damage to the hard drive interface or the inner wall of the mounting cavity during tool use, effectively improving equipment efficiency and service life. At the same time, when the protective plate drives the square lever to slide, it can also protect the upper opening of the guide groove on the cover, preventing dust and debris from entering the box through the groove and affecting the operation of electronic components.

[0008] Optionally, guide notches are provided on the left and right inner walls of the mounting cavity for the push plate and the left and right sides of the hard disk to be inserted.

[0009] By adopting the above technical solution, the guide notch can accurately limit and guide the left and right sides of the push plate and the hard drive, effectively constraining their sliding trajectory, avoiding deviation, jamming or shaking during the sliding process, ensuring the stability and smooth sliding of the push plate and the hard drive, and further improving the stability of the hard drive after installation, preventing it from affecting the data storage security due to displacement during operation, and adapting to the high requirements of radar recording equipment for structural stability.

[0010] Optionally, a guide sleeve is fixed on the back side of the push plate, and a guide hole is provided on the rear wall of the mounting cavity for the guide sleeve to pass through.

[0011] By adopting the above technical solution, the cooperation between the guide sleeve and the guide hole forms a secondary guide limit, further constraining the sliding trajectory of the push plate and preventing tilting or offset during sliding. This ensures the smoothness and precision of the push plate driving the hard drive in reciprocating motion. Simultaneously, this structure enhances the structural stability of the push plate after installation, preventing deformation or loosening after long-term use. This indirectly improves the reliability of the connection between the hard drive and the push plate connector, meeting the high requirements of radar recording equipment for component connection stability.

[0012] Optionally, a baffle is rotatably mounted on the lower edge of the back side of the box. The baffle can be rotated upwards to a vertical state for protecting the connection port and downwards to a horizontal state for collecting and storing cables. The box is provided with a locking device to limit the vertical position of the baffle. When the baffle is in the horizontal state, a receiving groove is opened on the top surface. A limiting plate is rotatably mounted on the inner wall of the receiving groove. When the baffle is in the horizontal state, the limiting plate rotates out of the receiving groove to the vertical state and is fixed. When the baffle is in the vertical state, it rotates back into the receiving groove for storage.

[0013] By adopting the above technical solution, the baffle can switch between vertical protection and horizontal cable management. When vertical, it is fixed by locking components to protect the wiring port; when horizontal, the limiting plate rotates out. The two work together to achieve orderly cable management and avoid messy tangling. When not in use, the limiting plate can be stored in the receiving groove without occupying extra space. This design takes into account the protection of the wiring port, the neatness of the cables, and the space utilization rate, and is suitable for the multi-scenario use needs of radar recording equipment.

[0014] Optionally, a positioning plate is fixed on the outer side of the baffle when it is turned into the receiving sink, and a positioning through hole is opened on the back side of the box body; the positioning plate passes through the positioning through hole when the baffle is in a vertical state and the baffle is in the receiving sink; a positioning groove is opened on one side of the positioning plate inside the box body, and the locking member includes a locking rod that slides on the inner wall of the back side of the box body and an elastic pressing member that drives the locking rod to slide into the positioning groove. A control member is provided on the guide sleeve, and when the push plate slides toward the back side, the locking rod is driven to slide out of the positioning groove through the control member.

[0015] By adopting the above technical solution, on the one hand, the cooperation between the positioning plate and the positioning through hole provides precise positioning for the vertical state of the baffle. The elastic pressing component drives the locking rod to slide into the positioning groove, realizing a stable lock on the baffle and effectively ensuring the reliability of the connection port protection during transportation or when idle. On the other hand, through the linkage between the control component on the guide sleeve and the locking rod, when the push plate slides to the back side, it can drive the locking rod to disengage from the positioning groove, unlocking the baffle without additional operation and realizing a quick switch between protection and collection states. This structure not only ensures the connection stability of the baffle in both states, but also simplifies the operation process. At the same time, the mechanical linkage reduces manual intervention and lowers the probability of operational errors, adapting to the dual requirements of radar recording equipment for structural reliability and ease of operation.

[0016] Optionally, the elastic compression member includes a first spring in a compressed state, a guide plate fixed to the inner wall of the box, and a protrusion plate fixed to the locking rod; the guide plate has a limiting hole for the locking rod to pass through, the protrusion plate is located on the side of the guide plate facing the positioning plate, and the two ends of the first spring are fixedly connected to the sides of the protrusion plate and the positioning plate that are close to each other.

[0017] By adopting the above technical solution, the first spring in its compressed state can continuously apply elastic force to the protruding plate, pushing the locking rod to slide stably into the positioning groove, ensuring reliable locking of the baffle in its vertical state; the limiting hole of the guide plate provides precise guidance for the locking rod, avoiding deviation and jamming during sliding, and ensuring smooth locking and unlocking actions; the protruding plate not only provides a stable force support point for the first spring, but also limits the sliding stroke of the locking rod, preventing excessive displacement that could cause structural damage. The overall structure is simple and reliable, achieving automatic locking through spring force without the need for additional fixing operations, and is suitable for the stability and convenience requirements of radar recording equipment.

[0018] Optionally, the control component includes a control rod fixed to the outer periphery of the guide sleeve, a locking protrusion fixed to the outer periphery of the locking rod, and a guide slope provided on the edge of the locking protrusion; a third spring in a compressed state is fixed to the back side of the push plate; the end of the locking rod is pressed along the guide slope when the push plate slides backward against the elastic force of the third spring, causing the locking rod to slide in a direction away from the positioning plate; the protective plate can drive the push plate to stretch the third spring and slide forward, causing the front edge of the hard disk to protrude.

[0019] By adopting the above technical solution, the compressed third spring provides a reset force for the push plate, ensuring the stability of the hard drive after installation. The control lever cooperates with the locking protrusion with a guide ramp, and the baffle is automatically unlocked by the ramp when the push plate slides backward, without the need for additional unlocking steps. The protective plate drives the push plate to stretch the spring forward, causing the hard drive to protrude, enabling tool-free quick loading and unloading. The guide ramp design ensures smooth pressing action and avoids jamming. The overall structure simplifies the operation process through mechanical linkage, while the elasticity of the third spring ensures precise and controllable action of each component. This improves the efficiency of equipment use and avoids structural damage caused by human error, adapting to the dual requirements of radar recording equipment for convenience and reliability.

[0020] Optionally, a storage cavity is formed on the top surface of the box near the heat dissipation hole. A horizontally sliding sealing plate is installed in the storage cavity. The sealing plate has a sealing hole that coincides with the heat dissipation hole. A second spring in a stretched state is provided in the storage cavity. The two ends of the second spring are fixedly connected to the back side of the sealing plate and the inner wall of the back side of the storage cavity, respectively. A bent protrusion that bends away from the box is vertically fixed on the top surface of the sealing plate. The protective plate can be adjusted to be parallel to the front side of the box and is locked in place with the upper end of the square lever. One side of the protective plate extends above the bent protrusion. A positioning notch is formed on the bottom surface of the protective plate. When the bent protrusion is engaged with the positioning notch, the sealing hole is misaligned with the heat dissipation hole. When the bent protrusion is disengaged from the positioning notch, the second spring pulls the sealing plate to make the sealing hole coincide with the heat dissipation hole.

[0021] By adopting the above technical solution, during transportation, the protective plate is parallel and secured to the front of the box, and the positioning notch engages with the bent protruding rod, causing the sealing plate to be misaligned and blocking the heat dissipation holes to prevent dust from entering. During application, the protective plate rotates to a vertical position, the protruding rod disengages from the notch, and the stretched second spring pulls the sealing plate back to its original position, aligning the sealing hole with the heat dissipation hole for rapid heat dissipation. The overall design, through the linkage between the protective plate and the sealing plate, allows for state switching without additional operation. The structure is simple and the movements are precise, ensuring the cleanliness of the equipment's interior during transportation while meeting the heat dissipation requirements of the radar recording equipment during operation, thus adapting to high reliability requirements.

[0022] Optionally, a first retaining ring is fixedly provided on the side of the baffle facing the heat dissipation hole, an extension plate is fixedly provided on the front side of the sealing plate, a second retaining ring is fixedly provided on the front side of the extension plate, and a communication opening is provided on the front side of the box body to communicate with the storage cavity and allow the second retaining ring to protrude; a traction rope is provided on the outside of the box body, and hooks are fixedly provided at both ends of the traction rope; when the second retaining ring is bent and inserted into the positioning notch, it protrudes from the communication opening, and the hooks on the traction rope can engage with the first retaining ring and the second retaining ring respectively.

[0023] By adopting the above technical solution, a temporary handling handle can be quickly constructed using a traction rope, improving the ease of equipment movement. When the bent protruding rod is engaged with the positioning notch, the second retaining ring protrudes from the connecting port, and the hooks at both ends of the traction rope can engage with the first and second retaining rings respectively, forming a stable traction structure that facilitates equipment handling by operators. This design eliminates the need for additional fixed handles, saves space, and leverages existing components for functional expansion, balancing ease of handling with structural simplicity, and is suitable for the mobile use needs of radar recording equipment.

[0024] Optionally, the top surface of the protective plate is provided with a receiving groove for folding and storing the traction rope, and a sealing plate that can be detachably installed to block the opening of the receiving groove.

[0025] By adopting the above technical solution, the traction cable can be folded and stored in the receiving slot, preventing it from becoming tangled or lost when not in use. The sealing plate can seal the opening of the receiving slot, preventing dust and debris from entering the slot and contaminating the traction cable. This design balances storage neatness and protection, does not occupy extra space, keeps the equipment's appearance clean, and is suitable for the structural practicality and cleanliness requirements of radar recording equipment.

[0026] In summary, this application includes the following beneficial technical effects: This application requires no special tools. Operators only need to open the cover and use the protective plate above the cover to drive the square lever, which in turn pulls the push plate in the installation cavity to slide back and forth along the guide direction, causing the hard drive to move towards the installation port and protrude. It can then be removed by hand, which greatly simplifies the operation steps, reduces tool preparation costs, avoids accidental damage to the hard drive interface or the inner wall of the installation cavity during tool use, and effectively improves the efficiency and service life of the equipment.

Detailed Implementation

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] Example: Reference Figure 1 A radar telephone recording box includes a box body 1 with an opening on the top, a box cover 2 detachably installed inside the box body 1, and a control element 3 inside the box body 1. The control element 3 includes a main circuit board 31, a branch circuit board 32, and a hard disk 33 for collecting recordings, all fixed to the bottom wall of the box body 1. The inner wall of the box body 1 has a mounting cavity 11 for the hard disk 33 to be inserted, and a plurality of wiring ports 13 are opened on the rear side. The front side of the box body 1 has a mounting port 12 communicating with the mounting cavity 11, and a cover plate 14 rotatably installed to seal the mounting port 12. A plurality of heat dissipation holes 15 are opened on the vertical side of the box body 1 near the mounting cavity 11. An adjustment assembly 4 is provided inside the mounting cavity 11. The adjustment assembly 4 includes a push plate 41 that slides on the inner wall of the mounting cavity 11 and can slide back and forth towards the mounting opening 12. A plug 411 is fixed on the side of the push plate 41 facing the mounting opening 12. A socket 331 for the plug 411 to be inserted is fixed on the hard disk 33. A square lever 42 is fixed on the top surface of the push plate 41. A guide groove 21 for the square lever 42 to pass through is opened on the cover 2. A protective plate 43 is provided above the cover 2. The bottom surface of the protective plate 43 is detachably connected to the upper surface of the square lever 42. When it is necessary to remove the hard drive 33 from the mounting cavity 11, first open the cover plate 14, then control the protective plate 43 to slide forward, so that the front edge of the hard drive 33 protrudes from the mounting port 12; and when the protective plate 43 drives the square lever 42 to slide, it protects the upper opening of the guide groove 21, and the protective plate 43 is in a state perpendicular to the front of the box 1 at this time.

[0031] Reference Figure 2 and Figure 4 The bottom surface of the protective plate 43 is provided with a square slot 431 for inserting the upper end of the square lever 42; the left and right inner walls of the mounting cavity 11 are provided with guide notches 111 for the push plate 41 and the hard disk 33 to be inserted into the left and right sides, wherein a guide sleeve 412 is fixed on the back side of the push plate 41, and a guide hole is provided on the rear wall of the mounting cavity 11 for the guide sleeve 412 to pass through; thereby improving the stability of the push plate 41 and the hard disk 33 when they are slidably placed in the mounting cavity 11.

[0032] Reference Figure 5 , Figure 6 and Figure 7 The back of the box 1 is provided with a support assembly 5, wherein the support assembly 5 includes a baffle 51 rotatably mounted on the lower edge of the back of the box 1, wherein the baffle 51 can be rotated upward to a vertical state for protecting the connection port 13, and rotated downward to a horizontal state for collecting and storing cables. The box 1 is provided with a locking member 6 for limiting the vertical state of the baffle 51; when the baffle 51 is in the horizontal state, a receiving groove 511 is opened on the top surface, and a limiting plate 52 is rotatably mounted on the inner wall of the receiving groove 511. When using the recording box, first adjust the baffle 51 to a horizontal position, then rotate the limiting plate 52 out of the receiving groove 511 to a vertical position and fix it. In this way, the baffle 51 and the limiting plate 52 are used together to collect the external cables on the rear side. When the recording box is in the factory shipping state, first rotate the limiting plate 52 into the receiving groove 511, and then adjust the baffle 51 to a vertical position to reduce the overall volume and reduce transportation costs.

[0033] Reference Figure 5 , Figure 7 and Figure 8 When the baffle 51 is in the receiving sink 511, a positioning plate 53 is fixed on its outer side, and a positioning through hole 16 is opened on the back side of the box body 1; when the baffle 51 is in the vertical state and the baffle 51 is in the receiving sink 511 (that is, the factory shipping state), the positioning plate 53 passes through the positioning through hole 16. The positioning plate 53 has a positioning groove 531 on one side inside the box 1. The locking member 6 includes a locking rod 61 that slides on the inner wall of the back side of the box 1 and an elastic extrusion member 62 that drives the locking rod 61 into the positioning groove 531. The guide sleeve 412 is provided with a control member 63, which includes a control rod 631 fixed on the outer periphery of the guide sleeve 412. A locking protrusion 64 is fixed on the outer periphery of the locking rod 61. A guide slope 641 is provided on the edge of the locking protrusion 64. A third spring 65 in a compressed state is fixed on the back side of the push plate 41. When the push plate 41 slides backward against the third spring 65, the end of the locking rod 61 is pressed along the guide slope 641, causing the locking rod 61 to slide away from the positioning plate 53, and then causing the locking rod 61 to slide out of the positioning groove 531; when it is necessary to remove the hard disk 33, the operator applies force to make the protective plate 43 drive the push plate 41 to stretch the third spring 65 and slide forward until the front edge of the hard disk 33 protrudes.

[0034] Reference Figure 7 The elastic compression member 62 includes a first spring 621 in a compressed state, a guide plate 622 fixed on the inner wall of the box 1, and a protruding plate 623 fixed on the locking rod 61. The guide plate 622 has a limiting hole for the locking rod 61 to pass through. The protruding plate 623 is located on the side of the guide plate 622 facing the positioning plate 53. The two ends of the first spring 621 are fixedly connected to the protruding plate 623 and the side of the positioning plate 53 that are close to each other.

[0035] Reference Figure 9 , Figure 10 and Figure 11 The top surface of the box body 1 near the heat dissipation hole 15 is provided with a storage cavity 17 and a sealing member 7 located in the storage cavity 17. The sealing member 7 includes a sealing plate 71 that is located in the storage cavity 17 and can slide horizontally. The sealing plate 71 has a sealing hole 711 that can coincide with the heat dissipation hole 15. The storage cavity 17 is provided with a second spring 72 in a stretched state. The two ends of the second spring 72 are fixedly connected to the back side of the sealing plate 71 and the inner wall of the back side of the storage cavity 17, respectively. A bent protrusion 712 that bends away from the box body 1 is vertically fixed on the top surface of the sealing plate 71. The rebound force of the second spring 72 is less than that of the third spring 65. The protective plate 43 can be adjusted to be parallel to the front side of the box 1 and locked to the upper end of the square lever 42. One side of the protective plate 43 extends above the bent protrusion 712. A positioning notch 432 located above the bent protrusion 712 is provided on the bottom surface of the protective plate 43. When the recording box is shipped from the factory, the protective plate 43 is adjusted to be parallel to the front side of the box body 1. At this time, the bending protrusion 712 is pulled to be directly below the positioning notch 432, so that the bending protrusion 712 is interference-fitted into the positioning notch 432. At this time, the sealing hole 711 is misaligned with the heat dissipation hole 15. When the recording box is used, the protective plate 43 is adjusted to be perpendicular to the front side of the box body 1. At this time, the bending protrusion 712 is disengaged from the positioning notch 432. Then, the second spring 72 pulls the sealing plate 71 so that the sealing hole 711 coincides with the heat dissipation hole 15.

[0036] Reference Figure 10 , Figure 11 and Figure 12 A first retaining ring 512 is fixed on the side of the baffle 51 facing the heat dissipation hole 15. An extension plate 73 is fixed on the front side of the sealing plate 71. A second retaining ring 731 is fixed on the front side of the extension plate 73. A connecting opening 171 is opened on the front side of the box body 1, which communicates with the storage cavity 17 and allows the second retaining ring 731 to protrude. A nylon traction rope 74 is provided on the outside of the box body 1, and hooks 741 are fixed at both ends of the traction rope 74. A receiving groove 433 for folding and storing the traction rope 74 is opened on the top surface of the protective plate 43, and a sealing plate 434 is detachably installed to seal the opening of the receiving groove 433. When the recording box needs to be moved, the protective plate 43 is adjusted to be perpendicular to the front side of the box body 1, and the bent protrusion 712 is inserted into the positioning notch 432. At this time, the second retaining ring 731 protrudes from the connecting port 171. Then, the traction rope 74 is taken out from the receiving groove 433, so that the hook 741 on the traction rope 74 can be engaged with the first retaining ring 512 and the second retaining ring 731 respectively. At this time, the traction rope 74 can be used as a "traction handle" to make it easier to move the recording box.

[0037] The implementation principle of this application embodiment is as follows: Factory shipping condition: The protective plate 43 is parallel and secured to the front of the box body 1. Its positioning notch 432 engages with the bent protrusion 712 of the sealing plate 71, causing the sealing hole 711 to be misaligned with the heat dissipation hole 15, preventing dust from entering during transportation. The baffle 51 is vertically stored, and the positioning plate 53 passes through the positioning through hole 16 of the box body 1. The locking rod 61 slides into the positioning groove 531 and locks under the action of the first spring 621. The limiting plate 52 rotates into the receiving groove 511 of the baffle 51, reducing the overall volume and transportation costs. The traction rope 74 is folded and stored in the receiving groove 433 of the protective plate 43 and sealed by the sealing plate 434. During temporary handling, the traction rope 74 is removed, and the hook 741 connects the first retaining ring 512 of the baffle 51 and the second retaining ring 731 of the sealing plate 71 to form a traction handle.

[0038] Actual application state: Adjust the protective plate 43 to be perpendicular to the front side of the box 1, bend the protruding rod 712 to disengage from the positioning notch 432, the second spring 72 pulls the sealing plate 71 to make the sealing hole 711 coincide with the heat dissipation hole 15, so as to achieve heat dissipation; the protective plate 43 drives the square lever 42 to slide backward against the elastic force of the third spring 65. At this time, the control rod 631 on the guide sleeve 412 squeezes the locking protrusion 64 through the guide inclined surface 641, so that the locking rod 61 disengages from the positioning groove 531, and the baffle 51 can be rotated to the horizontal; unfold the limiting plate 52, and the baffle 51 and the limiting plate 52 together collect the cable.

[0039] Hard drive 33 installation and removal: Open the cover plate 14, apply force to push the protective plate 43 to drive the push plate 41 to stretch the third spring 65 and move forward. The hard drive 33 will protrude from the installation port 12 and can be removed. When installing, insert the hard drive 33 into the installation cavity 11 so that the plug 411 is connected to the hard drive 33 socket 331.
