Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling technology, and in particular to a positioning telescopic sampler. Background Technology
[0002] 107 adhesive (α,ω-dihydroxy polysiloxane) is a basic raw material for high-performance sealants widely used in construction, automotive manufacturing, and electronic packaging. Its physicochemical properties directly affect the quality of the final product. Therefore, during production and use, 107 adhesive needs to be sampled and tested regularly to ensure its performance meets process requirements. Currently, the industry mostly uses manual sampling, where operators use simple tools (such as scrapers) to extract samples from containers. However, this traditional sampling method has many limitations, affecting the efficiency and accuracy of sampling and testing. First, it is impossible to accurately control the sample volume, and sample spillage and contamination are prone to occur during the sampling process. Moreover, sampling 107 adhesive from containers at different depths is inconvenient, making it difficult to achieve precise point sampling, resulting in insufficient sample representativeness and errors in test results. Therefore, there is an urgent need for a new type of 107 adhesive sampler that can solve the above problems. Utility Model Content

[0004] To achieve the above objectives, this utility model provides a slot-positioning telescopic sampler, comprising:
[0005] The sampling body includes a sampling tube and a sleeve. The sleeve is fitted around the outer periphery of the sampling tube so that the sampling tube can move relative to the sleeve along its own axis to adjust the length of the sampling body.
[0006] A suction element is slidably disposed inside the sampling tube;
[0007] A sampling rod, at least part of which is inserted into the sampling tube, includes a first push-pull rod and a second push-pull rod. The first end of the first push-pull rod is connected to the suction member, and the second end of the first push-pull rod is inserted into the second push-pull rod so that the second push-pull rod can move relative to the first push-pull rod along its own axis to adjust the length of the sampling rod.
[0008] A sampling head is connected to the first end of the sampling tube, and the sampling head has a sampling port that is connected to the sampling tube.
[0009] In one embodiment, the first push-pull rod has a first pressing protrusion that can protrude from or be recessed into the outer peripheral surface of the first push-pull rod. The first pressing protrusion is disposed at the second end of the first push-pull rod. The second push-pull rod has a plurality of first locking holes spaced apart along its own axial direction. The opening direction of the first locking holes is intersected with the circumferential direction of the second push-pull rod. The first pressing protrusion can pass through the first locking holes so that the length of the sampling rod can be adjusted or fixed.
[0010] In one embodiment, the sampling tube has a second pressing protrusion that can protrude from or be recessed into the outer peripheral surface of the sampling tube. The second pressing protrusion is located at one end of the sampling tube away from the sampling head. The sleeve has a plurality of second locking holes spaced apart along its own axial direction. The opening direction of the second locking holes is intersected with the axial direction of the sleeve. The second pressing protrusion can pass through the second locking holes so that the length of the sampling body can be adjusted or fixed.
[0011] In one embodiment, the sleeve has multiple rows of second locking holes, with multiple second locking holes in each row arranged at intervals along the axial direction of the sleeve and multiple rows of second locking holes arranged at intervals along the outer circumferential direction of the sleeve. The number of second pressing protrusions is multiple, and multiple second pressing protrusions are arranged at intervals along the outer circumferential side of the sampling tube. Each row of second locking holes corresponds to one second pressing protrusion.
[0012] In one embodiment, the sampling head is configured as a cone, and the sampling port is located at the tip of the cone of the sampling head.
[0013] In one embodiment, the sampling rod further includes a handle, which is disposed at the end of the second push-pull rod opposite to the suction member.

[0015] In one embodiment, the sampling tube has a scale that extends axially along the sampling tube.
[0016] In one embodiment, the sampling body further includes a guide cover, which is disposed at the second end of the sampling tube. The guide cover has a guide hole that communicates with the sampling tube, and the sampling rod passes through the guide hole.
[0017] In one embodiment, the sampling head is detachably connected to the sampling rod.
[0018] The above-mentioned solution of this utility model has the following beneficial effects:
[0019] In this embodiment, the pressure rod body is configured as a groove shape, the sampling tube and the sleeve are interlocked, and the sampling tube can move relative to the sleeve along its own axis, so that the overall length of the sampling body can be adjusted. This allows the telescopic sampler to adjust the length of the sampling body according to the sampling environment and sampling depth to adapt to various complex sampling scenarios. Whether sampling 107 glue from the bottom of a large storage container or collecting 107 glue samples from a distance, it can be completed relatively easily, effectively improving the flexibility and applicability of sampling. The first push-pull rod and the second push-pull rod are interlocked, and the first push-pull rod can move relative to the second push-pull rod along its own axis, so that the overall length of the sampling rod can be adjusted. This allows the sampling rod to adjust its own length according to the length of the sampling body, ensuring that a portion of the sampling rod remains outside the sampling body, facilitating the movement of the suction component within the sampling tube to draw fluid.
[0020] Other beneficial effects of this invention will be described in detail in the following detailed description section. Attached Figure Description

Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0027] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model 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 utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a locking 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 of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] This application provides a card slot telescopic sampler for drawing fluids such as adhesive and water, for example, 107 adhesive. Specifically, please refer to... Figure 1 and Figure 3 The telescopic sampler includes a sampling body 1, a suction component 2, a sampling rod 3, and a sampling head 4.
[0030] The sampling body 1, serving as the main body for holding the fluid after it has been drawn in, can be made of a material with sufficient strength and rigidity, such as plastic or metal. The sampling body 1 can be configured as follows: Figure 1 and Figure 2 The cylinder shown can also be configured as a square prism. The sampling body 1 includes a sampling tube 11 and a sleeve 12. The sleeve 12 is fitted around the outer periphery of the sampling tube 11 so that the sampling tube 11 can move relative to the sleeve 12 along its own axial direction to adjust the length of the sampling body 1. For example, please refer to... Figure 1 and Figure 2 , Figure 1The sampling tube 11 and the sleeve 12 are shown to be almost completely overlapped. Figure 2 The diagram shows the sampling tube 11 and sleeve 12 moving away from each other along the axial direction of the sampling tube 11. When the sampling tube 11 and sleeve 12 move closer together along the axial direction of the sampling tube 11, the overall length of the sampling body 1 gradually decreases. When the sampling tube 11 and sleeve 12 move away from each other along the axial direction of the sampling tube 11, the overall length of the sampling body 1 gradually increases. The longer sampling body 1 allows the clamping telescopic sampler of this application to draw fluid to deeper depths. For example, the frictional force between the sampling tube 11 and sleeve 12 is large enough to prevent relative movement between the sampling tube 11 and sleeve 12 during the sampling process.
[0031] Please see Figure 3 The suction element 2 is slidably disposed within the sampling tube 11. For example, when the suction element 2 slides within the sampling tube 11, fluid can enter the sampling tube 11 under atmospheric pressure to complete sampling. For example, the suction element 2 can be a piston, which includes a suction body and a rubber sealing ring. The rubber sealing ring surrounds the outer periphery of the suction body and abuts against the inner wall of the sampling tube 11, allowing the piston to be slidably disposed within the sampling tube 11 in a sealing manner, thereby making the suction of fluid by the telescopic sampler smoother.
[0032] At least a portion of the sampling rod 3 is inserted into the sampling tube 11. For example, please refer to... Figure 3 A portion of the sampling rod 3 is inserted axially into the sampling tube 11 and connected to the suction member 2, while another portion of the sampling rod 3 is located outside the sampling tube 11. For example, the sampling rod 3 can be made of a material with sufficient strength and rigidity, such as plastic or metal. Pushing or pulling the portion of the sampling rod 3 outside the sampling tube 11 allows the suction member 2 to move back and forth within the sampling tube 11. The sampling rod 3 includes a first push-pull rod 31 and a second push-pull rod 32. The first end of the first push-pull rod 31 is connected to the suction member 2, and the second end of the first push-pull rod 31 is inserted into the second push-pull rod 32, allowing the second push-pull rod 32 to move axially relative to the first push-pull rod 31 to adjust the length of the sampling rod 3. For example, please refer to [link to example]. Figure 3 , Figure 3 The diagram shows the first push-pull rod 31 and the second push-pull rod 32 moving away from each other along the axial direction of the first push-pull rod 31. When the first push-pull rod 31 and the second push-pull rod 32 move closer together along the axial direction of the first push-pull rod 31, the overall length of the sampling rod 3 gradually decreases. When the first push-pull rod 31 and the second push-pull rod 32 move away from each other along the axial direction of the first push-pull rod 31, the overall length of the sampling rod 3 gradually increases. Please refer to [link / reference]. Figure 2When the length of the sampling body 1 is relatively long, the longer sampling rod 3 can be adapted to the sampling body 1 so that part of the structure of the sampling rod 3 can be located outside the sampling body 1, so as to facilitate the driving of the suction component 2 to move inside the sampling tube 11. For example, the friction between the first push-pull rod 31 and the second push-pull rod 32 is large enough to prevent relative movement between the first push-pull rod 31 and the second push-pull rod 32 during the sampling process of the locking telescopic sampler.
[0033] Please see Figure 1 and Figure 2 The sampling head 4 is connected to the first end of the sampling tube 11. The sampling head 4 has a sampling port 41, which is connected to the sampling tube 11 so that the fluid around the retractable sampler can enter the sampling tube 11 through the sampling port 41. For example, the material of the sampling head 4 can be a material with a certain strength and rigidity, such as plastic or metal.
[0034] In this embodiment, the sampling tube 11 and the sleeve 12 are sleeved together, and the sampling tube 11 can move relative to the sleeve 12 along its own axis, so that the overall length of the sampling body 1 can be adjusted. This allows the telescopic sampler to adjust the length of the sampling body 1 according to the sampling environment and sampling depth, adapting to various complex sampling scenarios. Whether sampling 107 glue from the bottom of a large storage container or collecting 107 glue samples from a distance, it can be completed relatively easily, effectively improving the flexibility and applicability of sampling. The first push-pull rod 31 and the second push-pull rod 32 are sleeved together, and the first push-pull rod 31 can move relative to the second push-pull rod 32 along its own axis, so that the overall length of the sampling rod 3 can be adjusted. This allows the sampling rod 3 to adjust its own length according to the length of the sampling body 1, ensuring that a portion of the sampling rod 3 remains outside the sampling body 1, facilitating the movement of the suction component 2 within the sampling tube 11 to suction fluid.
[0035] In one embodiment, please refer to Figure 3The first push-pull rod 31 has a first pressing protrusion 311, which can protrude from or be recessed into the outer peripheral surface of the first push-pull rod 31. For example, the first pressing protrusion 311 can be a spring button. The first pressing protrusion 311 is disposed at the second end of the first push-pull rod 31, that is, the first pressing protrusion 311 is located at the end of the first push-pull rod 31, so that the sampling rod 3 can have the maximum length. The second push-pull rod 32 has a plurality of first locking holes 321 arranged at intervals along its own axial direction. The opening direction of the first locking holes 321 is intersected with the circumferential direction of the second push-pull rod 32. The first pressing protrusion 311 can pass through the first locking hole 321 so that the length of the sampling rod 3 can be adjusted or fixed. Through the locking engagement of the first pressing protrusion 311 and the first locking hole 321, the movement of the first push-pull rod 31 relative to the second push-pull rod 32 along its own axial direction is restricted. When the first pressing protrusion 311 passes through different first locking holes 321, the length of the sampling rod 3 can be adjusted and fixed. By reasonably arranging the spacing between adjacent first locking holes 321, the required and fixed length of the sampling rod 3 can be obtained, so as to effectively avoid changes in the relative displacement of the first push-pull rod 31 and the second push-pull rod 32 during the sampling process while facilitating the movement of the suction component 2, thus facilitating sampling.
[0036] For example, a first pressing protrusion 311 is provided at one end of the first push-pull rod 31 near the second push-pull rod 32, and a first locking hole 321 is provided at one end of the second push-pull rod 32 near the first push-pull rod 31, so that the sampling rod 3 has the maximum length.
[0037] In one embodiment, please refer to Figure 2The sampling tube 11 has a second pressing protrusion 111, which can protrude from or be recessed into the outer peripheral surface of the sampling tube 11. For example, the second pressing protrusion 111 can be a spring button. The second pressing protrusion 111 is located at the end of the sampling tube 11 opposite to the sampling head 4, that is, the second pressing protrusion 111 is located at the end of the sampling tube 11, so that the sampling body 1 can have the maximum length. The sleeve 12 has a plurality of second locking holes 121 arranged at intervals along its own axial direction. The opening direction of the second locking holes 121 is intersected with the axial direction of the sleeve 12. The second pressing protrusion 111 can pass through the second locking holes 121 so that the length of the sampling body 1 can be adjusted or fixed. Through the locking engagement of the second pressing protrusion 111 and the second locking holes 121, the movement of the sampling tube 11 relative to the sleeve 12 along its own axial direction is restricted. When the second pressing protrusion 111 passes through different second locking holes 121, the length of the sampling body 1 can be adjusted and fixed. By reasonably arranging the spacing between adjacent second locking holes 121, the required and fixed length of the sampling body 1 can be obtained. This effectively avoids deviations in the position of the sampling head 4 caused by changes in the relative position of the sampling tube 11 and the sleeve 12 during the sampling process of the locking telescopic sampler. This helps to improve the reliability of the sampling results, making the test data of 107 glue more accurate and improving the level of product quality control.
[0038] In one embodiment, please refer to Figure 1 and Figure 2 The sleeve 12 has multiple rows of second locking holes 121, with multiple second locking holes 121 in each row arranged at intervals along the axial direction of the sleeve 12 and at intervals along the outer circumference of the sleeve 12. For example, the sleeve 12 has two rows of second locking holes 121, which are evenly spaced along the outer circumference of the sleeve 12. Each row has five second locking holes 121, and the five second locking holes 121 in each row are evenly spaced along the circumference of the sleeve 12. There are multiple second pressing protrusions 111, which are arranged at intervals along the outer periphery of the sampling tube 11. Each row of second locking holes 121 corresponds to one second pressing protrusion 111, so that multiple second pressing protrusions 111 can pass through the second locking holes 121 located in different rows. This allows the sampling tube 11 and the sleeve 12 to have multiple points in their circumferential direction that restrict their relative movement along their own axial direction. This allows for better adjustment and fixation of the length of the sampling body 1, and more effectively avoids deviation of the sampling head 4 due to changes in the relative position of the sampling tube 11 and the sleeve 12 during the sampling process. This is beneficial to improving the reliability of the sampling results, making the test data of 107 glue more accurate, and improving the control level of product quality.
[0039] In one embodiment, please refer to Figures 1-3The sampling head 4 is configured as a cone shape, and the sampling port 41 is located at the tip of the cone of the sampling head 4. This helps to reduce the fluid adhering to the wall and spilling during the sampling process, thereby reducing the possibility of sample contamination and improving the accuracy and purity of sampling.
[0040] In one embodiment, please refer to Figures 1-3 The sampling rod 3 also includes a handle 33, which is located at the end of the second push-pull rod 32 away from the suction member 2. The handle 33 can be gripped well so that the sampling personnel can push and pull the sampling rod 3, thereby driving the suction member 2 to move in the sampling tube 11 to draw fluid.
[0041] In one embodiment, the sampling body 1 is configured as a transparent structure to facilitate real-time observation of the sampling process.
[0042] In one embodiment, please refer to Figure 2 and Figure 3 The sampling tube 11 has a scale 112, which extends along the axial direction of the sampling tube 11. The scale 112 can intuitively reflect the volume of the aspirated fluid, making it easier for the sampler to accurately control the volume of the sample taken. For example, the accuracy of the scale 112 can be accurate to milliliters.
[0043] In one embodiment, please refer to Figures 1-3 The sampling body 1 also includes a guide cover 13, which is located at the second end of the sampling tube 11, for example, the end opposite to the sampling head 4. The guide cover 13 has a guide hole 131, which is connected to the sampling tube 11. The sampling rod 3 passes through the guide hole 131, so that the sampling rod 3 can only move relative to the sampling body 1 along the opening direction of the guide hole 131 during the movement relative to the sampling body 1. This helps to standardize the movement path of the sampling rod 3 and improve the success rate of the clamping telescopic sampler in drawing samples.
[0044] In one embodiment, the sampling head 4 and the sampling rod 3 are detachably connected, allowing the positioning telescopic sampler of this application to be disassembled more thoroughly. This enables each component of the positioning telescopic sampler to be thoroughly cleaned, removing fluid residue. This helps reduce the possibility of reduced accuracy of the scale 112 or jamming of the suction component 2 due to fluid adhering inside the positioning telescopic sampler, thereby improving the accuracy of resampling and providing a more reliable test data basis for subsequent work. It is understood that the sampling tube 11, sleeve 12, and guide cover 13 of this application are all detachably connected, and the suction component 2 and sampling rod 3 can also be detached from the sampling tube 11.
[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
