TECHNICAL FIELD
[0001] The application belongs to the technical field of detection, and particularly relates to a conveying pipeline assembly and a detection device. BACKGROUND
[0002] The detection device is used for detecting components of a sample, and comprises a detection main body and a conveying pipeline. The conveying pipeline is inserted on the detection main body and used for conveying the sample to the detection main body. In order to prevent the conveying pipeline from being separated from the detection main body, a connecting assembly used for connecting with the detection main body is often arranged on the conveying pipeline, and the connecting assembly can limit the conveying pipeline from moving in a direction away from the detection main body. In addition, in order to achieve a preheating effect of the sample before entering the detection main body, a heating module is arranged on the conveying pipeline to preheat the sample flowing through the conveying pipeline.
[0003] In the related art, in order to facilitate disassembly and assembly of the conveying pipeline and the detection main body, a certain gap is required to be left between the connecting assembly and the heating module to leave a space for movement of the connecting assembly. Thus, a part of the conveying pipeline between the connecting assembly and the heating module is exposed. When the conveying pipeline and the detection main body are disassembled and assembled or subjected to other external forces, the part of the conveying pipeline between the connecting assembly and the heating module is prone to bending. After the part of the conveying pipeline between the connecting assembly and the heating module is bent, on one hand, the conveying efficiency of the sample is affected, and on the other hand, the service life of the conveying pipeline is reduced. CONTENT OF THE UTILITY MODEL
[0004] The purpose of the embodiments of the application is to provide a conveying pipeline assembly and a detection device, which can solve the problem that a part of the conveying pipeline between the connecting seat and the heating module is prone to bending in the related art.
[0005] In a first aspect, the embodiments of the application provide a conveying pipeline assembly, comprising:
[0006] The conveying pipeline comprises a first pipeline and a second pipeline in communication with the first pipeline. The second pipeline is used for being in communication with a detection main body of a detection device.
[0007] The heating module is arranged on the first pipeline.
[0008] The connecting assembly is used for connecting the detection main body and the second pipeline respectively.
[0009] The pipeline protection member is sleeved on a part of the second pipeline. At least a part of the pipeline protection member is located between the connecting assembly and the heating module. The pipeline protection member is in sliding connection with at least one of the heating module and the connecting assembly. In a direction perpendicular to an axial direction of the second pipeline, the pipeline protection member is in limiting cooperation with the second pipeline.
[0010] In a second aspect, the embodiments of the present application further provide a detection device, comprising a detection main body and the above-mentioned conveying pipeline assembly, a second pipeline of the conveying pipeline assembly is in communication with the detection main body, and the connecting assembly is connected with the detection main body.
[0011] In the embodiments of the present application, the pipeline protection member is sleeved on part of the second pipeline, which can protect the second pipeline, so that the second pipeline is not easy to be bent directly by external force, and the pipeline protection member is limitedly matched with the second pipeline in the direction perpendicular to the axial direction of the second pipeline, so that when the second pipeline is subjected to the force of the connecting assembly, the pipeline protection member can limit the second pipeline, thereby ensuring that the second pipeline is not easy to be bent.
[0012] In addition, the pipeline protection member is slidingly connected with at least one of the heating module and the connecting assembly, which ensures that a space is left between the connecting assembly and the heating module for movement of the connecting assembly, so that the pipeline protection member is not easy to hinder the movement of the connecting assembly, thereby meeting the requirement of facilitating disassembly and assembly of the conveying pipeline and the detection main body. At the same time, through the sliding connection of the pipeline protection member with the heating module and / or the connecting assembly, the external force received by the pipeline protection member can be transmitted to the heating module and / or the connecting assembly, thereby being conducive to ensuring the strength of the pipeline protection member, so that the pipeline protection member is not easy to be deformed under stress, thereby improving the protection effect of the pipeline protection member on the second pipeline.

[0027] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.
[0028] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a class, not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in a "or" relationship.
[0029] The conveying pipeline assembly and the detection device provided by the embodiments of the present application will be described in detail below in combination with the drawings and specific embodiments and application scenarios.
[0030] Reference Figures 1-7 The conveying pipeline assembly provided by the embodiments of the present application can include a conveying pipeline 200, a heating module 300, a connecting assembly 400, and a pipeline protection piece 500.
[0031] As shown in Figure 2 The conveying pipeline 200 can include a first pipeline 210 and a second pipeline 220 in communication with the first pipeline 210, and the second pipeline 220 can be used to communicate with the detection main body 100 of the detection device, so as to be able to convey the sample into the detection main body 100.
[0032] The heating module 300 can be arranged on the first pipeline 210, so as to be able to preheat the sample flowing through the first pipeline 210. The connecting assembly 400 can be used to connect the second pipeline 220 and the detection main body 100 respectively, so as to connect the detection main body 100 and the second pipeline 220, and then make the detection main body 100 and the second pipeline 220 form a fixed connection.
[0033] The pipeline protection piece 500 can be sleeved on part of the second pipeline 220, so as to protect the second pipeline 220 and prevent the second pipeline 220 from being directly subjected to external force and being bent. At least part of the pipeline protection piece 500 can be located between the connecting assembly 400 and the heating module 300, so that the pipeline protection piece 500 can protect the exposed pipeline between the connecting assembly 400 and the heating module 300. In the direction perpendicular to the axial direction of the second pipeline 220, the pipeline protection piece 500 can be limited in cooperation with the second pipeline 220. In this way, when the second pipeline 220 is subjected to the action force of the connecting assembly 400, the pipeline protection piece 500 can limit the second pipeline 220, thereby preventing the second pipeline 220 from deforming in the direction perpendicular to the axial direction of the second pipeline 220, so as to ensure that the second pipeline 220 is not easy to be bent.
[0034] In addition, the pipeline protection piece 500 can be in sliding connection with at least one of the heating module 300 and the connecting assembly 400. This arrangement ensures that a space is left between the connecting assembly 400 and the heating module 300 for the movement of the connecting assembly 400, so that the pipeline protection piece 500 is not easy to hinder the movement of the connecting assembly 400, thereby meeting the requirement of facilitating the disassembly and assembly of the conveying pipeline 200 and the detection main body 100. At the same time, through the sliding connection of the pipeline protection piece 500 with the heating module 300 and / or the connecting assembly 400, the external force received by the pipeline protection piece 500 can be transmitted to the heating module 300 and / or the connecting assembly 400, thereby facilitating the guarantee of the strength of the pipeline protection piece 500, preventing the pipeline protection piece 500 from being deformed under stress, thereby improving the protection effect of the pipeline protection piece 500 on the second pipeline 220, and the pipeline protection piece 500 has a simple structure and is easy to process.
[0035] In one way, the pipeline protection piece 500 can be in sliding connection with the heating module 300, and the pipeline protection piece 500 is in fixed connection with the connecting assembly 400. For example, as shown in Figure 2As shown, the heating module 300 is provided with a guide hole 600, one end of the pipeline protection piece 500 is located in the guide hole 600, and the other end of the pipeline protection piece 500 is fixedly connected with the connecting assembly 400.
[0036] In another way, the pipeline protection piece 500 can be slidably connected with the connecting assembly 400, and the pipeline protection piece 500 is fixedly connected with the heating module 300. For example, Figure 6 As shown, the connecting assembly 400 is provided with a guide hole 600, one end of the pipeline protection piece 500 is located in the guide hole 600, and the other end of the pipeline protection piece 500 is fixedly connected with the heating module 300.
[0037] In yet another way, the pipeline protection piece 500 can be slidably connected with the heating module 300 and the connecting assembly 400 respectively. For example, Figure 7 As shown, the heating module 300 and the connecting assembly 400 can be provided with guide holes 600 respectively, and both ends of the pipeline protection piece 500 can be located in the guide holes 600 of the heating module 300 and the connecting assembly 400 respectively.
[0038] In an optional embodiment, as shown, Figure 2 The connecting assembly 400 can include a compression ring 430 and a connecting joint 410, a part of the connecting joint 410 is located in the insertion hole 110 and can be threadedly connected with the detection main body 100, the compression ring 430 can be fixedly sleeved on the second pipeline 220, and the compression ring 430 can be located in the insertion hole 110 and sealingly matched with the hole wall of the insertion hole 110. In this way, the connection sealing property of the second pipeline 220 and the detection main body 100 can be ensured.
[0039] In addition, in the direction from the connecting assembly 400 to the heating module 300, the compression ring 430 can be limitedly matched with the connecting joint 410, that is, in the direction from the connecting assembly 400 to the heating module 300, the connecting joint 410 can limit the compression ring 430 to prevent the compression ring 430 from moving outward, thereby preventing the second pipeline 220 from being pulled out of the insertion hole 110, so that the connection stability of the second pipeline 220 and the detection main body 100 can be improved.
[0040] The connecting assembly 400 can further include a fixing member 440 and a connecting seat 420, the connecting joint 410 can be used to connect with the detection main body 100, the fixing member 440 can be fixed to the outer wall of the second pipeline 220, and the connecting joint 410 and the connecting seat 420 can be sleeved on the second pipeline 220, that is, the second pipeline 220 can be inserted into the detection main body 100 through the connecting joint 410 and communicated with the detection main body 100. Moreover, part of the fixing member 440 can be located in the connecting joint 410, and the fixing member 440 can be limited and matched with the connecting seat 420 in the direction from the connecting assembly 400 to the heating module 300, that is, the connecting seat 420 can limit the fixing member 440 in the direction from the detection main body 100 to the heating module 300, so as to further prevent the second pipeline 220 from moving away from the detection main body 100 and separating from the detection main body 100.
[0041] Optionally, the connecting joint 410 and the connecting seat 420 are detachably connected, and the connecting joint 410 and the connecting seat 420 are detachably connected. When the detection main body 100 and the second pipeline 220 need to be disassembled, the connecting seat 420 can be moved away from the detection main body 100 to facilitate disassembly of the detection main body 100 and the second pipeline 220. Here, the connecting joint 410 and the connecting seat 420 can be threadedly connected, or the connecting joint 410 and the connecting seat 420 can be detachably connected by clamping or inserting, or by other means.
[0042] In the embodiment, as shown in Figure 4 The pipeline protection member 500 can be fixedly connected or slidingly connected with the connecting seat 420, and since the connecting seat 420 is sleeved on part of the second pipeline 220, the connecting seat 420 can limit part of the second pipeline 220 in the direction perpendicular to the axial direction of the second pipeline 220, so as to ensure the straightness of the second pipeline 220 to a certain extent, thereby achieving the effect of protecting the second pipeline 220.
[0043] In the optional embodiment, as shown in Figure 3 The heating module 300 can include a heating seat 310 and a heating cover plate 320 connected with the heating seat 310, and a heating space 301 can be formed between the heating seat 310 and the heating cover plate 320. The first pipeline 210 can be arranged in the heating space 301 in a bent manner, that is, the first pipeline 210 can include a plurality of sequentially connected bending portions, and the bending portions are located in the heating space 301. In this way, the heating area of the first pipeline 210 can be increased, thereby improving the preheating effect on the sample.
[0044] Optionally, the delivery pipeline 200 can further comprise a third pipeline 230, which can be in communication with one end of the first pipeline 210 away from the second pipeline 220, and the third pipeline 230 can be used to communicate with the sample storage device to facilitate the delivery of the sample to the detection main body 100.
[0045] Further optionally, in order to reduce the connection structure, the first pipeline 210, the second pipeline 220 and the third pipeline 230 can be an integrated structure.
[0046] In optional embodiments of the present application, one of the heating module 300 and the connection assembly 400 is in sliding connection with the pipeline protection piece 500, and the other is in fixed connection with the pipeline protection piece 500. In this way, not only is a space left between the connection assembly 400 and the heating assembly for the movement of the connection assembly 400, so that the pipeline protection piece 500 is less likely to hinder the movement of the connection assembly 400, but also the pipeline protection piece 500 can be fixed to prevent the pipeline protection piece 500 from moving randomly on the second pipeline 220.
[0047] In other embodiments, both the heating module 300 and the connection assembly 400 can also be in sliding connection with the pipeline protection piece 500.
[0048] In optional embodiments, as shown in Figure 2 One of the heating module 300 and the connection assembly 400 can be provided with a guide hole 600, which is coaxially arranged with the second pipeline 220, and part of the pipeline protection piece 500 is located in the guide hole 600. In this way, the pipeline protection piece 500 can be in sliding connection with the heating module 300 or the connection assembly 400, and the guide hole 600 can guide the pipeline protection piece 500 and prevent the pipeline protection piece 500 from being pressed against the second pipeline 220 when it moves. In addition, in the direction perpendicular to the axial direction of the second pipeline 220, the pipeline protection piece 500 can be limited by the hole wall of the guide hole 600. In this way, the hole wall of the guide hole 600 can provide stable support for the pipeline protection piece 500, so that it will not shake or displace in the direction perpendicular to the axial direction of the second pipeline 220, and thus the pipeline protection piece 500 is less likely to deform, thereby better protecting the second pipeline 220.
[0049] In other embodiments, neither the heating module 300 nor the connection assembly 400 can be provided with a guide hole 600.
[0050] Optionally, the guide hole 600 can be arranged on the heating module 300, and the pipeline protection piece 500 can be in fixed connection with the connection assembly 400. Since the size of the heating module 300 is larger than that of the connection assembly 400, it is relatively easy to arrange the guide hole 600 on the heating module 300, which is convenient for processing.
[0051] Of course, the guide hole 600 can also be arranged on the connecting assembly 400, and the pipeline protection member 500 can be fixedly connected with the heating module 300.
[0052] Further optionally, the pipeline protection member 500 and the connecting assembly 400 are in an integrated structure. In this way, the connection structure can be reduced, and when the pipeline protection member 500 is impacted by external force, the pipeline protection member 500 and the connecting assembly 400 can jointly resist the external force as a whole, reducing the phenomenon of local stress concentration, thereby reducing the possibility of damage of the pipeline protection member 500. Of course, the pipeline protection member 500 and the connecting assembly 400 can also not be in an integrated structure.
[0053] In an optional embodiment of the present application, the heating module 300 can be provided with a guide hole 600, one end of the pipeline protection member 500 is located in the guide hole 600, and the other end of the pipeline protection member 500 can be detachably connected with the connecting assembly 400; or the connecting assembly 400 can be provided with a guide hole 600, one end of the pipeline protection member 500 is located in the guide hole 600, and the other end of the pipeline protection member 500 can be detachably connected with the heating module 300. In this way, when the heating module 300, the connecting assembly 400 or the pipeline protection member 500 is damaged, the detachable connection mode facilitates the separation of the pipeline protection member 500 from the system, facilitating maintenance personnel to maintain or replace each component. Of course, one end of the pipeline protection member 500 can also be non-detachably connected with one of the heating module 300 and the connecting assembly 400.
[0054] In an optional embodiment, as shown in Figure 5 The pipeline protection member 500 can include a first support part 530 and a second support part 540, the first support part 530 and the second support part 540 are detachably connected, and the first support part 530 can be provided with a first support groove 5011, the second support part 540 can be provided with a second support groove 5012, the first support groove 5011 and the second support groove 5012 are in opposite connection to form a protection cavity 501 for accommodating part of the second pipeline 220, so as to protect the second pipeline 220. Here, the first support part 530 and the second support part 540 can be clamped or connected by screws.
[0055] One end of the first supporting part 530 and one end of the second supporting part 540 can be located in the guide hole 600, and the other end of the first supporting part 530 and the other end of the second supporting part 540 can be detachably connected with the other one of the heating module 300 and the connecting assembly 400. In this embodiment, since the first supporting part 530 and the second supporting part 540 are detachably connected, they can be placed in the guide hole 600 respectively before being docked and assembled during installation. Compared with the integral pipe protection piece 500, this split type installation method is more convenient, especially in the case of limited space or complex installation position, which can reduce the installation difficulty and improve the installation efficiency. Moreover, when the pipe protection piece 500 needs to be repaired or replaced, the first supporting part 530 and the second supporting part 540 can be easily detached, which is beneficial to save maintenance time and cost.
[0056] In other embodiments, the pipe protection piece 500 can also not include the first supporting part 530 and the second supporting part 540, for example, the pipe protection piece 500 can be an integral structure.
[0057] In optional embodiments, as shown in Figure 4 The pipe protection piece 500 can include a first protection part 510 and a second protection part 520 connected with the first protection part 510, the first protection part 510 can be in sliding connection with one of the heating module 300 and the connecting assembly 400, and the second protection part 520 can be in fixed connection with the other one of the heating module 300 and the connecting assembly 400. In the direction perpendicular to the axial direction of the second pipe 220, the cross-sectional area of the second protection part 520 is greater than that of the first protection part 510, that is, in the direction from the second pipe 220 to the pipe protection piece 500, that is, in the direction radially outward of the second pipe 220, the second protection part 520 protrudes from the first protection part 510. In this way, the connection area of the pipe protection piece 500 with the heating module 300 or the connecting assembly 400 can be increased, thereby the strength of the pipe protection piece 500 can be improved, and the thickness of part of the pipe protection piece 500 can be thickened, thereby the pipe protection piece 500 can have greater bending and torsional stiffness.
[0058] Of course, in the direction perpendicular to the axial direction of the second pipe 220, the cross-sectional area of the second protection part 520 can also be less than or equal to that of the first protection part 510.
[0059] In optional embodiments, the pipe protection piece 500 can include a plurality of limiting rods and an annular connecting part, the annular connecting part can be coaxially arranged with the second pipe 220, and each limiting rod can be connected with the annular connecting part to connect the limiting rods into an integral structure. Here, each limiting rod can be in sliding connection with at least one of the connecting assembly 400 and the heating module 300.
[0060] The plurality of limiting rods can be spaced apart along the circumference of the second pipeline 220, and each limiting rod is in limiting cooperation with the second pipeline 220 in the direction perpendicular to the axial direction of the second pipeline 220. In this way, each limiting rod can limit the second pipeline 220 in the direction perpendicular to the axial direction of the second pipeline 220 to prevent the second pipeline 220 from bending. In addition, the pipeline protection member 500 is provided in the form of a plurality of limiting rods, which can reduce the weight of the pipeline protection member 500 and save materials on the basis of limiting the second pipeline 220.
[0061] Of course, the pipeline protection member 500 can also have a tubular structure.
[0062] Based on the conveying pipeline assembly provided in the embodiments of the present application, the embodiments of the present application further provide a detection device. The detection device can include a detection main body 100 and the conveying pipeline assembly described in any of the above embodiments. The second pipeline 220 of the conveying pipeline assembly is in communication with the detection main body 100, and the connecting assembly 400 is connected to the detection main body 100.
[0063] The beneficial effects achieved by the detection device provided in the embodiments of the present application are consistent with the beneficial effects achieved by the conveying pipeline assembly provided in the embodiments of the present application, which will not be described here.
[0064] Optionally, the detection device can be a liquid phase column oven. The detection main body 100 can be a chromatographic column. Of course, the detection main body 100 can also be other structures that can achieve component detection.
[0065] The embodiments of the present application are described above in combination with the accompanying drawings, but the present application is not limited to the above specific embodiments. The above specific embodiments are only illustrative and not limiting. Those skilled in the art can make many forms under the inspiration of the present application without departing from the scope of the present application and the scope of protection of the claims.
