Description

Auxiliary box for pushing and injecting needle tube of filter

Technical Field

The utility model belongs to the technical field of laboratory auxiliary assembly, concretely relates to supplementary box is injected to filter needle tubing.

Background

Every time a laboratory samples, the laboratory needs to use manpower to push out a water sample from a needle tube with a filter so as to obtain an analyzable sample. However, in order to ensure the experimental precision, the filter screen of the filter is very fine, the needle tube is very labored to wash water during sampling, a large force is often needed to work, and a small tube cannot be drilled for a long time; meanwhile, because the volume of each needle tube is very small and the water samples are many, a large amount of repeated work is required to be carried out in each water sample collection, and therefore a large amount of manpower and time are occupied.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art not enough, provide a supplementary box is injected to filter needle tubing that uses manpower sparingly, time.

In order to achieve the above design purpose, the utility model adopts the following technical scheme: a filter needle tube injection auxiliary box comprises a lower box body, an upper box body, a push plate and a jack, wherein connecting lugs are arranged at the edge of one side of the lower box body and the upper box body, the lower box body and the upper box body are mutually hinged through the connecting lug at the edge of one side, a water receiving groove is arranged at the top in the lower box body, a plurality of groups of symmetrical semicircular needle tube accommodating grooves are respectively arranged at the middle parts in the lower box body and the upper box body, symmetrical push plate moving compartments are respectively arranged at the inner bottoms of the lower box body and the upper box body, guide sliding grooves are respectively arranged on the side walls at the two sides of the bottom in the lower box body, push plate accommodating openings are formed at the connecting parts of the side walls at the two sides of the bottom in the lower box body and the inner wall of the bottom in the lower box body, the push plate is placed at the bottom in the lower box body, sliding, the bottom end center department is equipped with the jack in the lower box body, the jack top surface is equipped with the roof, go up the box body top surface and offer the regulation mouth that is used for adjusting the bottom jack adjusts the pole in the lower box body.

And rubber soft pads are arranged at the stress positions of the top and the bottom outer wall in the semicircular needle tube placing groove.

The guide sliding groove and the sliding block are of a matched trapezoidal structure.

The utility model discloses beneficial effect: the water receiving tank that the internal top of lower box set up can all concentrate the water receiving tank with filter needle exhaust waste water, and the effectual waste water turbulence problem of having avoided drainage in-process to lead to the pollution in the laboratory, the rubber cushion that all sets up is located with the atress of bottom outer wall in the inslot top is placed to semi-circular needle tubing, and the effectual needle tubing that prevents produces the phenomenon emergence that bursts because of the too violent or uneven atress of atress. The utility model discloses simple structure, the cost is with low costs, can carry out a plurality of filter needle tubes drainage work simultaneously according to the experiment demand, and is fast, and one-man operation does not have the physical requirement to the user simultaneously, can promote drainage efficiency greatly, saves a large amount of manpowers and time.
