Description

Technical Field

[0001] The present invention relates to the field of signal testing, and more particularly, to a communication signal testing device. Background Art

[0002] In modern communication networks, especially with the popularization and development of 5G technology, the precise detection of communication signals has become particularly important. Signal strength is one of the key indicators to measure the performance of a communication system. It directly affects the communication quality between devices and base stations, such as connection stability, anti-interference ability, signal latency, and coverage. Precise detection of signal strength not only helps to optimize the performance of the communication network but also quickly discovers and solves potential network failures, thus ensuring user experience and the overall network stability. Therefore, during the installation and maintenance of communication devices, signal detection equipment has become an indispensable tool.

[0003] Currently, there are various signal detection devices on the market for detecting communication signals in different scenarios. Among them, portable 5G signal detection devices are widely used in field tests due to their light weight and easy portability. For example, in the prior art, CN117353846B discloses a portable 5G communication detection device. By designing all function panels in a detachable form and stacking them in a dedicated storage box, the overall volume of the device is reduced. This design indeed improves the portability of the device and can effectively reduce the space occupied during transportation and storage. However, in actual use, this structural design still has many limitations.

[0004] Firstly, when using this detection device, the operator needs to frequently take out the function panels from the storage box and put them back after the detection is completed. This operation process is rather cumbersome, especially in scenarios where quick detection and frequent use are required. The operation efficiency is low, which is likely to cause delays in the detection work. In addition, the connecting components of the function panels are usually exposed, and this exposed design increases the risk of the components being affected by the external environment. Factors such as water vapor erosion and foreign object impact may cause circuit damage, unstable signal transmission, or even equipment failure, seriously affecting the reliability and safety of the detection. Secondly, in actual applications, signal detection equipment usually needs to be fixed on a communication cabinet or other installation surfaces to ensure stability and operation convenience. Existing solutions usually use the method of magnetic adsorption to fix the device on the cabinet door. However, due to the relatively large overall weight of the device, the magnetic force alone is not sufficient to provide enough fixing strength. Especially in an environment with external forces or vibrations, the device may slip off the communication cabinet, which not only affects the detection work but also may cause damage to the device, presenting an obvious safety hazard. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the object of the present invention is to provide a communication signal testing device, which includes a column, a first detection plate and a second detection plate slidably connected to the column, and a first functional component and a second functional component rotatably connected to the column.

[0007] Two first grooves are formed on the back surface of the column, a clamping block is attached to the back surface of the column, support seats are bolted to the groove walls on both sides of the first groove, and a group of guide rods are welded between the two support seats.

[0008] A convex block protrudes from the side of the clamping block facing the column, and the guide rod penetrates through the convex block and is slidably connected to the convex block.

[0009] The first functional component and the second functional component have the same structure, and both include a movable frame. A vertical plate is integrally formed by injection molding between the inner walls at the top and bottom of the movable frame, a horizontal plate is integrally formed by injection molding between the side wall of the movable frame and the vertical plate, and a baffle is fixedly bonded to one side of the movable frame and the vertical plate.

[0010] Two cavity grooves are formed by enclosing between the vertical plate, the horizontal plate and the inner wall of the movable frame. A fixed function panel and a movable function panel are arranged in the cavity grooves. Fixed frames are sleeved on the movable function panels relative to the fixed function panel, and the fixed frames on the fixed function panel and the movable function panel are hinged to each other.

[0011] A lithium battery is built into the column, and a conductive component electrically connected to the lithium battery is built into the lithium battery. The conductive component is used to supply power to the first detection plate, the second detection plate, the first functional component and the second functional component.

[0012] An internal signal detection module is built into the first detection plate, and an external signal detection module is built into the second detection plate.

[0013] The column, the movable frame, the vertical plate, the horizontal plate and the fixed frame are all made of insulating materials, such as phenolic plastics. In this way, during the operation of the device, the insulation performance can be improved, electric shock can be avoided, and the safety performance is high. At the same time, on the premise of ensuring the strength, the overall quality can be reduced so that the device can be better fixed on the cabinet.

[0014] The conductive metal strip, the upper conductive cylinder, the lower conductive cylinder, the first conductive column, the second conductive column, the third conductive column, the fourth conductive column, the third conductive contact, the fourth conductive contact and the fifth conductive column are all made of metal materials, such as copper. In this way, the circuit signal transmission rate can be improved.

[0015] As a preferred technical solution:

[0016] In the communication signal testing device as described above, the cross section of the column is rectangular, the column is a hollow structure, and vertically distributed magnet blocks are embedded on the back of the column.

[0017] Through the above technical solution, when the first detection plate cooperates with the clamping block to fix the entire device on the cabinet, in order to further improve the fixing effect, auxiliary fixing is also performed by the magnetic force generated between the magnet block and the cabinet, thereby preventing the device from falling.

[0018] In the communication signal testing device as described above, a set of sliding grooves are provided on opposite sides of the first detection plate and the second detection plate, and T-shaped sliding bars are protruded from the two side walls of the column, and the sliding bars are embedded in the sliding grooves.

[0019] Through the above technical solution, a rubber strip is bonded to the groove wall of the sliding groove. When the sliding strip slides in the sliding groove, it will contact the rubber strip, which will cause a certain resistance when sliding, so that the first detection plate and the second detection plate can remain in a fixed state after sliding to a certain position, avoiding sliding back and forth and affecting the overall use.

[0020] In the communication signal testing device as described above, the second detection plate is provided with a second groove on a side facing the first detection plate, and a rack is bonded to the end of the second groove.

[0021] A screw rod is connected with a bearing between the two support seats, and the screw rod passes through the convex block and is threadedly connected with the convex block. One end of the screw rod extends into the second groove and is fixed with a gear meshing with the rack by a pin.

[0022] Through the above technical solution, the rack is only arranged on one side of the second groove. This design ensures that the rack and the gear do not contact each other when the second detection plate starts to slide. Only when the second detection plate is completely moved out, the rack and the gear will start to engage, and the second functional component can rotate freely at this time.

[0023] In a communication signal testing device as described above, the conductive component includes a first conductive column, a second conductive column, a third conductive column and a fourth conductive column, the ends of the first conductive column, the second conductive column, the third conductive column and the fourth conductive column are all welded with a third conductive contact, and the side wall of the column is provided with a through hole for the third conductive contact to pass through.

[0024] The bottom ends of the first conductive column and the fourth conductive column are respectively connected to the positive and negative electrodes of the lithium battery.

[0025] Through the above technical solution, the third conductive contact is fixedly bonded to the through hole by insulating glue, so that the third conductive contact can be fixed on the column, and the second conductive column and then the third conductive column can be kept in a fixed state, and the overall insulation can be guaranteed when the circuit signal is transmitted.

[0026] A communication signal testing device as described above, on both the first detection board and the second detection board, a set of fourth conductive contacts that cooperate with the third conductive contacts are provided, and the internal signal detection module within the first detection board and the external signal detection module within the second detection board are both electrically connected to the third conductive contacts.

[0027] Through the above technical solution, in this way, when the first detection board and the second detection board are moved away, the circuit can be accessed through the fourth conductive contacts and the third conductive contacts, and when reset, the circuit can be disconnected again.

[0028] A communication signal testing device as described above, the number of vertical plates is two, a through groove is formed between the two vertical plates, and a conductive metal strip is arranged within the through groove.

[0029] On the inner walls of the movable frames on one side of the vertical plates, grooves are respectively formed, the top end and the bottom end of the conductive metal strip are embedded into the grooves, and an upper conductive cylinder and a lower conductive cylinder are respectively welded to the top end and the bottom end of the conductive metal strip.

[0030] Through the above technical solution, an insulating material, such as insulating ceramic paint, is attached to the outer side of the conductive metal strip. In this way, when the movable frame rotates and unfolds, the exposed parts of the conductive metal strip are covered by the insulating material, thus avoiding accidental contact and electric shock, and further improving the overall safety.

[0031] A communication signal testing device as described above, shaft holes for the upper conductive cylinder and the lower conductive cylinder to penetrate are formed at the top end and the bottom end of the column, and the upper conductive cylinder and the lower conductive cylinder are both connected to the shaft holes by bearings. The top ends of the second conductive column and the third conductive column respectively extend into the two upper conductive cylinders and are in contact with the inner walls of the upper conductive cylinders.

[0032] Through the above technical solution, the upper conductive cylinder and the lower conductive cylinder are of a rotating structure on the column, thereby enabling the movable frame to rotate freely, and further enabling the first functional component and the second functional component to rotate and merge and unfold.

[0033] A communication signal testing device as described above, a "U"-shaped fifth conductive column is fixedly arranged on the inner wall at the bottom end of the column, and the two ends of the fifth conductive column respectively extend into the two lower conductive cylinders and are in contact with the inner walls of the lower conductive cylinders.

[0034] Through the above technical solution, the fifth conductive column can connect the two lower conductive cylinders, thereby enabling the first functional component and the second functional component to be conducted, enabling the first functional component and the second functional component to be in the same circuit, and having a reasonable structure.

[0035] A communication signal testing device as described above, wherein the fixing frame on the fixed function panel is fixed within the movable frame. First conductive contacts and second conductive contacts are respectively arranged on the fixed function panel and the movable function panel. The first conductive contacts and the second conductive contacts both pass through the fixing frame, and the first conductive contacts are in contact with the conductive metal strips.

[0036] Through the above technical solution, the fixed function panel has a fixed structure in the fixing frame. When the movable function panel rotates 90°, the fixed function panel and the movable function panel form a right-angle structure, so that operations can be carried out on both the fixed function panel and the movable function panel simultaneously.

[0037] Compared with the prior art, the present invention has at least the following beneficial effects:

[0038] (1) Multiple fixing mechanisms, significantly improving the stability and safety of the device: The present invention adopts a dual fixing scheme, combining clamping blocks and magnet blocks to ensure the firmness of the device. When the second detection plate and the first detection plate slide to a predetermined position, the clamping blocks will move synchronously with the movement of the detection plates, and firmly clamp the communication cabinet body by the clamping force to prevent sliding or falling off. In addition, the magnet blocks embedded on the back of the device generate a magnetic force with the cabinet body, providing an additional fixing force. This design can maintain stability when the device is subjected to vibrations or external impacts, and is especially suitable for conducting communication signal tests in harsh environments, greatly improving the safety and reliability of operations.

[0039] (2) Integrated functional components, optimizing operation and portability: The present device is designed with a first functional component and a second functional component. These two components include multiple embedded function panels and adopt an integrated structure that can be rotated and unfolded and folded and merged. When the device is stored, the components are merged into a flat and compact structure, which is convenient for storage and transportation; during testing, all function panels can be operated by rotating and unfolding. There is no need for frequent disassembly or installation, significantly simplifying the usage process and facilitating users to quickly deploy and conduct signal detection. This design not only improves the operation efficiency but also reduces the time cost of equipment handling and installation.

[0040] (3) Concealed conductive component design, enhancing insulation and device safety: The conductive components of the device are completely built inside the upright column and the movable frame, and all circuit connection parts are encapsulated with insulating materials. When the device is not in use or in a stored state, the conductive components are not exposed, preventing electrical failures caused by a humid environment or external physical damage. In addition, the insulation design effectively isolates the direct contact between the user and the circuit system, reducing the risk of electric shock and ensuring operation safety. This safety optimization enables the present device to operate stably in various complex environments and meet high-standard electrical safety requirements. Brief Description of the Drawings

Detailed Description of the Invention

[0051] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0052] In the following description, many specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention may be practiced in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited by the specific embodiments disclosed below.

[0053] As Figure 1-2 shown, a communication signal testing device includes a column 1, a first detection plate 2 and a second detection plate 3 slidably connected to the column 1, and a first functional component 4 and a second functional component 5 rotatably connected to the column 1.

[0054] The first detection plate 2 is internally provided with an internal signal detection module, and the second detection plate 3 is internally provided with an external signal detection module.

[0055] During operation, the first detection plate 2 is extended into the communication cabinet, and the second detection plate 3 is located outside the communication cabinet. The first functional component 4 and the second functional component 5 are connected to the internal signal detection module and the external signal detection module to achieve the detection and testing of specific functions such as peak detection, RMS detection, and power detection. The specific test steps and test principles are all disclosed in the prior art CN117353846B, and will not be elaborated here.

[0056] As Figure 3-4 shown, in this embodiment, a set of sliding grooves 38 are provided on the opposite surfaces of the first detection plate 2 and the second detection plate 3. T-shaped sliding strips 37 protrude from the two side walls of the column 1, and the sliding strips 37 are embedded in the sliding grooves 38.

[0057] Since the sliding strips 37 are embedded in the sliding grooves 38, the first detection plate 2 and the second detection plate 3 can be integrated with the column 1. When not in operation, the whole device forms a flat square structure with a small overall size and is convenient to carry. When in operation, the whole device can be unfolded by sliding the first detection plate 2 and the second detection plate 3.

[0058] As Figure 3-4 shown, in this embodiment, two first grooves 28 are provided on the back surface of the column 1. A clamping block 33 is attached to the back surface of the column 1. Support seats 30 are bolted to the groove walls on both sides of the first groove 28. A set of guide rods 31 are welded between the two support seats 30. A convex block 34 protrudes from the side of the clamping block 33 facing the column 1. The guide rods 31 pass through the convex block 34 and are slidably connected to the convex block 34.

[0059] A second groove 29 is provided on the side of the second detection plate 3 facing the first detection plate 2. A rack 36 is adhesively bonded to the end of the second groove 29. A lead screw 32 is rotatably connected between the two support seats 30. The lead screw 32 passes through the convex block 34 and is threadedly connected to the convex block 34. One end of the lead screw 32 extends into the second groove 29 and is fixed with a gear 35 meshing with the rack 36 by a pin.

[0060] When the second detection plate 3 slides within a certain range, the rack 36 will contact and mesh with the gear 35 at this time. As a result, the rack 36 will push the gear 35 to rotate, and the lead screw 32 will rotate synchronously with the gear 35 and drive the convex block 34 to slide along the guide rod 31. In this way, the clamping block 33 moves linearly along with the convex block 34 until the clamping block 33 abuts against the outer wall of the cabinet. An anti-slip rubber pad is provided on one side of the clamping block 33 to increase the friction force between it and the outer wall of the cabinet. In this way, the clamping block 33 and the first detection plate 2 can apply a clamping force to the cabinet, so as to fix the whole device on the cabinet for subsequent test operations.

[0061] As Figure 2 shown, in this embodiment, the cross-section of the column 1 is rectangular, the column 1 is a hollow structure, and a magnet block vertically distributed is embedded in the back surface of the column 1.

[0062] When the clamping block 33 and the first detection plate 2 clamp the cabinet, the back surface of the column 1 will abut against the cabinet at this time. In this way, a magnetic force will be generated between the magnet block on the column 1 and the cabinet, and the magnetic force and the clamping force can ensure the fixing effect of the device.

[0063] As Figure 5-6 shown, in this embodiment, the first functional component 4 and the second functional component 5 have the same structure, and both include a movable frame 6. A vertical plate 7 is integrally formed by injection molding between the inner walls at the top and bottom of the movable frame 6. A horizontal plate 8 is integrally formed by injection molding between the side wall of the movable frame 6 and the vertical plate 7. A baffle 27 is fixedly bonded to one side of the movable frame 6 and the vertical plate 7. Two cavity grooves are formed by enclosing between the vertical plate 7, the horizontal plate 8 and the inner wall of the movable frame 6. A fixed functional panel 9 and a movable functional panel 10 are arranged in the cavity grooves. Fixing frames 11 are sleeved on the movable functional panel 10 relative to the fixed functional panel 9, and the fixing frames 11 on the fixed functional panel 9 and the movable functional panel 10 are hinged to each other.

[0064] After the first detection plate 2 and the second detection plate 3 are removed, the first functional component 4 and the second functional component 5 can be unfolded at this time, which can be completed by rotating the movable frame 6. In this way, the fixed functional panel 9 and the movable functional panel 10 on the movable frame 6 can be shown. At the same time, by rotating the movable functional panel 10 by 90°, the fixed functional panel 9 and the movable functional panel 10 can be operated simultaneously. There are multiple fixed functional panels 9 and movable functional panels 10, and each corresponds to a different detection module, such as peak detection, RMS detection, and power detection modules, etc.

[0065] The setting of the baffle 27 plays a role in protecting the fixed functional panel 9 and the movable functional panel 10. At the same time, when the first functional component 4 and the second functional component 5 are unfolded, the second conductive contact 13 and the first conductive contact 12 can be blocked to avoid accidental contact.

[0066] As Figure 7-8 shown, in this embodiment, the number of vertical plates 7 is two. A through groove 14 is formed between the two vertical plates 7. A conductive metal strip 16 is arranged in the through groove 14. Grooves 15 are formed in the inner walls of the movable frames 6 on one side of the vertical plates 7. The top and bottom ends of the conductive metal strip 16 are embedded in the grooves 15. An upper conductive cylinder 17 and a lower conductive cylinder 18 are respectively welded to the top and bottom ends of the conductive metal strip 16. Axial holes for the upper conductive cylinder 17 and the lower conductive cylinder 18 to penetrate are formed at the top and bottom ends of the column 1. The upper conductive cylinder 17 and the lower conductive cylinder 18 are connected to the axial holes by bearings.

[0067] The upper conductive cylinder 17 and the lower conductive cylinder 18 are rotatable structures on the column 1 through the axial holes. Furthermore, the conductive metal strip 16 can also rotate freely through the upper conductive cylinder 17 and the lower conductive cylinder 18. The conductive metal strip 16, the vertical plates 7 and the grooves 15 are bonded by insulating glue. In this way, the conductive metal strip 16 can drive the movable frame 6 to rotate, so that the first functional component 4 and the second functional component 5 can rotate and merge or unfold.

[0068] As Figure 3 , Figure 6 , Figure 7 and Figure 8 shown, in this embodiment, a lithium battery 19 is built into the column 1. A conductive component electrically connected to the lithium battery 19 is built into the lithium battery 19. The conductive component is used to supply power to the first detection board 2, the second detection board 3, the first functional component 4 and the second functional component 5. The conductive component includes a first conductive column 20, a second conductive column 21, a third conductive column 22 and a fourth conductive column 23. Third conductive contacts 24 are respectively welded to the ends of the first conductive column 20, the second conductive column 21, the third conductive column 22 and the fourth conductive column 23. Through holes for the third conductive contacts 24 to penetrate are formed in the side wall of the column 1. The bottom ends of the first conductive column 20 and the fourth conductive column 23 are respectively docked with the positive and negative electrodes of the lithium battery 19.

[0069] A group of fourth conductive contacts 25 matching the third conductive contacts 24 are arranged on both the first detection board 2 and the second detection board 3. The internal signal detection module in the first detection board 2 and the external signal detection module in the second detection board 3 are both electrically connected to the third conductive contacts 24.

[0070] The top ends of the second conductive column 21 and the third conductive column 22 respectively extend into the two upper conductive cylinders 17 and are in contact with the inner walls of the upper conductive cylinders 17. A "U"-shaped fifth conductive column 26 is fixedly arranged on the inner wall of the bottom end of the column 1. The two ends of the fifth conductive column 26 respectively extend into the two lower conductive cylinders 18 and are in contact with the inner walls of the lower conductive cylinders 18.

[0071] The fixing frame 11 on the fixed function panel 9 is fixed within the movable frame 6. The first conductive contact 12 and the second conductive contact 13 are respectively arranged on the fixed function panel 9 and the movable function panel 10. Both the first conductive contact 12 and the second conductive contact 13 pass through the fixing frame 11, and the first conductive contact 12 is in contact with the conductive metal strip 16.

[0072] After the first detection plate 2 and the second detection plate 3 slide, at this time, the fourth conductive contact 25 on both of them contacts the third conductive contact 24. Then, the current can flow through the first detection plate 2 along the first conductive column 20 and flow to the second conductive column 21. The current on the second conductive column 21 can flow through the upper conductive cylinder 17 to the conductive metal strip 16 on the first functional component 4, and then flow through the lower conductive cylinder 18 and the fifth conductive column 26 to the conductive metal strip 16 on the second functional component 5 of the first functional component 4, and finally flow through the upper conductive cylinder 17 to the third conductive column 22.

[0073] The current on the third conductive column 22 can flow through the second detection plate 3 and flow to the fourth conductive column 23, thus forming a loop, enabling the first detection plate 2 and the second detection plate 3 to be connected to the circuit and operate.

[0074] After the movable function panel 10 rotates 90°, the second conductive contact 13 on the movable function panel 10 can contact the first conductive contact 12. Since the first conductive contact 12 is in contact with the conductive metal strip 16 and connected to the circuit, in this way, the second conductive contact 13 can indirectly contact the conductive metal strip 16 and be connected to the circuit through the first conductive contact 12. Then, the fixed function panel 9 and the movable function panel 10 can be connected to the circuit and operate.

[0075] After the first detection plate 2 and the second detection plate 3 slide back to their original positions, since the first conductive column 20 and the second conductive column 21 are disconnected, and the third conductive column 22 and the fourth conductive column 23 are disconnected, the entire circuit is disconnected.

[0076] The fourth conductive contact 25 on the second detection plate 3 is in the shape of a long strip. In this way, when the second detection plate 3 is in different positions, the fourth conductive contact 25 on it can still contact the third conductive contact 24. The different moving distances of the second detection plate 3 determine the moving range of the clamping block 33. In this way, the clamping block 33 can clamp cabinets of different thicknesses.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium.
