[0003] The boiling test is a commonly used method for testing plastic parts. The product is immersed in hot water at a preset temperature in a boiling box. After keeping it for a preset period of time, the product is taken out and various properties (such as strength, pressure resistance, etc.) of the boiled product are evaluated.

[0004] However, in the prior art, when performing a water boiling test, the test pieces are usually placed horizontally on the storage surface of the shelf and immersed in the hot water in the water boiling tank. In this way, each test piece will be heated unevenly due to the large contact area with the shelf; secondly, the storage surface space is limited, which will cause the intervals between the test pieces to be too small, and even cause accumulation, which will adversely affect the test accuracy. In addition, the laying arrangement method can only test a small number of test pieces at a time, resulting in low test efficiency. In addition, multiple test pieces are scattered on the shelf in a disordered manner, which is not conducive to conveniently removing these test pieces from the water boiling tank.

[0005] Therefore, it is necessary to provide a boiling water test system that can test a large number of test pieces at one time while ensuring the test accuracy. Utility Model Content

In the present utility model, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or number limitation. The term "multiple" refers to two or more, unless otherwise clearly defined.

[0029] The following will refer to Figures 1 to 4 Various embodiments of the water boiling test system according to the utility model are described in detail.

[0030] Figure 1 FIG. 2 shows a three-dimensional schematic diagram of an embodiment of a water boiling test system according to the present utility model. Figure 1 As shown, the water boiling test system 1 of the present invention comprises a water boiling tank 11 and a fixing device 12. The fixing device 12 comprises at least one hanging member 13 and a holding assembly 14, and the fixing device 12 is arranged inside the water boiling tank 11 as a whole. The first end of the hanging member 13 is removably connected to the holding assembly 14, so that the first end can be kept at the upper part of the water boiling tank 11, and the second end of the hanging member 13 is suitable for connecting at least one test piece 2. The hanging member 11 is arranged along the height direction of the water boiling tank 11 as a whole, so that the first end of the hanging member is kept at the upper part of the water boiling tank 11 and exposed to the liquid in the water boiling tank, and the second end of the hanging member can be suspended in the liquid in the water boiling tank. In this way, the at least one test piece 2 connected to the second end of the hanging member 13 can also be suspended inside the water boiling tank 11.

[0031] In the technical field, the water boiling box 11 is usually provided with a heating device (not shown in the figure) inside. When performing a water boiling test, the heating device heats the liquid in the water boiling box 11 to a preset temperature so that the test piece is immersed in the heated liquid for the water boiling test. The water boiling box 11 can have any structure known in the art, and this embodiment is not limited thereto.

[0032] It should be noted that “at least one test piece is suspended inside the water boiling tank 11 ” means that the test piece or the test piece among the multiple test pieces that is last connected to the second end of the hanging member 13 is substantially not in contact with the bottom or side wall of the water boiling tank 11 .

[0033] According to the water boiling system of the utility model, when testing, multiple hanging parts can be hung on the upper part of the water boiling box by means of the holding assembly, and multiple test pieces can be connected to each hanging part. In this way, the internal space of the water boiling box in the height direction is fully utilized, and a large number of test pieces can be arranged inside the water boiling box at one time, thereby improving the test efficiency.

[0034] Furthermore, the test pieces are suspended inside the water boiling box by means of the suspension parts, so that they will not be heated unevenly, and there will be no accumulation between the test pieces, thereby ensuring the accuracy of the test. Specifically, on the one hand, for multiple test pieces, these test pieces are suspended inside the water boiling box by means of the suspension parts. Since their environmental conditions such as temperature in the height direction of the water boiling box are basically the same, the consistency of the state (temperature, etc.) of the multiple test pieces in the water boiling box during the test is ensured, thereby ensuring the accuracy of the test results; on the other hand, for individual test pieces, the suspended test pieces basically do not have a large area of ​​contact with other parts, thereby ensuring that each part of each test piece can be heated evenly during the test, thereby ensuring the accuracy of the test results. More accurate test results help to screen more suitable material types and / or improve materials more reasonably.

[0035] In addition, since the hanging piece is simply hooked on the holding assembly and one end of the hanging piece is located at the upper part of the water boiling tank and exposed outside the liquid, the test piece can be conveniently removed from the inside of the water boiling tank by moving the hanging piece, so as to sample individual test pieces during the test and / or organize the test tools after the test.

[0036] Combine the following Figure 2 and Figure 3 The structure of the hanging member and the retaining assembly of the fixing device and the connection method between the two are described in detail.

[0037] Figure 2 Shows Figure 1 Schematic diagram of an embodiment of a suspension member of a water boiling test system. Figure 2As shown, the suspension member 13 may have a curved section 131 at a first end and a straight section 132 at a second end. The curved section 131 may be held on the upper portion of the water boiling tank 11 by means of the holding assembly 22, so that the straight section 132 can be suspended inside the water boiling tank 11. For example, Figure 3 As shown, the holding assembly 14 may include a hanging member 142, and the hanging member 142 has at least one through hole 143 for the curved section 131 to pass through. The curved section 131 can be retained on the upper part of the water boiling tank 11 by cooperating with the through hole 143. At least one test piece 2 is connected in series to the straight section 132 for hanging, so that the at least one test piece 2 is suspended inside the water boiling tank 11.

[0038] Refer to the following Figure 2 The curved and straight sections of the suspension are described in detail.

[0039] The bent section 131 may be partially arc-shaped so as to smoothly fit into the through hole on the holding assembly 14. Figure 2 , the curved section 131 may include a guide portion 133, a retaining portion 134 and a hanging portion 135. The hanging portion 135 is connected between the guide portion 133 and the retaining portion 134 and is in an arc shape. The end of the guide portion 133 away from the hanging portion 135 is a free end. Here, "free end" refers to an end that is not connected to other components or is not constrained by other components. The end of the retaining portion 134 away from the hanging portion 135 is connected to the straight section 132. In addition, the guide portion 133 and the retaining portion 134 are at least partially arranged opposite to each other. In this way, the guide portion 133, the hanging portion 135 and the retaining portion 134 form a U-shaped opening with a certain depth. Of course, the three can also form other suitable shapes, such as an arch. The recess formed by the arc of the hanging portion 135 is arranged toward the bottom of the water boiling box 11. Figure 2 In the illustrated embodiment, the guide portion 133 and the retaining portion 134 are both substantially straight and substantially parallel to each other, thereby facilitating the positioning and retaining of the curved section.

[0040] When the hanging member 13 is fitted into the through hole on the holding assembly, the guide portion 133 of the curved section 131 first enters and passes through the through hole, thereby playing a guiding and positioning role, and then the arc-shaped hanging portion 135 contacts and cooperates with the hanging member 142, and finally stably hangs on the holding assembly 14 through the guide portion 133 and the holding portion 134. It can be understood that when the hanging member is hung on the through hole on the holding assembly, the guide portion 133 and the holding portion 134 of the curved section 131 are respectively located on both sides of the edge defining the through hole, wherein the guide portion 133 passes through the through hole and is located on the inner side of the through hole; the holding portion 134 is located on the outer side of the through hole; and the hanging portion 135 partially passes through the through hole and partially contacts with the edge defining the through hole, that is, a part of the hanging portion 135 is located on the inner side of the through hole, and the other part is located on the outer side of the through hole.

[0041] The straight section 132 may be substantially straight so that a greater number of test pieces can be connected in series thereon. Figure 2 The straight section 132 may include a transition section 136 and a series connection section 137. The transition section 136 is connected between the series connection section 137 of the straight section 132 and the retaining section 134 of the curved section 131, that is, the transition section 136 is used to connect the straight section 132 and the curved section 131. Figure 2 In the embodiment shown, the serial connection portion 137 is substantially in a straight line shape, based on which a plurality of test pieces can be conveniently serially connected to the serial connection portion 137. Figure 2 The transition portion 136 in the embodiment is also substantially linear. In this case, the two can be formed integrally, thereby simplifying the processing technology. In other embodiments, the transition portion 136 can have other shapes, such as an arc shape with a smaller curvature. Of course, in the case where the transition portion 136 is not linear, the transition portion 136 and the serial connection portion 137 can also be formed integrally. It can be understood that the length of the serial connection portion 137 is related to the number of test pieces and can be specifically set according to actual needs. For example, when the number of test pieces is large, the length of the serial connection portion 137 is designed to be longer.

[0042] Refer to the following Figure 3 The structure of the holding assembly 14 is described in detail. As described above, the holding assembly 14 may include a hanger 142, referring to Figure 3 The holding assembly 14 may further include a side support frame 141, and the hanging member 142 is arranged on the side support frame 141. The side support frame 141 may be arranged at the bottom of the water boiling tank 11, so as to stably support the hanging member 142.

[0043] The hanging member 142 may be an elongated member arranged along the length direction or width direction of the water boiling box 11, that is, the extension direction of the hanging member 142 is parallel to the length direction or width direction of the water boiling box 11. Here, "elongated member" refers to a member whose length is much greater than its width. The hanging member 142 may be provided with at least one through hole 143 at intervals along its length direction, so that a large number of hanging members 13 can be hung on the upper part of the water boiling box 11, which helps to improve the test efficiency.

[0044] like Figure 1 and Figure 3 As shown, the hanger 142 can be configured as a cross bar arranged along the width direction of the water boiling tank 11, that is, the extension direction of the hanger 142 is parallel to the width direction of the water boiling tank 11. The cross section of the hanger 142 can be circular. In other embodiments, the hanger 142 can extend along other directions and can also have other cross sections, such as square. Figure 3 In the illustrated embodiment, only one row of through holes is provided on the hanger 142 , but in other embodiments, the plurality of through holes on the hanger 142 may have different distribution patterns, for example, the plurality of through holes are arranged in two rows parallel to each other along the width direction of the hanger 142 .

[0045] In order to support and fix the hanger 142, refer to Figure 3 , the side support frame 141 may include a support beam 144. The support beam 144 may have a receiving groove 145 to clamp the two ends of the hanging member 142 inside the receiving groove 145. Based on this, the two ends of the hanging member 142 are in contact with the support beam 144 through the receiving groove 145, and the two ends are firmly embedded in the receiving groove 145 due to their own gravity. Figure 3 As shown, the support beam 144 may have a plurality of accommodating grooves 145 along its length. The accommodating grooves 145 may have notches (not shown) for accommodating both ends of the hanger 142. When the hanger 142 is configured as the above-mentioned crossbar, the support beam 144 may be configured as a longitudinal beam accordingly. Figure 1 and Figure 3 The distribution pattern of the hangers 142 on the support beam 144 is only schematically shown, but is not limited thereto.

[0046] By cooperating with the receiving grooves at both ends, the hanging member 142 is removably arranged on the side support frame 141. In this way, when the number of through holes on the hanging member 142 needs to be changed, the hanging member 142 can be conveniently removed from the side support frame 141 to be replaced with other suitable hanging members 142 or the removed hanging member 142 can be modified.

[0047] The hanging member 142 can also be removably arranged on the side support frame 141 in other ways, not limited to the above-mentioned ways. For example, in other embodiments, the hanging member 142 can be fixed to the side support frame by means such as welding, that is, the hanging member 142 and the side support frame are equivalent to an integral part. When in use, they only need to be placed in the water boiling box 11 as a whole without any assembly steps, which is more convenient.

[0048] Refer again Figure 3 The side support frame 141 may further include a reinforcing beam 146 and two groups of columns 147 (only one group of columns arranged on one side of the water boiling box is shown in the figure). The two groups of columns 147 are arranged across the length of the hanging member 142 and supported at the bottom of the water boiling box along the height direction of the water boiling box; and two columns in each group of columns 147 support the support beam 144 at both ends of the support beam 144, respectively, so as to ensure the stability of the entire holding assembly 14 in the longitudinal direction. The reinforcing beam 146 is connected between two oppositely arranged columns in the two groups of columns 147, so as to ensure the stability of the entire holding assembly 14 in the transverse direction. In this way, the side support frame 141 and the reinforcing beam 146 form a frame that is basically in the shape of a rectangular parallelepiped. The reinforcing beam and the columns may be connected by welding or the like.

[0049] In addition to the above-mentioned suspension and retaining components, such as Figure 3 As shown, in order to prevent the hanging member and / or the test piece from falling to the bottom of the water boiling tank, the fixing device 12 may further include a bottom shelf 15. The bottom shelf 15 may be positioned relative to the holding assembly 14 and arranged below the holding assembly 14, and at least a portion of the bottom shelf 15 has a pore 152. With the aid of the pore 152, the water in the water boiling tank 11 can pass through the bottom shelf 15, thereby soaking the test piece 2 suspended above the bottom shelf 15. Since the position of the bottom shelf 15 corresponds to the holding assembly 14, the position of the bottom shelf 15 also corresponds to the hanging member 13 and the test piece 2 suspended on the holding assembly 14. Based on this, when the hanging member 13 and / or the test piece 2 fall due to an accident or the like, the bottom shelf 15 can receive the hanging member 13 and / or the test piece 2, preventing them from falling to the bottom of the water boiling tank 11 and affecting the test accuracy.

[0050] The bottom shelf 15 may have a mesh structure. Figure 3 For example, the bottom shelf 15 may include a plurality of structures 151, which are arranged in a crisscross pattern to form a mesh structure with pores 152. Of course, the bottom shelf 15 may have any suitable structure that can receive the dropped hanging member 13 and / or the sample 2 and allow the water in the water boiling tank 11 to pass therethrough.

[0051] Refer to the following Figure 4 To describe in detail the connection method between the suspension and the specimen.

[0052] Figure 4 The schematic diagram of the water boiling test system according to the present invention is shown in which a suspension member is connected to the fixing device. For the convenience of description, the structure of the suspension member and the holding assembly is simplified in the figure. Figure 4 In this embodiment, the specimen 2 connected in series by the hanger 13 may have a through hole 21. In this way, a plurality of specimens 2 may be connected in series on the hanger 13 in sequence by passing the straight section 132 through the through hole 21. Here, the "through hole" refers to a hole that can penetrate two opposite surfaces (e.g., the upper surface and the lower surface) of the specimen. In some embodiments, the center line of the through hole 21 may coincide with the center line of the specimen 2, that is, the through hole 21 is positioned at the center of the specimen 2, based on which the specimen 2 connected in series on the hanger 13 can remain relatively stable.

[0053] In some embodiments, the through hole 21 may be a bare hole (i.e., no thread is provided thereon). In this case, if the test piece 2 is mounted on the straight section 132 only through the through hole 21, the test piece 2 will fall due to gravity. To prevent the test piece from falling, the straight section 132 may be provided with a stopper 138 at its end. Here, the "end" refers to the end of the straight section 132 close to the bottom of the water boiling tank 11. After the last test piece 2 is connected in series to the straight section 132, the stopper 138 is connected to the end of the straight section 132, so as to prevent the test piece 2 from falling. The stopper 138 may be a fastener such as a nut, and accordingly, the straight section 132 may have a thread at the end, based on which the two can be connected by threaded cooperation.

[0054] According to the boiling test system provided by the utility model, when performing a boiling test, the following assembly steps can be performed: the holding component is placed inside the boiling box, and then a preset number of test pieces are connected to the hanging piece according to needs, for example, 10 products of the same kind made of the same material (such as plastic) are connected to the second end of the hanging piece in sequence, and then the first end of the hanging piece is connected to the holding component, so that the test pieces connected to the hanging piece will be suspended inside the boiling box, which is convenient for subsequent boiling tests.

[0055] By using the boiling test system of the utility model, the tester can set a suitable number of hanging parts according to actual needs and arrange a corresponding number of test pieces on each hanging part. In this way, the internal space of the boiling box in the height direction is fully utilized, and a large number of test pieces can be arranged inside the boiling box at one time, thereby improving the test efficiency.

[0056] Furthermore, the test pieces are suspended inside the water boiling box by means of the suspension parts, so that they will not be heated unevenly, and there will be no accumulation between the test pieces, thereby ensuring the accuracy of the test. Specifically, on the one hand, for multiple test pieces, these test pieces are suspended inside the water boiling box by means of the suspension parts. Since their environmental conditions such as temperature in the height direction of the water boiling box are basically the same, the consistency of the state (temperature, etc.) of the multiple test pieces in the water boiling box during the test is ensured, thereby ensuring the accuracy of the test results; on the other hand, for a single test piece, the suspended test piece basically does not have a large area of ​​contact with other parts, thereby ensuring that each part of the test piece can be heated evenly during the test, thereby ensuring the accuracy of the test results. More accurate test results help to screen more suitable material types and / or improve materials more reasonably.

[0057] In addition, since the hanging member is simply hooked on the holding assembly and one end of the hanging member is located at the upper part of the water boiling tank and exposed to the liquid in the water boiling tank, during the test, the hanging member can be removed from the holding assembly and the test piece can be removed from the hanging member to conveniently take samples at different time periods. In addition, after the test is finished, when the test tools are sorted out, the hanging member with the test piece suspended thereon can be conveniently removed from the water boiling tank as a whole by, for example, manual labor.

[0058] Here, an exemplary embodiment of the boiling test system according to the utility model has been described in detail, but it should be understood that the utility model is not limited to the specific embodiments described and shown in detail above. Those skilled in the art will easily think of other embodiments of the utility model after considering the specification and practicing the utility model disclosed herein.
