Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, this utility model is further elaborated.
As shown in Figure 1, 2, 3, the telescopic pin of syringe needle disclosed in this utility model, including needle stand 1, slide block 2, needle body 3, spring 5 and shell fragment 6, needle stand 1 is provided with separate pilot hole 4 and fluid passage 7, an end face of needle stand 1 is run through in fluid passage 7 one end, fluid passage 7 other end connection pilot hole 4, pilot hole 4 extends transversely through another end face of needle stand 1, slide block 2 and spring 5 are positioned in pilot hole 4, spring 5 one end is connected with the inwall of pilot hole 4, spring 5 other end is connected with slide block 2, and slide block 2 can move horizontally along pilot hole 4；Needle body 3 is arranged on slide block 2, slide block 2 is provided with through hole 9, needle body 3 is connected with through hole 9, fluid passage 7 connects with through hole 9 or does not connects, when needle body 3 is retracted in pilot hole 4, through hole 9 and fluid passage 7 are disconnected, and when needle body 3 is stretched outside, through hole 9 connects with fluid passage 7.Spring 5, pilot hole 4 be arranged in parallel with needle body 3, and needle body 3 pin mouth is outwardly；The outer wall of needle stand 1 is provided with chute 8, chute 8 connects with pilot hole 4, shell fragment 6 one end is connected with slide block 2, and shell fragment 6 other end stretches out chute 8, and shell fragment 6 can slide along chute 8 level, as shown in Figure 4, in chute 8 and shell fragment 6 big outer the least, as it is shown on figure 3, chute 8 has the opening of big at both ends and small in middle, preferably, chute 8 opening shape is I shape.
Further, needle stand 1 is coaxially provided with installation portion 11 away from one end of needle body 3, and installation portion 11 central authorities connect with fluid passage 7.Installation portion 11 is cylindrical, and the radius of installation portion 11 is less than the radius of needle stand 1.Preferably, needle stand 1 and pilot hole 4 are cylindrical, and needle body 3 and pilot hole 4 are positioned on the axis of needle stand 1.Preferably, shell fragment 6 tilts to spring 5, and the top vertical of shell fragment 6 is arranged, and forms button block 10 at the top of shell fragment 6, and button block 10 is cylindrical.
Before using, needle body 3 is retracted in needle stand 1, as it is shown in figure 5, be arranged on syringe 12 by pin by mounting blocks 11, when needing to use needle body 3, operator presses the button block 10, and under the elastic force of spring 5, needle stand 1 slides in and out, and then promotes needle body 3 protruding；Simultaneously, owing to chute 8 is outer little interior big and opening shape is I shape, after pressing the button block 10, shell fragment 6 compresses but cannot restore, and shell fragment 6 moves horizontally along chute 8, during the opening part increased to end, shell fragment 6 is under its own resilient, shell fragment 6 outwards ejects recovery, and now, needle body 3, through hole 9 and fluid passage 7 are interconnected, operator promotes piston, can plunger medicinal liquid；When needs retraction needle body 3, operator presses the button block 10 and back promotes shell fragment 6, and then drives the inside level of needle stand 1 to slide, during the opening part increased to chute 8 end, shell fragment 8 outwards ejects recovery under its own resilient, owing to shell fragment 6 is outer, the least interior shell fragment 6 locks at the open-ended place of chute 8 greatly, stops the elastic force of spring 5, now, operator is taking off pin, simple to operate, uses safety.
