Description

Technical Field

[0001] The present application relates to the field of signal testing, and in particular to a signal testing box. Background Art

[0002] The signal test box is a tool used to generate, analyze and adjust signals. It can help test and measure the signal performance of electronic equipment, and perform fault diagnosis and troubleshooting. The signal test box mainly includes a box body, a fixture for clamping user equipment (UE), and a control device for controlling the fixture to rotate, move, and other movements.

[0003] The fixture includes two clamping plates arranged at intervals and a driving cylinder for controlling the clamping plates to move in directions of approaching or moving away from each other. When the UE is placed on the fixture, the two clamping plates clamp the UE to support and fix the UE.

[0004] Different test requirements have different requirements for the clamping angle of the UE. Some UEs cannot be fixed in the box by clamping due to structural limitations. However, the length and width of the clamp are fixed, which limits the scope of application of the clamp. When the clamp cannot meet the use conditions, the UE is usually clamped on the clamp with a rubber band, but this will take a lot of time to fix the UE and prolong the fixation time of the UE. Utility Model Content

[0005] In order to improve the structural flexibility of the clamping plate to adapt to different models of UE and different clamping angles and improve the clamping efficiency of the UE, the present application provides a signal test box.

[0006] The signal test box provided in this application adopts the following technical solution:

[0007] A signal test box, comprising a box body, a clamping seat, a clamping rod, a driving device, an adjusting clamping rod and a reset member;

[0008] The clamping seat is installed in the box body, and two clamping rods are provided and the two clamping rods are arranged relatively spaced along the length direction of the clamping seat. The clamping rod is slidably connected to the clamping seat, and the driving device is connected to the clamping rod and is used to control the two clamping rods to slide in the direction of approaching or moving away from each other. The adjusting clamping rod is slidably connected to the end of the clamping rod away from the clamping seat along a sliding direction perpendicular to the clamping rod. The adjusting clamping rod is L-shaped and includes a first rod section parallel to the clamping rod and a second rod section arranged along the sliding direction of the clamping rod, and the second rod section is located on the side of the clamping rod away from the clamping seat. The reset member connects the clamping rod and the adjusting clamping rod, and the reset member is used to drive the adjusting clamping rod to move in a direction close to the clamping rod.

[0009] By adopting the above technical solution, when the UE is clamped between the two clamping rods, the width of the UR is arranged along the length of the clamping rods. When the clamping angle of the UE is changed, the adjusting clamping rod is pulled in a direction away from the clamping rod so that a gap equivalent to the thickness of the UE is generated between the second rod segment and the clamping rod, and the UE is rotated 90 degrees and inserted into the gap to facilitate the placement of UEs at different angles. When the width of the UE is greater than the length of the clamping rod, the adjusting clamping rod is pulled in a direction away from the clamping rod so that the gap from the second rod segment to the clamping seat is the width of the UE, thereby clamping different types of UEs. Thereby, the structural flexibility of the splint is improved as a whole, so as to adapt to different models of UEs and different clamping angles, and improve the clamping efficiency of the UE.

[0010] Optionally, the reset member includes a reset slider and a reset spring, and a reset groove is provided on the side of the two clamping rods facing away from each other for the reset slider to slide along the length direction of the clamping rod. The reset slider is fixedly connected to the first rod section, and the reset spring is arranged along the length direction of the clamping rod, and the two ends of the reset spring are respectively connected to the clamping rod and the reset slider.

[0011] By adopting the above technical solution, when the return spring is extended, the second rod segment abuts against the clamping rod. When the second rod segment moves in a direction away from the clamping rod, the return spring contracts to push the second rod segment to clamp the UE.

[0012] Optionally, the second rod section includes a second main rod and a second branch rod, the second main rod is fixed to the first rod section, a locking groove slidably connected to the second branch rod is opened on the second main rod along the sliding direction of the clamping rod, and a first locking member for locking the position of the second branch rod is arranged between the second main rod and the second branch rod.

[0013] By adopting the above technical solution, when the length of the side wall where the UE abuts against the clamping rod is greater than the clamping rod itself, the second sub-rod is pulled out of the second main rod so that the second sub-rod is located between the two clamping rods, and then the clamping rod is adjusted by pulling in a direction away from the clamping rod until the length between the second sub-rod and the clamp is sufficient to accommodate the UE, thereby improving the structural flexibility and applicability of the entire clamp.

[0014] Optionally, the first locking member includes a locking spring, a locking rotating rod and an arc-shaped locking strip;

[0015] The locking spring is arranged along the sliding direction of the second sub-rod, and the two ends of the locking spring are respectively connected to the second sub-rod and the second main rod. One end of the locking rotating rod is hinged to the second sub-rod along the length direction of the clamping rod. The arc-shaped locking strip is installed on the second main rod. A locking groove for inserting the locking rotating rod is provided on the side of the arc-shaped locking strip facing away from the second main rod.

[0016] By adopting the above technical solution, when the second sub-rod is completely locked in the sliding groove, the locking spring contracts and presses against the second sub-rod, and the locking rotating rod is inserted into the corresponding locking groove. When the second sub-rod slides out of the locking sliding groove, the locking rotating rod moves away from the locking groove, and the locking spring stretches to push the second sub-rod to slide out of the first sub-rod.

[0017] Optionally, the side walls opposite to the second rod section and the clamping rod are both connected with clamping sheets made of silicone material.

[0018] By adopting the above technical solution, when the second rod segment and the clamping rod clamp the UE together, the screen of the UE will face the second rod segment or the clamping rod, and the UE can be protected by the clamping sheet made of silicone material.

[0019] Optionally, the first rod segment is connected to an elastic ring, and a accommodating cavity for accommodating the elastic ring is opened on the side of the first rod segment facing away from the clamping seat, one end of the elastic ring is located outside the accommodating cavity and is connected to an extraction block whose size is larger than the accommodating cavity, and the other end of the elastic ring is connected to a sorting rod, which slides in the accommodating cavity, and a second locking piece for locking the position of the sorting rod is connected between the sorting rod and the first rod segment.

[0020] By adopting the above technical solution, the elastic ring is completely located in the accommodating cavity under normal circumstances. When the UE cannot be fixed by clamping, it is necessary to extract a part of the elastic ring through the extraction block, and determine the length of the elastic ring to be extracted according to the size of the UE. Then, the position of the sorting rod is locked by the second locking member, thereby locking the length of the elastic ring to be extracted, and the UE is clamped on the first rod segment by the elastic ring, thereby achieving fixed support for the UE.

[0021] Optionally, the second locking member includes a first plug ring, a second plug ring and a locking plug rod, the first plug ring is located outside the first rod section and is connected to the organizing rod by a connecting rod, the first rod section is provided with a connecting groove for the connecting rod to slide along the length direction of the clamping rod, the second plug ring is installed on the second rod section and multiple plug rings are arranged at intervals along the length direction of the clamping rod, and the locking plug rod is slidably inserted into the first plug ring and the second plug ring.

[0022] By adopting the above technical solution, when the elastic ring is pulled out, the locking rod is separated from the first and second inserting rings, and the arranging rod slides in the accommodating cavity. When the elastic ring is pulled out to a required length, the locking slide rod is inserted into the corresponding first and second inserting rings to lock the pulled out length of the elastic ring.

[0023] Optionally, the radial cross-section of the elastic ring is L-shaped, and the elastic ring includes a first band segment and a second band segment, the first band segment is located on a side of the second band segment facing the clamping rod, and the second band segment is connected to the inner side of the first band segment.

[0024] By adopting the above technical solution, when the elastic ring clamps the UE, the first band segment of the elastic ring is pressed against the end surface of the UE, and the second band segment supports the top or bottom end of the UE, thereby protecting the UE and preventing the UE from falling.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the clamping angle of the UE is changed, pull the adjusting clamp rod in the direction away from the clamp rod so that a gap equivalent to the thickness of the UE is generated between the second rod segment and the clamp rod, and rotate the UE 90 degrees to insert it into the gap. When the width of the UE is greater than the length of the clamp rod, pull the adjusting clamp rod in the direction away from the clamp rod so that the gap between the second rod segment and the clamp seat is the width of the UE. This improves the overall structural flexibility of the clamp plate to accommodate different types of UE and different clamping angles, thereby improving the clamping efficiency of the UE.

[0027] 2. When the return spring is extended, the second rod segment abuts against the clamping rod. When the second rod segment moves away from the clamping rod, the return spring contracts so that the second rod segment clamps the UE;

[0028] 3. When the length of the side wall where the UE abuts against the clamping rod is greater than the clamping rod itself, pull the second sub-rod out of the second main rod, and then drag the adjustment clamping rod in the direction away from the clamping rod until the length between the second sub-rod and the clamp is sufficient to accommodate the UE, thereby improving the structural flexibility and applicability of the entire clamp.

[0037] The following is combined with Figure 1-6 This application is described in further detail.

[0038] It should be noted that, in the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0039] An embodiment of the present application discloses a signal test box.

[0040] Reference Figure 1 and Figure 2 The signal test box includes a box body 1, a clamping seat 2, a clamping rod 3, a driving device 4 and an adjusting clamping rod 5.

[0041] Among them, the clamping seat 2 is installed in the box body 1, two clamping rods 3 are provided and the two clamping rods 3 are arranged relatively spaced along the length direction of the clamping seat 2, the clamping rod 3 is slidably connected to the clamping seat 2, and the driving device 4 is connected to the clamping rod 3 and is used to control the two clamping rods 3 to slide in the direction of approaching or moving away from each other.

[0042] In addition, the adjusting clamping rod 5 is slidably connected to the end of the clamping rod 3 away from the clamping seat 2 along a sliding direction perpendicular to the clamping rod 3. The adjusting clamping rod 5 is L-shaped and includes a first rod segment 51 parallel to the clamping rod 3 and a second rod segment 52 arranged along the sliding direction of the clamping rod 3. The second rod segment 52 is located on the side of the clamping rod 3 away from the clamping seat 2. Figure 3 As shown, a reset member 6 is connected between the clamping rod 3 and the adjusting clamping rod 5 , and the reset member 6 is used to drive the adjusting clamping rod 5 to move in a direction close to the clamping rod 3 .

[0043] Normally, when the UE is clamped between two clamping rods 3 , the width of the UR is arranged along the length of the clamping rods 3 .

[0044] When the UE is rotated 90 degrees for clamping, the adjusting clamping rod 5 is pulled in a direction away from the clamping rod 3, so that a gap equivalent to the thickness of the UE is generated between the second rod segment 52 and the clamping rod 3, and the UE is inserted into the gap to facilitate the placement of UEs at different angles.

[0045] When the width of the UE is greater than the length of the clamping rod 3 , the clamping rod 5 is pulled away from the clamping rod 3 to adjust the gap between the second rod section 52 and the clamping seat 2 to the width of the UE, thereby clamping different types of UE.

[0046] In addition, when the UE cannot be fixed by clamping, such as Figure 3 and Figure 4 As shown, the first rod segment 51 is connected to an elastic ring 54. A receiving cavity 511 for receiving the elastic ring 54 is provided on one side of the first rod segment 51 away from the clamping seat 2. One end of the elastic ring 54 is located outside the receiving cavity 511 and is connected to an extraction block 55 having a size larger than the receiving cavity 511. The other end of the elastic ring 54 is connected to a tidying rod 56. The tidying rod 56 slides in the receiving cavity 511. A second locking member 57 for locking the position of the tidying rod 56 is connected between the tidying rod 56 and the first rod segment 51.

[0047] The length of the elastic ring 54 to be drawn out needs to be determined according to the size of the UE, and then the position of the arrangement rod 56 is locked by the second locking member 57, thereby locking the length of the elastic ring 54 to be drawn out, and the UE is clamped on the first rod segment 51 by the elastic ring 54, and the UE is pressed against the first rod segment 51 and the second rod segment 52. Thus, the structural flexibility of the clamping plate is improved as a whole, so as to be applicable to different models of UE and different clamping angles, and the clamping efficiency of the UE is improved.

[0048] Reference Figure 3 The reset member 6 includes a reset slider 61 and a reset spring 62. A reset slot 31 is provided on the side of the two clamping rods 3 that are away from each other, and the reset slider 61 is provided to slide along the length direction of the clamping rod 3. The reset slider 61 is fixedly connected to the first rod section 51, and the reset spring 62 is arranged along the length direction of the clamping rod 3. The two ends of the reset spring 62 are respectively connected to the clamping rod 3 and the reset slider 61. When the reset spring 62 is extended, the second rod section 52 abuts against the clamping rod 3. When the second rod section 52 moves in a direction away from the clamping rod 3, the reset spring 62 contracts to facilitate pushing the second rod section 52 to clamp the UE.

[0049] Reference Figure 3 and Figure 4The second rod section 52 and the side wall opposite to the clamping rod 3 are both connected with a clamping sheet 7 made of silicone material, and the clamping sheet 7 made of silicone material can protect the UE when clamping the UE.

[0050] Reference Figure 3 and Figure 4 The second rod section 52 includes a second main rod 521 and a second sub-rod 522. The second main rod 521 is fixed to the first rod section 51, and a locking groove 523 slidably connected to the second sub-rod 522 is provided on the second main rod 521 along the sliding direction of the clamping rod 3, and a first locking member 53 for locking the position of the second sub-rod 522 is provided between the second main rod 521 and the second sub-rod 522.

[0051] The first locking member 53 includes a locking spring 531, a locking rod 532 and an arc-shaped locking strip 533. The locking spring 531 is arranged along the sliding direction of the second sub-rod 522, and the two ends of the locking spring 531 are respectively connected to the second sub-rod 522 and the second main rod 521, one end of the locking rod 532 is hinged to the second sub-rod 522 along the length direction of the clamping rod 3, and the arc-shaped locking strip 533 is installed on the second main rod 521. A locking groove 534 for inserting the locking rod 532 is provided on the side of the arc-shaped locking strip 533 away from the second main rod 521.

[0052] When the second sub-rod 522 is completely locked in the slide groove 523, the locking spring 531 contracts and presses against the second sub-rod 522, and the locking rotating rod 532 is inserted into the corresponding locking groove 534. When the length of the side wall where the UE abuts against the clamping rod 3 is greater than the clamping rod 3 itself, the locking rotating rod 532 moves away from the locking groove 534, and the locking spring 531 stretches to push the second sub-rod 522 to slide out of the second main rod 521. Then, the clamping rod 5 is pulled away from the clamping rod 3 until the length between the second sub-rod 522 and the clamping rod is sufficient to accommodate the UE, thereby improving the structural flexibility and applicability of the entire clamp.

[0053] Reference Figure 4 and Figure 5 The second locking member 57 includes a first plug ring 571, a second plug ring 572 and a locking plug rod 573. The first plug ring 571 is located outside the first rod section 51 and is connected to the arranging rod 56 by a connecting rod. The first rod section 51 is provided with a connecting groove 574 for the connecting rod to slide along the length direction of the clamping rod 3. The second plug ring 572 is installed on the second rod section 52 and is spaced apart along the length direction of the clamping rod 3. The locking plug rod 573 is slidably inserted into the first plug ring 571 and the second plug ring 572.

[0054] When the elastic ring 54 is pulled out, the locking rod 573 is separated from the first and second inserting rings 571 and 572, and the arranging rod 56 slides in the accommodating cavity 511. When the elastic ring 54 is pulled out to a required length, the locking slide bar is inserted into the corresponding first and second inserting rings 571 and 572 to lock the pulled out length of the elastic ring 54.

[0055] To prevent UE from falling when clamping UE, refer to Figure 5 and Figure 6 The radial cross section of the elastic ring 54 is L-shaped. The elastic ring 54 includes a first band segment 541 and a second band segment 542. The first band segment 541 is located on the side of the second band segment 542 facing the clamping rod 3, and the second band segment 542 is connected to the inner side of the first band segment 541. When the elastic ring 54 clamps the UE, the first band segment 541 of the elastic ring 54 is pressed against the end surface of the UE, and the second band segment 542 supports the top or bottom end of the UE to protect the UE.

[0056] The implementation principle of a signal test box in an embodiment of the present application is as follows: under normal circumstances, when two clamping rods 3 clamp the UE, the width of the UR is arranged along the length of the clamping rods 3 .

[0057] When the UE needs to be rotated 90 degrees for clamping, that is, to clamp the screen and back of the UE, the adjustment clamping rod 5 needs to be pulled in a direction away from the clamping rod 3 so that a gap equivalent to the thickness of the UE is generated between the second rod segment 52 and the clamping rod 3, and the UE is inserted into the gap.

[0058] When the width of the UE is greater than the length of the clamping rod 3 , the clamping rod 5 is pulled away from the clamping rod 3 to adjust the gap between the second rod section 52 and the clamping seat 2 to the width of the UE, so that the UE is pressed against the second segment rod 522 and the clamping seat 2 .

[0059] When the UE cannot be fixed by clamping, the UE is clamped on the first rod segment 51 by the elastic ring 54, thereby improving the structural flexibility of the clamping plate as a whole, so as to be suitable for different types of UE and different clamping angles, and improving the clamping efficiency of the UE.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
