Abstract
A rapid clamp for needle tubes with a diameter less than 0.4mm comprises a coupling rod, a locking body and two locking blocks; the coupling rod is formed by a rod pedestal and a cylindrical rod body connected with the rod pedestal, and the rod body is provided with an outer screw thread; the locking body is of a cylindrical structure, one end of the locking body is provided with an inner screw thread which is connected with the screw thread of the rod body of the coupling rod, the other end, the front end of which is provided with a conical groove, is provided with an outer screw thread, and a small hole is extended on the bottom of the groove; the two locking blocks are shaped like two semicircular cones, which are combined together to form a circular cone that is arranged in the conical groove of the front end of the locking body, and the diameter of the big end of the combined circular cone is larger than the diameter of the orifice of the conical groove of the front end of the locking body. The rapid clamp resolves the problem that the needle tubes with a diameter less than 0.4mm are hard to be clamped, and has the advantages of convenient, rapid and safe use, simple structure, easy fabrication and low cost.
Description
Technical field
The utility model relates to a kind of machine equipment, and is particularly a kind of with the pulling capacity of the omnipotent tensiometer of ZWICK test Conjuncted syringe needle tubing the time, is used for clamping the quick-speed jigs of the following needle tubing of 0.4mm of measured syringe.
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 200620162327.X at application number, the applying date is on Dec 28th, 2006, the utility model name is called in the patented claim of " quick-speed jigs of the following needle tubing of 0.4mm ", a kind of 0.4mm is provided the quick-speed jigs of following needle tubing, 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 the quick-speed jigs of the following needle tubing of this 0.4mm, 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, the following needle tubing quick-speed jigs of 0.4mm that cost is lower.
Technical scheme that the utility model provides is: the following needle tubing quick-speed jigs of a kind of 0.4mm is characterized in that comprising:
A pitman shaft is made up of a pole socket and the cylindrical body of rod that is connected on the pole socket, and the body of rod is provided with external thread
A locking body is cylinder bodily form structural member, and the one end is provided with internal thread and is threaded with the body of rod of pitman shaft, and the other end is provided with external thread and is provided with a cone tank at its front end, and bottom land is postponed an aperture;
Two latch segments are two semicircle cones, and the two halves cone is combined full circle cone of formation and is arranged in the cone tank of locking body front end, and the outside diameter of the cone of combining is greater than the notch diameter of the cone tank of locking body front end.
At the following needle tubing quick-speed jigs of above-mentioned 0.4mm, the big end inboard of two latch segments respectively is provided with a scarf, makes and forms a taper groove on the large end face of the cone of combining.
The utility model is used for being used for clamping the following needle tubing of 0.4mm of measured syringe when testing the pulling capacity of Conjuncted syringe needle tubing with the omnipotent tensiometer of ZWICK, has solved the difficult problem of the bad clamping of the following needle tubing of 0.4mm.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 following needle tubing quick-speed jigs of the utility model 0.4mm.
Embodiment
Referring to Fig. 1, the following needle tubing quick-speed jigs of the utility model 0.4mm comprises pitman shaft 1, locking body 2, two latch segments 3.
Pitman shaft 1 is made up of the pole socket 11 and the cylindrical body of rod 12 that is connected on the pole socket, and the body of rod is provided with and is used for the external thread that is connected with locking body.
Two latch segments 3 are two semicircle cones, the two halves cone is combined full circle cone of formation and is arranged in the cone tank 21 of locking body 2 front ends, the outside diameter of the cone of combining is greater than the notch diameter of the cone tank of locking body front end, when making two latch segments 3 be placed in the cone tank 21, there is one section to expose outside groove, is convenient to its application of force.The big end inboard of two latch segments 3 respectively is provided with a scarf (not shown come out), makes on the large end face of the cone of combining and forms a taper groove, is convenient to tested needle tubing and inserts.
The following needle tubing quick-speed jigs of the utility model 0.4mm is used for being used for clamping the measured syringe needle tubing when testing the pulling capacity of Conjuncted syringe needle tubing with the omnipotent tensiometer of ZWICK.Its concrete using method can be described as follows in conjunction with Fig. 1:
One holds the pole socket 11 of pitman shaft 1, clamping locking body 2 is operated on the other hand, make two latch segments 3 be relaxed state, then the needle tubing with measured syringe 5 inserts between two latch segments 3 from the taper groove on two latch segments 3, and make two latch segments be locking state, tested needle tubing is clamped, can test.
Claims (2)
