Abstract
The utility model discloses a quick clamping fixture used to clamp a needle tube with a diameter below 0.4mm. The clamping fixture comprises a connecting lever, a locking body, two locking blocks and a locking cap. The locking body is connected with the connecting lever, the connecting blocks are arranged into a tampered groove in the locking body, and the locking cap is capable of clamping the locking blocks in combination with the locking body. The utility model resolves the difficulty in clamping a needle tube with a diameter below 0.4mm, has the advantages of convenient use, quickness and safety, and is simple in structure, easy in manufacturing, low in cost, and convenient in promotion.
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 utility model content
The purpose of this utility model, be to provide a kind of easily and fast, the following needle tubing quick-speed jigs of 0.4mm of safety.
The technical solution of the utility model 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;
A 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 outer end of described locking cap is tapered, and described pin hole is arranged on the vertex of a cone.
The outer wall of described locking cap is provided with rough surface.
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, 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 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 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 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.
