SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides an insert needle ware, include the needle file and impel the seat, the inside of needle file is equipped with the inner chamber, the inside of impelling the seat is equipped with the internal guide chamber, the inner chamber of needle file leads the coaxial setting in chamber with the internal guide of impelling the seat, the afterbody of needle file is equipped with axial guide slot and the radial draw-in groove that crosses with axial guide slot, be equipped with the fixture block on the lateral wall of impelling the seat, the shape of fixture block is corresponding with the shape of draw-in groove.

Preferably, the radial clamping grooves are provided with a pair and are symmetrically arranged on two sides of the axial guide groove.

Preferably, the axial guide grooves are provided with a pair and are symmetrically arranged at two sides of the needle seat.

Preferably, the pair of clamping blocks is arranged on the two sides of the propelling seat respectively and symmetrically.

Preferably, the pushing seat comprises an embedding section and an external section, the diameter of the embedding section is matched with that of the inner cavity of the needle seat, and the diameter of the external section is the same as the outer diameter of the needle seat.

Preferably, the side edge of the needle seat is provided with a reinforcing sheet.

The utility model has the advantages that: be equipped with axial guide slot and the radial draw-in groove that intersects on the needle file, the axial guide slot can be so that impel the seat and drive the syringe needle and carry out axial displacement, when the syringe needle returns the back and need fix, only needs to rotate and impels the seat for in the fixture block card on the propulsion seat goes into radial draw-in groove, can restrict the syringe needle and carry out axial displacement, the device simple structure, convenient to use.

FIG. 2 is a structural view of the propulsion seat of the present invention;

FIG. 3 is a view of the locking structure of the pushing seat and the needle seat of the present invention;

in the figure: the device comprises a needle base 1, a pushing base 2, an inner guide cavity 3, an axial guide groove 4, a radial clamping groove 5, a clamping block 6, an embedding section 7, an external connecting section 8 and a reinforcing sheet 9.

Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

As shown in fig. 1-3, a needle inserting device comprises a needle base 1 and a pushing base 2, an inner cavity (not shown in the figure) is arranged inside the needle base 1, an inner guide cavity 3 is arranged inside the pushing base 2, the inner cavity of the needle base 1 and the inner guide cavity 3 of the pushing base 2 are coaxially arranged, an axial guide groove 4 and a radial clamping groove 5 intersecting with the axial guide groove 4 are arranged at the tail of the needle base 1, a clamping block 6 is arranged on the outer side wall of the pushing base 2, and the shape of the clamping block 6 corresponds to that of the radial clamping groove 5. Axial guide slot 4 is equipped with a pair ofly altogether, the both sides of needle file 1 are located to the symmetry, the bilateral symmetry of every axial guide slot 4 is equipped with a pair of radial draw-in groove 5, fixture block 6 is equipped with a pair ofly altogether, the both sides of advancing seat 2 are located to the symmetry respectively, it includes embedding section 7 and external section 8 to advance seat 2, the diameter of embedding section 7 and the diameter phase-match of the inner chamber of needle file 1, the diameter of external section 8 is the same with the external diameter of needle file 1, the side of needle file 1 is equipped with reinforcing piece 9, reinforcing piece 9 is used for promoting the side intensity of needle file 1.
