DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clarify the technical solutions in the embodiments of the present invention; it is clearly described in detail. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The present invention provides Figures 1 to 8 The foldable portable signal analyzer shown includes a signal analyzer body 1, on which a display screen, operation keys and other structures are provided. The signal analyzer body 1 and its working principle are both common technologies in the prior art and are not described in detail here. Both sides of the shell of the signal analyzer body 1 are fixedly connected to a cylinder 2;

[0037] Considering that the existing signal analyzers lack a protective structure, the display screen and operation keys are prone to dust accumulation and damage by accidental touch when not used for a long time. In order to improve the use efficiency of the signal analyzer, a first ring 7 is rotatably connected to the cylinder 2, and there is a certain damping sense between the first ring 7 and the cylinder 2. When subjected to external force, it can rotate, and after the external force stops, it can maintain its position. A square tube 3 is fixedly connected to the outer ring of the first ring 7, and a sliding column 4 is slidably connected to the inside of the square tube 3, and the sliding column 4 passes through the end of the square tube 3 away from the first ring 7. A first spring 9 is arranged inside the square tube 3, one end of the first spring 9 is fixedly connected to the inner wall of the square tube 3, and the other end of the first spring 9 is fixedly connected to the sliding column 4. A protective box 5 for protecting the display screen and operation keys of the signal analyzer body 1 is fixedly connected between the two sliding columns 4. When not in use, the protective box 5 covers the side of the signal analyzer body 1 where the display screen and operation keys are arranged (refer to Figure 1 ), during the operation of transportation, when the external impact force acts on the protection box 5, it will drive the protection box 5 to move toward the signal analyzer body 1, and the protection box 5 will drive the slide column 4 to be recovered into the square tube 3, and the first spring 9 will contract and perform force unloading and buffering, thereby achieving the effect of protecting the signal analyzer body 1.

[0038] A gas channel 19 is formed through the sliding column 4, and the gas channel 19 is connected to the square tube 3. First air holes 8 are formed through both ends of the protection box 5, and the first air holes 8 are connected to the corresponding gas channels 19. An air bag ring 6 is fixedly connected to the side of the protection box 5 facing the signal analyzer body 1, and the air bag ring 6 is connected to the protection box 5. In order to achieve the connection between the air bag ring 6 and the protection box 5, a second air hole 25 is formed on the side of the protection box 5 close to the signal analyzer body 1, and the protection box 5 is connected to the air bag ring 6 through the second air hole 25.

[0039] The airbag ring 6 is fitted around the side of the signal analyzer body 1 where the display screen and operation keys are provided, and with the cooperation of the protective box 5, the display screen and keys are covered to avoid damage caused by accidental touches, while achieving the effect of sealing, dustproofing and preventing accidental touches.

[0040] Furthermore, when an external impact force acts on the protection box 5, the sliding column 4 is retracted into the square tube 3, so that the gas inside the square tube 3 enters the protection box 5 through the gas channel 19 and the first air hole 8, and enters the airbag ring 6 through the second air hole 25, so that the airbag ring 6 expands and becomes larger to relieve force and buffer, thereby improving the protection effect.

[0041] When specifically set, the airbag ring 6 is in a square shape, and can also be adjusted according to the structure of the signal analyzer body 1 having a display screen and operation keys. The airbag ring 6 is set to match the appearance characteristics of the signal analyzer body 1 and can be adaptively deformed to avoid wear on the outside of the signal analyzer body 1.

[0042] Considering that the signal analyzer is usually placed on a fixed table for use, its use height depends on the height of the fixed table, which is not easy to adjust. In order to improve the convenience of using the signal analyzer, a second ring 14 is rotatably connected to the cylinder 2, and there is a certain damping sense between the second ring 14 and the cylinder 2. When subjected to external force, it can rotate, and after the external force stops, it can keep its position. A support column 15 is fixedly connected to the second ring 14.

[0043] When not in use, the support column 15 and the slide column 4 are folded and recovered at the side of the signal analyzer body 1 (see Figure 1 When the signal analyzer body 1 needs to be used for information analysis and needs to be lifted, the support column 15, the sliding column 4, and the square tube 3 are controlled to be distributed in an inverted V shape to support and lift the signal analyzer body 1 for easy use by operators.

[0044] In addition, during the adjustment process, the height of the signal analyzer body 1 can be adjusted by controlling the angle between the support column 15 and the square tube 3, thereby improving the convenience of using the signal analyzer.

[0045] By arranging structures such as the square tube 3, the sliding column 4, the airbag ring 6 and the support column 15, the effects of closed dust prevention, prevention of accidental touch and buffer protection are achieved, thereby improving the use efficiency of the signal analyzer. At the same time, the signal analyzer body 1 can be supported and raised for the convenience of operators, and the angle between the support column 15 and the square tube 3 can be controlled to adjust the height of the signal analyzer body 1, thereby improving the convenience of using the signal analyzer.

[0046] In order to fix the positions of the first and second circular rings 7 and 14, a pressing sleeve 18 is slidably mounted on the end of the cylinder 2 away from the signal analyzer body 1 for squeezing and positioning the first and second circular rings 7 and 14. When the pressing sleeve 18 moves toward the signal analyzer body 1, it squeezes the first and second circular rings 7 and 14 to achieve positioning. A threaded groove 16 is provided on the side of the cylinder 2 facing away from the signal analyzer body 1, and a bolt 17 is provided inside the threaded groove 16. A circular groove for the bolt 17 to pass through is provided on the pressing sleeve 18.

[0047] During operation, the bolt 17 is rotated to release the restriction on the first ring 7 and the second ring 14, so as to facilitate the rotation of the first ring 7 and the second ring 14; after the adjustment is completed, the bolt 17 is rotated in the opposite direction to squeeze and position the first ring 7 and the second ring 14 through the pressing sleeve 18. In the specific use process, other positioning methods can also be used to position the first ring 7 and the second ring 14.

[0048] To further improve the protection effect, both ends of the protection box 5 close to the signal analyzer body 1 are provided with square grooves 12, and the two square grooves 12 are distributed one by one with the two support columns 15. A slider 13 is slidably penetrated inside the square groove 12, and the slider 13 is abutted with the corresponding support column 15. A cover block 10 is fixedly connected to one end of the slider 13 located inside the protection box 5, and the cover block 10 is matched with the corresponding first air hole 8.

[0049] The second spring 11 is fixedly connected to the side of the shielding block 10 facing away from the slider 13 , and the end of the second spring 11 away from the shielding block 10 is fixedly connected to the inner wall of the protection box 5 . The elastic supporting force of the second spring 11 is greater than the elastic supporting force of the first spring 9 .

[0050] Specifically, during the process of transportation and other operations, when the external impact force acts on the protection box 5, it will drive the protection box 5 to move toward the signal analyzer body 1, and the protection box 5 will drive the sliding column 4 to be retracted into the square tube 3, the first spring 9 will contract and perform the first round of force unloading buffering; because the slider 13 is abutted against the corresponding support column 15, when the protection box 5 moves toward the signal analyzer body 1, the positions of the slider 13 and the cover block 10 remain stationary, the second spring 11 is compressed, and the second round of force unloading buffering is performed; at this time, the cover block 10 is out of contact with the inner wall of the protection box 5, the first air hole 8 is opened, and when the sliding column 4 is retracted into the square tube 3, the gas inside the square tube 3 enters the protection box 5 through the gas channel 19 and the first air hole 8, and enters the airbag ring 6 through the second air hole 25, so that the airbag ring 6 expands and becomes larger, and the third round of force unloading buffering is performed, thereby achieving the effect of protecting the signal analyzer body 1.

[0051] By providing the first spring 9 , the second spring 11 , the airbag ring 6 and other structures, three force unloading buffers can be simultaneously achieved when protecting the signal analyzer body 1 , thereby improving the protection effect of the signal analyzer body 1 .

[0052] After the second spring 11 is fully compressed, the protective box 5 will not continue to move in the direction of the signal analyzer body 1 due to the abutment and cooperation between the slider 13 and the corresponding support column 15, thereby avoiding squeezing the display screen and buttons.

[0053] After the external impact force disappears, the protection box 5, the sliding column 4 and other structures are restored under the action of the restoring elastic force of the first spring 9 and the second spring 11. When the sliding column 4 is restored and extended from the inside of the square tube 3, the gas inside the airbag ring 6 flows back to the inside of the square tube 3 through the second air hole 25, the protection box 5, the first air hole 8 and the gas channel 19, and then the cover block 10 contacts the inner wall of the protection box 5, and the first air hole 8 is closed, which is convenient for subsequent protection.

[0054] Further, when the signal analyzer body 1 needs to be used for information analysis and needs to be raised, the bolt 17 is rotated to release the restrictions on the first ring 7 and the second ring 14; the protection box 5 is pushed downward, and the support column 15 rotates synchronously due to the abutment of the slider 13 and the corresponding support column 15, and then the support column 15 is separated from the slide column 4 and distributed in an inverted V shape (refer to Figure 7 ), at the moment when the support column 15 is separated from the sliding column 4, the sliding block 13 is retracted into the protective box 5 under the extrusion force of the end of the support column 15. After the support column 15 and the sliding block 13 are offset, the sliding block 13 is quickly reset under the restoring elastic force of the second spring 11.

[0055] Then, the bolt 17 is rotated in the opposite direction, and the first and second circular rings 7 and 14 are squeezed and positioned by the pressing sleeve 18. The support column 15, the sliding column 4 and the square tube 3 are distributed in an inverted V shape, and the signal analyzer body 1 is supported and raised for the convenience of the operator.

[0056] When it is necessary to make the display screen and one end of the button of the signal analyzer body 1 tilt upward for the convenience of the operator, the operator can press the slider 13, and the slider 13 is retracted into the protective box 5, so that the first air hole 8 is opened, and the operator controls the slide column 4 to be retracted into the square tube 3, so that the gas inside the square tube 3 enters the protective box 5 through the gas channel 19 and the first air hole 8, and enters the air bag ring 6 through the second air hole 25, so that the air bag ring 6 expands and becomes larger; after the adjustment is completed, the slider 13 is released, and under the action of the reset elastic force of the second spring 11, the slider 13 is quickly reset, the cover block 10 closes the first air hole 8, and the elastic supporting force of the second spring 11 is greater than the elastic supporting force of the first spring 9, the first air hole 8 remains closed, and the air pressure between the square tube 3 and the gas channel 19 is stable, so that the slide column 4 will not rebound, so that the display screen and one end of the button of the signal analyzer body 1 tilt upward, and its inclination angle is adjusted to facilitate the operator's use.

[0057] By pressing the slider 13 and controlling the slide post 4 to slide inside the square tube 3, the tilt angle of the signal analyzer body 1 is adjusted to facilitate use by operators.

[0058] Considering that when used outdoors, direct sunlight may affect the operator's viewing of the display screen, a baffle 24 is provided on the side of the protection box 5 facing away from the signal analyzer body 1. The baffle 24 may be made of, but not limited to, ABS alloy material, which not only has a good light-shielding effect, but also has high use strength. To facilitate the adjustment of the angle of the baffle 24, a connecting component is provided between the baffle 24 and the protection box 5 to facilitate the adjustment of the angle of the baffle 24. The connecting component is provided in two groups, and the two groups of connecting components are respectively distributed on both sides of the baffle 24.

[0059] In a specific configuration, the connecting assembly includes a first round block 20, a first rotating plate 21, a second rotating plate 22, a second round block 23 and a third round block 26. The first round block 20 is fixedly connected to the side wall of the protective box 5, the first rotating plate 21 is rotatably connected to the first round block 20, the end of the first rotating plate 21 away from the first round block 20 is rotatably connected to the third round block 26, the second rotating plate 22 is rotatably connected to the third round block 26, the second round block 23 is rotatably connected to the end of the second rotating plate 22 away from the third round block 26, and the second round block 23 is fixedly connected to the side wall of the baffle 24.

[0060] There is a certain damping feeling between the first round block 20 and the first rotating plate 21, between the first rotating plate 21 and the third round block 26, between the second rotating plate 22 and the third round block 26, and between the second round block 23 and the second rotating plate 22. When subjected to external force, they can rotate, and after the external force stops, they can maintain their position, which is convenient for adjusting the position of the baffle 24.

[0061] Specifically, the protective box 5 and other structures are moved upward to adjust Figure 8 Then, with the cooperation of the connecting components, the baffle 24 is flipped so that the baffle 24 covers a suitable position above the display screen to achieve a light shielding effect and improve the practicality of the signal analyzer.

[0062] In addition, since the baffle 24 is located outside the protection box 5, the protection box 5 can be protected. After being worn out due to long-term use, only the baffle 24 needs to be replaced, thereby reducing the cost of equipment use.

[0063] Working principle: When not in use, fold and recycle Figure 1 At this time, the U-shaped airbag ring 6 is attached to the periphery of the signal analyzer body 1 where the display screen and operation keys are provided, and with the cooperation of the protective box 5, the display screen and keys are covered to avoid damage caused by accidental touch, and at the same time, the effect of sealing, dustproofing and preventing accidental touch is achieved.

[0064] In addition, since the airbag ring 6 is in a square shape and can be adaptively deformed, wear on the exterior of the signal analyzer body 1 is avoided.

[0065] During the process of transportation and other operations, when the external impact force acts on the baffle 24, it will drive the protection box 5 to move toward the signal analyzer body 1, and the protection box 5 will drive the slide column 4 to be retracted into the square tube 3, the first spring 9 will contract and perform the first round of force unloading buffering; because the slider 13 is in abutment with the corresponding support column 15, when the protection box 5 moves toward the signal analyzer body 1, the positions of the slider 13 and the cover block 10 remain stationary, the second spring 11 is compressed, and the second round of force unloading buffering is performed; at this time, the cover block 10 is out of contact with the inner wall of the protection box 5, the first air hole 8 is opened, and when the slide column 4 is retracted into the square tube 3, the gas inside the square tube 3 enters the protection box 5 through the gas channel 19 and the first air hole 8, and enters the airbag ring 6 through the second air hole 25, so that the airbag ring 6 expands and becomes larger, and the third round of force unloading buffering is performed, thereby achieving the effect of protecting the signal analyzer body 1.

[0066] After the second spring 11 is fully compressed, the protective box 5 will not continue to move in the direction of the signal analyzer body 1 due to the abutment and cooperation between the slider 13 and the corresponding support column 15, thereby avoiding squeezing the display screen and buttons.

[0067] After the external impact force disappears, the protection box 5, the sliding column 4 and other structures are restored under the action of the restoring elastic force of the first spring 9 and the second spring 11. When the sliding column 4 is restored and extended from the inside of the square tube 3, the gas inside the airbag ring 6 flows back to the inside of the square tube 3 through the second air hole 25, the protection box 5, the first air hole 8 and the gas channel 19, and then the cover block 10 contacts the inner wall of the protection box 5, and the first air hole 8 is closed, which is convenient for subsequent protection.

[0068] When the signal analyzer body 1 needs to be used for information analysis and needs to be raised, the bolt 17 is rotated to release the restrictions on the first ring 7 and the second ring 14; the protection box 5 is pushed downward, and the support column 15 rotates synchronously due to the abutment of the slider 13 and the corresponding support column 15, and then the support column 15 is separated from the slide column 4 and distributed in an inverted V shape (refer to Figure 7 ), at the moment when the support column 15 is separated from the sliding column 4, the slider 13 drives the shielding block 10 to move toward the baffle 24 under the extrusion force of the end of the support column 15. After the support column 15 and the slider 13 are offset, the slider 13 is quickly reset under the reset elastic force of the second spring 11.

[0069] Then, the bolt 17 is rotated in the opposite direction, and the first and second circular rings 7 and 14 are squeezed and positioned by the pressing sleeve 18. The support column 15, the sliding column 4 and the square tube 3 are distributed in an inverted V shape, and the signal analyzer body 1 is supported and raised for the convenience of the operator.

[0070] At the same time, during the adjustment process, by controlling the angle between the support column 15 and the square tube 3, the height of the signal analyzer body 1 can be controlled, thereby improving the convenience of using the signal analyzer.

[0071] When it is necessary to make the display screen and one end of the button of the signal analyzer body 1 tilt upward for the convenience of the operator, the operator can press the slider 13, and the slider 13 drives the cover block 10 to move toward the baffle 24, so that the first air hole 8 is opened, and the operator controls the slide column 4 to be recovered into the square tube 3, so that the gas inside the square tube 3 enters the protection box 5 through the gas channel 19 and the first air hole 8, and enters the airbag ring 6 through the second air hole 25, so that the airbag ring 6 expands and becomes larger. After the adjustment is completed, the slider 13 is released. Under the action of the reset elastic force of the second spring 11, the slider 13 is quickly reset, and the cover block 10 closes the first air hole 8. The elastic supporting force of the second spring 11 is greater than the elastic supporting force of the first spring 9, so that the slide column 4 will not rebound, thereby making the display screen and one end of the button of the signal analyzer body 1 tilt upward.

[0072] After use, fold and recycle Figure 1 Status shown.

[0073] When used outdoors, if direct sunlight affects the operator's viewing of the display screen, the protective box 5 and other structures can be moved upward to adjust to Figure 8 The state shown is then, with the cooperation of the connecting components, the baffle 24 is flipped so that the baffle 24 covers the position above the display screen, thereby achieving a shading effect and improving the practicability of the signal analyzer.
