Abstract
The utility model discloses a needle integrated injector leakage test quick cramping apparatus, which comprises a base, an elastic O-shaped ring and a locking cover. The integrated injector leakage test quick cramping apparatus is characterized in that the base comprises a base handle and a cylindrical base body connected with the base handle to a whole; a groove is arranged in the base body in the axial direction; the groove bottom is provided with a threaded hole passing through the base handle in the axial direction; a female screw thread is arranged on the groove wall; the elastic O-shaped ring is arranged at the bottom of the base groove; the locking cover comprises a cover handle and a locking screw bolt connected with the cover handle into a whole; a through hole passing through the locking cover is arranged in the locking screw bolt in the axial direction; the locking cover is connected with the groove of the base through the locking screw bolt and can press the elastic O-shaped ring to deform through tightly screwing the locking screw bolt in the screw thread way. The needle integrated injector leakage test quick cramping apparatus used for gripping the injector when in the leakage test on the needle integrated injector has the advantages of convenient, fast and safe use, simple structure, easy production, low cost, and convenient popularization and application.
Description
Technical field
The utility model relates to a kind of machine equipment, particularly a kind of quick-speed jigs that is used for pressing from both sides the needle holder integral injector when pin device integral injector being carried out the impermeability detection.
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 200720066112.2 at application number, the applying date is on January 4th, 2007, the utility model name is called in the patented claim of " pin device integral injector air tightness test rapid jigs ", a kind of pin device integral injector air tightness test rapid jigs 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 pin device integral injector air tightness test rapid jigs, 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, pin device integral injector air tightness test rapid jigs that cost is lower.
The technical solution of the utility model is: a kind of pin device integral injector air tightness test rapid jigs, comprise base, elastic O-ring and tightening cover, it is characterized in that: base, comprise a handle and the cylindrical pedestal that fuses with the seat handle, be provided with a groove in the pedestal vertically, bottom land is provided with the threaded hole that axially runs through a handle, and cell wall is provided with internal thread; Elastic O-ring is arranged on the bottom of 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.
In above-mentioned pin device integral injector air tightness test rapid jigs, the natural external diameter of elastic O-ring is less than the internal diameter of base groove.
In above-mentioned pin device integral injector air tightness test rapid jigs, the through hole in the tightening cover forms a bellmouth entrance that outwards enlarges on the lid handle.
The utility model 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 the pin device integral injector air tightness test rapid jigs after the utility model promptly improves.
Embodiment
Referring to Fig. 1, the utility model pin device integral injector air tightness test rapid jigs comprises base 1, elastic O-ring 3 and tightening cover 5.
Elastic O-ring 3 is arranged on the bottom of 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 the utility model pin device integral injector air tightness test rapid jigs 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, 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, and 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.
