Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a bottom view of the body of fig. 1 in accordance with the present invention.
In the figure: 1. a body; 2. a seal ring; 3. mounting holes; 4. a push rod; 5. a first stopper; 6. a second limiting block; 7. a first buffer block; 8. a second limiting block; 9. a cavity.
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.
Examples
Referring to fig. 1-2, a stable high-tightness syringe stopper comprises a body 1, a sealing ring 2 is sleeved on the outer wall of the body 1, a cavity 9 is arranged inside the body 1, a mounting hole 3 is formed in the bottom of the body 1, the mounting hole 3 is communicated with the cavity 9, a first buffer block 7 is arranged inside the cavity 9, the top of the first buffer block 7 is connected with the top end of the inner wall of the cavity 9, a push rod 4 is arranged on the body 1, one end of the push rod 4 penetrates through the mounting hole 3 to stretch into the cavity 9 and is connected with the center of the bottom of the first buffer block 7, one end of the push rod 4 stretches into the cavity 9, one side of the push rod 4 is connected with one end of a first limiting block 5, and the other side of the push rod 4 is connected with a second limiting block 6.
Furthermore, the push rod 4 is matched with the mounting hole 3, so that the connection effect can be improved.
Furthermore, the push rod 4 is fixedly connected with the first buffer block 7, so that the connection effect can be improved.
In this embodiment, body 1 top is equipped with second buffer block 8, can improve the effect of buffering, second buffer block 8 with body 1 top fixed connection.
In this embodiment, the first buffer block 7 is made of elastic rubber, and the first buffer block 7 is made of elastic rubber, so that the buffering effect can be improved.
Furthermore, the sealing ring 2 is made of rubber, so that the sealing effect can be improved.
In summary, the working principle and the working process of the stable high-tightness injector plug are that when the injector plug is used, firstly, equipment is placed in an injector matched with an external specification, then a worker can drive the body 1 and the second buffer block 8 to move in the injector by pushing the push rod 4, when the equipment is pushed to the bottom of the injector, if the worker does not see that the equipment reaches the bottom of the injector body 1 and continues to exert force, then the push rod 4 connected with the first buffer block 7 and extending into the cavity 9 in the body 1 through the mounting hole 3 can transmit the push force to the first buffer block 7, so that the push force received by the push rod 4 penetrating through the mounting hole 3 can be transmitted to the first buffer block 7, the first buffer block 7 is deformed by pressure, the first buffer block 7 can play a role of buffering, when the push force disappears, the shape of the first buffer block 7 is recovered, at this time, the push rod 4 can vertically move in the mounting hole 3 through the resilience of the first buffer block 7, when the push rod 4 is pushed to a specified position, the first limit block 5 and the second limit block 6 can abut against the inner wall of the cavity 9, so that the push rod 4 is prevented from moving in the through hole for an excessively large distance through the resilience of the first buffer block 7, the thrust of the push rod 4 can be transmitted to the second buffer block 8, the second buffer block 8 can be deformed under the pressure, the buffering effect can be improved, and the syringe can be prevented from being damaged under the pressure (when medical staff normally inject liquid medicine, the first buffer block 7 and the second buffer block 8 cannot be deformed, and only when the stopper device slides to the bottom of the syringe, the medical staff continuously exert force, the first buffer block 7 and the second buffer block 8 can be deformed under the pressure), push rod 4 with 3 phase-matches of mounting hole (push rod 4 can be in mounting hole 3 vertical reciprocating), can improve the effect of connecting, push rod 4 and 7 fixed connection of first buffer block, can improve the effect of connecting, first buffer block 7 adopts the elastic rubber material, can improve the effect of buffering, sealing washer 2 adopts the rubber material, can improve sealed effect (this product is through comprehensive disinfection processing when dispatching from the factory to can not cause the pollution to the inside liquid medicine of syringe).
