Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention provides a transfusion tube connector which comprises a hollow cylindrical connector tube 1 and a buckle sleeve 2, wherein symmetrical conical end heads 3 are arranged at two ends of the connector tube 1, the buckle sleeve 2 can be sleeved on the conical end heads 3, at least two groups of buckle rib plates 4 which are oppositely arranged are arranged in the middle of the connector tube 2, one ends of the buckle rib plates 4 are provided with hooks 5 used for fixing the buckle sleeve 2, the other ends of the buckle rib plates 4 are hinged with U-shaped fixing seats 6, the buckle rib plates 4 can rotate along the fixing seats 6, and the fixing seats 6 are fixed on the connector tube 1.

The tip of different transfer lines of toper end 3 interpolation, tentatively fixed back, buckle cover 2 is along sliding, and along with 3 diameter grow of toper end tightly fix the both ends at adapter tube 1 with the tip of transfer line.

The fixing seat 6 with still be equipped with fixed plate 7 between the joint pipe 1, fixed plate 7 is fixed 1 lateral wall of joint pipe, be equipped with waist hole 8 on the fixed plate 7, fixing seat 6 passes through 8 fix with screw in waist hole 7 is last. According to the transfer line of different specifications, under the certain condition of buckle floor 4 length, the position of nimble removal fixing base 6 guarantees the fixed stability of transfer line tip, and the flexibility of use of device obtains guaranteeing.

And the outer side wall of the conical end head 3 is provided with an anti-skid surface. The setting of antiskid face prevents effectively that buckle floor 4 from sliding along the wedge face of toper end 3 and causing not hard up, further guarantees fixed position's reliability.
