Abstract

The invention provides a device for testing needle point perpendicularity of a combined syringe and an application method thereof. The device comprises a body, a point gauge block, a spring, and a pointer. When using the device, the needle point of the combined syringe to be tested is inserted to a conical groove of the point gauge block and rotated, the non-perpendicular needle point shall drive the point gauge block to rotate when being rotated, the point gauge block drives the pointer to rotate via a rotor shaft, and then the perpendicularity of the needle point of the combined syringe can be tested from the inclination of the pointer. The invention has the advantages of convenient, rapid and safe service, simple structure, easy manufacturing, low cost, and easy generalization.

Technical field
The present invention relates to a kind of machine equipment, particularly a kind of Conjuncted syringe needle point detector perpendicularity detector and using method thereof.
Background technology
At medical device industry, need the performance or the quality of the medicine equipment produced be detected.For some less medicine equipment parts, be not easy to detect, and can not hold clamp in fact with big clamping instrument with big detecting instrument.Therefore, artificial situation about detecting with hand clamping detected element appears in regular meeting, and labour intensity is bigger on the one hand for this, can influence the accuracy of detection on the other hand, even also may cause industrial accident.Therefore be necessary to design and manufacture a kind of easily and fast, the small detector of safety, to satisfy detection needs to the small-sized medical instrument parts.
Summary of the invention
Purpose of the present invention, be to provide a kind of easily and fast, the Conjuncted syringe needle point detector perpendicularity detector and the using method thereof of safety.
Technical scheme of the present invention is: a kind of Conjuncted syringe needle point detector perpendicularity detector comprises:
A matrix is cube shaped member, comprises upper and lower surface, left and right sides end face and front and back sides, and its middle part is provided with a square hole that runs through front and back sides, and is provided with a circular hole that runs through left and right sides end face, and its upper surface is provided with a rectangular channel;
A chaining pin piece is rectangular block, is arranged in the middle square hole of matrix and is fixed in the rotating shaft of a up and down connection, and the right-hand member of chaining pin piece is provided with a groove that is used to insert the up/down perforation of measured syringe needle point;
A spring, the one end is connected the left end of chaining pin piece, and the other end is connected in the circular hole of matrix left end;
One root pointer is arranged in the rectangular channel of body upper surface, and by a needle handle and fixedly same rotating shaft of chaining pin piece be fixedly linked.
The diameter of the described circular hole that is arranged on the matrix right side and the overcoat of measured syringe are suitable.
The described groove that is arranged on the up/down perforation of chaining pin piece right-hand member is a cone tank wide outside and narrow inside.
The using method of above-mentioned detecting device is: tested Conjuncted syringe needle point is inserted in the cone tank of chaining pin piece and rotate needle point, the off plumb needle point will drive the chaining pin piece and rotate when rotating, the chaining pin piece drives pointer by rotating shaft and rotates, and predicts the verticality of syringe needle point from the measure of skewness of pointer.
Conjuncted syringe needle point detector perpendicularity detector of the present invention has easy to use, quick, safe characteristics and advantage, and simple in structure, and is easy to manufacture, and cost is low, easy to utilize.
