Detailed Description
Embodiments of the present utility model are described in further detail below with reference to the accompanying drawings and examples.
Examples:
As shown in fig. 1 to 6:
the utility model provides an injector with an anti-infection structure, which comprises a main body 1, a limiting part 2 and an auxiliary part 3; the main body 1 is a syringe needle tube with a cylindrical structure, and a T-shaped structure limiting groove 101 is formed in the left side and the right side of the top of the inner cavity of the main body 1; the limiting part 2 consists of a limiting piece 201 and a sliding groove 202, and the outer end of the limiting piece 201 is inserted into the inner cavity of the limiting groove 101; the auxiliary part 3 is composed of an auxiliary member 301 and a slot 302, wherein the auxiliary member 301 is a piston rod body, and the auxiliary member 301 is directly inserted into the main body 1.
As shown in fig. 2 and 3, the main body 1 further includes: a limit post 102; the limit groove 101 is of a T-shaped structure; the limiting column 102 is arranged in the middle position inside the limiting groove 101, the limiting column 102 is of a cylindrical structure with a raised middle part, an elastic connecting piece is sleeved on the periphery of the limiting column 102, and the outer end of the limiting piece 201 is of a T-shaped structure; the stopper portion 2 further includes: a chute 202; the chute 202 is arranged at the middle position inside the limiting piece 201, the chute 202 is of a cylindrical structure with a convex middle, and the inside of the chute 202 is connected with the limiting column 102 through an elastic connecting piece.
By adopting the above scheme, because the spacing groove 101 is T-shaped structure, simultaneously spacing piece 201 outer end is T-shaped structure, make spacing groove 101 can carry out spacingly with spacing piece 201, prevent that spacing piece 201 from appearing the skew, spacing post 102 is used for assisting spacing piece 201 to remove, spacing piece 201 is used for spacing auxiliary part 301, make spacing piece 201 shrink through elastic connection spare, auxiliary part 301 is through behind spacing piece 201, elastic connection spare resets spacing piece 201 again, and then carry out spacingly to auxiliary part 301, because spout 202 and spacing post 102 are middle bellied cylindrical structure, make spacing post 102 carry out spacingly in the inside removal of spout 202, auxiliary spacing piece 201.
