Description

Special support of portable atmospheric sampling appearance

Technical Field

The utility model belongs to the technical field of the atmosphere appearance auxiliary assembly that samples, especially, relate to a special support of portable atmosphere appearance that samples.

Background

An atmospheric sampler is an instrument or device that collects atmospheric pollutants or contaminated air. The types of the gas sampler and the particle sampler are various, and the gas sampler and the particle sampler can be divided into a gas sampler and a particle sampler according to the collection object; can be divided into an environment sampler, an indoor sampler and a pollution source sampler according to the using places. In addition, there are special purpose atmospheric samplers, such as samplers that simultaneously collect gas and particulate matter. The gas sampler generally consists of three parts, namely a collector, a flow meter and a pumping power system.

The atmosphere sampler plays a good role in detecting harmful gases in air and environment. With the continuous progress of science and technology, the air sampler is also a new product which is continuously pushed out. In order to ensure the comprehensiveness and accuracy of sampling, sampling measurement needs to be carried out on the atmosphere in different areas. The general cooperation A-frame of sampling appearance uses, and present sampling appearance support has some problems in the use, for example, the topography of partial sampling area is complicated, can't use normal vehicle, needs the measuring staff health power to go to the sampling area, and present sampling appearance support can't stretch out and draw back or dismantle, even can stretch out and draw back, but the sampling appearance volume after stretching out and drawing back is still great, bears such support and has increased sampling personnel's burden, has caused a great deal of inconvenience.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides a but portable atmosphere sampling appearance special stand of complete change fast, the utility model discloses simple structure, the operation is simple and easy, portable, and the practicality is very strong.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a special support of portable atmosphere sampling appearance, includes instrument base, support piece and support foot, and the instrument base is used for placing atmosphere sampling appearance, and support piece is used for supporting the instrument base, support piece is fixed to be set up on support foot, its characterized in that: the supporting piece is of a telescopic structure and comprises an installation base, a central rod, a supporting rod, a fixed sleeve, a connecting rod and an end sleeve, wherein a central round hole is formed in the middle of the installation base, the central rod penetrates through the central round hole and is movably connected with the installation base, the supporting rod is uniformly distributed on the periphery of the installation base, one end of the supporting rod is hinged with the installation base, the fixed sleeve is positioned below the central rod, the connecting rod is movably connected with the inside of the fixed sleeve, and the other end of the connecting rod is movably connected with the supporting rod through the end sleeve; the support leg comprises a plurality of sections of metal rods.

The scheme is further improved: the instrument base is provided with a through hole, and a longitudinal groove is formed in the through hole. The groove and the limiting strip on the boss are matched to prevent the instrument base from rotating to influence sampling of the atmospheric sampling instrument.

The scheme is further improved: the periphery of mount pad is equipped with vertical spacing strip and is located the spacing platform of circumference below vertical spacing strip. This setting is used for spacing to instrument base to guarantee that it is unlikely to slide from top to bottom or rotate from side to side.

The scheme is further improved: the bottom end of the central rod is provided with a hook. The hook is arranged for hooking a heavy object, so that the stability of the support is further improved.

The scheme is further improved: the bracing piece is 3, be equipped with the stopper below the bracing piece, the stopper is located the telescopic below of tip. 3 the bracing pieces form a plane after being opened, thereby ensuring the stability of the bracket.

The scheme is further improved: the supporting piece is of a telescopic structure, and particularly, the supporting piece can enable the supporting rod to be in an opening or contracting state when the central rod moves up and down in the central circular hole. When the supporting piece is not in operation, after the manpower upwards pulls the center rod, the manpower pushes 3 supporting rods towards the center rod, and because the connecting rod is movably connected with the supporting rods and the center rod, when the manpower pushes the supporting rods, the connecting rod can synchronously move upwards along with the center rod until the supporting rods are in a contraction state, so that the size of the supporting piece is reduced. When support piece during operation, the manpower promotes well core rod downwards, and the connecting rod that leads to being connected with well core rod opens 3 spinal branch vaulting poles, and 3 spinal branch vaulting poles are located the mutual butt of the one end in the fixed cover, and support piece is the open mode to reach outrigger's effect.

The scheme is further improved: the upper end of the metal rod is a threaded rod, and the other end of the metal rod is an inner threaded rod. The bracket legs are formed by the threaded connection of a plurality of sections of metal rods, and the portable bracket is convenient to carry.

The scheme is further improved: the support still includes universal callus on the sole.

Compared with the prior art, the utility model discloses the beneficial effect who brings does: the instrument base, the supporting piece and the bracket feet of the utility model are assembled in situ, when a complex terrain is encountered, a sampler can place all sampling devices together, for example, the sampler can be carried on the body by a bag, the sampler can save much effort by carrying on the shoulder, and both hands are also liberated; in addition, the support piece is telescopic, so that the stability of the support can be effectively enhanced when the support is opened, the size is reduced after the support piece is contracted, and the support is convenient to store.
