Abstract
A needle tube rapid clamping apparatus comprises a coupling rod, a locking element, two locking blocks and a locking cap. The locking element is connected on the coupling rod, the two locking blocks are positioned inside a conical groove on the locking element, and the locking cap is connected with the locking element for clamping the two locking blocks. The application method of the invention comprises the following steps of: releasing the locking cap to relax the two locking blocks, inserting the detected needle tube from a needle hole on the locking cap and inserting into the space between the two locking blocks from the conical groove above the two locking blocks, and winding the locking cap to lock the two locking blocks, so as to clamp the detected needle tube. The invention solves the clamping difficult of the needle tube with diameter less than 0.4mm, and has the advantages of convenient, rapid and safe application, simple structure, easy production, low cost, and easiness for popularization.
Description
Technical field
The present invention relates to a kind of machine equipment, particularly a kind of the time with the pulling capacity of the omnipotent tensiometer of ZWICK test Conjuncted syringe needle tubing, be used for clamping the quick-speed jigs and the using method thereof 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.
Summary of the invention
Purpose of the present invention, be to provide a kind of easily and fast, the following needle tubing quick-speed jigs of 0.4mm and the using method thereof of safety.
Technical scheme of the present invention is: the following needle tubing quick-speed jigs of a kind of 0.4mm comprises:
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;
Locking cap is threaded and can exerts pressure to two latch segments with the front end of locking body, is provided with a pin hole adaptive with tested needle tubing on the axis of locking cap.
The big end inboard of described 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 top of described locking cap is tapered, and described pin hole is arranged on the awl point of the vertex of a cone.
The using method of above-mentioned anchor clamps is, unclamps locking cap earlier, makes two latch segments be relaxed state, tested needle tubing is inserted between two latch segments from pin hole insertion and the taper groove from two latch segments on the locking cap, screw locking cap then, make two latch segments be locking state, tested needle tubing is clamped.
The present invention 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, easy to manufacture, cost is low, and is easy to utilize.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the following needle tubing quick-speed jigs of 0.4mm of the present invention.
Embodiment
Referring to Fig. 1, the following needle tubing quick-speed jigs of 0.4mm of the present invention comprises pitman shaft 1, locking body 2, two latch segments 3 and locking cap 4.
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 locking cap 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.
Locking cap 4 is threaded with the front end of locking body 2, is provided with a pin hole 41 adaptive with tested needle tubing on the axis of locking cap 4.When actual fabrication, be that the outer end with locking cap 4 is made into taper, pin hole is arranged on the vertex of a cone, and the outer wall of locking cap is made into rough surface, be convenient to like this grip and operate with hand.
The using method of the following needle tubing quick-speed jigs of 0.4mm of the present invention can be described as follows in conjunction with Fig. 1:
One holds the pole socket 11 of pitman shaft 1, clamping locking cap 4 is operated on the other hand, unclamp locking cap 4 earlier, make two latch segments 3 be relaxed state, then the needle tubing with measured syringe 5 inserts between two latch segments 3 from pin hole 41 insertions and the taper groove from two latch segments 3 on the locking cap, screws locking cap 4 then, makes two latch segments be locking state, tested needle tubing is clamped, can test.
