Embodiment 1

[0023] Such as figure 1 with figure 2 The shown embodiment 1 is a quantitative water injection syringe, including a cylinder body 1, a tube head 2 arranged on the left side of the cylinder body, a push-fit device 3 connected to the right side of the cylinder body, and a mobile device detachably connected with the push-pull device. Plate 4, a first platform 5 and a second platform 6 arranged adjacent to the axis of the cylinder, a swing device 11 and four balance weights 12 arranged on the cylinder; several first platforms are provided on the first platform. A sawtooth 7, the lower end surface of the moving plate is provided with several second sawtooths 8 that are compatible with the first sawtooth, and the front side of the moving plate extends a limiting plate 9 toward the direction of the second platform; the second platform There is a limit device 10 and a scale line on it; each of the first sawtooth and the second sawtooth is a right-angle sawtooth; the first platform a...

Embodiment 2

[0029] Such as image 3 The shown embodiment 2 is a quantitative water injection injector, and also includes a force plate 13 located on the upper end surface of the moving plate; the force plate is detachably connected with the moving plate; when the hull shakes, the water in the bucket will also Shaking produces an impact force, the force plate and the total push plate are affected by the impact force at the same time, the moving plate is accelerated to slide to the right, and at the same time, the piston and the push rod are also accelerated to move to the right, thereby accelerating the water absorption speed and improving the water intake efficiency ; All the other structures and methods of use of embodiment 2 are the same as embodiment 1.

Abstract

The invention discloses a quantitative water adding injector, which comprises a barrel, a pipe head arranged on the left side face of the barrel, a push-pull device connected to the right side of thebarrel, a movable plate detachably connected with the push-pull device, a first platform and a second platform, wherein the first platform and the second platform are arranged in the axis direction ofthe barrel and are adjacent; a plurality of first sawteeth are arranged on the first platform; a plurality of second sawteeth matched with the first sawteeth are arranged on the lower end face of themovable plate; the front side face of the movable plate extends towards the second platform to form a limiting plate; a limiting device is arranged on the second platform; and the first platform andthe second platform are tangent to the barrel. The quantitative water adding injector has the beneficial effects that water shakes and impacts the push-pull device, so that the movable plate is drivento move, automatic water taking is achieved, and the working efficiency is improved; and quantitative water taking is achieved through the limiting plate and the limiting device. The quantitative water adding injector is simple in structure and simple and convenient to operate, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of water injection device design, in particular to a quantitative water-filling injector capable of automatic water intake, simple and convenient in operation, and improved in work efficiency. Background technique [0002] Before testing the water quality, water samples must be collected. The current collection method of the staff is to collect seawater on the ship with a water collector and pour it into a bucket. When there is enough water in the bucket, then use a ladle to pour water into the sampling bottle ( Generally within 1L), when the wind and waves are strong and the hull shakes violently, this operation is very difficult, and the water in the scoop is easily spilled. When pouring into the sampling bottle, due to the shaking and the small mouth of the sampling bottle, the water will be large Part of it is outside, which is a very big challenge to the work efficiency of the staff. And holding the bo...
