Abstract

The utility model relates to a ration clamp of a glass injector. The ration clamp comprises an outer needle cylinder, an air pushing rod arranged in the outer needle cylinder and scale marks engraved on the surface of the outer needle cylinder, a fixed disc sleeved outside the outer needle cylinder, a fixed bolt which is arranged on the side face of the fixed disc in a penetrating manner and the head of which is contact with the wall of the outer needle cylinder, upper and lower pointer cross rods which are fixedly arranged on the left side face of the outer needle cylinder and parallel with the wall of the outer needle cylinder, two ration pointers which are arranged on the inner sides of left end parts of the upper and lower pointer cross rods and perpendicularly point to the wall of the outer needle cylinder, as well as an L-shaped ration clamping support fixedly arranged on the right side face of the fixed disc. The ration clamp provided by the utility model is an additional device of the original injector, the two-way ration pointers can meter and monitor the capacity at any time, the ration clamp can be fixed in two directions, the size is regulated, the ration taking/feeding sample of injectors of different specifications is realized, the taking/feeding sample is rapidly and accurately measured, and waste is avoided.

Description

Quantitative clip for glass syringe

technical field

The utility model belongs to the technical field of transformer oil gas chromatography test in electric power systems, in particular to a quantitative clip for a glass syringe.

Background technique

At present, most of the existing devices that can realize the quantitative function of glass syringes are the syringe itself. Although the syringe itself has a quantitative mark, the quantitative injection or sampling depends on the cooperation of human eyes and hands. It is difficult to achieve accurate sampling and injection quantitative. In addition, the difference between each person is also relatively large, which brings great difficulties to accurate metering, sampling and injection, resulting in a waste of original resources.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art and provide a quantitative clamp for glass syringes.

The utility model solves its technical problem and realizes by taking the following technical solutions:

A quantitative clip for a glass syringe, comprising an outer syringe, an air push rod placed inside the outer syringe, and a scale line engraved on the surface of the outer syringe. Mounted on the side of the fixed plate, the fixed bolt whose head is in soft contact with the outer needle cylinder wall, the upper and lower pointer crossbars fixed on the left side of the fixed disk and parallel to the outer needle cylinder wall, and the upper and lower pointer crossbars On the inner side of the left end, there are two quantification pointers vertically pointing to the outer syringe wall, and an L-shaped quantification card holder fixed on the right side of the fixed plate.

Moreover, when the air push rod is pushed to the left bottom of the outer syringe, the distance from the outside of the right end of the push rod to the inside of the plane of the right end of the L-shaped quantitative card support is equal to the scale of the outer syringe indicated by the quantitative pointer. The readings correspond.

Advantage and positive effect of the present utility model are:

The utility model device is an additional device of the original syringe, with a two-way quantitative pointer, which can measure and monitor the capacity, and can monitor at any time; it has a two-way fixed valve, which can adjust the size, and realizes the quantitative taking/feeding of syringes of different specifications. It can not only quickly and accurately measure and take/inject samples, but also avoid waste.

Description of drawings

Fig. 1 is a structural view of the utility model.

Detailed ways

The following embodiments of the utility model are described in further detail in conjunction with the accompanying drawings. The following embodiments are only descriptive, not limiting.

The protection scope of the present utility model cannot be limited by this.

A quantitative clip for a glass syringe, as shown in Figure 1, includes an outer syringe 1, a push rod 6 placed in the outer syringe and a scale line 8 engraved on the surface of the outer syringe. The innovation of the present invention is that further Including the fixed plate 4 set on the outer side of the outer needle cylinder, the fixed bolt installed on the side of the fixed plate, and the head is in soft contact with the outer needle cylinder wall 5, the upper and lower two fixed on the left side of the fixed plate and parallel to the outer needle cylinder wall Pointer cross bar 3, be installed on two pointer cross bar left end inboards up and down, vertically point to two quantitative pointers 2 of outer syringe wall, be installed in the L-shaped quantitative card support 7 on the right side of fixed plate.

In the specific implementation of the present utility model, when the pusher rod is pushed to the left bottom of the outer syringe, the distance from the outside of the right side end of the pusher rod to the inside of the plane of the right end of the L-shaped quantitative card support is equal to the quantitative Corresponds to the reading on the outer syringe scale indicated by the pointer.

application principle

When the utility model is in use, first set the fixed plate on the outer side of the outer needle cylinder, then point the quantitative pointer to the measurement to be extracted or pushed out in the experiment, tighten the fixing bolts to fix the fixed plate on the outer side of the outer needle cylinder, and then use the quantitative card holder operate within the limits.
