Description

Technical Field

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

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

[0003] There are currently a variety of signal detection devices on the market for communication signal detection in different scenarios. Among them, portable 5G signal detection devices are widely used in field testing due to their lightness and ease of carrying. For example, CN117353846B in the prior art discloses a portable 5G communication detection device, which reduces the volume of the overall device by designing all functional panels to be detachable and stacking them in a special storage box. This design does improve the portability of the device and can effectively reduce the space occupied by transportation and storage. However, in actual use, this structural design still has many limitations.

[0004] First, when using this detection device, the operator needs to frequently take the function panel out of the storage box and put it back after the detection is completed. This operation process is relatively cumbersome, especially in scenarios that require rapid detection and frequent use, the operation efficiency is low, and it is easy to cause delays in detection work. In addition, the connecting parts of the function panel are usually exposed to the outside, and this exposed design increases the risk of the parts being affected by the external environment. Factors such as water vapor erosion and foreign body impact may cause circuit damage, unstable signal transmission, and even equipment failure, seriously affecting the reliability and safety of detection. Secondly, in actual applications, signal detection equipment usually needs to be fixed on a communication cabinet or other mounting surface to ensure stability and ease of operation. Existing solutions usually use magnets to fix the equipment on the cabinet door, but due to the large overall weight of the equipment, relying solely on magnetic force is not enough to provide sufficient fixing strength. Especially in an environment with external force or vibration, the equipment may slip off the communication cabinet, which not only affects the detection work, but also may cause damage to the equipment, posing obvious safety hazards. 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 art.

[0006] Therefore, the object of the present invention is to provide a communication signal testing device, including 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 arranged on the back of the column, a clamping block is attached to the back of the column, support seats are bolted on the groove walls on both sides of the first groove, and a group of guide rods are welded and connected between the two support seats.

[0008] The clamping block is protruded toward one side of the column to form a convex block, and the guide rod passes through the convex block and is slidably connected with 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 between the inner walls of the top and bottom ends of the movable frame, a horizontal plate is integrally formed between the side walls 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 cavities are formed 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 cavities. The movable function panel is provided with a fixed frame relative to the fixed function panel. The fixed frames on the fixed function panel and the movable function panel are hinged.

[0011] The column has a built-in lithium battery, the lithium battery has a built-in conductive component electrically connected to the lithium battery, and the conductive component is used to supply power to the first detection board, the second detection board, the first functional component and the second functional component.

[0012] The first detection board has an internal signal detection module built in, and the second detection board has an external signal detection module built in.

[0013] The columns, movable frames, vertical plates, horizontal plates and fixed frames are all made of insulating materials, such as phenolic plastic. This can improve the insulation of the equipment during operation, avoid electric shock, and provide high safety. At the same time, while ensuring the strength, the overall weight can be reduced so that the equipment 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, such as copper, which can improve the circuit signal transmission rate.

[0015] As the 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] In a communication signal testing device as described above, a group of fourth conductive contacts matching with the third conductive contacts are provided on the first detection board and the second detection board, and the internal signal detection module in the first detection board and the external signal detection module in the second detection board are both electrically connected to the third conductive contacts.

[0027] Through the above technical solution, when the first detection plate and the second detection plate are removed, the circuit can be connected through the fourth conductive contact and the third conductive contact, and when reset, the circuit can be disconnected again.

[0028] In the communication signal testing device as described above, there are two vertical plates, a through slot is formed between the two vertical plates, and a conductive metal strip is arranged in the through slot.

[0029] The inner wall of the movable frame on one side of the vertical plate is provided with grooves, the top and bottom ends of the conductive metal strip are embedded in the grooves, and the top and bottom ends of the conductive metal strip are respectively welded to an upper conductive cylinder and a lower conductive cylinder.

[0030] Through the above technical solution, insulating materials, such as insulating ceramic coatings, are attached to the outside of the conductive metal strip. When the movable frame is rotated and unfolded, the exposed parts of the conductive metal strip are covered with insulating materials, thus avoiding accidental touch and electric shock, and further improving the overall safety.

[0031] In a communication signal testing device as described above, the top and bottom ends of the column are provided with axial holes for the upper conductive tube and the lower conductive tube to pass through, the upper conductive tube and the lower conductive tube are connected to the axial holes by bearings, and the top ends of the second conductive column and the third conductive column are respectively extended into the two upper conductive tubes and fit against the inner walls of the upper conductive tubes.

[0032] Through the above technical solution, the upper conductive tube and the lower conductive tube are a rotating structure on the column, so that the movable frame can rotate freely, and the first functional component and the second functional component can be rotated, combined and unfolded.

[0033] In the communication signal testing device as described above, a "U"-shaped fifth conductive column is fixedly provided on the inner wall of the bottom end of the column, and two ends of the fifth conductive column respectively extend into the two lower conductive cylinders and fit 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 conductive, so that the first functional component and the second functional component can be in the same circuit, and the structure is reasonable.

[0035] In a communication signal testing device as described above, the fixed frame on the fixed function panel is fixed in the movable frame, and the fixed function panel and the movable function panel are respectively provided with a first conductive contact and a second conductive contact, the first conductive contact and the second conductive contact both pass through the fixed frame, and the first conductive contact is in contact with the conductive metal strip.

[0036] Through the above technical solution, the fixed function panel is a fixed structure in the fixed frame. When the movable function panel is rotated 90°, the fixed function panel and the movable function panel form a right angle structure, so that operations can be performed on the fixed function panel and the movable function panel at the same time.

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

[0038] (1) Multiple fixing mechanisms significantly improve the stability and safety of the equipment: The present invention adopts a double fixing scheme, combining clamping blocks and magnet blocks to ensure the firmness of the equipment. When the second detection plate and the first detection plate slide to the predetermined position, the clamping block will move synchronously with the movement of the detection plate, and use the clamping force to tightly adhere to and firmly clamp the communication cabinet to prevent sliding or falling off. In addition, the magnet block embedded on the back of the device generates a magnetic force with the cabinet to provide additional fixing force. This design can remain stable when dealing with equipment vibration or external force impact, and is particularly suitable for communication signal testing in harsh environments, greatly improving the safety and reliability of operations.

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

[0040] (3) Concealed conductive component design to enhance insulation and equipment safety: The conductive components of the device are completely built into the pillars and movable frames, and all circuit connection parts are encapsulated with insulating materials. When the device is not in use or in storage, the conductive components will not be exposed to the outside, preventing electrical failures caused by humid environments or external physical damage. In addition, the insulation design effectively isolates the user from direct contact with the circuit system, reducing the risk of electric shock and ensuring safe operation. This safety optimization enables the device to operate stably in various complex environments and meet high standards of electrical safety requirements. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

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

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

[0053] like Figure 1-2 As shown, a communication signal testing device comprises 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 board 2 has an internal signal detection module built in, and the second detection board 3 has an external signal detection module built in.

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

[0056] like Figure 3-4 As shown, in this embodiment, a group of sliding grooves 38 are opened on the opposite sides of the first detection plate 2 and the second detection plate 3, and T-shaped sliding bars 37 are protruded from the walls of both sides of the column 1, and the sliding bars 37 are embedded in the sliding grooves 38.

[0057] Since the sliding bar 37 is embedded in the sliding groove 38, the first detection plate 2 and the second detection plate 3 can be formed as one body with the column 1. When not in operation, the device as a whole forms a flat square structure, which is small in size and easy to carry. When in operation, the device as a whole can be unfolded by sliding the first detection plate 2 and the second detection plate 3.

[0058] like Figure 3-4 As shown, in this embodiment, two first grooves 28 are provided on the back of the column 1, a clamping block 33 is attached to the back of the column 1, support seats 30 are bolted on the groove walls on both sides of the first groove 28, a group of guide rods 31 are welded and connected between the two support seats 30, the clamping block 33 protrudes toward one side of the column 1 to form a protrusion 34, and the guide rod 31 passes through the protrusion 34 and is slidably connected with the protrusion 34.

[0059] The second detection plate 3 is provided with a second groove 29 on one side facing the first detection plate 2, a rack 36 is bonded to the end of the second groove 29, a screw rod 32 is connected with a bearing between the two support seats 30, the screw rod 32 passes through the protrusion 34 and is threadedly connected to the protrusion 34, one end of the screw rod 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 to a certain range, the rack 36 will contact and mesh with the gear 35, so that the rack 36 will push the gear 35 to rotate, and the screw rod 32 will rotate synchronously with the gear 35 and drive the protrusion 34 to slide along the guide rod 31, so that the clamping block 33 moves in a straight line with the protrusion 34 until the clamping block 33 is tightly against the outer wall of the cabinet. A non-slip rubber pad is provided on one side of the clamping block 33 to increase the friction between the outer wall of the cabinet. In this way, the clamping block 33 can cooperate with the first detection plate 2 to apply a clamping force to the cabinet, so as to fix the equipment as a whole on the cabinet, which is convenient for subsequent testing operations.

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

[0062] When the clamping block 33 cooperates with the first detection plate 2 to clamp the cabinet, the back of the column 1 will be pressed against the cabinet, so that the magnet block on the column 1 will generate magnetic force with the cabinet, and the magnetic force combined with the clamping force can ensure the fixing effect of the equipment.

[0063] like Figure 5-6 As shown, in the present 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 between the inner walls at the top and bottom ends of the movable frame 6, a horizontal plate 8 is integrally formed by injection 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 cavities are formed 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 cavities, the movable functional panel 10 is sleeved with a fixed frame 11 relative to the fixed functional panel 9, and the fixed frames 11 on the fixed functional panel 9 and the movable functional panel 10 are hinged.

[0064] When the first detection board 2 and the second detection board 3 are moved apart, the first functional component 4 and the second functional component 5 can be unfolded by rotating the movable frame 6, so that the fixed function panel 9 and the movable function panel 10 on the movable frame 6 can be displayed, and the movable function panel 10 can be rotated 90° at the same time, so that the fixed function panel 9 and the movable function panel 10 can be operated at the same time. There are multiple fixed function panels 9 and movable function panels 10, each corresponding to a different detection module, such as peak detection, RMS detection and power detection module.

[0065] The baffle 27 protects the fixed functional panel 9 and the movable functional panel 10. 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 shielded to avoid accidental contact.

[0066] like Figure 7-8 As shown, in the present embodiment, there are two vertical plates 7, a through slot 14 is formed between the two vertical plates 7, a conductive metal strip 16 is arranged in the through slot 14, a groove 15 is provided on the inner wall of the movable frame 6 on one side of the vertical plate 7, the top and bottom ends of the conductive metal strip 16 are embedded in the groove 15, the top and bottom ends of the conductive metal strip 16 are respectively welded with an upper conductive tube 17 and a lower conductive tube 18, an axial hole for the upper conductive tube 17 and the lower conductive tube 18 to penetrate is provided at the top and bottom ends of the column 1, and the upper conductive tube 17 and the lower conductive tube 18 are connected to the axial hole by bearings.

[0067] The upper conductive tube 17 and the lower conductive tube 18 are rotatable structures on the column 1 through the axial hole, and the conductive metal strip 16 can also rotate freely through the upper conductive tube 17 and the lower conductive tube 18. The conductive metal strip 16 and the vertical plate 7 and the groove 15 are all bonded by insulating glue, so that 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 be rotated, merged or unfolded.

[0068] like Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the column 1 has a built-in lithium battery 19, and the lithium battery 19 has a built-in conductive component electrically connected to the lithium battery 19, and 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. The ends of the first conductive column 20, the second conductive column 21, the third conductive column 22 and the fourth conductive column 23 are all welded with a third conductive contact 24, and a through hole for the third conductive contact 24 to pass through is opened on the side wall of the column 1, and the bottom ends of the first conductive column 20 and the fourth conductive column 23 are respectively connected to the positive and negative electrodes of the lithium battery 19.

[0069] A group of fourth conductive contacts 25 matching with the third conductive contacts 24 are provided on 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 extend into the two upper conductive cylinders 17 respectively and fit with the inner walls of the upper conductive cylinders 17. A "U"-shaped fifth conductive column 26 is fixedly provided on the inner wall of the bottom end of the column 1. The two ends of the fifth conductive column 26 extend into the two lower conductive cylinders 18 respectively and fit with the inner walls of the lower conductive cylinders 18.

[0071] The fixed frame 11 on the fixed functional panel 9 is fixed in the movable frame 6. The fixed functional panel 9 and the movable functional panel 10 are respectively provided with a first conductive contact 12 and a second conductive contact 13. The first conductive contact 12 and the second conductive contact 13 both pass through the fixed frame 11, and the first conductive contact 12 is in contact with the conductive metal strip 16.

[0072] When the first detection plate 2 and the second detection plate 3 slide, the fourth conductive contact 25 on both of them contacts the third conductive contact 24, and 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 conductive metal strip 16 on the first functional component 4 through the upper conductive tube 17, and then flow through the conductive metal strip 16 on the first functional component 4 and the second functional component 5 through the lower conductive tube 18 and the fifth conductive column 26, and finally flow through the third conductive column 22 through the upper conductive tube 17.

[0073] The current on the third conductive column 22 can flow through the second detection board 3 and flow to the fourth conductive column 23, so that a loop can be formed, so that the first detection board 2 and the second detection board 3 can be connected to the circuit and operate.

[0074] When the movable functional panel 10 rotates 90°, the second conductive contact 13 on the movable functional panel 10 can contact the first conductive contact 12. Since the first conductive contact 12 contacts the conductive metal strip 16 and is connected to the circuit, 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, and then the fixed functional panel 9 and the movable functional panel 10 can be connected to the circuit and operate.

[0075] When the first detection plate 2 and the second detection plate 3 slide back to their original positions, the first conductive pillar 20 and the second conductive pillar 21 are disconnected, and the third conductive pillar 22 and the fourth conductive pillar 23 are disconnected, so that 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, so that when the second detection plate 3 is in different positions, the fourth conductive contact 25 thereon 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, so that cabinets of different thicknesses can be clamped by the clamping block 33.

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.
