Description

Technical Field

[0001] This utility model relates to the field of positioning fixture technology, specifically to a positioning fixture component for coupling testing. Background Technology

[0002] During POS machine coupling testing, a positioning fixture is required to correctly position the POS machine and the transmitter board. Existing positioning fixtures, such as... Figure 11 As shown, a test launcher is installed on the positioning base plate 1, and internal thread support columns are set at the four corners of the positioning base plate 1. The positioning panel 2 is installed on the top of the four internal thread support columns. At the same time, the positioning panel 2 has corresponding limiting holes. Screws are passed through the limiting holes and threadedly connected to the internal thread support columns to fix the positioning base plate 1 and the positioning panel 2 relative to each other. Limiting components for positioning the POS machine are installed on the positioning panel 2 for coupling testing.

[0003] In the existing positioning fixtures described above, the positioning base plate 1 is a universal component with a fixed position for the transmitter plate; however, the positioning panel 2 is a specific component because the limiting components differ for different POS machine models. When using the positioning fixture, if the positioning base plate 1 and positioning panel 2 are used together after installation, it occupies storage space and wastes resources; if they are used separately, although the number of positioning base plates 1 can be reduced, repeated disassembly and assembly result in significant screw wear, easy stripping of threads, and inconvenience in screw removal and assembly. To solve the above problems, this utility model provides a positioning fixture assembly for coupling testing. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a positioning fixture assembly for coupling testing, in which the upper narrow column of the stepped column is installed in the positioning hole, and a limiting mechanism is installed between the upper narrow column and the positioning hole; this facilitates disassembly, reduces resource waste of the positioning base plate, reduces storage space, and solves the technical problems mentioned in the background art.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a positioning fixture assembly for coupling testing, comprising: a positioning panel detachably installed on a positioning base plate, stepped columns installed at the four corners of the upper surface of the positioning base plate, positioning holes corresponding to the positions of the stepped columns being opened at the four corners of the positioning panel, the upper narrow column of the stepped column being installed in the positioning hole, and a limiting mechanism being installed between the upper narrow column and the positioning hole.

[0006] Preferably, the limiting mechanism includes an elastic rubber sleeve, which is fitted into the positioning hole. A limiting rubber ring is integrally formed on the inner side of the elastic rubber sleeve, and a limiting ring groove A is integrally formed on the outer periphery of the middle part of the upper narrow column. The limiting rubber ring is fitted into the limiting ring groove A.

[0007] Preferably, a limiting protrusion is integrally provided coaxially on the inner circumference of the positioning hole, and a limiting ring groove B corresponding to the position of the limiting rubber ring is provided coaxially on the outer circumference of the elastic rubber sleeve. The limiting protrusion is installed in the limiting ring groove B, and the limiting ring groove B and the limiting protrusion have a horizontal expansion space. By providing the limiting ring groove B on the outside of the elastic rubber sleeve for installing the limiting protrusion, the elastic rubber sleeve can be stably installed, while facilitating the disassembly and replacement of the elastic rubber sleeve. In addition, the horizontal expansion space between the limiting ring groove B and the limiting protrusion allows the limiting rubber ring to have expansion space when compressed, making it convenient and practical.

[0008] Preferably, the top of the upper narrow column is an integrally connected frustum head; the frustum head design of the upper narrow column makes it easy for the upper narrow column to pass through the limiting rubber ring, which is convenient and practical.

[0009] Preferably, a launcher plate is mounted on the upper surface of the positioning base plate; the stepped columns provide space for mounting the launcher plate, which is used for coupling testing.

[0010] Preferably, a U-shaped limiting strip for positioning the test piece is installed on the upper surface of the positioning panel; the test piece is a POS machine, and the position and shape of the U-shaped limiting strip vary depending on the model and size of the POS machine.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. During installation, after the upper narrow column is aligned with the lower part of the elastic rubber sleeve, press the positioning panel firmly. The top of the upper narrow column will then pass through the limiting rubber ring, allowing the limiting rubber ring to be fitted into the limiting ring groove A. At this point, the limiting rubber ring is unlikely to slip out of the limiting ring groove A, ensuring that the positioning panel is stably mounted on the positioning base plate, meeting the coupling test requirements. During disassembly, fix the positioning panel and pull it upwards forcefully. The limiting rubber ring will deform under pressure, smoothly separating the upper narrow column and the positioning panel. This design facilitates disassembly, reduces resource waste of the positioning base plate, saves storage space, and is convenient and practical.

[0013] 2. This utility model provides a limiting ring groove B on the outside of the elastic rubber sleeve for installing the limiting protrusion ring, which satisfies the need for stable installation of the elastic rubber sleeve and facilitates the disassembly and replacement of the elastic rubber sleeve. In addition, the limiting ring groove B and the limiting protrusion ring have a horizontal expansion space, which allows the limiting rubber ring to have expansion space when it is squeezed, making it convenient and practical.

[0014] 3. This utility model features a rounded top of the narrow upper column, which facilitates the insertion of the limiting rubber ring through the narrow upper column, making it convenient and practical. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] like Figures 1 to 11 As shown, this embodiment provides a positioning fixture assembly for coupling testing, including: a positioning panel 2 detachably mounted on a positioning base plate 1; stepped columns 3 installed at the four corners of the upper surface of the positioning base plate 1; positioning holes 4 corresponding to the positions of the stepped columns 3 opened at the four corners of the positioning panel 2; upper narrow columns 31 of the stepped columns 3 installed in the positioning holes 4; and a limiting mechanism installed between the upper narrow columns 31 and the positioning holes 4. By installing the upper narrow columns 31 in the positioning holes 4, the lower wide columns of the stepped columns 3 can support the positioning panel 2, while the limiting mechanism securely limits the positioning panel 2 to the four upper narrow columns 31, ensuring convenient and stable installation of the positioning panel 2. Specifically, a launch plate 11 is installed on the upper surface of the positioning base plate 1, and the stepped columns 3 provide space for the launch plate 11, which is used for coupling testing. More specifically, a U-shaped limiting strip 21 for positioning the test piece is installed on the upper surface of the positioning panel 2; the test piece is a POS machine, and the position and shape of the U-shaped limiting strip 21 vary depending on the model and size of the POS machine.

[0031] Please see Figures 3 to 10 As shown, the limiting mechanism includes an elastic rubber sleeve 5, which is fitted into the positioning hole 4. A limiting ring 51 is integrally formed on the inner side of the elastic rubber sleeve 5, with a semi-circular cross-section to allow the upper narrow post 31 to pass through the inner side of the limiting ring 51. A limiting ring groove A311 is integrally formed on the outer periphery of the middle part of the upper narrow post 31, and the limiting ring 51 is fitted into the limiting ring groove A311. In actual use, although the inner diameter of the limiting ring 51 is larger than that of the upper narrow post 31, the limiting ring 51 is made of elastic rubber and will deform under pressure. When the upper narrow post 31 is fitted into the lower part of the elastic rubber sleeve 5, the top of the upper narrow post 31 can pass through the limiting ring 51 by pressing the positioning panel 2, and then the limiting ring 51 is fitted into the limiting ring groove A311. At this point, the limiting rubber ring 51 is not easily slipped out of the limiting ring groove A311, ensuring that the positioning panel 2 is stably installed on the positioning base plate 1, meeting the coupling test requirements. During disassembly, the positioning panel 2 is fixed, and the positioning panel 2 is pulled upwards with force. The limiting rubber ring 51 is deformed after being squeezed, successfully separating the upper narrow column 31 and the positioning panel 2. This facilitates disassembly, reduces resource waste of the positioning base plate 1, reduces storage space, and is convenient and practical.

[0032] Example 2:

[0033] Please see Figure 4 and Figures 8 to 10 As shown, a limiting protrusion 41 is integrally and coaxially provided on the inner circumference of the positioning hole 4, and a limiting ring groove B52 corresponding to the position of the limiting ring 51 is provided on the outer circumference of the elastic rubber sleeve 5. The limiting protrusion 41 is installed in the limiting ring groove B52. A telescopic space 512 is left between the limiting ring groove B52 and the limiting protrusion 41 in the horizontal direction. The inner diameter of the limiting protrusion 41 here is larger than the outer diameter of the upper narrow column 31 to ensure that the upper narrow column 31 passes through the elastic rubber sleeve 5. The limiting ring groove B52 provided on the outside of the elastic rubber sleeve 5 for installing the limiting protrusion 41 ensures stable installation of the elastic rubber sleeve 5 and facilitates the disassembly and replacement of the elastic rubber sleeve 5. In addition, the telescopic space 512 left between the limiting ring groove B52 and the limiting protrusion 41 in the horizontal direction allows for telescopic space when the limiting ring 51 is compressed, which is convenient and practical.

[0034] Example 3:

[0035] Please see Figure 4 and Figure 6 As shown, the top of the upper narrow column 31 is an integrally connected frustum head 312. The design of the frustum head 312 at the top of the upper narrow column 31 makes it easy for the upper narrow column 31 to pass through the limiting rubber ring 51, which is convenient and practical.

[0036] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
