[0031] Currently, the floating plate inside the test chamber is typically limited by multiple screws, and springs inside the chamber support the floating plate. When testing is required, the floating plate is pressed down, exposing the probe inside the chamber for product testing. When repairing or replacing the probes, the limiting screws need to be disassembled or installed individually. However, due to the small size of the floating plate, disassembling and reassembling multiple screws simultaneously is cumbersome, reducing the efficiency of the floating plate's assembly and disassembly.

[0032] Figure 1 A schematic diagram of the limiting structure according to an embodiment of the present invention is shown. Figure 1 As shown, this utility model proposes a limiting structure and a testing device. The limiting structure of this utility model includes a base 10, a floating plate 20, and a limiting member 30. The top of the base 10 is provided with a receiving groove, and the outer side of the base 10 is provided with a through hole, which connects the inside of the receiving groove and the outside of the base 10. The axial direction of the through hole intersects with the moving direction of the receiving groove. The floating plate 20 is disposed in the receiving groove and can move along the moving direction of the receiving groove. The limiting member 30 is disposed in the through hole and can move along the axial direction of the through hole. The limiting member 30 can move into the receiving groove and abut against the floating plate 20 to restrict the floating plate 20 from moving out of the receiving groove.

[0033] By using the limiting structure in this technical solution, the limiting member 30 can move to the receiving groove and abut against the floating plate 20, thereby limiting the floating plate 20 and preventing it from moving out of the receiving groove. At the same time, the limiting member 30 can move along the through hole axially and retract into the through hole, canceling the abutment against the floating plate 20, thus facilitating the removal of the floating plate 20 from the receiving groove. The limiting structure of this utility model achieves the limiting and removal of the floating plate 20 by moving the limiting member 30, simplifying the disassembly and installation of the floating plate 20 and improving the disassembly and installation efficiency.

[0034] In some embodiments of this utility model, a positioning groove 22 is provided on the side of the floating plate 20 facing the through hole. The limiting member 30 can move into the positioning groove 22 and abut against the side of the positioning groove 22 facing the bottom surface of the receiving groove. In this embodiment, after the limiting member 30 moves into the positioning groove 22, it can limit the circumferential movement of the floating plate 20, thereby ensuring that the floating plate 20 can only move along the moving direction of the receiving groove during operation, and will not rotate along the axial direction of the floating plate 20, thus improving the reliability of the floating plate 20 during operation.

[0035] Specifically, in this embodiment, the positioning groove 22 has a first opening on the side facing the through hole. The first opening facilitates the insertion of the limiting member 30 into the positioning groove 22, thereby enabling the limiting member 30 to abut against the side of the positioning groove 22 facing the bottom surface of the receiving groove, thus limiting and fixing the floating plate 20. Additionally, the positioning groove 22 has a second opening on the side facing away from the bottom surface of the receiving groove. The second opening allows operators to observe whether the limiting member 30 has inserted into the positioning groove 22, thereby determining whether the limiting of the floating plate 20 has been achieved, improving reliability.

[0036] Specifically, in other embodiments of this utility model, the positioning groove 22 may also have a third opening only on the side facing the through hole, so that the limiting member 30 is inserted into the positioning groove 22 through the third opening, thereby realizing the fixing and limiting of the floating plate 20 by the limiting member 30.

[0037] In some embodiments of this utility model, multiple positioning grooves 22 are provided, spaced apart circumferentially along the floating plate 20. Multiple through holes are also provided, spaced apart circumferentially along the base 10. Multiple limiting members 30 are provided, each correspondingly positioned within one of the through holes and capable of moving into one of the positioning grooves 22. In this embodiment, the multiple positioning grooves 22 and the multiple through holes are equally spaced, ensuring that the multiple positioning grooves 22 circumferentially along the floating plate 20 are evenly connected by the multiple limiting members 30, further guaranteeing the circumferential positioning of the floating plate 20 and improving reliability.

[0038] In some embodiments of this utility model, the limiting member 30 includes an insertion part 31 and a locking part 32 connected at an angle greater than 0 degrees and less than 180 degrees. The insertion part 31 is disposed in the through hole, and the locking part 32 is located outside the through hole and can abut against the outer peripheral side of the base 10. In this embodiment, both the insertion part 31 and the locking part 32 are plate structures. The insertion part 31 can be inserted into the through hole and can move along the axial direction of the through hole. When the end of the insertion part 31 away from the locking part 32 moves into the positioning groove 22, the locking part 32 abuts against the outer peripheral surface of the base 10, which can ensure the degree of fit between the insertion part 31 and the positioning groove 22, and further ensure the precise fit between the limiting member 30 and the floating plate 20.

[0039] Specifically, in this embodiment, the locking part 32 and the insertion part 31 are arranged vertically, which makes it convenient for the operator to push and pull the limiting member 30 as a whole through the locking part 32, thereby improving the convenience of the operator to move the limiting member 30.

[0040] In some embodiments of this utility model, the axial dimension of the insertion part 31 along the through hole is larger than the axial dimension of the through hole. In this embodiment, the above-mentioned arrangement can ensure that the end of the insertion part 31 facing away from the locking part 32 can be stably and accurately inserted into the positioning groove 22, thereby realizing the limiting member 30's limiting abutment against the floating plate 20.

[0041] In some embodiments of this utility model, the limiting structure further includes a guide member, which is disposed within the through hole and sleeved outside the limiting member 30, with the limiting member 30 and the guide member slidably connected. In this embodiment, the guide member can guide the internal limiting member 30 to move accurately toward the positioning groove 22, thereby ensuring a tight fit between the limiting member 30 and the positioning groove 22.

[0042] Specifically, in this embodiment, the guide member and the limiting member 30 are in a sliding fit. The sliding fit between the guide member and the limiting member 30 has a vibration reduction and buffering effect, which can effectively reduce vibration and noise. In addition, the sliding fit between the guide member and the limiting member 30 can also reduce the friction force during the movement of the limiting member 30, further facilitating the operator's movement operation.

[0043] In some embodiments of this utility model, the guide member includes a first guide portion, a second guide portion, and a third guide portion. The first guide portion and the second guide portion are spaced apart and connected to the same side of the third guide portion. The first guide portion, the second guide portion, and the third guide portion enclose a guide cavity. The limiting member 30 is disposed in the guide cavity and is slidably connected to the first guide portion and the second guide portion, respectively. In this embodiment, the guide member has a U-shaped structure that covers the limiting member 30. In this embodiment, the side of the first guide portion facing the second guide portion and the side of the second guide portion facing the first guide portion are respectively provided with a first slide rail and a second slide rail. The first slide rail and the second slide rail are slidably connected to the opposite sides of the insertion portion 31 of the limiting member 30, which facilitates the movement of the limiting member 30 and improves the axial movement accuracy of the limiting member 30 along the through hole.

[0044] Specifically, in this embodiment, the connection between the guide and the through hole can be an interference fit to ensure the stability of the fixation between the through hole and the guide.

[0045] In some embodiments of this invention, the floating plate 20 has an opening 21, the axis of which is parallel to the moving direction of the receiving groove. The opening 21 is used for probe extension. In this embodiment, the opening 21 facilitates the extension of the probe of the testing device, thereby enabling the testing of the test piece on the floating plate 20.

[0046] In some embodiments of this utility model, the limiting structure further includes an elastic element, which is connected to the bottom surface of the receiving groove and the floating plate 20 respectively. In this embodiment, the elastic element can exert an elastic force on the floating plate 20, so that the floating plate 20 always maintains an elastic force facing away from the bottom surface of the receiving groove. The limiting element 30 is inserted into the through hole and moves to the positioning groove 22, which can ensure that the floating plate 20 is always located in the receiving groove.

[0047] Furthermore, the limiting structure of this utility model changes the fixing method of the floating plate 20 from screw fixing to a quick-release method in which the limiting member 30 cooperates with the positioning groove 22, so that the limiting member 30 can be pulled open or pushed in directly when the floating plate 20 is disassembled and assembled, and the floating plate 20 can be quickly picked up and put in, saving time and improving disassembly and assembly efficiency.

[0048] This utility model also proposes a testing device, comprising:

[0049] The limiting structure is the limiting structure described above;

[0050] The probe is connected to the bottom surface of the receiving groove and passes through the floating plate 20. The floating plate 20 can move relative to the probe along the moving direction of the receiving groove. The probe is used to test the test piece on the floating plate 20.

[0051] By using the testing device in this technical solution, which employs a combination of a limiting structure and a probe, when the test piece is placed on the floating plate 20 and pressed towards the bottom surface of the receiving groove, the probe inserted inside the floating plate 20 can be exposed, thus facilitating the probe's testing of the test piece. The limiting member 30 can move into the receiving groove and abut against the floating plate 20, thereby limiting the floating plate 20 and preventing it from moving out of the receiving groove. Simultaneously, the limiting member 30 can move axially along the through hole and retract into the through hole, releasing its abutment against the floating plate 20, thus facilitating the removal of the floating plate 20 from the receiving groove. The limiting structure of this invention, through the movement of the limiting member 30, achieves the limiting and removal of the floating plate 20, simplifying the disassembly and installation of the floating plate 20 and improving disassembly and installation efficiency.

[0052] Specifically, in this embodiment, the probe is located inside the opening 21. When the limiting member 30 moves into the positioning groove 22 to limit the floating plate 20, the top of the probe is lower than the opening of the side of the opening 21 that is away from the bottom surface of the receiving groove. When the floating plate 20 moves toward the bottom surface of the receiving groove, the probe will slowly be exposed through the opening 21.

[0053] Furthermore, the operating procedure of the testing device of this utility model is as follows: When the floating plate 20 needs to be installed in the receiving groove, the floating plate 20 is first pressed into the receiving groove, and then multiple limiting members 30 are pushed into the positioning groove 22 of the floating plate 20 in sequence, thereby realizing the limiting and fixing of the floating plate 20 by the limiting members 30. When testing is required, the test piece is first placed on the floating plate 20, and then the floating plate 20 is pressed towards the bottom surface of the receiving groove, which can expose the probe through the opening 21 of the floating plate 20, thereby realizing the contact between the probe and the test piece, and completing the test of the test piece by the probe.

[0054] When it is necessary to disassemble the floating plate 20, first press the floating plate 20 towards the bottom of the receiving groove to prevent the floating plate 20 from popping out of the receiving groove after the limiting member 30 is released. Then pull the multiple limiting members 30 out of the positioning groove 22 of the floating plate 20, and finally remove the floating plate 20 along the moving direction of the receiving groove.

[0055] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
