Constant current sampler with angle convenient to adjust

Abstract

The invention discloses a constant current sampler with the angle convenient to adjust. The constant current sampler with the angle convenient to adjust comprises a sampler body, a holding frame and three telescopic rods. A buffering plate is arranged at the bottom end of the sampler body. The bottom end of the holding frame is provided with a first threaded cylinder through a bearing. The telescopic rods are all provided with fixing bolts through threads. Lower rods of the telescopic rods are all hinged to second threaded cylinders. According to the constant current sampler with the angle convenient to adjust, by arranging fastening bolts and clamping plates on the two sides of the holding frame, multiple kinds of sampler bodies of different volumes can be fixed, the structure is simple,and use is convenient and rapid. By arranging the buffering plate and buffering springs in the holding frame, a buffering function can be achieved when the sampler body is placed in the holding frame;and the sampler body is expensive, shake generated when the sampler body is placed can cause parts in the sampler body to be loose, the sampler body is damaged, the buffering plate and the bufferingsprings can conduct buffering to protect the sampler body, and therefore economic loss is reduced.

Description

technical field [0001] The invention relates to the technical field of constant current samplers, in particular to a constant current sampler which is convenient for angle adjustment. Background technique [0002] With the rapid development of urbanization and industrialization in my country in recent years, the problem of urban air pollution has become more and more serious, which has brought many health and safety hazards and threats to urban residents. With the continuous development of many advanced analysis methods, the analysis and testing level of environmental samples has been greatly improved. The constant current sampler in the prior art is composed of a support frame and a constant current sampler body, but because the support frame has a certain length, it is inconvenient to place it together with the constant current sampler body for carrying, so the constant current sampling Carrying and transporting the device brings troubles. The support frames in the exist...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a constant current sampler that is easy to adjust the angle to solve the problem that the support frames in the prior art proposed in the above background technology are all fixed lengths, so they cannot be well adapted to the personal requirements of users. It is very troublesome to adjust the angle of the support frame. It needs to be adjusted one by one, which is not convenient for work, and the height cannot be adjusted stably.
