Description

Technical Field

[0001] This utility model relates to the field of communication testing equipment, and in particular to a portable tri-frequency combiner tester. Background Technology

[0002] In the field of communication network construction and maintenance, tri-band combiner testers, as key signal detection equipment, are widely used in scenarios such as multi-band signal synthesis, transmission quality analysis, and fault diagnosis. With the deep coverage of 5G networks and the integrated application of multi-band communication systems, higher requirements are placed on the portability, flexibility of use, and protection performance of tri-band combiner testers. Currently, the mainstream tri-band combiner testers in the industry still have shortcomings in practical applications. Firstly, in terms of carrying and transportation, existing testers lack integrated protective structures. To avoid damage from bumps and knocks, they usually need to be stored in a special protective case. When using them, the protective case must be opened first to take out the tester. After completing the testing work, the equipment must be cleaned, organized, and put back into the protective case. The entire process of taking out and putting back the tester is cumbersome. Especially in mobile operation scenarios such as outdoor base station inspection and temporary site debugging, the frequent opening and packing not only consumes extra time, but may also increase the burden on staff due to the inconvenience of carrying the protective case, making it difficult to meet the needs of efficient mobile operations. Secondly, regarding the adaptation of the usage angle, existing testing instruments generally adopt a fixed structure design, which requires them to be placed horizontally on the workbench during use. However, the height of the workbench varies greatly in the actual working environment, and the operating postures of the staff are also different. The fixed horizontal placement angle cannot be adjusted according to actual needs. This problem directly leads to the staff having to frequently adjust their body posture to adapt to the fixed viewing angle when observing the data on the testing instrument display. Long-term operation can easily cause fatigue, especially in long-term continuous testing operations, where the negative impact of this problem is more prominent.

[0003] Therefore, it is necessary to provide a new portable three-frequency combiner tester to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a portable three-frequency combiner tester.

[0005] The portable three-frequency combiner tester provided by this utility model includes: a tester body, a protective plate, a mounting base, and an adjustment component. A display is installed on the top of the tester body and a handle for lifting is installed at the end. The top of the tester body is symmetrically provided with protective plates for protecting the display, and anti-slip strips are installed on the side of the two protective plates that are far apart from each other. A mounting base is installed at the end of the tester body that is far away from the handle. A drive component is installed between the protective plate and the mounting base. The adjustment component is used to fix the angle between the protective plate and the tester body.

[0006] Preferably, one of the two protective plates has symmetrically formed limiting holes on one side, and the other has a mounting groove corresponding to the limiting holes on one side. A spring is symmetrically fixed to the inner wall of the mounting groove, and a limiting rod is fixedly connected to the other end of each spring. The two limiting rods are fixedly connected by a connecting rod. A push plate is fixedly connected to the middle of the connecting rod extending out of the outer wall of the protective plate. In the initial state, the limiting rod is placed inside the corresponding limiting hole.

[0007] Preferably, the adjustment component includes: a chuck, a locking block, and a second spring. A rotating rod is rotatably connected inside the mounting base. A chuck is symmetrically fixed to the outer wall of the rotating rod. The side wall of the chuck has equidistant locking slots. The end of the tester body near the mounting base has symmetrical mating slots. A second spring is fixedly connected inside each mating slot. A locking block is fixedly connected to the other end of each second spring. The locking block is placed inside the corresponding mating slot and is slidably connected to its inner wall. The end of the locking block away from the second spring is engaged with at least one locking slot on the side wall of the chuck.

[0008] Preferably, an extension rod is fixedly connected to the bottom of the end of the protective plate near the mounting base, and the extension rod is perpendicular to the protective plate. An arc-shaped rod is fixedly connected to the bottom of both ends of the rotating rod, and the other end of the arc-shaped rod is rotatably connected to the bottom of the corresponding extension rod, with a maximum rotation angle of 90 degrees.

[0009] Preferably, each of the two protective plates is connected to a sleeve via a ball head on the side away from each other. A telescopic rod is slidably connected inside the sleeve, and damping is provided between the telescopic rod and the sleeve. The bottom end of the telescopic rod is connected to the side wall of the tester body via a ball head.

[0010] Preferably, both sleeves are parallel to the corresponding extension rods, and in the initial state, the distance between the sleeves and the telescopic rods is equal to the length of the extension rods.

[0011] Compared with related technologies, the portable three-frequency combiner tester provided by this utility model has the following advantages: With symmetrically arranged protective plates at the top, the device can be directly snapped onto and covered when stored, forming an integrated protective structure without the need for a separate protective case. Users can carry the device directly using the end handle, eliminating the cumbersome process of opening and taking out traditional equipment. This is especially suitable for mobile scenarios such as outdoor base station inspection and temporary site debugging, significantly improving work efficiency. By adjusting the components in conjunction with the sleeve and telescopic rod, the tester body can be tilted and fixed at multiple angles. Users can freely adjust the display viewing angle according to the workbench height and operating posture, avoiding frequent body adjustments caused by fixed angles, reducing neck and eye fatigue, and is especially suitable for long-term continuous testing operations. The mechanical locking of the locking block and chuck slot, combined with the damping structure of the telescopic rod and sleeve, ensures that the adjusted angle is stable and reliable, and can maintain the viewing angle even in environments with slight vibration, ensuring the accuracy of data reading. When stowed, the protective plate tightly wraps around the monitor through precise engagement between the limiting rod and the limiting hole, effectively preventing bumps and dust intrusion during transportation and carrying. When unfolded, the protective plate serves as a lateral support structure, enhancing the overall stability of the device and reducing the risk of accidental tipping during use.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1 to 7 A portable three-frequency combining tester is disclosed. The portable three-frequency combining tester includes: a tester body 1, a protective plate 4, a mounting base 5, and an adjustment component. A display 2 is mounted on the top of the tester body 1, and a handle 3 for lifting is mounted on the end. The top of the tester body 1 is symmetrically provided with protective plates 4 for protecting the display 2, and anti-slip strips 18 are installed on the side of the two protective plates 4 that are far apart from each other. A mounting base 5 is installed on the end of the tester body 1 that is far away from the handle 3. A drive component is installed between the protective plates 4 and the mounting base 5. The adjustment component is used to fix the angle between the protective plates 4 and the tester body 1. A limiting hole 6 is symmetrically opened inside one side of one of the two protective plates 4, and a mounting groove corresponding to the limiting hole 6 is opened inside the other side. A spring 7 is symmetrically fixedly connected to the inner wall of the mounting groove. A limiting rod 8 is fixedly connected to the other end of each spring 7. The two limiting rods 8 are fixedly connected by a connecting rod. A push plate 9 is fixedly connected to the middle of the connecting rod extending out of the outer wall of the protective plate 4. In the initial state, the limiting rod 8 is placed inside the corresponding limiting hole 6.

[0017] It should be noted that the anti-slip strips 18 installed on the opposite sides of the protective plates 4 can increase the contact friction with the workbench when the support is unfolded, thus preventing slippage.

[0018] Please see Figures 3 to 7 The adjustment assembly includes a chuck 10, a locking block 11, and a second spring 12. A rotating rod 13 is rotatably connected inside the mounting base 5. The chuck 10 is symmetrically fixed to the outer wall of the rotating rod 13. The side wall of the chuck 10 has equidistant locking slots. The tester body 1 has symmetrically formed mating slots near the mounting base 5. A second spring 12 is fixedly connected inside each mating slot. The other end of each second spring 12 is fixedly connected to a locking block 11. The locking block 11 is placed inside the corresponding mating slot and slidably connected to its inner wall. The end of the locking block 11 away from the second spring 12 engages with at least one locking slot on the side wall of the chuck 10. An extension rod 14 is fixedly connected to the bottom of the protective plate 4 near the mounting base 5. Furthermore, the extension rod 14 is perpendicular to the protective plate 4, and the bottom of both ends of the rotating rod 13 are fixedly connected to the arc rod 15. The other end of the arc rod 15 is rotatably connected to the bottom of the corresponding extension rod 14, and the maximum rotation angle is 90 degrees. The two protective plates 4 are connected to the sleeves 16 through ball heads on the opposite sides. The sleeves 16 are slidably connected to the telescopic rods 17, and there is damping between the telescopic rods 17 and the sleeves 16. The bottom end of the telescopic rods 17 is connected to the side wall of the tester body 1 through ball heads. The two sleeves 16 are parallel to the corresponding extension rods 14, and in the initial state, the distance between the sleeves 16 and the telescopic rods 17 is equal to the length of the extension rods 14.

[0019] It should be noted that the ball head sleeve connected to the bottom ball head of the telescopic rod 17 is rotatably connected to the side wall of the tester body 1, which is used to adapt to the adjustment of the angle between the protective plate 4 and the tester body 1.

[0020] The working principle of the portable three-frequency combiner tester provided by this utility model is as follows: In the initial state, the two protective plates 4 are tightly fastened to the top of the tester body 1 and locked by a limiting structure to protect the top display 2. When the tester needs to be used, the locking state of the protective plates 4 must first be released. The specific steps are as follows: Pushing the push plate 9 on the outer wall of one of the protective plates 4, the push plate 9 is fixedly connected to the connecting rod. The pushing force will directly drive the connecting rod to move horizontally along the inside of the protective plate 4. The two ends of the connecting rod are fixed to two limiting rods 8 respectively. When the connecting rod moves, it will simultaneously drive the two limiting rods 8 to slide into the mounting groove. At this time, the limiting rod 8 will compress the spring 7 fixed on the inner wall of the mounting groove, so that the spring 7 is in an energy storage state. As the push plate 9 continues to push, the limiting rod 8 gradually exits from the limiting hole 6 opened on the side wall of the other protective plate 4. When the limiting rod 8 completely disengages from the limiting hole 6, the locking state of the two protective plates 4 is officially released, and they are ready to rotate to both sides. After the protective plate 4 is unlocked, it needs to be rotated to both sides of the tester body 1 to form a support base for subsequent angle adjustment. The specific process is as follows: rotate the two protective plates 4 to both sides of the tester body 1; since an extension rod 14 is fixed to the bottom of the end of the protective plate 4 near the mounting base 5, and the extension rod 14 is perpendicular to the protective plate 4, and the bottom of the extension rod 14 is rotatably connected to the ends of the arc-shaped rods 15 fixed at both ends of the rotating rod 13, when the protective plate 4 rotates, the extension rod 14 will rotate synchronously around the rotatable connection point with the arc-shaped rod 15; the arc-shaped rod 15 is fixed to the rotating rod 13, and the design limits the maximum rotation angle to 90 degrees. Therefore, the protective plate 4 always moves along a fixed trajectory during rotation, and there will be no excessive rotation. When the protective plate 4 rotates to be perpendicular to the top of the tester body 1, it stops rotating. At this time, the protective plate 4 is stably in a lateral support state. During the rotation of the protective plate 4, the sleeve 16 connected to the opposite side by a ball head will rotate synchronously with the protective plate 4. Since the sleeve 16 has a telescopic rod 17 slidably connected inside, and the bottom end of the telescopic rod 17 is connected to the side wall of the tester body 1 through a ball head, when the sleeve 16 rotates, it will drive the telescopic rod 17 to rotate synchronously with the ball head connection point on the side wall of the tester body 1 as the fulcrum, which prepares the structure for the subsequent angle adjustment of the tester body 1. After the protective plate 4 is unfolded, the tilt angle of the tester body 1 can be adjusted according to the actual working scenario to clearly observe the data on the display 2. The specific adjustment process is as follows: one hand holds down the unfolded protective plate 4 on one side to fix it and prevent the protective plate 4 from shifting during the adjustment process; the other hand pulls the handle 3 at the end of the tester body 1 and slowly lifts the tester body 1 upward, so that the tester body 1 rotates upward around the rotating rod 13 connected inside the mounting base 5; chucks 10 are symmetrically fixed on the outer wall of the rotating rod 13, and slots are equidistantly opened on the side wall of the chuck 10; when the tester body 1 rotates around the rotating rod 13, the rotating rod 13 will drive the chuck 10 to rotate synchronously; during the rotation of the chuck 10, the slot on its side wall will contact and squeeze the locking block 11 in the mating groove at the end of the tester body 1 near the mounting base 5, forcing the locking block 11 to slide into the mating groove, and at the same time compressing the spring 12 fixed in the mating groove, so that the spring 12 enters the energy storage state. As the tester body 1 continues to rotate, when the adjacent slot on the side wall of the chuck 10 rotates to align with the locking block 11, the second spring 12 will immediately release its stored elastic force, pushing the locking block 11 to move towards the slot and re-engage with it, thus initially fixing the current angle of the tester body 1. During this process, the telescopic rod 17 connected to the side wall of the tester body 1 via the ball joint will slide along the inside of the sleeve 16. Due to the damping between the telescopic rod 17 and the sleeve 16, the rotation of the tester body 1 is ensured to be smooth. The user can gradually adjust the tilt angle of the tester body 1 according to the actual situation until the optimal viewing angle is achieved. After the angle adjustment is completed, the elastic force of the second spring 12 causes the locking block 11 to stably engage with the corresponding slot of the chuck 10. At the same time, the damping between the sleeve 16 and the telescopic rod 17 further enhances the angle locking effect. The dual fixing mechanism ensures that the tester body 1 remains stable at the adjusted angle and will not shift on its own. After the test is completed, the tester needs to be stored and reset to its protective state. The specific process is as follows: hold the protective plate 4 with one hand, and hold the handle 3 with the other hand and slowly press down on the tester body 1, so that the tester body 1 rotates down around the rotating rod 13 to reset. During this process, the chuck 10 rotates in the opposite direction with the rotating rod 13, and the chuck groove squeezes the chuck block 11 again, so that the chuck block 11 compresses the spring 12 and retracts into the mating groove until the tester body 1 is completely flat and parallel to the protective plate 4. At the same time, the telescopic rod 17 will slide in the opposite direction inside the sleeve 16 and gradually retract into the sleeve 16 to restore its initial length. Next, rotate the protective plate 4 with the limiting hole 6 90 degrees toward the middle of the tester body 1, so that it is close to the top of the tester body 1; then rotate the protective plate 4 with the limiting rod 8: push the push plate 9 on the outer wall of the protective plate 4, and drive the limiting rod 8 to slide into the mounting groove through the connecting rod and compress the spring 7 until the limiting rod 8 is completely retracted into the mounting groove; then rotate the protective plate 4 90 degrees toward the middle, and when it is aligned with the protective plate 4 with the limiting hole 6, release the push plate 9; at this time, the spring 7 releases the stored elastic force, pushes the limiting rod 8 to move toward the limiting hole 6, and finally makes the limiting rod 8 insert into the limiting hole 6, so as to realize the re-locking of the two protective plates 4; After the protective plate 4 is fastened, it tightly covers the top of the tester body 1, which can effectively prevent external collisions from damaging the top-mounted display 2 during movement; at this time, the user can lift the device through the handle 3 at the end of the tester body 1 to complete the entire storage process, making it convenient to carry and transport the device.
