Description

Technical Field

[0001] The utility model relates to a sampling device for industrial waste oil treatment, belonging to the technical field of sampling devices. Background Art

[0002] The sampling device for industrial waste oil treatment is a device used to sample waste oil during industrial waste oil treatment. It is widely used in industrial waste oil treatment occasions. As people's demand for the use of sampling devices for industrial waste oil treatment has gradually increased, the existing sampling devices for industrial waste oil treatment can no longer meet people's needs. Therefore, a more convenient-to-use sampling device for industrial waste oil treatment is needed. After the sampling device for industrial waste oil treatment takes samples and stores them in a sample container, one end of the piston rod extends beyond the tube body. After being squeezed by external force, the sample will flow out of the tube body, which is very unstable during transportation. Therefore, the sample in the sampling tube needs to be moved to a container for storing the sample. The sampling device cannot be used directly as a sample container, which increases the sampling steps and thus reduces the sampling efficiency. Utility Model Content

[0003] The purpose of the utility model is to provide a sampling device for industrial waste oil treatment to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a sampling tube body, a sealing block is provided at one end of the sampling tube body, and a bottom plate is provided at one end of the sampling tube body, a piston rod is provided in the inner cavity of the sampling tube body, a piston head is fixedly connected to one end of the piston rod, and the piston head is slidably connected to the inside of the sampling tube body, a plurality of first connecting blocks are provided on the piston rod, and a second connecting block is provided at one end of the piston rod, a push block is detachably connected to one end of the piston rod, and a push plate is fixedly connected to one end of the push block.

[0005] Furthermore, the sampling tube body and the bottom plate are configured as an integral structure, a through slot is provided at the center of the bottom plate, and the push block is engaged and connected with the through slot.

[0006] Furthermore, a limiting groove is provided at one end of the push block, and a thread matching the first connecting block and the second connecting block is provided on the inner wall of the limiting groove.

[0007] Furthermore, a plurality of connecting rods are provided between a plurality of the first connecting blocks, and two adjacent first connecting blocks are detachably connected via the second connecting block.

[0008] Furthermore, a connection groove is formed at one end of the first connection block, a connection block is fixedly connected to one end of the connection rod, and the connection rod is engaged and connected with the connection groove.

[0009] Furthermore, a connecting belt is provided at one end of the sealing block, one end of the connecting belt is fixedly connected to one side of the sealing block, and one end of the sealing block matches the liquid inlet of the sampling tube body.

[0010] Furthermore, the sampling tube body, the sealing block and the bottom plate are all configured as transparent structures.

[0011] The beneficial effect of the utility model is that when transporting samples, the utility model will not squeeze the piston rod due to external force, resulting in the problem of the sample inside the sampling tube being squeezed out. Through the deformed piston rod, the device can be disassembled and assembled during sampling and transportation. After the sample inside the sampling tube is transferred, the device can be reused, so that the utility model can be directly stored after sampling, and the protection effect is better during transportation, and the sample will not leak out.
