Embodiment
The utility model discloses a kind of measurement apparatus of replaceable measurement syringe needle, including measurement main body and measuring pen.Wherein,
Measuring pen includes measurement syringe needle, Handheld Division and the measurement line being sequentially connected, and measures syringe needle and Handheld Division and is flexibly connected, Handheld Division with
Measurement line is fixedly connected, and measuring pen is connected to measurement main body by measuring line.
Wherein, it is metalwork to measure syringe needle, including the measurement end contacted with testee and the connection end of insertion Handheld Division.
Measurement end can make the shapes such as needle-like, taper, flat pattern respectively according to demand, and syringe needle size can be true according to practice
It is fixed.One and half logical interconnections are provided with inside connection end, a telescopic spring is provided with interconnection and is consolidated with spring
Surely the metal ball (ball-type metal structure) connected, a part for metal ball protrude from survey positioned at measurement needle wall, another part
Outside metering pin head.
The inside of Handheld Division includes a hollow cavity adaptable with measurement syringe needle and test pencil wire shaped size, for cloth
Put the measurement syringe needle being connected with Handheld Division and measurement line.One piece of metallic gasket is provided with hollow cavity, metallic gasket one end is with stretching
The one end for entering the measurement line inside Handheld Division is fixedly connected, and the other end can be connected by a groove with the metal of the measurement syringe needle of insertion
Connect end to be in close contact, the part that the shapes and sizes of groove protrude with metal ball is just adapted.So as to realize measurement syringe needle and
The plug type connection of Handheld Division.
When installation measures syringe needle, measurement needle wall is pressed into by the compressed metal ball of spring, measures the company of syringe needle
Connect end smoothly to insert in the inner chamber of Handheld Division, metal ball is stuck in groove just in groove by the stretching, extension of spring, plays certainly
The effect of lock measurement syringe needle, prevents Automatic-falling during use.When changing measurement syringe needle, due to the cooperation of metal ball and spring
Effect, somewhat measurement syringe needle can firmly be pulled.
When in use, measurement syringe needle can have multiple simultaneously, so can be according to measured object shape or measuring point shape
It is different change measurement syringe needles, improve measurement levels of precision and reliability.It is smaller in view of measurement syringe needle, it is easily lost, this reality
A kind of measurement needle tip storage structure is have also been devised at the universal meter body back side with new, will not for depositing these measurement syringe needles
In loss.Measurement needle tip storage structure is arranged in the main body of measurement apparatus.
With reference to Fig. 1 to Fig. 3, measurement apparatus further illustrates the utility model by taking universal meter as an example in embodiment.
As shown in figure 1, universal meter includes universal meter body 1 and positive and negative two measuring pens 2, measuring pen 2 includes measurement syringe needle
3rd, Handheld Division 4 and measurement line 5.
It is made of metal as shown in Fig. 2 measurement syringe needle 3 is overall, there is connection end 31 and measurement end 32.In connection end 31
