In the attached drawing, the pipe comprises a pipe body 1, a pipe body 2, a pipe cap 3, a first convex ring 4, a cushion block 5, a second convex ring 6, a jade ring 7, a lantern ring 8, a pipe plug 9, a first limiting block 10, a second limiting block 11 and a scraping ring.

Detailed Description

As shown in fig. 1-3, the utility model provides a micro blood collection tube with a buckle structure, which comprises a tube body 1 with an opening at one end and a tube cap 2 arranged on the opening of the tube body 1 for sealing, wherein the tube cap 2 and the tube body 1 are clamped by the buckle structure, the buckle structure comprises a first convex ring 3 and a cushion block 4 arranged on the inner wall of the tube cap 2, a second convex ring 5 arranged on the outer wall of the tube body 1, the position of the second convex ring 5 corresponds to the position of the cushion block 4, one surface of the cushion block 4 facing the center of the tube cap 2 is an arc surface, and the cushion block 4 is arranged on the inner side of the first convex ring 3.

The body 1 is blocked 3 inboards of first bulge loop in the pipe cap 2 with the help of second bulge loop 5, forms the chucking, and at this moment, second bulge loop 5 is located the cambered surface of cushion 4, and the cambered surface of cushion 4 can lead to second bulge loop 5, lets comparatively laborsaving when pulling out pipe cap 2, does not influence the chucking degree of second bulge loop 5 simultaneously.

As shown in fig. 2-3, the thickness of the spacer 4 is not greater than the thickness of the first collar 3.

The thickness that cushion 4 is the biggest is the same with the thickness of first bulge loop 3, can not cause the hindrance when second bulge loop 5 card is gone into, and the central point of 4 cambered surfaces of cushion puts the minimum or thinnest position of cushion, and the back is put in place to pipe cap 2 card, and second bulge loop 3 is located the position of the interior downhill path of orientation pipe cap 2 of 4 cambered surfaces of cushion, can not rock up and down after the pipe cap 2 chucking like this.

As shown in fig. 1-3, the center of the arc surface of the cushion block 4 is coplanar with the inner wall of the pipe cap 2.

The cambered surface central point of cushion 4 puts the lowest of cushion 4, and second bulge loop 3 is located the position of the 4 cambered surfaces of cushion towards the interior downhill path of pipe cap 2, even after the chucking, pipe cap 2 still can receive an inside gliding power with the help of 4 cambered surfaces of cushion, makes pipe cap 2 and 1 buckle of body more stable, and is compacter.

As shown in fig. 2-3, the buckle structure further comprises a wall ring 6 arranged on the outer wall of the pipe body 1 and a lantern ring 7 arranged at the opening end of the pipe cap 2, and the position of the wall ring 6 corresponds to and is matched with the position of the lantern ring 7.

After the pipe cap 2 and the buckle of the pipe body 1, the wall ring 6 on the outer wall of the pipe body 1 is embedded into the lantern ring 7 on the pipe cap 2 to form a limiting structure, and forms two opposite forces in cooperation with the cushion block 4 and the second convex ring 5, so that the buckle of the pipe cap 2 and the buckle of the pipe body 1 is more compact.

As shown in fig. 2-3, a pipe plug 8 is arranged in the pipe cap 2, and the pipe plug 8 is adapted to the opening of the pipe body 1.

The sealing effect of pipe cap 2 and body 1 can be guaranteed to stopcock 8, and behind the buckle, stopcock 8 fills in the opening of body 1 and forms sealedly.

As shown in fig. 2-3, the buckle structure further includes a first limiting block 9 disposed on the outer wall of the pipe body 1 and a second limiting block 10 disposed on the inner wall of the pipe cap 2, the first limiting block 9 and the second limiting block 10 correspond horizontally, the first limiting block 9 is disposed at the upper end of the first convex ring 3, and the second limiting block 10 is disposed inside the cushion block 4 and spaced from the cushion block 4.

Behind pipe cap 2 and the 1 chucking of body, first stopper 9 card is gone into between the second stopper 10, and a plurality of first stoppers 9 and a plurality of second stopper 10 intercrossing form spacing each other, take place to rotate by a wide margin behind avoiding pipe cap 2 and the 1 buckle of body to influence sealed effect.

As shown in fig. 2-3, the opening end of the pipe body 1 is provided with a scraping ring 11, and the scraping ring 11 is of a semicircular structure and has the same inner diameter and outer diameter as the pipe body 1.

Scraping ring 11 can be favorable to the convenience when taking a blood sample, can scrape the point of bleeding with the help of scraping ring 11 and get, and it is more convenient to use.
