Description

Technical Field

[0001] This utility model relates to the field of sample collection equipment technology, specifically a sampling device for testing and detection. Background Technology

[0002] In existing technologies, when inspectors test liquid samples, they need to use a sampling device to take samples. After the sample is immersed in the sample and extracted, some sample will adhere to the outer wall of the sampling tube. When the sampling device moves, some of the sample attached to the sampling tube may drip into the working environment, thus contaminating the working environment and posing a certain safety hazard. Therefore, we propose a sampling device for testing and inspection. Utility Model Content

[0003] The purpose of this invention is to provide a sampling device for testing and inspection, which solves the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a sampling device for testing and inspection, comprising a sampling cylinder, a liquid extraction tube connected to the bottom end of the sampling cylinder, a piston slidably connected to the inner wall of the sampling cylinder, a pull rod fixedly installed at the top end of the piston, the pull rod movably passing through the top end of the sampling cylinder, a pull plate fixedly installed at the top end of the pull rod, and a protective mechanism provided below the liquid extraction tube;

[0005] The protective mechanism includes a hood, a connecting shaft, and a pull ring. A connecting frame is fixedly installed at the top of the hood. A rotating groove is opened at the bottom of the sampling cylinder. A shaft groove is opened on the inner wall of the rotating groove. The connecting shaft is inserted into the shaft groove. The top of the connecting frame is fixedly sleeved on the outer wall of the connecting shaft. A torsion spring is fixedly connected between the outer wall of the connecting shaft and the inner wall of the shaft groove. The pull ring is movably sleeved on the outer wall of the sampling cylinder. A fixing frame is fixedly installed on the outer wall of the sampling cylinder near the bottom. A guide roller is rotatably connected to the inner wall of the fixing frame through a bearing. A connecting rope is fixedly connected between the bottom of the pull ring and one side of the connecting frame. The connecting rope is in contact with the outer wall of the guide roller.

[0006] Preferably, the connecting frame is adapted to the rotating groove. By setting the rotating groove, the connecting frame can be limited, ensuring the stability of the connecting frame during use.

[0007] Preferably, a limiting slide plate is fixedly installed on the inner wall of the pull ring, and a second limiting groove is formed on the outer wall of the sampling cylinder. The limiting slide plate and the second limiting groove are slidably connected. By setting the limiting slide plate and the second limiting groove, the pull ring can be limited, ensuring the stability of the pull ring during use.

[0008] Preferably, a retaining plate is slidably connected to the top of the pull plate, and a retaining groove is provided on the outer wall of the sampling cylinder. The retaining plate is adapted to the retaining groove. By setting the retaining plate and the retaining groove, the retaining plate can limit the pull ring. This way, the personnel do not need to pull the pull ring continuously during the sample extraction process, which facilitates the operation.

[0009] Preferably, a limiting slider is fixedly installed at the bottom of the card plate, and a limiting groove is formed at the top of the pull ring. The limiting slider is slidably connected to the limiting groove. By setting the limiting slider and the limiting groove, the card plate can be fixedly slid on the pull ring.

[0010] Preferably, the limiting slider and the limiting groove are adapted to each other.

[0011] This utility model provides a sampling device for testing and inspection. This sampling device for testing and inspection has the following beneficial effects:

[0012] (1) The sampling device for testing and inspection, by setting a protective mechanism, can rotate the hood to the bottom of the sampling tube to collect the sample that may drip from the sampling tube, and avoid the sample from dripping into the working environment during the movement of the sampling tube, which would cause pollution to the environment. This solves the problem that after the sampling tube of the existing sampling device is immersed in the sample to extract the sample, some sample will adhere to the outer wall of the sampling tube. When the sampling device is moving, some sample attached to the sampling tube may drip into the working environment, thereby polluting the working environment and posing a certain safety hazard.

[0013] (2) The sampling device for testing and inspection is designed with a card plate and a card slot, so that the card plate can limit the pull ring. This means that the personnel do not need to keep pulling the pull ring during the sample extraction process, which makes it easier for personnel to operate. The structure is simple and the device is highly practical. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0023] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship 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. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1-7 As shown, this utility model provides a technical solution: a sampling device for testing and detection, including a sampling cylinder 1, a liquid extraction tube 2 connected to the bottom end of the sampling cylinder 1, a piston 3 slidably connected to the inner wall of the sampling cylinder 1, a pull rod 4 fixedly installed at the top end of the piston 3, the pull rod 4 movably passing through the top end of the sampling cylinder 1, a pull plate 10 fixedly installed at the top end of the pull rod 4, and a protective mechanism 5 provided below the liquid extraction tube 2;

[0026] The protective mechanism 5 includes a hood 501, a connecting shaft 504, and a pull ring 510. A connecting frame 502 is fixedly installed at the top of the hood 501. A rotating groove 503 is opened at the bottom of the sampling cylinder 1. A shaft groove 505 is opened on the inner wall of the rotating groove 503. The connecting shaft 504 is inserted into the shaft groove 505. The top of the connecting frame 502 is fixedly sleeved on the outer wall of the connecting shaft 504. A torsion spring 506 is fixedly connected between the outer wall of the connecting shaft 504 and the inner wall of the shaft groove 505. The pull ring 510 is movably sleeved on the outer wall of the sampling cylinder 1. A fixing frame 508 is fixedly installed on the outer wall of the sampling cylinder 1 near the bottom. A guide roller 509 is rotatably connected to the inner wall of the fixing frame 508 through a bearing. A connecting rope 507 is fixedly connected between the bottom of the pull ring 510 and one side of the connecting frame 502. The connecting rope 507 is in contact with the outer wall of the guide roller 509.

[0027] Specifically, in the above technical solution, when using the sampling device for testing and inspection, pulling the pull ring 510 upward causes the pull ring 510 to drive the connecting frame 502 to rotate upward via the connecting rope 507. The connecting frame 502 then drives the cover 501 to rotate upward, which in turn drives the connecting shaft 504 to rotate. The connecting shaft 504 then drives the torsion spring 506 to twist, ensuring that the cover 501 rotates upward and is not below the suction tube 2. Then, the locking plate 6 is pushed, causing it to engage in the locking groove 9, thus limiting and fixing the pull ring 510. At this point, the suction tube 2 can be immersed in the sample to be sampled. Then, pulling the pull plate 10 upward causes the pull rod 4 to move upward, which in turn moves the piston 3 upward, creating a negative pressure in the sampling cylinder 1, thereby drawing the sample into the sampling cylinder 1. When the sample is taken... After sampling, the sampling tube 2 is pulled away from the sample to be sampled. At this time, the clamping plate 6 can be pulled outward to disengage from the clamping groove 9. Then, the rotating shaft will drive the connecting frame 502 to rotate downward under the restoring force of the spring. The connecting frame 502 drives the cover 501 to rotate downward, so that the cover 501 rotates to below the sampling tube 2 to collect any sample that may drip from the sampling tube 2. This prevents the sample from dripping into the working environment during the movement of the sampling tube 1, thus avoiding environmental pollution. This solves the problem that in existing sampling devices, after the sampling tube 2 is immersed in the sample for extraction, some sample will adhere to the outer wall of the sampling tube 2. When the sampling device moves, some sample attached to the sampling tube 2 may drip into the working environment, thus polluting the working environment and posing a certain safety hazard.

[0028] Furthermore, the connecting bracket 502 is adapted to the rotating slot 503;

[0029] The rotating groove 503 can limit the position of the connecting frame 502, ensuring its stability during use.

[0030] Furthermore, a limiting slide plate 511 is fixedly installed on the inner wall of the pull ring 510, and a limiting groove 512 is opened on the outer wall of the sampling cylinder 1. The limiting slide plate 511 and the limiting groove 512 are slidably connected.

[0031] The limiting slide plate 511 and the limiting slide groove 512 can limit the pull ring 510 and ensure the stability of the pull ring 510 during use.

[0032] Furthermore, a clamping plate 6 is slidably connected to the top of the pull plate 10, and a groove 9 is provided on the outer wall of the sampling cylinder 1, with the clamping plate 6 and the groove 9 being adapted to each other.

[0033] By setting the card plate 6 and the card slot 9, the card plate 6 can limit the pull ring 510, so that the personnel do not need to keep pulling the pull ring 510 during the sample extraction process, thus making it easier for personnel to operate.

[0034] Furthermore, a limiting slider 7 is fixedly installed at the bottom of the card plate 6, and a limiting groove 8 is opened at the top of the pull ring 510, with the limiting slider 7 and the limiting groove 8 slidably connected.

[0035] By setting the limiting slider 7 and the limiting groove 8, the card plate 6 can be fixed and slid on the pull ring 510.

[0036] Furthermore, the limiting slider 7 is adapted to the limiting groove 8.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
