Abstract

A rapid clamp for the core rod of a tested injector consists of a base core, two clamping blocks and a locking ring; wherein, the two clamping blocks clamp the rod body of the base core, the external body of which is shaped like a conical cylinder; the rear ends of the two clamping blocks can be moved towards the core rod of the base core; the locking ring is nested on the two clamping blocks and is a rigid metal ring; the inner diameter of the locking ring matches the outer diameter of the front ends of the two clamping blocks which form the cylindrical body; and the outer side of the locking ring is shaped like a circular arc. When being used to test the core rod of an injector, the rapid clamp clamps the core rod of the injector, and the rapid clamp has the advantages of convenient, quick and safe use, simple structure, easy fabrication and low cost.

Description

A kind of measured syringe core rod rapid jig

Technical field

The utility model relates to a kind of machine equipment, particularly a kind of quick-speed jigs that is used for the clamping measured syringe core rod when syringe core rod is detected.

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 fixture of safety, to satisfy detection needs to the small-sized medical instrument parts.

The applicant is 200720066111.8 at application number, the applying date is on January 4th, 2007, the utility model name is called in the patented claim of " measured syringe core rod rapid jig ", a kind of measured syringe core rod rapid jig is provided, a kind of convenience though these anchor clamps be can yet be regarded as, fast, the small fixture of safety, but in use still remain in ease of use, further raising in rapidity and the security, especially relative cost can also further reduce, therefore the applicant endeavours to improve this measured syringe core rod rapid jig, in the hope of reaching optimized effect.

The utility model content

The purpose of this utility model be to provide a kind of in ease of use, rapidity and security better effects if, measured syringe core rod rapid jig that cost is lower.

The technical solution of the utility model is: a kind of measured syringe core rod rapid jig comprises a basic core, two clamps and clamp ring, it is characterized in that, two clamp clampings are on the body of rod of basic core, and the outside is whole tapered cylindric, and the rear end of two clamps can be moved to basic core core bar; Clamp ring is sleeved on two clamps, is the rigid metal circle, and its internal diameter is suitable with the external diameter of the two clamp front ends that constitute cylinder bodily form integral body, and the outside is circular arc.

In above-mentioned measured syringe core rod rapid jig, described clamping becomes the front end of whole two clamps to be provided with a cap that diameter is bigger, and this cap can block that clamp ring is unlikely outwards to skid off.

Clamping measured syringe core rod when the utility model is used to detect syringe core rod has easy to use, quick, safe advantage, and simple in structure, easy to manufacture, and cost is low, and is easy to utilize.

Description of drawings

Fig. 1 is the one-piece construction synoptic diagram of the utility model measured syringe core rod rapid jig.

Embodiment

Referring to Fig. 1, the utility model measured syringe core rod rapid jig comprises basic core 1, two clamps 2, clamp ring 3.

Base core 1 is made up of the pedestal 11 and the cylindrical body of rod 12 that is connected on the pedestal.

2 clampings of two clamps are on the body of rod 12 of basic core, and the outside is whole tapered cylindric, and the rear end of two clamps 2 can be moved to basic core bar body 12;

Clamping becomes the front end of whole two clamps 2 to be provided with a cap 25 that diameter is bigger, and this cap 25 can block that clamp ring 3 is unlikely outwards to skid off.

Clamp ring 3 is sleeved on two clamps 2, is the rigid metal circle, and its internal diameter is suitable with the external diameter of the two clamp front ends that constitute cylinder bodily form integral body, and the outside is circular arc.

Claims

1. a measured syringe core rod rapid jig comprises a basic core, and two clamps and clamp ring is characterized in that,
