In conjunction with the accompanying drawings, the present invention is further explained in detail.These attached drawings are simplified schematic diagram, only with
Illustration illustrates basic structure of the invention, therefore it only shows the composition relevant to the invention, direction and referring to (for example,
Upper and lower, left and right, etc.) can be only used for helping the description to the feature in attached drawing.Therefore, it is not adopted in restrictive sense
With following specific embodiments, and claimed theme is only limited by appended claims and its equivalent form
Range.
Embodiment 1
As shown in Figure 1-3, a kind of Single-Use Auto-Disable Syringes, including syringe 1, core bar 2, piston 3 and syringe needle 4,
The syringe needle 4 is fixed on the bottom end of syringe 1, and the top of the syringe 1 has the injecting cavity 1-1 of opening upwards, the injecting cavity
1-1 is connected to syringe needle 4, and the piston 3 is slidably arranged in the injecting cavity 1-1, is recessed on the outer peripheral surface of the piston 3 limited
Position slot 3-1, the inner wall of the injecting cavity 1-1 are protruding with the positive stop strip 1-11, the positive stop strip 1- to match with limiting slot 3-1
11 are located in limiting slot 3-1, and the upper end of the piston 3 offers cavity 3-2 downwards, are located at cavity 3-2's on the piston 3
Position between bottom of chamber and the lower end surface of piston 3 is punctured part 3-3, and the core bar 2 is threadedly coupled with the cavity 3-2 of piston 3, institute
The channel 2-1 in core bar 2 with opening upwards is stated, the channel 2-1 is connected to cavity 3-2, and the bottom end of the core bar 2 has cone
Shape tip 2-2.
Further, the upper and lower ends of the piston 3 are respectively equipped with upper press ring 5 and lower pressure ring 6, the upper press ring 5 and work
The upper end face contact of plug 3, the intermediate position of the upper press ring 5 has extended downwardly connection ring 5-1, the periphery of the connection ring 5-1
Face is contacted with the inner wall of cavity 3-2, and the core bar 2 is threadedly coupled with the inner peripheral surface of connection ring 5-1；
