Description

Technical Field

[0001] This utility model relates to the field of epoxy resin finished product testing technology, specifically a sampling device for testing epoxy resin finished products. Background Technology

[0002] In the production, processing, and application of epoxy resin, accurate and reliable testing of the finished product is a key step in ensuring product quality and performance. As an important thermosetting resin, epoxy resin has excellent physical and mechanical properties, electrical insulation properties, chemical stability, and good processing performance, and is widely used in many fields such as coatings, adhesives, electronics, and composite materials. However, the quality of epoxy resin products is affected by a variety of factors such as raw materials, production processes, and storage conditions. Therefore, it is essential to conduct regular or irregular sampling and testing.

[0003] When testing finished epoxy resin products, sampling devices are typically used to sample epoxy resin from different areas of the container. However, due to the large volume of some containers and the limited arm length of the testing personnel, sampling epoxy resin from distant areas is very inconvenient. Therefore, for example, patent CN217980892U provides a sampling device for testing finished epoxy resin products. This sampling device increases the overall length of the device by setting an extension mechanism and using its connecting arm to facilitate the testing personnel to sample epoxy resin from distant areas. The sampling device uses a motor to drive a piston to move, thereby sampling epoxy resin into the container. However, since the connecting arm of this sampling device has a fixed length, when sampling epoxy resin from small containers, the longer sampling device is actually inconvenient for sampling operations. Moreover, the longer sampling device is also inconvenient for testing personnel to carry. In addition, since this sampling device only has one container to hold the sample, during continuous sampling, some epoxy resin adhering to the sampling tube in the container will mix with the next batch of samples, resulting in inaccurate sample test results.

[0004] Therefore, we have designed a sampling device for testing epoxy resin finished products to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a sampling device for testing epoxy resin finished products, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sampling device for testing epoxy resin finished products, comprising a housing, the housing being cylindrical, an outlet being opened on the side of the housing, a tubular handle being installed at the outlet, an extension tube being threaded to the front end of the handle, a connecting tube being threaded to the front end of the extension tube, a fixing buckle being provided at the front of the connecting tube, a connecting rod being fixedly connected between the outer side of the connecting tube and the outer side of the fixing buckle, a detachable piston cylinder being installed on the fixing buckle, a piston being provided inside the piston cylinder, a piston rod being connected to the rear of the piston, and a threaded column being connected to the rear end of the piston rod;

[0007] A shaft is rotatably mounted between the two end faces inside the housing. A reel is mounted on the shaft. A crank is provided outside the housing. The crank is fixed to one end of the shaft. A steel wire rope is wound on the reel. One end of the steel wire rope is fixed to the reel. The other end of the steel wire rope is connected to a nut. The nut passes through a handle, an extension tube, and a connecting tube, and is connected to a threaded post by threads.

[0008] Preferably, the fixing buckle includes two semicircular rings, one end of which is rotatably connected by a hinge, and the other end of which is fitted with a buckle. The fixing buckle is wrapped around the outside of the piston cylinder by the two semicircular rings.

[0009] Preferably, two positioning rings are fixedly installed on the outside of the piston cylinder, with the two positioning rings located in front of and behind the fixing buckle, respectively.

[0010] Preferably, the piston cylinder has an inlet / outlet for epoxy resin to enter and exit, and a valve is installed on the inlet / outlet.

[0011] Preferably, the piston cylinder has an outlet at its rear end for removing the piston, and a cover is threadedly connected to the outlet. The cover has a through hole through which only the piston rod and the threaded post can pass.

[0012] Preferably, the front end of the grip and the front end of the extension tube are both provided with external threads, and the rear end of the connecting tube and the rear end of the extension tube are both provided with internal threads that can mate with their external threads.

[0013] Compared with the prior art, this utility model provides a sampling device for testing epoxy resin finished products, which has the following beneficial effects:

[0014] 1. The sampling device for epoxy resin finished product testing adopts a modular design. By increasing or decreasing the number of connected extension tubes, the overall length of the device can be adjusted to adapt to different working scenarios. By setting a crank to drive the reel to rotate and wind up the steel wire rope, the steel wire rope can pull the piston and piston rod to move backward, thereby drawing the epoxy resin into the piston cylinder through negative pressure.

[0015] 2. The sampling device for testing epoxy resin finished products is equipped with a detachable and replaceable piston cylinder. When performing continuous sampling, the piston cylinder can be quickly replaced to prevent the residual sample from the previous batch from mixing with the sample in the next batch, thereby improving the accuracy of the test results.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1: Please refer to Figures 1-6The sampling device includes a cylindrical housing 1 with a tubular handle 2 installed at an outlet on its side. The front end of the handle 2 is threadedly connected to an extension tube 3, which in turn is threadedly connected to a connecting tube 4. A fixing buckle 5 located directly in front of the connecting tube 4 consists of two semi-circular rings 51. One semi-circular ring 51 is connected to the connecting tube 4 via a connecting rod 6. One end of each semi-circular ring 51 is rotatably connected via a hinge, and the other end is connected via a latch 52. The two semi-circular rings 51 fit together to encircle the piston cylinder 7, thus securing the piston cylinder 7. By opening the latch 52 and flipping open the semi-circular rings 51, the piston cylinder 7 can be detached from the fixing buckle 5. Inside the piston cylinder 7 is a piston 8. The rear end of the piston 8... A piston rod 9 is connected to a threaded post 10 at its rear end. A reel 11 is fixed on a shaft rotatably mounted between the two end faces inside the housing 1. A crank 12 outside the housing 1 is connected to one end of the shaft. One end of a steel wire rope 13 wound on the reel 11 is fixed to the reel 11, and the other end is connected to a nut 14. The nut 14 passes through the handle 2, the extension tube 3, and the connecting tube 4 and is threadedly connected to the threaded post 10. The piston cylinder 7 has an inlet and outlet port and a valve 16 installed at its front end. In use, rotating the crank 12 drives the reel 11 to rotate, and the steel wire rope 13 pulls the nut 14 to move. This, in turn, pulls the piston rod 9 and the piston 8 to move inside the piston cylinder 7 through the threaded post 10, thereby drawing epoxy resin into the piston cylinder 7 and achieving epoxy resin sampling.

[0025] Example 2: Based on Example 1, the structure of the piston cylinder 7 is further optimized. Two positioning rings 15 are fixedly installed on the outside of the piston cylinder 7, located in front of and behind the fixing buckle 5 respectively. The positioning rings 15 can prevent the piston cylinder 7 from moving back and forth during the sampling process, thus improving the reliability of the sampling. At the same time, the rear end of the piston cylinder 7 is provided with an outlet and a cover 17 is connected by threads. The cover 17 has a through hole for the piston rod 9 and the threaded post 10 to pass through. The cover 17 can confine the piston 8 inside the piston cylinder 7. By removing the cover 17, the piston 8 inside the piston cylinder 7 can be taken out, which facilitates the cleaning and maintenance of the piston cylinder 7.

[0026] Example 3: When sampling epoxy resin, the number of extension tubes 3 can be increased or decreased according to the volume of the storage container to adjust the overall length of the sampling device. For example, when the container storing epoxy resin is large, the testing personnel may not be able to sample epoxy resin from areas far away due to insufficient sampling device length. In this case, the overall length of the sampling device can be increased by increasing the number of connected extension tubes 3, thereby ensuring that epoxy resin can be sampled from all areas of the container. Conversely, when the container storing epoxy resin is small, an excessively long sampling device may be inconvenient for the testing personnel to perform sampling operations. At this point, the overall length of the sampling device can be reduced by decreasing the number of extension tubes 3 connected. In addition, if the sampling device is too long, it will be inconvenient for the testing personnel to carry. Therefore, the extension tubes 3 can be disassembled into sections to facilitate carrying by the testing personnel. Both the front end of the handle 2 and the front end of the extension tube 3 are provided with external threads, and both the rear end of the connecting tube 4 and the rear end of the extension tube 3 are provided with internal threads that can mate with their external threads. This design allows the front end of the handle 2 to be connected to the rear end of the extension tube 3 or the rear end of the connecting tube 4 by thread. The front end of the extension tube 3 can be connected to the rear end of the connecting tube 4 or the rear end of another extension tube 3 by thread.

[0027] Usage procedure: Before use, carefully check whether each part of the sampling device is intact, ensure that the threaded connection is not loose, the piston 8 can slide freely in the piston cylinder 7, and the valve 16 can be opened and closed flexibly. Then, according to the actual use needs, choose whether to increase or decrease the number of extension tubes 3 connected. Next, place the piston cylinder 7 inside the two semi-circular rings 51 of the fixing buckle 5 and lock the buckle 52. Finally, connect the nut 14 to the threaded post 10 at the rear end of the piston rod 9 through the thread.

[0028] In use, extend the piston cylinder 7 toward the epoxy resin in the area to be sampled, then rotate the crank 12. The crank 12 drives the coaxial reel 11 to rotate, causing the reel 11 to wind up the wire rope 13. The traction of the wire rope 13 pulls the piston 8 and piston rod 9 backward, thereby drawing the epoxy resin in the area to be tested into the piston cylinder 7 through the inlet and outlet ports on the piston cylinder 7. After sampling is completed, close the valve 16 on the piston cylinder 7, unscrew the nut 14 from the threaded post 10 of the piston cylinder 7, open the retaining buckle 5 and replace it with a new piston cylinder 7. Finally, close the retaining buckle 5 and connect the nut 14 to the threaded post 10 of the new piston cylinder 7, and move to the next area to be tested for sampling.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
