Abstract
A rapid air-tightness test clamp of a needle-integrated injector comprises a pedestal, a lower press ring, an elastic O-shaped ring, an upper press ring and a fastening cover. The lower press ring, the elastic O-shaped ring and the upper press ring are sequentially stacked in a groove on the pedestal, and the fastening cover is connected with the screw thread in the groove of the pedestal througha fastening screw. The invention can seal the sheath of an injector to be tested by screwing the fastening screw to press the elastic O-shaped ring to deform, thus facilitating the air-tightness testof the needle-integrated injector. The invention has the advantages of convenient, rapid and safe usage, simple structure, easy manufacture, low cost and convenient generalization.
Description
Technical field
The present invention relates to a kind of machine equipment, particularly a kind of in the quick-speed jigs and the using method thereof of pin device integral injector being carried out be used for pressing from both sides the needle holder integral injector when impermeability detects.
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.
Summary of the invention
Purpose of the present invention, be to provide a kind of easily and fast, the pin device integral injector air tightness test rapid jigs and the using method thereof of safety.
Technical scheme of the present invention is: a kind of pin device integral injector air tightness test rapid jigs comprises:
A base comprises a handle and the cylindrical pedestal that fuses with the seat handle, is provided with a groove in the pedestal vertically, and bottom land is provided with the threaded hole that axially runs through a handle, and cell wall is provided with internal thread;
Lower clamping ring is arranged on the bottom land in the base groove;
Elastic O-ring is arranged on the lower clamping ring top in the base groove;
Last trim ring is arranged on the elastic O-ring top in the base groove;
Tightening cover comprises the tie down screw that covers handle and fuse with the lid handle, is provided with the through hole of axial perforation tightening cover in the tie down screw, and tightening cover is threaded with the groove of base by its tie down screw, and can be by screwing the distortion of tie down screw compressing elastic O-ring.
The natural external diameter of described elastic O-ring is less than the internal diameter of base groove.
The aperture of the internal diameter of the described internal diameter of going up trim ring, lower clamping ring, the natural internal diameter of elastic O-ring and the through hole in the tightening cover is all greater than the diameter of the overcoat of detected pin device integral injector.
Through hole in the described tightening cover forms a bellmouth entrance that outwards enlarges on the lid handle.
The using method of above-mentioned anchor clamps is, earlier external tracheae is connected on the threaded hole of base seat handle, then one hold base the seat handle, another holds the lid handle of tightening cover, allow the interior last trim ring of tightening cover and base be the state that contacts but do not exert pressure, then the through hole of measured syringe in tightening cover inserted and the outer of its front end is placed in the elastic O-ring, screw tightening cover then, elastic O-ring is out of shape under pressure, internal diameter diminishes, the overcoat of syringe is sealed up, can carry out the air tightness test of pin device integral injector.
The present invention is used for pin device integral injector is carried out impermeability clamping syringe when detecting, and have easy to use, quick, safe characteristics and advantage, and clamp structure is simple, and easy to manufacture, cost is low, and is easy to utilize.
Description of drawings
Fig. 1 is the structural representation of pin device integral injector air tightness test rapid jigs of the present invention.
Embodiment
Referring to Fig. 1, pin device integral injector air tightness test rapid jigs of the present invention comprises base 1, lower clamping ring 2, elastic O-ring 3, goes up trim ring 4 and tightening cover 5.
Elastic O-ring 3 is arranged on the lower clamping ring top in the base groove; The natural external diameter of elastic O-ring 3 is less than the internal diameter of base groove, and natural internal diameter is greater than the diameter of the overcoat of detected pin device integral injector 7.
The using method of pin device integral injector air tightness test rapid jigs of the present invention can be described as follows in conjunction with Fig. 1:
Earlier external tracheae 6 is connected on the threaded hole 14 of base seat handle, then one hold base the seat handle 11, another holds the lid handle 51 of tightening cover, allow the last trim ring 4 in tightening cover 5 and the base 1 be the state that contacts but do not exert pressure, then the through hole 53 of measured syringe 7 in tightening cover inserted and the outer of its front end is placed in the elastic O-ring 3, screw tightening cover 5 then, elastic O-ring 3 is out of shape under pressure, internal diameter diminishes, the overcoat of syringe 7 is sealed up, can carry out the air tightness test of pin device integral injector.After testing, unscrew tightening cover 5, pin device integral injector 7 can be taken out easily.
