Description

Technical Field

[0001] This application belongs to the field of testing devices, specifically relating to a testing fixture. Background Technology

[0002] Typically, atomizing devices require environmental testing. Specifically, when the atomizing device is encased in a bag, during high-temperature testing, the air or gas inside the bag expands upon heating, increasing the internal pressure and causing the bag to swell. Similarly, during negative-pressure testing, the external pressure of the bag is lower than the internal pressure, also causing the bag to swell. When conducting batch testing of atomizing devices with encased bags, they are usually bundled and secured close together before testing. However, this method can cause the bags to expand during testing, potentially leading to compression between adjacent bags and affecting test results. Utility Model Content

Furthermore, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0025] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0026] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] like Figures 1 to 5As shown, the test fixture includes: a support frame assembly 10, which includes a connecting rod 11; multiple clamping assemblies 20, all of which are connected to the connecting rod 11 and are spaced apart along the extension direction of the connecting rod 11. Each clamping assembly 20 is slidably connected to the connecting rod 11 and is configured to clamp the packaging bag of the item to be tested. The distance between two adjacent clamping assemblies 20 is adjustable so that the packaging bags of adjacent items to be tested are spaced apart.

[0028] In this embodiment, since multiple clamping components 20 are all connected to the connecting rod 11, and each clamping component 20 is slidably connected to the connecting rod 11, the distance between adjacent clamping components 20 can be adjusted by the distance between adjacent clamping components 20, so that the distance between adjacent clamping components is appropriate, and each clamping component 20 can clamp the packaging bag of the item to be tested, realizing batch testing of the atomizing device. Moreover, the multiple clamping components 20 are distributed at intervals along the extension direction of the connecting rod 11, which can ensure that there is a gap between the packaging bags of adjacent items to be tested, thereby avoiding mutual squeezing of the packaging bags of adjacent items to be tested when testing the items to be tested.

[0029] That is, in this embodiment, by setting multiple sets of clamping components 20 distributed at intervals along the extension direction of the connecting rod 11, and each set of clamping components 20 being slidably connected to the connecting rod 11, the positions of two adjacent sets of clamping components 20 relative to the connecting rod 11 can be adjusted so that each set of clamping components 20 clamps the packaging bag of the item to be tested, thereby enabling the testing of a batch of items to be tested. Furthermore, the spacing between two adjacent sets of clamping components 20 can be adjusted to ensure that there is a gap between the packaging bags of adjacent items to be tested, avoiding the problem of adjacent packaging bags of items to be tested squeezing each other and affecting the test results during the test. In other words, in this embodiment, the test results of the items to be tested can be improved.

[0030] It should be noted that, in this embodiment, the packaging bag of the item to be tested can be the packaging bag of the atomizing device. In this case, when multiple sets of clamping components 20 are spaced apart along the extension direction of the connecting rod 11, each set of clamping components 20 can clamp the packaging bag of the atomizing device, realizing batch testing of the atomizing device. Furthermore, the spaced distribution of multiple sets of clamping components 20 along the extension direction of the connecting rod 11 ensures that there is a gap between adjacent packaging bags. Even if the packaging bag expands, there is a gap between adjacent packaging bags, preventing adjacent packaging bags from squeezing each other when expanding, effectively reducing the risk of packaging bag bursting. Of course, the packaging bag of the item to be tested can also be the packaging bag of products in other fields.

[0031] Additionally, in some embodiments, each clamping assembly 20 includes at least two clamping members spaced apart along the extension direction of the connecting rod, and at least one of the clamping members is slidably connected to the connecting rod so that the distance between the at least two clamping members is adjustable; wherein, the at least two clamping members are configured to clamp the packaging bag of the item to be tested.

[0032] Specifically, each clamping assembly 20 includes a first clamping member 21 and a second clamping member 22. The first clamping member 21 and the second clamping member 22 are spaced apart along the extension direction of the connecting rod 11. At least one of the first clamping member 21 and the second clamping member 22 is slidably connected to the connecting rod 11 so that the distance between the first clamping member 21 and the second clamping member 22 is adjustable. The first clamping member 21 and the second clamping member 22 are configured to clamp the object to be tested.

[0033] Since the first clamping member 21 and the second clamping member 22 are spaced apart along the extension direction of the connecting rod 11, and at least one of the first clamping member 21 and the second clamping member 22 is slidably connected to the connecting rod 11, the distance between the first clamping member 21 and the second clamping member 22 can be adjusted by adjusting the clamping components 20 that are slidably connected to the connecting rod 11. This ensures that the distance between the first clamping member 21 and the second clamping member 22 is appropriate, and that the first clamping member 21 and the second clamping member 22 clamp the item to be tested. Furthermore, the multiple sets of clamping components 20 are spaced apart along the extension direction of the connecting rod 11, allowing each set of clamping components 20 to clamp the item to be tested, thus enabling batch testing of the atomizing device. The spaced distribution of multiple sets of clamping components 20 along the extension direction of the connecting rod 11 also ensures that there is a gap between adjacent items to be tested, thereby preventing adjacent items from squeezing each other when testing products in the atomizing device field.

[0034] It should be noted that, in this embodiment of the application, both the first clamping member 21 and the second clamping member 22 can be slidably connected to the connecting rod 11, so that when clamping the item to be tested, the position of the first clamping member 21 relative to the connecting rod 11 can be adjusted, and the position of the second clamping member 22 relative to the connecting rod 11 can also be adjusted, so that the first clamping member 21 and the second clamping member 22 clamp the item to be tested.

[0035] Of course, the first clamping member 21 can also be slidably connected to the connecting rod 11, and the second clamping member 22 can be fixed relative to the connecting rod 11. Thus, when clamping the object to be tested, the position of the first clamping member 21 relative to the connecting rod 11 can be adjusted so that the first clamping member 21 and the second clamping member 22 clamp the object to be tested.

[0036] The second clamping member 22 can also be slidably connected to the connecting rod 11, and the first clamping member 21 can be fixed relative to the connecting rod 11. Thus, when clamping the object to be tested, the position of the second clamping member 22 relative to the connecting rod 11 can be adjusted so that the first clamping member 21 and the second clamping member 22 clamp the object to be tested.

[0037] Of course, in this embodiment, each clamping assembly 20 may also include other numbers of clamping members. For example, each clamping assembly 20 may include three clamping members, at least one of which is slidably connected to the connecting rod 11; or, for another example, each clamping assembly 20 may include four clamping members, at least one of which is slidably connected to the connecting rod 11. The specific number of clamping members included in each clamping assembly 20 is not limited in this embodiment.

[0038] In addition, in some embodiments, a groove 111 is provided on the connecting rod 11 along its extending direction, and a clamping member slidably connected to the connecting rod 11 is connected to a sliding rod, which is slidably connected to the groove 111. Specifically, as shown... Figure 2 As shown, when the clamping assembly 20 includes a first clamping member 21 and a second clamping member 22, the first clamping member 21 is connected to a first sliding rod 211, which is slidably connected to the slide groove 111; and / or, the second clamping member 22 is connected to a second sliding rod 221, which is slidably connected to the slide groove 111.

[0039] Because the connecting rod 11 has a groove 111, when the first clamping member 21 is connected to the first sliding rod 211, the first sliding rod 211 can be slidably connected to the groove 111, thereby achieving a slidable connection between the first clamping member 21 and the connecting rod 11; when the second clamping member 22 is connected to the second sliding rod 221, the second sliding rod 221 can be slidably connected to the groove 111, thereby achieving a slidable connection between the second clamping member 22 and the connecting rod 11. In other words, by providing the groove 111 on the connecting rod 11, it is convenient for the first clamping member 21 to slide with the connecting rod 11, and it is also convenient for the second clamping member 22 to slide with the connecting rod 11.

[0040] It should be noted that, in some cases, only the first clamping member 21 can be connected to the first sliding rod 211, in which case the first clamping member 21 is slidably connected to the connecting rod 11, and the second clamping member 22 is fixed relative to the connecting rod 11; in other cases, the second clamping member 22 can be connected to the second sliding rod 221, in which case the second clamping member 22 is slidably connected to the connecting rod 11, and the first clamping member 21 is fixed relative to the connecting rod 11; in still other cases, the first clamping member 21 can be connected to the first sliding rod 211, and the second clamping member 22 can be connected to the second sliding rod 221, in which case both the first clamping member 21 and the second clamping member 22 are slidably connected to the connecting rod 11.

[0041] In some embodiments, the slide groove 111 passes through the connecting rod 11, the sliding rod passes through the slide groove 111, and a fastener is connected to the sliding rod. The fastener and the clamping member are located on opposite sides of the connecting rod, respectively.

[0042] Specifically, when the clamping assembly 20 includes a first clamping member 21 and a second clamping member 22, a first sliding rod 211 passes through the slide groove 111, and a first fastener 212 is connected to the first sliding rod 211. The first fastener 212 and the first clamping member 21 are located on opposite sides of the connecting rod 11, respectively; and / or, a second sliding rod 221 passes through the slide groove 111, and a second fastener 222 is connected to the second sliding rod 221. The second fastener 222 and the second clamping member 22 are located on opposite sides of the connecting rod 11, respectively.

[0043] Since the groove 111 passes through the connecting rod 11, the first sliding rod 211 can pass through the groove 111, and the first fastener 212 is connected to the first sliding rod 211. This is equivalent to the first clamping member 21 being slidably connected to the connecting rod 11. Thus, when it is necessary to clamp the packaging bag of the item to be tested, the position of the first clamping member 21 relative to the connecting rod 11 can be adjusted, that is, the first sliding rod 211 slides in the groove 111. Once the first sliding rod 211 slides to the appropriate position, it can be fixed by the first fastener 212, avoiding the problem that the first clamping member 21 may shake when clamping the packaging bag of the item to be tested with the second clamping member 22, which is not conducive to the clamping of the packaging bag of the item to be tested.

[0044] In addition, when the slide groove 111 passes through the connecting rod 11, the second sliding rod 221 can pass through the slide groove 111, and the second fastener 222 is connected to the second sliding rod 221. This is equivalent to the second clamping member 22 being slidably connected to the connecting rod 11. Thus, when it is necessary to clamp the item to be tested, the position of the second clamping member 22 relative to the connecting rod 11 can be adjusted, that is, the second sliding rod 221 slides in the slide groove 111. Once the second sliding rod 221 slides to the appropriate position, it can be fixed by the second fastener 222. This avoids the problem that the second clamping member 22 may shake when the first clamping member 21 and the second clamping member 22 clamp the packaging bag of the item to be tested, which is not conducive to the clamping of the packaging bag of the item to be tested.

[0045] In addition, when the slide groove 111 passes through the connecting rod 11, the first sliding rod 211 can also pass through the slide groove 111, and the second sliding rod 221 can also pass through the slide groove 111. Thus, the first clamping member 21 is slidably connected to the connecting rod 11, and the second clamping member 22 is slidably connected to the connecting rod 11. The position of the first clamping member 21 relative to the connecting rod 11 and the position of the second clamping member 22 relative to the connecting rod 11 can be adjusted, so that the first clamping member 21 and the second clamping member 22 clamp the packaging bag of the item to be tested. The first sliding rod 211 is fixed by the first fastener 212, and the second sliding rod 221 is fixed by the second fastener 222. This avoids the problem that the first clamping member 21 and the second clamping member 22 may shake when clamping the packaging bag of the item to be tested, which would be detrimental to the clamping of the packaging bag of the item to be tested.

[0046] It should be noted that the first sliding rod 211 can be a threaded rod, the second sliding rod 221 can also be a threaded rod, the first fastener 212 can be a nut, and the second fastener 222 can also be a nut.

[0047] Additionally, in some embodiments, such as Figure 1 or Figure 4 As shown, the test fixture also includes a base 30 and multiple support frame assemblies 10. Each support frame assembly 10 is connected to multiple clamping assemblies 20. The multiple support frame assemblies 10 are slidably connected to the base 30, and the multiple support frame assemblies 10 are distributed at intervals along the first direction X, which intersects with the extension direction of the connecting rod 11.

[0048] Since multiple support frame assemblies 10 are slidably connected to the base 30 and are spaced apart along the first direction X, when testing batches of items to be tested, the packaging bags of the items to be tested can be clamped by multiple sets of clamping components 20 on each support frame assembly 10. The position of the first clamping member 21 and / or the second clamping member 22 in each set of clamping components 20 relative to the connecting rod 11 ensures that each set of clamping components 20 can clamp the packaging bags of the items to be tested. Furthermore, the gap between adjacent sets of clamping components 20 on each support frame assembly 10 prevents the packaging bags of the items to be tested from squeezing each other. Additionally, by adjusting the position of two adjacent support frame assemblies 10 relative to the base 30, the distance between two adjacent support frame assemblies 10 can be avoided from being too close, thus preventing the packaging bags of the items to be tested clamped by the clamping components 20 on adjacent support frame assemblies 10 from squeezing each other, improving the testing effect, and effectively reducing the risk of packaging bags bursting.

[0049] By setting multiple support frame components 10 that are slidably connected to the base 30, the position of each support frame component 10 relative to the base 30 can be adjusted. In addition, the position of each support frame component 10 relative to the base 30 can be adjusted according to the size of the packaging bag of the item to be tested, so that items of different sizes can be clamped and tested.

[0050] Additionally, in some embodiments, such as Figure 1 As shown, the support frame assembly 10 also includes a first support rod 12 and a second support rod 13; the first end of the first support rod 12 is connected to the first end of the connecting rod 11, the first end of the second support rod 13 is connected to the second end of the connecting rod 11, the first support rod 12 and the connecting rod 11 have a first included angle, and the second support rod 13 and the connecting rod 11 have a second included angle; the second ends of the first support rod 12 and the second ends of the second support rod 13 are both slidably connected to the base 30.

[0051] Since the first support rod 12 and the connecting rod 11 have a first included angle, and the second support rod 13 and the connecting rod 11 have a second included angle, the first support rod 12, the connecting rod 11, and the second connecting rod 11 essentially form a frame structure. Furthermore, the first support rod 12 and the second support rod 13 have minimal impact on the multiple clamping components 20 on the connecting rod 11, ensuring that the multiple clamping components 20 on the connecting rod 11 can effectively clamp the object to be tested. In addition, the second ends of both the first support rod 12 and the second support rod 13 are slidably connected to the base 30, allowing both ends of the connecting rod 11 to slide relative to the base 30. Therefore, when it is necessary to adjust the position of the connecting rod 11 relative to the base 30, the first support rod 12 and the second support rod 13 can slide relative to the base 30, thus adjusting the position of the connecting rod 11 relative to the base 30.

[0052] By setting the first support rod 12 and the second support rod 13, it is possible not only to ensure that the first support rod 12 and the second support rod 13 support the connecting rod 11, but also to facilitate the sliding connection between the connecting rod 11 and the base 30. This allows multiple sets of clamping components 20 on the multiple connecting rods 11 to clamp the packaging bag of the item to be tested, thereby realizing batch testing of the item to be tested.

[0053] It should be noted that the first included angle can be 90°, but it can also be other values, such as 89° or 91°. It is sufficient to ensure that the first support rod 12 is perpendicular or nearly perpendicular to the connecting rod 11. The specific angle of the first included angle is not limited in this embodiment. Similarly, the second included angle can be 90°, but it can also be other values, such as 89° or 91°. It is sufficient to ensure that the second support rod 13 is perpendicular or nearly perpendicular to the connecting rod 11. The specific angle of the second included angle is not limited in this embodiment.

[0054] Additionally, in some embodiments, such as Figure 1 and Figure 4 As shown, the base 30 is provided with a first sliding groove 31 and a second sliding groove 32; the first sliding groove 31 and the second sliding groove 32 are distributed at intervals along the extension direction of the connecting rod 11, the first sliding groove 31 extends along the first direction X, and the second sliding groove 32 extends along the first direction X; the second end of the first support rod 12 is slidably connected to the first sliding groove 31, and the second end of the second support rod 13 is slidably connected to the second sliding groove 32.

[0055] Because the base 30 is provided with a first sliding groove 31 and a second sliding groove 32, the second end of the first support rod 12 can be slidably connected to the first sliding groove 31, and the second end of the second support rod 13 can be slidably connected to the second sliding groove 32. This allows the first end of the connecting rod 11 to slide relative to the base 30, and also allows the second end of the connecting rod 11 to slide relative to the base 30, thus changing the position of the connecting rod 11 relative to the base 30. In other words, by providing the first sliding groove 31 and the second sliding groove 32, the connecting rod 11 can be easily slidably connected to the base 30.

[0056] Additionally, in some embodiments, such as Figure 4 As shown, both the first sliding groove 31 and the second sliding groove 32 penetrate the base 30; the second end of the first support rod 12 is connected to the first slide rod 121, and the second end of the second support rod 13 is connected to the second slide rod 131. The first slide rod 121 passes through the first sliding groove 31, and the second slide rod 131 passes through the second sliding groove 32; the first slide rod 121 is connected to the first fixing member 122, and the second slide rod 131 is connected to the second fixing member 132. The first fixing member 122 and the clamping assembly 20 are located on opposite sides of the base 30, and the second fixing member 132 and the clamping assembly 20 are located on opposite sides of the base 30, respectively.

[0057] Since both the first sliding groove 31 and the second sliding groove 32 penetrate the base 30, the first sliding rod 121 passes through the first sliding groove 31, and the second sliding rod 131 passes through the second sliding groove 32. When the sliding groove 111 penetrates the connecting rod 11, the first sliding rod 121 is connected to the first fixing member 122, and the second sliding rod 131 is connected to the second fixing member 132. Therefore, when it is necessary to adjust the position of the support plate relative to the base 30, the first sliding rod 121 can slide in the first sliding groove 31. Once the first sliding rod 121 slides to the appropriate position, it can be fixed by the first fixing member 122. Similarly, the second sliding rod 131 can slide in the second sliding groove 32. Once the second sliding rod 131 slides to the appropriate position, it can be fixed by the second fixing member 132. This ensures that when the connecting rod 11 moves to the appropriate position, the position of the connecting rod 11 relative to the base 30 is fixed.

[0058] By setting the first slide bar 121, the second slide bar 131, the first fixing member 122 and the second fixing member 132, it is possible to ensure that the position of the connecting rod 11 can be adjusted relative to the base 30. Once the position of the connecting rod 11 is adjusted to a suitable position, the position of the connecting rod 11 is fixed, thereby avoiding the problem that the connecting rod 11 may shake, which is not conducive to testing the atomizing device.

[0059] It should be noted that the first slide rod 121 can be a threaded rod, and the second slide rod 131 can also be a threaded rod. The first fixing part 122 can be a nut, and the second fixing part 132 can also be a nut.

[0060] Additionally, in some embodiments, such as Figure 4 As shown, at least one support platform 301 is provided on the surface of the base 30 opposite to the clamping assembly 20; the at least one support platform 301 is distributed at intervals on the surface of the base 30 opposite to the clamping assembly 20. With this arrangement, the base 30 can be supported by the support platform 301 to ensure that the base 30 can be stable.

[0061] It should be noted that the number of support platforms 301 can be set according to actual needs. For example, if there are 4 support platforms 301, they will be distributed at intervals; or if there are 8 support platforms 301, they will be distributed at intervals. The specific number of support platforms 301 is not limited in this embodiment.

[0062] Additionally, in some embodiments, such as Figure 5As shown, the clamping component includes: a clamping body 23, a first clamping rod 24, and a second clamping rod 25; the clamping body 23 of the clamping component is slidably connected to the connecting rod 11, the first end of the first clamping rod 24 and the first end of the second clamping rod 25 are both connected to the clamping body 23, the second end of the first clamping rod 24 is connected to the second end of the second clamping rod 25, and the extension direction of the first clamping rod 24 intersects the extension direction of the second clamping rod 25; wherein, the second end of the first clamping rod 24 and the second end of the second clamping rod 25 are configured to clamp the packaging bag of the item to be tested.

[0063] Since the clamping body 23 of the clamping member is slidably connected to the connecting rod 11, when it is necessary to make at least two clamping members slide relative to the connecting rod 11, the clamping body 23 of each clamping member can slide relative to the connecting rod 11, thereby adjusting the position of at least two clamping members relative to the connecting rod 11.

[0064] In addition, the first end of the first clamping rod 24 and the first end of the second clamping rod 25 are both connected to the clamping body 23, and the second end of the first clamping rod 24 is connected to the second end of the second clamping rod 25. Therefore, when the first clamping member 21 and the second clamping member 22 need to clamp the packaging bag of the item to be tested, the second end of the first clamping rod 24 and the second end of the second clamping rod 25 can clamp the packaging bag of the item to be tested. That is, the packaging bag of the item to be tested is clamped at the intersection of the first clamping rod 24 and the second clamping rod 25, ensuring that the contact area of ​​the item to be tested is small. When the item to be tested is a packaging bag, the risk of the packaging bag bursting when it is collided can be reduced.

[0065] It should be noted that when the first clamping member 21 is connected to the first sliding rod 211, the clamping body 23 of the first clamping member 21 is connected to the first sliding rod 211; when the second clamping member 22 is connected to the second sliding rod 221, the clamping body 23 of the second clamping member 22 is connected to the second sliding rod 221.

[0066] Additionally, in some embodiments, such as Figure 5As shown, the clamping body 23 includes a first plate 231, a second plate 232, a third plate 233, a fourth plate 234, a fifth plate 235, and a fixing rod 236. The second plate 232 and the third plate 233 are both connected to the first plate 231, and the second plate 232 and the third plate 233 are spaced apart along the extension direction of the connecting rod 11. The fourth plate 234 and the fifth plate 235 are spaced apart along the first direction X. A first connecting plate 237 is connected to the surface of the fourth plate 234 facing the fifth plate 235, and a second connecting plate 238 is connected to the surface of the fifth plate 235 facing the fourth plate 234. The fixing rod 236 connects the second plate 232, the first connecting plate 237, the second connecting plate 238, and the third plate 233. The first end of the first clamping rod 24 is connected to the end of the fourth plate 234 away from the connecting rod 11, and the first end of the second clamping rod 25 is connected to the end of the fifth plate 235 away from the connecting rod 11. With this configuration, the first clamping rod 24 and the second clamping rod 25 protrude significantly from the clamping body 23, which in turn facilitates the clamping of the object to be tested by the second ends of the first clamping rod 24 and the second clamping rod 25.

[0067] It should be noted that the number of first connecting plates 237 connected to the surface of the fourth plate 234 facing the fifth plate 235 can be set according to actual needs. For example, the number of first connecting plates 237 is two, and the two first connecting plates 237 are distributed at intervals along the extension direction of the connecting rod 11; or, for another example, the number of first connecting plates 237 is one. In this respect, the embodiments of this application are not limited.

[0068] Furthermore, the number of second connecting plates 238 connected to the surface of the fifth plate 235 facing the fourth plate 234 can be set according to actual needs. For example, the number of second connecting plates 238 can be two, and the two second connecting plates 238 can be distributed at intervals along the extension direction of the connecting rod 11; or, for another example, the number of second connecting plates 238 can be one. In this respect, the embodiments of this application are not limited.

[0069] Additionally, in some embodiments, such as Figure 5 As shown, the clamping components also include: an elastic element 239; one end of the elastic element 239 is connected to the surface of the fourth plate 234 facing the fifth plate 235, and the other end of the elastic element 239 is connected to the surface of the fifth plate 235 facing the fourth plate 234. This arrangement avoids a rigid connection between the fourth plate 234 and the fifth plate 235, facilitating the clamping of the packaging bag of the item to be tested by at least two clamping components.
