[0038] The on-off valve line a and the test pin 2200 can be connected by welding, and the welding process is simple and stable.

[0039] In addition, the mounting block 1000 can be made of insulating material to prevent leakage.

[0040] In this embodiment, during assembly, the mounting block 1000 is engaged with at least a portion of the side 1012 of the boss 101 via the limiting device 1300, and the mounting block 1000 is connected to the test gauge 10 via the fixing device 1200, so that the test probe 2200 is connected to the male connector of the test gauge 10. The switch valve line a is led out from the sealing test equipment and connected to the test probe 2200 of the female connector 2000, thus completing the assembly. Then, the subsequent switch valve test can be performed.

[0041] The following section uses the ultrasonic gas meter under test (Table 10) as an example to illustrate the assembly process of the sealing test switch valve tooling 100 in more detail:

[0042] The casing of the ultrasonic gas meter has a boss 101 for supporting the male connector, such as... Figure 4 As shown, the male connector of the air-mounted plug protrudes from the upper surface 1011 of the boss 101. In order to further improve the assembly efficiency of the sealing test switch valve tooling 100 and make it easier to align the test needle 2200 with the male connector of the air-mounted plug of the test gauge 10, a limiting device 1300 is provided in this embodiment.

[0043] According to an optional embodiment of the present invention, the limiting device 1300 includes a first limiting part 1310 and a second limiting part 1320 connected to the first limiting part 1310. The first limiting part 1310 is used to abut against a portion of the side surface 1012 of the boss 101, and the second limiting part 1320 is used to abut against another portion of the side surface 1012 of the boss. The first limiting part 1310 and the second limiting part 1320 cooperate to achieve engagement with the boss 101.

[0044] Specifically, refer to Figure 3 and Figure 4 Taking boss 101 as a rectangular platform as an example, in Figure 4 From a certain perspective, the rectangular platform includes four sides 1012: top, bottom, left, and right. The limiting device 1300 can then be configured as an L-shaped protrusion, with the first limiting part 1310 and the second limiting part 1320 each being one side of the L-shaped protrusion. The limiting device 1300 can be located at one corner of the mounting block 1000. During assembly, the limiting device 1300 is aligned with one corner of the rectangular platform, for example... Figure 4The lower right corner of the rectangular table is aligned with the lower right corner of the perspective lower limit device 1300, so that the inner wall of the first limiting part 1310 abuts against the side surface 1012 on the right side of the rectangular table, and the inner wall of the second limiting part 1320 abuts against the side surface 1012 on the lower side of the rectangular table, that is, the limiting device 1300 is clamped and matched with the boss 101, and then the upper surface 1011 of the rectangular table is attached to the second surface 1002 of the mounting block 1000, so that the preliminary positioning of the relative position between the mounting block 1000 and the detected table 10 is completed, that is, the preliminary alignment of the test needle 2200 and the aviation plug male head is achieved, and then the connection relationship between the test needle 2200 and the aviation plug male head is locked under the action of the positioning device.

[0045] Therefore, the setting of the limiting device 1300 can more conveniently achieve the accurate alignment between the test needle 2200 and the aviation plug male head, and can play a limiting role to prevent the position deviation between the test needle 2200 and the aviation plug male head in the subsequent working process, thereby more effectively improving the efficiency of the switch valve test of the detected table 10.

[0046] It is easy to understand that the above embodiment is only described by taking the boss 101 as a rectangular table as an example, and the shape of the limiting device 1300 is not specifically limited in actual working conditions; for example, if the boss 101 on the shell of the detected table 10 is a circular table, the limiting device 1300 can be set as an arc-shaped protrusion, the curvature of the inner wall of the arc-shaped protrusion can be matched with the curvature of the side surface 1012 of the circular table, and in general, the inner wall of the limiting device 1300 can be clamped and limited with the boss 101.

[0047] Therefore, the sealing detection switch valve tool 100 can facilitate the positioning of the aviation plug female head 2000 by setting the fixing device 1200 and the limiting device 1300 on the mounting block 1000, thereby improving the efficiency of the switch valve test of the detected table 10.

[0048] It should be noted that in the present embodiment, the limiting device 1300 is set to be capable of clamping at least part of the side surface 1012 of the boss 101 (that is, the limiting device 1300 is not a closed annular structure), which is only for the convenience of assembling the sealing detection switch valve tool 100. Figure 3 and Figure 4 As shown, when the boss 101 is a rectangular table and the limiting device 1300 is an L-shaped protrusion, the limiting device 1300 only clamps the two side surfaces 1012 of the rectangular table (that is, Figure 4 the two side surfaces 1012 on the lower side and the right side of the boss 101), which is more convenient in assembly and can be applied to rectangular tables of different sizes.

[0049] However, in actual working conditions, the limiting device 1300 can also be a closed ring structure; specifically, still taking the rectangular platform 101 as an example, the limiting device can also be a closed rectangular frame, and when assembling, the limiting device 1300 is clamped with all the four side surfaces 1012 of the rectangular platform.

[0050] Therefore, whether the limiting device 1300 is a closed ring structure, that is, whether the limiting device can be clamped with all the side surfaces 1012 of the convex platform 101 as a whole, is not limited, and can be determined according to actual working conditions.

[0051] Specifically, as shown in Figures 1 to 6 According to an optional embodiment of the utility model, the mounting hole 1100 penetrates the mounting block 1000, the test needle 2200 penetrates the female head body 2100 along the extension direction of the mounting hole 1100, the part of the test needle 2200 in the mounting hole 1100 is used for connecting with the jack male head of the detected table 10, and the part of the test needle 2200 outside the mounting hole 1100 is used for connecting with the switch valve line a.

[0052] In the embodiment, it is easy to understand that the mounting hole 1100 is arranged to penetrate the mounting block 1000, and the test needle 2200 penetrates the female head body 2100 along the extension direction of the mounting hole 1100, which can more conveniently assemble the jack female head 2000 in the mounting hole 1100.

[0053] Continuing to refer to Figures 1 to 6 According to an optional embodiment of the utility model, along the extension direction of the mounting hole 1100, the mounting block 1000 comprises the first surface 1001 and the second surface 1002 arranged correspondingly, and the fixing device 1200 is configured to connect the second surface 1002 with the shell of the detected table 10. Specifically, the fixing device 1200 is a magnet 1210, the magnet 1210 is arranged on the second surface 1002, and the magnet 1210 is used for adsorbing the second surface 1002 to the shell of the detected table 10.

[0054] Among them, two clamping grooves can be arranged on the second surface 1002, and two magnets 1210 are distributed and clamped into the two clamping grooves, so as to realize the assembly of the magnet 1210;

[0055] It is easy to understand that the number of the magnet 1210 and the connection mode thereof with the second surface 1002 in the embodiment are only for specific description, and can be determined according to actual working conditions, without specific limitation.

[0056] In this embodiment, when assembling the sealing detection switch valve tool 100, only the second surface 1002 of the mounting block 1000 is adsorbed to the shell of the detected meter 10 by the magnet 1210, and the relative fixation between the mounting block 1000 and the detected meter 10 can be achieved. The method of adsorbing the shell of the detected meter 10 by the magnet 1210 is simple and convenient, and the test pin 2200 can be aligned with the male plug of the detected meter 10.

[0057] Therefore, in this way, the efficiency of the switch valve test of the detected meter 10 can be further improved.

[0058] According to an optional embodiment of the utility model, the inner wall of the mounting hole 1100 is used for clamping with the outer wall of the male plug.

[0059] In this embodiment, it is easy to understand that the clamping of the mounting hole 1100 with the outer wall of the male plug can further improve the accuracy of the alignment between the test pin 2200 and the male plug.

[0060] It should be noted that the shape of the mounting block 1000 and the mounting hole 1100 is not limited, and can be determined according to the shape of the male plug under actual working conditions.

[0061] For example, the mounting block 1000 in Figures 1 to 4 is a complete rectangular block; and Figure 5 and Figure 6 The mounting block 1000 in Figure 5 can be regarded as a rectangular block with an opening at one corner. It is easy to understand that as long as the shape and size of the mounting block 1000 match the male plug of the detected meter 10, Figure 6 The mounting block 1000 in will not affect the assembly of the final sealing detection switch valve tool 100.

[0062] Figure 1 As shown in , specifically, according to an optional embodiment of the utility model, the inner wall of the mounting hole 1100 is provided with a plurality of ball springs 1110, and the plurality of ball springs 1110 are arranged at intervals around the circumference of the mounting hole 1100.

[0063] In this embodiment, in order to further improve the connection stability between the mounting block 1000 and the detected meter 10, and improve the convenience of the alignment between the test pin 2200 and the male plug, a plurality of ball springs 1110 are arranged at intervals on the inner wall of the mounting hole 1100. Under the action of the ball springs 1110, the clamping between the mounting hole 1100 and the outer wall of the male plug can be more stable, and when disassembling is needed, the mounting block 1000 can also be more conveniently pulled out of the male plug.

[0064] It is easy to understand that the plurality of ball springs 1110 can be uniformly spaced around the circumference of the mounting hole 1100, so that the force of the male connector and the mounting block 1000 is more uniform, thereby further ensuring the stability of the connection between the two.

[0065] In addition, if the shell of the test meter 10 is made of a material that is not easily attracted by the magnet 1210, the ball spring 1110 can also function as a fixing device 1200, thereby improving the use scenario of the sealing detection on-off valve tool 100.

[0066] In addition, if the shell of the test meter 10 is made of a material that is not easily attracted by the magnet 1210, the ball spring 1110 can also function as a fixing device 1200, thereby improving the use scenario of the sealing detection on-off valve tool 100. Figure 1 Figure 5 For example, it should be noted that Figure 1 Figure 5 Only one of the magnet 1210 and the ball spring 1110 is retained in each figure for ease of labeling, but in actual working conditions, the sealing detection on-off valve tool 100 can include both the magnet 1210 and the ball spring 1110.

[0067] Continuing to refer to Figures 1 to 6 According to an optional embodiment of the present application, the sealing detection on-off valve tool 100 further includes a protective block 3000, the protective block 3000 is fixedly connected with the mounting block 1000, and the protective block 3000 has a protective cavity for accommodating the portion of the test needle 2200 located outside the mounting hole 1100.

[0068] In this embodiment, the protective block 3000 is provided to prevent the connection between the on-off valve line a and the test needle 2200 from loosening due to pulling or the like.

[0069] Since the portion of the test needle 2200 located outside the mounting hole 1100 is located in the protective cavity, that is, the connection position of the on-off valve line a and the test needle 2200 is also protected by the protective block 3000, therefore, the provision of the protective block 3000 can effectively prevent the connection between the on-off valve line a and the test needle 2200 from loosening, thereby further ensuring the efficiency of the on-off valve test of the test meter 10.

[0070] It is easy to understand that the protective block 3000 can be provided with a through hole, and the on-off valve line a can pass through the through hole to enter the protective cavity to be connected with the on-off valve line a.

[0071] In addition, the wiring of the on-off valve line a can be bound together in the protective cavity by a strap or the like, to further ensure the stability of the on-off valve line a, thereby protecting the on-off valve line a.

[0072] For example, it should be noted that Figures 1 to 6 ​​As shown, according to an optional embodiment of the utility model, the sealing detection switch valve tool 100 further comprises a connecting block 4000, the connecting block 4000 is fixedly connected with the first surface 1001, and the aviation plug female head 2000 is fixedly connected with the connecting block 4000.

[0073] In the embodiment, the aviation plug female head 2000 needs to be fixed in the mounting hole 1100, and the connecting block 4000 is arranged for facilitating assembly, and the aviation plug female head 2000 is fixedly connected with the connecting block 4000; during assembly, the aviation plug female head 2000 is first inserted into the mounting hole 1100, and then the connecting block 4000 is fixedly connected with the first surface 1001 of the mounting block 1000, so that the aviation plug female head 2000 can be finally fixed in the mounting hole 1100.

[0074] It is easy to understand that when the sealing detection switch valve tool 100 further comprises the protective block 3000, the protective block 3000 can be fixedly connected with the mounting block 1000 through the connecting block 4000.

[0075] According to an optional embodiment of the utility model, the mounting block 1000 is an ebonite block.

[0076] In the embodiment, the ebonite block has good insulation, heat resistance, corrosion resistance and high mechanical strength, and is suitable for electrical materials.

[0077] Similarly, when the sealing detection switch valve tool 100 further comprises the protective block 3000 and the connecting block 4000, the protective block 3000 and the connecting block 4000 can also be ebonite blocks, and the specific reasons are the same as above and will not be repeated.

[0078] The utility model embodiment further provides a kind of sealing detection assembly, and sealing detection assembly includes sealing detection equipment and the sealing detection switch valve tool 100 of any one described above, and sealing detection equipment is connected with the test needle 2200 of sealing detection switch valve tool 100 by switch valve line a.

[0079] In the embodiment, the sealing detection equipment has the same beneficial effects as any one of the sealing detection switch valve tools 100 described above, which can improve the efficiency of switch valve testing of the detected meter 10, and the specific analysis can refer to the analysis of any one of the sealing detection switch valve tools 100 described above, which will not be repeated here.

[0080] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can easily think of changes or replacements within the technical range disclosed by the utility model, which should be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
