Description

Technical Field

[0001] This utility model relates to the fields of biology and medical technology; more specifically, it relates to a sample extraction device. Background Technology

[0002] The field of biology and medical technology refers to forestry pest monitoring and survey work. By using biological knowledge and technical means, it identifies, monitors the occurrence and development of pests in forestry ecosystems, and conducts comprehensive surveys to formulate effective prevention and control measures to protect the balance and stability of forest resources and the ecological environment. A sample extraction device is commonly used in the field of biology and medical technology. It is a device used to collect, separate and obtain specific samples from various sources and is widely used in many fields such as medicine, biology, environmental science, food testing, and industrial quality control.

[0003] Currently, existing extraction devices are prone to slippage and displacement during use, which reduces their safety and stability. Furthermore, these devices are not designed for different sample extraction heights, requiring users to carry devices of varying extraction lengths when extracting multiple samples, thus limiting their applicability and flexibility. Therefore, a new sample extraction device is urgently needed to address these issues. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a sample extraction device to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a sample extraction device, including a test tube:

[0006] The test tube is equipped with a telescopic rod that slides inside, and a piston is provided at the lower end of the telescopic rod. A connecting tube is fixed at the lower end of the test tube, and an adjusting tube is fixed at the lower end of the connecting tube. An adjusting tube is slidably inserted inside the adjusting tube, and a support pad is fixed at the lower end of the adjusting tube.

[0007] Preferably, the surface of the test tube is provided with graduation lines, which, when used in conjunction with the graduation lines, allow for real-time monitoring of the amount of sample extracted by the device.

[0008] Preferably, the diameter of the upper surface of the telescopic rod is larger than the diameter of the upper surface of the test tube. The use of the telescopic rod makes the equipment more convenient to use.

[0009] Preferably, the upper end of the test tube is provided with a dustproof pad, and the dustproof pad is made of rubber. This design can prevent dust from falling in when the equipment is not in use.

[0010] Preferably, the upper end of the test tube is fixed with a support plate twice, and both the upper and lower ends of the support plate are provided with anti-slip pads. When the user's hand is in contact with the surface of the anti-slip pad, the friction between the device and the user's contact surface can be increased, thereby preventing the device from falling during use.

[0011] Preferably, a hanging plate is fixed to the upper end of one side of the test tube, and the hanging plate is inverted U-shaped. This design makes it more convenient to hang the equipment.

[0012] Preferably, the support pad is made of silicone. The use of silicone can increase friction between the device and the edge of the extract when extracting samples, thereby improving the stability and accuracy of the extraction process.

[0013] The technical effects and advantages of this utility model are as follows: By placing the hand position against the upper and lower surfaces of the support plate, and then moving the telescopic rod upward, the piston drives the sample upward to be extracted. At this time, the user can observe the amount of sample extracted by cooperating with the scale. Through the above operation, the device can be effectively prevented from slipping from the hand, thereby improving the safety and stability of the operation.

[0014] By rotating the adjustment tube at the lower end of the adjustment cylinder, the extraction height of the device can be changed according to different layers of the sample. This avoids the need for users to carry devices of different lengths when extracting samples of different heights, thereby improving the applicability and flexibility of the device.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The biology and medicine involved in this utility model are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1

[0022] like Figures 1 to 3 As shown, this embodiment proposes a sample extraction device, including a test tube 1, a telescopic rod 2 slidably inserted inside the test tube 1, and a piston 3 at the lower end of the telescopic rod 2. The surface of the test tube 1 is provided with scale lines. The diameter of the upper end surface of the telescopic rod 2 is larger than the diameter of the upper end surface of the test tube 1. A dustproof pad 4 is provided at the upper end of the test tube 1, and the dustproof pad 4 is made of rubber. Support plates 5 are fixed on both sides of the upper end of the test tube 1, and anti-slip pads are provided at both the upper and lower ends of the support plates 5. A hanging plate 6 is fixed on the upper side of one side of the test tube 1, and the hanging plate 6 is inverted U-shaped.

[0023] In this embodiment, the combination of test tube 1, telescopic rod 2, and piston 3 enables rapid sample extraction, thereby improving the convenience of the equipment. The use of scale lines allows users to better observe the amount of sample extracted. The use of dustproof pad 4 prevents dust from falling into the equipment during use and allows it to fit against the upper surface of telescopic rod 2. The use of support plate 5 and anti-slip pad prevents the equipment from shifting or slipping when it is in contact with the user's palm, thereby improving the service life of the equipment.

[0024] Example 2

[0025] like Figure 4 As shown, based on the same concept as the above embodiment, this embodiment also proposes: a connecting tube 7 is fixed at the lower end of the test tube tube 1, and an adjusting tube 8 is fixed at the lower end of the connecting tube 7. An adjusting tube 9 is slidably inserted inside the adjusting tube 8, and a support pad 10 is fixed at the lower end of the adjusting tube 9. The material of the support pad 10 is silicone.

[0026] In this embodiment, the use of the connecting tube 7 allows for better absorption of the sample, thereby accelerating the use of the equipment. By rotating the adjusting tube 9 inside the adjusting tube 8, the extension and retraction length of the adjusting tube 9 can be changed and adjusted according to the actual use or the extraction height of different samples, thereby improving the flexibility and efficiency of the equipment. The use of the support pad 10 can improve the stability and accuracy of the equipment.

[0027] Working principle: When using the equipment, first move the equipment to a suitable position, then rotate the adjusting tube 9 at the lower end of the adjusting cylinder 8, then align the lower surface of the support pad 10 with the surface around the sample, then align your hand with the upper and lower surfaces of the support plate 5, and move the telescopic rod 2 upward. At this time, the piston 3 will drive the sample upward to be extracted. The user can then observe and record the amount of sample extracted through the scale lines on the surface of the test tube cylinder 1. This is the complete working principle of this practical device.

[0028] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
