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.
As shown in fig. 1 and 2, the infusion type pipeline pressing type self-destruction device comprises a cavity base 1 and a pressing mechanism 2, wherein the pressing mechanism 2 comprises a side wall and an upper cover, the side wall of the pressing mechanism 2 is sleeved in the cavity of the cavity base 1, a through hole 13 for passing through an infusion tube is formed in the lower portion of the side wall of the cavity base 1, a knife-edge structure 21 for destroying the infusion tube is arranged at the lower end of the pressing mechanism 2, and a locking mechanism 14 for preventing the pressing mechanism 2 from rebounding after the pressing mechanism 2 is pressed down is further arranged in the side wall of the cavity base 1.
Wherein, still set up spring 3 in the cavity that the lateral wall of pressing means 2 encloses, 3 one end tops of spring are inboard at pressing means 2 upper cover, the 3 other ends of spring are installed on cavity base 1, the setting of spring is in order to avoid the self-destruction device by the mistake activation (activation is the state that can't extract after pressing means 2 presses into cavity base 1 promptly), because of the existence of spring, can be at cavity base 1, between pressing means 2, thereby avoid bumping to touch pressing means 2 and lead to the mistake activation. As shown in fig. 7, 8 and 9, a set of opposite supporting columns 11 is arranged at the upper part in the cavity of the cavity base 1, a clamping groove 12 is arranged on the supporting columns 11, the other end of the spring 3 is arranged on the clamping groove 12, and the clamping groove 12 simultaneously prevents the spring 3 from contacting with the guide pipe.
As shown in fig. 7, 8 and 9, the locking mechanism 14 includes at least two sets of locking platforms arranged at the upper and lower parts in the side wall of the cavity base 1, and each set of locking platforms is located at the opposite position in the side wall of the cavity base 1; as shown in fig. 3, 4 and 5, at least two sets of rectangular windows 23 are arranged on the upper and lower portions of the side wall of the pressing mechanism 2, and each set of rectangular windows 23 is located at the opposite position of the side wall of the pressing mechanism 2; when the cavity base 1 and the pressing mechanism 2 are assembled together, the clamping table is used for hooking the rectangular window 23. As shown in fig. 9, the bottom surface of the clamping table is a horizontal plane, the side surface of the clamping table is an inclined plane with an included angle of 30-60 degrees with the inner side of the side wall of the cavity base 1, and the clamping table is designed in such a structure that the clamping table is used for hooking the rectangular window 23 after the pressing mechanism 2 is pressed into the cavity base 1, but the pressing mechanism 2 cannot be pulled out any more because the bottom surface of the clamping table is a horizontal plane, so that the infusion tube is permanently damaged, and the self-destruction effect is achieved.
As shown in fig. 3, 4 and 6, the sidewall of the pressing mechanism 2 is further provided with a set of opposite strip-shaped notches 22, the strip-shaped notches 22 are aligned with the supporting posts 11 on the cavity base 1 when the pressing mechanism 2 is assembled with the cavity base 1, the design is such that the lower portion of the spring 3 can be pressed against the clamping grooves 12 on the supporting posts 11, and simultaneously the pressing mechanism 2 can continue to press down along the strip-shaped notches 22 until the knife-shaped structure 21 at the lower end of the pressing mechanism 2 destroys the infusion tube.
In addition, the plane that forms between a set of relative support column 11 of the inboard of cavity base 1 is parallel with through hole 13 axis, and the plane that forms between every group of ka tai of upper and lower part in the lateral wall of cavity base 1 is perpendicular with through hole 13 axis, and the design utilizes the limited space in cavity base 1 rationally like this.
The area of the upper cover of the pressing mechanism 2 is larger than the area of the cylindrical section surrounded by the side wall of the cavity base 1, so that the pressing mechanism 2 presses downwards along the cavity base 1 until the upper cover of the pressing mechanism 2 is in quick contact with the upper part of the cavity base 1, that is, the pressing is finished, the infusion tube is damaged, and the operation is convenient.
As shown in fig. 1-4, the blade-like structure 21 used in the present embodiment is a sawtooth, wherein fig. 3 shows dense sawtooth and fig. 4 shows sparse sawtooth. In practice, the blade-like structure 21 is not limited to serrations, but may be a ribbed structure with blades, as long as the infusion tube can be broken.
The working principle of the invention is as follows:
according to the above-mentioned mounting structure, as shown in fig. 1, the self-destruction device is in an inactivated state, and the saw teeth at the bottom of the pressing means 2 are temporarily positioned above the through hole 13 through which the infusion tube passes, and the infusion tube is not destroyed. The spring 3 is arranged on the clamping groove 13 of the base, and the pressing mechanism 2 is arranged on the cavity base 1, so that the rectangular window 23 at the uppermost side of the pressing mechanism 2 hooks the clamping table at the uppermost side of the cavity base 1.
As shown in fig. 2, when the pressing mechanism 2 is pressed down, the self-destruction device is activated, so that the rectangular windows 23 on the upper and lower sides of the pressing mechanism 2 hook the clamping platforms on the upper and lower sides of the cavity base 1, the pressing mechanism 2 is completely locked, and the infusion tube is tightly pressed under the saw teeth of the pressing mechanism 2 to be destroyed (the infusion tube is not shown in the figure). Due to the action of the clamping table in the cavity base 1, the pressing mechanism 2 can not be pulled out of the cavity base 1, so that the infusion tube is permanently damaged, the self-destruction effect is achieved, and the edge-shaped structure 21 is utilized, so that the infusion tube can be permanently damaged even if the pressing mechanism fails or is artificially damaged.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
