Description

Technical Field

[0001] The utility model relates to the technical field of chemical quality inspection, and specifically relates to a safe sampler which is convenient for storage and carrying. Background Technique

[0002] Chemical industry is the abbreviation of "chemical technology", "chemical industry", "chemical engineering", etc. All technologies that use chemical methods to change the composition, structure or synthesize new substances belong to chemical production technology, that is, chemical technology, and the products obtained are called chemical products or chemical industrial products. At first, these products were produced in handicraft workshops, and later evolved into factories, and gradually formed a specific production industry, namely the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products. The relationship between humans and the chemical industry is very close. Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials, and their chemical raw materials are further divided into different forms, such as liquid and solid. When modern chemical raw materials are used or mixed, a small amount needs to be extracted for quality inspection to ensure their normal use.

[0003] For example, the patent document with the application number 202222718751.X discloses a safe sampler. The utility model discloses a safe sampler, which includes a hollow sampling tube, and a sampling and cleaning structure is arranged on the hollow sampling tube; the sampling and cleaning structure includes: a finger rest, a frame body, a disc, a rotating shaft, a turntable, an electric push rod, a counterweight block, a cleaning brush, a plug and a protection component; the finger rest is installed on the hollow sampling tube. The utility model relates to the technical field of chemical product sampling. When sampling chemical products, the hollow sampling tube can be used to sample liquid chemical products and solid chemical products. After sampling, the plug is placed at the lower end of the hollow sampling tube, the cleaning liquid is injected into the hollow sampling tube, and the cleaning brush is used to clean the inner wall of the hollow sampling tube. After cleaning, the plug is opened to discharge the sewage, improving the safety of the hollow sampler and avoiding the pollution of the sample during the next sampling. When the hollow sampling tube is not in use, the protection component is used to protect the hollow sampling tube. However, for this safe sampler, when carrying it after sampling, if only simple protection is carried out, the sampling tube will become loose due to shaking and other reasons during carrying, and the sample inside the sampling tube is easily damaged.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a safe sampler which is convenient for storage and carrying is proposed. Content of the Utility Model

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As Figures 1 - 3 shown, a safety sampler convenient for storage and carrying includes a protective housing 1. A threaded groove 101 is provided on the upper end surface of the protective housing 1, and a protective cover 102 is spirally installed on the surface of the threaded groove 101, and a handle 103 is provided at the upper end of the protective cover 102. The advantage of this setting is that through the setting of the handle 103, it is convenient to carry the protective housing 1.

[0021] Furthermore, a telescopic rod 201 is provided on the inner wall of the protective housing 1, and a compression spring 202 is installed on the surface of the telescopic rod 201. The advantage of this setting is that through the setting of the telescopic rod 201, the compression spring 202 can be limited, and through the setting of the compression spring 202, the clamping plate 2 can be pushed up by compression.

[0022] Furthermore, a clamping plate 2 is provided at the front end of the telescopic rod 201, and balls 203 are provided on both sides of the surface of the clamping plate 2. The advantage of this setting is that through the setting of the clamping plate 2, after the sampling of the sampling tube 4 is completed and it is placed inside the protective housing 1, the compression spring 202 supports the clamping plate 2 to fix the sampling tube 4, ensuring the stability of the sampling tube 4 during the carrying process, facilitating better carrying of the sampling tube 4, and at the same time protecting the sampling tube 4. Through the setting of the balls 203, it is convenient to take out the sampling tube 4.

[0023] Furthermore, a sampling tube 4 is provided on the upper end of the placing seat 303, and a sealing cover 401 is provided on the upper end surface of the sampling tube 4. The advantage of this setting is that through the setting of the sampling tube 4, chemical raw materials can be sampled.

[0024] As Figure 4As shown in the figure, a fixed base 301 is provided at the bottom of the protective housing 1, a tension spring 302 is provided at the upper end of the fixed base 301, a placement seat 303 is provided at the upper end of the tension spring 302, and a placement groove is formed on the surface of the placement seat 303. The advantage of this setting is that through the setting of the tension spring 302, the sampling tube 4 on the placement seat 303 can be protected, and the vibration received by the sampling tube 4 can be reduced.

[0025] Furthermore, a pull plate 304 is provided on the surface of the placement seat 303, a sliding groove 3 is formed on the surface of the protective housing 1, and the sliding groove 3 is slidably connected to the pull plate 304. The advantage of this setting is that through the setting of the pull plate 304, the placement seat 303 can be driven to move along the sliding groove 3 to take out the sampling tube 4.

[0026] Working principle: When using this portable and safe sampler, first, after the sampling with the sampling tube 4 is completed and sealed with the sealing cap 401, it is slid into the interior of the protective housing 1. The compression spring 202 compresses against the clamping plate 2 to fix the sampling tube 4, and then the protective cover 102 is screwed onto the upper end of the protective housing 1. The handle 103 is lifted to carry and move. When it is necessary to take out the sampling tube 4, after the protective cover 102 is opened, the pull plate 304 is pulled upward to drive the placement seat 303 to slide the sampling tube 4 out of the protective housing 1 along the sliding groove 3. After the sampling tube 4 is taken out, the pull plate 304 is released, and the tension spring 302 drives the placement seat 303 to reset through reset. This is the working principle of this portable and safe sampler.
