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.

Referring to fig. 1-5, the present invention provides a technical solution: microinjector based on 5G technology, including push rod 1, piston rod 2 and first barrel 3, the bottom swing joint of first barrel 3 has second barrel 5, the bottom swing joint of piston rod 2 has rubber buffer 4, the bottom swing joint of second barrel 5 has syringe needle 6, movable rod 7 has all been cup jointed in the activity at the both ends of push rod 1, the bottom swing joint of movable rod 7 has movable block 11, the inside one end fixedly connected with fixed block 13 of movable rod 7, the bottom screw thread of push rod 1 has cup jointed first bolt 8, the inside other end swing joint of movable rod 7 has connecting rod 14, the inside other end swing joint of movable rod 7 has first spring 12.

In this embodiment, because the size of the hand of a person is different, and the length of the push rod 1 is generally fixed, when a person with a small hand uses the microinjector, the use experience is poor, therefore, the length of the push rod 1 needs to be adjusted, the first bolt 8 is rotated to drive the top of the first bolt 8 to start moving in the direction away from the bottom of the push rod 1 until the top of the first bolt 8 completely moves away from the bottom of the movable rod 7, at this time, the movement of the movable rod 7 is not limited, the movable rod 7 is pulled to drive one end of the movable rod 7 to start moving in the direction close to the inside of the push rod 1, during the movement of the movable rod 7, one end of the movable block 11 can move to contact with the other end of the push rod 1 to continue moving, so that the first spring 12 is compressed to a certain extent, during the movement, the other end of the movable block 11 can move to contact with the other end of the connecting rod 14, at the moment, the movement of the movable rod 7 stops, the first bolt 8 rotates reversely, the top of the first bolt 8 is driven to move to contact with the inside of the push rod 1, the adjustment of the position of the movable rod 7 on the outer surface of the push rod 1 is completed, and when a person with a large hand shape uses the microinjector, the operation is reversed.

Specifically, the top swing joint of first barrel 3 has second telescopic link 10, and first telescopic link 9 has been cup jointed in the inside activity of second telescopic link 10, and the other end swing joint of first telescopic link 9 has connecting block 15, and the bottom swing joint of connecting block 15 has stopper 16, and the other end screw thread of second telescopic link 10 has cup jointed second bolt 18, and the surface swing joint of second bolt 18 has second spring 17.

In this embodiment, when the piston rod 2 of the microinjector is pulled to suck a sample, since the protection effect on the piston rod 2 is not significant, the piston rod 2 is easily bent and deformed, which affects the use of the microinjector, and therefore needs to be protected, because the bottom of the second telescopic rod 10 is attached to the top of the first barrel 3, the top of the first telescopic rod 9 is attached to the bottom of the push rod 1, by rotating the second bolt 18, one end of the second bolt 18 is driven to move in a direction away from the inside of the connecting block 15, during the movement of the second bolt 18, the second spring 17 is stretched to a certain extent until one end of the second bolt 18 is completely separated from the inside of the connecting block 15, at this time, the movement of the first telescopic rod 9 and the connecting block 15 is not limited, the push rod 1 is pulled, the piston rod 2 and the rubber plug 4 are driven to start to move inside the first barrel 3, meanwhile, the movement of the push rod 1 also drives the first telescopic rod 9 to move inside the second telescopic rod 10, so that the piston rod 2 is protected.

Specifically, the bottom of the push rod 1 is provided with a clamping groove matched with the bottom of the first bolt 8, and the other end of the inner part of the movable rod 7 is provided with a connecting rod 14 matched with the other end of the inner part of the movable rod.

In this embodiment, the bottom of the push rod 1 is attached to the top of the first bolt 8, so that an external force is applied to the first bolt 8 to drive the push rod 1 to start moving; so that the other end of the connecting rod 14 is attached to the other end of the inside of the movable rod 7, and when the other end of the movable block 11 moves and contacts one end of the connecting rod 14, the movement of the movable block 11 is stopped, so as to prevent the first spring 12 from generating unrecoverable deformation.

Specifically, the movable rod 7 is in a hollow rectangular shape, and one end of the movable rod 7 is provided with a round hole matched with the push rod 1.

In this embodiment, the movement of the movable rod 7 on the outer surface of the push rod 1 is facilitated.

Specifically, the second telescopic rod 10 is in the shape of a hollow cylinder, and a through hole matched with the first telescopic rod 9 is formed in the top of the second telescopic rod 10.

In this embodiment, the first telescopic rod 9 can move inside the second telescopic rod 10 conveniently.

Specifically, the connecting block 15 is shaped as a hollow rectangle, and the other end of the connecting block 15 is provided with a groove matched with one end of the second bolt 18.

In this embodiment, it is convenient for one end of the second bolt 18 to move inside the connecting block 15, thereby fixing the moving position of the first telescopic rod 9.

Specifically, the number of the connecting blocks 15 is two, and the two connecting blocks 15 are respectively located at two ends of the first telescopic rod 9.

In this embodiment, through setting up two connecting blocks 15 for first telescopic link 9 can keep steady motion in the inside of second telescopic link 10, can not take place big rocking.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
