Abstract

This utility model is a kind of defecator with novel plastic syringe, including seam (6), the syringe filters (7) of piston (1), lever fixing device (2), syringe body (3), lever push rod support means (4), lever push rod (5), syringe body (3) and syringe filters (7).Its objective is that providing a kind of has the defecator that novel plastic syringe is integrated with syringe filters.Novel plastic syringe has lever push rod, utilizes lever principle, can effectively amplify the propulsive force of user, reduces the pressure to user hand, reduces the replacing number of times of filter paper.Novel injector is connected in a spiral manner with syringe filters, makes both to separate the most voluntarily, and the filtration pretreatment in Water purification experiment brings great convenience.

Description

A kind of defecator with novel plastic syringe
Technical field
This utility model is a kind of defecator with novel plastic syringe, is divided into novel plastic syringe and syringe needle Filter two parts, belong to water treatment experiment articles for use field.
Background technology
In water treatment experiment, ordinary syringe head removes syringe needle, installs syringe filters as an alternative, promotes injection Sewage in syringe by the filter paper in syringe filters, is the most conventional a kind of small-sized filtration pretreatment unit by device. However it is necessary that the water sample of pretreatment usually contains float or water sample concentration is excessive, easily block filter paper.Use ordinary syringe pushes away Enter extremely difficult, and cause syringe and syringe filters easily separated the most by reason of heavy pressure, give the carrying out of experiment Bring obstruction.Existing countermeasure is to change filter paper, and 10mL water sample is accomplished by changing two to three filter paper, not only wasted filter paper but also Not environmentally.
Summary of the invention
This utility model purpose is, for present on not enough, a kind of mistake with novel plastic syringe is proposed Filter device.Novel plastic syringe has lever push rod and is provided with the outlet of external spiral, utilizes lever principle, lever construction Push rod can amplify the propulsive force of user, in the case of filter paper slightly blocks, can make smooth advances injector push-rod.With Water inlet in the syringe filters filtered is provided with and the novel injector corresponding internal coiling of water inlet external spiral, makes both with spiral shell Rotation mode is combined closely, in use will not self falling.
For achieving the above object, the technical solution of the utility model is as follows:
The defecator with novel plastic syringe includes piston (1), lever fixing device (2), syringe body (3), lever push rod support means (4), lever push rod (5), the seam of syringe body (3) and syringe filters (7), Syringe filters (7).There is the syringe body (3) of the plastic injector of lever metal pushrod, volume and conventional syringe There is identical specification, it has scale corresponding with volume, for plastic material.At body top outer wall, lever push rod is installed Support means (4), for metal material, support means is enclosed around main body one, and certain linking thereon has two arc metal plates, There is screw truck dead lever formula push rod (5) sheet metal upper end.Lever push rod is divided into two parts, and a part is in syringe body (3) connecting piston (1) in, another part in syringe body (3) outward, is arranged on lever push rod support means (4), two parts Connect with screw.Lever fixing device (2) is arranged on syringe body (3) centre position, for flexible plastic material, plastics ring Enclose around syringe body (3), have 3/4ths circular (internal diameter is more bigger than push rod external diameter) flexible plastic draw-in grooves in upper certain, should Draw-in groove and lever push rod support the strong point of its device (4) on same vertical curve.In the syringe not used time, can be by lever It is interior in order to fixing that push rod (5) is placed in draw-in groove.The external spiral of the outlet of novel plastic syringe and the water inlet of syringe filters (7) Mouth connects in a spiral manner at both seam (6) places.
Accompanying drawing explanation
Fig. 1 is the front view of the defecator with novel plastic syringe.
Fig. 2 is the right view of the defecator with novel plastic syringe.
Fig. 3 is the front view during defecator use with novel plastic syringe.
Wherein (1) be piston, (2) be lever fixing device, (3) be syringe body, (4) be that lever push rod supports dress Put, (5) are that lever push rod, (6) are syringe body (3) and the seam of syringe filters (7), (7) are syringe filters.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly, it is fully described by.
This utility model is a kind of defecator with novel plastic syringe.During use, first by lever push rod (5) Take out from the plastics draw-in groove of lever fixing device (2), lift lever push rod (5) and piston (1) is pushed into syringe body (3) Bottom, then lever push rod (5) is pressed down and piston (1) is pulled to syringe body (3) top, water sample is sucked into syringe In main body (3).By the outlet of novel plastic syringe with equipped with filter paper syringe filters (7) water inlet in a spiral manner Being connected firmly, then lifted by lever push rod (5), water sample is pressed to be filtered by syringe filters.After use terminates, by pin Head filter (7) is backed out, and the lever of the lever push rod (5) of novel injector is fixed on the plastic clip of lever fixing device (2) In groove, it is easy to place.Whole operating process is simple and easy to do, by lever principle, the propulsive force of the saved 2-3 of user times, has Effect reduces the pressure to user hand, also greatly reduces the replacing of filter paper, economical environment-protective.
