Detailed description of the invention
As shown in Figures 1 and 2, the structure of Glass syringe organ pipe 2 of the present utility model and the structure of used glass syringe are essentially identical. Plug 1 and push rod 7 are Split type structure, are threadably secured between the two and connect as one. In order to be able to store medicinal liquid, the conehead 4 of Glass syringe organ pipe 2 front end is set with a Capsule 5, as the lid of blockading of bottom face. After being filled into medicinal liquid 3 in advance in Glass syringe organ pipe 2, the other end of Glass syringe organ pipe 2 is provided with plug 1, and plug 1 is arranged in Glass syringe organ pipe 2 as the lid of blockading of the medicinal liquid 3 in Glass syringe organ pipe 2. When only using, plug 1 and push rod 7 could be threaded connection.
In order to be able to the centre bore making Capsule 5 can effectively seal conehead 4, the interior hole end surface of Capsule 5 is provided with an interior plug 6 corresponding with the centre bore of conehead 4.Interior plug 6 inserts the centre bore of conehead 4, can play the effect of blockading well.
In order to improve the effect of blockading of Capsule 5 further, the centre bore of conehead 4 can make the stepped hole that outer imperial palace is little. Thus can make the interior plug 6 in Capsule 5 be inserted into conehead 4 centre bore exit orifice in the exit orifice of centre bore of conehead 4 be circular hole.
Being provided with cavity 11 inside plug 1, cavity 11 extends downward and is provided with opening 14 bottom plug 1, and the periphery of plug 1 is provided with two circle sealing rings, is respectively located at the upper sealing ring 12 on plug 1 upper periphery and the lower seal 13 being located on plug 1 lower end peripheral. The top of plug 1 can be coniform.
Opening 14 place bottom plug 1 is provided with chamfering, and the angle of chamfering is 40 �㡫60 ��, it is preferred to 45 ��.
When the top of plug 1 is coniform, the distance between upper sealing ring 12 and lower seal 13 and plug 1 ratio highly is 2: 3. When the top of plug 1 is plane, the distance between upper sealing ring 12 and lower seal 13 and plug 1 ratio highly is 0.8: 1. Ratio is reasonable, and plug 1 is not easy deformation so in use.
Plug encloses sealing ring by two and seals, and under equal conditions, its sliding capability is good, and in push-and-pull process, plug is not easy deformation, manufactures conveniently, and the top of plug is divided into plane and coniform, applied widely.
Push rod 7 includes push rod main body 71, is arranged in the plug connecting portion 72 of push rod main body 71 end, is arranged in the promotion end face 73 of push rod main body 71 end side, it is circular for promoting end face 73, and diameter is more than the diameter of section of push rod main body 71, promoting end face 3 circumferential section to have the chamfering structure 74 bending towards push rod main direction, chamfering structure 74 is 1/4 circular arc.
Plug connecting portion 2 end face is to the chamfering structure 4 most proximal end distance length 1cm more than syringe cylinder.
Bend towards the chamfering structure of push rod main direction owing to promoting the circumferential section of end face to have in push rod, this design can avoid the root face between the circumferential section of push rod end face and thumb to contact, and increases the comfort level of thumb.
The foregoing is only preferred embodiment of the present utility model, invention is merely illustrative, and nonrestrictive. Those skilled in the art is understood, and it can be carried out many changes in the spirit and scope that invention claim limits, amendment, even equivalence, but falls within protection domain of the present utility model.
